Description

Technical Field

[0001] The utility model belongs to the technical field of concrete plate production and processing, and more specifically relates to a vertical lifting mechanism and a hoisting device. Background Art

[0002] Aerated concrete board is a new type of lightweight, porous, green and environmentally friendly building material with cement, lime, silica sand and other raw materials as the main raw materials, and different amounts of anti-corrosion treated steel mesh are added according to the structural requirements. It is cured by high temperature, high pressure and steam to produce autoclaved aerated concrete board with porous crystals. Its density is smaller than that of general cementitious materials, and it has unparalleled properties such as good fire resistance, fire prevention, sound insulation, heat insulation and thermal insulation.

[0003] In the current aerated concrete board production line, the mesh cage / mesh needs to be treated with anti-corrosion before being placed in the blank to prevent the mesh cage / mesh from being corroded by the chemical components of the slurry in the model car. Therefore, the anti-corrosion of the steel mesh cage / mesh is a very important process in the entire board circulation process. In the existing mesh cage / mesh anti-corrosion crane, a chain lifting method is usually adopted. Although the chain lifting device has a higher load-bearing capacity, the weight of the saddle frame steel chisel and the mesh cage / mesh attached to the saddle frame seat is not heavy, and there is not much demand on the load-bearing capacity of the lifting equipment. At the same time, the chain hoist requires a larger installation space and will generate a lot of noise during operation, especially when starting or stopping.

[0004] After searching, the application case with Chinese patent publication number CN 212953968 U discloses an anti-corrosion device for aerated concrete plate steel mesh cage. The lifting device in this application includes a winch, a fixed pulley and a steel cable. The winch is arranged on the crossbeam, one end of the steel cable is wound on the winch, the fixed pulley is horizontally arranged on the side wall of the crossbeam, the end of the steel cable away from the winch passes around the fixed pulley and hangs vertically, and the steel cable is connected to the extraction frame. In this application, the mutual cooperation of the steel cable and the winch is used to replace the chain lifting. Although it can reduce the noise during operation, the stability of its lifting needs to be further improved. Utility Model Content

[0036] The utility model is further described below in conjunction with specific embodiments.

[0037] Example 1

[0038] like Figure 1 As shown, a vertical lifting mechanism of this embodiment includes a mounting base 1, on which a lifting motor 2, a synchronization component 3 and a guide member 4 are provided.

[0039] The synchronous assembly 3 is provided with two, which are respectively located at the front and rear sides of the lifting motor 2 (with Figure 1 The lifting motor 2 is used to drive two synchronous components 3 to rotate synchronously at the same time.

[0040] The synchronization component 3 is provided with two winding areas 5, each of which is provided with a traction rope 6, and a guide member 4 is provided on each of the left and right sides of the synchronization component 3. The free end of the traction rope 6 bypasses the corresponding guide member 4 and extends to the bottom of the mounting base 1 for connecting the hoisted object.

[0041] That is, each synchronization component 3 can drive the traction ropes 6 on both sides which are 180° in opposite directions to be curled and wound synchronously. Specifically in this embodiment, the traction ropes 6 are traction steel belts.

[0042] A vertical lifting mechanism of this embodiment adopts a lifting method of winding and curling the traction rope 6, replacing the traditional chain-type lifting method, which can effectively reduce the noise pollution generated during the lifting process and is conducive to saving installation space. In addition, in this embodiment, four traction ropes 6 can form four lifting points, and the four traction ropes 6 are synchronously curled by the same lifting motor 2, which can ensure the stability of the hoisted object during the lifting process.

[0043] Example 2

[0044] This embodiment is an implementation method of the synchronization component 3.

[0045] refer to Figure 2 , Figure 3As shown, a vertical lifting mechanism of this embodiment, the synchronization component 3 includes a synchronization shaft 31, a winding roller 32 and a limit plate 33.

[0046] The synchronous shaft 31 is arranged on the mounting base 1 through a bearing seat, and its end is connected to the output shaft of the lifting motor 2.

[0047] The winding roller 32 is sleeved on the synchronous shaft 31, and two winding rollers 32 are provided. The winding roller 32 and the synchronous shaft 31 can be matched through a keyway to achieve synchronous rotation.

