Description

Technical Field

[0001] This invention relates to the field of oilfield development technology and is a tool for quickly adjusting the anti-impact distance of an oil pumping unit. Background Technology

[0002] Currently, in the crude oil extraction process of onshore oilfields in China, most oil wells rely on mechanical oil extraction. Among mechanical oil extraction methods, the walking beam pumping unit accounts for the highest proportion of production. When using the walking beam pumping unit, adjusting the anti-surge distance at the wellhead is a conventional and cost-effective way to increase production. It is also one of the most frequently performed wellhead operations. In traditional anti-surge distance adjustment operations, operators usually use tools such as pipe wrenches, levers, and polished rod clamps in combination to adjust the anti-surge distance of the pumping unit well. The operation process is not only time-consuming but also prone to mechanical injuries. In addition, due to the high altitude of the operation position, operators usually need to climb onto the insulated box to perform the operation, which poses a risk of falling from height. Therefore, there is an urgent need to develop a special tool for safe, efficient, and quick anti-surge distance adjustment. Summary of the Invention

[0003] This invention provides a tool for quickly adjusting the anti-collision distance of an oil pumping unit, which overcomes the shortcomings of the prior art and can effectively solve the problems of long operation time and high operation risk in existing anti-collision distance adjustment operations.

[0004] The technical solution of this invention is achieved through the following measures: A tool for quickly adjusting the anti-impact distance of a pumping unit, comprising a polished rod sleeve, a left connecting rod, a right connecting rod, a return spring, a connecting handle, an operating lever handle, and a connecting short connector. The polished rod sleeve is composed of a left half-cylinder and a right half-cylinder joined together. The outer side of the left half-cylinder is fixedly connected to the rear end of the left connecting rod, and the outer side of the right half-cylinder is fixedly connected to the rear end of the right connecting rod. The middle parts of the left connecting rod and the middle parts of the right connecting rod are hinged together. The left half-cylinder and the right half-cylinder can be... When the front ends of the left and right connecting rods are brought together, they move away from each other. A return spring is connected between the front ends of the left and right connecting rods to bring the left and right half-cylinders together. A connecting handle is fixedly connected to the lower side of the front end of the left and right connecting rods respectively. There are two operating rod handles, which are connected together in an X-shape. A connecting short connector is fixedly connected to the upper end of each operating rod handle. The two connecting short connectors and the two connecting handles are sleeved together in a corresponding manner.

[0005] The following are further optimizations and / or improvements to the above-mentioned invention:

[0006] The aforementioned connecting handle is a vertically arranged columnar structure, and the connecting short is a vertically arranged sleeve-like structure. The inner diameter of the connecting short is slightly larger than the diameter of the connecting handle. The two connecting shorts and the two connecting handles are connected together in an inner and outer sleeve manner, corresponding to each other.

[0007] The aforementioned left and right connecting rods are both horizontally positioned, while the operating lever handle is inclined from front to back and from bottom to top, with an angle of 120 to 160 degrees between the operating lever handle and the connecting short circuit.

[0008] The length of the aforementioned bare rod sleeve is 20 cm, and the length of the operating rod handle is 120 cm to 150 cm.

[0009] The left connecting rod includes a left straight rod segment and a left diagonal rod segment connected sequentially from back to front. The left straight rod segment is arranged in a front-to-back direction, and the left diagonal rod segment is arranged from front to back and from left to right. The right connecting rod includes a right straight rod segment and a right diagonal rod segment connected sequentially from back to front. The right straight rod segment is arranged in a front-to-back direction, and the right diagonal rod segment is arranged from front to back and from right to left. Connecting plates are fixedly connected to the upper and lower sides of the front end of the right straight rod segment. A pin hole is provided at the front end of the left straight rod segment corresponding to the position of the connecting plate. A pin is movably inserted in the pin hole. The upper and lower ends of the pin are fixedly connected to the upper and lower connecting plates respectively. A return spring is connected between the front end of the left diagonal rod segment and the front end of the right diagonal rod segment.

[0010] The present invention has a reasonable structure. Through the design of this application, the entire process of adjusting the anti-collision distance is simple, convenient and easy to implement, saving time and effort. During the entire operation, the operator only needs to stand on the ground and hold the lower end of the two operating rod handles to carry out the operation. There is no need for the operator to climb to a height. The operator stays away from the pumping unit suspension rope device and the polished rod, and the operation risk is small.

Detailed Implementation

[0015] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0016] In this invention, for ease of description, the description of the relative positions of the components is based on the appendix to the specification. Figure 1 The layout is described using a diagrammatic method, such as front, back, top, bottom, left, right, etc. The positional relationships are determined based on the layout direction of the attached diagram in the instruction manual.

