Since the drive wheel is used to control the movement of the wire rope during operation, it is subjected to a large force. When the drive wheel fails, it is inconvenient for the staff to disassemble it, and it is also inconvenient to repair or replace it later. In addition, the drive wheel needs to be lubricated during use to reduce friction, but the staff finds it inconvenient to operate during lubrication.

Currently, tower-type pumping units move steel wire ropes by driving a drive wheel. The drive wheel is installed and positioned through a bearing seat during use. Since the drive wheel is used to control the movement of the steel wire rope during operation, it is subjected to a large force. When the drive wheel fails, it is inconvenient for operators to disassemble the drive wheel, and it is also inconvenient to repair or replace the drive wheel afterward. In addition, the drive wheel needs to be lubricated during use to reduce friction, but the operation is inconvenient for operators during lubrication.

[0008] Also includes:

[0009] The drive motor has a drive wheel on one side, and a rotating shaft is fixedly installed at both ends of the drive wheel. One side of the rotating shaft is fixedly connected to a coupling, and a support assembly is provided on the outside of both rotating shafts.

[0010] The support assembly includes support frames symmetrically arranged on both sides of the drive wheel, a positioning frame is provided above the support frame, and bearing grooves are provided on the top of the support frame and the bottom of the positioning frame, and support blocks are symmetrically installed on the outer sides of the positioning frame.

[0011] The support frame has symmetrically installed positioning blocks on both sides above it, and a positioning rod is fixedly installed at the bottom of the support block. The top of the positioning block has a through-hole connecting groove, and the positioning rod is adapted to connect with the connecting groove.

[0012] Preferably, the positioning block is internally detachably connected with a positioning pin, and a positioning hole is provided through one side of the positioning rod, and the positioning pin is adapted to the positioning hole.

[0013] Preferably, the positioning pin has an installation groove on one side inside, and a screw is threadedly connected to the inside of the positioning pin on one side of the installation groove. One end of the screw is rotatably connected to a movable plate, and the movable plate is slidably connected to the installation groove.

A telescopic spring is sleeved on the lower outside of the movable rod, and one end of the telescopic spring is fixedly connected to the fixed frame. A fixing block is fixedly installed on the other end of the telescopic spring, and the fixing block is fixedly connected to the movable rod.

[0018] Compared with the prior art, the beneficial effects of this utility model are: This tower-type pumping unit drive device, which operates smoothly, has support components on both sides of the drive wheel, providing stable support for the drive wheel and facilitating maintenance and replacement of the drive wheel. It also facilitates sufficient lubrication of the bearings on the rotating shaft, improving convenience and practicality. The specific details are as follows:

[0019] 1. The drive motor drives the reducer, which in turn rotates the rotating shaft and drive wheel. When disassembling the rotating shaft, the rotating screw moves the movable plate in the mounting slot, causing the connecting rod to rotate. After the connecting rod rotates, it pulls the two limit rods closer together. During this movement, the limit rods cause the mounting block to slide on the support rod, allowing the limit rods to retract into the mounting slot. Then, the positioning pin can be removed, causing the positioning rod to lose its limit position. The positioning bracket can then be removed, causing the rotating shaft to lose its limit position, and the drive wheel can be removed. When installing the drive wheel and the rotating shaft, place the bearing on the outside of the rotating shaft into the bearing groove. Then, place the positioning frame on top of the bearing, so that the positioning rod passes through the connecting groove and the positioning pin passes through the positioning hole to position the positioning frame. Then, rotate the screw in the opposite direction to move the two limit rods away from each other, so that the limit rods extend out of the mounting groove to prevent the positioning pin from falling off. After the positioning frame is positioned, the positioning pin and the positioning hole are in close contact, which can ensure the reliability of the positioning frame. The support component can provide stable support for the drive wheel and facilitate the disassembly and maintenance of the drive wheel.

[0020] 2. When lubricating the bearings on the outside of the rotating shaft, push the movable rod upward to compress the telescopic spring, causing the limiting plate to move away from the cover plate. Then, rotate the limiting plate to offset it from the cover plate, allowing the cover plate to be opened and lubricating oil to be added to the adding tube. The lubricating oil enters the bearing groove on the positioning frame through the adding tube, and then, under the action of gravity, it can fully lubricate the inside of the bearing. After lubrication, close the cover plate and seal the adding tube with a sealing plug to prevent impurities from entering. Then, move the movable rod upward and rotate the limiting plate to make it rotate and intersect with the cover plate. Then, release the movable rod, and under the action of the telescopic spring, the limiting plate and the cover plate will abut against each other, thus positioning the cover plate. This facilitates the lubrication of the rotating shaft by the operator, allowing direct lubrication of the bearing's interior, ensuring the stability of the drive wheel's rotation, and improving practicality.

