Abstract

This invention relates to a lifting and transport machinery. The purpose of the invention is to improve the operational capabilities by increasing the force of incorporation into the scoopable material. The grab contains a frame frame carrying buckets 1 and 2, which by means of axes 3 and 4 and levers 5 and 6 are connected with a transverse axis 7, which is passed through a bearing housing that interacts with the rod of the power cylinder 10 with a lid 11 fixed on the upper horizontal beam 12, resting on the side frames of the frame. On axis 7, rollers mounted in profiled rails 16 are mounted. The legs are pivotally connected to axis 17, and a lifting butt 18 is attached to beam 12. 3 sludge.

This invention relates to a lifting machinery industry and concerns grabs.

The purpose of the invention is to improve the operational capabilities by increasing the force of incorporation into the scoopable material.

Figure 1 schematically shows the proposed bucket capture, front view; figure 2 - the same, side view on fig.Z - the same, top view.

The grab contains a frame frame carrying buckets 1 and 2, which by means of axes 3 and 4 and levers 5 and 6 are connected with the transverse axis 7. The latter is passed through the bearing sleeve 8, which interacts with the rod 9 of the power cylinder 10 with the cover 11, fixed on the upper horizontal beam 12 resting on the side posts 13 and 14 of the frame frame. On axis 7, rollers 15 are mounted, which are inserted in profiled guides 16 connected to profiled guides located along racks 13 and 14. Racks 13 and 14 in the lower part are hingedly connected with the axis 17, passed through the inner edges of the buckets 1 and 2. A lifting butt 18 is attached to the beam 12. The nozzles 19 and 20 of the compressed air supply are connected to the cylinder 10.

The bucket gripper is equipped with a control panel for supplying compressed air in the cavity of the power cylinder 10.

Bucket grip works as follows.

The bucket grab is hung on a lifting device, such as an overhead crane, and transported to the place of work to seize the mass from the wells, rise to the surface and load into vehicles. The mass is a mixture of solid fractions (liquefied) collected in sewers (not

By supplying compressed air to the spout 20, the rod 9 rises, while the levers 5 turn the buckets 1 and 2 to the maximum solution.

The introduction of buckets into the mass is carried out by supplying compressed air to the nozzle 19, while the buckets are rotated in the opposite direction. The force of the cylinder 10 achieves a more complete filling of the buckets with solid fractions of the mass to be raised.

The proposed bucket grip provides a more complete filling of the buckets and high reliability in operation by the presence of a rigid frame and cat ™ forging movement of the transverse axis in the guides.
