Description

Technical Field

[0001] This utility model relates to the field of sewage pipe laying technology, specifically a sewage pipe laying device for sewage treatment plants. Background Technology

[0002] Sewage pipes are crucial facilities for urban sewage collection and transportation. Their workflow involves sewage first flowing from branch pipes into main pipes, then into the main trunk line, and finally being transported to a sewage treatment plant. Sewage pipeline systems exhibit a unique dendritic distribution, with pipe diameters gradually increasing from small to large—a pattern distinctly different from the continuous, circulating characteristics of water supply networks. During operation, sewage primarily flows from higher to lower elevations due to gravity, relying on the difference in water level at both ends of the pipe; the pipes themselves do not experience internal pressure.

[0003] In current sewage pipe installation operations, the conventional procedure is to arrange the pipes to be laid sequentially along one side of the excavated trench. After determining the required pipe length, multiple workers are needed to work together to drag the pipes into the excavated trench and then connect them using heat fusion connectors. However, due to the varying pipe specifications, especially longer or thicker pipes, the friction generated when moving them on the ground is significant, making manual laying and movement extremely difficult. This method significantly reduces the efficiency of sewage pipe laying and can cause some damage to the sewage pipes.

[0004] Therefore, there is an urgent need to develop a sewage pipe laying device suitable for sewage treatment plants to effectively solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings in the above-mentioned background technology and provide a sewage pipe laying device for sewage treatment plants. This device should have the characteristics of convenient installation and high laying efficiency.

[0006] The technical solution of this utility model is:

[0007] A sewage pipe laying device for a sewage treatment plant includes a pipe body; characterized in that: at least two laying moving rings are sleeved on the outside of the pipe body; the inner ring of the laying moving ring is provided with a clamping mechanism for clamping the pipe body; and the outer ring of the laying moving ring is provided with omnidirectional ball wheels for easy dragging.

[0008] The laying moving ring includes a pair of half rings, which are respectively hinged to each other by a first shaft and fixed by a connecting piece; the clamping mechanism is set on the inner arc surface of the half ring, and the universal ball wheel is set on the outer arc surface of the half ring.

[0009] The clamping mechanism includes a limiting seat fixed to the semi-ring, a clamping block disposed on one side of the inner arc surface of the semi-ring and slidably positioned on the limiting seat by a movable block, a threaded rod rotatably positioned on the limiting seat and whose inner end is threadedly connected to the movable block, and a handle fixed to the outer end of the threaded rod.

[0010] The end of the semi-ring is provided with a connecting seat, and both ends of the connecting seat are provided with grooves for installing connectors.

[0011] The connector includes a limiting rod and a nut; one end of the limiting rod is rotatably positioned in the groove of one side connector via a second shaft, and the other end of the limiting rod passes through the groove of the other side connector and engages with the nut.

[0012] The clamping surface of the clamping block is curved in an arc shape.

[0013] The clamping surface of the clamping block is provided with a rubber pad.

[0014] The beneficial effects of this utility model are:

[0015] The water pipe laying process of this utility model is extremely simple. It only requires placing the laying moving ring on the outside of the water pipe body, then turning the handle to make the clamping block clamp the outer wall of the water pipe body. Then, the water pipe body can be dragged at will to move to a suitable position for laying work, which greatly improves the efficiency and quality of laying operations. At the same time, the laying moving ring adopts a splicing structure and can quickly adapt to water pipes of different diameters through an adjustable spacing clamping mechanism, which effectively solves the defects of existing laying methods, significantly improves the versatility and engineering applicability of the device, and provides an efficient and reliable solution for various water pipe laying projects.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a sewage pipe laying device for a sewage treatment plant includes a pipe body 16 and a laying movable ring.

[0026] The laying movement ring is fitted onto the main body of the water pipe, allowing workers to easily move the main body of the water pipe equipped with the laying movement ring to a suitable position for laying work. At least two laying movement rings are fitted onto the outside of the main body of the water pipe, arranged along the axial direction of the main body. The number and spacing of the laying movement rings are adjusted according to the length and weight of the main body of the water pipe. Figure 1 The image shows that a laying movement ring is attached to each end of the main body of the water pipe.

