The prefabricated stair slab is provided with a sliding groove, which is arranged along the length of the first inclined surface of the prefabricated stair slab. The prefabricated steps are connected to a sliding member, and the prefabricated steps are slidably engaged with the sliding groove of the prefabricated stair slab through the sliding member. Each prefabricated step is arranged sequentially along the first inclined surface of the prefabricated stair slab. This prefabricated staircase can reduce the weight of the prefabricated staircase, meet the lifting capacity requirements of conventional tower cranes in China, and reduce the application limitations caused by the excessive weight of the prefabricated staircase.

[0003] Based on the aforementioned documents, existing prefabricated stairs are mostly installed by hoisting. However, during hoisting, prefabricated stairs are prone to swaying and have poor stability, which may lead to the stairs tipping over. Furthermore, when moving to the installation site, existing hoisting devices can only adjust the installation position of prefabricated stairs by a large range, making it impossible to make small-angle fine adjustments, which in turn affects the installation quality of the prefabricated stairs. Therefore, this utility model provides an installation adjustment device for prefabricated stairs. Utility Model Content

[0014] Beneficial effects

[0015] This utility model provides an installation and adjustment device for prefabricated stairs. Compared with the prior art, it has the following advantages:

[0016] 1. The installation and adjustment device for this prefabricated staircase uses a drive motor to rotate a drive screw. The rotation of the drive screw causes the sliding plate to slide, which in turn causes the transmission block to slide on the inner surface of the inclined slide groove. This causes the transmission blocks, transmission rods, and folded plates on both sides to slide synchronously to opposite sides. The sliding of the folded plates causes the adjustment plates on both sides to move synchronously. The adjustment plates on both sides clamp the prefabricated staircase body on both sides. With the adjustment mechanism, the distance between the adjustment plates on both sides can be flexibly adjusted by the drive motor. In addition, multiple sets of adjustment plates on both sides can clamp and fix prefabricated staircase bodies of different sizes, so that the prefabricated staircase body remains stable during subsequent installation and movement, thus improving the installation quality of the prefabricated staircase body.

[0017] 2. The installation and adjustment device for this prefabricated staircase, through the installation of a hoisting mechanism, uses two sets of control motors to enable the steel cables and hooks on both sides to simultaneously lift the prefabricated staircase body. Driven by a control motor on one side, the balance of the prefabricated staircase body after hoisting can be better adjusted, reducing the possibility of the prefabricated staircase body tipping over. Through the installation of a rotating component, driven by a rotating motor, the rotation angle of the prefabricated staircase body can be finely adjusted, thereby facilitating subsequent installation operations.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] An installation and adjustment device for a prefabricated staircase includes a crane body 1 and a staircase body 2. A support arm 3 is rotatably connected to the top of the crane body 1, and a bearing plate 4 is fixedly connected to one end of the support arm 3. A hoisting mechanism 5 is provided at the top of the bearing plate 4, and an adjustment mechanism 6 is provided at the bottom of the bearing plate 4. The adjustment mechanism 6 includes:

[0027] The adjusting assembly 61 includes a concave plate 611 installed at the bottom of the support plate 4. A support shaft 612 is rotatably connected inside the concave plate 611. The top end of the support shaft 612 is fixedly connected to the bottom of the support plate 4. An equipment box 613 is rotatably connected to the bottom end of the support shaft 612. A sliding plate 614 is slidably connected inside the equipment box 613. An inclined groove 615 is provided on the top of the sliding plate 614. The inner surface of the inclined groove 615 causes the adjusting plate 616 to slide through the transmission assembly 7.

[0028] The drive component 62 is located on one side of the device box 613;

[0029] The rotating assembly 63 is located on one side of the concave plate 611.

[0030] The inner wall of the equipment box 613 is equipped with symmetrical positioning rods, and the surface of the positioning rods is slidably connected to a sliding plate 614. The positioning rods are used to limit the sliding of the sliding plate 614. The support arm 3 is rotated inside the crane body 1 by a motor.

[0031] In this embodiment, the transmission assembly 7 includes a folded plate 71 that is slidably installed inside the equipment box 613. One end of the folded plate 71 is fixedly connected to the top of the adjusting plate 616, and the other end of the folded plate 71 is fixedly connected to a transmission rod 72. One end of the transmission rod 72 is fixedly connected to a transmission block 73, and the surface of the transmission block 73 is slidably connected to the inner surface of the inclined slide groove 615.

[0032] In this embodiment, the drive assembly 62 includes a drive motor 621 installed on one side of the device box 613. One end of the output shaft of the drive motor 621 is fixedly connected to a drive screw 622 via a coupling. One end of the drive screw 622 is rotatably connected to the inner wall of the device box 613. The surface of the drive screw 622 is threadedly connected to the inside of the sliding plate 614.

