Description
Technical field
The invention belongs to the shield excavation machine technical field, particularly a kind of proving installation that is used for shield cutter master driveability.
Background technology
Shield excavation machine is under the protection of shield shell, carries out subterranean tunnel engineering face excavation and lining cutting and works continuously, and rely on the lifting jack of arranging in the shield shell to push ahead.And the shield tunneling operation is to be undertaken by the cutterhead that face is supported in the main drive system drive that is installed in the anterior shield body.Therefore, cutterhead master drive system is the key core part of shield excavation machine, is that the shield structure is accomplished the main working parts of excavating function.
At present, because the shield cutter diameter is big, weight is big, moment of torsion is big and the variation of driving formation condition, buried depth and parameter, make that shield cutter master driving power fluctuation range is bigger, geological adaptability is stronger.Therefore, for the shield structure that designs behind the given geologic condition, before construction, shield cutter master drive system performance is tested very necessity, it is to guarantee the important measures of driving smoothly of shield structure.
It is existing that test mainly is to carry out through experiment for shield cutter master driveability.Experiment test is owing to need to build the soil box that can experimentize, and the corresponding test soil of configuration and a large amount of sensors, makes the complex structure of a whole set of experimental provision, and the while, cost was also with regard to corresponding increase.
Summary of the invention
The present invention seeks to provides a kind of proving installation that is used for shield cutter master driveability on the basis of not building the experiment soil box, to solve under different working conditions the test of large-scale shield cutter master driveability.
To achieve these goals, the present invention has taked following technical scheme:
The proving installation that is used for shield cutter master driveability; Comprise the loading disc that is connected with shield cutter master drive system, be fixed in the disc brake on the shield body; The card of said loading disc is provided with the dish type cooling tube; The liquid coolant input end of dish type cooling tube and liquid coolant output terminal are located at the both sides of loading disc respectively and are positioned on the axis of loading disc; The liquid coolant input end of dish type cooling tube is connected with coolant pipe through swivel adapter head with the liquid coolant output terminal, and said disc-brake matches with the rim of loading disc.
It is semicircular spiral embedded groove that the preceding card of said loading disc is provided with xsect, and spiral embedded groove internal fixation has spiral dish type cooling tube.
Said disc brake is that the center evenly is fixed on the shield body along circumference for several with the shield body axis.
Said disc-brake is 4-10.
Be connected with fixed head through web joint on the back card of said loading disc, loading disc is connected with said shield cutter master drive system through fixed head.
Compared with prior art, proving installation provided by the present invention has following beneficial effect:
1) the continuous braking through the control disc-brake realizes the test to cutterhead master drive system performance, and it is simple in structure;
2) realize for the performance test of shield structure under different operating modes through the braking moment of control disc-brake loading disc, easy and simple to handle;
3) proving installation need not built the entity soil box, and adopts cooling device to realize the utilization again of energy, has reduced testing cost.
Below in conjunction with embodiment and accompanying drawing technical scheme of the present invention is described further.
