Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipe trench support technology, specifically a collapse prevention support structure for municipal water supply and drainage pipe trench excavation. Background Technology

[0002] Municipal water supply and drainage refers to the systems and facilities in a city that involve water supply, drainage, and sewage treatment. When laying municipal water supply and drainage systems, they usually need to be buried underground to save ground space. Therefore, when using municipal water supply and drainage pipes, it is necessary to excavate water pipe trenches in the ground, and then place the municipal water supply and drainage pipes into the water pipe trenches and bury them. After the water pipe trenches are excavated, in order to prevent the water pipe trenches from collapsing and affecting the smooth laying of subsequent municipal water supply and drainage pipes, it is usually necessary to use support structures such as wooden boards or metal frames to support and protect the municipal water supply and drainage pipe trenches.

[0003] When using existing anti-collapse support structures for municipal water supply and drainage pipe trenches, after the support frame is installed inside the trench, crossbeams need to be added to ensure the support effect of the support structure on the municipal water supply and drainage pipe trench. However, adding crossbeams will prevent the subsequent water supply and drainage pipes from being smoothly placed into the trench. Consequently, the crossbeams of the support structure need to be dismantled before the water supply and drainage pipes can be placed into the trench, affecting the ease of installation of municipal water supply and drainage pipes and making it impossible to place municipal water supply and drainage pipes into the municipal water supply and drainage pipe trench supported by the support structure more conveniently and quickly.

[0004] Therefore, those skilled in the art provide a collapse-prevention support structure for municipal water supply and drainage pipe trench excavation to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to provide a collapse-proof support structure for the excavation of municipal water supply and drainage pipe trenches, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A collapse-prevention support structure for excavating municipal water supply and drainage pipe trenches includes a laying trench, in which pipes are installed, and in which a support mechanism is installed.

[0008] The support mechanism includes two frames, both of which are located inside the laying trench. Three storage cylinders are fixedly connected inside each of the two frames. A telescopic frame is slidably connected inside each storage cylinder. The upper surface of each telescopic frame contacts the outer surface of the pipe. A rotating rod is located above each of the two frames. Three cables are wound around the outer surface of each rotating rod. The end of each cable away from the rotating rod is fixedly connected to the inner wall of the telescopic frame. Two return springs are fixedly connected to the inner wall of each telescopic frame. The other end of each return spring is fixedly connected to the inner wall of the frame. Worm gears are fixedly connected to the outer surfaces of the two rotating rods. Fixed frames are fixedly connected to the upper surfaces of the two frames. Worms are rotatably connected inside each of the two fixed frames. The bottom ends of the two worms are rotatably connected inside the two frames, and the outer surfaces of the two worms mesh with the outer surfaces of the two worm gears.

[0009] As a further improvement of this utility model: several limiting plates are fixedly connected to one side of each of the two frames that are close to each other, the bottom surface of each limiting plate is in contact with the inner bottom wall of the laying groove, and the side of each limiting plate that is away from the frame is in contact with the outer surface of the pipe.

[0010] As a further improvement of this utility model: a snap-fit ​​bracket is fixedly connected to the left side of both frames, and a snap-fit ​​seat is fixedly connected to the right side of both frames.

[0011] As a further improvement of this utility model: the outer surfaces of the two rotating rods are rotatably connected to a number of stabilizing seats, and the bottom surface of each stabilizing seat is fixedly connected to the upper surface of the frame.

[0012] As a further improvement of this utility model: each of the reset springs is provided with a telescopic rod inside, one end of each telescopic rod is fixedly connected to the inner wall of the frame, and the telescopic end of each telescopic rod is fixedly connected to the inner wall of the telescopic frame.

[0013] As a further embodiment of this utility model: three fixed pulleys are fixedly connected to the inner walls of both frames, each cable passes through the fixed pulley and is slidably connected to the fixed pulley, and several limiting discs are fixedly connected to the outer surfaces of both rotating rods, with one side of each limiting disc contacting the outer surface of the cable.

[0014] As a further improvement of this utility model: a connecting plate is fixedly connected to the top of each of the two worm gears, and a handle is fixedly connected to the upper surface of each of the two connecting plates.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by incorporating a support mechanism, utilizes the telescopic frame's extension and retraction mechanism in conjunction with the storage cylinder to ensure the frame's support effect on the laying trench without hindering the smooth placement of the pipeline. Furthermore, it eliminates the need for crossbeams between the two frames or for fixing the frames with positioning pins, thus preventing crossbeams from obstructing the normal laying of the pipeline. Since no positioning pins are required to fix the frame, it does not damage the soil structure in the laying trench, ensuring the stability of the soil structure and making it less prone to collapse. Additionally, the telescopic frame's extension and retraction allows for quick and easy removal of the frame from the laying trench after the municipal water supply and drainage pipe is laid, increasing the convenience of municipal water supply and drainage pipe installation and facilitating the placement of the municipal water supply and drainage pipe into the trench supported by the support structure. This makes the use of the municipal water supply and drainage trench excavation anti-collapse support structure more convenient and efficient. Attached Figure Description

[0022] Please see Figure 1-4 A collapse-prevention support structure for excavating municipal water supply and drainage pipe trenches includes a laying trench 1, a pipe 2 installed inside the laying trench 1, and a support mechanism 3 installed inside the laying trench 1. Several limiting plates 4 are fixedly connected to the sides of two frames 301 that are close to each other. The bottom surface of each limiting plate 4 is in contact with the inner bottom wall of the laying trench 1, and the side of each limiting plate 4 away from the frame 301 is in contact with the outer surface of the pipe 2. The limiting plates 4 can restrict the position of the pipe 2 in the laying trench 1 and increase the installation accuracy of the pipe 2.

