Description

Technical Field

[0001] This invention relates to the field of hoisting devices, and more specifically, to a highly stable hoisting device for building renovation and its operation method. Background Technology

[0002] Prefabricated steel structures are building structures made of steel materials, mainly including steel profiles, steel plates, steel columns, and steel trusses. Due to their advantages of light weight, convenient construction, and reusability, they are widely used in large-area buildings such as large factories and stadiums. During the splicing process of prefabricated steel structures, because the steel plates have the greatest self-weight, they often need to be hoisted with ropes and then fixed by welding or bolts.

[0003] A search revealed that Chinese patent CN118206001A, published in the prior art, discloses a "lifting device for assembling building steel structures," which includes a support base. Two bidirectional lead screws are symmetrically rotatably connected to the inner wall of the support base, and two connecting blocks are connected to the outer wall of the bidirectional lead screws via a screw-nut pair. This invention provides a lifting device for assembling building steel structures. By pushing two side plates, the steel plate is positioned at the center of the support base, achieving optimal stability during steel plate lifting. Tightening the four lifting ropes causes the positioning blocks to press against the top of the steel plate, fixing it securely to the support base. This not only improves safety but also prevents movement on the support base, enhancing overall stability during lifting. Furthermore, by adjusting the position of the sleeve, multiple layers of stacked steel plates can be fixed together. When the steel plate sways laterally due to improper operation, the damper can swing in the opposite direction of the lateral sway, counteracting the inertia and reducing swaying. However, the following drawbacks still exist:

[0004] (1) The top of the existing hoisting device used for building renovation is connected by multiple soft ropes. When it is necessary to hoist building components, the direction needs to be adjusted. The soft ropes will have inertia after rotation, causing the hoisted building components to swing back and forth, which cannot guarantee the stability of hoisting adjustment.

[0005] (2) The existing hoisting device used for building renovation is fixed by the edge lateral clamping device. However, the lower side of the hoisting device does not have a structure for positioning the accessories. If the lateral clamping is unstable during the hoisting process, the accessories will fall downward under their own weight, affecting the stability of the hoisting device.

[0006] Therefore, we have made improvements to this by proposing a highly stable hoisting device for building renovation and its operation method. Summary of the Invention

[0007] The purpose of this invention is to address the problem that existing hoisting devices used in building renovations rely on multiple flexible ropes connected at the top. When hoisting building components, the direction needs to be adjusted, but the flexible ropes have inertia after rotation, causing the hoisted building components to swing back and forth, which cannot guarantee the stability of the hoisting adjustment. Furthermore, existing hoisting devices used in building renovations achieve fixation through edge lateral clamping devices, but the lower side of the hoisting device does not have a structure for positioning the components. If there is instability in the lateral clamping during the hoisting process, the components will fall downwards under their own weight.

[0008] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0009] A highly stable hoisting device for building renovation and its operation method are disclosed to improve the above-mentioned problems.

[0010] The present invention is as follows:

[0011] The device includes a base, on which a vertical pole is fixedly mounted. A top plate is rotatably mounted on the top of the vertical pole. A directional adjustment component is provided on the lower side of the top plate away from the vertical pole. A crossbeam is installed at the lower end of the directional adjustment component. Electric adjustment plates are telescopically provided at both ends of the crossbeam. A fixing plate is fixedly mounted at the lower end of the electric adjustment plate. A clamping component is provided on the side wall of the fixing plate. A base support component is provided at the lower end of the fixing plate.

[0012] As a preferred embodiment of the present invention, the steering assembly includes a vertical rod installed at the lower end of the top plate, and an electric rotating rod is rotatably provided on the lower side of the vertical rod.

[0013] As a preferred technical solution of the present invention, an outer plate is installed on the outer wall of the plumb rod, and a sliding groove is opened on the lower side of the outer plate. An abutting roller is provided at the end of the sliding groove away from the plumb rod, and a first motor is connected to the upper end of the abutting roller.

