Hoisting machine with pipe cavity frame arc opening rubber supporting pad closing for pipeline construction

Abstract

The invention discloses a hoisting machine with pipe cavity frame arc opening rubber supporting pad closing for pipeline construction. The hoisting machine structurally comprises a hub vehicle chassis, a cab, a transverse penetrating pipeline, a lifting transverse rod, a lazy arm frame, a slide fastener seat and rubber supporting pad lifting plate frames. The transverse penetrating pipeline and the rubber supporting pad lifting plate frames are matched to form the effect of small clamping claws composed of side rubber coating blocks and rubber supporting pad plates on a pipe cavity frame arc opening rubber supporting pad, wrapping and closing of the edge sides of an upper rubber face and a lower rubber face are convenient, an arc face tight pressing-attaching protection effect is achieved,and interference of transverse shaking force with lifting balance of the transverse penetrating pipeline is avoided; then angle adjusting wheel discs are matched to form the limiting degree of left-right external support of strengthening rib vertical plates, the cross pressure of the strengthening rib vertical plates conveniently conducts included angle adjusting work on the top end of the upperedge of a pipe cavity frame opening, and thus the whole hoisting machine achieves the effect of large action displacement on lifting of a transverse lifting pipe and overturning of a longitudinal lifting pipe during pipeline construction; and pipe opening locking is efficient, the phenomenon of balance degree skewing caused by sliding is avoided, and thus the pipeline construction flexibility is improved.

Description

technical field [0001] The invention relates to a hoisting machine for closing a tube lumen frame and an arc mouth rubber pad for pipeline construction, and belongs to the field of pipeline machinery and equipment. Background technique [0002] Conveyor belts are commonly used in pipeline construction and transported by loading vehicles to the construction site, and then the hoisting machinery is used to form the connection and fixation of the hoisting intubation pipe to ensure that the erection of the building construction corridor pipe body can be continuously supplied to the hoisting pipeline installation through the hoisting machinery, improving construction performance and vertical handling Efficiency, the shortcomings to be optimized in the current technology are: [0003] The hoisting and lifting of large-scale pipelines in pipeline construction is the main hoisting operation for erecting water pipes or air pipes in building corridors. This is a rolling friction fixin...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a hoisting machine with closed cavity frame, arc mouth, rubber pad for pipeline construction, so as to solve the problem of hanging and lifting large pipelines during pipeline construction. The main hoisting operation of the water pipe or air pipe is a rolling friction fixed operation that is easy to slip and fall for the round-edged nozzle and the inner cavity of the pipe. Since the conventional hoisting adopts the single-sided hoisting operation of the steel cable, it still needs to be hoisted to the top of the boom. It is very laborious to move and place manually, and because the composite single-strand steel cable is hoisted with low stability and small safety factor, it is easy to cause construction accidents caused by high-altitude falling objects due to broken steel cables, and the locking of the pipeline's self-weight and curved surface sliding mouth The difference in density causes the slope of the pipeline construction and the deflection of the crane arm to cause deviation displacement, which affects the construction process.
