Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of power transmission pole cap columns, and in particular relates to an assembled anti-torsion chuck connection device of a pre-buried bolt cap column. Background Art
[0002] The cap column is a commonly used component in engineering. It should have good bearing capacity and is an important component connecting the upper structure and the lower foundation. The setting of the cap column can transfer the lateral force and bending moment of the upper steel pipe tower to the cap, and then transfer it to the foundation through the cap, so that the whole structure has stronger anti-overturning performance in the horizontal direction. In engineering construction, due to design errors and engineering quality problems, the foundation of the transmission line tower is deformed and collapsed. In actual working conditions, especially for the embedded bolt cap column, according to the characteristics of the embedded bolts and their longer buried depth in the cap column, the bolts reflect the characteristics of bending components when sheared, and an additional The force makes the bearing column stress complex, which eventually leads to the torsion of the bearing column, and the torque of the embedded bolt bearing column is more than 10 times that of the traditional bearing column. If the torsion cannot be eliminated in time, it will be detrimental to the actual project and will cause certain safety hazards. Therefore, it is necessary to protect the embedded bolt bearing column through an anti-torsion device. At present, in power transmission projects, the existing anti-torsion design generally only resists torsion by thickening the bolts, but with the long-term use of the transmission tower, the bolts will loosen and the loosening amplitude will become larger and larger over time. Therefore, we propose an anti-torsion chuck connection device, which can not only solve the torsion damage of the embedded bolt bearing column, but also solve the problem of bolt loosening.
[0003] Therefore, there is a need for an assembled anti-torsion chuck connection device for a pre-embedded bolt-type cap column to solve the problems in the prior art that the bolts behave like bending members when sheared and the bolts become loose after long-term use. Utility Model Content
[0004] The utility model aims to provide an assembled anti-torsion chuck connection device for a pre-buried bolt-type cap column to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an assembled anti-torsion chuck connection device of a pre-embedded bolt-type pedestal column, comprising an upper chuck, a bolt hole is opened on the surface of the upper chuck, a counterclockwise blade is fixedly connected to the surface of the upper chuck, a clockwise blade is fixedly connected to the surface of the upper chuck, the clockwise blade and the counterclockwise blade constitute an open impeller, and a lower dial is fixedly connected to the bottom surface of the open impeller.
[0006] It should be noted in the plan that the chuck serves as a mechanical device for clamping bolts and precisely positioning bolts, and adopts a rigid connecting rod. The connecting rod and the clockwise blades and counterclockwise blades form an assembled open impeller. The assembled open impeller vertically connects the upper and lower chucks to play the role of connecting the chucks.
[0007] It is further worth explaining that the initial cracks of the torsion specimens generally occur near the midpoint of the long side of the cross-section and are at an angle of about 45° to the axis of the member. After the cracks appear, the concrete is compressed, and the torsional longitudinal reinforcement and stirrups are tensile. The cracking torque of the steel-concrete member section is about 10% to 30% higher than that of the corresponding plain concrete member. The cracks gradually extend to the two edges and many new spiral cracks appear one after another.
[0008] It should be further explained that, according to the development trend of the cracks and the performance after the cracks appear, an anti-torsion device consisting of an open impeller combination is installed between the two chucks to achieve a better anti-torsion effect.
[0009] Compared with the prior art, the utility model provides an assembled anti-torsion chuck connection device for a pre-buried bolt-type cap column, which has at least the following beneficial effects:
[0010] (1) By setting the chuck, on the one hand, the bolts can be clamped to reduce the damage to the pedestal column caused by the loosening of the bolts; on the other hand, the bolts can be accurately positioned and quickly installed. This device can effectively prevent the bolts from loosening due to long-term use, thereby improving the torsion resistance of the pedestal column.
[0011] (2) By setting up an open impeller, the blades of the impeller can resist the torsional damage of the pedestal column, effectively reducing the torsional damage to the pedestal column caused by the bending of the bolts and reducing safety hazards.
[0012] (3) By setting up an open impeller combination, from the structural perspective of the device, the open impeller combination can achieve the stability of the device. From the performance perspective of the device, the open impeller combination consists of clockwise blades and counterclockwise blades, which can fully resist the torsional damage of the base column.
[0013] (4) By setting up an assembled open impeller assembly, the chuck position can be quickly located. The positioning device is easy to assemble and has overall stability, and the entire device can be more conveniently and quickly connected with bolts. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below in conjunction with the embodiments.
