Description

Technical Field

[0001] This utility model relates to the field of municipal pipeline construction technology, specifically to an auxiliary device for the construction of road stormwater and sewage pipe networks. Background Technology

[0002] With the continuous acceleration of urbanization in my country, the scale and standards of municipal infrastructure are constantly improving. Modern cities have dense underground stormwater and sewage pipe networks, which are key infrastructure for ensuring urban flood control and drainage, maintaining road surface stability, and facilitating normal travel for citizens.

[0003] Chinese patent CN223074877U discloses an auxiliary device for road stormwater and sewage pipe network construction, including a frame, a telescopic mechanism, an interlocking mechanism, and a height adjustment mechanism. The frame has a second frame inserted into its rear end, and both the first and second frames have feet inserted into their bottom ends, with foot pads fixedly connected to the lower surface of the feet. The telescopic mechanism is located between two adjacent first frames and between two adjacent second frames. The interlocking mechanism is located between corresponding first and second frames. The height adjustment mechanism is located between the first frame and the feet, and between the second frame and the feet. This auxiliary device for road stormwater and sewage pipe network construction can replace manual labor for calibrating the position of stormwater and sewage pipes, facilitating alignment and connection of the pipes, improving the efficiency of stormwater and sewage pipe network construction, and offering strong adaptability due to its adjustable length and height. However, it still has some shortcomings that can be improved.

[0004] This utility model patent employs a cylindrical pin and positioning engagement method, adjusting the extension length of the support legs to control the angle. However, in actual construction, especially after the pipeline has been installed on the equipment, further angle adjustments become extremely difficult due to the pipeline's own weight and the overall heavy load on the equipment. Operators find it difficult to fine-tune the length of the support legs under load, thus affecting construction efficiency and pipeline positioning accuracy. Utility Model Content

[0027] The following will refer to the appendix in the embodiments of this utility model. Figure 1 To be continued Figure 7 As shown, the technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0028] Example 1:

[0029] like Figure 1 and attached Figure 2 As shown, this utility model provides an auxiliary device for the construction of road stormwater and sewage pipe networks, mainly including a U-shaped first fixing frame 1 and a second fixing frame 2. The first fixing frame 1 and the second fixing frame 2 are arranged opposite each other with their inner walls facing each other, and their two ends abut against each other. To facilitate quick assembly and disassembly, a positioning structure 10 is provided at each of the two abutment points. These two positioning structures 10 reliably connect the first fixing frame 1 and the second fixing frame 2, forming a complete U-shaped support frame.

[0030] Specifically, the positioning structure 10 includes a positioning groove 1001 formed at the end of the first fixed frame 1. A positioning block 1002 is inserted into the positioning groove 1001, and the shape of the positioning block 1002 is adapted to the inner wall of the positioning groove 1001. The positioning block 1002 is fixedly connected to the second fixed frame 2. A threaded groove is formed at the bottom end of the positioning block 1002, and a threaded hole adapted to the threaded groove is formed on the bottom wall of the second fixed frame 2. Finally, a bolt 1003 is used, passing through the threaded hole and screwed into the corresponding threaded groove, so that the position of the positioning block 1002 is fixed. This forms a stable fixation between the first fixed frame 1 and the second fixed frame 2.

[0031] Limiting frames 11 are fixedly connected to the front and rear ends of the top of the first fixed frame 1 and the front and rear ends of the top of the second fixed frame 2. The inner wall of the limiting frame 11 is in the shape of a quarter arc. At the same time, the limiting frames 11 of the first fixed frame 1 and the limiting frames 11 of the second fixed frame 2 are placed facing each other. When the first fixed frame 1 and the second fixed frame 2 are connected, the corresponding limiting frames 11 are combined to form a limiting semi-circular ring for constraining the pipeline.

[0032] Therefore, in the specific implementation process of this embodiment, after the road storm and sewage pipe network is installed, and the bottom of the sewage pipe is backfilled with soil, the bolts 1003 on the front and rear sides are unscrewed, and then the first fixing frame 1 and the second fixing frame 2 are separated to complete the use of the equipment.

[0033] Example 2:

[0034] As mentioned above, when supporting sewage pipes, it is often necessary to precisely adjust their installation angle according to design requirements. In existing technologies, a cylindrical pin and a positioning connecting groove are typically used to control the angle by adjusting the extension length of the support leg. However, in actual construction, especially after the pipe has been installed on the equipment, further angle adjustments become very difficult due to the weight of the pipe and the overall heavy load on the equipment. Operators find it difficult to fine-tune the length of the support leg 5 under load, thus affecting construction efficiency and pipe positioning accuracy. To address this issue, this utility model also provides a second embodiment, such as... Figures 1 to 7 As shown, in this second embodiment, the front and rear parts of the top ends of the first fixing frame 1 and the second fixing frame 2, which are separated by each other, are provided with connecting holes 3.

[0035] Each connection hole 3 is equipped with an independent support structure for real-time adjustment of the angle of the sewage pipe on the first fixed frame 1 and the second fixed frame 2.

[0036] Specifically, the support structure includes an equipment box 4 fixedly connected to the inner wall of the connection hole 3. A support leg 5 is inserted into the equipment box 4, and a support pad 6 is fixedly connected to the bottom end of the support leg 5. A first sliding groove 12 is formed in the middle of the two side walls of the equipment box 4. A first slider 13 is slidably connected within each first sliding groove 12, and the adjacent sides of the two first sliders 13 are fixedly connected to the outer wall of the support leg 5. This allows for the raising and lowering of the support leg 5 within a limited range.

