Description

Technical Field

[0001] This invention relates to the field of mineral extraction technology, specifically to a large-diameter manhole cover for open-pit mines. Background Technology

[0002] Manhole covers are constantly being passed by vehicles and pedestrians. They are round because every diameter of a round manhole cover is the same length through its center. This way, if a vehicle runs over the manhole cover, its diameter will always be slightly wider than the opening below, preventing the cover from falling into the manhole. Mining manhole covers are similar, preventing people from falling in and also making them easy to open and close, playing an important role in mining operations.

[0003] Many existing manhole covers are square. If the fixing parts become loose during use, there is a risk of vehicles or pedestrians falling through. In addition, traditional manhole covers have poor corrosion resistance and may be corroded more severely when used in mines.

[0004] Existing manhole covers need to be installed into matching holes, which requires the production of many manhole covers of different sizes. This results in high production costs and risks, and is also quite wasteful of resources. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-6 The present invention provides a technical solution: a large-diameter manhole cover for an open-pit mine, comprising a main body 1, an auxiliary body 2, and an adjustment and fixing body 3. The auxiliary body 2 is located inside the main body 1, and the adjustment and fixing body 3 is located inside the main body 1. The main body 1 includes a manhole cover fixing base 101, a sealing manhole cover 102, a sealing protective pad 103, and an auxiliary handle 104. The sealing manhole cover 102 is movably installed at the inner end of the mounting groove 109, the sealing protective pad 103 is fixedly installed at the lower end of the sealing manhole cover 102, and the auxiliary handle 104 is fixedly installed at the upper end of the sealing manhole cover 102.

[0032] The main structure 1 also includes a movable plate 105, an adapter hole 106, a movable bolt 107, a movable groove 108, an installation groove 109, a flow pipe 1010, and a drain hole 1011. The movable plate 105 is fixedly installed on the left end of the sealed manhole cover 102. The adapter hole 106 is fixedly installed on the inner end of the movable plate 105. The movable bolt 107 is fixedly installed on the inner end of the adapter hole 106. The movable groove 108 is fixedly installed on the upper end of the inner end of the manhole cover fixing base 101. The installation groove 109 is fixedly installed on the upper end of the inner end of the manhole cover fixing base 101. The flow pipe 1010 is fixedly installed on the lower end of the manhole cover fixing base 101. The drain hole 1011 is fixedly installed on the inner end of the sealed manhole cover 102.

[0033] Auxiliary mechanism 2 includes a fixing steel spike 1 201, an anti-corrosion plate 1 202, an anti-corrosion plate 2 203, a fixing steel spike 2 204, a sealing plate 205, an anti-corrosion plate 3 206, a slot 1 207, a slot 2 208, and a sealing cover plate 209. The fixing steel spike 1 201 is fixedly installed at the lower end of the manhole cover fixing base 101. The anti-corrosion plate 1 202 is fixedly installed at the outer end of the flow pipe 1010. The anti-corrosion plate 2 203 is fixedly installed at the inner end of the flow pipe 1010. The fixing steel spike 2 204 is fixedly installed at the left end of the fixing arc-shaped plate 306. The sealing plate 205 is fixedly installed at the lower end of the sealing manhole cover 102. The anti-corrosion plate 3 206 is fixedly installed at the lower end of the sealing plate 205. The slot 1 207 is fixedly located at the left and right ends of the inner end of the manhole cover fixing base 101. The slot 2 208... 08 is fixedly installed at the upper end of the slot 1 207, and the sealing cover 209 is movably installed at the inner end of the slot 1 207. Before installing the manhole cover, the auxiliary handle 104 needs to be hooked with a tool and then pulled up. The sealing cover 102 will rotate in the movable groove 108 through the movable bolt 107, and the sealing cover 102 can be pulled up. When used in the mine, the environment is highly corrosive. The anti-corrosion plate 206 can prevent substances in the water from corroding the lower end of the sealing cover 102. After the manhole cover is installed, the fixing steel spike 201 can make the manhole cover more firmly fixed to the ground. When the manhole cover needs to be dug out, the soil around the manhole cover is dug out, and then the sealing cover 209 is opened. The hook is hooked on the slot 2 208 and pulled up to lift the manhole cover. This way, the manhole cover can be removed, which is convenient for maintenance and replacement.

