Abstract

This invention relates to a lifting and transport machinery. The purpose of the invention is to improve performance. The gripping device for long items contains half-frames 1 and 2 (telescopically connected). U-shaped elements 4 and 5 and pick-up arms 6 are placed at the ends of the frame. At least on one half-frame there is a vertical corkscrew 8. The device is suspended from the crane hook by the ring 3, installed above the bag. The frame is moved by the hydraulic cylinder 10 to the required width. The catch arms are mounted by means of hydraulic cylinders 7 along the product package. The device is lowered until the corkscrew 8 enters the gap between the two packages. Hydraulic motors 9 are engaged. The device continues to descend. The corkscrew 8 expands the articles and creates a downward pulling force, facilitating the engagement of the grip. After the device has been sufficiently immersed, the catch arms 6 are turned by hydraulic cylinders 7 inside and come under the bag. Then, the U-shaped elements 4 and 5 are shifted by the hydraulic cylinder 10 and compressed the bag to a width that ensures its placement in the wagon 1 Cp. Of the file, 3 sludge.

(54) A gripping device for long products. (57) The invention relates to hoisting machinery. The purpose of the invention is the improvement of operational characteristics. The gripping device for long products contains half frames 1 and 2 (telescopically connected). U-shaped elements 4 and 5 and grab levers 6 are placed at the ends of the frames. At least one corkscrew has a vertical corkscrew 8. The device is suspended from the crane hook by the ring 3, mounted above the bag. The frame is moved apart by the hydraulic cylinder 10 to the required width. Grabbing levers are installed using hydraulic cylinders 7 along the product package. The device drops until the corkscrew 8 enters the gap between the two packets. The motors 9 turn on. The device continues to lower. Corkscrew 8 pushes the product and creates a pulling force directed downward, contributing to the immersion of the grip. After sufficient immersion of the device, the grab arms 6 are turned inward by the hydraulic cylinders 7 and enter under the package. Then the U-shaped elements 4 and 5 are shifted by the hydraulic cylinder 10 and compress the package to a width that does not ensure its packing in a car 1 s. P. f-ly, 3 ill.

Fie. 7

The invention οι is related to the elevation of transport engineering, in particular to lifting devices.

The purpose of the invention is the improvement of operational characteristics.

In FIG. 1 shows a gripper, general view; on fi; ·. 2 - - the moment of immersion of the gripper when taking the extreme package from the stack; in FIG. 3 - gripping device before lifting the taken package.

The gripping device comprises telescopically connected parts to the half frames 1 and 2, a ring 3, by which it is suspended from a crane hook. Each of the half-frames 1 and 2 is equipped with two U-shaped elements 4 and 5 and grab levers 6, driven by hydraulic cylinders 7. Corkscrews are installed along the struts 8. Rotated by hydraulic motors 9. Elements 4 and 5 together with half-frames I and 2 can be moved using hydraulic cylinder 10.

Nolurams 1 and 2 are connected to the ring 3 using rods 11.

To improve the possibility of getting into the gap between two long products, the grab arms are made with the possibility of free vertical movement.

The gripping device operates as follows.

The device is suspended from the crane hook by the ring 3 and mounted above the bag. In this case, the U-shaped elements 4 and 5 are moved apart by the hydraulic cylinder 10 to the required width. The gripping elements 6 are mounted by means of the hydraulic cylinder 7 to the position shown in FIG. 1, along the logs of the package. Then the device is lowered onto a stack of products so that the end of the rack with a corkscrew falls into the gap between the two packets. Hydrometers 9 are turned on. At the same time, the device continues to be lowered by the crane operator, so that the force of the gripping weight facilitates the introduction into the stack. In this case, the corkscrew 8, rotated by the hydraulic motor 9, pushes the logs of adjacent packages and simultaneously creates a pulling force directed downward, contributing to the immersion of the grip. After capturing sink into the pile to a sufficient depth includes hydraulic cylinders that turn inwards at 90 ^th podhvatnye levers 6, which come under the package. Then the hydraulic cylinder 10 is turned on to shift the U-shaped elements 4 and 5, which compress the package to a width that ensures its laying in the car.

Claims (2)

Claim 1. A gripping device for long products, comprising a frame made of two telescopically connected parts, each having a vertically arranged II shaped element each on its free end, rotatable around a vertical axis located within the horizontal dimensions of the Π-shaped elements, a pair of gripping arms, characterized in , what. in order to improve operational characteristics, it is equipped with at least one drive screw corkscrew element mounted on a U-shaped element in its plane from the outside of one of its racks parallel to it. 2.
