Problems solved by technology

[0003] The inventor found the following problems in the above traditional method: 1) There are great potential safety hazards in operation, the impact position of the pendent hammer is inaccurate, the impact force is unstable, and it is easy to cause injury and disability accidents; 2) Maintenance operations are very time-consuming and inefficient, seriously affecting daily There are many uncontrollable factors in production work arrangement and maintenance time
3) Due to the long maintenance time of such failures, the maintenance site and maintenance shared resources (crown, forklift, etc.) will be occupied for a long time, and human resources, space resources, equipment resources, etc. will be occupied for maintenance, which is not conducive to daily production maintenance, etc.

Embodiment 1

[0033] This embodiment provides a mobile impact type large pin shaft replacement device, wherein the large pin shaft refers to the traction pin connecting the rear axle of the dump truck and the girder; figure 1 As shown, the replacement device includes an impact device body, an adjustment mechanism 3, a fine-tuning mechanism 4, a mobile support assembly, a hydraulic power source 1, and an electrical control box 7. The mobile support assembly is installed at the bottom of the impact device body, and the adjustment mechanism 3 is connected to the impact device. Below the device body, the fine-tuning mechanism 4 is installed on one end of the impact device body.

[0034] An electrical control box 7 is installed on one side of the impact device body, and the impact device body is connected to a hydraulic power source 1 through a pipeline. The electrical control box 7 mainly includes electronic components such as a relay, a current controller, a warning light, an emergency stop bu...

Embodiment 2

[0050] This embodiment provides a mobile impact type large-scale pin replacement method. Using the replacement device described in Embodiment 1, the motor is controlled by the remote controller to rotate to drive the pump station to output hydraulic power, and the power is distributed by controlling the solenoid valve. The mechanism 5 outputs the impact force of the cycle, and the impact moving mechanism 5 transmits the impact force to the impact drill rod 2. After the accurate working position adjustment, the impact drill rod 2 impacts the traction pin, so as to realize the installation or disassembly operation.

Abstract

The invention discloses a movable impact type large pin shaft replacement device and method. According to the technical scheme, the movable impact type large pin shaft replacement device comprises an impact device body, a fine adjustment mechanism, an adjustment mechanism and a movable supporting assembly. The impact device body comprises an impact drill rod and an impact moving mechanism, and the impact moving mechanism can provide circulating reciprocating power for the impact drill rod. The fine adjustment mechanism comprises a pulley making contact with the bottom of the impact drill rod, and the pulley is connected with the impact moving mechanism through a connecting support. The adjustment mechanism is located below the impact drill rod and comprises a lead screw rotationally connected with the impact moving mechanism, and the lead screw is provided with a manual pull rod. The movable supporting assembly is used for supporting the impact device body and installed at the bottom of the impact moving mechanism. The safety of maintenance operation can be improved, the working efficiency is improved, and the resource utilization rate is increased.

Description

technical field [0001] The invention relates to the technical field of equipment maintenance, in particular to a mobile impact type large pin replacement device and method. Background technique [0002] The traction pin is a key component connecting the rear axle of the dump truck and the girder, and bears the tension and impact of heavy cargo. Generally, the diameter of the traction pin is φ140mm, the length is 500mm, and the weight is about 45Kg, which is relatively heavy. In daily vehicle troubleshooting, there are usually failures such as traction bearing fragmentation, traction seat cracks, traction bearing splint bolts broken, and traction pin wear. In these cases, it is usually necessary to replace or drive out the traction pin for maintenance. When removing the traction pin for daily maintenance, the traditional method is to use the crown block to hang the rear of the vehicle body, adjust the gap between the traction pin and the lug of the traction seat of the beam, ...
