Technical Field
[0001] This utility model relates to the field of building construction technology, and in particular to a building construction lifting device. Background Technology
[0002] Construction is a production activity carried out by people using various building materials and machinery according to specific design blueprints within a certain space and time to build various building products. Various materials are often used in the construction process, and sometimes lifting devices are needed to lift the materials to the required height.
[0003] Existing technologies, such as Chinese Patent Publication No. CN213505772U, disclose a material lifting device for construction, including a base. Support mechanisms are fixedly connected to the upper left and upper right sides of the base, and guide rails are fixedly connected to the front center of each of the two support mechanisms. Two sets of sliders are slidably connected to the lower front of each guide rail, and a material feeding device is fixedly connected to the front of all four sets of sliders. A connecting plate is fixedly connected to the upper end of the support mechanisms, and a through slot is formed in the upper center of the connecting plate. A support block and a connecting block are fixedly connected to the rear center and upper front of the connecting plate, respectively. A driving device is fixedly connected to the upper center of the support block, and the upper front of the driving device is movably inserted into the rear center of the connecting block. This utility model's material lifting device for construction, by setting a driving device, allows a motor to steadily drive a synchronous belt to rotate, and the fixed block to steadily lift the material upwards, reducing the risk of material falling. However, the limiting block set in this utility model means that the equipment can only stably lift objects of a fixed volume. It cannot fix longer materials commonly used in construction. Furthermore, after lifting, the equipment will be top-heavy and bottom-light, which may cause the equipment to tip over.
[0004] To address the issue that construction lifting devices cannot secure materials of different shapes and sizes, materials are often limited and secured during lifting to ensure safety. However, construction materials come in various shapes and sizes, and existing equipment can only secure materials of specific shapes and sizes. Furthermore, the equipment is prone to tipping over due to top-heavy lifting. Therefore, improvements are needed. Utility Model Content

One end of the compression spring is fixedly connected to the surface of the movable plate, and the other end of the compression spring is fixedly connected to the surface of the clamping plate.
[0007] Furthermore, the number of the dual-axis motor, winding wheel, steel cable, pulley, T-slot, T-block, movable plate, telescopic rod, clamping plate, and compression spring are all in two sets and arranged symmetrically, with each set containing two winding wheels, steel cables, pulleys, telescopic rods, and compression springs.

[0009] Furthermore, the number of the rotating shaft, the clamping plate, and the torsion spring are two sets and arranged symmetrically. The surface of the clamping plate is provided with anti-slip texture, and the end of the T-block away from the lifting plate is fixedly connected to a handle.
[0010] Furthermore, the surface of the base is provided with a stabilizing device, the stabilizing device including a placement groove, a fixing frame slidably connected to the surface of the placement groove, an inclined groove opened on the surface of the fixing frame, a sliding groove opened on the surface of the fixing frame, a compression spring two fixedly connected to the surface of the sliding groove, and an inclined plate fixedly connected to the other end of the compression spring two, the inclined plate cooperating with the inclined groove.
[0011] Furthermore, an auxiliary shaft is fixedly connected to the surface of the placement groove, an auxiliary plate is rotatably connected to the surface of the auxiliary shaft, an auxiliary groove is formed on the surface of the auxiliary plate, an auxiliary block is fixedly connected to the surface of the fixing frame, the auxiliary block is slidably connected to the surface of the auxiliary groove, and a groove is formed on the surface of the inclined plate.
