Description

Technical Field

[0001] The utility model relates to the technical field of paint spraying equipment, in particular to an adjustable remote paint spraying device for a standard section of a tower crane. Background Art

[0002] Tower crane is a revolving crane with its boom mounted on the top of a tall tower. It has a large working space and is mainly used for vertical and horizontal transportation of materials and installation of building components in housing construction. It consists of three parts: metal structure, working mechanism and electrical system.

[0003] The standard section of a tower crane is composed of a main chord, a web and a connecting sleeve. It needs to be flipped over many times on the operating platform during painting. The commonly used operating platform support positions will leave support points on the surface of the standard section, resulting in incomplete paint coverage. At the same time, due to the heavy weight and high height of the standard section, a lifting mechanism must be used to lift it again and then place the operating platform after flipping each time, which is troublesome to operate. In addition, there are many models and sizes of standard sections of tower cranes on the market. Each time painting is performed, the position of the operating platform must be adjusted according to the corresponding size, which restricts production efficiency. The traditional painting method is to manually spray paint on the standard section with a handheld spray gun, which cannot effectively reduce the damage of paint to operators during the painting process. Therefore, an adjustable remote painting device for the standard section of a tower crane is proposed to address the above problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0005] The invention discloses an adjustable remote painting device for standard sections of a tower crane, comprising a motor, a base, a turntable, a paint supply mechanism, a slide and a base frame.

The rotating shaft in the middle of an inner side of the base frame is meshed and connected with transmission teeth at the bottom of the slide. The top of the slide is connected to the bottom of the turntable. A plurality of connecting rods are fixed to one side of the turntable. The connecting rods match connecting sleeves at the ends of the standard sections of a tower body of the tower crane and are provided with anti-slip nuts. A limiting rod connected to the base is provided on the other side. One end of the limiting rod is connected to a circular positioning hole in the middle of the base and is provided with an adjustable locking nut. A spray head is provided above the turntable and is conductively connected to the paint supply mechanism through a paint supply pipe.

[0007] Preferably, the number of the connecting sleeves is plural, and the number of the connecting sleeves corresponds to the number of the connecting rods.

[0008] Preferably, one end of the turntable limiting rod is connected to the circular positioning hole in the middle of the base, and the gap between the circular positioning hole and the limiting rod is filled with a lubricating substance.

[0009] Preferably, the nozzle is mounted on a cross bar of the fixing frame, the cross bar is slidably connected to the inside of the fixing frame, a visualization mechanism is provided below the protruding rods at both ends of the nozzle, and the nozzle is conductively connected to the paint supply mechanism through a paint supply pipe.
