Description

Technical Field

[0001] The present disclosure relates to the technical field of installation of a continuous belt conveyor extension section, and in particular to an auxiliary installation system of a continuous belt conveyor extension section. Background Art

[0002] During the construction of the shield equipment, the segments can be assembled while the tunnel is being driven, and continuous tunneling can be achieved except for a short stop for step change. Among them, the continuous belt conveyor used to transport slag out of the shield equipment needs to be continuously extended to adapt to the continuous tunneling of the shield equipment because it is set at the tail of the shield equipment and moves with the shield equipment. At the same time, it is necessary to continuously add roller assemblies to the extension section of the continuous belt conveyor to ensure the normal operation of the continuous belt conveyor by supporting and guiding the roller assemblies.

[0003] At present, the upper and lower belts of the extended section of the continuous belt conveyor are arranged very compactly, which makes the installation of the roller assembly extremely inconvenient and less safe. To ensure safety, the additional installation of the extended section of the conventional continuous belt conveyor requires the continuous belt conveyor to be shut down, which makes it impossible for the shield equipment to achieve continuous excavation. At the same time, due to the long distance of the tunnel, the continuous belt conveyor cannot be stopped or started with load in principle, so the slag on the belt conveyor needs to be cleared before each shutdown. As a result, the excavation construction efficiency of the shield equipment is seriously affected. Summary of the invention

[0029] Embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present disclosure, and are not to be construed as limitations of the present disclosure. On the contrary, the embodiments of the present disclosure include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0030] like Figure 1 and Figure 2 As shown, the embodiment of the present disclosure proposes an auxiliary installation system for an extended section of a continuous belt conveyor 100, comprising: a first trailer 1, at least a second trailer 2 and a third trailer 3, the first trailer 1, the second trailer 2 and the third trailer 3 are sequentially arranged at the tail of the shield equipment, the main section of the continuous belt conveyor 100 is arranged on the first trailer 1, and the extended section of the continuous belt conveyor 100 passes through the second trailer 2 and the third trailer 3 in sequence, the upper belt 101 of the continuous belt conveyor 100 extends upwardly obliquely in the second trailer 2 from the head to the tail of the shield equipment, and the lower belt 102 of the continuous belt conveyor 100 extends horizontally in the second trailer 2 from the head to the tail of the shield equipment, and the third trailer 3 is used to support the installation of the roller assembly 200 of the upper belt 101 and the lower belt 102.

[0031] It can be understood that since the first trailer 1, the second trailer 2 and the third trailer 3 are arranged in sequence at the tail of the shield equipment, and the main section of the continuous belt conveyor 100 is arranged on the first trailer 1, the extension section of the continuous belt conveyor 100 passes through the second trailer 2 and the third trailer 3 in sequence, so that the continuous belt conveyor 100 can use the first trailer 1, the second trailer 2 and the third trailer 3 to achieve the arrangement at the tail of the shield equipment and the follow-up with the shield equipment. At the same time, since the upper belt 101 of the continuous belt conveyor 100 extends upwardly at an angle from the head to the tail of the shield equipment in the second trailer 2, and the lower belt 102 of the continuous belt conveyor 100 extends horizontally in the second trailer 2 from the head to the tail of the shield equipment, the upper belt 101 and the lower belt 102 can form a larger working space at the third trailer 3.

[0032] Therefore, the safe installation of the roller assembly 200 can be achieved by utilizing the working space formed at the third trailer 3. Not only can the support and guidance of the roller assembly 200 be utilized to ensure the normal operation of the continuous belt conveyor 100, but also the supplementary installation of the extension section of the continuous belt conveyor 100 does not require the continuous belt conveyor 100 to be shut down, thereby saving a long downtime and slag cleaning time, thereby realizing continuous excavation of the shield equipment and ensuring a high excavation construction efficiency of the shield equipment.

[0033] It should be noted that the continuous belt conveyor 100 is used to be arranged at the tail of a shield equipment such as a tunnel boring machine (TBM), and its feed end is located below the discharge end of the shield equipment to receive and transport the slag outward. At the same time, in order to adapt to the continuous excavation of the shield equipment, the end of the continuous belt conveyor 100 away from the shield equipment needs to be continuously extended and lengthened, and a roller assembly 200 for supporting and guiding the belt needs to be configured in the extended section of the continuous belt conveyor 100.

[0034] The first trailer 1 is used to arrange the main section of the continuous belt conveyor 100. The specific type of the first trailer 1 can be set according to actual needs and is not limited to this.

