Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coatings, in particular to a spraying device for fire retardant coatings with adjustable height. Background Art

[0002] Fire retardant coatings are divided into two categories: intumescent and non-intumescent. They are mainly used in China's building structures to improve the fire resistance of building structures. The fire retardant coating's fire retardant principle is mainly due to the special properties of the fire retardant coating, which can delay the flame temperature from being transmitted to the protected substrate. In addition, the fire retardant coating will decompose some inert gases when heated, thereby delaying the flame burning speed.

[0003] The existing spraying of protective coatings is usually done manually with a handheld nozzle. When encountering a high wall, a ladder is needed to spray the upper part, which is inefficient and dangerous. In addition, the existing coating devices directly fix the nozzle on a fixed frame and cannot adjust the angle of the nozzle, so that the device can only spray vertically or horizontally distributed walls, which is relatively limited in use. Therefore, we propose a height-adjustable fire retardant coating spraying device to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a fire retardant coating spraying device with adjustable height to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, limiting grooves are provided on both sides of the lower part of the third fixed block, bolts are slidably clamped inside the two limiting grooves, nuts are threadedly installed on the lower parts of the two bolts, sliding grooves are provided on both sides of the second fixed block, the lower parts of the two bolts are slidably clamped inside the sliding grooves, and the two nuts are in contact with the bottom ends of the sliding grooves, the top end of the limiting rod is fixedly installed with the first fixed block, the top end of the reciprocating screw rod is rotatably installed on the bottom end of one side of the first fixed block, a handle is fixedly installed on the top end of one side of the bottom plate close to the paint box, and brake wheels are fixedly installed at the four corners of the top end of the bottom plate.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] 1. By setting a reciprocating screw, the first bevel gear and the second bevel gear are rotated under the drive of the motor, that is, the reciprocating screw is driven to rotate, and the sliding block can move up and down under the limit of the limit rod, so that the height of the nozzle can be adjusted, and then it can replace manual holding of the nozzle to climb up to a high place for operation, which reduces the work intensity and improves the work efficiency;

[0011] 2. By setting a worm wheel and a worm, the second fixed block and the third fixed block are limited under the cooperation of the bolt and the nut. By rotating the worm and cooperating with the worm wheel, the third fixed block is driven to slide on the upper part of the second fixed block, and the angle of the nozzle is adjusted. This solves the problem that the existing paint equipment can only be used for spraying on vertical or horizontal walls, making it more widely used. BRIEF DESCRIPTION OF THE DRAWINGS