[0014] As a preferred technical solution of the present invention, a sliding plate is slidably provided inside the slide groove near one end of the vertical rod, side grooves are provided on the front and rear sides of the slide groove, spring plates that cooperate with the side grooves are provided on the front and rear sides of the sliding plate, and a retaining ring that cooperates with the electric rotating rod is fixedly installed at the lower end of the sliding plate.

[0015] As a preferred technical solution of the present invention, the clamping assembly includes a connecting frame mounted on the surface of the fixing plate near the upright, a central groove is provided in the center of the connecting frame, a first conical roller is provided on the upper inner wall of the central groove, a second motor is connected to the upper end of the conical roller, and second conical rollers that cooperate with the first conical roller are provided on the inner walls of both sides of the central groove.

[0016] As a preferred technical solution of the present invention, the two ends of the central groove are provided with grooves, and a screw is rotatably provided inside the groove. A plate is fitted on the outer wall of the screw, and a clamp is installed on the outer wall of the plate.

[0017] As a preferred embodiment of the present invention, the side wall of the groove is provided with a side groove, and the side wall of the panel is provided with a side plate that cooperates with the side groove.

[0018] As a preferred technical solution of the present invention, the base support assembly includes a telescopic groove opened inside the lower side of the fixed plate, a telescopic plate slidably disposed inside the telescopic groove, and a support plate being installed on the lower outer wall of the telescopic plate.

[0019] As a preferred technical solution of the present invention, an electric toothed roller is rotatably installed inside the telescopic groove on the side away from the upright, and a slot is opened on the side of the telescopic plate near the electric toothed roller. A toothed plate that cooperates with the electric toothed roller is provided inside the slot. Limiting grooves are opened on the front and rear sides of the telescopic groove, and limiting plates that cooperate with the limiting grooves are provided on the front and rear sides of the telescopic plate.

[0020] A method for operating a high-stability hoisting device for building renovation includes the following steps:

[0021] Step 1: When it is necessary to adjust the hoisting direction of the modified building components, control the first motor to drive the elliptical contact roller to rotate, so that its short diameter end is close to the slide plate. The springs on the side walls of the front and rear spring plates contract, causing the slide plate to slide away from the electric rotating rod. This will cause the retaining ring to disengage from the surface of the electric rotating rod, and the rotation of the electric rotating rod can be controlled to adjust the hoisting direction of the building components.

[0022] Step 2: After adjustment, control the first motor to make the long diameter end of the contact roller close to the slide plate. Then push the slide plate to the left, causing the spring plate to slide in the side groove and stretch the spring so that it can retract. At the same time, it drives the retaining ring to slide towards the electric rotating rod. The retaining ring is locked by the grooves on its surface into the grooves on the surface of the electric rotating rod.

[0023] Step 3: When it is necessary to hoist building components of different thicknesses and sizes, control the second motor to drive the first conical roller connected to it to rotate, and engage to drive the second conical rollers on both sides to rotate.

[0024] Step 4: Drive the screw connected to it to rotate, engage and drive the panel to slide in the groove. With the side panel embedded in the side groove, the front and rear clamping plates can be adjusted to stably and firmly clamp building accessories of different thicknesses and sizes.

[0025] Step 5: After the building components are clamped and fixed at the front and rear, control the electric toothed roller to rotate so that it meshes with the toothed plate. With the limiting plate embedded in the limiting groove, it drives the lower end of the support plate to be adjusted up and down stably, so that the support plate abuts against the lower end surface of the building components, effectively supporting the lower side of the building components.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] In the solution of this invention:

[0028] 1. The system utilizes an electric rotating rod, abutment roller, sliding plate, side plates, and retaining ring. When adjusting the lifting direction of the modified building components, the first motor is controlled to rotate the elliptical abutment roller, bringing its short-diameter end closer to the sliding plate. The springs on the front and rear side spring plates contract, causing the sliding plate to slide away from the electric rotating rod. This allows the retaining ring to disengage from the electric rotating rod surface, enabling the electric rotating rod to rotate and adjust the lifting direction. After adjustment, the first motor is controlled to bring the long-diameter end of the abutment roller closer to the sliding plate, pushing the sliding plate to the left. This causes the spring plates to slide within the side grooves, stretching the springs for retraction. Simultaneously, the retaining ring slides towards the electric rotating rod, locking itself in place by the grooves on the surface of the retaining ring, ensuring the stability of the lifting device after directional adjustment.

