Detailed Implementation

[0025] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0026] To accommodate the operation of two jaw crushers, the ore bin has a "Y"-shaped structure. A level gauge mounting hole is designed in the middle of the bin. The level gauge, used to measure the material level, transmits the data to the main control room via communication. To ensure the accuracy and lifespan of the level gauge, several issues arise: 1. The ore bin is 38 meters deep, and the level gauge is a radar level gauge with a flange mounting structure. The level gauge measures a sector area, therefore, the verticality of the installation must be ensured. 2. The level gauge is placed inside the ore bin, where it is exposed to water and moisture, affecting its lifespan. Therefore, waterproof and moisture-proof measures are necessary. 3. After placement inside the ore bin, the radar level gauge is affected by dust, requiring regular cleaning to ensure measurement accuracy. Therefore, to address these issues, this application provides an ore bin level measurement device.

[0027] Please see Figure 1 , Figure 2 and Figure 3 According to a first aspect of this application, a ore bin level measuring device is provided. The ore bin 200 is Y-shaped, and a level gauge mounting hole 210 is provided in the middle of the ore bin 200. The level measuring device includes an L-shaped mounting frame 110, a lifting device 120, and a level measuring component 130. The L-shaped mounting frame 110 is erected on the ground near the level gauge mounting hole 210. The L-shaped mounting frame 110 includes a horizontal bar 111 and a vertical bar 112 that are angled and connected. The vertical bar 112 is used to connect to the ground. The lifting device 120 includes a winch 121, a pulley 122, and a wire rope 123. The wire rope 123 is wound around the winch 121 and the pulley 122 in sequence. Wheel 122; The level measuring assembly 130 includes a radar level gauge 131 and a protective cover 132. The protective cover 132 is installed above the radar level gauge 131. The protective cover 132 includes a cylindrical sleeve 1321, a top plate 1322, and a first flange 1323. The top plate 1322 is fixedly connected to the top of the sleeve 1321, and the bottom of the sleeve 1321 is fixedly connected to the first flange 1323. The radar level gauge 131 is provided with a second flange 1311, and the first flange 1323 is connected to the second flange 1311. The top plate 1322 is connected to the wire rope 123, and the measuring end of the radar level gauge 131 is located outside the protective cover 132.

[0028] The lifting device 120 can send the material level measuring device into the ore bin 200 through the material level gauge mounting hole 210. The lifting device 120 can ensure that the radar material level gauge 131 is lowered vertically into the ore bin 200 under the action of the wire rope 123.

[0029] The protective cover 132 is installed above the radar level gauge 131 to protect the radar level gauge. The protective cover 132 is connected to the radar level gauge through the first flange 1323 and the second flange 1311 for easy installation and disassembly. The measuring end of the radar level gauge is located outside the protective cover 132, which facilitates the radar level gauge to measure the level of the ore bin 200.

[0030] Therefore, the radar level gauge 131 is covered by a protective cover 132 to prevent the damp or dusty environment inside the ore bin 200 from affecting the lifespan of the radar level gauge 131, thereby improving the accuracy of the radar level gauge 131. Since the radar level gauge 131 measures in a fan-shaped area, it can be sent into the ore bin 200 through the radar level gauge 131 mounting hole 210 by the lifting device 120. The measuring end of the radar level gauge 131 can measure the material level inside the ore bin 200.

[0031] like Figure 3 As shown, in some embodiments, the sleeve 1321 is a galvanized steel pipe, and the sleeve 1321 is welded to the top plate 1322; the galvanized steel pipe is welded to the top plate 1322, and the top plate 1322 can be made of iron plate. Welding the galvanized steel plate to the top plate 1322 can ensure the strength and sealing of the protective cover 132, so that the protective cover 132 has high strength and good sealing performance. In some embodiments, the galvanized steel pipe can be a galvanized steel pipe with a diameter of 159mm, and the top plate 1322 can be made of iron plate with a thickness of 5mm.

[0032] like Figure 2 and Figure 3 As shown, in some embodiments, a U-shaped lifting ring is provided above the top plate 1322. The U-shaped lifting ring is welded to the top plate 1322 and connected to the wire rope 123. The U-shaped lifting ring is inverted, and welding can firmly fix the U-shaped lifting ring to the top plate 1322, forming a high-strength connection. The inverted U-shaped lifting ring and the connection to the wire rope 123 allow the level measuring component 130 to be inserted into or removed from the level gauge mounting hole 210 under the action of the winch 121 and the wire rope 123.

