For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] Example 1
[0037] This embodiment provides an integrated liquid supply system transport device, combined with Figure 1 , Figure 2 and Figure 3 As shown, it includes a plurality of flatbed trolley assemblies 101 connected in sequence, each of the flatbed trolley assemblies 101 includes:
[0038] The vehicle body 201 has a receiving surface for carrying the integrated liquid supply system component 102; a medium transmission path, a first end of which is connected to the medium outlet of the integrated liquid supply system through a valve assembly, and a second end of which is connected to a medium collection point 304, the controlled end of the valve assembly is connected to a host computer for communication, the valve assembly receives a control instruction sent by the host computer to achieve conduction or cutoff, and the valve assembly is turned on; a reversing valve 206 (as can be seen from the figure, for the reversing valve, its number should be the same as the sum of the number of hydraulic motors 202 and hydraulic support cylinders 307, that is, each reversing valve 206 is connected to a hydraulic motor 202 or a hydraulic support cylinder 307), and its liquid inlet end is connected to the medium collection point 304; The hydraulic motor 202 is installed at the set position of the vehicle body 201, and its first end and second end are respectively connected to the first end and the second end of the reversing valve 206. The hydraulic motor 202 adjusts the direction and speed of its driving output shaft according to the flow direction of the medium and the amount of the flowing medium; the transmission mechanism is arranged at the bottom of the vehicle body 201 (the structure shown in the figure, the transmission mechanism can include two, and the two transmission structures are symmetrically arranged near the two ends of the vehicle body 201), which includes a driving wheel 203; the rotating shaft of the driving wheel 203 is connected to the driving output shaft of the hydraulic motor 202, and the driving wheel 203 rotates or stops under the drive of the driving output shaft, thereby driving the flatbed vehicle assembly 101 to move or stop. Among them, the rotating shaft of the driving wheel 203 can be connected to the output shaft of the hydraulic motor through the rack 205, and at this time, the outer wall of the driving output shaft of the hydraulic motor and the outer wall of the rotating shaft of the driving wheel 203 are formed with meshing teeth. In the above, the medium can be hydraulic oil.
[0039] In the above scheme, when the valve assembly is turned on, the medium in the integrated liquid supply system can be transmitted to the medium collection point 304 through the valve assembly. Each reversing valve 206 is connected to the medium collection point. After the medium enters the reversing valve 206, the medium flow direction is different, which corresponds to the different operation modes of the hydraulic support cylinder 307 / hydraulic motor 202. For the hydraulic support cylinder 307, its working modes are extension and retraction, respectively. For the hydraulic motor 202, its working modes correspond to the forward rotation and reverse rotation of its drive output shaft. When there is no medium flow in the reversing valve 206, it corresponds to the hydraulic support cylinder 307 not moving or the hydraulic motor 202 not moving. When the hydraulic motor 202 rotates forward and reversely, it can drive the flatbed assembly 101 forward or backward through the driving wheel 203. When the hydraulic motor 202 does not move, it can control the flatbed assembly 101 to stop.
[0040] In the above scheme, the integrated fluid supply system provides a medium for the hydraulic motor 202, thereby driving the hydraulic motor 202 to rotate forward, reverse or stop, and can drive the driving wheel 203 to rotate forward, reverse or stop. Since each flatbed vehicle assembly 101 is self-driven and does not need to be pulled by the front flatbed vehicle assembly, the rope breaking is avoided when going uphill, and when going downhill, the rotation of the driving wheel 203 is limited by the driving of the hydraulic motor 202 and cannot accelerate and move by itself, thereby avoiding the occurrence of landslides, thereby improving the safety and stability of the integrated fluid supply system transportation process.
[0041] In the above scheme, if Figure 2 As shown, the transmission mechanism may further include a traction wheel 204, the rotating shaft of the driving wheel 203 and the rotating shaft of the traction wheel 204 are both configured with a gear structure, and the two gear structures are meshed through a rack; the traction wheel 204 rotates or stops synchronously with the driving wheel 203. The transmission mechanism moves through two wheel structures, which can improve the stability during the movement.
[0042] In addition, in the above technical solution provided in this embodiment, the integrated fluid supply system itself is used to provide medium for the hydraulic support cylinder 201, and the improvement point of the present application is to add a hydraulic motor 202, and each hydraulic motor 202 also relies on the integrated fluid supply system for fluid supply. Therefore, the working mode of the hydraulic support cylinder 307 is no longer described in detail in the following solution of the present application. Please refer to the prior art solution.
