[0002] As the main production equipment of coal mines, the rapid and efficient withdrawal and installation of hydraulic supports is an important link to ensure the continuation of mine production. In underground coal mines, after the comprehensive mining face is mined, the hydraulic supports and other equipment on the working face need to be withdrawn to the well, or transported to a new comprehensive mining face for installation. The speed of their installation, removal and transportation is an important link to improve the efficiency of coal mining.

[0003] In the related art, the hydraulic traction device can be used to complete the processes of pulling the hydraulic support back and installing, but during the pulling process, the hydraulic traction device usually needs to have functions such as telescopic and rotating to adapt to the complex underground working conditions.

[0007] The receiver includes a second microcontroller, multiple interfaces, and a wireless receiving module; the wireless receiving module communicates with the wireless sending module, the wireless receiving module is connected to the second microcontroller, the second microcontroller is connected to multiple interfaces, and each of the interfaces is connected to the solenoid valve of the hydraulic support via a connecting signal line.

[0022] The present invention is further described in detail below through the accompanying drawings and specific implementation methods.

[0023] like Figure 1-2 As shown, an embodiment of the utility model provides a hydraulic support adjustment device, including a remote controller 1 and a receiver 2, wherein the receiver is arranged on the hydraulic support, and the remote controller includes a housing 101 and a control panel 102; a control circuit is arranged inside the housing, and the control circuit includes a first microcontroller 103, a power supply 104, a serial port display screen 105, a wireless transmission module 106, and a plurality of dip switches;

[0024] The receiver includes a second microcontroller 201, multiple interfaces 202, and a wireless receiving module 203; the wireless receiving module communicates with the wireless transmitting module, the wireless receiving module is connected to the second microcontroller, the second microcontroller is connected to multiple interfaces, and each interface is connected to the solenoid valve of the hydraulic support through a connecting signal line. It should be noted that the number of the code switches corresponds to the number of interfaces. When the user turns the code switch to send a control signal to the receiver, a solenoid valve is correspondingly controlled. The solenoid valve used is a conventional hydraulic solenoid valve, which is used to control the hydraulic flow direction.

[0025] This type of solenoid valve has a sealed cavity with through holes at different positions. Each hole leads to a different oil pipe. The valve is in the middle of the cavity and there are two electromagnets on both sides. The valve body will be attracted to the side where the magnet coil is energized. The movement of the valve body is controlled to block or leak different oil drain holes. The oil inlet hole is normally open, and the hydraulic oil will enter different oil drain pipes, and then the hydraulic shift device will be driven by the oil pressure. In this way, the current of the electromagnet is controlled to control the mechanical movement of the hydraulic shift device.

[0026] like Figure 3 As shown, each of the dip switches is respectively connected to the first microcontroller, and the first microcontroller is connected to the wireless transmission module and the serial port display screen; the serial port display screen, the first microcontroller and the wireless transmission module are respectively connected to the power supply; further, the first microcontroller and the serial port display screen are connected through an interface conversion chip. Among them, the interface conversion chip can be model KY3232. The chip U5 in the figure is an interface conversion chip, which supports; two-way conversion, this application can use one of them, the T1IN pin and the R1IN pin are respectively connected to the TTL serial port of the main control chip, and the T1OUT pin and the R1OUT pin are connected to the RS232 serial port display screen.

[0027] If you choose a display screen with a TTL interface, you do not need to use an adapter chip and can directly connect the display screen to the signal output pin of the microcontroller.

[0028] like Figure 4As shown, at least 12 dial switches are provided, and the 12 dial switches at least include P1-left push extension and retraction; P2-left arm rise and fall; P3-left slide rail extension and retraction; P4-left arm left and right swing; P5-front wheel rise and fall; P6-left arm extension and retraction; P7-rear wheel rise and fall; P8-right arm extension and retraction; P9-right slide rail extension and retraction; P10-right arm left and right swing; P11-right push extension and retraction; P12-right arm rise and fall.

[0029] The first microcontroller and the second microcontroller both use STM32F series chips, specifically STM32F103ZET6.

[0030] Each of the above-mentioned dip switches is provided with three contacts arranged side by side. Taking one of the dip switches as an example, the first contact (controlling the left push extension) and the third contact (controlling the left push contraction) at both ends of the dip switch P1 are respectively connected to the signal input pins PD0 and PD1 of the first microcontroller, and the second contact in the middle is connected to the 3.3V high level. It should be noted that the first contact and the third contact of each dip switch need to be connected to a pull-down resistor, and the pull-down resistor is grounded. When the dip switch P1 is moved to the first contact, the signal input pin PD0 is turned on at a low level. At this time, the first microcontroller sends a command to control the left push extension to the wireless transmission module. After the wireless receiving module of the receiver receives this command, the second microcontroller controls the electromagnetic valve connected to the corresponding interface to open through the corresponding interface, and at this time controls the extension of the left push arm of the hydraulic support; similarly, when other dip switches are moved, remote control can be achieved according to the above process.

A guardrail 301 is provided above the housing, and a shoulder strap is tied to the guardrail. The portability and stability during remote control operation can be improved.

[0032] It should be noted that the control programs involved in the main control chip of this application can all adopt existing technologies. The main innovation of this application lies in the peripheral circuit structure of the main control chip and does not involve improvements to the program.

[0033] Obviously, the above embodiments are only examples for clear explanation, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from them are still within the protection scope of the invention of the utility model.
