Description

Technical Field

[0001] The present disclosure relates to the technical field of installation of an extension section of a continuous belt conveyor, and in particular to a method for installing an extension section of a continuous belt conveyor without stopping the machine. 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

[0004] The present disclosure aims to solve one of the technical problems in the related art at least to some extent.

[0005] To this end, an object of the present disclosure is to provide a method for installing an extension section of a continuous belt conveyor without stopping the machine.

[0006] To achieve the above-mentioned purpose, the present disclosure provides a method for non-stop installation of an extension section of a continuous belt conveyor, comprising: sequentially arranging a first trailer, at least one second trailer and a third trailer at the tail of a shield machine; arranging the main section of the continuous belt conveyor on the first trailer; sequentially passing the extension section of the continuous belt conveyor through the second trailer and the third trailer, and extending the upper belt of the continuous belt conveyor upwardly in an inclined direction from the head to the tail of the shield machine in the second trailer, and extending the lower belt of the continuous belt conveyor horizontally in the direction from the head to the tail of the shield machine in the second trailer; when the shield machine moves forward and drives the third trailer to move to an installation position, sequentially installing the upper roller and the lower roller of the roller assembly on the tunnel segment in the third trailer, and setting the upper belt on the upper roller, and setting the lower belt on the lower roller.

[0007] Optionally, the non-stop installation method also includes: arranging a first platform, a second platform and a third platform in sequence in the third trailer along the direction from the head to the tail of the shield equipment, and making the heights of the first platform, the second platform and the third platform decrease in sequence along the direction from the head to the tail of the shield equipment; when the shield equipment moves forward and drives the first platform to move to the installation position, installing the chain of the roller assembly on the pipe segment on the first platform; when the shield equipment moves forward and drives the second platform to move to the installation position, installing the cross beam, the longitudinal beam and the upper roller of the roller assembly on the pipe segment in sequence on the second platform; when the shield equipment moves forward and drives the third platform to move to the installation position, installing the lower roller of the roller assembly on the pipe segment on the third platform.

[0008] Optionally, the non-stop installation method also includes: when the shield equipment moves forward and drives the first platform to move to the installation position, setting the first corner piece of the roller assembly on the pipe segment on the first platform; and setting the chain on the first corner piece.

[0009] Optionally, the non-stop installation method also includes: when the shield equipment moves forward and drives the second platform to move to the installation position, setting the second corner piece of the roller assembly on the pipe segment on the second platform; setting the crossbeam between the second corner piece and the chain; setting the longitudinal beam on the crossbeam; setting the upper roller frame of the roller assembly on the top of the longitudinal beam; and rotatably setting the upper roller on the upper roller frame.

[0010] Optionally, the non-stop installation method also includes: when the shield equipment moves forward and drives the third platform to move to the installation position, setting the lower roller frame of the roller assembly on the third platform at the bottom of the longitudinal beam; and rotatably setting the lower roller on the lower roller frame.

[0011] Optionally, the non-stop installation method also includes: when the shield equipment moves forward and drives the third platform to move to the installation position, the inclined beam of the roller assembly is set on the third platform between the lower roller frame and the pipe segment.

[0012] Optionally, the non-stop installation method also includes: horizontally extending the lower belt along the direction from the head to the tail of the shield equipment on the second platform; and redirecting the lower belt upward at the end of the second platform close to the third platform so that the lower belt is located above the lower roller.

[0013] Optionally, the non-stop installation method further includes: extending the upper belt in the third trailer downwardly along the direction from the head to the tail of the shield equipment.

[0014] Optionally, the non-stop installation method further includes: offsetting one end of the lower belt close to the shield equipment downward by a preset distance.

[0015] The technical solution provided by the present disclosure may have the following beneficial effects:

[0016] The first trailer, at least one second trailer and the third trailer are sequentially arranged at the tail of the shield equipment, and the main section of the continuous belt conveyor is arranged on the first trailer, and the extension section of the continuous belt conveyor is sequentially passed through the second trailer and the third trailer, so that the continuous belt conveyor can be arranged at the tail of the shield equipment and follow the shield equipment using the first trailer, the second trailer and the third trailer. At the same time, the upper belt of the continuous belt conveyor is tilted and extended upward in the second trailer from the head to the tail of the shield equipment, and the lower belt of the continuous belt conveyor is horizontally extended in the second trailer from the head to the tail of the shield equipment, so that the upper belt and the lower belt can form a larger working space at the third trailer. Therefore, when the shield equipment moves forward and drives the third trailer to move to the installation position, the upper roller and the lower roller of the roller assembly can be safely installed on the tunnel segment in sequence in the third trailer by utilizing the working space formed at the third trailer. Not only can the support and guidance of the roller assembly ensure the normal operation of the continuous belt conveyor, but also the supplementary installation of the extension section of the continuous belt conveyor does not require the continuous belt conveyor to be shut down, thereby saving a long downtime and slag cleaning time, thereby realizing continuous excavation of the shield equipment and ensuring high excavation construction efficiency of the shield equipment.

