Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of hydraulic pump stations, and particularly relates to a remote control electric hydraulic pump station. BACKGROUND

[0002] A hydraulic pump station is a system composed of a hydraulic pump, a hydraulic motor, a hydraulic valve, an oil tank, an oil pipe and the like. The main function of the hydraulic pump station is to convert mechanical energy into hydraulic energy and transmit the hydraulic energy to the required position through a hydraulic system, so as to realize the action of various engineering machines. The hydraulic pump station is widely used in many industries such as metallurgy, petrochemical industry, machinery, ship, automobile and machine tool. For example, the brake system of a train, the control system of an automobile, the casting machine tool and the packaging machine in the metallurgical industry and the like.

[0003] Among them, in the field of locomotive derailment rescue and lifting, a hydraulic pump station is also used. For example, a Chinese patent with the publication number CN201257972Y discloses a hydraulic lifting device for a derailed locomotive, which comprises a rail bridge, a lifting device and a hydraulic pump station. Through the cooperation of the rail bridge, the lifting device and the hydraulic pump station, the derailed locomotive can be lifted, which can meet the use requirements to a certain extent.

[0004] However, the hydraulic pump station of the hydraulic lifting device still has some problems in use. For example, although the existing hydraulic pump station is provided with a moving mechanism, it cannot be applied to the track environment, that is, the moving mechanism of the hydraulic pump station cannot be used to approach the derailed locomotive, which will affect the normal use of the hydraulic pump station. Therefore, the existing hydraulic pump station generally relies on other track carriers for electric remote control movement, which is easy to increase the use cost of the hydraulic lifting device. In addition, for some locomotive derailment rescue and lifting work, multiple people are needed to carry the hydraulic pump station from the track carrier, which is easy to reduce the efficiency of locomotive derailment rescue and lifting.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a remote control electric hydraulic pump station.

DETAILED DESCRIPTION

[0047] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0048] like Figures 1 to 12 As shown, a remote-controlled electric hydraulic pump station according to one embodiment of the present invention includes a hydraulic pump station body 1, a convertible mechanism 2, a cross-track mechanism 3, and a generator box 4.

[0049] The hydraulic pump station body 1 is equipped with a battery and a control box. The battery is electrically connected to the control box. The battery is used to supply power to the control box, drive motor and other equipment. The control box is used to control the operation of the drive motor.

[0050] In addition, a wireless transmission unit is installed in the control box, which is connected to a remote control. Operators can control the operation of the drive motor remotely, thereby enabling the hydraulic pump station body 1 to move on the track, which is convenient for operation.

[0051] Specifically, the hydraulic pump station body 1 is equipped with handrails to facilitate the movement of the hydraulic pump station body 1 by staff.

[0052] like Figures 1 to 12 As shown, the convertible mechanism 2 is fixedly connected to the bottom of the hydraulic pump station body 1. Through the convertible mechanism 2, the hydraulic pump station body 1 can move on the track without the aid of other vehicles, ensuring its normal operation and enabling the rescue and recovery of derailed locomotives. The convertible mechanism 2 also allows the hydraulic pump station body 1 to move on other surfaces, increasing its overall flexibility.

[0053] The convertible mechanism 2 includes a base 201, and several casters 202 are installed at the bottom of the base 201, which enables the hydraulic pump station body 1 to move on the ground and increases the flexibility of the hydraulic pump station body 1.

[0054] In addition, each of the two side walls of the base 201 has a receiving cavity 203, which is used to accommodate the mounting plate 204. The mounting plate 204 is installed inside the receiving cavity 203, and a pair of track wheels 205 are rotatably connected to the mounting plate 204. When the hydraulic pump station body 1 needs to be used on the track, the mounting plate 204 extends out of the receiving cavity 203 and engages the track wheels 205 on the track.

[0055] Specifically, the driving motor is installed on the mounting plate 204, the driving motor is connected with one of the track wheels 205, and the driving motor is electrically connected with the control box. The driving motor can drive one of the track wheels 205 to rotate, and thus the hydraulic pump station body 1 can move on the track.

[0056] In addition, the bottom wall of the accommodating cavity 203 is provided with a position-avoiding groove corresponding to the driving motor, and when the mounting plate 204 is accommodated in the accommodating cavity 203, the driving motor is arranged in the position-avoiding groove.

[0057] As shown in Figures 1 to 12 The mounting plate 204 is fixedly connected with a pair of connecting rods 206, and the connecting rods 206 are slidingly arranged in the base 201. The connecting rods 206 are used to mount the mounting plate 204 on the base 201, so that when the track wheels 205 are clamped on the track, the track wheels 205 can support the base 201.

