Abstract

The invention relates to the mining industry, namely, to devices for lifting the rock mass from deep quarries in the development of open pit minerals. The purpose of the invention is to simplify the drive. A vehicle lifter contains inclined guides, a loading platform moving along them, equipped with an emergency stop system, upper and lower loading and unloading stations, a haul rope and a drive made in the form of a tractor, such as a quarry locomotive connected to a load platform on wheel balancers trolleys by means of a rope that interacts with the means of limiting tractive effort on a tonne load, and at the upper loading and unloading station in the area where the load platform stops, . The limiting traction safety device on the tire is more kinematically connected with its braking system. The stop is provided with a closed hydraulic system in the form of a pressure cylinder that is hydraulically connected to spring-loaded power cylinder rods connected to working clamps placed on the traverse of the berth station before stopping, and working clamps are designed to interact with the wheels of the balance trolleys mounted on the load platform 3. 2 hp f-ly, 4 ill.

Description

The invention relates to the mountainous npoffrinuieHHocTH, namely to devices for lifting the rock mass from a quarry when developing useful minerals. digging in the open way.

The chain is invented - simplified with water.

 FIG. 1 shows the general scheme of the lift, the section; in fig. 2 - clips with hydraulic drive; FIG. 3 shows an upper loading and unloading station with automation elements, a loading platform and a closed hydraulic fixation system.

A device for lifting vehicles with mountain mass contains inclined guides I, made in the outgrowth of one pair of rails, a berth station 2, into the walls of which are position sensors of the loading platform 3 installed on the horizontal section of the bridge, disconnecting unit 4, limiting stop 5, shock absorber 6, the rail track of the locomotive-gacha 8 and the limiting stop with a shock absorber 9. On the lower horizon of the quarry, a lower quay station 10 is mounted, equipped with shock absorbers-closers P. On inclined guide ps The loading platform 12 is located, having the ability to move along inclined guides on the balance trolleys 13. The cargo platform is equipped with bypass caps 14, which are stored by the load rope 15. The vehicle 16 for the rock mass during lifting is on the loading platform, which in the upper quay station during loading and unloading rests on clamps 17 connected by a main line 18 with a pressure head valve 19 and a sensor 20 of the boundary position of the platform 3 controlling the brake system Gacha The brake system is activated by the signal of the safety unit 2I of the limiting traction force. The operating latches consist of folding stops 22 constituting a single unit from rail 23, levers 24, cylindrical rotors 25, stops 26, housings 27, fixed crutches 28 on cross ties -29 on both sides of each inclined rail.

The device works as follows.

In the initial position, the loading platform 12 is located on the lower mooring station, and the locomotive 8 is located at the limiting stop 5. The vehicle 16 with a load enters the group

Zovy platform 12. Locomotive starting

The moving platform 12 moves to the upper quay station 2. When the cargo platform 12 approaches the upper quay station, alternate position sensors of the cargo platform 3 are triggered, instructing the locomotive 8 to slow down. . Then, at low speed, the loading platform comes into contact with the buffer of the pressure hydrocyliidra-stop 19, turns on locks 17. Then the limit position sensor 20 of platform 3 turns on the braking system of the locomotive 8. After stopping the locomotive, somewhat loosening the brakes, rolls back before the moment when the wheels of the balancing carts 13 will enter

with a buckle with clamps 17. Next, the vehicle with cargo moves out of the cargo platform, making way for empty.

After loading the cargo platform, the locomotive begins to move or quarry, the cabfciM releasing the latches, and acts on the hydraulic cylinder-stop 19, which withdraws the stops of the latches to the sides. The locomotive then changes direction and, moving to the quarry, lowers the load platform to the lower berth station 10, equipped with platform position sensors 20, similar to the upper berth station. After reducing the speed, the loading platform comes into contact with shock absorbers-closers 1I, which stop it in the initial position, F o rmula of the invention
