Wheel-type device for bridge floor press-anchoring of stay cable

Abstract

The invention provides a wheel-type device for bridge floor press-anchoring of a stay cable. The wheel-type device comprises an engine, a counter force wheel, a bearing frame, a hoist, a lifting wheeland a transmission shaft, the engine, the counter force wheel and the lifting wheel are all mounted on the bearing frame, the engine and the lifting wheel are coaxial, the transmission shaft is mounted in the bearing frame, the counter force wheel is mounted at one end of the bearing frame, the engine is mounted at the other end of the bearing frame, the hoist is mounted on the bridge floor on the same horizontal plane with the bearing frame, a steel rope is connected with the hoist through the lifting wheel and the counter force wheel, and the lifting wheel is connected with the transmissionshaft. The wheel-type device is reasonable in design, convenient to use, small in equipment size, less in occupied lane, small in traffic influence and suitable for non-interruption traffic cable replacement engineering. According to the structure, the mechanization degree is high, the demand for manpower is less, standardized construction is convenient, the work efficiency is greatly improved, and reliability is high.

Description

technical field [0001] The invention specifically relates to a wheeled device for pressing anchors on cable-stayed bridge decks. Background technique [0002] Anchor pressing on the bridge deck is an important part of the hanging cables of the cable-stayed girders, and the adjustment work before the cables enter the holes is one of the difficulties. The key to hanging the stay cable is how to lead the anchor heads at both ends of the stay cable out of the anchor plates at the upper and lower ends. During the construction process, due to the heavy self-weight and bending rigidity of the stay cables, it is difficult to operate and control them. Therefore, the preparation work for adjusting the cables before entering the hole is the difficulty in the bridge deck anchoring project. Usually, it is necessary to use large-scale Lifting equipment to solve the difficult problem of cable adjustment preparation before entering the hole. At present, the more common bridge deck anchori...

AI Technical Summary

Problems solved by technology

The truck crane and winch cooperate with the anchor pressing method. Since the truck crane needs to occupy a wide lane during the construction process, the construction is usually carried out under the condition of interrupted traffic; the steel box girder hoisting equipment assists in anchor pressing, and the construction cost is high and the equipment scale is large. , not commonly used; temporary gantry auxiliary pressure anchors have limited control ability on the stay cables, and a large amount of manpower is needed to complete the cable adjustment work, and the effect is too low
