Description

Изобретение относитс к прошлшленности , в частности к бурильным машинам дл проведени проходческих и очистных работ.The invention relates to the past, in particular to drilling machines for carrying out tunneling and cleaning works.

Известна бурильна машина, включающа раму, бурильную головку, буровой инструмент и цепной привод подачи бурильной головки. В устройстве цепной привод подачи имеет цепь, расположенную в осевой плоскости гидроцилиндра подачи, что требует значительных габаритных размеров механизма подачи и бурильной машины .LIT.A known drilling machine includes a frame, a drill head, a drilling tool and a chain drive for feeding the drill head. In the device, the feed chain drive has a chain located in the axial plane of the feed cylinder, which requires significant overall dimensions of the feed mechanism and the boring machine .LIT.

. Недостатками устройства вл ютс большие габариты, а также недостаточнай надежность в работе.. The drawbacks of the device are large dimensions, as well as lack of reliability in operation.

Наиболее близким к предлагаемому :по технической сущности и достигаемому результату вл етс бурильна машина , включающа раму, бурильную головку с салазками, установленными с возможностью перемещени по раме, буровой инструмент и сдвоенный цепной механизм подачи, св занный с гидроприврдом и имеющий уравнитель цепей в виде марнирно установленного коромысла С 2 3.The closest to the proposed one: the technical essence and the achieved result is a boring machine that includes a frame, a drill head with a skid mounted for movement along the frame, a drilling tool and a dual chain feed mechanism associated with a hydraulic actuator and having a chain equalizer in the form of a ground gear. fixed rocker C 2 3.

Недостатком вл етс недостаточна долговечность.The disadvantage is insufficient durability.

Цель изобретени - повышение долговечности бурильной нашины. Дл достижени поставленной цели бурильна с машина, включающа раму; бурильную головку с салазками, установленными с возможностью перемещени по раме, буровой инструмент и сдвоенный цепной механизм подачи, св занный с гидроприводом и имеющий уравнитель цепей в виде шарнирно установленного коромысла, снабжена размещенными в цеп х механизма подачи ползунами, имеющими поперечные пазы, в которых установлены концы коромысла, при этом коромысло закреплено на салазках , которые выполнены с направл ющими пазами дл ползунов.The purpose of the invention is to increase the durability of the boring Nashin. To achieve this goal, the machine is drilling a machine that includes the frame; a drill head with slides mounted for movement along the frame, a drilling tool and a dual chain feed mechanism associated with a hydraulic drive and having an equalizer chains in the form of a pivotally mounted rocker arm, equipped with sliders arranged in chains of the feed mechanism, having transverse grooves in which the ends of the yoke, wherein the yoke is fixed on the slide, which is made with guide slots for the sliders.

На фиг. 1 показана бурильна ма20 шина, вид сбоку; на фиг. 2 - вид А по стрелке на фиг. 1 в положении нат жени рабочих ветвей цепи; на фиг. 3 то же, в положении нат жени холостых ветвей цепи; на Аиг. 4 - вил по стрелке Б на фиг. 2; на фиг, 5 другой вариант исполнени бурильной Г1ашины.FIG. 1 shows a drill bus 20, side view; in fig. 2 is a view A along the arrow in FIG. 1 in the tensioning position of the working branches of the chain; in fig. 3 the same, in the position of tension of the idle branches of the chain; at aig. 4 — fork in arrow B in FIG. 2; Fig. 5 is another embodiment of the drilling pattern.

Claims

Drilling machine contains ragla 1, made with transverse grooves 2, drill head 3 with slide 4, 30 drilling tools 5, dual chain drive mechanism 6 for supplying the drill head / having idle branches 7, working branches 8, hydraulic actuator 9, equalizer chains, made in the form rocker arm 10, sliders 11, made with transverse grooves 12. The device works as follows. When the hydraulic cylinder (Fig. 1 and 5) is moved apart, the chain feed mechanism seizes the sled 4 of the drill head 3, the working branches of 8 chains (Fig. 2) perceive the feeding force, the chains are tensioned and their balance occurs by turning the rocker arm 10 (Fig. 3) relative to the frame of the boring machine. When turning on the reverse stroke of the drill head 3, idling branches 7 (Fig. 2) receive tension and their balancing occurs due to rotation to the opposite side of the faceplate 10 (Fig. 3) relative to the frame 1 of the drill mask. The second variant of the device (Fig. 5 is different in that the sliders are located in the guide grooves of the sled of the drill head 3 and the rocker arm is hinged on the slide of the drill head. - -The proposed boring machine improves the reliability of the chains of the feeder. a frame, a drill head with slides mounted for movement along the frame, a drilling tool and a dual chain feed mechanism associated with a hydraulic drive and having an equalizer circuit in the form of a hinge The raised arm, characterized in that, in order to increase the durability of the drilling machine, it is provided with sliders arranged in the chains of the feed mechanism, having transverse grooves in which the ends of the rocker arms are mounted, while the rocker arm is fixed on the slide, which is made with guide grooves for sliders Sources of information taken into account in the examination 1.
