Further, driver train comprises motor and speed reducer, and the output shaft of motor is connected with the input shaft of reductor, and described is coaxially arranged on reductor so that reductor drives coaxial rotating.
Further clean the Trolley positioning accurate accuracy in when walking in order to improve, the draw gear of this power plant indirect air cooling tower heat radiator fin cleaning machine also comprises traction stop control system, multiple stop optical isolation boards that control system comprises the driving control desk of photoelectric sensor switch, the work of driving driver train and is arranged in relevant washing station are stopped in this traction, photoelectric sensor switch is arranged on and cleans on Trolley, stop optical isolation board and respond to and coordinate mutually with photoelectric sensor switch, the signal output part of photoelectric sensor switch is connected with driving control desk.
Further, in order to ensure to clean the stroke safety of Trolley, avoid its overshoot phenomenon, described traction is stopped control system and is also comprised upper limit position switch and lower position switch, and the signal output part of upper limit position switch and lower position switch is all connected with driving control desk.
Further, single fold line grooves winding reel is provided with two.
Adopt after technique scheme, driver train makes coaxial rotating, two or more single fold line grooves winding reel is realized synchronous rotary, thereby two or cleaning Trolley of many steel wire hangs are realized, ensure that the lifting of cleaning Trolley is subject to equilibrium of forces, has improved stressed safety factor, steel rope stackable after-combustion on single fold line grooves winding reel, save the length of single fold line grooves winding reel, thereby greatly dwindled the overall dimensions of draw gear.
Brief description of the drawings
Fig. 1 is the structural representation of the draw gear of power plant indirect air cooling tower heat radiator fin cleaning machine of the present invention.
Detailed description of the invention
For content of the present invention is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation below.
As shown in Figure 1, a kind of draw gear of power plant indirect air cooling tower heat radiator fin cleaning machine, it comprises frame 1, coaxial 2, supporting seat 3, hoisting mechanism and driver train, hoisting mechanism has the single fold line grooves winding reel 4 of many groups and corresponding steel rope, the truss upper end of cleaning machine is fixed with reverse wheel, one end of every steel rope is connected to and cleans on Trolley through reverse wheel, the other end is wrapped on corresponding single fold line grooves winding reel 4, supporting seat 3 is arranged in frame 1, coaxial 2 can be rotated to support on supporting seat 3, driver train is flexibly connected with coaxial 2 to drive its rotation, single fold line grooves winding reel 4 is all sleeved on coaxial 2.Whole draw gear is fixed on the bottom of cleaning machine, maintains easily maintenance and maintenance.
As shown in Figure 1, driver train comprises motor 5 and reductor 6, and the output shaft of motor 5 is connected with the input shaft of reductor 6, and coaxial 2 are arranged on reductor 6 so that reductor 6 drives coaxial 2 rotations.
