RU196084U1 - SINGLE GRIP - Google Patents

Abstract

A single-rope grab refers to devices for excavating, loosening or moving soil manually from ponds, wells and septic tanks. This model of a grab with automatic closing of the jaws, for lifting bottom, loose sediments, by means of small-scale mechanization of the lifting device (winch or manually), in places with limited access to heavy equipment, such as a garden with buildings. The work of this grapple is as follows: to simplify the work, one cable is used. The lock 5 and the additional loop 4 on the cable 1 fixes the jaw in the open state before contact with the ground. After contact with the ground, the cable 1 and the loop 4 weaken and release the lock 5, which, under the influence of gravity, moves to the side. The loop 4 flies from the lock 5, the cable 1 freely pulls the roller 3 up and closes the jaw, then the ground rises. To unload the grab, you need to pick up the loop 4 for the lock 5 and the jaw will open.

Description

A single-rope grab for lifting bottom, loose sediments, by means of small-scale mechanization of a lifting device (winch or manually), in places with limited access to equipment, such as a personal plot with buildings.

The prior art.

The utility model relates to devices for excavation, loosening or moving soil manually from ponds, wells and septic tanks. International classifications:

В66С 3/10 automatically opening when lowering the grab to the place of unloading of material.

B66C 3/06 grabs driven by a single rope or chain.

Consider a similar single-rope grab (Fig 3.). Utility Model Patent RU 103102 U1, published March 27, 2011 bull. 9.

1. A single-rope grab containing the upper and lower traverses, two jaws connected by a hinge to the lower traverse and suspended by rods to the upper traverse, an earring for hanging from the hook of the lifting device, a lock for coupling with the lower traverse connected through the block chain block to the upper traverse, a rope passed by the first end through the chain hoist and connected to the earring, characterized in that at least one block is attached to the earring, and the rope covers this block and is connected by the second end to the upper beam .

2. A single-rope grab according to claim 1, characterized in that at least two blocks are attached to the earring and at least one block is mounted on the upper crosshead, the rope alternately covering one of the earring blocks and one of the upper crosshead blocks.

The disclosure of this grab is controlled by the clutch lock with the lower traverse, connected through the block chain hoist to the upper traverse, which complicates the design, increases weight, makes it impossible to use the grapple in conditions of small mechanization of the lifting device (winch or manually).

Disclosure of a utility model.

The purpose of the utility model is to simplify the design for working with small hoisting machinery (winch or manually) on unequipped sites, such as a garden with limited access for equipment. In wells, septic tanks and ponds. This goal is achieved by reducing the weight due to the structure of the jaws and suspension, with the exception of the clutch lock with the lower traverse connected through the block chain block with the upper traverse and the earrings 12 for hanging a load-lifting device to the hook.

Thus, the cable 1 from the lifting device passes through the eyelet on the axis of the suspensions 2, the lower roller 3 is attached to the axis of the suspensions. The loop of the cable 4, to open and hold the grapple open, clings to the lock 5. The jaws 6 are connected at one end to the roller 3, the other through the suspensions 7 to the axis of the suspensions 2. The lock 5 is on the same axis with the suspensions 7 in the upper part of the grab.

Description of the drawings.

In FIG. 1 shows a grab in a closed state. The cable 1 attached to the lifting device passes through the eyelet of the axis of the suspensions 2, the roller 3 attached to the axis of the suspensions 2, holds the grab in the closed state. In FIG. 2 shows a grab in an open state. The cable 1, attached to the lifting device, is attached by a loop 4 to the lock 5, holds the grab in the open state.

In FIG. Figure 3 shows a single-rope grab (Patent for utility model RU 103102 U1, published March 27, 2011, bull. 9. Based on the general idea of this design, the presented version of the grab has been developed. Contains: an earring for hanging a hoisting device 12 from the hook, cable 10.1; 10 , 2; an eye in the upper traverse 11; a lock for engaging with the lower traverse 9; the latch of the lock 5.

Implementation of a utility model.

The single-rope grab during excavation, to simplify the work, is equipped with a lock 5 and an additional loop 4 on the cable 1, which allows to fix the jaws in the open state before contact with the ground. After contact with the ground, the cable 1 and the loop 4 weaken and release the lock 5, which, under the influence of gravity, moves to the side. The loop 4 flies off the lock 5, the cable 1 freely pulls the roller 3 up and closes the jaw 6, the ground rises. To unload the grab, you need to pick up the loop 4 for the lock 5, the jaw 6 will open.
