DETAILED DESCRIPTION

[0045] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, not all the embodiments.

[0049] A tunnel boring machine is a mechanical device used for tunneling. It can cut, dig or drill holes in underground tunnels to create a required space or passage. The cutterhead is a key component of a tunnel boring machine. The rock breaking and excavation of the cutterhead mainly comes from the cutters loaded on the cutterhead. During the tunneling process of the tunnel boring machine, due to wear and other reasons, the cutters need to be replaced, and the new and old cutters need to be transported when replacing.

[0050] In the prior art, a tool transporting beam and a hand chain hoist are usually used to transport the tool. The hand chain hoist is first slidably arranged on the tool transporting beam, and then the tool is hoisted by manually pulling the hand chain hoist, and the hand chain hoist is slid along the tool transporting beam to complete the transportation of the tool.

[0051] However, due to the limited space and lifting points for tool transportation, it is not convenient to arrange the tool transportation beam throughout the process of tool transportation, which makes the tool transportation consume a lot of time, reduces the tool change efficiency, and thus affects the construction period.

[0052] In view of this, the tool transportation device provided by the present application is provided with a track assembly, and the track assembly includes two parallel guide rails so that the transportation assembly can move through the guide rails, and the transportation assembly is used to carry the tool. Thus, the transportation assembly realizes transporting the tool to the bottom of the lifting assembly through the guide rails. In order to lift and move the tool to the cutter disc near the tunnel boring machine for tool replacement, the lifting assembly includes a tool transport beam and a lifting member. The tool transport beam is arranged behind the cutter disc of the tunnel boring machine, and the lifting member is slidably connected to the tool transport beam. After the lifting member lifts the tool, the lifting member is pulled to make the lifting member slide on the tool transport beam. Thus, the transportation assembly carries the tool and moves on the guide rails to realize transporting the tool to the bottom of the lifting assembly, and lifts and moves the tool to the cutter disc near the tunnel boring machine through the lifting assembly for tool replacement. This solves the problem that due to limited tool transportation space and lifting points, it is inconvenient to arrange the tool transport beam throughout the process for tool transportation, which consumes a lot of time for tool transportation, reduces tool change efficiency, and thus affects the construction period.

[0053] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] Figure 1 A schematic diagram of the structure of a tool transport device provided in an embodiment of the present application; Figure 2 for Figure 1 A schematic diagram of the structure of the middle track assembly; Figure 3 for Figure 1 Schematic diagram of the structure of the middle lifting assembly; Figure 4 for Figure 1 Schematic diagram of the structure of the transport component; Figure 5 for Figure 4 Section view of section AA in the figure.

[0055] See also Figures 1 to 5 A tool transport device provided in the present application includes a track assembly 100, a transport assembly 200 and a lifting assembly 300. The track assembly 100 includes two parallel guide rails 110, and the two guide rails 110 are used to be fixedly installed at the bottom of the shield of the tunnel boring machine; the transport assembly 200 is used to carry the tool 400 of the tunnel boring machine, and the transport assembly 200 moves relative to the guide rails 110 to transport the tool 400 to the bottom of the lifting assembly 300; the lifting assembly 300 includes a tool transport beam 310 and a lifting member 320. The tool transport beam 310 is used to be installed on the tunnel boring machine through a connecting beam and is located behind the cutter head of the tunnel boring machine. The lifting member 320 is slidably connected to the tool transport beam 310, and the lifting member 320 is raised and lowered relative to the tool transport beam 310 to lift and move the tool 400.

[0056] It is understandable that during the tunneling process of the tunnel boring machine, the cutting tool needs to be replaced due to wear and other reasons. When replacing, the old and new cutting tools need to be transported. Due to the limited lifting points in the tunnel boring machine, a track assembly 100 is provided in the present application. The track assembly 100 includes two parallel guide rails 110. The two guide rails 110 are used to be fixedly installed at the bottom of the shield of the tunnel boring machine. Then, a transport assembly 200 is slidably provided on the guide rails 110. The transport assembly 200 is used to carry the cutting tool 400 of the tunnel boring machine. With such a design, the transport assembly 200 realizes the transportation of the cutting tool 400 through the guide rails 110, and can transport the cutting tool 400 quickly and accurately, saving transportation time. At the same time, it avoids the uncertainty and danger of manual operation and ensures the safety of the operation.

