Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary structures of bridge engineering, in particular to special equipment for mobile drilling of guardrails. Background Art

[0002] In the conventional (hanging basket + manual drilling) construction method, since the pipeline crossing the bridge is generally located on the outside of the central side guardrail of the left and right sides of the route, and there is only a 50cm gap inside the guardrail, a large movable hanging basket cannot be used for construction. In order to meet the working conditions of the workers outside the guardrail, a small hanging basket that has been processed and modified is often used so that the workers can perform drilling operations on it. The existing technology has the following problems:

[0003] Because the existing construction method requires the hanging basket to be miniaturized and easy to move, the materials used for the hanging basket are often not strong. After a period of use, it is easy to cause fatigue damage, which poses a safety hazard. At the same time, in order to meet the safety of manned operations in a small hanging basket, the hanging basket has not been modified to be able to carry people and move on the guardrail. After completing the drilling construction at one place, the operator needs to return to the bridge deck, move the hanging basket to the next drilling location, and then drill again, and this cycle is repeated, resulting in low construction efficiency.
