Telescopic boom of walking hanging scaffold

Abstract

A telescopic boom of a walking hanging scaffold mainly consists of a slide wedge component and a power component providing power for the slide wedge component. The power component comprises a wedge corner connecting seat fixed on a ring beam, the wedge corner connecting seat is provided with a single-lug support, and a hydraulic cylinder is fixed on the single-lug support via a hinge pin; the slide wedge component comprises guide grooves which are symmetrically arranged on two sides of the wedge corner connecting seat, sliding wedge blocks are respectively arranged in the guide grooves, hinge supports are respectively disposed on two opposite surfaces of the two sliding wedge blocks, a double-lug slide sleeve is penetratingly sleeved on a piston rod of the hydraulic cylinder, a double-lug shaft penetrates in a single-lug hole of the piston rod, two single lugs of the double-lug shaft are respectively hinged with the hinge supports welded on the two sliding wedge blocks via hinge pins, an opposite screwing lead screw, a positioning lead screw and the double-lug slide sleeve form an opposite screwing component, the hydraulic cylinder drives the wedge blocks to move on a guide track so as to control a gap between each wedge block and a well wall, deformation of the well wall can be adapted conveniently, walking positioning is omitted, a large quantity of precisely prefabricated beam pits are omitted, complexity of wall building process is reduced, and damage to the integral well wall is avoided.

Description

technical field [0001] The invention relates to a telescopic arm of a stepping suspension plate, in particular to a telescopic arm of a stepping suspension plate which is suitable for excavating an ultra-deep vertical shaft. Background technique [0002] The currently used step suspension plate adopts a beam-inserting structure, that is, the suspension plate is parked on the well wall by inserting the beam into the prefabricated beam nest on the well wall. Since this structure needs to accurately prefabricate a large number of beam sockets on the well wall, this not only increases the construction cost, but also affects the overall strength of the well wall. At the same time, due to the need for precise positioning when inserting the beam into the beam socket, the operation is difficult, time-consuming and labor-intensive. Contents of the invention [0003] Technical problem: The purpose of the present invention is to overcome the deficiencies in the prior art, and provid...
