Technical Field

[0001] The present invention relates to the technical field of continuous belt conveyor extension section installation, and in particular to a continuous belt conveyor extension section structure and a construction method adapted for a lining trolley. Background Art

[0002] A continuous belt conveyor is a continuous material transport equipment used for tunnel excavation and slag removal. Since the continuous belt conveyor moves with the shield equipment, the belt needs to be continuously extended to adapt to the continuous excavation of the shield equipment. At the same time, a roller group needs to be arranged in the extended section of the continuous belt conveyor to utilize the support and guidance of the roller group to ensure the normal operation of the continuous belt conveyor.

[0003] At present, when the lining trolley is carrying out lining operation, the roller group located at the front end of the lining trolley and arranged on the inner wall of the tunnel needs to be removed. At the same time, the roller group needs to be installed on the inner wall of the tunnel lining layer at the rear end of the lining trolley. This process is not only inconvenient to operate, but also requires the lining trolley to be shut down, resulting in low tunnel construction efficiency and a long construction period.

[0031] 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.

[0032] like Figure 1 As shown, the embodiment of the present disclosure proposes a continuous belt conveyor extension section structure adapted to a lining trolley 100, comprising: a longitudinal beam 1, a plurality of roller groups 2, at least one first supporting device 3, at least one second supporting device 4, and at least one third supporting device 5. The longitudinal beam 1 is arranged along the length direction of the tunnel 200, and a plurality of roller groups 2 are arranged at intervals on the longitudinal beam 1 and are used to arrange the belt. The first supporting device 3 is located at the front end of the lining trolley 100 and is detachably arranged on the inner wall of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the first supporting device 3, the second supporting device 4 is arranged on the lining trolley 100, and the longitudinal beam 1 is slidably arranged on the second supporting device 4, the third supporting device 5 is located at the rear end of the lining trolley 100 and is detachably arranged on the inner wall of the lining layer 300 of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the third supporting device 5.

[0033] It can be understood that since the multiple roller groups 2 are arranged at intervals on the longitudinal beam 1, and the part of the longitudinal beam 1 located at the front end of the lining trolley 100 is detachably arranged on the first supporting device 3, the part of the longitudinal beam 1 located at the lining trolley 100 is slidably arranged on the second supporting device 4, and the part of the longitudinal beam 1 located at the rear end of the lining trolley 100 is detachably arranged on the third supporting device 5, the longitudinal beam 1 can be arranged in the tunnel 200 by utilizing the support of the first supporting device 3, the second supporting device 4 and the third supporting device 5, so as to effectively support the multiple roller groups 2, and then utilize the support and guidance of the multiple roller groups 2 to ensure the normal operation of the continuous belt conveyor.

[0034] At the same time, by utilizing the support cooperation of the second supporting device 4, the longitudinal beam 1 can directly penetrate the lining trolley 100 from the front end of the lining trolley 100 and extend to the rear end of the lining trolley 100, which not only enables the extended section of the continuous belt conveyor to achieve consistency in its center distance and installation height, but also avoids the influence between the disassembly and assembly operations of the roller group 2 and the lining operations of the lining trolley 100. Therefore, while achieving stable operation of the continuous belt conveyor, the lining trolley 100 can also perform lining operations simultaneously, thereby effectively improving the construction efficiency of the tunnel 200 and greatly shortening the construction period.

[0035] It should be noted that the longitudinal beam 1 is used to carry the roller group 2, so as to support and guide the belt by the roller group 2, and the longitudinal beam 1 can pass through the lining trolley 100 by the support and guidance of the second support device 4, and does not affect the movement of the lining trolley 100, so that the construction work of the continuous belt conveyor extension section and the lining work of the lining trolley 100 can be carried out synchronously. The specific type of the longitudinal beam 1 can be set according to actual needs, and there is no limitation to this. For example, the longitudinal beam 1 is a beam structure arranged along the length direction of the tunnel 200, and the longitudinal beam 1 can be set to two, and the two longitudinal beams 1 are spaced apart along the width direction of the tunnel 200. The roller frame of the roller group 2 is set on the two longitudinal beams 1 by bolts and other fixings, and the two longitudinal beams 1 can be respectively set on the first support device 3 and the third support device 5 by bolts and other fixings.

