Description

Technical Field

[0001] This utility model relates to the field of logging instrument technology, and in particular to a line-raising device for an oil logging instrument. Background Technology

[0002] Existing logging tools mostly rely on multiple people working together to raise a steel wire rope to a certain height. U-shaped clips are used to secure the wire rope to the tensioner hooks, keeping it taut. Cable hooks are evenly distributed along the wire rope to hang gas lines, telephone lines, signal lines, power lines, etc., enabling the logging tool to be wired. Due to limitations in roof space and placement of the logging tool, the U-shaped clips need to be frequently repositioned, accelerating wire rope damage. Furthermore, the wire rope is generally long, making it very inconvenient for multiple people to work simultaneously on the roof. Multiple people working together to raise the wire is time-consuming, labor-intensive, and poses significant safety hazards. This paper proposes a wire raising device for oil logging tools.

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] Please see Figures 1 to 4This utility model provides a wire rope raising device for an oil logging tool, including a mounting box 1, a drum 5, and a drive assembly 3. The drum 5 is detachably installed inside the mounting box 1, which is mounted on the roof or other object of the logging tool to facilitate the raising of the wire rope used by the logging tool. The drum 5 is used to wind up or unwind the wire rope used by the logging tool. During the use of the logging tool, the wire rope needs to be erected. Conventionally, this is done by multiple people working together to straighten the wire rope. Adjustments are needed manually if the wire rope is too loose or too tight. In this application, the tension of the wire rope can be adjusted simply by winding up or unwinding the drum, greatly reducing manpower. The drive assembly 3 is connected to the drum 5 and is mounted on the mounting box 1. The drive assembly 3 drives the drum 5 to rotate, thereby raising the wire rope of the logging tool. The raising of the wire rope is facilitated by the winding up or unwinding of the drum 5, making it convenient to erect the wire rope at a high position and tighten it. During the use of the logging instrument, the U-shaped rope clips on the wire rope often need to be repositioned. Conventional wire ropes require multiple people working together to erect them, and repeatedly adjusting the U-shaped clips is not only labor-intensive but also causes wear and tear on the wire rope. With this wire-lifting device, when adjusting the rope clips or changing the wire rope position is needed, simply unwind or rewind the wire rope. Once the taut wire rope becomes loose, rewinding completes the adjustment. After well completion, when dismantling the cable, first unwind the wire rope for easy cable retrieval, remove the hook, and then rewind the wire rope evenly onto drum 5 using the rope arranger.

[0028] To better implement this utility model, refer to Figure 1 , Figure 3 and Figure 4 In one embodiment, the drum 5 is detachably mounted between the mounting rod 2 and the drive rod 305 of the drive assembly 3. The mounting rod 2 is rotatably connected to the side wall of the mounting box 1, and the drive rod 305 is rotatably connected to the side wall of the mounting box 1. The drive rod 305 and the mounting rod 2 are symmetrically arranged. In this embodiment, the mounting rod 2 and the drum 5 are detachably connected, and the side wall of the mounting box 1 to which the mounting rod 2 is connected is detachable.

[0029] Multiple limiting blocks 8 are evenly arranged circumferentially on the mounting rod 2 and the drive rod 305, and the limiting blocks 8 are arranged along the length direction of the mounting rod 2 and the drive rod 305. Each limiting block 8 on the mounting rod 2 and the drive rod 305 corresponds one-to-one with a limiting groove 501 on the inner wall of the drum 5. The limiting blocks 8 are elongated and arranged along the length direction of the mounting rod 2 and the drive rod 305, and are evenly distributed circumferentially on the mounting rod 2. At least two limiting blocks 8 are symmetrically arranged on the mounting rod 2 and the drive rod 305. In this embodiment, it is preferable to provide four circumferentially evenly arranged limiting blocks 8 on each of the mounting rod 2 and the drive rod 305. Similarly, four corresponding limiting grooves 501 are also provided on the inner wall of the drum 5, corresponding one-to-one with the limiting blocks 8.

[0030] Different wire rope lengths and diameters require different drum diameters. To ensure the wire lifting device can accommodate different wire ropes, the drum 5 is detachable. To facilitate this detachment, the side wall of the mounting box 1 connected to the mounting rod 2 is removable. This side wall is integrally connected to the mounting box 1 via a fixing assembly. When the drum 5 needs to be replaced, the side wall of the mounting box 1 is removed, and the side wall, along with the connected mounting rod 2, detaches from the inside of the drum 5, allowing the drum 5 to be separated from the other mounting rod 2.

