AI Technical Summary

Technical Problem

In the prior art, the rubber cover is fixed to the steel strip by rivets, which is easy to come off due to stress, resulting in unstable fixation. After long-term use, the rivet holes become densely packed, affecting the fixing effect, making it difficult to ensure the safe operation of the gantry crane.

Method used

The combination structure of hot-dip galvanized steel plates, nuts, hot-dip galvanized steel bars, threaded holes and bolts is adopted, combined with the design of limit blocks, springs and pull rods to achieve stable installation of the rubber cover. The coordination of limit blocks and mounting bars simplifies the assembly and disassembly process of the cable trough.

Benefits of technology

The stability of the rubber cover and the ease of installation are improved, the operation difficulty and maintenance cost are reduced, the flexibility and maintenance efficiency of the system are enhanced, and the additional costs caused by improper disassembly or excessive time are reduced.

Abstract

The utility model relates to the technical field of processing and application of rubber molds and high polymer materials, and discloses a novel rubber cover plate fixing depression bar which comprises a rubber cover plate, a hot-dip galvanized steel plate is movably installed at the bottom of the rubber cover plate, and a nut is fixedly installed at the bottom of the hot-dip galvanized steel plate. A hot-dip zinc steel bar is fixedly installed in the rubber cover plate, and threaded holes are formed in the nut and the hot-dip zinc steel bar. Compared with a traditional fixing pressing strip, the fixing pressing strip has the advantages that the rubber cover plate can be well fixed conveniently through matching of the rubber cover plate, the hot-dip galvanizing steel strips and the threaded holes, so that the rubber cover plate can be tightly and firmly installed at a designated position, the displacement or falling-off phenomenon is effectively prevented, and the service life of the rubber cover plate is prolonged. Therefore, the stability of the whole structure is obviously enhanced, the installation process of the rubber cover plate becomes simpler, more convenient and faster, and the installation difficulty and the labor-hour cost are greatly reduced.
