Description

Technical Field

[0001] This utility model belongs to the field of high-altitude hoisting technology, specifically, it relates to a high-altitude building material hoisting device. Background Technology

[0002] Lifting equipment is commonly used in building construction projects, especially in the construction of high-rise buildings. Various building materials, such as reinforcing bars, steel pipes, steel plates, and square tubes, need to be lifted to the construction site using tower cranes or similar equipment. However, existing lifting equipment often lacks an unloading platform for placing the materials on the hooks when lifting materials onto the floors of high-rise buildings. Therefore, the equipment can only lift the materials to the openings between the floor slabs on the outside of the construction floor, and then manually or with a hand-operated hoist, drag the hooks and materials into the building before finally releasing the steel ropes to unload the materials.

[0003] However, this unloading method requires construction workers to stand on the edge of the floor slab to drag and unload materials, which poses a risk of both workers and materials falling from a height, creating significant safety hazards. In addition, the operation is cumbersome, time-consuming, and labor-intensive. Furthermore, during the dragging process into the building, the steel ropes of the hoisting equipment may rub against the floor slab, walls, etc., which can not only damage the building but also easily cause wear and tear on the steel ropes. Utility Model Content

[0009] In one alternative embodiment, each of the two booms has a groove recessed outward on its opposite side;

[0010] The hanging plate includes a hanging plate body with an integrally formed structure and sliding parts. The sliding parts are located on both sides of the hanging plate body, and the two sliding parts are slidably disposed in the sliding groove. The end of each of the two sliding parts facing the baffle is respectively provided with a limiting part protruding from the hanging plate body.

[0011] The end of the hanging plate body facing the third pulley is provided with a clearance groove, and a connecting column is provided between the two side walls of the clearance groove. The hook passes through the clearance groove and is detachably hooked and connected to the connecting column. The end of the hanging plate body away from the clearance groove is inclined downward and recessed to form an installation groove, and the first pulley is fixedly installed in the installation groove.

[0012] In one alternative embodiment, a nylon guide groove is fixedly embedded in the chute, the cross-sectional shape of the nylon guide groove matching the cross-sectional shape of the chute, and the two sliding portions of the hanging plate are slidably disposed within the nylon guide groove.

[0013] In one alternative embodiment, the two booms are provided with limiting holes that penetrate the side walls of the booms and the nylon guide grooves. The limiting rod is inserted between the two booms through the two limiting holes. During the hoisting process, the end face of the hoisting plate facing the third pulley abuts against the limiting rod.

[0014] In one alternative embodiment, the limiting hole is an oblong hole structure extending along the length of the boom, and a nylon sleeve is embedded in the inner part of the limiting hole within the side wall range of the boom.

[0018] The beneficial effects of this utility model are:

[0019] This invention, by suspending two booms beyond the outer ends of the counterweight base, creates an unloading space between the boom ends and the outer ends of the counterweight base. By using a first winch and a second winch to vertically hoist and horizontally drag the material attached to the hooks, this invention automatically and stably places the building materials onto the floor slabs of high-rise buildings within the unloading space during the hoisting process. Once the materials are in place, construction workers are no longer required to stand on the floor edges to drag and unload them, thus eliminating the risk of workers or materials falling from heights. The lifting process is simple, time-saving, and labor-saving, avoiding the wear and damage to the building caused by friction between the steel rope and the floor slab or wall during the lifting operation. By setting a retractable limit rod 15 between the two booms 3, the limit rod 15 limits the lifting plate 5 during the vertical lifting of the material, so that the lifting plate 5 will not slide along the boom 3 during the vertical lifting of the material, so as to ensure that the steel rope of the hook 12 and the first winch 7 is always in a fixed horizontal position during the vertical lifting of the material, thereby ensuring the stable lifting of the material.

[0032] When existing hoisting equipment is used to hoist building materials onto the floors of high-rise buildings, construction workers need to stand on the edge of the floor to drag and unload the materials. This poses a significant safety hazard, as both the workers and the unloaded materials are at risk of falling from a height. The process is also cumbersome, time-consuming, and labor-intensive. Furthermore, there are concerns that the steel cables may damage the building or cause wear and tear.

[0033] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.

