Description

Technical Field

[0001] This utility model relates to the field of mine safety equipment technology, specifically to a mine intelligent ventilation linkage early warning device. Background Technology

[0002] The intelligent ventilation linkage system for mines is a mine ventilation management solution based on modern information technology and automated control technology. It aims to improve mine ventilation efficiency, ensure miner safety, reduce energy consumption, and achieve intelligent management. It can monitor parameters such as methane, CO2, temperature, humidity, and wind speed in the mine in real time, thereby ensuring that the overall indicators are within a safe range.

[0003] In existing technologies, it is usually necessary to fix the corresponding detection elements and signal transmission equipment to the bracket. The bracket is usually fixed to the corresponding position in the wall or tunnel by positioning bolts, so as to determine the relevant parameters at the corresponding position.

[0004] The existing technology, which uses a bracket for fixing, can only detect relevant parameters within a certain range. When the range is exceeded, it is necessary to install another detection device or remove the existing detection device and reinstall it, which seriously reduces the work efficiency of operators and is not conducive to long-term detection.

[0048] Reference Figure 2 and Figure 3The bottom wall of the lifting rod 22 is provided with a positioning component 26, which includes a support cylinder 261, a drive cylinder 262, and an abutment block 263. In this embodiment, the support cylinder 261 is preferably a hollow circular barrel with an open top. The support cylinder 261 is vertically arranged and fixedly connected to the bottom wall of the lifting rod 22 by screws. The side wall of the support cylinder 261 is provided with a horizontal insertion hole 264. Here, each group of positioning slots 25 corresponds to one insertion hole 264, and the axial direction of the insertion hole 264 is parallel to the opening direction of the corresponding positioning slot 25. The drive cylinder 262 is located in the inner cavity of the support cylinder 261. In this embodiment, the abutment block 263 is preferably a conical block with its large end facing upward. The abutment block 263 is coaxially fixedly connected to the output end of the drive cylinder 262 by screws.

[0049] Reference Figure 2 and Figure 3 The support cylinder 261 has a guide groove on the bottom wall of each insertion hole 264. The inner cavity of the guide groove is provided with a guide block 265 and a first spring 266. The guide block 265 can slide along the long side of the guide groove. The two ends of the first spring 266 are fixedly connected to the support cylinder 261 and the guide block 265 respectively.

[0050] Reference Figure 2 and Figure 3 Each insertion hole 264 has an inner cavity equipped with an insertion rod 267. The insertion rod 267 passes through the inner cavity of the insertion hole 264 and can slide along the axial direction of the insertion hole 264.

[0051] Reference Figure 1 The top of the lifting rod is provided with a support plate 27. In this embodiment, the support plate 27 is preferably a circular plate. The support plate 27 is fixedly connected to the top of the lifting rod by means of screws.

[0052] Reference Figure 1 and Figure 4 The top wall of the support plate 27 is provided with multiple mounting devices 3, which are evenly distributed circumferentially along the vertical direction. Each mounting device 3 includes a mounting plate 31. In this embodiment, the mounting plate 31 is fixed to the top wall of the support plate 27 by screws.

[0053] Reference Figure 1 and Figure 4The top wall of the mounting plate 31 is evenly distributed with multiple locking components 32 along the vertical direction. Each locking component 32 includes a fixing block 321, a second spring 322, and a locking block 323. The fixing block 321 is fixed to the edge of the mounting plate 31 by screws. The extension and retraction direction of the second spring 322 is radial to the mounting plate 31. The second spring 322 is installed on the end face of the fixing block 321 near the axis of the mounting plate 31. The two ends of the second spring 322 are fixedly connected to the fixing block 321 and the locking block 323, respectively. The locking block 323 can abut against the side wall of the corresponding detection element to limit the corresponding detection element.

[0054] The implementation principle of the intelligent ventilation linkage early warning device in the mine is as follows: the operator fixes an appropriate number of counterweights 14 to the corresponding positions of the mounting base 11. Then, the operator first controls the angle between the mounting frame 121 and the mounting base 11 and the operation of the traveling wheel 122, thereby controlling the displacement of the mounting base 11.

[0055] When the support plate 27 needs to be raised to the corresponding height, the first motor 241 drives the first bevel gear 242 to rotate. The first bevel gear 242 meshes with the second bevel gear 243, driving the first gear 245 to rotate, which in turn drives the rack 246 to slide in the vertical direction, and then drives the lifting rod 22 to slide in the vertical direction. When it slides to a certain position, the drive cylinder 262 drives the abutment block 263 to slide in the vertical direction, thereby pushing the insertion rod 267 out of the insertion slot and inserting the end of the insertion rod 267 into the positioning slot 25, thus fixing the position of the lifting rod 22.

[0056] When it is necessary to release the limit on the lifting rod 22, the drive cylinder 262 drives the abutment block 263 upward. At this time, under the action of the first spring 266, the plug rod 267 is retracted and leaves the positioning groove 25.

[0057] Operators can install different types of detection elements on the mounting plate 31 and position the corresponding detection elements using the second spring 322 and the locking block 323.
