Technical Field

[0001] The present invention belongs to the technical field of construction equipment, and particularly relates to a heating device for architectural coatings. Background Art

[0002] During the construction of bridges and other buildings, a layer of waterproof coating needs to be applied to the surface of the bridge. The waterproof coating needs to be heated or treated with ultraviolet light before the small molecules of the material can be polymerized into large molecules. Existing heating devices are large in size and not easy to move. Especially when treating coatings on bridge enclosures, it is very inconvenient. At the same time, the mechanism design of traditional heating devices is unreasonable, resulting in most of the energy being dissipated on the shell and not being effectively utilized. Summary of the Invention

[0003] The purpose of the present invention is to provide a heating device for architectural coatings that splits the ultraviolet irradiation part into three parts, unfolds the ultraviolet irradiation part during operation, and retracts it after the operation is completed, reducing the occupied space. The secondary ultraviolet irradiation part extracts external air through the Venturi tube effect to cool its interior, and reflects the ultraviolet rays above the ultraviolet lamp tube to below the ultraviolet lamp tube through a reflector, improving the energy utilization rate of the device.

[0004] Based on the above purpose, the present invention adopts the following technical solution: A heating device for architectural coatings, including a trailer and an ultraviolet module provided at its front end. A lifting module is provided at the left end of the trailer, and the lifting module is connected to the ultraviolet module through a mounting frame provided on its left side. The ultraviolet module includes a main ultraviolet irradiation part connected to the mounting frame, and also includes two secondary ultraviolet irradiation parts hinged to the left and right ends of the main ultraviolet irradiation part. Both the main ultraviolet irradiation part and the secondary ultraviolet irradiation part include a trough-shaped outer shell and a lamp cover that matches the outer shell, and the cross-section of the lamp cover is bow-shaped.

[0006] Preferably, the lamp tube holder includes lamp heads located at both ends of the outer shell trough. The lamp heads are triangular in shape. A reflector is installed on the inclined side surface of the lamp head near the air inlet end. One end of the reflector is installed at the top of the air inlet and forms an angle of 20 - 30 degrees with the air inlet. The reflector extends downward along the side surface of the lamp head to two-thirds of the air inlet and then deflects 15 - 30 degrees toward the air inlet side, and then continues to extend to the end of the air inlet along the deflected angle. A top reflector in an M shape is installed on the reflector.

[0007] Preferably, the top reflector includes a left reflector and a right reflector arranged symmetrically. The symmetry plane passes through the center line of the ultraviolet lamp tube and is along the plumb line direction. The left reflector and the right reflector are dielectric film reflectors.

[0008] Preferably, the auxiliary ultraviolet irradiation part includes a left auxiliary ultraviolet irradiation part and a right auxiliary ultraviolet irradiation part with the same structure. A secondary hinge plate is installed at the lower end of the housing of the auxiliary ultraviolet irradiation part. An air outlet hole penetrating its inside and outside is opened at the bottom of the groove of the housing of the auxiliary ultraviolet irradiation part. An installation plate fixedly connected to the top reflector is provided at the air outlet hole, and a Venturi tube is formed by the gap between the ultraviolet lamp tube and the lamp cover.

[0014] The present invention has the following beneficial effects for the prior art: The present invention drives the ultraviolet module by a trailer to heat the building waterproof coating, with a fast construction speed. By dividing the ultraviolet module into three parts, it is convenient for storage. Lampshades are installed on the main and auxiliary ultraviolet irradiation parts, which not only prevent rain from getting wet but also form a Venturi tube with the ultraviolet lamp tube group, accelerating the entry of external air into the interior of the auxiliary ultraviolet irradiation part and achieving a good cooling effect. The present invention guides the light above the ultraviolet lamp tube to the lower part of the ultraviolet lamp tube through the reflector and the top reflector, improving the utilization rate of the energy released by the ultraviolet lamp tube.

Specific embodiments

[0024] To make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below in conjunction with embodiments and the accompanying drawings. The illustrative embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0025] Embodiment 1

[0026] As Figure 1-7 shown, a building coating heating device, a lifting module 3 is provided at the left end of the trailer 1, and the lifting module 3 is connected to the ultraviolet module 4 through a mounting bracket provided on its left side; the ultraviolet module 4 includes a main ultraviolet irradiation part 401 connected to the mounting bracket, and also includes two auxiliary ultraviolet irradiation parts hinged to the left and right ends of the main ultraviolet irradiation part 401; both the main ultraviolet irradiation part 401 and the auxiliary ultraviolet irradiation part include a trough-shaped housing and a lamp cover 406 cooperating with the housing, the lamp cover 406 protrudes downward, and the cross-section of the lamp cover 406 is in a bow shape.

[0027] Air inlets 411 are provided on the front and rear trough edges of the housing, and an ultraviolet lamp tube group 410 connected to the trailer 1 is provided inside the housing. The ultraviolet lamp tube group 410 includes a group of lamp tube holders connected to the housing, and two parallel ultraviolet lamp tubes 416 are installed between the lamp tube holders.

