Detailed Implementation

[0023] To make the objectives, methods, and advantages of the embodiments of the present invention clearer, the method solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Example 1:

[0025] like Figure 1-5 As shown, a steel section drying device includes: a placement platform 1 with an inclined surface, a fan 2, an air outlet duct 3, and a limiting rolling assembly 4; one end of the placement platform 1 is connected to a support column a5; the other end of the placement platform 1 is connected to a support column b6; the bottom wall 31 of the fan 2 is connected to the top wall of the support column a5; the fan 2 is connected to the air outlet duct 3; the end of the air outlet duct 3 is connected to the support column b6; both the support column a5 and the support column b6 are provided with cavities; the limiting rolling assembly 4 is provided inside the cavity; the limiting rolling assembly 4 includes a sleeve 4. 1. An electric telescopic rod 42, a limiting block 43, and a first telescopic cylinder 44; the sleeve 41 is detachably connected to the electric telescopic rod 42; the first telescopic cylinder 44 is connected to the side wall of the cavity; the first telescopic cylinder 44 is connected to the limiting block 43; the limiting block 43 abuts against the side wall of the electric telescopic rod 42; the telescopic direction of the electric telescopic rod 42 is perpendicular to the telescopic direction of the first telescopic cylinder 44; a rolling opening 51 is provided on the side of the cavity near the support platform; the sleeve 41 can extend out from the rolling opening 51.

[0026] In the specific implementation process, after the clamping components in the empty vehicle transportation system clamp the steel section above the placement platform 1... Figure 3 The electric telescopic rod 42 extends, causing the sleeve 41 to fit over both ends of the steel profile. The clamps loosen, and the steel profile is now parallel to the inclined surface of the placement platform 1, with the limiting block 43 abutting against the electric telescopic rod 42. Then, the fan 2 is started to air-dry the front and sides of the steel profile. Next, the first telescopic cylinder 44 shortens. During the smooth shortening process of the first telescopic cylinder 44, the steel profile, under its own weight, moves along... Figure 2 The inclined surface of the placement platform 1 shown rolls slowly downwards. Assuming the steel profile is square steel, the extension and retraction stroke of the first telescopic cylinder 44 can be controlled using existing control technology. The shortening process is repeated three times, with the blower 2 blowing on a different surface of the steel profile each time, achieving uniform drying of all surfaces. The drying time for each surface can also be controlled using existing technology. The sleeve 41 and the electric telescopic rod 42 can be connected by threads to allow for replacement of the sleeve 41 to accommodate steel profiles of different shapes. After drying is complete and the steel profile is transferred, the first telescopic cylinder 44 resets.

[0027] In this embodiment, the abutting wall of the abutting block is an arc surface that matches the side wall of the electric telescopic rod 42.

[0028] During the actual implementation, the abutment block and the electric telescopic rod 42 are in full contact to disperse stress.

[0029] In this embodiment, the hollow section of the sleeve 41 has a rectangular cross-section.

[0030] In practice, common steel profiles include square steel, hexagonal steel, I-beams and channel steel. If the hollow section is circular, the steel profile can rotate in the hollow section, but it cannot be flipped. Therefore, it is set to a rectangle that is applicable to most common steel profile shapes.

[0031] In this embodiment, the air outlet of the fan 2 is provided with a flow control component 21; the flow control component 21 includes a concave plate 211, a wing plate 212, and a second telescopic cylinder 213; the bottom plate 2111 of the concave plate 211 abuts against the air outlet; the two side plates 2112 of the concave plate 211 divide the internal space of the air outlet pipe 3 into three parts along the width direction of the air outlet pipe 3; the bottom wall 31 of the air outlet pipe 3 and the bottom plate 2111 of the concave plate 211 are both provided with a plurality of air holes; each end of the bottom plate 2111 of the concave plate 211 is connected to a wing plate 212; the side wall of the air outlet pipe 3 is provided with an opening for the wing plate 212 to pass through; the protruding end of one of the wing plates 212 is connected to the second telescopic cylinder 213; the second telescopic cylinder 213 is provided on the support column a5.

[0032] In the specific implementation process, the air outlet duct 3 needs to air dry the steel profile during its rolling process. Therefore, the air outlet duct 3 has a large coverage area. If all the air outlets were to discharge air during the rolling process, it would result in a significant waste of air energy. Therefore, a system with appropriate ventilation is installed. Figure 4 The flow control component 21 shown uses existing control technology to control the extension and retraction of the second telescopic cylinder 213 according to the four drying positions of the steel profile, so as to adjust the position of the concave plate 211. Air passes through the gap of the concave plate 211, which is directly opposite the steel profile to be dried.

[0033] In this embodiment, the bottom wall 31 of the air outlet duct 3 is provided with a guide groove 311; the bottom end of the wing plate 212 is placed inside the guide groove 311.

[0034] In the specific implementation process, such as Figure 5 As shown, the guide groove 311 serves a guiding function and can also disperse the resistance encountered by the second telescopic cylinder 213 during extension and retraction, thereby increasing the lifespan of the second telescopic cylinder 213.

[0035] In this embodiment, the side wall of the placement platform 1 is provided with a transfer platform 11; the orthographic projection of the air outlet duct 3 is outside the transfer platform 11.

[0036] In the specific implementation process, such as Figure 2 As shown, after air drying, the electric telescopic rod 42 retracts, and the steel profile slides along the inclined surface of the placement platform 1 to the transfer platform 11. At this time, the top of the steel profile will not be blocked by the air outlet pipe 3, which facilitates the transfer of the empty vehicle transport system. If there is no transfer platform 11, the limiting rolling assembly 4 needs to move the air-dried steel profile to ensure that the air outlet pipe 3 does not block the steel profile before the steel profile is transferred, which would affect the air drying efficiency of the device.

[0037] In this embodiment, both the top of the support column a5 and the support column b6 are provided with sliding rails; the sliding rails are connected to the moving plate 61; the moving plate 61 on the support column a5 is connected to the fan 2; the moving plate 61 on the support column b6 is connected to the moving block 62; the moving block 62 is connected to the end of the air outlet pipe 3.

[0038] In the specific implementation process, such as Figure 1 As shown, initially, the fan 2 and the air outlet pipe 3 are moved as a whole by the moving plate 61. Then, the steel profile to be dried is placed on the placement platform 1, the moving plate 61 is reset, and the fan 2 is turned on. The sliding connection achieved by the track is existing technology and will not be described in detail.

[0039] In this embodiment, the sleeve 41 is provided with ventilation holes.

[0040] In the actual implementation process, the sleeve 41 will cover both ends of the steel section, so ventilation holes are provided to facilitate the full drying of the steel section.

[0041] In this embodiment, the fan 2 outputs ambient temperature air.

[0042] In practice, the steel profiles are often exposed to the environment. When the ambient temperature is low, if the fan 2 blows hot air, the warm steel profiles after drying will be exposed to cold air, and water vapor will condense on the surface.

[0043] The above are merely preferred embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