[0031] like Figure 3 As shown, when installing the drum 5, the limiting groove 501 on the inner wall of the drum 5 is first aligned with the limiting block 8 on the drive rod 305, so that the drive rod 305 is inserted into the center of the drum 5. Then, the limiting block 8 on the disassembled mounting rod 2 is aligned with the limiting groove 501 and installed. Subsequently, the side wall disassembled from the mounting box 1 is fixedly connected to the entire mounting box 1, and the drum 5 is then installed. The total length of the mounting rod 2 and the drive rod 305 is less than or equal to the internal length of the mounting box 1. Through the cooperation of the limiting block 8 and the limiting groove 501, the drum 5 can be accurately installed, and the drive assembly 3 can smoothly drive the drum 5 to rotate.

[0032] To prevent the drum 5 from sliding left and right on the mounting rod 2 and the drive rod 305, multiple fixing grooves 6 are provided on the circumferential direction of the mounting rod 2 and the circumferential direction of the drive rod 305. The fixing grooves 6 are set along the length direction of the mounting rod 2 and the length direction of the drive rod 305, and the fixing grooves 6 are connected to the two ends of the drum 5 through connecting components. In this embodiment, four fixing slots 6 are provided and are evenly distributed around the mounting rod 2 and the drive rod 305. The connecting assembly includes L-shaped connectors and multiple bolts. Multiple screw holes are provided at both ends of the fixing slots 6 and the drum 5. After the drum 5 is positioned on the mounting rod 2 and the drive rod 305, since the two end faces of the fixing slots 6 and the drum 5 are perpendicular during installation, L-shaped connectors are provided at both ends of the fixing slots 6 and the drum 5. The horizontal part of the L-shaped connector is close to the fixing slot 6, and the vertical part of the L-shaped connector is close to the end face of the drum 5. The screw holes on the L-shaped connectors are aligned with the screw holes at both ends of the fixing slots 6 and the drum 5. Bolts are installed in the screw holes to fix the L-shaped connectors, thereby fixing the positions of the mounting rod 2, the drive rod 305 and the drum 5.

[0033] To better implement this utility model, refer to Figure 1 In one embodiment, the drive assembly 3 includes a worm gear 301 and a worm 302. The worm gear 301 is sleeved on the drive rod 305, and the worm 302 is rotatably mounted on the mounting box 1. One end of the worm 302 passes through the mounting box 1 and is connected to the handle 304 via a connecting rod 303. The worm gear 301 meshes with the worm 302. The handle 304 drives the worm 302 to rotate via the connecting rod 303, which in turn drives the worm gear 301 to rotate. The worm gear 301 then drives the drive rod 305 to rotate, thereby rotating the drum 5 to achieve the winding or unwinding of the wire rope of the logging instrument.

[0034] To better implement this utility model, refer to Figure 2 In one embodiment, a limiting component 4 is further included. The limiting component 4 is mounted on the mounting box 1 and connected to the drive component 3. The limiting component 4 is used to lock the drum 5, thereby effectively preventing the drum 5 from rotating unexpectedly in the reverse direction. The limiting component 4 includes a first gear 401, a second gear 402, and multiple sets of locking components. The center of the first gear 401 is connected to one end of the drive rod 305 after it passes through the side wall of the mounting box 1. The second gear 402 is mounted on the outer wall of the mounting box 1, and the first gear 401 and the second gear 402 mesh. Multiple sets of locking components are mounted on the side wall of the mounting box 1. The locking components are used to lock the second gear 402. After the second gear 402 is locked, the first gear 401 will also be unable to rotate, thereby preventing the connected drive rod 305 and the drum 5 from rotating.

[0035] In this embodiment, two sets of locking components are provided, and the locking components are symmetrically arranged with respect to the second gear 402. Each set of locking components includes a limiting rod 403 and multiple fixing plates 404. The multiple fixing plates 404 of each set of locking components are installed on the side wall of the mounting box 1 where the second gear 402 is installed, and the multiple fixing plates 404 are parallel to each other. The limiting rod 403 passes through the multiple fixing plates 404. The portion of the limiting rod 403 near the second gear 402 is fitted with a baffle 408 and an elastic member 405. One end of the elastic member 405 is connected to the baffle 408, and the other end is connected to the fixing plate 404 near the second gear 402. The end of the limiting rod 403 away from the second gear 402 is provided with a first small hole 406, and the side wall of the mounting box 1 is provided with a second small hole 407. The first small hole 406 and the second small hole 407 can be aligned, and an insert is provided after the first small hole 406 and the second small hole 407 are aligned. In this embodiment, the fixing plate 404 is used to limit the extension and retraction direction of the limiting rod 403, so that the limiting rod 403 extends and retracts perpendicular to the tooth groove of the second gear 402. Each locking assembly preferably has two fixing plates 404. When the drum 5 rotates, the limiting rod 403 moves towards the second small hole 407, so that the first small hole 406 and the second small hole 407 are aligned. The insert is inserted into the aligned first small hole 406 and second small hole 407. At this time, the end of the limiting rod 403 near the second gear 402 disengages from the tooth groove of the second gear 402, the elastic element 405 is in a compressed state, and the second gear 402 can rotate. Thus, when the driving assembly 3 drives the drum 5 to rotate, the driving rod 305 can drive the first gear 401 to rotate. After the drum 5 has finished winding or unwinding the wire rope, it is necessary to limit the position of the drum 5 to prevent it from rotating. At this time, the inserts in the first small hole 406 and the second small hole 407 are removed. Under the elastic force of the elastic element 405, the elastic element 405 causes the baffle 408 to move towards the second gear 402. The movement of the baffle 408 causes one end of the limiting rod 403 to move towards the tooth groove of the second gear 402. The two limiting rods 403 extend into the tooth groove of the second gear 402, thereby locking the second gear 402. The second gear 402 cannot rotate, and the first gear 401 meshing with the second gear 402 will also be unable to rotate, thereby locking the drive rod 305 and the drum 5.

