Description

Technical Field

[0001] This application relates to the field of shaft construction, and in particular to a working hoisting platform for the conversion and replacement of winches in ultra-deep vertical shafts of railway tunnels. Background Technology

[0002] During railway tunnel construction, vertical shafts are typically excavated to improve the tunnel working environment and increase construction efficiency. Vertical shafts also facilitate material transportation, equipment replacement, and maintenance, providing convenience for construction.

[0003] Once the shaft is constructed and the construction space at the bottom of the shaft is formed, in order to improve the safety and stability of the shaft equipment operation, it is usually necessary to modify and replace the winch. This ensures the smooth progress of the construction process. The modification and replacement process typically involves sending the component to be replaced to the bottom of the shaft, dismantling and adjusting the original equipment at the bottom, and then sending the dismantled and adjusted component out of the shaft.

[0004] Regarding the aforementioned technologies, during the process of converting shafts to hinges and replacing components, the placement and transportation of the components to be replaced and the components after dismantling and adjustment are usually achieved by hoisting a single working platform, resulting in low efficiency in converting shafts to hinges and replacing components. Utility Model Content

[0005] To improve the efficiency of shaft conversion and replacement processes, this application provides a working platform for conversion and replacement of winches in ultra-deep vertical shafts of railway tunnels.

[0006] The technical solution provided in this application for a working hoisting platform used for winch replacement in ultra-deep vertical shafts of railway tunnels adopts the following:

[0007] A working platform for upgrading and replacing winches in ultra-deep vertical shafts of railway tunnels includes multiple working platforms. A connecting mechanism is provided between two adjacent working platforms. The connecting mechanism includes a connecting rope, a connector, and a connecting ring. One end of the connecting rope is installed on one of the working platforms, the connector is installed on the other end of the connecting rope, and the connecting ring is installed on the other working platform. The connector is used to connect with the connecting ring.

[0008] By adopting the above technical solution, the setting of multiple working platforms enables a greater load-bearing capacity to be achieved in a single hoisting operation during the shaft conversion and replacement process. This facilitates the sequential placement and transportation of more components to be replaced and components after dismantling and adjustment, thereby improving the work efficiency of the shaft during the conversion and replacement process. Furthermore, the setting of connectors and connecting rings simplifies the connection structure between adjacent working platforms, making it convenient and quick.

[0009] Optionally, the connector includes a connecting fixing part, a connecting locking part, and a connecting reset part. The connecting locking part is rotatably connected to the connecting fixing part, and the connecting reset part is used to reset the connecting locking part. A connecting hole for cooperating with a connecting lifting ring is provided between the connecting locking part and the connecting fixing part.

[0010] By adopting the above technical solution, when the connecting locking part is pressed to make the connecting hole have a gap for the connecting ring to pass through, the connecting ring can be inserted into the connecting hole and contacted by pressing the connecting locking part to achieve the connection between the connector and the connecting ring, which is convenient and quick.

[0011] Optionally, the reset component includes a reset torsion spring, one end of which is connected to the connection fixing part and the other end of which is connected to the connection locking part.

[0012] By adopting the above technical solution, the reset torsion spring makes the structure of resetting after the connecting locking part rotates simple, convenient and stable.

[0013] Optionally, the connecting fixing part is fixedly connected to the connecting stop part, and the connecting locking part is slidably fitted with the connecting stop block. When the connecting stop block abuts against one side of the connecting stop part in the horizontal direction, the position of the connecting locking part is fixed.

[0014] By adopting the above technical solution, the cooperation between the connecting stop and the connecting block further limits the connection locking part, thereby helping to further ensure the connection stability between the connector and the connecting ring after connection.

[0015] Optionally, the work platform is rotatably connected to a rotating shaft, one end of the connecting rope is fixedly connected to the rotating shaft, and the work platform is provided with a rotating assembly for driving the rotating shaft to rotate. The rotating assembly includes a rotating motor, a rotating worm gear, and a rotating worm. The rotating worm gear is coaxially fixedly connected to the rotating shaft, and the rotating worm is rotatably mounted on the work platform and meshes with the rotating worm gear. The rotating motor is used to drive the rotating worm to rotate.

