Description

Изобретение относитс к горной промышленности, в частности к устройствам дл центрировани и зажима штанг при бурении шпуров и скважин.The invention relates to the mining industry, in particular, to devices for centering and clamping rods when drilling holes and boreholes.

Известен буродержатель дл направлени штанги при забуривании, состо щий из корпуса с центрирующим отверстием , имеющим косой паз с направл ющими скосами дл установки штанг. Центрирующее отверстие позвол ет выдерживать направление при забуривании 11 .A drill holder for guiding the rod when drilling is known, consisting of a housing with a centering hole having an oblique groove with guide rails for mounting the rods. The centering hole allows you to withstand the direction when drilling 11.

Однако дл штанг, имеющих муфты, . данный буродержатель не пригоден по причине того, что диаметр муфты больше диаметра штанг и муфта не проходит в центрируквдее отверстие. Кроме того, установка штанг производитс под углом к податчику, что не дает возможности установить штангу при расположении податчика у борта выработки .However, for rods with couplings,. This drill holder is not suitable due to the fact that the diameter of the coupling is larger than the diameter of the rods and the coupling does not pass through the hole in the center hole. In addition, the installation of the rods is made at an angle to the feeder, which makes it impossible to install the rod at the location of the feeder at the working side.

Наиболее близким к изобретению решением по технической сущности и достигаемому результату вл етс уст .ройство дл зажИма и направлени штанг, включающее цилиндр, поршень со штоком, зажимные кулачки с рычагами и фиксатор 2.The closest solution to the invention to the technical essence and the achieved result is a device for clamping and guiding the rods, including a cylinder, a piston with a rod, clamping jaws with levers and a latch 2.

су , но в проекции не образует цент5 рирующего отверсти , поэтому не центрирует штангу, что приводит к смещению точки забуривани , к искривлению скважины и, в целом, к нарушению паспорта буровзрывных работ. Наличие , 10 двух цилиндров усложн ет и удорожает устройство, а .их расположение перпендикул рно оси штанг увеличивает габариты , что затрудн ет маневрирование в выработке и затрудн ет бурение параллельных скважин в непосредст15 венной близости от бортов выработки. Это также ведет к нарушению паспорта буровзрывных работ.Su, but in the projection does not form a centering hole, therefore does not center the rod, which leads to a shift of the point of drilling, to the curvature of the well and, in general, to a violation of the passport of drilling and blasting operations. The presence of 10 two cylinders complicates and increases the cost of the device, and their location perpendicular to the axis of the rods increases the size, which makes maneuvering in the development difficult and difficult to drill parallel wells in the immediate vicinity of the production side. It also leads to a violation of the passport blasting.

Claims

25 rods of a boring machine including a cylinder, a piston with a rod, clamping cams with levers and a clamp cars. FIG. 1 shows a device, a general view of FIG. 2 - section A-A in FIG. one; in fig. 3 - device, front view (stop conventionally not shown) The device for clamping and guiding the rods consists of the body of the feeder 1, the cylinder 2 built into it, the piston with the rod 3, is integral with the wedge 4, interacts with the levers 5 of the cams 6. This cone is provided with a groove 7, which interacts with the latch 8, made in the form of a cylinder with a segment cut along the generatrix. The latch 8 is installed on the support 9, and the return spring 10 is installed on the snags 5. The drawing also shows the rod 11 and the crown 12. The cone is made of variable radius with cones 13-17. The device works as follows. In the extreme right position of the rod 3, the wedge 4 by the cone 13 interacts with the levers 5, while the cams 6 under the action of the spring 10 allow the rod to pass through And with the crown 12. The latch 8 translates from into readiness for fixation. The piston with the rod 3 and the wedge 4 is fed to the left, the guide 7 reaches the latch 8 which, under the action of a spring (not shown) rotates and connects the wedge 4 to the stop 9, the further movement of the wedge stops. The lever 5 interacts with the wedge 4 with a cone 17 and creates a centering hole for the rod 1 with cams 6, which allows it to withstand a predetermined direction when drilling. After drilling, wedge 4 p is released from latch 8 and is transferred, for example, to the extreme right position so that the cams b are dispersed and allow the clutches to pass through the hole. For clamping the rods, the wedge 4 is moved to the left position, the cone 17 interacts with the levers 5 when clamping the rod, and the cone 13 interacts with the levers 5 when clamping the coupling with the levers 5. The cone 14 and 16 shortens the length of the wedge 4 when the centering hole changes from diameter rod to the diameter of the coupling and at the same time reduce the angles of the cones 15 and 17, which improves the power characteristics of the clamp as a whole. The presence of a single cylinder in the shtang clamping device allows to simplify the design, and the cylinder location in the feeder body reduces the size of the device, which makes it possible to drill in the immediate vicinity of the production sidewalls, allows the device to be used when drilling holes and boreholes. working out. An apparatus for clamping and guiding the rods of a boring machine, including a cylinder, a piston with a rod, clamping cams with levers, and a latch, characterized in that, in order to reduce the dimensions, the rod is made with a wedge installed with the possibility of interacting with the levers of the jaws and the latch, at the same time the wedge is made with a variable angle, and the cylinder is fixed in the case of the feeder of the boring machine.
