DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0035] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Please refer to Figures 1 to 3 ,in, Figure 1 Schematic diagram of the structure of the middle partition wall assembly equipment provided in the embodiment of the present application Figure 1 , Figure 2 Schematic diagram of the structure of the middle partition wall assembly equipment provided in the embodiment of the present application Figure 2 , Figure 3 A side view of the moving mechanism provided in an embodiment of the present application.

[0037] In a first specific embodiment, the present application provides a middle partition wall assembly device for assembling middle partition walls, which can maximize the efficiency of middle partition wall construction and reduce construction costs.

[0038] The middle partition wall assembly device mainly includes a moving mechanism 1 and a lifting mechanism 2, and the lifting mechanism 2 is arranged on the moving mechanism 1. Among them, the moving mechanism 1 is used for movement and transfer, and the lifting mechanism 2 is used for lifting and assembly. The present application separates movement and assembly. Unlike the middle partition wall assembly device that integrates movement and assembly functions, the middle partition wall assembly device of the present application has the characteristics of simple structure and convenient fault detection and resolution.

[0039] The moving mechanism 1 is loaded with the pipe segments 011 to be assembled. When the moving mechanism 1 moves, the moving mechanism 1 drives the pipe segments 011 to be assembled and the hoisting mechanism 2 to move. The moving mechanism 1 can be driven by a motor or other means, which also fall within the scope of the description of this embodiment.

[0040] The hoisting mechanism 2 hoists the segment 011 to be assembled on the moving mechanism 1, and then assembles the segment 011 to be assembled. It should be noted that the hoisting position of the hoisting mechanism 2 and the segment 011 to be assembled is offset relative to the center of gravity of the segment 011 to be assembled.

[0041] Reference Figure 1 and Figure 2 , the direction of the x-axis is the first direction (front and back in the length direction), the direction of the y-axis is the second direction (left and right in the width direction), and the direction of the z-axis is the third direction (up and down in the height direction).

[0042] During the use of the partition wall assembly equipment, the pipe segment to be assembled 011 initially lies on the moving mechanism 1; the moving mechanism 1 is used to drive the lifting mechanism 2 and the pipe segment to be assembled 011 to move to the specified position, and the moving mechanism 1 moves along the first direction; the lifting mechanism 2 is used to lift the pipe segment to be assembled 011, and the lifting mechanism 2 lifts the pipe segment to be assembled 011; during lifting, the pipe segment to be assembled 011 moves along the first direction and rises along the third direction; because the lifting position and the center of gravity position are offset in the first direction, when the pipe segment to be assembled 011 rises along the third direction, the pipe segment to be assembled 011 rotates to a vertical state under the action of its own gravity; the lifting mechanism 2 continues to lift the pipe segment to be assembled 011, assembles the pipe segment to be assembled 011 on the bottom block 021, and then sets the top block 022, and after completion, a formed tunnel 012 is formed.

[0043] For example, the hoisting hole of the pipe segment 011 to be assembled, that is, the hoisting position, deviates from the center of gravity by about 100 mm, so as to facilitate rotation and turning by gravity.

[0044] It should be noted that the formed tunnel 012 is the structure after the pipe segments 011 to be assembled are installed. For the sake of convenience, the intermediate partition wall panels mentioned below are equivalent to the pipe segments 011 to be assembled.

[0045] In this embodiment, the middle partition wall assembly equipment: not only can the middle partition wall panel be moved forward and backward along the tunnel direction, and moved up and down along the height direction, but also can realize the one-time forming of the middle partition wall, improve the installation flexibility, and meet the different middle partition wall installation requirements; but also adopts the method of using gravity to turn over, fully utilizes the gravity of the middle partition wall panel itself, reduces the energy consumption of the machine during the installation of the middle partition wall, reduces the cost of using the middle partition wall equipment, and improves the construction efficiency of the middle partition wall in the tunnel.

[0046] It should be noted that the purpose of this application is to maximize the efficiency of middle partition wall construction and reduce construction costs. As for other relevant contents of middle partition wall construction, please refer to the existing technology and will not be repeated here.

[0047] Please refer to Figures 4 to 6 ,in, Figure 4 A top view of the mobile mechanism provided in an embodiment of the present application, Figure 5 This is a structural diagram of a forming tunnel provided in an embodiment of the present application.

[0048] In some embodiments, the mobile mechanism 1 includes an assembly vehicle 101 and a turning roller 102 provided on the assembly vehicle 101 , and the turning roller 102 is used for auxiliary support when the pipe segment 011 to be assembled is lifted.

