Movable bridge outer side construction punching auxiliary device

Abstract

The invention discloses a movable bridge outer side construction punching auxiliary device. A chassis is included. Pedals are arranged above and around the chassis; hanging frames are arranged on thetwo inner sides of the chassis; stepping rods are arranged in the middle of the hanging frames; a locking device is arranged at the top of each hanging frame; and locking bolts are installed on the upper portions of the locking devices, sliding rods are fixedly arranged on the lower portions of the locking devices, hanging lugs are arranged at the ends of the hanging frames, reinforcing rods are arranged on the hanging lugs, supporting rods are arranged on the two outer sides of the chassis, protection strips are arranged on the supporting rods, and anti-skid rubber pads are arranged on the stepping rods and detachably connected with the stepping rods. Problems that in the prior art, a crane is used for bridge outer side construction, moving is inconvenient, cost is high, and consumed timeis long are solved, the sliding rod, the locking devices and the locking bolts are arranged, the position of the sliding rod can be moved according to a width of the outer side surface of a bridge, moving is convenient, and an application range is wide; and the protection strips and the anti-skid rubber pads are arranged so that a safety coefficient is high.

Description

technical field [0001] The invention belongs to the field of construction engineering on the outside of bridges, and in particular relates to a movable auxiliary device for drilling holes on the outside of bridges. Background technique [0002] A bridge is a large structure used to cross obstacles and has an ancient history in China. Bridges were originally structures used to cross traffic routes across natural obstacles (such as rivers, straits, canyons, etc.). Later, with the development of science and technology, the construction of highways, railway lines, and viaducts, bridges have become more and more widely used. At present, in the process of bridge construction, two methods of lifter and hanging basket are usually used for the construction of the outside of the bridge. The lifter method is suitable for bridges raised on the ground level (such as overpass bridges), and the hanging basket method is suitable for bridges with high bridge heights and no support underneat...

AI Technical Summary

Problems solved by technology

[0003] At present, the commonly used construction methods on the outside of the bridge are the above two methods, but the outside of the bridge needs frequent inspection and maintenance, drilling and decoration, etc., no matter whether the lifter or the hanging basket is used, it will block the traffic; and the hanging basket needs to use a crane, which is inconvenient to move and expensive. High and time-consuming; if only short-term operations are carried out on the outside of the bridge, the operator usually only uses simple safety helmets and safety ropes to protect the efficiency, and then works on the outside of the bridge, which has a high risk factor and great potential safety hazards. Factors such as wind force on the outside of the bridge will increase the degree of body shaking and increase the work intensity; therefore, it is necessary to design an auxiliary construction device on the outside of the bridge that is easy to move, has a high safety factor, and has a wide range of applications.
