Description

Technical Field

[0001] This utility model relates to the technical field of tunnel maintenance brackets, and in particular to a maintenance bracket for ventilation equipment in tunnels. Background Technology

[0002] Tunnel ventilation equipment is typically used at the top of the tunnel to promote air circulation within the tunnel. In long tunnels, several sets of ventilation equipment are usually evenly distributed to achieve relay ventilation and normal air exchange over long distances; however, to achieve relay ventilation, it is necessary to ensure the normal operation of adjacent ventilation equipment, so the ventilation equipment needs to be inspected and maintained frequently.

[0003] Currently, tunnel ventilation equipment is generally fixed directly to the top of the roadway inside the tunnel, such as Chinese patent CN109340149A, a height-adjustable shock-absorbing ventilator for tunnels. Therefore, workers need to use ladders or scaffolding for high-altitude operations during maintenance, which makes maintenance work difficult, inefficient, and dangerous. Therefore, there is a need for an installation device that can facilitate the maintenance of ventilation equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems and provide a support bracket for the installation and maintenance of ventilation equipment in tunnels.

[0005] The technical solution of this utility model is: a mounting and maintenance bracket for ventilation equipment inside a tunnel, wherein the ventilation equipment is fixedly installed inside the tunnel; the ventilation equipment is mounted on the mounting and maintenance bracket; the mounting and maintenance bracket includes an arc-shaped bracket, the curvature of which matches the curvature of the upper sidewall of the tunnel, both ends of the arc-shaped bracket are fixed to both sides inside the tunnel, and the top of the arc-shaped bracket is close to the top of the tunnel. The ventilation equipment is mounted on the top of the arc-shaped bracket, and the arc-shaped bracket matches the shape of the tunnel, allowing the ventilation equipment to be installed at a high position inside the tunnel. When maintenance of the ventilation equipment is required, the arc-shaped bracket can be laid down, making the maintenance work of the ventilation equipment easier.

[0006] Preferably, the arc-shaped bracket has a square cross-section, and the ventilation equipment is installed on the top and lower side of the arc-shaped bracket. The square cross-section of the arc-shaped bracket provides a good installation position for the ventilation equipment.

[0007] Preferably, square reserved chambers are provided on both sides of the tunnel interior, and the two ends of the arc-shaped support are located in the reserved chambers. This avoids the two ends of the arc-shaped support occupying the limited walking space inside the tunnel.

[0008] Furthermore, support plates are provided at both ends of the arc-shaped bracket. This increases the overall contact area between the arc-shaped bracket and the ground, resulting in greater stability.

[0009] Furthermore, the bottom of the support plate is equipped with columns. These columns can support the arc-shaped bracket, increasing its height and thus freeing up space in the lower part of the tunnel.

[0010] Furthermore, the support plate has protruding lugs on both its front and rear sides. This facilitates the lifting and lowering of the arc-shaped support using hydraulic rods or jacks.

[0011] Furthermore, the height of the column matches the height of the reserved cavity.

[0012] The beneficial effects of this utility model are as follows: The tunnel ventilation equipment installation and maintenance bracket of this utility model has the following advantages: 1. This utility model fixes the tunnel ventilation equipment on the arc-shaped bracket, and then fixes the arc-shaped bracket to the designated position. When the ventilation equipment is being inspected, the arc-shaped bracket can be lowered directly, avoiding the need for maintenance personnel to work at height.

[0013] 2. The arc-shaped bracket of this utility model is equipped with support plates at both ends, which can be lifted by hydraulic equipment. After being lifted into place, the column is placed, thus ensuring the stability of the arc-shaped bracket. Attached Figure Description

[0016] Example 1: See Figure 1-6A mounting bracket for ventilation equipment inside a tunnel is disclosed. Ventilation equipment 02 is fixedly installed inside the tunnel 00. The ventilation equipment 02 is mounted on the mounting bracket. The mounting bracket includes an arc-shaped support 1, the curvature of which matches the curvature of the upper sidewall inside the tunnel 00. Both ends of the arc-shaped support 1 are fixed to the sides inside the tunnel 00, and the top of the arc-shaped support 1 is close to the top of the tunnel 00. The ventilation equipment 02 is mounted on the top of the arc-shaped support 1. The arc-shaped support 1 conforms to the shape of the tunnel 00, allowing the ventilation equipment 02 to be installed at a high position inside the tunnel 00. When maintenance of the ventilation equipment 02 is required, the arc-shaped support 1 can be laid down, making maintenance easier.

[0017] The arc-shaped bracket 1 has a square cross-section, and the ventilation device 02 is installed on the top and lower side of the arc-shaped bracket 1. The square cross-section of the arc-shaped bracket 1 provides a good installation position for the ventilation device 02.

[0018] Square reserved chambers 01 are set on both sides inside the tunnel 00, and the two ends of the arc-shaped support 1 are set in the reserved chambers 01. This avoids the two ends of the arc-shaped support 1 occupying the limited walking space inside the tunnel 00.

[0019] Support plates 11 are provided at both ends of the arc-shaped bracket 1. Increasing the overall contact area between the arc-shaped bracket 1 and the ground makes it more stable.

[0020] A column 12 is provided at the bottom of the support plate 11. It can support the arc-shaped bracket 1, increase the height of the arc-shaped bracket 1, and thus free up the space under the tunnel 00.

[0021] In this embodiment, column 12 is made of I-beam.

[0022] The support plate 11 has protruding ear plates 111 on both the front and rear sides. This facilitates the lifting and lowering of the arc-shaped support 1 by equipment such as hydraulic rods or jacks.

[0023] The height of column 12 matches the height of reserved cavity 01.

[0024] The working process of this embodiment includes the following steps: ① Transport the arc-shaped bracket 1 to the required installation location and lay it down on the ground; ② Install ventilation equipment 02, etc. on the arc-shaped bracket 1, and extend and fix the cable from the arc-shaped bracket 1; ③ Pull the arc-shaped support 1 into a standing position; ④ Place several jacks or other lifting equipment at the bottom of the support plate 11 ear plate 111 to lift the arc-shaped support 1; ⑤ After raising to the designated height, place the column 12 below the support plate 11 and fix it to the bottom of the tunnel 00; ⑥ Lower the support plate 11 of the arc-shaped bracket 1 onto the top of the column 12 and then fix it.

[0025] The arc-shaped bracket 1 has been installed.

[0026] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the column 12 is a liftable column 12, and the bottom of the tunnel 00 is provided with a recess that matches the height and outline of the liftable column 12. The bottom of the liftable column 12 is fixed in the recess at the bottom of the tunnel 00. The liftable column 12 can be used to directly support the arc-shaped bracket 1, which facilitates the lifting and adjustment of the arc-shaped bracket 1 and makes maintenance more convenient.
