Description

Technical Field

[0001] This invention relates to the field of hoisting technology for building construction materials, and in particular to a hoisting device suitable for building construction materials of various specifications. Background Technology

[0002] In the construction of prefabricated buildings, the hoisting of various prefabricated panels (such as prefabricated composite floor slabs, exterior wall panels, and interior wall panels) is an essential part of the construction process. Currently, most existing panel hoisting devices adopt fixed hanger structures, which are used in conjunction with wire ropes, slings, or special clamps to bind or clamp the panels for hoisting. These traditional devices have many shortcomings in practical use.

[0003] Firstly, the structural dimensions of fixed hangers cannot be adjusted. When the specifications of the panels change, it is necessary to replace them with different models of hangers or readjust the lifting points, which is cumbersome and inefficient, seriously affecting the construction progress. Secondly, existing clamps are mostly rigid clamps, which are poorly adaptable to panels of different thicknesses and surface conditions. The clamping force is difficult to control, which can easily cause damage to the edges of the panels or unstable clamping. Thirdly, most hoisting devices rely solely on a single hook or clamp to restrain the panels, lacking effective auxiliary stabilization measures. During hoisting, the panels are prone to shaking or even slipping, posing significant safety hazards. Therefore, we propose a hoisting device suitable for building construction with panels of various specifications. Summary of the Invention

The sliding adjustment component includes a connecting plate and an electric push rod. The connecting plate is slidably disposed on the upper side of the mounting frame, and the electric push rod pushes and pulls the connecting plate to adapt to the hoisting of the plate. The adjustment component includes a movable groove, on the inner side of which a movable plate is equidistantly slidably installed.

A power supply module is symmetrically fixedly mounted on the upper side of the mounting frame, and the power supply module is connected to the electric actuator circuit via wires. A level is symmetrically fixedly mounted on the upper side of the power supply module.

[0008] Furthermore, the movable slots are symmetrically opened on the inner side of the mounting frame, and the trigger locking component includes an inner cavity mirror-opened on both sides of the movable plate corresponding to the movable slot wall position. A constraint rod is slidably installed inside the inner cavity. One side of the constraint rod is inclined. A first spring is fixedly connected between the side of the constraint rod and the inner cavity wall. The first spring is movably sleeved on the side of the constraint rod.

[0009] Furthermore, the trigger locking component also includes symmetrical slots on the upper side of the movable plate corresponding to the inner cavity position. A trigger plate is movably arranged inside the slot. A second spring is symmetrically fixedly installed on the lower side of the trigger plate. The other end of the second spring is fixedly connected to the bottom wall of the slot. A constraint block is fixedly installed on the lower side of the trigger plate. The constraint block extends through the movable plate into the inner cavity and fits against the inclined surface of the constraint rod.

[0010] Furthermore, the rotating component includes a fixed shaft fixedly installed on the lower side of the movable frame. Indicator grooves are equidistantly provided on the side of the fixed shaft. A second adjusting block is movably sleeved on the outer side of the fixed shaft. Spline blocks are fixedly installed equidistantly on the inner side of the second adjusting block. The spline blocks are snapped into the inside of the indicator grooves. A limit plate is fixedly installed on the inner side of the second adjusting block. The limit plate is movably sleeved on the side of the fixed shaft. A pull rod is symmetrically arranged on the side of the second adjusting block. The pull rod passes through the second adjusting block to its interior. A limit block is fixedly installed on the side of the pull rod. The limit block is located between the lower side of the limit plate and the inner side of the fixed shaft. A first support cylinder is movably sleeved on the side of the pull rod. The first support cylinder is located between the side of the limit block and the inner side of the second adjusting block.

[0011] Furthermore, the suction component includes a connecting rod fixedly installed at the center of the lower side of the second adjusting block. A movable cavity is opened on the lower side of the connecting rod, and a movable rod is movably arranged inside the movable cavity. The movable rod extends out of the interior of the movable cavity, and a second support cylinder is fixedly connected between the upper side of the movable rod and the top wall of the movable cavity.