[0033] like Figure 2 and Figure 3As shown, in some embodiments, the first flange 1323 has a first connecting hole, and the second flange 1311 has a second connecting hole. The first flange 1323 and the second flange 1311 are fixedly connected by fasteners. The fasteners include threaded parts and nuts. The threaded parts pass through the first connecting hole and the second connecting hole and are threadedly connected to the nuts. In some embodiments, there are four first connecting holes arranged along the circumference of the first flange 1323. Correspondingly, there are four second connecting holes arranged along the circumference of the second flange 1311. The positions of the second connecting holes and the first connecting holes correspond one-to-one. The threaded parts can be galvanized bolts. The threaded parts pass through the first connecting hole and the second connecting hole in sequence and are fixedly connected by nuts. The bolt and nut connection facilitates installation and disassembly.

[0034] like Figure 2 and Figure 3 As shown, in some embodiments, a sealing gasket is also provided between the first flange 1323 and the second flange 1311. The radar level gauge 131 is installed inside the protective cover 132, and the connection between the first flange 1323 and the second flange 1311 is provided to ensure the stability and sealing of the connection between the first flange 1323 of the protective cover 132 and the second flange 1311 of the radar level gauge 131. In some embodiments, the sealing gasket can be a rubber sealing gasket.

[0035] like Figure 2 and Figure 3 As shown, in some embodiments, the sleeve 1321 has a wire outlet hole on its side wall, and the sleeve 1321 also has an elbow 1324 on its side wall. The elbow 1324 is connected to the side wall of the sleeve 1321 and communicates with the wire outlet hole; the material level gauge wire passes through the elbow 1324 and exits the protective cover 132.

[0036] like Figure 2 and Figure 3 As shown, in some embodiments, the outlet of the elbow 1324 is further provided with a seal, and the outlet of the elbow 1324 can be sealed with a waterproof sealant, such as epoxy resin, to ensure overall sealing.

[0037] In some embodiments, the elbow 1324 is a galvanized elbow, and the elbow 1324 is welded to the side wall of the sleeve 1321. Welding the galvanized elbow to the side wall of the sleeve 1321 ensures the strength and sealing of the protective cover 132.

[0038] like Figure 1As shown, in some embodiments, the horizontal bar 111 and the vertical bar 112 are perpendicular to each other. One end of the horizontal bar 111 is connected to the vertical bar 112, and the other end of the horizontal bar 111 extends towards one side of the level gauge mounting hole 210, with the other end of the horizontal bar 111 positioned above the level gauge mounting hole 210. The pulley 122 is positioned above the level gauge mounting hole 210, and the winch 121 is positioned above the ground. This ensures that the level measuring assembly 130 can be vertically inserted into or removed from the level gauge mounting hole 210 under the action of the winch 121 and the wire rope 123.

[0039] like Figure 1 As shown, in some embodiments, the radar level gauge 131 and the steel wire rope 123 extending along the level gauge mounting hole 210 are coaxially arranged with the level gauge mounting hole 210. This ensures that the level measuring assembly 130 can be vertically inserted into or removed from the level gauge mounting hole 210 under the action of the winch 121 and the steel wire rope 123.

[0040] like Figure 1 As shown, in some embodiments, the height of the vertical rod 112 is 0.9m-1.2m; the height of the vertical rod 112 can be 0.9m, 1m, 1.1m or 1.2m, which makes it convenient for workers to start the winch 121 on the ground, so as to put the radar level gauge 131 into the mine 200 through the level gauge mounting hole 210 of the mine 200.

[0041] In some embodiments, the vertical rod 112 is connected to the ground by expansion bolts. The expansion bolt consists of a threaded rod, an expansion tube, and a tapered nut. It is securely fixed to the ground by drilling a hole in the ground, inserting the expansion bolt, and tightening the nut, causing the expansion tube to expand. This provides high fixing strength, adapts to different usage requirements, and is easy to install and highly removable.

[0042] In some embodiments, the winch 121 is either an electric winch 121 or a manual winch 121. The electric winch 121 is convenient to operate, while the manual winch 121 can be used when it is inconvenient to connect to a power source, providing a dual option. In some embodiments, the winch 121 is fixed to the crossbar 111, and the winch 121 can have a longitudinal tension of 150 kg, a drum diameter of 132 mm, and a drum inner diameter of 48 mm. The winch 121 can wind 12,330 meters of wire rope.

[0043] Therefore, this application involves vertically suspending a radar level gauge 131 within the level gauge mounting hole 210 of the ore bin 200, with a protective cover 132 encasing the radar level gauge 131. After installation, this has no impact on the crusher's material feeding, ensuring that the fan-shaped radar detection surface of the level gauge can penetrate the entire ore bin 200 without any deviation, effectively guaranteeing the accuracy of the level gauge measurement. Simultaneously, the protective cover 132 reduces the impact of water spray and humidity within the ore bin 200 on the radar level gauge 131, extending its service life. The radar level gauge 131 can be lowered and raised by winding a steel wire rope 123 around a winch 121, reducing the workload of maintenance personnel during level gauge cleaning.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature being directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
