Description

Technical Field

[0001] The present invention relates to the field of rail vehicles, and in particular to a high-torque 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 6 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 high-torque disassembly and assembly tool for disassembling and assembling the vehicle-end connector of railway passenger cars. Summary of the Invention

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

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is: A high-torque 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; a power module, which is arranged in the disassembly and assembly component and independently drives each sleeve in the sleeve group, and the power module achieves high-torque rotation of the fixing bolts through a hammering structure.

[0006] By providing a disassembly and assembly component, the disassembly and assembly component has a sleeve group with the same array as the fixing bolts on the railway passenger car car-end connector, and each sleeve is independently driven to rotate by a power module. 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 individually one by one, which is faster and more efficient. In addition, by providing a power module with a hammer structure, a greater torque output can be achieved.

[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 driving motor, a reducer, a compression spring, a striking block, a struck T-shaped shaft and a power casing; the driving motor, the reducer, the compression spring, the striking block and the struck T-shaped shaft are all integrated in the power casing, and the power casing is split in half, the input end of the reducer is fixedly connected to the output shaft of the driving motor, the striking block is slidingly connected to the output shaft of the reducer, and the compression spring is passed through the output shaft of the reducer. When the striking block is located at the end of the output shaft of the reducer, the compression spring is in a pre-tightened state, and the struck T-shaped shaft is engaged with the striking block when the striking block is located at the end of the output shaft of the reducer, and the end passes through the power casing.

[0010] The power casing is set to be split in half for easy installation. The driving motor outputs power to the reducer, the reducer increases the torque, and then outputs it to the striking block, driving the striking block to rotate. The convex teeth on the striking block engage with the struck T-shaft, driving the struck T-shaft to rotate. When the fixing bolt is tightened and a larger torque is required, it will cause resistance to the rotation of the striking block. The resistance will cause the striking block to compress the compression spring and retract, disengaging from the struck T-shaft. Since the compression spring will rebound, the next convex tooth of the striking block will engage with the struck T-shaft, forming an impact rotation, and realizing the tightening of the fixing bolt. The power of the driving motor can be adjusted to adjust the striking frequency of the striking block on the struck T-shaft, thereby adjusting the output torque. It can be adjusted during use, and the torque adjustment flexibility is better.

[0011] 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 end of the struck T-shaped shaft; the power housing here is vertically arranged on the second partition plate, and the struck T-shaped shaft passes through 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 end of the impact T-shaped shaft located at the tail of the teardrop-shaped array. The power casing here is vertically arranged on the first partition, and the impact T-shaped shaft located at the tail of the teardrop-shaped array passes through the first partition. The bottom end of the universal joint passes through the second partition and is rotatably connected to the second partition.

[0012] 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.

[0013] It is further defined that a horizontal operating handle is provided on the second partition, and the operating handle extends out of the side panel of the shell; by providing the operating handle on the second partition and extending the operating handle out of the side panel, the device can be easily operated.

[0014] 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.

[0015] It is further defined that a cooling fan is embedded in the side panel of the shell; by providing the cooling fan, the driving motor and rotating parts inside the shell can be cooled to ensure the performance of the disassembly and assembly components.

[0016] 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 gear position of the drive motor; the motor forward and reverse switch and the switch for controlling the gear position of the drive motor are respectively provided on the main handle and the sub-handle, and by providing the switch for controlling the gear position of the drive motor, real-time adjustment of the output torque can be achieved, which makes it easier to disassemble and assemble the fixing bolts.