[0012] Furthermore, the number of the placement groove, fixing frame, inclined groove, sliding groove, compression spring II, inclined plate, auxiliary shaft, auxiliary plate, auxiliary groove, auxiliary block and groove are all in two sets and are arranged symmetrically, and the number of the sliding groove, compression spring II, auxiliary shaft, auxiliary plate, auxiliary groove and auxiliary block in each set is two.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting an adjustment device, when the material size is small, the material can be directly placed on the lifting plate, and the position of the clamping plate can be adjusted by using the telescopic rod and compression spring, so that materials of different sizes can be stably clamped. When the material size is large, the handle can be held and the T-block can be pulled to slide out along the T-slot, thereby moving the two sets of movable plates away from each other and increasing the distance between the two sets of clamping plates, thus accommodating larger materials. In order to prevent the material from sliding and causing the T-plate to move arbitrarily, a locking tooth and a locking plate are set. Before pulling the T-block, the locking plate needs to be pulled first to rotate it outward along the rotating axis and tighten the torsion spring. After the locking plate is released, the T-block is pulled to the appropriate position. Under the rebound action of the torsion spring, the locking plate will engage with the locking tooth, restricting the T-block from sliding outward. After clamping, the dual-axis motor is started, and the lifting plate is lifted by steel cable. By setting an adjustment device, materials of different sizes and shapes can be stably clamped, avoiding material shaking or even falling during the lifting process, which may cause safety accidents. This effectively improves the applicability of the equipment.
[0014] 2. In this utility model, by setting a stabilizing device, the auxiliary plate is rotated to make it rotate outward along the auxiliary axis of the placement slot. The fixed frame is pulled by holding the groove on the inclined plate, making it slide outward along the placement slot. After sliding out of the placement slot, the auxiliary block on the fixed frame will slide along the auxiliary slot. When the inclined plate slides out of the placement slot completely, the compression spring two, which has been in a compressed state, rebounds, making the inclined plate slide down along the slide until it contacts the ground. This can lower the center of gravity of the equipment by using the fixed frames and inclined plates that unfold on both sides, avoiding the top-heavy state that could cause the equipment to tip over. It can also make it easy to place materials onto the lifting plate using the inclined plate and the inclined slot. When the lifting is complete and the equipment needs to be moved, the groove is held and the inclined plate is pushed upward along the slide, which compresses the compression spring two. After the inclined plate returns to its original position, the fixed frame is pushed inward, making it slide into the placement slot. Then the auxiliary plate is rotated to put it back into the placement slot. By setting a stabilizing device, the center of gravity of the equipment can be lowered to avoid the top-heavy state that could cause the equipment to tip over, and it can also make it easy to place materials onto the lifting plate, thus effectively improving the safety of the equipment.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a building construction lifting device, including a base 1, a self-locking universal wheel 2, a support frame 3 and an adjustment device 4. The self-locking universal wheel 2 is fixedly connected to the bottom surface of the base 1, the support frame 3 is fixedly connected to the top surface of the base 1, and the adjustment device 4 is disposed on the surface of the base 1.
[0018] The specific settings and functions of the adjustment device 4 and the stabilizing device 5 will be explained in detail below.
[0019] In this embodiment: the adjusting device 4 includes a dual-axis motor 401, which is fixedly mounted on the surface of the base 1. The output end of the dual-axis motor 401 is fixedly connected to a winding wheel 402. A steel cable 403 is provided on the surface of the winding wheel 402. A pulley 404 is fixedly connected to the surface of the support frame 3. The steel cable 403 is slidably connected to the surface of the pulley 404. One end of the steel cable 403 passes over the pulley 404 and is fixedly connected to a lifting plate 405. A T-slot 406 is provided on the surface of the lifting plate 405. A T-block 407 is slidably connected to the surface of the T-slot 406. A movable plate 408 is fixedly connected to the surface of the T-block 407. A telescopic rod 409 is fixedly connected to the surface of the movable plate 408. A clamping plate 410 is fixedly connected to the other end of the telescopic rod 409. A compression spring 411 is sleeved and connected to the surface of the telescopic rod 409. One end of the compression spring 411 is fixedly connected to the surface of the movable plate 408, and the other end of the compression spring 411 is fixedly connected to the surface of the clamping plate 410.