[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 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the embodiment of the present disclosure provides a method for installing an extension section of a continuous belt conveyor 100 without stopping the machine, comprising:

[0031] S1: placing a first trailer 1, at least one second trailer 2 and a third trailer 3 at the tail of the shield equipment in sequence;

[0032] S2: placing the main section of the continuous belt conveyor 100 on the first trailer 1;

[0033] S3: The extended section of the continuous belt conveyor 100 is passed through the second trailer 2 and the third trailer 3 in sequence, and the upper belt 101 of the continuous belt conveyor 100 is extended upwardly in the second trailer 2 along the direction from the head to the tail of the shield equipment, and the lower belt 102 of the continuous belt conveyor 100 is extended horizontally in the second trailer 2 along the direction from the head to the tail of the shield equipment;

[0034] S4: When the shield equipment moves forward and drives the third trailer 3 to move to the installation position, the upper roller 207 and the lower roller 209 of the roller assembly 200 are installed on the tunnel segment in sequence in the third trailer 3, and the upper belt 101 is set on the upper roller 207, and the lower belt 102 is set on the lower roller 209.

[0035] It can be understood that the first trailer 1, at least one second trailer 2 and the third trailer 3 are sequentially arranged at the tail of the shield equipment, and the main section of the continuous belt conveyor 100 is arranged on the first trailer 1, and 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, the upper belt 101 of the continuous belt conveyor 100 is extended upwardly in the second trailer 2 along the direction from the head to the tail of the shield equipment, and the lower belt 102 of the continuous belt conveyor 100 is extended horizontally in the second trailer 2 along the direction from the head to the tail of the shield equipment, so that the upper belt 101 and the lower belt 102 can form a larger working space at the third trailer 3.

[0036] Therefore, when the shield equipment moves forward and drives the third trailer 3 to move to the installation position, the upper roller 207 and the lower roller 209 of the roller assembly 200 can be safely installed on the tunnel segment in sequence in the third trailer 3 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 extended section of the continuous belt conveyor 100 does not require the shutdown of the continuous belt conveyor 100, thereby saving a long shutdown time and slag cleaning time, thereby realizing continuous excavation of the shield equipment and ensuring a high excavation construction efficiency of the shield equipment.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] like Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments, the non-stop installation method further includes:

[0045] In the third trailer 3, a first platform 32, a second platform 33 and a third platform 34 are sequentially arranged along the direction from the head to the tail of the shield equipment, and the heights of the first platform 32, the second platform 33 and the third platform 34 are sequentially reduced along the direction from the head to the tail of the shield equipment;

[0046] When the shield equipment moves forward and drives the first platform 32 to move to the installation position, the chain 202 of the roller assembly 200 is installed on the segment on the first platform 32;

[0047] When the shield equipment moves forward and drives the second platform 33 to move to the installation position, the cross beam 204, the longitudinal beam 205 and the upper roller 207 of the roller assembly 200 are sequentially installed on the segment on the second platform 33;

[0048] When the shield equipment moves forward and drives the third platform 34 to move to the installation position, the lower roller 209 of the roller assembly 200 is installed on the pipe segment on the third platform 34.

[0049] It can be understood that the first platform 32, the second platform 33 and the third platform 34 are sequentially arranged in the direction from the head to the tail of the shield equipment in the third trailer 3, and the heights of the first platform 32, the second platform 33 and the third platform 34 are sequentially reduced in the direction from the head to the tail of the shield equipment, so that 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.

[0050] Furthermore, when the first platform 32 moves to the installation position, the first platform 32 can utilize its own height adaptation to realize the auxiliary installation of the chain 202 , thereby utilizing the chain 202 arranged on the pipe segment to perform subsequent installation of the crossbeam 204 .