[0034] The adjusting and fixing mechanism 3 includes a threaded hole 301, a sealing gasket 302, a threaded rod 303, a fixing nut 304, a sealing bearing 305, a fixing arc-shaped plate 306, a movable hole 307, a limiting rod 308, an auxiliary plate 309, a fixing steel spike 310, a corrosion-resistant spring 311, and a fixing plate 312. Taking the left adjusting and fixing mechanism as an example, the threaded hole 301 is fixedly installed at both ends of the inner end of the flow pipe 1010, the sealing gasket 302 is fixedly installed at the inner end of the threaded hole 301, and the threaded rod 303 is movably installed at the inner end of the threaded hole 301. The fixing nut 304 is fixedly installed on the right end of the threaded rod 303, the sealing bearing 305 is fixedly installed on the left end of the threaded rod 303, the fixing arc plate 306 is fixedly installed on the left end of the sealing bearing 305, the movable hole 307 is fixedly set at the left and right ends of the inner end of the flow pipe 1010, the limiting rod 308 is movably installed in the inner end of the movable hole 307, the auxiliary plate 309 is fixedly installed on the right end of the limiting rod 308, the fixing steel spike 310 is fixedly installed on the left end of the limiting rod 308, and the corrosion-resistant spring 311 is fixedly installed on the left end of the fixing arc plate 306. The fixing plate 312 is fixedly installed on the left end of the outer end of the limiting rod 308. The fixing plate 312 is fixedly connected to the corrosion-resistant spring 311. Tightening the fixing nut 304 will cause the threaded rod 303 to rotate in the threaded hole 301, which will cause the fixing arc plate 306 to be pressed to both sides to complete the fixation. During this process, the auxiliary plate 309 is struck with a hammering tool, and the limiting rod 308 will be inserted into the ground through the fixing steel spike 310 for auxiliary fixation, and at the same time, it can prevent the fixing arc plate 306 from moving. If the manhole cover is misaligned during the process, causing instability in the fixation, the corrosion-resistant spring 311 will drive the limiting rod 308 to be inserted into the ground through the fixing plate 312. The corrosion-resistant spring 311 can also provide elasticity to make the insertion more secure. Conversely, when it is necessary to remove the manhole cover, only the opposite operation needs to be performed. Tightening the fixing nut 304 in the opposite direction will drive the threaded rod 303 to rotate in the threaded hole 301, and then drive the fixing arc plate 306 to move. When the fixing arc plate 306 is disengaged from the ground, the tightening is completed, and the manhole cover can be easily removed.

[0035] Working principle: When there is water on the ground, it flows into the flow pipe 1010 through the leakage hole 1011 inside the sealed manhole cover 102 and then is discharged. The flow pipe 1010 is inserted into the hole where the manhole cover needs to be installed. Then, the fixing nut 304 is turned, which drives the threaded rod 303 to rotate within the threaded hole 301. This causes the fixing arc-shaped plate 306 to be pressed to both sides, completing the fixation. During this process, the auxiliary plate 309 is struck with a hammering tool, causing the limiting rod 308 to be inserted into the ground through the fixing steel spike 310 for auxiliary fixation. This also prevents the fixing arc-shaped plate 306 from shifting during movement, thus ensuring stability. The corrosion-resistant spring 311, through the fixing plate 312, drives the limiting rod 308 to be inserted into the ground. The corrosion-resistant spring 311 also provides elasticity to make the insertion more secure. Conversely, when the manhole cover needs to be removed, the opposite operation is performed: turning the fixing nut 304 in the opposite direction will drive the threaded rod 308 to rotate. 03. Rotate within the threaded hole 301, then move the fixed arc plate 306. When the fixed arc plate 306 disengages from the soil, the twisting is complete, and the manhole cover can be easily removed. Before installing the manhole cover, hook the auxiliary handle 104 with a tool and pull it up easily. The sealed manhole cover 102 will rotate within the movable groove 108 via the movable bolt 107, allowing the sealed manhole cover 102 to be pulled up. Then, operate inside the device. In mines, the environment is highly corrosive. The anti-corrosion plate 206 can prevent substances in the water from eroding the lower end of the sealed manhole cover 102. After the manhole cover is installed, the fixing steel spike 201 can make the manhole cover more firmly fixed to the ground. When the manhole cover needs to be dug out, dig out the soil around the manhole cover, then open the sealing cover plate 209, hook the hook into the slot 208, and pull up to lift the manhole cover. This way, the manhole cover can be pulled out of the soil, and then the manhole cover can be replaced or the internal parts of the device can be repaired, effectively reducing the cost of using the manhole cover.

[0036] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
