Description

Technical Field

[0001] This utility model relates to the field of tunnel boring machine technology, specifically to a rapid insertion mechanism for the cutting teeth of a tunnel boring machine cutter. Background Technology

[0002] A tunnel boring machine (TBM) is a specialized piece of equipment for tunnel construction that integrates excavation, support, and muck removal functions. It is widely used in tunnel projects such as subways, railways, highways, municipal works, and hydropower projects. It supports the surrounding rock through the shield shell and segments, and uses the rotating cutterhead to cut the soil while simultaneously expelling the cut soil from the tunnel, thus achieving continuous tunnel excavation. The cutting teeth are the core working components of the TBM cutterhead, which directly contact the rock and soil to complete the cutting and crushing tasks. Their performance directly affects the tunneling efficiency, cutter life, and construction cost of the TBM.

[0003] After long-term use, the cutting teeth of tunnel boring machines inevitably wear down and need to be replaced. The current method of replacing tunnel boring machine cutting tools requires workers to manually disassemble and install multiple parts, which is cumbersome and time-consuming, and is not conducive to improving work efficiency. At the same time, workers need to rely on experience to position the cutting teeth, which can easily lead to errors in the installation of the cutting tools and affect the subsequent use.

[0004] To address this, a rapid insertion mechanism for the cutting teeth of a tunnel boring machine cutter is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid insertion mechanism for the cutting teeth of a tunnel boring machine cutter in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A rapid insertion mechanism for cutting teeth of a tunnel boring machine (TBM) includes a mounting frame and a cutter body. The mounting frame has a fixed axis groove on its surface. An mounting sleeve is fixedly installed on the inner wall surface of the mounting frame. The inner wall surface of the mounting frame is provided with an elastic compression mechanism. The number of elastic compression mechanisms is four and they are symmetrically arranged vertically and horizontally. The number of mounting sleeves is the same as the number of elastic compression mechanisms. The surface of the mounting sleeve is provided with a fixing component for fixing the elastic compression mechanism. The surface of the mounting frame is provided with a lifting mechanism, and the surface of the lifting mechanism is provided with a stop bar.

[0008] Furthermore, the dimensions of the fixed-axis groove are adapted to the specifications of the tool body.

[0009] Furthermore, the elastic compression mechanism includes a mounting block, which is fixedly mounted on the inner wall surface of the mounting frame. A slide rod is slidably mounted on the surface of the mounting block. The slide rod is slidably disposed relative to the inner wall surface of the mounting sleeve. A compression plate is fixedly mounted on the end surface of the slide rod away from the mounting sleeve. A spring is fixedly connected between the compression plate and the opposite surface of the mounting block. The spring is sleeved on the outside of the slide rod.

[0010] Furthermore, an inclined plate is fixedly installed on the surface of the extrusion plate.

[0011] Furthermore, the fixing component includes a mounting plate, which is fixedly installed on the inner wall surface of the mounting frame. There are two mounting plates, which are symmetrically arranged about the front and back of the mounting sleeve. Bolts are threaded into the surface of the mounting plate. Fixing holes are opened on the surface of the mounting sleeve. Insertion holes are opened on the surface of the slide rod. The specifications of the bolts are compatible with the fixing holes and insertion holes.

[0012] Furthermore, the lifting mechanism includes a top plate, which is fixedly installed on the top surface of the mounting frame. A bottom plate is fixedly installed on the surface of the mounting frame. There are two top plates and two bottom plates, arranged side to side. A motor is fixedly installed on the top surface of one side of the top plate. A threaded rod is fixedly connected to the output end of the motor. The threaded rod is rotatably installed between the opposite surfaces of the top plate and the bottom plate. A guide rod is fixedly installed between the opposite surfaces of the top plate and the bottom plate on the other side. A stop rod is threadedly fitted onto the surface of the threaded rod and slidably fitted onto the surface of the guide rod.

[0013] The beneficial effects of this utility model are as follows: When the cutter body needs to be inlaid, the cutter body is pushed into the inner wall surface of the fixed axis groove. The cutter body pushes the elastic extrusion mechanism to both sides. The elastic extrusion mechanism slides along the inner wall surface of the mounting sleeve and extrudes the cutter body through elastic force. The mounting sleeve and the elastic extrusion mechanism are fixed by the fixing component. The lifting mechanism drives the stop bar to rise and fall, so that the stop bar blocks the cutter body from one side, making the installation of the cutter body more stable. It eliminates the need for workers to manually disassemble and install multiple parts, making the positioning more accurate and facilitating the rapid inlay of the shield machine cutter cutting teeth. This is beneficial to improving work efficiency and subsequent use effect. Attached Figure Description

[0023] like Figures 1 to 3As shown, a rapid insertion mechanism for cutting teeth of a tunnel boring machine includes a mounting frame 1 and a cutter body 8. The surface of the mounting frame 1 is provided with a fixed axis groove 2. An mounting sleeve 3 is fixedly installed on the inner wall surface of the mounting frame 1. An elastic compression mechanism 4 is provided on the inner wall surface of the mounting frame 1. The number of elastic compression mechanisms 4 is four and they are symmetrically arranged in a vertical and horizontal manner. The number of mounting sleeves 3 is the same as the number of elastic compression mechanisms 4. The surface of the mounting sleeve 3 is provided with a fixing component 5 for fixing the elastic compression mechanism 4. The surface of the mounting frame 1 is provided with a lifting mechanism 6, and the surface of the lifting mechanism 6 is provided with a stop bar 7.

