Description

Technical Field

[0001] This application relates to the field of belt conveyor idler technology, and more specifically, to a belt conveyor idler frame for coal mines. Background Technology

[0002] During coal mining, the excavated coal needs to be transported to the outside via belt conveyors. The belt of the conveyor is supported by idlers, which are usually fixed by idler frames. The idlers are connected to the idler frames through bearings and other structures. During long-term rotation and rolling, the surface of the idlers and the bearings are prone to wear, which affects the rotation speed of the idlers and may even cause the belt to run unstably. In order to reduce wear, the idlers usually need to be lubricated with machine oil regularly. However, since the idler frames also need to support the belt, the belt and other related components need to be disassembled each time lubrication is performed. The operation is cumbersome and time-consuming, which reduces the efficiency of coal conveying and affects the overall production progress. Summary of the Invention

[0003] The purpose of this application is to provide a coal mine belt conveyor idler frame, which can solve the technical problem that existing coal mine belt conveyor idlers require disassembly of the belt and other related components each time they are lubricated, which is cumbersome and time-consuming, reduces the efficiency of coal mine conveying, and affects the overall production progress.

[0004] This application provides a coal mine belt conveyor idler frame, including a support frame, idlers, and an oiling assembly. The idlers are rotatably mounted on the support frame via bearings. The oiling assembly includes a storage plate, an oil tank, an oil pusher plate, a transmission assembly, a connector, and a first oiling pipe. The storage plate is fixedly mounted on the support frame, and the oil tank can be placed on the storage plate. The top of the oil tank has a first through hole, and the bottom of the oil tank has a second through hole. The oil pusher plate is slidably mounted inside the oil tank. The transmission assembly is used to drive the oil pusher plate to move downward. The connector can be threadedly connected to the first through hole or the second through hole, and the first oiling pipe is connected to the connector.

[0005] The oiling assembly further includes a second oiling pipe and a nozzle. One end of the second oiling pipe is connected to the first oiling pipe, and the nozzle is connected to the other end of the second oiling pipe.

[0006] The transmission assembly includes a push rod, which can be threadedly connected to the first through hole or the second through hole, and the push rod can abut against the push plate.

[0007] The push rod is arc-shaped at one end near the oil-pushing plate, and arc-shaped grooves are provided at the top and bottom of the oil-pushing plate, allowing the push rod to abut against the arc-shaped grooves.

[0008] The push rod has a handle at the end away from the oil-pushing plate.

[0009] The oil storage tank is fixedly equipped with a guide rod, and the oil pusher plate is slidably sleeved on the guide rod.

[0010] The first oiling pipe has a corrugated hose at one end near the joint.

[0011] The shelf has a through slot, and the connector can pass through the through slot and be threadedly connected to the first through hole or the second through hole.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a coal mine belt conveyor idler frame. During use, a transmission assembly drives an oil-pushing plate downwards, pressing down and squeezing out the oil stored in the oil tank through a second through-hole. The oil is then transported via a first oiling pipe to the bearing of the idler for lubrication. When the oil in the tank is depleted, the oil-pushing plate is positioned at the bottom of the tank. Oil is then injected into the tank through the first through-hole. The first oiling pipe and connector are then disassembled and reconnected to the first through-hole. The tank is then flipped over, placing the oil-pushing plate at the top of the tank. The transmission assembly then drives the oil-pushing plate downwards to continue lubrication. This idler frame, with its oiling assembly, is simple and quick to operate, completing lubrication without disassembling the belt or other related components, thus improving the continuity and efficiency of coal mine production. Furthermore, the idler frame can quickly replenish the oil in the tank, enhancing ease of use. Attached Figure Description

[0030] like Figures 1 to 3 As shown in the figure, this application provides a coal mine belt conveyor idler frame, including a support frame 1, an idler 2, and an oiling assembly 3. The idler 2 is rotatably mounted on the support frame 1 via bearings. The oiling assembly 3 includes a storage plate 31, an oil tank 32, an oil pusher plate 33, a transmission assembly 4, a connector 34, and a first oiling pipe 35. The storage plate 31 is fixedly mounted on the support frame 1. The oil tank 32 can be placed on the storage plate 31. The top of the oil tank 32 is provided with a first through hole 36, and the bottom of the oil tank 32 is provided with a second through hole 37. The oil pusher plate 33 is slidably mounted inside the oil tank 32. The transmission assembly 4 is used to drive the oil pusher plate 33 to move downward. The connector 34 can be threadedly connected to the first through hole 36 or the second through hole 37. The first oiling pipe 35 is connected to the connector 34.

