Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe jacking construction equipment, and particularly relates to a pipe jacking construction equipment with anti-rotation function. Background Technique
[0002] Pipe jacking construction is a pipeline laying construction technology with little or no excavation. By means of the jacking force generated by the jacking equipment in the working pit, the friction between the pipeline and the surrounding soil is overcome, and the pipeline is jacked into the soil according to the designed gradient, and the soil is transported away. After one section of the pipe is jacked into the soil layer, the second section of the pipe is lowered and the jacking continues. Pipe jacking technology is widely used in the laying, replacement and repair of various pipelines under the conditions where it is not allowed or not feasible to excavate, such as crossing roads, railways, rivers, downtown areas, etc. Due to the advantages of low comprehensive cost, short construction period, small environmental impact, good construction safety, etc., pipe jacking construction technology is widely used in the construction of underground pipelines such as municipal water supply and drainage, communication cables, gas pipelines, and power cables.
[0003] Before the pipe jacking machine is ready to start construction, the tail end of the pipe jacking machine is pushed by the jacking equipment until the cutter head end face of the pipe jacking machine is aligned with the tunneling hole of the pipe jacking construction. Then, the cutter head of the pipe jacking machine is started, and at the same time, the jacking equipment continues to push the tail end of the pipe jacking machine to push the pipe jacking machine into the soil. During the process of the pipe jacking machine excavating and advancing in the hole, due to the large friction between the barrel of the pipe jacking machine and the soil, the pipe jacking machine generally does not rotate and cause deviation. However, when the pipe jacking machine starts to excavate and has not completely entered the soil, there are no other anti-rotation measures for the barrel of the pipe jacking machine. At this time, the pipe jacking machine is very easy to rotate, resulting in excavation deviation or the overturning of the main jacking cylinder.
[0004] Therefore, the prior art needs to be improved. Content of the Utility Model
[0005] The technical problem to be solved by the utility model is that the pipe jacking machine is prone to rotate at the beginning of pipe jacking construction, resulting in excavation deviation or the overturning of the main jacking cylinder. The purpose is to provide a pipe jacking construction equipment with anti-rotation function, adopt corresponding technical means, and has the beneficial effect of preventing the barrel of the pipe jacking machine from rotating at the beginning of excavation, ensuring accurate excavation and guaranteeing normal operation.
[0006] The utility model is realized through the following technical solutions:
[0007] The utility model provides a pipe jacking construction device for preventing rotation, which comprises a slide rail and a tunneling head sliding along the slide rail. An anti-rotation vertical plate is arranged on the outer wall of the barrel body of the tunneling head. The slide rail is provided with a first anti-rotation member for resisting the anti-rotation vertical plate to prevent the tunneling head from rotating forward, and the slide rail is further provided with a second anti-rotation member for resisting the anti-rotation vertical plate to prevent the tunneling head from rotating backward. The first anti-rotation member and the second anti-rotation member are both parallel to the slide rail, and both the first anti-rotation member and the second anti-rotation member extend to the hole of the pipe jacking construction.
[0008] In the above technical solution, the pipe jacking construction device for preventing rotation mainly comprises a slide rail, a tunneling head, an anti-rotation vertical plate, a first anti-rotation member and a second anti-rotation member. The tunneling head slides along the slide rail under the push of the jacking device. Since the anti-rotation vertical plate is fixedly installed on the outer wall of the barrel body of the tunneling head, and the anti-rotation vertical plate is resisted by the first anti-rotation member and the second anti-rotation member. During the sliding process of the tunneling head along the slide rail, the anti-rotation vertical plate also slides along the first anti-rotation member and the second anti-rotation member. Therefore, even if the tunneling head is not completely inserted into the soil, its barrel body will not be affected by the cutter head and rotate during the initial excavation.
[0009] Further, in the utility model, the front end of the anti-rotation vertical plate is configured as a tip, and the thickness of the anti-rotation vertical plate gradually increases from the tip backward.
[0010] Further, in the utility model, the tip is configured as an inclined tip.
[0011] Further, in the utility model, a plurality of the anti-rotation vertical plates are evenly distributed around the barrel body of the tunneling head.
[0012] Further, in the utility model, the anti-rotation vertical plates are arranged at two places on the front side and the rear side of the barrel body of the tunneling head.
[0013] Further, in the utility model, the slide rail comprises a base, the base is provided with a bracket, and a track for supporting the tunneling head is installed at the top of the bracket.
[0014] Further, in the utility model, the base is provided with a support rod for supporting the first anti-rotation member or the second anti-rotation member.
[0015] Further, in the utility model, the first anti-rotation member and the second anti-rotation member are configured as I-beams.