[0017] The present invention will be further described below with reference to embodiments and accompanying drawings:

[0018] As attached Figure 1-3 As shown, the quick anti-slip tool for the pumping unit includes a polished rod sleeve, a left connecting rod, a right connecting rod, a return spring 3, a connecting handle 4, an operating lever handle 5, and a connecting short connector 6. The polished rod sleeve is composed of a left half-cylinder 1 and a right half-cylinder 2 joined together. The outer side of the left half-cylinder 1 is fixedly connected to the rear end of the left connecting rod, and the outer side of the right half-cylinder 2 is fixedly connected to the rear end of the right connecting rod. The middle parts of the left and right connecting rods are hinged together. The left half-cylinder 1 and the right half-cylinder 2 can be connected at the front end of the left connecting rod and the right half-cylinder 2. When the front ends of the connecting rods come together, they move away from each other. A return spring 3 is connected between the front ends of the left and right connecting rods to bring the left half-cylinder 1 and the right half-cylinder 2 together. A connecting handle 4 is fixedly connected to the lower front end of the left connecting rod and the lower front end of the right connecting rod, respectively. There are two operating rod handles 5, which are connected together in an X-shape. A connecting short connector 6 is fixedly connected to the upper end of each operating rod handle 5. The two connecting short connectors 6 and the two connecting handles 4 are connected together in a corresponding manner.

[0019] According to requirements, the return spring 3 is a helical compression spring. When the left half-cylinder 1 and the right half-cylinder 2 are joined together, the return spring 3 is in a compressed state. When installing the polished rod sleeve, the operator stands on the ground and applies force to the lower ends of the two operating rod handles 5, causing the upper ends of the two operating rod handles 5 to move closer together. This causes the front ends of the left connecting rod and the front ends of the right connecting rod to move closer together against the elastic force of the return spring 3, thus moving the left half-cylinder 1 and the right half-cylinder 2 away from each other. After moving the left half-cylinder 1 and the right half-cylinder 2 to the outside of the polished rod, located between the upper clamp of the pumping unit suspension rope device and the polished rod clamp, the force applied to the lower ends of the two operating rod handles 5 to move them closer together is removed. At this time, the front ends of the left connecting rod and the front ends of the right connecting rod move away from each other under the elastic force of the return spring 3, thus moving the left half-cylinder 1 and the right half-cylinder 2 closer together. The two rods are brought together and held on the outside of the polished rod. Then, the operating lever handle 5 is lowered to separate the connecting handle 4 and the connecting short connector 6. When the polished rod sleeve is to be removed from the polished rod, the two connecting short connectors 6 and the two connecting handles 4 are connected together one by one. Then, force is applied to the lower end of the two operating lever handles 5 to bring the upper end of the two operating lever handles 5 together, so that the left half of the cylinder 1 and the right half of the cylinder 2 are separated from each other, and the polished rod sleeve can be removed. Through the design of this application, the time for adjusting the polished rod clamp is saved, the efficiency of adjusting the anti-impact distance is improved, and the entire anti-impact distance adjustment operation is simple, convenient, easy to implement, time-saving and labor-saving. During the entire operation, the operator only needs to stand on the ground and hold the lower end of the two operating lever handles 5 to perform the operation. There is no need for the operator to climb to work. The operator is away from the pumping unit suspension rope device and the polished rod, and the operation risk is small.

[0020] The above embodiments can be further optimized and / or improved according to actual needs:

[0021] As attached Figure 1-2 As shown, the connecting handle 4 is a vertically oriented columnar structure, and the connecting short connector 6 is a vertically oriented sleeve-like structure. The inner diameter of the connecting short connector 6 is slightly larger than the diameter of the connecting handle 4. The two connecting short connectors 6 and the two connecting handles 4 are connected together in a one-to-one correspondence. This facilitates quick connection and disconnection between the connecting handles 4 and the connecting short connectors 6.

[0022] As attached Figure 1-2 As shown, both the left and right connecting rods are horizontally positioned, while the operating lever 5 is angled from front to back and from bottom to top. The angle between the operating lever 5 and the connecting short connector 6 is between 120 and 160 degrees. This allows operators to easily control the front ends of the left and right connecting rods to move away from or towards each other by operating the operating lever 5 while standing on the ground. Specifically, in this embodiment, the angle between the operating lever 5 and the connecting short connector 6 is 150 degrees.

[0023] Specifically, the length of the bare rod sleeve is 20 cm, and the length of the operating rod handle 5 is 120 cm to 150 cm. Specifically, the length of the operating rod handle 5 is 120 cm.

[0024] As attached Figure 1-3 As shown, the left connecting rod includes a left straight rod segment 7 and a left oblique rod segment 8 connected sequentially from back to front. The left straight rod segment 7 is arranged in a front-back direction, and the left oblique rod segment 8 is arranged obliquely from front to back and from left to right. The right connecting rod includes a right straight rod segment 9 and a right oblique rod segment 10 connected sequentially from back to front. The right straight rod segment 9 is arranged in a front-back direction, and the right oblique rod segment 10 is arranged obliquely from front to back and from right to left. The upper and lower ends of the front end of the right straight rod segment 9 are fixedly connected to the connecting plates 11 on both sides. The front end of the left straight rod segment 7 corresponding to the position of the connecting plate 11 is provided with a pin hole that passes through from top to bottom. A pin is movably inserted in the pin hole. The upper and lower ends of the pin are fixedly connected to the connecting plates 11 on the upper and lower sides respectively. The return spring 3 is connected between the front end of the left oblique rod segment 8 and the front end of the right oblique rod segment 10. Therefore, when the front ends of the left connecting rod and the right connecting rod approach each other, the left half-cylinder 1 and the right half-cylinder 2 move away from each other, and when the front ends of the left connecting rod and the right connecting rod move away from each other, the left half-cylinder 1 and the right half-cylinder 2 approach each other.

[0025] The above technical features constitute the preferred embodiment of the present invention, which has strong adaptability and optimal implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the requirements of different situations.
