The pressing block 37 interacts with the limiting block 41, one end of the limiting block 41 is embedded into a corresponding limiting groove B47 on the sliding rod 45 and interacts with the shaft A50, under the action of the limiting block 41, the rotation of the shaft A50 relative to the sliding rod 45 is limited, and the limiting block 41 compresses and stores energy to the spring C43 through the pressure spring ring B42.

When the invention is used for assisting a ground stayguy operator to pull a wire, the threaded sleeves 6 on the two telescopic rod structures 4 are firstly rotated, the threaded sleeves 6 rotate relative to the corresponding support rod B57, the threaded sleeves 6 drive the corresponding screw rods 5 to approach the support rod B57, and the two telescopic rod structures 4 are gradually shortened so that the invention can be placed in a vertical shaft of the cable well 1. The invention is then placed in the shaft of the wireline well 1 such that the guide ring 11 with the roller a15 is located just above the wellhead of the wireline well 1 and the roller B56 is located at the inner corner of the wireline well 1. And then reversely rotating the two thread sleeves 6 in the two telescopic rod structures 4 to extend the two telescopic rod structures 4. When the two telescopic rod structures 4 drive the four arc plates 10 to meet the well wall through the two support rods A3 and the four support legs 9, the threaded sleeve 6 is continuously rotated, so that the four arc plates 10 are tightly pressed against the well wall to fix the cable well 1 in the vertical shaft. After the invention is fixed, the screw sleeve 6 is stopped rotating.

The orientation of the roller A15 and the roller B56 is adjusted according to the pulling direction of the cable 2 at the cable pulling personnel at the bottom of the cable well 1 and above the well head, and the adjustment flow of the roller A15 is as follows:

and rotating the bolt A13 to release the fixation of the relative position of the sliding sleeve 12 and the guide ring 11, sliding the sliding sleeve 12 on the guide ring 11, making the rotating shaft of the roller A15 perpendicular to the direction of pulling the cable 2 by the ground cable puller, after the position adjustment of the roller A15 is finished, reversely rotating the bolt A13 to fix the relative position of the sliding sleeve 12 and the guide ring 11, and finishing the position adjustment of the sliding sleeve 12 on the guide ring 11.

Following adjustment of the particular orientation of roller B56 within wireline well 1, the adjustment of the orientation of roller B56 proceeds as follows:

firstly, bolt B44 is rotated to gradually release the pressing of bolt B44 on pressure lever B38, under the reset action of spring B40, pressure lever A36 drives pressing block 37 and pressure lever B38 to synchronously and vertically move in opposite directions, pressure lever A36 gradually releases the pressing on corresponding limiting plate 25, pressure lever B38 gradually releases the pressing on corresponding limiting plate 25, pressing block 37 gradually releases the limitation of limiting block 41, limiting block 41 gradually breaks away from the limiting groove on sliding rod 45 and gradually releases the relative fixing position of sliding rod 45 and sliding seat 27 and the rotation limitation of shaft A50 relative to sliding rod 45. The limit plates 25 in the guide rods 21 are gradually disengaged from the limit grooves on the respective two guide rails 19 by the respective two pre-compressed springs a 26. When the bolt B44 rotates for a certain number of turns, the pressing rod A36 and the pressing rod B38 completely release the pressing on the corresponding limit plate 25, the limit of the limit block 41 is completely released by the press block 37, the inclined plane on the press block 37 contacts with the inclined plane at one end of the limit block 41, and one end of the limit block 41 is completely separated from the limit groove on the slide rod 45. Spring B40 and spring A26 remain in a compressed energy storage state.

The sliding rod 45 is manually moved, so that the sliding rod 45 vertically slides in a sliding groove E29 in the sliding seat 27, and the sliding rod 45 drives a roller B56 to synchronously move through a transmission shell 48 and a shaft sleeve 49. When the roller B56 reaches the appropriate height in the uphole range at the inner corner of the wireline well 1, the action on the slide bar 45 is removed.

Then, while one hand is holding the slide bar 45 and temporarily fixing the relative position between the slide bar 45 and the slide carriage 27, the other hand is used to act on the slide carriage 27, and the slide carriage 27 is pushed by hand to move horizontally in the support frame 18 because the relative position restriction between the two guide rods 21 and the corresponding two guide rails 19 is released. During the movement of the slide 27, a mutual sliding between the slide 27 and the two guide rods 21 occurs. When one of the guide rods 21 slides relative to the slide carriage 27, the other guide rod 21 is moved synchronously with the slide carriage 27 along the respective two guide rails 19 by the slide carriage 27. The slide 27 moves synchronously with the slide 45 while the slide 27 moves horizontally in the support frame 18. When the slide rod 45 drives the roller B56 to the position of the downhole cable 2 through the transmission shell 48 and the shaft sleeve 49, the action on the slide carriage 27 is removed.

