Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically to a large-diameter reinforced concrete pipe jacking construction device. Background Technology

[0002] With the progress of urbanization, the pipe jacking construction technology of municipal engineering has been gradually applied. It has shifted the traditional construction from above ground to underground, achieving the goal of short construction cycle and no high working cost without affecting ground activities. At the same time, underground work means that the interference with traffic order during construction is greatly reduced. However, when dealing with large-diameter reinforced concrete pipes, due to the large diameter and heavy weight of the pipes, the stability of the concrete pipes for support and advancement is even more important to avoid pipe breakage.

[0003] However, existing large-diameter reinforced concrete pipe jacking construction equipment still has the following defects during use:

[0004] 1. Existing concrete pipe jacking construction equipment cannot flexibly adapt to pipes of different diameters when supporting pipes. Moreover, when supporting pipes, the support is always placed inside the pipe. Therefore, under the weight of the pipe, the stress point of the pipe support is located above the pipe, resulting in a small stress area and making it prone to cracking under the weight of the pipe.

[0005] 2. After the pipeline is supported, jacks are needed to push it forward at the construction point. In order to ensure that the pipeline is evenly stressed during the push, the jacks need to be evenly distributed. However, when dealing with pipelines of different diameters, adjusting the position of the jacks is cumbersome and reduces the efficiency of construction. Utility Model Content

[0006] The purpose of this utility model is to solve the problems mentioned above, such as the inability to flexibly adapt to pipes of different diameters, small stress area, easy breakage under the weight of the pipe, and cumbersome adjustment of the jack position when dealing with pipes of different diameters, which reduces construction efficiency. This utility model provides a large-diameter reinforced concrete pipe jacking construction device.

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A large-diameter reinforced concrete pipe jacking construction device includes a body, an operating rod fixedly installed at the center of the rear end of the body, hydraulic jacks uniformly and slidably connected inside the body, mounting seats fixedly installed on the outer sides of the middle of each hydraulic jack, sliders slidably connected to the inner sides of each mounting seat inside the body, cross rods drivingly connected between the sliders and the mounting seats on both sides, a rotating shaft rotatably connected at the center of the body, threads on the outer periphery of the upper and lower sides of the body, and a support assembly on the front side of the body, on which a pipe is placed.

[0009] Furthermore, the rear ends of all the sliders and the front ends of the sliders on the left and right sides are fixedly connected to limit posts, and the sliders are limited and slidably connected inside the machine body through the limit posts.

[0010] Furthermore, one end of the cross rod is hinged to the inner side of the mounting base, and the other end extends to both sides and is hinged to both sides of the slider located on the inner side between the mounting bases, so that when the slider moves in extension and retraction, the mounting base and the hydraulic jack can move in extension and retraction synchronously through the cross rod.

[0011] Furthermore, the rotating shaft passes through the upper and lower sliders, and the threads on the upper and lower sides of the rotating shaft are threadedly connected to the sliders. Moreover, the threads on the upper and lower sides have opposite patterns. Therefore, when the rotating shaft rotates, it can drive the upper and lower sliders to move towards each other or away from each other.

[0012] Furthermore, an internal hexagon block is fixedly connected to the top of the shaft, which facilitates the rotation of the shaft by cooperating with a hexagonal wrench.

[0013] Furthermore, the support assembly includes support columns, with support columns fixedly connected to the front ends of the upper and lower sliders, and connecting rods fixedly connected to the front ends of the support columns. A horizontal plate is fixedly connected to the ends of the connecting rods that are far apart from each other, and rotating rollers are rotatably connected to the left and right sides of the front ends of the horizontal plate.

[0014] Furthermore, the upper roller supports the pipe from above the inner side of the pipe, while the lower roller supports the pipe from below the outer side of the pipe. Therefore, it is possible to support both the top and bottom of the pipe simultaneously.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model, through the cooperation of the support component, slider and rotating shaft, can adjust the position of the support component by driving the rotation of the rotating shaft, thus making it suitable for pipes of different diameters. At the same time, when supporting, it can support both the top and bottom of the pipe, so that the force on the pipe is more even and the pipe is prevented from breaking due to its own weight.

