Description

I

The image refers to load handling.

Known gripping devices containing a traverse with gripping levers mounted on it, provided with a lock ij or a lever-eccentric mechanism.

These devices require labor-intensive tracing and suspension of cargo.

Closest to the invention is a pick-up device for piece goods, containing a carrier beam, at one end of which a plate with a hole is fixed, and in the middle part there are gripping arms, whose upper arms are connected to each other by a spring-loaded eccentric lever mechanism J.

The disadvantages of this device are that the PCS is necessary to carry out manual operations when loading the cargo and reliability is not sufficient when transporting it.

The aim of the invention is to provide an automatic magnetically closing and opening gripping levers and preventing them from spontaneously opening when the cargo is transported.

To do this, in the proposed device, a double-arm lever and a pusher are installed on the beam, equipped with a spring-loaded lock that interacts with one of the arms of the double-arm lever.

FIG. 1 shows a general view of the described device; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a section b-B in FIG. one; in fig. 4 - device with a captured product.

Claims (3)

The gripping device consists of a carrier balk 1, in the middle part of which a lever grip 2 is installed, and at the end - a plate 3 with a hole. The beam 4 and the support plate 5 are also attached to the beam 1. A double-arm lever 6 and a clamp 7, interacting with the pusher 8, spring-loaded 9 are fixed on the upper surface of the beam. The clamp 7 is equipped with a spring 1O and is installed with the possibility of rotation G about axis 11. Lever grip 2 contains levers 12 and 13, mounted on axles 14 and 15 and connected by a spring 16. The upper arms of the levers are connected by a stoor 17 with a spring 18, forming together with the projections a and b of the levers 12 and 13 a leverage-ekaentric mechanism. Two shoulders lever 6, installed by the possibility of rotation about the axis 19, interacting with the lever-eccentric mechanism and lock 7 I The device operates as follows. : For 1 attachment of the gripping device to the product (for example, an artillery mine) plate 3 with a hole is put on the animated part of the product, and then lowered the gripping device so that the pushers 8 touch the support (desktop, soil, bottom of the crate). In this case, the pushers 8 move upwards and compress the springs of the pushers 8, at the same time they push the ends onto the lock 7 and rotate it around the axis 11. The lock 7 will compress the spring 1O of the lock and release the double shoulders lever 6. The double shoulders lever 6 will rotate around the action of the stopper 17 its axis 19 and release it from the tuck. The stopper 17 under the action of the spring 18 will move upwards and will release the arms of the levers 12 and 13 from the closure in places about. The levers 12 and 13 under the action of the spring 16 are rotated around the axes 14 and 15 and open. When the gripping device is further lowered, the shell of the product presses on the projections O of the levers 12, 13, the levers rotate around the axes 14 and 15 and the girth and shell of the product. Plate 5 should be located behind the product and secure it from axial lubrication. When the product is lifted using a lifting device or manually by the shackle 4, the double-shouldered lever 6 rotates around its axis 19, presses the hundred pores 17, the stopper 17 moves down, compresses the spring 18, and ends up between the arms of the arms 12 and 13 at the ends b, preventing their spontaneous; disclosure. At the moment of tearing off the pushers 8 of the gripping device from the support, the pushers under the action of the spring 9 move downwards and release the latch 7. The latch 54 7 rotates around the axis 11 under the action of the spring 10 and locks the double-armed lever 6. It will be necessary to lift the gripper from the product Means to put the product on the desktop, the ground or in the closure. In this case, the pushers 8 move upwards, compress the springs 9 and press the ends of the clamp 7 onto their shoulders and rotate it around the axis 11. The clamp 7 will compress the stem 10 and release the double-arm lever 6. Dual shoulders. the lever 6 under the action of the stopper 17 will rotate around its axis 19 and release it from pressing. The stopper 17 under the action of the spring 18 will move upwards and will release the bolts of the levers 12 and 13 from the closure at points S. The levers 12 and 13 are rotated around the axes 14 and 15 by the action of the spring 16 and open. Holding the double-arm lever 6 by the handle, it is necessary to withdraw the plate 5 of the gripping device, freeing the product from fixation from axial displacement; move the gripping device in the axial direction and withdraw the plate 3 with a hole from the ogival part of the product. Claims for piece goods, containing a carrier beam, at one end of which a plate with a hole is fixed, and in the middle part are gripping levers whose upper arms are interconnected by a spring-loaded lever-eccentric mechanism, characterized in that automatic closing and opening of the gripping levers and preventing their spontaneous opening during the transportation of cargo; a double-arm lever and a pusher fitted with a spring loaded are mounted on the beam th latch interacting with one of the arms of a two-armed lever Sources of information received into account in the examination 1.
