Description

Technical Field

[0001] This utility model relates to the field of tunnel maintenance technology, and in particular to a tunnel maintenance operation platform. Background Technology

[0002] A tunnel maintenance work platform is a mobile or fixed work device specifically designed for the inspection, maintenance, and repair of facilities inside tunnels. It provides maintenance personnel with a safe, stable, and easy-to-operate workspace. A tunnel maintenance work platform typically consists of a ladder truck composed of a support frame, diagonal braces, a climbing plate, and a platform. Workers move the ladder truck to a suitable location and then climb onto the platform to carry out maintenance work.

[0003] In existing ladder truck structures, there is no extension platform at the top of the ladder truck to extend the working range, which means that workers can only work in a limited space. The working range is small and maintenance is extremely inconvenient. In some ladder truck structures that are equipped with extension platforms, the extension platforms are fixed and cannot be folded for storage, which makes the upper part of the entire ladder truck large, difficult to move, and also not conducive to storage.

[0017] 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.

[0018] like Figures 1-3 As shown, a tunnel maintenance work platform includes a support frame 1. A base frame 2 is fixedly installed at the lower end of the support frame 1, and diagonal braces 3 are provided on the base frame 2. A raised platform 5 is provided at the upper end of the support frame 1, and an extension platform structure 6 is connected to the raised platform 5. The lower end of the extension platform structure 6 is connected to the support frame 1. The support frame 1 and the base frame 2 are welded together, and wheels are provided on the base frame 2. The upper ends of the diagonal braces 3 are connected to the support frame 1, and climbing plates 4 are provided between the diagonal braces 3. Handrails 8 are fixed on the diagonal braces 3. Guardrails 7 are fixedly installed on the raised platform 5.

[0019] When using the maintenance platform, the entire device is moved using the wheels on the base frame 2. After moving the device to a suitable position inside the tunnel and ensuring its stable placement, the extended platform structure 6 is assembled. The support structure within the extended platform structure 6 is then flipped open and connected before use. Workers climb onto the elevated platform 5 at the top of the support frame 1 via the climbing plate 4 on the diagonal brace 3. They then stand and move around on the elevated platform 5 and the extended platform structure 6 to complete the maintenance work. During maintenance, the guardrail 7 provides protection to ensure the safety of the workers. After maintenance is completed, the handrail 8 provides auxiliary support and protection when descending from the climbing plate 4, further improving safety.

[0020] According to the above implementation scheme, the extended platform structure 6 includes a rotating support frame 601, a pin 602, a connecting screw hole 603, a tilting platform 604, a rotating connecting seat 605, a connecting block 606, a protective component 607, and a round hole 608. One end of the rotating support frame 601 is connected to the pin 602, and the pin 602 is connected to the bracket 1. The rotating support frame 601 is rotatably connected to the bracket 1 through the pin 602. The connecting screw hole 603 is opened at the other end of the rotating support frame 601. The tilting platform 604 is rotatably mounted on the rotating connecting seat 605, and the rotating connecting seat 605 is fixedly connected to the high platform plate 5. The connecting block 606 is fixed on the lower surface of the tilting platform 604, and the connecting block 606 is connected to the rotating support frame 601. The round hole 608 is opened on the tilting platform 604. The protective component 607 is fixedly mounted on the tilting platform 604.

[0021] When opening the extended platform structure 6, first assemble the protective component 607 and install it into the round hole 608 on the tilting platform 604. Then, tilting platform 604 and protective component 607 are tilted upwards to ensure that tilting platform 604 is in a horizontal position. Next, using pin 602, tilt the rotating support frame 601 upwards, so that the upper end of the rotating support frame 601 rotates to the connecting block 606. Use screws to fix the connecting block 606 to the rotating support frame 601, thus completing the fixation of tilting platform 604. During use, when workers stand on tilting platform 604 to perform maintenance work, the rotating support frame 601, together with the rotating connecting seat 605, provides stable support for tilting platform 604, while the protective component 607 acts as a protective barrier, ensuring the safety of high-altitude operations.

[0022] The protective component 607 includes a vertical rod 6071, a stud 6072, a nut 6073, a long horizontal rod 6074, a short horizontal rod 6075, a slot 6076, and a connecting rod 6077. The vertical rod 6071 is fixedly connected to the stud 6072, and the stud 6072 passes through the round hole 608. The nut 6073 is connected to the stud 6072. The long horizontal rod 6074 and the short horizontal rod 6075 are arranged on the vertical rod 6071. The slot 6076 is opened on the short horizontal rod 6075. The end of the connecting rod 6077 is inserted into the slot 6076 on the short horizontal rod 6075.

[0023] When installing the protective assembly 607, insert the connecting rod 6077 into the slot 6076 on the short horizontal bar 6075, and then place the vertical bar 6071 onto the tilting platform 604, so that the stud 6072 passes through the round hole 608. A nut 6073 is then placed on the stud 6072 to secure the vertical bar 6071, thus connecting the entire protective assembly 607 to the tilting platform 604. During use, the vertical bar 6071, in conjunction with the long horizontal bar 6074, the short horizontal bar 6075, and the connecting rod 6077, provides protection and ensures safety during maintenance.

[0024] It should be noted that by setting an extension platform structure 6 at the high platform plate 5 at the upper end of the support 1, the working space can be increased during maintenance operations, improving the convenience of maintenance. The flip platform 604 is installed through the rotating connecting seat 605 and used in conjunction with the rotating support frame 601. When in use, it can be unfolded to ensure stability. When not in use, it can be folded down for storage, facilitating storage. A detachable protective component 607 is adopted. When the flip platform 604 is in use, the protective component 607 is fixed to the flip platform 604 for protection. When the flip platform 604 is not in use, the protective component 607 can be removed and stored separately, saving space.

[0025] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
