(54) КАБША МОСТОВОГО КРАНА(54) PANEL CRUPSE

Изобретение относитс к грузоподъемным машинам, в частности, к . : кабинам кранов.The invention relates to lifting machines, in particular to : cabins cranes.

Известна кабина крана, содержаща каркас и обгаивку несущего стекла, защитный экран, расположенный параллельно стеклам каоаны и имеющий роJлики , установленные с возможностью перемещени по направл ющим.A crane cabin is known, comprising a skeleton and a hauling of carrying glass, a protective screen located parallel to the glasses of the canal and having rim mounted for movement along guides.

Эта кабина не исключает отрица- тельного действи на балку крана, . вызванного, моментом от массы кабины , и св занного с ним по влени усталостных трегщн в месте сопр жени главной и концевой балок/Г/7.This cabin does not exclude the negative effect on the crane beam,. caused by the moment from the weight of the cabin, and the associated occurrence of fatigue traction at the interface between the main and end beams / G / 7.

Известна так же кабина мостового KJjaHa, со ру- тца каркас с панел ми и остеклением и элементы к крану 2..The KJjaHa bridge cabin is also known, with a rotor frame with panels and glazing and elements for a crane 2 ..

Жесткое крепление кабины с главной балкой с помощью швеллеров вызывает действие момента на главную , балку в месте сопр жени с концевой балкой, что снижает надежностьThe rigid fastening of the cabin with the main beam with the help of channels causes the moment to act on the main beam at the interface with the end beam, which reduces reliability

этого узла, и обуславливает действие вибрационных нагрузок на маииниста и оборудованне в кабине при работе крана.This node, and causes the action of vibration loads on the driver and equipment in the cabin when the crane is operating.

Цель изобретени - повьше ше удобства работы машиниста и эффективности гашени вибрации.The purpose of the invention is to improve the convenience of the driver and the effectiveness of damping vibration.

.Поставлеййа цель достигаетс тем, что элементы креплени содержат стержень со сферическими itmnato ми на концах, установленными в сферических подп тниках, один из кото- , рых жестко закреплен на главной балке крана, а второй прикреплен через резинометаллическиз амортизатор к The delivery goal is achieved by the fact that the fastener elements contain a rod with spherical itnatoes at the ends installed in spherical baffles, one of which is rigidly fixed on the main beam of the crane, and the second is attached to

FIG. 1 shows the cab of a bridge crane, the general view of FIG. /. (The same, frontal view in Fig. 3, node 1 in Fig. 2; nv Fig. 4 - node I ne Fig. 1 $ in Fig. 5 - node W in Fig. I. Cabin 1 of an overhead crane with main beams 2 and end beams 3 contains fastening elements, containing a rod 4 with spherical spikes 5, 6, the first of which is mounted in a spherical latch 7, rigidly connected to the head beam, and the second one in a spherical thrust 8, connected through a rubber-metal shock absorber 9 to the frame of the cabin , performed in a known manner and therefore not shown in Fig. I, 2, and two rods 10, II, made equally in and consisting of 1UTOKOB 12, washers 13 and elastic elements 14, for example rubber, placed in housing 15 with covers 16, secured with cylindrical hinges 17 and brackets 18 from one side to the end rail, and from the other to the cab frame. works as follows. When a bridge crane is moving along crane tracks with various imperfections and when unloading and seizing goods, the torsional vibrations of the main beam 2 caused by these sources of vibrations will not cause the cab 1 to swing. prov rachivats relatively cab due spherical ischpu 5, 6 and of the same sub-clause contours of the pendulum 7, 8. Therefore, the possible deviation of the cab 1 from the vertical position when starting and stopping the overhead crane will not cause twisting of the main beam. The vertical vibrated metal structures of the bridge crane will be extinguished with the help of a rubber-metal shock absorber 9 and elastic elements 14, and various angular elements to the knives with the help of elastic elements 14 due to their ability to absorb vibrational energy. Installations of cylindrical hinges 17 in the perpendicular-plane planes 17 provide for undisturbed vibrations along and across the movement of the crane bridge. Such mounting of the cabin allows to eliminate the tricky effect of the weight of the cabin on the reliability of the node connecting the main and end beams due to the hinged connection of the cabin to the main and end beams using rods with spherical studs and drafts with two cylindrical hinges. The installation of a rubber-metal shock absorber between the cab and the undercarriage and the elastic elements in the bellows reduces the level of vibrations affecting the driver and equipment in the cab. Claims of the overhead crane cabin, containing a frame with panels and glazing and fastening elements to the crane, characterized in that, in order to increase the operator's comfort and vibration damping, the fastening elements comprise a rod with spherical studs at the ends installed in spherical supports ticks, one of which is rigidly fixed on the main beam of the crane, and a friend is attached through a rubber-metal shock absorber to the frame of the cabin, and .t gi with elastic elements connecting the cabin with the end bars w cylindrical hinges, with the axes of the hinges of each tie arranged in mutually perpendicular planes.
