Description

A cable trench opening booster

technical field

The utility model relates to the technical field of cable trench opening, in particular to a cable trench opening booster.

Background technique

The cable trenches in the substation are all made of concrete poured at one time, and the pipes for the primary and secondary cables are not within the design scope. Therefore, no holes for pipe penetrations will be reserved in the initial construction. The cable trench is opened for laying cable conduits. In recent years, due to the increasing number of new substations and reconstruction and expansion work year by year, the work of opening the cable trench wall in the substation has become more and more frequent. The traditional construction method of this work mainly uses impact drills and water drills to directly open holes. However, the quality of the holes made by the impact drills is extremely inconsistent with the provisions of the "Acceptance Specification for Electrical Installation Installation and Construction", so water drills are usually used in the operation. However, in the actual work process, if the rhinestone bit touches hard objects such as steel bars and stones in the concrete structure of the trench wall during the drilling process, a huge torque will be generated instantaneously, which will easily sprain the operator's arm and cause personal injury. Accident, so two people are required to support the rhinestone to work together. In addition, before the opening operation, it is necessary to perform elastic lines and draw lines on the wall of the cable trench to determine the opening position and hole distance. At the same time, due to the limited working space in the cable trench, it is often difficult for the holes to be made to achieve the expected effect and process requirements. In addition, due to the shortcomings of the water drill itself, it cannot be used normally in the opening operation of some specifications of the cable trench in the substation. Therefore, for the construction personnel engaged in the electrical installation of substations, it is urgent to find a safe, convenient and efficient alternative method. At present, there are some assistant tools on the market that are used when the cable trench passes through the pipe hole, such as a "Bracket for the trench wall opening of the cable trench" disclosed in Chinese Patent Document 201320176446.0. The adjustment bolts restrict the position of the drilling holes and the horizontal and vertical directions of the drilling holes respectively, which improves the neatness and uniformity of the drilling holes. The main body of the bracket moves, which is inconvenient to move and increases the labor intensity of the staff.
