[0001] This utility model relates to the technical field of tower-type pumping unit drive drum structure, specifically a belt clamping structure for an easily adjustable tower-type pumping unit drive drum. Background Technology

[0002] The drive drum of a tower-type pumping unit is a key component of the unit, typically consisting of a motor and drum body. It drives a belt to move the sucker rod up and down in a reciprocating motion to achieve the pumping function. To ensure power transmission, prevent belt slippage, extend belt life, and improve system stability, a belt clamping structure is often required on the drive drum of a tower-type pumping unit. However, the belt clamping structure of the drive drum of a tower-type pumping unit still has some defects in actual use.

[0003] The belt clamping structure of the drive drum of a tower-type pumping unit can only apply a simple clamping force to the belt. After the user adjusts the belt clamping state for the first time, it cannot monitor the clamping effect of the belt in real time or automatically adjust the clamping state. Based on this, we propose a new type of belt clamping structure for the drive drum of a tower-type pumping unit that is easy to adjust. Utility Model Content

The output end of the solar panel is electrically connected to the input end of the photovoltaic controller and the storage battery, making it easy to use solar energy to supplement its own required power and realizing the advantage of energy saving.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The belt clamping structure of the tower-type pumping unit drive drum is optimized by setting assembly blocks, etc. The user can use the positioning and plugging structure formed by the assembly blocks and assembly slots, and the locking and fixing effect formed by the locking plates and screws, to fix the clamping spring with appropriate preload between the upper adjustable pressure plate, the lower adjustable pressure plate and the frame.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 The present invention provides an embodiment of a belt pressing structure for a tower-type pumping unit drive drum that is easy to adjust, including a drive drum 4, a belt 5 connected to the drive drum 4, and an upper adjustable pressure plate 3 and a lower adjustable pressure plate 6 respectively installed on the top and bottom of the belt 5.

The frame 7 is provided with guide slide openings 14 that match the guide slide rods 10. The upper adjustable pressure plate 3 and the lower adjustable pressure plate 6 are evenly installed with compression springs 12 between them and the frame 7.

[0026] The top and bottom of the compression spring 12 are fixed with mounting blocks 19, and the upper adjustable pressure plate 3, the lower adjustable pressure plate 6 and the frame 7 are all provided with mounting slots 8 that match the mounting blocks 19.

[0027] A locking piece 9 is provided on the assembly insert 19, and a screw is connected to the locking piece 9;

[0028] The compression spring 12 has an internal telescopic rod connected to it;

[0029] In use, the user can use the positioning and plugging structure formed by the assembly plug 19 and the assembly slot 8, together with the locking and fixing action formed by the locking plate 9 and the screw, to fix the compression spring 12 with an appropriate preload between the upper adjustable pressure plate 3, the lower adjustable pressure plate 6 and the frame 7. Then, by manually adjusting and replacing the compression spring 12 with different preloads, the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6 can apply appropriate pressure to the top and bottom of the belt 5 to ensure that the belt is in a compressed state and to prevent the belt from slipping during operation.

[0030] The top and bottom of the frame 7 are respectively equipped with hydraulic telescopic cylinders 13 that match the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6. The inner side wall of the frame 7 is equipped with a PLC controller 2. The top of the frame 7 is equipped with a top protective canopy 1. The top of the top protective canopy 1 is covered with a solar panel 17.

[0031] Two pressure sensing plates 11 are provided, and pressure sensors are installed inside the pressure sensing plates 11.

[0032] The output end of the hydraulic telescopic cylinder 13 is fitted with an anti-slip pressure plate 15;

[0033] In use, the pressure sensing plates 11 equipped with pressure sensors installed on the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6 will monitor the pressure between them and the belt 5 in real time and send the monitored data to the PLC controller 2. When the PLC controller 2 detects that the pressure value has decreased due to pressure deformation caused by damage to the clamping spring 12 or insufficient clamping effect, the PLC controller 2 will activate the hydraulic telescopic cylinder 13 to drive the anti-slip pressure plate 15 at its output end to actively apply pressure to the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6, thereby achieving active clamping protection for the belt 5. The PLC controller 2 will also issue an alarm to remind the staff to replace and maintain the clamping spring 12 in time. This makes the device realize the advantages of clamping effect monitoring and automated emergency handling, and the safety effect is higher.

[0034] The hydraulic telescopic cylinder 13 and the frame 7 are connected by a plug-in joint. The hydraulic telescopic cylinder 13 and the frame 7 are connected by screws to form a disassembly and installation structure, which makes it easy to disassemble and maintain the hydraulic telescopic cylinder 13.

[0035] A photovoltaic controller 16 and a storage battery 18 are installed sequentially at the bottom of the interior of the top protective canopy 1. The output end of the solar panel 17 is electrically connected to the input end of the photovoltaic controller 16 and the storage battery 18, making it easy to use solar energy to supplement its own required power and realizing the advantage of energy saving.

[0036] In use, the following steps are taken: First, the user secures the frame 7 and the tower-type pumping unit with screws. In actual use, the user can utilize the positioning and insertion structure formed by the assembly plug 19 and the assembly slot 8, along with the locking action formed by the locking plate 9 and the screws, to secure the appropriate preload spring 12 between the upper adjustable pressure plate 3, the lower adjustable pressure plate 6, and the frame 7. Then, by manually adjusting and replacing the pressure spring 12 with different preload values, the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6 apply appropriate pressure to the top and bottom of the belt 5, ensuring the belt is in a compressed state and preventing belt slippage during operation. Simultaneously, the pressure sensing plates 11 equipped with pressure sensors installed on the upper and lower adjustable pressure plates 3 and 6 monitor the pressure between them and the belt 5 in real time and send the monitored data to the PLC controller 2. When damage to the pressure spring 12 is detected... When the pressure value decreases due to pressure deformation or insufficient clamping effect, the PLC controller 2 will activate the hydraulic telescopic cylinder 13 to drive the anti-slip pressure plate 15 at its output end to actively apply pressure to the upper adjustable pressure plate 3 and the lower adjustable pressure plate 6, thereby achieving active clamping protection for the belt 5. The PLC controller 2 will also issue an alarm to remind the staff to replace and maintain the clamping spring 12 in time. This gives the device the advantages of clamping effect monitoring and automated emergency handling, resulting in higher safety. In addition, on the one hand, by adding a top protective canopy 1 to the top of the device, the electrical components on the device and the corresponding drive roller 4 and belt 5 can be protected from sun and rain, reducing the problem of equipment corrosion. On the other hand, the solar panel 17 absorbs solar energy from the external environment and converts the solar energy into electrical energy through the photovoltaic controller 16 and stores it in the battery 18 for its own use. This gives the device the advantage of energy saving and makes it more energy-efficient during long-term operation.
