Embodiment Construction
[0022] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:
[0023] combine figure 1 — figure 2 As shown, a shield in-situ small chamber installation equipment is mainly composed of a beam 1, two traveling mechanisms 2, two hydraulic telescopic outriggers 3, two hinge devices 4, and two slider booms 5.
[0024] A walking mechanism 2, a hydraulic telescopic support leg 3 and a hinged device 4 form a walking lifting assembly. The two walking lifting assemblies are arranged symmetrically on the left and right ends of the crossbeam 1, and the crossbeam 1 and the two walking lifting assemblies form a "door" shaped lifting frame.
[0025] The lower end of the hydraulic telescopic support leg 3 is installed on the running gear 2, the upper end of the hydraulic telescopic supporting leg 3 is hinged with the end of the crossbeam 1 through the hinge device 4, and the running gear 2 is placed on the front and rear extendin...

The invention discloses in-situ small-underground-chamber mounting equipment of a tunnel shield. The equipment comprises a crossbeam, a traveling mechanism, hydraulic telescopic support legs and hingedevices, wherein lower ends of the hydraulic telescopic support legs are mounted on the traveling mechanism, upper ends of the hydraulic telescopic support legs are hinged to ends of the crossbeam through the hinge devices, the traveling mechanism is placed on a track, which is laid on the ground of a small underground chamber and extends back and forth, two slider type crane jibs are mounted onthe crossbeam in a suspended manner and are jointly used for hoisting the tunnel shield, the hydraulic telescopic support legs are equipped with jacking cylinders and hydraulic locks, and the slider type crane jibs are equipped with transverse moving cylinders and hydraulic locks. Simultaneously, the invention further discloses a mounting method for carrying out tunnel shield in-situ small-underground-chamber mounting by using the in-situ small-underground-chamber mounting equipment of the tunnel shield. The equipment has the characteristics that the lifting capacity is large, the outline dimension is small and a working place can be quickly switched, and is very application to TBM (Tunnel Boring Machine) assembling operation in small underground chambers or a variety of originating tunnels, then, the construction period can be shortened, the total cost is reduced; the equipment is safe and reliable, and human resources are saved.
Description
technical field [0001] The invention relates to shield machine in-situ small chamber installation equipment and an installation method, which can realize in-situ hoisting, turning, lateral movement, rotation and other working conditions of a shield machine (TBM) in a small chamber. Background technique [0002] How to improve the progress of tunnel shield installation, ensure the construction safety of construction personnel, and reduce construction costs has always been a difficult problem that needs to be continuously solved in the field of shield tunnel construction. [0003] At present, bridge cranes are considered to be the most ideal equipment for installing shield tunnels in tunnels, but for the installation of shield tunnels in small chambers, bridge cranes have little effect, and the external dimensions of bridge cranes are large, which will cause A large amount of earthwork and support operations seriously affected the construction period. And if there are multipl...