[0020] The effect achieved by the above components is as follows: starting the dual-axis motor 401 causes the steel cable 403 on the winding wheel 402 to slide along the pulley 404 and raise or lower the lifting plate 405. The lifting plate 405 is set to facilitate the placement of materials. The telescopic rod 409 and the compression spring 411 enable the clamping plate 410 to adapt to materials of different shapes and sizes. When the material size is large, the T-block 407 can slide along the T-slot 406 away from the lifting plate 405, thereby causing the two sets of movable plates 408 to move away from each other, thus increasing the usable distance between the two sets of clamping plates 410.
[0021] Specifically, the dual-axis motor 401, winding wheel 402, steel cable 403, pulley 404, T-slot 406, T-block 407, movable plate 408, telescopic rod 409, clamping plate 410, and compression spring 411 are all in two sets and symmetrically arranged, with each set containing two winding wheels 402, steel cable 403, pulley 404, telescopic rod 409, and compression spring 411.
[0022] The aforementioned components achieve the following effects: four steel cables 403 are provided to allow the lifting plate 405 to move up and down more stably. Two telescopic rods 409 and two compression springs 411 are provided for each set to ensure a more secure clamping.
[0023] Specifically, the T-block 407 has a locking tooth 412 on the side of its surface away from the movable plate 408. A rotating shaft 413 is fixedly connected to the surface of the lifting plate 405. A locking plate 414 is rotatably connected to the surface of the rotating shaft 413. The locking plate 414 is locked to the surface of the locking tooth 412. A torsion spring 415 is sleeved and connected to the surface of the rotating shaft 413. One end of the torsion spring 415 is fixedly connected to the surface of the locking plate 414, and the other end of the torsion spring 415 is fixedly connected to the surface of the lifting plate 405.
[0024] The effect achieved by the above components is as follows: the rebound action of the torsion spring 415 makes the clamping plate 414 engage with the clamping teeth 412, preventing the T-block 407 from moving arbitrarily during clamping. The rotating shaft 413 is provided to facilitate the rotation of the clamping plate 414.
[0025] Specifically, there are two sets of rotating shaft 413, clamping plate 414 and torsion spring 415 arranged symmetrically. The surface of clamping plate 410 is provided with anti-slip texture 416. A handle 417 is fixedly connected to the end of T-block 407 away from lifting plate 405.
[0026] The effects achieved by the above components are as follows: the anti-slip texture 416 is set to increase the friction between the clamping plate 410 and the material, making the clamping more stable; the handle 417 is set to facilitate the pulling of the T-block 407.
[0027] Specifically, a stabilizing device 5 is provided on the surface of the base 1. The stabilizing device 5 includes a placement groove 501. A fixing frame 502 is slidably connected to the surface of the placement groove 501. An inclined groove 503 is opened on the surface of the fixing frame 502. A sliding groove 504 is opened on the surface of the fixing frame 502. A compression spring 505 is fixedly connected to the surface of the sliding groove 504. An inclined plate 506 is fixedly connected to the other end of the compression spring 505. The inclined plate 506 cooperates with the inclined groove 503.
[0028] The effects achieved by the above components are as follows: the inclined groove 503 and the inclined plate 506 facilitate the placement of materials on the lifting plate 405; the sliding groove 504 and the second compression spring 505 are provided so that when the inclined plate 506 slides out of the placement groove 501, it will be pushed down along the sliding groove 504 until it contacts the ground under the rebound action of the second compression spring 505.
[0029] Specifically, an auxiliary shaft 507 is fixedly connected to the surface of the placement groove 501, an auxiliary plate 508 is rotatably connected to the surface of the auxiliary shaft 507, an auxiliary groove 509 is formed on the surface of the auxiliary plate 508, an auxiliary block 510 is fixedly connected to the surface of the fixing frame 502, the auxiliary block 510 is slidably connected to the surface of the auxiliary groove 509, and a groove 511 is formed on the surface of the inclined plate 506.
