Abstract
Description
Technical Field
[0001] This utility model relates to the field of material hoisting technology, specifically to a material hoisting machine for building construction. Background Technology
[0002] Construction material hoists are vertical material transport equipment with stable structure and diverse load capacity, which can efficiently and safely meet the material transport needs of different building heights.
[0003] Traditional construction material hoists have fixed and limited space in their cage or derrick structures, making it difficult to place long tubular materials stably. These materials are prone to shaking, collisions, or even slipping during the hoisting process. Furthermore, these hoists lack dedicated fixing devices for long tubular materials, making it impossible to effectively constrain their position. Therefore, a new construction material hoist is proposed. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that the cage or derrick structure of traditional construction material hoists cannot effectively restrain long tubular materials. This utility model provides a construction material hoist.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:
[0006] A material hoist for construction includes a base, a lifting mechanism with lifting function on the top of the base, a support plate on the top of the base, guardrail assemblies on both sides of the top of the support plate, the two sets of guardrail assemblies being mirror-distributed, two sets of side rail assemblies for clamping tubular materials in the middle of the two sets of guardrail assemblies, and extrusion assemblies for squeezing the side rail assemblies to clamp the tubular materials on both sides of the support plate, and a protective rod assembly on top of each set of side rail assemblies.
[0007] Furthermore, the lifting mechanism includes a bending plate, which is fixedly installed on the top of the base. A strip-shaped hole is opened on the side wall of the bending plate, and a lead screw is movably installed inside the strip-shaped hole. A servo motor for driving the lead screw to rotate is fixedly installed on the top of the bending plate. Limiting grooves are respectively opened on the two symmetrical sides inside the strip-shaped hole. A lifting block is threadedly connected to the lead screw. The two protrusions on both sides of the lifting block are movably installed inside the corresponding limiting grooves. The lifting block is fixedly connected to the bearing plate.
[0008] Furthermore, the guardrail assembly includes horizontal bars, with horizontal bars respectively provided on both sides above the support plate. Several evenly distributed vertical bars are fixedly installed at the bottom of each horizontal bar, and each vertical bar is fixedly installed on the top of the support plate. An arc-shaped groove is provided on the side wall of each vertical bar.
[0009] Furthermore, the side rail assembly includes railings, with two rows of equidistant railings arranged between two horizontal bars. Each railing has an arc-shaped groove on both sides. The top of the support plate has a strip groove on both sides. Two long bars are fixedly installed inside each strip groove. An I-shaped block is fixedly installed at the bottom of each railing. Each I-shaped block is movably installed inside the adjacent strip groove. A threaded short rod is fixedly installed at the bottom of each I-shaped block. A nut is threaded onto each threaded short rod. A bent rod is fixedly installed on the side wall of each railing.
[0010] Furthermore, the extrusion assembly includes blocks, with two blocks fixedly installed on each side of the support plate. A threaded rod is movably installed between each pair of adjacent blocks. A servo motor for driving the corresponding threaded rod to rotate is fixedly installed on the side wall of each of the two blocks adjacent to the bending plate. A moving block is threadedly connected to each threaded rod. Slide grooves are opened on both sides of the support plate. A slider is fixedly installed on the side wall of each moving block. Each slider is movably installed inside the slide groove. An extrusion block is fixed on the side wall of each moving block.
[0011] Furthermore, the guardrail assembly includes a strip frame, with strip frames respectively set above the two rows of railings. A positioning block is fixedly installed on the top of each railing, and each positioning block is movably installed inside the adjacent strip frame. Threaded grooves are opened at both ends of the top of each crossbar, and bolts are threaded to both ends of each strip frame. The tail end of each bolt is threaded to the inside of the adjacent threaded groove.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This utility model controls the lifting mechanism to lower the support plate to its lowest position, then disassembles the two sets of guardrail assemblies, and then places the tubular material on top of the support plate, so that both ends of the tubular material pass through the two sets of side rail assemblies. Then, the two sets of extrusion assemblies are controlled to clamp and fix the tubular material in place by the two sets of side rail assemblies.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] like Figure 1-5 As shown, a material hoist for construction includes a base 1, and a lifting mechanism 2 with lifting function is provided on the top of the base 1. Figure 1 , 2 As shown in Figure 4, specifically, the lifting mechanism 2 includes a bending plate 201. The bending plate 201 is fixedly installed on the top of the base 1. A strip-shaped hole 202 is opened on the side wall of the bending plate 201. A lead screw 203 is movably installed inside the strip-shaped hole 202. A servo motor 204 for driving the lead screw 203 to rotate is fixedly installed on the top of the bending plate 201. Limiting grooves 205 are respectively opened on the two symmetrical sides inside the strip-shaped hole 202. A lifting block 206 is threadedly connected to the lead screw 203. The two protrusions on both sides of the lifting block 206 are movably installed inside the corresponding limiting grooves 205. The lifting block 206 is fixedly connected to the bearing plate 3.
[0025] More specifically, by starting the servo motor 204, the servo motor 204 can drive the lead screw 203 to reciprocate at a preset angle and speed. The reciprocating rotation of the lead screw 203 can cause the lifting block 206 to rise and fall. The rise and fall of the lifting block 206 then drives the bearing plate 3 to rise and fall synchronously.