[0017] 2. This utility model, through the action of the cross rod between the slider and the mounting base of the hydraulic jack, can simultaneously adjust the position of the hydraulic jack when driving the slider to move to adapt the support component to pipes of different diameters, so that the evenly distributed hydraulic jacks are aligned with the pipe wall, eliminating the need for subsequent adjustments, making operation more convenient and improving construction efficiency.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0028] A preferred embodiment of the present invention, a large-diameter reinforced concrete pipe jacking construction device, will be described in detail below, such as... Figures 1-7As shown, a large-diameter reinforced concrete pipe jacking construction device includes a body 1. An operating rod 2 is fixedly installed at the center of the rear end of the body 1. Hydraulic jacks 3 are uniformly and slidably connected inside the body 1. Mounting seats 4 are fixedly installed on the outer side of the middle part of the hydraulic jacks 3. Sliding blocks 5 are slidably connected at the inner side of the mounting seats 4 inside the body 1. Limiting posts 51 are fixedly connected to the rear end of all sliding blocks 5 and the front end of the left and right sliding blocks 5. The sliding blocks 5 are slidably connected inside the body 1 by the limiting posts 51.

[0029] Both sides of the slider 5 are connected to the mounting base 4 by cross rods 6. One end of the cross rod 6 is hinged to the inner side of the mounting base 4, and the other end is extended to both sides and hinged to the two sides of the slider 5 located on the inner side of the mounting base 4. This allows the mounting base 4 and the hydraulic jack 3 to move synchronously when the slider 5 moves in extension and retraction.

[0030] A rotating shaft 7 is rotatably connected to the center of the body 1. An internal hexagon block 71 is fixedly connected to the top of the rotating shaft 7, so that the rotating shaft 7 can be driven to rotate by the cooperation of a hexagonal wrench and the internal hexagon block 71.

[0031] The upper and lower sides of the machine body 1 are provided with threads 8. The rotating shaft 7 passes through the upper and lower sliders 5. The threads 8 on the upper and lower sides of the rotating shaft 7 are threadedly connected to the sliders 5. The threads 8 on the upper and lower sides are opposite. Therefore, when the rotating shaft 7 rotates, it can drive the upper and lower sliders 5 to move towards each other or away from each other. A support component 9 is provided on the front side of the machine body 1. A pipe 10 is placed on the support component 9.

[0032] Furthermore, such as Figure 1 , Figure 6 , Figure 8 As shown, the support assembly 9 includes a support column 91. The front ends of the upper and lower sliders 5 are fixedly connected to the support column 91. The front ends of the support column 91 are fixedly connected to the connecting rods 92. The ends of the connecting rods 92 that are far apart from each other are fixedly connected to the horizontal plate 93. The left and right sides of the front end of the horizontal plate 93 are rotatably connected to the rollers 94.

[0033] The upper roller 94 supports the pipe 10 from above the inner side of the pipe 10, and the lower roller 94 supports the pipe 10 from below the outer side of the pipe 10. Therefore, it can support both the top and bottom of the pipe 10 at the same time.

[0034] The working principle of this utility model is as follows:

[0035] When large-diameter reinforced concrete pipe jacking is required, the rotating shaft 7 is driven to rotate by using the internal hexagon block 71 on the upper part of the machine body 1, according to the size of the pipe 10. During the rotation of the rotating shaft 7, the upper and lower sliding blocks 5 are connected by threads on the upper and lower sides of the rotating shaft 7, and the threads on the upper and lower sides of the rotating shaft 7 are opposite, which allows the upper and lower sliding blocks 5 to move towards or away from each other. In turn, the sliding blocks 5 drive the support components 9 to move towards or away from each other synchronously, so as to adjust the distance between the upper and lower rotating rollers 94 according to the size of the pipe 10.

[0036] After adjusting the distance between the upper and lower rotating rollers 94, the rotating rollers 94 are used to support the pipe 10. When supporting, the upper rotating roller 94 is located above the inner side of the pipe 10 and below the outer side of the pipe 10, so that the top and bottom of the pipe 10 can be supported, making the force on the pipe 10 more even when supported, and preventing the pipe 10 from breaking due to its own weight. The rotation of the rotating rollers 94 makes it easy to rotate and adjust the pipe 10.

[0037] After the support of pipe 10 is completed, pipe 10 is moved to the construction position by operating lever 2. When adjusting the support assembly 9 by driving the upper and lower sliders 5 to move towards or away from each other, the sliding blocks 5 on both sides move towards or away from each other. During this process, the cross rods 6 between all the sliders 5 and the mounting base 4 can also drive the mounting base 4 to move towards or away from each other synchronously. This, in turn, drives the hydraulic jacks 3 to move towards or away from each other. Due to the initial position design of the hydraulic jacks 3 and the rotating roller 94, when the position of the rotating roller 94 is adjusted according to the diameter of pipe 10, the evenly distributed hydraulic jacks 3 can also be aligned with the pipe wall of pipe 10. Therefore, while adjusting the support assembly 9 according to the diameter of pipe 10, the position of the hydraulic jacks 3 can also be adjusted to align the hydraulic jacks 3 with the pipe wall of pipe 10, making the advancement of pipe 10 more convenient and improving construction efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
