Description
Technical Field
[0001] This utility model relates to the field of tunnel support material storage technology, and in particular to a tunnel support material storage device. Background Technology
[0002] During tunneling face construction, the efficiency of storage and transportation of support materials directly affects the tunneling progress and construction costs. Currently, the industry commonly uses two main methods for storing support materials: one is to load the support materials onto trucks at the surface and transport them to a storage yard near the construction site, where a fixed storage area is set up; the other is to store the materials at a certain distance from the construction site, either through a dedicated material storage chamber or by expanding a temporary material yard within the construction tunnel. These storage methods, to a certain extent, meet the basic storage requirements for support materials.
[0003] However, existing storage methods have significant limitations. On the one hand, the construction of dedicated material storage chambers or the expansion of material storage chambers within tunnels requires a large investment of manpower and resources for tunnel excavation and support construction. This not only results in long construction times but also incurs high costs. For example, the construction cost of a 10-meter-long dedicated material yard can reach 50,000 yuan. On the other hand, the locations of temporary material yards or dedicated chambers are relatively fixed. As tunneling progresses, the distance between the tunnel face and the material yard continuously increases. Each time support materials are used, multiple transfers from the fixed material yard are required. This process consumes a significant amount of manpower and time, severely impacting the improvement of tunneling efficiency.
[0004] The core issue is that existing storage methods cannot dynamically match the storage location of support materials with the progress of tunneling, resulting in high costs and low transportation efficiency. Therefore, there is an urgent need for a support material storage system that can adjust its position synchronously with the extension of the tunnel face, eliminates the need for additional dedicated material yards, and effectively shortens the transportation distance, in order to solve the problems of high cost, long construction period, and low transportation efficiency in existing technologies. Utility Model Content
[0005] To address the current inability to dynamically match the storage location of support materials with the tunneling progress, resulting in high costs and low transportation efficiency, this utility model provides a tunnel support material storage device.
[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0007] A tunnel support material storage device includes a belt conveyor and a material storage rack. The material storage rack includes a bracket; several supports are detachably mounted on the bottom surface of the bracket; the supports span across the belt conveyor; and the bottom surface of the supports is slidably mounted on the belt conveyor via sliding seats that can move along the belt conveyor. This tunnel support material storage device, by spanning the supports of the material storage rack across the belt conveyor and utilizing sliding seats to achieve the sliding mounting of the material storage rack on the belt conveyor, eliminates the need for additional construction of a dedicated material yard or tunnel widening, significantly reducing construction costs and time. It allows for synchronous adjustment of the material storage position as the tunnel face extends, maintaining a close proximity between the support material and the construction site, significantly reducing labor input and time consumption for material transportation, and effectively solving the problems of high cost, long construction period, and low transportation efficiency in existing technologies.
[0008] Preferably, the belt conveyor includes two spaced longitudinal beams; each end of the longitudinal beam is vertically fixed with a support rod; several crossbeams are arranged between the two longitudinal beams; idler rollers are arranged on the crossbeams; and a sliding seat is slidably mounted on the longitudinal beams, allowing the sliding seat to move along the longitudinal beams. The belt conveyor uses two spaced longitudinal beams as the main support, which, together with the vertically fixed support rods at both ends, forms a stable frame. The crossbeams and idler rollers between the longitudinal beams ensure the conveying function while providing a reliable sliding track for the sliding seat, allowing it to slide stably along the longitudinal beams. This structural design utilizes the original load-bearing frame of the belt conveyor, eliminating the need for additional support structures and further reducing costs. Furthermore, the guiding effect of the longitudinal beams ensures smooth sliding and precise positioning of the material storage rack when adjusting its position with the tunneling face, effectively preventing offset or jamming during sliding. This improves the stability and adjustment efficiency of the entire storage system and, in conjunction with the sliding seat, more efficiently solves the problems of long material transfer distances and inconvenient adjustments in existing technologies.
[0009] Preferably, the support includes a connecting rod; each end of the connecting rod is vertically fixed with a vertical pole; a sliding seat is hinged to the end of the vertical pole away from the connecting rod; and a bracket is detachably mounted on the connecting rod. The support uses a connecting rod and vertically fixed vertical poles to form the main frame. The design of hinged sliding seats at the ends of the vertical poles away from the connecting rod ensures the flexibility of the connection between the support and the sliding seat, allowing the support to move with the belt conveyor. The vertical fixing structure of the connecting rod and the vertical poles also enhances the overall load-bearing capacity, ensuring the stability and reliability of the support materials stored on the bracket. The detachable mounting of the bracket on the connecting rod allows for adjustments in the length and number of brackets according to the specifications of the support materials, further improving the adaptability of material storage. Working in conjunction with the longitudinal beams and sliding seats of the belt conveyor, the entire storage system can dynamically adjust its position with the tunneling face while maintaining structural stability and operational flexibility, more efficiently solving the problems of high material storage costs and inconvenient transportation in existing technologies.
