Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a building construction hoisting device. Background Technology

[0002] Building construction refers to the construction of houses and other buildings on land where infrastructure has been completed, including residential buildings, industrial plants, commercial buildings, office buildings, and other specialized buildings. During the building construction process, materials needed for construction need to be hoisted to carry out the corresponding construction work. Currently, most existing building material hoisting is achieved using winches. Workers first place the materials in a material silo, and then the materials are hoisted to the building construction location using steel cables on the winch.

[0003] A patent search revealed a document titled "A Building Lifting Device" (publication number "CN221370398U"). This device uses two sets of motor housings to lift a material container. However, this design cannot guarantee that the two motors will rotate synchronously, potentially causing the container to tilt during lifting and posing a safety hazard. Therefore, this invention designs a building lifting device to address these issues. Utility Model Content

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0024] A preferred embodiment of the building hoisting device provided by this utility model is, for example... Figures 1 to 4 As shown: A building hoisting device includes a support 1; sliding blocks 2 slidably disposed on the left and right sides of the top of the support 1; a rotating shaft 3 rotatably disposed on the lower end of the sliding blocks 2, and a take-up roller 4 is fixedly sleeved on the outside of the rotating shaft 3; a steel cable 5 fixed on the outside of the take-up roller 4, and a hook 6 fixed on the bottom of the steel cable 5; a box 7 disposed inside the support 1, and lifting rings 8 fixed on the left and right sides of the top of the box 7; and a drive assembly 9 assembled on the outside of the support 1, which can control the rotating shaft 3 to rotate in conjunction with the take-up roller 4.

[0025] The drive assembly 9 includes a first motor 901 fixed on the top right side of the bracket 1; a rotating rod 902 fixed on the left side of the first motor 901, the rotating rod 902 passing through the slide block 2 and being rotatably connected to the bracket 1; a worm gear 903 slidably disposed on the left and right sides outside the rotating rod 902; and a worm wheel 904 with gear teeth meshing at the bottom of the worm gear 903, the worm wheel 904 being fixedly sleeved on the outside of the rotating shaft 3.

[0026] It should be noted that existing building hoisting devices still have certain shortcomings in actual use. They cannot hoist the box in a stable state, which can cause the box to tilt during hoisting and create safety hazards.

[0027] In this embodiment, the worker first puts the material into the box 7, then places the box 7 at the lower end of the bracket 1, hooks the hook 6 onto the lifting ring 8, and then turns on the first motor 901. The first motor 901 drives the rotating rod 902 to drive the worm gear 903 and the worm wheel 904 to rotate, which in turn causes the worm wheel 904 to drive the rotating shaft 3 to drive the winding roller 4 to wind up the steel cable 5. The winding steel cable 5 drives the hook 6 to drive the lifting ring 8 and the box 7 to be lifted. In this way, the two winding rollers 4 are in a state of synchronous rotation, thereby raising and lowering the box 7 in a horizontal state.

[0028] In a further preferred embodiment of this utility model, a protective component 10 is assembled inside the box body 7 and the support 1. The protective component 10 can prevent the box body 7 from shaking during the lifting process. The protective component 10 includes a sliding plate 1001 slidably disposed inside the support 1; a first threaded hole 1002 integrally disposed at the four corners inside the sliding plate 1001; and a second threaded hole 1003 integrally disposed at the four corners inside the box body 7. The second threaded hole 1003 is threaded with a screw pin 1004. The first threaded hole 1002 and the second threaded hole 1003 are designed to correspond to each other one by one. The screw pin 1004 and the second threaded hole 1003 are connected by threads for disassembly and assembly.

[0029] In this embodiment, when the box 7 is placed inside the bracket 1, the first threaded hole 1002 and the second threaded hole 1003 are first overlapped, and then the screw 1004 is sequentially threaded to the second threaded hole 1003 and the first threaded hole 1002, so that the box 7 and the slide plate 1001 are firmly connected. When the box 7 is lifted, the box 7 drives the slide plate 1001 to move along the longitudinal direction of the bracket 1, and the slide plate 1001 restricts the shaking of the box 7 when it is lifted. Example 2

[0030] Based on Embodiment 1, a preferred embodiment of the building hoisting device provided by this utility model is as follows: Figures 1 to 4As shown: A displacement assembly is provided inside the bracket 1. The displacement assembly can move two slides 2 along the lateral direction of the bracket 1. The displacement assembly includes a second motor 11 fixed to the upper left side of the bracket 1; a connecting rod 12 fixed to the right side of the second motor 11. The connecting rod 12 rotatably passes through the bracket 1 and is threaded through the slide 2. The left slide 2 and the connecting rod 12 are designed with a left-hand threaded connection, and the right slide 2 and the connecting rod 12 are designed with a right-hand threaded connection. A limiting rod 13 is fixed to the front of the top of the bracket 1. The limiting rod 13 slides through the slide 2. The limiting rod 13 and the connecting rod 12 are designed to be parallel to each other. A controller 14 is fixed to the outer wall of the bracket 1. The controller 14 is connected to the first motor 901 and the second motor 11 through wires.

[0031] In this embodiment, depending on the length of the box 7, the operator can turn on the second motor 11, which drives the connecting rod 12 to rotate. Through the design of the connecting rod 12 and the slide 2 rotating threadedly, the two slides 2 are in a state of moving towards or away from each other along the lateral direction of the limiting rod 13. The slides 2 drive the worm gear 904 to move the worm 903 along the direction of the rotating rod 902, so that the spacing between the two hooks 6 can be matched with the box 7 of different lengths, ensuring the verticality of the steel cable 5 when in use.

[0032] In summary, this application, through its mechanical linkage design, prevents tilting during box lifting, ensuring stability and improving safety during use. The protective design prevents swaying during lifting, further enhancing safety. Furthermore, the adjustable design allows the hook to be matched with boxes of different lengths, ensuring verticality during cable lifting and significantly improving stability during lifting.