[0049] In this embodiment, the assembly vehicle 101 carries the other components of the assembly machine and is equipped with a rotating motor that receives instructions from the construction worker and provides mobility for the partition wall assembly equipment. The turning roller 102 is an unpowered rotating cylinder that assists in the turning of the pipe segment 011 to be assembled.

[0050] In some embodiments, the first end of the assembly vehicle 101 is used to load the pipe segment to be assembled 011, and the second end of the assembly vehicle 101 is provided with an opening, and the turning roller 102 is located on one side of the opening so that the pipe segment to be assembled 011 can be transferred from the first end to the second end during lifting, and the pipe segment to be assembled 011 can be slowly rotated in the opening with the assistance of the turning roller 102 until it is vertical.

[0051] In this embodiment, if Figure 1 As shown, the pipe segment to be assembled 011 is lifted from left to right along the first direction on the assembly vehicle 101. While the lifting mechanism 2 drives the pipe segment to be assembled 011 to move above the pipe segment to be assembled 011, the turning roller 102 rotates on the lower side of the pipe segment to be assembled 011 to assist in flipping the pipe segment to be assembled 011.

[0052] To facilitate the installation of the pipe segment 011 to be assembled, the assembly vehicle 101 has a special structural shape, so that the pipe segment 011 to be assembled can be slowly rotated until it is vertical with the assistance of the turning roller 102. At this time, the pipe segment 011 to be assembled is located in the opening at the front end of the assembly vehicle 101, and then the pipe segment 011 to be assembled is further lifted by the lifting mechanism 2 to leave the opening.

[0053] In some embodiments, the hoisting mechanism 2 includes a mounting frame provided on the moving mechanism 1 and a crane 203 installed on the mounting frame, and the crane 203 is used to lift the pipe segments 011 to be assembled.

[0055] In some embodiments, the mounting frame includes a support beam 201 provided on the mobile mechanism 1 and a track beam 202 mounted on the support beam 201 , and the crane 203 is mounted on the track beam 202 .

[0056] In this embodiment, the support beams 201 can be symmetrically installed on both sides of the assembly vehicle 101 to provide support for the track beams 202, the crane 203, etc. The track beams 202 are the tracks of the crane 203 and can be symmetrically installed on the support beams 201 at the top of the assembly vehicle 101 to provide support for the crane 203.

[0057] In some embodiments, the hoisting mechanism 2 further includes a safety device 206 disposed on the track beam 202 .

[0058] In this embodiment, the function of the safety device 206 is to prevent the crane 203 from moving out of the track beam 202 and provide a limiting effect.

[0059] Exemplarily, the support beams 201 are arranged in pairs along the second direction, each support beam 201 is equipped with a track beam 202, the track beams 202 are arranged along the first direction, and each track beam 202 is equipped with a crane 203, which is used to lift the pipe segments to be assembled 011 along the third direction and transport the pipe segments to be assembled 011 along the first direction.

[0060] In this embodiment, the support beams 201 are symmetrically arranged, and the track beams 202 correspond to the support beams 201 one by one. Similarly, the cranes 203 correspond to the track beams 202 one by one.

[0061] In some embodiments, the lifting mechanism 2 also includes a lifting rod 204 and a protective cover 205 installed on the lifting rod 204. The lifting rod 204 is connected to the crane 203. The pipe segment 011 to be assembled has a lifting hole for the lifting rod 204 to pass through. The protective cover 205 is used to position the pipe segment 011 to be assembled.

[0062] In this embodiment, to facilitate the lifting of the segment 011 by the crane 203, the segment 011 is provided with a lifting hole through which a lifting rod 204 can pass. The lifting rod 204 is then connected to the crane 203, thereby enabling the crane 203 to lift the segment 011. A protective cover 205 is symmetrically mounted on the lifting rod 204 and serves to limit the segment 011, preventing the segment 011 from moving axially along the lifting rod 204.

[0063] In some embodiments, the pipe segment 011 to be assembled is provided with a taper pin hole.

[0064] In this embodiment, the bottom of the pipe segment 011 to be assembled is pre-machined with a cone pin hole corresponding to the bottom block 021, so that the pipe segment 011 to be assembled can be docked with the guide cone pin 0211 of the bottom block 021 when it is installed on the bottom block 021.

[0065] In addition, the pipe segments 011 to be assembled and the bottom block 021 may be matched with each other in other ways such as mortise and tenon, which should also fall within the scope of the description of this embodiment.

[0066] It should be noted that the number, length, height and spacing of the track beams 202, the number, height and spacing of the cranes 203, etc. should be adjusted according to actual needs and should fall within the scope of the description of this embodiment.
