Abstract

The invention discloses a concrete seal cover. The concrete seal cover structurally comprises a fixed base, wherein an annular circular truncated cone is arranged on the fixed base, the circular truncated cone is provided with a threaded hole array consisting of threaded holes, two sides of the bottom of the circular truncated cone are separately provided with a fixed shaft barrel, a hollow coupling shaft is respectively arranged in each fixed shaft barrel, a washer is arranged between head parts of the coupling shafts, two ends of the washer are respectively provided with a washer circular hole, and screws are respectively connected with the washer circular hole and the coupling shaft. Since the circular truncated cone is vertically arranged on the base and the threaded holes are formed in the circular truncated cone, the machining surface is reduced, the working hours are saved, the assembling is facilitated, and the connection tightness and the working reliability are guaranteed by virtue of the threaded holes. Since the screw is connected with the washer, the tightness of the device is guaranteed, the friction surface area is increased, the friction resistance force is increased, and the sliding problem of the device after being stressed is solved.

Description

technical field [0001] The invention relates to a sealing cover, more precisely, a concrete pump sealing cover. Background technique [0002] In the modern construction industry, housing construction and various high-rise buildings are inseparable from construction machinery, especially concrete pumps. The concrete pump sealing cover is an important part of the concrete pump. The height that the concrete pump can punch depends on the sealing degree of the sealing cover. Usually, the seal cover consists of connecting bolts, a seal plate and a support frame. [0003] When in use, the connecting bolts are embedded in the sealing disc to fix the support frame and the sealing disc. However, under normal circumstances, the sealing disc is easily damaged and leaks concrete when subjected to a relatively large pressure. Contents of the invention [0004] The invention mainly solves the technical problems existing in the prior art, thereby providing a concrete pump sealing cover...
