A complete guide to using the double lock connector for small excavators: detailed description of skills and steps
Small excavators play a key role in various engineering operations, and double lock connectors, as their important accessories, can make operations more efficient and convenient. The correct use of double lock connectors can not only improve work efficiency, but also ensure work safety. Next, we will introduce you to the use skills and steps of "double lock connectors for small excavators".
1. Comprehensive inspection before use
Before using the "double lock connector for small excavators", a careful inspection is essential. First, check the appearance of the connector to see if there is obvious damage, deformation or cracks. Focus on the "locking part of the double lock connector" to ensure that there is no sign of wear or looseness. If the lock is found to have problems, it may cause the attachment to fall during the operation, causing serious safety accidents.
At the same time, check whether the hydraulic pipeline is firmly connected and whether there is any leakage. The hydraulic system is the power source for the double lock connector. If the hydraulic pipeline leaks, the connector will not work properly and reduce the work efficiency. You can judge whether there is a leak by observing whether there is oil stain on the surface of the pipeline. If there is, the pipeline needs to be repaired or replaced in time. In addition, check the hydraulic oil level and quality of the excavator to ensure that the hydraulic system can operate normally.
2. Accurate steps for connecting accessories
(I) Positioning and alignment
Move the small excavator to the appropriate position so that the double lock connector is aligned with the accessories to be connected, such as buckets, breaker hammers, etc. When "connecting accessories with the double lock connector of the small excavator", ensure that the connection holes of the two are accurately aligned. This can be achieved by fine-tuning the position and angle of the excavator. This step requires the operator to have certain experience and skills. If the hole alignment is inaccurate, it will increase the difficulty of subsequent connection and even damage the connector and accessories.
(II) Initial locking
When the connection holes are aligned, operate the hydraulic control handle of the excavator to extend the front hook of the double lock connector and insert it into the front connection hole of the accessory. At this time, the front hook will automatically lock under the action of hydraulic pressure. This is the first locking. In this process, pay attention to the insertion depth and locking state of the front hook to ensure that the front hook is fully inserted and firmly locked. This can be judged by observing the locking indicator on the connector or listening to the sound when locking.
(III) Secondary locking and confirmation
After the front hook is locked, continue to operate the hydraulic control handle to rotate the rear hook card around the first pin shaft, contact and lock with the rear connecting shaft of the attachment. This is the second locking. The secondary mechanical locking of the rear hook further ensures the stability of the attachment connection. After the rear hook is locked, check the locking of the front and rear hooks again to ensure that the attachment is firmly connected. You can gently shake the excavator or attachment to feel the stability of the connection.
III. Operation skills during operation
(I) Reasonable control of force
When using a small excavator with attached attachments for operation, the excavation force should be reasonably controlled according to the operation situation. Avoid excessive force, because excessive impact force may damage the "small excavator double lock connector" and affect its service life. For example, when excavating harder soil or rock, the excavation force should be gradually increased instead of applying excessive force instantly. At the same time, pay attention to keeping the balance of the excavator to avoid the attachment falling off due to tilting or shaking.
(II) Always pay attention to the connection status
During the operation, the operator should always pay attention to the connection status of the double lock connector and the attachment. This can be confirmed by observing the monitoring device in the cab (if any) or by getting off the vehicle for regular inspection. In particular, the inspection frequency should be increased when performing some complex or high-intensity operations. If the connector is found to be loose, making abnormal sounds or other abnormal conditions, the operation should be stopped immediately for investigation and treatment.
4. The correct process for disassembling accessories
(I) Unlocking
When it is necessary to disassemble the accessories, first operate the hydraulic control handle to unlock the front hook and rear hook of the double-lock connector in sequence. During the unlocking process of "small excavator double-lock connector disassembly accessories", ensure that the unlocking action is completely in place. You can judge by observing the unlocking indicator on the connector or listening to the sound when unlocking. If the unlocking is not complete, forced disassembly may damage the connector and accessories.
(II) Removing accessories
After unlocking, operate the excavator to move the accessories smoothly. During the removal process, pay attention to the surrounding environment to prevent the accessories from colliding with other objects. At the same time, control the movement speed of the excavator to avoid shaking or falling of the accessories due to excessive speed. Place the accessories in a safe and appropriate location for next use or storage.
V. Maintenance after use
(I) Cleaning
After use, the "Small Excavator Double Lock Connector" should be cleaned in time. Remove dirt, dust, oil and other impurities on the surface of the connector. You can use brushes, detergents and other tools. Keeping the connector clean will help extend its service life and facilitate inspection the next time it is used. Pay special attention to cleaning the lock part and the connection hole to prevent impurities from entering and affecting the connection performance.
(II) Lubrication and maintenance
Regularly lubricate and maintain the double lock connector, generally once every five alternating uses. During maintenance, inject an appropriate amount of butter into each grease nozzle to ensure that the movable parts of the connector can operate smoothly. At the grab hook part, it is recommended to lubricate and maintain it twice a day. Good lubrication can reduce wear between parts and reduce the probability of failure.
(III) Inspection and maintenance
Regularly check the various components of the double lock connector, such as whether the bolts are loose, whether there are gaps in the steel plate, whether the tiger's mouth and the grab hook are worn and deformed, and whether the oil cylinder is leaking. A comprehensive inspection should be carried out after every 120 hours of work. If any problems are found, repairs or parts should be carried out in time. For example, if the bolts are found to be loose, they should be tightened in time; if the grab hook is severely worn, it should be replaced in time. Timely inspection and maintenance can ensure that the "Small Excavator Double Lock Connector" is always in good working condition.
