Technical Field
[0001] This application relates to the field of tunneling machines, and more particularly to an installation device for a copper bushing of a tunneling machine. Background Technology
[0002] A tunneling machine (TBM) is a mechanical device used to excavate tunnels beneath flat ground, primarily for construction in underground spaces such as coal mines and tunnels. TBMs directly break up ore and rock through the axial pressure and rotational force of their cutting tools, achieving the purpose of creating tunnels or shafts. TBMs offer advantages such as continuous excavation, high speed, minimal damage to the surrounding rock, and improved working environment. Copper bushings are installed on the steel structures of the TBM, including the blades, frame, rotary table, and rear support.
[0003] The utility model patent with announcement number CN211916671U proposes a copper sleeve removal and installation device for a tunneling machine, including a removal and installation base for abutting the copper sleeve, a connecting rod connected to the removal and installation base, and a sliding rod for slidingly connecting a sliding hammer; one end of the sliding rod is detachably connected to the connecting rod, the other end of the sliding rod is fixed with a handle, and the end of the connecting rod away from the sliding rod is connected to the removal and installation base through a pin.
[0004] The aforementioned tunneling machine copper sleeve installer installs the copper sleeve by pushing a sliding hammer to move on a sliding rod. However, each tunneling machine has such copper sleeves, and they are mass-produced. It is quite laborious for the operator to push the copper sleeve into the machine body by moving the sliding hammer for a long time, which reduces work efficiency. Utility Model Content
[0005] To address the aforementioned problems, this application provides an installation device for a copper bushing of a tunneling machine.
[0006] The installation device for a copper bushing of a tunneling machine provided in this application adopts the following technical solution:
[0007] An installation device for a tunneling machine copper sleeve includes a copper sleeve body and an installation assembly for installing the copper sleeve body onto the machine body. The installation assembly includes a pad, a hydraulic cylinder is installed on one side wall of the pad, the output end of the hydraulic cylinder passes through the pad and is fixedly connected to a first threaded rod, a stop plate for pushing the copper sleeve body is threaded onto the first threaded rod, and a clamping assembly for fixing the machine body is provided on the pad.
[0008] By adopting the above technical solution, during use, the pad is attached to the machine body, the first threaded rod passes through the machine body, and then the copper sleeve body is fitted onto the first threaded rod, aligning the copper sleeve body with the machine body. Next, the abutment plate is threaded onto the first threaded rod, positioning the abutment plate on one side of the copper sleeve body. By activating the hydraulic cylinder, the first threaded rod is pulled, causing the abutment plate to move and push the copper sleeve body onto the machine body. This minimizes the need for prolonged use of a sliding hammer to hammer the copper sleeve into the machine body, which is laborious for the operator and reduces work efficiency.
[0009] Preferably, the clamping assembly includes two fixing blocks fixedly connected to the outer wall of the pad, and each fixing block has a second threaded rod rotatably connected to one side wall, and each second threaded rod has a clamping block for clamping the machine body threadedly connected to it.
[0010] By adopting the above technical solution, after the pad is attached to the machine body, the clamping block is positioned on the other side of the machine body. Then, by rotating the second threaded rod, the clamping block is moved on the second threaded rod and brought closer to the machine body, so that the machine body is connected to the pad and the machine body is prevented from shaking.
[0011] Preferably, a guide rod is fixedly connected to one side wall of the fixing block on the side of the second threaded rod, the clamping blocks are respectively sleeved on the guide rod, and a limit block is fixedly connected to the end of the guide rod away from the fixing block.
[0012] By adopting the above technical solution, the guide rod can prevent the clamping block from rotating with the second threaded rod when the second threaded rod rotates, and the limiting block can prevent the clamping block from falling off.
[0013] Preferably, each of the sidewalls of the fixing block away from the second threaded rod is provided with a sprocket, the sprockets are fixedly connected to the second threaded rod respectively, and a chain is installed on the two sprockets.
