Abstract

The present invention discloses an iron tower installation device, comprising: a base platform, a main support, a first long screw, a fixed cylinder, a movable cylinder, a tensioning screw, and a steel wire rope. The fixed cylinder is installed by arranging a second long screw structure, and a movable cylinder that can slide up and down by being manipulated by the tensioning screw is arranged above the fixed cylinder. The top outer side of the fixed cylinder is fixedly connected with a first flange part, the top outer side of the movable cylinder is fixedly connected with a second flange part, and a crossbeam frame is fixedly connected between two main supports located on the same side. The top end of the steel wire rope is fixed to the crossbeam frame, and the bottom end of the steel wire rope is fixed to the first flange part after passing through a guide hole on the second flange part. By relying on the stabilizing force applied to the main support toward the center by the steel wire rope, the ability of the power iron tower to resist crosswinds can be improved.

DETAILED DESCRIPTION

[0026] The invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] refer to Figures 1 to 4 A tower installation device includes: a base platform 1, a main bracket 19, a first long screw 5, a fixed cylinder 8, a movable cylinder 12, a tensioning screw 15, and a wire rope 18.

[0028] Among them, the base 1 is formed by pouring steel bars and concrete on the ground as a stable foundation; the main bracket 19 is an angle steel structure, and the bottom end of the main bracket 19 is fixedly connected to the mounting foot 11, and the mounting foot 11 is provided with a circular hole. The main bracket 19 is provided with four groups and distributed in a rectangular shape. The iron tower composed of the four groups of main brackets 19 is a structure that is thick at the bottom and thin at the top. A number of oblique and horizontally pulled angle steel structures are also arranged between the four groups of main brackets 19 as needed, so that the whole has a higher stability (the accompanying drawings only show four groups of main brackets 19, and the oblique and horizontal pulling Angle steel is not drawn); A crossbeam frame 20 is fixedly connected between the two main supports 19 on the same side. The crossbeam frame 20 can increase the stability of the tower structure itself and is also used to be fixedly connected to the wire rope 18. The bottom end of the first long screw 5 is embedded in the interior of the base 1 and is fixedly connected to the steel bar of the base 1. The top of the first long screw 5 passes through the round hole on the mounting foot 11 and is threadedly connected with a clamping nut. The bottom end of each mounting foot 11 corresponds to three groups of first long screws 5, and the three groups of first long screws 5 are distributed at the three vertices of a right triangle; the foundation A notch 3 is provided in the middle of the top of the platform 1, and a second long screw 7 is provided at the inner bottom of the notch 3. The bottom end of the second long screw 7 is embedded in the interior of the base platform 1 and is fixedly connected to the steel bar of the base platform 1. A through hole 6 is provided at the bottom end of the fixed cylinder 8. The top end of the second long screw 7 passes through the through hole 6 and is threadedly connected to a compression nut. The top outer side of the fixed cylinder 8 is fixedly connected to a first flange 9, and the first flange 9 is provided with four annular mounting holes 10; the movable cylinder 12 is located on the inner side of the fixed cylinder 8, and there is a hole 6 between the movable cylinder 12 and the fixed cylinder 8. The movable cylinder 12 is connected by sliding downward, and a second flange portion 13 is fixedly connected to the outer side of the top of the movable cylinder 12. The second flange portion 13 is provided with guide holes 14 corresponding to the position and number of the mounting holes 10; the second flange portion 13 is provided with threaded holes staggered from the guide holes 14, and the tensioning screw 15 is threadedly connected to the threaded hole, and the bottom end is pressed against the top of the first flange portion 9; the top end of the wire rope 18 is fixedly connected to the crossbeam frame 20, and the bottom end of the wire rope 18 passes through the guide hole 14 and the mounting hole 10 in sequence, and the bottom end of the wire rope 18 is fixedly connected to the fixed cylinder 8.

[0029] Among them, the first long screw 5 and the second long screw 7 are welded and fixed to the steel bars when the steel bars are bundled inside the foundation 1. After pouring concrete, the bottom ends of the first long screw 5 and the second long screw 7 are embedded in the concrete, and the top ends are exposed for installing the iron tower.

[0030] A section from the top end of the steel wire rope 13 to the top of the guide hole 14 is in an inclined state, and a section from the bottom end of the steel wire rope 13 to the top of the guide hole 14 is in a vertical state.

[0031] like Figure 1After the installation is completed, the user rotates the tensioning screw 15, which screws it downward and the bottom end presses against the top of the first flange part 9, so that the second flange part 13 and the movable cylinder 12 move upward synchronously. Relying on the guiding effect of the fixed cylinder 8, the stable movement of the second flange part 13 and the movable cylinder 12 can be guaranteed. In the process of the second flange part 13 moving upward, the part of the wire rope 13 in the vertical state increases, and the part in the inclined state is smaller. In this process, the wire rope 13 will be tensioned and adjusted, which is very convenient to use.

[0032] Reference Attachment Figure 3 In one embodiment, a pad 4 is fixedly connected between the three groups of first long screws 5 corresponding to the same mounting foot 11, and the pad 4 is located between the bottom of the mounting foot 11 and the top of the base platform 1.

[0033] The purpose of designing the pad 4 is to separate the bottom of the mounting foot 11 from the top of the base 1. The top of the base 1 is a concrete surface. If there is long-term friction movement (a slight swing will occur during the use of the tower), the concrete surface will be damaged and the ground of the mounting foot 11 will be easily damaged. The provision of the pad 4 can increase the service life of the tower.

[0034] Reference Attachment Figure 2 In one embodiment, a frustum portion 2 is fixedly connected to the bottom of the base platform 1 and directly below the notch portion 3 .

[0035] The truncated cone portion 2 and the base platform 1 are an integrated structure. The truncated cone portion 2 is designed to compensate for the influence of the recessed portion 3 on the base platform 1 so that the base platform 1 has a stable structure. The base platform 1 preferably adopts a quadrangular cone shape with a larger bottom and a larger bottom.

[0036] Reference Attachment Figure 1 In one embodiment, a vertical slot hole 21 is opened on the side of the crossbeam frame 20, and the top end of the wire rope 18 passes through the vertical slot hole 21 and is fixedly connected to the end block.

[0037] Reference Attachment Figure 3-Figure 4 In one embodiment, the bottom end of the tensioning screw 15 is fixedly connected to a presser foot 16, which is a truncated cone with a small upper portion and a large lower portion; the top of the first flange portion 9 is located directly below the presser foot 16 and is fixedly connected to a fan-shaped ring-shaped gasket 17.

[0038] The design of the presser foot 16 is to increase the contact area between the bottom end of the tensioning screw 15 and the first flange portion 9 , and the design of the fan-shaped gasket 17 is to protect the top surface of the first flange portion 9 .

[0039] The length of the guide hole 14 is greater than that of the mounting hole 10. The steel wire rope 18 inside the guide hole 14 has a certain length to ensure that the position of the steel wire rope 18 inside and below the guide hole 14 is in a vertical state.

[0040] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
