Embodiment 3

[0033] Embodiment 3, a kind of laying method applicable to the flue plate laying machine of large diameter, the steps are as follows: as Figure 1~2 Shown as: S1: The active trailer 1 is located at the rear of the backstage trailer of the roadheader. During the tunneling process of the roadheader, the active trailer 1 moves in the same direction with the roadheader under the action of the wheel set driving mechanism 3 .

[0034] S2: The rotation angle of the slewing system 4 is at 0°. The electric hoist crane 501 of the hoisting system 5 lifts the flue plate 6 in the axial direction and slowly rises. When hoisting the flue plate 6, it is controlled by the load cell Lift the weight to prevent overloading.

[0035] S3: When the flue plate lifting height is higher than the flue plate support base 11 fixed on the upper part of the segment, the slewing system 4 rotates 90° in the forward direction or 90° in the reverse direction, so that the slewing angle of the slewing system 4 is...

Abstract

The invention discloses a flue plate laying machine applicable to a large-diameter flue plate and a laying method thereof, and solves the problems that in the prior art, operation of a flue plate laying device and tunneling cannot be performed simultaneously and the working efficiency is low. The flue plate laying machine comprises an active trailer, wherein a hoisting frame is arranged on the active trailer, a rotary system is arranged on the hoisting frame, a hoisting system for hoisting the flue plate is arranged on the rotary system, the rotary system can drive the hoisting system to rotate, and the rotary system and the hoisting system are connected with a power-control system on the active trailer. According to the flue plate laying machine applicable to the large-diameter flue plateand the laying method thereof, the flue plate is lifted up through the hoisting system, when the lifting height of the flue plate is higher than that of a flue plate supporting base, the rotary system rotates the flue plate by 90 degrees, the trailer is driven to move back and forth through a wheel pair driving device, the flue plate is placed at a target position, and efficient laying of the flue plate is realized.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a flue plate laying machine suitable for large diameters and a laying method thereof. Background technique [0002] With the development of sponge cities, more and more underground development projects are constructed with large-diameter shield machines. Inverted arches need to be laid at the bottom of large-diameter tunnels, and ventilation channels need to be designed at the top. At this stage, inverted arches have been laid synchronously, but the laying of flue slabs for ventilation channels is mostly carried out after the tunnel construction is completed. The flue plate is located on the upper part of the tunnel section and forms a ventilation channel with the tunnel roof. The construction method is generally to build supports on site, pour flue panels on site, or install prefabricated flue panels with forklifts such as the application number 201810459709.6, the ...
