Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of inclined shaft construction equipment, specifically to an inclined shaft moving hoisting device. Background Technology
[0002] During the construction of inclined shaft tunnels, the dismantling of facilities such as steel sections, ventilation ducts, water and gas pipes, and cables faces complex environmental challenges. The dismantling process of inclined shaft tunnel facilities is generally as follows: in the lower inclined shaft, the track needs to be preserved to assist in the subsequent installation of pressure steel pipes, while in the upper inclined shaft, the track and auxiliary structures must be completely dismantled. Currently, the industry mostly uses ordinary winches with simple hoisting platforms for dismantling, or sets up temporary supports in the inclined shaft to fix the equipment for dismantling. This requires frequent relocation, resulting in repeated dismantling and fixing work, which not only increases costs but also affects construction efficiency. Another method is to use a mobile platform that moves along the inclined shaft track, and use a crane on the mobile platform for hoisting and dismantling, using a generator fixed on the mobile platform as power. However, fixed generators are difficult to keep horizontal in the inclined shaft, resulting in poor power supply stability and poor adaptability. Furthermore, due to the steep slope of the inclined shaft (usually 30°~45°), narrow space, and dynamic loads, the traditional moving seats that move along the inclined shaft track are generally moved by traction mechanism without locking mechanism, which makes them prone to slippage and poor stability; or the locking mechanism is fixed on the moving seat, which increases the weight of the moving seat and increases the difficulty of handling and installation. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a mobile hoisting device for inclined shafts that improves construction efficiency, power supply and operational stability, and reduces construction costs and handling and installation difficulties.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A mobile hoisting device for an inclined shaft includes a first movable frame, a second movable frame, and a third movable frame that are detachably hinged to each other in sequence. The bottom of the first movable frame, the second movable frame, and the third movable frame are all provided with a set of traveling wheels for moving along the inclined shaft track. The first movable frame is provided with a swing frame, and the swing frame is provided with a platform for placing an engine. The second movable frame is provided with a crane, and the third movable frame is provided with a locking mechanism for locking onto the inclined shaft track.
[0006] As a further improvement to the above technical solution:
[0007] The top of the swing frame is rotatably connected to the top of the first movable frame, and the placement platform is located at the bottom of the swing frame.
[0008] The swing frame is equipped with a locking mechanism for locking the swing frame to the first movable frame.
[0009] The locking mechanism includes a locking bolt and an arc groove. The arc groove is located on the first movable frame, and the center of the arc groove coincides with the swing center of the swing frame. The locking bolt is located on the swing frame and slides through the arc groove.
[0010] The first movable frame has a first hinge seat at its rear end and the second movable frame has a second hinge seat at its front end. The first hinge seat and the second hinge seat are detachably hinged together by a pin.
[0011] The rear end of the second movable frame is provided with a third hinge seat, and the front end of the third movable frame is provided with a fourth hinge seat. The third hinge seat and the fourth hinge seat are detachably hinged by a pin.
[0012] The second mobile frame includes a mobile base and a hanger. The wheels of the second mobile frame are mounted on the mobile base. The first mobile frame is detachably hinged to the front end of the mobile base. The third mobile frame is detachably hinged to the rear end of the mobile base. The bottom of the hanger is fixed to the mobile base. The crane is mounted on the hanger. The mobile base has an opening in the middle.
[0013] The hanger includes a first support, a second support, and a suspension. The bottom ends of the first and second supports are fixed to the front and rear ends of the movable base, respectively. The suspension is located at the top of the first and second supports, and the crane is mounted on the hanger.
[0014] The second support is a telescopic frame, and the suspension is hinged to the first support and the second support.
[0015] The front end of the suspension is provided with a socket.