[0016] By adopting the above technical solution, when the rotating motor drives the worm to rotate, the rotating shaft rotates together with the rotating worm wheel due to the cooperation of the rotating worm and the rotating worm, thereby realizing the adjustment of the length of the connecting rope, which in turn facilitates the adjustment of the distance between two adjacent working platforms. It has strong applicability. At the same time, the self-locking effect between the rotating worm wheel and the rotating worm helps to ensure the stability of the position of the rotating shaft after rotation, which in turn facilitates the stability of the relative position of two adjacent working platforms after the position is adjusted.

[0017] Optionally, a fixed sleeve is fixedly connected to the top of one of the work platforms, and a fixed connecting rod is fixedly connected to the bottom of the adjacent work platform. The fixed connecting rod corresponds to the fixed sleeve and is inserted into the fixed sleeve.

[0018] By adopting the above technical solution, the cooperation between the fixed connecting rod and the fixed sleeve plays a limiting role between two adjacent working platforms, which helps to further ensure the stability of the relative position between the two adjacent working platforms.

[0019] Optionally, one end of the fixed connecting rod that is inserted into the fixed sleeve passes through and slides into the working platform, and the other end of the fixed connecting rod that passes through the fixed sleeve is threaded into a limit plate.

[0020] By adopting the above technical solution, the setting of the limit plate plays a further protective role for the other working platform, making it difficult for the bottom working platform to detach from the top working platform, thus ensuring strong safety.

[0021] Optionally, multiple fixed sleeves and fixed connecting rods are circumferentially distributed around the axis of the working platform.

[0022] By adopting the above technical solution, the setting of multiple fixed sleeves and fixed connecting rods plays a more stable limiting role for the two adjacent working platforms, which makes it easier to fully guarantee the stability of the relative position of the two adjacent working platforms.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The setup of multiple work platforms enables a greater load-bearing capacity to be achieved in a single hoisting operation during the shaft conversion and replacement process. This facilitates the sequential placement and transportation of more components to be replaced and components after dismantling and adjustment, thereby improving the work efficiency of the shaft during the conversion and replacement process.

[0025] 2. When the connecting locking part is pressed to create a gap in the connecting hole for the connecting ring to pass through, the connecting ring is inserted into the connecting hole and pressed against the connecting locking part to achieve the connection between the connector and the connecting ring, which is convenient and quick.

[0026] 3. When the rotating motor drives the worm gear to rotate, the rotating shaft rotates together with the rotating worm wheel due to the cooperation of the rotating worm gear, thereby realizing the adjustment of the length of the connecting rope, which in turn facilitates the adjustment of the distance between two adjacent working platforms, making it highly applicable.

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] This application discloses a working hoisting platform for upgrading and replacing winches in ultra-deep vertical shafts of railway tunnels. (Refer to...) Figure 1 The working platform used for the conversion and replacement of ultra-deep vertical shafts in railway tunnels includes multiple working platforms 1. In this embodiment, the number of working platforms 1 is selected as five, and each working platform 1 is rectangular plate-shaped. When each working platform 1 is in the vertical shaft by the hoisting device, it is distributed along the vertical direction.

[0034] Reference Figure 1 and Figure 2 A connecting mechanism is provided between two vertically adjacent work platforms 1. In this embodiment, the top work platform 1 of the two vertically adjacent work platforms 1 is designated as the first platform 101, and the bottom work platform 1 is designated as the second platform 102. The connecting mechanism includes a connecting rope 2, a connector 3, and a connecting ring 4. A rotating shaft 5 is rotatably connected to the top of the second platform 102. One end of the connecting rope 2 is fixedly connected to the rotating shaft 5. The second platform 102 is also provided with a rotating assembly that drives the rotating shaft 5 to rotate, so as to adjust the length of the connecting rope 2.

[0035] Continue to refer to Figure 1 and Figure 2 The rotating assembly includes a rotating motor 6, a rotating worm gear 7, and a rotating worm 8. The rotating worm gear 7 is coaxially and fixedly connected to the rotating shaft 5. The rotating worm 8 is rotatably mounted on the working platform 1 and meshes with the rotating worm gear 7. The rotating motor 6 is mounted on the top of the second platform 102, and the rotating worm 8 is coaxially and fixedly mounted on the output end of the rotating motor 6, so that the rotating motor 6 drives the rotating worm 8 to rotate, which in turn drives the rotating shaft 5 to rotate around its own axis via the rotating worm gear 7. In this embodiment, both the rotating shaft 5 and the rotating assembly are provided in two sets, respectively located near both sides of the second platform 102.

