[0020] 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.

[0021] like Figures 1-3 As shown, a prefabricated staircase positioning device includes a support frame 1. Damping grooves 101 are provided on both sides of the support frame 1, and a damping slide 2 is slidably installed on the inner surface of the damping grooves 101. A drive motor 202 is installed on the right side surface of the damping slide 2, and a bidirectional threaded rod 201 is installed at the output end of the drive motor 202. The advantage of this arrangement is that, through the setting of the support frame 1, the damping slide 2 can be supported at the same time, and the damping slide 2 can also be guided as the prefabricated staircase moves downward.

[0022] Furthermore, both ends of the bidirectional threaded rod 201 are spirally fitted with sliding plates 203, and the sliding plates 203 are slidably connected to the front end surface of the damping slide 2. Four buffer components 205 are slidably installed through the surface of the sliding plates 203. The advantage of this setting is that, through the setting of the bidirectional threaded rod 201, the sliding plates 203 on the outer surface can be driven by the drive motor 202 to move the sliding plates 203 on the outer surface inward along the damping slide 2 to position the prefabricated staircase.

[0023] Furthermore, the buffer assembly 205 includes a limiting slide rod 206 disposed on the surface of the sliding plate 203, and a compression spring 207 is disposed on the outer surface of the end of the limiting slide rod 206 away from the sliding plate 203, and a clamping plate 204 is installed on the end of the limiting slide rod 206 close to the sliding plate 203. The advantage of this arrangement is that, by setting the compression spring 207, when using the clamping plate 204 to position and clamp the prefabricated staircase, the speed of the bidirectional threaded rod 201 can be avoided from being too fast, so that the clamping plate 204 exerts excessive pressure on the surface of the prefabricated staircase and causes damage to the surface of the prefabricated staircase. The clamping plate 204 is given a buffer space to protect the prefabricated staircase.

[0024] likeFigure 4 As shown, the outer surface of the sliding plate 203 is provided with a rotating seat 3, and the inner surface of the rotating seat 3 is provided with a rotating rod 301, the outer surface of the rotating rod 301 is provided with a laser positioner 304, and the outer surface of the end of the rotating rod 301 is provided with a threaded groove 302. The advantage of this setting is that through the setting of the rotating laser positioner 304, the position to be installed can be accurately positioned and aligned by laser, making the installation of the prefabricated staircase more accurate.

[0025] Further, the outer surface of the threaded groove 302 is spirally provided with a limiting sleeve 303, and the limiting sleeve 303 and the rotating seat 3 are connected by friction. The advantage of this setting is that through the setting of the limiting sleeve 303, the rotating rod 301 can be fixed by friction to prevent the laser positioner 304 from rotating.

[0026] Further, the lower end surface of the supporting frame 1 is provided with a sliding base 4, and the rear end upper surface of the sliding base 4 is provided with a counterweight 401. The advantage of this setting is that through the setting of the counterweight 401, the stability of the sliding base 4 can be adjusted.

[0027] Working principle: when using the prefabricated staircase positioning device of the assembled structure, first, move the sliding base 4 with the counterweight 401 to the specified position, then move the prefabricated staircase lifted by the crane to the position close to the clamp plate 204, start the driving motor 202 to drive the bidirectional threaded rod 201 to rotate, the outer surface of the sliding plate 203 along the damping slide 2 is inwardly close to the prefabricated staircase to position it, until the inner surface of the clamp plate 204 contacts the outer surface of the prefabricated staircase to complete the fixing, then through the rotating rod 301 drives the laser positioner 304 to determine the position of the prefabricated staircase, then rotate the limiting sleeve 303 into the threaded groove 302 at one end of the rotating rod 301 to make it fit with one side surface of the rotating seat 3 to complete the friction fixing, so that the rotating seat 3 remains firm, finally continue to move the prefabricated staircase downward, while the damping slide 2 will slide downward along the supporting frame 1 and cooperate with the laser positioner 304 to position and install the prefabricated staircase. This is the working principle of the prefabricated staircase positioning device of the assembled structure.
