Description

Technical Field

[0001] The utility model relates to the technical field of sealed load-bearing detection cables, in particular to a sealed load-bearing detection cable capable of preventing extrusion deformation. Background Art

[0002] With the rapid development of cable logging technology and the advent of new logging instruments, the production technology of load-bearing detection cables used in conjunction with it has become increasingly perfect. This type of cable is used as a connecting line for hanging weight instruments for measurement. It is mainly used for logging, perforating, coring and other operations in various oil and gas wells. It can also be used in marine surveys, rivers, harbors, water conservancy, hydrological measurements, coalfield geological exploration, geothermal logging and other aspects.

[0003] Chinese patent announcement number CN108598805B discloses a sealed load-bearing detection cable that prevents extrusion deformation. By providing a clamping mechanism and a clamping mechanism, when it is necessary to dock two cables with each other, the joints of the two cables are placed on the semicircular sleeve on the second U-shaped fixing frame, and the rotating block is rotated. The rotating block drives the threaded rod to rotate in the sleeve and the rolling bearing, and the threaded rod pushes the pressure rod to move downward through the slide groove, and the pressure rod pushes one of the semicircular sleeves and the first U-shaped fixing frame to move downward. When the two semicircular sleeves are docked and clamped with each other, the fixed block at the bottom of the first U-shaped fixing frame extends into the groove at the top of the second U-shaped fixing frame, the fixed block squeezes the inner rod, the inner rod squeezes the second spring, and the second spring drives the inner rod to extend into the outer rod. When the clamping block is close to the through hole on the right side of the groove, the first spring pushes the clamping block to extend out of the through hole, clamps the first U-shaped fixing frame and the second U-shaped fixing frame, so that the two semicircular sleeves are pressed against each other, and the two cables can be clamped.

[0004] Since the above-mentioned load detection cable is protected by a semicircular cylinder, but no limiting structure is set on the outer wall of the cable, and since the second elastic telescopic rod is fixedly connected to the first support rod, when the wire body is bent, the second elastic telescopic rod cannot move with the bending of the wire body, so there are certain limitations.

[0011] Preferably, the outer wall of the shell is provided with a thread, and the inner wall of the connecting ring is adapted to the thread provided on the outer wall of the shell. When the connecting ring rotates, it moves under the action of the thread, and the outer wall of the connecting ring abuts against the outer wall of the resisting ring.

The operation is simple and convenient.

[0015] 2. The sealed load-bearing detection cable that prevents extrusion deformation is provided with a moving ring and a connecting ring. After the outer shell is pressed, the moving ring is moved by sliding, so that the moving ring drives the connecting ring to move through the spring telescopic rod 2 until the connecting ring contacts the outer shell. Since the inner wall of the connecting ring is adapted to the thread opened on the outer wall of the outer shell, when the moving ring rotates, the connecting ring will move to the outer wall of the outer shell under the action of the thread, thereby completing the fixation of the outer shell. Since the two ends of the spring telescopic rod 2 are respectively rotatably connected to the outer wall of the moving ring and the outer wall of the connecting ring, the spring telescopic rod 2 can swing on the outer wall of the moving ring and the outer wall of the connecting ring.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a sealed load-bearing detection cable that prevents extrusion deformation, including a cable body 1, the outer wall of the cable body 1 is fixedly connected to a limiting plate 101, the outer wall of the cable body 1 is provided with a limiting component 2, and the outer wall of the cable body 1 is provided with an auxiliary component 3.

