Abstract

Use: for wrapping and fixing the cargo during loading and unloading operations. The invention: in the case of the lock, made of two cheeks, a roller is pivotally mounted, the bottom of the groove of which is made with a recess of a triangular section for accommodating a flexible element. The top of the elongated abutment of the spring-loaded rotary lock of the flexible element is made in the form of a prism with the convexly curved apex inward. 8 or

Description

The invention relates to lifting devices and can be used as a tightening device for a bound load.

A lock for a sling is known, comprising a body made of two cheeks extended on the roller placement side and connected in this area around the periphery by a half-sided guard, with one of the cheeks made with a slot for entering the chain and a second with a recess for accommodating the lug of the latch.

The closest in technical essence to the proposed lock is a tightening lock comprising a housing made of two cheeks, a hinged-mounted roller housed in it, a ditch bottom made with a recess, a flexible element around the roller with a gripping body at the end, and a spring-loaded latch flexible element with an extended stop, placed in the groove of the roller.

A disadvantage of the known locks is the inability to use the mx when using ropes.

The purpose of the invention is the expansion of operational capabilities.

This goal is achieved by the fact that the recess of the roller groove bottom is made of a triangular cross section, and the apex of the elongated abutment is in the form of a prism with an arcuately cut top, convexity inwardly of the abutment, the surface of which is made with a notch.

The case of the lock consists of a half-shell 1 connected to the front 2 and rear 3 cheeks.

Between the cheeks 2 and 3 on the axis A is placed a roller 5, made with groove b, and on axis 7 there is a stopper 8 fitted with an elongated stop 9 in the form of a prism with a convexity arcuately cut off by the apex inside the stop 9, the surface of which is made with notch 10 for the spring 11. and in the middle - with the eye 12 for remotely raspropovka package (not shown). On the axis 7, a transition ring 13 is installed, connected to the rope 14, the end of which is connected to the hook 15.

In order to improve the fixation of the rope 14, the recess 16 of the bottom of the groove 6 of the roller 5 is made of a triangular section with a notch on the sides.

For the convenience of inserting the cable 14 into the recess 16, the front cheek 2 is made with a notch 17, and for the convenience of gripping the stopper 8 behind the eyelet 12 in the back cheek 3 and the lower part of the front cheek 2, a notch 18 is made.

When using round link or lamellar chains, the stop 9 freely sinks into the recess 16, therefore the retention (locking) of the chains is accomplished by contacting the edges 19 of the side with the shoulders 20 of the stopper 8, since the edges 19 prevent the contact of the stopper 20 from shifting zhke package.

The strap lock operates as follows.

A sling of rope 14, round-link or lamellar chains is mounted on the transition ring 13, the package is grabbed and, moving the stopper 8 away from the roller 5 into the notch 17 and the gap between the roller 5 and the stop 9, insert the rope 14, drowning it into the groove 16 of the roller 5. The loosened stopper 8 with its elongated abutment 9 clamps the rope 14 between the walls of the recess 16 provided with a notch to increase

friction between the rope 14, the walls of the recess 16 and the bulge inside the stop 9, securing it from the return movement, i.e. from rasstropovki Hook 15 grab the rope or any chain link and the resulting loop, grabbing a lifting mechanism hook (not shown), lift and move the package to the appropriate place or rolling stock

The packet splitting is done in the following order.

After the package has been delivered to its intended purpose and laid in place at the disassembly point, the lug 12 clings on the eye (chain, rope, wire, rope) of the appropriate length and, if necessary, moves the stopper 8 to the side. The stop 8 pushed aside by the stop 9 does not hold the rope 14 (or any chain) that freely, under the pressure of the load, releases it. After this, having removed the stopper 8, the rope 14 is taken out of the recess 16 of the groove 6 and, hooking the lifting mechanism with the hook 13, pulls out the end of the sling (rope or chain) from under the load.
