Description

Technical Field

[0001] This utility model application belongs to the field of prefabricated component hoisting technology, specifically relating to a simple hoisting device. Background Technology

[0002] In the construction industry, precast concrete components are increasingly being used in building projects. Therefore, the demand for precast components is also growing. Among these, large precast components exceeding 5 meters in height require specialized brackets as bases during normal hoisting.

[0003] When producing a large number of large precast components at once, there may be a shortage of dedicated brackets for placing these components in a short period of time. This results in a large number of precast components being unable to be properly hoisted and transported, which takes up a lot of space in the production area. This not only wastes production space but also indirectly increases the workload of staff and even seriously hinders the production work of on-site personnel, undoubtedly reducing construction efficiency and seriously affecting the progress of the work.

[0004] Therefore, there is an urgent need to design a hoisting device that can be used for the placement and hoisting of precast components over 5 meters in height, eliminating the reliance on existing special brackets and allowing the precast components to be hoisted at any time, avoiding the occupation of production site space. This will achieve the technical effects of reducing the workload of construction workers, improving construction efficiency, accelerating construction progress, and ensuring the smooth progress of production and construction, ultimately enhancing the company's market competitiveness, improving the company's economic benefits, and promoting the company's healthy development.

[0006] To achieve the above objectives, this utility model provides a simple hoisting device for hoisting precast components. The device includes: a pad, the upper surface of which is used to place and support the precast component; at least three support rails, spaced apart along the length of the precast component at the bottom of the pad, the length of each support rail being greater than the width of the precast component, used to support the pad and the precast component, and each support rail having a through track inside; and slings, which are inserted through the support rails in the middle and located outside the support rails at both ends and connected to a hoisting device.

[0007] Furthermore, the pads are square wooden blocks, and there are several square wooden blocks, which are spaced apart on each supporting guide rail. At least two square wooden blocks are set on each supporting guide rail, and each square wooden block is arranged perpendicularly to the supporting guide rail.

[0008] Furthermore, the pad is a long strip of wood, and there are several long strips of wood. The long strips of wood are laid on each of the spaced-apart support rails. At least two long strips of wood are placed at intervals on each support rail, and each long strip of wood is arranged perpendicularly to the support rail.

[0009] Furthermore, the supporting guide rail is made of channel steel and is set at the bottom of the pad with its opening facing downwards; during lifting, the lifting strap passes through the channel steel and abuts against the lower end face of the web of the channel steel.

[0010] Furthermore, the supporting guide rail is a square tube; during lifting, the lifting strap passes through the square tube and abuts against the inner end face of the square tube.

[0011] Furthermore, the supporting guide rail is made of steel profile and is set in an H-shape at the bottom of the pad; during lifting, the lifting strap passes under the web of the steel profile and abuts against the lower end face of the web.

[0012] Furthermore, the supporting guide rail is made of galvanized steel.

[0013] Furthermore, protective devices are provided at both ends of the supporting guide rail, with the protective devices located between the supporting guide rail and the sling; the upper end of the protective device is used to abut against the supporting guide rail, and the lower end of the protective device is used to abut against the sling.

[0014] Furthermore, the protective gear is an inverted U-shaped pad, with each protective gear having a portion inserted into the end of the supporting guide rail and another portion exposed outside, and a limiting part is made on the exposed portion of the protective gear.

[0015] Furthermore, the straps are made of nylon.

[0039] The specific embodiments of this utility model application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this disclosure.

[0040] In the technical solutions disclosed in this utility model application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to those defined based on the drawing direction of the corresponding figures, while "inner" and "outer" refer to those inside and outside relative to the outline of the component or structure itself. Furthermore, in the description of the accompanying drawings, the same reference numerals in different figures denote the same elements.

[0041] According to this utility model application, a simple hoisting device is provided for hoisting prefabricated component 1, such as... Figures 1 to 7 As shown, it includes:

[0042] Pad 2, the upper end of pad 2 is used to place and support prefabricated component 1;

[0043] There are at least three support rails 3, which are spaced apart at the bottom of the pad 2 along the length of the precast component 1. The length of the support rail 3 is greater than the width of the precast component 1. They are used to support the pad 2 and the precast component 1, and the support rail 3 has a through track inside.

[0044] The sling 5 is used to pass through the middle of the support rail 3, and its two ends are located outside the support rail 3 and connected to the lifting device 6.