[0036] The roller group 2 is used to support and guide the belt, which is arranged on the longitudinal beam 1. Due to the cooperation of the first supporting device 3, the second supporting device 4 and the third supporting device 5, during the lining operation of the lining trolley 100, it is only necessary to remove the first supporting device 3 at the front end and install the third supporting device 5 at the rear end. Compared with the removal and installation of all roller components in the related embodiments, the disassembly and assembly operation of the extension section structure of this embodiment is simpler and the construction efficiency is higher. The specific type of the roller group 2 can be set according to actual needs and is not limited to this. For example, the roller group 2 can include roller frames, rollers and other components.

[0037] The first supporting device 3 is used to be arranged in the unlined section of the tunnel 200 to support the longitudinal beam 1. The specific type of the first supporting device 3 can be set according to actual needs and is not limited to this. The number of the first supporting devices 3 can be one, two, three, four, five, etc., and is not limited to this.

[0038] The second supporting device 4 is used to be arranged on the lining trolley 100 to support the longitudinal beam 1. At the same time, the sliding connection between the second supporting device 4 and the longitudinal beam 1 enables the lining trolley 100 and the longitudinal beam 1 to move relative to each other, thereby ensuring that the lining of the lining trolley 100 and the installation of the extension section of the continuous belt conveyor can be synchronized. The specific type of the second supporting device 4 can be set according to actual needs and is not limited to this. Among them, the number of the second supporting devices 4 can be one, two, three, four, five, etc., and is not limited to this.

[0039] The third supporting device 5 is used to be arranged in the lining section of the tunnel 200 to support the longitudinal beam 1. The specific type of the third supporting device 5 can be set according to actual needs and is not limited to this. The number of the third supporting devices 5 can be one, two, three, four, five, etc., and is not limited to this.

[0040] Among them, the lining trolley 100 is located between the unlined section and the lined section of the tunnel 200. With the lining operation of the lining trolley 100, the unlined section is gradually converted into the lined section, that is, the exposed inner wall of the tunnel 200 gradually forms a lining layer 300 by the lining operation of the lining trolley 100. At the same time, in conjunction with the removal of the first supporting device 3 and the installation of the third supporting device 5, the transition of the longitudinal beam 1 from the unlined section to the lined section can be achieved.

[0041] like Figure 2 As shown, in some embodiments, the second supporting device 4 includes: a first support 41 and at least one first guide roller 42, the first support 41 is arranged on the lining trolley 100, the first guide roller 42 is arranged along the width direction of the tunnel 200 and is rotatably arranged on the first support 41, and the longitudinal beam 1 is movably arranged on the first guide roller 42.

[0042] It can be understood that since the first support 41 is arranged on the lining trolley 100, the first guide roller 42 is arranged along the width direction of the tunnel 200 and rotatably arranged on the first support 41, and the longitudinal beam 1 is movably arranged on the first guide roller 42, the longitudinal beam 1 can utilize the support and guidance of the first guide roller 42 to achieve a sliding arrangement on the lining trolley 100, thereby avoiding interference between the longitudinal beam 1 and the lining trolley 100, and ensuring that the lining operation of the lining trolley 100 and the installation operation of the continuous belt conveyor extension section can be carried out synchronously.

[0043] It should be noted that the first support 41 is used to carry the first guide roller 42 so as to utilize the first guide roller 42 to support and guide the longitudinal beam 1. The specific type of the first support 41 can be set according to actual needs and is not limited to this. For example, the first support 41 can be an I-beam, and the first support 41 is arranged on the portal of the lining trolley 100 along the width direction of the tunnel 200.

[0044] The first guide roller 42 is used to support and guide the longitudinal beam 1. The specific type of the first guide roller 42 can be set according to actual needs, and there is no limitation on this. For example, the first guide roller 42 is a roller structure, and the first guide roller 42 is rotatably arranged on two opposite plates of the first support 41 by means of a bearing. When there are two longitudinal beams 1, there can also be two first guide rollers 42, and the two first guide rollers 42 support and guide the two longitudinal beams 1 respectively.

