Description

Technical Field

[0001] This invention relates to the field of oil well control equipment technology, and more particularly to an integrated oil well control cabinet. Background Technology

[0002] Oil well control cabinets are control devices used to ensure the safe production of oil wells. They are an important component of oil well safety production, offshore environmental protection, and oil well automation control. To facilitate the movement of oil well control cabinets, casters are usually installed at the bottom of the cabinets.

[0003] Because the surrounding surfaces of the oil wells are uneven, the existing oil well control cabinets, which use wheels at the bottom for movement, are not suitable for navigating such uneven surfaces, such as muddy, potholed, or steep terrain. The wheels experience high resistance and poor stability on these surfaces, and may even become stuck, severely limiting the range of applications for this control cabinet.

[0004] Therefore, the present invention provides an integrated oil well control cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated oil well control cabinet to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated oil well control cabinet includes a cabinet body. At the bottom of the cabinet body are symmetrically arranged tracked wheel combination walkers near both sides. Each tracked wheel combination walker includes a support plate, rollers, leather tracks, elastic polygonal spreaders, and tensioners. Two rollers, located at opposite ends, are connected to one side of the support plate. The elastic polygonal spreaders on the two rollers are connected via the leather tracks. These spreaders expand the leather tracks into partial polygons. The inflection points on the leather tracks located on one side of the rollers are radially close to the outer edge of the rollers. The tensioners are located in the middle of one side of the support plate and are used to tension the leather tracks.

[0008] As a further description of the above technical solution:

[0009] The elastic polygonal spreader includes a connecting shaft, a spreading wheel, and an elastic telescopic link. The connecting shaft is disposed through the surface of the roller and the two are rotatably connected. The number of connecting shafts is at least six and they are evenly distributed circumferentially. One end of the connecting shaft is connected to the spreading wheel through an outer arm plate, and the other end is fixedly connected to an inner arm plate. The free end of the inner arm plate is movably connected to the adjacent connecting shaft through the elastic telescopic link. The outer peripheral wall of the spreading wheel is provided with an annular limiting groove that contacts the leather track.

[0010] As a further description of the above technical solution:

[0011] The elastic polygonal spreader includes a connecting shaft, a spreading wheel, and an elastic telescopic link. The connecting shaft is disposed through the surface of the roller and the two are rotatably connected. The number of connecting shafts is at least six and they are evenly distributed circumferentially. One end of the connecting shaft is connected to the spreading wheel through an outer arm plate, and the other end is fixedly connected to an inner arm plate. The free end of the inner arm plate is movably connected to the adjacent connecting shaft through the elastic telescopic link. The outer peripheral wall of the spreading wheel is provided with an annular limiting groove that contacts the leather track.

[0012] As a further description of the above technical solution:

[0013] The elastic telescopic link includes an outer tube, an inner link, and a tension spring. One end of the inner link is hinged to the free end of the inner arm plate, and the other end is sleeved inside the outer tube. The tension spring is located inside the outer tube, and a hook that engages with the connecting shaft is fixedly connected to one side of the outer tube.

[0014] As a further description of the above technical solution:

[0015] The number of hooks is at least two and they are distributed along the length of the outer tube, and a pull rod is fixedly connected to one side of the outer tube.

[0016] As a further description of the above technical solution:

[0017] The tensioner includes a support arm, a pressure roller, a transmission rod, a lead screw, and a threaded sleeve. A vertical positioning sleeve that is rotatably connected to the lead screw is fixedly connected to the middle of one side of the bearing plate. The support arm located on both sides of the lead screw is rotatably connected to one side of the bearing plate. The pressure roller is rotatably connected to one end of the support arm and is in contact with the outer surface of the leather track. The threaded sleeve is screwed onto the lead screw and its outer wall is hinged to one side of the support arm on both sides of the lead screw through two transmission rods.

[0018] As a further description of the above technical solution:

[0019] A drive lever is fixedly connected to the bottom of the lead screw.

[0020] As a further description of the above technical solution:

[0021] One side of the outer arm plate is fixedly connected to a support shaft that is rotatably connected to the spreader wheel, and the outer periphery of the leather track is fixedly connected to a drag-increasing rubber strip evenly distributed around it.

[0022] As a further description of the above technical solution:

[0023] The outer circumference of the spreading wheel is fixedly provided with a resistance-increasing protrusion located in the annular limiting groove.

