Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a hoisting device for concrete wall panels. Background Art

[0002] Precast concrete wall panels are reinforced concrete plate-type components processed in precast plants (yards) or construction sites for building assembly. Through rapid assembly, they can shorten the construction period and improve the degree of factory-based and mechanized construction.

[0003] In recent years, autoclaved aerated concrete wall panels (ALC wall panels for short) have been widely used in the market; ALC wall panels are a lightweight, porous, green and environmentally friendly building material. They are made of cement, lime, silica sand (or stone powder, fly ash, slag, etc.) as the main raw materials, with appropriate amounts of gas generating agents and bubble stabilizers added. According to structural requirements, steel mesh cages or steel mesh sheets treated with rust-proof coatings are configured in the casting mold. After the process of batching, mixing, pouring, gas generation, stopping, cutting and high-pressure steaming, a porous, lightweight silicate prefabricated panel is finally made, which has good thermal insulation and sound insulation properties.

[0004] As a lightweight prefabricated wall panel, the ALC wall panel has a relatively weak structural strength. During the hoisting construction process, care should be taken to prevent the panels from being subjected to excessive impact or pressure to reduce the possibility of deformation, cracks, or even breakage or damage to the panels. Existing construction hoisting usually involves opening lifting holes in the ALC wall panels, or installing lifting rings on the top of the ALC wall panels for the hooks of lifting equipment to hook on. However, when the ALC wall panels are hoisted, the corners of the ALC wall panels are easily bumped and damaged, which affects the aesthetics and usability of the ALC wall panels and needs to be improved. Summary of the invention

[0005] Based on this, the present application provides a hoisting device for concrete wall panels, which can reduce the occurrence of bumps and damages to the corners of the ALC wall panels during the hoisting process, so as to ensure the aesthetics and usability of the ALC wall panels.

[0006] The present application provides a concrete wall panel hoisting device that adopts the following technical solution:

[0007] A hoisting device for a concrete wall panel comprises a hanger unit, a limit unit and a base unit, wherein the hanger unit comprises a hanger and a hoisting ring arranged on the side of the hanger, and the hoisting ring is used for hooking with a hook of an external hoisting device;

[0008] The base unit includes a base mechanism, the base mechanism is provided with a placement slot for placing the wallboard, and the base mechanism is provided with a limit stopper for the wallboard to abut against and limit the position; a disassembly mechanism is provided between the base mechanism and the suspension frame to achieve detachable fixation between the two;

[0009] The limiting unit includes a top seat mechanism vertically movably arranged on the suspension frame and a driving mechanism for driving the top seat mechanism to move vertically. The top seat mechanism is provided with a receiving groove for accommodating the wall panel. When the lifting operation is carried out, the two opposite sides of the wall panel are respectively located in the placement groove and the receiving groove.

[0010] By adopting the above-mentioned technical scheme, when the ALC wall panel is hoisted, the present application first places the ALC wall panel in the placement groove of the base mechanism, so that the ALC wall panel abuts against the limit stopper of the base mechanism, thereby realizing the preliminary positioning of the ALC wall panel; then, the base mechanism is fixed to the suspension frame by using the disassembly and assembly mechanism, and the driving mechanism is controlled to operate so that the top seat mechanism moves downward and gradually approaches the ALC wall panel, and the ALC wall panel can enter the accommodating groove of the top seat mechanism, and then in the process of the lifting hook of the lifting equipment hooking on the lifting ring of the suspension frame and lifting the lifting device, the two side edges and corners of the ALC wall panel can be protected by the base mechanism and the top seat mechanism, thereby reducing the occurrence of bumps and damages on the corners of the ALC wall panel, thereby ensuring the aesthetics and usability of the ALC wall panel.

[0011] Optionally, the top seat mechanism includes two groups of top seat components that are symmetrically arranged, the two groups of top seat components are movably connected through a first shaft rod, and a first adjustment component for adjusting the spacing is commonly provided between the two groups of top seat components;

[0012] Among them, the top seat assembly includes a crimping seat vertically movably arranged on the suspension frame and two L-shaped stop seats arranged on opposite sides of the crimping seat, and each L-shaped stop seat is movably connected to the crimping seat through a second shaft rod; when the lifting operation is in progress, the crimping seat rests against the side of the wall panel, and the two L-shaped stop seats respectively rest against the two corners of the wall panel.

[0013] By adopting the above-mentioned technical scheme, by controlling the first adjustment component to adjust the distance between the two groups of top seat components, it is possible to adapt to the lifting of ALC wall panels of different thicknesses; and by controlling the driving mechanism to move the two groups of L-shaped stop seats toward the crimping seat, it is possible to adapt to the lifting of ALC wall panels of different lengths and widths, so that the ALC wall panels are firmly placed inside the accommodating groove, thereby improving the practicability of the lifting device, and being applicable to the lifting operations of ALC wall panels of various types and sizes.

