Description

Technical Field

[0001] This utility model relates to the field of rail transit maintenance equipment technology, and in particular to a maintenance equipment for rail transit electromechanical systems. Background Technology

[0002] The rail transit system is a complex integrated system. Its core functions rely on the coordinated work of a large number of electromechanical equipment. During long-term operation, these electromechanical equipment will inevitably experience problems such as wear, aging, loosening, poor contact, or functional degradation. In order to ensure the safety and reliability of train operation, regular inspection and maintenance of rail transit electromechanical equipment is required.

[0003] Currently, the maintenance of rail transit electromechanical equipment usually relies on a variety of different tools and equipment. These tools and equipment are often stored separately, and are of various types and specifications. When maintenance personnel need to retrieve them, they often need to search back and forth, which not only increases the labor intensity but also occupies valuable working space.

[0004] Chinese Patent Publication No. CN214329818U discloses a maintenance device for rail transit electromechanical systems, including a base plate, a moving mechanism, a door, a housing, and partitions. In use, the base plate is first moved to the location requiring maintenance via the cooperation of the wheel seats and rollers of the moving mechanism. Then, a threaded shank is rotated within a threaded sleeve, causing a pressure block to press against the roller, thus fixing the roller and limiting the moving mechanism. The user then opens the door using a handle, allowing the housing to be opened. The user retrieves the necessary maintenance tools from the storage compartments separated by partitions. Carrying the tools, the user climbs the ladder to the outside of the horizontal plate, then opens the door to reach the top of the horizontal plate. A support rod provides auxiliary support to the ladder, preventing excessive swaying during the climb.

[0005] In the aforementioned patent, the method of manually climbing to move to the maintenance platform is quite cumbersome. It lacks a device for raising and lowering the maintenance platform, and maintenance work is often carried out at height. The operator's hand grip is limited, and many tools lack auxiliary support devices during maintenance, which may easily affect the maintenance efficiency of the workers. There is also a lack of a device for temporary storage of maintenance tools and parts, which may lead to these tools and parts being stored in a scattered manner, making them easy to lose. Moreover, spreading them out takes up a lot of space on the maintenance platform, which may affect the operator's normal maintenance work. Utility Model Content

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1

[0028] like Figure 1 As shown, a maintenance equipment for rail transit electromechanical systems includes a support platform 1. A lifting device body 2 is fixedly connected to the bottom of the support platform 1. A base plate 3 is fixedly connected to the bottom of the lifting device body 2. Lockable casters 4 are fixedly connected to the four corners of the bottom of the base plate 3. A clamping mechanism 5 is symmetrically installed on the right side of the top of the support platform 1. A storage mechanism 6 is symmetrically engaged on the left side of the outer surface of the support platform 1.

[0029] In this embodiment, the lifting equipment body 2 is lowered to a height sufficient for the worker to move to the top of the platform 101. The tools and parts required for maintenance are placed inside the storage frame 606 for temporary storage. Then, the storage mechanism 6 is installed and fixed by engaging the U-shaped buckle 601 with the upper part of the outer surface of the guardrail 102. The lamps or other maintenance tools used during maintenance are placed between the two clamps 517. The handle 514 is rotated, and the left clamp 512 and the screw 513 rotate threadedly. The right disc 519 rotates inside the rotating sleeve 518, thereby achieving the effect of moving the left clamp 512 to the left or right on the side of the mounting sleeve 511. The handle 514 is rotated clockwise or counterclockwise as needed until the tools and lamps are clamped and fixed by the clamps 517 inside the two clamps 512.

[0030] The installation of locking casters 4 facilitates the movement and fixation of the entire device.

[0031] Then, control the lifting equipment body 2 to rise to the required maintenance height. Turn the handle 510 as needed, and the screw 509, along with the mounting sleeve 511 and the two threaded sleeves 508, will rotate threadedly. This allows for fine adjustment of the left and right positions of the screw 509 and the handle 510. A limit block is fixed to the right end of the screw 509, which cooperates with the handle 510 to prevent the screw 509 from coming out of the two threaded sleeves 508. While the screw 509 is being finely adjusted left and right, the mounting sleeve 511 fixed to the outside of the screw 509 rotates circumferentially with the rotation of the screw 509, thereby achieving the effect of adjusting the angle of the clamp 512 around the screw 509, thus providing multi-angle cooperation for the tool.

[0032] By pulling the support frame 506 up or down, the adjusting slider 505 slides inside the adjusting seat 502, thereby achieving the effect of adjusting the height of the clamp 512. Under the action of the two spring pieces 503 and the two toothed plates 504 inside the adjusting seat 502, the adjusting slider 505 after the height adjustment can be limited and kept in the adjusted position.

[0033] By pulling the storage box 606 up or down, the adjusting slider 605 is slidably connected to the inner surface of the adjusting seat 602, which can achieve the effect of adjusting the height of the storage box 606, making it easier for staff to take out tools. The overall operation is simple and convenient.

[0034] For details, please refer to Figure 1 and Figure 5 In this embodiment, the support mechanism 1 includes a platform 101, a guardrail 102 is fixedly connected to the top of the platform 101, and the top of the lifting device body 2 is fixedly connected to the bottom of the platform 101.

