V which ba with a screwed finger.

| Used in any industry when loading and unloading slaves are well-known for lifting goods, in which the lock is used as a lock. The drawback of the bracket is that you must unscrew the finger before installing it on the sling branch, and then, after passing the + branch of the sling, the finger is screwed in and Finally, after transferring the load, it is again necessary to unscrew the finger, all this increases the complexity of the process. In addition, in the process of removing the bracket, the rigger has to be located on the path of the rolling pipes, which often leads to injuries.

A pin-sling load gripping device is known in which a cable sling is used to capture the load, and the pin device serves as an auxiliary device for convenient distribution at a distance from the load. The disadvantage of this device is the lack of fixing the pin in the frame, which does not exclude spontaneous loss of it at the time of lifting the load.

Known pin lock (prototype) containing a bracket, with through coaxial holes in the branches, a hollow cylindrical frame located in the latter, a spring-loaded rod mounted on the end of the frame, a cap connected to the rod and a rod movement control element.

The disadvantage of this device is the lack of reliable fixation of the frame in the bracket.

The purpose of the invention is to increase the reliability of fixing the pin in the lock bracket.

This goal is achieved by the fact that the pin is made with the possibility of placement in the holes of the bracket with a free end protruding beyond the bracket, in which a longitudinal cavity and a through transverse hole are made, while the lock is equipped with a pin lock in the working position, made in the form of a pair of rings freely placed on rods fixed longitudinally in said hole of the pin, the rod is made with a tip for placement in the pin between the rings and is rigidly connected to the cap, which in turn is connected to a flexible rod.

In Fig.1 shows a General view of a pin lock: in Fig.2 is a view A in Fig.1; Fig. 3 view B in Fig.!

The lock consists of a bracket 1, pin 2, rod 3, sleeve 4, cap 5, spring 6, two rings 7 installed on the rods 8, flexible rod 9. The rod 3 has two working and non-working positions. Figure 1 shows the operating position. In this position, the tip of the rod is located in the cavity of the pin between the rings and serves as a support. In this case, the rings protrude beyond the cylindrical surface of the pin, thereby preventing the pin from moving through the through holes of the staple branches, i.e., the pin is fixed in the bracket.

When the rod is inoperative, the tip is extended from the cavity between the rings. To do this, it is necessary to tighten the flexible rod 9, while the cap 5 and the rod 3 rigidly connected to it move, passing freely through the sleeve 4. In order to fix the rod in the inoperative position, the following is provided. The sleeve 4 with its upper end enters the slot of the cap 5 (Fig.Z). If, after the cap is pulled by a flexible rod, turn it around its axis by a certain angle and release, then the end of the cap 5, under the action of the spring 6, will sit on the end of the sleeve 4 and the rod connected to the cap will be locked in the inoperative position.

The device is used as follows. The sling on which the lock is mounted covers the carried load. One loop of the sling is suspended on the crane hook, the other loop is put into the bracket! and through it, as well as through holes, a pin 2. is inserted in which the stem 3 is in an inoperative position. After the pin 2 is installed in the bracket, it is necessary to fix it, for which the cap 5 is rotated until the protrusion of the sleeve 4 does not coincide with the slot in the cap 5. Under the action of the spring 6, the rod 3 occupies the working position and its tip pushes the rings 7 so so that they protrude beyond the cylindrical surface of the pin 2. The pin 2 is fixed relative to the bracket 1 and at any positions of the lock it is prevented from falling out of the bracket. After the cargo is transferred, it is necessary to unfasten the lock.

For this, standing at a distance from the load, they are pulled by a flexible rod 9. The cap 5, together with the stem 3, moves, and the cavity under the rings 7 is released. Further tension of the flexible rod 9 leads to the fact that the rings are recessed in the holes, abutting against the branches of the bracket 1. Pin 2 is removed from the bracket 1 and the loop loop is released. Subsequently, the cap 5 is rotated by a certain angle and the stem 3 is fixed in the inoperative position. Thus, the load 3 is safely distributed, and the lock is prepared for further use.