[0035] The second trailer 2 is used to arrange the extended section of the continuous belt conveyor 100. The specific type of the second trailer 2 can be set according to actual needs and is not limited to this.

[0036] The number of the second trailers 2 can be set according to actual needs, and there is no limitation on this. For example, the number of the second trailers 2 can be one, two, three, etc. In this embodiment, the number of the second trailers 2 is preferably two.

[0037] The third trailer 3 is used for arranging the extension section of the continuous belt conveyor 100 and for auxiliary installation of the roller assembly 200. The specific type of the third trailer 3 can be set according to actual needs and is not limited thereto.

[0038] Among them, the first trailer 1, the second trailer 2 and the third trailer 3 are moved along under the towing of the shield equipment, and the upper belt 101 and the lower belt 102 leave a large working space at the third trailer 3, so that the roller assembly 200 can be safely installed while the shield equipment is continuously excavating.

[0039] The inclination angle of the upper belt 101, or the angle between the upper belt 101 and the lower belt 102, can be set according to actual needs without limitation. For example, the inclination angle of the upper belt 101 can be 3 degrees, 4 degrees, 5 degrees, etc.

[0040] like Figure 2 and Figure 4 As shown, in some embodiments, the third trailer 3 includes: a third vehicle body 31 and a work platform, the third vehicle body 31 is arranged at one end of the second trailer 2 away from the first trailer 1, and the work platform is arranged on the third vehicle body 31, and the work platform is used for installing the cross beam 204, the longitudinal beam 205, the upper roller 207 and the lower roller 209 in the roller assembly 200. Among them, the cross beam 204 is arranged on the segment of the tunnel, and the longitudinal beam 205 is arranged on the cross beam 204, the upper roller 207 is rotatably arranged on the top of the longitudinal beam 205, and the upper belt 101 is arranged on the upper roller 207, the lower roller 209 is rotatably arranged on the bottom of the longitudinal beam 205, and the lower belt 102 is arranged on the lower roller 209.

[0041] It can be understood that since the third car body 31 is arranged at the end of the second trailer 2 away from the first trailer 1, and the working platform is arranged on the third car body 31, the third car body 31 can be dragged by the second trailer 2 to achieve follow-up movement with the shield equipment, and the upper belt 101 and the lower belt 102 form a larger working space at the working platform, so that the working platform can be used to install the cross beam 204, the longitudinal beam 205, the upper roller 207 and the lower roller 209 in the roller assembly 200 while the shield equipment is continuously excavating, and then the upper roller 207 and the lower roller 209 are used to support and guide the upper belt 101 and the lower belt 102, thereby ensuring the normal operation of the continuous belt conveyor 100.

[0042] It should be noted that the third vehicle body 31 is used to carry the working platform and is connected to the second trailer 2 to achieve follow-up. The specific type of the third vehicle body 31 can be set according to actual needs and is not limited to this. For example, the third vehicle body 31 may include: a plurality of connected transverse structural beams, a plurality of longitudinal structural beams and a plurality of vertical structural beams. The bottom of the third vehicle body 31 is provided with running wheels, and the running wheels are rollingly set on the track at the bottom of the tunnel.

[0043] The working platform is used for installing the roller assembly 200 , and the specific type of the working platform can be set according to actual needs, and there is no limitation on this.

[0044] For the roller assembly 200, the cross beam 204 is set along the width direction of the tunnel and arranged on the tunnel segment, playing the role of supporting the longitudinal beam 205. The longitudinal beam 205 is set along the length direction (excavation direction) of the tunnel and arranged on the cross beam 204, playing the role of supporting the upper roller 207 and the lower roller 209. Two longitudinal beams 205 are usually set.

[0045] The upper roller 207 is used to support and guide the upper belt 101 , and the lower roller 209 is used to support and guide the lower belt 102 .

[0046] like Figure 2 and Figure 4 As shown, in some embodiments, the working platform includes: a first platform 32, a second platform 33 and a third platform 34, and the first platform 32, the second platform 33 and the third platform 34 are sequentially arranged on the third vehicle body 31 along the direction from the head to the tail of the shield equipment, and the height of the first platform 32, the height of the second platform 33 and the height of the third platform 34 decrease sequentially along the direction from the head to the tail of the shield equipment.

[0047] The first platform 32 is used for installing the first corner piece 201 and the chain 202 in the roller assembly 200 , wherein the first corner piece 201 is arranged on the pipe segment, and the chain 202 is arranged on the first corner piece 201 .

