Shield machine is mainly used in constructing tunnel, along with the variation of the market demand, miniature shield machine (diameter≤3m) has become one of development trend of shield machine industry, particularly be applicable to the circular shield machine of the extra small diameter of the shield face diameter≤1m of the laying of city various shallow-layer pipeline, apply widely at municipal drainage pipeline and cable laying field.
For the ease of to there being the tunnel of bend to construct, shield machine is equipped with articulated system.By the impact of the factors such as geostatic shield, engineering design, section of jurisdiction attitude, grouting pressure, the anglec of rotation in geological conditions, excavation face, deviation is there is between actual driving axis and Theoretical Design axis in shield machine in tunneling process, need the attitude of adjustment shield machine in real time, consistent with assumption diagram to ensure actual driving circuit.
But, the push rod of the oil cylinder of existing propelling and articulated system is all fixed on the anterior shield of shield machine, when shield machine straight ahead, this structure can ensure oil cylinder uniformity, have good stability, but when shield machine needs adjustment attitude to ensure that actual driving circuit is consistent with assumption diagram time, this structure must rely on the common action of multiple oil cylinder could realize the pose adjustment of shield machine, and greatly waste the energy, efficiency is low.
Utility model content
The utility model is intended to provide a kind of shield driving and articulated system, to solve oil cylinder inefficient problem when adjusting attitude of shield machine of propelling and articulated system in prior art.
Shield driving in this programme and articulated system, comprise some double-acting type hydraulic jacks, some single-acting formula hydraulic jacks; Described double-acting type hydraulic jack, single-acting formula hydraulic jack to be distributed in middle shield and to be parallel to each other, wherein double-acting type hydraulic jack, single-acting formula hydraulic jack are all fixed with supporting plate with the push rod head of one end, supporting plate can form a complete working face, the push rod of the double-acting type hydraulic jack other end is then hinged on backing, and the cylinder body of single-acting formula hydraulic jack is fixed on middle shield.
Compared with prior art, the utility model has the advantage of: comprise some double-acting type hydraulic jacks, some single-acting formula hydraulic jacks, the push rod of the double-acting type hydraulic jack other end is then hinged on backing, and the cylinder body of single-acting formula hydraulic jack is fixed on middle shield; Double-acting type hydraulic jack both can play the effect advancing anterior shield, the effect pulling backing can be played again, single-acting formula hydraulic jack then has the effect advancing anterior shield, middle shield has the effect connecting anterior shield and backing, the cylinder body of double-acting type hydraulic jack, single-acting formula hydraulic jack is fixed on middle shield, is conducive to reducing shield machine to the requirement of hydraulic jack impulse stroke; And described double-acting type hydraulic jack, single-acting formula hydraulic jack are distributed in middle shield and be parallel to each other, in the progradation of anterior shield, the same tropism of hydraulic jack can be ensured; Wherein double-acting type hydraulic jack, single-acting formula hydraulic jack are all fixed with supporting plate with the push rod head of one end, supporting plate can form a complete working face, supporting plate can be strengthened in anterior shield progradation, the same tropism of hydraulic jack, uniformity, meanwhile supporting plate is some pieces, in turn ensure that hydraulic jack stroke in the course of the work exports and can independently carry out, the fltting speed of single hydraulic jack changes the attitude that can realize adjusting shield machine, ensure that actual driving circuit is consistent with assumption diagram, substantially increase efficiency, save the energy.
Further, in middle shield, establish fixed head, fixed head is provided with some shoulder holes for fixing double-acting type cylinder body of hydraulic oil cylinder and some blind holes for fixing single-acting formula cylinder body of hydraulic oil cylinder; The push rod of the double-acting type hydraulic jack other end can be connected on backing through shoulder hole, double-acting type cylinder body of hydraulic oil cylinder is then resisted against on shoulder hole and carries out action, the afterbody of single-acting formula cylinder body of hydraulic oil cylinder is then directly resisted against in blind hole, realizes double-acting type hydraulic jack, single-acting formula hydraulic jack with middle shield for bearing platform advances anterior shield.
Further, described working face is circular; Circular working face mates more with the shape of shield machine, and area circular in unit perimeter is maximum, and in like manner, the hydraulic jack minimum number of circular arrangement under identical work area, thin device, reduces costs.
Further, described double-acting type hydraulic jack, single-acting formula hydraulic jack are all built-in with stroke sensor; Stroke sensor is connected with PLC control circuit, can be obtained the travel parameters of each hydraulic jack by stroke sensor, thus judges the driving attitude of shield machine, in real time the state of monitoring shield machine, and controls.