[0016] Further, in the utility model, a curved panel connected to the tunneling head is arranged at the bottom of the anti-rotation vertical plate. An installation groove adapted to the curved panel is arranged on the outer wall of the barrel body of the tunneling head, and the curved panel is connected to the tunneling head by screws.
[0017] Further, in the present utility model, neither the first anti-rotation member nor the second anti-rotation member contacts the tunneling head.
[0018] Compared with the prior art, the present utility model has the following advantages and beneficial effects:
[0019] The anti-rotation pipe jacking construction equipment provided by the present utility model mainly includes a slide rail, a tunneling head, an anti-rotation vertical plate, a first anti-rotation member, and a second anti-rotation member. The tunneling head slides along the slide rail under the push of the jacking equipment. Since the anti-rotation vertical plate is fixedly installed on the outer wall of the barrel body of the tunneling head and is resisted by the first anti-rotation member and the second anti-rotation member. During the sliding process of the tunneling head along the slide rail, the anti-rotation vertical plate also slides along the first anti-rotation member and the second anti-rotation member. Therefore, even if the tunneling head does not completely enter the soil, its barrel body will not be affected by the cutter head and rotate during the initial excavation, and thus the problem of excavation deviation caused by rotation will not occur, nor will the main jacking cylinder be overturned, ensuring accurate excavation and normal construction. When the anti-rotation vertical plate slides out of the first anti-rotation member and the second anti-rotation member, the tunneling head completely enters the soil. At this time, the anti-rotation vertical plate also inserts into the soil to offset the reaction torque of the cutter head rotating and excavating, preventing the barrel body of the tunneling head from rotating in the soil, and the use effect is better.

[0028] Embodiment
[0029] This embodiment provides a pipe jacking construction device for preventing rotation, as Figures 1-4 shown, and the specific structure is described as follows.
[0030] Please refer to Figure 1 and Figure 2 shown. The pipe jacking construction device for preventing rotation in the embodiments of the present utility model mainly includes five parts: a slide rail 1, a tunneling head 2, an anti-rotation vertical plate 3, a first anti-rotation member 4, and a second anti-rotation member 5. Among them, the slide rail 1 provides a moving path for the tunneling head 2 during the initial excavation, the tunneling head 2 is used to excavate soil, and the anti-rotation vertical plate 3, the first anti-rotation member 4, and the second anti-rotation member 5 cooperate with each other to prevent the barrel body of the tunneling head 2 from rotating during the initial excavation.
[0031] Furthermore, as Figure 1 、 Figure 2As shown, the sliding rail 1 mainly consists of three parts: a base 101, a bracket 102, and a track 103. The base 101 is made of sleepers, which are evenly laid on the bottom surface of the pipe jacking construction pit. The bracket 102 is a vertical metal rod, and the track 103 is a horizontal metal pipe. Two parallel tracks 103 are aligned with the tunneling hole at the top of the construction. The top end of the bracket 102 is fixedly connected to the bottom of the track 103, and the bottom end of the bracket 102 is fixedly connected to the base 101. Since the tunneling head 2 is a cylinder, the tunneling head 2 is placed on the track 103, and the rear end of the barrel of the tunneling head 2 is pushed forward by the jacking equipment at the rear side.
[0032] Furthermore, in combination with Figure 1 and Figure 2 As shown, the strut 104 is made of a metal rod. The bottom end of the strut 104 is fixedly connected to the base 101. Multiple struts 104 are distributed on the left and right sides of the track 103. The first anti-rotation member 4 and the second anti-rotation member 5 are both made of I-beam bars. The first anti-rotation member 4 is fixedly connected to the left strut 104, and the second anti-rotation member 5 is fixedly connected to the right strut 104. The first anti-rotation member 4 and the second anti-rotation member 5 are parallel to the extending direction of the sliding rail 1.
[0033] It should be noted that after the tunneling head 2 is placed on the sliding rail 1, the first anti-rotation member 4 and the second anti-rotation member 5 do not contact the outer wall of the tunneling head 2, so as to avoid the friction effect of the first anti-rotation member 4 and the second anti-rotation member 5 on the outer wall of the tunneling head 2.
[0034] In some embodiments of this embodiment, as Figure 1 and Figure 2 shown, the tunneling head 2 includes two parts: a cutter head at the front side and a barrel at the rear side. The anti-rotation vertical plate 3 is made of cemented carbide material and is fixedly installed on the outer wall of the barrel of the tunneling head 2. In this embodiment, six anti-rotation vertical plates 3 are installed, with three in each group evenly distributed around the barrel of the tunneling head 2. The two groups of anti-rotation vertical plates 3 are respectively installed at the front side and the rear side of the barrel of the tunneling head 2. As Figure 4 shown, when the front half of the tunneling head 2 enters the soil, the rear half is still on the sliding rail 1, playing a good anti-rotation role. The two groups of anti-rotation vertical plates 3 can resist greater rotational forces, making the forces on the front and rear sides of the barrel of the tunneling head 2 tend to be balanced, and making the anti-rotation effect of the tunneling head 2 better.
