Description

Technical Field

[0001] The utility model relates to the technical field of locking mechanisms, in particular to a pull arm locking mechanism for a carriage-dump garbage truck. Background Art

[0002] The pull arm of a garbage truck is a mechanism used by a sanitation garbage truck to pull a garbage bin. Existing pull arms of garbage trucks, such as the adjustable sanitation garbage truck pull arm disclosed in the utility model patent with the publication number CN203753740U and a two-stage telescopic carriage-dump garbage truck pull arm hook disclosed in the utility model patent with the publication number CN216271247U, can all achieve pulling the garbage bin onto the sanitation garbage truck or putting down the garbage bin on the sanitation garbage truck.

[0003] However, it is found in the use process that after pulling the garbage bin onto the sanitation garbage truck, the hydraulic equipment needs to run continuously to ensure the stability of the garbage bin. And when the hydraulic equipment fails, the garbage bin is likely to fall off, resulting in poor practicability. Therefore, there is an urgent need for a pull arm locking mechanism for a carriage-dump garbage truck to improve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a pull arm locking mechanism for a carriage-dump garbage truck, which moves the garbage bin onto the sanitation garbage truck through the pull arm, locks the pull arm through a limiting mechanism to ensure the stability of the pull arm. After the pull arm moves the garbage bin onto the sanitation garbage truck, when the limiting mechanism is not operating, the alarm mechanism reminds the staff to check the limiting mechanism, thereby improving the practicability of the equipment.

[0007] The garbage bin is moved onto the sanitation garbage truck through the pull arm, the pull arm is locked through the limiting mechanism to ensure the stability of the pull arm. After the pull arm moves the garbage bin onto the sanitation garbage truck, when the limiting mechanism is not operating, the alarm mechanism reminds the staff to check the limiting mechanism, thereby improving the practicability of the equipment.

The driving motor is installed on the sanitation garbage truck, one end of the one-way wheel is installed on the output shaft of the driving motor, the toothed ring is sleeved on the one-way wheel, the top end of the rack is connected to the bottom end of the limiting column, and the toothed ring is meshed with the rack; by attracting the two sets of second permanent magnet blocks with the first permanent magnet block, the rack drives the toothed ring to rotate, so that one end of the limiting column is inserted into the pulling arm. Then, by turning on the driving motor, the one-way wheel drives the toothed ring to rotate, and through the meshing transmission of the toothed ring and the rack, one end of the limiting column is pulled out of the pulling arm, thereby improving the practicability of the equipment.

[0010] Preferably, the alarm mechanism includes a baffle, a pressure sensor, a spring and an alarm. The baffle is installed at the other end of the limiting column, the pressure sensor is installed on the baffle, the spring is installed on the spring, and the alarm is installed on the driving motor; when one end of the limiting column is inserted into the pulling arm, the spring hits the guide frame, and at the same time, after the pressure sensor detects the pressure, the alarm remains in the closed state. After the pulling arm is reset, the pressure sensor does not detect the pressure, and the alarm operates to send an alarm to remind the staff, thereby improving the practicability of the equipment.

[0011] Preferably, two sets of rubber rings are further included, and the two sets of rubber rings are respectively sleeved on the two sets of limiting columns; the friction between the limiting columns and the pulling arm is increased, thereby improving the stability of the equipment.

[0012] Preferably, buffer pads are arranged at the front end and the rear end of the first permanent magnet block; the impact force of the two sets of second permanent magnet blocks on the first permanent magnet block is reduced, thereby improving the practicability of the equipment.

[0013] Preferably, the two sets of limiting columns are both made of solid metal material.

One end of the support arm is rotatably installed on the sanitation garbage truck, the hook is installed at the other end of the support arm, one end of the hydraulic system is rotatably installed on the sanitation garbage truck, and the other end of the hydraulic system is rotatably installed on the support arm. By extending the hydraulic system, the support arm rotates. The hook hooks the garbage bin, and then by contracting the hydraulic system, the support arm rotates in the reverse direction and resets, pulling the garbage bin onto the sanitation garbage truck, thereby improving the practicability of the equipment.

[0015] Compared with the prior art, the beneficial effect of the present utility model is that the garbage bin is moved onto the sanitation garbage truck through the pulling arm, and the pulling arm is locked by the limiting mechanism to ensure the stability of the pulling arm. After the pulling arm moves the garbage bin onto the sanitation garbage truck, when the limiting mechanism is not operating, the alarm mechanism reminds the staff to check the limiting mechanism, thereby improving the practicability of the equipment.
