Description

Technical Field

[0001] This utility model belongs to the field of bolt disassembly and assembly technology, and relates to a high-efficiency train bottom bolt disassembly and assembly device. Background Technology

[0002] A train is a modern land transportation vehicle consisting of multiple carriages or train sets connected together and running on tracks. Its core functions focus on passenger commuting, freight transport, and cross-regional material flow. It is an indispensable key component of the transportation system and encompasses various types, including conventional trains suitable for short and medium-distance travel, high-speed trains and bullet trains that meet the needs of efficient commuting, and freight trains that undertake the task of transporting bulk materials. It can flexibly adapt to the needs of different transportation scenarios. The stable operation of a train depends on a complete core system and components. The traction system (such as locomotives and power carriages) provides the driving power, and with the coordinated work of key components such as bogies, braking systems, and underframes, it achieves smooth and safe track travel, becoming an important carrier for the flow of people and goods in modern society.

[0003] The numerous bolts on the bottom of the train are core connecting components that ensure its safe operation. They are responsible for fixing and connecting key components, especially for stabilizing core connection points such as the bogie and car body, and the braking system and underframe. The reliability of these connections directly determines the safety and stability of train operation. Whether it is checking the condition of bolts during routine maintenance, or disassembling and assembling bolts during troubleshooting and regular overhauls, these are all critical aspects of train operation and maintenance. The installation quality, tightening accuracy, and anti-loosening effect of these bolts directly affect the stability of the train under high-speed, long-distance, and complex road conditions. Once bolts become loose, fall off, or are not tightened properly, it may cause serious safety hazards. Therefore, bolt-related operation and maintenance work is always of paramount importance to train safety.

[0004] However, the industry still largely relies on manual labor to install bolts at the bottom of trains. Workers have to crawl into the narrow, dark, and poorly ventilated space under the train, bending over or lying down to work. They not only have to rely on experience to align the bolt holes, but also manually operate a wrench to apply torque. Under such high-intensity labor, fatigue errors are likely to occur, leading to problems such as uneven bolt tightening torque and installation position deviations. At the same time, the disassembly and assembly of a single bolt takes a long time, resulting in low overall work efficiency and making it difficult to meet the industry's needs for high-frequency maintenance and rapid operation and maintenance in railway transportation. Utility Model Content

[0005] The technical problem this utility model aims to solve is that the industry still generally relies on manual labor to install bolts at the bottom of trains. Workers need to crawl into the narrow, dark, and poorly ventilated bottom of the train, bending over or lying down to work. They not only need to rely on experience to align the bolt holes, but also need to manually operate a wrench to apply torque. Under high-intensity labor, fatigue errors are prone to occur, resulting in problems such as uneven bolt tightening torque and installation position deviation. At the same time, the disassembly and assembly of a single bolt takes a long time, and the overall work efficiency is low, which is difficult to adapt to the industry needs of high-frequency inspection and rapid operation and maintenance in railway transportation.

[0006] This utility model discloses a high-efficiency train bottom bolt removal and installation device, comprising a support frame, a movable platform mounted on the upper end of the support frame, two two-phase stepper motors mounted on the upper end of the movable platform, a linear guide slide mounted on the upper end of each two-phase stepper motor, fixed rods symmetrically fixedly connected to the upper end of the movable platform, and anti-rotation grooves formed at opposite ends of the two fixed rods, sliders mounted on the outer side of the linear guide slides, the sliders being slidably connected to the fixed rods, a servo motor disposed between the two sliders, and an embedded block symmetrically fixedly connected to the outer side of each servo motor, the embedded block being threadedly connected to the slider by bolts, support blocks fixedly connected to the four corners of the support frame, a moving component disposed between the support frame and the movable platform, and a lifting mechanism symmetrically mounted at the ends of the support frame.

[0007] The moving component includes a first slide bar. Two first slide bars are provided at the upper end of the support frame. Connecting blocks are fixedly connected to both ends of the first slide bars. The connecting blocks are fixedly connected to the support frame. Two first fixing blocks are fixedly connected to the lower end of the moving platform. A sliding sleeve is fixedly connected to the inner side of the first fixing block. The first slide bar is located inside the sliding sleeve and is slidably connected to the sliding sleeve.