[0031] In use, the transmission assembly 4 drives the oil pusher plate 33 to move downwards. The oil pusher plate 33 presses down and squeezes the oil stored in the oil tank 32 out through the second through hole 37. Then, the oil is transported to the bearing part of the idler roller 2 through the first oiling pipe 35 for oiling and lubrication. When the oil in the oil tank 32 is used up, the oil pusher plate 33 is located at the bottom of the inside of the oil tank 32. Then, oil is injected into the oil tank 32 through the first through hole 36. Then, the first oiling pipe 35 and the connector 34 are disassembled. Then, the first oiling pipe 35 and the connector 34 are connected to the first through hole 36. Then, the oil tank 32 is flipped over. After flipping, the oil pusher plate 33 is located at the top of the inside of the oil tank 32. Then, the transmission assembly 4 drives the oil pusher plate 33 to move downwards to continue the oiling and lubrication operation.

[0032] The idler roller 2 frame is equipped with an oiling component 3, which makes operation simple and quick. Lubrication can be completed without disassembling the belt and other related parts, improving the continuity and efficiency of coal mine production. Moreover, the idler roller 2 frame can quickly replenish the oil storage tank 32, improving ease of use.

[0033] like Figure 1 and 4 As shown, in this embodiment, the oiling assembly 3 further includes a second oiling pipe 38 and a nozzle 39. One end of the second oiling pipe 38 is connected to the first oiling pipe 35, and the nozzle 39 is connected to the other end of the second oiling pipe 38.

[0034] During use, the oil is delivered from the first oiling pipe 35 to the second oiling pipe 38, and then from the second oiling pipe 38 to the nozzle 39 for spraying out to lubricate the bearing parts of the idler roller 2. By setting the nozzle 39, the bearing parts of the idler roller 2 can be precisely lubricated.

[0035] like Figures 1 to 3 As shown, in this embodiment, the transmission component 4 includes a push rod 41, which can be threadedly connected to the first through hole 36 or the second through hole 37, and the push rod 41 can abut against the push plate 33.

[0036] When in use, insert the push rod 41 into the first through hole 36 or the second through hole 37 and abut it against the oil pusher plate 33. Then rotate the push rod 41, and the push rod 41 will push the oil pusher plate 33 to move downward.

[0037] like Figures 1 to 3 As shown, in this embodiment, the end of the push rod 41 near the oil-pushing plate 33 is arc-shaped, and arc-shaped grooves 310 are provided on the top and bottom of the oil-pushing plate 33, and the push rod 41 can abut against the arc-shaped grooves 310.

[0038] The arc-shaped end of the push rod 41 abuts against the arc-shaped groove 310, which can reduce the frictional resistance between the push rod 41 and the push plate 33.

[0039] like Figures 1 to 3 As shown, in this embodiment, a handle 42 is provided at the end of the push rod 41 away from the push plate 33; the handle 42 makes it easier for the operator to apply force to turn the handle 42, thus improving the ease of use.

[0040] like Figures 1 to 3 As shown, in this embodiment, a guide rod 311 is fixedly installed inside the oil tank 32, and the oil pusher plate 33 is slidably sleeved on the guide rod 311; the cooperation between the oil pusher plate 33 and the guide rod 311 plays a guiding and limiting role for the oil pusher plate 33.

[0041] like Figures 1 to 3 As shown, in this embodiment, a corrugated hose 312 is provided at one end of the first oiling pipe 35 near the connector 34; the corrugated hose 312 is telescopic and bendable, allowing the connector 34 to move within a certain range, which facilitates the connection of the connector 34 with the first through hole 36 or the second through hole 37.

[0042] like Figures 1 to 3As shown, in this embodiment, the shelf 31 has a through groove 313, and the connector 34 can pass through the through groove 313 and be threaded to the first through hole 36 or the second through hole 37, which facilitates the connection between the connector 34 and the first through hole 36 or the second through hole 37 and improves the ease of use.

[0043] Working principle: When the coal mine belt conveyor idler frame provided in this application is in use, the push rod 41 is threaded into the first through hole 36 and abuts against the oil pusher plate 33. Then, the handle 42 is turned to drive the push rod 41 to rotate. The push rod 41 pushes the oil pusher plate 33 to move downward. The oil pusher plate 33 presses down and squeezes the oil stored in the oil tank 32 out through the second through hole 37. Then, the oil is transported to the second oiling pipe 38 through the first oiling pipe 35, and then to the nozzle 39 through the second oiling pipe 38 to spray out, so as to perform oiling and lubrication on the bearing part of the idler roller 2.

[0044] When the oil in the oil tank 32 is used up, the oil pusher plate 33 is located at the bottom of the inside of the oil tank 32. Then, rotate and remove the pusher rod 41, and then inject oil into the oil tank 32 through the first through hole 36. Then, disassemble the first oiling pipe 35 and the connector 34, and then connect the first oiling pipe 35 and the connector 34 to the first through hole 36. Then, flip the oil tank 32 over. After flipping, the oil pusher plate 33 is located at the top of the inside of the oil tank 32. Then, thread the pusher rod 41 into the second through hole 37 and abut against the oil pusher plate 33. Then, turn the handle 42 to drive the pusher rod 41 to rotate. The pusher rod 41 pushes the oil pusher plate 33 downward to continue the oiling and lubrication operation.

[0045] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
