Description

Technical Field

[0001] The utility model relates to a building construction tower crane. Background Art

[0002] A tower crane, also known as a tower crane or tower crane, originated in Western Europe. It is a rotating crane with a boom mounted on top of a tall tower. It has a large operating area and is primarily used for vertical and horizontal material transportation and the installation of building components in housing construction.

[0003] Construction sites usually generate a large amount of dust. To prevent the dust from spreading, some existing tower cranes are equipped with spray devices to spray and reduce the dust on the construction site. However, the spray devices on the tower cranes are mostly fixed, and it is inconvenient to adjust the spray range of the spray devices. Therefore, the dust can only be processed within a specific range, which makes it difficult to improve its flexibility and has certain limitations.

[0004] Therefore, it is necessary to provide a construction tower crane to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a building construction tower crane to solve the problems raised in the above background technology.

[0006] In order to solve the above problems, the present invention adopts the following technical solutions:

[0007] A construction tower crane comprises a tower crane body, a cylinder is provided on the tower crane body, a suspension bracket is slidably provided at the bottom of one end of the tower crane body, the cylinder output shaft is connected to the suspension bracket, a mounting box is provided at the bottom of the suspension bracket, a rotating tube is rotatably installed in the mounting box through a bearing, a reduction motor is provided on one side of the mounting box, the reduction motor is transmission-connected to the rotating tube, a sprinkler head is connected to the bottom of the rotating tube, a water tank is provided on one side of the tower crane body, a water pump is provided on the top of the water tank, an input end of the water pump is connected to the water tank, an output end of the water pump is connected in sequence with a hose and a docking pipe, the docking pipe is fixedly penetrated through the suspension bracket and one end extends into the interior of the rotating tube.

[0008] Preferably, the output shaft of the reduction motor passes through the mounting box and is connected to a worm, and a worm wheel is fixedly sleeved on the outer wall of the rotating tube, and the worm wheel is meshedly connected to the worm.

[0009] Preferably, two fixed blocks are provided at the bottom of one side of the tower crane body, a cross bar is fixedly provided between the two fixed blocks, a sliding sleeve is provided at the top of the suspension frame, and the sliding sleeve is slidably connected to the cross bar.

[0010] Preferably, a rubber sealing ring is provided inside the rotating tube, and the inner surface of the rubber sealing ring contacts the outer surface of the butt-joint tube.

[0011] The beneficial effects of the present invention are as follows: water is added to the water tank and the water pump is started. The water in the water tank passes through the hose, the docking tube, and the rotating tube in sequence, and is finally sprayed downward from the sprinkler head, thereby reducing dust. The cylinder output shaft is extended and retracted to drive the suspension frame to move laterally, thereby driving the sprinkler head below it to move laterally to adjust the lateral position of the spray. The reduction motor is started to drive the rotating tube to rotate, thereby allowing the sprinkler head to be rotated and adjusted to reduce dust at different circumferential positions. Through the above arrangement, the range of the tower crane spray dust reduction can be expanded, thereby effectively reducing dust at different locations and improving its flexibility.
