Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic support resistance monitoring, in particular to a novel hydraulic support resistance monitoring instrument. Background Art

[0002] As an important equipment in modern mining, the stability and safety of hydraulic supports are directly related to the safety and efficiency of mining production. In mining operations, the resistance monitoring of hydraulic supports is a key link to ensure its normal operation, and is also an important means to prevent accidents and improve production efficiency.

[0003] Most traditional hydraulic support resistance monitoring instruments use electronic sensors. Although they can meet basic monitoring needs to a certain extent, they have many shortcomings. For example, with the expansion of mining scale and the increase of operating depth, the monitoring requirements for hydraulic support resistance are getting higher and higher, and the problem of reduced acquisition accuracy may occur. The force of hydraulic support is a manifestation of mine pressure. The mine pressure analysis is based on the working cycle of the support. The initial support force and the final resistance in the cycle are crucial to the mine pressure analysis. The current station-type equipment is not accurate in monitoring. In addition, the new hydraulic support resistance monitoring instrument should also consider humanized design to facilitate miners' operation and maintenance. For example, the instrument should have an intuitive display screen that can display the resistance data of the support in real time; the traditional station-type hydraulic support resistance collector has the problem of inability to accurately collect data due to factors such as a single timing collection mode, a short hydraulic support frame moving process time (about 30s), power consumption, and data storage. Therefore, the development of a new hydraulic support resistance monitoring instrument has become an urgent problem to be solved in the current field of mine safety technology.

[0025] In order to further explain the scheme adopted by the utility model to achieve the predetermined purpose, the following is a detailed description of the specific implementation, structure, features and functions of a new type of hydraulic support resistance monitoring instrument proposed according to the utility model in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures, or characteristics in one or more embodiments may be combined in any suitable form.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0027] The specific scheme of a novel hydraulic support resistance monitoring instrument provided by the utility model is described in detail below in conjunction with the accompanying drawings.

[0028] Example:

[0029] The main application scenarios of this utility model are:

[0030] Hydraulic support resistance monitoring is one of the important technical means to ensure safe and efficient production in coal mines. Among them, accurate monitoring of the working cycle of the hydraulic support and its initial support force and final resistance is particularly critical. Therefore, it is necessary to design a new type of hydraulic support resistance monitoring instrument to monitor the changes in the hydraulic support resistance.

[0031] See also Figure 1, which shows a first cross-sectional view of a new type of hydraulic support resistance monitoring instrument provided by an embodiment of the utility model. The hydraulic support resistance monitoring instrument is mainly composed of a circuit board 1, an explosion-proof shell, a button and a pressure sensor 8, wherein the explosion-proof shell includes a lower shell, a battery compartment 2, a metal panel 6 and a fireproof nameplate 4 (the explosion-proof shell is not marked in the figure); the circuit board 1 and the button are fixed on the metal panel 6; the button includes a power switch button 7 and a function button; the power switch button 7 is used to control the power switch of the hydraulic support resistance monitoring instrument; the function button is used to control the working mode of the hydraulic support resistance monitoring instrument; the pressure sensor 8 is used to measure the support resistance.

[0032] like Figure 2 As shown, the circuit board 1 is integrated with a display module 18, a main control module 11, a Bluetooth module 12, a storage module, a sensor drive module 14, a sensor interface 15, a real-time clock 16 and a backup power supply 17; wherein the display module 18 is a liquid crystal display screen 10, the main control module 11 is an MCU, and the Bluetooth module 12 is a Bluetooth 5.0 wireless communication module for wireless communication with a terminal; the storage module is a storage 13, and the backup power supply 17 is a real-time clock backup power supply. It should be noted that there is more than one sensor interface 15, and the implementer can adjust the number of sensor interfaces 15 according to actual conditions, wherein the sensor interface 15 is used to connect the pressure sensor 8, and the sensor drive module 14 is used to drive the pressure sensor 8 connected to the circuit board 1; the collected resistance data is stored in the storage 13.

