Description

The invention relates to lifting and handling equipment, in particular to grippers for pallets with cargo.

Known grip for pallets with cargo, containing the enclosing frame, hung by means of slings ⁵ on the hook of the lifting mechanism, movable made in the form of strips, load-gripping bodies located in the lower part of the frame GN · ** ^J 1Λ

However, the known grab does not provide the rise of a pallet of variable height with small dimensions of the gap under the bottom.

The purpose of the invention - an increase in operating efficiency by ¹⁵ obes- baking tray lifting capabilities of variable height with the small size of the gap under the bottom.

The purpose is achieved by the fact that the grip is equipped with guide rods cantilever attached on one side of the frame in its lower part, a spring-loaded movable bar with 2 holes at the ends, in which the said guide rods are placed, with guide blocks for slings, one pair of which is located at the top of the frame, and the other is at the bottom, while the sling is attached to the movable bar, and the gripping organs are fixed on its lower part.

To increase the strength, the grip is equipped with a coupler connecting the ends ^{z of the} rods.

To increase reliability, the grip is equipped with handles fixed to its external parts, and a folding latch mounted on the screed with the possibility of interaction with the movable bar.

Figure 1 shows the frontal projection of the capture, a thin line shows the pallet; figure 2 - a view of figure 1; in Fig.3 - view B in Fig.1; figure 4 is a cross-section bb in figure 2; figure 5 is a cross section GG in figure 1; figure 6 is a view of D in figure 2; in Fig.7 1. From the bottom two frame with axes, section MF in Fig.2; on Fig view E in figure 2.

The grip consists of a frame on the side of the frame 1 welded 'gripping body 2. On top of 1 are welded two brackets 3 on which the rope slings are worn 4. The slings 4 together with the adjustable rope slings 5 located on the opposite side of the grip converge to the oval link 6, behind which grip is hung on a crane hook. The sling 5, touching the block mounted on the bracket 7, goes down to the bottom of the grip, where it is deflected by the block 8 and joins the strap 9, which (like the frame 1) in its lower part has two gripping bodies 10. In a closed grip, the pallet lies on the gripping organs 2 and 10 (figures 1 and 7). From above, from falling off of the closed grip from the pallet, in case of accidental loosening of the slings, the guards 11 protect them (Fig. 7). The gripping organs together with the guards form a] -shaped shape. The strap 9 can move along the cantilever rods 12, and it is constantly pressed against the frame by springs 13.

To ensure structural rigidity, the rods 12 are connected by a screed 14. In the open and closed positions, the grip is held by a folding latch 15, which is a bar with two grooves, with which the latch is put on the screed 14. The frame and other gripping elements are equipped with handles located from the outside of the capture, i.e. from the side opposite to the pallet to protect the worker’s hands from burns.

Capture works as follows.

Aside from the pallet, the worker opens the grip, for which, holding his left hand _t on the handle welded to the coupler 14, with the same hand raises the hinged latch 15 (Fig. 2).

After that, with the right hand for the handle mounted on the bar 9, takes the bar 9 to the screed 14, deforming the springs 13. The worker fixes the retracted bar ^ 9 by the catch 15. The grip is open. The worker opens the opened grip to the standing pallet (with or without a shell) and puts it on top of it. Then, holding the handle of the frame 1 with his left hand, the worker introduces the gripping organs 2 under the pallet, then

839980 4 holding the screed handle 14 with his right hand, opens the latch 15, the springs 13 feed the bar 9 to the pallet and the gripping organs 10 fall under the pallet. Capture is closed. Closed grip worker fixes the latch 15. On the weight of the rope slings 5, stretching, press the bar 9 to the pallet. The grip cannot accidentally be opened, as this is prevented by the latch 15.

The proposed grip provides the possibility of lifting a pallet of variable height with small dimensions of the gap under the bottom, which increases its efficiency.

Claims (3)

The invention relates to a lifting-transport equipment, in particular to grippers for pallets with cargo. A known grip for pallets with a load, containing a walling frame, hung by means of a sling on a hook of a load-lifting mechanism, movable load-gripping bodies made in the form of slats, is placed at the bottom of the frame l. However, the known grip does not provide for raising the pallet of variable height with the small dimensions of the gap under the bottom. The purpose of the invention is to increase the efficiency in the operation by both of the liver of the possibility of raising the pallet of variable height with small dimensions of the gap under the bottom. The goal is achieved by the gripper being provided with cantilever rods with a cantilever arm attached to one side of the frame in its lower part, a spring-loaded spring-loaded plank with openings at the ends in which the said guide rods are placed and the guides for the lines to the slings, one pair of which is located at the top of the frame, and the other - at the bottom, with the sling attached to the movable plate, and the gripping bodies attached to its lower part. To increase the strength, the grip is equipped with a stitch connecting the ends of the rods. For reliability, the grip is provided with handles fixed on its external parts, and a hinged lock installed on the tie bar with the possibility of interaction with the movable plate. Figure 1 shows a frontal projection of the grip; a thin line shows a pallet; figure 2 is a view of And figure 1; on fig.Z - view B in figure 1; figure 4 - section bb In figure 2; figure 5 - section GG in figure 1; PA 6 - type D in figure 2; Fig.7 section MF in Fig.2; in FIG. 8, view E in FIG. The grip consists of frame 1. From the bottom, two gripping bodies 2 are welded to the frame 1. Two brackets 3 with axles welded by cable joints 4 are welded to the frame 1. Slings 4 together with adjustable rope slings 5 located on the opposite side grip, convergence to the oval link 6, at which the grip is hung on the crane hook. Sling 5, touching the block, mounted on the bracket 7, goes down to the lower part of the grip, where it is deflected by block 8 and attached to the bar 9, which (like the frame 1) has two gripping members 10 in its lower part. the grip of the pallet lies on the gripping bodies 2 and 10 (fig. 7). From the top of the closed grip from falling down from the pallet, in case of an accidental weakening of the lines, the limiters 11 (Fig.7) are prevented. The gripping bodies together form a shape. Punk 9 can be moved along cantilever rods 12, and it is constantly pressed against the frame by springs 13. To ensure the rigidity of the structure, the rods 12 are connected by straps 14. In the open and closed position, the grip retains the flap 15, which is a bead with two grooves, with the help of which the lock is put on the grip 14. The frame and other gripping elements are provided with handles located on the outer side of the gripper, i.e. from the side opposite to the pallet to protect the worker's hands from burns. The gripper works in the following way, in the side of the pallet, the worker opens the gripper, for which, holding the handle with his left hand, is welded to the boom 14, with the same hand lifts the flap 15 (.Fig.2). After that, the right hand for the handle, reinforced on the bar 9, retracts the bar 9 to the stud 14, thus deforming the springs 13. The worker retracted the bar 9 by means of the latch 15 ... The grip is open. The worker opens the grab to the standing pallet (with or without a shell) and puts it on top of it. Then, holding the frame handle 1 with his left hand, the worker enters the gripping bodies 2 under the pallet, then. 8 4 holding the handle 14 with the right hand, opens the lock 15, the springs 13 feed the bar 9 to the pallet and the gripping bodies 10 fall under the pallet. Capture is closed. The worker grasps the locked grip with locking pin 15. On the weight of the rope slings 5, tension the clamp bar 9 to the pallet. It cannot accidentally open the grip, as the latch 15 prevents this. The proposed grip provides the possibility of raising the pallet of variable height with small gap sizes under the bottom, which increases its efficiency. Claim 1.