[0027] The inner ring of the laying moving ring is equipped with two symmetrically arranged clamping mechanisms. These clamping mechanisms clamp the outer wall of the water pipe body from both sides, thus fixing the laying moving ring to the water pipe body. The outer ring of the laying moving ring is equipped with several omnidirectional ball wheels 4, which are evenly arranged along the circumference of the laying moving ring. During laying, the water pipe body contacts the ground through the omnidirectional ball wheels, which can significantly reduce the friction between the water pipe body and the ground, making it easier for workers to move the water pipe body to the laying position.

[0028] like Figure 2 , Figure 3As shown, the laying movable ring includes a pair of half-rings 1, one end of each half-ring is rotatably hinged together and the other end is fixed. One end of each half-ring is hinged to a first shaft 2 and the other end is fixed by a connector. Each half-ring has a clamping mechanism on its inner arc surface (the clamping mechanisms of the two half-rings are arranged symmetrically), and each half-ring has four omnidirectional ball wheels on its outer arc surface.

[0029] like Figure 4 As shown, the clamping mechanism includes a limiting seat 9, a movable block 11, a clamping block 12, a threaded rod 13, a handle 14, and a rubber pad 15.

[0030] The limiting seat is installed in the middle of the semi-ring and passes through the inner and outer arc surfaces of the semi-ring. The clamping block is set on one side of the inner arc surface of the semi-ring and is slidably positioned on the limiting seat by the movable block. The limiting seat is provided with a limiting groove 10, the opening of the limiting groove facing the water pipe body. One end of the movable block is slidably positioned in the limiting groove (the movable block can slide along the normal direction of the semi-ring), and the other end of the movable block is fixed to the clamping block.

[0031] The threaded rod is rotatably positioned on the limiting seat. The inner end of the threaded rod (the end closest to the water pipe body) extends into the limiting groove and engages with the movable block threadedly. The inner end of the threaded rod has an external thread, and the movable block has a threaded hole that mates with the threaded rod. The outer end of the threaded rod extends out of the outer arc surface of the semi-circle and is fixed to the handle. The clamping surface of the clamping block is curved in an arc shape, and its shape is adapted to the outer wall shape of the water pipe body for easy clamping. The clamping surface of the clamping block is also provided with a rubber pad to increase friction during clamping.

[0032] Turning the handle moves the clamp closer to or further away from the water pipe body, thus adapting to water pipe bodies of different diameters and ensuring that the laying moving ring can be firmly installed on the water pipe body.

[0033] like Figure 3 As shown, the upper end of the semi-ring is provided with an outwardly extending connecting seat 5, and the front and rear ends of the connecting seat are provided with grooves 7. The connecting piece is placed in the groove to fix the two semi-rings.

[0034] The connector includes a limiting rod 8 and a nut 801. One end of the limiting rod is rotatably mounted in the groove of one half-ring via a second shaft 6. The second shaft is inserted into the groove and is perpendicular to the axis of the water pipe body. The other end of the limiting rod is threaded and passes through the groove of the other half-ring before engaging with the nut. Tightening the nut allows the two half-rings to be combined into a complete laying moving ring.

[0035] Using the above connection method, the laying moving ring can be easily fitted onto the water pipe body, and then the clamping mechanism can be used to fix the laying moving ring to the water pipe body.

[0036] The method of using this utility model is as follows:

[0037] 1. Suspend the main body of the water pipe, put the laying moving ring on the main body of the water pipe in the open state, close the half rings on both sides of the laying moving ring, turn the limiting rod into the groove of the other half ring, and tighten the nut of the connector to lock the end of the half ring.

[0038] 2. Rotate the handle to adjust the position of the clamping blocks so that the clamping blocks on both sides clamp the water pipe body, ensuring that the water pipe body is located in the center of the laying moving ring, so that the laying moving ring is firmly installed on the water pipe body;

[0039] 3. Lower the main body of the water pipe so that the omnidirectional ball wheels of the movable ring contact the ground;

[0040] 4. Push the main body of the water pipe to the laying position, remove the laying moving ring, and then lay the pipe.

[0041] The above are only specific embodiments of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.

[0042] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0043] The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the present invention.
