(54) ИСПОЛНИТЕЛЬНЫЙ ОРГАН ПРОХОДЧЕСКОГО(54) EXECUTIVE BODY

КОМБАЙНАCOMBINE

1one

Изобретение относитс к горной промышленности и может быть применено в стреловидных проходческих комбайнах, разрушающих массив породы режуще-отрывным способом.The invention relates to the mining industry and can be applied in swept tunneling machines, destroying the rock mass in a cutting-tear manner.

Известен исполнительный орган проходческого комбайна, включающий стрелу и режущий диск с гидроотрыБником 1.The executive body of the tunnel miner is known, including an arrow and a cutting disc with a hydraulic bucket 1.

Недостатком такого исполнительного органа вл етс неполный захват надщелевого целика тарелкой отрывника и в результате этого отрыв целика производитс не на полную глубину щели, прорезаемой фрезерным диском.The disadvantage of such an executive body is the incomplete gripping of the slotted rear sight pillar with a tear-off plate and, as a result, the rear-pillar separation is not made to the full depth of the slot cut by the milling disc.

Наиболее близким по технической сущности и достиг.аемому результату к изобрет нию вл етс исполнительный орган проходческого щита, включающий фрезерный диск, установленный на щтоке гидроцилиндра отрыва и выполн ющий функции отрывника 2.The closest in technical essence and achieved result to the invention is the executive body of the tunneling shield, which includes a milling disc mounted on the separation cylinder brush and performing the functions of the detachment 2.

Недостатком этого исполнительного органа вл етс то, что отрыв целика производитс вращающимс фрезерным диском, что снижает его надежность.The disadvantage of this actuator is that the separation of the rear sight is made by a rotating milling disc, which reduces its reliability.

Цель изобретени - повышение надежности работы исполнительного органа.The purpose of the invention is to increase the reliability of the executive body.

Поставленна цель достигаетс тем, что в исполнительном органе проходческого комбайна , включающем гидроцилиндр с отверсти ми в щтоковой и порщневой полост х дл подвода рабочей жидкости, вал сThe goal is achieved by the fact that in the executive body of a tunneling machine, including a hydraulic cylinder with openings in a pinch and piston cavity for supplying the working fluid, the shaft with

На фиг. 1 изображен исполнительный орган в процессе резани ; на фиг. 2 - то же, в процессе отрыва.FIG. 1 shows the executive body in the cutting process; in fig. 2 - the same in the process of separation.

Исполнительный орган работает следующим образом.The executive body works as follows.

Claims

Through the supply 10 into the cavity B of the hydraulic cylinder 8, the working fluid is supplied under pressure, which moves the piston 6 together with the disk 4 along the shaft 1 up to the stop in the second 2. The rod case A is connected to the drain. In this case, the milling disc engages with the shaft by means of splines. The wedge shape of the splines allows engagement almost independently of the mutual position of the latter. The rotating milling disc cuts a slit in the massif with the formation of a slotted rear sight 11. When the maximum sizes are reached, a second destruction cycle begins - separation. Through manual control or automatically, inlet 9 is connected to the head, and inlet 10 is connected to the drain. Inlet 9 is divided into parallel taps, which are movable to the openings of a small and large section. Thus, in this cycle, the rotating g Zhpechepny disk slowly (small cross-section of the supply pressure head) moves the shaft of the shaft in the direction of the gaiter rear sight, in the last channel 12 (Fig. 2). When the disc plane stops in the subglacial pillar, the spline of the disc disengages from the movement of the rod to the disk increases sharply — the subbarking pillar is detached. To return the disk to the cutting position, the inlet 10 is connected to the fc apor, and the inlet 9 is connected to the drain, the milling disc with the rod moves along the ael up to the stop in the fifth, the engagement with the rotating shaft. The use of this technical solution allows to increase the reliability and productivity of the executive body. Clearing to full depth allows excavations with an equal surface along the perimeter. Claims I. An executive body of a sinking combine, including a hydraulic cylinder with holes in a bristle and piston cavity for supplying a working fluid, a shaft with a fifth and hydraulic disk with cutters mounted on a hydraulic cylinder bore, characterized in that, in order to increase by. -, ---. - „„. “Reliability of the work of the executive body. The brush on the shaft is mounted with the ability to move in the sowing direction and interact with the shaft by means of wedge slits.
