(54) УГОЛЬНЫЙ СТРУГ(54) COAL STRING

1one

Изобретение относитс к технике добычи угл подземным способом, а именно к выемке угл на полную мощность пласта с помощью стругов.The invention relates to a coal mining technique, in particular, to excavating coal at full capacity using a plow.

Известна стругова установка, вклю чаюша конвейер, нижний и верхний исполнительные органы с разделенными направл ющими. Верхний исполнительный орган выполнен в виде консольной балки, на конце которой размещена рез цова головка. Нижний и верхний исполнительные органы подсоединены к различнь ветв м бесконечной т говой цепи, позвол ющим исполнительным органам двигатьс в разные стороны и разрушать нижнюю и верхнюю пачки угл 1.The plow installation is known, including a conveyor belt, lower and upper executive bodies with divided guides. The upper actuator is designed as a cantilever beam, at the end of which a cutting head is placed. The lower and upper actuators are connected to different branches of the endless traction chain, allowing the actuators to move in different directions and destroy the lower and upper bundles of coal 1.

Недостатком указанного угольного струга вл етс недостаточный диапазон регулировки верхнего исполнительнего органа.The disadvantage of this coal plow is the insufficient adjustment range of the upper actuator.

Наиболее близким техническим решением к предлагаемому изобретению вл етс угольный стругу включающий раму , резцовую головку, рычаг и т гу, образующих шарнирный четырхзвенник и упругий силовой элемент. Упругий силовой элемент, выполненный в виде рессор , прижимает резцовую головку к кровле пласта 2.The closest technical solution to the present invention is a coal jet comprising a frame, a cutting head, a lever, and a rod, forming a hinged four-bearing and elastic force element. Elastic force element, made in the form of springs, presses the cutting head to the roof of the reservoir 2.

Недостатком этого струга вл етс незначительна длина рычага, а следовательно , и рессор, а также достаточный диапазон регулировки резцовой головки по высоте.The disadvantage of this plow is the insignificant length of the lever, and hence the springs, as well as a sufficient range of adjustment of the cutting head in height.

Увеличить длину рессор при небольшой ширине призабойного пространства невозможно.To increase the length of the springs with a small width of the bottomhole space is impossible.

Целью изобретени вл етс увеличение диапазона регулировки резцовой головки по высоте.The aim of the invention is to increase the range of adjustment of the cutting head in height.

Это достигаетс тем, что упругий Силовой элемент выполнен в виде торсионного вала, размещенного в полой оси шарнирного четырехзвенника и снабженного элементами креплени с рамой и рычагом.This is achieved by the fact that the elastic force element is made in the form of a torsion shaft placed in the hollow axis of the hinge four-bearing and equipped with fastening elements with a frame and a lever.

На фиг. 1 изображен угольный .струг общий вид; на фиг. 2 - вид по стрелке А на фиг. 1; на фиг. 3 - схема соединени торсионного вала с рамой и рычагом .FIG. 1 depicts a coal. General view; in fig. 2 is a view along arrow A in FIG. one; in fig. 3 is a diagram of the connection of the torsion shaft with the frame and the lever.

Угольный струг состоит из рамы 1, рычаха 2, шарнирно соединенного с рамой 1 и резцовой головкой 3 с помощью оси 4 и полых осей 5.Coal plow consists of a frame 1, levers 2, pivotally connected to frame 1 and a cutting head 3 with the help of axis 4 and hollow axles 5.

Claims

In order to maintain a constant position of the incisors when the height of the plow is varied, the incisal head 3 and frame i are articulated by a link 6. To ensure a constant pressing of the cutting head to the roof of the reservoir on frame 1 in hollow axles 5, a torsion shaft 7 is placed, one end connected by means of splines to frame 1, and the second end to lever 2 by means of splined coupling half couplings 8, 9 and muffs You are 10, for fixing the torsion shaft, after being twisted and with the necessary preliminary effort, the coupling half 8 has teeth to engage with the pawl 11 mounted on frame 1. Ski 12 is intended to support the cutting head on the roof of the formation. The frame 1 of the coal plow is connected to the chord by a branch 13 of the chain, and a second pillar 14 to the lower branch 15 of the chain. Preliminary twisting of the shaft torso is performed as follows. With the help of a jack, the cutting head is lowered, which rotates the lever, and through the coupling halves 8, 9 and the coupling 10 tightens the torsion shaft. On the coupling half 8 there is a scale that is calibrated on the force in kilograms. When the necessary force is reached, the cutting of the cutting head stops. Then, the torsion shaft is fixed with the pawl 11 and the coupling half with the teeth 8. The splined coupling 10 disengages, lifts the cutting head to the top of the reservoir and the coupling 10 connects to the initial position. Then the pawl 11 is removed and the plow is ready for operation; The plow works as follows. The plow is pulled along the bottom with the help of the upper branch 13 of the chain; the cutting head removes the chips from the upper pack of the formation. The second plow 14, moving in the opposite direction with the help of the lower branch of the chain 15, removes the coal chips from the lower layer of the formation and loads onto the conveyor. The middle layer of formation, cut at the top and bottom, self-collapses on the conveyor. During excavation, the incisal angle of the holoek 3 by ski 12 with the aid of a torsion shaft is constantly pressed to the top of the seam. When the thickness of the layer changes, the cutting head removes coal chips from the roof without leaving dryness. Ski 12 can change its position relative to the upper cutters. To eliminate rubbing, reverse cutters that do not participate in coal mining are retracted from both the bottom and the roof. The implementation of the elastic element in the form of a torsion shaft, placed in the hollow axis of the hinge, increases the range of adjustment of the plow twice, reduces its dimensions and makes the adjustment of the pressing force easy. Claim Coal Plow including frame, cutter head, lever, and tie rod forming a shaft; double-sided link and an elastic FORCE element, characterized in that, in order to increase the adjustment range of the cutter head in height, the elastic force element is designed as a torsion shaft, placed a hollow ball spherical four-ring and fitted with fasteners with a frame and a lever.