[0023] The support mechanism 3 includes two frames 301, both of which are located inside the laying groove 1. Three storage cylinders 302 are fixedly connected inside each of the two frames 301. A snap-fit ​​bracket 5 is fixedly connected to the left side of each of the two frames 301, and a snap-fit ​​seat 6 is fixedly connected to the right side of each of the two frames 301. The snap-fit ​​bracket 5, together with the snap-fit ​​seat 6, can splice multiple frames 301 together, thereby adapting to the support work of laying grooves 1 of different lengths.

[0024] Each storage tube 302 has a telescopic frame 303 slidably connected inside. The upper surface of each telescopic frame 303 is in contact with the outer surface of the pipe 2. A rotating rod 304 is provided above each of the two frames 301. Several stabilizing seats 7 are rotatably connected to the outer surface of each of the two rotating rods 304. The bottom surface of each stabilizing seat 7 is fixedly connected to the upper surface of the frame 301. The stabilizing seats 7 can limit the position of the rotating rod 304 on the frame 301, ensuring the rotational stability and reliability of the rotating rod 304.

[0025] Three cables 305 are wound around the outer surfaces of the two rotating rods 304. The end of each cable 305 away from the rotating rod 304 is fixedly connected to the inner wall of the telescopic frame 303. Two return springs 306 are fixedly connected to the inner wall of each telescopic frame 303. The other end of each return spring 306 is fixedly connected to the inner wall of the frame 301. A telescopic rod 8 is provided inside each return spring 306. One end of each telescopic rod 8 is fixedly connected to the inner wall of the frame 301. The telescopic end of each telescopic rod 8 is fixedly connected to the inner wall of the telescopic frame 303. The telescopic rod 8 can prevent the return spring 306 from excessively deflecting without affecting the extension and retraction of the return spring 306, thus improving the stability of the return spring 306 in use.

[0026] Worm gears 307 are fixedly connected to the outer surfaces of both rotating rods 304. Fixing brackets 308 are fixedly connected to the upper surfaces of both frames 301. Three fixed pulleys 9 are fixedly connected to the inner walls of both frames 301. Each cable 305 passes through the fixed pulley 9 and is slidably connected to the fixed pulley 9. Several limiting discs 10 are fixedly connected to the outer surfaces of both rotating rods 304. One side of each limiting disc 10 is in contact with the outer surface of the cable 305. The fixed pulleys 9 can limit the angle of the cable 305, prevent the cable 305 from rubbing excessively against the frame 301, and increase the ease of pulling the cable 305. The limiting discs 10 can limit the position of the cable 305 on the rotating rod 304, preventing the cable 305 from being too loose on the rotating rod 304.

[0027] Both fixed frames 308 have worm gears 309 rotatably connected inside. The bottom ends of the two worm gears 309 are rotatably connected inside the two frames 301 respectively. The outer surfaces of the two worm gears 309 are meshed with the outer surfaces of the two worm wheels 307 respectively. The top ends of the two worm gears 309 are fixedly connected to connecting plates 11. The upper surfaces of the two connecting plates 11 are fixedly connected to handles 12. The connecting plates 11 and the handles 12 can increase the ease of rotation of the worm gears 309 and increase the ease of manual operation of the worm gears 309.

[0028] The working principle of this utility model is as follows: In use, a paving trench 1 is first excavated in the ground. Then, two frames 301 are attached tightly to both sides of the paving trench 1. Multiple frames 301 are then spliced ​​together using a snap-fit ​​bracket 5 and a snap-fit ​​seat 6. At this time, due to the elastic force provided by the return spring 306, combined with the limiting force of the frames 301 and the telescopic rod 8, the telescopic frame 303 can be pushed outward from inside the storage cylinder 302. The bottom surface of the telescopic frame 303 will then contact the bottom surface of the paving trench 1. At this time, the limiting plate 4 ensures the support effect of the frames 301 on the sidewalls of the paving trench 1, preventing collapse. Furthermore, since there is no need to use positioning pins to fix the frames 301, the soil structure on the paving trench 1 will not be damaged, ensuring the stability of the soil structure and making it less prone to collapse. Since there are no crossbeams between the frames 301, the pipe 2 can be directly placed inside the paving trench 1 during installation, greatly increasing the efficiency of municipal water supply. The ease of laying drainage pipes is enhanced. When pipe 2 is laid inside the laying trench 1 under the limitation of the limiting plate 4 and the frame 301 needs to be removed, simply manually turn the handle 12 in conjunction with the connecting plate 11. This will allow the worm gear 309 to rotate in conjunction with the fixed frame 308, driving the worm wheel 307 to rotate. At this time, the cable 305 can be wound up by rotating the rod 304. When the cable 305 is wound up, it can pull the telescopic frame 303 to retract in conjunction with the fixed pulley 9, forcing the return spring 306 to retract until the telescopic frame 303 is completely retracted into the storage cylinder 302. At this time, due to the limitation of the limiting plate 4 on pipe 2, the telescopic frame 303 will completely disengage from pipe 2. Finally, simply pull the frame 301 upwards to remove it from inside the laying trench 1. This increases the ease of installation of municipal water supply and drainage pipes, making it easier for municipal water supply and drainage pipes to be placed into the municipal water supply and drainage pipe trench supported by the support structure. This makes the use of the municipal water supply and drainage trench excavation anti-collapse support structure more convenient and faster.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
