Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a support device for pipe gallery construction. Background Technology

[0002] Utility tunnels are public tunnels built underground in cities to centrally lay municipal pipelines such as electricity, communications, radio and television, water supply, drainage, heating, and gas. They improve the efficiency of urban space utilization and the convenience of maintenance and management. Currently, during the construction of the foundation pit for utility tunnels, it is usually necessary to use two opposing support plates placed on both sides inside the foundation pit for support and protection.

[0003] The existing support device for integrated utility tunnel construction (authorization announcement number: CN218667566U) realizes the assembly and support of the support plates, has a wide range of applications, improves work efficiency, and reduces construction costs. However, in the process of constructing the foundation pit of the utility tunnel, the support plates are supported by welded steel frames, which makes it inconvenient to adjust the spacing between the two support plates according to the size of the foundation pit, reduces applicability, and makes it inconvenient to disassemble and replace the support plates. Therefore, this utility model is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] During the construction of the utility tunnel, a support device is required. The support device provided by this utility model is specifically used to support both sides inside the foundation pit. The telescopic adjustment component controls the support angle of the first rotating support rod 304 and the second rotating support rod 305, thereby adjusting the distance between the two support plates 1 and improving applicability. Before using the support device, it is necessary to carry out preparatory work such as inspection to ensure the normal use of the device.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a support device for pipe gallery construction, including support plates 1, which are symmetrically arranged. A telescopic adjustment component is provided between the two support plates 1. An installation structure is provided on the support plates 1. The installation structure includes side U-shaped blocks 3 symmetrically arranged on the upper and lower parts of the opposite surfaces of the two support plates 1. A slider 302 is slidably inserted in the side U-shaped blocks 3. A baffle 301 fixed on the side U-shaped blocks 3 is provided on one side of the slider 302. The telescopic adjustment component includes an arched plate 2 arranged between the two support plates 1. A bottom plate 201 is fixed to the bottom of the arched plate 2. A bidirectional screw rod 202 is rotatably inserted between the arched plate 2 and the vertical plate. Limiting crossbars 203 are symmetrically arranged on the upper and lower sides of the bidirectional screw rod 202. The limiting crossbars 203 are fixedly inserted on the arched plate 2.

[0021] In this embodiment, a rotating motor is connected to one end of the bidirectional lead screw 202. The rotating motor is mounted on the arched plate 2, and a dustproof housing is provided on the outside of the rotating motor. Sleeve blocks 204 are symmetrically and appropriately fitted at both ends of the bidirectional lead screw 202 and the limiting crossbar 203. Multiple dustproof elastic covers 205 are fitted on the outside of the bidirectional lead screw 202. The dustproof elastic covers 205 are respectively connected to the arched plate 2 and the sleeve blocks 204. L-shaped rods 306 are symmetrically fixed at the top and bottom positions on both sides of the sleeve blocks 204. A shaft rod 303 is fixed on the top surface of the slider 302 located at the top position, and a shaft rod 303 is fixed on the bottom surface of the slider 302 located at the bottom position. It should be noted that the rotating motor is a servo motor with a self-locking function in the prior art, and the dustproof housing and dustproof elastic covers 205 are prior art.

[0022] In this embodiment, a first rotating support rod 304 and a second rotating support rod 305 are rotatably sleeved on the shaft rod 303. The first rotating support rod 304 and the second rotating support rod 305 are rotatably sleeved on the L-shaped rod 306 at the corresponding positions. The first rotating support rod 304 and the second rotating support rod 305 are V-shaped. An arched locking rod 307 is provided in the middle of the inner side of the support plate 1. The arched locking rod 307 is adapted to be inserted through the side U-shaped block 3 and the slider 302. The lower part of the arched locking rod 307 is bolted with a nut, and the nut is in contact with the bottom surface of the side U-shaped block 3 at the bottom position.

[0023] In this embodiment, a vertical block 101 is fixed to one end face of the support plate 1, and a vertical groove 102 is opened on the other end face of the support plate 1. The vertical block 101 is adapted to the vertical groove 102. Limiting rods 401 are fixed at the four corners of the opposite face of the support plate 1. Limiting tubes 4 are movably sleeved on the limiting rods 401. The limiting tubes 4 are fixed as a whole with the arched plate 2. Through the setting of the telescopic adjustment component and the installation structure, the bidirectional screw 202 rotates, thereby driving the two sets of blocks 204 to move closer or further away from each other, thereby adjusting the support angle of the first rotating support rod 304 and the second rotating support rod 305, adjusting the distance between the two support plates 1, and improving applicability. At the same time, the setting of the arched locking rod 307 and the side U-shaped block 3 makes it easy to disassemble the slider 302 and the support plate 1, thereby facilitating the replacement of the support plate 1. The limiting rods 401 and the limiting tubes 4 play a role in limiting and stabilizing.

[0024] Working principle: When using this support device to support the foundation pit, ensure that the U-shaped block 3 and slider 302 on the opposite side of the arched locking rod 307 are locked and fixed. The limiting tube 4 and the limiting rod 401 are inserted in a matching manner. Adjust the spacing of the support plate 1 according to the size of the foundation pit. Control the start of the rotating motor so that the two sets of blocks 204 move closer to each other, thereby making the two support plates 1 move further apart and increasing the spacing between the two support plates 1. After the adjustment is completed, place the device in the foundation pit for support operations. The vertical block 101 and the vertical groove 102 facilitate the cooperation of multiple devices for support.
