[0002] Train maintenance usually needs to be carried out when the train stops for a short time, and the maintenance equipment must be able to be quickly disassembled and assembled so that the maintenance work can be completed in a short time. However, the existing train maintenance equipment has the following main problems: 1. Disassembly and installation of components is time-consuming and labor-intensive, which reduces the maintenance efficiency; 2. Tools are required for disassembly and assembly, which increases the complexity of operation; 3. The problem of loose connection is prone to occur during the disassembly and assembly process, which affects the maintenance quality; 4. The train stop time is limited, and the maintenance work needs to be completed in a short time. Therefore, a train maintenance device that can be quickly disassembled and assembled is needed to improve the maintenance efficiency and reduce costs. Utility Model Content

[0003] The utility model aims to provide a train maintenance device with a quick connection device, which can simplify the disassembly and assembly process, improve the maintenance efficiency and reduce the maintenance cost.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A train maintenance device comprises a base, a support frame and a workbench connected in sequence from bottom to top, wherein the support frame comprises two main rods and a plurality of cross rods connected to the main rods, and one end of the main rod is connected to the base through a quick disassembly mechanism;

[0006] The workbench has four vertical rods, which are respectively connected to the other end of the main rod through quick-release nuts; each of the vertical rods is provided with a plurality of bosses, and the other end of the main rod is provided with a connecting portion, and the clamping portion of the quick-release nut is pressed against the connecting portion; a through hole is provided on the connecting portion, and the through hole can be adapted to the boss.

[0007] Preferably, the quick-release nut further comprises: a screwing portion fixedly connected to the pressing portion, and a fastening portion coaxially arranged with the pressing portion.

[0008] Preferably, the clamping portion is in a sleeve shape, and its inner diameter is slightly larger than that of the boss.

[0009] Preferably, there are two support frames, and a plurality of support connecting rods are provided between the two support frames. Both ends of the support connecting rods are provided with quick-release buckles, so that the support connecting rods and the cross bar can be quickly connected.

[0010] Preferably, the quick disassembly and assembly mechanism comprises: a first clamp fixedly connected to one end of the main rod, and a second clamp rotatably connected to the first clamp, and the first clamp and the second clamp are fastened to the base via fasteners.

[0011] Preferably, the main rod comprises a plurality of tube sections, and every two tube sections are connected by a conical pin. To prevent the conical pin from falling off, a spring pin is also provided at the small end of the conical pin.

[0012] Preferably, the other tubes in the multi-section tube except the first section and the tail section have a male end and a female end, the opening portion of the female end is provided with a flare, the male end has a step portion, the step portion is axially abutted against the opening portion of the female end, and the step portion has a first conical surface, which cooperates with the flare to obtain a stable connection.

[0013] Preferably, a second conical surface is provided on the top of the male end to facilitate the docking of the male end of the tube in the front section with the female end of the tube in the rear section.

[0014] One end of the first section tube and the tail section tube may be provided with a female end or a male end to facilitate connection with the male end or the female end of the other end tube. It is understandable that, as a technician in this field should know, in order to obtain a sufficiently long rod, a splicing arrangement of multiple tubes is adopted.

[0015] Preferably, a plurality of insulating wheels are arranged on the base, and a limiting portion for preventing rotation is arranged on the insulating wheel.

[0016] Preferably, a limit device for preventing the insulating wheel from rotating is provided on the base, and the limit device includes a pin, and the pin cooperates with the limit part; when the insulating wheel needs to stop rotating, the pin only needs to be inserted into the limit part to prevent the insulating wheel from rotating, thereby improving the stability of the train maintenance device and reducing the risk of operators working at heights.

[0017] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0018] (1) The train maintenance device of the utility model cooperates with the boss on the vertical rod through the through hole of the connecting part on the main rod, and the pressing part on the quick-release nut only presses the connecting part tightly in the axial direction, which cleverly solves the problem that the fastening part of the existing quick-release nut is easily not tightened due to the radial force and the quick-release nut is easily damaged during the fastening process, and the service life of the quick-release nut is extended, and the disassembly and assembly efficiency is improved.

[0019] (2) The train maintenance device of the utility model is provided with a quick disassembly and assembly mechanism so that the support frame and the base can be disassembled and assembled by simply twisting the fasteners by hand, which is convenient and quick without the need for additional tools.

[0020] (3) The train maintenance device of the present invention uses a support connecting rod with a quick-release buckle. In order to ensure the stability of the two support frames, it is only necessary to clamp the block buckles at both ends of the support connecting rod on the cross bars of the support frames respectively. This not only improves the stability and convenience of the train maintenance device, but also saves the installation time of the entire train maintenance device.

[0021] (4) In the train maintenance device of the utility model, the main rod of the support frame is formed by quickly connecting multiple short tubes. The conical pin, the male end and the female end and their specific structure are set to improve the concentricity of the connection, solve the problem of the existing multi-tube connecting rod easily generating gaps and shaking, and further improve the convenience of the transportation process.

[0022] (5) In the train maintenance device of the present invention, the insulating wheel can be limited by a limiting device. When the pin of the limiting device is inserted into the limiting part of the insulating wheel, the insulating wheel can be prevented from rotating, thereby improving the stability of the train maintenance device and reducing the risk of operators working at heights.

[0023] (6) The various components of the train maintenance device of the present invention are mostly made of aluminum alloy, which is not only rust-proof but also lightweight, thereby improving the service life and convenience of the entire device.

[0024] In summary, the train maintenance device of the present invention does not require any other auxiliary tools during the entire disassembly and assembly process, which simplifies the disassembly and assembly process, improves maintenance efficiency, and reduces maintenance costs.