[0014] Optionally, the base mechanism includes two symmetrically arranged groups of base assemblies, the two groups of base assemblies are movably connected by a third axis rod, and a second adjustment assembly for adjusting the spacing is commonly provided between the two groups of base assemblies; wherein the base assembly includes a movable base and a supporting seat slidably arranged on the top of the movable base, and the limit stop seat is fixedly arranged on the top of the supporting seat.

[0015] By adopting the above-mentioned technical scheme, the second adjustment component is controlled to adjust the distance between the two groups of base components, so that the ALC wall panel can fit against the two opposite side walls of the placement groove after being placed in the placement groove, thereby being adapted to the stable placement of ALC wall panels of various thicknesses, and being suitable for the hoisting operation of ALC wall panels of various types and sizes; in addition, when the base mechanism is fixed to the suspension frame through the disassembly and assembly structure, there is a situation where the center line of the ALC wall panel and the center line of the clamping seat are misaligned, and in the process of the crimping seat moving downward and gradually abutting against the ALC wall panel, the two L-shaped stoppers can approach each other, and one of the L-shaped stoppers will abut against the ALC wall panel and drive the ALC wall panel and the supporting seat to move horizontally, thereby reducing the friction damage between the ALC wall panel and the movable base, and is also beneficial for the ALC wall panel to maintain good aesthetics and usability.

[0016] Optionally, the driving mechanism includes a mounting base mounted on the side of the suspension frame, a hand-screw rod rotatably mounted on the mounting base, and an adjustment base movably arranged on the mounting base, the axis direction of the hand-screw rod is arranged in the same direction as the vertical direction, and the hand-screw rod is passed through the adjustment base and is threadedly connected to the adjustment base;

[0017] A movable plug is fixed on the top of the crimping seat, and the movable plug is movably inserted into the adjustment base. A reset spring is provided between the movable plug and the adjustment base, and the reset spring is used to force the crimping seat to normally abut against the adjustment base; two hinged arm plates are hinged on the side of the adjustment base, and one end of each hinged arm plate away from the adjustment base is hinged to the L-shaped stop seat;

[0018] A plurality of first rope pulleys are arranged on the side of the supporting seat, and a plurality of second rope pulleys are arranged on the side of the top seat assembly; the driving mechanism also includes a steel rope and a reel, the reel is fixed to the mounting base, one end of the steel rope is fixedly connected to the top seat assembly, and the other end of the steel rope is fixedly connected to the rotating end of the reel; when the lifting operation is in progress, the steel rope is in a taut state and is alternately wound around each first rope pulley and each second rope pulley in turn.

[0019] By adopting the above-mentioned technical scheme, the hoisting operation is usually carried out within a period of time for ALC wall panels of the same model and size. At this time, the base mechanism equipped with the ALC wall panel is pre-fixed on the suspension frame, and the distance between the top seat mechanism and the base mechanism can be changed by rotating the hand screw to change the position of the adjustment base; at this time, the top seat mechanism is forced to move in the direction close to the ALC wall panel, and the positions of the two L-shaped stoppers can be observed when the crimping seat is pressed against the ALC wall panel. Continuing to rotate the hand screw can adjust the two L-shaped stoppers to a position that fits the ALC wall panel.

[0020] During the hoisting operation, the base mechanism equipped with the ALC wall panel is fixed to the suspension frame. In the initial state, the steel strands are in a relaxed state. At this time, the steel strands are manually wound around the first rope pulleys and the second rope pulleys in turn, and the reel is controlled to tighten the steel strands, which can force the top mechanism to move closer to the base mechanism. Finally, the two side edges and corners of the ALC wall panel can be protected by the base mechanism and the top mechanism, so as to facilitate the hoisting of the ALC wall panel and reduce the bumps and losses of the ALC wall panel during the hoisting process.

[0021] Optionally, the disassembly and assembly mechanism includes a plug-in column fixed to the side of the mobile base and a swing rod rotatably hung on the side of the suspension frame, a ball protrusion is provided at one end of the plug-in column away from the mobile base, and the suspension frame is provided with a plug-in groove for the plug-in column to match and pass through;

[0022] The rotation connection point between the rocker member and the suspension frame is located at the top of the rocker member, and a counterweight block is fixed to the bottom of the rocker member; a clamping groove is partially provided on the outer peripheral surface of the plug-in column, and when the plug-in column enters the plug-in groove, the ball protrusion abuts against the rocker member and forces the rocker member to swing outward; when the clamping groove and the rocker member are in the same vertical plane, the rocker member naturally rotates to the inside of the clamping groove due to its own gravity.