[0045] like Figure 2 As shown, in some embodiments, the second supporting device 4 also includes: a second support 43 and at least one second guide roller 44, the second support 43 is arranged on the lining trolley 100, and the second support 43 and the first support 41 are spaced apart along the length direction of the tunnel 200, the second guide roller 44 is arranged along the height direction of the tunnel 200 and is rotatably arranged on the second support 43, and the second guide roller 44 is located on the outside of the longitudinal beam 1.

[0046] It can be understood that since the second support 43 is arranged on the lining trolley 100, the second guide roller 44 is arranged along the height direction of the tunnel 200 and is rotatably arranged on the second support 43, and the second guide roller 44 is located on the outside of the longitudinal beam 1, the longitudinal beam 1 can utilize the guidance of the second guide roller 44 to achieve lateral limitation on the lining trolley 100, thereby avoiding the deviation or even falling off of the longitudinal beam 1 on the lining trolley 100, thereby ensuring stable lining operations and extension section installation operations.

[0047] It should be noted that the second support 43 is used to carry the second guide roller 44 so as to utilize the second guide roller 44 to achieve lateral limitation of the longitudinal beam 1. The specific type of the second support 43 can be set according to actual needs and is not limited to this. For example, the second support 43 can be a seat structure.

[0048] The second guide roller 44 is used to guide and limit the longitudinal beam 1. The specific type of the second guide roller 44 can be set according to actual needs, and there is no limitation on this. For example, the second guide roller 44 is a roller structure, and the first guide roller 42 is rotatably arranged on the second support 43 using a bearing. Among them, two second guide rollers 44 can be provided, and the two second guide rollers 44 are respectively located on the outsides of the two longitudinal beams 1.

[0049] In some embodiments, an outer surface of the second guide roller 44 is covered with an elastic pad.

[0050] It can be understood that since the outer surface of the second guide roller 44 is sleeved with an elastic pad, the second guide roller 44 can not only achieve lateral limiting of the longitudinal beam 1, but also utilize the elastic pad to adapt to the protruding structure of the longitudinal beam 1, thereby reducing the wear between the longitudinal beam 1 and the second guide roller 44, while ensuring smooth relative movement between the longitudinal beam 1 and the lining trolley 100.

[0051] It should be noted that the elastic pad is used for protection between the longitudinal beam 1 and the second guide roller 44. The specific type of the elastic pad can be set according to actual needs and is not limited to this.

[0052] In some embodiments, the outer surface of the first guide roller 42 is provided with a plurality of annular protrusions distributed at intervals along the width direction of the tunnel 200 , and annular grooves are formed between adjacent annular protrusions.

[0053] It can be understood that since the outer surface of the first guide roller 42 is provided with a plurality of annular protrusions distributed at intervals along the width direction of the tunnel 200, and annular grooves are formed between adjacent annular protrusions, the outer surface of the first guide roller 42 forms a concave-convex orderly guiding structure, thereby utilizing the concave-convex guiding structure to ensure stable movement of the longitudinal beam 1 on the lining trolley 100.

[0054] It should be noted that the annular protrusion and the annular groove are used to guide the longitudinal beam 1 along the length direction of the tunnel 200 during the rotation of the first guide roller 42. The specific types of the annular protrusion and the annular groove can be set according to actual needs and are not limited to this.

[0055] like Figure 3 As shown, in some embodiments, the first supporting device 3 includes: a first cross beam 31 and a first diagonal brace 32, the first cross beam 31 is detachably arranged on the inner wall of the tunnel 200 along the width direction of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the first cross beam 31, the first diagonal brace 32 is detachably arranged obliquely on the inner wall of the tunnel 200, and one end of the first diagonal brace 32 away from the inner wall of the tunnel 200 is connected to the end of the first cross beam 31 away from the inner wall of the tunnel 200.

