Description

Technical Field

[0001] The utility model relates to the technical field of vehicle transfer platforms, and more specifically to an adjustable vehicle transfer platform structure. Background Art

[0002] The car transfer platform is a steering device that moves the empty car from the loaded car line to the empty car line after unloading. It is suitable for the unloading line of the return car dumper. At present, when the railway car transfer platform is in use, the standard value of the rail gap between the rail of the car transfer platform and the rail of the fixed track bed is 6-8mm. Any gap greater or less than 6-8mm is a hidden danger that seriously affects the safety of railway operation.

[0003] Since the car moving platform equipment is installed in the open air, the track gap will change with the changes in ambient temperature. For example, in the summer when the sun is scorching, the rails expand and cause the track gap to shrink. It is easy for the rails of the car moving platform to collide with the rails of the fixed track bed, affecting the safe operation of the equipment. Therefore, the track gap needs to be adjusted. Currently, the track gap adjustment work requires tools such as sledgehammers and crowbars, and the operating personnel are required to shift the car moving platform back and forth for adjustment, which is labor-intensive and time-consuming, and needs to be improved. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an adjustable vehicle transfer platform structure to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solutions: an adjustable car moving platform structure, comprising a car moving platform body, two car moving platform rails are symmetrically fixedly installed on the top of the car moving platform body, a fixed roadbed is arranged at the left end of the car moving platform body, two fixed rails are symmetrically fixedly installed on the top of the fixed roadbed, the two car moving platform rails are located at one end of the fixed rails, one end of the outer sides of the two car moving platform rails are both installed with a rail gap adjustment mechanism, the rail gap adjustment mechanism comprises a fixed block, the fixed block is welded to one end of the outer side of the car moving platform rail, a fixed cover is fixedly installed on the right side of the fixed block, two adjustment rods are arranged inside the fixed cover, the left end of the adjustment rod extends to the left side of the fixed block, and the left end of the outer wall of the adjustment rod is provided with a scale line and a digital mark.

[0006] Furthermore, a bearing is fixedly installed in the middle of the left side of the fixed cover, a bolt is rotatably sleeved inside the bearing, a hexagonal nut is fixedly connected to the right end of the bolt, and the right end of the bolt and the hexagonal nut are integrally formed.

[0007] Furthermore, a positioning plate is fixedly connected to the left side of the inner cavity of the fixed cover, the outer wall of the adjustment rod is movably sleeved inside the positioning plate, and the left end of the bolt is rotatably connected to the middle part of the right side of the positioning plate.

[0008] Furthermore, an adjustment plate is movably sleeved inside the fixed cover, the internal thread of the adjustment plate is connected to the outer wall of the bolt, and the right ends of the two adjustment rods are symmetrically fixedly connected to the left side of the adjustment plate.

[0009] Furthermore, guide blocks are symmetrically fixedly connected to the upper and lower sides of the adjustment plate, guide grooves are symmetrically opened on the upper and lower sides of the inner wall of the fixed cover, and the outer wall of the guide block is slidably connected to the inside of the guide groove.

[0010] Furthermore, limit stops are welded to the right ends of the outer sides of the two fixed rails, and the limit stops are located at the same height as the rail gap adjustment mechanism.

[0011] Technical effects and advantages of the utility model:

[0012] 1. In the utility model, if the track gap between the rails of the moving platform and the rails of the fixed track bed is reduced due to sun exposure, the position of the adjusting rod can be adjusted by using the cooperation of the fixing block, the fixing cover, the bearing, the hexagonal nut, the bolt, the positioning plate, the adjusting plate and the adjusting rod. The left end of the adjusting rod is placed on the right side of the limit stopper, and a reverse driving force is generated to push the moving platform to move, so as to adjust the track gap between the rails of the moving platform and the rails of the fixed track bed. It is more convenient and time-saving to adjust the track gap in this way, and it is avoided that the rails are exposed to the sun and expand due to heat, resulting in the reduction of the track gap, causing the collision between the rails of the moving platform and the rails of the fixed track bed, and affecting the safe operation of the equipment.

[0013] 2. When the utility model adjusts the track gap between the steel rail of the moving platform and the fixed steel rail of the fixed track bed, the scale lines and digital markings on the outer wall of the adjustment rod are arranged to facilitate the staff to observe the track gap between the steel rail of the moving platform and the fixed steel rail, and prevent the adjusted track gap from being greater than or less than the standard value.
