Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1, a kind of equipment bridge being adapted to two spiral shell machine shield structure, comprises and forms trussed construction by equipment bridge stand beam 1; The front portion of described trussed construction rides on duct piece assembling machine longeron 2; The connection of equipment bridge and duct piece assembling machine longeron 2 is realized by rear matching tractor structure 3; Described equipment bridge stand beam 1 front top is provided with the hanger 4 of deuterostrophies machine 5; Realize deuterostrophies 5(5) lifting at rear portion, equipment bridge stand beam 1 rear portion rides over trailer 6 front top by middle part linkwork 7; Equipment bridge stand beam 1 connects duct piece assembling machine longeron 2 and a trailer 6, function supporting after realizing traction.As shown in Figure 1 and Figure 2, described equipment bridge stand beam 1 is connected with medial support beam 8 by bolt; For fluid, hydraulic pressure, electrically upper pipeline, configuration, fixedly provide enough arrangement space.Equipment bridge front support platform 9 is connected with bottom described medial support beam 8,
Bottom support mechanism is provided with bottom described equipment bridge front support platform 9;
As shown in Figure 4, described deuterostrophies machine 5 is connected by screw rod with between hanger 4;
Described bottom support mechanism comprises and the support slip case 10 be fixedly connected with bottom equipment bridge front support platform 9, and slip case 10 is linked together by buffer spring 11 and bottom spring supporting 12; Described bottom spring supporting 12 is linked together by bolt and bottom support roller box 13; The equipment bridge front support platform 9 on left side and right side links together and is supported on section of jurisdiction by described bottom support roller box 13; Thus define and support roller box by equipment pars basilaris pontis and realize providing support power to equipment bridge middle front part, for top layout deuterostrophies conveyer provides structural condition, reduce the load of equipment bridge stand beam 1 pair of shield pipe sheet assembling machine longeron 2.
Described bottom support mechanism is elastic supporting mechanism, and and be dismountable syndeton between equipment bridge front support platform 9;
Fig. 3 is the utility model patent equipment pars basilaris pontis buffer gear form of structure.According to calculating the pulling force M of deuterostrophies load on equipment bridge, by adjustment theoretical compression size, selecting suitable spring, ensureing, in the distortion of spring effective elasticity, to obtain the support force F close with top-loaded.Due to pipe sheet assembling complete after there is faulting of slab ends, also have in tunneling process and there is the situations such as climbing, descending, take bottom spring supporting system, support force can be controlled in one rationally effective scope, avoid the excessive front portion of causing of support force to tilt, or support force is too small ineffective.
Fig. 4 is the position relationship that deuterostrophies and equipment bridge crane fill.
Described bottom support mechanism has and has following feature, bottom support is elastic construction, due to pipe sheet assembling complete after there is faulting of slab ends, also have in tunneling process and there is the situations such as climbing, descending, cause bottom section of jurisdiction and change with the height of equipment bridge front support platform, as adopted frame for movement directly to connect, will cause the anterior jack-up of equipment bridge or supporting mechanism unsettled, the requirement reducing the load of duct piece assembling machine beam can not be met.Take bottom spring supporting system, support force can be controlled in one rationally effective scope, avoid the excessive front portion of causing of support force to tilt, or support force is too small ineffective.Suppose that the pulling force to equipment bridge of the deuterostrophies conveyer be arranged on equipment bridge is M, then after the support force initial compression of design bottom spring supporting system, the theoretical support force provided is F, and support force F should as far as possible close to pulling force M.Design to float within the scope of spring supporting power ± 20mm, ensure that support force fluctuates in the scope of F ± 10%.This double helix equipment bridge meets on the basis of conventional shield structure host design, arranges two-screw conveyer when reducing load on host computers as far as possible.Realize arranging double-helical condition gushing in comparatively serious stratum, in the stratum that can not gush, dismountable bottom support mechanism, uses as conventional equipment bridge.
The utility model structure is simple, easy for operation, on the basis of conventional shield structure host design, supported by bottom resilient, arrange two-screw conveyer when reducing load on host computers, bottom support is removable, after removing bottom support, also can be applicable to conventional subway earth pressure balanced shield, EPBS, have greatly expanded the accommodation of equipment bridge.
Above embodiment is only for illustration of preferred embodiments of the present utility model; but the utility model is not limited to above-mentioned embodiment; in the ken that described exercising ordinary skill possesses; the any amendment done within the spirit and principles in the present invention, equivalent to substitute and improvement etc., it all should be encompassed within the technical scheme scope of request of the present invention protection.