[0030] The effects achieved by the above components are as follows: the auxiliary plate 508 and the auxiliary groove 509 are provided to facilitate the sliding of the auxiliary block 510 in the auxiliary groove 509 after the fixed frame 502 slides out of the placement groove 501, so as to prevent the fixed frame 502 from detaching from the entire equipment; the auxiliary shaft 507 is provided to facilitate the insertion of the auxiliary plate 508 into the placement groove 501; and the groove 511 is provided to facilitate the pulling or pushing of the inclined plate 506 and the fixed frame 502.
[0031] Specifically, the number of placement slots 501, fixing brackets 502, inclined slots 503, sliding slots 504, compression springs 505, inclined plates 506, auxiliary shafts 507, auxiliary plates 508, auxiliary slots 509, auxiliary blocks 510, and grooves 511 are all in two sets and are arranged symmetrically. Each set contains two sliding slots 504, compression springs 505, auxiliary shafts 507, auxiliary plates 508, auxiliary slots 509, and auxiliary blocks 510.
[0032] The effects achieved by the above components are as follows: the two sets of fixed frames 502 are set to ensure the left and right balance of the equipment, and the two sets of inclined plates 506 and inclined grooves 503 are set to facilitate the placement of materials on the lifting plate 405 from both sides.
[0033] Working principle: By setting the adjustment device 4, when the material size is small, the material is placed directly on the lifting plate 405. The position of the clamping plate 410 is adjusted by the telescopic rod 409 and the compression spring 411, so that materials of different sizes can be stably clamped. When the material size is large, the handle 417 can be held to pull the T-block 407, so that it slides out along the T-slot 406, thereby making the two sets of movable plates 408 move away from each other, increasing the distance between the two sets of clamping plates 410, thus accommodating larger materials. In order to prevent the T-plate from moving randomly due to material slippage, the locking teeth 412 and the locking plate 414 are set. Before moving the T-block 407, the clamping plate 414 needs to be pulled to rotate it outward along the rotating shaft 413 and the torsion spring 415 tightened. After the clamping plate 414 is released from its restraint, the T-block 407 is pulled to the appropriate position. Under the rebound action of the torsion spring 415, the clamping plate 414 will engage with the clamping teeth 412, restricting the T-block 407 from sliding outward. After clamping is completed, the dual-axis motor 401 is started, and the lifting plate 405 is lifted using the steel cable 403. By setting the adjustment device 4, materials of different sizes and shapes can be stably clamped, avoiding material shaking or even falling during the lifting process, which could lead to safety accidents. This effectively improves the applicability of the equipment. Furthermore, by setting a stabilizing device 5, the auxiliary plate 508 is rotated to rotate outward along the auxiliary shaft 507 towards the placement groove 501. The fixed frame 502 is pulled by holding the groove 511 on the inclined plate 506, causing it to slide outward along the placement groove 501. After sliding out of the placement groove 501, the auxiliary block 510 on the fixed frame 502 slides along the auxiliary groove 509. When the inclined plate 506 has completely slid out of the placement groove 501, the compression spring 505, which has been in a compressed state, rebounds, causing the inclined plate 506 to slide downward along the sliding groove 504 until it contacts the ground. This lowers the center of gravity of the equipment through the fixed frames 502 and inclined plates 506 that unfold on both sides, preventing head injuries. The top-heavy design prevents the equipment from tipping over. However, the inclined plate 506 and inclined groove 503 facilitate the placement of materials onto the lifting plate 405. When the lifting is complete and the equipment needs to be moved, hold the groove 511 and push the inclined plate 506 upward along the sliding groove 504 to compress the compression spring 505. After the inclined plate 506 returns to its original position, push the fixing frame 502 inward to slide it into the placement groove 501. Then, rotate the auxiliary plate 508 to retract it into the placement groove 501. By setting the stabilizing device 5, the center of gravity of the equipment can be lowered to avoid tipping over due to the top-heavy design, and it is also convenient to place materials onto the lifting plate 405, thus effectively improving the safety of the equipment.
