(54) ГРУЗОПОДЪЕМНАЯ ТРАВЕРСА(54) LOADING TRAILERS

II

Изобретение относитс к подъемно-транспортному машиностроению, а именно к устройствам дл подъема и перемещени грузов в помещени х, ограниченных по высоте .The invention relates to a lifting and transport machinery, namely, devices for lifting and moving loads in height-restricted rooms.

Известна грузоподъемна траверса, содержаща навешиваемую на крюк грузоподъемного механизма несущую балку с захватными органами и осью, взаимодействующей с крюком и закрепленной в средней .части балки ниже центра ее т жести 1.A lifting beam is known, containing a carrier beam with a gripping body and an axis interacting with the hook and fixed in the middle part of the beam below the center of its weight 1, which is hung on the hook of the lifting mechanism.

Недостаток известного устройства - значительный габарит по высоте.A disadvantage of the known device is a significant overall height.

Целью изобретени вл етс повышение эффективности работы траверсы в помещени х , ограниченных по высоте, путем размещени крюковой обоймы внутри балки.The aim of the invention is to increase the efficiency of the traverse in rooms with limited height by placing the hook cage inside the beam.

Указанна цель достигаетс тем, что траверса снабжена установленным на верхней горизонтальной поверхности балки диском с направл ющими ребрами и закрепленным к стенке балки приспособлением дл перемещени оси, содержащим шарнирно соединенные между собой с возможностью ограниченного поворота руко тку, несущую противовес, и рычаги, щарнирно соединенные с упом нутой осью,а направ л ющие ребра выполнены в .верхней части с заходными участками.This goal is achieved by the fact that the yoke is provided with a disk mounted on the upper horizontal surface of the beam with guiding ribs and fixed to the wall of the beam with an axle displacement device containing pivotally interconnected with a possibility of limited rotation of the counterweight, and levers that are pivotally connected to the said axis, and the guide ribs are made in the upper part with lead-in sections.

Кроме того, с целью обеспечени возможности поворота траверсы в горизонтальной плоскости, диск снабжен роликами, взаимодействующими с верхней горизонталь5 ной поверхностью балки.In addition, in order to provide the possibility of turning the crosspiece in the horizontal plane, the disk is provided with rollers that interact with the upper horizontal surface of the beam.

Claims

The lifting beam includes a carrying beam 1, on the upper horizontal surface of which there is a round hole in which the disk 2 is installed with a slot for the hook yoke. The disk is equipped with four guide ribs 3, which are drawn in the upper part with inclined lead-in sections and located on both sides of the hook-ring earrings, as well as guide rollers 4, which encircle the traverse rotation in the 20 horizontal plane relative to the disk. At the ends of the beam 1 is fixed to. gripping bodies 5. In the middle part of the beam, below the center of its gravity, is the axis 6 for hanging the yoke on the hook of the lifting mechanism, which is pivotally connected to pi-iiaraMH 7, spaced along the walls of the beam and fixed to the latter through an axis 8 rigidly connected to the handle 9 , bearing counterweight 10. The swivel connection of the levers with the handle ensures their mutual rotation limited by the stops 11 and 12. The limiting positions of the lever 7 are limited by the stops 13 and 14. The traverse works as follows. Before hanging the crane hook on the handle 9 standing on the frame, the traverse rotates clockwise, and the interacting stops 11 and 12 rotate the lever 7 until it comes into contact with the stop 14, as a result of which the axis 6 moves to the left, making way for the passage of the crane hook 15. The hook is lowered in such a way that the earrings 16 of the hook clip are inserted between the guide ribs 3. In this case, the clip enters the disc slot, which is facilitated by the presence of inclined approach portions on the ribs. The lowering of the hook continues until the shed of the hook is below axis b. Then the knob 9 is turned clockwise, the stops 1 and 12 rotate the lever 7 until it touches the stop. rum 13, and axis 6 is in the hook throat. When the hook is lifted, the latter hooks onto the axis in and lifts the beam 1. Despite the fact that the center of gravity of the bar is located above its support point on the hook 15, it does not tilt because the disc 2 prevents this, the ribs 3 of which rest on hook holder The possibility of free rotation of the crossbeam with a load relative to the disk with the holder is guaranteed by the commonly used {hinge joint, the hook with the clip and the presence of guide rollers 4. The device for hanging the crosshead on the hook of the lifting mechanism can be lifted It is also not in the form of a rod 17, missed. Through the beams 1 of the sleeve 18 fixed to the bottom. For secure: the rod in the working position of the crossbar can be equipped with a latch 19, passed through the proupzhny 20. The proposed invention significantly reduces the size of the device in height, expands the possibilities of work with loads in rooms whose height is limited. Claim 1. Load-carrying beam, containing a carrier beam with a gripping body and an axis interacting with the hook and fixed in the middle part of the beam below its center of gravity, which is attached to the hook and fixed in the middle part of the beam, in order to increase its efficiency in the room x, limited in height, by placing the hook cage inside the beam, the traverse is fitted with a disk mounted on the upper horizontal surface of the beam with guide edges and fixed to the wall of the beam to move the axis containing the hinge interconnected with the possibility of limited rotation of the handle carrying the counterweight, and the levers hinged connected with the said axis, and the guiding ribs, and made in the upper part with lead-in sections. .

2. The traverse of clause 1, distinguished from the JSM that, in order to provide the possibility of. gate traverse in the horizontal plane, the disk is provided with rollers, interacting with the upper horizontal surface of the beam.