[0056] It can be understood that since the first crossbeam 31 is detachably arranged on the inner wall of the tunnel 200 along the width direction of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the first crossbeam 31, the part of the longitudinal beam 1 located at the front end of the lining trolley 100 can be stably arranged on the inner wall of the tunnel 200 by using the first crossbeam 31, and at the same time, it is convenient to utilize the detachable structure of the first crossbeam 31 to realize the transition installation of the continuous belt conveyor extension section from the unlined section of the tunnel 200 to the lined section.

[0057] Since the first diagonal brace 32 is detachably arranged at an angle on the inner wall of the tunnel 200, and the end of the first diagonal brace 32 away from the inner wall of the tunnel 200 is connected to the end of the first crossbeam 31 away from the inner wall of the tunnel 200, the first diagonal brace 32 can achieve structural reinforcement of the first crossbeam 31, so that the first crossbeam 31 can more stably support the longitudinal beam 1. At the same time, the detachable structure of the first diagonal brace 32 is utilized to facilitate the transition installation of the continuous belt conveyor extension section from the unlined section to the lined section of the tunnel 200.

[0058] It should be noted that the first cross beam 31 is used to support the portion of the longitudinal beam 1 located at the front end of the lining trolley 100. The specific type of the first cross beam 31 can be set according to actual needs and is not limited to this. For example, the first cross beam 31 can be a beam structure arranged along the width direction of the tunnel 200.

[0059] The first diagonal brace 32 is used to support the first cross beam 31 to strengthen the structural strength of the first cross beam 31 . The specific type of the first diagonal brace 32 can be set according to actual needs and is not limited to this. For example, the first diagonal brace 32 can be a beam structure obliquely arranged at the bottom of the first cross beam 31 .

[0060] like Figure 3 As shown, in some embodiments, the first supporting device 3 further includes: a first corner piece 33 and a second corner piece 34, the first corner piece 33 is detachably arranged on the inner wall of the tunnel 200, and an end of the first cross beam 31 away from the first diagonal brace 32 is arranged on the first corner piece 33, the second corner piece 34 is detachably arranged on the inner wall of the tunnel 200, and an end of the first diagonal brace 32 away from the first cross beam 31 is arranged on the second corner piece 34.

[0061] It can be understood that since the first corner piece 33 is detachably arranged on the inner wall of the tunnel 200, and the end of the first beam 31 away from the first diagonal brace 32 is arranged on the first corner piece 33, the first beam 31 can be arranged on the inner wall of the tunnel 200 using the first corner piece 33, and the detachable structure of the first corner piece 33 is used to facilitate the transition installation of the continuous belt conveyor extension section from the unlined section to the lined section of the tunnel 200.

[0062] Since the second corner piece 34 is detachably arranged on the inner wall of the tunnel 200, and the end of the first diagonal brace 32 away from the first cross beam 31 is arranged on the second corner piece 34, the first diagonal brace 32 can be arranged on the inner wall of the tunnel 200 using the second corner piece 34. At the same time, the detachable structure of the second corner piece 34 facilitates the transition installation of the continuous belt conveyor extension section from the unlined section to the lined section of the tunnel 200.

[0063] It should be noted that the removal of the first supporting device 3 only involves the removal between the longitudinal beam 1 and the first cross beam 31 and the removal of the corner piece on the inner wall of the tunnel 200. The operation is simple, which makes the construction efficiency of the continuous belt conveyor extension section higher.

[0064] The first corner piece 33 is used for installing the first cross beam 31 on the inner wall of the tunnel 200 . The specific type of the first corner piece 33 can be set according to actual needs and is not limited thereto.

[0065] The second corner piece 34 is used for installing the first diagonal brace 32 on the inner wall of the tunnel 200 . The specific type of the second corner piece 34 can be set according to actual needs and is not limited thereto.