[0035] Further reference Figure 3 and Figure 5 In this embodiment, a mounting platform 501 is symmetrically fixedly connected to the right side of the top of the guardrail 102. An adjusting seat 502 is fixedly connected to the top of the mounting platform 501. A spring piece 503 is symmetrically slidably connected to the inner surface of the adjusting seat 502. A toothed plate 504 is slidably connected to the opposite sides of the two spring pieces 503. An adjusting slider 505 is slidably connected to the opposite sides of the two toothed plates 504.

[0036] Further reference Figure 2 , Figure 3 and Figure 4 In this embodiment, support frames 506 are fixedly connected to the opposite faces of the two adjusting sliders 505. Support plates 507 are fixedly connected to the top of the support frames 506. Threaded sleeves 508 are fixedly connected to the top of the support plates 507 symmetrically on the left and right. A screw 509 is threadedly connected to the inner surfaces of the two threaded sleeves 508. The screw 509 passes through the interior of the two threaded sleeves 508. A handle 510 is fixedly connected to the left end of the screw 509.

[0037] Further reference Figure 3 and Figure 4 In this embodiment, mounting sleeves 511 are fixedly connected to the middle of opposite sides of the outer surfaces of the two screws 509. Clamps 512 are symmetrically arranged on opposite sides of the two mounting sleeves 511. The opposite sides of the two clamps 512 located at the right end are fixedly connected to the right side of the opposite side of the two mounting sleeves 511, and the opposite sides of the two clamps 512 located at the left end are slidably connected to the left side of the opposite side of the two mounting sleeves 511.

[0038] Further reference Figure 3 and Figure 4 In this embodiment, the inner surfaces of the two clamps 512 located at the same end are threaded together with a screw rod 513. The screw rod 513 passes through the interior of the two clamps 512. The left end of the screw rod 513 is fixedly connected to a handle 514, and the right end of the screw rod 513 is fixedly connected to a disc 519. The outer surface of the disc 519 is rotatably connected to a rotating sleeve 518. The left side of the outer surface of the rotating sleeve 518 is fixedly connected to the right side of the clamp 512.

[0039] Further reference Figure 3 and Figure 4 In this embodiment, elastic connecting sleeves 515 are fixedly connected to the opposite sides of the two clamps 512 located at the same end, and spring pieces 516 are slidably connected to the inner sides of the two elastic connecting sleeves 515. Clamps 517 are fixedly connected to the opposite sides of the two elastic connecting sleeves 515.

[0040] The clamping mechanism 5 can securely fix the workpiece for maintenance at the clamp 512 to prevent it from slipping during use. Under the action of the adjusting seat 502 and the screw 509, the height and angle of the workpiece can be adjusted as needed. The clamp 512 can also be used to clamp lighting fixtures, which helps to provide operators with a well-lit maintenance environment when the ambient light is not ideal, thereby helping to improve the maintenance efficiency of operators and reduce the safety threat to maintenance personnel.

[0041] Example 2

[0042] This embodiment adds a storage mechanism 6 for temporary storage of maintenance tools and parts based on embodiment one. By setting up the storage mechanism 6, these tools and parts can be stored in categories, making it convenient for operators to retrieve the parts when using them.

[0043] For details, please refer to Figure 5 and Figure 6 In this embodiment, a U-shaped buckle 601 is symmetrically engaged with the upper left side of the outer surface of the guardrail 102. An adjusting seat 602 is symmetrically fixed to the right side of the outer surface of the two U-shaped buckles 601. A spring piece 603 is symmetrically slidably connected to the inner surface of the adjusting seat 602. A toothed plate 604 is slidably connected to the opposite side of the two spring pieces 603. An adjusting slider 605 is symmetrically slidably connected to the opposite side of the two toothed plates 604.

[0044] By engaging and installing the storage mechanism 6 on the outside of the guardrail 102, these tools and parts can be stored in categories through the storage frame 606. The storage mechanism 6 is easy to assemble and disassemble from the guardrail 102, and the installation position of the storage mechanism 6 can be freely adjusted as needed. The distance between the two storage frames 606 can be adjusted up and down through the internal structure of the adjusting seat 602, making it convenient for operators to retrieve parts during use.

[0045] In this solution, the lifting equipment body 2 can adopt the X-type lifting frame in the existing technology, which takes the X-type mechanical structure as the core and realizes the lifting function through electric drive.

[0046] The locking caster wheel 4 in this solution can be a self-locking caster wheel in the prior art. It controls the locking pin or slot through its own spring, lever or electromagnetic device. When the wheel is subjected to a force in a specific direction, the locking mechanism is triggered, fixing the part of the wheel in contact with the ground and preventing rotation or slippage. The bearing of the caster wheel allows the wheel to rotate 360°, but in the locked state, the locking mechanism will restrict the rotational freedom of the bearing, so that the wheel can only maintain the current direction.

[0047] Since the above devices are all very mature products in the prior art, they will not be described in detail in this application.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
