Description

Pincers for grabbing unit loads are known, which move parallelly when a load is seized. They are made in the form of a hinged four-door and equipped with a device to automate their work. However, such tongs do not provide for the adjustment of the solution of their clips and their grip in height.

In the proposed tongs, the asterisks of the locking mechanisms are mounted movably in the slots of the wings of the clamps, and their stops are fixed coaxially with the fingers of the wings on the links x. The locking mechanism is made with guide plates, and the stop is equipped with a retractable rod. This difference makes it possible to grab loads of various sizes, both in height and width, with rivets of the same type-size.

FIG. 1 schematically shows ticks; in fig. 2 is the same, in sections along aa and bb of fig. one.

The central welded frame / bears on the axis of the hinge two intersecting t g 2 to 3, as well as an emphasis 4, which serves as a point of support for the work and capture. Ти 2 and 5, and the identical construction, together with bars 5 and b, represent the hinge parallelogram. A fork 7 is fastened to the upper pivot point of the parallelogram with an eyebolt 8, to which a crane hook clings. The fingers 9 tons 2 and 5 slides in the grooves of the clips 10 and are supports when the clips work. The semicircular stops 11, which are on the same axis with the fingers Y, drive the sprockets 12. The sprockets 12 are seated on the bolts 13, which have the possibility of mixing in the forks of the clamps 10 and being fixed in the right place.

In addition to the asterisks, the bolts 13 hold the baskets 14 with the guards of 15 square sections and move along with them. The flap 15 serves to protect the sprocket 12 from accidentally turning while the fingers 9 tg 2 and 5 are located in the upper part of the grooves of the clamps 10. The flap has a longitudinal hole in the center in which the head of the guide pin 16 is placed. with hole 5-6
