Description

(54) GRIP BREEDING MACHINE

The invention relates to mine construction and is intended mainly for the construction of vertical shaft shafts of rectangular section. A GP-2 pneumatic forklift with manual driving is known, which is small in size and designed to work in shafts of a small section area. The loading of the rock in such trunks is currently carried out manually in an unsatisfactory state of safety. The drifter moves the grapple on weight at the level of 12OO-1500 mm, understood by the carrier. In order to scoop the rock from the opposite tub of the barrel walls, the sinker must first stand with its back to the tub, and then turn with the grapple 180 and unload the rock into the JJ tub. However, since the width of the machine, when turning, the sinker can involuntarily turn on one of the pneumatic valves The grab ram-or-pneumatic motioning cylinder and getting injured Another tunneling unit is known for harvesting rock when driving vertical shafts of mines, including a grab with a cable suspension on a lifting winch, ndsky frame and frame with deflecting unit. The disadvantage of this tunneling unit is that it cannot be used to drill narrow rectangular workings. The purpose of the invention is the vision effect. the ability to drill narrow rectangular workings. The goal is achieved by the fact that the frame is hingedly mounted under the rim of the ram with the possibility of rotation in the vertical plane. The drawing shows the device grab rock-loading machine. This machine contains a pneumatic grab 1, a lifting winch 2, which is mounted on a driving shelf 3. A suspension cable 4 of a pneumatic grapple 1 is passed through a deflecting unit 5 attached to

swivel frame 6, and mounted on this frame 6. On the hinge-swivel frame 6 secures the second rope 7 to the winch S. Pneumographer 1 is suspended using polyspastny block 9.

The rock loading machine is controlled from the installation site of the winches 2 and 8, equipped with an air control valve of the pneumatic cranes of the grapple 1. Winch 2 is installed so that the pneumatic gripper 1 tends to turn the frame 6 under its own weight and approach one of the walls of the trunk. The second winch 8 moves the frame 6 to the opposite wall of the barrel together with the pneumatic grab 1.

Winch 2 also descends the grapple 1.

In order to prevent rotation of the grab 1 and prevent the pneumatic expansion hoses from twisting and breaking, the grab 1 is suspended with the spacing of the branches of the suspension cable 4 using the polyspast block 9.

Instead of winches 2 and 8, one double drum scraper can be used per winch, additionally equipped with brakes for drums. This modification increases the efficiency of the installation, since the scraper winch has high reliability in operation in heavy underground conditions, high maneuverability and ease of operation.

To unload the pneumatic grappler 1, the latter is installed above the bucket 10.

turning the frame 6 with the winch 8 to the unloading position. After unloading the grapple 1, the frame 6 is retracted from the path of movement of the tub 10 by lowering the rope 7 with the winch 8, and the tub with the rock protrudes onto the surface.

The proposed rock loading machine improves the safety of the work of the sinkers who control the loading of the rock from the tunnel.
