Self-service lifting device for bridge maintenance

Abstract

A self elevating device for bridge maintenance is provided. The self elevating device for bridge maintenance comprises a lower plate fixedly mounted on the surface of a bridge and an upper plate fixedly mounted on the top of the bridge, two corresponding guide connecting rods on the left and the right and a spiral rod located between the two guide connecting rods are fixedly arranged between the lower plate and the upper plate, an elevating platform is mounted on the spiral rod, guide connecting holes are formed in the left side and the right side of the elevating platform correspondingly, the guide connecting holes and the guide connecting rods are mutually matched, guide connecting sleeves are further mounted on the guide connecting rods in a sliding connection mode, and the upper end surfaces of the guide connecting sleeves are fixedly connected with the lower end surface of the elevating platform; and trilateral plates are fixedly mounted between the front ends of the guide connecting sleeves and the bottom end of the elevating platform, a horizontal groove and a vertical groove communicating with the horizontal groove are formed in each trilateral plate, a sliding connection plate is mounted in a containing cavity of the elevating platform in an up-down sliding connection mode, a sliding rail is arranged in the rear end wall of the containing cavity, and a tool case is mounted on the sliding rail in a left-right sliding connection mode.

Description

technical field [0001] The invention relates to the field of bridge facilities, in particular to a self-service raising device for bridge maintenance. Background technique [0002] With the development of bridge construction technology, the span, load, length and height of bridges have been greatly improved, and the structure of bridges has also developed into girder bridges, arch bridges, suspension bridges, cable-stayed bridges, composite system bridges, etc. Among them, suspension bridges, cable-stayed bridges and composite system bridges have high structures. When it is necessary to maintain the bridges on the top of such bridges, the staff need to use climbing tools and also need to be equipped with safe fall-proof bridges, so that the staff can use It is cumbersome to operate when raising, and it is not easy to carry tools for maintenance. Contents of the invention [0003] The object of the present invention is to provide a self-service elevating device for bridge ...
