Description

Technical Field

[0001] The utility model relates to the technical field of oil extraction equipment, in particular to a belt type oil pumping unit moving device. Background Art

[0002] As a device widely used in the field of oil extraction, the belt type oil pumping unit plays a crucial role in oilfield production. However, with the continuous progress of oilfield development, the needs for adjusting the layout of oil wells, maintaining and updating equipment, and optimizing extraction processes are increasing day by day. This makes the belt type oil pumping unit need to be moved frequently. However, there are many deficiencies in the existing moving methods and technologies of the belt type oil pumping unit, which seriously restrict the efficiency, safety, and applicability of the moving operation.

[0003] Traditional moving methods of belt type oil pumping units often require a large amount of manpower, material resources, and complex mechanical equipment. For example, during the moving process, a large crane is needed to lift the oil pumping unit body, then it is transported by a transport vehicle, and finally reinstalled. This operation method not only takes a lot of time for equipment disassembly, hoisting, and assembly, but also has extremely high requirements for the technical level and experience of operators. Every link needs to be carefully operated. A little carelessness may cause equipment damage or moving failure. In addition, due to the collaborative operation of multiple equipment and processes, any problem in any link may affect the entire moving progress, resulting in an extended moving time,进而影响油田的正常生产,造成经济损失,滚轮是抽油机移机过程中实现设备移动的关键部件,然而,现有的抽油机滚轮设计存在缺陷,拆装过程极为不便,在安装滚轮时,需要将滚轮与抽油机底座进行精确对接和固定,由于滚轮结构复杂,安装过程中需要多人协作,反复调整位置和角度,以确保滚轮安装牢固且能够正常转动,而在拆卸滚轮时,同样面临诸多困难,需要使用专门的工具拆卸固定螺栓,由于螺栓长期暴露在户外环境中,容易生锈和卡死,增加了拆卸难度,此外,在拆卸和安装过程中,还需要对滚轮及周边部件进行防护,避免碰撞和损坏,这进一步降低了移机效率。 Content of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a belt type oil pumping unit moving device to solve the problems of cumbersome moving operation, inconvenient disassembly and assembly of rollers, and easy loss of existing oil pumping units.

[0005] Based on the above purpose, the utility model provides a belt type oil pumping unit moving device, which includes: a base, on one side of the base, an oil pumping unit body is installed, and on the other side of the base, a moving component is slidably installed, and the moving component is used to support the base and the oil pumping unit body installed on the base in a movable state.

[0006] Preferably, the relocation assembly includes a second sliding plate slidably mounted on one side of the base, a first sliding plate fixedly mounted on one side of the second sliding plate, two connecting plates symmetrically fixedly mounted on the first sliding plate, a hydraulic cylinder rotatably mounted between the connecting plates, support plates fixedly mounted on the symmetrical sides of the second sliding plate, a transfer wheel slidably mounted between the two support plates, and the output end of the hydraulic cylinder connected to the transfer wheel.

[0007] Preferably, a sliding plate is fixedly installed on the support plate, and a first sliding groove and a second sliding groove are provided on one side of the base. The sliding plate is slidably installed in the second sliding groove, and the second sliding plate is slidably installed in the first sliding groove.

[0008] Preferably, the support plate has a first sliding groove, the output end of the hydraulic cylinder is equipped with a connecting column, the connecting column is slidably installed in the first sliding groove, and a first mating plate is fixedly installed on one side of the connecting column.

[0009] Preferably, a limiting groove is formed on one side of the interior of the second slide plate, and a plurality of return springs are fixedly installed in the limiting groove. The other ends of the plurality of return springs are jointly installed with a receiving plate. A second mating plate is fixedly installed on one side of the receiving plate, and one side of the second mating plate is adapted to one side of the first mating plate.

[0010] Preferably, the support plate has an opening that penetrates the first sliding groove, and the receiving plate is adapted to the opening.

[0011] Preferably, mating seats are fixedly installed on both symmetrical sides of the support plate, and a second sliding groove is provided in the mating seat, and the receiving plate is slidably installed in the second sliding groove.

[0012] The beneficial effects of this utility model are: 1. This type of belt-driven pumping unit relocation device, equipped with a hydraulic cylinder, a transfer wheel, and a connecting column, allows the hydraulic cylinder to drive the connecting column outward along a set trajectory within the first sliding groove of the support plate during relocation. The connecting column connects to the transfer wheel and initially drives the transfer wheel to slide horizontally within the first sliding groove. When the transfer wheel slides to the area of ​​the second sliding groove between the support plates, the unique structure of the second sliding groove guides the movement direction of the transfer wheel, causing its movement direction to gradually change from horizontal to vertical under structural constraints, thus realizing the transformation from a contracted state to a supported state, i.e., completing the "flipping and unfolding".