[0008] The lifting mechanism includes a fixed frame, and two fixed frames are symmetrically fixedly connected to the end of the support frame. Fixed plates are fixedly connected to the upper ends of the two fixed frames, and electric push rods are symmetrically installed at the lower ends of the fixed plates. Lifting frames are fixedly connected to the telescopic ends of the two electric push rods. Wheels are installed at opposite ends of the two lifting frames. A stabilizing component is also provided between the fixed frame and the lifting frame.

[0009] The stabilizing component includes a connecting plate. The connecting plate is symmetrically and fixedly connected to one end of the lifting frame near the fixed frame. A second sliding rod is fixedly connected to the end of the connecting plate away from the wheel. A sliding cylinder is fixedly connected to the inner side of the fixed frame. The second sliding rod is located inside the sliding cylinder and is slidably connected to the sliding cylinder.

[0010] The mobile platform has a limiting groove at one end corner, and the support frame has a positioning groove in the middle. The limiting groove and the positioning groove are slidably connected by a positioning pin.

[0011] A second fixing block is fixedly connected to the end of the support frame, and a connecting rod is rotatably connected to the inner side of the second fixing block. A seat is fixedly connected to the end of the connecting rod away from the second fixing block.

[0012] A cable housing is fixedly connected to the outside of the servo motor, and a control handle is fixedly connected to the end of the cable housing.

[0013] A light pole is installed at one end of the cable housing, and a rotating light is installed at the end of the light pole away from the cable housing.

[0014] The upper end of the mobile platform is symmetrically equipped with a reversing pedal and a forward rotating pedal.

[0015] The upper end of the support frame is fixedly connected to the battery casing, and the inner side of the reversing pedal is equipped with the battery body.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: by controlling the forward and reverse rotation of the two-phase stepper motor through the reverse pedal and the forward pedal, the linear guide slide table is driven to move the slider to complete the height adjustment, so that the bolt sleeve can quickly fit the bolt. Then, the control handle controls the forward and reverse rotation of the servo motor to drive the sleeve to rotate, thereby completing the installation and removal of the bolt. This greatly reduces the labor intensity of the staff, avoids the risk of working in narrow spaces, and effectively reduces the problems of bolt loosening and stripping caused by human operation errors, providing a safe, efficient and stable solution for the maintenance of bolts at the bottom of the train.

[0017] By activating the electric push rod, the lifting frame moves downward, causing the two wheels to quickly touch the ground and form support. The reaction force then lifts the entire support frame, preventing the support frame and support block from directly contacting the ground. This significantly reduces frictional resistance when the device moves, making it easier and more convenient for workers to push the device and effectively improving the efficiency of transferring the equipment within the work area.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1 like Figure 1 - Figure 5As shown, a high-efficiency train bottom bolt removal and installation device includes a support frame 101. A moving platform 102 is mounted on the upper end of the support frame 101. Two two-phase stepper motors 103 are mounted on the upper end of the moving platform 102. A linear guide slide 104 is mounted on the upper end of each two-phase stepper motor 103. Fixed rods 105 are symmetrically fixedly connected to the upper end of the moving platform 102. Anti-rotation grooves 106 are opened on opposite ends of the two fixed rods 105. A slider 107 is mounted on the outer side of the linear guide slide 104. The slider 107 is slidably connected to the fixed rods 105. The slider 107 is limited by the fixing rod 105 and the anti-rotation groove 106, making the slider 107 more stable when lifting and lowering. A servo motor 108 is provided between the two sliders 107. Embedded blocks 109 are symmetrically fixedly connected to the outside of the servo motor 108. The embedded blocks 109 and the sliders 107 are threadedly connected by bolts. Support blocks 110 are fixedly connected to the four corners of the support frame 101. A moving component is provided between the support frame 101 and the moving platform 102. Lifting mechanisms are symmetrically installed at the ends of the support frame 101.