[0057] Among them, in order to lift the tool 400 and move it to the cutterhead near the tunnel boring machine to realize the replacement of the tool 400, a lifting assembly 300 is arranged behind the cutterhead of the tunnel boring machine. The lifting assembly 300 includes a tool transport beam 310 and a lifting part 320. The tool transport beam 310 is installed on the tunnel boring machine. It can be understood that the tool transport beam 310 is usually reliably connected to the belt conveyor on the tunnel boring machine through a connecting beam, so as to ensure the stability of the tool transport beam 310. The lifting member 320 is slidably connected to the tool transporting beam 310, that is, the lifting member 320 can be raised and lowered relative to the tool transporting beam 310, and can also slide on the tool transporting beam 310. Therefore, when the tool 400 is transported to the bottom of the lifting member 300 through the transport component 200, the staff controls the lifting member 320 to descend, and after hooking the tool 400, the staff controls the lifting member 320 to rise, and then pulls the lifting member 320 to drive the tool 400 to move relative to the tool transporting beam 310, and moves the tool 400 to the cutter disc near the tunnel boring machine for replacement, which is convenient for the staff to operate and improves the tool changing efficiency.

[0058] It is understandable that the transportation process of the disassembled old tool 400 is the opposite, that is, the old tool 400 is first lowered and moved to the front side of the track assembly 100 through the lifting assembly 300, and then the old tool 400 is placed on the transportation assembly 200 and transported through the track assembly 100.

[0059] In some embodiments, the lifting member 320 is a lifting tool such as a hand chain hoist or a pneumatic hoist, and its purpose is to achieve the lifting of the tool 400, which is not limited in this embodiment.

[0060] In the present application, by setting a guide rail 110 and a transport assembly 200 slidably set on the guide rail 110 at the bottom of the shield of the tunnel boring machine, the problem of limited lifting points in the tunnel boring machine, which leads to the traditional tool transportation method, that is, the tool transportation beam is not convenient to be arranged throughout the whole process for tool transportation, resulting in inconvenience in tool transportation and excessive time consumption, is solved. After the tool 400 is transported to the bottom of the lifting assembly 300, the tool 400 is lifted and moved by the lifting assembly 300, and the tool 400 is moved to the cutter disc near the tunnel boring machine for replacement, which is convenient for the staff to operate and improves the tool change efficiency. At the same time, the track assembly 100 and the lifting assembly 300 are staggered to avoid the problem of insufficient space in the tool transportation channel. Therefore, the tool 400 is transported by the track assembly 100, the transport assembly 200 and the lifting assembly 300, which saves transportation time, improves the tool change efficiency, and thus shortens the construction period. In addition, the tool transport device provided in the present application integrates a track assembly 100, a transport assembly 200 and a lifting assembly 300, and the spatial arrangement can be diversified to adapt to different transport spaces, and has universality and convenience.

[0061] See also Figure 1 , Figure 2 , Figure 4 and Figure 5 In the embodiment of the present application, the transport assembly 200 includes a base 210 and at least two rollers 220 mounted on the base 210 . The rollers 220 are rollingly arranged on the base 210 , and the rollers 220 are correspondingly slidably connected to the guide rails 110 .

[0062] In some embodiments, in order to carry the tool 400 of the tunnel boring machine, the transport assembly 200 is provided with a base 210, and when transporting the tool 400, the tool 400 is placed on the base 210. In specific implementation, a weight-reducing hole can be provided on the base 210 to reduce the weight of the base 210 and facilitate the handling and operation of the transport assembly 200.

[0063] Among them, at least two rollers 220 are rotatably arranged on the base 210, and at least two rollers 220 are respectively arranged on two opposite sides of the base 210. Such a design can achieve better support and balance effects, while ensuring that the base 210 is more stable when bearing a load, thereby improving the stability and reliability of the transport assembly 200. At the same time, the rollers 220 are correspondingly slidably connected to the guide rails 110, thereby facilitating the transportation of the tool 400 and saving transportation time.

[0064] It is understandable that the roller 220 may be a V-shaped wheel, an H-shaped wheel or the like, the purpose of which is to achieve a sliding connection between the roller 220 and the guide rail 110 so that the transport assembly 200 can transport the tool 400, which is not limited in this embodiment.

[0065] See also Figure 4 and Figure 5In the embodiment of the present application, the transport component 200 also includes a first connection part 230, at least two first connection parts 230 are respectively arranged on opposite sides of the base 210, and the first connection part 230 is installed on the side of the base 210 facing the guide rail 110 through the first connection member 500; the roller 220 is arranged in a one-to-one correspondence with the first connection part 230, and the roller 220 is installed in the first connection part 230 through the fixed shaft 240.

