Description

Technical Field

[0001] This utility model relates to the field of bogie tilting technology, and in particular to a railway freight car bogie tilting platform. Background Technology

[0002] The railway freight car bogie is a key component of railway freight cars and the main load-bearing structure of railway freight cars. It directly affects the running quality of railway freight cars. In order to ensure the safe operation of railway freight cars, the bogie needs to be inspected and maintained regularly. During the inspection and maintenance process, a tilting platform is used to tilt the bogie multiple times.

[0003] Existing technologies, such as Chinese Patent Publication No. CN222060284U, disclose a bogie draining and tilting device, including a pair of symmetrically arranged tilting devices, with each side of the bogie connected to one of the tilting devices; it includes a mechanical slide, a column assembly mounted on the mechanical slide, a tilting assembly mounted on the column assembly, and a clamping assembly mounted on the tilting assembly; the mechanical slide has a sliding pair, and the column assembly is mounted on the slider of the sliding pair and is movable in the horizontal direction; the tilting assembly includes a tilting element and a second driving element that drives the tilting element to rotate around a horizontal axis, the tilting element and the second driving element are mounted on a support, and the support is mounted on the column assembly; the tilting element has a support platform, and the clamping assembly is mounted on the support platform; it also includes a support assembly mounted on the tilting element, forming a clamping gap between the support assembly and the clamping assembly. This utility model has high safety and improves the stability of bogie rotation and draining. However, this utility model fixes the support assembly, resulting in it only being able to clamp and position bogies of a single specification, thus lacking applicability.

[0004] To address the issue that railway freight car bogie tilting platforms are not convenient for clamping and securing bogies of different specifications during tilting, most existing equipment only positions bogies of a single specification, which is not versatile enough. This means that when tilting bogies of different specifications, it may be necessary to use tilting and positioning equipment of the corresponding specification, making the process time-consuming and labor-intensive. Therefore, improvements are needed. Summary of the Invention

[0005] The purpose of this utility model is to solve the problem that existing railway freight car bogie tilting platforms are not convenient for clamping and fixing bogies of different specifications during tilting, and to propose a railway freight car bogie tilting platform.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a railway freight car bogie tilting platform, comprising a slide rail, a slide table, a rotary cylinder, a rotary pump, a turntable, and a positioning mechanism, wherein the slide table is slidably disposed on the surface of the slide rail, the turntable is disposed on the surface of the slide table, and the positioning mechanism is disposed on the surface of the turntable;

[0007] The positioning mechanism includes an adjustment component, a drive component, and an auxiliary component. The adjustment component includes a bidirectional threaded rod, which is rotatably connected to the inner wall of the turntable. A movable frame is threadedly connected to the surface of the bidirectional threaded rod, and the movable frame is slidably connected to the inner wall of the turntable. There are two sets of movable frames arranged symmetrically, and a support column is fixedly connected to the surface of the movable frame.

[0008] The inner wall of the turntable is rotatably connected to a screw, and the surface of the screw is threadedly connected to a lifting frame. The lifting frame is slidably connected to the inner wall of the turntable, and a pressure table is fixedly connected to the surface of the lifting frame.

[0009] Furthermore, the drive assembly includes a motor, which is fixedly mounted on the surface of the turntable. A worm gear is fixedly connected to the output end of the motor, and the worm gear is rotatably connected to the inner wall of the turntable.

[0010] Furthermore, a worm gear is fixedly connected to the surface of the bidirectional threaded rod, and the worm gear is meshed with the surface of the worm.

[0011] Furthermore, a second motor is fixedly mounted on the surface of the turntable, and a second worm gear is fixedly connected to the output end of the second motor. The second worm gear is rotatably connected to the inner wall of the turntable. A second worm wheel is fixedly connected to the surface of the screw, and the second worm wheel meshes with the surface of the second worm gear.

[0012] Furthermore, the auxiliary component includes copper gaskets, and there are two sets of copper gaskets respectively disposed on the surfaces of the support column and the pressure table. The surfaces of the support column and the pressure table are provided with screw holes, and screws are threaded onto the surfaces of the screw holes.

[0014] Furthermore, the rotary cylinder is fixedly mounted on the surface of the slide table, the turntable is fixedly connected to the output end of the rotary cylinder, and the rotary pump is connected to the rotary cylinder through a hydraulic connector.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a positioning mechanism is set up. The motor is started to make the worm gear drive the worm wheel and the double-threaded rod to rotate, thereby making the two sets of movable frames move towards each other or away from each other. According to the specifications of the bogie, the two sets of support columns are moved to the appropriate position. Then the bogie is moved between the two sets of slides. By moving the slides on the slide rails, the two sets of turntables move towards each other and approach the bogie until the support column is inserted into the receiving part of the bogie. After it is in place, the motor is started to make the worm gear drive the worm wheel and the screw to rotate, thereby making the lifting frame drive the pressure table to press down on the clamping part of the bogie, thus realizing the positioning of the bogie. The self-locking function between the worm wheel and the worm gear, and between the worm wheel and the worm gear, ensures that the support column and the pressure table have sufficient stability. After the positioning is completed, the rotary pump and the rotary cylinder can be used to rotate the turntable to realize the stable rotation of the bogie. The detachable copper shims are set up to avoid damage to the bogie by the support columns and the pressure table, and to facilitate the replacement of worn copper shims at any time.

[0017] 2. In this utility model, by setting a positioning mechanism, the bogie is stably clamped by the support columns and the pressure table for flipping operations. The distance between the two sets of support columns is adjustable, and the height of the pressure table is adjustable to adapt to bogies of different specifications, thus effectively improving the applicability of the equipment.

[0026] The specific setup and function of its positioning mechanism 6 will be explained below.