[0066] like Figure 4 As shown, in some embodiments, the third supporting device 5 includes: a second cross beam 51 and a second diagonal brace 52, the second cross beam 51 is detachably arranged on the inner wall of the lining layer 300 along the width direction of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the second cross beam 51, the length of the second cross beam 51 is less than the length of the first cross beam 31, the second diagonal brace 52 is detachably arranged obliquely on the inner wall of the lining layer 300, and one end of the second diagonal brace 52 away from the inner wall of the lining layer 300 is connected to the end of the second cross beam 51 away from the inner wall of the lining layer 300, and the length of the second diagonal brace 52 is less than the length of the first diagonal brace 32.

[0067] It can be understood that since the second crossbeam 51 is detachably arranged on the inner wall of the lining layer 300 along the width direction of the tunnel 200, and the longitudinal beam 1 is detachably arranged on the second crossbeam 51, the part of the longitudinal beam 1 located at the rear end of the lining trolley 100 can be stably arranged on the inner wall of the lining layer 300 by means of the second crossbeam 51, and at the same time, it is convenient to utilize the detachable structure of the second crossbeam 51 to realize the transition installation of the continuous belt conveyor extension section from the unlined section of the tunnel 200 to the lined section.

[0068] Since the second diagonal brace 52 is detachably arranged obliquely on the inner wall of the lining layer 300, and one end of the second diagonal brace 52 away from the inner wall of the lining layer 300 is connected to the end of the second crossbeam 51 away from the inner wall of the lining layer 300, the second diagonal brace 52 can realize the structural reinforcement of the second crossbeam 51, so that the second crossbeam 51 can more stably support the longitudinal beam 1. At the same time, the detachable structure of the second diagonal brace 52 is utilized to facilitate the transition installation of the continuous belt conveyor extension section from the unlined section to the lined section of the tunnel 200.

[0069] It should be noted that the second cross beam 51 is used to support the part of the longitudinal beam 1 located at the rear end of the lining trolley 100. The specific type of the second cross beam 51 can be set according to actual needs and is not limited to this. For example, the second cross beam 51 can be a beam structure arranged along the width direction of the tunnel 200.

[0070] The second diagonal brace 52 is used to support the second cross beam 51 to strengthen the structural strength of the second cross beam 51. The specific type of the second diagonal brace 52 can be set according to actual needs and is not limited to this. For example, the second diagonal brace 52 can be a beam structure obliquely arranged at the bottom of the second cross beam 51.

[0071] Among them, since the installation dimensions change after the lining layer 300 is set on the inner wall of the tunnel 200, the length of the second crossbeam 51 is set to be smaller than the length of the first crossbeam 31, and the length of the second diagonal brace 52 is set to be smaller than the length of the first diagonal brace 32, so that after the continuous belt conveyor passes through the lining trolley 100, its center distance and installation height can remain unchanged.

[0072] like Figure 4 As shown, in some embodiments, the third supporting device 5 also includes: a third corner piece 53 and a fourth corner piece 54, the third corner piece 53 is detachably arranged on the inner wall of the lining layer 300, and the end of the second cross beam 51 away from the second diagonal brace 52 is arranged on the third corner piece 53, the fourth corner piece 54 is detachably arranged on the inner wall of the lining layer 300, and the end of the second diagonal brace 52 away from the second cross beam 51 is arranged on the fourth corner piece 54.

[0073] It can be understood that since the third corner piece 53 is detachably arranged on the inner wall of the lining layer 300, and the end of the second beam 51 away from the second diagonal brace 52 is arranged on the third corner piece 53, the second beam 51 can be arranged on the inner wall of the lining layer 300 using the third corner piece 53, and the detachable structure of the third corner piece 53 is used to facilitate the transition installation of the continuous belt conveyor extension section from the unlined section of the tunnel 200 to the lined section.

[0074] Since the fourth corner piece 54 is detachably arranged on the inner wall of the lining layer 300, and the end of the second diagonal brace 52 away from the second cross beam 51 is arranged on the fourth corner piece 54, the second diagonal brace 52 can be arranged on the inner wall of the lining layer 300 using the fourth corner piece 54. At the same time, the detachable structure of the fourth corner piece 54 facilitates the transition installation of the continuous belt conveyor extension section from the unlined section to the lined section of the tunnel 200.

