Description

Изобретение относитс к подъемнотранспортным устройствам и может быть использовано в угольной и горнорудной промышпешюст х.The invention relates to lifting devices and can be used in the coal and mining industries.

Наиболее близким техническим решением из известных вл етс подъемна установка, содержаща подъемные сосуды , привод, отклон ющие шкивы и выполненный с канавками барабан, на обеих половинах которого запасованы ветви гибкого т гового органа с уравнительными механизмами на концах соединенных с подъемными сосудами .The closest technical solution of the known ones is a lifting installation containing lifting vessels, a drive, deflecting pulleys and a drum with grooves, on both halves of which the branches of a flexible traction body with equalizing mechanisms at the ends connected to the lifting vessels are stored.

Однако такое устройство имеет сравнительно невысокую надежность - возможно проскальзывание гибкого т гового органа на барабане.However, such a device has a relatively low reliability - it is possible that the flexible traction organ slips on the drum.

Целью изобретени вл етс повышение надежности путем увеличени сцеплени гибкого т гового органа с барабаном.The aim of the invention is to increase reliability by increasing the adhesion of the flexible rod to the drum.

Это достигаетс тем, что канавки o6ei половин барабана нарезаны в одном направлении , а навивка каждой ветви гибкого т гового органа выполнена с посто нным This is achieved by the fact that the grooves o6ei of the drum halves are cut in one direction, and the winding of each branch of the flexible traction member is made constant.

Claims

The lifting device contains a drum 1 with spiral strands for fivka, for example, two ropes 2 and 3, a drive 4, a braking system 5, a control system 6. The ropes 2 and 3 are wound at least one and a half turns on the drum, then both ends of each rope are thrown over scraper pulleys 7, escaping branches 8 are connected in pairs with vessel 9, and incoming branches 1O - with vessel 11. The device operates as follows. When winding the lower ends of the rope 10 (oncoming branches), vessel 11 rises, while the upper ends 8 (running branches) wind off from drum and vessel 9 onycKaeTCH. At the same time, the friction turns of both ropes move along forming the drum. When the drum is rotated in the opposite direction, the reverse process of winding and winding the ropes occurs, while the movement of the turns of friction along the drum's generator is also carried out in the opposite direction. Thus, the entire length of the rope is constantly in operation. When each vessel is suspended on one end of the rope, the economy of length is obvious and significant, while using several cables on a lifting installation, saving in rope is achieved by decreasing them. (t diameters per PG, i.e., od --- W where — diameter of a rope during a single-rope rise, diameter of a rope during a multi-rope rise, k -number of ropes. Invention formula A lifting installation containing lifting vessels, a drive, deflecting pulleys and a drum made with grooves on which both branches have flexible branches of the traction organ with equalizing mechanisms at the ends connected to the hoisting ones, characterized in that, in order to increase reliability by increasing the coupling of the flexotra organ to the drum. floors the drum is cut in one direction, and the winding of each branch of a flexible traction body is made with a constant number of turns of friction, defined by the dependencies:., 5 where M is the coefficient of friction between the rope and the winding surface of the drum of ropes hung on C is relative the weight of the rope to the end load; tt is the safety factor for non-penetration.
