Product Description
operating principle
The hydraulic quick coupler of an excavator is mainly composed of parts such as the main frame, connecting pins, hydraulic cylinders, and locking mechanisms. When it is necessary to replace the working device, the hydraulic system of the excavator is used to control the action of the hydraulic cylinder, so that the connecting pin retracts and unlocks the original working device. Then, align the new working device with the connection part, and control the hydraulic cylinder to extend the connecting pin again to firmly connect the new working device with the excavator. The entire process realizes rapid connection and disassembly through hydraulic drive.
structural features
Main structure: Made of high-strength alloy steel, it has sufficient strength and rigidity to bear various loads of the working device during operation. Its structural design is compact, and the external dimensions match the connection part of the excavator to ensure overall stability and reliability after installation.
Connecting pin and locking mechanism: The connecting pin is usually subjected to special heat treatment, with high surface hardness and good wear resistance, ensuring firm connection. The locking mechanism adopts advanced mechanical or hydraulic locking principles and can effectively prevent accidental retraction of the connecting pin during operation, ensuring safe and reliable connection between the working device and the excavator.
Hydraulic system: Compatible with the hydraulic system of an excavator. Connected to the hydraulic pump of the excavator through oil pipes to receive and transmit hydraulic power. The hydraulic cylinder has good sealing performance and can work stably under high pressure to ensure the rapid and accurate movement of the connecting pin.
application scenarios
Construction: In operations such as building foundation excavation, earthwork engineering, and material handling, work attachments such as buckets and log grapples can be quickly switched according to the construction progress and specific tasks to improve construction efficiency.
Road engineering: In the process of road construction and maintenance, such as when excavating ditches, laying pipelines, and clearing obstacles, it is convenient to replace different working devices to meet diverse construction needs.
Mine exploitation: In mine operations, working devices such as crushing hammers and hydraulic shears need to be frequently replaced. The hydraulic quick coupler can quickly achieve replacement, reduce equipment downtime, and improve mining efficiency.
Our Advantages
Performance advantages
Quick replacement: Significantly shortens the time for replacing work attachments. Traditional replacement methods may take dozens of minutes or even longer, while using a hydraulic quick coupler usually only takes a few minutes to complete the replacement, improving the working efficiency of excavators.
Strong versatility: It can be adapted to various models and specifications of excavator working devices, such as buckets, breakers, hydraulic shears, wood grabs, etc. After an excavator is equipped with a hydraulic quick coupler, the working device can be quickly switched according to different construction needs, improving the versatility and utilization rate of the equipment.
Easy operation: The connection and disconnection of the hydraulic quick coupler can be easily operated through the control handle in the excavator cab. Operators do not need to perform complicated manual operations, reducing labor intensity. Moreover, the operation process is safe and reliable.