[0034] In one implementation, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A high-altitude building material hoisting device is provided, including a counterweight base 1, a column 2, a boom 3, a diagonal brace 4, a hanging plate 5, a baffle 6, a first winch 7, a second winch 8, a first pulley 9, a second pulley 10, a third pulley 11, and a limiting rod 15; wherein, the column 2 is fixedly installed on the counterweight base 1, and two booms 3 are fixedly installed at an angle downward on one side of the upper end of the column 2, with the two booms 3 extending beyond the outer end of the counterweight base 1, and a diagonal brace 4 is installed between the lower end of the two booms 3 and the column 2, and a hanging plate 5 that can slide along the length direction of the boom 3 is provided between the two booms 3, and a limiting rod 15 for preventing the hanging plate 5 from sliding upward during hoisting is movably inserted between the two booms 3, and a baffle 6 for limiting the hanging plate 5 is also fixedly installed between the lower ends of the two booms 3;

[0035] A first pulley 9 is fixedly installed on the hanging plate 5, a second pulley 10 is fixedly installed on the top of the column 2, a first winch 7 is installed on the counterweight base 1, the end of the steel rope of the first winch 7 is connected to a hook 12 and passes around the second pulley 10 and the first pulley 9 in sequence and is suspended in the air; a third pulley 11 is fixedly installed on the top of the column 2 at the position between the two booms 3, a second winch 8 is installed on the counterweight base 1, the end of the steel rope of the second winch 8 is connected to a hook 13 and passes around the third pulley 11 and is hooked to the hanging plate 5.

[0036] Before the hoisting begins, the hoisting device is placed on the floor slab of the construction floor. The second winch 8 lowers the hoisting plate 5 to the lower end of the two booms 3, and the limit rod 15 is inserted between the two booms 3. Then, the hoisting device is pushed outward until the two booms 3 are in a position that extends out of the floor slab for easy material hoisting, and the counterweight base 1 is fixed. Then, the first winch 7 lowers the hook 12 to hang building materials and other materials. Thus, by setting a retractable limiting rod 15 between the two booms 3, during the lowering of the hook 12, the lifting plate 5 is pushed upward to a position where it abuts against the limiting rod 15 under the action of the steel rope of the hook 12 and the first winch 7, so that the limiting rod 15 limits the lifting plate 5, thereby preventing the lifting plate 5 from sliding along the boom 3 during the vertical lifting of materials, so as to ensure that the steel rope of the hook 12 and the first winch 7 is always in a fixed horizontal position during the vertical lifting of materials, thereby ensuring the stable lifting of materials.

[0037] During the hoisting process, a first winch 7 is set up to hang building materials and other materials via a hook 12 connected to the steel rope of the first winch 7. The materials are supported by a hanging plate 5 set between the two booms 3, and the steel rope of the first winch 7 is guided by a first pulley 9 and a second pulley 10. Thus, the materials hanging on the hook 12 are vertically hoisted by the winding and unwinding action of the steel rope of the first winch 7. After the materials are vertically hoisted into place, a second winch 8 is set up to drag the hanging plate 5 via a hook 13 connected to the steel rope of the second winch 8. The steel rope of the second winch 8 is guided by a third pulley 11. Thus, the hanging plate 5 is dragged upward along the length of the boom 3 by the winding and unwinding action of the steel rope of the second winch 8, thereby achieving the horizontal dragging of the materials hanging on the hook 12. Thus, by suspending the two booms 3 beyond the outer ends of the counterweight base 1, a material unloading space can be formed in the horizontal space between the ends of the booms 3 and the outer ends of the counterweight base 1, which can be used to unload materials on the hooks 12. After the building materials and other materials are vertically hoisted into place, the hoisting device can be pushed into the floor to a position where the limit rod 15 can be safely pulled out, and the second winch 8 can be started to horizontally drag the materials to unload them onto the unloading space located at the outer end of the counterweight base 1 on the floor. It is not necessary to push the hoisting device into the floor until the materials are completely inside the floor area. In this way, construction personnel do not need to stand on the edge of the floor to drag and unload materials, avoiding the safety hazards caused by manual unloading, and avoiding damage to the building and wear on the steel ropes caused by friction between the steel ropes and the floor and walls during unloading.

[0038] Therefore, during the process of hoisting building materials onto the floor slabs of high-rise buildings, the limiting rod 15 can limit the hoisting plate 5 to prevent it from sliding along the boom 3 during the vertical hoisting of materials, thus ensuring stable hoisting of materials. The first winch 7 and the second winch 8 can be used to vertically hoist and horizontally drag the materials hanging on the hook 12, thereby automatically hoisting building materials and other materials to the unloading space above the floor slab between the end of the boom 3 and the outer end of the counterweight base 1. Then, the steel rope can be released by the first winch 7 to place the materials stably on the floor slab at the unloading space. In this way, after the materials are hoisted into place, construction workers do not need to stand on the edge of the floor to drag and unload the materials, thus eliminating the safety hazard of construction workers and unloaded materials falling from heights. The hoisting process is simple to operate, saving time and effort. Moreover, this hoisting device only needs to be installed on the floor slab of the construction floor, so that the steel rope will not rub against the floor slab, walls, etc. during the hoisting process, thereby avoiding damage to the building caused by hoisting operations. At the same time, it avoids wear caused by friction between the steel rope and the floor slab, walls, etc., which can effectively improve the load-bearing capacity of the steel rope and extend its service life.

