At the same time, the transmission device 6 is the existing technology, and the transmission device 6 includes a reduction device inside. At the same time, the driving motor 2 is a switched reluctance speed regulation commutation motor.

[0030] A first spring 506 is sleeved on the surface of the fixed plate 504. One side surface of the first spring 506 is fixedly connected to the slider 502. A baffle 507 is fixedly connected to the other side surface of the first spring 506. The baffle 507 is fixedly connected to the sleeve 501. The internal snap-fitting connection of the snap-fitting groove 505 has a snap-fitting ball 508. A side surface of the fixed plate 504 away from the snap-fitting groove 505 is symmetrically provided with a connecting groove 509. The internal snap-fitting connection of the connecting groove 509 has a limiting ball 510. A pressing block 511 is slidably connected to the inside of the sleeve 501. The pressing block 511 is connected to the fixed plate 504. An extension plate 512 is fixedly connected to the side surface of the sleeve 501 near the top. A clamping rod 513 is connected through the middle of the top surface of the extension plate 512, and a second spring 514 is sleeved on the side surface of the clamping rod 513 near the bottom. A fitting plate 515 is fixedly connected to the bottom surface of the second spring 514. The top surface of the second spring 514 is fixedly connected to the extension plate 512, and the bottom surface of the fitting plate 515 is fitted and connected to the sleeve 501.

Clamping grooves 9 are symmetrically provided on both sides of the transmission device 6 near the bottom, and the clamping grooves 9 are clamped and connected to the clamping rod 503. Figure 3 , 4 As shown, by pulling the engaging rod 513 to separate the engaging rod 513 from the engaging groove 516, the pressing block 511 is pressed so that the pressing block 511 is squeezed with the engaging ball 508. After the engaging ball 508 is squeezed, it moves to one side of the engaging groove 505. At the same time, because the engaging groove 505 is an inclined surface and the pressing block 511 is pressed, the engaging ball 508 presses the fixing plate 504, so that the engaging ball 508 completely enters the engaging groove 505. When the engaging ball 508 enters the engaging groove 505, the fixing plate 504 moves toward the pressing block 511. The movement of the fixing plate 504 can drive the slider 502 and the movement of the clamping rod 503, so that the clamping rod 503 is separated from the clamping slot 9, by loosening the clamping rod 513, the clamping rod 513 is clamped together with the clamping slot 516 under the action of the second spring 514, thereby completing the limitation of the pressing block 511, making it convenient to quickly disassemble and install the transmission device 6, thereby improving the maintenance efficiency of the transmission device 6. At the same time, the first spring 506 and the second spring 514 are rubber composite springs in the prior art, and the elastic force of the rubber composite spring is relatively large, so that the clamping rod 503 and the clamping slot 9 are clamped more tightly, and the clamping rod 513 and the clamping slot 516 are clamped more tightly.

[0031] A plurality of extension blocks 10 are symmetrically installed on both sides of the rope wheel 7. A limit rod 11 is connected to the side surface of the extension block 10 away from the rope wheel 7. A third spring 12 is sleeved on the side surface of the limit rod 11 near the bottom.

The bottom surface of the fitting block 13 is fitted and connected to the rotating rod 3. Limiting grooves 14 are symmetrically provided on both sides of the surface of the rotating rod 3. The limiting grooves 14 are engaged and connected with the limiting rod 11. Figure 5 As shown, the third spring 12 is also a rubber composite spring in the prior art. The elastic force of the rubber composite spring is relatively large, so that the limit rod 11 can be more tightly engaged with the limit groove 14 under the action of the third spring 12, thereby preventing the rope wheel 7 from falling off when the rotating rod 3 drives the rope wheel 7 to rotate.

[0032] Working principle: Before using the pumping assembly of this tower type pumping unit, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 5 As shown, first, when the transmission device 6 needs to be inspected, repaired and disassembled, the clamping rod 513 is pulled to separate the clamping rod 513 from the clamping groove 516, and then the pressing block 511 is pressed to squeeze the pressing block 511 and the clamping ball 508. After the clamping ball 508 is squeezed, it moves to one side of the clamping groove 505. At the same time, because the clamping groove 505 is an inclined surface and the pressing block 511 squeezes, the clamping ball 508 squeezes the fixing plate 504, so that the clamping ball 508 completely enters the inside of the clamping groove 505, and the clamping ball 508 When entering the locking groove 505, the fixing plate 504 moves in the direction of the pressing block 511. The movement of the fixing plate 504 can drive the movement of the slider 502 and the locking rod 503, so that after the locking rod 503 is separated from the locking groove 9, the locking rod 513 is loosened so that the locking rod 513 is engaged with the locking groove 516 under the action of the second spring 514, thereby completing the limiting of the pressing block 511, making it convenient to quickly disassemble and install the transmission device 6, thereby improving the maintenance efficiency of the transmission device 6.

[0033] Secondly, by setting the extension block 10, the limit rod 11, the third spring 12 and the fitting block 13, when disassembling the rope wheel 7, the limit rod 11 can be pulled by a tool, so that the limit rod 11 is separated from the limit groove 14, which makes it easy to disassemble the rope wheel 7. During installation, by loosening the limit rod 11, the limit rod 11 is re-engaged with the limit groove 14 under the action of the third spring 12, which makes it easy to install the rope wheel 7, thereby improving the work efficiency of the staff.
