Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a casing hoisting anti-skid device. Background Art
[0002] During the construction of prestressed concrete pipe piles, hydraulic truck cranes are often used to lift the pipe piles. Before lifting, a standardized binding method is selected to tie the wire rope to the pipe piles.
[0003] At present, the basket-type rope-tying method in the parallel lifting and binding method is adopted for lifting from the transport vehicle to the pile stacking place. The pile adopts two lifting points, which are located at the pile end to keep it stable. The lifting from the stacking place to the piling point adopts the lifting and binding lifting point method of equal-section column. The steel wire rope is first tied to one end of the pile. After the steel wire rope is tied, lifting rings are left on both sides. The two hooks at the lower end of the lifting rope on the crane are respectively hooked with the lifting rings on both sides after the steel wire rope is tied to lift the pile. At this time, the pile is in a vertical state when it is lifted. The tied steel wire rope is easy to slide on the surface of the pile and detach from the pile, which is very dangerous. Therefore, it is necessary to provide a casing lifting anti-skid device to solve the above problem. Utility Model Content

[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. The casing hoisting anti-skid device can effectively limit the tied steel wire rope by providing a casing main body to prevent the tied steel wire rope from sliding and falling off. When the No. 1 arc-shaped guard frame and the No. 2 arc-shaped guard frame are aligned and stuck on the outer surface of the pile, the casing main body is pushed to move along the pile to adjust the position. The reinforcing plate and the arc-shaped connecting strip move synchronously, which can effectively push away the sand, gravel and soil attached to the outer surface of the pile, facilitating the effective fixation of the No. 1 arc-shaped guard frame and the No. 2 arc-shaped guard frame in the next step.

DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-5 A casing hoisting anti-skid device is installed on the outer surface of a pipe pile 9, including a casing body 1, the casing body 1 includes a first arc-shaped protective frame 101 and a second arc-shaped protective frame 102, and a plurality of fixing holes 2 are equidistantly provided on the sides where the first arc-shaped protective frame 101 and the second arc-shaped protective frame 102 contact each other, and fixing bolts 3 are arranged in the fixing holes 2. The first arc-shaped protective frame 101 and the second arc-shaped protective frame 102 are away from each other. The surface of the side is provided with an arc-shaped limiting plate 5, and the guide rollers 6 are rotatably provided on both sides of the arc-shaped limiting plate 5.
[0024] Wherein; both ends of the guide roller 6 are provided with a rotating shaft 601, and the upper and lower walls of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are provided with shaft holes for the rotating shaft 601 to pass through. The rotating shaft 601 passes through the shaft hole at one end away from the guide roller 6 and is provided with a limiting cap 602. During the lifting process, the pipe pile 9 gradually stands up. During this process, the hook contacts the wire rope and squeezes the guide roller 6. As the pipe pile 9 stands upright and under the guidance of the guide roller 6, the hook and the wire rope assembly are in a vertical state and fall into the arc-shaped limiting plate 5, reducing the wear and pressure of the wire rope and the hook on the surface of the pipe pile 9.
[0025] Among them; both ends of the lower end surface of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are provided with reinforcement plates 7, and a tightening knob 701 is provided in the center of the reinforcement plate 7. By providing the reinforcement plate 7 and the tightening knob 701, the tightening knob 701 is rotated to press the pipe pile 9, which can effectively further ensure the overall stability and prevent the tied wire rope from driving the casing body 1 to slide away from the pipe pile 9.
[0026] Among them, an arc-shaped connecting strip 8 is arranged between the two reinforcing plates 7 on the lower end surfaces of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102. When the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are aligned and stuck on the outer surface of the pipe pile 9, the casing body 1 is pushed along the pipe pile 9 to adjust the position. The reinforcing plate 7 and the arc-shaped connecting strip 8 move synchronously, which can effectively push away the sand, gravel and soil attached to the outer surface of the pipe pile 9, facilitating the effective fixation of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 in the next step.
[0027] Among them, the inner walls of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are both provided with anti-slip grooves 4, the fixing bolts 3 pass through the fixing holes 2 and are threadedly connected with fixing nuts 301. When the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are aligned and clamped on the outer surface of the pipe pile 9, by passing the fixing bolts 3 through the fixing holes 2 and tightening the fixing nuts 301, it can be effectively ensured that the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 clamp the pipe pile 9.
[0028] Among them, a protective pad 501 is provided on the arc-shaped limiting plate 5. By providing the protective pad 501, the hook and the wire rope can be effectively protected, and the service life of the hook and the wire rope can be extended.
[0029] Working principle: when the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are aligned and clamped on the outer surface of the pipe pile 9, by passing the fixing bolt 3 through the fixing hole 2 and tightening the fixing nut 301, it can be effectively ensured that the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 clamp the pipe pile 9. When the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 are aligned and clamped on the outer surface of the pipe pile 9, in the process of pushing the casing body 1 to move along the pipe pile 9 for position adjustment, the reinforcing plate 7 and the arc-shaped connecting strip 8 move synchronously, which can effectively push away the sand, gravel and soil attached to the outer surface of the pipe pile 9, facilitating the effective fixation of the No. 1 arc-shaped protective frame 101 and the No. 2 arc-shaped protective frame 102 in the next step.
[0030] Furthermore, during the lifting process, the pipe pile 9 gradually stands up. During this process, the hook contacts the wire rope and squeezes the guide roller 6. As the pipe pile 9 stands upright and under the guidance of the guide roller 6, the hook and wire rope assembly is in a vertical state and falls into the arc-shaped limiting plate 5, reducing the wear and pressure of the wire rope and the hook on the surface of the pipe pile 9. The casing body 1 can effectively limit the tied wire rope to prevent the tied wire rope from sliding and falling off.
