Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a lifting equipment for composite plates. Background Technology

[0002] Composite slabs are mass-produced in factories, requiring only the installation and pouring of the surface layer on-site. This reduces the time spent on traditional formwork and reinforcement, significantly increasing construction speed. On-site wet work is mainly concentrated on the pouring of the cast-in-place layer, avoiding the cumbersome processes of large-area formwork erection and concrete curing, and reducing on-site construction intensity.

[0003] Due to the large area and heavy weight of composite slabs, they require movement using lifting equipment during loading, transportation, and construction. Existing composite slab lifting equipment has fixed dimensions and is not adjusted according to the slab size. Because composite slabs vary in size, multiple specifications of lifting equipment are typically purchased for different slab sizes. This not only increases costs but also requires more space to store the lifting equipment.

[0004] To address the problems in existing technologies, we propose a composite slab lifting device. Utility Model Content

[0005] This utility model addresses the problems in the prior art by providing a composite slab lifting tool, which is achieved through the following technical solution: A composite slab lifting device includes a hanger, a chain, and a hook. The hanger includes a fixed rod, a movable rod, and a fixing assembly. Two sets of fixed rods and movable rods are provided. The two fixed rods are respectively located at one opposite corner of the hanger, and the two movable rods are respectively located at the other opposite corner. The fixed rod has a through sliding cavity. Sliding rods are fixedly connected to both ends of the movable rod and slidably connected to the sliding cavity. The sliding rods are fixed to the fixed rods via the fixing assembly. Lifting lugs are fixedly connected to the corners of the upper surfaces of the fixed rods and movable rods. The chain and hook are located at the corners of the lower surfaces of the fixed rods and movable rods.

[0006] The present invention is further configured such that: the fixing component includes a locking rod and a locking nut, the locking rod is fixedly connected to two parallel side walls of the sliding rod, and a sliding groove is provided on the side wall corresponding to the fixing rod and the locking rod for the locking rod to pass through. The sliding groove communicates with the sliding cavity, the locking rod passes through the sliding groove and is threadedly connected to the locking nut, and the locking nut abuts against the side wall of the fixing rod.

[0007] The present invention is further configured such that: the inner wall of the sliding cavity and the sliding rod are respectively provided with rolling components, the rolling components on the sliding rod are provided at the end of the sliding rod away from the moving rod, and the rolling components on the sliding cavity are respectively provided at both ends of the sliding cavity.

[0009] The present invention is further configured such that: the lower end faces of the fixed rod and the movable rod are respectively fixedly connected with support legs.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0014] like Figure 1-4As shown, this utility model discloses a composite plate lifting device, including a hanger 1, a chain 2, and a hook 3. The hanger 1 includes a fixed rod 11, a movable rod 12, and a fixing component 4. The fixed rod 11 and the movable rod 12 are respectively provided in two sets. The two fixed rods 11 are respectively located at one of the opposite corners of the hanger 1, and the two movable rods 12 are respectively located at the other opposite corner of the hanger 1. The fixed rod 11 has a through sliding cavity 111. The two ends of the movable rod 12 are respectively fixedly connected to sliding rods 121, which are slidably connected in the sliding cavity 111. The sliding rods 121 are fixed to the fixed rod 11 by the fixing component 4. The upper end face corners of the fixed rod 11 and the movable rod 12 are respectively fixedly connected to lifting lugs 5. The chain 2 and the hook 3 are provided at the lower end face corners of the fixed rod 11 and the movable rod 12. The movable rod 12 moves relative to the fixed rod 11 via the sliding rod 121. After moving to a suitable position, it is fixed by the fixing component 4, thereby ensuring the overall stability of the hanger 1. By adjusting the position between the movable rod 12 and the fixed rod 11, and adjusting the distance between the lifting chains 2 (hooks 3), the hanger 1 can be adapted to composite boards of different sizes, improving the adaptability of the hanger 1. This not only reduces the cost of the hanger 1 but also reduces the floor space occupied by the hanger 1.

[0015] The fixing assembly 4 includes a locking rod 41 and a locking nut 42. The locking rod 41 is fixedly connected to two parallel side walls of the sliding rod 121. The side walls of the fixing rod 11 and the locking rod 41 are provided with sliding grooves 112 for the locking rod 41 to pass through. The sliding grooves 112 communicate with the sliding cavity 111. The locking rod 41 passes through the sliding grooves 112 and is threadedly connected to the locking nut 42. The locking nut 42 abuts against the side wall of the fixing rod 11. When the sliding rod 121 moves to a suitable position, the locking nut 42 is tightened, so that the locking nut 42 abuts tightly against the side wall of the fixing rod 11, thereby fixing the position of the sliding rod 121.

[0016] Rolling components 6 are respectively provided on the inner wall of the sliding cavity 111 and on the sliding rod 121. The rolling components 6 on the sliding rod 121 are located at the end of the sliding rod 121 away from the moving rod 12, and the rolling components 6 on the sliding cavity 111 are respectively located at both ends of the sliding cavity 111. The rolling components 6 include a support shaft 61 and rollers 62. Grooves 7 are provided on the side walls of both the sliding rod 121 and the sliding cavity 111. The support shaft 61 is fixedly connected between the two parallel side walls of the groove 7. The rollers 62 are rotatably connected to the support shaft 61. The rollers 62 on the sliding rod 121 protrude from the upper and lower end faces of the sliding rod 121 and contact the top and bottom walls of the sliding cavity 111 respectively. The rollers 62 on the sliding cavity 111 protrude from the top and bottom walls of the sliding cavity 111 and contact the upper and lower end faces of the sliding rod 121 respectively. The rolling assembly 6 transforms the sliding friction between the sliding rod 121 and the side wall of the sliding cavity 111 into rolling friction, which greatly reduces the friction between the sliding rod 121 and the side wall of the sliding cavity 111, making it easier for workers to move the sliding rod 121.

[0017] The lower ends of the fixed rod 11 and the movable rod 12 are respectively fixedly connected with support legs 8. The support legs 8 can prevent the entire weight of the hanger 1 from pressing on the chain 2 or the hook 3 when the hanger 1 is not in use, which would cause the moving parts of the chain 2 and the hook 3 to deform and affect normal use.
