Description

Technical Field

[0001] This utility model relates to the field of underground engineering support technology, and more specifically, to a support device for inclined shafts with large slopes. Background Technology

[0002] An inclined shaft is a shaft with a certain angle of inclination that connects the surface and underground tunnels. It is formed during drilling engineering, and the wellhead is not on the same vertical line as the design target point. Instead, it is offset from the vertical line of the wellhead in a given direction according to human needs. Inclined shaft engineering is a "choke point" project in mine construction. Due to its special location and long service life, the construction of inclined shafts is of great significance in mine construction.

[0003] During the construction of inclined shafts, collapses and roof falls frequently occur due to the instability and damage of the surrounding rock, leading to a series of problems such as casualties, extended construction periods, and increased shaft construction costs. This is especially true in inclined shafts with steep slopes, where the difficulty of loading rock, removing waste rock, and draining water is even more pronounced, posing significant challenges to construction. Existing support methods, such as masonry and cast-in-place concrete, suffer from high labor intensity, unsatisfactory support effects, and high construction costs, making them unsuitable for the support requirements of inclined shafts with steep slopes. Utility Model Content

[0004] To address the shortcomings of existing methods, the purpose of this utility model is to provide a support device for inclined shafts with large slopes, so as to solve the problems of unsatisfactory support effect and high construction cost in inclined shafts with large slopes, and improve the stability and safety of inclined shaft support.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-slope inclined shaft support device includes four sets of fixed legs and crossbeams. Each of the four sets of fixed legs is equipped with a sixth hydraulic cylinder for lifting and lowering. A hollow column sleeve, movable with the sixth hydraulic cylinder, is fitted around the outer side of the sixth hydraulic cylinder, and the top of the sixth hydraulic cylinder is fixedly connected to the top of the inner wall of the hollow column sleeve. The upper ends of two sets of hollow column sleeves are fixedly connected by a longitudinal beam. The front and rear ends of the longitudinal beam are fixedly connected by a telescopic crossbeam. A horizontal top guard plate is provided on the upper side of the crossbeam, and the top guard plate is fixedly connected to the crossbeam by a fourth hydraulic cylinder. Inclined wing guard plates are provided on both the left and right sides of the top guard plate, and the bottom of the wing guard plate is hinged to the crossbeam. A third hydraulic cylinder is provided inside the wing guard plate, and the upper and lower ends of the third hydraulic cylinder are respectively hinged to the wing guard plate and the crossbeam. The two sets of hollow column sleeves are fixedly connected by two sets of connecting plates.

[0007] Furthermore, both sets of crossbeams are provided with end guards on their outer sides. One end of the end guard is hinged to the crossbeam, and a first hydraulic cylinder is provided on the lower side of the end guard. One end of the first hydraulic cylinder is hinged to the end guard, and the other end is hinged to the crossbeam.

[0008] Furthermore, the outer sides of the two sets of hollow column sleeves in the longitudinal direction are provided with side guard plates.

[0009] Furthermore, each of the two sets of connecting plates is fixed with two sets of pins. A main connecting rod is rotatably connected to one set of pins, and a secondary connecting rod is rotatably connected to the other set of pins. The outer ends of the main connecting rod and the secondary connecting rod are hinged to the side guard plate. A fifth hydraulic cylinder is hinged to the connecting plate, and the other end of the main connecting rod is hinged to the output end of the fifth hydraulic cylinder.

[0010] Furthermore, the crossbeam is composed of side beam plates, insertion slots, insertion beams, and a central beam plate. The central beam plate is located in the middle, and side beam plates are provided on both its left and right sides. Insertion slots are opened inside the side beam plates. Insertion beams that are adapted to the insertion slots are fixed at both ends of the central beam plate. The insertion beams are inserted into the insertion slots. A second hydraulic cylinder is provided on the lower side of the connection between the central beam plate and the side beam plates. One end of the second hydraulic cylinder is fixedly connected to the central beam plate, and the other end is fixedly connected to the side beam plate.

[0011] Furthermore, the two longitudinally adjacent sets of central beam plates and side beam plates are all fixedly connected by rib beam plates.

[0012] Furthermore, the bottom of the fixed support leg is equipped with an anti-slip pad, and the bottom of the anti-slip pad is evenly provided with multiple conical protrusions.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model can provide comprehensive support for inclined shafts through the top guard plate, wing guard plate and side guard plate, which improves the support effect of inclined shafts. At the same time, the overall height and width of the device can be adjusted to adapt to inclined shafts of different heights and widths, thereby meeting different support requirements.