[0012] Furthermore, the hooking component includes mating grooves mirror-shaped on both sides of the connecting rod, bolts are movably installed inside the mating grooves, hook brackets are movably sleeved on the sides of the mating grooves, limit grooves are equidistantly opened on the sides of the hook brackets corresponding to the bolt positions, limit holes are symmetrically opened on the sides of the connecting rod corresponding to the mating groove positions, limit rods are threadedly installed inside the limit grooves, and the limit rods are inserted into the corresponding limit holes.

[0013] Compared with the prior art, the beneficial effects that this invention can achieve are: 1. This invention achieves flexible adaptation and stable lifting of various specifications of sheet metal through the coordinated operation of the main hanger, main frame assembly, adjustment assembly, and lifting assembly. The adjustment assembly can freely adjust its position according to the specifications of the sheet metal and lock itself in place. The lifting assembly has dual lifting functions of suction nozzle adsorption and hook frame mechanical constraint. Combined with the shear-type dynamic center of gravity compensation mechanism of the main hanger, it improves the adaptability of the lifting device to different specifications of sheet metal and the safety and stability of the lifting process, solving the problems of poor versatility and insufficient safety of traditional lifting tools.

[0014] 2. The present invention allows the movable plate in the adjustment component to slide and adjust within the movable groove, and the self-locking fixation is achieved by pressing the trigger plate to drive the constraint rod to squeeze the wall of the movable groove. At the same time, the movable frame in the hoisting component can be further slid and adjusted on the movable plate to make the suction nozzle accurately correspond to the required suction point of the board. The dual position adjustment mechanism enables the device to flexibly adapt to boards of different sizes and specifications, improving the versatility and on-site adaptability of the hoisting device.

[0015] 3. In this invention, the suction nozzle in the hoisting assembly, through the elastic cooperation between the movable rod and the second support cylinder, can obtain buffering and closely adhere to the surface of the plate when in contact with it, forming an initial adsorption constraint on the plate. At the same time, the hook frame can slide and rotate along the mating groove and be locked by the cooperation of the limiting rod and the limiting hole, forming a further mechanical hook constraint from the side of the plate. The dual insurance mechanism of adsorption and hook enhances the reliability of the constraint on the plate during hoisting and effectively prevents the plate from slipping and falling.

[0016] 4. This invention, through the engagement of the second adjusting block with the spline block and the indicator groove, and the limiting action of the limiting block on the limiting plate, enables the hook frame to be freely adjusted and firmly positioned at multiple angles in the circumferential direction. This allows the hook frame to flexibly adjust its orientation according to the actual shape of the plate and the position of the lifting point, ensuring that the hook frame is accurately attached to the reasonable force position on the side of the plate, further improving the device's adaptability to different specifications of plates and its lifting stability.

[0017] 5. This invention uses electric actuators symmetrically arranged on the mounting frame in the main frame assembly, in conjunction with a level, to detect the horizontal state of the mounting frame in real time. When the mounting frame tilts, the electric actuators drive the connecting plate to move and cause the main hanger to rotate in a shearing manner, thereby achieving precise compensation for the offset of the hoisting center of gravity. This ensures that the plate remains horizontal throughout the hoisting and transportation process, avoiding tilting of the plate and difficulties in positioning caused by the offset of the center of gravity, and improving hoisting accuracy and safety.

[0020] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0021] Example: Figures 1 to 3 As shown, a hoisting device for building construction suitable for multi-specification boards includes a main hanger 1, which is a shear-type hanger, and is generally "X" shaped. A circular shaft is set at the center to support the rotation of the components. A lifting ring 11 is fixedly installed on the top of the main hanger 1. A main frame assembly 2 is set below the main hanger 1. The main frame assembly 2 can be adjusted and compensated for as a whole. An adjustment component 3 is set on the inner side of the main frame assembly 2. The adjustment component 3 can be self-locked after free adjustment. Hoisting components 4 are equidistantly arranged on the side of the adjustment component 3. The hoisting components 4 can hoist and constrain different boards.

