[0001] The utility model relates to the technical field of construction safety equipment, in particular to a safety equipment for pipe jacking construction of municipal roads. Background Technique
[0002] Pipe jacking construction is an underground pipeline construction technology and also a widely used technology in the modern urbanization process. This technology involves excavating a long passage underground, introducing the pipeline materials to be laid from the top into the passage, and then using mechanical equipment for construction to complete the laying and installation of the entire pipeline. The characteristics of pipe jacking construction are small construction site, less impact on the ground, relatively low noise, and the ability to operate deep underground, which are advantages that cannot be compared with open-cut pipe laying. However, pipe jacking technology also has disadvantages, such as long construction time and high project cost, and is applicable to the laying of various pipelines, such as sewage pipes, cables, pipelines, etc.
[0003] However, it still has some disadvantages. For example: Usually during the construction process, the crane hoists the precast pipe into the working well, and workers need to wait in the working well to assist in sealing the connection between the hoisted precast pipe and the pipe being jacked at the front end. During this process, there may be a possibility that the precast pipe is not placed stably and may roll or displace, which may cause certain harm to workers. Moreover, the installation direction of the hoisted pipe usually needs to be finely adjusted, lacking adjustable equipment, and manual operation is relatively laborious and there are also certain operation risks.
[0004] To solve the above problems, a safety equipment for pipe jacking construction of municipal roads is proposed in this application. Content of the Utility Model

Detailed Description of the Preferred Embodiment
[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0021] Please refer to Figures 1-4 , the present utility model provides a technical solution: a safety device for pipe jacking construction of municipal roads, including a fixed base 1. A rotating shaft 2 is movably sleeved in the inner cavity of the fixed base 1. The upper outer surface of the rotating shaft 2 is fixedly connected with a support block 3. The upper outer surface of the support block 3 is fixedly connected with a base block 4. One side outer surface of the base block 4 is fixedly connected with an ejecting assembly 5. An activity groove 6 is opened on the upper outer surface of the support block 3. A sliding strip 7 is fixedly connected to the upper outer surface of the support block 3. The outer wall of the sliding strip 7 is slidably connected with a moving block 8. By virtue of the rotatable ability of the provided rotating shaft 2, it can cooperate with the second motor 18 to drive the second threaded rod 20 to rotate, and drive the movable block 22 to move back and forth between the two ends of the second threaded rod 20, so as to enable the support block 3 to move back and forth on both sides of the fixed base 1. In this way, during the docking process of the front and rear two sections of pipes, it is convenient to make a micro-adjustment of the docking direction or angle of the pipes.
[0022] In this embodiment, as Figures 2-3As shown in the figure, a sliding groove 9 is formed on the outer surface of the upper end of the moving block 8. A fixing block 10 is fixedly connected to the outer surface of the upper end of the moving block 8. There are two groups of fixing blocks 10. An arc-shaped clamping block 11 is movably connected to the outer surface of the upper end of the moving block 8. There are two groups of arc-shaped clamping blocks 11. A first threaded rod 12 is movably connected to the inner cavity of the moving block 8. One end of the first threaded rod 12 is fixedly connected to a connecting rod 13. One end of the connecting rod 13 is movably connected to a first motor 14. Sliders 15 are fixedly connected to the outer surfaces of the lower ends of the two groups of arc-shaped clamping blocks 11. A telescopic rod 16 is fixedly connected to one side outer surface of the two groups of arc-shaped clamping blocks 11. A spring 17 is movably sleeved on the outer wall of the telescopic rod 16. The pipeline can be positioned and clamped by the provided arc-shaped clamping blocks 11. Sliders 15 are arranged at the lower ends of the two groups of arc-shaped clamping blocks 11, and a telescopic rod 16 and a spring 17 are arranged at one end of the two groups of arc-shaped clamping blocks 11 close to the fixing block 10. In this way, the crane can directly place the lifted pipeline between the two groups of arc-shaped clamping blocks 11. The elastic force of the spring 17 can drive the arc-shaped clamping blocks 11 to clamp towards both sides of the pipeline, so as to limit the pipeline. This can not only prevent the pipeline from rolling or displacing during the process of workers assisting in pipeline connection, thus affecting the construction operation of workers and delaying the construction progress, but also prevent the pipeline from rolling or displacing and squeezing the construction workers, thereby avoiding certain dangers.