[0010] Preferably, the sliding seat includes a flat plate; a vertical plate is vertically fixed to one end of the flat plate, and a mounting plate is vertically fixed to the other end of the flat plate; two horizontal rollers are rotatably arranged between the vertical plate and the mounting plate; a protrusion is fixedly arranged in the middle of the end of the vertical plate away from the flat plate; a side roller is rotatably arranged between the protrusion and the flat plate; the side roller contacts the outer surface of the longitudinal beam; the horizontal roller contacts the top surface of the longitudinal beam; and the upright is hinged to the flat plate. The sliding seat forms a multi-directional limiting structure for the longitudinal beam by vertically fixing the vertical plate and the mounting plate at both ends of the flat plate, and by rotatably arranging the horizontal roller between the vertical plate and the mounting plate, in conjunction with the side roller between the protrusion of the vertical plate and the flat plate. Among them, the horizontal roller contacts the top surface of the longitudinal beam and the side roller contacts the outer surface of the longitudinal beam, which not only transforms the sliding friction between the sliding seat and the longitudinal beam into rolling friction, but also significantly reduces the resistance when adjusting the position of the material storage rack, making the sliding smoother and less labor-intensive, but also ensures that no lateral deviation or swaying occurs during the sliding process through multi-directional contact, thus improving the sliding stability. The design of the uprights being hinged to the flat plate further enhances the flexibility of the connection with the support, making it easier to adapt to the roadway environment when dynamically adjusted with the tunnel face, effectively ensuring the efficiency and reliability of position adjustment, and optimizing the material transfer efficiency in synergy with the longitudinal beam, support and other components.
[0011] Preferably, a hinge pin is fixedly installed at the end of the upright; a through hole is provided on the flat plate; the hinge pin is located within the through hole; a radial through hole is provided on the hinge pin; and a cotter pin is provided within the radial through hole. The hinge pin at the end of the upright passes through the through hole of the flat plate, and together with the cotter pin in the radial through hole of the hinge pin, a detachable hinge structure is formed. This ensures the reliability of the connection between the bracket and the sliding seat, and the quick installation and removal of the cotter pin allows for convenient disassembly and assembly of the two components. This facilitates flexible adjustment of the number of brackets or maintenance and replacement of components according to construction needs. At the same time, the cooperation between the hinge pin and the through hole provides a stable rotation fulcrum for the upright. Combined with the limiting effect of the cotter pin, it prevents loosening or detachment at the hinge, so that the connection between the sliding seat and the bracket satisfies both rotational flexibility and structural stability, further improving reliability. Together with the horizontal rollers and side rollers of the sliding seat, it ensures the efficient operation of the material storage rack.
[0012] Preferably, the vertical plate has a threaded hole on the side of the longitudinal beam; a screw is threaded into the threaded hole. The screw can be used to press against the side of the longitudinal beam to fix the position of the sliding seat, facilitating the placement and removal of support materials.
[0013] Preferably, the bracket includes a H-shaped base frame; several stops are provided on the H-shaped base frame; a mounting box is bolted to the H-shaped base frame; the mounting box is a shell-like structure with an open top. The bracket uses the H-shaped base frame as its basic load-bearing structure, possessing strong overall rigidity and load-bearing capacity, and can stably support various support materials; the stops on the base frame form a protective barrier, effectively preventing materials from tipping over or falling during storage or movement with the system, thus improving storage safety; the bolted, open-top shell-like mounting box not only facilitates quick assembly and disassembly to accommodate the storage needs of small accessories of different sizes, but also works in conjunction with the H-shaped base frame to achieve classified storage of materials, avoiding confusion caused by mixed storage.
[0014] Preferably, a fixed rod and a return roller are fixedly installed between the support rods on the same side of the two longitudinal beams; the return roller is located on one side of the fixed rod. The fixed rod, which is fixedly installed between the support rods on the same side of the two longitudinal beams, can enhance the connection strength of the support rods on both sides of the belt conveyor and improve the stability of the overall frame; while the return roller located on one side of the fixed rod can provide support and guidance for the return section of the belt.