[0058] The base 201 is provided with a pair of pressure cavities 207 corresponding to the pair of mounting plates 204, and the pressure cavities 207 are used to accommodate the connecting rods 206. When the pressure cavities 207 are filled with gas, the mounting plate 204 can be pushed out, so that the track wheels 205 can be clamped on the track, and the hydraulic pump station body 1 can move on the track without the aid of other track carriers.

[0059] In addition, one end of the connecting rod 206 located in the pressure cavity 207 is connected with a force receiving plate 208. When the pressure cavity 207 is filled with gas, the gas has an acting force on the force receiving plate 208, and thus the mounting plate 204 can be pushed out from the accommodating cavity 203, the length of the base 201 as a whole is expanded, the track wheels 205 can be clamped on the track, and the hydraulic pump station body 1 can move on the track, so as to ensure the subsequent normal use of the hydraulic pump station body 1.

[0060] Specifically, the force receiving plate 208 is connected with an elastic rope between the inner wall of the pressure cavity 207. When the pressure cavity 207 is not filled with gas, the mounting plate 204 is re-stored in the accommodating cavity 203 under the action of the elastic rope, so as to reduce the volume of the hydraulic pump station body 1 as a whole.

[0061] In addition, the base 201 is provided with a pair of gas discharge pipes in communication with the pair of pressure cavities 207, and the gas discharge pipes are provided with a first control valve. When the first control valve is opened, the gas in the pressure cavities 207 is discharged through the gas discharge pipes, so as to reduce the gas capacity and pressure in the pressure cavities 207. When the gas in the pressure cavities 207 is completely discharged, the force receiving plate 208 is pulled by the elastic rope, so that the mounting plate 204 can be stored in the accommodating cavity 203.

[0062] As shown in Figures 1 to 12As shown, the base 201 is provided with a pair of air inlet cavities 209, and a high-pressure air pump 210 is installed in each air inlet cavity 209. The high-pressure air pump 210 is electrically connected to the control box, and a three-way pipe is connected to the gas outlet of the high-pressure air pump 210. One end of the three-way pipe is connected to a gas conveying pipe, and the gas conveying pipe is in communication with the pressure cavity 207. When the high-pressure air pump 210 is running, the high-pressure air pump 210 will extract the external gas and convey the gas into the pressure cavity 207, so that the gas capacity in the pressure cavity 207 is increased, and the gas pressure is increased, so as to be able to push out the mounting plate 204.

[0063] Preferably, a second control valve is installed on the gas conveying pipe for controlling the on-off of the gas conveying pipe.

[0064] Preferably, the base 201 is provided with a receiving groove 211 for accommodating the track-crossing mechanism 3.

[0065] As shown in the figure, Figures 1 to 12 the track-crossing mechanism 3 is installed in the receiving groove 211, and the track-crossing mechanism 3 is used to lift the hydraulic pump station body 1 and to cross the track, so as to reduce the burden of manual carrying and improve the efficiency of the locomotive derailment rescue recovery.

[0066] Preferably, the track-crossing mechanism 3 includes a bottom plate 301, which is accommodated in the receiving groove 211 and is used to connect a supporting plate 303, a first side skirt 304 and a second side skirt 306. A telescopic cylinder 302 is installed in the base 201, and the free end of the telescopic cylinder 302 is connected to the bottom plate 301. The telescopic cylinder 302 is used to control the movement of the bottom plate 301. When the hydraulic pump station body 1 needs to be jacked up, the telescopic cylinder 302 is elongated, so that the supporting plate 303 is as close as possible to the track ground, so that the track-crossing mechanism 3 can better jack up the hydraulic pump station body 1, and the track-crossing operation of the hydraulic pump station body 1 is realized.

[0067] Preferably, when the telescopic cylinder 302 is elongated, the distance between the supporting plate 303 and the ground is less than the distance between the universal wheel 202 and the ground, that is, when the hydraulic pump station body 1 is jacked up, the hydraulic pump station body 1 can smoothly realize the track crossing.

[0068] In addition, the bottom plate 301 is connected to the supporting plate 303 on the lower side, and the supporting plate 303 is used to bear the gas pressure, so as to jack up the hydraulic pump station body 1. The outer side of the supporting plate 303 is provided with the first side skirt 304, and the first side skirt 304 is connected to the bottom plate 301. The first side skirt 304 is used to block the gas flow. Through the cooperation of the supporting plate 303 and the first side skirt 304, the gas inside the first side skirt 304 can jack up the bottom plate 301 and the supporting plate 303, and then the hydraulic pump station body 1 can be jacked up.

