Technical Field
[0001] This utility model belongs to the field of oilfield mobile equipment technology, and relates to a mobile device for well workover rigs. Background Technology
[0002] To improve the utilization rate of drilling platforms and equipment and reduce drilling costs, onshore cluster drilling has developed rapidly in recent years. Cluster well operations not only significantly save land area and reduce the time required for relocating and installing drilling equipment and the amount of pre-drilling work, but also reduce the amount of oil production and transportation metering stations, pipelines, and construction work, facilitating automated management. In China, cluster well operations can be achieved by moving drilling rigs or platforms while keeping the winch stationary. The drilling rope passes through the reel on the drilling rig and reaches the winch horizontally. By adjusting the length of the drilling rope in the horizontal section, cluster well operations can be achieved.
[0003] Chinese utility model CN219449243U, published on 2023-08-01, discloses a lifting operation platform for a well workover rig. It designs a fixed structure for the mobile platform. The principle is that the motor drives the threaded rod to rotate, which in turn drives the moving plate to move downward. Support rods are set at both ends of the moving plate and move downward to contact the ground. The moving platform is fixed by the friction between the support rods and the ground.
[0004] However, in existing devices, dirt adheres to the bottom of the support rod when it contacts the ground. When the support rod moves upward and retracts into the housing, the dirt falls into the housing and is difficult to clean. Therefore, a telescopic fixing structure was designed to avoid these problems. Utility Model Content
[0005] The purpose of this utility model is to provide a mobile device for well repair rigs, which has the advantages of preventing soil from entering the interior of the mobile platform when the device is fixed, making it easier to clean, and solving the problem of soil being difficult to clean inside the shell of existing devices.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0030] This utility model relates to a mobile well-servicing machine device, such as... Figure 1 As shown, the system includes a mobile platform 1, with a mounting base 4 at the top center for connection to a workover rig. A fixing component 2 is installed inside the mobile platform 1 to secure the mobile device carrying the workover rig to the ground. A cleaning component 3 is installed at the bottom of the mobile platform 1 for cleaning the soil at the bottom. Casters are installed at the four corners of the bottom of the mobile platform 1.
[0031] Specifically, the fixed component 2 is as follows: Figure 2 As shown, it includes a motor 21, which is fixed to the bottom of the mobile platform 1 and is connected to an external power source during use. The output shaft of the motor 21 is fixedly connected to a first gear 22.
[0032] It also includes support components 23, such as Figure 3 As shown, the support component 23 includes:
[0033] A rectangular shell 231 is fixedly attached to the bottom of the interior of the moving platform 1. It also includes a rectangular rod 232, which penetrates the bottom of the interior of the moving platform 1 and inserts into the interior of the rectangular shell 231, slidingly connecting with the inner wall of the shell 231. The rectangular rod 232 is hollow inside, and a threaded rod 234 is provided inside it. The threaded rod 234 penetrates the top of the rectangular shell 231 and the top of the rectangular rod 232; the threaded rod 234 is threadedly connected to the top of the rectangular rod 232 and rotatably connected to the top of the rectangular shell 231; a baffle 235 is provided at the bottom of the threaded rod 234. The baffle 235 is designed to prevent the threaded rod 234 from separating from the rectangular rod 232 when it rotates.
[0034] A second gear 236 is fixedly connected to one end of the threaded rod 234 extending from the rectangular shell 231. The second gear 236 meshes with the first gear 22. A base plate 233 is fixedly connected to the bottom end of the rectangular rod 232. The base plate 233 is a circular plate with a certain thickness. The center of one end face of the base plate 233 is fixedly connected to the rectangular rod 232. The base plate 233 is located at the bottom outer end of the moving platform 1. In use, when the rectangular rod 232 extends, the base plate 233 contacts the ground to form support. After the rectangular rod 232 retracts back into the moving platform, the base plate 233 returns to its original position at the bottom outer end of the moving platform 1. Four arc-shaped through slots 237 are provided on the edge of the base plate 233. Four protrusions 238 are provided in a position that matches the size and shape of the four arc-shaped through slots 237. The protrusions 238 are fixedly connected to the bottom outer end of the moving platform 1. The design of the through groove 237 and the protrusion 238 allows the protrusion 238 to insert into the through groove 237 when the base plate 233 moves upward, pushing the soil at the bottom of the base plate 233 away from the base plate 233. The through groove 237 is designed to be arc-shaped and there are 4 of them, which can maximize the separation of the soil at the bottom of the base plate 233 from the base plate 233.
[0035] As described above, four sets of support components 23 are evenly distributed around the periphery of the first gear 22. This four-set design increases the contact area with the ground, thereby enhancing friction and improving the restraint of the moving platform. The four sets of support components 23 work simultaneously to ensure the balanced ascent and descent of the moving platform 1.
[0036] To better clean the dirt from the base plate 233, this utility model also includes a cleaning component 3, such as... Figure 4 As shown, the cleaning component 3 includes a rotating rod 31, which is rotatably connected to the bottom of the mobile platform 1 and located at the center of the four base plates 233. A third gear 32 is fixedly sleeved on the rotating rod 31. A scraper 35 is fixedly connected to the bottom of the rotating rod 31. The scraper 35 has blade-shaped edges on both sides at the end away from the rotating rod 31. The blade-shaped design can better separate the base plates 233 from the soil.
[0037] A connecting block 33 is fixedly connected to the bottom of the mobile platform 1. A worm gear 34 is rotatably connected through the connecting block 33, and the worm gear 34 meshes with a third gear 32. A handle 36 is provided at the end of the worm gear 34 away from the third gear 32. The handle 36 is designed for easy gripping and control of the rotation of the worm gear 34.
[0038] Working principle of this utility model:
[0039] When the workover rig needs to be moved, first connect the mounting base 4 to the workover rig, then move the moving platform 1 to a suitable position. Connect the motor 21 to an external power source, driving the first gear 22 to rotate, which in turn drives the second gear 236 to rotate. The second gear 236 drives the threaded rod 234 to rotate. The rectangular rod 232 is threadedly connected to the threaded rod 234, while the rectangular shell 231 restricts the rotation of the rectangular rod 232. This drives the rectangular rod 232 to move downwards, causing the base plate 233 to contact the ground, thus supporting the moving platform 1 on the ground. The friction between the base plate 233 and the ground is used to limit the position of the moving platform 1.
[0040] When the workover rig needs to be moved again, the motor 21 is first reversed to drive the first gear 22, which in turn drives the second gear 236 to rotate. The second gear 236 drives the threaded rod 234 to rotate. The rectangular rod 232 is threadedly connected to the threaded rod 234. At the same time, the rectangular shell 231 restricts the rotation of the rectangular rod 232, thus driving the rectangular rod 232 to move upward. When the base plate 233 is retracted to the outer bottom of the moving platform 1, the protrusion 238 pushes out the soil in the through groove 237. At the same time, the worm gear 34 can be manually controlled to rotate, so that the worm gear 34 and the third gear 32 rotate, causing the rotating rod 31 to drive the scraper 35 to rotate. When the scraper 35 rotates, it contacts the soil at the bottom of the base plate 233 and scrapes off the soil at the bottom of the base plate 233.
