Electric hoisting bracket for vertical column type cable in cable tunnel

Abstract

The invention discloses an electric hoisting bracket for a vertical column type cable in a cable tunnel. The electric hoisting bracket comprises a stand column, a motor and a rope, wherein a first fixing waist ring, a bolt hole, a second fixing waist ring, a third fixing waist ring and a fourth fixing waist ring are arranged on the stand column. A fixing bolt is arranged on the second fixing waistring, a lifting rod and a first pulley are arranged on the third fixing waist ring, the lifting rod is provided with an adjusting ring, a second pulley and a first connecting ring, and the first connecting ring is connected with a second connecting ring on the fourth fixing waist ring through an auxiliary rope, the bottom end of the stand column is connected with a base, the motor is connected tothe base, the motor is connected with a rolling shaft, the rope is arranged on the rolling shaft, the rope sequentially penetrates through a rope guiding ring, the first pulley, the adjusting ring and the second pulley and is connected with the lifting ring, and the lifting ring is vertically downward to form a single lifting ring, or the lifting ring is connected with the adjusting ring and a movable pulley is arranged on the rope to form a double-suspension ring. According to the electric hoisting bracket, the labor intensity is reduced, and the construction efficiency is improved.

Description

Technical field: [0001] The invention relates to a lifting bracket, in particular to a column type cable electric lifting bracket in a cable tunnel. Background technique: [0002] In recent years, many high-voltage cable tunnels have been intensively put into operation in my country. Due to the small space in the tunnels, many problems have been encountered during the construction process, especially in the cable racking process. Since the cross-section of 220kV cables is 1250 square millimeters and the weight per meter is 37.61 kilograms, then It takes a lot of manpower to lift it up, and because of the inconsistent behavior of the steps, it is easy to damage the outer insulation layer of the cable. Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a column-type cable electric lifting support in a cable tunnel with strong versatility and high degree of mechanization.