[0045] In the above technical solution, by setting up a pad 2 to replace the special bracket in the prior art, the prefabricated component 1 is placed on the pad 2 for hoisting, thus solving the problem of insufficient special brackets when a large number of prefabricated components 1 are produced. At the same time, support rails 3 are set at intervals at the bottom of the pad 2, and the length of the support rails 3 is greater than the width of the prefabricated component 1, to ensure that the bottom pad 2 is evenly stressed on the same bottom surface during hoisting, ensuring that the prefabricated component 1 will not tilt during hoisting, thus achieving the purpose of safe hoisting. In addition, a through track is made in the support rails 3, which operators can use to quickly thread the sling 5 and connect the sling 5 to the hoisting device 6 (the hoisting device 6 can be a standardized steel spreader, etc.), so that the hoisting work can be completed smoothly and efficiently.

[0046] It is worth mentioning that in practical use, such as Figure 7 As shown, this simple hoisting device is used in a similar manner to a special bracket. It can arrange and hoist multiple prefabricated components 1 from bottom to top, with adjacent prefabricated components 1 separated by pads 2.

[0047] In this embodiment, such as Figure 3 , Figure 4 As shown, the pad 2 is a square wooden block 201, and there are several square wooden blocks 201, which are spaced apart on each supporting guide rail 3. At least two square wooden blocks 201 are set on each supporting guide rail 3, and each square wooden block 201 is arranged perpendicularly and alternately with the supporting guide rail 3. In specific operation, the precast component 1 is usually divided into: ① the width of the precast component 1 is within 1.5 meters, in which case two square wooden blocks 201 are set on each supporting guide rail 3; ② the width of the precast component 1 is greater than 1.5 meters, in which case three square wooden blocks 201 are set on each supporting guide rail 3.

[0048] In some implementations, such as Figure 5 , Figure 6As shown, the pad 2 is a long strip of wood 202, and there are several long strips of wood 202. The long strips of wood 202 are laid on the support rails 3 at intervals. That is, the two ends and the middle part of each long strip of wood 202 are laid on each support rail 3 respectively. At least two long strips of wood 202 are placed at intervals on each support rail 3, and each long strip of wood 202 is arranged perpendicularly and alternately with the support rail 3. In specific operation, the precast component 1 is also divided into: ① the width of the precast component 1 is less than 1.5 meters, in which case two long strips of wood 202 are set on each support rail 3; ② the width of the precast component 1 is greater than 1.5 meters, in which case three long strips of wood 202 are set on each support rail 3.

[0049] Regarding the selection and use of the support rail 3, some specific implementation methods include:

[0050] Example (1)

[0051] like Figure 8 As shown, the supporting guide rail 3 is a channel steel, with its opening facing downwards at the bottom of the pad 2; during lifting, the lifting strap 5 passes through the channel steel and abuts against the lower end face of the web of the channel steel.

[0052] Example (2)

[0053] like Figure 9 As shown, the supporting guide rail 3 is a square tube; during lifting, the lifting strap 5 passes through the square tube and abuts against the inner end face of the square tube.

[0054] Example (3)

[0055] like Figure 10 As shown, the supporting guide rail 3 is a steel section, which is set in an H shape at the bottom of the pad 2; during lifting, the lifting strap 5 passes under the web of the steel section and abuts against the lower end face of the web.

[0056] Preferably, in the selection of the material of the supporting guide rail 3, galvanized steel can be selected regardless of the shape of the steel used, so as to extend the service life of the device.

[0057] In other implementations, such as Figure 1 As shown, guards 4 are respectively provided at both ends of the supporting guide rail 3, and the guards 4 are located between the supporting guide rail 3 and the sling 5; the upper end of the guard 4 is used to abut against the supporting guide rail 3, and the lower end of the guard 4 is used to abut against the sling 5. Specifically, as shown... Figure 11As shown, the protective device 4 is an inverted U-shaped pad. Each protective device 4 has a portion inserted into the end of the supporting guide rail 3 and another portion exposed outside. The exposed portion of the protective device 4 has a limiting part 401, which is used to lock into the port of the supporting guide rail 3 to prevent the entire protective device 4 from being completely embedded in the supporting guide rail 3 during use. Preferably, the protective device 4 can be made of materials such as rubber or sponge.

[0058] In other embodiments, the sling 5 is made of nylon.
