However, there are differences in the step heights of precast stairs, and it is difficult to meet the step heights of different heights, resulting in limitations in use. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a sliding lifting tool suitable for hoisting prefabricated building components.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

A first clamp is arranged at the movable ends of the two simple cranes. Two parallel second sliding rods are rotatably connected to one side of the first clamp through a shaft. The first sliding rods are slidably connected to one side of the two second sliding rods through guide rails. The same second clamp is rotatably connected to one side of the two first sliding rods through a shaft. A limiting component for fixing the first sliding rods is arranged on one side of each of the two second sliding rods. A power component for driving the second clamp to move is arranged on one side of the first clamp.

[0007] As a further scheme of the utility model, the limiting component includes a fixing plate welded to one side of the second sliding rod. A threaded hole penetrating through the fixing plate is opened on one side of the fixing plate, and a threaded rod is threadedly connected in the threaded hole.

[0008] As a further scheme of the utility model, the power component includes a second connecting plate rotatably connected to one side of the first clamp through a shaft. A cylinder is fixed to the bottom of the second connecting plate through bolts. The other end of the cylinder is fixed to a first connecting plate through bolts, and the first connecting plate is rotatably connected to the second clamp.

[0009] As a further solution of the utility model, grooves are formed on one side of each of the two first sliding rods, and friction strips are fixed in the grooves by bolts. One end of each of the two threaded rods is rotatably connected to a friction block through a shaft, and the friction block is in contact with the friction strip.

[0010] As a further solution of the utility model, a plurality of rubber pads are bonded to the opposite surfaces of the first clamping frame and the second clamping frame, and the plurality of rubber pads are evenly distributed.

[0011] As a further solution of the utility model, installation grooves are formed on both sides of the frame body, and auxiliary rollers are rotatably connected between the inner walls on both sides of the installation groove.

[0012] As a further solution of the utility model, two connecting ears are welded to both sides of the frame body, and the two connecting ears are symmetrically distributed.

[0013] As a further solution of the utility model, two support rods are fixed between both sides of the frame body by bolts, and the two support rods are inclined.

[0014] The beneficial effects of the utility model are as follows:

[0015] 1. By providing the first clamping frame and the second clamping frame, the utility model places the staircase between the first clamping frame and the second clamping frame, makes the second clamping frame contact with the smooth surface of the staircase (i.e., the bottom of the staircase), and makes the first clamping frame contact with the steps of the staircase, so that the first clamping frame catches the right angle of the staircase, or the first clamping frame can also contact with one side of the staircase step. The position between the first clamping frame and the second clamping frame is fixed by the limiting component, and the clamping of the staircase is completed, thereby eliminating the influence of the step height on the device and improving the versatility of the device.

[0016] 2. By providing the limiting component, when the threaded rod is rotated to make the friction block out of contact with the friction strip, the fixation between the first sliding rod and the second sliding rod can be released at this time, so that the first sliding rod and the second sliding rod slide relatively. On the contrary, the first sliding rod and the second sliding rod are fixed, and the contact between the friction block and the friction strip can increase the friction force between the threaded rod and the first sliding rod, thereby achieving better fixation of the first sliding rod and the second sliding rod.

[0017] 3. By providing the power component, the air cylinder drives the second clamping frame to move, thereby changing the distance between the second clamping frame and the first clamping frame, and relatively rotating after the first clamping frame and the second clamping frame clamp the staircase to complete the position matching, without jamming, making the device run more conveniently.
