Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology for pile foundation construction, and in particular to a suspension hoisting tool for large-diameter pile foundation steel cages. Background Technology

[0002] During pile foundation construction, the reinforcing cage needs to be vertically lifted and installed into the pile hole. The traditional method of lifting the reinforcing cage is to use a crane to lift it using a spreader beam or a circular beam. However, both of these methods have drawbacks. The spreader beam has its lifting holes arranged in a single row on the lower surface of the beam, which is unidirectional and results in weak stability when lifting large-diameter pile foundation reinforcing cages. The circular beam is large and heavy, making it inconvenient to use. Therefore, it is necessary to provide a suspension device for large-diameter pile foundation reinforcing cages that ensures convenient and safe transportation during construction. Utility Model Content

[0005] Furthermore, the virtual central axis formed by connecting the two wing plates along their length direction intersects and coincides perpendicularly with the vertical center line of the first lifting hole on the lifting plate, and the lifting holes on the lifting plate are symmetrically distributed with the intersection and coincidence points.

[0006] Furthermore, the suspended platform is a single-piece structure, and its length is no greater than the length of the suspended beam.

[0007] Furthermore, the lifting plate has symmetrically provided second lifting holes with circular structures at both ends.

[0008] Furthermore, wing plate assemblies are symmetrically welded to both ends of the side portion of the lifting beam with the vertical center line of the first lifting hole as the center. Each wing plate assembly consists of two wing plates, and the two wing plates in each assembly are symmetrically distributed on both sides of the lifting beam with the central axis of the lifting beam along its length as the center line.

[0009] Furthermore, ear plates are welded to both ends of the lifting beam to seal the ends of the lifting beam. An extension section is formed at the lower part of the ear plate, and the height of the extension section is greater than the height of the lifting plate and the width is greater than the width of the lifting beam.

[0010] In the above technical solution, the present invention provides a large-diameter pile foundation steel cage suspension hoist, which, compared with the prior art, has symmetrically welded wing plates on both sides of the middle of the hoisting beam. Both the wing plates and the hoisting plate are provided with hoisting holes.

[0014] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0015] See Figure 1 As shown; A utility model discloses a suspension device for a large-diameter pile foundation steel cage, comprising: a suspension beam 1; The lifting beam 1 is horizontally set. A lifting plate 2 is welded to the upper part of the lifting beam 1 along the length direction. A first lifting hole 6 is opened in the middle of the lifting plate 2. The first lifting hole 6 is located on the vertical axis of the center of the lifting beam 1. A lifting plate 3 is welded to the lower part of the lifting beam 1 along the length direction. Wing plates 4 are symmetrically welded to both sides of the middle part of the lifting beam 1. Lifting holes 8 are opened on both the lifting plate 3 and the lifting plate 3. The wing plates 4 and the lifting plate 3 are arranged in a cross shape. Specifically, the wing plates 4 are arranged perpendicular to the lifting plate 3. In use, the longitudinal and transverse cross shape of the wing plates 4 and the lifting plate 3 is used to lift the steel cage, which improves the lifting stability between the lifting equipment and the steel cage. The virtual central axis formed by the line connecting the two wing plates 4 along their length direction intersects and coincides perpendicularly with the vertical center line of the first lifting hole 21 on the lifting plate 2. The two ends of the lifting beam 1 extend outward symmetrically from the intersection point to ensure that the physical center of gravity of the lifting device can fall on the vertical center line of the first lifting hole 6. The lifting holes 8 on the lifting plate 3 are symmetrically distributed from the intersection point. Preferably, the hanging plate 3 is an integral structure, and its length is no greater than the length of the hanging beam 1. The two ends of the hanging plate 3 extend outward symmetrically at the intersection points. The top of the hanging plate 3 is fixedly connected to the lower surface of the hanging beam 1 by welding. The bottom of the hanging plate 3 has a wavy bottom edge. While ensuring the structural strength of the lifting hole 8, the weight of the hanging plate 3 is reduced as much as possible, which helps to control the overall weight of the lifting device. At the same time, it can ensure that the top edge of the hanging plate 3 has sufficient contact area with the lower surface of the hanging beam 1. Preferably, the lifting plate 2 has symmetrically provided second lifting holes 7 with circular structures at both ends, and a first lifting hole 6 is provided in the middle of the lifting plate 2. The first lifting hole 6 is constructed as an elongated hole, with the diameter of the top circle being larger than the diameter of the bottom circle. The lifting device can be lifted symmetrically through the second lifting hole 7, and can be lifted at a single point through the first lifting hole 6, making it convenient to use. Preferably, the lifting beam 1 has ear plates 5 welded to both ends. The lifting beam 1 can be a profile with a rectangular cross-section, or it can be a rectangular beam formed by four steel plates. The ends of the lifting beam 1 are sealed by the ear plates 5. An extension section is formed at the bottom of the ear plates 5. The height of the extension section is greater than the height of the lifting plate 3 and the width is greater than the width of the lifting beam 1. When the lifting beam 1 lands, the ear plates 5 form support legs, so that the lifting device lands stably on the ground.

[0016] Preferably, wing plate assemblies are symmetrically welded at both ends of the side of the lifting beam 1 with the vertical center line of the first lifting hole 6 as the center. The wing plate assembly consists of two wing plates 4 as a group, and the two wing plates 4 are also symmetrically distributed on both sides of the lifting beam 1 with the central axis of the length direction of the lifting beam 1 as the center line. The wing plate assembly makes it convenient to set longitudinal lifting points at both ends of the lifting beam 1. In the above technical solution, the present invention provides a large-diameter pile foundation reinforcement cage suspension lifting device, the method of use of which is as follows: When in use, the lifting plate 3 is located at any pair of symmetrical lifting holes 8 at both ends of the lifting beam 1 and is connected to the reinforcing cage by steel wire rope. The lifting holes 8 of the wing plates 4 on both sides of the middle part of the lifting beam 1 are connected to the reinforcing cage by steel wire rope. When lifting, the first lifting hole 6 or the two second lifting holes 7 on the lifting plate 2 are connected to the external lifting equipment to complete the lifting operation of the reinforcing cage. The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