[0033] The drive motor 621 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0034] By starting the drive motor 621, the drive screw 622 is driven to rotate. The rotation of the drive screw 622 causes the sliding plate 614 to slide. The sliding of the sliding plate 614 causes the transmission block 73 to slide on the inner surface of the inclined slide groove 615. This causes the transmission blocks 73, transmission rods 72, and folded plates 71 on both sides to slide synchronously to the opposite side. The sliding of the folded plates 71 causes the adjusting plates 616 on both sides to move synchronously. The adjusting plates 616 on both sides clamp the two sides of the prefabricated stair body 2. With the adjustment mechanism 6, the distance between the adjusting plates 616 on both sides can be flexibly adjusted by the drive motor 621. Thus, the multiple sets of adjusting plates 616 on both sides can clamp and fix the prefabricated stair body 2 of different sizes, so that the prefabricated stair body 2 remains stable during subsequent installation and movement, thus improving the installation quality of the prefabricated stair body 2.

[0035] In this embodiment, the rotating assembly 63 includes a rotating motor 631 mounted on one side of the concave plate 611 and a rotating bevel gear 632 mounted on the surface of the support shaft 612. One end of the output shaft of the rotating motor 631 is fixedly connected to the rotating bevel gear 633 through a coupling, and the surface of the rotating bevel gear 633 meshes with the surface of the rotating bevel gear 632.

[0036] The rotating motor 631 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0037] In this embodiment, the hoisting mechanism 5 includes a control motor 51 installed at the bottom of the bearing plate 4. One end of the output shaft of the control motor 51 is fixedly connected to a control bevel gear 52 via a coupling. The surface of the control bevel gear 52 moves the hook 54 via a linkage component 53.

[0038] The control motor 51 is a three-phase asynchronous motor and is connected to an external circuit via wires.

[0039] In this embodiment, the linkage assembly 53 includes a linkage rod 531 rotatably mounted on the top of the support plate 4. A linkage bevel gear 532 is fixedly connected to the surface of the linkage rod 531. The surface of the linkage bevel gear 532 meshes with the surface of the control bevel gear 52. A steel cable 533 is sleeved on the surface of the linkage rod 531. One end of the steel cable 533 is fixedly connected to the top of the hook 54.

[0040] Symmetrical limiting rings are installed on both sides of the bearing plate 4. The steel cable 533 passes through the limiting rings and is limited by the limiting rings. Guide wheels are installed on both sides of the top of the bearing plate 4, and the surface of the steel cable 533 is in contact with the surface of the guide wheel.

[0041] With the hoisting mechanism 5 in place, the steel cables 533 and hooks 54 on both sides can be hoisted simultaneously by the two sets of control motors 51. Driven by the control motor 51 on one side, the balance of the prefabricated stair body 2 after hoisting can be better adjusted, reducing the possibility of the prefabricated stair body 2 tipping over. With the rotating component 63 in place, the rotation angle of the prefabricated stair body 2 can be finely adjusted by the rotating motor 631, which facilitates subsequent installation operations.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] During operation, the lifting ring is first pre-embedded in the mounting hole at the top of the precast staircase body 2. Then, the crane body 1 is started by connecting an external power source, and the support arm 3 and the bearing plate 4 are moved above the precast staircase body 2. After connecting the hook 54 to the lifting ring, the control motor 51 is started to drive the control bevel gear 52 to rotate. The rotation of the control bevel gear 52 drives the linkage bevel gear 532 and the linkage rod 531 to rotate synchronously. The rotation of the linkage rod 531 pulls the steel cable 533 and the hook 54, thereby lifting the precast staircase body 2 through the hook 54. After the precast staircase body 2 is lifted to the inside of the adjusting plate 616, the drive motor 621 is started to drive the drive screw 622 to rotate. The rotation of the drive screw 622 causes the sliding plate 614 to slide. The sliding plate 614 causes the transmission... The moving block 73 slides on the inner surface of the inclined slide groove 615, thereby causing the transmission blocks 73, transmission rods 72 and folded plates 71 on both sides to slide synchronously to the opposite side. The sliding of the folded plates 71 drives the adjusting plates 616 on both sides to move synchronously. The adjusting plates 616 on both sides clamp the two sides of the prefabricated stair body 2, thereby maintaining the stability of the prefabricated stair body 2 during subsequent installation and movement. At the same time, by starting the rotating motor 631, the rotating bevel gear 633 is driven to rotate. The rotation of the rotating bevel gear 633 will drive the rotating bevel gear 632 and the support shaft 612 to rotate synchronously. The rotation of the support shaft 612 will drive the entire equipment box 613 to start rotating. Then, the adjusting plates 616 can realize the small-angle adjustment operation of the prefabricated stair body 2 as a whole, thereby facilitating the subsequent installation operation.