[0013] 2. This type of belt-driven pumping unit relocation device, equipped with a first mating plate, a second mating plate, and return springs, etc., drives the connecting column to slide within the first sliding groove at the output end of the hydraulic cylinder. This causes the transfer wheel to "flip and unfold" from a horizontal sliding position to a vertical one. When the hydraulic cylinder further actuates, the first mating plate connected to the output end contacts and engages with the second mating plate mounted on the receiving plate. During this process, the first mating plate moves along the second mating plate, causing the transfer wheel to gradually enter the second sliding groove area. Simultaneously, multiple return springs within the limiting groove are compressed, storing elastic energy. When the transfer wheel fully enters the second sliding groove area, the return springs release the stored energy. The stored elastic energy pushes the support plate outward, which in turn pushes the transfer wheel further out and stabilizes it, ultimately achieving stable support and establishing a movable state for the pumping unit body. This coordination method allows the transfer wheel to stably transition from a retracted state to a supported state, providing reliable support for the pumping unit body and ensuring its smooth movement during relocation, thus improving the safety and reliability of the relocation. At the same time, the reset spring gives the transfer wheel a certain degree of buffering and self-adaptation during extension and support, enabling it to better adapt to different ground conditions and relocation needs, further improving the applicability of the device and the efficiency of the relocation.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0019] like Figures 1 to 5 As shown, the belt-driven pumping unit relocation device includes: a base 1, a pumping unit body 2 installed on one side of the base 1, and a relocation assembly slidably installed on the other side of the base 1. The relocation assembly is used to support the base 1 and the pumping unit body 2 installed on the base 1 in a movable state. This belt-driven pumping unit relocation device has a pumping unit body 2 fixedly installed on one side of the base 1 and a sliding relocation component on the other side. When relocation is required, the relocation component slides along a set trajectory on the base 1 and unfolds the relocation wheel 7. The relocation wheel 7 provides rolling support to the base 1 and the pumping unit body 2 installed on the base 1, allowing the base 1 and the pumping unit body 2 to move horizontally as a whole. This enables the pumping unit body 2 to be moved backward or reset relative to the wellhead, facilitating wellhead maintenance or restoration of pumping conditions. The entire process does not require disassembling the pumping unit body 2, improving relocation efficiency and operational safety.

[0020] like Figures 2 to 5As shown, the relocation assembly includes a second sliding plate 9 slidably mounted on one side of the base 1, a first sliding plate 5 fixedly mounted on one side of the second sliding plate 9, two connecting plates 8 symmetrically fixedly mounted on the first sliding plate 5, a hydraulic cylinder 6 rotatably mounted between the connecting plates 8, support plates 12 fixedly mounted on the symmetrical sides of the second sliding plate 9, and a transfer wheel 7 slidably mounted between the two support plates 12. The output end of the hydraulic cylinder 6 is connected to the transfer wheel 7. A sliding plate 10 is fixedly mounted on the support plate 12. A first sliding groove 3 and a second sliding groove 4 are provided on one side of the base 1. The sliding plate 10 is slidably mounted in the second sliding groove 4, and the second sliding plate 9 is slidably mounted in the first sliding groove 3. A first sliding groove 13 is provided on the support plate 12. A connecting column 14 is mounted on the output end of the hydraulic cylinder 6. The connecting column 14 is slidably installed in the first sliding groove 13, and a first mating plate 18 is fixedly installed on one side of the connecting column 14; a limiting groove 20 is opened on one side of the inner side of the second sliding plate 9, and a plurality of return springs 21 are fixedly installed in the limiting groove 20. The other ends of the plurality of return springs 21 are jointly installed with a receiving plate 16, and a second mating plate 19 is fixedly installed on one side of the receiving plate 16. One side of the second mating plate 19 is adapted to one side of the first mating plate 18; a through opening 17 is opened on the support plate 12, and the through opening 17 penetrates the first sliding groove 13. The receiving plate 16 is adapted to the through opening 17; mating seats 11 are fixedly installed on the symmetrical sides of the support plate 12, and a second sliding groove 15 is opened in the mating seat 11. The receiving plate 16 is slidably installed in the second sliding groove 15. When the belt-driven pumping unit relocation device needs to be moved, it first lifts the pumping unit body 2 with a jack, temporarily removing its weight from the base 1 to facilitate movement. Then, a control command is issued to activate the hydraulic cylinder 6. The hydraulic cylinder 6 drives the connecting column 14 outward through its output end. Constrained by the first sliding groove 13, the connecting column 14 can only slide along a set trajectory. As the connecting column 14 continues to move, it drives the connected transfer wheel 7 to move. Initially, the transfer wheel 7 slides horizontally within the first sliding groove 13. When it reaches the area of ​​the second sliding groove 15 between the support plates 12, its direction of movement changes from horizontal to vertical due to structural guidance, thus achieving the "flipping and unfolding" process of the transfer wheel 7. At this point, the transfer wheel 7 changes from its original retracted state to a supporting state, gradually supporting the weight of the pumping unit body 2, completing the unfolding of the roller assembly. As the hydraulic cylinder 6 further moves, it pushes the transfer wheel 7 forward, and the first mating plate 18 connected to the output end of the hydraulic cylinder 6 gradually engages with the first mating plate 18 installed on the support plate 12. The second mating plate 19 on plate 16 contacts and engages with the first mating plate 18 during the engagement process. During this process, the first mating plate 18 moves along the second mating plate 19, causing the transfer wheel 7 to gradually enter the area of ​​the second sliding groove 15. At the same time, the multiple return springs 21 set in the compression limit groove 20 store elastic energy during the contact between the first mating plate 18 and the second mating plate 19. When the transfer wheel 7 is fully entered into the area of ​​the second sliding groove 15, the elastic energy of the return springs 21 is released, causing the transfer wheel 7 to be further pushed out and stably extended, thus realizing the stable support and movable state of the pumping unit body 2, and finally completing the preparation for the relocation. Throughout the process, the sliding plate 10 moves in the second sliding groove 4 set on the side of the base 1, and the second sliding plate 9 slides in the first sliding groove 3, ensuring the overall stability and precise guidance of the structure. The sliding guide rail structure formed by the mating seat 11 and the support plate 12, as well as the through structure between the through port 17 and the first sliding groove 13, together ensure the coordination and repeatability of each component during the movement process, further improving the reliability of the device and the efficiency of the relocation.