[0039] In some implementations, please refer to Figure 1 , Figure 2 , Figure 4 Each of the two booms 3 has a groove 301 recessed outward on one side. The lifting plate 5 includes a lifting plate body 501 with an integral structure and a sliding part 502. The sliding parts 502 are located on both sides of the lifting plate body 501, and the two sliding parts 502 are slidably arranged in the groove 301. In this way, the sliding parts 502 are supported and limited by the groove 301 of the two booms 3 to form a stable support for the lifting plate 5, thereby ensuring the load-bearing capacity of the lifting plate 5 during the lifting process and ensuring that the lifting device can complete the conventional building material lifting operation.

[0040] In this embodiment, each of the two sliding parts 502 has a limiting part 503 protruding from the lifting plate body 501 at one end facing the baffle 6. In this way, the two limiting parts 503 can effectively limit the position of the lifting plate 5 at the lower end of the two booms 3, thereby allowing the lifting plate 5 to have space between the lifting plate body 501 and the baffle 6 to facilitate the normal winding and unwinding of the steel rope of the first winch 7, avoiding the steel rope from being clamped by the lifting plate body 501 and the baffle 6 and getting stuck, thus ensuring the orderly progress of the building material hoisting operation.

[0041] In this embodiment, the end of the lifting plate body 501 facing the third pulley 11 is provided with a relief groove 504, and a connecting column 505 is provided between the two side walls of the relief groove 504. The hook 13 passes through the relief groove 504 and is detachably hooked and connected to the connecting column 505. In this way, on the one hand, it is convenient to install and detach the hook 13, and on the other hand, it can effectively improve the structural strength of the connection between the hook 13 and the lifting plate 5, thereby effectively ensuring the reliability of the second winch 8 dragging the lifting plate 5 through the hook 13, and further effectively ensuring the stability and reliability of the second winch 8 horizontally dragging and lifting materials, so as to avoid the safety accident of the hook 13 slipping off the lifting plate 5.

[0042] The end of the lifting plate body 501 facing away from the avoidance groove 504 is inclined downward and recessed, forming an installation groove 506. The first pulley 9 is fixedly installed in the installation groove 506. Thus, by installing the first pulley 9 through the inclined downward recessed installation groove 506, the first pulley 9 can be in a state where the inclination angle is greater than the inclination angle of the two booms 3 and the lifting plate 5. This allows the steel rope mounted on the first pulley 9 to have a certain gap with the lifting plate body 501 during the hoisting process, thereby avoiding interference from the lifting plate body 501 of the lifting plate 5 on the hoisting state of the steel rope of the first winch 7. This effectively ensures the stability and reliability of the first winch 7 in vertically hoisting materials.

[0043] In this embodiment, the lifting plate 5 is integrally formed, and the integral forming process can be such as casting or CNC milling. In this way, the structural strength of the lifting plate 5 can be effectively guaranteed, thereby effectively improving the load-bearing capacity of the lifting plate 5, and thus effectively guaranteeing the lifting capacity of this lifting device.

[0044] In this embodiment, two booms 3 are fixedly installed at the upper end of one side of the column 2 at an angle downwards. Correspondingly, the sliding grooves 301 on the two booms 3 are arranged at an angle downwards. Thus, in a single lifting operation, after the first winch 7 and the second winch 8 vertically lift and horizontally drag the material hanging on the hook 12, the lifting plate 5 is located at the upper position of the boom 3. Subsequently, after unloading, the lifting plate 5 slides downwards along the sliding groove 301 under the weight of the hook 12 and its own weight. The steel cables of the first winch 7 and the second winch 8 are released synchronously, allowing the lifting plate 5 to slide back to the lower position of the two booms 3. Then, the lifting plate 5 is fixed, and the first winch 7 continues to release the hook 12 to fall for the next lifting operation. In addition, the spaced arrangement of the two booms 3 provides good operating space for the steel cable of the second winch 8.

[0045] In some implementations, please refer to Figure 1 , Figure 4 A nylon guide groove 14 is fixedly embedded in the chute 301. The cross-sectional shape of the nylon guide groove 14 matches the cross-sectional shape of the chute 301. The two sliding parts 502 of the hanging plate 5 are slidably disposed in the nylon guide groove 14. In this way, by setting the nylon guide groove 14 between the two sliding parts 502 of the hanging plate 5 and the chute 301 of the two booms 3, the frictional resistance of the hanging plate 5 during the process of the second winch 8 dragging the hanging plate 5 can be effectively reduced, thereby effectively reducing the difficulty of the second winch 8 dragging the hanging plate 5; at the same time, it can also facilitate the quick sliding of the hanging plate 5 down to the lower end of the two booms 3 for the next hoisting after unloading.