[0016] Compared with the prior art, the advantages of this utility model are:
[0017] This utility model discloses a mobile hoisting device for inclined shafts. In use, the device is placed on the inclined shaft track and connected to the traction mechanism. It moves forward and backward along the inclined shaft track via the traction of the traction mechanism. An engine is mounted on the placement platform to provide power to the crane and other equipment. Taking the dismantling of a steel section as an example, during the dismantling of the steel section in the lower inclined shaft, the first, second, and third mobile frames advance sequentially along the inclined shaft track. The bottom beams of the steel section are cut off on both sides, leaving the trolley sleepers and the inclined shaft track inside the inclined shaft. Dismantling is carried out only in the middle section, proceeding from top to bottom. A crane hoist is used for lifting, moving the steel section onto the second mobile frame, and finally transporting it out via the second mobile frame. This inclined shaft mobile hoisting device has several advantages. First, by using the second mobile frame and the crane, it moves along the inclined shaft track to gradually dismantle steel structure sections, ventilation ducts, water and gas pipes, and cables, eliminating the need for repeated disassembly and reassembly due to relocation, thus improving construction efficiency and reducing costs. Second, the engine is mounted on a platform and can swing around the swing center of the swing frame under gravity to maintain a relatively horizontal state, adapting to the inclined shaft and improving the engine's operational stability, thereby enhancing power supply stability. Third, a locking mechanism is installed on the third mobile frame to lock it onto the inclined shaft track. This locking mechanism prevents the first, second, and third mobile frames from slipping during dismantling operations, improving stability. Furthermore, the first, second, and third mobile frames are detachable and hinged, facilitating disassembly, transportation, and installation, reducing the overall weight of the transport and installation on the inclined shaft track, and thus reducing the difficulty of transportation and installation.

[0028] Example 1:
[0029] Figures 1 to 4The first embodiment of the inclined shaft moving hoisting device of this utility model is shown. The inclined shaft moving hoisting device of this embodiment includes a first moving frame 1, a second moving frame 2 and a third moving frame 3 that are detachably hinged from front to back. The bottom of the first moving frame 1, the second moving frame 2 and the third moving frame 3 are all provided with a set of traveling wheels 5 for moving along the inclined shaft track 4. The first moving frame 1 is provided with a swing frame 6, and the swing frame 6 is provided with a placement platform 61 for placing an engine. The second moving frame 2 is provided with a crane 7, and the third moving frame 3 is provided with a locking mechanism 8 for locking onto the inclined shaft track 4.
[0030] In use, the inclined shaft mobile hoisting device is placed on the inclined shaft track 4 and connected to the traction mechanism. It moves forward and backward along the inclined shaft track 4 via the traction of the traction mechanism. The engine is mounted on the placement platform 61 and provides power to the crane 7, etc. Taking the dismantling of the steel structure section as an example, during the dismantling of the steel structure section in the lower inclined shaft, the first moving frame 1, the second moving frame 2, and the third moving frame 3 advance sequentially along the inclined shaft track 4. The bottom beams of the steel structure section are cut off on both sides, leaving the trolley sleepers and the inclined shaft track 4 inside the inclined shaft. Only the middle part is dismantled. The dismantling operation is carried out from top to bottom, using the crane 7 for lifting operations. The steel structure section is lifted onto the second moving frame 2 and finally transported out via the second moving frame 2. This inclined shaft mobile hoisting device has several advantages. First, by using the second mobile frame 2 and the crane 7, it moves along the inclined shaft track 4 to gradually dismantle steel structure sections, ventilation ducts, water and gas pipes, and cables, eliminating the need for repeated disassembly and reassembly due to relocation, thus improving construction efficiency and reducing costs. Second, the engine is mounted on the placement platform 61 and can swing around the swing center of the swing frame 6 under gravity to maintain a relatively horizontal state, adapting to the inclined shaft and helping to improve the engine's operational stability, thereby improving power supply stability. Third, the third mobile frame 3 is equipped with a locking mechanism 8 to lock onto the inclined shaft track 4. This locking mechanism 8 prevents the first mobile frame 1, the second mobile frame 2, and the third mobile frame 3 from slipping during dismantling operations, improving stability. Furthermore, the first mobile frame 1, the second mobile frame 2, and the third mobile frame 3 are detachable and hinged, facilitating disassembly, transportation, and installation, reducing the overall weight of transportation and installation on the inclined shaft track 4, and thus reducing the difficulty of transportation and installation.
[0031] Furthermore, such as Figure 1 As shown, in this embodiment, the top of the swing frame 6 is rotatably connected to the top of the first movable frame 1, and the placement platform 61 is located at the bottom of the swing frame 6. The swing frame 6 swings under the action of gravity, so that the placement platform 61 is in a relatively horizontal state. The placement platform 61 is located at the bottom of the swing frame 6, which facilitates the disassembly and assembly of the engine.
[0032] Furthermore, in this embodiment, the rear end of the first movable frame 1 is provided with a first hinge seat 11, and the front end of the second movable frame 2 is provided with a second hinge seat 21. The first hinge seat 11 and the second hinge seat 21 are detachably hinged together by a pin. The rear end of the second movable frame 2 is provided with a third hinge seat 22, and the front end of the third movable frame 3 is provided with a fourth hinge seat 31. The third hinge seat 22 and the fourth hinge seat 31 are detachably hinged together by a pin. The structure is simple and easy to assemble and disassemble.