[0036] The limiting component 4 can also be a two-way ratchet assembly. This assembly is installed inside the mounting box 1. The ratchet in the two-way ratchet assembly is connected to the worm 302 via gear or chain drive. The pawl in the two-way ratchet assembly is hinged to the ratchet seat, ensuring that the pawl can smoothly engage or disengage from the ratchet teeth. When locking the worm 302, the pawl, controlled by a locking and releasing mechanism, engages with the ratchet teeth. The engagement position of the pawl usually corresponds to the rotation direction of the worm 302, ensuring that the ratchet is effectively locked by the pawl when the worm 302 attempts to rotate. When unlocking the worm 302, the locking and releasing mechanism controls the pawl to disengage from the ratchet. Thus, locking and releasing the worm 302 controls the worm 302, in conjunction with the worm wheel 301 and the drive rod 305, to rotate or lock the drum 5.

[0037] To better implement this utility model, refer to Figure 1 In one embodiment, the system further includes a base 7, which is connected to the mounting box 1 via a universal joint. The universal joint enables the mounting box 1 to rotate, allowing it to be rotated to the optimal position for operation based on the actual site conditions.

[0038] To better implement this utility model, refer to Figure 1 In one embodiment, a rope guide is also included, which is installed on the side of the mounting box 1 where the wire rope is started. The rope guide is used to ensure that the wire rope is wound evenly on the drum 5, to ensure that the wire rope is tensioned during winding, and to guide the wire rope to be wound on the drum 5.

[0039] The working principle of the above-mentioned line-raising device for oil logging tools is as follows:

[0040] The direction of the mounting box 1 is adjusted by the universal joint. During the installation of the wire rope by the logging instrument, the first small hole 406 and the second small hole 407 are aligned, and inserts are inserted into the first small hole 406 and the second small hole 407, so that the limiting rod 403 is away from the tooth groove of the second gear 402. The operator turns the handle 304, which drives the worm gear 302 to rotate through the connecting rod 303. The worm gear 302 drives the worm wheel 301 to rotate, and the worm wheel 301 drives the drive rod 305 to rotate, thereby driving the drum 5 to rotate. To ensure that the drum 5 can rotate smoothly, the mounting rod 2 connected to the drum 5 also rotates. After the wire rope passes through the rope guide, The wire rope is wound onto the drum 5. The forward or reverse rotation of the drum 5 winds or unwinds the wire rope. After the wire rope is straightened, the drum 5 needs to be limited to prevent the wire rope from becoming loose. At this time, the insert block is pulled out, and under the elastic force of the elastic element 405, the baffle 408 moves towards the second gear 402, thereby driving the limiting rod 403 to extend into the tooth groove of the second gear 402. The limiting rod 403 locks the second gear 402. After the second gear 402 is locked, the corresponding first gear 401, drive rod 305 and drum 5 are all locked. At this time, the drum 5 cannot rotate, which keeps the wire rope taut.

[0041] When the drum 5 needs to be replaced, remove the connecting components installed on both ends of the fixing groove 6 and the drum 5, remove the side wall of the mounting box 1 connected to the mounting rod 2, and then remove the mounting rod 2 from the drum 5. The drum 5 can then be removed from the drive rod 305. When replacing the drum 5 again, align the limiting groove 501 on the replacement drum 5 with the limiting block 8 on the drive rod 305, and then insert the drive rod 305 into the drum 5. Align the limiting block 8 on the mounting rod 2 with the limiting groove 501, and then insert the mounting rod 2 into the drum 5. Then fix the side wall of the mounting box 1, and install the connecting components on both ends of the fixing groove 6 and the drum 5. The replacement of the drum 5 is thus completed.

[0042] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
