Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, specifically to a hoisting device for use in a limited space under a structural slab. Background Technology

[0002] A reverse construction structure generally includes a foundation pit and a structural slab located within the foundation pit. The structural slab and the bottom of the foundation pit form a limited space. During the excavation and construction of the reverse construction structure, steel supports need to be assembled within the limited space. The steel supports are heavy and require mechanical equipment for transportation and adjustment. However, the construction work space is limited, which hinders the operation of large mechanical equipment.

[0003] Chinese patent application number 202410285502.7 discloses a multifunctional integrated rail-type lifting mechanism. Specifically, it discloses a movable frame slidably connected to a fixed rail, a traction mechanism driving the movable frame to slide, a lifting support on the movable frame, universal wheels and a fixed lifting pulley connected to the lifting support via a pivot, and a horizontally movable lifting pulley at the front end of the lifting support. A lifting winch is mounted on the movable frame, with its lifting cable guided sequentially through the universal wheels, the fixed lifting pulley, and the movable lifting pulley. A conversion frame is located at the front end of the lifting support, with steel wire ropes symmetrically connected to both ends of the conversion frame, and the ends of the steel wire ropes connected to ground fixing components. Guide rings are provided at both ends of the lifting device and the basket. This multifunctional integrated rail-type lifting mechanism has the movable frame positioned above the fixed rail. The fixed rail is inconvenient to install on a structural slab and requires a large space for installation, making it unsuitable for use in the limited space below the structural slab. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A hoisting device for use in a confined space under a structural slab includes a track rod, a hoisting mechanism, and multiple hanging mechanisms. Each hanging mechanism is located on the upper surface of the structural slab and is arranged at intervals along the extension direction of the track rod. Each hanging mechanism is provided with a through-plate member, which passes through the structural slab and connects to the track rod, so that the track rod is pressed against the lower surface of the structural slab. The hoisting mechanism is slidably mounted on the track rod.

[0007] As a further improvement to the above technical solution:

[0009] Each structural plate and each through-plate component has a through hole at the corresponding position, and the through-plate component passes through the corresponding through hole.

[0010] The through-plate component is a suspension rope.

[0011] The track rod includes an upper plate, a lower plate, and an intermediate plate. The upper plate and the lower plate are fixedly connected by the intermediate plate to form an I-shaped structure. The upper plate abuts against the lower surface of the structural plate, and the hoisting mechanism slides on the lower plate.

[0012] The upper plate has through holes on both sides of the lower plate, and the middle plate has lifting holes. The through plate component passes through the through holes and the lifting holes.

[0013] The top surface of the lower plate is provided with track grooves on both sides of the middle plate, and the top two sides of the hoisting mechanism are provided with pulleys, which slide in the corresponding track grooves respectively.

[0014] Both ends of the hanging rod are equipped with adjustable support components, which are supported on the upper surface of the structural plate.

[0015] The support assembly includes a support screw and a pad. The support screw passes through the hanging rod and is threadedly connected to the hanging rod. The pad is located at the bottom end of the support screw and is supported on the upper surface of the structural plate. The top end of the support screw is provided with a screwing part.

[0016] The pad is rotatably connected to the support screw.

[0030] Example 1:

[0031] Figures 1 to 3 This invention illustrates an embodiment of a hoisting device for a confined space under a structural slab. The hoisting device in this embodiment includes a track rod 1, a hoisting mechanism 2, and multiple hanging mechanisms 3. Each hanging mechanism 3 is located on the upper surface of the structural slab 4 and is arranged at intervals along the extension direction of the track rod 1. Each hanging mechanism 3 is provided with a through plate 5, which passes through the structural slab 4 and connects to the track rod 1, so that the track rod 1 is pressed against the lower surface of the structural slab 4. The hoisting mechanism 2 is slidably mounted on the track rod 1.

[0032] This hoisting device is used in the confined space under the structural slab. The track rod 1 is suspended on the structural slab 4 by various hanging mechanisms 3 and through plate parts 5, and the track rod 1 is pressed against the lower surface of the structural slab 4, so that the installation structure has good stability and occupies little space. It is suitable for use in the confined space under the structural slab.