[0015] 2. In this utility model, both sets of crossbeams are equipped with end guard plates on their outer sides, which can provide additional support from the front and rear sides of the entire device, thereby increasing the support area and support effect. One end of the end guard plate is hinged to the crossbeam, and a first hydraulic cylinder is provided on the lower side of the end guard plate. One end of the first hydraulic cylinder is hinged to the end guard plate, and the other end is hinged to the crossbeam. The first hydraulic cylinder can adjust the position of the end guard plate to adapt to different support requirements.

[0016] 3. In this utility model, the outer sides of the two sets of hollow column sleeves in the longitudinal direction are provided with side guard plates, which provide support for the side of the inclined shaft. The side guard plates are mainly used to support the sidewall of the inclined shaft, preventing the sidewall from collapsing or sliding due to unstable geological conditions or external forces, thereby enhancing the lateral protection capability of the support device and providing more comprehensive support for the construction of the inclined shaft.

[0017] 4. This utility model, through the extension and retraction of the second hydraulic cylinder, can adjust the relative position between the central beam plate and the side beam plate, thereby achieving length adjustment of the crossbeam. This allows the crossbeam to adapt to inclined shafts of different widths, improving the adaptability of the support device. Simultaneously, the plug-in connection design allows for easy disassembly and assembly of the crossbeam, facilitating transportation and storage, and reducing construction costs.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0027] Example:

[0028] like Figures 1 to 7 As shown, a steep inclined shaft support device includes four sets of fixed outriggers 5 and crossbeams 7. Each of the four sets of fixed outriggers 5 has a sixth hydraulic cylinder 18 fixed to its upper side for lifting and lowering, serving as the foundation of the entire support device. The four sets of fixed outriggers 5 provide stable support. A hollow column sleeve 8, which moves with the sixth hydraulic cylinder 18, is fitted around its outer side. The top of the sixth hydraulic cylinder 18 is fixedly connected to the top of the inner wall of the hollow column sleeve 8. The hydraulic cylinder is used to adjust the height of the support device, and the hollow column sleeve 8 moves with the hydraulic cylinder, protecting the hydraulic cylinder and providing additional support points. The upper ends of two sets of hollow column sleeves 8 are fixedly connected by longitudinal beams 17. The front and rear ends of the longitudinal beams 17 are fixedly connected by retractable crossbeams 7, which connect the front and rear longitudinal beams 17, forming a stable frame. A horizontal top is provided on the upper side of the crossbeams 7. The top support plate 2 provides top support. The top support plate 2 is fixedly connected to the crossbeam 7 via the fourth hydraulic cylinder 11. The fourth hydraulic cylinder 11 is used to adjust the height of the top support plate 2 so that it can fit tightly against the top wall of the inclined shaft. Inclined wing support plates 3 are provided on both the left and right sides of the top support plate 2. The wing support plates 3 are used to provide lateral support. The bottom of the wing support plate 3 is hinged to the crossbeam 7. The inner side of the wing support plate 3 is provided with a third hydraulic cylinder 10, and the upper and lower ends of the third hydraulic cylinder 10 are respectively hinged to the wing support plate 3 and the crossbeam 7. The hinge of the third hydraulic cylinder 10 and the wing support plate 3 can be rotated and adjusted to adapt to different support requirements. The two sets of hollow column sleeves 8 in the longitudinal direction are fixedly connected by two sets of connecting plates 12. This design solves the problems of unsatisfactory support effect and high construction cost of the existing support method in inclined shafts with large slopes.

[0029] In this embodiment, end guard plates 1 are provided on the outer sides of both sets of crossbeams 7, which can provide additional support from the front and rear sides of the whole device, thereby increasing the support area and support effect. One end of the end guard plate 1 is hinged to the crossbeam 7, and a first hydraulic cylinder 6 is provided on the lower side of the end guard plate 1. One end of the first hydraulic cylinder 6 is hinged to the end guard plate 1, and the other end is hinged to the crossbeam 7. The first hydraulic cylinder 6 can adjust the position of the end guard plate 1 to adapt to different support requirements.

[0030] In this embodiment, side guard plates 4 are provided on the outer sides of the two sets of longitudinal hollow column sleeves 8, providing support for the side of the inclined shaft. The side guard plates 4 are mainly used to support the sidewall of the inclined shaft, preventing the sidewall from collapsing or sliding due to unstable geological conditions or external forces, thus enhancing the lateral protection capability of the support device and providing more comprehensive support for the construction of the inclined shaft.

