Description

FIELD OF THE INVENTION The invention relates to lifting and handling equipment, in particular, to load handling devices. A lifting device is known, comprising a bracket connected to a hoisting mechanism hoisting mechanism, axles fixed on it, each of which is equipped with a gripping lever, one arm of which is installed so that it can interact with the load being taken, and the counter load that is alternately mounted. interaction with the second shoulder of the gripping lever and the mechanism for fixing the levers in the open position, which includes a spring-loaded lever 1. The load gripping device is both It makes an automatic gripping and unstripping of cargo, however, the presence of a flexible connection between the load handling device and the hoisting mechanism of the hoisting mechanism makes it difficult to point the load gripping to the load attachment device. The purpose of the invention is to improve ease of operation. The goal is achieved by the fact that in the load gripping device containing a bracket connected to the hoist, mounted axles on it, each of which is equipped with a gripping lever, one arm of which is mounted with the ability to interact with the load being held, and the second with a bracket , and a counterweight, installed with the possibility of alternately interacting with the second shoulder of the gripping lever and the mechanism of fixing the levers in the open position, including a spring-loaded lever, each of the gripping levers are made with a protrusion for engaging with a spring-loaded lever, and the bracket is hingedly attached to the axis of the chain hoist. FIG. 1 shows the load gripping device at the moment of its installation on the load, general view; in fig. 2 shows section A-A in FIG. 1 Lifting device contains a bracket 1, hinged on the axis of the polyspast 2, equipped with gripping levers 3 hinged to it 3. On the axis of the hinge of each gripping lever 3 rotatable mounted counterbalance 4, equipped with teeth, made on the supporting platform 5. On the supporting one the surfaces of each gripping lever 3 are provided with a protrusion 6 for interacting with the mechanism for fixing the gripping levers 3 in the open position when alternating the operations of gripping and releasing the load 7 (for example, the mounting loop). The locking mechanism is made in the form of a spring 9 arm 9, hingedly attached to the bracket 1 with the ability to interact with the protrusion 6 of the gripping arm 3. On the side of the lever 9 on the side of the counterpart 4 there is a tooth for engagement with the teeth of the counterpart 4 located on the supporting platform 5 . On the upper part of the lever 9, a handle 10 is made to retract the lever 9 upward when the counterbalance 4 is cocked. To stop the gripping levers 3 at the moment of lifting the load 7, a support scarf 11 is made on the bracket 1. The device operates as follows. Without load 7, the gripping levers 3 are in a horizontal position due to their performance with an offset center of gravity. When aiming the device. on the load, the gripping levers 3 are raised, the load 7 passes between them and when coming out of contact with the gripping levers 3, the latter fall and close the load 7. After tensioning the rope of the load-lifting mechanism, the levers 9 are retracted by the projections of the 6 gripping levers 3, overcoming the force of the holding springs 8, and gripping levers 3 abut against stop gussets 1. The tooth of the chug 9 comes out of the engagement with the teeth of the supporting platforms 5 of the counterweights 4 and the supporting platforms 5 fall onto the lugs 6 of the gripping levers 3, creating a turning moment. After installation of the load 7 and the required place, the load from the device is removed, the gripping levers 3 are rotated around the hinges. as a result of the action of the counter-loads 4, the way is cleared for the release of the load 7 from the engagement. The fixed brackets on the axis of the tackle block allow more efficient use of the load gripping operation, prevent the gripping of the load gripping due to the lack of flexible connection, which facilitates loading the gripping device onto the slinging device of the load, and saves time on the load gripping.
