Working method of tower crane spraying device for construction site capable of improving dust removal effect
Technical Field
The invention relates to the technical field of building equipment, in particular to a working method of a tower crane spraying device for a building site, which can improve the dust removal effect.
Background
In daily life and production, various air pollutants discharged to the nature in cities every day bring harm to the human body, production and life. The construction site is a serious disaster area of urban air pollution, and becomes one of main pollution sources influencing urban air quality. Meanwhile, the temperature on the construction site is close to 50 ℃ in summer, the construction operation cannot be carried out at all in the time period, particularly in the time period from 12 o 'clock to 4 o' clock in the afternoon, the existing equipment is a fog gun machine, fence spraying equipment and the like, but the range of temperature reduction and dust removal is small, and the effect is poor.
In order to solve the problems, the tower crane spraying device with the patent number of CN201410439656.3 is disclosed, which comprises a base, a tower hanger, a balance arm and a lifting arm, wherein the balance arm and the lifting arm are horizontally connected to the tower hanger; the horizontal water supply pipe is connected with the vertical pipeline through a rotary joint.
The scheme effectively adsorbs dust particles and impurities in the air, plays a role in dust fall, and simultaneously sprays a period of time at high altitude, the ground forms a wet state, and dust can be effectively pressed and lifted again. The probability of high-temperature heatstroke of workers is reduced, and the personal safety of the workers is guaranteed.
This solution has several disadvantages:
1. the spraying direction of the spraying head cannot rotate, so that the spraying range in a single time interval is limited, the water supply pipe is fixed on the tower crane and cannot be wound, and the service life of the water supply pipe is greatly shortened under long-time insolation;
2. because the tower crane is higher, air flows in the air, so that water mist floats away, and the dust cannot be quickly removed from an area with much dust in time, so that the dust removal effect is poor;
3. water mist is sprayed out of the tower crane for a long time, so that the tower crane truss is corroded, the service life of the tower crane is also damaged, and the safety of workers is reduced;
4. the tower crane needs to be cleaned and maintained for a long time, and the scheme cannot spray water to the whole truss.