[0048] The second platform 33 is used for installing the second corner piece 203, the cross beam 204, the longitudinal beam 205, the upper roller frame 206 and the upper roller 207 in the roller assembly 200, wherein the second corner piece 203 is arranged on the pipe segment, and the cross beam 204 is arranged between the second corner piece 203 and the chain 202, the upper roller frame 206 is arranged on the top of the longitudinal beam 205, and the upper roller 207 is rotatably arranged on the upper roller frame 206.

[0049] The third platform 34 is used for installing the lower roller frame 208 and the lower roller 209 in the roller assembly 200 . The lower roller frame 208 is arranged at the bottom of the longitudinal beam 205 , and the lower roller 209 is rotatably arranged on the lower roller frame 208 .

[0050] It can be understood that since the first platform 32, the second platform 33 and the third platform 34 are arranged in sequence on the third vehicle body 31 along the direction from the head to the tail of the shield equipment, and the height of the first platform 32, the height of the second platform 33 and the height of the third platform 34 decrease in sequence along the direction from the head to the tail of the shield equipment, when the shield equipment drives the first trailer 1, the second trailer 2 and the third trailer 3 to move, the first platform 32, the second platform 33 and the third platform 34 in the third trailer 3 can be moved to the installation position of the roller assembly 200 in sequence.

[0051] Furthermore, when the first platform 32 moves to the installation position, the first platform 32 can utilize its own height adaptation to achieve auxiliary installation of the first corner fitting 201 and the chain 202, thereby utilizing the first corner fitting 201 and the chain 202 arranged on the pipe segment to perform subsequent installation of the cross beam 204.

[0052] When the second platform 33 moves to the installation position, the second platform 33 can use its own height adaptation to achieve the auxiliary installation of the second corner piece 203, the crossbeam 204, the longitudinal beam 205, the upper roller frame 206 and the upper roller 207, so as to use the upper roller 207 arranged on the upper roller frame 206 to support and guide the upper belt 101, and use the longitudinal beam 205 arranged on the crossbeam 204 to carry out the subsequent installation of the lower roller 209.

[0053] When the third platform 34 moves to the installation position, the third platform 34 can use its own height adaptation to achieve auxiliary installation of the lower roller frame 208 and the lower roller 209, thereby using the lower roller 209 arranged on the lower roller frame 208 to support and guide the lower belt 102.

[0054] Therefore, by utilizing the relative position arrangement of the first platform 32, the second platform 33 and the third platform 34 and the follow-up movement of the third trailer 3 and the shield equipment, the first corner piece 201, the chain 202, the second corner piece 203, the cross beam 204, the longitudinal beam 205, the upper roller frame 206, the upper roller 207, the lower roller frame 208 and the lower roller 209 are installed in sequence, thereby meeting the needs of supplementary installation of the extended section of the continuous belt conveyor 100 while ensuring a high excavation construction efficiency of the shield equipment.

[0055] It should be noted that the first platform 32 is used to assist in the installation of the first corner piece 201 and the chain 202. Since the first corner piece 201 and the chain 202 need to be arranged at the top of the tunnel, the height of the first platform 32 is set relatively high. At the same time, the first corner piece 201 and the chain 202 are used to install the cross beam 204, which needs to be installed before the cross beam 204. Therefore, the first platform 32 is located at one end of the second platform 33 close to the shield equipment. The specific type of the first platform 32 can be set according to actual needs, and there is no limitation to this. For example, the first platform 32 is a plate structure. Among them, since the first platform 32 only needs to install the first corner piece 201 and the chain 202, it takes less time, so the length of the first platform 32 along the direction from the head to the tail of the shield equipment can be set smaller.

[0056] The second platform 33 is used to assist in the installation of the second corner piece 203, the cross beam 204, the longitudinal beam 205, the upper roller frame 206 and the upper roller 207. Since the second corner piece 203, the cross beam 204, the longitudinal beam 205, the upper roller frame 206 and the upper roller 207 need to be arranged in the middle of the tunnel, the height of the second platform 33 is set to be medium. At the same time, the cross beam 204 is installed after the first corner piece 201 and the chain 202, and the upper roller 207 is installed before the lower roller 209. Therefore, the second platform 33 is located between the first platform 32 and the third platform 34. The specific type of the second platform 33 can be set according to actual needs and is not limited to this. For example, the second platform 33 is a plate structure. Among them, since the second platform 33 needs to install the second corner piece 203, the cross beam 204, the longitudinal beam 205, the upper roller frame 206 and the upper roller 207, which takes a long time, the length of the second platform 33 along the direction from the head to the tail of the shield equipment can be set larger.