[0048] Two limiting plates 33 are disposed on each winding roller 32 , and the winding roller 32 and the two limiting plates 33 thereon form the above-mentioned winding area 5 .

[0049] At the same time, in order to ensure the smoothness of the winding roller 32 when curling the traction rope 6, the winding roller 32 is cylindrical as a whole.

[0050] A vertical lifting mechanism of the present embodiment can limit the winding of the traction rope 6 within the winding area 5. At the same time, by controlling the distance between the two limit plates 33, the traction rope 6 is wound in a single layer in sequence, which can effectively reduce the fluctuation caused by the misplaced winding of the traction rope 6 and further improve the stability during the lifting operation.

[0051] Example 3

[0052] Since the traction rope 6 is driven by and wound around the winding roller 32 , the end of the traction rope 6 needs to be fixed to the winding roller 32 .

[0053] The conventional operation mode is to provide mutually matching connectors, such as buckles, snap rings, etc., on the outer surface of the winding roller 32 and the end of the traction rope 6. However, this will form a raised part at the connection between the two, thereby affecting the stability of the curling operation.

[0054] To this end, in this embodiment, the specific structure of the winding roller 32 is further optimized to overcome the above problems.

[0055] Specifically, refer to Figure 3 As shown, the winding roller 32 adopts a split design, which includes a first pressure block 321 and a second pressure block 322 distributed up and down; wherein the second pressure block 322 is used to connect with the synchronization shaft 31, and a gap is left between the two pressure blocks for the end of the traction rope 6 to be inserted.

[0056] The first pressing block 321 and the second pressing block 322 are connected by bolts, and the size of the gap is adjusted by the bolts to tighten the end of the traction rope 6.

[0057] A vertical lifting mechanism of this embodiment divides the winding roller 32 into two parts, an upper part and a lower part, and a gap is left between the two parts for the end of the traction rope 6 to be inserted into, so that the upper and lower parts are combined and the traction rope 6 is pressed to form a cylindrical shape, and the surface of the cylindrical shape has no obvious protrusions, so that the curling operation of the traction rope 6 tends to be stable and smooth.

[0058] Example 4

[0059] This embodiment is an implementation method of the guide member 4.

[0060] refer to Figure 4 As shown, the guide member 4 includes a guide shaft 41 and a seat bearing 42 .

[0061] There are two seat bearings 42 , and both ends of the guide shaft 41 are rotatably disposed in the corresponding seat bearings 42 .

[0062] In addition, two stop blocks 43 are provided on the guide shaft 41 , and the traction rope 6 is limited between the two stop blocks 43 .

[0063] The vertical lifting mechanism of this embodiment can change the direction of the traction rope 6 by rotating the guide shaft 41, and can also help reduce the friction between the two, so as to extend the service life of the traction rope 6. At the same time, the two stop blocks 43 can effectively eliminate the interference to the lifting stability caused by the left and right swing of the traction rope 6.

[0064] Example 5

[0065] This embodiment provides a lifting device, including a frame 7 and a vertical lifting mechanism slidably disposed on the frame 7. The vertical lifting mechanism is the vertical lifting mechanism in the above embodiment, and its sliding direction is horizontal.

[0066] refer to Figure 5 , Figure 6 As shown, the frame 7 is connected to the vertical lifting mechanism through a sliding assembly. Specifically, the sliding assembly includes a guide rail 81 and a main pulley 82. The guide rail 81 is arranged at the top of both sides of the frame 7, and the main pulley 82 is arranged at the bottom of the mounting base 1, and the main pulley 82 is clamped on the guide rail 81.

[0067] Of course, the sliding assembly also needs to be connected to a driving mechanism for driving it to slide along the guide rail 81. The driving mechanism here can adopt an existing structure, which will not be described in detail here.

[0068] In addition, in order to further improve the stability and safety of the movement of the entire lifting mechanism, a pair of auxiliary pulleys 83 are further provided at the bottom of the mounting base 1 , and the two auxiliary pulleys 83 are respectively located on both sides of the guide rail 81 .

[0069] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