[0066] In the present application, the first connection part 230 and the roller 220 are arranged in a one-to-one correspondence, and the first connection part 230 is used to roll the roller 220 on the base 210, so that the first connection part 230 is fixedly installed on the side of the base 210 facing the guide rail 110 through the first connection member 500, and then the roller 220 is inserted into the first connection part 230. In order to achieve the connection between the roller 220 and the first connection part 230, after the roller 220 is inserted into the first connection part 230, the fixed shaft 240 is inserted from the side of the first connection part 230 away from the base 210, and then penetrates the roller 220, so as to achieve the installation of the roller 220 in the first connection part 230.

[0067] It can be understood that the number and layout of the first connecting members 500 and the first connecting portions 230 are only given for illustrative purposes, and can be specifically configured according to actual needs, and are not limited in this embodiment.

[0068] See also Figure 4 and Figure 5 In the embodiment of the present application, the fixed shaft 240 is plugged into the first connecting portion 230, and a second connecting portion 250 is provided at one end of the fixed shaft 240 away from the base 210. The second connecting portion 250 is fixedly connected to a side of the first connecting portion 230 away from the base 210 through a second connecting member 600 to fix the fixed shaft 240 in the first connecting portion 230.

[0069] In a specific implementation, a second connection part 250 is fixedly connected to one end of the fixed shaft 240 away from the base 210, and the second connection part 250 contacts a side of the first connection part 230 away from the base 210, and the first connection part 230 and the second connection part 250 are fixedly connected via a second connection member 600. Thus, the fixed shaft 240 is fixed in the first connection part 230 via the fixed connection between the second connection part 250 and the first connection part 230.

[0070] It can be understood that the number and layout of the second connecting members 600 are only given for illustrative purposes, and can be specifically configured according to actual needs, and this embodiment is not limited thereto.

[0071] See also Figure 4 and Figure 5In the embodiment of the present application, the transport component 200 further includes at least two bearings 260 , the inner ring of the bearing 260 is correspondingly sleeved on the fixed shaft 240 , and the roller 220 is correspondingly sleeved on the outer ring of the bearing 260 .

[0072] In some embodiments, in order to achieve the rolling of the roller 220 relative to the first connecting part 230 so that the transport component 200 can slide on the guide rail 110, the transport component 200 is provided with a bearing 260, and the inner ring of the roller 220 is correspondingly mounted on the outer ring of the bearing 260, and the inner ring of the bearing 260 is correspondingly mounted on the fixed shaft 240. Therefore, by setting the bearing 260, the roller 220 can roll more smoothly, so that the rotation between the roller 220 and the fixed shaft 240 can be more stable.

[0073] See also Figure 4 and Figure 5 In the embodiment of the present application, the fixed shaft 240 is provided with an oil injection channel 241 and a lubrication channel 242 connected to the oil injection channel 241 , and the lubrication channel 242 is connected to the bearing 260 to provide lubrication oil to the bearing 260 .

[0074] Furthermore, an oil injection channel 241 and a lubrication channel 242 are provided on the fixed shaft 240. The oil injection channel 241 is used to inject lubricating oil into the lubrication channel 242, and the lubrication channel 242 is connected to the bearing 260 to provide a continuous supply of lubricating oil to the bearing 260. In actual use, the staff can add lubricating oil to the lubrication channel 242 through the oil injection channel 241. Since the lubrication channel 242 is connected to the bearing 260, the lubricating oil can be evenly distributed between the rolling element and the inner and outer rings of the bearing 260 to form an oil film, thereby effectively reducing friction and wear, improving rotation accuracy and mechanical efficiency, extending the service life of the bearing 260, and preventing the bearing 260 from rusting, thereby ensuring the convenience and safety of the transport component 200 during use.

[0075] It is understandable that when the lubricating oil needs to be replaced or replenished, the staff only needs to add new lubricating oil to the lubrication channel 242 through the oil filling channel 241, which makes maintenance more convenient. After injecting the lubricating oil into the oil filling channel 241, the opening of the oil filling channel 241 is sealed with a plug to prevent the lubricating oil from leaking through the oil filling channel 241 during use.

[0076] See also Figure 4 In the embodiment of the present application, a placement groove 211 is provided on the base 210 , and the placement groove 211 is used to fix the tool 400 .

[0077] In the present application, a seating groove 211 is provided on the base 210, and the tool 400 is placed on the base 210, and part of the tool 400 is inserted into the seating groove 211, so that the seating groove 211 fixes the tool 400. Therefore, during transportation, the tool 400 can be prevented from detaching from the base 210 and falling, causing the tool 400 to be bumped and damaged.

[0078] It is understandable that the shape and layout of the mounting groove 211 are only given for example, with the purpose of fixing the tool 400, and this embodiment is not limited thereto.