[0014] By adopting the above technical solution, the sprocket and chain allow the other sprocket to rotate synchronously when one sprocket is rotated, thus causing the two second threaded rods to rotate simultaneously, improving operational convenience.
[0015] Preferably, a toothed ring is fitted onto the cylinder, and an annular groove is formed on the inner wall of the toothed ring. An annular slider is fixedly connected to the side wall of the cylinder, and the annular slider is slidably disposed in the annular groove. The toothed ring is located inside the chain and meshes with the chain.
[0016] By adopting the above technical solution, the toothed ring can prevent the chain from contacting the hydraulic cylinder, thus avoiding friction between the chain and the hydraulic cylinder during chain rotation and preventing wear between the chain and the hydraulic cylinder.
[0017] Preferably, a mounting plate is fixedly connected to the end of the hydraulic cylinder away from the first threaded rod, and a plurality of third threaded rods are fixedly connected to the side wall of the mounting plate away from the hydraulic cylinder, and each of the third threaded rods is threaded with a nut.
[0018] By adopting the above technical solution, the cylinder can be easily fixed by passing the third threaded rod through the external mounting bracket and then installing the nut.
[0019] Preferably, a rubber pad for improving clamping stability is fixedly connected to one side wall of the clamping block.
[0020] By adopting the above technical solution, when the clamping block clamps the machine body, the rubber pad abuts against the machine body, which can improve the stability of clamping the machine body.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. This application utilizes the cooperative arrangement of structures such as a hydraulic cylinder, a first threaded rod, and a stop plate. In use, the pad is placed against the machine body, allowing the first threaded rod to pass through the machine body. Then, the copper sleeve body is fitted onto the first threaded rod, aligning the copper sleeve body with the machine body. Next, the stop plate is threaded onto the first threaded rod, positioning the stop plate on one side of the copper sleeve body. By activating the hydraulic cylinder, the first threaded rod is pulled, causing the stop plate to move and push the copper sleeve body onto the machine body. This minimizes the need for prolonged use of a sliding hammer to hammer the copper sleeve into the machine body, which is laborious for the operator and reduces work efficiency.
[0023] 2. After attaching the pad to the machine body, position the clamping block on the other side of the machine body. Then rotate one of the sprockets to make the chain drive the other sprocket to rotate, which can make the two second threaded rods rotate at the same time. This will cause the clamping block to move on the second threaded rods and get closer to the machine body, so that the machine body is connected to the pad and the machine body is prevented from shaking.

Detailed Implementation
[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0030] This application discloses an installation device for a copper bushing of a tunneling machine.
[0031] Reference Figure 1 , Figure 2 and Figure 3 An installation device for a tunneling machine copper bushing includes a copper bushing body 1 and an installation assembly for installing the copper bushing body 1 onto the machine body. The installation assembly includes a pad 2, a hydraulic cylinder 3, a first threaded rod 4, and a stop plate 5.
[0032] One side wall of the pad 2 is attached to the machine body, and the oil cylinder 3 is installed on the other side wall of the pad 2. The output end of the oil cylinder 3 passes through the pad 2 and is fixedly connected to the first threaded rod 4. The copper sleeve body 1 is sleeved on the first threaded rod 4 and located on one side of the machine body. The abutment 5 is threaded to the first threaded rod 4 to push the copper sleeve body 1 into the machine body. The pad 2 is provided with a clamping assembly for fixing the machine body.
[0033] Reference Figure 1 and Figure 2 The clamping assembly includes two fixing blocks 6 fixedly connected to the outer side wall of the pad 2. Each fixing block 6 has a second threaded rod 7 rotatably connected to one side wall. Each second threaded rod 7 has a clamping block 8 threadedly connected to it for clamping the machine body. After the pad 2 is attached to the machine body, the clamping block 8 is positioned on the other side of the machine body. Then, by rotating the second threaded rod 7, the clamping block 8 moves on the second threaded rod 7 and approaches the machine body, so that the machine body is connected to the pad 2 and the machine body is prevented from shaking.
