Dismantling and hoisting integrated equipment for piers and bearing platforms at lower part of bridge

Abstract

The invention provides dismantling and hoisting integrated equipment for piers and bearing platforms at the lower part of a bridge, relates to the field of bridge construction, and solves the problemsthat organic combination of pier dismantling and hoisting cannot be achieved at the same time, only the hoisting effect can be achieved usually, and explosives need to be thrown into manually drilledholes to burst the piers during dismantling; and after the piers are drilled and exploded into large stones, a grabbing structure of a hoisting device is poor in slip resistance, and the phenomenon that the stones fall off easily in the hoisting process. The dismantling and hoisting integrated equipment for the piers and the bearing platforms at the lower part of the bridge comprises a body seatand a rectangular plate, wherein a clamp plate is welded to the body seat. The head ends of two fixing rods are both of a conical structure, and the tail ends of the two fixing rods are both of a spherical structure; the tail ends of the fixing rods are contact with a cam; when the cam rotates along with a rotating shaft A, the fixing rods are in a reciprocating state, so that the vibration drilling of the fixing rods is achieved, and thus the vertical tension of the rotating shaft A can be reduced through the fixing rods.

Description

technical field [0001] The invention belongs to the technical field of bridge construction, and more specifically relates to an integrated equipment for dismantling, lifting and transporting bridge lower piers and caps. Background technique [0002] With the continuous extension of bridge construction, some bridges that cannot meet the upper load and regional planning will be demolished, and some old and dangerous bridges will also be demolished and replaced for safety reasons. [0003] For example, the application number: CN202010054590.1, the invention discloses a method for dismantling the lower piers and caps of cross-river bridges, including the piers and the caps connected under the piers. The caps within the hole range are designed and removed together with the bridge piers; 2) Determine the horizontal and vertical cutting positions of the bridge piers; 3) Set up the operation platform and cut the bridge piers in blocks; 4) Carry out vertical division of the caps; 5) ...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides an integrated equipment for dismantling and lifting bridge piers and caps at the lower part of the bridge. It can only realize the hoisting function, but it is often necessary to manually drill holes and inject explosives to burst the piers during dismantling, which has low functionality; moreover, after the piers are drilled and exploded into large stones, they often need to be grasped and placed. However, the anti-skid performance of the grasping structure of the hoisting device of the existing device is weak, and it is easy to cause stones to fall during the hoisting process, which is a problem with a high degree of danger
