AI Technical Summary
When subjected to wind loads, slender towers experience excessive disturbance, affecting the internal components and external flange surfaces of the tower, leading to dimensional deformation and leakage. Existing technology reduces the impact of wind loads by thickening the cylinder wall, but this increases production costs.
A guide bracket is used, including a base plate and a positioning bracket assembly. The positioning and thermal expansion of the tower are achieved through a stop wheel displacement adjustment mechanism and a support member. Multiple sets of positioning bracket assemblies and stop wheel mechanisms are used to protect the tower under wind load and allow the tower to thermally expand under high temperature conditions.
It effectively protects the tower and its internal parts, prevents excessive disturbance, and prolongs its service life. At the same time, it allows thermal expansion of the tower at high temperatures, avoiding the cost increase caused by thickening the cylinder wall.

Abstract
Description
Technical field
[0001] The invention relates to the field of towers, and in particular to a guide bracket for positioning towers. [Background Technology]
[0002] A tower is a vertical device used for mass transfer, heat transfer or chemical reaction. It is widely used in the fields of chemical industry, petroleum, environmental protection, etc. There is a slender tower (that is, a tower with a high height and a small diameter). During our work, we found that this slender tower has excessive disturbance when subjected to wind load. Excessive disturbance will cause the following problems: 1. Affecting the internal parts inside the tower, causing the size of the internal parts to deform, thereby affecting the reaction effect of the medium; 2. Causing deformation of the external flange surface, resulting in leakage. The solution adopted in the existing technology to the above problems is to design the wall thickness of the cylinder to be thicker, so as to reduce the impact of wind load on the equipment. However, the thickening of the cylinder wall thickness will lead to an increase in production costs. Therefore, we are thinking about how to provide a solution to the above problems so that the wall thickness of the cylinder does not need to be increased and the equipment will not be excessively disturbed when subjected to wind load.

[0024] The guide bracket of the present invention is further described in detail below through specific embodiments.
[0025] Ginseng Figures 1 to 8 As shown, a guide bracket includes: a base plate 1 and at least three groups of positioning bracket assemblies 2 arranged above the base plate 1. In this embodiment, the base plate 1 is spliced together by two Haver base plates 10. The base plate 1 is fixed to the ground by a number of ground bolts. A circular receiving groove 11 for receiving the tower 3 is provided in the center of the base plate 1. The number of the positioning bracket assemblies 2 is four, and the four groups of positioning bracket assemblies 2 are evenly arranged along the circumference of the tower 3. Each group of positioning bracket assemblies 2 includes: a wheel stop displacement adjustment mechanism 20, a support member 21, and a wheel stop mechanism 22 arranged above the support member 21. The wheel stop displacement adjustment mechanism 20 includes: a support ear plate 200 welded to the base plate 1, an adjustment bolt 201 inserted into the support ear plate 200, and a nut 202 installed on one side of the support ear plate 200. The support ear plate 200 is arranged perpendicular to the base plate 1.
[0026] The wheel-blocking mechanism 22 includes a connecting base plate 220, a vertical connecting plate 221 welded to the connecting base plate 220, and a first lug plate 222 and a second lug plate 223 welded to the vertical connecting plate 221. The vertical connecting plate 221 is perpendicular to the connecting base plate 220, the first lug plate 222 and the second lug plate 223 are parallel to each other, and both the first lug plate 222 and the second lug plate 223 are perpendicular to the vertical connecting plate 221. A pin 224 passes through the first and second lug plates 222, 223, respectively, so that the wheel-blocking mechanism 225 is mounted on the pin 224 between the first and second lug plates 222, 223. The free end of the pin 224 is fixed to the first lug plate 222 by a clamping plate 226, which is bolted to the first lug plate 222. The free end of the pin 224 is provided with a clamping slot 2240 that cooperates with the clamping plate 226. The connecting base plate 220 is provided with a first elongated hole 2200, and the support member 21 is provided with a second elongated hole 210 corresponding to the first elongated hole 2200. The connecting base plate 220 and the support member 21 are connected by fixing members 4 installed in the first elongated hole 2200 and the second elongated hole 210. In this embodiment, the fixing members 4 are bolts and nuts. There are two first elongated holes 2200 and two second elongated holes 210. The provision of the first elongated holes 2200 and the second elongated holes 210 facilitates radial displacement adjustment of the wheel blocking mechanism 22 in the tower 3.
[0027] The working principle of the guide bracket in the present invention is as follows: first, the pad mechanism 5 is welded to the outer wall of the cylinder of the tower 3 in advance. Because the tower 3 is a pressure vessel and there is pressure in the tower 3, if the blocking wheel 225 directly contacts the outer wall of the tower 3, it will cause damage to the outer wall of the tower 3. Therefore, by welding the pad mechanism 5 to the outer wall of the tower 3, the blocking wheel 225 can be prevented from directly contacting the outer wall of the tower 3. In this embodiment, the pad mechanism 5 includes a pad 50 welded to the outer wall of the tower 3, a connecting pipe 51 welded to the pad 50, and a guide plate 52 welded to the connecting pipe 51. After the pad mechanism 5 is welded to the tower 3, the tower 3 is hoisted into the circular receiving groove 11 of the base plate 1, and then the adjusting bolt 201 on the stop wheel displacement adjustment mechanism 20 is screwed to make the adjusting bolt 201 move toward the tower 3. The adjusting bolt 201 presses against the vertical connecting plate 221 of the stop wheel mechanism 22, thereby pushing the entire stop wheel mechanism 22 toward the tower 3 until the stop wheel 225 of the stop wheel mechanism 22 abuts against the guide plate 52 of the pad mechanism 5. At this time, the position of the stop wheel mechanism 22 is locked by the fixing parts 4 arranged in the first long hole 2200 and the second long hole 210.
[0028] In summary, the guide bracket in the present invention positions the tower by providing multiple groups of positioning bracket assemblies, so that when the tower is subjected to wind load, the disturbance is not too large, thereby protecting the tower and the internal parts therein, and extending the service life of the tower. In addition, the guide bracket in the present invention enables the tower to thermally expand in the up and down directions under high temperature conditions by providing a stop wheel, that is, the guide bracket of the present invention can achieve both positioning the tower in the horizontal direction and causing the tower to produce thermal expansion displacement in the longitudinal direction.
[0029] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some embodiments of its application, and are not intended to limit the present invention. It should be noted that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