[0025] A second fixing block 601 is fixedly connected to the end of the support frame 101. A connecting rod 602 is rotatably connected to the inner side of the second fixing block 601. A seat 603 is fixedly connected to the end of the connecting rod 602 away from the second fixing block 601. To control the forward and reverse rotation of the servo motor 108, a cable housing 701 is fixedly connected to the outer side of the servo motor 108. A control handle 702 is fixedly connected to the end of the cable housing 701. A light pole 80 is installed at the end of the cable housing 701 for the operator to use. 1. A rotating light 802 is installed at the end of the light pole 801 away from the cable housing 701; in order to enable the operator to control the rotation of the two-phase stepper motor 103 at both ends of the moving platform 102, a reverse pedal 901 and a forward pedal 902 are symmetrically installed at the upper end of the moving platform 102; in order to provide power to the device, a battery housing 951 is fixedly connected to the upper end of the support frame 101, and a battery body 952 is installed on the inner side of the reverse pedal 901.

[0026] During operation, the operator moves the support frame 101 to the designated area using the lifting assembly, then installs the designated bolt sleeve on the upper end of the servo motor 108. The battery body 952 is then activated to provide power to the device. The two two-phase stepper motors 103 are controlled to rotate in both directions via the reverse pedal 901 and the forward pedal 902. These two-phase stepper motors 103 drive the linear guide slide 104, which in turn moves the slider 107 to a suitable height, allowing the bolt sleeve to engage the bolt. The servo motor 108 is then controlled to rotate in both directions via the control handle 702, causing the servo motor 108 to rotate the bolt sleeve, thus allowing for the installation and removal of the bolt.

[0027] Example 2 like Figure 1 - Figure 4 As shown, the lifting mechanism includes a fixed frame 301. Two fixed frames 301 are symmetrically fixedly connected to the end of the support frame 101. Fixed plates 302 are fixedly connected to the upper ends of the two fixed frames 301. Electric push rods 303 are symmetrically installed at the lower ends of the fixed plates 302. Lifting frames 304 are fixedly connected to the telescopic ends of the two electric push rods 303. Wheels 305 are installed on opposite ends of the two lifting frames 304.

[0028] To make the lifting frame 304 more stable when moving, a stabilizing component is also provided between the fixed frame 301 and the lifting frame 304. The stabilizing component includes a connecting plate 401. The connecting plate 401 is symmetrically fixedly connected to one end of the lifting frame 304 near the fixed frame 301. A second sliding rod 402 is fixedly connected to one end of the connecting plate 401 away from the wheel 305. A sliding cylinder 403 is fixedly connected to the inner side of the fixed frame 301. The second sliding rod 402 is located inside the sliding cylinder 403 and is slidably connected to the sliding cylinder 403.

[0029] When the operator needs to move the device, the electric push rod 303 is activated, which causes the telescopic end of the electric push rod 303 to move the lifting frame 304 downward, thereby causing the two wheels 305 to contact the ground. After the two wheels 305 contact the ground, the reaction force causes the support frame 101 to rise, thereby preventing the support frame 101 and the support block 110 from contacting the ground, making it more convenient for the operator to move the support frame 101. When the lifting frame 304 is raised or lowered, it slides on the inside of the slide cylinder 403 via the second slide rod 402, thereby making the movement of the lifting frame 304 more stable.

[0030] Example 3 like Figure 1 - Figure 5As shown, a moving component is provided between the support frame 101 and the moving platform 102; the moving component includes a first slide rod 201, and two first slide rods 201 are provided at the upper end of the support frame 101. Both ends of the first slide rod 201 are fixedly connected to a connecting block 202, and the connecting block 202 is fixedly connected to the support frame 101. Two first fixing blocks 203 are fixedly connected at the lower end of the moving platform 102. A sliding sleeve 204 is fixedly connected to the inner side of the first fixing block 203, and the first slide rod 201 is located inside the sliding sleeve 204 and is slidably connected to the sliding sleeve 204.

[0031] The mobile platform 102 has a limiting groove 501 at one end corner, and the support frame 101 has a positioning groove 502 in the middle. The limiting groove 501 and the positioning groove 502 are slidably connected by a positioning pin 503.

[0032] During operation, the positioning pin 503 is pulled out from the inside of the positioning groove 502 and the limiting groove 501. Then, the operator can move the mobile platform 102 to a convenient installation area. Specifically, the operator pulls the mobile platform 102, causing the mobile platform 102 to move the first fixed block 203 and the sliding sleeve 204 to the outside of the first sliding rod 201. Then, the bolt sleeve is installed on the upper end of the servo motor 108. Then, the mobile platform 102 is pushed back to its original position, and the positioning pin 503 is inserted into the inside of the limiting groove 501 and the positioning groove 502.

These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it.