[0024] Specifically, when the cutter body 8 needs to be inlaid, the cutter body 8 is pushed into the inner wall surface of the fixed axis groove 2. The cutter body 8 contacts the elastic extrusion mechanism 4 and pushes the elastic extrusion mechanism 4 to both sides. The elastic extrusion mechanism 4 slides along the inner wall surface of the mounting sleeve 3 and extrudes the cutter body 8 through elastic force. The mounting sleeve 3 and the elastic extrusion mechanism 4 are fixed by the fixing component 5. The lifting mechanism 6 drives the stop bar 7 to rise and fall, so that the stop bar 7 blocks the cutter body 8 from one side, making the installation of the cutter body 8 more stable. It eliminates the need for workers to manually disassemble and install multiple parts, making the positioning more accurate and facilitating the rapid inlay of the shield machine cutter cutting teeth, which is conducive to improving work efficiency and subsequent use effect.

[0025] like Figures 1 to 3 As shown, the dimensions of the fixed-axis groove 2 are compatible with the specifications of the tool body 8.

[0026] Specifically, the dimensions of the fixed-axis groove 2 are adapted to the specifications of the tool body 8, making the installation of the tool body 8 more stable.

[0027] like Figures 1 to 2 As shown, the elastic compression mechanism 4 includes a mounting block 401, which is fixedly mounted on the inner wall surface of the mounting frame 1. A slide rod 402 is slidably mounted on the surface of the mounting block 401. The slide rod 402 is slidably disposed relative to the inner wall surface of the mounting sleeve 3. A compression plate 403 is fixedly mounted on the end surface of the slide rod 402 away from the mounting sleeve 3. A spring 404 is fixedly connected between the opposing surfaces of the compression plate 403 and the mounting block 401. The spring 404 is sleeved on the outside of the slide rod 402.

[0028] Specifically, when the tool body 8 moves toward the surface of the fixed axis groove 2, the tool body 8 first contacts the extrusion plate 403 and pushes the extrusion plates 403 on both sides to the sides. At the same time, the slide rod 402 slides along the inner wall surface of the mounting block 401 and the mounting sleeve 3, and the spring 404 is compressed and deformed. The reaction force of the spring 404 is used to compress and fix the tool body 8, making the positioning of the tool body 8 more convenient and accurate, which is conducive to improving work efficiency.

[0029] like Figures 1 to 2 As shown, an inclined plate is fixedly installed on the surface of the extrusion plate 403.

[0030] Specifically, the inclined plate provides a guide when the tool body 8 contacts the extrusion plate 403, making the insertion of the tool body 8 more convenient and improving work efficiency.

[0031] like Figures 1 to 2 As shown, the fixing component 5 includes a mounting plate 501, which is fixedly installed on the inner wall surface of the mounting bracket 1. There are two mounting plates 501, which are symmetrically arranged about the front and rear of the mounting sleeve 3. Bolts 504 are threaded into the surface of the mounting plate 501. The surface of the mounting sleeve 3 is provided with fixing holes 502, and the surface of the slide rod 402 is provided with insertion holes 503. The bolts 504 are compatible with the specifications of the fixing holes 502 and the insertion holes 503.

[0032] Specifically, once the installation position of the tool body 8 is determined, the insertion hole 503 on the surface of the slide bar 402 is aligned with the fixing hole 502 on the surface of the mounting sleeve 3. The bolts 504 on the surface of the mounting plate 501 are rotated and inserted into the inner wall surfaces of the fixing hole 502 and the insertion hole 503 to fix the mounting sleeve 3 and the slide bar 402. This makes the compression and fixation of the tool body 8 by the elastic compression mechanism 4 more stable, which is beneficial to the stability of subsequent use.

[0033] like Figure 1 and Figure 3 As shown, the lifting mechanism 6 includes a top plate 601, which is fixedly installed on the top surface of the mounting frame 1. A bottom plate 602 is fixedly installed on the surface of the mounting frame 1. There are two top plates 601 and two bottom plates 602, which are arranged left and right. A motor 603 is fixedly installed on the top surface of one top plate 601. A threaded rod 604 is fixedly connected to the output end of the motor 603. The threaded rod 604 is rotatably installed between the opposite surfaces of the top plate 601 and the bottom plate 602. A guide rod 605 is fixedly installed between the opposite surfaces of the top plate 601 and the bottom plate 602 on the other side. A stop rod 7 is threadedly fitted onto the surface of the threaded rod 604 and slidably fitted onto the surface of the guide rod 605.

[0034] Specifically, the output end of the motor 603 rotates to drive the threaded rod 604 to rotate, thereby causing the stop rod 7, which is threaded onto the surface of the threaded rod 604 and slidably mounted on the surface of the guide rod 605, to rise and fall. This allows the stop rod 7 to block and limit the tool body 8 from one side, making the installation and use of the tool body 8 safer. It eliminates the need for workers to disassemble and install multiple parts, which is beneficial to improving work efficiency.

[0035] In summary: When the cutter body 8 needs to be inlaid, the cutter body 8 is pushed into the inner wall surface of the fixed axis groove 2. The cutter body 8 pushes the elastic extrusion mechanism 4 to both sides. The elastic extrusion mechanism 4 slides along the inner wall surface of the mounting sleeve 3 and extrudes the cutter body 8 through elastic force. The mounting sleeve 3 and the elastic extrusion mechanism 4 are fixed by the fixing component 5. The lifting mechanism 6 drives the stop bar 7 to rise and fall, so that the stop bar 7 blocks the cutter body 8 from one side, making the installation of the cutter body 8 more stable. It eliminates the need for workers to manually disassemble and install multiple parts, making the positioning more accurate and facilitating the rapid inlay of the shield machine cutter cutting teeth. This is beneficial to improving work efficiency and subsequent use.
