Description

Technical Field

[0001] This invention relates to the field of prestressed anchor installation technology, and more specifically, to a prestressed anchor installation device and its installation method. Background Technology

[0002] Currently, with the gradual innovation and implementation of new technologies and processes for road and bridge construction, as well as the requirement for aesthetically pleasing road and bridge designs, prestressed concrete is being widely used. Prestressing is generally divided into internal prestressing and external prestressing, and often involves the installation of multiple bundles of steel strands in the same trench. Due to the high strength and long length of the steel strands, the installation of the anchorage system in the prestressed system suffers from low efficiency and high safety risks. Summary of the Invention

[0003] In view of this, the present invention provides a prestressed anchor installation device, comprising: The support includes side frames and crossbeams; there are two side frames arranged opposite each other, and multiple crossbeams arranged in parallel. Each crossbeam is located between two side frames, and each end of the crossbeam is connected to one of the side frames. The height of the side frames is adjustable, and the length of the crossbeams is adjustable. By adjusting the height of the side frames and the length of the crossbeams, the height and width of the support can be adjusted. The lifting track is a sloping arc track, with one end connected to the top of the support and the other end extending downward and outward to a position that is close to the same height as the bottom of the support. A power unit, mounted on the support, is used to pull the anchor to be installed along the lifting track to the top of the support and to the installation position.

[0004] Furthermore, both the side frame and the crossarm are equipped with telescopic devices. The telescopic device extends in the same direction as the height of the side frame, and extends in the same direction as the length adjustment of the crossarm.

[0005] Furthermore, the telescopic device includes two connecting cylinders and a plug rod. The two connecting cylinders are connected to the side frame or the crossbeam respectively. The plug rod and the connecting cylinders are respectively provided with a plurality of first screw holes and a plurality of second screw holes. The plug rod can be inserted into the two connecting cylinders, and the first screw holes and the second screw holes are connected by a first bolt, thereby connecting the two connecting cylinders together through the plug rod. By adjusting the first bolt to connect the first screw holes and the second screw holes at different positions, the length of the telescopic device can be adjusted.

[0006] Furthermore, the side frame includes adjustable legs and connecting rods; the adjustable legs include two legs arranged opposite to each other, and each end of the connecting rod is connected to one of the adjustable legs.

The height of the adjustable legs can be adjusted by connecting the second bolts to the first connecting holes and the second connecting holes.

[0007] Furthermore, the crossarm includes a third sleeve and a fourth sleeve, and the third sleeve can be fitted inside the fourth sleeve. The two sleeves are respectively provided with a plurality of third connecting holes and a fourth connecting hole. By connecting the third bolt to the third connecting hole and the fourth connecting hole, the length of the crossarm can be adjusted, thereby realizing the adjustment of the width of the adjusting bracket.

[0008] Furthermore, the lifting track includes two opposing arc-shaped cantilever rods, which are sloping arc-shaped cantilever rods. One end of each cantilever rod is connected to the top of the corresponding side frame, and the other end extends downward and outward to a position that is close to the same height as the bottom of the support. The relative distance between the two arc-shaped cantilever rods remains constant along their extension trend.

[0009] Furthermore, the power unit is a manual winch, which is mounted on the side frame.

[0010] Furthermore, the lifting cable of the winch passes through the crossarm and connects to the anchor and the winch. A ring is fitted on the crossarm corresponding to the lifting cable. The ring can rotate relative to the crossarm. When the lifting cable passes through the ring, its friction is relatively buffered.

[0011] Furthermore, the first sleeve, the second sleeve, the third sleeve, and the fourth sleeve are all steel pipes.

[0012] Compared with traditional technologies, the prestressed anchor installation device provided by this invention greatly improves construction efficiency and reduces safety hazards caused by installation. Due to the adjustability of the support width and height, the application scenarios of this device are greatly expanded, and it is convenient and quick to assemble and disassemble, thus reducing costs.
