Technical Field

The invention relates to a tower crane, in particular to a tower crane spraying system.

Background

At present, can produce the dust of different degree in the building work process, bring very big influence for city life, also have the mode that adopts spray water smoke among the actual operation process and prevent dust, but this kind of mode coverage is little, and dustproof effect is not good. At present, a lot of construction sites adopt the tower crane to spray water mist to prevent dust, so that the operation range is expanded to a certain extent, but one set of spraying system needs to be installed on the tower crane, the structure is complex, the installation is inconvenient, and the cost is high. Because the tower crane is arranged higher, the hoisting and falling positions of the object are far lower than the height of the tower crane, the spraying effect of the spray head on the hoisted object is poor, and dust is easily generated in the hoisting and falling processes of the object, so that the dustproof effect in the hoisting process of the object is poor.

Disclosure of Invention

The invention overcomes the defects of complex structure, inconvenient installation, high cost and poor spraying effect on a lifted object of a tower crane spraying system, and provides the tower crane spraying system which has the advantages of simple structure, convenient installation, low cost, good spraying effect on the lifted object, good dust prevention effect due to the fact that the object is sprayed in the lifting and putting down processes.

In order to solve the technical problems, the invention adopts the following technical scheme: a tower crane spraying system comprises a water storage tank arranged on the upper part of a tower body, a spraying mechanism arranged on a tower crane boom, and a hanger which can be transversely movably arranged on the boom, wherein a transmission mechanism used for driving the hanger to translate is arranged on the boom, the transmission mechanism comprises a driving wheel, a driven wheel and a guy rope in transmission connection between the driving wheel and the driven wheel, the hanger is connected with the guy rope, a liftable sling is arranged on the hanger, the lower end of the sling is connected with a closed spraying cylinder, a piston is arranged in the spraying cylinder in a matching way, a suspender is connected on the piston, the suspender extends out of the lower end of the spraying cylinder, the lower end of the suspender is connected with a lifting hook, a return spring is arranged between the piston in the spraying cylinder and the bottom surface of the spraying cylinder, the piston is abutted against the upper end of the spraying cylinder, the upper end and the lower end of the, a plurality of upper spraying holes are formed in the side wall of the upper part of the spraying cylinder, and water outlet one-way valves are arranged in the upper spraying holes and the lower spraying holes; the spraying mechanism comprises a spraying pipe, a piston cylinder and a rotary disc, the rotary disc is fixedly connected with a driving wheel, a plurality of spraying heads arranged at intervals are arranged on the spraying pipe, a driving plug is arranged in the piston cylinder in a matched mode, a push-pull rod is hinged between the driving plug and the edge of the rotary disc, the end, far away from the push-pull rod, of the piston cylinder is communicated with a water pumping pipe and a water drainage pipe, the water pumping pipe is communicated with a water storage tank, the water drainage pipe is communicated with the spraying pipe, and a water pumping.

Before the tower crane lifts the object, the spray cylinder is filled with water. When the object is lifted, the lifting hook is hung on the object, then the object is lifted upwards, under the action of gravity, the piston is pulled by the lifting rod to move downwards together, water below the piston in the spray cylinder is sprayed downwards from the lower spray hole, the object and the periphery of the object are sprayed, and dust is prevented from being generated when the object is just lifted off the ground. The article can produce certain shake at the in-process that rises, and the piston constantly reciprocates under return spring's effect this moment to make rivers constantly spray the outside blowout in hole and the last spraying hole from spraying down, spray the article, prevent that the article from shaking and producing the dust. After the article arrived the assigned position and transferred ground, under the return spring effect, piston rebound, the water of piston top outwards spout through last spraying hole in the spray cylinder, sprays the article, prevents that the article from transferring the process and producing the dust. The piston moves upwards, and water in the water storage tank is pumped into the cavity below the piston in the spraying cylinder through the water inlet pipe at the lower end of the spraying cylinder. The piston moves downwards, and water in the water storage tank is pumped into the cavity above the piston in the spraying cylinder through the water inlet pipe at the upper end of the spraying cylinder. When the object is lifted and translated, the hanger is translated under the driving of the transmission mechanism, at the moment, the driving wheel rotates to drive the turntable to rotate together, so that the push-pull movement of the push-pull rod is realized, the driving plug reciprocates in the piston cylinder, water in the water storage tank is extracted in the process that the driving plug moves outwards, and the water in the piston cylinder is sprayed outwards through the spray header on the spray pipe in the process that the driving plug moves inwards to prevent dust. The tower crane spraying system is simple in structure, convenient to install, low in cost, good in spraying effect on a lifted object, good in dustproof effect due to the fact that the object is sprayed in the lifting and putting-down processes.
