Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the present embodiment provides a monorail crane vehicle that includes an engine 1, and a hydraulic starting device 2 for starting the engine 1.

The hydraulic starting device 2 comprises a hydraulic oil tank 21, an energy storage tank 22, a pressure switch 23 and a hydraulic motor 24.

The hydraulic oil tank 21, the accumulator tank 22, the pressure switch 23 and the hydraulic motor 24 form a hydraulic circulation main oil path in this order.

The hydraulic starting device 2 further comprises a wind power pressurizing machine 25, wherein the wind power pressurizing machine 25 comprises a wind power transmission assembly 251 and a hydraulic pump assembly 252, and the wind power transmission assembly 251 drives the hydraulic pump assembly 252 to rotate.

The inlet end of the hydraulic pump module 252 communicates with the inlet end of the hydraulic oil tank 21, and the outlet of the hydraulic pump module 252 communicates with the inlet end of the accumulator tank 22.

The wind actuator assembly 251 includes an air inlet conduit 253 for communicating with a source of high pressure air.

It should be noted that: in general, the hydraulic starting apparatus 2 mainly uses a hydraulic circulation main oil passage.

The working process of the hydraulic circulation main oil way is as follows: when the engine 1 needs to be started, the pressure switch 23 is operated, the pressure-bearing hydraulic oil in the energy storage tank 22 enters the hydraulic motor 24 and drives the hydraulic motor 24 to rotate, the hydraulic oil in the hydraulic motor 24 finally returns to the hydraulic oil tank 21, and the hydraulic motor 24 rotates and drives the engine 1 to be started.

It needs to be further explained that: in order to ensure that pressurized hydraulic oil is fed into the accumulator tank 22, a hydraulic pump is arranged between the accumulator tank 22 and the hydraulic oil tank 21. After the engine 1 is started, the engine 1 drives the hydraulic pump to rotate, the hydraulic pump fills hydraulic oil into the energy storage tank 22, and the energy storage tank 22 filled with the hydraulic oil is used for starting the engine next time.

The hydraulic oil in the energy storage tank 22 can only start the engine 1 once, and if the engine 1 cannot be started normally, the engine 1 cannot drive the hydraulic pump to fill the energy storage tank 22 with the hydraulic oil. At this time, the wind power pressurizing machine 25 is required to store energy in the energy storage tank 22. The high-pressure air source in the mine is connected through an air inlet pipe 253, the high-pressure air source drives the wind power transmission component 251 to rotate, and the wind power transmission component 251 drives the hydraulic pump component 252 to fill hydraulic oil into the energy storage tank. When the pressure of the hydraulic oil in the energy storage tank 22 reaches a certain value. The delivery of pressurized air into the wind drive assembly 251 is stopped. The pressure switch 23 is then operated to start the engine 1 by hydraulic oil in the accumulator tank 22.

In the embodiment, the wind power pressurizing machine 25 is arranged, so that the air source of a mine can be used for pressurizing the energy storage tank 22, the use of manpower is saved, and the use convenience of the monorail crane is improved.

The wind drive assembly 251 further includes an impeller cavity and an impeller. The impeller sets up in the impeller intracavity, and the impeller shaft of impeller and the input shaft of hydraulic pump subassembly, the air inlet and the intake pipe intercommunication of impeller chamber. The impeller is driven to rotate by the gas entering the gas inlet pipe.

The air inlet pipe 253 includes an inner rubber layer, a steel mesh layer, and an outer rubber layer. The steel mesh layer is a mesh structure woven by steel wire ropes, and the steel mesh layer is arranged between the inner rubber layer and the outer rubber layer. The air inlet pipe 253 with the three-layer structure has certain flexibility and strong structural strength.

Referring to fig. 3 and 4, the end of the air inlet pipe 253 is provided with a quick coupling 254, and is connected with a high-pressure air source through the quick coupling 254.

The quick connector 254 includes an inner connector 2541 and an outer connector 2542. The outer joint 2542 is sleeved outside the inner joint 2541, and a space is reserved between the outer joint 2542 and the inner joint 2542.

The outer joint 2542 has a rear end connected to a rear end of the inner joint 2541, and the outer joint 2542 is provided with a plurality of slits 2543 along the axial direction thereof. By providing the outer joint 2542 with the plurality of slits 2543, the outer joint 2542 can have a certain elasticity.

The outer joint 2542 is externally provided with a screw 2544, and a nut 2545 is threadedly coupled to the screw 2544. The outer joint 2542 tapers in diameter from the leading end to the trailing end.

Specifically, in the process of connecting the quick coupling 254 with the air supply, first, the inner coupling 254 is inserted into a pipe orifice of the air supply, a gap exists between the inner coupling 2541 and the outer coupling 2542, the pipe orifice is located between the inner coupling 2541 and the outer coupling 2542, the nut 2545 moves along the axial direction of the outer coupling 2542 by rotating the nut 2545, and in the moving process of the nut 2545, the nut 2545 presses the outer coupling 2542, so that the gap between the outer coupling 2542 and the inner coupling 2541 is reduced. Thereby effecting a lock between the quick connector 254 and the air supply.

The outer joint 2542 is shorter in length than the inner joint 2541. This arrangement facilitates insertion of the quick connector 254 into the orifice of the air supply.

Nipple 2541 is provided with a groove and a sealing ring is provided on the groove. By providing the inner joint 2541 with a seal ring, the tightness of the connection between the inner joint 2541 and the gas source can be improved.

Referring to fig. 1 and 2, in the present embodiment, a connection relationship between the components of the hydraulic actuating apparatus is also provided.

The outlet end of the hydraulic oil tank 21 is communicated with the inlet end of the energy storage tank 22, the outlet end of the energy storage tank 22 is communicated with the inlet end of the pressure switch 23, the outlet end of the pressure switch 23 is communicated with the inlet end of the hydraulic motor 24, and the outlet end of the hydraulic motor 24 is communicated with the inlet end of the hydraulic oil tank 21.

When a hydraulic pump is arranged on the hydraulic circulation main oil path, the outlet end of the hydraulic oil tank 21 is communicated with the inlet end of the hydraulic pump, and the outlet end of the hydraulic pump is communicated with the inlet end of the energy storage tank 22.

The outlet end of the hydraulic pump assembly 252 is communicated with the energy storage tank 22 through a ball valve 3 and a three-way valve 4. The outlet end of the hydraulic pump assembly 252 is communicated with the inlet end of the ball valve 3, and the outlet end of the ball valve 3 is communicated with the first valve port of the three-way valve 4.

The second valve port of the three-way valve 4 is communicated with the inlet end of the energy storage tank 22, and the second valve port is communicated with the inlet end of the pressure switch 23.

The hydraulic pump unit 252 is equivalent to a bypass of a main oil path of the hydraulic circulation, and when hydraulic oil needs to be injected into the accumulator tank 22 through the hydraulic pump unit 252, the ball valve 3 is opened, and the hydraulic pump unit 252 is communicated with the accumulator tank 22. After the hydraulic oil is injected into the energy storage tank 22 through the hydraulic pump assembly 252, or when the hydraulic pump assembly 252 is not required to inject the hydraulic oil into the energy storage tank 22, the ball valve 3 is closed, and the hydraulic pump assembly 252 is disconnected from the energy storage tank 22.

An output shaft of the hydraulic motor 24 is connected to an input shaft of the engine 1 via a clutch. When the engine 1 is started, the output shaft of the hydraulic motor 24 is connected to the input shaft of the engine 1, and after the engine 1 is started, the output shaft of the hydraulic motor 24 is disconnected from the input shaft of the engine 1.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
