Description

A mobile device for green construction of tunnel boring machines Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically a mobile device for green construction of tunnel boring machines. Background Technology

[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, is a specialized engineering machine for tunnel excavation. Modern TBMs integrate optics, mechanics, electronics, hydraulics, sensing, and information technology, and have functions such as excavating and cutting soil, transporting excavated material, assembling tunnel lining, and measuring and guiding. They involve multiple disciplines such as geology, civil engineering, mechanics, hydraulics, electrical engineering, control, and surveying. Moreover, they must be designed and manufactured in a "tailor-made" manner according to different geological conditions, and the reliability requirements are extremely high. TBMs are widely used in tunnel projects such as subways, railways, highways, municipal works, and hydropower projects.

[0003] Currently, when transporting and using tunnel boring machines (TBMs), the overall movement and fixation of the equipment are inconvenient. During the journey, the uneven road surface can easily cause the TBM to be bumped, which can easily damage its internal components. Furthermore, the traditional tunneling method is relatively simple and has low tunneling efficiency. Therefore, a green construction mobile device for TBMs is needed to improve the above problems. Summary of the Invention

[0004] To address the current challenges of transporting and securing tunnel boring machines (TBMs), including the inconvenience of moving and fixing the equipment, the susceptibility to bumps and vibrations caused by uneven road surfaces, which can damage internal components, and the relatively simple and inefficient traditional tunneling methods, this invention aims to provide a mobile device for green construction of TBMs to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A mobile device for green construction of a tunnel boring machine includes a main body, a mobile support component at the bottom of the main body, and a tunneling component on the main body.

[0007] The mobile support assembly includes a combination plate, which is installed at the bottom of the main body. A hydraulic cylinder is installed at the bottom of the combination plate, and the output end of the hydraulic cylinder is fixedly connected to a foot. The bottom of the combination plate is equipped with casters.

[0008] The tunneling assembly includes a base frame, which is mounted on the main body. A motor is mounted on the top of the base frame, and a lead screw is fixedly connected to the output end of the motor. A threaded block is threadedly connected to the lead screw, and a support plate is fixedly connected to the top of the threaded block. A bracket is fixedly connected to the top of the support plate, and the tunnel boring machine body is installed inside the bracket.

[0009] As a preferred embodiment of this utility model, the composite plate is made of ACF artificial cartilage material.

[0010] As a preferred embodiment of this utility model, the movable support assembly is provided in four sets.

[0011] As a preferred embodiment of this utility model, a slide rail is fixedly connected to the top of the base frame, and a slider is slidably connected to the top of the slide rail, with the slider being fixedly connected to the support plate.

[0012] As a preferred embodiment of this utility model, there are two slide rails, which are symmetrically distributed on both sides of the lead screw. There are two sliders on each slide rail, and four sliders are distributed at the four corners of the support plate.

[0013] As a preferred embodiment of this utility model, a bearing seat is fixedly connected to the top of the base frame, and the lead screw extends into the interior of the bearing seat.

[0014] As a preferred embodiment of this utility model, the main body includes a base plate, a protective box is fixedly connected to the top of the base plate, and a power supply is fixedly connected inside the protective box.

[0015] As a preferred embodiment of this utility model, a control box is fixedly connected inside the protective box, and a start button is provided on the side of the control box.

[0018] 1. In this utility model, the shield machine can be moved and fixed in both directions by using the foot and the moving wheel, which improves the flexibility of the shield machine. When it is necessary to fix the shield machine, the internal hydraulic support rod is raised and lowered by the drive of the hydraulic cylinder, so that the foot contacts the ground and the moving wheel leaves the ground, thereby realizing the stable tunneling work of the shield machine.

[0019] 2. In this utility model, the composite plate of ACF artificial cartilage material has extremely high energy absorption capacity, which can absorb a large amount of impact energy and effectively reduce the bumps and vibrations experienced by the tunnel boring machine on rough roads. Compared with traditional rubber shock absorbers, the composite plate has better energy absorption performance.