[0037] In order to enable the outrigger 5 to achieve stable lifting and lowering, the upper part of the outrigger 5 is threadedly connected to a threaded rod 7, and a rotating handle 8 is provided on the top of the equipment box 4. A limit device 9 is connected between the rotating handle 8 and the threaded rod 7, which can achieve self-locking after the threaded rod 7 is rotated, thereby reliably maintaining the extended position of the outrigger 5.

[0038] Specifically, such as Figures 4 to 7 As shown, the limiting device 9 includes a rotating hole at the top of the equipment box 4. A rotating shaft 901 is rotatably connected to the inner wall of the rotating hole. The bottom end of the rotating shaft 901 is fixedly connected to the top end of the threaded rod 7. A protective box 908 is fixedly connected to the top of the equipment box 4. A through hole is opened in the middle of the top of the protective box 908. A connecting shaft 909 is inserted into the through hole. The top end of the connecting shaft 909 is fixedly connected to the bottom end of the rotating handle 8.

[0039] The top of the rotating shaft 901 is fixedly connected to a fixed housing 902. The fixed housing 902 has a second slide groove 903 on each of its two side walls. A second slider 904 is slidably connected in each second slide groove 903. The adjacent sides of the two second sliders 904 are fixedly connected to a receiving shaft 905.

[0040] The bottom end of the receiving shaft 905 is fixedly connected to a limiting telescopic rod 906. The bottom end of the limiting telescopic rod 906 is fixedly connected to the middle of the bottom wall of the fixed housing 902. A shock-absorbing spring 907 is provided around the limiting telescopic rod 906. The top and bottom ends of the shock-absorbing spring 907 are fixedly connected to the bottom end of the receiving shaft 905 and the bottom wall of the fixed housing 902, respectively.

[0041] To enhance the self-locking function of the threaded rod 7 after rotation, a ratchet limiting mechanism is provided between the receiving shaft 905 and the protective box 908 to restrict the rotation of the receiving shaft 905. A positioning ratchet 9010 is fixedly connected to the bottom end of the connecting shaft 909, and the bottom end of the positioning ratchet 9010 is fixedly connected to the receiving shaft 905. At the same time, a ratchet groove 9011 adapted to the positioning ratchet 9010 is opened in the middle of the top wall of the protective box 908, and the positioning ratchet 9010 is inserted into the ratchet groove 9011.

[0042] Working principle: In the non-operating state, the preload of the shock-absorbing spring 907 continuously acts upward on the receiving shaft 905, thereby driving the positioning ratchet 9010, which is fixed to the top of the receiving shaft 905, to reliably engage in the ratchet groove 9011 on the top wall of the protective box 908. At this time, the positioning ratchet 9010 cannot rotate due to the locking characteristic of the ratchet teeth (i.e., preventing the threaded rod 7 from rotating). Then, through the cooperation of the receiving shaft 905, the second slider 904, and the second slide groove 903, the rotation tendency of the fixed housing 902 and its lower rotating shaft 901 and the threaded rod 7 is locked. This ensures that the threaded rod 7 will not reverse when bearing the pipeline load, thereby maintaining a constant extension length of the support leg 5 and effectively preventing pipeline settlement caused by support retraction.

[0043] When the extension length of the outrigger 5 needs to be adjusted, the operator applies a downward pressure to the rotating handle 8 sufficient to overcome the preload of the shock-absorbing spring 907. This pressure is transmitted to the positioning ratchet 9010 via the connecting shaft 909, causing the receiving shaft 905 fixed thereto to move downwards, disengaging the teeth of the positioning ratchet 9010 from the ratchet groove 9011 on the protective housing 908, thus releasing the self-locking state. At this time, by maintaining the downward pressure and rotating the handle 8, power will sequentially drive the threaded rod 7 to rotate via the connecting shaft 909, the disengaged positioning ratchet 9010, the receiving shaft 905, the sliding pair formed by the second slider 904 and the second slide groove 903, the fixed housing 902, and the rotating shaft 901. Since the rotation of the outrigger 5 is restricted by the engagement of the first slider 13 and the first slide groove 12, the rotational motion of the threaded rod 7 will be converted into the linear lifting motion of the outrigger 5. After adjusting to the required length, release the rotating handle 8. The restoring force of the shock-absorbing spring 907 will push the receiving shaft 905 and the positioning ratchet 9010 to reset, so that they re-engage in the ratchet groove 9011, achieving automatic locking and thus firmly maintaining the new support height.

[0044] In summary, the auxiliary equipment for road stormwater and sewage pipeline construction provided by this utility model has at least the following advantages:

[0045] The advantage of this invention lies in its unique limiting device 9. Through the operation of "pressing down to unlock, rotating to adjust, and releasing to self-lock," a ratchet mechanism is cleverly utilized to achieve the engagement and disengagement of the transmission chain. This allows operators to precisely adjust the height of the outrigger 5 with minimal force under heavy pipeline loads, solving the problem in the previously disclosed technology where adjustment was difficult or even impossible under load, significantly reducing labor intensity and operational risks.
