Thrust device of guy rope hanging basket for bridge construction

Abstract

The invention relates to the technical field of bridge construction, in particular to a thrust device of a guy rope hanging basket for bridge construction. The thrust device comprises a bottom die, awalking mechanism, a thrust mechanism and a fixing mechanism, wherein the walking mechanism is arranged at the top of the bottom die and is detachably connected with the bottom die, the thrust mechanism is arranged at one end corresponding to the walking mechanism and is detachably connected with the walking mechanism, the thrust mechanism is detachably connected with the bottom die, the thrust mechanism comprises a fixing seat, a limiting assembly and a clamping assembly, and the fixing mechanism comprises a support, a stretching assembly and an elastic self-locking assembly. According to thethrust device, a walking sliding seat is driven by the hanging basket to walk on a hanging basket sliding rail, the walking sliding seat drives a steel type tenon and a strip-shaped plate to be inserted into a rectangular groove and an embedding groove respectively, and the steel type tenon and a component supporting the steel type tenon are limited and stabilized, so that the effect of thrustingthe guy rope hanging basket is achieved; and the thrust device is convenient to operate, safe and efficient, and the thrusting and stabilizing efficiency of the guy rope hanging basket is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a thrust device for a dragline hanging basket used in bridge construction. Background technique [0002] A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bridge head plate, conical slope protection, bank protection, diversion engineering, etc. Bridges are not only built for the convenience brought by crossing large rivers and lakes, but also in high-speed With today's development, bridges have already become an important part of urban road traffic. [0003] In the construction of bridges, when the dragline hanging bask...

Problems solved by technology

[0006] The structures of the above two inventions have the following disadvantages: in the first invention, after being installed and fixed, the handle on the threaded ejector rod of the longitudinal adjustment displacement device is rotated to adjust the elongation of the threaded ejector rod so that the threaded ejector rod contacts the rubber anti-slip gasket against Hold the force-bearing wedge-shaped member at the end of the hanging basket to prevent the hanging basket from shifting backwards, but this cannot avoid the wear of the adjusting threaded ejector rod, and the setting of the anti-skid gasket cannot reach the force-bearing wedge-shaped member of the column for a long time; the second In the invention, the adjustment and anchoring of the height of the hanging basket must be completed before installation. After the anchor seat is inserted into the anchor nut of the cable, it is plugged with a steel ring, and then the pull rod is installed. The anchor seat is in close contact with the anchor block by adjusting the anchor nut. The operation can decompose the force, but due to the heavy weight of the hanging basket, the steel ring will be severely worn or even collapsed, so it is not particularly suitable
