Description

Technical Field

[0001] The utility model relates to the technical field of pumping units, in particular to a drum-type belt structure for a pumping unit. Background Technique

[0002] A pumping unit is an important mechanical device used in the oil extraction industry. It is mainly used to extract crude oil from oil wells. It lifts the oil in the oil well to the ground in a mechanical way and is an indispensable part of oilfield production.

[0003] A pumping unit usually uses a drum-type belt structure to transmit power and lift the sucker rod in the well.

[0004] For the drum-type belt structures of pumping units on the market, in most cases, when the pumping unit suddenly brakes and stops or loses power and other special situations occur, the belt-drum device does not have a certain load-bearing capacity, so it cannot ensure that the counterweight can descend at a slow speed. Moreover, for the drum with a winding method of the pumping unit during the machine moving operation and unloading, unloading devices such as an unloading platform need to be designed, which increases the overall cost of the machine, and thus the drum-type belt structure for the pumping unit needs to be improved. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a drum-type belt structure for a pumping unit, which has the advantages of enhancing the practicability of the drum-type belt mechanism for the pumping unit, etc., and solves the problem that the drum-type belt structure for the pumping unit needs to be improved.

[0006] To achieve the above object, the utility model provides the following technical solution: A drum-type belt structure for a pumping unit, including a drum, a drum shaft is arranged in the middle of the drum, and a winding structure is arranged on the drum.

[0007] The winding structure includes a first rib plate, a second rib plate, a first support plate, a second support plate, a plug plate, a first supporting plate and a second supporting plate. The first rib plate is arranged between the lower end of the drum shaft and the inner bottom wall of the drum. The second rib plate is arranged between the upper end of the drum shaft and the inner top wall of the drum. The first support plate is arranged outside the second rib plate. The second support plate is arranged in the middle of the inside of the drum. The plug plate is arranged outside the middle of the drum. The first supporting plate is arranged at the upper end of the drum. The second supporting plate is arranged at the lower end of the drum.

[0008] Among them, through the two-way winding design of the drum and the belt, the belt in the middle of the drum is connected to the counterweight, and the belts at both ends of the drum are connected to the wellhead. When the motor rotates forward and backward, the belt and the drum are wound and released one by one; this design is helpful in special situations such as the sudden braking and shutdown of the oil pumping unit and power failure. The belt-drum device has a certain bearing capacity (can carry a certain load) to ensure that the counterweight can descend slowly. For the drum with this winding method, there is no need to design unloading devices such as unloading platforms when the oil pumping unit is moved and unloaded, which saves the cost of the whole machine. When the machine is unloaded, the counterweight can be unloaded at the lowest end of the tower, which is safe and reliable.

[0009] Furthermore, the supporting plate 1 is made in a rectangular shape, and the number of the supporting plate 2 is two.

[0010] Furthermore, the number of the support plate 1 and the number of the support plate 2 are both two.

[0011] Furthermore, the two support plates 1 are located at two sides of the reel, and the two support plates 2 are located in the middle of the reel.

[0012] Furthermore, the second rib plate is in a trapezoidal shape, and the first rib plate is in a rectangular shape.

[0013] Among them, rib plate one and rib plate two are collectively referred to as rib plates, and rib plates, also known as bone plates, refer to thin plates used to increase rigidity and strength in metal structures, usually used as connecting plates for ribs. In engineering structures such as ships, airplanes, and large storage tanks, the role of rib plates is very important. It can improve the pressure-bearing capacity and stability of the structure. Rib plates are generally used in conjunction with ribs (such as ribs of ships, beams of airplanes, etc.) to form a spatial grid structure, which can effectively disperse pressure when subjected to stress and improve the overall load-bearing performance.

[0014] Furthermore, a through hole 1 is provided in the supporting plate 1, and a through hole 2 is provided in the supporting plate 2.

[0015] Among them, support plate one and support plate two both refer to plate-like structures used to support, fix or carry other components or loads in buildings, engineering structures or other industrial products. The support plates are usually made of metal, wood, plastic or other engineering materials, and their thickness and size are determined according to the required load-bearing capacity and application environment.

[0016] Furthermore, the number of through hole 1 and through hole 2 are both multiple.

[0017] Furthermore, the structures in the winding structure are all distributed in a symmetrical structure based on the reel.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0019] 1. The drum - type belt structure for the pumping unit has a drum welded by plate parts, with high structural strength and relatively low manufacturing cost.

[0020] 2. The drum - type belt structure for the pumping unit, through the bidirectional winding design of the drum and the belt, has the belt in the middle of the drum connected to the counterweight, and the belts at both ends of the drum connected to the wellhead. When the motor rotates forward and backward, the belt and the drum wind and unwind; this design helps the belt - drum device to have a certain load - bearing capacity (able to carry a certain load) when the pumping unit has special situations such as sudden braking and power failure, ensuring that the counterweight can descend slowly. For the drum with this winding method, when the pumping unit is in the operation of relocating and unloading, there is no need to design unloading devices such as unloading platforms, saving the overall cost of the machine. And when the machine is unloaded, the counterweight can be unloaded at the lowest end of the tower, which is safe and reliable. BRIEF DESCRIPTION OF THE DRAWINGS