[0075] It should be noted that the installation of the second supporting device 4 only involves the installation between the longitudinal beam 1 and the second cross beam 51 and the installation of the corner piece on the inner wall of the lining layer 300, which is simple to operate and makes the construction efficiency of the continuous belt conveyor extension section higher.

[0076] The third corner piece 53 is used for installing the second cross beam 51 on the inner wall of the lining layer 300 . The specific type of the third corner piece 53 can be set according to actual needs and is not limited thereto.

[0077] The fourth corner piece 54 is used for installing the second diagonal brace 52 on the inner wall of the lining layer 300 . The specific type of the fourth corner piece 54 can be set according to actual needs and is not limited thereto.

[0078] like Figure 5 As shown, the embodiment of the present disclosure also proposes a construction method for a continuous belt conveyor extension section adapted for a lining trolley 100. The construction method is based on the structure of the continuous belt conveyor extension section adapted for a lining trolley 100 according to the embodiment of the present disclosure, and includes:

[0079] S1: driving the lining trolley 100 to perform lining operation along the length direction of the tunnel 200, and always using the first first support device 3 at the front end of the lining trolley 100 as the front end support device, and always using the first third support device 5 at the rear end of the lining trolley 100 as the rear end support device;

[0080] S2: When the distance between the lining trolley 100 and the front end support device reaches a first preset distance, the front end support device is removed;

[0081] S3: When the distance between the lining trolley 100 and the rear end supporting device reaches a second preset distance, the third supporting device 5 is installed between the lining trolley 100 and the rear end supporting device.

[0082] It can be understood that since the multiple roller groups 2 are arranged at intervals on the longitudinal beam 1, and the part of the longitudinal beam 1 located at the front end of the lining trolley 100 is detachably arranged on the first supporting device 3, the part of the longitudinal beam 1 located at the lining trolley 100 is slidably arranged on the second supporting device 4, and the part of the longitudinal beam 1 located at the rear end of the lining trolley 100 is detachably arranged on the third supporting device 5, the longitudinal beam 1 can be arranged in the tunnel 200 by utilizing the support of the first supporting device 3, the second supporting device 4 and the third supporting device 5, so as to effectively support the multiple roller groups 2, and then utilize the support and guidance of the multiple roller groups 2 to ensure the normal operation of the continuous belt conveyor.

[0083] At the same time, by utilizing the support cooperation of the second supporting device 4, the longitudinal beam 1 can directly penetrate the lining trolley 100 from the front end of the lining trolley 100 and extend to the rear end of the lining trolley 100, which not only enables the extended section of the continuous belt conveyor to achieve consistency in its center distance and installation height, but also avoids the influence between the disassembly and assembly operations of the roller group 2 and the lining operations of the lining trolley 100. Therefore, while achieving stable operation of the continuous belt conveyor, the lining trolley 100 can also perform lining operations simultaneously, thereby effectively improving the construction efficiency of the tunnel 200 and greatly shortening the construction period.

[0084] It should be noted that when the distance between the lining trolley 100 and the front-end support device reaches the first preset distance, the front-end support device is removed, so that the next first support device 3 becomes the new front-end support device, and when the distance between the lining trolley 100 and the rear-end support device reaches the second preset distance, the third support device 5 is installed between the lining trolley 100 and the rear-end support device, so that the installed third support device 5 becomes the new rear-end support device. Thus, with the continuous lining operation of the lining trolley 100, the first support device 3 is sequentially removed and the third support device 5 is sequentially installed in coordination with the movement of the lining trolley 100, thereby realizing the transitional installation of the continuous belt conveyor extension section from the unlined section of the tunnel 200 to the lined section, thereby effectively improving the construction efficiency of the tunnel 200 and greatly shortening the construction period of the tunnel 200.

[0085] The first preset distance and the second preset distance can be set according to actual needs and are not limited thereto.

[0086] The dismantled first supporting device 3 can be transferred to the front end of the unlined section of the tunnel 200 for recycling, so as to save material cost.
