Embodiment Construction
[0020] The specific implementation modes and examples of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] A kind of fast loading and unloading cable clamp used in oil wells of the present invention, one of its specific implementation modes, as attached image 3 As shown, it includes a cable clamp arm 100, which is used to clamp and fix the cable on the outer wall of the oil well pipeline 350; as attached figure 2 shown, and includes at least one first movable shoe 110 and at least one second movable shoe 120 movably connected to the cable clamp arm 100, for fastening and hooping the oil well pipeline 350; at the same time, the first movable The shoe 110 and the second movable shoe 120 are provided with interlaced pin holes 113 and 123 , which are used to lock the buckled and hooped state through a detachable latch 130 . Because the oil well pipeline 350 is generally all longer, and the used cable clamps are also ...

The invention discloses a petroleum down-hole quickly-mounted and quickly-detached cable clamp, which comprises cable clamping arms, a first movable tile and a second movable tile, wherein the cable clamping arms are used for clamping and fixing a cable on the outer wall of a petroleum well pipe; the first movable tile and the second movable tile are movably connected with the cable clamping arms and are used for closing and fastening the petroleum well pipe; and the first movable tile and the second movable tile are provided with pin holes formed by alternate fit so as to be locked in the closing and fastening state by a detachable bolt. A technical scheme that the first and second movable tiles are movably connected with the cable clamping arms and are locked in a closing and fastening state by inserting the detachable bolt into the pin holes formed by alternate fit on the first and second movable tiles is adopted, so quick detachment requirements are met, a large amount of precious time is saved for petroleum well drilling operation, and particularly for offshore petroleum platforms, high petroleum drilling cost is reduced and obvious economic benefits are created.
Description
technical field [0001] The invention relates to the field of fixing devices for underground cables in petroleum wells. More specifically, the improvement relates to a cable clamp that can be quickly loaded and unloaded for underground petroleum wells. Background technique [0002] In the current oil well drilling operations, there are often cables that go deep down several kilometers along the casing or tubing. In order to avoid damage to very long cables, it is usually necessary to use a lot of cable clamps to hold the cables at intervals. The wire is clamped on the outer wall of the casing or tubing. [0003] However, traditional cable clamps generally use six or more screws for connection and fixing, which not only wastes a lot of precious time for installation, but also causes poor clamping reliability due to the diameter error of the casing or oil pipe . [0004] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0005] T...
