Description

Technical Field

[0001] This utility model relates to the field of iron tower construction technology, specifically to a pole lifting device for iron tower construction. Background Technology

[0002] During the erection of iron towers, the hoisting of tower materials is a core aspect of ensuring project progress and construction safety. The hoisting structure typically employs a gantry crane combined with wire ropes, a steering pulley, and a traction winch. After one stage of hoisting is completed, the gantry crane needs to be raised to proceed to the next stage. Currently, the gantry crane is primarily raised using a traction winch and wire ropes. This involves installing pulleys at the top of the tower splicing section, securing the wire ropes to the bottom of the gantry crane, and then installing multiple waist ropes at the splicing section to limit the gantry crane's swing amplitude. Multiple guy ropes are also needed at the top of the gantry crane to control its lifting direction. The technical problem with this method is that it is cumbersome to operate, requires multiple workers to operate simultaneously, and is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this utility model is to provide a pole lifting device for iron tower construction. This device solves the technical problems of existing technologies, such as cumbersome operation, the need for multiple people to work simultaneously, and the time and labor costs involved.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A gantry lifting device for tower construction includes a mounting bracket, a limiting component, and a guiding component. The mounting bracket is fixedly installed on the tower erection section, and the bottom of the gantry is mounted on the mounting bracket after lifting. The limiting component is detachably mounted on the mounting bracket to limit the swing range of the gantry. The guiding component is located at the top of the tower erection section and includes a top trolley and a limiting ring. The limiting ring is fixedly mounted on the top trolley, and the gantry slides vertically along the limiting ring. One end of a steel wire rope is fixed to the bottom of the gantry, passes through the limiting component and the top trolley in sequence, and is connected to a motorized winch. The motorized winch pulls the gantry upward through the steel wire rope.

[0005] Preferably, the mounting bracket includes a support base and a support arm, the support arm is fixedly mounted on the support base, and a waist-shaped hole with one end open is provided on the support arm.

[0006] Preferably, a connecting shaft is provided at the bottom of the support rod, and the connecting shaft is disposed in the waist-shaped hole.

[0007] Preferably, the limiting component includes a limiting seat, a limiting support shaft, a limiting connecting shaft, and a diagonal brace. The limiting seat is mounted on the mounting bracket, the limiting support shaft is mounted on the limiting seat, the diagonal brace is rotatably mounted on the limiting support shaft, and a plurality of limiting holes are provided on the diagonal brace. The limiting connecting shaft passes through the limiting holes and is connected to the limiting seat.

[0008] Preferably, a limiting part is provided at the front end of the diagonal brace arm, and the retaining rod slides vertically within the limiting part.

[0009] Preferably, a through hole is provided on the diagonal brace arm, through which the wire rope passes.

[0010] Preferably, a connecting hole is provided on the connecting shaft, and the wire rope is connected in the connecting hole.

[0011] In this invention, the mounting bracket is directly fixed to the tower assembly, and the bottom of the pole is connected to the waist-shaped hole of the mounting bracket through a connecting shaft, making installation convenient and eliminating the need for complicated positioning and fixing operations.

[0012] The limiting component is detachably mounted on the mounting bracket. By simply rotating the diagonal brace arm and using the limiting shaft to pass through different limiting holes, its angle can be quickly adjusted to adapt to different installation height requirements. Compared to the complex adjustments of traditional multi-wire ropes, this method is simpler and more direct, reducing the need for manpower. The pole slides vertically within the limiting part. When the pole tends to sway due to external factors such as wind force or uneven tension in the wire rope, the limiting part can promptly prevent large-scale swaying of the pole, limiting it within a safe range.

[0013] The limiting ring in the guide assembly is fixed on the top trolley, and the boom slides vertically along it, which limits the boom's swing amplitude. Unlike the traditional method, there is no need to repeatedly adjust multiple waist ropes to control the boom's swing, which greatly reduces the number of operation steps.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings: like Figures 1 to 4 The illustrated tower construction pole lifting device includes a mounting bracket 1, a limiting component 2, and a guiding component 3. The mounting bracket 1 is fixedly installed on the tower erection section, and the bottom of the pole 4 is installed on the mounting bracket 1 after being lifted. The mounting bracket 1 includes a support base 10 and a support arm 11, the support arm 11 is fixedly installed on the support base 10, and a waist-shaped hole 12 with one end open is provided on the support arm 11.

[0016] A connecting shaft 7 is fixedly installed at the bottom of the mast 4, and the connecting shaft 7 is set inside the oblong hole 12. The connecting shaft 7 is inserted through the opening of the oblong hole 12, making disassembly and assembly simple. A connecting hole is provided on the connecting shaft 7, and the wire rope 5 is connected to the connecting hole when the mast 4 is lifted, making disassembly and assembly convenient.

[0017] The limiting component 2 is detachably mounted on the mounting bracket 1 by fasteners to limit the swing range of the mast 4. The limiting component 2 includes a limiting seat 20, a limiting support shaft 21, a limiting shaft 22, and a diagonal brace 23. The limiting seat 20 is fixedly mounted on the mounting bracket 1 by fasteners. The limiting support shaft 21 is mounted on the limiting seat 20. The diagonal brace 23 is rotatably mounted on the limiting support shaft 21. Multiple limiting holes 24 are provided on the diagonal brace 23. The limiting shaft 22 passes through different limiting holes 24 and is connected to the limiting seat 20, so that the diagonal brace 23 is mounted on the mounting bracket 1 at different angles to adapt to the installation requirements at different height positions of the tower assembly.

[0018] A limiting part 8 is provided at the front end of the diagonal brace 23, and the lifting rod 4 slides vertically within the limiting part 8. In this embodiment, the limiting part 8 is semi-circular in shape. When the lifting rod 4 is adjusted into the limiting part 8, a rope or a semi-circular closed loop is installed at the opening of the limiting part 8 to enclose the lifting rod 4 within the limiting part 8.

[0019] A through hole 9 is provided on the diagonal brace arm 23, through which the wire rope 5 passes. When the wire rope 5 is pulled upward, the bottom of the support pole 4 tends to tilt outward.

[0020] The guide assembly 3 is set on the top of the tower assembly. The guide assembly 3 includes a top trolley 30 and a limiting ring 31. The limiting ring 31 is fixedly set on the top trolley 30. The mast 4 slides vertically along the limiting ring 31. In order to facilitate the assembly and disassembly of the mast 4, the limiting ring 31 is composed of two detachable half rings. When the mast 4 is installed in the two half rings, the two half rings are connected to limit the swing amplitude of the mast 4. After the position of the mast 4 is adjusted, the two half rings can be separated from the mast 4.

[0021] During the lifting operation of the boom 4, one end of the wire rope 5 is fixed to the bottom of the boom 4, and then passes through the limiting component 2 and the top pulley 30 to connect to the motorized winch 6. The operation of the motorized winch 6 is manually controlled, and the boom 4 is lifted by pulling upwards with the wire rope 5. During lifting, a control rope 13 is fixedly installed at the bottom of the boom 4, and the lifting posture of the boom 4 is controlled by manually pulling the control rope 13. After the boom is lifted to the correct position, the tension of the control rope 13 is controlled in conjunction with the pulling of the wire rope 5, so that the connecting shaft 7 is inserted into the waist-shaped hole 12 through the opening of the waist-shaped hole 12, completing the bottom installation of the boom 4 and shortening the subsequent installation time of the boom 4.

[0022] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
