Description

The invention relates to load-carrying means, in particular for loading (unloading) piece goods with rigging brackets, in a place where people (operators) cannot access the cargo, such as loading (unloading) cargo into deeper wells, mines and their automatic release ipi capture.

A known crane grip comprising a base connected to the base of a slider, in which a vertical rod is mounted for movement, to which a device for suspending the device on a crane is attached, pivotally attached to the base are gripping levers connected to the slider by means of t and double shoulders, and locking mechanism of the gripping levers.

The disadvantage of the crane grip is the possibility of counting the loading of the rigging nodes in the event of failure

one of the gripping organs, as each of them is fixed separately.

Closest to the present invention is a gripping device comprising a frame, gripping bodies, a stem, and a manual control mechanism.

A disadvantage of the known device is that before starting a cycle of operation, it is necessary to adjust the gripping device each time to the position to take the load or to give the load using a manual control mechanism, which increases the cycle time of loading or unloading the load, as well as the possibility of erroneous actions of the operator when setting up the gripper devices to the position of the load to take or the load to give.

The purpose of the invention is to increase the reliability and decrease the load time (discharge) cycle of the cargo by eliminating the manual control mechanism and creating an automatic adjustment of the gripping device XI Sl

5 Sleeve 20 (FIG. 1) is pivotally connected to the claw 5 by means of a bracket 26, ti 27, drove 28 and ti 29. On the sleeve 20 there are two spring-loaded clamps 30 (figs 3, 4 and 6). In the sleeve 24 (Fig. 2) and

0 Cup 17 (Fig. 1) is mounted shaft 31 (Fig. 2). The shaft 31 has the ability to dock with the hooks 32 (fig, 1) of a crane (not shown). The shaft 31 is provided with a groove 33, a ledge 34, an adjustable nut 35 (Fig. 2). On shaft 31

5, a closed zigzag groove 36 (FIGS. 2 and 5), which consists within 60 ° of the vertical sections D, E, the inclined sections B, D, K, I, D, to ensure operability in the grooves of section C, additional

0 grooves L.

A rotary cup 37 (Fig. 2) is mounted on the bearing 23, which is centered along the diameter of the shaft 31. The rotary cup 37 is equipped with a pin 38, three lugs 39 (Figs 2, 3 and 4) and six figured grooves 40 (Fig, 6) . Each groove 40 consists of a vertical section K, a horizontal section P and an inclined section M, Pin 38 (FIG. 2) is located with its end in zigzag shaped groove 36. Groove 33 (FIG. 1) interacts with pin 41, which is mounted on glass 17 excluding rotation of the shaft 31 (Fig. 2).

On the glass 17 in the capture plane 5

5 installation blocking mechanism 42, consisting of a spring-loaded latch 43, body 44, ti 45, rocker arm 46, ti 47 and pusher 48 (Fig. 1),

Bracket 4 has lead-in cones 49

0 (Fig. 1 and 7) and 50, which provide the centering of the gripping device on the rigging brackets 51 of the load 52.

The groove 22 (FIG. 2) of the sleeve 20 is engaged with the pin 53 mounted

5 on the glass 18, excluding the rotation of the sleeve 20. The gripping device operates as follows.

The pickup device is docked with the hook 32 of the crane and rises upwards, first the center rod 19 rises upward,

until the nut 35 (Fig. 2) rests on the beam 14 (Fig. 8), while the pin 38 (Fig. 2) is in one of the points M (Fig 5) of the groove 36 (Fig 2), the stops 25 and 39 (FIG. 3) are in mutual engagement, and when the rod 19 is raised upward, the point M begins to raise the cup 37, and in turn, it raises the sleeve 20 (FIG. 2). Since the sleeve 20 is kinematically connected with the grip 5, it moves from the center and extends beyond the conical surface 49 (Fig. 1) of the bracket 4. This is provided by the size (Fig. 5) of the shaft stroke 31 (Fig. 2) overhead The end face 34 will be above the latch 43 (Fig. 8). In this position, the gripping device is ready to dock with the load 52, which is located in the well. Having started the gripping device into the well with the help of a crane, it starts to lower and its bows (Fig. 1) are oriented. When the load 52 is reached, the gripping device with its taper elements 49 (FIG. 1) 50 (FIG. 2) is finally centered and the device is mounted on the load 52 (FIG. 1), while the pushers 48 from interacting with the surface of the brackets 51 unlatching the latch 43 with the abutment 34 (FIG. 8) and the shaft 31 starts to fall; in this case, the side surface of the inclined section D of the groove 36 (FIG. 5) is pushed onto the pin 38, rotates the cup 37 through a predetermined angle.

When turning the glass, with its shaped groove 40 (FIG. B) (surface M), the retainer 30 is inserted, which with its cone begins to act on the end K of the glass 32, excluding the possibility of rotating the glass in the opposite direction, which guarantees the pin 38 to enter the section G of the groove 36 (Fig. 5). After the movement of the shaft 31 stops, it is installed on the cup 18 (Fig. 2), the crane ropes are glorified, which indicates that the gripping device is ready to unload the cargo 52. Since the shaft 31 is kinematically connected with the gripper 5, when lowering shaft 31 grips 5 sets in the area of rigging brackets 51.gruza 52,

The stops 25 and 39 (Fig. 4) do not interact with each other.

When lifting the gripping device upward, the shaft 31 rises up first up to the stop of its nut 35 into the beam 14 (Fig. 8). With this lifting, the shaft 31 by the section D cannot act on the pin 38 (Fig. 2) and the glass 37 does not kinematically interact with the grippers 5 (Fig. 8). When the shaft 31 is lifted up (the rise of the shaft 31 is approximately equal to 1 (Fig. 2, 5), the gripping device is being prepared for undocking from the load, which is / g that the pin 38 (Fig. 2) is in the area of the groove L, and the second retainer 30 again acts on the end K of the glass 37 (FIG. 6), directing the pin into the area B of the groove 36, and therefore, when the load 52 is placed on the ground (or into the well), the gripping device is undocked from the rigging brackets as described earlier

Thus, the cycle of operation of the gripping device is repeated and it constantly works in the alternating mode. Load, take, Load.