[0029] 2. By using the set first conical roller, second conical roller, screw, insert plate, side plate and clamping plate, when it is necessary to lift building parts of different thicknesses, the second motor is controlled to drive the first conical roller connected to it to rotate, which in turn drives the second conical rollers on both sides to rotate, which in turn drives the screw connected to them to rotate, and the insert plate to slide in the groove. With the side plate embedded in the side groove, the front and rear clamping plates can be adjusted to stably and firmly clamp building parts of different thicknesses, thereby increasing the stability and range of lifting.

[0030] 3. By using the telescopic plate, toothed plate, electric toothed roller, limiting plate and support plate, after the building components are clamped and fixed at the front and rear, the electric toothed roller is controlled to rotate so that it meshes with the toothed plate. Under the limiting position of the limiting plate embedded in the limiting groove, the support plate installed at the lower end is driven to adjust up and down stably, so that the support plate abuts against the lower surface of the building components, effectively supporting the lower side of the building components and improving the stability of the hoisting process.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0040] Therefore, the following detailed description of embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely illustrates some embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] like Figure 1-6As shown, this embodiment proposes a high-stability hoisting device for building renovation and its operation method, including a base 1, a vertical pole 2 fixedly installed on the upper end of the base 1, a top plate 3 rotatably installed on the upper end of the vertical pole 2, a directional adjustment component provided on the lower side of the top plate 3 away from the vertical pole 2, a crossbeam 5 installed at the lower end of the directional adjustment component, an electric adjustment plate 6 telescopically provided at both ends of the crossbeam 5, a fixing plate 7 fixedly installed at the lower end of the electric adjustment plate 6, a clamping component provided on the side wall of the fixing plate 7, and a base support component provided at the lower end of the fixing plate 7.

[0044] like Figure 2 As shown, the directional adjustment assembly includes a vertical rod 401 installed at the lower end of the top plate 3. An electric rotating rod 402 is rotatably provided on the lower side of the vertical rod 401 to control the rotation of the electric rotating rod 402 to adjust the direction of hoisting building components.

[0045] like Figure 3 As shown, an outer plate 403 is installed on the outer wall of the vertical rod 401. A groove 404 is provided on the lower side of the outer plate 403. An abutment roller 405 is provided at the end of the groove 404 away from the vertical rod 401. A first motor 406 is connected to the upper end of the abutment roller 405. Controlling the first motor 406 to drive the elliptical abutment roller 405 to rotate, so that its short diameter end approaches the slide plate 407, the springs on the side walls of the front and rear spring plates 409 contract, and the slide plate 407 slides away from the electric rotating rod 402. This causes the retaining ring 410 to disengage from the surface of the electric rotating rod 402, and the rotation of the electric rotating rod 402 can be controlled to adjust the direction of hoisting building accessories. After adjustment, controlling the first motor 406 to drive the long diameter end of the abutment roller 405 to approach the slide plate 407 can push the slide plate 407 to the left, causing the spring plate 409 to slide in the side groove 408 and produce a stretching effect on the spring.

[0046] like Figure 3 As shown, a sliding plate 407 is slidably disposed inside the slide groove 404 near one end of the vertical rod 401. Side grooves 408 are provided on the front and rear sides of the slide groove 404. Spring plates 409 that cooperate with the side grooves 408 are provided on the front and rear sides of the sliding plate 407. A retaining ring 410 that cooperates with the electric rotating rod 402 is fixedly installed at the lower end of the sliding plate 407. The retaining ring 410 slides towards the electric rotating rod 402 and is locked in place by the retaining pattern on the surface of the retaining ring 410, which is embedded in the pattern on the surface of the electric rotating rod 402 to ensure the stability of the hoisting device after the direction is adjusted.

