Description

The invention relates to hoisting machinery, in particular to cargo captures.

Known cargo capture containing a sling and a lock, comprising a housing with slots and mounted on one end of the sling [1].

The well-known cargo capture is characterized by complexity, low safety equipment, unreliable operation, since after opening the lock the cargo can injure the worker, the lack of insurance from spontaneous opening.

The purpose of the invention is to increase reliability.

To achieve this goal, in a load gripper containing a sling and a lock, including a body with slots, mounted on one end of the sling, the latter is a plate articulated between them, in which said slots are made, to which the locking loops are staggered, and the load gripper is equipped with a rod connected to the other end of the sling for placement in locking loops and a ring for remote opening the lock and a safety splint secured to one and the other ends of the rod, respectively th. ¹

In another embodiment, a load gripping device comprising a sling and a lock (including a body with slots fixed at one end of the line, two figured stops for the sling are fixed inside the body on its back wall, and the slot is made in the front wall of the body, while the load gripping is provided with a fixed at the other end of the line with a locking wedge with a ring.

In FIG. Figure 1 shows the '5 cargo load in closed position, general view; in FIG. 2 - the same, axonometry; in FIG. 3 - load gripping in the open position, general view, perspective view, in FIG. 4 is a section AA in FIG. 1; in FIG. 5 - front load capture in the second embodiment, general view; in FIG. 6, section BB in FIG. 5; in FIG. 7 - the same, in the version with a rope; in Fig. 8 a section BB in fig. 6.

The load capture (the first option) contains a sling 1 with a lock at one end, the body of which includes pivotally connected between each other loops 2 of the plate 3 and 4, having apertures 5 and 6 for placement in them of the chain 7 of the sling 1, at one end of the plate 3, a loop 8 is made in which the adapter ring 9 of the sling 1 is fixed. The other end of the sling is connected by the opening ring 10 with a locking rod 11 included in the locking loops 12 and 13 and having a hole 14 for the safety pin 15 at the end of the hole.

Cargo capture works as follows.

I

The formed package of cargo is tied with a sling 1, after the corresponding sealing of the load, chain 7 is laid on the plate 3 so that half of the chain link 7 'enters the slot 5, and, turning the plate 4 on the hinge loop 2, cover chain 7, while the second half of the link enters the slot 6, and the locking loops 12 and 13 are combined, after which the lock case is locked by the rod 11. To prevent spontaneous extension of the rod 11 and the lock to be opened, a cotter pin 15 or piece of wire is inserted into the hole 14 located at the end of the rod 11 akrutki.

The lock is opened in the reverse order. After the package is installed in an appropriate place, the safety pin 15 or wire twist is removed from the rod 11 and, having hooked the lifting mechanism 'hook onto the opening ring 10, the hook is lifted up. The rod 11 comes out of the locking loops 12 and 13 and the lock opens.

In the absence of a lifting mechanism, in order to avoid injury to the worker with a packaged load, the lock is opened remotely. To do this, after installing the package in the appropriate place and removing the safety pin 15 or wire twist, attaching the rod (rope, wire, cable, etc., not shown) to the opening ring 10, pull the rod 11 from the appropriate distance; from the locking loops 12 and 13 and the lock opens, while in both _v cases, the line 1 is pulled out from under the package.

The cargo capture (the second option) contains a sling 1 with a lock at one end, which includes a housing in which the rear wall 16 is provided with curly stops 17 for the chain 7 of the sling 1 and a hole 18 is made in it with an adapter ring 9, and in the front wall 19 it is made a slot 5 for introducing the chain 7, while the front wall 19 fixes the locking wedge 20, fixed by means of a ring-check 21 on the other end of the line 1. Spontaneous opening of the lock is excluded by wire twisting 22.

Cargo capture works as follows.

The formed package of cargo is tied with a sling 1 and, after appropriate sealing of the cargo, the chain 7 is inserted into the slot 5 so that one link of the chain 7 passes between the figured stops 17, and the lower link is located across the lower edges of the figured stops 17, after which between the figured stops 17 and the front wall 19, the tightening wedge 20 is inserted into the tight fit so that the ring-check 21 is higher than the transitional ring 9. To avoid possible self-opening of the lock by the safety wire twist 22, the transitional ring 9 is connected with m proximal thereto link chain sling 1.

The lock is opened in the reverse order. After installing the package in an appropriate place, remove the safety wire twist 22 and, hooking the lifting mechanism onto the ring-pin 21, lift it up. The locking wedge 20 disengages from the curly stops 17 and the wall 9, releases the slot 5 and pulls the chain 7 through it.

In this case, the lock opens automatically.

(

In the absence of a lifting mechanism, in order to avoid injury to the worker with a packaged load, the lock is opened remotely. To do this, after installing the package in the appropriate place and removing the safety wire twist 22, attaching the rod (not shown) to the ring-ring 21, the locking wedge 20 is pulled from the appropriate distance and the lock opens, while in both cases the sling 1 is pulled out under the load.

The proposed load capture is reliable in operation and safe in operation.