[0034] Reference Figure 2 and Figure 3 One side wall of the fixed block 6 is fixedly connected to a guide rod 9 on one side of the second threaded rod 7. The clamping blocks 8 are respectively sleeved on the guide rod 9. The end of the guide rod 9 away from the fixed block 6 is fixedly connected to a limit block 17. The guide rod 9 can prevent the clamping blocks 8 from rotating with the second threaded rod 7 when the second threaded rod 7 rotates. At the same time, the limit block 17 can prevent the clamping blocks 8 from falling off.
[0035] Reference Figure 1 and Figure 2Each of the fixed blocks 6 has a sprocket 10 on the side wall away from the second threaded rod 7. The sprockets 10 are fixedly connected to the second threaded rod 7. A chain 11 is installed on the two sprockets 10. A rotating disk is fixedly connected to one side wall of one of the sprockets 10. By rotating one of the sprockets 10 through the sprockets 10 and the chain 11, the other sprocket 10 can be rotated synchronously through the rotating disk, so that the two second threaded rods 7 can be rotated at the same time, improving the ease of operation.
[0036] Reference Figure 1 , Figure 2 and Figure 4 A toothed ring 12 is fitted on the cylinder 3. An annular groove 18 is formed on the inner wall of the toothed ring 12. An annular slider 19 is fixedly connected to the side wall of the cylinder 3. The annular slider 19 is slidably disposed in the annular groove 18. The toothed ring 12 is located inside the chain 11 and meshes with the chain 11. The toothed ring 12 can prevent the chain 11 from contacting the cylinder 3 and avoid friction on the cylinder 3 when the chain 11 rotates, which would cause wear between the chain 11 and the cylinder 3.
[0037] Reference Figure 1 The end of the hydraulic cylinder 3 away from the first threaded rod 4 is fixedly connected to a mounting plate 13. Multiple third threaded rods 14 are fixedly connected to the side wall of the mounting plate 13 away from the hydraulic cylinder 3. Nuts 15 are threaded onto each of the third threaded rods 14. By passing the third threaded rods 14 through the external mounting bracket and then installing the nuts 15, the hydraulic cylinder 3 can be easily fixed.
[0038] Reference Figure 4 A rubber pad 16 is fixedly connected to one side wall of the clamping block 8 to improve clamping stability. When the clamping block 8 clamps the machine body, the rubber pad 16 abuts against the machine body, which can improve the stability of clamping the machine body.
[0039] The implementation principle of the installation device for a tunneling machine copper sleeve in this embodiment is as follows: In use, firstly, the third threaded rod 14 is passed through the external mounting bracket, and then the nut 15 is installed to fix the hydraulic cylinder 3. Then, the pad 2 is fitted against the machine body, so that the clamping block 8 is located on the other side of the machine body. Then, one of the sprockets 10 is rotated by a rotating disc, causing the chain 11 to drive the other sprocket 10 to rotate, causing both second threaded rods 7 to rotate simultaneously. This causes the clamping block 8 to move along the second threaded rods 7, closer to the machine body, connecting the machine body with the pad 2 and preventing the machine body from... The machine is shaken, and then the first threaded rod 4 is passed through the machine body. The copper sleeve body 1 is then fitted onto the first threaded rod 4, aligning the copper sleeve body 1 with the machine body. Then, the abutment plate 5 is threaded onto the first threaded rod 4, positioning the abutment plate 5 on one side of the copper sleeve body 1. By starting the hydraulic cylinder 3, the first threaded rod 4 is pulled, causing the abutment plate 5 to move and push the copper sleeve body 1, thus installing the copper sleeve body 1 onto the machine body. This method avoids the problem of prolonged use of a sliding hammer to knock the copper sleeve into the machine body, which is more strenuous for the operator and reduces work efficiency.
[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
