Description

The invention relates to lifting equipment and can be used to capture and tilt goods with loops in hard to reach places.

The purpose of the invention is to simplify the design and increase the reliability of the device.

Figure 1 shows the lifting device, a longitudinal section; ha. 2- distance A-A in FIG. one; on fig.Z - section bb in figure 1.

The load gripping device comprises a housing 1. a gripping pin 2 fixed therein, a lever 4 pivotally mounted on the housing on the axis 3, with a toothed sector of the bis on the head of the toothed sector 6 on its end. The casing 1 is provided with vertical guides 7 in which the rack rail 8. is in engagement with the gear sector 5. Link 9 is rigidly connected to the rail 8, mounted for movement in a vertical direction relative to the housing.

On link 9, it is pivotally mounted for a slot 10 with a protrusion 11, spring-loaded with spring 12 relative to housing 1. Link 9 and the brace 13 pivotally connected to it are used for connection by means of a sling 14 to a lifting mechanism. A removable handle 15 is mounted on the housing 1, which is fastened with a bayonet lock 16. In the housing 1, a recess 17 is made to secure the latch 10 with a protrusion 11. The gripping pin 2 is curved along an arc of a circle.

The device works as follows.

In the initial position, the link 9 is pressed by the spring 12 against the housing 1, the gripping lever 4 is in the extreme position, the latch 10 with its protrusion 11 interacts with the wall of the housing 1 (shown by a dash-dotted line), the rack 8 is recessed along the guides 7. With the help of a handle 15, a grip pin 2 is inserted into the load hole. By tensioning the sling 14 of the link 9, it moves upward and there is no gear rail 8 behind it, which

sector 5 rotates the gripping lever 4, which engages the gripping pin 2. At the same time, the latch

10 by a protrusion 11 slides along the wall of the housing 1 until the protrusion 11 falls into the recess 17 on the wall of the housing 1. The handle 1b is disconnected from the housing 1 Manufacturing - displacement and turning the load. For disengaging the device with a load, the latch 10 is moved upward to bring out the protrusion

11 out of the recess on the wall of the housing 1 Under the action of the spring 12, the link 9 moves downward along with the gear rack 8, which through the gear sector 5 rotates the gripping lever 4 to the extreme position. The catch pin 2 is pulled out of the load hole.

The invention provides for expanding the technological capabilities of the load gripping device by ensuring the capture of cargo in hard-to-reach places and its turning while increasing the reliability of cargo fixation, and also simplifies the design by eliminating parts that require precise manufacturing.
