Description
Technical Field
[0001] This application relates to the field of hoisting of laminated slabs, and particularly to an auxiliary positioning device for hoisting precast laminated slabs. Background Art
[0002] A laminated slab is an assembled integral floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. The laminated floor slab has good integrity, and the upper and lower surfaces of the slab are flat, which is convenient for the decoration of the finishing layer. It is suitable for high-rise buildings and large-span buildings with high requirements for overall stiffness.
[0003] When installing a laminated slab, a hoisting device is required for hoisting. During hoisting, a steel wire rope needs to be bound to an appropriate position on the slab body, and then the steel wire rope is hoisted on the lifting tool. However, due to long-term wear at the connection between the steel wire rope and the slab body, the connection part may become unstable. In severe cases, the laminated slab may even tilt. Therefore, we propose an auxiliary positioning device for hoisting precast laminated slabs to solve the above-mentioned deficiencies. Utility Model Content
[0004] In order to solve the existing technical problems, this application provides an auxiliary positioning device for hoisting precast laminated slabs.
[0005] An auxiliary positioning device for hoisting precast laminated slabs provided by this application adopts the following technical scheme: An auxiliary positioning device for hoisting precast laminated slabs includes a positioning plate arranged at the bottom of a crane. The crane is connected to a pulley seat through a transmission rope. A shaft rod is rotatably connected to the bottom of the inner cavity of the pulley seat. A connecting plate is fixedly connected to the bottom of the shaft rod. On both sides of the surface of the connecting plate, a first hook is fixedly connected. A steel wire rope body is hung on the surface of the first hook. One end of the steel wire rope body away from the first hook is hung on a second hook. A threaded bolt is welded to the bottom of the second hook. The bottom of the threaded bolt penetrates through the positioning plate and extends to the bottom of the positioning plate. A limiting insertion hole for the threaded bolt to penetrate and slide is formed on the surface of the positioning plate. An upper limiting nut and a lower limiting nut are respectively threadedly connected to the top and bottom of the threaded bolt surface. The surfaces of the upper limiting nut and the lower limiting nut are closely attached to the connection part of the positioning plate.
[0006] By adopting the above technical solution, by placing both sides of the laminated plate between the positioning plates, and then, according to the situation, inserting the threaded bolts into the limiting jacks closest to the laminated plate, so that the threaded bolts penetrate through the end faces of the upper and lower positioning plates, and threadedly connecting the upper limiting nut to the upper surface of the thread of the threaded bolt, so that the upper limiting nut fits with the positioning plate, and threadedly connecting the lower limiting nut to the lower surface of the thread of the threaded bolt, so that the lower limiting nut fits tightly with the positioning plate, making the connection more stable, replacing the way of directly binding the steel wire rope to the plate body, thus avoiding the situation of breakage and deviation. Since the threaded bolt and the hook two are welded, under the drive of the crane, and by means of the pulley seat, the shaft rod is lifted, and finally, under the connection of the connecting plate, the hook one and the steel wire rope body, the positioning plate is lifted.
[0007] Preferably, the upper and lower positioning plates are symmetrically arranged, and a limiting plate is fixedly connected to the outer end face of the positioning plate, and an L-shaped design is formed between the limiting plate and the positioning plate.
[0008] By adopting the above technical solution, by arranging the limiting plate and with an L-shaped design between the limiting plate and the positioning plate, the two ends of the plate can be limited, the contact area between the two ends and the positioning plate can be increased, and the plate can be prevented from falling off from the two ends.
[0009] Preferably, the opposite end faces of the upper and lower positioning plates are designed as friction surfaces.
[0010] By adopting the above technical solution, by designing the opposite end faces of the upper and lower positioning plates as friction surfaces, through the action of friction force, the connection between the positioning plate and the laminated plate is made more stable, and the laminated plate is not easily detached during hoisting.
[0011] Preferably, one end of the steel wire rope body close to the hook one and the hook two is arranged by forming a loop, and the surfaces of the hook one and the hook two are both hung and slid with the formed loop.
[0012] By adopting the above technical solution, it is convenient for the steel wire rope body to be hung with the hook one and the hook two.
[0013] Preferably, the number of the limiting jacks is multiple, and the multiple limiting jacks are evenly arranged on the surface of the positioning plate.
[0014] Preferably, the two threaded bolts are located outside the peripheral plate body, the distance between the threaded bolts is greater than the width distance of the plate body. When placing the plate body, the threaded bolts penetrate through the limiting jacks close to the end face of the plate body, and are threadedly tightened by the upper limiting nut and the lower limiting nut.
[0015] By adopting the above technical solution, by setting the number of the limiting jacks to be multiple, the specific position where the threaded bolt is inserted into the limiting jack can be adjusted according to the width of the plate, so that the upper and lower contact surfaces are more stable.
[0016] In summary, the present application includes at least one of the following beneficial technical effects:

Then, according to the situation, the threaded bolt is inserted into the limiting jack closest to the laminated board, so that the threaded bolt penetrates through the end faces of the upper and lower positioning plates. The upper limiting nut is threadedly connected to the upper surface of the threaded bolt thread, so that the upper limiting nut fits with the positioning plate. The lower limiting nut is threadedly connected to the lower surface of the threaded bolt thread, so that the lower limiting nut fits tightly with the positioning plate, making the connection more stable, replacing the way of directly binding the steel wire rope to the plate body, thus avoiding the situation of breakage and deviation. Since the threaded bolt and the hook two are welded, under the drive of the crane, the shaft rod is lifted through the pulley seat, and finally, through the connection of the connecting plate, the hook one and the steel wire rope body, the positioning plate is lifted.