[0024] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0025] 1. In this invention, an elastic polygonal expander is set on one side of the roller, and a leather track is connected between the two elastic polygonal expanders. After the leather track is expanded by the elastic polygonal expander, it is located on one side of the roller. This arrangement enables the cabinet to have both rolling and track-assisted walking functions, and has the advantage of being suitable for walking on both flat and uneven surfaces.

[0026] 2. In this invention, the elastic polygonal expander expands the leather track into a partially deformable structure. This arrangement makes the friction between the leather track and the ground approximately zero when the roller travels on a flat road surface, thus not affecting the speed at which the cabinet travels on a flat road surface.

[0027] 3. In this invention, the elastic polygonal expander is provided with an elastic telescopic link. The elastic telescopic link has the function of adjusting the tension of the leather track, which has the advantage of enabling the cabinet to travel on roads with severe ravines and steep slopes.

[0028] 4. In this invention, a tensioner is provided, and a lead screw is provided on the tensioner. By controlling the rotation of the lead screw, the tension of the leather track can be easily adjusted. This has the advantages of quick, labor-saving, and convenient replacement, maintenance, and resetting of the leather track. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example 1

[0040] Please see Figure 1-4 An integrated oil well control cabinet includes a cabinet body 1, which houses control electrical components. At the bottom of the cabinet body 1, there are tracked wheel combination walkers 2 arranged symmetrically on both sides. These tracked wheel combination walkers 2 enable the cabinet body 1 to move stably and quickly on uneven roads, as well as on flat roads. In addition, they also reduce the pushing resistance of the cabinet body 1.

[0041] The tracked wheel combination walker 2 includes a support plate 21, rollers 22, leather tracks 23, elastic polygonal spreaders 24, and tensioners 25. The support plate 21 is fixedly connected to the bottom of the cabinet 1. Two rollers 22 are connected to one side of the support plate 21, which are located at both ends respectively. The rollers 22 contact the walking surface and support the entire control cabinet. Rubber rings are set on the outer periphery of the rollers 22. When the cabinet 1 is pushed, the rollers 22 roll, realizing the translation of the cabinet 1.

[0042] An elastic polygonal expander 24 is connected to one side of the roller 22. The elastic polygonal expanders 24 on the two rollers 22 are connected by the track 23. The elastic polygonal expander 24 has the function of expanding the track 23 into a partial polygon. The inflection point on the track 23 located on one side of the roller 22 is radially close to the outer edge of the roller 22. When the roller 22 is in contact with a flat walking surface, the outer wall of the track 23 will periodically contact the walking surface. At this time, the track 23 will not increase the resistance of the roller 22. When the roller 22 is in contact with an uneven walking surface, the outer wall of the track 23 will continuously contact the walking surface. At this time, with the assistance of the track 23, the rolling resistance of the roller 22 is greatly reduced, and the stability of the cabinet 1 is greatly improved.

[0043] A tensioner 25 is provided in the middle of one side of the bearing plate 21. The tensioner 25 has the function of tensioning the leather track 23.

[0044] Specifically, the elastic polygonal spreader 24 includes a connecting shaft 241, a spreading wheel 242, and an elastic telescopic link 243. The connecting shaft 241 is disposed through the disc surface of the roller 22 and the two are rotatably connected. The number of connecting shafts 241 is at least six and they are evenly distributed circumferentially. In this embodiment, the number of connecting shafts 241 is six. One end of the connecting shaft 241 is connected to the spreading wheel 242 through the outer arm plate 2411, and the other end is fixedly connected to the inner arm plate 2412. The free end of the inner arm plate 2412 is movably connected to the adjacent connecting shaft 241 through the elastic telescopic link 243. When the length of the elastic telescopic link 243 changes, the connecting shaft 241 will rotate. That is to say, the elastic telescopic link 243 provides tension to the spreading wheel 242 to spread the leather track 23.

[0045] Among them, an annular limiting groove 2421 is provided on the outer peripheral wall of the spreading wheel 242 to contact the track 23. The inner peripheral wall of the track and the outer peripheral wall of the annular limiting groove 2421 are in contact. This arrangement has the function of preventing the track 23 from being stuck in the groove. Moreover, due to the auxiliary lifting function of the track 23, it is convenient for the control cabinet to be turned on the spot on uneven roads to adjust the direction of the cabinet 1.

