Improved bridge maintenance equipment

Abstract

Disclosed is improved bridge maintenance equipment. The improved bridge maintenance equipment includes a frame body and decontamination devices symmetrically mounted on the left and right sides of theframe body. Sliding cavities are formed in the two sides of the frame body symmetrically. Each decontamination device includes a sliding frame mounted in the corresponding sliding cavity in a slidingmode and a rotating frame mounted at the upper end of the sliding frame rotatably. Mounting grooves are further formed in the sliding frames. A first driving machine is fixedly mounted in the side wall of each mounting groove. A force transmitting shaft of each first driving machine is fixedly provided with a tooth wheel. A tooth strip connected with the corresponding tooth wheel in a matched mode is fixedly mounted on the outer circle of the corresponding rotating frame. A sliding groove with an end opening facing a sewage pipe is formed in each rotating frame. An ejector rod extending towards the sewage pipe is mounted in each sliding groove in a sliding mode. A spiral hole with an end opening away from the sewage pipe is formed in each ejector pipe. A first spiral shaft is mounted in each spiral hole in threaded and matched modes. Each first spiral shaft is connected with a second driving machine fixedly mounted in the corresponding rotating frame. Elastic decontamination arms usedfor stretching into the sewage pipe for decontamination are arranged on the end surfaces, facing the sewage pipe, of the rotating frames in a vertical symmetrical mode.

Description

technical field [0001] The invention relates to the technical field of bridge facilities, in particular to an improved bridge maintenance equipment. Background technique [0002] In the infrastructure construction of the bridge, there are many sewage pipes used to discharge sewage, and in the daily maintenance of the bridge, regular cleaning and dredging of the sewage pipes is an important measure to ensure the normal sewage discharge of the bridge. More serious sewage pipes generally adopt the operation steps of dismantling first, dredging and finally cleaning. However, due to the special structure of the sewage pipe, it is difficult to clean the inner wall of the sewage pipe. Many existing mechanical devices are used to clean the inner wall of the sewage pipe. However, these inner wall cleaning devices are complex in structure, and for sewage pipes of different diameters, different cleaning heads often need to be replaced, which is very inconvenient to operate.

[0002] In the infrastructure construction of the bridge, there are many sewage pipes used to discharge sewage, and in the daily maintenance of the bridge, regular cleaning and dredging of the sewage pipes is an important measure to ensure the normal sewage discharge of the bridge. More serious sewage pipes generally adopt the operation steps of dismantling first, dredging and finally cleaning. However, due to the special structure of the sewage pipe, it is difficult to clean the inner wall of the sewage pipe. Many existing mechanical devices are used to clean the inner wall of the sewage pipe. However, these inner wall cleaning devices are complex in structure, and for different diameters of sewage pipes, different cleaning heads often need to be replaced, which is very inconvenient to operate. It is not easy to clean some stubborn stains on the inner wall of sewage pipes, and the cleaning effect is not ideal.