[0043] Furthermore, if Figure 3 As shown, in the integrated liquid supply system transport device, the valve assembly includes:
[0044] The motor 301, whose controlled end is connected to the host computer as the controlled end of the valve assembly; the speed of the output shaft of the motor 301 corresponds to the control instruction; the pump body 302, the pump body 302 can be implemented by an emulsifying pump, whose liquid inlet is connected to the medium outlet of the integrated liquid supply system as the first end of the medium transmission path, and whose driven end is connected to the output shaft of the motor 301; the pump body 302 extracts the medium from the medium outlet of the integrated liquid supply system under the drive of the motor 301; the unloading valve 303, whose liquid inlet is connected to the liquid outlet of the pump body 302, and whose liquid outlet is connected to the medium collection point 304 as the second end of the medium transmission path. For the motor 301, the speed of its output shaft can be controlled by the motor controller, and the host computer can be operated by the operator. The host computer can automatically or manually determine the theoretical speed of the motor 301, and then the host computer can convert it into a corresponding signal and send it to the motor controller, and the motor controller can directly control the output shaft to rotate at the corresponding speed according to the received signal.
[0045] Preferably, the motor 301 is a variable frequency motor. When the motor 301 is a variable frequency motor, the speed of its output shaft can be adjusted within a relatively large range, so that the working frequency of the pump body 302 can also change. When the working frequency of the pump body 302 changes, the amount of medium entering the medium collection point changes accordingly, so that the hydraulic motor 302 can also have different amounts of medium entering its interior, and the speed of the driving output shaft of the hydraulic motor 202 changes accordingly, thereby controlling the travel speed of the flatbed vehicle assembly 101. The variable frequency motor, unloading valve, etc. used in the above scheme can be implemented using existing devices in the prior art.
[0046] In addition, the integrated liquid supply system transport device in the above scheme, such as Figure 3 As shown, a safety valve 305 may also be included, and the safety valve 305 is arranged between the liquid outlet of the pump body 302 and the liquid inlet of the unloading valve 303. The liquid inlet end of the safety valve 305 is directly connected to the liquid outlet of the pump body 302. If the medium is blocked in the system or the pressure in the medium transmission path is too high due to other reasons and exceeds the opening threshold of the safety valve 305, the safety valve 305 will open automatically to release the medium. The liquid outlet of the safety valve 305 can be connected to a medium recovery box, etc., so that the released medium can be further recovered.
[0047] Furthermore, the above integrated liquid supply system transport device may further include an accumulator 306, the inlet end of the accumulator 306 being connected to the medium collection point 304. The accumulator 306 can offset the pressure change caused by the flow velocity or flow fluctuation during the medium transmission process, that is, if the medium flow suddenly increases, the accumulator 306 can absorb the pressure increase caused by the sudden increase of the medium, and when the medium flow suddenly decreases, the accumulator 306 can release energy to offset the pressure fluctuation caused by the sudden decrease of the medium flow.
[0048] In the above scheme, if Figure 4 As shown, in any two adjacent body parts 201 of the flatbed truck, a first support plate 401 extends from the first body part, and a first mounting hole is provided on the first support plate 401; a second support plate 402 extends from the second body part, and a second mounting hole is provided on the second support plate 402; the first support plate 401 and the second support plate 402 are arranged opposite to each other and the first support plate 401 is located below the second support plate; the first mounting hole is aligned with the second mounting hole and connected by a locking member. Figure 4As shown, the locking member is a pin 403, and a baffle 404 is provided at one end of the pin 403, and the baffle 404 is limited on the side of the second support plate 402 facing away from the first support plate 401. The first support plate 401 and the second support plate 402 can both slide axially along the pin 403. Since the weight of the components of the integrated liquid supply device supported on the two adjacent vehicle bodies is different, when the hydraulic motor 202 is driven, the lifting or lowering speed of the two vehicle bodies 201 is different. The two vehicle bodies 201 are connected by the pin 403, and there is enough gap between the first support plate 401 and the second support plate 402, which can buffer the displacement difference caused by the lifting speed of the two vehicle bodies 201, thereby ensuring the normal use of multiple flatbed vehicle assemblies 101.
[0049] Example 2
[0050] This embodiment provides a control system for an integrated liquid supply system transport device, such as Figure 5 As shown, it includes an integrated liquid supply system transportation device and a host computer 501, wherein the host computer 501 is used to communicate with the hydraulic support controller 503, obtain the liquid supply parameters of the hydraulic support, obtain the theoretical moving speed of the integrated liquid supply system according to the liquid supply parameters, generate a control instruction according to the theoretical moving speed and send it to the controlled end of the valve component 502 of the transportation device; the controlled end of the valve component 502 receives the control instruction sent by the host computer 501, opens or closes according to the control instruction, drives the flatbed vehicle component 101 to move to control the transportation device to move according to the theoretical moving speed.
[0051] The host computer 501 may be in the monitoring center of the fully mechanized mining face, and the hydraulic support controller 503 and the hydraulic support may be in a one-to-one relationship or a one-to-N relationship. The hydraulic support controller 503 can control the hydraulic support to move according to the coal mining process, so the hydraulic support can determine the amount of medium required by the cylinder of each hydraulic support at each moment. The integrated liquid supply system is a device for providing medium to the hydraulic support cylinder. The distance between adjacent support cylinders is known, and the rate at which the integrated liquid supply system provides medium to the hydraulic support can be determined. Therefore, the moving speed of the integrated liquid supply system can be determined according to the medium demand of each hydraulic support cylinder. When the moving speed of the integrated liquid supply system is determined, the moving speed of the transport device is determined.
