[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A municipal pipeline trench support structure includes a body 1. Threaded sleeves 21 are fixedly connected to the four corners of the lower end of the body 1. Each of the four threaded sleeves 21 has a threaded screw 22 threaded inside. Each of the four screws 22 has a pad 23 fixedly connected to its lower end. The body 1 is a support device used during municipal pipeline construction to prevent trench collapse and to support the trench. Through the use of the body 1 and its supporting components, the pipeline trench can be supported to prevent collapse. The threaded sleeves 21 have internal threads, and the screws 22 have external threads. The internal and external threads allow the screws 22 to extend and retract within the threaded sleeves 21 when they rotate. The extension and retraction of the screws 22 causes the pads 23 to rise and fall, with the pads 23 pressing against the ground. The rising and falling of the pads 23... The height of the machine body 1 can be adjusted to suit different installation heights. Handles 20 are fixedly connected to both sides of the upper end of the machine body 1, providing easy grip and facilitating movement. Two control buttons 18 are located in the middle of the upper end of the machine body 1, which is also equipped with a protective cover 19. One side of the protective cover 19 is rotatably connected to the upper end of the machine body 1. Both control buttons 18 are located within the protective cover 19. The control buttons 18 are connected to the supporting components for stable operation and can be programmed for automatic operation. The two control buttons 18 are used to control the extension and retraction of the supporting components on both sides of the machine body 1. The protective cover 19 protects the two control buttons 18 from being touched when not in use.

[0025] Reference Figure 1-3 The machine body 1 has two support plates 12 on both sides. The two support plates 12 are used to insert into the two sides of the pipe trench. The two support plates 12 can support the two sides of the pipe trench. The supporting components on both sides of the machine body 1 extend to support the two support plates 12, which can prevent the two support plates 12 from moving towards each other. Thus, the pipe trench can be supported by the two support plates 12. A power mechanism is provided on one inner wall of the machine body 1. The power mechanism is provided with four positive and negative threaded rods 6. The four positive and negative threaded rods 6 are all set in the machine body 1. The positive and negative threaded rods 6 are rods with opposite threads on both sides. By rotating the four positive and negative threaded rods 6, the supporting components on both sides of the four positive and negative threaded rods 6 can move towards or away from each other. A fixing plate 7 is fixedly connected to the middle of the machine body 1. The middle of the four positive and negative threaded rods 6 are rotatably sleeved on the fixing plate 7. The fixing plate 7 is used to support the four positive and negative threaded rods 6, so that the four positive and negative threaded rods 6 can rotate within the machine body 1.

[0026] Reference Figure 2 , 3The power mechanism includes a motor 2 fixedly mounted on the inner wall of one side of the machine body 1. A drive sprocket 3 is fixedly connected to the end of the output shaft of the motor 2. The motor 2 and its supporting components are connected for stable operation and can be programmed for automatic operation. Two control buttons 18 control the forward and reverse operation of the motor 2, respectively. The operation of the motor 2 drives the drive sprocket 3 to rotate. The upper and lower parts of the drive sprocket 3 are connected to two first sprockets 5 via a first chain 4. The two first sprockets 5 are fixedly sleeved in the middle of two threaded rods 6 with opposite threads. The rotation of the drive sprocket 3 drives the first chain 4 to rotate, which in turn drives the two first sprockets 5 to rotate, and the two first sprockets 5 drive the two threaded rods 6 with opposite threads to rotate. A telescopic mechanism is provided in the middle of the four threaded rods 6. The telescopic mechanism includes four second sprockets 8 that are fixedly sleeved in the middle of the four threaded rods 6. Corresponding two second sprockets 8 are connected by a second chain 9. The second sprockets 8 and the threaded rods 6 are fixedly connected. The rotation of the second sprockets 8 will drive the threaded rods 6 to rotate. At the same time, the threaded rods 6 will also drive the second sprockets 8 to rotate. The rotation of two threaded rods 6 will drive two of the second sprockets 8 to rotate. The two second sprockets 8 will drive two of the second chains 9 to rotate. The two second chains 9 will drive the other two second sprockets 8 to rotate. The four second sprockets 8 will drive the four threaded rods 6 to rotate synchronously.

[0027] Reference Figure 1 , 24. Each of the four threaded rods 6 has a threaded sleeve 10 threaded on both sides. The eight threaded sleeves 10 are slidably fitted onto both sides of the machine body 1. The threaded sleeves 10 have internal threads. Synchronous rotation of the four threaded rods 6 will push the eight threaded sleeves 10 to move in opposite directions, causing them to extend and retract on both sides of the machine body 1. Two transverse grooves 13 are opened on opposite sides of each of the two support plates 12. A transverse plate 11 is inserted into each of the four transverse grooves 13. The other ends of the eight threaded sleeves 10 are fixedly connected to both sides of the four transverse plates 11. The movement of the eight threaded sleeves 10 in opposite directions will cause the four transverse plates 11 to move in opposite directions. The four transverse plates 11, moving in opposite directions, will be inserted into the corresponding four transverse grooves 13. The four transverse plates 11 inserted into the four transverse grooves 13 can support the two support plates 12. The structure of the transverse plates 11 inserted into the transverse grooves 13... The structure can limit the stability of the horizontal plate 11 when supporting the support plate 12, and prevent the horizontal plate 11 from moving arbitrarily when supporting the support plate 12. The spacing of the four horizontal plates 11 can be adjusted according to the spacing between the two support plates 12, so as to adjust the support width of the four horizontal plates 11 on the two support plates 12 according to the width of the pipe trench. In this way, it can support pipe trenches of different widths, effectively improving the practicality of the body 1. Both sides of the four horizontal grooves 13 are fixedly connected with the locking blocks 14, and two locking slots 15 are opened on the other side of the four horizontal plates 11. The eight locking blocks 14 are respectively inserted into the corresponding eight locking slots 15. When the four horizontal plates 11 are inserted into the four horizontal grooves 13, the eight locking blocks 14 will be inserted into the eight locking slots 15. Through the structure of the eight locking blocks 14 being inserted into the eight locking slots 15, the stability of the horizontal plate 11 in the horizontal groove 13 can be improved.

[0028] Reference Figure 1 , 2 Each of the eight threaded sleeves 10 has an inner retaining ring 16 fixedly fitted at one end of each other. The eight inner retaining rings 16 are all located inside the machine body 1. Each of the eight threaded sleeves 10 has an outer retaining ring 17 fixedly fitted on it. The eight outer retaining rings 17 are located on both sides of the machine body 1. The inner retaining rings 16 are used to limit the extension distance of the threaded sleeves 10 outward from the machine body 1, and the outer retaining rings 17 are used to limit the retraction position of the threaded sleeves 10 inward from the machine body 1. Through the structure of the inner retaining rings 16 and the outer retaining rings 17, the threaded sleeves 10 can be prevented from falling off from both sides of the machine body 1.

[0029] In this utility model, during use: two support plates 12 are respectively installed on both sides of the trench, the machine body 1 is placed in the trench, and the height of the machine body 1 is adjusted to the corresponding position.