[0057] The third platform 34 is used to assist in the installation of the lower roller frame 208 and the lower roller 209. Since the lower roller frame 208 and the lower roller 209 need to be arranged at the bottom of the tunnel, the height of the third platform 34 is set relatively low. At the same time, the lower roller 209 is installed after the upper roller 207. Therefore, the third platform 34 is located at the end of the second platform 33 away from the shield equipment. The specific type of the third platform 34 can be set according to actual needs, and there is no limitation to this. For example, the third platform 34 is a plate structure. Among them, since the third platform 34 only needs to install the lower roller frame 208 and the lower roller 209, it takes less time, so the length of the third platform 34 along the direction from the head to the tail of the shield equipment can be set smaller.

[0058] During the excavation process, the shield equipment moves at an extremely slow speed, for example, 60 mm per minute. Therefore, while leaving an extremely safe working space for the upper belt 101 and the lower belt 102, the first platform 32, the second platform 33 and the third platform 34 can be used to achieve non-stop installation of the roller assembly 200.

[0059] The first corner piece 201, chain 202, second corner piece 203, cross beam 204, longitudinal beam 205, upper roller frame 206, upper roller 207, lower roller frame 208 and lower roller 209 in the roller assembly 200 can be manually installed by operators on the first platform 32, the second platform 33 and the third platform 34 with the help of tools, or can be automatically installed by robotic arms on the first platform 32, the second platform 33 and the third platform 34, and there is no limitation to this.

[0060] like Figure 2 As shown, in some embodiments, the third trailer 3 also includes: a third support roller 35 and at least one redirecting roller 36, the third support roller 35 is rotatably set on the second platform 33, and multiple third support rollers 35 are horizontally distributed along the direction from the head to the tail of the shield equipment, the lower belt 102 is set on multiple third support rollers 35, the redirecting roller 36 is rotatably set at one end of the second platform 33 close to the third platform 34, and the lower belt 102 bypasses the redirecting roller 36 and is located above the lower roller 209.

[0061] It can be understood that since the third support roller 35 is rotatably set on the second platform 33, and multiple third support rollers 35 are horizontally distributed along the direction from the head to the tail of the shield equipment, the lower belt 102 is set on multiple third support rollers 35, so that when the lower belt 102 passes through the third trailer 3, it can use the third support rollers 35 on the second platform 33 to achieve support and guidance, thereby ensuring the stable movement of the lower belt 102 and ensuring a larger working space between the lower belt 102 and the upper belt 101.

[0062] Since the redirecting roller 36 is rotatably arranged at one end of the second platform 33 close to the third platform 34, and the lower belt 102 bypasses the redirecting roller 36 and is located above the lower roller 209, the lower belt 102 leaves a larger working space at the second platform 33 while being able to utilize the redirection of the redirecting roller 36 to deviate upward at the third platform 34. Therefore, after the lower roller 209 in the roller assembly 200 is installed, the lower belt 102 can be stably arranged on the installed lower roller 209 under the dragging and following of the shield equipment, thereby ensuring the normal operation of the continuous belt conveyor 100.

[0063] It should be noted that the third support roller 35 is used to support and guide the lower belt 102 passing through the third trailer 3. The specific type of the third support roller 35 can be set according to actual needs and is not limited to this. For example, the third support roller 35 is a roller structure.

[0064] The redirecting roller 36 is used to redirect the lower belt 102 so that the lower belt 102 in a lower position can be adjusted upward so that it can fall onto the lower roller 209 after the lower roller 209 is installed. The specific type of the redirecting roller 36 can be set according to actual needs and is not limited to this. For example, the redirecting roller 36 is a roller structure. The number of redirecting rollers 36 can be two, and the two redirecting rollers 36 are distributed in high and low positions. The lower belt 102 successively bypasses the redirecting roller 36 located at a low position and the redirecting roller 36 located at a high position to achieve upward position adjustment.

[0065] In some embodiments, the third trailer 3 further includes: at least one fence, which is arranged around the first platform 32 , and / or the fence is arranged around the second platform 33 , and / or the fence is arranged around the third platform 34 .

[0066] It can be understood that, since the fence is arranged around the first platform 32, the first platform 32 can be protected by the fence; since the fence is arranged around the second platform 33, the second platform 33 can be protected by the fence; since the fence is arranged around the third platform 34, the third platform 34 can be protected by the fence. Therefore, the setting of the fence makes the operation of the third trailer 3 safer.

[0067] It should be noted that the fence is used for enclosure protection to reduce the falling of workers, equipment, etc. from the third trailer 3. The specific type of the fence can be set according to actual needs and is not limited to this.