[0026] A support plate 3 is provided above the base 1, and guardrail assemblies 4 are respectively provided on both sides of the top of the support plate 3. The two sets of guardrail assemblies 4 are distributed in a mirror image. Figure 1 , 4 As shown, specifically, the guardrail assembly 4 includes a horizontal bar 401. Horizontal bars 401 are respectively provided on both sides above the bearing plate 3. Several evenly distributed vertical bars 402 are fixedly installed at the bottom of each horizontal bar 401. Each vertical bar 402 is fixedly installed on the top of the bearing plate 3. An arc-shaped groove 403 is opened on the side wall of each vertical bar 402.
[0027] More specifically, the guardrail structure composed of horizontal bars 401 and vertical bars 402 can prevent building materials placed on the surface of the bearing plate 3 from falling when being lifted, and the arc groove 403 can also play an auxiliary role in clamping and fixing the tubular materials later.
[0028] Two sets of side railing assemblies 5 for clamping tubular materials are provided between the two sets of guardrail assemblies 4, such as Figure 1, 3 As shown in Figures 4 and 5, specifically, the side rail assembly 5 includes railings 501, with two rows of equally spaced railings 501 arranged between two horizontal bars 401. Each railing 501 has an arc-shaped groove 502 on both sides. The top of the bearing plate 3 has a strip groove 503 on both sides. Two long bars 504 are fixedly installed inside each strip groove 503. An I-shaped block 505 is fixedly installed at the bottom of each railing 501. Each I-shaped block 505 is movably installed inside the adjacent strip groove 503. A threaded short rod 506 is fixedly installed at the bottom of each I-shaped block 505. A nut 507 is threadedly connected to each threaded short rod 506. A bent rod 508 is fixedly installed on the side wall of each railing 501.
[0029] More specifically, if it is necessary to lift the tubular material, place the tubular material on top of the bearing plate 3, so that both ends of the tubular material pass through the middle of each of the two adjacent arc-shaped grooves 502. At this time, rotate each threaded short rod 506 to prevent each I-shaped block 505 from being fixed inside the corresponding strip groove 503. If it is not necessary to lift the tubular material, adjust the distance between each of the two adjacent railings 501 appropriately. When each railing 501 moves, it drives the I-shaped block 505 connected to it to slide synchronously inside the corresponding strip groove 503. Then, rotate each nut 507 to fix the corresponding I-shaped block 505 in the current position, thereby fixing each I-shaped block 505 in the current position to serve as a guardrail.
[0030] On both sides of the bearing plate 3, there are extrusion components 6 for clamping the tubular material by extruding the side rail assembly 5, such as... Figure 1 , 3 As shown in Figures 4 and 5, specifically, the extrusion assembly 6 includes blocks 601. Two blocks 601 are fixedly installed on both sides of the bearing plate 3. A threaded rod 602 is movably installed between each pair of adjacent blocks 601. A servo motor 603 for driving the corresponding threaded rod 602 to rotate is fixedly installed on the side wall of the two blocks 601 adjacent to the bending plate 201. A moving block 604 is threadedly connected to each threaded rod 602. Slide grooves 605 are opened on both sides of the bearing plate 3. A slider 606 is fixedly installed on the side wall of each moving block 604. Each slider 606 is movably installed inside the slide groove 605. An extrusion block 607 is fixed on the side wall of each moving block 604.
[0031] More specifically, when the tubular material is placed on top of the support plate 3, and both ends of the tubular material pass through the middle of each of the two adjacent arc-shaped grooves 502, the servo motor 603 is started. After the servo motor 603 is started, it can drive the threaded rod 602 to reciprocate at a preset angle and speed. The reciprocating rotation of the threaded rod 602 can drive the moving block 604 and the pressing block 607 to move linearly. The pressing block 607 pushes the adjacent bending rod 508, so that each railing 501 moves closer to the lifting mechanism 2, effectively clamping the tubular material.
[0032] Each side rail assembly 5 is equipped with a protective bar assembly 7 above it, such as Figure 1 , 3 As shown in Figure 4, specifically, the guardrail assembly 7 includes a strip frame 701. A strip frame 701 is respectively provided above the two rows of railings 501. A positioning block 702 is fixedly installed on the top of each railing 501. Each positioning block 702 is movably installed inside the adjacent strip frame 701. Threaded grooves 703 are respectively opened at both ends of the top of each crossbar 401. Bolts 704 are threaded to both ends of each strip frame 701. The tail end of each bolt 704 is threaded to the inside of the adjacent threaded groove 703.
[0033] More specifically, if it is necessary to place the tubular material between each pair of adjacent railings 501, each bolt 704 can be rotated to rotate out of the corresponding threaded groove 703, so that the strip frame 701 can be removed from the top of the two sets of side railing assemblies 5 to facilitate unloading of the tubular material. If it is not necessary to lift the tubular material, the two strip frames 701 can be reinstalled and reset.
[0034] In summary: If it is necessary to lift the tubular material, first control the lifting mechanism 2 to lower the support plate 3 to its lowest position, then disassemble the two sets of guardrail assemblies 7 respectively, and then place the tubular material on top of the support plate 3, so that both ends of the tubular material pass through the two sets of side rail assemblies 5 respectively. Then control the two sets of pressing assemblies 6 to clamp and fix the tubular material with the two sets of side rail assemblies 5 respectively. Finally, control the lifting mechanism 2 to gradually move the support plate 3 upward to complete the lifting of the tubular material. When the support plate 3 rises to a suitable height, control the two sets of pressing assemblies 6 to release the fixation of the two sets of side rail assemblies 5 to the tubular material respectively. If it is not necessary to lift the tubular material, reinstall the two sets of guardrail assemblies 7 above the two sets of side rail assemblies 5, and other building materials required for construction can be placed on top of the support plate 3.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