[0079] See also Figure 1 , Figure 2 and Figure 4 In the embodiment of the present application, the transport component 200 further includes a traction member 270 , which is fixedly connected to the base 210 , and the traction member 270 is used to pull the transport component 200 to slide on the guide rail 110 .

[0080] In specific implementation, in order to facilitate the staff to pull the transport component 200, improve the transport efficiency of the transport component 200, and save the knife transportation time, a traction member 270 is fixedly connected to the base 210, and the traction direction of the traction member 270 is the extension direction of the guide rail 110. Therefore, the staff can pull the transport component 200 to slide on the guide rail 110 through the traction member 270, which improves the convenience of using the transport component 200 and saves the knife transportation time.

[0081] In some embodiments, the traction member 270 may be a chain, or other components, the purpose of which is to facilitate the staff to pull the transport assembly 200, and this embodiment is not limited here.

[0082] See also Figure 1 and Figure 2 In the embodiment of the present application, the track assembly 100 also includes a plurality of first support beams 120 and a plurality of second support beams 130, the two ends of the first support beams 120 are respectively fixedly connected to the bottom of the two guide rails 110; one end of the second support beam 130 is fixedly connected to the guide rail 110, and the other end is used to be fixedly connected to the bottom of the shield of the tunnel boring machine.

[0083] In a specific implementation, in order to improve the load-bearing capacity and service life of the guide rail 110 and ensure the use stability of the guide rail 110 , the track assembly 100 further includes a first support beam 120 and a second support beam 130 .

[0084] Among them, the two ends of the first support beam 120 are respectively fixedly connected to two parallel guide rails 110, and in order to ensure the smooth sliding of the transport component 200 on the guide rails 110 and prevent the sliding of the transport component 200 from being hindered, the first support beam 120 is fixedly connected to the bottom of the guide rails 110. By setting the first support beam 120, the stability between the two guide rails 110 can be improved, ensuring the normal operation of the transport component 200 on the guide rails 110.

[0085] At the same time, in order to improve the connection stability between the guide rail 110 and the bottom of the shield of the tunnel boring machine, a second support beam 130 is arranged between the guide rail 110 and the bottom of the shield of the tunnel boring machine. The guide rail 110 is further supported by the second support beam 130, thereby improving the structural stability of the guide rail 110.

[0086] It can be understood that the number and layout of the first support beams 120 and the second support beams 130 are only given for example, and can be specifically set according to actual needs, and this embodiment is not limited here.

[0087] See also Figure 1 and Figure 3 In the embodiment of the present application, the lifting assembly 300 also includes a sliding member 330, and the sliding member 330 is slidably connected to the knife beam 310 at one end facing the knife beam 310, and the sliding member 330 is fixedly connected to the lifting member 320 at one end away from the knife beam 310. The sliding member 330 drives the lifting member 320 to slide relative to the knife beam 310.

[0088] Among them, in order to realize the sliding connection between the lifting member 320 and the tool transporting beam 310, a sliding member 330 is installed at one end of the lifting member 320 close to the tool transporting beam 310, and the sliding member 330 is slidingly connected to the tool transporting beam 310 at one end facing the tool transporting beam 310. With such a design, the lifting member 320 can slide relative to the tool transporting beam 310 through the sliding of the sliding member 330, so that the lifting member 320 can adjust its position as needed to realize the transportation of the tool 400.

[0089] In summary, the tool transport device provided by the present application is provided with a track assembly 100, and the track assembly 100 includes two parallel guide rails 110, so that the transport assembly 200 moves through the guide rails 110, and the transport assembly 200 is used to carry the tool 400. Therefore, the transport assembly 200 transports the tool 400 to the bottom of the lifting assembly 300 through the guide rails 110. In order to lift the tool 400 and move it to the cutter head near the tunnel boring machine for replacement of the tool 400, the lifting assembly 300 includes a tool transport beam 310 and a lifting member 320. The tool transport beam 310 is arranged behind the cutter head of the tunnel boring machine, and the lifting member 320 is connected to the tool transport beam 310. The tool transporting beam 310 is slidably connected. After the lifting member 320 lifts the tool 400, the lifting member 320 is pulled to make the lifting member 320 slide on the tool transporting beam 310. As a result, the transport component 200 carries the tool 400 and moves on the guide rail 110, so that the tool 400 is transported to the bottom of the lifting component 300. The tool 400 is lifted by the lifting component 300 and moved to the cutter disc near the tunnel boring machine for replacement of the tool 400. This solves the problem that due to limited tool transporting space and lifting points, it is inconvenient to arrange the tool transporting beam throughout the process for tool transport, which consumes a lot of time for tool transportation, reduces tool changing efficiency, and thus affects the construction period.