[0033] The explosion-proof shell is mainly composed of a lower shell, a battery compartment 2, a metal panel 6, and a fireproof nameplate 4. The lower shell is fixed with a glue-sealed battery compartment, wherein the battery in the battery compartment 2 is a lithium battery 3; a hole is opened at the lower side wall plate of the lower shell and at least two pressure sensors 8 are fixed thereto, and the metal panel 6 is fixed with a circuit board 1 and buttons; the fireproof nameplate 4 is tightly connected to the metal panel 6 by glue. Preferably, an ABS fireproof nameplate is selected in the embodiment of the present application, and the implementer can choose according to actual needs.

[0034] like Figure 3 and Figure 4 As shown, the buttons include a power switch button 7 and a function button; an indicator light 19 is also included to indicate the working state of the hydraulic support resistance monitoring instrument. The power switch button 7 can be used to control the power supply of the entire hydraulic support resistance monitoring instrument, and the function button mainly controls the working mode of the hydraulic support resistance monitoring instrument. Specifically: single-click the function button to start the dynamic high-speed acquisition working mode; double-click the function button continuously to start the zero-point calibration working mode; long press the function button to start the working mode in which the Bluetooth module 12 is connected to the terminal; it should be noted that the terminal here can be a mobile terminal, such as a mobile phone. A circle of silicone sealing ring 5 is pressed between the lower shell and the metal panel 6, which is tightly connected by screws 9.

[0035] Among them, the pressure sensor 8 is composed of a mining KJ10 connector, a resistance strain gauge, a terminal block, a wire, and a male plug. The model of the male plug can be selected by the implementer according to actual conditions. Preferably, an X2.54mm male plug is used in the embodiment of the utility model to convert the bracket resistance into an analog electrical signal, which is then collected by the sensor drive module 14.

[0036] During use, it is necessary to connect the hydraulic support column oil pipe and the pressure sensor connector, and then use the Bluetooth module 12 to connect the terminal, and set the relevant parameters of the hydraulic support resistance monitoring instrument at the terminal, mainly the collection frequency and collection duration, etc. It should be noted that the relevant parameters of the hydraulic support resistance monitoring instrument have initial values, and the implementer can set them by himself at the terminal according to actual needs; in the working state, before the worker performs the hydraulic support frame moving operation, he clicks the function button to start the dynamic high-speed collection working mode, so as to realize the accurate collection of the final resistance and initial support force of the hydraulic support during the frame moving process. The dynamic high-speed collection working mode can be automatically converted to the static low-speed collection working mode after T seconds. The static low-speed collection interval device enters the low-power sleep mode.

[0037] It should be noted that the difference between the dynamic high-speed acquisition working mode and the static low-speed acquisition working mode is that the dynamic high-speed sampling period and the static low-speed sampling period are different, that is, the sampling frequency is different, among which the sampling frequency of the dynamic high-speed acquisition working mode is higher than the sampling frequency of the static low-speed acquisition working mode.

[0038] Among them, the duration T of the dynamic high-speed acquisition working mode, the dynamic high-speed sampling period t1, and the static low-speed sampling period t2 can all be set through the terminal; when the hydraulic support resistance monitoring instrument is working, the dynamic high-speed acquisition working mode is switched as follows Figure 5 As shown in the figure, the time interval between the vertical dotted lines corresponding to the start and end of the dynamic high-speed acquisition working mode is the dynamic high-speed acquisition working mode duration T, which can be set by the terminal and is preset.

[0039] To sum up, in traditional equipment, the acquisition frequency can be set through the terminal before installation, but after setting, it can only work at the set frequency during the working process, and there is no button for switching the working mode. The device in this application presets two different working modes and switches with one button through the function button, which can realize the switching of the working mode during the working process, making the collected resistance data more accurate.

The above is a description of a specific embodiment of this specification. In addition, the processes depicted in the accompanying drawings do not necessarily require the specific order or continuous order shown to achieve the desired results.