[0051] When the second platform 33 moves to the installation position, the second platform 33 can use its own height adaptation to achieve auxiliary installation of the crossbeam 204, the longitudinal beam 205 and the upper roller 207, thereby using the upper roller 207 arranged on the top of the longitudinal beam 205 to support and guide the upper belt 101, and using the longitudinal beam 205 arranged on the crossbeam 204 to install the subsequent lower roller 209.

[0052] When the third platform 34 moves to the installation position, the third platform 34 can utilize its own height adaptation to achieve auxiliary installation of the lower roller 209 , thereby utilizing the lower roller 209 arranged at the bottom of the longitudinal beam 205 to support and guide the lower belt 102 .

[0053] 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 chain 202, the cross beam 204, the longitudinal beam 205, the upper roller 207 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.

[0054] It should be noted that the shield equipment moves at an extremely slow speed during the excavation process, 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.

[0055] like Figure 3 and Figure 5 As shown, in some embodiments, the non-stop installation method further includes:

[0056] When the shield equipment moves forward and drives the first platform 32 to move to the installation position, the first corner piece 201 of the roller assembly 200 is set on the pipe segment on the first platform 32;

[0057] The chain 202 is disposed on the first corner piece 201 .

[0058] It is understandable that when the first platform 32 moves to the installation position, the first platform 32 can use its own height adaptation to achieve auxiliary installation of the first corner piece 201 and the chain 202, so as to use the chain 202 arranged on the pipe segment to install the subsequent beam 204.

[0059] 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, and the first platform 32 is set on the third body 31 of the third trailer 3. 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.

[0060] like Figure 3 and Figure 5 As shown, in some embodiments, the non-stop installation method further includes:

[0061] When the shield equipment moves forward and drives the second platform 33 to move to the installation position, the second corner piece 203 of the roller assembly 200 is set on the pipe segment on the second platform 33;

[0062] The crossbeam 204 is disposed between the second angle piece 203 and the chain 202;

[0063] The longitudinal beam 205 is arranged on the cross beam 204;

[0064] The upper roller frame 206 of the roller assembly 200 is arranged on the top of the longitudinal beam 205;

[0065] The upper roller 207 is rotatably arranged on the upper roller frame 206 .

[0066] It can be understood that 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.

[0067] It should be noted that 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, and the second platform 33 is arranged on the third body 31 of the third trailer 3. 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.

[0068] like Figure 3 and Figure 5 As shown, in some embodiments, the non-stop installation method further includes:

[0069] When the shield equipment moves forward and drives the third platform 34 to move to the installation position, the lower roller frame 208 of the roller assembly 200 is set at the bottom of the longitudinal beam 205 on the third platform 34;

[0070] The lower roller 209 is rotatably arranged on the lower roller frame 208 .

[0071] It can be understood that 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.

[0072] It should be noted that 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, and the third platform 34 is set on the third body 31 of the third trailer 3. 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.

[0073] 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.

[0074] In some embodiments, the non-stop installation method further includes:

[0075] When the shield equipment moves forward and drives the third platform 34 to move to the installation position, the inclined beam of the roller assembly 200 is set between the lower roller frame 208 and the pipe segment on the third platform 34.

[0076] It can be understood that 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 inclined beam, thereby using the inclined beam arranged on the lower roller frame 208 to achieve structural reinforcement, thereby ensuring the stable operation of the upper belt 101 and the lower belt 102.

[0077] like Figure 3 As shown, in some embodiments, the non-stop installation method further includes:

[0078] On the second platform 33, the lower belt 102 is horizontally extended from the head to the tail of the shield equipment;

[0079] The lower belt 102 is redirected upward at one end of the second platform 33 close to the third platform 34 so that the lower belt 102 is located above the lower roller 209 .

[0080] It can be understood that the lower belt 102 is horizontally extended from the head to the tail of the shield equipment on the second platform 33, and the lower belt 102 is redirected upward at the end of the second platform 33 close to the third platform 34, so that the lower belt 102 can leave a larger working space at the second platform 33 while being able to shift upward at the third platform 34 by means of redirection. 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.

[0081] like Figure 3 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] like Figure 3 As shown, in some embodiments, the non-stop installation method further includes: extending the upper belt 101 in the third trailer 3 downwardly in a direction from the head to the tail of the shield equipment.

[0087] It can be understood that the upper belt 101 is extended downwardly in the third trailer 3 along the direction from the head to the tail of the shield equipment, so that the upper belt 101 leaves a larger working space at the end of the third trailer 3 close to the shield equipment, and can be arranged downwardly by tilting at the end of the third trailer 3 away from the shield equipment.