[0069] Preferably, when the track-crossing mechanism 3 is used, the gas flow diagram is as shown in the figure. Figure 6 ​

[0070] Specifically, the other interface of the tee pipe is connected with an air inlet pipe 305, one end of the air inlet pipe 305 is arranged between the supporting plate 303 and the first side skirt 304. When the high-pressure air pump 210 is running, the high-pressure air pump 210 can deliver air to the space between the supporting plate 303 and the first side skirt 304 through the air inlet pipe 305, and the air has a force on the bottom plate 301 and the supporting plate 303, thereby achieving the jacking of the hydraulic pump station body 1, so that the hydraulic pump station body 1 can be suspended at a certain height to realize the action of crossing the track, without the need for multiple workers to manually lift, which not only reduces the burden on the workers, but also improves the efficiency of subsequent locomotive derailment rescue and recovery.

[0071] Preferably, a third control valve is installed on the air inlet pipe 305 for controlling the on-off of the air inlet pipe 305. When the track crossing mechanism 3 is running, the track crossing mechanism 3 can jack up the hydraulic pump station body 1, and the jacking height of the universal wheel 202 is greater than the height of the track, that is, Figure 12 as shown in the state, so as to realize the smooth crossing of the hydraulic pump station body 1.

[0072] As Figures 1 to 12 shown, the bottom plate 301 is connected with a second side skirt 306, and the second side skirt 306 is arranged outside the first side skirt 304. The second side skirt 306 can further block the air to ensure that the air can jack up the bottom plate 301 and the supporting plate 303, and at the same time, the second side skirt 306 can also protect the first side skirt 304.

[0073] Preferably, the first side skirt 304 and the second side skirt 306 are both made of nylon rubber cloth material, which can greatly improve the service life of the first side skirt 304 and the second side skirt 306, thereby reducing the probability of damage of the first side skirt 304 and the second side skirt 306 caused by friction with the track.

[0074] Preferably, the base 201 is provided with an exhaust cavity 212 for temporarily storing air. The bottom plate 301 is connected with an exhaust pipe 307, one end of the exhaust pipe 307 is arranged between the first side skirt 304 and the second side skirt 306, and the other end of the exhaust pipe 307 is arranged in the exhaust cavity 212. When the hydraulic pump station body 1 is jacked up, part of the air between the first side skirt 304 and the second side skirt 306 can enter the exhaust cavity 212 through the exhaust pipe 307, instead of being discharged only through the lower side of the second side skirt 306, that is, Figure 6 as shown in the air flow direction.

[0075] By arranging the exhaust pipe 307, the air flow direction can be changed, and the air intensity of the air discharged from the bottom of the second side skirt 306 to the outside can be weakened, thereby avoiding the probability of blowing up the track sand and gravel by high-intensity air, and greatly reducing the injury of the workers when operating the hydraulic pump station body 1 to cross the track.

[0076] In addition, after the hydraulic pump station body 1 is completed across the track, it is difficult to move on the ground through the universal wheel 202 due to the large amount of sand and stones near the track, so the hydraulic pump station body 1 can continue to be jacked up by the track-crossing mechanism 3 after being completed across the track, and the staff can hold the handrails and push the hydraulic pump station body 1 to move, so that the hydraulic pump station body 1 can reach the appropriate position for use.

[0077] As shown in Figures 1 to 12 , the hydraulic pump station body 1 is provided with a power generation box 4, which is used for recycling part of the gas discharged by the track-crossing mechanism 3, effectively avoiding resource waste.

[0078] Among them, the power generation box 4 is provided with a partition plate 401, and a filter cavity and a power generation cavity are formed between the partition plate 401 and the inner wall of the power generation box 4. The power generation box 4 is connected with a connecting pipe 402, and the filter cavity is connected with the exhaust cavity 212 in communication through the connecting pipe 402. The gas in the exhaust cavity 212 can enter the filter cavity through the connecting pipe 402.

[0079] In addition, a pair of filter screens 403 are installed in the filter cavity, which can filter the gas and avoid the presence of sand and stone particles in the gas, thereby avoiding the impact of the sand and stone particles on the blades 408 and greatly reducing the probability of damage to the blades 408.

[0080] Preferably, the mesh ratio of the pair of filter screens 403 is 1:2, which can improve the filtering effect of the filter screens 403 on the gas.

[0081] Specifically, the side wall of the power generation box 4 is hingedly connected with a cover door, which facilitates the staff to clean the sand and stone particles in the filter cavity.

