Description

Technical Field

[0001] The utility model relates to the technical field of power transmission equipment construction, in particular to an iron tower holding pole supporting structure. Background Art

[0002] When assembling a tower through a suspended pole, in order to keep the pole in a neutral position during lifting, pole waist rings are often set around the pole to keep the pole lifting smoothly. The upper and lower sets of pole waist rings are relatively independent of each other, and a certain offset angle will still appear during the lifting of the pole. In addition, the contact surface between the roller on the pole waist ring and the pole is small, while the size of the outer wall of the pole is large. When the two are in contact, it is easy to cause the rolling contact of the roller on the pole waist ring to be unstable and fluctuate greatly. Therefore, it is necessary to optimize the pole waist ring in the current tower pole support structure. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an iron tower pole support structure which has better stability in pole lifting and is not prone to horizontal deviation during movement.

[0004] The technical problem to be solved by the utility model is achieved through the following technical solution: an iron tower pole support structure, the support structure comprising a pole waist ring frame of a square structure;

[0005] Hanging ears are fixedly provided on the four corners of the pole waist ring frame;

[0006] A pair of short rollers whose outer circumferences can roll in contact with the outer wall of the pole are sleeved on one pair of parallel sides of the pole waist ring frame, and a pair of long rollers whose outer circumferences can roll in contact with the outer wall of the pole are sleeved on the other pair of parallel sides;

[0007] A traction plate is fixedly provided on a pair of side edges of a pole waist ring frame sleeved with a short roller, and a traction hole is opened on the traction plate;

[0008] The upper and lower groups of pole waist ring frames are limited in the vertical direction by ropes penetrating through the traction holes of a plurality of groups of pole waist ring frames arranged on the outer wall of the pole.

[0009] Preferably, each of the traction plates is composed of a pair of traction ear plates, and the pair of traction ear plates are symmetrically fixed on the side outer peripheral surface of the pole waist ring frame.

[0010] Preferably, each of the pair of traction ear plates has a traction hole, and the axes of the traction holes on the upper and lower traction ear plates are collinear.

[0011] Preferably, each pair of the short rollers is symmetrically arranged on the side of the pole waist ring frame;

[0012] Each of the traction plates is located on the pole waist ring frame between a pair of short rollers.

[0013] Preferably, the distance between the two flat end surfaces of the long roller is equal to the distance between the flat end surfaces of a pair of short rollers away from the traction plate.

[0014] Compared with the prior art, the beneficial technical effects of the utility model are:

[0015] (1) As the rollers of traditional pole waist rings are all short rollers with a small contact area, the use of long rollers can increase the contact area with the outer wall of the pole, thereby improving the movement stability of the pole waist ring and avoiding horizontal vibration of the pole waist ring to a certain extent;

[0016] (2) A traction plate is added to one of the pair of side walls of the pole holding waist ring frame, and a traction hole for the rope to pass through is opened on the traction plate. In actual operation, because the pole holding waist ring is not used alone but multiple pole holding waist rings are provided, the ropes passing through the traction holes of multiple pole holding waist ring frames can limit the multiple pole holding waist rings in the vertical direction, further increasing the stability of the pole holding waist ring.

[0020] The specific technical solutions of the present invention are further described below with reference to the accompanying drawings, so as to facilitate further understanding of the present invention by those skilled in the art, and do not constitute any limitation to the rights thereof.

[0021] Example 1, reference Figure 1-2 A tower pole support structure includes a pole waist ring frame 1 of a square structure, and hanging ears 2 are fixedly provided at the four corners of the pole waist ring frame 1. The hanging ears 2 are used to pass through the waist ring steel rope (not shown in the figure), which is a conventional structure of the pole waist ring;

[0022] A pair of short rollers 4 whose outer circumferences can roll in contact with the outer wall of the pole 3 are sleeved on one pair of parallel sides of the pole waist ring frame 1. In order to increase the contact between the pole waist ring frame 1 and the outer wall of the pole 3 and make it more stable, a pair of long rollers 5 whose outer circumferences can roll in contact with the outer wall of the pole 3 are sleeved on the other pair of parallel sides of the pole waist ring frame 1. Since the axial dimension of the long rollers 5 is large, the contact area between the long rollers 5 and the outer wall of the pole 3 can be increased, so that the pole 3 can be better guided and limited when moving up and down, and the stability is better.

[0023] During the actual construction of the suspended pole assembly tower, more than one group of pole waist rings are often arranged on the outer wall of the pole 3 to limit the different height positions of the pole 3 in the horizontal direction. However, there is no auxiliary connection structure between the upper and lower adjacent pole waist rings. Therefore, in order to increase the structural stability between the multiple groups of pole waist rings in the vertical direction, we fix a traction plate 6 on a pair of side edges of the pole waist ring frame 1 on which a short roller 4 is sleeved, and a traction hole 7 is opened on the traction plate 6. The rope 8 passing through the traction hole 7 of several groups of pole waist ring frames 1 arranged on the outer wall of the pole 3 forms a vertical limit for the upper and lower groups of pole waist ring frames 1.

[0024] In addition, in order to improve the use stability of the traction plate 6, each traction plate 6 is designed to be composed of a pair of traction ear plates with the same structure, and the pair of traction ear plates are symmetrically fixed on the side outer peripheral surface of the pole waist ring frame 1. Even if one of the traction ear plates is broken or damaged, the other traction ear plate can still be put into use. The shape of the traction ear plate can be designed to be an arc-shaped sheet structure, and the traction hole 7 thereon can be a round hole;

[0025] It should be noted that each of the pair of traction lugs has a traction hole 7, and the axes of the traction holes 7 on the upper and lower traction lugs are collinear, which ensures that the two traction lugs can be used by the other traction lug if one of the traction lugs is damaged.

[0026] In order to maintain the stability of the short rollers 4, each pair of the short rollers 4 is symmetrically mounted on the side of the pole waist ring frame 1, and each traction plate 6 is mounted on the pole waist ring frame 1 between a pair of short rollers 4;

[0027] In addition, the distance between the two flat end surfaces of the long roller 5 is equal to the distance between the flat end surfaces of a pair of short rollers 4 away from the traction plate 6 .

[0028] When the iron tower pole supporting structure is in use, the pole waist ring is tightened or loosened by the waist ring steel rope to coordinate the vertical movement of the pole 3. In addition, a rope 8 is passed through the traction hole 7 of the traction plate 6. One end of the rope 8 is fixed to the middle part of the iron tower beam, and the other end passes through the traction hole 7 of the pole waist ring from top to bottom, and is wound in a rope winch on the ground. When the pole waist ring needs to be removed, it is only necessary to recycle the rope 8 through the rope winch to carry out the removal operation of the pole waist ring.
