Description

Technical Field

[0001] This utility model relates to the technical field of track hoisting equipment, specifically to a hoisting device suitable for inclined shafts. Background Technology

[0002] During shield tunnel construction, a large amount of material transportation and various process transitions are involved. After the TBM advances forward, the materials from previous processes need to be dismantled and transported out above ground. Currently, the dismantling, assembly, and hoisting of materials above ground generally rely on manual drilling into the tunnel walls, followed by the use of hand-operated hoists. This method is not only inefficient but also poses safety hazards. In particular, the dismantling and hoisting of materials near the tunnel walls usually requires a large number of personnel, wasting significant human resources. It is also highly dangerous, involves cumbersome procedures, and requires re-drilling after each section is dismantled, consuming too much time and failing to meet the requirements for streamlined construction.

[0003] Chinese patent application number 202422352719.3 discloses a narrow-gauge flatbed crane for mining, comprising a flatbed frame and a lifting boom. The lifting boom is mounted on the upper part of the flatbed frame. At least two sets of wheelsets arranged at intervals are provided at the bottom of the flatbed frame, slidingly connected to the track of the transport roadway. Telescopic outrigger structures are provided on both the front and rear sides of the flatbed frame. A jacking column is provided in the middle of each of the left and right sides of the flatbed frame, symmetrically arranged. A hydraulic pump station and a control panel are also provided on the flatbed frame. An underground power source provides power to the motor of the hydraulic pump station, which in turn provides hydraulic power to the lifting boom, telescopic outrigger structures, and jacking columns. The control panel controls the movement of the lifting boom, telescopic outrigger structures, and jacking columns. This narrow-gauge flatbed crane for mining has the following shortcomings: 1) The lack of a support platform to cooperate with the crane boom makes it inconvenient to place objects; 2) It is difficult to adapt to inclined tracks and is not convenient for lifting operations in inclined tunnels (shafts).

[0026] Example 1: Figure 1 This invention illustrates an embodiment of a hoisting device for inclined shafts. The hoisting device for inclined shafts in this embodiment includes a movable seat 1 that moves along a track. A support frame 2 is provided on one side of the movable seat 1, and a support platform 3 is provided on the other side. A suspension 4 is provided on the top of the support frame 2. The suspension 4 extends to the other side of the movable seat 1. A slide rail 5 is provided on the suspension 4, and a hoisting mechanism 6 is movably mounted on the slide rail 5.

[0027] In use, the movable seat 1 slides on the track at the bottom of the tunnel. After the materials near the tunnel edge are removed, they are hoisted to the placement platform 3 by the lifting mechanism 6, and then pulled out of the tunnel by the movable seat 1. The movable seat 1 can be pulled by a rope or driven by an external traveling mechanism. Furthermore, the lifting mechanism 6 is movable on the slide rail 5, facilitating position adjustment to meet the hoisting requirements of the placement platform 3. This hoisting device, suitable for inclined shafts, has a placement platform 3 corresponding to the position of the lifting mechanism 6, which is not only simple in structure but also convenient for placing objects.

[0028] Furthermore, in this embodiment, the slide rail 5 is arranged laterally, with the lateral direction being perpendicular to the moving direction of the movable seat 1 along the track. The lifting mechanism 6 is easy to adjust its position across the width of the tunnel, meeting the lifting requirements of the platform 3 across the tunnel width.

[0029] Furthermore, in this embodiment, the lifting mechanism 6 includes a lifting frame 61 and a lifting hoist 62. The lifting frame 61 is movably mounted on the slide rail 5, and the lifting hoist 62 is mounted on the lifting frame 61. The lifting hoist 62 can be a manual hoist or an electric hoist.

[0030] Furthermore, in this embodiment, the hanger 61 is provided with a longitudinally arranged longitudinal rail, the longitudinal direction being the same as the moving direction of the movable seat 1. A sliding seat 63 is slidably mounted on the longitudinal rail, and the hoist 62 is suspended on the sliding seat 63. The hoist 62 can move along the longitudinal rail with the sliding seat 63, and can also move along the slide rail 5 (transverse rail) with the hanger 61, thereby increasing the range of movement and adapting to a wider range of lifting requirements.

[0031] Example 2: Figures 2 to 5This paper illustrates another embodiment of the hoisting device of this utility model applicable to inclined shafts. The structure of the hoisting device in this embodiment is basically the same as that in Embodiment 1, except that: the bottom of the movable base 1 is provided with a horizontal adjustment mechanism 7 for adjusting the level of the support platform 3, and the bottom of the horizontal adjustment mechanism 7 is provided with a set of movable wheels 8 that move along the track. When the movable wheels 8 slides on the track at the bottom of the inclined shaft, the level of the support platform 3 can be adjusted by the horizontal adjustment mechanism 7 to keep the support platform 3 in a horizontal state, which facilitates the stable placement of materials.

[0032] Further, in this embodiment, the horizontal adjustment mechanism 7 includes a base plate 71, a first lifting adjustment component 72, and a second lifting adjustment component 73. The bottom end of the first lifting adjustment component 72 is hinged to one end of the base plate 71, and the bottom end of the second lifting adjustment component 73 is fixed to the other end of the base plate 71. The two ends of the movable seat 1 are respectively hinged to the top ends of the first lifting adjustment component 72 and the second lifting adjustment component 73. The movable wheel set 8 is located at the bottom of the base plate 71. When used in the inclined shaft, the second lifting adjustment component 73 faces downwards, and the first lifting adjustment component 72 faces upwards. The first lifting adjustment component 72 is in a retracted state, and the second lifting adjustment component 73 is in an extended state. By adjusting the retraction amount of the first lifting adjustment component 72 and the extension amount of the second lifting adjustment component 73, the levelness of the movable seat 1 and the supporting platform 3 can be adjusted, making operation convenient. Preferably, the first lifting adjustment component 72 and the second lifting adjustment component 73 are telescopic adjustment components, such as cylinders, hydraulic cylinders, or electric cylinders, or telescopic components composed of screws and sleeves. Of course, other existing telescopic components can also be used.

[0033] Furthermore, in this embodiment, a receiving box 74 is provided on the base plate 71, and the receiving box 74 extends out to the other side of the movable seat 1. A feed inlet 741 is provided at the top of the extended portion of the receiving box 74. The feed inlet 741 corresponds to the position of the lifting mechanism 6, facilitating the lifting mechanism 6 to lift materials to the feed inlet 741. The presence of the receiving box 74 increases the carrying capacity; in particular, small materials can be lifted into the receiving box 74, while large materials can be lifted to the receiving platform 3, improving adaptability.

[0034] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the receiving box 74 is provided with a discharge door 75 on at least one side to facilitate the discharge of materials from the receiving box 74. Preferably, one side of the discharge door 75 is hinged to the receiving box 74, and the other side is connected to the receiving box 74 via a door lock.

[0035] Furthermore, in this embodiment, the top of each end of the housing 74 is provided with a support portion 9 for supporting the movable base 1. For example... Figure 2 and Figure 3When on an inclined shaft track, the upper end of the movable seat 1 can be supported on the support part 9 at the upper end of the receiving box 74, and the lower end can be located above the support part 9 at the lower end of the receiving box 74. This not only ensures that the supporting platform 3 is in a horizontal state, but also improves the overall structural support strength. When on a horizontal track, the movable seat 1 can be supported on the support parts 9 at both ends of the receiving box 74, improving overall stability and strength.

[0036] Furthermore, in this embodiment, the top surface of the support portion 9 is spherical.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