[0046] In some implementations, please refer to Figures 1-4 Each of the two booms 3 has a limiting hole 302 that passes through the side wall of the boom 3 and the nylon guide groove 14. The limiting rod 15 passes through the two limiting holes 302 and is removably inserted between the two booms 3. During the hoisting process, the end face of the lifting plate 5 facing the third pulley 11 abuts against the limiting rod 15. In this way, by opening limiting holes 302 on the two booms 3 for inserting the limiting rod 15, the limiting holes 302 can limit the limiting rod 15 during the vertical hoisting of the material, and the limiting rod 15 can limit the lifting plate 5. This prevents the lifting plate 5 from sliding along the boom 3 during the vertical hoisting of the material, thus ensuring that the steel rope of the hook 12 and the first winch 7 remains in a fixed horizontal position during the vertical hoisting of the material, thereby ensuring the stable hoisting of the material.

[0047] In practical applications, after the limiting rod 15 is inserted into the two booms 3, pins can be inserted at one or both ends of the limiting rod 15 at positions outside the two booms 3. The pins can limit the limiting rod 15, preventing it from falling out of the limiting hole 302 during vertical hoisting, thus effectively ensuring the stable limiting of the limiting rod 15 on the lifting plate 5.

[0048] In this embodiment, the limiting hole 302 is an oblong hole structure extending along the length of the boom 3. This allows the limiting rod 15 to have room to move after the material has been vertically hoisted into place, preventing it from being compressed and difficult to remove. Furthermore, a nylon sleeve 16 is embedded on the inner side of the limiting hole 302 within the side wall area of ​​the boom 3. By placing the nylon sleeve 16 on the inner wall of the limiting hole 302, the limiting rod 15 contacts the nylon sleeve 16, ensuring reliable limiting of the lifting plate 5 while effectively reducing frictional resistance during removal. This facilitates convenient and efficient removal of the limiting rod 15 after the material has been vertically hoisted into place.

[0049] In some implementations, please refer to Figure 1 , Figure 2 , Figure 3 The first winch 7 is fixedly installed on the side of the counterweight base 1 away from the boom 3, and the steel cable of the first winch 7 is set across the column 2. In this way, on the one hand, the weight of the counterweight base 1 can be further increased by the first winch 7 to ensure the stability and load-bearing capacity of this lifting device; on the other hand, during the lifting process, the steel cable of the first winch 7 can apply downward pressure to the column 2 through the second pulley 10, thereby improving the stability of the column 2 and the counterweight base 1.

[0050] In some implementations, please refer to Figure 1 , Figure 2 , Figure 3 The second winch 8 is fixedly installed on the side of the counterweight base 1 near the boom 3, and the steel cable of the second winch 8 is set on the side of the column 2 near the boom 3. In this way, on the one hand, the weight of the counterweight base 1 can be further increased by the second winch 8 to ensure the stability and load-bearing capacity of this lifting device; on the other hand, during the process of the second winch 8 dragging the suspended plate 5, interference between the steel cable of the second winch 8 and the column 2 can be effectively avoided, thereby ensuring the smoothness of the second winch 8 dragging the suspended plate 5.

[0051] In some implementations, please refer to Figure 1 , Figure 2 , Figure 3The portion of the steel rope of the first winch 7 located above the boom 3 is parallel to the length direction of the boom 3, and the portion of the steel rope of the second winch 8 located between the two booms 3 is also parallel to the length direction of the boom 3. This effectively ensures the uniformity of force on the lifting plate 5 during the vertical lifting and horizontal dragging of materials suspended on the hook 12 by the first winch 7 and the second winch 8, respectively. It also ensures that the traction force of the steel rope from the second winch 8 on the lifting plate 5 is parallel to the sliding direction of the lifting plate 5, thereby effectively reducing the dragging resistance of the second winch 8, saving work on the second winch 8, and facilitating faster and more stable horizontal dragging of materials by the second winch 8.

[0052] In practical applications, according to actual needs, rollers with locking functions can be installed at the bottom of the counterweight base 1. This allows for time-saving and labor-saving handling and pushing of the hoisting device when it needs to be moved and pushed, and the rollers can be locked during hoisting to stabilize the hoisting device. In practical applications, the column 2 in the hoisting device, or the connection between the column 2 and the counterweight base 1, can adopt an assembly structure that can be bolted together to achieve detachable installation between the column 2 and the counterweight base 1. This allows for easy transfer and transportation of the hoisting device by disassembling and separating the column 2 and the counterweight base 1, and can also effectively shorten the overall height of the hoisting device, so that it can be transferred to the construction floor of a high-rise building by elevator. Correspondingly, the gap between the third pulley 11 and the column 2 should be greater than the width of the hook 13 at the end of the steel rope connected to the second winch 8, so that the steel ropes of the first winch 7 and the second winch 8 can be fully recovered during disassembly and transportation, thereby avoiding interference with the transportation operation.

[0053] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