[0022] like Figures 2 to 5As shown, the main frame assembly 2 includes a mounting frame 21, which is a U-shaped frame structure. An adjustment groove 22, which is an "L"-shaped groove, is mirror-imagely opened on the upper side of the mounting frame 21. A first adjustment block 221, also an "L"-shaped block, is symmetrically slidably installed inside the adjustment groove 22. A connecting plate 23 is symmetrically arranged on the lower side of the main hanger 1 and is fixedly installed on the upper side of the corresponding first adjustment block 221. The main hanger 1 is rotatably connected to the connecting plate 23 via a "U"-shaped plate. Electric actuators 24 are symmetrically fixedly arranged on the upper side of the mounting frame 21, with the output end of the electric actuators 24 facing the connecting plate 23. A pressure sensor 241 is fixedly connected to the output end of the electric actuator 24 and is fixedly installed on the connecting plate 23. On the side of plate 23, a power supply module 25 is symmetrically fixedly installed on the upper side of the mounting bracket 21, and the power supply module 25 is connected to the electric push rod 24 by wires. A level 26 is symmetrically fixedly installed on the upper side of the power supply module 25. Specifically, the power supply module 25 directly supplies power to the electric push rod 24, and the level 26 detects the overall level of the mounting bracket 21. Then, a set of electric push rods 24 on the side of the connecting plate 23 pushes and pulls to move the corresponding connecting plate 23. The connecting plate 23 is constrained by the sliding of the first adjusting block 221 in the adjusting groove 22, which drives the main hanger 1 to perform shearing rotation, thereby compensating for the offset of the center of gravity of the mounting bracket 21. In addition, the pressure sensor 241 detects the pressure value in real time to determine the pushing and pulling state of the electric push rod 24.

[0023] like Figures 2 to 4 and Figures 6 to 9As shown, the adjustment component 3 includes a movable groove 31, which is symmetrically located inside the mounting bracket 21. The movable groove 31 is a rectangular groove. A movable plate 32, also a rectangular plate, is equidistantly slidably installed inside the movable groove 31. An inner cavity 33 is mirror-shaped on both sides of the movable plate 32 corresponding to the wall of the movable groove 31. The inner cavity 33 is a cylindrical groove with a "T"-shaped cross-section. A constraint rod 35, also a "T"-shaped cylindrical rod, is slidably installed inside the inner cavity 33. One side of the constraint rod 35 is inclined. A first spring 351 is fixedly connected between the side of the constraint rod 35 and the wall of the inner cavity 33, and the first spring 351 is movably sleeved on the side of the constraint rod 35. A slot 34, also a rectangular groove, is symmetrically located on the upper side of the movable plate 32 corresponding to the position of the inner cavity 33. A trigger plate 36, also a rectangular plate, is movably disposed inside the slot 34. A second spring 361 is symmetrically fixedly installed on the lower side of the trigger plate 36, and the other end of the second spring 361 is fixedly connected to the bottom wall of the slot 34. A constraint block 37 is fixedly installed on the lower side of the trigger plate 36, and the constraint block 37 extends through the movable plate 32 to the inner cavity 33. The constraint block 37 is attached to the inclined surface of the constraint rod 35 and is a trapezoidal block. Specifically, by pressing the trigger plate 36 to move it downward, the trigger plate 36 drives the constraint block 37 to squeeze the constraint rod 35, so that the constraint rod 35 slides outward inside the inner cavity 33. The constraint rod 35 is squeezed to the wall of the movable slot 31 to complete the fixation of the movable plate 32. The first spring 351 and the second spring 361 provide elastic support for the constraint rod 35 and the trigger plate 36. When the trigger plate 36 is not squeezed, the constraint rod 35 and the trigger plate 36 are reset by the elastic support of the first spring 351 and the second spring 361.