[0046] The aforementioned elastic telescopic link 243 includes an outer tube 2431, an inner link 2432, and a tension spring 2433. One end of the inner link 2432 is hinged to the free end of the inner arm plate 2412, and the other end is sleeved inside the outer tube 2431. The tension spring 2433 is located inside the outer tube 2431. A hook 24311 that engages with the connecting shaft 241 is fixedly connected to one side of the outer tube 2431. In other words, the outer tube 2431 and the connecting shaft 241 have the function of quick docking and disassembly. This arrangement facilitates the maintenance and replacement of the leather track 23, or facilitates reset when the leather track 23 is accidentally dislodged.

[0047] Example 2

[0048] Please see Figure 3 , Figure 4 and Figure 5 The difference from Embodiment 1 is that the number of hooks 24311 is at least two and they are distributed along the length of the outer sleeve 2431. When different hooks 24311 are replaced and connected to the connecting shaft 241, the elastic support force on the spreading wheel 242 is different. This setting has the function of adjusting the tension of the leather track 23, which is suitable for walking on roads with steep slopes. A pull rod 24312 is fixedly connected to one side of the outer sleeve 2431. This pull rod 24312 is a manually operated part. By manually pulling the pull rod 24312, different hooks 24311 and connecting shaft 241 can be replaced, and the switching operation is convenient.

[0049] In this embodiment, the tensioner 25 includes a support arm 251, a pressure roller 252, a transmission rod 253, a lead screw 254, and a threaded sleeve 255. A vertical positioning sleeve 211, which is rotatably connected to the lead screw 254, is fixedly connected to the middle of one side of the bearing plate 21. The support arm 251, located on both sides of the lead screw 254, is rotatably connected to one side of the bearing plate 21. A pressure roller 252 is rotatably connected to one end of the support arm 251. The pressure roller 252 is in contact with the outer surface of the leather track 23. The threaded sleeve 255... 5 is screwed onto the lead screw 254 and its outer wall is hinged to one side of the support arm 251 on both sides of the lead screw 254 through two transmission rods 253 respectively. The two pressure rollers 252 press down on the leather track 23 to achieve tensioning of the leather track 23. The lead screw 254 adjusts the downward pressure of the pressure rollers 252 through the screw sleeve 255 and the transmission rods 253. Conversely, it can quickly release the squeezing pressure on the leather track 23. This setting has the function of switching between different hooks 24311 with effortless operation.

[0050] The bottom of the lead screw 254 is fixedly connected to the drive lever 2541.

[0051] Example 3

[0052] Please see Figure 6 and Figure 7The difference from Embodiment 1 is that a support shaft 24111 is fixedly connected to one side of the outer arm plate 2411 and rotatably connected to the spreading wheel 242. A uniformly distributed friction-increasing rubber strip 231 is fixedly connected to the outer periphery of the track 23. The friction-increasing rubber strip 231 increases the friction force in contact with the ground. A friction-increasing protrusion 2422 is fixedly provided on the outer periphery of the spreading wheel 242 within the annular limiting groove 2421. This allows the track 23 to have the function of rotating relative to the roller 22. Simply put, when the roller 22 is stuck in the groove and the rolling resistance is high and it cannot move, the track 23 carries the entire control cabinet. When the cabinet 1 is pushed, the track 23 contacts the ground. Under the action of friction, the track 23 will easily rotate first, and then passively push the cabinet 1 to move, so that the roller 22 can quickly get out of the groove, which has the advantage of walking and getting out of trouble.

[0053] Working principle:

[0054] 1. Walking on potholed roads:

[0055] The load on the leather track 23 at the bottom of the cabinet 1 is greater than that on the roller 22. The bottom of the leather track 23 is in contact with the uneven road surface. When the cabinet 1 is pushed manually, the leather track 23 will rotate under the action of ground friction, which will drive the entire cabinet 1 to move smoothly with little resistance.

[0056] When turning on this road surface, the chassis 1 can be easily twisted to change the direction of travel because the track 23 is in surface contact with the ground.

[0057] 2. Walking on a smooth surface:

[0058] The roller 22 at the bottom of the cabinet 1 plays a role in bearing the weight. When the cabinet 1 is pushed, the friction between the leather track 23 and the ground is close to zero, so the cabinet 1 moves quickly and smoothly.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