[0023] By adopting the above technical solution, by inserting the plug-in column of the base mechanism into the plug-in slot of the suspension frame, the ball protrusion at the end of the plug-in column can first abut against the rocker member and force the rocker member to deflect outward when passing through the plug-in slot; then the plug-in column continues to enter the plug-in slot, and when the clamping slot of the plug-in column is located at a position directly opposite to the rocker member, the rocker member can naturally reset under its own gravity and automatically enter the inside of the clamping slot, thereby limiting the plug-in column from retreating out of the plug-in slot, so as to ensure a stable connection between the base mechanism and the suspension frame. After the lifting action is completed, the base mechanism can be easily removed from the suspension frame by manually moving the rocker member to disengage it from the clamping slot, which has the advantage of convenient disassembly and assembly.

[0024] Optionally, the suspension frame is fixedly provided with a side mold frame, and the side mold frame is rotatably installed with a rotating base, and the rotating base is arranged opposite to the plug-in slot; a plurality of limit members are arranged on the outer peripheral edge of the rotating base close to the plug-in slot, and the ball protrusion is provided with a limit groove matched with the limit member, and when the swing arm member enters the inside of the clamping slot, the limit member is matched and inserted in the limit groove;

[0025] A peripheral gear is provided on the side of the rotating base away from the plug-in slot, and a rotating motor is fixed to the suspension frame. The output end of the rotating motor is fixedly connected to a transmission gear, and the transmission gear and the peripheral gear are meshed with each other for transmission. In addition, the mounting base is rotatably connected to the suspension frame and fixedly connected to the rotating base. The suspension frame is provided with an avoidance groove for the adjustment base to rotate around.

[0026] By adopting the above-mentioned technical scheme, during the specific lifting process, the ALC wall panel can be placed horizontally to lower the center of gravity of the ALC wall panel and reduce the shaking of the ALC wall panel during the lifting process; when the plug-in column is inserted into the plug-in groove and the rocker member automatically enters the clamping groove, the various limit members of the rotating base match and enter the interior of the various limit members of the ball protrusion to achieve circumferential linkage between the rotating base and the plug-in column. At this time, the rotating motor is controlled to operate to drive the transmission gear to rotate, and the meshing transmission between the transmission gear and the outer peripheral gear can make the rotating base rotate, thereby driving the base mechanism and the top seat mechanism driving mechanism to rotate together, and the ALC wall panel can be flipped to a vertical state, so that the ALC wall panel can be smoothly inserted into the preset steel bars at the construction site to complete the lifting operation of the ALC wall panel.

[0027] Optionally, the first adjustment component includes a rotating column, a positioning sleeve fixed to the rotating column, and a hand-turned handle fixed to the end of the rotating column, wherein one of the L-shaped blocks is provided with a through hole, the rotating column is passed through the through hole, and the positioning sleeve and the hand-turned handle are respectively abutted against two opposite sides of the L-shaped block; the other L-shaped block is provided with a threaded groove, and the end of the rotating column away from the hand-turned handle has a threaded portion threadedly connected to the threaded groove.

[0028] By adopting the above-mentioned technical solution, by making the positioning sleeve and the hand-screw handle respectively abut against the two opposite sides of the L-shaped stopper, the L-shaped stopper can be rotated along with the rotating column rod, and then when the hand-screw handle is rotated to make the threaded part move in the spiral groove, the distance between the two groups of top seat components can be smoothly adjusted to adapt to the lifting operation of ALC wall panels of different thicknesses.

[0029] Optionally, the base unit further includes a traveling wheel set arranged at the bottom of the base mechanism.

[0030] By adopting the above-mentioned technical solution, by arranging a walking wheel group at the bottom of the base mechanism, after the ALC wall panel is placed in the placement groove of the base mechanism, the construction personnel can easily push the base mechanism to move on the flat ground, so as to facilitate the short-distance transportation of the ALC wall panel, which can reduce the hoisting distance and improve the efficiency of the hoisting operation.

[0031] Optionally, elastic pads are bonded to the inner walls of the placement groove and the inner walls of the receiving groove.

[0032] By adopting the above-mentioned technical solution, during the lifting operation, the two side edges of the ALC wall panel are respectively located in the placement groove and the receiving groove, and can lean against the elastic soft pads on the inner wall, thereby reducing the wear between the ALC wall panel and the inner wall of the groove, so as to ensure the aesthetics and usability of the ALC wall panel.

[0033] Optionally, the number of the limiting units and the number of the base units are both set to two groups, and the two groups of limiting units and the two groups of base units are symmetrically arranged on two opposite sides of the suspension frame.

[0034] By adopting the above technical solution, by symmetrically arranging two groups of limit units and two groups of base units on two opposite sides of the suspension frame, two ALC wall panels can be hoisted at one time, which greatly improves the hoisting operation efficiency and is conducive to shortening the construction period of the entire project.

The inner wall of the placement groove 514 is bonded with an elastic cushion 515. The elastic cushion 515 in this embodiment uses a polyurethane cushion, which can reduce the friction damage between the ALC wall panel and the inner wall of the placement groove 514 after the ALC wall panel is placed, so that the ALC wall panel maintains good aesthetics and usability.