[0035] As Figure 1As shown, after the tunneling head 2 is placed on the slide rail 1, the first anti-rotation member 4 on the left resists the bottom surface of the anti-rotation vertical plate 3 on the left, and the second anti-rotation member 5 on the right resists the bottom surface of the anti-rotation vertical plate 3 on the right. The first anti-rotation member 4 can prevent the barrel of the tunneling head 2 from rotating counterclockwise (forward rotation), and the second anti-rotation member 5 can prevent the barrel of the tunneling head 2 from rotating clockwise (reverse rotation), thereby preventing the barrel of the tunneling head 2 from rotating.
[0036] In some embodiments of the present embodiment, in combination with Figure 2 and Figure 3 As shown, the front side of the anti-rotation vertical plate 3 is a relatively narrow tip 301. The tip 301 is convenient for the tunneling head 2 to break through the soil when advancing, reducing the influence of the anti-rotation vertical plate 3 on excavation. The thickness of the anti-rotation vertical plate 3 gradually increases from front to back to increase the thickness and prevent the anti-rotation vertical plate 3 from being deformed easily due to insufficient stiffness.
[0037] Furthermore, the tip 301 adopts an inclined tip 301, and the inclined tip 301 gradually inclines backward from bottom to top, making it easier to break through the soil.
[0038] In combination with Figure 2 and Figure 3 As shown, the curved panel 302 is fixed to the bottom surface of the anti-rotation vertical plate 3, and the anti-rotation vertical plate 3 and the curved panel 302 are integrally formed. An installation groove is formed on the outer wall of the barrel of the tunneling head 2. The curved panel 302 and the installation groove have the same size and shape, so that the curved panel 302 is integrally embedded in the installation groove, and then the curved panel 302 and the barrel of the tunneling head 2 are fixedly connected by screws.
[0039] The working principle of the pipe jacking construction equipment with anti-rotation of the present utility model is as follows:
[0040] During the process of the tunneling head 2 sliding along the slide rail 1, the anti-rotation vertical plate 3 also slides along the first anti-rotation member 4 and the second anti-rotation member 5. Therefore, even if the tunneling head 2 is not completely inserted into the soil, its barrel will not be affected by the cutter head and rotate during the initial excavation, and thus the problem of excavation deviation caused by rotation will not occur, nor will the main jack cylinder be overturned, ensuring accurate excavation and normal construction.
[0041] In summary, the present utility model provides a pipe jacking construction device that prevents rotation, which includes a slide rail 1 and a tunneling head 2 that slides along the slide rail 1. An anti-rotation vertical plate 3 is provided on the outer wall of the barrel of the tunneling head 2. The slide rail 1 is provided with a first anti-rotation member 4 that resists the anti-rotation vertical plate 3 to prevent the tunneling head 2 from rotating forward, and the slide rail 1 is further provided with a second anti-rotation member 5 that resists the anti-rotation vertical plate 3 to prevent the tunneling head 2 from rotating backward. The first anti-rotation member 4 and the second anti-rotation member 5 are both parallel to the slide rail 1, and both the first anti-rotation member 4 and the second anti-rotation member 5 extend to the opening of the pipe jacking construction. The front end of the anti-rotation vertical plate 3 is configured as a tip 301, and the thickness of the anti-rotation vertical plate 3 gradually increases from the tip 301 backward. The tip 301 is configured as an inclined tip 301. A plurality of anti-rotation vertical plates 3 are evenly distributed around the barrel of the tunneling head 2. The anti-rotation vertical plates 3 are provided at two places on the front side and the rear side of the barrel of the tunneling head 2. The slide rail 1 includes a base 101, the base 101 is provided with a bracket 102, and a track 103 for supporting the tunneling head 2 is installed at the top of the bracket 102. The base 101 is provided with a support rod 104 for supporting the first anti-rotation member 4 or the second anti-rotation member 5. The first anti-rotation member 4 and the second anti-rotation member 5 are configured as I-beams. The bottom of the anti-rotation vertical plate 3 is provided with a curved panel 302 connected to the tunneling head 2, and an installation groove adapted to the curved panel 302 is provided on the outer wall of the barrel of the tunneling head 2. The curved panel 302 is screwed to the tunneling head 2. The first anti-rotation member 4 and the second anti-rotation member 5 do not contact the tunneling head 2. Therefore, the pipe jacking construction device that prevents rotation provided by the present utility model has the beneficial effect of preventing the barrel of the pipe jacking machine from rotating during the initial excavation, ensuring accurate excavation, and ensuring normal operation.