[0047] like Figure 4As shown, the clamping assembly includes a connecting frame 801 mounted on the surface of the fixing plate 7 near the upright 2. The connecting frame 801 has a central groove 802 in the center. A first conical roller 803 is provided on the inner wall of the upper end of the central groove 802. A second motor 804 is connected to the upper end of the conical roller. Second conical rollers 805 that cooperate with the first conical roller 803 are provided on the inner walls of both sides of the central groove 802. When it is necessary to hoist building components of different thicknesses and sizes, the second motor 804 is controlled to rotate, driving the first conical roller 803 connected to it to rotate, and meshing to drive the second conical rollers 805 on both sides to rotate.

[0048] like Figure 4 As shown, the central groove 802 has grooves 806 on both sides. A screw 807 is rotatably installed inside the groove 806. A plate 808 is fitted on the outer wall of the screw 807. A clamping plate 811 is installed on the outer wall of the plate 808. When the screw 807 rotates, it engages and drives the plate 808 to slide in the groove 806. With the side plate 810 embedded in the side groove 809, the front and rear clamping plates 811 can be stably adjusted to clamp building accessories of different thicknesses and sizes.

[0049] like Figure 4 As shown, the side wall of the groove 806 is provided with a side groove 809, and the side wall of the plate 808 is provided with a side plate 810 that cooperates with the side groove 809. With the side plate 810 embedded in the side groove 809, the front and rear clamping plates 811 can be stably adjusted to clamp building accessories of different thicknesses and sizes, thereby increasing the stability and range of hoisting.

[0050] like Figure 5 As shown, the base support assembly includes a telescopic groove 901 opened inside the lower side of the fixed plate 7. A telescopic plate 902 is slidably disposed inside the telescopic groove 901. A support plate 908 is installed on the lower outer wall of the telescopic plate 902. The support plate 908 abuts against the lower surface of the building component, effectively supporting the lower side of the building component.

[0051] like Figure 6 As shown, an electric toothed roller 905 is rotatably installed inside the telescopic groove 901 on the side away from the upright 2. A slot 903 is opened on the side of the telescopic plate 902 near the electric toothed roller 905. A toothed plate 904 that cooperates with the electric toothed roller 905 is provided inside the slot 903. Limiting grooves 906 are opened on the front and rear sides of the telescopic groove 901. Limiting plates 907 that cooperate with the limiting grooves 906 are provided on the front and rear sides of the telescopic plate 902. Under the limitation of the limiting plate 907 being embedded in the limiting groove 906, the support plate 908 installed at the lower end is driven to adjust up and down stably, so that the support plate 908 abuts against the lower surface of the building component, effectively supporting the lower side of the building component and improving the stability of the hoisting process.

[0052] A method for operating a high-stability hoisting device for building renovation includes the following steps:

[0053] Step 1: When it is necessary to adjust the hoisting direction of the modified building components, control the first motor 406 to drive the elliptical contact roller 405 to rotate, so that its short diameter end is close to the slide plate 407. The springs on the side walls of the front and rear spring plates 409 contract, causing the slide plate 407 to slide away from the electric rotating rod 402. This will cause the retaining ring 410 to disengage from the surface of the electric rotating rod 402, and the rotation of the electric rotating rod 402 can be controlled to adjust the hoisting direction of the building components.

[0054] Step 2: After adjustment, control the first motor 406 to operate so that the long diameter end of the contact roller 405 is close to the slide plate 407. Then, push the slide plate 407 to the left, causing the spring plate 409 to slide in the side groove 408 to stretch the spring so that it can retract and operate. At the same time, drive the retaining ring 410 to slide towards the electric rotating rod 402. The retaining ring 410 is locked in the groove on the surface of the electric rotating rod 402 by the retaining pattern on the surface of the retaining ring 410.

