Description

Technical Field

[0001] This utility model relates to the technical field of lock testing equipment, specifically a railway passenger car lock life testing device. Background Technology

[0002] With the rapid development of high-speed railways, passenger dedicated lines, heavy-haul freight lines, and urban rail transit in my country in recent years, the production of high-speed trains, EMUs, locomotives, and urban rail trains has increased significantly. Consequently, the number of locks used in rail transit vehicles has also increased dramatically, and their reliable operation is crucial to the safety of railway operations. Due to the wide variety of lock types, models, and specifications, as well as significant differences in their structure, quality, and reliability, the demand for locks is substantial.

[0003] In addition, China Railway Corporation has issued standard technical documents such as TJ / CL443 "Provisional Technical Conditions for Railway Passenger Car Tightening Locks", TJ / CL444 "Provisional Technical Conditions for Railway Passenger Car Roof Plate External Locks", and TJ / CL445 "Provisional Technical Conditions for Railway Passenger Car Skirt Locks", which set forth technical requirements for the testing and inspection of locks used in rail transit vehicles. Therefore, testing locks used in rail transit vehicles is particularly important. Life testing in lock testing has specific requirements for the testing frequency, angle, and number of cycles, ranging from several thousand to tens of thousands. Currently, there are few life testing devices for railway passenger car locks, and most lock life testing is done manually. Each person can only conduct life testing on one lock, and the counting method is also limited to manual counting, resulting in low reliability, low work efficiency, and high manpower consumption.

[0004] Existing lock testing equipment cannot test a large number of locks simultaneously, resulting in relatively low testing efficiency. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a railway passenger car lock life testing device, solving the aforementioned technical problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a railway passenger car lock life testing device, comprising a main body, a control box mounted on the main body, a rack slidably mounted inside the control box, a transmission slider connected to the rack, a sliding groove on the transmission slider, a cover attached to the control box, a servo motor mounted at the bottom of the cover, a rotating disk mounted on the output shaft of the servo motor, an eccentric shaft protruding from the rotating disk, the eccentric shaft slidably mounted in the sliding groove, four gears rotatably mounted inside the control box meshing with the rack, a rotating shaft protruding from the gears penetrating the control box and extending to the outside, a key mounting block mounted at one end of the rotating shaft extending to the outside, a movable frame slidably mounted on the main body, a lock mounting frame mounted on the movable frame, a lead screw threadedly connected to the movable frame, one end of the lead screw abutting against the lock mounting frame.

[0009] Preferably, the main body of the device has two mutually symmetrical horizontal grooves, and a horizontal slider is slidably arranged in the horizontal grooves. The horizontal slider is mounted on a movable frame.

[0010] Preferably, the main body of the device is provided with a transmission groove, a threaded rod is rotatably installed in the transmission groove, a threaded transmission block is slidably arranged in the transmission groove, the threaded transmission block is threadedly connected to the threaded rod, and the threaded transmission block is installed at the bottom of the movable frame.

[0011] Preferably, the main body of the device is provided with a track, and the rack is slidably arranged in the track.

[0012] Preferably, the movable frame is threaded with a lead screw, the top of the lead screw is provided with a rotating handle, and the bottom of the lead screw is provided with an abutment block, which abuts against the lock mounting frame.

[0013] Preferably, the top of the cover is provided with two symmetrical handles, and the surface of the handles is covered with a rubber sleeve.

[0014] Preferably, the four gears are spaced apart in the horizontal direction.

[0015] Compared with the prior art, this utility model provides a railway passenger car lock life testing device with the following advantages: Through the cooperation of gears, racks, and transmission sliders, this utility model allows multiple locks on the lock mounting bracket on the movable frame to be connected to the keys on the key mounting blocks on the control box. A servo motor drives a rotating disk to rotate, causing the eccentric shaft to slide in the sliding groove of the transmission slider. This, in turn, causes the rack to reciprocate within the control box, resulting in the reciprocating movement of the four key mounting blocks connected to the four gear shafts. This enables life testing of multiple locks. Furthermore, the cover allows the servo motor to be moved away from the control box, facilitating the replacement of the rotating disk on the servo motor. Different sized rotating disks can be used according to testing requirements, allowing adjustment of the maximum movement range of the rack and changing the rotation angle of the key mounting blocks, thus improving the adaptability of the device.