[0020] 3. In this utility model, by using the forward and reverse driving method of the motor, the threaded block moves on the lead screw, thereby driving the shield machine body on the top of the support plate to extend or retract.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1-4 for a mobile device for green construction of a tunnel boring machine, which includes a main body 1, a mobile support component 2 at the bottom of the main body 1, and a tunneling component 3 on the main body 1;

[0028] In this embodiment, referring to Figures 1, 2 and 3, the movable support assembly 2 includes a combination plate 201, which is installed at the bottom of the main body 1. A hydraulic cylinder 202 is installed at the bottom of the combination plate 201, and a foot 203 is fixedly connected to the output end of the hydraulic cylinder 202. A movable wheel 204 is provided at the bottom of the combination plate 201.

[0029] The tunneling assembly 3 includes a base frame 301, which is mounted on the main body 1. A motor 302 is mounted on the top of the base frame 301. A lead screw 303 is fixedly connected to the output end of the motor 302. A threaded block 305 is threadedly connected to the lead screw 303. A support plate 307 is fixedly connected to the top of the threaded block 305. A bracket 308 is fixedly connected to the top of the support plate 307. The tunnel boring machine body 309 is installed inside the bracket 308.

[0030] The shield machine body 309 can be moved and fixed in both directions using the foot 203 and the moving wheel 204, which improves the flexibility of the shield machine. When it is necessary to fix the shield machine body 309, the internal hydraulic support rod is raised and lowered by the hydraulic cylinder 202, so that the foot 203 contacts the ground. At this time, the moving wheel 204 leaves the ground, thus enabling the shield machine body 309 to carry out stable tunneling. The composite plate 201 has extremely high energy absorption capacity and can absorb a large amount of impact energy, effectively reducing the bumps and vibrations experienced by the shield machine on rough roads. Compared with traditional rubber shock absorbers, the composite plate 201 made of ACF artificial cartilage material has better energy absorption performance.

[0031] The movable support assembly 2 is provided with four sets. The top of the base frame 301 is fixedly connected to the slide rail 310, and the top of the slide rail 310 is slidably connected to the slider 306. The slider 306 is fixedly connected to the support plate 307. There are two slide rails 310, and the two slide rails 310 are symmetrically distributed on both sides of the lead screw 303. There are two sliders 306 on the slide rail 310. The four sliders 306 are distributed at the four corners of the support plate 307. The top of the base frame 301 is fixedly connected to the bearing seat 304, and the lead screw 303 extends into the interior of the bearing seat 304.

[0032] By using the forward and reverse drive of the motor 302, the threaded block 305 moves on the lead screw 303, thereby driving the shield machine body 309 on the top of the support plate 307 to extend or retract. In conjunction with the slider 306, the shield machine body 309 on the top of the support plate 307 slides on the slide rail 310, which can achieve high-efficiency work while improving the stability of tunneling work.

[0033] In this embodiment, referring to Figures 1 and 4, the main body 1 includes a base plate 101, a protective box 102 is fixedly connected to the top of the base plate 101, a power supply 103 is fixedly connected inside the protective box 102, the movable support assembly 2 and the tunneling assembly 3 are both mounted on the base plate 101, a control box 104 is fixedly connected inside the protective box 102, a start button 106 is provided on the side of the control box 104, a display screen 105 is fixedly connected to the side of the control box 104, and one or more physical buttons 107 are provided on the side of the control box 104.

[0034] The protective box 102 can protect the shield machine body 309 from external dust and rain, extending the service life of the shield machine body 309. The start button 106 and physical button 107 are used to control the electrical control devices in the moving support assembly 2 and the tunneling assembly 3.

[0035] In this solution, a mobile device for green construction of a tunnel boring machine (TBM) utilizes the mobile wheels 204 to move the TBM loading components to the designated location. During movement, the combined plate 201 reduces vibration damage to the TBM body 309 caused by uneven road surfaces. When the TBM needs to be fixed, the internal hydraulic support rod is raised and lowered by the hydraulic cylinder 202, causing the foot 203 to contact the ground. At this time, the mobile wheels 204 leave the ground, thus enabling stable tunneling operation of the TBM. During tunneling, the threaded block 305 moves on the lead screw 303, driven by the motor 302, which in turn drives the TBM body 309 on top of the support plate 307 to extend for tunneling. Simultaneously, the slider 306 slides the TBM body 309 on top of the support plate 307 along the slide rail 310, ensuring stability and improving tunneling efficiency.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
