It should be noted that the first bearing plate 1, the second bearing plate 2 and the pull body 7 may be integrally formed or assembled. When the first bearing plate 1, the second bearing plate 2 and the pull body 7 are assembled, the first bearing plate 1 and the second bearing plate 2 can be connected with the first end 71 of the pull body 7 by welding, riveting or the like. The shape of the first bearing plate 1 can be the same as or different from that of the second bearing plate 2; the first bearing plate 1 may or may not be the same size as the second bearing plate 2. The distance between the first bearing plate 1 and the second bearing plate 2 may be set according to actual needs, as long as it is ensured that the vehicle-mounted guy rope can just pass through the space between the first bearing plate 1 and the second bearing plate 2, and the embodiment of the present invention is not particularly limited thereto.
In addition, the aperture of the first through hole, the aperture of the third through hole and the aperture of the fifth through hole can be slightly larger than the diameter of the first pin 5, as long as it is ensured that the first pin 5 can just pass through the first through hole, the fifth through hole and the third through hole.

Finally, the connection between the two ends of the balancing rail 9 and the two ends of the balancing bar 8 may be welding or the like. The connection between the portion between the first end 81 and the second end 82 of the balance bar 8 and the second end 72 of the pull body 7 may be welding, screwing, etc. When the index string is connected to the other portion of the pull body 7 except the first end 71 of the pull body 7, the index string may be wound around the sidewall of the pull body 7 and tied, or the index string may be connected to other portion of the pull body 7 except the first end 71 of the pull body 7 in other manners, which is not limited in the embodiments of the present invention.
It is worth noting that when the climbing assistance device provided by the embodiment of the invention is used, the vehicle-mounted guy rope can pass through the space between the first bearing plate 1 and the second bearing plate 2, the first pulley 3 and the second pulley 4 are both in contact with the vehicle-mounted guy rope, then, one end of the vehicle-mounted guy rope is connected with the top of the well frame, and the other end of the vehicle-mounted guy rope is connected with the workover vehicle. One end of the index rope is connected to the other part of the pulling body 7 except the first end 71 of the pulling body 7, the middle part of the index rope is wound on a fixed pulley arranged on the top of the derrick, and the other end of the index rope is connected with a safety belt worn on the derrick worker.
Under this condition, when using this to help and climb, when the derrick worker upwards scrambles on the derrick or from the derrick to the in-process on ground down, if the derrick takes place acutely to rock, then can drive on-vehicle guy rope and take place to rock, then can drive pull body 7 and take place to rock. When the pull body 7 shakes, the balance bar 8 and the balance rail 9 are driven to shake, the balance wheel 11 is located in a groove arranged on the second end 102 of the balance wheel support 10, a part between the first end 91 and the second end 92 of the balance rail 9 penetrates through a gap between the balance wheel 11 and the bottom of the groove, the first end 101 of the balance wheel support 10 is connected with the weighted roller 13, and a heavy object is contained in the weighted roller 13, so when the balance bar 8 and the balance rail 9 shake, the height of the first end 91 of the balance rail 9 is higher or lower than that of the second end 92 of the balance rail 9, at the moment, the balance wheel 11 slides along the balance rail 9 in the direction close to the part between the first end 91 and the second end 92 of the balance rail 9, namely the direction of the lowest part, under the gravity action of the weighted roller 13, the balance wheel 11 slides along the balance rail 9 in the direction opposite to the shaking direction of the balance rail 9 under the gravity action of the weighted roller 13 And (4) sliding. For example, the first end 91 of the balance rail 9 is on the left of the balance rail 9, the second end 92 of the balance rail 9 is on the right of the balance rail 9, when the balance rail 9 rocks to the left, the first end 91 of the balance rail 9 is at a higher height than the second end 92 of the balance rail 9, the lowest height of the portion between the first end 91 and the second end 92 of the balance rail 9 is close to the second end 92 of the balance rail 9, and the balance wheel 11 slides along the balance rail 9 in a direction close to the lowest height of the portion between the first end 91 and the second end 92 of the balance rail 9, that is, slides to the right along the balance rail 9 under the gravity of the weighted weight cylinder 13. In this way, the wobbling of the balance rail 9 and the balance bar 8, and thus the wobbling of the pulling body 7, can be reduced. When the pulling body 7 shakes slightly or does not shake, the climbing assistor can not rotate around the vehicle-mounted guy rope when moving along the vehicle-mounted guy rope, and then the index rope connected with the climbing assistor can not be wound together with the vehicle-mounted guy rope, so that a derrick can be conveniently climbed by a derrick worker.
It is worth noting that when the vehicle-mounted guy rope is used, the vehicle-mounted guy rope is inclined relative to the vertical line, and in order to facilitate the movement of the vehicle-mounted guy rope, the vehicle-mounted guy rope vertically passes through a space between the first bearing plate 1 and the second bearing plate 2, namely, the first bearing plate 1 and the second bearing plate 2 are both perpendicular to the vehicle-mounted guy rope, and at the moment, the first bearing plate 1 and the second bearing plate 2 are also inclined relative to the vertical line.
