Embodiment 2

[0029] Embodiment 2, the support base 6 is provided with a position relay group connected to the single-chip controller, the position relay group is also connected with the driver of the telescopic oil cylinder 44, and the position relay group includes a 90-degree dynamic-off type relay and a 0-degree dynamic-off type For the relay, the 90-degree dynamic-off relay is arranged on the left side of the turntable 5, and the 0-degree dynamic-off relay is arranged on the rear side of the turntable 5. The coils of the 0-degree dynamic-off relay and the 90-degree dynamic-off relay are in contact The heads are all facing the support seat. When the support seat 6 does not touch the external contact of the position relay group, the working circuit of the telescopic oil cylinder continues to conduct, and the telescopic oil cylinder continues to move; when the support seat 6 contacts the coil external contact of the position relay group, the telescopic oil cylinder When the working circuit ...

Embodiment 3

[0030] In embodiment 3, the hydraulic cylinder 3 is a jacking cylinder and there are two jacking cylinders. The two jacking cylinders are respectively vertically arranged on both sides of the lifting frame 1. The sliding frame is a rectangular frame, and the rectangular frame includes vertical beams, The crossbeam and the inclined beam connected inside the rectangular frame, the vertical beam is a square steel with a closed upper port, the base of the jacking cylinder is fixedly connected to the bottom of the lifting frame, and the end of the telescopic cylinder of the jacking cylinder passes through the square steel The formed channel is connected to the upper port of the square steel. The hydraulic cylinder is designed as a jacking cylinder connected to the upper end of the sliding frame, even if the segment is lifted by jacking, the hydraulic cylinder with the same pressure can provide greater force than the jacking method, so the jacking method is used The mechanical prope...

Embodiment 4

[0032] In Embodiment 4, a displacement sensor connected to the telescopic oil cylinder is installed instead of the position relay group, and the telescopic movement of the telescopic oil cylinder is controlled by the displacement sensor, thereby controlling the precise rotation of the support seat to a specific position. The movement of the support seat can be controlled more precisely by using the displacement sensor, so that the lifting of the segment by the support seat is more stable and reliable. Other structures of this embodiment are the same as Embodiment 1.

[0033] The working process of a shield machine segment fast unloading device of the present invention is as follows: when the segment transport trolley 11 driven by the muck transport vehicle is about to leave the tunnel 12, the segment transport trolley 11 stays on the shield machine segment of the present invention Between the lifting racks of the quick unloading device, after starting the device, the support s...

Abstract

The invention discloses a shield tunneling machine duct piece quick dismantling device. The shield tunneling machine duct piece quick dismantling device comprises two lifting frames which are transversely symmetric about the axial line of a tunnel, each lifting frame is provided with a lifting mechanism, the lifting mechanisms comprise hydraulic oil cylinders, slide frames, rotary bases and supporting bases, the hydraulic oil cylinders are fixedly connected with the slide frames, two supporting frames and two rotary bases are arranged, the two rotary bases are fixed to the bottoms of the slide frames, the supporting frames are horizontally hinged to the rotary bases, telescopic oil cylinders are arranged at the bottoms of the lifting frames, and the two ends of each telescopic oil cylinder are hinged to the bottoms of the corresponding supporting base and the corresponding lifting frame respectively. The shield tunneling machine duct piece quick dismantling device can lift duct pieces with different ring widths, and the rail size, the muck delivering vehicle size and the duct piece delivering small vehicle size in the tunnel do not need to be changed; the duct pieces on the duct piece delivering small vehicle can be safely and quickly dismantled, and the duct piece delivering small vehicle and the muck vehicle do not need to be manually separated from each other; meanwhile, the duct piece delivering small vehicle can directly follow the muck delivering vehicle to be driven out of the tunnel, the marshaling train circulating frequency is reduced, and the construction efficiency is further improved.

Description

technical field [0001] The invention relates to the field of special mechanical equipment for tunnels, in particular to a fast unloading device for segments of a shield machine. Background technique [0002] At present, domestic urban subway construction is developing rapidly. Shield tunnel construction has become the most urban subway tunnel construction because it can complete tunnel excavation, muck transportation and tunnel support at one time, and has the characteristics of safety, high efficiency, environmental protection and high degree of automation. The preferred method of construction. The material used for tunnel support is prefabricated annular reinforced concrete segments with a certain width and thickness. The size of a single ring segment depends on the design diameter of the tunnel. A single ring segment is composed of multiple segments. The configured segment assembly equipment grabs each segment to an appropriate spatial position through movements, rotatio...
