Abstract

1. CAPTURE CROWLER, containing traverse support elements, pivotally attached to it at least one pair of two shoulders gripping arms, upper arms of which are hingedly connected by means of a h with an hitch element to a lifting machine, clamping pads and locking mechanism of gripping levers in an open a position characterized in that, in order to expand the range of sizes of the loads to be seized, it is provided with gripping levers fixed on the bottom heals rotatably in a plane, perpendicularly pivoting plane of the gripping arms, and spring-loaded relative to the last single-armed levers, the lower ends of which are fixed pressing pad. 2. The gripper is tilter according to claim 1, characterized in that it is provided with stop levers for single-arm levers fixed on the lower arms of the gripping levers.

Description

.

The invention relates to lifting transport devices. A tilting device is known, containing a traverse with supporting elements, at least one pair of two shoulders gripping levers hingedly attached to it, the upper arms of which are hingedly connected to the load-lifting machine clamping pads with the hinge element and the gripping mechanism of the gripping levers in open C 1 position. The disadvantages of this device are low labor productivity, a small range of gripping loads. The purpose of the invention is to expand the range of sizes of cargo to be captured. This goal is achieved by the fact that the gripper-turner containing the traverse with supporting elements is hinged at least one pair of two shoulders gripping levers, whose upper shoulders are hingedly connected by means of a linkage element to the lifting machine, clamping pads and locking mechanism of gripping levers in the open position, it is provided with gripping levers fixed on the lower arms with the possibility of rotation in the plane of the perpendicular PLANE of rotation of the gripping levers, and spring-loaded with respect to the last single-shouldered Mii fins, to the lower ends of which are attached the lanyard pads. Besides; The gripper is equipped with limiters for the rotation of single-arm levers attached to the lower arms of the gripping levers. Fig. 1 shows the capture with a load-carrying body, front view, in Fig. 2 - the same, side view. The gripper-tilter contains a straight angle beam 1 with supporting elements 2 "By traversing an articulated arm} at least one pair of two shoulders gripping arms 3 The upper arms of the levers 3 are hingedly connected by means of terminal 4 with element 5 of the linkage to the lifting machine, and The pads 7 are hingedly attached to the lower shoulders of the two shoulders of the gripping arms 7. The tilter is equipped with a mechanism 8 for locking the gripping levers in the open position. To the lower shoulders of the gripping levers by means of a spring 10, limiters 9 of rotation of single-arm levers 6 ,, are attached. The tilter tilter works as follows. Before the load is seized, the locking mechanism 8 locks the grips of the levers 3 together with the single-arm levers 6 with the pressure pads 7 in the open position. Using a crane, the grabber is lowered in order to grip and turn the bales from horizontal to vertical until the supporting element 2 touches the load. 7 are in a position that is offset to the end of the bale, for example, an amount from the center of its weight. Under the weight of hitch element 5, the locking mechanism unlocks the gripping levers 3 and, when lifting the gripper with the crane, the latter through the subroutine, the single-arm levers 6 are clamped with 7 clamping pads 7, for example, two bales of cheshlulosis The force of the clamping load is due to its weight. Turning the load when it is lifted spontaneously about the LINE the initial lifting of the load rod 10 stretches 5 spring loaded single levers 6 with the clamping block GF 7 rotates under the action of the weight of the load before turning the pressure pad in position 1, the gap between the ends of the bales increases and two The bales from the horizontal position A smoothly turn into a vertical position B. During the subsequent lowering of the -1 and gripping-cantoaTTsl mechanism-g 8 fixation fixes the two shoulders of the gripping arms 3 in the open position and the sub-spring The levers of the arm 6 with the clamping pads 7 are rotated to limit. pc 9 and hold the spring blue 10. The curtain holder retracts the load.

The pre-grip pick-up device for two bales can be used as with a manual locking mechanism.

and with an automatic one, which expands the range of sizes of cargo to be seized.
