Description

Technical Field

[0001] This utility model relates to the field of pipe jacking construction technology, specifically to a reinforcement structure for preventing deviation during pipe jacking construction in railway engineering. Background Technology

[0002] Pipe jacking is a challenging and relatively unknown engineering project. Trenchless engineering technology has completely solved the problems of damage to urban buildings and traffic congestion during pipeline laying. It also demonstrates its advantages in stabilizing soil layers and protecting the environment. This is very important for cities with busy traffic, dense populations, numerous surface buildings, and complex underground pipelines. It will create a clean, comfortable, and beautiful environment for the city.

[0003] Pipe jacking construction requires the use of a pipe jacking machine to jack the pipe. However, when using the pipe, it is usually connected to the shaft and propulsion equipment through a lifting device. In this step, the suspended pipe is prone to swaying and deviation, which can lead to inaccurate connection. To address this, we propose a reinforcement structure to prevent deviation in pipe jacking construction for rail engineering. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement structure for preventing deviation during pipe jacking construction in railway engineering, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a reinforcement structure for preventing deviation during pipe jacking construction in railway engineering, comprising a first limiting member, one end of the first limiting member being connected to a second limiting member via a first support member, both ends of the second limiting member being fitted with slidable sliders, each of the two sets of sliders being rotatably connected to three sets of rotating rods, the opposite ends of the two sets of sliders being adjusted by an adjustment component, and the second limiting member having a groove corresponding to the adjustment component.

[0006] Preferably, the adjusting assembly includes a first connecting rod, a second connecting rod, and a first hydraulic rod. Each of the two sets of sliders is hinged to one of the first connecting rods on opposite sides. The other end of the first connecting rod is hinged to the second connecting rod. The second connecting rod is connected to the output end of the first hydraulic rod. The first hydraulic rod is installed on one side of the first limiting member.

[0007] Preferably, each of the two sets of sliders has three sets of springs installed at opposite ends to assist in resetting the sliders.

[0008] Preferably, the top end of the rotating rod is rotatably connected to the limiting block, which can limit the position of the rotating rod.

[0009] Preferably, the inner cavity of the first limiting member is equipped with four sets of second hydraulic rods, and the output end of the second hydraulic rods is connected to a second support member.

[0010] Preferably, a positioning rail is provided on the side of the second limiting member away from the first limiting member, and the positioning rail can be used to support the pipeline.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model can drive two sets of sliders to slide along the inner cavity of the second limiting member through the adjustment component, and the distance between the two sets of sliders can be adjusted. With the help of the rotating rod, the pipe can be clamped and limited. The rotating rod can rotate, and the pipe will not be affected during the clamping and anti-deviation process. Compared with the prior art, it can limit and prevent the deviation of the hoisted pipe, and make it more convenient to accurately dock with wells and propulsion equipment.

[0013] 2. This utility model utilizes the extension of the first hydraulic rod to push the second connecting rod, which in turn pushes the first connecting rod, thus widening the distance between the two sets of sliders and compressing the spring. Conversely, the retraction of the first hydraulic rod reduces the distance between the two sets of sliders, and with the spring resetting, the adjustment process becomes smoother. The installed limiting block limits the rotating rod, and in conjunction with the slider, prevents the rotating rod from shifting, thereby preventing the clamped pipe from shifting. The extension of the second hydraulic rod pushes the second support member, which in turn pushes the pipe placed on the positioning track into the well. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1

[0020] Please refer to Figure 1-3 As shown, this utility model provides a reinforcement structure for preventing deviation during pipe jacking construction in track engineering, including a first limiting member 1. One end of the first limiting member 1 is connected to a second limiting member 3 via a first support member 2. Sliding sliders 4 are installed at both ends of the second limiting member 3. Each of the two sets of sliders 4 is rotatably connected to three sets of rotating rods 5. The distance between the opposite ends of the two sets of sliders 4 is adjusted by an adjustment component. The second limiting member 3 is provided with a groove 7 corresponding to the adjustment component.

[0021] In this embodiment, the two sets of sliders 4 can be driven to slide along the inner cavity of the second limiting member by the adjusting component, and the distance between the two sets of sliders 4 can be adjusted. With the help of the rotating rod 5, the pipe 14 can be clamped and limited. The rotating rod 5 can rotate, and the insertion of the pipe 14 will not be affected during the clamping and anti-deviation process. Compared with the prior art, the hoisted pipe 14 can be limited and anti-deviation is prevented, which makes it more convenient to dock with wells and propulsion equipment.

[0022] Please refer to Figure 1-3 As shown, the adjustment assembly includes a first connecting rod 8, a second connecting rod 9, and a first hydraulic rod 10. Each of the two sets of sliders 4 is hinged to one side of the opposite side of the first connecting rod 8. The other end of the first connecting rod 8 is hinged to the second connecting rod 9. The second connecting rod 9 is connected to the output end of the first hydraulic rod 10. The first hydraulic rod 10 is installed on one side of the first limiting member 1. Each of the two sets of sliders 4 has three sets of springs 6 installed at the opposite ends of the two sets of sliders 4, which can assist the sliders 4 in resetting. The top end of the rotating rod 5 is rotatably connected to the limiting block 15, which can limit the rotation of the rotating rod 5.

[0023] In this embodiment, both the first hydraulic rod 10 and the second hydraulic rod 11 are hydraulically assisted by a hydraulic pump in the prior art. By extending the first hydraulic rod 10, the second connecting rod 9 can be pushed, which in turn pushes the first connecting rod 8, thereby widening the distance between the two sets of sliders 4 and compressing the spring 6. Conversely, the retraction of the first hydraulic rod 10 can narrow the distance between the two sets of sliders 4 and, with the spring 6 resetting, make the adjustment process smoother. The installed limiting block 15 limits the rotating rod 5, and with the slider 4, the rotating rod 5 is not easily deviated, thus making it less likely for the clamped pipe 14 to deviate.

[0024] Please refer to Figure 1-3As shown, four sets of second hydraulic rods 11 are installed in the inner cavity of the first limiting member 1. The output end of the second hydraulic rod 11 is connected to the second support member 12. A positioning rail 13 is provided on the side of the second limiting member 3 away from the first limiting member 1. The positioning rail 13 can be used to support the pipe 14.

[0025] In this embodiment, the extension of the second hydraulic rod 11 can push the second support member 12, causing it to push the pipe 14 placed on the positioning rail 13 into the well.

[0026] Working principle: First, by extending the first hydraulic rod 10, the second connecting rod 9 can be pushed, which in turn pushes the first connecting rod 8, widening the gap between the two sets of sliders 4 and compressing the spring 6. Conversely, the retraction of the first hydraulic rod 10 can narrow the gap between the two sets of sliders 4 and, in conjunction with the spring 6, make the adjustment process smoother. The installed limiting block 15 limits the rotating rod 5, which, in conjunction with the slider 4, makes it difficult for the rotating rod 5 to deviate, thus making it difficult for the clamped pipe 14 to deviate. By extending the second hydraulic rod 11, the second support member 12 can be pushed, which in turn pushes the pipe 14 placed on the positioning rail 13 into the well.