[0055] Step 3: When it is necessary to hoist building components of different thicknesses and sizes, control the second motor 804 to drive the first conical roller 803 connected to it to rotate, and mesh with it to drive the second conical rollers 805 on both sides to rotate.

[0056] Step 4: Drive the screw 807 connected to it to rotate, and drive the insert 808 to slide in the groove 806. With the side plate 810 embedded in the side groove 809, the front and rear clamping plates 811 can be adjusted to a stable and firm distance so as to clamp building accessories of different thicknesses and sizes.

[0057] Step 5: After the building components are clamped and fixed at the front and rear, control the electric toothed roller 905 to rotate so that it meshes with the toothed plate 904. Under the limitation of the limiting plate 907 embedded in the limiting groove 906, the lower end of the support plate 908 is driven to adjust up and down stably, so that the support plate 908 abuts against the lower end surface of the building components, effectively supporting the lower side of the building components.

[0058] Specifically, when using this hoisting device: When it is necessary to adjust the hoisting direction of the modified building components, the first motor 406 is controlled to rotate, causing the elliptical contact roller 405 to rotate, bringing its short-diameter end closer to the sliding plate 407. The springs on the side walls of the front and rear spring plates 409 contract, causing the sliding plate 407 to slide away from the electric rotating rod 402. This allows the retaining ring 410 to disengage from the surface of the electric rotating rod 402, enabling the electric rotating rod 402 to rotate and adjust the direction of the hoisted building components. After adjustment, the first motor 406 is controlled to rotate, bringing the long-diameter end of the contact roller 405 closer to the sliding plate 407. This pushes the sliding plate 407 to the left, causing the spring plate 409 to slide within the side groove 408, stretching the springs for retraction. Simultaneously, the retaining ring 410 slides towards the electric rotating rod 402, locking itself in place by the grooves on its surface, ensuring the hoisting device... After directional adjustment, the stability is improved. When hoisting building components of different thicknesses, the second motor 804 is controlled to rotate, driving the first conical roller 803 connected to it to rotate. This meshes with the second conical rollers 805 on both sides, causing the screw 807 connected to them to rotate. This meshes with the insert plate 808, which slides in the groove 806. With the side plate 810 embedded in the side groove 809, the front and rear clamping plates 811 are stably adjusted to securely clamp building components of different thicknesses, thereby increasing the stability and range of hoisting. After the building components are clamped and fixed, the electric toothed roller 905 is controlled to rotate, meshing with the toothed plate 904. With the limiting plate 907 embedded in the limiting groove 906, the lower end mounting plate 908 is stably adjusted up and down, allowing the plate 908 to abut against the lower surface of the building component, effectively supporting the lower side of the building component and improving the stability of the hoisting process.

[0059] All technical features in this embodiment can be freely combined according to actual needs.

[0060] The above embodiments are preferred implementations of the present invention. In addition, the present invention can be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.

Step 3: When it is necessary to hoist building components of different thicknesses and sizes, control the second motor (804) to drive the first conical roller (803) connected to it to rotate, and mesh with it to drive the second conical rollers (805) on both sides to rotate. Step 4: Drive the screw (807) connected to it to rotate, and drive the insert (808) to slide in the groove (806). Under the limit of the side plate (810) being embedded in the side groove (809), the front and rear clamping plates (811) can be stably adjusted to clamp building accessories of different thicknesses and sizes stably and firmly. Step 5: After the building components are clamped and fixed at the front and rear, control the electric toothed roller (905) to rotate so that it meshes with the toothed plate (904) on the surface. Under the limit of the limiting plate (907) embedded in the limiting groove (906), the lower end of the support plate (908) is driven to adjust up and down stably, so that the support plate (908) abuts against the lower end surface of the building components, effectively supporting the lower side of the building components.