[0031] In this embodiment, two sets of pins are fixed on each of the two sets of connecting plates 12. A main connecting rod 14 is rotatably connected to one set of pins, and a secondary connecting rod 16 is rotatably connected to the other set of pins. The outer ends of both the main connecting rod 14 and the secondary connecting rod 16 are hinged to the side guard plate 4. A fifth hydraulic cylinder 15 is hinged to the connecting plate 12, and the other end of the main connecting rod 14 is hinged to the output end of the fifth hydraulic cylinder 15. By rotating the connecting rod and extending / retracting the fifth hydraulic cylinder 15, the position of the side guard plate 4 can be adjusted so that it can fit tightly against the side wall of the inclined shaft, forming a stable support.

[0032] In this embodiment, the crossbeam 7 is composed of side beam plates 71, insertion slots 72, insertion beams 73, and a central beam plate 74. The central beam plate 74 is located in the middle, with side beam plates 71 on both its left and right sides. Insertion slots 72 are formed inside the side beam plates 71. Insertion beams 73, adapted to the insertion slots 72, are fixed at both ends of the central beam plate 74. The insertion beams 73 are inserted into the insertion slots 72. A second hydraulic cylinder 9 is located below the connection between the central beam plate 74 and the side beam plates 71. One end of the second hydraulic cylinder 9 is fixedly connected to the central beam plate 74, and the other end is fixedly connected to the side beam plate 71. By extending and retracting the second hydraulic cylinder 9, the relative position between the central beam plate 74 and the side beam plates 71 can be adjusted, thereby adjusting the length of the crossbeam 7. This allows the crossbeam 7 to adapt to inclined shafts of different widths, improving the adaptability of the support device. Simultaneously, the insertion connection design allows the crossbeam 7 to be easily disassembled and assembled, facilitating transportation and storage, and reducing construction costs.

[0033] In this embodiment, the two longitudinally adjacent sets of central beam plates 74 and side beam plates 71 are fixedly connected by rib beam plates 75. The rib beam plates 75 act as connectors, tightly fixing the two longitudinally adjacent sets of central beam plates 74 and side beam plates 71 together. Through this fixed connection, the rib beam plates 75 enhance the longitudinal integrity of the two sets of crossbeams 7, making the entire support device form a more stable structure and improving the stability of the support device under stress.

[0034] In this embodiment, an anti-slip pad 19 is installed at the bottom of the fixed support leg 5, and multiple conical protrusions are evenly distributed on the bottom of the anti-slip pad 19. The anti-slip pad 19 is in direct contact with the ground, which can increase the contact area between the device and the ground and improve the stability of the device. At the same time, the conical protrusions can further increase the contact area and friction between the anti-slip pad 19 and the ground, thus playing an anti-slip role and preventing slippage.

[0035] Obviously, each hydraulic cylinder is equipped with a power source such as a hydraulic pump station to enable it to work normally. The structure and principle of the hydraulic cylinder are existing mature technologies, and equipping the hydraulic cylinder with a hydraulic pump station is a standard setting, so it will not be described in detail here.

[0036] The working principle of this type of inclined shaft support device with a large slope:

[0037] In actual use, the support device is first transported to the inclined shaft site, and the four sets of fixed outriggers 5 are placed at the bottom of the inclined shaft to ensure stability. The fixed outriggers 5 provide overall support for the device. According to the slope of the inclined shaft, the sixth hydraulic cylinder 18 is activated, which moves the crossbeam 7 upward to bring the support device to the appropriate height. According to the width of the inclined shaft, the length of the crossbeam 7 is adjusted by the second hydraulic cylinder 9 to bring the device to the appropriate width. Then, the fourth hydraulic cylinder 11 is activated to adjust the height of the top guard plate 2 so that it is close to the top wall of the inclined shaft. The third hydraulic cylinder 10 is activated to adjust the angle of the wing guard plate 3 to provide lateral support. The first hydraulic cylinder 6 is activated to adjust the position of the end guard plate 1 so that it is close to the top wall of the inclined shaft to provide front and rear support. The fifth hydraulic cylinder 15 is activated to adjust the position of the side guard plate 4 through the connecting rod so that it is close to the side wall of the inclined shaft to form side support.

[0038] In summary, this steep-slope inclined shaft support device can effectively provide comprehensive support protection, adapt to inclined shafts of different heights and widths, reduce construction costs, and improve construction safety.

[0039] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