[0023] See also Figure 1-7 The utility model provides an assembled anti-torsion chuck connection device of a pre-embedded bolt-type cap column, comprising an upper chuck, a bolt hole 2 is opened on the surface of the upper chuck 1, a counterclockwise blade 3 is fixedly connected to the surface of the upper chuck 1, a clockwise blade 4 is fixedly connected to the surface of the upper chuck 1, and a lower chuck 5 is fixedly connected to the surface of the clockwise blade 4. The upper chuck 1 and the lower chuck 5 are connected by a rigid connecting rod. The number of bolt holes 2 of the upper chuck 1 and the lower chuck 5 is consistent with the number of bolts, the diameter of the bolt hole 2 is the same as the diameter of the bolt, the spacing of the bolt holes 2 is the same as the spacing of the bolts and it is ensured that each bolt can pass through the chuck hole, and the bolt passes through the chuck hole to achieve connection with the assembled anti-torsion device. The counterclockwise blade 3 and the clockwise blade 4 are anti-torsion components, and the anti-torsion component is a semi-open impeller combination. The counterclockwise blade 3 and the clockwise blade 4 are each provided with 6 blades, and a total of 12 blades are provided. The blades are rotated 60° between the blades, and the counterclockwise blade 3 and the clockwise blade 4 are equidistantly distributed, and are distributed in a ring shape with the rigid connecting rod as the center point.
[0024] Further as Figure 1 , Figures 2 to 7 As shown, it is worth explaining in detail that the upper chuck 1 and the lower chuck 5 are connected through an anti-torsion device, and the structures and sizes of the upper chuck 1 and the lower chuck 5 are exactly the same. In order to meet the adaptation of the bolts to the upper chuck 1 and the lower chuck 5, the number of bolt holes 2 of the upper chuck 1 and the lower chuck 5 is consistent with the number of bolts, the diameter of the bolt hole 2 is the same as the diameter of the bolt, the spacing between the bolt holes 2 is the same as the spacing between the bolts and it is ensured that each bolt can pass through the bolt hole 2, and the bolt passes through the bolt hole 2 to achieve connection with the assembled anti-torsion device.
[0025] According to the above working process, it can be known that: by setting the upper chuck 1 and the lower chuck 5, on the one hand, the bolts can be clamped to reduce the damage to the base column caused by the loosening of the bolts, and on the other hand, the bolts can be accurately positioned and the bolts can be quickly installed. The device can effectively avoid the loosening of the bolts caused by long-term use, thereby improving the torsion resistance of the base column. By setting a semi-open impeller, the blades of the impeller can resist the torsional damage of the base column, effectively reducing the torsional damage to the base column caused by the bending of the bolts, and reducing safety hazards. By setting a semi-open impeller combination, from the structural perspective of the device, the semi-open impeller combination can achieve the stability of the device. From the performance perspective of the device, the semi-open impeller combination consists of clockwise blades 4 and counterclockwise blades 3, which fully resist the torsional damage of the base column. By setting an assembled semi-open impeller combination, the upper chuck 1 and the lower chuck 5 can be quickly positioned. The positioning device is easy to assemble and stable as a whole, and can achieve more convenient and rapid connection with bolts for the entire device.
[0026] Further as Figure 1 , Figures 2 to 7 As shown, it is worth explaining in detail that the torsion-resistant component is a semi-open impeller combination, including clockwise blades 4 and counterclockwise blades 5 and a rigid connecting rod. The concrete is torsion-resistant through the blades. There are 6 clockwise blades 4 and 6 counterclockwise blades 3, a total of 12 blades, and the blades are rotated 60° between each other.
[0027] This solution has the following working process: when the user needs to install an anti-torsion device in the pedestal column, first, the prefabricated anti-torsion device needs to be connected to the upper chuck 1 and the lower chuck 5, and then the bolt hole 2 is aligned with the bolt for installation. The upper chuck 1 and the lower chuck 5 play a role in positioning and clamping the bolt to prevent the bolt from loosening and bending after long-term use. The anti-torsion component can not only play a supporting and anti-torsion role in the entire device through blades in different directions, but also connect the upper chuck 1 and the lower chuck 5 to play a role in positioning the upper chuck 1 and the lower chuck 5.
[0028] In summary: by setting the upper chuck 1 and the lower chuck 5, on the one hand, the bolts can be clamped to reduce the damage to the base column caused by the loosening of the bolts. On the other hand, the bolts can be accurately positioned and the bolts can be quickly installed. The device can effectively avoid the loosening of the bolts due to long-term use, thereby improving the torsion resistance of the base column. By setting a semi-open impeller, the blades of the impeller can resist the torsional damage of the base column, effectively reducing the torsional damage to the base column caused by the bending of the bolts, and reducing safety hazards. By setting a semi-open impeller combination, from the structural perspective of the device, the semi-open impeller combination can achieve the stability of the device. From the performance perspective of the device, the semi-open impeller combination consists of clockwise blades 4 and counterclockwise blades 3, which fully resist the torsional damage of the base column. By setting an assembled semi-open impeller combination, the positions of the upper chuck 1 and the lower chuck 5 can be quickly positioned. The positioning device is easy to assemble and stable as a whole, and can achieve more convenient and rapid connection with bolts for the entire device.