[0015] As can be seen from the above technical solutions, the advantages of this utility model include: the roadway support material storage device sets the support of the material storage rack across the belt conveyor and uses a sliding seat to realize the sliding setting of the material storage rack on the belt conveyor. It eliminates the need for additional construction of a special material yard or roadway expansion, which greatly reduces construction costs and construction period. It can adjust the material storage position synchronously with the extension of the tunnel face, always maintaining the close distance between the support material and the construction site, significantly reducing the manual input and time consumption of material transportation, and effectively solving the problems of high cost, long construction period and low transportation efficiency in the prior art.

Detailed Implementation
[0024] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0025] like Figure 1 As shown, a roadway support material storage device includes a belt conveyor 1 and a material storage rack 2. The material storage rack 2 includes a bracket 201. Several supports 202 are detachably provided on the bottom surface of the bracket 201. The supports 202 are straddling the belt conveyor 1. The bottom surface of the supports 202 is slidably mounted on the belt conveyor 1 through a sliding seat 203, which can move along the belt conveyor 1.
[0026] This roadway support material storage device places the material storage rack 2's support 202 across the belt conveyor 1 and uses the sliding seat 203 to slide the material storage rack 2 on the belt conveyor 1. This eliminates the need for additional construction of a dedicated material yard or roadway expansion, significantly reducing construction costs and time. It can adjust the material storage position synchronously with the extension of the tunnel face, always maintaining a close distance between the support material and the construction site, significantly reducing the manual input and time consumption for material transportation, and effectively solving the problems of high cost, long construction period and low transportation efficiency in existing technologies.
[0027] like Figure 2As shown, the belt conveyor 1 includes two spaced longitudinal beams 101; each end of the longitudinal beam 101 is vertically fixed with a support rod 102; several crossbeams 103 are arranged between the two longitudinal beams 101; idler rollers 104 are arranged on the crossbeams 103; a sliding seat 203 is slidably arranged on the longitudinal beam 101, and the sliding seat 203 can move along the longitudinal beam 101. A fixed rod 105 and a return roller 106 are fixedly arranged between the support rods 102 on the same side of the two longitudinal beams 101; the return roller 106 is arranged on one side of the fixed rod 105.
[0028] The belt conveyor 1 uses two spaced longitudinal beams 101 as the main support, which, together with the vertically fixed support rods 102 at both ends, form a stable frame. The crossbeams 103 and idler rollers 104 between the longitudinal beams 101 ensure the conveying function while providing a reliable sliding track for the sliding seat 203, allowing the sliding seat 203 to slide stably along the longitudinal beams 101. This structural design utilizes the original load-bearing frame of the belt conveyor 1, eliminating the need for additional support structures and further reducing costs. Furthermore, the guiding effect of the longitudinal beams 101 ensures that the material storage rack 2 slides smoothly and is accurately positioned when adjusting its position with the tunneling face, effectively preventing offset or jamming during the sliding process. This improves the stability and adjustment efficiency of the entire storage system and, in conjunction with the sliding seat 203, more efficiently solves the problems of long material transfer distances and inconvenient adjustments in existing technologies. The fixing rod 105, which is fixedly installed between the support rods 102 on the same side of the two longitudinal beams 101, can enhance the connection strength of the support rods 102 on both sides of the belt conveyor 1 and improve the stability of the overall frame; while the return roller 106, which is installed on one side of the fixing rod 105, can support and guide the return section of the belt.
[0029] like Figure 3 and Figure 4 As shown, the bracket 201 includes a H-shaped base frame 2011; the H-shaped base frame 2011 is provided with two sets of six stops 2012, with the two sets of stops 2012 respectively located at both ends of the H-shaped base frame 2011, and the three stops 2012 in each set are spaced apart; a mounting box 2013 is bolted to the H-shaped base frame 2011; the mounting box 2013 is a shell shape with an opening at the top. The mounting box 2013 is placed between four of the stops 2012, with the four stops 2012 respectively located at the corners of the mounting box 2013.
[0030] The bracket 201 uses a rectangular base frame 2011 as its basic load-bearing structure, which has strong overall rigidity and load-bearing capacity, and can stably support various support materials. Several baffles 2012 on the base frame can form a protective barrier to effectively prevent materials from tipping over and falling during storage or when moving with the system, thus improving storage safety. The shell-shaped mounting box 2013 with an upper opening set by bolts not only facilitates quick assembly and disassembly to meet the storage needs of small parts of different sizes, but also works with the rectangular base frame 2011 to achieve classified storage of materials and avoid confusion caused by mixed storage.