[0027] In this embodiment: the positioning mechanism 6 includes an adjustment component 61, a drive component 62 and an auxiliary component 63. The adjustment component 61 includes a bidirectional threaded rod 611, which is rotatably connected to the inner wall of the turntable 5.

[0029] The effects achieved by the above components are as follows: the support column 613 is provided to facilitate insertion into the receiving part of the bogie and to achieve a supporting function; the pressure table 616 is provided to clamp and fix the bogie after pressing the clamping part of the bogie in conjunction with the support column 613; the double-threaded rod 611 and two sets of movable frames 612 are provided so that when the double-threaded rod 611 rotates, the two sets of movable frames 612 can move towards each other or away from each other, thereby adjusting the distance between the two sets of support columns 613 to adapt to the receiving parts of bogies of different specifications; the screw 614 and the lifting frame 615 are provided so that when the screw 614 rotates, the lifting frame 615 can move up and down, thereby causing the pressure table 616 to press down on the clamping part of the bogie.

[0030] Specifically, the drive assembly 62 includes a motor 621, which is fixedly mounted on the surface of the turntable 5. The output end of the motor 621 is fixedly connected to a worm gear 622, which is rotatably connected to the inner wall of the turntable 5.

[0031] The effect achieved by the above components is as follows: the motor 621 and worm gear 622 are set to cooperate with the worm wheel 623. When the motor 621 is started, the worm gear 622 can drive the worm wheel 623 and the double-threaded rod 611 to rotate.

[0032] Specifically, a worm gear 623 is fixedly connected to the surface of the bidirectional threaded rod 611, and the worm gear 623 is engaged with the surface of the worm 622.

[0033] The effect achieved by the above components is that the self-locking function of the worm gear 623 and the worm 622 can maintain sufficient stability for the two sets of support columns 613.

[0034] Specifically, a second motor 624 is fixedly mounted on the surface of the turntable 5, and a second worm gear 625 is fixedly connected to the output end of the second motor 624. The second worm gear 625 is rotatably connected to the inner wall of the turntable 5. A second worm wheel 626 is fixedly connected to the surface of the screw 614, and the second worm wheel 626 is meshed with the surface of the second worm gear 625.

[0035] The effect achieved by the above components is as follows: the motor 624, worm gear 625 and worm wheel 626 are set so that when the motor 624 is started, the worm gear 625 can drive the worm wheel 626 and the screw 614 to rotate, and the self-locking function of the worm gear 625 and the worm wheel 626 can make the pressure table 616 have sufficient stability.

[0036] Specifically, the auxiliary component 63 includes copper gaskets 631. There are two sets of copper gaskets 631, which are respectively disposed on the surfaces of the support column 613 and the pressure table 616. The surfaces of the support column 613 and the pressure table 616 are provided with screw holes 632, and screws 633 are threaded onto the surfaces of the screw holes 632.

[0037] The effects achieved by the above components are as follows: the copper gasket 631 is provided to avoid damage to the bogie caused by hard contact between the support column 613 and the pressure plate 616 and the bogie; the screw hole 632 and screw 633 are provided to facilitate the disassembly and assembly of the copper gasket 631, and the copper gasket 631 can be replaced after wear.

[0038] Specifically, the copper washer 631 has a mounting hole 634 on its surface, the screw 633 is inserted into the mounting hole 634 for connection, and the copper washer 631 has a relief groove 635 on its surface.

[0039] The effects achieved by the above components are as follows: the mounting hole 634 is provided so that the copper washer 631 can be fixed after the screw 633 is inserted into the mounting hole 634 and tightened with the screw hole 632; the relief groove 635 is provided so that the screw 633 will not protrude and thus avoid affecting the clamping and fixing of the bogie.

[0040] Specifically, the rotary cylinder 3 is fixedly installed on the surface of the slide table 2, the turntable 5 is fixedly connected to the output end of the rotary cylinder 3, and the rotary pump 4 is connected to the rotary cylinder 3 through a hydraulic connector.

[0041] The effect achieved by the above components is that after the bogie is fixed between the two sets of turntables 5 by the positioning mechanism 6, the turntable 5 can be stably rotated by the rotary pump 4 in conjunction with the rotary cylinder 3.

[0042] Working principle: By setting up the positioning mechanism 6, starting the motor 621 causes the worm gear 622 to drive the worm wheel 623 and the double-ended threaded rod 611 to rotate, thereby causing the two sets of movable frames 612 to move towards each other or away from each other. According to the specifications of the bogie, the two sets of support columns 613 are moved to the appropriate position. Then, the bogie is moved between the two sets of slides 2. By moving the slides 2 on the slide rail 1, the two sets of turntables 5 move towards each other and approach the bogie until the support column 613 is inserted into the receiving part of the bogie. After it is in place, starting the motor 624 causes the worm gear 625 to drive the worm wheel 626 and the screw 614 to rotate, thereby causing the bogie to lift... The lowering frame 615 drives the pressure table 616 to press down on the clamping part of the bogie, thereby achieving the positioning of the bogie. The self-locking function between worm gear 1 623 and worm 1 622, and worm gear 2 626 and worm 2 625 ensures sufficient stability for the support column 613 and the pressure table 616. After positioning, the rotary pump 4 and the rotary cylinder 3 can be used to rotate the turntable 5 to achieve stable rotation of the bogie. A detachable copper gasket 631 is provided to prevent damage to the bogie by the support column 613 and the pressure table 616, and to facilitate the replacement of worn copper gaskets 631 at any time.

[0043] By setting up a positioning mechanism 6, the bogie is stably clamped by support columns 613 and pressure table 616 for flipping operations. The distance between the two sets of support columns 613 is adjustable, and the height of the pressure table 616 is adjustable to accommodate bogies of different specifications, thus effectively improving the applicability of the equipment.
