[0016] Working principle: When repairing the strut, the motor is started. When the output end of the motor rotates, it can drive the threaded rod to rotate. After the threaded rod rotates, it can drive the sliding block to move, and then drive the moving frame to move by driving the sliding block. When the moving frame moves, it can drive the hydraulic cylinder to move. When the hydraulic cylinder moves to the bending part of the strut, the hydraulic cylinder is started, and the output end of the hydraulic cylinder moves downward, thereby driving the installation column to move downward. The downward movement of the installation column drives the extrusion correction head to move downward, so that the strut can be physically corrected; When the cam is in the position where the locking cam is moved, the locking cam is pushed back into the locking cam and the locking cam is engaged with the locking cam, so that the locking cam can be pushed out of the locking cam and the locking cam is engaged with the locking cam. As the movable frame moves, the push-pull bent rod can be driven to move, thereby driving the movable plug to move inside the gas cylinder. When the movable plug moves toward the push-pull bent rod, the one-way valve 1 is closed and the one-way valve 2 is opened, so that the connecting hard pipe on the one-way valve 2 can be used to evacuate gas. When the movable plug moves toward the side close to the connecting hard pipe, the one-way valve 2 is closed and the one-way valve 1 is opened, so that gas can be filled in through the connecting hard pipe on the one-way valve 1. The connecting hard pipe on the one-way valve one fills the gas into the interior of the high-pressure tank, and the connecting hard pipe on the one-way valve two is used to extract the gas in the negative pressure tank. If it is necessary to spray the protective agent, the electric valve on one side of the high-pressure tank is opened, and the air inside the high-pressure tank will enter the interior of the liquid tank through the electric valve, thereby increasing the air pressure inside the liquid tank. At this time, the nozzle is opened, and the protective liquid will be sprayed out through the nozzle using the connecting hose, so that the protective agent can be sprayed on the outside of the support rod, and then the support rod can be protected from damage during physical correction. At the same time, the electric valve on the negative pressure tank is opened, and pressure is generated inside the dust collecting box at this time, and then the ventilation hose can be used to transmit suction to the top of the dust collector, so that the sprayed protective liquid can be extracted, and then the protective agent can be prevented from floating in the air. Therefore, while protecting the support rod, it can also prevent the protective agent from floating in the air and affecting the health of the staff; When the support rod is clamped, the electromagnetic valve is opened, and the gas in the high-pressure tank will enter the interior of the ventilation tube through the three-pipe connection, so that the gas can be filled into the interior of the fixed box through the connecting pipe, and then the limit sliding plate can be pushed to move toward the middle of the mounting frame, and then the abutment plate can be driven to move toward the middle of the mounting frame through the movable plate, and then the support rod can be clamped in the middle of the abutment plate. If the support rod is loosened, the one-way valve is opened. At this time, the electromagnetic valve is closed and the one-way valve is opened. Therefore, the air in the fixed box is discharged through the one-way valve, and the limit sliding plate is pulled back under the action of the pushing spring, and then the movable plate can be pulled back to the inside of the fixed box, and then the abutment plate can loosen the support rod.

[0017] The present invention provides a hood support rod repair device for a vehicle pedestrian protection device. It has the following beneficial effects: 1. The present invention uses an extrusion correction head to physically repair the strut under the action of a hydraulic cylinder, and during the repair process, a clamping mechanism squeezes and clamps the strut, so that the strut can be kept stationary during the repair process. At the same time, a correction head replacement mechanism is used to use different extrusion correction heads for struts of different thicknesses, and the repaired strut can be detected by using a pressure sensor and a hollow groove. Therefore, multiple functions are realized, the practicability of the device is improved, other devices are not required for processing, and the cost of repair is reduced.

[0018] 2. The present invention realizes the ability to spray a protective agent before repairing the strut through a liquid spraying mechanism, thereby being able to protect the strut during physical repair, thereby preventing damage to the strut during physical repair, thereby improving the success rate of repair. At the same time, there is no need for manual application of the protective agent, thereby reducing manual workload and improving the efficiency of repair. BRIEF DESCRIPTION OF THE DRAWINGS
