Description

Technical Field

[0001] This utility model relates to the field of oil pumping machine technology, specifically a chain-type high-efficiency oil pumping machine. Background Technology

[0002] Chain pumping units utilize a track chain reversing mechanism to convert the rotary motion of the power unit into reciprocating motion. The high-speed rotation of the electric motor, after reduction, drives the drive sprocket to move the track chain. A special link on the track chain connects to the reciprocating frame. When the track chain makes a vertical circular motion, it drives the reciprocating frame to move up and down in the frame guide rails. The wire rope on the frame, after passing through the top wheel, also drives the sucker rod string lowered into the well to reciprocate.

[0003] For example, the authorization announcement number "CN202970638U" describes a chain-type high-efficiency pumping unit. This unit utilizes a sliding sprocket installed inside the balance box. Under the tension of the chain, the sprocket slides up and down along a track, reducing the lifting force by half for the same weight of crude oil. This significantly reduces the power consumption of the electric motor, achieving energy savings. However, current chain-type high-efficiency pumping units are typically installed above oil wells in oil fields, with most exceeding tens of meters in height. Many sprockets and pulleys are located high on the pumping tower, requiring personnel to ascend for maintenance and lubrication as usage time increases. Workers usually use a vertical ladder to reach this height, which lacks footholds and safety equipment, making the maintenance process for chain-type high-efficiency pumping units quite dangerous. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high risk in the maintenance process of existing chain-type high-efficiency oil pumping units, and to propose a chain-type high-efficiency oil pumping unit.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a chain-type high-efficiency oil pumping unit, including a chain-type oil pumping unit body, a drive motor and pulleys. The drive motor is fixedly installed on one side of the lower end of the chain-type oil pumping unit body, and the pulleys are rotatably installed on one side of the top end of the chain-type oil pumping unit body. The outer wall of the chain-type oil pumping unit body is provided with a multi-level safety climbing auxiliary structure, and the lower end of the chain-type oil pumping unit body is provided with a stable support structure.

[0007] Preferably, the multi-level safety climbing auxiliary structure includes steps and windbreaks. Multiple steps are fixedly installed on the outer wall of the chain-type pumping unit body.

[0009] Preferably, the stable support structure includes a base and a reinforced base layer. The base is fixedly installed at the lower end of the chain-type pumping unit body. The lower end of the base is fixedly connected to the reinforced base layer. An anchoring cone is fixedly installed at the lower end of the base.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example 1:

[0022] Please see Figure 1-6 In this embodiment, a chain-type high-efficiency pumping unit includes a chain-type pumping unit body 1, a drive motor 2, and a pulley 4. The drive motor 2 is fixedly installed on one side of the lower end of the chain-type pumping unit body 1. The drive motor 2, pulley 4, sucker rod 3, and chain-type pumping unit body 1 are all prior art disclosed in the prior art document authorized by the prior art publication number "CN202970638U" entitled "A Chain-Type High-Efficiency Pumping Unit". The drive motor first rotates clockwise and counterclockwise, driving the reducer to rotate in the same direction. Under the action of the sprocket, the chain drives the balance box to move upward, and the pulley rotates clockwise.

[0023] The lifting rod is sent down into the well. Once the lifting rod reaches the designated position, the drive motor rotates clockwise and counterclockwise, driving the reducer to rotate in the same direction. Under the action of the sprocket, the chain drives the balance box to move downward. The pulley rotates counterclockwise, lifting the lifting rod from downhole to the surface, thus completing one oil production process. The pulley 4 is rotatably installed on one side of the top of the chain-type pumping unit body 1. The outer wall of the chain-type pumping unit body 1 is equipped with a multi-level safety climbing auxiliary structure 6, and the lower end of the chain-type pumping unit body 1 is equipped with a stable support structure 7.

[0024] The multi-level safety climbing auxiliary structure 6 includes steps 61 and windbreaks 66. Multiple steps 61 are fixedly installed on the outer wall of the chain-type pumping unit body 1. The steps 61 are prefabricated and welded from carbon steel and fixed to one side of the outer wall of the chain-type pumping unit body 1. Through holes 64 are fixedly drilled on the inner side of the multiple steps 61. The through holes 64 facilitate workers to climb to the next step 61 on the vertical ladder 63. The vertical ladder 63 is fixedly installed on the inner side of the multiple through holes 64. Safety ropes 65 are fixedly connected to one side of the outer wall of the multiple vertical ladders 63. The safety ropes 65 are made of high-strength, tensile-resistant steel cables.

[0025] Workers can attach their safety buckles to the safety rope 65 to provide cushioning protection in the event of a fall. Multiple steps 61 are fixedly connected to the upper edge of the steps 61 with guardrails 62. The guardrails 62 are made of stainless steel metal railings welded to the edge of the steps 61. The guardrails 62 can reduce the occurrence of workers falling from heights. Two wind deflectors 66 are fixedly installed on both sides of the outer wall of the chain-type pumping unit body 1. The wind deflectors 66 extend from both sides of the chain-type pumping unit body 1, which can reduce the impact of strong winds on workers on the steps 61.

[0026] The steps 61 are prefabricated and fixed to one side of the outer wall of the chain-type pumping unit body 1 by welding carbon steel. The through holes 64 facilitate workers to climb to the next step 61 on the vertical ladder 63. The safety rope 65 is made of high-strength and tensile-resistant steel cable. Workers can attach their safety buckles to the safety rope 65 to provide cushioning protection in case of a fall. The enclosure 62 is made of stainless steel metal railings welded to the edge of the steps 61.

