Description

Technical Field

[0001] This utility model relates to the field of rail transit door technology, and in particular to a load-bearing drive mechanism detection device. Background Technology

[0002] High-speed trains and other rail transit vehicles mostly adopt a concealed sliding door structure. Concealed sliding doors are characterized by simple structure, low failure rate, and high safety performance. The load-bearing drive mechanism is used to control the opening and closing of the sliding door. The load-bearing drive mechanism is equipped with a cylinder, and the power output end of the cylinder is connected to the sliding door, so that the sliding door can be opened and closed under the drive of the cylinder.

[0003] In the existing technology, the load-bearing drive mechanism lacks dedicated testing equipment after production, making it impossible to conduct unified debugging. This results in poor consistency in the opening and closing time of vehicle doors, affecting vehicle scheduling and posing safety hazards. Utility Model Content

A first slider 6 is slidably installed on the first guide rail 5. A guide assembly is fixedly installed on the first slider 6. The guide assembly includes a base plate 7, which is fixedly installed on the first slider 6. The guide assembly is used to simulate the connection between the load-bearing drive mechanism 4 and the carriage door. Under the drive of the load-bearing drive mechanism 4, the base plate 7 moves back and forth along the first guide rail 5 to simulate the opening and closing of the carriage door.

[0023] In this embodiment, a second guide rail 8 is fixedly installed at the top left and right ends of the base plate 7. The second guide rail 8 is perpendicular to the first guide rail 5. A second slider 9 is slidably installed on the second guide rail 8. An adjusting plate 10 is fixedly installed on the second slider 9. A plurality of sets of light rods 11 are fixedly installed on the top of the adjusting plate 10. Preferably, there are two sets of light rods 11, which are located diagonally opposite to each other on the adjusting plate 10. A bushing 12 is slidably installed on each light rod 11. The bushing 12 is fixedly installed on the lifting plate 13. A fixed base 14 is bolted to the top, and a connecting rod 15 is hinged to the top of the fixed base 14. A carrying frame 16 is bolted to the end of the connecting rod 15 away from the fixed base 14. The carrying frame 16 is bolted to the movable end of the load-bearing drive mechanism 4. The adjusting plate 10 moves back and forth on the base plate 7 via the second slider 9. The lifting plate 13 can move up and down along the smooth rod 11. The connecting rod 15 can rotate on the fixed base 14, thereby flexibly adjusting the position of the connecting rod 15 to suit different specifications of the load-bearing drive mechanism 4.

[0024] In this embodiment, the end of the connecting rod 15 near the fixed seat 14 is provided with a threaded part 151. A fastening nut 17 is installed on the threaded part 151 by threaded engagement. The fastening nut 17 is located on the side of the fixed seat 14 away from the connecting rod 15. A tightening table 171 is welded to the fastening nut 17. The operator tightens the fastening nut 17 by tightening the tightening table 171.

The load-bearing drive mechanism 4 drives the base plate 7 to move back and forth on the first guide rail 5, simulating the opening and closing of the carriage door. The operator records the time of the reciprocating movement of the base plate 7 with a stopwatch. If the test result is out of tolerance, the load-bearing drive mechanism 4 is adjusted to make the opening and closing time conform to the standard. Therefore, after the load-bearing drive mechanism 4 is produced, it is uniformly tested and debugged by this utility model, which helps to improve the consistency of the load-bearing drive mechanism.