The twisting wheel 51 is then turned with one hand depending on the direction in which the cable 2 is pulled by the person pulling the cable 2 at the surface and the position in which the part of the cable 2 in the cable well 1 interacts with a corner in the cable well 1 due to the pulling of the person being pulled, while the other hand still temporarily fixes the relative position of the slide 45 and the slide 27. The torsion wheel 51 drives the shaft A50 to rotate, the shaft A50 drives the shaft B54 to rotate through the bevel gear A52 and the bevel gear B53, the shaft B54 drives the roller B56 to synchronously rotate around the central axis of the shaft B54 through the support B55, so that the roller B56 can effectively support the cable 2 in the cable well 1, the situation that the part of the cable 2 in the cable well 1 is separated from the contact friction between the roller B56 and a well wall due to the change of the ground bracing wire direction is avoided, the roller A15 and the roller B56 in the invention can still effectively support the pulled cable 2 under the condition that the ground bracing wire direction is changed, and the laying efficiency of the cable 2 is continuously improved through the rolling friction.

When the roller B56 rotates to a proper angle around the central axis of the shaft B54, the bolt B44 is rotated reversely, the bolt B44 gradually presses the pressing rod B38 downwards, the lower end of the pressing rod B38 gradually approaches the corresponding limiting plate 25, and meanwhile, the pressing rod B38 drives the pressing rod A36 and the pressing block 37 to move synchronously. The lower end of the pressure lever A36 gradually approaches the corresponding limit plate 25, the inclined surface of the pressure block 37 interacts with the inclined surface of the limit block 41, and the limit block 41 gradually slides towards the corresponding limit groove on the slide bar 45. The pressure rod A36 further compresses the spring B40 through the pressure spring ring A39 to store energy, and the limited block 41 further compresses the spring C43 through the pressure spring ring B42 to store energy.

When the pressure lever A36 meets the corresponding limit plate 25, the pressure lever B38 also just meets the corresponding limit plate 25, and one end of the limit block 41 enters the corresponding limit groove. As the bolt B44 continues to be rotated, the pressing rod a36 drives the corresponding limit plate 25 to move vertically downward in the corresponding sliding groove B23, and the limit plate 25 further compresses the corresponding two springs a26 again. The pressing rod B38 drives the corresponding limit plate 25 to vertically move downwards in the corresponding sliding groove B23, and the limit plate 25 further compresses the corresponding two springs A26 again. When the limit plates 25 in the two guide rods 21 enter the limit grooves a20 on the two corresponding guide rails 19, the limit block 41 reaches the limit position in the limit groove B47 and abuts against the shaft a50, and the limit block 41 limits the rotation of the shaft a50 relative to the sliding rod 45, and further limits the rotation of the shaft B54 relative to the shaft sleeve 49. The stop blocks 41 simultaneously re-fix the relative position between the slide 45 and the slide 27, the relative position between each guide bar 21 and the respective two guide rails 19 being re-limited by the interaction between the respective limit plate 25 and the guide rail 19.

Turning of bolt B44 is then stopped, and the orientation of roller B56 within cable well 1 is completely fixed, thereby completing the adjustment of the orientation of roller B56.

After the adjustment of the roller B56 is finished, the cable 2 is wound on the roller B56 and the roller a15 in sequence, so that the roller a15 and the roller B56 form actual support for the cable 2 forming the Z shape.

When the laying of the cable 2 is finished, the two screw sleeves 6 in the two telescopic rod structures 4 are simultaneously rotated, so that the two telescopic rod structures 4 are contracted, the four arc plates 10 release the conflict with the well wall, and the cable well 1 can be taken out.

In conclusion, the beneficial effects of the invention are as follows: according to the invention, the cable 2 supported and guided by the roller B56 and the roller A15 in sequence is supported away from the well edge of the cable well 1 by adjusting the position of the roller A15 at the shaft outlet of the cable well 1 and the position of the roller B56 at the corner of the cable well 1, so that the damage to the surface of the cable 2 caused by the friction of the cable 2 at the corner of the cable 2 well in the traditional cable 2 construction mode is avoided, and the construction quality of the cable 2 and the operation safety of the cable 2 after the cable 2 is constructed are ensured.

In addition, compared with the published special bracket for inserting the cable 2 in the municipal engineering with the publication number of '103956692A', the invention adapts to the condition that a cable pulling person pulls the cable at a wellhead along the direction inconsistent with the running direction of the underground cable according to the actual road surface condition on the ground by adjusting the position of the roller A15 on the guide ring 11 and the rotating angle of the roller B56 around the central axis of the shaft B54, ensures that the cable is still supported by the roller A15 and the roller B56 to smoothly carry out laying construction operation when the pulling direction of the ground cable pulling person is inconsistent with the running square of the underground cable, effectively avoids the cable from being separated from the roller A15 and the roller B56 due to the change of the pulling direction, the cable is guaranteed to be supported and guided by the roller A15 and the roller B56 under the condition that the direction of the cable pulling on the ground is changed, and the cable is not damaged by friction with the well edge of the cable well 1 and the corner of the cable well 1 due to the fact that the cable is separated from the roller A15 and the roller B56. Therefore, the cable laying efficiency is improved, and the safety of the cable after construction in the actual operation process is ensured.
