Abstract

The hydraulic connection of the integrated brake circuit is intended for suspension locomotives. Two one-way valves are connected in series with the hydrogenerator, and between them are connected in parallel on the left side a one-way valve, disconnector and manual hydrogenerator, and on the right an indirectly controlled pressure valve, while the first branch terminated by a hydraulic actuator is connected after the one-way valves, the second branch with at least one brake cylinder and the third branch with a hydraulic accumulator.

Description

261848

The invention encompasses the hydraulic engagement of the integrated wedge circumference and the start of the lateral locomotive intended for the transverse condition.

Previously known auxiliary hydraulic circuits of mining locomotives are designed to have a separate brake circuit, a separate starting circuit of the combustion engine, and.

The disadvantage of such a solution is the complexity, the increased mass, which is particularly disadvantageous for mining equipment. Cost and maintenance costs are also increased. In hydraulic start-up, the filling of the hydro-accumulator of the starter is solved from several separate sources.

Its disadvantage is that the refilled pressure is provided through these sources. There is often a failure of the starting circuit or a higher value of the pressure drop.

The disadvantages of the prior art are eliminated by the hydraulic connection of the integrated brake circuit and the starting of the suspension locomotive of the invention, the principle of which is that two unidirectional valves are connected to the radial generator and are not connected in parallel between them from the left side of the unidirectional valve, the disconnector and the manual hydraulic generator, and from the right side, the indirectly controlled pressure valve, the downstream valves being parallel connected trivetvy, the first branch being terminated by a hydraulic actuator, the second branch being at least one hydraulic brake the cylinder of the atrium branch of the hydraulic accumulator.

The essence is also that in the first branch, the pinion distributor and the hydraulic starter are connected in series and the brake distributor and brake actuator controlled by the speed limiter are connected in series to the second branch, and at least one hydraulic brake cylinder and the winding branch are sequentially in the series of pressure sensing of the indirectly controlled pressure valve, a controlled one-way valve and a pressure gauge connected in parallel. The advantage of the hydraulic connection of the integrated brake circuit and the starting of the suspension locomotive of the invention is that it is simpler and safer in providing optimum functionality. It is also advantageous that it allows for a design with smaller dimensions and lower weight, which is particularly desirable for mining mine locomotives. The supply of pressurized fluid from external sources is controlled by a pressure valve. Remote control is enabled.

In the accompanying drawing, Fig. 1 illustrates, in an exemplary embodiment, the hydraulic connection of the integrated brake circuit and the start of the suspension locomotive.

Hydro, generator 3 is connected to, tank 1 through the cleaner. Two unidirectional valves 4 are connected to it. An additional one-way valve 4, a disconnector 5 and a manual hydrogenator 6 are connected to the right side, and an indirectly controlled pressure valve 7 is connected indirectly to the melting side. branch 11, where a direct-controlled pressure-controlled switchgear 8 is connected with the possibility of manual control. In the second branch 12, air-operated and hand-operated distributors 21 are connected, a brake actuator operated by speed limiter 22 (via air) as well as an emergency and braking cylinders 23. In a third branch 13 ' accumulator 33.

By using a pressure start circuit for the first start, the generating pump 6 through the disconnector 3 supplies the third valve 13 through the controlled one-way valve 31 to the hydraulic accumulator, and 33 to the value directly directed by the controlled pressure valve 7 on the pressure gauge 32. - however, to be supplied with another external source via the disconnector 3. The start-up is activated either by the remote control from the panel by air-forming a controlled one-way valve 31 and by moving the directly-controlled ro-holder 8 from position A to position B or by pushing the surfaces manually. As a result, the insertion of the pinion of the hydraulic actuator 9 takes place and the pressurized fluid from the hydraulic accumulator 33 brings it into operation.

After the combustion engine 14 has been started, the hydro-accumulator 33 is supplemented with a pressure fluid from the hydrogen generator 3, which exits through the cleaner 2 from the tank 1. After the accumulator 33 and the brake circuit are refilled, the pressure-free liquid 3 flows through the indirectly controlled pressure valve 7 into the tank 1.

The brake circuit is connected in the basic position (braking state) such that the pressure fluid is from the hydraulic brake cylinders 23 by a spring force pushed into the tank 1cez the brake distributor 22 position A, controlled by the speed limiter and the brake distributor 21 position A. When the brake is released, the brake distributor 21 and the brake distributor 22 are shifted to position B. The gas generator 3 driven by the combustion engine 14 sucks through the cleaner 2 from the tank 1 and supplies the pressurized fluid through a pair of impellers. the valves 4 to the second branch 12 and the brake distributor 21 to the hydraulic brake cylinders 23;

The pressure fluid in the brake cylinders 23 will spring force and be released. The set pressure value in the circuit is ensured indirectly by the pressure-controlled valve 7. At the stopping or failure of the pressure-limiting motor 14, either the hand-held hydraulic pump 6 or other external pressure source connected to the disconnector 5 is provided.
