Description

Technical Field

[0001] The present invention relates to the technical field of supporting force detection devices, and in particular to a supporting force detection device for a hydraulic support. Background Art

[0002] Hydraulic supports are important supporting equipment in coal mines to prevent collapse and maintain the safety of the working space. When the hydraulic supports are working, the supporting force of the hydraulic supports is directly related to the stability of the roof. Therefore, in order to always know the supporting force of the hydraulic supports, the staff generally use support force detection devices to monitor the hydraulic supports in real time.

[0003] However, the existing support force detection device for hydraulic supports has the following shortcomings: During use, the support force detection device can remove methane gas from the air entering the detection device through adsorption by adsorbent particles, but it does not have the function of automatic replacement of adsorbent particles. When the adsorbent particles reach a saturated state, the air entering the detection device will carry methane gas again. At this time, the methane gas carried in the air is easily ignited when arcs are generated when electrical components such as relays and contactors are turned on and off, posing a risk of explosion.

Then, the detection device is placed on the placement rack prepared around the hydraulic support, and two collection cylinders are also placed on the placement rack, and each collection cylinder is aligned with the bottom outlet of each rectangular tube 214; During the filling stage, when it is necessary to fill the adsorbent particles, the touch screen 116 and the control panel 114 are first used to start the two servo motors 221 at the same time. At this time, each servo motor 221 that is started will drive the corresponding second drive tooth 224 to rotate in cooperation with the connecting piece 222 and the corresponding connecting rod 223 connected thereto. Subsequently, the two rotating second drive teeth 224 will drive the corresponding circular ring block 211 to rotate in cooperation with the two first drive teeth 220 and the two limit rings 210. When the two circular ring blocks 211 complete the rotation operation, the interior of each first feed hole 216 is exactly connected to the interior of each second feed hole 217 (in the initial state, each first feed hole 216 is staggered with each second feed hole 217), and the interior of each first discharge hole 213 is exactly connected to the interior of each second discharge hole 215. The first and second discharge holes 213 and 215 are connected (in the initial state, each first discharge hole 213 is staggered with each second discharge hole 215), the interior of each group of air inlet holes 202 is just staggered (in the initial state, the interiors of each group of air inlet holes 202 are connected), and the interior of each group of air outlet holes 204 is just staggered (in the initial state, the interiors of each group of air outlet holes 204 are connected). When each first feed hole 216 is connected with the interior of each second feed hole 217, the adsorbent particles in the two spaces inside the storage box 201 will be transported to the space composed of the top of the corresponding partition plate 209, the corresponding groove of the double-slot column 226 and the corresponding plate bracket 207 under the cooperation of the corresponding feed pipe 205, the corresponding first feed hole 216 and the corresponding second feed hole 217. When the two spaces are filled, one of the circular ring blocks 211 is reset to its original position. During the detection phase, when it is necessary to detect the supporting force of the hydraulic support, the touch screen 116 and the control panel 114 are used to start the pressure sensor 109. The activated pressure sensor 109 will detect the oil pressure in the cylinder inside the hydraulic support column. The pressure sensor 109 will then transmit the pressure data detected each time to the control panel 114 in the form of an electrical signal. The control panel 114 will then calculate the pressure data received each time into the supporting force (supporting force = oil pressure × piston area (measured in advance)). The control panel 114 will then compare the supporting force data calculated each time with the control panel 114. The support force data threshold set in advance is compared. When all the calculated support force data are lower than the support force data threshold set in advance by the control panel 114, the control panel 114 will not send an alarm reminder to the alarm 103, and each calculated support force data will be stored. When one of the calculated support force data is higher than the support force data threshold set in advance by the control panel 114, the control panel 114 will send an alarm instruction to the alarm 103, and then the alarm 103 that receives the alarm instruction will send an alarm reminder to alert the staff, and will also store each calculated support force data. The data are stored. When it is necessary to transmit the data wirelessly to the monitoring equipment in the monitoring room, the control panel 114 is first connected to the monitoring equipment in the monitoring room by the antenna 118. Then, the touch screen 116 and the control panel 114 are used to transmit the data to the monitoring equipment in the monitoring room for the staff to watch. At the same time, when the control panel 114 starts the pressure sensor 109, the control panel 114 will also start the fan 115. At this time, the fan 115 will use a group of internally connected air inlet holes 202, a group of internally connected air outlet holes 204, the corresponding space, and the corresponding connection. The through-tube 218, the corresponding second circular mounting hole 119, the corresponding two porous sheets 212 and the corresponding second filter 120 cooperate to filter out dust from the low-temperature air in the coal mine before inhaling it. When the inhaled low-temperature air contacts the adsorbent particles inside the space, the adsorbent particles adsorb and remove the methane gas in the air. The treated low-temperature air then enters the interior of the box 101, removes the heat that is dispersed into the interior of the box 101 during operation, and is then transported to the interior of the first circular mounting hole 104. Afterwards, it passes through the mesh of the first filter 105 and is transported back to the coal mine. During the automatic replacement stage, when the adsorbent particles need to be replaced (the space corresponding to the circular block 211 that was previously reset to its original position), the other circular block 211 is reset first, allowing the adsorbent particles inside the corresponding space to work and continue to process the air entering the box body 101. At the same time, one of the circular blocks 211 is rotated again to the corresponding set of air inlet holes 202 and the corresponding set of air outlet holes 204. Then the control board 114 controls the drive motor 219 (corresponding to one of the circular blocks 211) to start. At this time, the started drive motor 219 will drive the corresponding partition plate 209 to rotate with the cooperation of the corresponding plate bracket 207 and the corresponding rotating rod 208. When the partition plate 209 completes 180 degrees, the partition plate 209 is used. The adsorbent particles will be guided to the corresponding collection cylinder through the corresponding first discharge hole 213, the corresponding second discharge hole 215 and the corresponding rectangular tube 214. When the partition plate 209 completes the rotation operation, the control board 114 will pause the corresponding drive motor 219. At this time, the new adsorbent particles transported out from the inside of the corresponding storage box 201 will fall into the corresponding space. When the adsorbent particles in the corresponding space of the other circular block 211 need to be replaced, one of the circular blocks 211 will be reset and the other circular block 211 will be rotated again to the corresponding set of air inlet holes 202 and the corresponding set of air outlet holes 204. This process can be repeated to automatically replace the adsorbent particles without stopping the fan 115.

[0025] Among them, the porous plug 225 is used for the wires connecting the two micro vibrators 203 and the antenna 118 to the electrical components inside the box 101 to pass through. The two micro vibrators 203 can allow the adsorbent particles inside the storage box 201 to be normally transported to the inside of the feed pipe 205 through vibration.

[0026] Among them, the sensor interface 102, the alarm 103, the pressure sensor 109, the power module 113, the control board 114 (PLC control board), the fan 115, the touch screen 116, the antenna 118, the micro vibrator 203, the drive motor 219 and the servo motor 221 are all existing technologies, and their models can be selected according to actual conditions. No further explanation is given here.
