Embodiment Construction

[0005] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Orderly operations are performed as shown in the description of the drawings. After the iron sealing of the lifting part of the pole holding pole is completed, first loosen 10 correspondingly, so that the pole holding pole is slightly biased to be stressed, so as to respectively move the two poles 7 in the corresponding direction to pin them at a high place. After the four 7 pins are fixed, the four 10s are adjusted to make the four 8s and 9s give the same speed, and then the winch mill can be started to lift the holding rod and move the four support ropes 11 pins, then loosen the winch mill and remove 5, and then go round and begin again for operation Until the iron tower is finally completed. The above scheme is adopted to achieve the purpose of safe, balanced lifting and high-efficiency construction of the poles in the present invention.

Abstract

The invention discloses a complete set technology of a telescopic series derrick balance lifting system. The technology comprises that four brake handles (10) and four synchronous separation and reunion right-angle tooth-connected rotating wheels (8) and (9) are designed. The complete set technology further comprises an advanced method for using and operating (8), (9) and (10). The telescopic series derrick balance lifting system is characterized in that diagonal traction of a long and heavy steel wire rope which is originally used for lifting a derrick is eliminated; four short, light and flexible four-corner tractors (3) are rotationally converged on (5) through four (4); the (5) is used for transmitting power on (6) to keep the lower end of the derrick in the center of an iron tower in the lifting process. Four rotating wheels (8) and (9) are separated and combined in a combined manner, and four (7) can be moved correspondingly and respectively to make preparation for lifting of the derrick. The derrick is adjusted through the (10) during lifting, and the (8) and the (9) are adjusted to be synchronous and at the same speed in the lifting process by the derrick through the (10). By adopting the complete set technology and the advanced method thereof, the potential safety hazard that the derrick is deviated from the gravity due to the fact that the original conservative operation is eliminated, the human fatigue can be relieved, the operation time is shortened, and the construction benefit is increased. The telescopic series derrick balance lifting system is worthy of large-scale popularization.

Description

Technical field: [0001] The invention is applied to the construction of erecting iron towers for power transmission lines. Especially for the construction of ultra-high and heavy iron towers. Background technique: [0002] Diagonal traction is generally used for erecting towers on power transmission lines. The traction rope is long and heavy, and it is very laborious for high-altitude personnel to operate. Whether it is internal waves or external waves to control the poles, the directions of the four corners are all manually operated. , There is always an inevitable difference in the tightening speed mastered by it, so it is difficult to maintain the vertical rise of the pole during the lifting process and deviate arbitrarily, which not only consumes a lot of labor and time, but also is prone to safety accidents. For this reason, the telescopic series pole-holding balance lifting system is studied to solve this construction problem and improve safety benefits. Invention c...