[0033] Furthermore, in this embodiment, the hanging mechanism 3 includes a hanging rod 31, which is located on the upper surface of the structural plate 4, and the through plate 5 is hung on the hanging rod 31. During installation, the through plate 5 is passed through the structural plate 4, with its bottom end connected to the track rod 1 and its top end hung on the hanging rod 31, making assembly and disassembly convenient.

[0034] Furthermore, in this embodiment, the structural plate 4 and each through plate member 5 are provided with through holes 41 at their corresponding positions, and the through plate members 5 are inserted into the corresponding through holes 41.

[0035] Furthermore, in this embodiment, the through-plate 5 is a lifting rope, such as a steel wire rope. Preferably, the lifting rope is wound around the hanging rod 31.

[0036] Furthermore, such as Figure 3 As shown, in this embodiment, the track rod 1 includes an upper plate 11, a lower plate 12, and an intermediate plate 13. The upper plate 11 and the lower plate 12 are fixedly connected by the intermediate plate 13 to form an I-shaped structure. The upper plate 11 is pressed against the lower surface of the structural plate 4, and the hoisting mechanism 2 is slidably mounted on the lower plate 12. The upper plate 11 is pressed against the lower surface of the structural plate 4, preventing the track rod 1 from swaying left and right and ensuring good stability.

[0037] Furthermore, in this embodiment, the upper plate 11 has through holes 111 on both sides of the lower plate 12, and the middle plate 13 has lifting holes 131. The plate-through member 5 passes through the through holes 111 and the lifting holes 131. The lifting rope can be connected to the upper plate 11 and the middle plate 13 by passing through the holes, which is convenient.

[0038] Furthermore, in this embodiment, the top surface of the lower plate 12 is provided with track grooves 121 on both sides of the middle plate 13, and the top sides of the hoisting mechanism 2 are provided with pulleys 21, which are respectively slidably placed in the corresponding track grooves 121.

[0039] The hoisting mechanism 2 moves along the track rod 1 via pulley 21 and is used to lift and transport steel supports.

[0040] Furthermore, in this embodiment, the hoisting mechanism 2 can be driven by a motor, which drives the pulley 21 to move along the track groove 121. The hoisting mechanism 2 may include a hoisting component for hoisting the steel support. The hoisting component can be operated by a remote control to hoist and lower the steel support.

[0041] In this embodiment, for example, the operators stand on both sides of the foundation pit below the structural slab 4 and use a remote control to move the entire hoisting mechanism 2. After the steel support is lifted down from the excavation hole by a crane, it is tied by hand with hoisting wire rope and hung on the hoisting mechanism 2. Then, the workers on both sides use the remote control to operate the hoisting mechanism 2 to move the steel support to the designated position. Finally, the steel support is assembled section by section by hand.

[0042] Example 2:

[0043] Figure 4 and Figure 5 This paper illustrates another embodiment of the hoisting device of the present invention for use in a confined space under a structural slab. In this embodiment, both ends of the hanging rod 31 are provided with adjustable support components 6, which are supported on the upper surface of the structural slab 4. Due to the presence of the support components 6, during installation, the hoisting rope can first be passed through the through holes 111 and 131 to connect with the upper plate 11 and the middle plate 13. Then, the hanging rod 31 is passed through the top of the hoisting rope, so that the track rod 1 is suspended on the hanging rod 31 by the hoisting rope. Then, by adjusting the height of the support components 6, the hanging rod 31 is raised as a whole until the upper plate 11 of the track rod 1 is pressed against the lower surface of the structural slab 4. In this way, it is possible to hoist first and then tighten, making the overall installation more convenient.

[0044] Furthermore, in this embodiment, the support assembly 6 includes a support screw 61 and a pad 62. The support screw 61 passes through the hanging rod 31 and is threadedly connected to the hanging rod 31. The pad 62 is located at the bottom end of the support screw 61 and is supported on the upper surface of the structural plate 4. The top end of the support screw 61 is provided with a screwing part 611. By rotating the screwing part 611, the entire hanging rod 31 can be lifted. The structure is simple and the operation is convenient.

[0045] Furthermore, in this embodiment, the pad 62 is rotatably connected to the support screw 61. In this way, the rotation of the screwing part 611 will not cause the pad 62 to rotate, reducing the wear between the pad 62 and the upper surface of the structural plate 4.

[0046] 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.