[0024] like Figure 2 , Figure 3 , Figure 6 and Figures 9 to 13As shown, the hoisting assembly 4 includes a movable frame 41, which is movably sleeved on the side of the movable plate 32. The movable frame 41 is a U-shaped frame. A trigger rod 411 is threaded through the upper side of the movable frame 41 and is positioned corresponding to the trigger plate 36. The trigger rod 411 is a cylindrical threaded rod with a "T"-shaped cross-section. A fixed shaft 42 is fixedly installed on the lower side of the movable frame 41. The fixed shaft 42 is a cylindrical shaft with an "I"-shaped cross-section. Indicator slots 421 are equidistantly arranged in a circular array on the side of the fixed shaft 42. The indicator slots 421 are rectangular slots. A second adjusting block 43 is movably sleeved on the outer side of the fixed shaft 42. The second adjusting block 43 is a round block with a hollow upper side. Spline blocks 431 are fixedly installed in a circumferential array at equal intervals on the inner side of the second adjusting block 43, and the spline blocks 431 are snapped into the inside of the indicator groove 421. A limiting plate 432 is fixedly installed on the inner side of the second adjusting block 43, and the limiting plate 432 is movably sleeved on the side of the fixed shaft 42. The limiting plate 432 is in contact with one side of the fixed shaft 42. A pull rod 44 is symmetrically arranged on the side of the second adjusting block 43 and passes through the second adjusting block 43 to its interior. A limiting block 441 is fixedly installed on the side of the pull rod 44, and the limiting block 441 is located between the lower side of the limiting plate 432 and the inner side of the fixed shaft 42. The limiting block 441 is an arc-shaped block. A first support cylinder 442 is movably sleeved on the side of the pull rod 44, and the first support cylinder 442 is located between the side of the limiting block 441 and the inner side of the second adjusting block 43. The first support cylinder 442 is a corrugated tube made of elastic material. Specifically, pulling the pull rod 44 causes the limiting block 441 to disengage from the lower side of the limiting plate 432 and the inner side of the fixed shaft 42. At this time, the second adjusting block 43 can be pulled downwards, so that... Spline block 431 disengages from inside indicator groove 421. Limiting block 441 is elastically supported by first support cylinder 442 and adheres to the side of fixed shaft 42. Rotate second adjusting block 43 to adjust direction. Then move second adjusting block 43 upward so that corresponding spline block 431 is engaged inside indicator groove 421. Simultaneously, limiting block 441 is elastically supported by first support cylinder 442 and slides into the lower side of limiting plate 432 and the inner side of fixed shaft 42 to adhere. Limiting plate 432 by limiting block 441 allows second adjusting block 43 to be restricted and locked to the side of fixed shaft 42. A connecting rod 45 is fixedly installed at the lower center of the second adjusting block 43. The connecting rod 45 is a cross-shaped cylindrical rod. A movable cavity 46 is opened on the lower side of the connecting rod 45. The movable cavity 46 is a cylindrical groove with a convex cross section. A movable rod 461 is movably arranged inside the movable cavity 46 and extends out of the interior of the movable cavity 46. The movable rod 461 is a T-shaped cylindrical threaded rod. A second support cylinder 462 is fixedly connected between the upper side of the movable rod 461 and the top wall of the movable cavity 46. The second support cylinder 462 is a corrugated tube of elastic material. A suction nozzle 463 is threadedly sleeved on the lower side of the movable rod 461. Specifically, the suction nozzle 463 can be used to suction and constrain the stacked plate after demolding. The suction nozzle 463 presses downward on the side of the stacked plate. The movable rod 461 slides and squeezes the second support cylinder 462 inside the movable cavity 46 to deform it, so that the suction nozzle 463 can better suction the side of the stacked plate. The connecting rod 45 has mirror-image mating grooves 47 on both sides. The mating grooves 47 are U-shaped grooves. Bolts 471, a combination of screws and nuts, are movably installed inside the mating grooves 47. Hook brackets 48, U-shaped with a hook-like lower side, are movably sleeved on the side of the mating grooves 47. Limiting grooves 481, cylindrical threaded grooves, are equidistantly arranged in a circular array on the side of the hook brackets 48 corresponding to the positions of the bolts 471. Limiting holes 49, cylindrical holes, are symmetrically arranged on the side of the connecting rod 45 corresponding to the positions of the mating grooves 47. Limiting rods 482 are threadedly installed inside the limiting grooves 481 and inserted to the corresponding limit. The internal position of the positioning hole 49; specifically, the limiting groove 481 is rotated inside the hook frame 48 to disengage from the limiting hole 49. Then, the nut of the bolt 471 is loosened. At this time, the bolt 471 slides inside the mating groove 47, causing the hook frame 48 to move. The hook frame 48 can rotate and hang on the side of the bolt 471 inside the mating groove 47 to constrain the side of the corresponding composite plate. The corresponding limiting groove 481 is turned to the hook frame 48 at the position of the corresponding limiting hole 49, thus completing the limiting of the hook frame 48. Finally, the nut of the bolt 471 is tightened to fully lock it. In this way, the composite plate is first lifted by suction and constraint through the suction nozzle 463, and then the side of the composite plate is further constrained and restricted by the hook frame 48.

