Problems solved by technology

In the current shaft construction process, most of the shaft walls are made while excavating. Among them, the patent application number is "201910924894.6", and the patent name is "A Segment Installation System for Vertical Shaft Construction". Transporting device, the segment lifting device includes a segment crane and a crane track, the crane track includes a horizontal track, a connecting track and a circular track, the horizontal track is fixed on the support frame 1, and the horizontal track passes through the connecting track and the circular track. The track connection, the circular track is fixed on the support frame II, and the circular track is located above the shaft mouth. The method of making the well wall while excavating has a large construction area and low efficiency. It is aimed at the problem of making the well wall while excavating

Embodiment 1

[0030] Embodiment 1: as figure 1 As shown, a segment-assembled derrick includes a frame 17, on which a trolley 10 is slidably arranged, and a cable lowering mechanism is arranged at the end of the frame 17, and the cable lowering mechanism is used for the excavation process of the roadheader. When the middle pipeline is lowered, the trolley 10 is connected with the slag discharge mechanism, and the slag discharge mechanism is driven by the trolley to transfer the slag in the shaft. Cantilever mechanisms 3 are arranged symmetrically on both sides of the frame 17, and the cantilever mechanisms are arranged symmetrically about the center of the shaft. The cantilever mechanism 3 is provided with a crane 4, and several groups of segment lowering devices 5 are arranged symmetrically under the frame 17. The segment lowering device 5 cooperates with the crane 4, and the segment lowering device is used to lift the crane into place and assemble The completed pipe joints are lowered, and...

Embodiment 2

[0038] Embodiment 2: as figure 1 Shown, a kind of working method of segment assembly derrick comprises the following steps:

[0039] S1. Segment installation preparation: first, open the outer shaft wellhead for pretreatment, install the starting pipe joint 1 and the roadheader in the starting shaft in sequence, and then install the segment lowering device 5 and the erection frame 17 symmetrically around the wellhead, and install them on the machine. Cantilever mechanism 3 is installed symmetrically on both sides of frame 17, crane track and crane 4 are set up on the cantilever mechanism 3, walking trolley 10 is erected on frame 17, and the cable lowering mechanism is fixed at the end of frame 17;

[0040] S2. Segment assembly: the segment is lifted by the crane 4 and travels along the specific crane track to a predetermined position for segment assembly. The personnel assemble and connect the segment 2 on the ground, and connect and fix the adjacent segments. After the segme...

Abstract

The invention discloses a segment assembling derrick and a construction method thereof. The segment assembling derrick comprises a frame; a running trolley is arranged on the frame in a sliding manner; a cable lowering mechanism is arranged at the end part of the frame; the running trolley is connected with a slag discharging mechanism; cantilever mechanisms are symmetrically arranged on the two sides of the frame; cranes are arranged on the cantilever mechanisms; a plurality of groups of segment lowering devices are symmetrically arranged under the frame; and the segment lowering devices arematched with the cranes. According to the segment assembling derrick, by erecting the running trolley and the cable lowering mechanism on the frame, the synchronous operation of lowering residue soiland pipelines in a vertical shaft is realized; by using the cantilever mechanisms symmetrically mounted on the two sides of the frame, segments are enabled to be rapidly hoisted conveniently; and meanwhile, under the cooperation of the segment lowering device, the whole ring of segments, which is hoisted in place and assembled, is rapidly lowered to a segment height so as to realize rapid segmentpreparing and assembling; and therefore, the assembling efficiency is high, and the reliability is good.

Description

technical field [0001] The invention relates to the technical field of segment assembly, in particular to a segment assembly derrick and a construction method thereof. Background technique [0002] The segment installation equipment in the construction process of the shaft is a set of special construction machinery equipment for lifting, connecting and fixing and lowering the collecting segments. , mechanics, hydraulics, electricity, control, measurement and other disciplines. [0003] At present, in the construction of underground engineering, such as underground fortifications such as mining shafts, tunnel ventilation shafts, and underground parking lots, shafts are the most convenient passages. In the current shaft construction process, most of the shaft walls are made while excavating. Among them, the patent application number is "201910924894.6", and the patent name is "A Segment Installation System for Vertical Shaft Construction". Transporting device, the segment li...
