(54) ПОГРУЗЧИК(54) LOADER

II

Изобретение относитс к погрузочному оборудованию, в частности к погрузчикам, примен емым дл штабелировани грузов на складах.The invention relates to loading equipment, in particular to loaders used to stack goods in warehouses.

Известен погрузчик, содержащий тележку с установленными на ней грузозахватом и подвижными в поперечном направлении продольными балками с приводом их перемещени и колесами на свободных концах 1.A loader is known, comprising a carriage with a load gripper mounted on it and transversely movable longitudinal beams with a drive for their movement and wheels at the free ends 1.

Недостатком известного погрузчика вл етс то, что рассто ние между его продольными балками посто нно, а поскольку щирина поддона с грузом не должна превыщать это рассто ние, то при использовании поддонов больщой щирины необходимо иметь погрузчики с больщим рассто нием между продольными балками. В том случае, если дл погрузки как узких, так и щироких поддонов на складе используетс один погрузчик , то необходимо, чтобь рассто ние между его продольными балками было достаточно дл погрузки и разгрузки грузов на поддонах наибольшей щирины, т. е. должно быть велико. Это вызывает необходимость устанавливать все стеллажи на большом рассто нии один от другого, что обусловливает неэффективность использовани площади склада.The disadvantage of the known loader is that the distance between its longitudinal beams is constant, and since the width of the pallet with the load must not exceed this distance, then when using large width pallets it is necessary to have loaders with a large distance between the longitudinal beams. In the event that a single loader is used for loading both narrow and wide pallets in a warehouse, it is necessary that the distance between its longitudinal beams be sufficient for loading and unloading cargoes on pallets with the greatest width, i.e., should be large. This makes it necessary to install all the racks at a large distance from one another, which makes it inefficient to use the warehouse space.

Цель изобретени - увеличение срока службы.The purpose of the invention is to increase the service life.

Поставленна цель достигаетс тем, что погрузчик снабжен гидродомкратами, установленными на тележке со смещением относительно центра т жести погрузчика в сторону колес продольной балки.The goal is achieved by the fact that the loader is equipped with hydraulic jacks mounted on a trolley with an offset from the center of gravity of the loader body towards the wheels of the longitudinal beam.

На фиг. 1 изображен погрузчик, вид сбоку; на фиг. 2 - то же, вид сверху. ,Q Погрузчик содержит тележку 1, снабженную поперечным несущим элементом 2, в котором установлены подвижно в поперечном направлении продольные балки 3 с колесами 4 на свободных концах.FIG. 1 shows a loader, side view; in fig. 2 - the same, top view. , Q The loader contains a carriage 1, provided with a transverse carrier element 2, in which longitudinal beams 3 with wheels 4 at free ends are mounted movably in the transverse direction.

Устройство дл перемещени продольных балок содержит гидроцилиндры, закрепленные на поперечном несущем элементе и размещенные внутри него. Штоки гидроцилиндров соединены с продольными балками .The device for moving the longitudinal beams contains hydraulic cylinders mounted on the transverse bearing element and placed inside it. Rods of hydraulic cylinders are connected with longitudinal beams.

Claims

The loader has a load-carrying fork 20 grip 5, connected to a power mechanism. The power mechanism contains a hydraulic cylinder 6. The plunger 7 of the hydraulic cylinder 6 is connected by a chain transmission 8 with a claw 5. The hydraulic cylinder 6 ycTaiiOBJioi on a lifting frame 9 fixed on the trolley 1. The trolley is mounted on hydraulic jacks 10, mounted with offset relative to the center of the loader's body in the HV wheels 4 longitudinal beams 3. The center of the body of the loaders of the type described is, as a rule, on a lifting frame. Hydrojacks are fixedly fixed Neither the transverse carrier element 2 of the trolley 1 between the longitudinal beams 3 and the form of hydraulic cylinders, on the rods of which the supports 11 are fixed the handle 12 for controlling the hydraulic jacks 10, the handle 13 for controlling the hydraulic cylinder 6 and the handle 14 for controlling the hydraulic cylinders for displacing the longitudinal beams. The loader works as follows. When it is necessary to extend the longitudinal beams, for example, in the case of unloading cars, the worker servicing the forklift rotates the handle 12. In this case, the working fluid under pressure from the tank (not shown) is fed into the hydraulic jacks 10, as a result of which the supports 11 extend. loader and vyvepshivayutsya wheels 4. Then the handle 12 is rotated in it. The back position, with the result that the working fluid is locked in the cavity of hydraulic jacks and the lifting of the front part of the loader stops. After that, the handle 14 is rotated. In this case, the working fluid under pressure is supplied to the hydraulic cylinders 5, as a result of which their rods are pushed and the longitudinal beams connected with them are moved apart to the distance necessary for the loader to move unhindered to the car. The handle 14 is then brought to the neutral position, and the extension of the longitudinal beams is stopped. When extending the longitudinal beams of the front part of the loader lifted by hydraulic jacks 10, the wheels 4 do not touch the floor of the warehouse, therefore the loader does not turn around and the wheels do not wear out. After extending the longitudinal beams, the handle 12 is rotated to the position where the cavities of the hydraulic jacks are connected to the tank, as a result of which the working fluid is drained from the cavity of the hydraulic jacks into the tank, the supports are raised and come out of contact with the warehouse floor, the wheels 4 are lowered to the warehouse floor . Then the handle 13 is turned. The working fluid under pressure is supplied under the plunger of the hydraulic cylinder 6, as a result of which the plunger rises, rises and the gripper 5 connected to it by a chain drive. The loader manually rolls towards the car so that the gripper is under the pallet with the load. Then, as previously described, the grab is raised with the pallet on it. The handle 13 rotates to the neutral position, with the result that the lifting of the gripping is stopped. The loader manually rolls away from the car. The handle 13 is rotated to a position in which the cavity of the hydraulic cylinder 6 is connected to the tank, as a result of which the working fluid from the hydraulic cylinder is drained into the tank and the cargo is lowered between the longitudinal looms of the loader to the warehouse floor. The loader rolls over to the car after the next load. In some cases, if, for example, the loader is used in a warehouse with a small distance between the racks, the longitudinal beams need to be shifted. To do this, as described earlier, the wheels 4 are first illuminated with the help of hydraulic jacks 10, and then the longitudinal beams are shifted with the help of hydraulic cylinders 5. The use of the proposed loader will significantly reduce the laboriousness of loading and unloading works, free up loaders, improve safety, and raise the culture of production. Claims of the Invention t of the loader in the direction of the wheels of the longitudinal beams. Sources of information taken into account in the examination 1.