[0028] The lamp tube holder includes lamp heads 415 at both ends located in the housing groove. The lamp heads 415 are triangular. A reflector 414 is installed on the inclined side of the lamp head 415 near the air inlet 411 end. One end of the reflector 414 is installed at the top of the air inlet 411 and the included angle with the air inlet 411 is 20 - 30 degrees. The reflector 414 extends downward along the side of the lamp head 415 to two-thirds of the air inlet 411 and then deflects 15 - 30 degrees toward the side close to the air inlet 411, and then continues to extend to the end of the air inlet 411 along the deflected angle. A top reflector 417 in an M shape is installed on the reflector 414.

[0029] The top reflector 417 includes a left reflector and a right reflector arranged symmetrically. The symmetry plane passes through the center line of the ultraviolet lamp tube 416 and is along the plumb line direction. The left reflector and the right reflector are dielectric film reflectors.

[0030] The auxiliary ultraviolet irradiation part includes a left auxiliary ultraviolet irradiation part 402 and a right auxiliary ultraviolet irradiation part 403 with the same structure. A sub-hinged plate 404 is installed at the lower end of the housing of the auxiliary ultraviolet irradiation part. An air outlet hole 412 penetrating inside and outside is opened at the bottom of the groove of the housing of the auxiliary ultraviolet irradiation part. An installation plate fixedly connected to the top reflector 417 is provided at the air outlet hole 412. The gap between the ultraviolet lamp tube and the lamp cover 406 forms a Venturi tube.

[0031] A group of symmetrically arranged hydraulic rods 407 are installed on the upper end face of the housing of the main ultraviolet irradiation part 401, and a main hinged plate 405 cooperating with the sub-hinged plate 404 is also installed.

[0032] One end of the hydraulic rod 407 is installed with a Y-shaped connecting rod 409. The long end of the Y-shaped connecting rod 409 is hinged to the main hinged plate 405, and the short end of the Y-shaped connecting rod 409 is hinged with a sub-hinged rod 408 hinged to the sub-hinged plate 404.

[0033] The trailer 1 includes a protective housing and also includes a hydraulic module 2 cooperating with the hydraulic rod 407.

[0034] A reflective film is provided on the inner side surface of the housing. The reflector 414 is fixedly connected to the top reflector 417 at the bent part. A dielectric film reflector is installed on the inner side surface of the reflector 414.

[0035] An antireflection film 413 is provided on the inner side surface of the lamp cover 406.

[0036] In this embodiment, the working state of the hydraulic module 2 is controlled by the control button on the trailer 1. When it is necessary to heat and irradiate the road surface coating, the hydraulic module 2 provides pressure for the hydraulic rod 407, and the hydraulic rod 407 extends, driving the Y-shaped connecting rod 409 and the sub-hinged rod 408 to move, and unfolding the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403 from the folded state to the horizontal state. At this time, the lamp cover 406 faces the ground;

[0037] Then, the power unit of the trailer 1 provides energy for the ultraviolet lamp group 410 of the ultraviolet module. The ultraviolet lamp group 410 emits light, and then under the action of the reflector 414 and the top reflector 417, the ultraviolet rays emitted from the upper half of the ultraviolet lamp 416 are reflected to the lower part of the ultraviolet lamp 416, improving the useful work ratio of the ultraviolet lamp, saving energy. Small molecules in the coating react under the action of ultraviolet rays, and the small molecules polymerize into macromolecules to achieve the curing of the coating. By driving the trailer 1 to drive the ultraviolet module to quickly process the coating on the road surface, the efficiency is improved and the construction speed is accelerated.

[0038] During the movement of the trailer, external air enters the housing of the main ultraviolet irradiation part 401 through the air inlet 411 to cool the ultraviolet lamp group 410. When passing through the area between the ultraviolet lamp group 410 and the lamp cover 406 in the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403, the air pressure decreases, and external gas can enter the housings of the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403 faster to achieve the cooling of the ultraviolet lamp group 410.

[0039] After the construction is completed, the hydraulic module 2 contracts the hydraulic rod 407, and the moving Y-shaped connecting rod 409 and the auxiliary hinge rod 408 move to adjust the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403 from the unfolded state to the folded state. At this time, the lamp cover 406 faces the sky.

[0040] Embodiment 2

[0041] As Figure 8 shown in a building coating heating device, the lamp covers 406 of the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403 protrude upward, and an umbrella-shaped waterproof cover is installed at the air outlet 412 of the ultraviolet module 4.

[0042] The hydraulic module 2 contracts the hydraulic rod 407, and the moving Y-shaped connecting rod 409 and the auxiliary hinge rod 408 move to adjust the left auxiliary ultraviolet irradiation part 402 and the right auxiliary ultraviolet irradiation part 403 from the unfolded state to the folded state. The lamp cover 406 faces the sky. At this time, the lamp cover 406 is equivalent to a concave lens, and under the sunlight irradiation, it is scattered by the lamp cover 406 and irradiates into the housing, which is convenient for protecting the internal equipment.

[0043] The above are only the preferred embodiments of the present invention, only for explaining the solutions and effects of the present invention, and cannot be considered as limiting the implementation scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made, and all should still fall within the patent coverage of the present invention.
