Description
Technical field
The present invention relates to the traction apparatus of a kind of power plant indirect air cooling tower heat radiator fin cleaning machine.
Background technology
At present, the scarcity day by day of water resource, promote air cooling technique fast-developing in power industry.In China's " rich coal hydropenia " area, the Major Cooling Methods of thermal power plant has Direct Air-Cooled and indirect air cooling.Wherein, indirect air cooling is mainly made up of condenser, air cooler and radiator, and radiator is divided into steel or aluminum.The operation principle of indirect air cooling system: recirculated cooling water enters the water side of surface condenser, by metal surface heat exchange, the turbine discharge of cooling condenser side, cooling water after being heated is pumped to indirect air cooling head tower by recirculated cooling water, carrying out heat exchange by aluminum air cooling heat radiator and air, cooling water returns again to surface condenser cooling turbine discharge after being cooled down by air.
The cooling system of this employing hybrid indirect air convection current refrigerating mode, Shi Quan factory water consumption can reduce more than 60%.Its shortcoming is: the radiating fin of cooling tower is all exposed to the external world, provides implantation for each pollutant in air, and these attachment moment affect the effect of cold and hot exchange.Accumulate increasingly severe attachment, the operating of steam turbine can be made to occur abnormal, reduce the delivery efficiency of steam turbine, cause increasing of generating power consumption, thus add production cost.Unit operation is it was verified that when convection current reduces by 20%, the rear pressure of turbine increases by 33%, thus has influence on safe operation and the generating efficiency of equipment.
Lifting at cleaning machine is drawn in design, one is to use the most complete uniform nozzle pattern, this design has avoided trailer system link, but the mode of uniform nozzle is in the range of the elevation of 30 meters, have that upper and lower nozzle water yield difference is excessive, poor excessive a, defect that cleaning performance is poor of two-way pressure；Two is to use polyurethane coaxial synchronous band tractive manner, there is the walking problem that positioning accurate accuracy is poor, Timing Belt is the most aging, the length of service is low.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, the traction apparatus of a kind of power plant indirect air cooling tower heat radiator fin cleaning machine is provided, it can reduce the overall dimensions of traction apparatus, ensure to promote the uniform force of object, it is thus possible to improve its service life, increase and use safety coefficient.
In order to solve above-mentioned technical problem, the technical scheme is that the traction apparatus of a kind of power plant indirect air cooling tower heat radiator fin cleaning machine, it includes frame, coaxially, support seat, hoisting mechanism and drive mechanism, hoisting mechanism has many single fold line grooves winding reels of group and corresponding steel wire rope, one end of every steel wire rope is connected to clean on locomotive, the other end is connected on corresponding single fold line grooves winding reel, support seat to be arranged in frame, coaxially can be rotated to support on support seat, drive mechanism is flexibly connected to drive it to rotate with coaxial, described single fold line grooves winding reel is all sleeved on coaxial.
Further, drive mechanism includes motor and speed reducer, and the output shaft of motor is connected with the power shaft of reductor, and described is coaxially mounted on reductor so that reductor drives coaxial rotating.
Further for the positioning accurate accuracy improved when cleaning locomotive walking, the traction apparatus of this power plant indirect air cooling tower heat radiator fin cleaning machine also includes that control system is stopped in traction, this traction is stopped control system and is included photoelectric sensor switch, drives driving panel and being arranged in multiple stop optical isolation boards of relevant washing station of drive mechanism work, photoelectric sensor switch is arranged on cleaning locomotive, stopping optical isolation board to sense mutually with photoelectric sensor switch and coordinate, the signal output part of photoelectric sensor switch is connected with driving panel.
Further for ensureing to clean the safety travel of locomotive, it is to avoid its overshoot phenomenon, described traction is stopped control system and is also included that the signal output part of upper limit position switch and lower position switch, upper limit position switch and lower position switch is all connected with driving panel.
Further, single fold line grooves winding reel is provided with two.
After have employed technique scheme, drive mechanism makes coaxial rotating, two or more single fold line grooves winding reel realizes synchronous rotary, it is achieved thereby that two or one cleaning locomotive of many steel wire hangs, ensure that cleaning locomotive promotes the balance of stress, improves the safety coefficient of stress, steel wire rope stackable after-combustion on single fold line grooves winding reel, save the length of single fold line grooves winding reel, thus be greatly reduced the overall dimensions of traction apparatus.
Accompanying drawing explanation
Fig. 1 is the structural representation of the traction apparatus of the power plant indirect air cooling tower heat radiator fin cleaning machine of the present invention.
Detailed description of the invention
Being clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, a kind of traction apparatus of power plant indirect air cooling tower heat radiator fin cleaning machine, it includes frame 1, coaxial 2, support seat 3, hoisting mechanism and drive mechanism, hoisting mechanism has many single fold line grooves winding reels 4 of group and corresponding steel wire rope, the truss upper end of cleaning machine is fixed with reverse wheel, one end of every steel wire rope is connected to clean on locomotive through reverse wheel, the other end is wrapped on corresponding single fold line grooves winding reel 4, support seat 3 to be arranged in frame 1, coaxial 2 can be rotated to support on support seat 3, drive mechanism is flexibly connected to drive it to rotate with coaxial 2, single fold line grooves winding reel 4 is all sleeved on coaxial 2.Whole traction apparatus is fixed on the bottom of cleaning machine, maintains easily maintenance and maintenance.
As it is shown in figure 1, drive mechanism includes motor 5 and reductor 6, the output shaft of motor 5 is connected with the power shaft of reductor 6, and coaxial 2 are arranged on reductor 6 so that reductor 6 drives coaxial 2 to rotate.