[0023] In this embodiment, as Figure 4 shown, a second motor 18 is fixedly connected to the outer surface of the upper end of the fixed base 1. One end of the second motor 18 is movably connected to a connecting pipe 19. A second threaded rod 20 is fixedly connected to the outer surface of one end of the connecting pipe 19. Limit blocks 23 are fixedly connected to the outer surface of the upper end of the fixed base 1. There are two groups of limit blocks 23. A clamping strip 21 is fixedly connected to the adjacent side outer surfaces of the two groups of limit blocks 23. An activity block 22 is movably sleeved on the outer wall of the clamping strip 21. The outer surface of the upper end of the activity block 22 is fixed to the outer surface of the lower end of the support block 3. The provided second motor 18 can drive the second threaded rod 20 to rotate by using the connecting pipe 19, so as to drive the activity block 22 to move back and forth between the two ends of the second threaded rod 20, and further drive the support block 3 to move back and forth on the left and right sides of the fixed base 1. In this way, during the process of the prefabricated pipeline at the rear end docking with the prefabricated pipeline at the front end, it is convenient to make a micro adjustment of the docking direction or angle of the pipeline. By driving the first threaded rod 12 to rotate by the provided first motor 14, the moving block 8 can be further driven to move back and forth. In this way, the pipeline on the upper end of the moving block 8 can be driven to move back and forth, which is convenient to adjust the pipeline to the most accurate connection position, convenient for operation, and beneficial to increasing the sealing performance at the pipeline interface. It can prevent the sealing effect from being poor due to the non-conforming angle position of the pipeline docking, resulting in leakage during the later use process, causing soil erosion, and further causing the occurrence of ground settlement or uplift, thereby increasing the possibility of failures and further increasing the maintenance cost.
[0024] Working principle:
[0025] When using this product, first, the pipeline can be positioned and clamped by the set arc-shaped clamping blocks 11. Sliders 15 are arranged at the lower ends of the two groups of arc-shaped clamping blocks 11, and telescopic rods 16 and springs 17 are arranged at one end of the two groups of arc-shaped clamping blocks 11 close to the fixed block 10. In this way, the crane can directly place the lifted pipeline between the two groups of arc-shaped clamping blocks 11. The elastic force of the spring 17 can drive the arc-shaped clamping blocks 11 to clamp the pipeline on both sides, so as to limit the pipeline, avoid the pipeline from rolling or displacing during the process of workers assisting in pipeline connection, which affects the construction operation of workers and delays the construction progress, and also avoid the pipeline from rolling or displacing and squeezing the construction workers, thus avoiding certain dangers. Then, the rotation shaft 2 can cooperate with the second motor 18 to drive the second threaded rod 20 to rotate by means of the connecting pipe 19, so as to drive the movable block 22 to move back and forth between the two ends of the second threaded rod 20, and further drive the support block 3 to move back and forth on the left and right sides of the fixed base 1. In this way, during the process of the prefabricated pipeline at the rear end docking with the prefabricated pipeline at the front end, it is convenient to make micro-adjustments to the docking direction or angle of the pipeline. The first motor 14 drives the first threaded rod 12 to rotate, which can further drive the moving block 8 to move back and forth. In this way, the pipeline on the upper end of the moving block 8 can be driven to move back and forth, which is convenient to adjust the pipeline to the most accurate connection position, is convenient for operation, and is beneficial to increasing the sealing performance at the pipeline interface.
