Description

Technical Field

[0001] The utility model relates to the field of tower cranes, in particular to a horizontal 360-degree spraying device which can be lifted and lowered for a construction tower crane. Background Art

[0002] Tower crane, also known as tower crane, is the most commonly used lifting equipment on construction sites and is also an indispensable lifting equipment on construction sites. During the construction process, there is often a lot of dust on the construction site, and it is necessary to spray water regularly to remove dust. In addition, water is also needed to be sprayed on the surface of the building roughcast to properly prevent dryness. Today's buildings are generally very high, and the height of spraying water is difficult to reach. In addition, the construction ground is not flat. When removing dust, the efficiency of workers spraying water through a nozzle is very low and the operation is not safe.

[0003] To solve the above problems, the utility model patent named: A horizontal 360-degree spray device for construction tower crane (publication number: CN208771081U) discloses a horizontal 360-degree spray device that can be raised and lowered, which can achieve the effect of high-altitude spraying and effectively prevent dust from flying on the ground. However, the lifting and lowering of the device is relatively complicated, and it is not convenient to add water to the liquid storage tank. At the same time, the tower crane will lift the object and rotate it during operation, which may easily cause the liquid supply pipe to be entangled. Utility Model Content

[0021] Example: As attached Figure 1-5 As shown, the utility model is a horizontal 360° spray device for a construction tower crane that can be raised and lowered, including a rotating mechanism 2 installed in a longitudinal support column 1 of the tower crane, a telescopic mechanism 4 arranged at the bottom of a transverse support column 3 of the tower crane, and a base block is fixedly installed at the bottom of the longitudinal support column 1.

[0022] The rotating mechanism 2 includes a mounting frame 21 fixed in the longitudinal support column 1. The mounting frame 21 can be made of two support plates fixed in the longitudinal support column 1. A water pump 22 is arranged on the mounting frame 21. The water inlet of the water pump 22 is provided with a water pumping pipe 23 extending downward. The water outlet of the water pump 22 is connected to the water outlet pipe 24 through a rotating joint. The rotating joint can adopt an existing structure. Preferably, the rotating joint includes a water outlet head 25 fixed at the water outlet of the water pump 22. The water outlet pipe 24 is connected to the water outlet of the water pump 22. 4 is inserted into the water outlet head 25, and a sealing ring 26 is provided between the water outlet head 25 and the water outlet pipe 24. Two fixing rings 27 are fixedly installed at the bottom of the water outlet pipe 24. A sealing ring 28 is movably connected between the two fixing rings 27. The water outlet pipe 24 can rotate inside the water outlet head 25. The sealing ring 26 is used to seal the water outlet head 25 and the water outlet pipe 24 to prevent water from flowing out of the gap between the water outlet head 25 and the water outlet pipe 24 during the rotation process, thereby improving the practicality of the utility model.

[0023] The telescopic mechanism 4 includes a water pipe retractor 41 fixed on the transverse support column 3, a water supply hose 42 wound on the reel of the water pipe retractor 41, a motor for driving the reel to rotate is provided on the water pipe retractor 41, a connecting pipe 43 connected to the water outlet pipe 24 is provided at one end of the water supply hose 42, and a water feeder 5 is provided at the other end, and a water pump for connecting to the water outlet pipe 24 is provided on the connecting pipe 43. The reel of the water pipe retractor 41 rotates to wind the water supply hose 42 on the reel or to lower it from the reel, thereby controlling the height of the water feeder 5.

[0024] A sprayer 51 is provided at the bottom of the water feeder 5. The sprayer 51 is rotatably connected to the water feeder 5 via a hollow shaft. A driving device for driving the sprayer 51 to rotate is provided on the water feeder 5. The hollow shaft connects the sprayer 51 and the water feeder 5. The driving device is a motor fixed on the water feeder 5. Gear transmission is adopted between the motor and the hollow shaft. When the motor is started, the sprayer 51 can be driven to rotate.

[0025] Preferably, a plurality of water outlets 52 are provided on the outer peripheral wall of the sprayer 51, and the sprayer 51 can be driven by starting the motor, thereby increasing the water coverage area through centrifugal force and improving practicality.

[0026] Preferably, in order to ensure the stability of the pipeline connection, a rotator 11 is provided on the top of the longitudinal support column 1, and a support seat 31 is provided on the top of the rotator 11. The transverse support column 3 is fixed on the support seat 31. A hook is fixedly installed on the edge of one side of the bottom of the transverse support column 14. The end of the water outlet pipe 24 away from the rotary joint and the end of the connecting pipe 43 away from the water supply hose 42 are both fixed on the support seat 31, and the connection between the water outlet pipe 24 and the connecting pipe 43 is located inside the support seat 31.

[0027] When the utility model is in use, first, the water to be sprayed is pumped into the inside of the water outlet head 25 at the top through the water pump 22 through the water pump pipe 23, and the water is sent into the inside of the water outlet pipe 24 through the water outlet head 25. The water outlet head 25 can cross the middle of the rotator 11 and connect with the support seat 31. When the transverse support column 3 rotates through the rotator 11 at the top of the longitudinal support column 1, the water outlet pipe 24 is driven to rotate around the axis of the water outlet head 25. The sealing ring 28 fixed between the two fixing rings 27 at the bottom of the outer side of the water outlet pipe 24 is a structure for sealing the gap between the water outlet pipe 24 and the water outlet head 25. The sealing ring 28 is a movable connection structure. When the water outlet pipe 24 rotates in the water outlet head 25, the function of the sealing ring 28 is to prevent water from flowing out of the gap between the water outlet pipe 24 and the water outlet head 25. The sealing ring 26 plays a secondary sealing role to prevent water from flowing out; water is sent out from the water outlet pipe 24 and passes through the support seat 3 1 enters the interior of the water pump, and through the operation of the water pump, water is pumped into the connecting pipe 43, and water is sent into the interior of the water pipe retractor 41 from one side through the connecting pipe 43, and then the water enters the water supply hose 42 through the interior of the water pipe retractor 41. The rotation of the water pipe retractor 41 drives the water supply hose 42 to rotate, so as to achieve the purpose of adjusting the height of the water supply hose 42, and adjust the water supply hose 42 to a suitable height. The water flows from the water supply hose 42 through the water feeder 5 and enters the interior of the sprinkler 51. The water is pressurized and sprayed out from several water outlets 52 around it through the sprinkler 51, so as to form a water barrier to prevent dust from flying around and causing environmental pollution. When a large area is required to be covered, the sprinkler 51 is driven to rotate by the driving device, so that the sprayed water has centrifugal force, so that the water is sprayed over a larger area, achieving the effect of large-area coverage.
