Description

Technical Field

[0001] The utility model relates to the technical field of spraying equipment, and particularly relates to a simple column and beam spraying device. Background Art

[0002] Columns and beams refer to the pillars and crossbeams in a building structure. They jointly support the weight and structure of the building and are an essential part of the building. A column is a vertical structure in a building that mainly bears the pressure and weight from the upper structure. It is usually fixed to the foundation and supports beams and other horizontal structures. The shape and size of the column are determined according to the design and load-bearing requirements of the building to ensure the stability and safety of the structure. A beam is a horizontal structure that mainly bears lateral tensile and compressive forces and plays a role in transmitting gravity. It is supported on walls or columns and supports floor slabs and other floor structures, transferring the weight from one support point to another. The design and construction of the beam consider its span and load-bearing capacity to ensure effective dispersion and transmission of the weight. Columns and beams are basic elements in a building structure, and their design and construction are crucial for the stability and safety of the building. Most columns and beams used in building construction are square or circular as load-bearing structures, and the decoration and beautification of columns and beams also affect the coordination of the overall appearance of the building. Generally, columns and beams need to be carved and shaped, and then manually painted to beautify the appearance. However, columns and beams are relatively high, making manual painting difficult and inefficient. Content of the Utility Model

Detailed Embodiment

[0014] The present utility model will be further explained and illustrated below in conjunction with the drawings and specific embodiments.

[0015] Embodiment: As shown in the figure, a simple column-beam spraying device of the present utility model includes a support base 1, an adjusting rod 2 is connected to the support base 1, the top end of the adjusting rod 2 is rotatably connected to a clamping mechanism 3, the clamping mechanism 3 includes a housing 4, a spring 5, a straight rack 6, a gear 7, a clamping arm 8, a rotating shaft 9 and a traction rope 10. One end of the spring 5 is fixedly connected inside the housing 4, and the other end is fixedly connected to the straight rack 6. Two gears 7 are meshed on both sides of the straight rack 6. The gears 7 are rotatably connected to the end of the housing 4 away from the adjusting rod 2. A semi-circular clamping arm 8 is fixedly connected to the gear 7. The clamping arms 8 on the two gears 7 are symmetrically installed. A rotating shaft 9 fixed to the housing 4 is provided at the lower end of the straight rack 6. A traction rope 10 is wound around the rotating shaft 9. One end of the traction rope 10 passes through the housing 4, and the other end is fixed to the bottom surface of the straight rack 6. A hook head in limit connection with the housing 4 is also provided on the upper surface of the straight rack 6. A support mechanism 11 is vertically provided on the housing 4, and a spraying mechanism 12 is also provided on the clamping arm 8.

[0016] The support mechanism 11 includes fixing rings 13 symmetrically arranged up and down on the housing 4. A support column 14 is slidably connected inside the fixing ring 13. A roller 15 is fixedly connected to one end of the support column 14 close to the clamping arm 8, and the other end is an L-shaped bent part. A spring 5 is also connected between the bent part and the support column 14; the support column 14 is supported on the column-beam through the spring 5 to realize the auxiliary support for the clamping mechanism 3.

[0017] The spraying mechanism 12 includes an arc-shaped rack 16 slidably connected to the clamping arm 8. The length of the arc-shaped rack 16 is half of that of the clamping arm 8. Nozzles 17 are fixedly connected to both ends thereof. A spray pipe 18 is connected between the two nozzles 17. A motor 19 is fixedly connected to the outer side surface of the clamping arm 8. A gear 7 meshing with the arc-shaped rack 16 is installed on the motor 19. The spray pipe 18 is connected to an external material bucket, and the motor 19 is electrically connected to an external drive; during use, the paint is conveyed from the external material cylinder to the nozzles 17 through the spray pipe 18 and sprayed outwards. Since the clamping arm 8 is semi-circular and the length of the arc-shaped rack 16 is half of that of the clamping arm 8, the included angle between the nozzles 17 at both ends of the clamping arm 8 is ninety degrees. When the motor 19 drives the gear 7 to rotate, it will drive the arc-shaped rack 16 to move on the clamping arm 8. At this time, the nozzles 17 will rotate on the clamping arm 8 accordingly. The limit rotation angle is half of the length of the clamping arm 8, that is, forty-five degrees. When the four nozzles 17 on the two clamping arms 8 rotate, they will cover the entire outer surface of the column-beam without dead angle for 360 degrees. At the same time, since the support mechanism 11 is distributed up and down on the clamping mechanism 3, there is no blockage during spraying to achieve full spraying.

[0018] The adjusting rod 2 includes a first telescopic rod 20, a second telescopic rod 21 and a connecting bolt 22. The second telescopic rod 21 is sleeved inside the first telescopic rod 20. Through connection holes are provided on the outer walls of both of them, and the connecting bolt 22 is installed in the connection holes of both of them. Specifically, three connection holes are equidistantly provided on the first telescopic rod 20, and more than three connection holes are provided on the second telescopic rod 21, facilitating the alignment of the connection holes on the two telescopic rods when adjusting the height, facilitating the insertion of the connecting bolt 22, so as to control the height of the adjusting rod 2.

[0019] A disc seat 23 rotatably connected thereto is further provided at the top end of the second telescopic rod 21. The disc seat 23 can rotatably connect the second telescopic rod 21 with the clamping mechanism 3. After the clamping mechanism 3 is in place, the rotation direction of the second telescopic rod 21 can be adjusted through the disc seat 23. On the one hand, it is convenient for the installation and fixation of the connecting bolt 22, and on the other hand, the orientation of the support seat 1 can be controlled to improve the applicability.

[0020] The utility model supports the clamping mechanism in the air through the support seat and the adjusting rod, and then uses the support mechanism to assist in supporting the column beam to prevent the clamping mechanism from tipping over. The spraying mechanism located on the clamping arm can drive the spray head to spray the surface of the column beam under the control of an external drive, and at the same time, the spraying position can be rotated and adjusted to achieve dead-angle-free coverage, without the need for manual high-altitude operation and with a simple structure and convenient use.

[0021] The above is only used to illustrate the technical solution of the utility model and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the utility model shall be covered within the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