[0025] Working principle: In use: First, adjust the fit. Depending on the type and size of the composite plate, turn the trigger rod 411 to prevent it from pressing against the side of the trigger plate 36. At this time, the corresponding constraint rod 35 and the trigger plate 36 are elastically supported and reset by the first spring 351 and the second spring 361. The movable plate 32 can slide and adjust its position inside the movable groove 31 to correspond to the side position of the composite plate. Then, the movable frame 41 slides on the side of the movable plate 32 so that the suction nozzle 463 corresponds to the required suction point. Then, turn the trigger rod 411 to press it against the side of the trigger plate 36. The trigger plate 36 slides downward under pressure, and the constraint block 37 can press the constraint rod 35 outward inside the inner cavity 33. The constraint rod 35 presses against the wall of the movable groove 31 to fix and constrain the movable plate 32. In addition, according to the specifications of the composite plate, the electric push rod 24 pushes and pulls the connecting plate 23 to move its position, so that the main hanger 1 performs shearing rotation. This is suitable for the lifting and use of composite plates. The second step involves hoisting the material. Based on the position of the hook frame 48 corresponding to the side of the stacked plate, pull the lever 44 to cause the limiting block 441 to press and deform the first support cylinder 442, disengaging it from the lower side of the limiting plate 432 and the inner side of the fixed shaft 42. At this time, the second adjusting block 43 can be pulled downwards to disengage from the side of the fixed shaft 42, and the spline block 431 disengages from the inside of the indicator groove 421. Rotating the second adjusting block 43 causes the hook frame 48 to adjust its direction. The limiting block 441 then adheres to the side of the fixed shaft 42 without limiting the limiting plate 432. After the second adjusting block 43 rotates to the corresponding position, it is pressed upwards to cause the spline block 431 to engage and insert into the inside of the indicator groove 421. At this time, the limiting block 441 is elastically supported by the first support cylinder 442 and adheres to the lower side of the limiting plate 432 and the inner side of the fixed shaft 42. The limiting block 441 limits the limiting plate 432, causing the second adjusting block 43 to engage and be locked in place. At the side position of the fixed shaft 42; then the mounting bracket 21 moves downward as a whole, so that the trigger plate 36 of the adjusting component 3 is attached to the side of the stacked plate. The trigger plate 36 is pressed in the opposite direction by the stacked plate, and slides in the slot 34 through the second spring 361, so that the trigger plate 36 obtains elastic buffer, thereby better attaching to the surface of the stacked plate, providing elastic support for the suction nozzle 463 so that it can quickly attach to the side of the stacked plate. After the suction nozzle 463 attaches to the stacked plate, it is slightly lifted with assistance; finally, the nut of the bolt 471 is loosened, so that the bolt 471 slides in the mating groove 47, and the hook frame 48 rotates and hangs on the side of the stacked plate. At this time, the limiting groove 481 is screwed into the hook frame 48 corresponding to the limiting hole 49. The limiting groove 481 is inserted into the limiting hole 49 to complete the limiting of the hook frame 48. The nut of the bolt 471 is tightened to completely lock the hook frame 48. The third step is stable hoisting. The side of the composite plate is constrained by the hook frame 48, and the composite plate is attracted and stabilized by the suction nozzle 463. The crane can lift the main hanger 1 as a whole through the lifting ring 11. At this time, the composite plate is lifted and moved. During the movement, the overall horizontal status of the mounting frame 21 is detected by the level 26. When the horizontal position of the mounting frame 21 deviates, the corresponding electric push rod 24 can push and pull the connecting plate 23 to move. The connecting plate 23 is constrained by the sliding of the first adjusting block 221 inside the adjusting groove 22. This compensates for the center of gravity of the mounting frame 21 and ensures that the mounting frame 21 and the composite plate material on its side are hoisted horizontally. The above device can also be used to hoist other different types of boards.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