[0036] Reference Figure 2 and Figure 3Each of the connecting rope 2, connecting head 3, and connecting ring 4 has two corresponding components to one of the rotating shafts 5. The connecting head 3 is fixedly installed at the end of the connecting rope 2 away from the rotating shaft 5, and the connecting ring 4 is fixedly installed at the bottom of the first platform 101. Specifically, the connecting head 3 includes a connecting fixing part 301, a connecting locking part 302, and a connecting reset part. The connecting fixing part 301 is fixedly installed at one end of the connecting rope 2, and the connecting locking part 302 is rotatably installed on the connecting fixing part 301. A closed connecting hole 9 is formed between the connecting locking part 302 and the connecting fixing part 301. When the connecting locking part 302 rotates, a gap is left between the connecting locking part 302 and the connecting fixing part 301, that is, the connecting hole 9 has a notch. When the connecting ring 4 is placed in the connecting hole 9 through the notch, the connection between the first platform 101 and the second platform 102 is realized.

[0037] Continue to refer to Figure 2 and Figure 3 The connection reset component includes a reset torsion spring 303. One end of the reset torsion spring 303 is fixedly connected to the connection fixing part 301, and the other end is connected to the fixed connection locking part 302, so that the connection locking part 302 automatically resets to a state that is always pressed against and fixed to the connection fixing part 301 under the elastic force of the reset torsion spring 303, thereby ensuring the connection stability between the first platform 101 and the second platform 102. To further ensure the connection stability between the first platform 101 and the second platform 102, the connecting fixing part 301 is integrally fixedly connected to the connecting stop part 10, and the connecting locking part 302 is slidably fitted with the connecting stop block 11. When the connecting stop block 11 abuts against one side of the connecting stop part 10 in the horizontal direction, the connecting stop block 11 acts as a blocking force to prevent the connecting locking part 302 from rotating, thereby fixing the position of the connecting locking part 302, which is beneficial to further ensure the connection stability between the first platform 101 and the second platform 102. When the connecting stop block 11 moves to the top of the connecting stop part 10, the connecting stop block 11 releases its blocking and limiting effect on the connecting locking part 302, at which time it is convenient to connect with the connecting lifting ring 4 by rotating the connecting locking part 302.

[0038] Reference Figure 1 and Figure 2 To further ensure the stability of the horizontal position after the two adjacent working platforms 1 are connected, a vertically arranged fixing sleeve 12 is fixedly connected to the top of the second platform 102. In this embodiment, the fixing sleeve 12 is rectangular and has four sleeves distributed circumferentially around the axis of the working platform 1. The first platform 101 has four vertically arranged fixing rods 13 corresponding one-to-one with the fixing sleeves 12. Each fixing rod 13 is fixedly connected to a flange 14. Each fixing rod 13 is fixed to the first platform 101 by bolts that pass through the flange 14 and are threaded into the first platform 101.

[0039] Continue to refer to Figure 1 and Figure 2 Each fixed connecting rod 13 is sequentially inserted into each fixed sleeve 12 and the second platform 102, and slides in cooperation with each fixed sleeve 12 and the second platform 102 to provide a stable limiting effect between the first platform 101 and the second platform 102, i.e., the two adjacent working platforms 1, thereby further ensuring the stability of the relative position between the two adjacent working platforms 1. To further protect the bottom working platform 1 and ensure the safety of the working platform 1, each connecting rod has a limit plate 15 threadedly fitted at one end of the fixed sleeve 12.

[0040] The implementation principle of the working platform for the conversion and replacement of ultra-deep vertical shafts in railway tunnels according to the embodiments of this application is as follows: During the conversion and replacement of vertical shafts, the setting of multiple working platforms 1 facilitates the achievement of a larger load capacity through a single hoisting, thereby facilitating the sequential placement and transportation of more components to be replaced and components after dismantling and adjustment, which is beneficial to improving the working efficiency of the vertical shaft during the conversion and replacement process. In addition, the setting of the connector 3 and the connecting ring 4 makes the connection structure between two adjacent working platforms 1 simple, convenient and fast. Furthermore, the cooperation of the fixed connecting rod 13 and the fixed sleeve 12 plays a limiting role between two adjacent working platforms 1, which is beneficial to further ensure the stability of the relative position between two adjacent working platforms 1.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