[0031] like Figure 5 and Figure 6 As shown, the bracket 202 includes a connecting rod 2021; both ends of the connecting rod 2021 are vertically fixed with uprights 2022; the end of the upright 2022 away from the connecting rod 2021 is hinged to a sliding seat 203; the bracket 201 is detachably mounted on the connecting rod 2021. The support 202 adopts a main frame consisting of a connecting rod 2021 and vertically fixed uprights 2022 at both ends. The end of the upright 2022 away from the connecting rod 2021 is hinged to a sliding seat 203. This design ensures the flexibility of the connection between the support 202 and the sliding seat 203, allowing the support 202 to move with the belt conveyor 1. The vertical fixing structure of the connecting rod 2021 and the upright 2022 also enhances the overall load-bearing capacity, ensuring the stability and reliability of the support materials stored on the bracket 201. The bracket 201 is detachably mounted on the connecting rod 2021, allowing the length of the bracket 201 and the number of supports 202 to be increased or decreased according to the specifications of the support materials. This further improves the adaptability of material storage. Working in conjunction with the longitudinal beam 101 and the sliding seat 203 of the belt conveyor 1, the entire storage system can dynamically adjust its position with the tunneling face while maintaining structural stability and operational flexibility. This more efficiently solves the problems of high material storage costs and inconvenient transportation in existing technologies.
[0032] The sliding seat 203 includes a flat plate 2031; a vertical plate 2032 is vertically fixed to one end of the flat plate 2031, and a mounting plate 2033 is vertically fixed to the other end of the flat plate 2031; two horizontal rollers 2034 are rotatably arranged between the vertical plate 2032 and the mounting plate 2033; a protrusion 2035 is fixedly arranged in the middle of the end of the vertical plate 2032 away from the flat plate 2031; a side roller 2036 is rotatably arranged between the protrusion 2035 and the flat plate 2031; the side roller 2036 contacts the outer side of the longitudinal beam 101; the horizontal rollers 2034 contact the top surface of the longitudinal beam 101; and the upright 2022 is hinged to the flat plate 2031. A hinge shaft 2023 is fixedly arranged at the end of the upright 2022; a through hole is provided on the flat plate 2031; the hinge shaft 2023 is arranged in the through hole; a radial through hole 2024 is provided on the hinge shaft 2023; and a cotter pin is arranged in the radial through hole 2024.
[0033] The sliding seat 203 is vertically fixed to the vertical plate 2032 and the mounting plate 2033 at both ends of the flat plate 2031. A rotating horizontal roller 2034 is set between the vertical plate 2032 and the mounting plate 2033, which, together with the side roller 2036 between the protrusion 2035 of the vertical plate 2032 and the flat plate 2031, forms a multi-directional limiting structure for the longitudinal beam 101. The horizontal roller 2034 contacts the top surface of the longitudinal beam 101, and the side roller 2036 contacts the outer surface of the longitudinal beam 101. This converts the sliding friction between the sliding seat 203 and the longitudinal beam 101 into rolling friction, which greatly reduces the resistance when adjusting the position of the material storage rack 2, making the sliding smoother and less strenuous. The multi-directional contact also ensures that no lateral deviation or wobbling occurs during the sliding process, thus improving the sliding stability. The design of the upright 2022 hinged to the flat plate 2031 further enhances the flexibility of the connection with the bracket 202. The hinge pin 2023 at the end of the upright 2022 passes through the through hole of the flat plate 2031. Together with the cotter pin in the radial through hole 2024 of the hinge pin 2023, a detachable hinge structure is formed. This ensures the reliability of the connection between the bracket 202 and the sliding seat 203. The quick removal and installation of the cotter pin allows for convenient disassembly and assembly of both components, facilitating flexible adjustment of the number of brackets 202 or maintenance and replacement of parts according to construction needs. Simultaneously, the engagement of the hinge pin 2023 with the through hole provides a stable rotation fulcrum for the upright 2022. Combined with the limiting effect of the cotter pin, it prevents loosening or detachment at the hinge, ensuring that the connection between the sliding seat 203 and the bracket 202 satisfies both rotational flexibility and structural stability, further enhancing reliability. Together with the horizontal roller 2034 and side roller 2036 of the sliding seat 203, it ensures the efficient operation of the material storage rack 2.
[0034] In order to fix the position of the sliding seat 203 on the belt conveyor 1 and facilitate the loading and unloading of support materials, the vertical plate 2032 is provided with a threaded hole 2037 on the side of the longitudinal beam 101; a screw 2038 is provided in the threaded hole 2037.
[0035] In other alternative embodiments, a slide rail is fixedly installed on the outer side of the frame of the belt conveyor 1, and the slide rail is fixed to the roadway floor. The sliding seat 203 is slidably mounted on the slide rail. In this embodiment, the interference of the belt conveyor 1 with the material storage rack 2 can be reduced, but it occupies a large volume, which is especially inconvenient for personnel to operate when working in the roadway.
[0036] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