[0052] Preferably, the control instruction generated by the host computer includes a motor speed value; the motor in the valve assembly rotates according to the motor speed value, and can drive the pump body to extract a theoretical amount of medium from the integrated liquid supply system, and the theoretical amount of medium is evenly distributed to multiple hydraulic motors, and the output drive shaft of the hydraulic motor drives the drive wheel to move at the theoretical moving speed. The host computer is also used to receive the moving speed of the vehicle body sent by the speed sensor in the transport device; if the difference between the moving speed and the theoretical moving speed exceeds the set threshold, the host computer adjusts the control instruction to increase or decrease the motor speed value so that the difference between the moving speed of the transport device and the theoretical moving speed is less than or equal to the set threshold. In other words, the host computer can determine the moving speed range of the integrated liquid supply system based on the information fed back by the hydraulic support controller. When the transport device is moving, the speed of the transport device is detected in real time. When it is found that it is no longer within the theoretical range, assuming that it exceeds 10% of the theoretical value or is lower than 10% of the theoretical value, the speed of the transport device can be further controlled to adjust. Preferably, when the motor in the valve assembly is selected as a variable frequency motor, the host computer 501 increases or decreases the motor speed value by adjusting the running frequency of the motor.
[0053] Here are some examples:
[0054] Assuming that at the current moment, the transport device needs to supply fluid to the i-th hydraulic support, and through the feedback information from the hydraulic support controller 503, it is determined that the amount of medium required by the i-th hydraulic support at the current moment is Qi, and the medium flow rate when the integrated fluid supply system outputs medium to the hydraulic support cylinder is Vi, then from the current moment on, the moving speed of the transport device should be zero, because it needs to stop to supply medium to the cylinder of the i-th hydraulic support, and the stopping time is: Ti=Qi / Vi. After providing medium to the i-th hydraulic support cylinder, it needs to move to the position of the (i+1)-th hydraulic support cylinder. The distance between two adjacent hydraulic support cylinders is L. The moving speed of the transport device is preferably V according to historical experience (the moving speed of the transport device can also be determined according to the time node when the (i+1)-th hydraulic support needs to provide medium, for example: it is necessary to travel from the position of the i-th hydraulic support cylinder to the position of the (i+1)-th hydraulic support cylinder within the time T, and the driving speed can be determined according to the distance and time). The speed of the driving wheel can be determined according to the moving speed V of the transport device and the circumference of the driving wheel, the speed of the hydraulic motor can be determined according to the speed of the driving wheel, and the amount of medium required by the hydraulic motor can be inferred according to the speed of the hydraulic motor. The sum of the amount of medium required by each hydraulic motor is the amount of medium that needs to be input to the medium collection point (assuming that no hydraulic support cylinder needs medium in this process), and then the working frequency of the emulsification pump can be determined, thereby obtaining the working frequency of the variable frequency motor. After a series of analyses, the host computer can generate control instructions, and the control instructions are sent to the controlled end of the valve assembly to control the transport device to move at the moving speed V. When the transport device travels to the (i+1)th hydraulic support cylinder, it can stop to provide medium for the (i+1)th hydraulic support cylinder. The stopping time can be the same as when the i-th hydraulic support cylinder provides medium, which will not be described in detail. In summary, the host computer can control and adjust the running speed of the transport device from the first hydraulic support to the last hydraulic support in real time to meet the liquid supply needs of each hydraulic support. At the same time, since each flatbed car assembly is driven by itself and does not require the front flatbed car assembly to pull and move, the rope breaking is avoided when going uphill, and when going downhill, the rotation of the driving wheel is restricted by the driving limit of the hydraulic motor and cannot accelerate and move by itself, thereby avoiding the occurrence of landslides, which improves the safety and stability of the integrated liquid supply system transportation process.
[0055] Example 3
[0056] This embodiment provides an integrated liquid supply device, including an integrated liquid supply system and a control system of the integrated liquid supply system transportation device described in any one of the schemes in Example 2, wherein different components of the integrated liquid supply system are sequentially arranged on the body of different flatbed truck components of the transportation device.
[0057] By controlling the moving speed of the transport device through the control system, it can be ensured that the integrated fluid supply system provides medium to each hydraulic support cylinder according to the set fluid supply requirements. At the same time, since the movement process of the transport device is to supply fluid to the hydraulic motor through the integrated fluid supply system, the drive output shaft of the hydraulic motor provides power to the drive wheel to drive the flatbed vehicle assembly to move, thus effectively avoiding the situation in the prior art that the transport device breaks the rope when going uphill and slides downhill, and can operate safely even in a lane with poor stability.
[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
