The utility model relates to the construction equipment of tunnel excavation, supporting, specifically is a kind of ascending/decending tunnel excavation supporting operation stand.
Background technology
The development of present national high-speed railway, highway, the tunnel is more and more, and scale is increasing, and the development of other underground construction, and tunnel and underground construction safety, quality are proposed requirements at the higher level.In former tunnel and the underground engineering construction, when adopting artificial hand-held air leg air drill to excavate to lay with anchor pole, owing to excavated the middle restriction of reserving the driving passage than large space of stand, the explosion eye at focal point of working position is difficult to arrange, it is poor to cause excavating moulding, the country rock periphery produces stress and concentrates, and has a strong impact on safety; The conclusive borehole of tunnel excavation drilling depth is a snubber, because the centre position of tradition excavation stand does not have the setting operation platform, cause the position and the angle of snubber can't be arranged in rational position, have a strong impact on the excavation drilling depth, wasted resources such as priming system, wind, water, electricity.When tunnel support is constructed, the anchor bolt construction quality also is to guarantee the most important condition of constructing tunnel process safety, anchor bolt construction was exactly manually to stand on the top of excavation stand in the past, adopt the gas leg type air drill to carry out perforating, install anchor pole, there is following problem in such way: the one,, constructor at excavation stand top is not protected, often because the vibrations of rig cause stone to drop hurts sb.'s feelings; The 2nd, owing to be subjected to the restriction of operating space, the angle of installing anchor pole cannot guarantee, promptly can not be vertical with scar, cannot guarantee the quality of anchor pole.And the existence of the problems referred to above all is because traditional excavation horse structure does not conform to the practice of construction environment, is difficult to guarantee constructor's safety and construction quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of ascending/decending tunnel excavation supporting operation stand, can freely adjust the operating platform of center, tunnel borehole and arch anchor bolt construction, and guarantee constructor's safety and construction quality.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model ascending/decending tunnel excavation supporting operation stand comprises by at least four main vertical beams fixedlys connected the main stand that constitutes with several main beams, the bottom of main stand is equipped with road wheel, on every layer of crossbeam at main stand top the close-network sheet is installed, by fastening devices bottle gouard moved by hands is installed on one deck main beam front and back end at main stand top, the bottom of main stand is provided with the free lifting paralell that is fixedly connected to form by horizontal and vertical hoisting cross beam of arranging, and the free lifting paralell is provided with the stay hook that is connected with the loop chain of bottle gouard moved by hands.
Be furnished with the close-network sheet that is fixed on the hoisting cross beam on the described free lifting paralell.
The described bottle gouard moved by hands that is installed on the main beam of main stand top has four, correspondingly on the free lifting paralell is provided with four stay hooks that are connected with the loop chain of bottle gouard moved by hands.
The utility model is simple in structure, be easy to install, use the utility model ascending/decending tunnel excavation supporting operation stand to carry out tunnel excavation, anchor bolt construction, can realize that the hand-held air drill in tunnel accurately arranges, make tunnel excavation smooth blasting forming, improve the tunnel excavation shaping efficiency, accelerating construction progress, personal security and anchor bolt construction quality when guaranteeing anchor bolt construction, and save time, laborsaving, work efficiency is fast.
