Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated stair production, and more specifically, to a prefabricated stair production hoisting device. Background Art

[0002] Prefabricated stairs are industrially manufactured in factories. The prefabrication factory will pour concrete into the corresponding staircase mold according to the design drawings, and transport it to the predetermined location on the construction site for installation after it hardens. Compared with traditional stairs, prefabricated stairs do not require complex frames, are not affected by weather, and do not require a lot of time to mix and pour concrete. In addition, the hollow characteristics of prefabricated stairs also make them lighter. These factors combined make the installation speed of prefabricated stairs much faster than traditional stairs.

[0003] In the production process of prefabricated stairs, lifting is an important step. This is because prefabricated stairs are usually produced in factories according to certain standards and specifications. They are made into individual components or modules, and then transported to the construction site for assembly by lifting. The main purpose of lifting is to facilitate the handling and installation of these staircase components, because these components are often large, heavy, and may have special shapes. Direct handling may be very difficult and may even cause damage.

[0004] When existing prefabricated stairs are produced, threaded holes are reserved in advance on the side of the stairs. After production is completed, bolts are threadedly connected through the threaded holes, and then the bolts are connected through the hoist to complete the lifting of the stairs. However, the bolts need to be rotated many times to connect the threaded holes, and sometimes tools are needed to thread the bolts into the threaded holes, which delays the staff's time and reduces the staff's work efficiency.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a prefabricated stair production and lifting device. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model aims to provide a prefabricated stair production and lifting device.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: the prefabricated stair production and hoisting device comprises a staircase;

[0008] A plug-in mechanism is arranged on one side of the staircase;

[0009] There are two groups of plug-in mechanisms, one group of the plug-in mechanisms includes clamps, there are two groups of clamps, one side of the two groups of clamps are connected to card pieces, one side of the one group of clamps is connected to a sliding rod, one end of the sliding rod passes through the other group of clamps, a spring is sleeved on the outer surface of the sliding rod, four groups of grooves are provided on one side of the stairs, a card slot is provided between the two groups of grooves, the card piece is inserted in the card slot, and the stairs are clamped by the plug-in mechanism, thereby driving the clamp to move, and driving the stairs to move.

[0010] Preferably, a threaded groove is provided at one end of the slide rod, and a nut is threadedly connected to the outer surface of the threaded groove. The nut serves as a limit to prevent the clamp from falling off, and the nut can be rotated to disassemble the clamp, separate the clamp from the slide rod, take out the internal spring, and replace the spring that has been used for a long time.

[0011] Preferably, the other group of clamps slides on the outer surface of the slide rod to facilitate adjustment of the distance between the two groups of clamps.

[0012] Preferably, one end of the four groups of clamps are connected to a lifting rope, the other end of the lifting rope is connected to a sling, and one end of the sling is connected to a crane. The sling is driven by the crane to move, so that the lifting rope is straightened, and then the stairs are driven to move, thereby completing the lifting of the stairs.

[0013] Preferably, when the spring is not under force, the two groups of card parts are close to each other. When the spring is stretched under force, the card part passes through the groove, releasing the force on the spring, and the spring releases its elastic potential energy and contracts, driving the card part to be inserted into the card slot, and the two groups of card parts are close to each other.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. By setting up a plug-in mechanism, force can be applied to the spring so that the spring is stretched. After the card passes through the groove, the force on the spring is released, and the spring releases its elastic potential energy to contract, driving the card to be inserted into the card slot. The two sets of card parts are close to each other, thereby solving the problem that the bolt needs to be rotated many times to connect the threaded hole, and sometimes tools are needed to thread the bolt into the threaded hole, which delays the staff's time and reduces the staff's work efficiency.

[0016] 2. By setting the nut and the thread groove, the nut can be used to limit the position and prevent the clamp from falling off. The nut can be rotated to disassemble the clamp, the clamp can be separated from the slide rod, the spring sleeved on the outside of the slide rod can be taken out, and the spring that has been used for a long time can be replaced.

[0023] like Figure 1 - Figure 4 As shown, the utility model provides a prefabricated stair production and lifting device, comprising a stair 1;

[0024] A plug-in mechanism is arranged on one side of the staircase 1;

[0025] There are two groups of plug-in mechanisms, one group of plug-in mechanisms includes a clamp 4, and the number of clamps 4 is two groups. One side of the two groups of clamps 4 is connected to a clamp 6, one side of one group of clamps 4 is connected to a slide bar 7, one end of the slide bar 7 passes through the other group of clamps 4, and a spring 5 is sleeved on the outer surface of the slide bar 7. Four groups of grooves 10 are opened on one side of the staircase 1, and a clamping groove 11 is opened between the two groups of grooves 10, and the clamping member 6 is inserted in the clamping groove 11;

[0026] Another set of clamps 4 slides on the outer surface of the slide bar 7;

[0029] First, the distance between the two sets of clamps 4 is increased by manual force, so that the spring 5 is stretched by force, and then the clamp 4 is moved through the groove 10 to release the force on the spring 5. The spring 5 releases its elastic potential energy and contracts, thereby driving the clamp 6 to insert into the slot 11. The two sets of clamps 6 in the slot 11 are close to each other, and then the crane is controlled to drive the sling 3 to move upward. After the lifting rope 2 is straightened, the stair 1 is driven to move upward, thereby completing the lifting of the stair 1. There is no need to use bolts to connect the threaded holes, which speeds up the work efficiency of the staff;

[0030] like Figure 2 and Figure 3As shown, a thread groove 9 is formed at one end of the slide rod 7, and a nut 8 is threadedly connected to the outer surface of the thread groove 9;

[0031] The nut 8 is provided to play a limiting role to prevent the clamp 4 from falling off, and the nut 8 can be rotated to disassemble the nut 8 and the slide rod 7, so that the clamp 4 is separated from the slide rod 7, and the spring 5 sleeved on the outside of the slide rod 7 is taken out, and the spring 5 that has been used for a long time is replaced to improve the working stability of the spring 5.
