Abstract

Usage: the invention relates to the field of material handling equipment. SUMMARY OF THE INVENTION: The load gripping device comprises a hollow body in which a frame is mounted on the Novorotnaya sleeve. The load gripping device provides unambiguous docking of the grippers with the cargo flange in places. Where there is no control over the docking process. The alignment of the joining is ensured by a rotary sleeve, which, by means of a drive slide with a rod, rotates the frame with grippers, spring fingers are installed in a zigzag groove, and a latch by means of a push rod allows the drive slide to move only if the centering ring is fully supported on the load flange. 1 s.p. f-ly; 7 ill.

Description

FIELD OF THE INVENTION The invention relates to load handling means and can be used for loading and unloading in places. Where there is no access for operators to the cargo, for example, in buried wells, mines.

The aim of the invention is to increase reliability.

In FIG. 1 shows a gripper in a position before a frame is rotated, section; in FIG. 2 - locking mechanism in position after the frame is turned, section; in Fig.3 - scan swivel sleeve; in FIG. 4 - node 1 in FIG. 3; in FIG. 5 - spring-loaded chipper, section AA in FIG. 4; in FIG. 6 - centering tooth, section; in FIG. 7 is a section BB in FIG. 6..

The load gripping device consists of a housing 1, a centering ring 2, connected by guides 3 with yokes 4, which serve to orient the device in the shaft of the shaft,

Ј the housing 1, on the rotary sleeve 5, a frame 6 is mounted, resting on a support-rotary circle 7. The frame 6 is a three-dimensional welded structure with rigidly fixed, evenly spaced grips in the lower part 8. The rotary-rotary circle 7 is installed between the frame 6 and the centering ring 2 and perceives weight loads on the frame 6.

The sleeve 5 and the frame 6 are connected by a key 9, which ensures their joint rotation.

The sleeve 5 consists of an outer cup 10 rigidly interconnected and two inner cups 11 having profiled ends on one side and forming a closed zigzag groove 12 on the inner surface of the sleeve 5. Consisting of periodically repeating rectilinear vertical a and inclined b sections , in each of which on the outer glass 10 there are spring-loaded fingers 13.

The length of the vertical section a is made more than the stroke of the slider 15, which allows

relieve the weight of the device from pin 14.; . . : -,.

The pin 14 of the drive slide 15, which is mounted with the possibility of vertical movement in the sleeve 5 and connected with the rigging 16, interacts with the zigzag groove 12. The tongue 15 is held by the key 17, which is installed in the top cover .18. The lid 18 is mounted on the housing 1. The downward stroke of the slider is limited by the lid 19, mounted on the frame 6.

The finger 13 has an upward section in and direct access D. located in such a way that the pin 14, when the slider 15 moves, interacts with the upward section in and presses a finger into the glass 10, after the passage of the pin 14, the finger 13 is returned by the spring 20 at

initial position and step d

prevents the pin 14 from getting into the groove portion that was passed in the previous stroke of the slider 15.

The combination of a rectilinear zigzag groove 12 with the fingers 13 located therein uniquely determines the movement of the pin 14 of the slider 15 and eliminates the violation of the cyclic operation of the device.

Through the flange 2.1, the slider 15 is fixed and in the extreme upper position by the stopper 22 held in this position by the spring 23. For the stopper 22, corresponding holes g are made in the sleeve 5. The stop 22 by means of a lever 24, d 25, the pusher 26 installed in the centering ring 2 comes out of the flats 21 of the slider 15 and the holes of the sleeve 5 and allows the slider 15 to move downward when the centering ring 2 is completely detached the flange 27 of the load 28 and the pusher 26 will choose its course.

Such a connection prevents the locking mechanism from triggering when the device is accidentally jammed in the shaft of the shaft, as well as when landing on a load with a skew.

An alignment tooth 29 is fixed in the centering ring 2. The alignment ring 2 and the alignment tooth 29 are intended to provide a predetermined orientation of the device with respect to the load 28.

The lifting device operates as follows.

With the rigging 16, the device is lowered onto the load 28, being guided in the shaft of the shaft with the help of yokes 4. The stopper 22 prevents the slide 15 from moving downward until the centering ring 2 of the device is fully supported on the flange 27 of the load 28. When landing on the load 28, the device is centered by the ring 2 in the transverse direction direction and installation

tooth 29 along the turning angle, while the grippers 8 enter into the rigging flange 27 of the load 28. The flange 27 is L-shaped sectors, the number of which is H equal to the number of grips 8 of the device, and the gap between the sectors exceeds the width of the grips 8.

When the centering ring 2 is fully supported by the flange 27, the pusher 26 selects its course and, by means of the bar 25 and the lever 24, disengages the stopper 22 from engaging with the slider 15 and the sleeve 5, allowing the slider 15 to move downward due to its own weight.

With its movement, the slider 15 through the pin 14 interacts with the inclined section of the zigzag groove 12 of the sleeve 5 and rotates the frame 6 at an angle M °, determined by the number H of grips 8

M ° 360 ° / 2N

In this case, the slewing ring 7 reduces the resistance to rotation of the frame 6.

After the frame 6 is rotated, the grippers 8 are under the L-shaped sectors of the rigging flange 27. Thus, docking with the load occurs. When lifting the device with a crane means, the slider 15 starts to move, the pin 14 of which moves along the vertical section a, while the inclined section b is blocked by the fingers 13, and the sleeve 5 with the frame 6 remains stationary.

After the stop of the slider 15 in the upper cover 18, the entire device begins to rise until a gap is selected between the lifting flange 27 of the load 28 and the grips 8 of the device. After that, the device with the load is lifted together, and the stopper 22, under the action of the spring 22, fixes the slider 15 in the upper position.

In order to undock the device from the load, it is necessary to install the load on the working platform. The device will work as if docking:

the frame 6 will rotate to the next M °, while the grips 8 will be between the L-shaped sectors of the rigging flange 27 and, when the device is lifted, will disengage from the load.