[0082] In addition, the partition plate 401 is provided with a through hole 404, and the gas in the filter cavity can enter the power generation cavity through the through hole 404.

[0083] As shown in Figures 1 to 12 , a pair of net racks 405 are installed in the power generation cavity, and a gear box 406 and a generator 407 are respectively installed on the pair of net racks 405. The gear box 406 is in transmission connection with the generator 407, the generator 407 is in electrical connection with a storage battery, and the gear box 406 is connected with blades 408. The gas in the power generation cavity drives the blades 408 to rotate, and the blades 408 drive the generator 407 to generate electricity through the gear box 406. The power generated by the generator 407 is stored in the storage battery, which is used to supply power to the driving motor and the control box.

[0084] Among them, the side wall of the power generation box 4 is provided with an air outlet for discharging the gas in the power generation cavity.

[0085] Preferably, the power generation box 4 is arranged on the side of the hydraulic pump station body 1 away from the handrail, so as to avoid the influence of the discharged gas in the power generation cavity on the staff.

[0086] In use, when the hydraulic pump station body 1 needs to be used on the track, the high-pressure air pump 210 is controlled to operate, the high-pressure air pump 210 sucks external air, the air enters the pressure cavity 207 through the three-way pipe and the air conveying pipe, as the air capacity in the pressure cavity 207 increases, the air pressure becomes larger, the air has a force on the force plate 208, so that the connecting rod 206 and the mounting plate 204 are pushed out. When the mounting plate 204 is completely pushed out, the operation of the high-pressure air pump 210 is stopped, and the second control valve on the air conveying pipe is closed. At this time, the track wheel 205 can be clamped on the track, and the hydraulic pump station body 1 can be fixed on the track.

[0087] The staff operates the remote controller, the remote controller can send instructions to the control box, the control box controls the driving motor to operate, the driving motor drives one of the track wheels 205 to rotate, and then the hydraulic pump station body 1 can move on the track without the aid of other track carriers, so as to ensure that the hydraulic pump station body 1 can be normally used to rescue and lift the derailed locomotive.

[0088] If the hydraulic pump station body 1 needs to be moved to other positions for use, the high-pressure air pump 210 is controlled to operate, and the third control valve on the air inlet pipe 305 is opened, so that the high-pressure air pump 210 can convey air between the supporting plate 303 and the first side skirt 304 through the air inlet pipe 305. The air is blocked by the first side skirt 304 and the second side skirt 306, so that the air has a lifting force on the bottom plate 301 and the supporting plate 303, that is, an air cushion is formed at the bottom of the track crossing mechanism 3. Specifically, the air flow path is as shown in Figure 6 , and then the hydraulic pump station body 1 can be jacked up, so that the hydraulic pump station body 1 is suspended at a certain height, and the jacking height of the universal wheel 202 is greater than the height of the track.

[0089] The part of the air entering between the first side skirt 304 and the second side skirt 306 enters the exhaust cavity 212 through the exhaust pipe 307, instead of being discharged through the bottom of the second side skirt 306, so as to change the flow direction of the discharged air, weaken the intensity of the air discharged outward from the bottom of the second side skirt 306, and thus avoid the probability of sand and stones on the track being blown up by high-intensity air, greatly reducing the injury of the staff when operating the hydraulic pump station body 1 to cross the track.

[0090] The gas in the exhaust cavity 212 enters the filter cavity through the connecting pipe 402, is filtered by the filter screen 403 to remove sand particles in the gas, and enters the power generation cavity through the through hole 404.

[0091] The staff holds the handrail and pushes the hydraulic pump station body 1 to move, so that the hydraulic pump station body 1 can realize the cross-rail action without the need for multiple staff to manually lift the cross-rail, which not only reduces the burden of the staff, but also improves the subsequent locomotive derailment rescue recovery efficiency.

[0092] When the hydraulic pump station body 1 completes the cross-rail, if there are many sandstones near the track, it is difficult to move on the ground through the universal wheel 202, the cross-rail mechanism 3 can be used to continue to lift the hydraulic pump station body 1, thereby greatly reducing the moving resistance of the hydraulic pump station body 1 on the road near the track, so that the hydraulic pump station body 1 can be quickly moved into position, facilitating the subsequent use of the hydraulic pump station body 1.

[0093] It will be obvious to a person skilled in the art that, without departing from the spirit or essential characteristics of the application, the present application can be implemented in other specific forms. The present examples are therefore to be considered in all respects as illustrative and not restrictive, the scope of the application being indicated by the appended claims rather than by the specification as such. Any reference signs in the claims should not be construed as limiting the scope of the claims.

[0094] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
