(54) ПОДАТЧИК ДЛЯ БУРИЛЬНЫХ МАШИН(54) FEEDER FOR DRILLING MACHINES

II

Изобретение относитс к области горной промышленности, в частности к податчикам дл бурильных машин.The invention relates to the field of the mining industry, in particular to feeders for boring machines.

Известен податчик дл бурильных машин, включаюший подаюший механизм, направл ющую балку, гидроцилиндр с удвоителем хода, узел нат жени цепей 1.A known feeder for boring machines, including a feeding mechanism, a guide beam, a hydraulic cylinder with a stroke doubler, a tensioning unit for chains 1.

Его недостатком вл етс сложность конструкции.Its disadvantage is the complexity of the design.

Наиболее близким по технической сущности и достигаемому результату вл етс податчик дл бурильных машин, включающий раму с салазками, силовой цилиндр с поршнем и штоком, закрепленным на торце рамы, траверсу узла нат жени гибких звеньев удвоител хода податчика 2.The closest in technical essence and the achieved result is a feeder for boring machines, including a frame with a sled, a power cylinder with a piston and a rod fixed on the end of the frame, the yoke of the tension unit of the flexible links of the feeder 2 stroke.

Его недостатком вл етс сложность конструкции и большие габариты податчика.Its disadvantage is the design complexity and large size of the feeder.

Цель изобретени - упрощение конструкции и уменьшение габаритов податчика.The purpose of the invention is to simplify the design and reduce the size of the feeder.

Дл достижени указанной цели узел наг жени гибких звеньев выполнен в виде уплотн ющего поршн , который установлен в торцовой части силового цилиндра с возможностью осевого смещени , при этом траверса удвоител хода имеет направл ющие ролики и размещена на уплотн ющем поршне.To achieve this goal, the flexible links inflator assembly is made in the form of a sealing piston, which is installed in the front part of the power cylinder with the possibility of axial displacement, while the doubler yoke has guide rollers and is placed on the sealing piston.

Кроме того, на уплотн ющем поршне выполнена кольцева проточка, в которой вмонтирована разрезна фрикционна втул5 ка, закрепленна на силовом цилиндре податчика .In addition, an annular groove is made on the sealing piston, in which the spindle has a friction sleeve mounted on the power cylinder of the feeder.

На фиг. 1 показан податчик, вид сбоку; на фиг. 2 - вид А на фиг. 1; на фиг. 3 - сечение на фиг. 1.FIG. 1 shows a feeder, side view; in fig. 2 is a view A of FIG. one; in fig. 3 is a sectional view in FIG. one.

)0 Податчик имеет несущую раму 1, по верхним направл ющим которой перемещаютс салазки 2, на которых крепитс бурильна машина 3. Внутри рамы расположен силовой цилиндр 4.) 0 The feeder has a carrier frame 1, along the upper guides of which the carrier 2 moves, on which the boring machine 3 is mounted. Inside the frame there is a power cylinder 4.

Claims

15, an axially movable piston 5 is installed, sealing the space between the cylinder and the rod. A piston 5 is rigidly attached to the end of the piston 5 leaving the cylinder, on which axes the guide rollers 7 of the travel doubler and the support rollers 8 are installed. The beam 9 with the guide rollers 10 is also attached to the blind bottom of the other end of the cylinder 4 mounted in the flange 12 of the carrier frame 1, and the body of the power cylinder 4 is mounted on the support rollers 8 in the lower frame guides 13 with the possibility of longitudinal movement. The piston 5 on the outer surface has a groove 14. The piston 5 from falling out of the cylinder 4 limits the opening of the friction sleeve 15 installed in the annular groove 14 and fixed with its collar in the groove of the cylinder body 4. The sleeve 15 has a groove with a clamp ring 16 installed in it, creating the force of pressing the sleeves to the surface of the groove 14 on the piston 5. The stroke doubler system contains the working 17 and single 18 branches of flexible links (cables or chains) that bend around the guide rollers 7 and 10 on the cross-arms 6 and 9, also bending around the guide 19 on the slide 2 and with its ends secured to the frame 1. The feeder operates as follows. The working fluid supplied under pressure into the cylinder 4 creates a force that moves the cylinder and the slide connected to it by means of branches 17 and 18 in one direction or the other. 2 with a drilling machine. 3. Tension of the flexible links of the stroke doubler occurs automatically as follows. The working fluid entering the cylinder's cylinder cavity creates an ejector force on the piston 5, which under the action of this force moves within the free part of the groove 14 along with the crosshead 6 and the guide rollers 7 on it until the flexible doubler links are fully tensioned. After pulling the flexible links of the doubler stroke, the body of the cylinder 4 begins to move with the rollers 10 and move the slide with the drill mask 3 away from the bottom. When working at the bottom of the piston 5 inside the cylinder, and therefore weakening the tension of the flexible links, friction forces created by the ring 16 and rubber seals of the piston 5 in the cylinder and the pin 11 in this piston will prevent. The application of the proposed tensioning unit of the flexible links of the stroke doubler simplifies the design and manufacturability of the feeder. It reduces its dimensions due to the absence of additional parts for tensioning the cable. In addition, additional time costs during repair for disassembly and assembly of the tensioner are eliminated. Claim 1. A feeder for drilling machines, including a frame with a sled, a power cylinder with a pistol and a brush fixed at the end of the frame, the yoke of the tensioner of the flexible link of the feeder's doubler stroke, characterized in that, in order to simplify the design and reduce the dimensions of the feeder, the tension unit of flexible links is made in the form of a sealing ring, which is installed in the end part of the power cylinder with the possibility of axial displacement, while the doubler yoke has guide rollers and is placed on the sealing lip. schne. 2. A feeder according to claim 1. characterized in that an annular groove is made on the sealing body, in which a friction sleeve is mounted, mounted on the power cylinder of the feeder.