[0027] The enclosure 62 can reduce the occurrence of workers falling from heights. The wind deflector 66 extends from both sides of the chain-type pumping unit body 1, which can reduce the impact of strong winds on workers on the steps 61. The multi-level ladder on the outside of the pumping unit provides a resting place for maintenance personnel, which can also play a good protective role and improve the maintenance safety of the chain-type high-efficiency pumping unit.

[0028] Multiple steps 61 are distributed parallel to each other at equal intervals. The top of the vertical ladder 63 is level with the top of the chain pumping unit body 1, and the bottom of the vertical ladder 63 is at the same height as the bottom of the chain pumping unit body 1.

[0029] The stable support structure 7 includes a base 71 and a reinforced base 72. The base 71 is fixedly installed at the lower end of the chain-type pumping unit body 1. The base 71 is made of a single piece of high-strength carbon steel base. The base 71 is welded to the vertically tall chain-type pumping unit body 1. The lower end of the base 71 is fixedly connected to the reinforced base 72, which is made of integrally cast reinforced concrete. The reinforced base 72 is fixed deep underground, which can reduce pressure by increasing the contact area.

[0030] An anchoring cone 73 is fixedly installed at the lower end of the base 71. The anchoring cone 73 is made of high carbon steel and is vertically driven deep into the ground. The lower ends of multiple anchoring cones 73 are fixedly connected to bifurcated ends 74. The bifurcated ends 74 improve the grip by opening outwards, which can provide relatively stable support for chain-type high-efficiency oil pumping units that are tens of meters high. Anti-bending plates 75 are fixedly connected to the outer walls of multiple anchoring cones 73. The anti-bending plates 75, together with multiple transverse strips 76, are clamped to the outside of the anchoring cones 73. The anti-bending plates 75 can reduce the stress deformation of the anchoring cones 73 underground. Transverse strips 76 are fixedly connected between multiple anti-bending plates 75.

[0031] Working principle:

[0032] The chain-driven high-efficiency oil pumping unit works by first rotating the drive motor clockwise and counterclockwise, which in turn drives the reducer to rotate in the same direction. The chain, driven by the sprockets, moves the balance box upwards. The pulleys rotate clockwise, sending the lifting rod down into the well. Once the lifting rod reaches the designated position, the drive motor rotates clockwise and counterclockwise, driving the reducer to rotate in the same direction. The chain, driven by the sprockets, moves the balance box downwards. The pulleys rotate counterclockwise, lifting the lifting rod from the well to the surface, thus completing one oil extraction cycle. This chain-driven oil pumping operation, with its continuous upward movement of the lifting rod, ensures a high efficiency rate.

[0033] Chain-type high-efficiency oil pumping unit safety climbing and maintenance structure:

[0034] The steps 61 are prefabricated and fixed to one side of the outer wall of the chain-type pumping unit body 1 by welding carbon steel. The through holes 64 facilitate workers to climb to the next step 61 on the vertical ladder 63. The safety rope 65 is made of high-strength and tensile-resistant steel cable. Workers can attach their safety buckles to the safety rope 65 to provide cushioning protection in case of a fall. The enclosure 62 is made of stainless steel metal railings welded to the edge of the steps 61. The enclosure 62 can reduce the occurrence of workers falling from heights. The wind deflectors 66 extend from both sides of the chain-type pumping unit body 1 to reduce the impact of strong winds on workers on the steps 61. The multi-level ladders on the outside of the pumping unit provide a resting place for maintenance personnel.

[0035] Stable support structure of chain-type high-efficiency oil pumping unit:

[0036] The base 71 is made of a single piece of high-strength carbon steel. The base 71 is welded to the vertically tall chain-type pumping unit body 1. The reinforced base 72 is made of integrally cast reinforced concrete. The reinforced base 72 is fixed deep underground and can reduce pressure by increasing the contact area. The anchoring cone 73 is made of high-carbon steel and is vertically driven deep into the ground. The lower ends of multiple anchoring cones 73 are fixedly connected to bifurcated ends 74. The bifurcated ends 74 improve the grip by opening outwards. This can also provide relatively stable support for the chain-type high-efficiency pumping unit that is tens of meters high. The anti-bending plate 75, together with multiple transverse strips 76, is clamped on the outside of the anchoring cone 73. The anti-bending plate 75 can reduce the stress deformation of the anchoring cone 73 underground.

[0037] Example 2:

[0038] Please see Figure 1-6 In this embodiment, a chain-type high-efficiency pumping unit also includes a traction steel cable 5 movably sleeved on the outer side of the pulley 4, and a sucker rod 3 fixedly connected to the lower end of the traction steel cable 5. After the drive motor 2 is connected to the power supply and started, it can drive the top pulley 4 to rotate according to the transmission structure inside the chain-type pumping unit body 1.

[0039] Then, the pulley 4 changes direction to drive the traction cable 5 to drive the sucker rod 3 to move up and down. Two diagonal supports 8 are fixedly installed on the rear side of the outer wall of the chain-type pumping unit body 1. The diagonal supports 8 are two parallel high-carbon steel columns to improve the support of the chain-type pumping unit body 1. The other end of the two diagonal supports 8 is fixedly connected to the housing of the drive motor 2.

[0040] Working principle:

[0041] After the drive motor 2 is connected to the power supply and started, it can drive the top pulley 4 to rotate according to the internal transmission structure of the chain pumping unit body 1. Then, the pulley 4 changes direction and drives the traction steel cable 5 to drive the sucker rod 3 to move up and down. Two diagonal supports 8 are fixedly installed on the rear side of the outer wall of the chain pumping unit body 1. The diagonal supports 8 are two parallel high carbon steel columns, which improve the support of the chain pumping unit body 1.
