Description

Technical Field

[0001] The utility model relates to the technical field of coupler connection detection, and more specifically, it relates to a coupler functional test bench. Background Technique

[0002] A coupler refers to the hook at both ends of a train car body or locomotive, which has the functions of connection, traction and buffering. A coupler is a vehicle component used to connect locomotives and vehicles or between vehicles, transmit traction force and impact force, and keep a certain distance between vehicles.

[0003] At present, the forces acting on the coupler during train operation are relatively complex, including alternating traction force, random compression force and impact force. Especially during shunting operations, the coupler has to bear a very large impact force. Therefore, the coupler is a vulnerable part and is prone to failures such as deformation and wear. So after production and assembly and after maintenance, in order to test the product performance, a coupling test is required.

[0004] In the prior art, the Chinese utility model patent with the application number CN201820813239.4 discloses a coupler connection test bench, including a bottom plate. A rectangular groove is opened at the top of the bottom plate. At one end of the top of the bottom plate, fixed rods symmetrically arranged and arranged along the length direction of the bottom plate are installed. The fixed rods are distributed on both sides of the groove. A support plate is slidably connected to the top of the two fixed rods. Symmetrically arranged first mounting plates are slidably connected to the top of the support plate. A fixing plate is welded on the side of the two first mounting plates close to each other. A coupler body is installed on one side of the fixing plate along the horizontal direction. At the other end of the top of the bottom plate, a mounting seat is welded. Symmetrically arranged sliding plates are welded on the top of the mounting seat. Symmetrically arranged second mounting plates are slidably connected to the top of the sliding plates. With the cooperation of each component, the docking experiment between two couplers can be quickly carried out.

[0005] However, in the prior art, when installing the coupler body on the test bench, since the coupler body is heavy, it is necessary to lift the coupler by multiple people to complete the installation and disassembly of the coupler on the test bench, which wastes a lot of manpower and is prone to danger.

One of the two mounting seats 3 is fixed on the top of the frame base 1, and the other is fixed on the top of the moving mechanism. The two hooked parts of the coupler body are respectively fixed on the sides of the two mounting seats 3 close to each other. The gantry 4 is erected on the top of the frame base 1 and can slide along the length direction of the frame base 1 on the top of the frame base 1. A lifting seat 5 that can slide up and down on the gantry 4 is arranged on the gantry 4. The lifting seat 5 is located above the frame base 1 and between the two mounting seats 3. The suspension rod 51 is arranged in a U shape and is fixedly connected to the lifting seat 5. The coupler body is hooked in the U-shaped opening of the suspension rod 51.

[0031] The coupler body is suspended and lifted by the suspension rod 51, thus saving manpower and improving safety when the coupler body is installed and disassembled. When the two parts of the coupler body are respectively installed on the two mounting seats 3, first, the gantry 4 slides to make the gantry 4 close to one of the mounting seats 3, and then the gantry 4 assists in completing the installation of one part of the coupler body. After that, the gantry 4 slides to the other mounting seat 3 to assist in completing the installation of the other part of the coupler body.

[0032] Specifically, the gantry 4 includes a support rod 41 and a cross bar 42. There are two support rods 41 and they are vertically arranged. The two support rods 41 are respectively arranged on both sides of the frame base 1 and can slide along the length direction of the frame base 1 on both sides of the frame base 1. The two ends of the cross bar 42 are respectively fixedly connected to the tops of the two support rods 41. The lifting seat 5 is arranged below the cross bar 42.

[0033] Specifically, the frame base 1 includes two I-beams 11 arranged along the length direction of the frame base 1 and end rods 12 arranged at both ends of the two I-beams 11. The two ends of the end rods 12 are respectively fixedly connected to the two ends of the I-beams 11.

[0034] The I-beam 11 includes a vertical plate 111 and two flat plates 112 fixedly connected to the top and bottom of the I-beam 11. The two flat plates 112 form two sliding grooves on both sides of the I-beam 11. A set of rollers 43 are rotatably connected to the sides of the two support rods 41 of the gantry 4 close to each other. The rollers 43 of the same set are embedded in the sliding grooves on the two sides of the two I-beams 11 away from each other. Among the multiple rollers 43 of the same set, at least two rollers 43 are in contact with the flat plate 112 at the top of the sliding groove, and at least two rollers 43 are in contact with the flat plate 112 at the bottom of the sliding groove.

[0035] The moving mechanism includes a sliding seat 2, which is arranged between two I-beams 11. The mounting seat 3 fixed to the top of the moving mechanism is fixedly connected to the top of the sliding seat 2. The moving mechanism further includes two groups of moving wheels 21 respectively rotatably connected to both sides of the sliding seat 2. The two groups of moving wheels 21 are respectively located in the two sliding grooves on the two sides of the two I-beams 11 close to each other.

[0036] Specifically, a cylinder for driving the sliding seat 2 to slide is fixedly connected to the frame base 1.

[0037] Specifically, this embodiment further includes a clamping device. The clamping device includes two clamping blocks 6, which are arranged between two support rods 41 and can slide in the directions of approaching and separating from each other. When the suspension rod 51 drives the coupler body upward to align with the mounting seat 3 in height, the two clamping blocks 6 slide towards each other to clamp the coupler body.

[0038] V-shaped grooves 61 are provided on the sides of the two clamping blocks 6 close to each other. The two V-shaped grooves 61 open towards the side close to each other, and the groove walls of the V-shaped grooves 61 are parallel to the length direction of the frame base 1. The clamping device further includes clamping wheels 62. Clamping wheels 62 are provided on the two groove walls of the V-shaped groove 61. The axis of the clamping wheel 62 is parallel to the groove wall of the V-shaped groove 61 where the clamping wheel 62 is arranged and perpendicular to the length direction of the frame base 1. A mounting seat 3 is fixedly connected to the groove wall of the V-shaped groove 61, and the clamping wheel 62 is rotatably connected to the mounting seat 3.
