Description

Technical Field

[0001] This utility model relates to the field of lubrication device technology, and in particular to an automatic lubrication replenishment device for the sheave of a coal mine electromechanical hoist. Background Technology

[0002] The head sheave is a fixed pulley at the top of the mine shaft headframe that adjusts the direction of the wire rope. Its function is to support the wire rope connecting the hoist drum and the hoisting container and guide the wire rope to change direction. During use, the head sheave requires a lubrication device to lubricate the bearing housing of the sheave axle.

[0003] In the prior art, patent CN218295282U discloses an automatic oil supply device for lubricating the top sheave of a hoist, comprising a top sheave body, a fixed frame, a fixed pipe, a pump body, and an extrusion component. Rotating shafts are fixedly connected to both ends of the top sheave body. Bearing seats are fixedly connected inside the fixed frame and are fixedly connected to the rotating shafts. The fixed pipe is fixedly connected inside the fixed frame and has multiple sets of pipes fixedly connected to it. A nozzle is fixedly connected to one end of each pipe. This device enables the pump body and piston plate to work together to spray lubricating oil from the fixed pipe in a cross-flow manner, thus lubricating the bearing seats and rotating shafts. It is easy to operate, requires no hoist shutdown, reduces the workload of workers, and avoids dangerous situations.

[0004] The aforementioned patented technology requires a pump to draw lubricating oil from the tank into the nozzle during lubrication. However, if the pump malfunctions, lubrication is impossible, and the lubricating oil cannot be fully recovered, leading to oil contamination of the equipment and waste. Therefore, this application proposes an automatic lubrication replenishment device for the sheave of a coal mine electromechanical hoist. Utility Model Content

[0040] Reference Figures 1 to 5 An automatic lubrication replenishment device for the sheave lubrication of a coal mine electromechanical hoist, comprising:

[0041] The main body of the sheave 100, and the transverse shaft 200 located at the transverse axis center of the main body of the sheave 100;

[0042] Support plate 300, there are two support plates 300, which are used to support both ends of the horizontal shaft 200, and support legs 400 are fixedly provided on the lower surface of the support plate 300.

[0043] The lubrication supply assembly 600 includes a lower housing 601 fixed to the upper surface of the support plate 300 and a detachable upper housing 602 disposed on the top of the lower housing 601. A pressure box 603 and an oil reservoir 604 are fixed to the lower surface of the support plate 300, and a filter screen 605 is fixed to the inner wall of the oil reservoir 604.

[0044] In this invention, by setting up an oil return pipe 607, the lubricating oil dripping from the bearing housing 500 can flow back to the interior of the oil storage tank 604 through the oil return pipe 607, realizing the reuse of lubricating oil. At the same time, under the action of the filter screen 605, the lubricating oil entering the oil outlet pipe 606 can be filtered to prevent impurities from clogging the oil injector 6011.

[0048] By setting a bevel gear 6014, the rotation of the horizontal shaft 200 can drive the rotating rod 6013 to rotate.

[0049] Reference Figure 4 In a preferred embodiment, a rectangular plate 6015 and a sealing piston plate 6016 are slidably disposed on the inner wall of the pressure box 603, a reciprocating screw 6017 is fixedly disposed at the bottom end of the rotating rod 6013, and a threaded hole is provided on the upper surface of the rectangular plate 6015 for threaded connection with the outer surface of the reciprocating screw 6017.

[0050] By setting a reciprocating screw 6017, the rectangular plate 6015 can be driven to move up and down reciprocally during the rotation of the reciprocating screw 6017.

[0051] Reference Figure 4 In a preferred embodiment, two symmetrical push rods 6018 are fixedly provided on the lower surface of the rectangular plate 6015, and the bottom ends of the two push rods 6018 are fixedly connected to the lower surface of the sealing piston plate 6016.

[0052] By setting the push rod 6018, the sealing piston plate 6016 can be driven to move up and down reciprocally during the movement of the rectangular plate 6015.

[0053] Reference Figure 5 In a preferred embodiment, the inner bottom wall of the pressure chamber 603 is provided with an air intake pipe 6019 extending to the lower surface of the pressure chamber 603, and the surface of the air intake pipe 6019 is provided with an air intake one-way valve 6020, and the bottom end of the air intake pipe 6019 is provided with a filter cover.

[0054] By setting up the suction pipe 6019, it is convenient to draw outside air into the pressurization box 603 when the sealing piston plate 6016 moves upward, in preparation for the next pressurization.

[0055] Reference Figure 5 In a preferred embodiment, the inner bottom wall of the pressurization box 603 is fixedly provided with a pressurization pipe 6021 extending to the bottom of the oil storage tank 604, and the surface of the pressurization pipe 6021 is provided with a one-way valve 6022 for venting. The front of the oil storage tank 604 is provided with an oil filling port, and the inner wall of the oil filling port is provided with a sealing plug.

[0056] By setting up a pressurization pipe 6021, when the sealing piston plate 6016 moves downward, the air in the pressurization box 603 can be forced into the oil reservoir 604, thereby pressurizing the inside of the oil reservoir 604.

[0057] In this invention, by setting up a lubrication supply component 600, the device can continuously pressurize the inside of the oil storage tank 604 by the sealing piston plate 6016 during the rotation of the horizontal shaft 200. This causes the lubricating oil inside the oil storage tank 604 to be discharged into the arc-shaped pipe 6010 through the oil outlet pipe 606, and then sprayed onto the surface of the bearing seat 500 through the oil spray nozzle 6011, thus achieving automatic lubrication of the bearing seat 500 during the rotation of the sheave body 100.

[0058] Working principle: In actual use, during the rotation of the horizontal shaft 200, the rotating rod 6013 is driven to rotate by the two bevel gears 6014. The rotation of the rotating rod 6013 drives the reciprocating screw 6017 to rotate. The rotation of the reciprocating screw 6017 drives the rectangular plate 6015 to move downwards and reciprocally. This, in turn, drives the sealing piston plate 6016 to move up and down and reciprocally through the push rod 6018. As a result, the sealing piston plate 6016 continuously pressurizes the inside of the oil tank 604, causing the lubricating oil inside the oil tank 604 to be discharged into the arc-shaped pipe 6010 through the oil outlet pipe 606. The oil is then sprayed onto the surface of the bearing seat 500 through the oil nozzle 6011, achieving automatic lubrication of the bearing seat 500 during the rotation of the sheave body 100.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
