Overhead support allowing rooting position displacement

Abstract

The overhead support allowing the rooting position to move comprises a rooting structure, a support structure, a concrete foundation and a heating pipeline, the lower portion of the rooting structure is connected with the support structure, the upper portion of the rooting structure is connected with the concrete foundation, and the heating pipeline is arranged in the support structure. The overhead support allowing the rooting position to move has the beneficial effects that the elliptical groove is formed in the bearing part of the rooting structure, so that a steel rod placed in the elliptical groove is allowed to move along the elliptical groove when being pulled; and by arranging the spring, the steel rod can be reset after the pulling force is reduced. The invention solves the problem that the overhead bracket is easy to damage due to overlarge stress at the root of the bracket caused by thermal expansion and cold contraction of a heat supply pipeline, and provides a novel design form of the rooting part of the overhead bracket, so that the stability of the overhead bracket and the pipeline can be ensured; and the impact of thermal expansion and cold contraction of the pipeline on the overhead bracket is reduced by allowing the rooting part of the overhead bracket to axially displace.

Description

Technical Field

[0001] The invention relates to the technical field of engineering construction, and in particular to an overhead support allowing displacement of a rooting position. Background Art

[0002] The rooting part is the structural part that connects the bracket to the surrounding steel structure frame, concrete foundation or equipment. During the use of the overhead bracket, it will be affected by the weight of the bracket, the gravity of the pipeline, and the thrust caused by the thermal expansion and contraction of the pipeline. The above combined forces will be mainly borne by the rooting part, resulting in the maximum stress in the rooting part.

[0003] For example, a Chinese patent discloses an overhead wire suspension bracket for underground tunnels (publication number: CN217841739U), which belongs to the field of mining production equipment. It includes an anchor rod, a fixing frame, an adjustment device, an insulating mechanism and a wire clamp; the upper end of the anchor rod extends into the upper end of the tunnel roof and is fixed, and the lower end is fixedly connected to the fixing frame; the adjustment device is installed on the fixing frame to adjust the position of the insulating mechanism in the height direction; the wire clamp is fixedly installed at the lower end of the insulating mechanism to clamp the overhead wire. The overhead wire is stably installed, easy to repair and maintain, and the overall position adjustment is convenient, which is conducive to the normal operation of mining production.

[0004] At present, the rooting part of the overhead support is not allowed to move. When the rooting part is subjected to excessive force, the expansion bolt will be broken, thereby causing the pipeline to deform or be damaged. In order to avoid the above situation, a new overhead support rooting structure can be provided. This structure allows axial displacement of the rooting part while ensuring the provision of tension, thereby ensuring the safe operation of the overhead support.

[0005] Therefore, it is necessary to propose an overhead support that allows the rooting position to be displaced to solve the above problems. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide an overhead support that allows displacement of the rooting position, so as to solve the above-mentioned problems.
