[0012] Figure 1 It is a schematic diagram of the overall structure of the auxiliary device for laying cables into a well in an embodiment of the present invention. Detailed Embodiments

[0013] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0014] As Figure 1 shown, it is the first embodiment of the auxiliary device for laying cables into a well of the present invention.

[0015] In this embodiment, the auxiliary device for laying cables into a well includes: two support frames 1 arranged opposite to each other; an optical axis 2 installed on the support frame 1; a roller shaft 3 sleeved on the optical axis 2, and the roller shaft 3 includes: a roller 31 sleeved on the optical axis 2 and two baffles 32 respectively connected to opposite ends of the roller 31. An accommodation cavity T is provided on the outer side where the baffle 32 is connected to the roller 31; a plurality of speed limiting components 4 installed in the accommodation cavity T, with one end of the speed limiting component 4 connected to the roller 31.

[0016] Wherein: The optical axis 2 drives the roller shaft 3 to rotate, raises the height of the cable to be lowered into the well through the roller shaft 3, and drives the cable to be lowered into the well that is advancing to move. The rollers 31 are respectively linked to a plurality of speed-limiting components 4, and the opposite ends of the speed-limiting components 4 swing to contact the optical axis 2 to increase friction so as to limit the rotation speed of the roller shaft 3.

[0017] During specific implementation, the support frame 1 is in the shape of a triangular plate. The optical axis 2 is connected at the top between the two support frames 1, and the stabilizing rod 5 is connected at the bottom between the two support frames 1. The function of the support frame 1 is to provide fixation and support in the whole device, used to support the cable to be lowered into the well, and the stabilizing rod 5 can enhance the stability of the auxiliary device for laying the cable into the well.

[0018] The roller shaft 3 is sleeved on the optical axis 2. The function of the optical axis 2 is to support the roller shaft 3, and at the same time support the pressure brought by the cable to be lowered into the well and support the rotation of the roller shaft 3 during use.

[0019] The roller shaft 3 is integrally cylindrical. The function of the roller shaft 3 is to raise the cable to keep it away from the ground to achieve the goal of avoiding friction, and at the same time can drive the cable to be lowered into the well forward by rolling, and complete the cable laying work more labor-saving.

[0020] Further, a receiving cavity T is provided on the outer side of the baffle 32 connected to the roller 31. In this embodiment, two receiving cavities T are provided, symmetrically arranged at the opposite ends of the roller 31 through which the optical axis 2 passes.

[0021] Further, the two baffles 32 at the opposite ends of the roller 31 are arranged symmetrically in structure. Four speed-limiting components 4 with the same structure are installed in the receiving cavity T of any one side baffle 32 of the roller shaft 3, and the positioning columns 41 of the four speed-limiting components 4 are evenly fixed on the roller 31.

[0022] In this embodiment, the function of the speed-limiting component 4 is to control the speed of the cable entering the well at a safe speed during use, and avoid equipment damage and personal injury caused by cable stall.

[0023] The plurality of speed-limiting components 4 include: a positioning column 41 connected to the roller 31 and a swing arm 42 swingably connected to the positioning column 41. An abutting surface 421 is provided on the swing arm 42. Wherein: increasing the centrifugal force received by the swing arm 42, the swing arm 42 swings relative to the positioning column 41, so that the abutting surface 421 on the swing arm 41 contacts and frictions with the optical axis 2.

[0024] During implementation, the positioning post 41 is successively connected to the roller 31, and the swing arm 42 is successively connected to the positioning post 41 and can swing relative to it. When the rotational speed of the roller shaft 3 is relatively low, the centrifugal force received by the speed limiting component 4 is relatively low, and the swing amplitude of the swing arm 42 relative to the positioning post 41 is limited. There is a contact surface 421 on the swing arm 42 that cannot come into contact and friction with the optical axis 2 to generate resistance. When the rotational speed of the roller shaft 3 is too fast, since the swing arm 42 is a Y-shaped plate, a counterweight 422 is provided at the other end opposite to the end of the swing arm 42 where the contact surface 421 is provided. When the centrifugal force received by the swing arm 42 increases, the swing amplitude of the swing arm 42 relative to the positioning post 41 increases significantly, thereby causing the contact surface 421 to come into contact and friction with the optical axis 2 to generate resistance, achieving the purpose of deceleration.

[0025] In the specific implementation of the auxiliary device for laying cables into a well in this embodiment, only need to place the auxiliary device for laying cables into a well at the wellhead, and then place the cable on the roller shaft 3. When pulling or pushing the cable into the well, the roller shaft 3 raises the height of the cable, and at the same time, the roller shaft 3 rolls to drive the cable to move forward, realizing avoiding the cable from rubbing against the ground and the wellhead and making it more labor-saving to push and pull the cable, improving the operation efficiency. During the operation process, the speed limiting component 4 can control the speed of the cable entering the well at a safe speed, avoiding equipment damage and personal injury caused by the cable stalling.