The positioning rods 206 are adapted to connect with the connecting grooves 207. The support assembly 2 can stably support the drive wheel 104 and facilitate the disassembly and maintenance of the drive wheel 104.

[0029] The positioning block 205 has a detachable positioning pin 208 inside, and a positioning hole 209 is provided through one side of the positioning rod 206. The positioning pin 208 is adapted to the positioning hole 209 to position the positioning frame 202. The positioning pin 208 has a mounting groove 210 inside one side, and a screw 211 is threadedly connected to the side of the mounting groove 210 inside the positioning pin 208. One end of the screw 211 is rotatably connected to a movable plate 212, and the movable plate 212 is slidably connected to the mounting groove 210 to facilitate the movement of the movable plate 212. Connecting rods 214 are symmetrically hinged to one side of the movable plate 212, and each end of the two connecting rods 214 away from the movable plate 212 is hinged to a limit rod 213. The limit rod 213 is slidably connected to the positioning pin 208, so that the movement of the movable plate 212 can drive the movement of the limit rod 213. Mounting blocks 215 are fixedly installed on one side of each of the two limit rods 213. A support rod 216 is slidably connected inside 215, and the support rod 216 is fixedly connected to the mounting groove 210 to support the movement of the limiting rod 213.

A sealing plug is fixedly installed at the bottom of the cover plate 218. A fixing frame 219 is fixedly installed on the upper side of the other side of the adding tube 217 to facilitate lubrication of the bearings outside the rotating shaft 105. A movable rod 220 is slidably connected inside the fixing frame 219, and a limiting plate 223 is rotatably connected to the top of the movable rod 220. A telescopic spring 221 is sleeved on the lower side of the movable rod 220. One end of the telescopic spring 221 is fixedly connected to the fixing frame 219, and a fixing block 222 is fixedly installed on the other end of the telescopic spring 221. The fixing block 222 is fixedly connected to the movable rod 220 to position the cover plate 218.

[0030] Working principle: Before using this type of tower-type pumping unit drive unit that operates smoothly, it is necessary to check the overall condition of the unit to ensure it can function normally. Figure 1 - Figure 5As shown, the operation of the drive motor 1 drives the reducer 102 to move, which in turn drives the rotating shaft 105 and the drive wheel 104 to rotate. When disassembling the rotating shaft 105, the rotating screw 211 drives the movable plate 212 to move in the mounting groove 210, which in turn drives the connecting rod 214 to rotate. After the connecting rod 214 rotates, it can pull the two limit rods 213 closer together. During the movement, the limit rods 213 drive the mounting block 215 to slide on the support rod 216, which allows the limit rods 213 to retract into the mounting groove 210. Then, the positioning pin 208 can be removed, so that the positioning rod 206 loses its limit. The positioning frame 202 can be removed, so that the rotating shaft 105 loses its limit. The drive wheel 104 can then be removed. When installing the drive wheel 104 and the rotating shaft 105, the bearing outside the rotating shaft 105 is placed in the bearing groove 203. Then, the positioning frame 202 can be placed on top of the bearing, so that the positioning rod 206 passes through the connecting groove 207 and the positioning pin 208 passes through the positioning hole 209 to position the positioning frame 202. Then, the screw 211 can be rotated in the opposite direction to move the two limit rods 213 away from each other, so that the limit rods 213 extend out of the mounting groove 210 to prevent the positioning pin 208 from falling off. After the positioning frame 202 is positioned, the positioning pin 208 is in close contact with the positioning hole 209, which can ensure the reliability of the positioning frame 202. The support component 2 can stably support the drive wheel 104 and facilitate the disassembly and maintenance of the drive wheel 104.

[0031] When lubricating the bearing outside the rotating shaft 105, push the movable rod 220 upward to compress the telescopic spring 221, causing the limiting plate 223 to move away from the cover plate 218. Then, the limiting plate 223 can be rotated to displace the limiting plate 223 from the cover plate 218, causing the cover plate 218 to lose its limiting position and be opened. Lubricating oil is then added to the adding pipe 217. The lubricating oil enters the bearing groove 203 on the positioning frame 202 through the adding pipe 217. Under the action of gravity, the bearing is fully lubricated. After lubrication, the cover is closed. Plate 218 seals the adding tube 217 with a sealing plug to prevent impurities from entering. Then, the movable rod 220 can be moved upward and the limiting plate 223 can be rotated so that the limiting plate 223 rotates and intersects with the cover plate 218. After releasing the movable rod 220, the limiting plate 223 abuts against the cover plate 218 under the action of the telescopic spring 221, thereby positioning the cover plate 218. This facilitates the lubrication of the rotating shaft 105 by the staff, and allows direct lubrication of the bearing interior, ensuring the stability of the drive wheel 104 rotation and improving practicality.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
