Description

Technical Field

[0001] This utility model relates to the field of hoisting tools, and in particular to a hoisting device for the construction of prefabricated composite slabs. Background Technology

[0002] During the assembly and construction of composite slabs, hoisting equipment for composite slab construction is required. Existing hoisting equipment for composite slab construction generally has advantages such as fast hoisting speed, large hoisting weight, simple operation, high working stability, and long service life, which can meet the hoisting needs during the assembly and construction of composite slabs.

[0003] Existing hoisting equipment typically uses multiple hooks to directly attach the four corner steel bars of the composite slab. During hoisting, the uneven force at the four corners can easily cause the composite slab to crack. Furthermore, since the hooks are directly attached to the steel bars, they can easily come loose due to wind and vibration during hoisting, posing a certain safety hazard. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: existing hoisting equipment usually uses multiple hooks to directly hang the four corner steel bars of the composite slab. During hoisting, the composite slab is prone to cracking due to the unbalanced force at the four corners. Secondly, the hooks are directly hung on the steel bars. During hoisting, the hooks are prone to disengagement due to wind and vibration, which poses certain safety hazards. Therefore, a hoisting device for prefabricated composite slab construction is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hoisting device for the construction of prefabricated composite slabs includes a base plate and a hoisting plate, wherein the hoisting plate is disposed above the base plate;

[0007] An adjustment mechanism is provided on the base plate. The adjustment mechanism includes an adjustment cylinder, a pressing plate, a sliding rod, a connecting chain, a hook, and a fixing cylinder. Multiple adjustment cylinders are fixedly connected to the four corners of the lower end face of the base plate. Multiple pressing plates are slidably connected to the inner sidewalls of the adjustment cylinders. Multiple sliding rods are fixedly connected to the inner sidewalls of the pressing plates. Multiple connecting chains are fixedly connected to the lower end face of the sliding rods. Multiple hooks are fixedly connected to the end of the connecting chain away from the sliding rod. Multiple fixing cylinders are fixedly connected to the inner sidewalls of the hooks.

[0008] Preferably, the adjusting mechanism further includes a push plate and a sealing rod. The push plate is slidably connected to the inner wall of the fixed cylinder, and the sealing rod is fixedly connected to the side wall of the push plate. The sealing rod is slidably connected to the fixed cylinder.

[0009] Preferably, buffer cylinders are fixedly connected to the four corners of the upper surface of the base plate, the slide rod is slidably connected to the side wall of the buffer cylinder, and a buffer plate is fixedly connected to the end of the slide rod away from the extrusion plate. The buffer plate has multiple through holes in a ring shape.

[0010] Preferably, a plurality of steel wire ropes are fixedly connected between the hanging plate and the base plate, and a hanging ring is fixedly connected to the upper surface of the hanging plate.

[0011] Preferably, a laser emitter is fixedly connected to the lower end face of the base plate, and a conduit is fixedly connected between the buffer cylinder and the fixed cylinder.

[0012] Preferably, a buffer spring is fixedly connected between the buffer plate and the buffer cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By coordinating the lifting platform and the laser emitter, the lifting position is adjusted to the center of the composite plate before hoisting, so that the force on the composite plate is evenly distributed. With the help of the buffer cylinder and buffer spring, the impact force on the composite plate during hoisting is greatly reduced, and the composite plate is prevented from cracking during hoisting.

[0015] 2. By cooperating with the adjusting cylinder and the fixed cylinder, the weight of the composite plate itself is used during hoisting to pull the hook and the sliding rod, thereby locking the sealing rod to the hook. This prevents the composite plate from swaying or tilting due to wind or vibration during hoisting, which could cause the hook to fall off and prevent accidents caused by the composite plate falling off. It is very safe and reliable. It automatically locks when hoisting and automatically unlocks when the composite plate is lowered. It is very simple and easy to operate. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A hoisting device for prefabricated composite slab construction includes a base plate 1 and a hoisting plate 2. The hoisting plate 2 is positioned above the base plate 1. A laser emitter 15 (a simple laser pointer will suffice) is fixedly connected to the lower end face of the base plate 1. The laser emitter 15 can emit laser light for positioning and marking. Multiple steel wire ropes 13 are fixedly connected between the hoisting plate 2 and the base plate 1. A hanging ring 14 is fixedly connected to the upper end face of the hoisting plate 2.

