Abstract

The invention relates to the loading and transport of piece goods. The purpose of the invention is to improve the reliability of clamping the load. f6 It is provided with a more reliable securing of the load on the forklift and automatic adjustment of the magnitude of the pressing force in proportion to the weight of the cargo being processed. This is achieved by connecting the working cavities of the additional ram 8, the ram 7 and the ram 3 of the ram 2 through the distributor 15, allowing alternating plug cavities. The device can be used on vehicles as an automatic lock for piece goods. When the working medium is supplied, the additional power cylinder 8 acts on the clamp 7. When the force on the load is reached, which is proportional to its mass, the lifting of the carriage 1 with the load begins. 3 hp f-ly, 3 ill. (L

Description

1

j The invention relates to the loading and transportation of piece G1) chains in warehouses and in open areas and is intended to hold a load on a forklift when loading and moving,

The purpose of the invention is the new reliability of clamping the load.

FIG. 1 shows a forklift with a fork and clamp in the locked position; in fig. 2 - the same, clamping in the working position, the load is fixed; in fig. 3 - the same, a forklift with a vertical (clamped) load clamping mechanism.

The loader contains a carriage 1, a power cylinder 2 lifting it with a load chain 3 and a roller 4, a load clamping mechanism containing a rack 5 attached to the carriage 1 with the possibility of vertical movement, with a guy in the upper part for installing two shoulders 6. virnirnoy fastened at one end 7, and at the other - additional j: silt cylinder 8 (pressure) with a working-1 пол fixation cavities 9 and unfixed-10 .; The second end of the additional sludge cylinder 8 is hinged on the rack 5. The cavities of the additional power cylinder 8 are connected to the distributor 15 and the power cylinder 2 by pipelines 11-14, and the pipe 15 connects the distributor 15 to the hydraulic tank 16 (when using as a working fluid, liquid IKOCTH), in addition, a damper 17 is installed in the hydraulic track |

I Forklift works as follows

Before seizing the load, it is necessary to transfer the clamp 7 to the upper position. For this purpose, the distributor 15 is switched to the unlocked position, which ensures the flow of the working medium, for example, liquid, from the cylinder 2, through the power supply pipelines 13 and 11, into the cavity 10 of the additional power cylinder 8. At that, the fluid from the cavity 9 is displaced into pipelines 16. To fix the load, it is necessary to transfer the distributor 15 to the locking position, allowing the flow of fluid from the cylinder 2 to be reversed through pipelines 13 and 12 into the cavity 9 of the additional cylinder 8, and through pipelines 1 1 and

14 from the cavity 10 to the underwater tank 16. The flow of fluid continues until the clamp 7 touches the surface of the load located on the forks, after which the load is lifted to the transport position due to further pumping of the fluid into the power cylinder 2. The pressing force is determined by the ratio of diameters power cylinders 2 and B, the ratio of the arms of the arms of the lever 6 and the size of the load located on the forklift. When working with a vertical (clamping) clamping mechanism (FIG. 3), the loader approaches the load being processed and lowers the carriage with the stand: 5, the additional power cylinder 8 and the clamps 7 so that they are at the level of the load. The distributor 15 include in the position of fixation and lift the load to the desired height.

Depending on the type of gripping, the load is released from the load in the following order: the load is delivered to the destination and the distributor 15 is switched to the unlocking position, and there is some lowering of the load due to the flow of fluid from the power cylinder 2 into the cavity 10 If the lowering is not sufficient, then the movable carriage is additionally lowered. When the distributor 15 is in a neutral position, the channels are closed and the clamp remains in the position that it had when the distributor 15 was moved to the neutral position. The device is transferred to the neutral position when moving without cargo or when there is no need to fix the cargo on the load lifter.

The damper 17 smoothes the sharp pressure points in the fixation cavity of the additional power cylinder 8, which arise due to dynamic loads during transportation.

For handling goods with different dimensions of the rack 5 clamp 7 set. Newly mounted on the carriage 1 with the possibility of clamping at different heights.

The reliability of securing various weights is also provided by interchangeable clamps 7 with different configuration, corresponding to the shape of the load with different coefficient of friction and made of. elastic material.
