Description
Technical Field
The utility model belongs to the technical field of the shield constructs the machine, concretely relates to shield constructs quick-witted section of jurisdiction debugging device.
Background
In recent years, with the rapid development of shield construction technology, the shield construction method gradually becomes a main excavation means due to the characteristics of high efficiency, rapidness, safety and the like. Such mechanized construction equipment is called a full face tunnel boring machine. The method can be divided into circular shields and special shields according to different cross-section structures, the existing circular shields are more, and the excavation diameter is mostly between 2.8 and 16 m. A common precast concrete segment supporting tunnel is constructed by a shield method to improve the supporting quality and safety of the tunnel, a segment erector of a shield machine can grab segments in two modes, namely mechanical grabbing and vacuum grabbing, and generally, the shield machine with the excavation diameter larger than 7m usually adopts a vacuum sucker to grab the segments.
Factory assembly process links need carry out the area load test to the erector to ensure that the erector snatchs the function normal. The erector need frequently place the section of jurisdiction on strutting arrangement in the debugging process, and the section of jurisdiction bottom contacts with strutting arrangement only simultaneously, and when the red blue jar of erector stretches out the stroke the same promptly, snatch the head and just can loosen. Whether strutting arrangement and section of jurisdiction bottom contact simultaneously, direct influence erector debugging efficiency and strutting arrangement's integrity.
Former strutting arrangement comprises 4 shaped steel and 4 package truckles, and the erector is in the debugging in-process, receives the influence of operating personnel debugging skill, and the first strutting arrangement that contacts of section of jurisdiction bottom is general one side earlier, snatchs the head this moment and can't loosen the section of jurisdiction, and operating personnel continues to increase hydro-cylinder extension stroke usually to be section of jurisdiction bottom opposite side contact strutting arrangement to will snatch the head and loosen the section of jurisdiction. In the latter stroke of the oil cylinder, the supporting device can continuously bear a larger downward acting force applied by the oil cylinder on the side where the original duct piece is contacted with the supporting device. At the moment, the acting force is directly transmitted to the wheel, the wheel bearing is easily crushed, the average 2~3 projects need to be replaced by one-time wheels, the cost is high, in addition, the supporting device has no buffer structure, and the section steel is easy to deform due to uneven stress.