[0022] The limiting component 2 includes a shell 201, an arc plate 202 and a spring telescopic rod 203. The shell 201 is arranged on the outside of the cable body 1. The outer wall of the shell 201 is fixedly connected with a butt ring. The outer wall of the shell 201 is provided with a thread. The arc plate 202 is installed on the outer wall of the cable body 1. The arc plates 202 are evenly distributed inside the shell 201. The shell 201 is distributed on both sides of the outer wall of the cable body 1. The outer wall of the arc plate 202 abuts against the outer wall of the limiting plate 101. The existence of the arc plate 202 can limit the connection between the cables. The spring telescopic rod 203 is arranged on the outer wall of the shell 201. One end of the spring telescopic rod 203 is fixedly connected to the outer wall of the shell 201. The end of the spring telescopic rod 203 away from the shell 201 is fixedly connected to the outer wall of the arc plate 202. The shell 201 can be pressed so that the shell 201 applies pressure to the arc plate 202 through the spring telescopic rod 203.

[0023] By setting the shell 201 and the arc plate 202, after the two cable bodies 1 are connected, the shell 201 can be moved so that the arc plate 202 is stuck on the outer wall of the cable body 1 and abuts against the outer wall of the limiting plate 101, thereby completing the limitation of the cable body 1. The shell 201 is continuously pressed so that the shell 201 applies pressure to the arc plate 202 through the spring telescopic rod 203 until the outer walls of the shell 201 contact each other, thereby completing the limitation between the cables. The operation is simple and convenient.

[0024] The auxiliary component 3 includes a movable ring 301, a connecting ring 302 and a spring telescopic rod 2 303. The movable ring 301 is installed on the outer wall of the cable body 1, and the inner wall of the movable ring 301 is slidably connected to the outer wall of the cable body 1. The movable ring 301 can move on the outer wall of the cable body 1. The connecting ring 302 is installed on the outer wall of the outer shell 201. The inner wall of the connecting ring 302 is adapted to the thread provided on the outer wall of the outer shell 201. When the connecting ring 302 rotates, it will move under the action of the thread. The outer wall of the connecting ring 302 abuts against the outer wall of the abutting ring. The existence of the abutting ring can limit the connecting ring 302. The spring telescopic rod 2 303 is arranged on the outside of the cable body 1. One end of the spring telescopic rod 2 303 is rotatably connected to the movable ring 301, and the end of the spring telescopic rod 2 303 away from the movable ring 301 is rotatably connected to the outer wall of the connecting ring 302. The movable ring 301 can drive the connecting ring 302 to move through the spring telescopic rod 2 303.

[0025] By setting the moving ring 301 and the connecting ring 302, after the outer shell 201 is pressed, the moving ring 301 is moved by sliding, so that the moving ring 301 drives the connecting ring 302 to move through the spring telescopic rod 2 303 until the connecting ring 302 contacts the outer shell 201. Since the inner wall of the connecting ring 302 is adapted to the thread opened on the outer wall of the outer shell 201, when the moving ring 301 rotates, the connecting ring 302 will move to the outer wall of the outer shell 201 under the action of the thread, thereby completing the fixation of the outer shell 201. Since the two ends of the spring telescopic rod 2 303 are rotatably connected to the outer wall of the moving ring 301 and the outer wall of the connecting ring 302 respectively, the spring telescopic rod 2 303 can swing on the outer wall of the moving ring 301 and the outer wall of the connecting ring 302.

[0026] When in use, the two cables are connected, and then the two shells 201 are moved so that the arc plate 202 contacts the outer wall of the cable. At this time, the outer wall of the arc plate 202 abuts against the outer wall of the limit plate 101, and the shell 201 is continuously moved until the outer walls of the two shells 201 abut against each other, and the movable ring 301 is moved by sliding, so that the movable ring 301 drives the connecting ring 302 to move through the spring telescopic rod 2 303 until one side of the connecting ring 302 contacts the outer wall of the shell 201, and the movable ring 301 is rotated so that the movable ring 301 drives the connecting ring 302 to rotate through the spring telescopic rod 2 303. At this time, the connecting ring 302 will be driven to move by the spring telescopic rod 2 303 under the action of the thread until the outer wall of the connecting ring 302 abuts against the outer wall of the abutting ring, thereby completing the fixation of the shell 201.
