Description

Technical Field

[0001] This utility model relates to the field of well oil hydrant transportation technology, specifically a fixed structure for transporting well oil hydrants. Background Technology

[0002] An in-well refueling plug is a device used for aircraft refueling. It is typically installed in an in-well on the tarmac to facilitate refueling during takeoff and landing. The plug consists of a cylindrical device and an interface for connecting the fuel line. When an aircraft needs refueling, the refueling truck connects the on-board well connector to the plug and then supplies fuel to the aircraft. This process enables fast, safe, and efficient refueling, ensuring that the aircraft can complete refueling in a short time and is ready to continue flying. In-well refueling plugs play a vital role in air transport, guaranteeing the fuel supply to aircraft and ensuring the normal operation of flights.

[0003] However, during the actual installation of the aforementioned well refueling plugs, due to their heavy weight and lack of dedicated refueling plug transport tools, the handling process is prone to causing personnel injuries and requires more manpower. In view of this, we propose a fixing structure for transporting well refueling plugs. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing structure for transporting oil well filler plugs, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixed structure for transporting well oil hydrants, comprising a trolley, a crossbar fixedly connected to the top of the trolley, and a fixing component provided on the bottom end face of the crossbar, the fixing component comprising:

[0006] A fixed pulley is fixedly connected to the bottom end face of the crossbeam, and a take-up roller is rotatably connected to the inner wall of the trolley. A connecting rope is wound around the side wall of the take-up roller.

[0007] A crossbar is fixedly connected to the end face of the connecting rope, and a groove is provided at the bottom of the crossbar, which is slidably connected to the turntable.

[0008] A connecting frame is rotatably connected to the bottom end face of the turntable. A horizontal plate is fixedly connected to the side wall of the connecting frame, and a claw is provided at the bottom of the connecting frame.

[0009] Preferably, the number of connecting frames is set to four sets, and the four sets of connecting frames are hinged to each other in pairs.

[0010] Preferably, the top of the claw is threaded with a bolt, which is rotatably connected to the connecting frame.

[0011] Preferably, the connecting rope is movably connected to the side wall of the fixed pulley, and the take-up roller is located on one side of the fixed pulley.

[0012] Preferably, a rotating rod is fixedly connected to the side wall of the take-up roller. The rotating rod is sleeved with the trolley, so that the rotating rod rotates and drives the take-up roller to rotate, thereby winding up the connecting rope and raising the oil plug.

[0013] Preferably, the side wall of the trolley is provided with a transverse groove, which is slidably connected to a limiting rod. The limiting rod is movably connected to a rotating rod. Sliding the limiting rod to the left causes it to abut against the rotating rod, thereby preventing accidental rotation of the rotating rod.

[0014] Compared with the prior art, this utility model provides a fixing structure for transporting oil filling plugs in wells, which has the following beneficial effects:

[0015] 1. The fixed structure for transporting the well oil hydrant uses claws, crossbars, and sliding grooves. Pushing and pulling the crossbars, rotating the turntable, and connecting frame allow the claws to engage with the crossbars. The connecting frame is eccentrically positioned, allowing for small displacements during rotation. This ensures the claws more precisely align with the flanges on the oil hydrant, improving the fixing effect and preventing loosening or misalignment. Claws can be added or removed from the sliding groove via circular grooves, or their distribution can be adjusted to firmly grip flanges of different specifications.

[0016] 2. The fixed structure for transporting the well oil plug is designed with bolts. By rotating the bolts, the height between the jaws and the horizontal plate can be adjusted to accommodate oil plugs of different specifications. This avoids the risk of loosening and slippage due to height mismatch between the jaws and the flange, ensuring that the jaws can firmly clamp the flange without loosening or insufficient clamping force due to thickness differences.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a fixed structure for transporting well oil hydrants, including a trolley 1, a crossbeam 2 fixedly connected to the top of the trolley 1, and a fixing component 3 provided on the bottom end face of the crossbeam 2. The fixing component 3 includes a fixed pulley 301, a winding roller 302, a connecting rope 303, a crossbar 304, a chute 305, a turntable 306, a connecting frame 307, a cross plate 308, and a claw 309.

[0023] In one embodiment of this utility model, a fixed pulley 301 is fixedly connected to the bottom end face of a crossbeam 2, a take-up roller 302 is rotatably connected to the inner wall of a trolley 1, a connecting rope 303 is wound around the side wall of the take-up roller 302, the connecting rope 303 is movably connected to the side wall of the fixed pulley 301, the take-up roller 302 is located on one side of the fixed pulley 301, a rotating rod 4 is fixedly connected to the side wall of the take-up roller 302, the rotating rod 4 is sleeved with the trolley 1, so that the rotating rod 4 rotates and drives the take-up roller 302 to rotate, thereby winding the connecting rope 303 and lifting the oil plug. A horizontal groove 5 is opened on the side wall of the trolley 1, the horizontal groove 5 is slidably connected to a limiting rod 6, and the limiting rod 6 is movably connected to the rotating rod 4. Sliding the limiting rod 6 to the left causes the limiting rod 6 to abut against the rotating rod 4, thereby preventing the rotating rod 4 from rotating accidentally.

[0024] The crossbar 304 is fixedly connected to the end face of the connecting rope 303. There are four sets of connecting frames 307, and the four sets of connecting frames 307 are hinged to each other in pairs. The bottom of the crossbar 304 is provided with a sliding groove 305, which is slidably connected to the turntable 306. The connecting frame 307 is rotatably connected to the bottom end face of the turntable 306. The side wall of the connecting frame 307 is fixedly connected with a horizontal plate 308, and the bottom of the connecting frame 307 is provided with a claw 309.

[0025] Pushing and pulling the crossbar 304, rotating the turntable 306, and connecting frame 307 cause the claw 309 to engage with the horizontal plate 308 to fix the flange on the fuel filler plug. The rotation of the rotating rod 4 drives the winding roller 302 to rotate, winding the connecting rope 303 and lifting the fuel filler plug, thus allowing the fuel filler plug to be moved. The connecting frame 307 is eccentrically set, allowing for small displacement during the rotation of the connecting frame 307, so that the claw 309 can more accurately align with the flange on the fuel filler plug, thereby improving the fixing effect and preventing loosening or misalignment.

[0026] The slide 305 has circular grooves on both sides, through which claws 309 can be added or removed. Different well oil plugs have different flange diameters and the number of fixing holes. By adding or removing the number of claws 309, the distribution position of the claws 309 can be flexibly adjusted so that they can firmly grip flanges of different specifications, improving the versatility of the device. If some claws 309 need to be replaced due to wear or damage, they can be easily disassembled and replaced through the circular grooves, thereby reducing maintenance costs and time.

[0027] In addition, the top of the jaw 309 is threaded with a bolt 7, which is rotatably connected to the connecting bracket 307. By rotating the bolt 7, the height between the jaw 309 and the horizontal plate 308 can be adjusted to accommodate different sizes of oil plugs. This avoids the risk of loosening and slippage due to height mismatch between the jaw 309 and the flange, and ensures that the jaw 309 can firmly clamp the flange without loosening or insufficient clamping force due to thickness differences.

[0028] In this utility model, when in use, the push-pull crossbar 304, the rotating turntable 306, and the connecting frame 307 make the claw 309 cooperate with the cross plate 308, so that the rotating rod 4 rotates and drives the winding roller 302 to rotate, thereby winding the connecting rope 303 and lifting the refueling plug. At this time, the push vehicle can move the well refueling plug.

[0029] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