[0033] Further, in this embodiment, the second movable frame 2 includes a movable base 23 and a hanger 24. The wheel set 5 of the second movable frame 2 is mounted on the movable base 23. The front end of the first movable frame 1 is detachably hinged to the movable base 23, and the rear end of the third movable frame 3 is detachably hinged to the movable base 23. The bottom of the hanger 24 is fixed to the movable base 23, and the crane 7 is mounted on the hanger 24. An opening 231 is provided in the middle of the movable base 23. Figure 2 As shown, the movable base 23 has an opening 231 in the middle, providing operating space for dismantling steel structure sections, ventilation ducts, water and gas pipes, and cables. Specifically, the movable base 23 is mainly formed by splicing horizontal and vertical bars.
[0034] Furthermore, in this embodiment, the hanger 24 includes a first support 241, a second support 242, and a suspension 243. The bottom ends of the first support 241 and the second support 242 are respectively fixed to the front and rear ends of the movable base 23, and the suspension 243 is disposed at the top ends of the first support 241 and the second support 242. The crane 7 is disposed on the hanger 24. Specifically, in this embodiment, the two ends of the suspension 243 are respectively fixed to the top ends of the first support 241 and the second support 242.
[0035] The process of dismantling the sleepers and inclined shaft track 4 can be as follows: After the mobile hoisting device in this shaft dismantles the steel structure sections, ventilation ducts, water and gas pipes and cables between the inclined shaft tracks 4 from top to bottom, a cantilever crane is installed at the front end of the second mobile frame 2, and the sleepers and inclined shaft track 4 are dismantled by the cantilever crane through the downward movement direction.
[0036] The traveling wheel set 5 is an existing component consisting of axle, wheel body and bearing. The traveling wheel set 5 is used to adapt to travel on the inclined shaft track 4, to achieve reliable travel on a certain slope, and to bear a certain dynamic impact load.
[0037] The locking mechanism 8 is an existing component capable of locking onto the inclined shaft rail 4, such as a rail clamp that can clamp the inclined rail 4 when energized or de-energized; its specific structure will not be described in detail here. The crane 7 can be a conventional electric hoist.
[0038] Example 2:
[0039] Figure 4This paper illustrates a second embodiment of the inclined shaft moving hoisting device of this utility model. The structure of the inclined shaft moving hoisting device in this embodiment is basically the same as that in the first embodiment, except that the swing frame 6 is provided with a locking mechanism 9 for locking the swing frame 6 and the first moving frame 1. In this way, when the engine is in a horizontal state, it can be locked onto the first moving frame 1 by the locking mechanism 9, which helps to maintain an absolutely horizontal state and further improves the stability of the engine.
[0040] Furthermore, in this embodiment, the locking mechanism 9 includes a locking bolt 91 and an arc-shaped groove 92. The arc-shaped groove 92 is disposed on the first movable frame 1, and the center of the arc of the arc-shaped groove 92 coincides with the swing center of the swing frame 6. The locking bolt 91 is disposed on the swing frame 6 and slides through the arc-shaped groove 92. When the locking bolt 91 is loosened, the locking bolt 91 has no restrictive effect on the swing of the swing frame 6, and the swing frame 6 can swing under the action of gravity to adjust the horizontal state of the generator. When the swing frame 6 swings to the point where the generator is in a horizontal state, the locking bolt 91 is tightened to lock the swing frame 6 and the first movable frame 1, thus limiting the generator to a horizontal state.
[0041] Example 3:
[0042] The third embodiment of the inclined shaft moving hoisting device of this utility model has a structure that is basically the same as that of the first or second embodiment, except that the second support 242 is a telescopic frame, and the suspension 243 is hinged to the first support 241 and the second support 242. Thus, the height of the suspension 243 can be adjusted by extending and retracting the telescopic frame to meet the passage requirements of inclined shafts of different sizes. The telescopic frame is a conventional component, such as a component with a double-ended screw and two threaded sleeves connected separately, or a telescopic cylinder, a telescopic hydraulic cylinder, a telescopic electric cylinder, etc.
[0043] Example 4:
[0044] The fourth embodiment of the inclined shaft moving hoisting device of this utility model is basically the same in structure as the first or second embodiment, except that: the front end of the suspension 243 is provided with a socket hole for inserting and installing the cantilever crane, which facilitates the installation of the cantilever crane. Specifically, screws can be provided on the side wall of the socket hole to fix the cantilever crane.