[0024] An adjustment mechanism is provided on the base plate 1. The adjustment mechanism includes an adjustment cylinder 3, a pressing plate 4, a sliding rod 5, a connecting chain 6, a hook 7, and a fixed cylinder 8. Multiple adjustment cylinders 3 are fixedly connected to the four corners of the lower end face of the base plate 1. Multiple pressing plates 4 are sealed and slidably connected to the inner side wall of the adjustment cylinder 3. Multiple sliding rods 5 are fixedly connected to the inner side wall of the pressing plate 4. The sliding rods 5 and the adjustment cylinder 3 are not sealed. Multiple connecting chains 6 are fixedly connected to the lower end face of the sliding rod 5. Multiple hooks 7 are fixedly connected to the end of the connecting chain 6 away from the sliding rod 5. Multiple fixed cylinders 8 are fixedly connected to the inner side wall of the hooks 7. The adjustment mechanism also includes a push plate 9 and a sealing rod 10. The push plate 9 is sealed and slidably connected to the inner side wall of the fixed cylinder 8. The sealing rod 10 is fixedly connected to the side wall of the push plate 9. The sealing rod 10 is slidably connected to the fixed cylinder 8. The sealing rod 10 and the fixed cylinder 8 are not sealed. Hydraulic oil is stored in both the fixed cylinder 8 and the adjustment cylinder 3.

[0025] A buffer cylinder 11 is fixedly connected to each of the four corners of the upper end face of the base plate 1. The buffer cylinder 11 stores hydraulic oil. A conduit 16 is fixedly connected between the buffer cylinder 11 and the fixed cylinder 8. The slide rod 5 is slidably connected to the side wall of the buffer cylinder 11. A buffer plate 12 is fixedly connected to the end of the slide rod 5 away from the extrusion plate 4. Multiple through holes are opened in a ring on the buffer plate 12, through which hydraulic oil can pass. A buffer spring 17 is fixedly connected between the buffer plate 12 and the buffer cylinder 11.

[0026] In this utility model, when in use, the lower end of the crane is first connected to the hanging ring 14, and then the four hooks 7 are respectively hung on the steel bars at the four corners of the composite plate. The crane is first slightly raised, and the hanging ring 14 and the hanging plate 2 are raised. The hanging plate 2 lifts the bottom plate 1 through the wire rope 13. At this time, the connecting chain 6 is still in a slack state, and the composite plate is not under stress. Then, the worker aligns the light spot emitted by the laser emitter 15 with the center of the composite plate, guides the crane to align the center of the bottom plate 1 with the center of the composite plate, and then lifts it vertically upward. At this time, the distances from the four adjusting cylinders 3 to the four corners of the composite plate are nearly equal, and the four corners of the composite plate are evenly stressed and not easy to break. When lifting, the hooks 7 drive the sliding rod 5 to move down, and the sliding rod 5 drives the buffer plate 12 to move down. The buffer plate 12 moves in the buffer cylinder 11. The hydraulic oil in the buffer cylinder 11 passes through the small hole on the buffer plate 12 and compresses the buffer spring 17 to buffer the force when the composite plate is pulled up, so as to prevent it from breaking when lifted rapidly.

[0027] The sliding rod 5 moves down, causing the extrusion plate 4 to move down as well, which in turn extrudes the hydraulic oil in the regulating cylinder 3. The hydraulic oil then flows through the guide tube 16 into the fixed cylinder 8, pushing the push plate 9 and the sealing rod 10 to move. The sealing rod 10 moves forward and locks the notch of the hook 7, preventing the stacked plate from swaying or tilting due to wind or vibration during hoisting, thus preventing the hook 7 from falling off and causing a safety accident. After being hoisted to the destination, the stacked plate is placed on the ground, and the tension of the stacked plate on the hook 7 disappears. Under the elastic force of the buffer spring 17, the buffer plate 12 drives the sliding rod 5 and the extrusion plate 4 to reset, and the hydraulic oil in the fixed cylinder 8 flows back into the regulating cylinder 3. The sealing rod 10 no longer locks the hook 7, and the worker can easily remove the hook 7. The hook 7 is locked by the weight of the stacked plate itself, which is very safe and reliable. It automatically locks when hoisting and automatically unlocks when the stacked plate is lowered, making it very simple and easy to operate.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
