Description

Technical Field

[0001] The present invention relates to the field of rail vehicles, and in particular to a disassembly and assembly tool for disassembling and assembling a vehicle-end connector of a railway passenger vehicle. Background Art

[0002] The railway passenger car end connector is one of the important devices for connecting cars. During routine maintenance, it is necessary to remove all the fixing bolts before installing. Figure 4 As shown, it is in the shape of a water drop, and 10 fixing bolts are arranged on the edge ring. At present, the installation method for the vehicle-end connector of railway passenger cars is that workers use handheld electric tools to install, tighten or remove the 10 fixing bolts of the connector one by one. However, this method is not only labor-intensive, but also slow in installation speed and low in labor efficiency.

[0003] To this end, we propose a disassembly and assembly tool for disassembling and assembling a vehicle-end connector of a railway passenger car. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a disassembly and assembly tool for disassembling and assembling a vehicle-end connector of a railway passenger car.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is: A disassembly and assembly tool for disassembling and assembling a railway passenger car vehicle-end connector comprises: a disassembly and assembly component, comprising a sleeve group arranged at the bottom thereof, wherein the sleeves in the sleeve group and the fixing bolts on the railway passenger car vehicle-end connector are arranged in the same teardrop-shaped array; and a power module, arranged in the disassembly and assembly component, for independently rotating and driving each sleeve in the sleeve group.

[0006] By setting up a disassembly and assembly component, which has a sleeve group with the same array as the fixing bolts on the railway passenger car car-end connector, and using a power module to independently drive the rotation of each sleeve, the disassembly and assembly component can be aligned with the fixing bolts on the railway passenger car car-end connector, and all the fixing bolts on the railway passenger car car-end connector can be disassembled and assembled at the same time, without the need to disassemble and assemble them one by one, which is faster.

[0007] It is further defined that the disassembly and assembly component also includes a shell, a first partition, a second partition and a transmission assembly; the shell includes a top plate, a bottom plate, a side plate and a skeleton rod connecting the top plate and the bottom plate, the first partition and the second partition are arranged on the skeleton rod in sequence from top to bottom, dividing the shell into three independent spaces, the power module located at the tail of the teardrop-shaped array is arranged on the first partition, and the remaining power modules are arranged on the second partition, the transmission assembly passes through the first partition and the second partition, and the two ends are respectively connected between the power module and the sleeve group.

[0008] Since the spacing between the fixing bolts at the rear end of the railway passenger car connector is too small, the power module corresponding to the fixing bolts at the rear end of the railway passenger car connector cannot be installed in the same way as its head due to volume issues. A first partition and a second partition are set, and the power module corresponding to the rear end is installed on the higher first partition, which can provide a larger installation space for the transmission component and achieve a more reasonable installation.

[0009] It is further defined that the power module includes a drive motor and a reducer; the shell of the reducer is a cylindrical shape with a closed top, the drive motor is vertically arranged at the top of the reducer shell, and the output shaft extends into the reducer, and the output shaft of the drive motor is transmission-connected to the input end of the reducer; by arranging a reducer at the output end of the drive motor, the output torque of the drive motor is increased, the output speed of the drive motor is reduced, and the fixing bolts are more convenient to disassemble and assemble.

[0010] It is further defined that the transmission assembly located outside the tail of the teardrop-shaped array includes a telescopic shaft cylinder, a telescopic shaft rod, a return spring and a conversion head; the bottom end of the conversion head is connected to the tail of the sleeve in the sleeve group, and the top end is fixedly connected to the bottom end of the telescopic shaft rod; the bottom plate of the shell is provided with a through hole for the conversion head to pass through; the telescopic shaft rod is slidably arranged in the telescopic shaft cylinder, and the return spring is arranged on the telescopic shaft rod outside the telescopic shaft cylinder; when the telescopic shaft rod is at the maximum extension length, the return spring is in a pre-tightened state, and the top end of the telescopic shaft cylinder is fixedly connected to the output shaft of the reducer; the top of the shell of the drive motor here passes through the first partition plate, and the output shaft end of the reducer passes through the second partition plate and is rotatably connected to the second partition plate; The transmission assembly located at the tail of the teardrop-shaped array also includes a universal joint. The top end of the telescopic shaft located at the tail of the teardrop-shaped array is fixedly connected to the bottom end of the universal joint. The top end of the universal joint is fixedly connected to the output shaft end of the reducer located at the tail of the teardrop-shaped array. The bottom of the reducer housing here is fixed on the first partition. The output shaft end of the reducer located at the tail of the teardrop-shaped array passes through the first partition and is rotatably connected to the first partition. The bottom end of the universal joint passes through the second partition and is rotatably connected to the second partition.

[0011] The sleeve of the sleeve group and the telescopic shaft are connected through the conversion head. When the device presses the sleeve down to combine with the fixing bolt on the railway passenger car car-end connector, the power module can be started to drive the telescopic shaft cylinder to rotate, the telescopic shaft cylinder drives the telescopic shaft rod to rotate, the telescopic shaft rod drives the conversion head to rotate, and the conversion head drives the sleeve to rotate. When the sleeve encounters resistance in contact with the fixing bolt, the telescopic shaft rod will be compressed into the telescopic shaft cylinder. During the rotation of the sleeve, due to the rebound of the return spring outside the telescopic shaft rod, the sleeve will be combined with the fixing bolt. A universal joint is added to the tail of the railway passenger car car-end connector, that is, the top of the telescopic shaft cylinder of the transmission assembly at the tail of the teardrop-shaped array to realize power steering and connect with the drive motor on the first compartment, providing a better installation layout for the two drive motors on the first compartment, and avoiding the problem that the two drive motors on the first compartment cannot be reasonably installed.

[0012] It is further defined that an operating handle is horizontally provided on the side panel of the shell; by providing the operating handle on the side panel of the shell, it is convenient to operate the device.

[0013] It is further defined that a number of positioning panels are vertically provided on the bottom plate of the shell, the inner diameter of the space enclosed by the number of positioning panels is loosely matched with the outer diameter of the railway passenger car car-end connector, and is staggered with the sleeves in the sleeve group; positioning panels matching the outer diameter of the railway passenger car car-end connector are provided on the bottom plate of the shell, which facilitates positioning between the disassembly and assembly components and the railway passenger car car-end connector, making disassembly and assembly more convenient.

[0014] It is further defined that the operating handle includes a main handle and a sub-handle, and the main handle and the sub-handle are respectively provided with a switch for controlling the forward and reverse rotation of the drive motor and a switch for controlling the power on and off of the drive motor; the forward and reverse rotation switch of the motor and the switch for controlling the power on and off of the drive motor are respectively provided on the main handle and the sub-handle, which is more convenient for operation.

[0015] The beneficial effect of the present invention is that by providing a disassembly and assembly component with the same array as the fixing bolts on the railway passenger car vehicle-end connector, the fixing bolts on the railway passenger car vehicle-end connector can be disassembled and assembled at the same time, without having to disassemble and assemble them one by one, thus saving manpower and improving disassembly and assembly efficiency.
