The longitudinal movement of the bracket 2, connected to the cylinder body 3, the ends of the rod 4 of which are fixed on the base 1. On the bracket 2 are installed deflecting sprockets (blocks) 5 and 6 and the drive sprocket 7 on the same shaft with gear 8, which is in engagement with rail 9 installed on the ground. The chain 10 is fixed with the ends on the bracket 2 and spans 5, 6, 7, 12, 13 with the formation of two branches. The horizontal sections of the chain 10 are meshed with the teeth 15 of the upper section 16. 2 Il.

FIELD OF THE INVENTION The invention relates to lifting and transport equipment, in particular, to telescopic load grippers of hoists and stacker cranes.

The purpose of the invention is to reduce the overall dimensions of the load-carrying capacity by increasing the extension of the platforms.

The goal is achieved by the fact that an additional extension of the platforms is provided by moving the bracket along the base, on which the drive sprocket is mounted, which is connected to the gear that meshes with the fixed rack.

FIG. 1 shows the telescopic grip, the initial position; in fig. 2 - the same, in the extreme right position.

On the base 1 of the load gripper, the bracket 2 is mounted with the possibility of longitudinal movement. Connected, for example, to the body of the power cylinder 3, the ends of the rod 4 of which are fixed on the base 1. On the bracket 2 there are mounted deflecting sprockets 5 and b, the drive sprocket 7, on the same shaft the gear wheel 8 is attached, which is in engagement with the rail 9 mounted on the base 1. The chain 10 is fixed by the ends through the tension elements 11 on the bracket 2 and encompasses with the formation of two branches a drive sprocket 7, deflecting sprockets 5 and 6 sprockets 12 and 13 mounted on the lower ends of the drawer 14. The horizontal chain portions 10 are in engagement with teeth 15 of the upper section 16.

When pressure is applied to the right cavity of the cylinder 3, the latter moves along the rod 4 to the left, dragging itself at speed V with bracket 2 with deflecting sprockets 5 and b installed on it, driving sprocket 7 and gear 8, as well as through chain 10 lower section 14 and upper section 15. At the same time, gear 8, by engaging with fixed rail 9, rotates drive sprocket 7, which moves chain 10 from one branch to another, due to which lower section 14 moves relative to bracket 2 with speed Vi, and relative to base with

speed V + Vi. Since the upper section 16 is engaged by the teeth 15c by the chain 10, it then moves together with the chain 10 at a speed of 2Vi relative to the bracket 2 and at a speed of V + 2Vi relative to the base 1.

When pressure is applied to the left cavity of the cylinder, sections are likewise moved in the other direction.

Claims (1)

Invention Formula Telescopic load gripper containing base, lower and upper load-carrying sliding sections associated with it, the last of which is made with teeth on the bottom surface and section extension mechanism, including drive and deflecting sprockets placed in the base zone, deflecting sprockets at the ends of the lower section and enveloping all sprockets and attached ends to the chain elements located in the bottom zone, characterized in that in order to reduce overall dimensions, it is equipped with a bracket moving from the drive along the base, on which drive and deflecting sprockets and fastening elements of the ends of the chain, mounted in the base zone, are mounted shaft shaft drive sprocket gear and rail, mounted on the base above the latter and in contact with it.
