DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] The embodiment of the present invention provides a thermal insulation film coating device for highway construction: Embodiment 1, as Figure 1-6 As shown, it includes a traction frame 1, a placing rod 2 is fixedly installed at the front end of the traction frame 1, a sleeve 28 is fixedly installed above the front end of the traction frame 1, a limiting sleeve 3 is fixedly installed at the bottom end of the sleeve 28, and the bottom end of the limiting sleeve 3 is rotatably connected to the main pressure wheel 4, and an extension rod 5 is slidably connected inside the sleeve 28. A groove is provided at one end of the extension rod 5 located inside the sleeve 28, and the size of the groove is the same as the size of the fixed magnetic plate 13 at the front end of the sliding rod 12. Through such an arrangement, the sliding rod 12 can be connected to the extension rod 5 as one after being squeezed.

[0024] A support frame 6 is fixedly installed at one end of the extension rod 5 away from the sleeve 28, and the support frame 6 and the limit sleeve 3 are fixedly connected by a tension spring 18. Auxiliary extrusion wheels 7 are arranged on both sides of the bottom end of the support frame 6, and a limit rod 8 is fixedly installed at the front end of the support frame 6. A sliding rheostat 10 is inlaid on the upper surface of the limit rod 8. The limit sleeve 3 is slidably connected to the outer surface of the limit rod 8, and a block 15 adapted to the sliding rheostat 10 is fixedly installed inside the limit sleeve 3. A fixed frame 11 is fixedly installed at the bottom end of the limit sleeve 3, and the main pressure wheel 4 is rotatably connected to the inner side of the fixed frame 11. A sliding rod 12 is provided, one end of the sliding rod 12 extends to the interior of the support frame 6, one end of the sliding rod 12 is located inside the sleeve 28, and the extension rod 5 and the end of the sliding rod 12 located inside the sleeve 28 are fixedly installed with a fixed magnetic plate 13, the magnetism of the fixed magnetic plate 13 at the front end of the sliding rod 12 is greater than the magnetism of the fixed magnetic plate 13 at the front end of the extension rod 5, and the size of the fixed magnetic plate 13 at the front end of the extension rod 5 is the same as the inner size of the sleeve 28. Through such an arrangement, it can be ensured that the extension rod 5 can move outward under a smaller repulsive force, and when the magnetism of the electromagnet 14 increases, it can squeeze the sliding rod 12 to make the sliding rod 12 move.

[0025] An electromagnet 14 is fixedly installed inside the sleeve 28, and the electromagnet 14 is electrically connected to the sliding rheostat 10. A groove 25 is opened on the side of the limit rod 8. A fixed plate 26 is fixedly installed on the inner side wall of the limit sleeve 3. A rotating plate 27 is hinged in front of the fixed plate 26 inside the limit sleeve 3. An extrusion switch 9 is fixedly installed between the fixed plate 26 and the rotating plate 27 inside the limit sleeve 3. The extrusion switch 9 is connected in series with the sliding rheostat 10. The rotating plate 27, the fixed plate 26 and the extrusion switch 9 are slidably connected inside the groove 25. Through such an arrangement, it can be ensured that the limit sleeve 3 can squeeze the extrusion switch 9 during the forward movement, and the limit rod 8 can be moved forward during the forward movement. During the process, the squeezing switch 9 is not squeezed, and finally the voltage of the electromagnet 14 does not increase during the forward movement of the support frame 6. The initial voltage is retained in the circuit of the sliding rheostat 10 and the electromagnet 14. The adjustment end of the sliding rheostat 10 and the switch end of the circuit are in contact with and clamped with the block 15. When the adjustment end moves to the maximum amount, the block 15 slides forward for a distance. When the block 15 is separated from the sliding rheostat 10, the sliding rheostat 10 is short-circuited, and the voltage of the electromagnet 14 is instantly reduced. Under the action of the tension spring 18, the block 15 contacts the sliding rheostat 10 and adjusts to the minimum value. However, during this process, the squeezing switch 9 is opened and the sliding rheostat 10 is disconnected. The cross-sectional shape of the groove 25 is a trapezoid, and the front end depth of the groove 25 is less than the rear end depth of the groove 25. Such a setting can increase the friction force, thereby enabling the rotating plate 27 to be squeezed.

[0026] A baffle 16 is fixedly installed on the outer surface of the sliding rod 12 located inside the extension rod 5, and the baffle 16 and the inner wall of the extension rod 5 are fixedly connected by a reset spring 17. A sliding groove 19 is opened inside the support frame 6, and a support spring 20 is fixedly installed inside the sliding groove 19. A sliding frame 21 is fixedly installed on the upper surface of the support spring 20. An extrusion block 22 is fixedly installed at one end of the sliding rod 12 located inside the sliding groove 19. The extrusion block 22 is located above the sliding frame 21 and is in extrusion contact with the sliding frame 21. Both sides of the bottom end of the sliding frame 21 extend from the bottom end of the support frame 6 to the outside of the support frame 6. Support frames 23 are fixedly installed at both ends of the bottom of the support frame 6. The auxiliary extrusion wheel 7 is rotatably connected to the inside of the support frame 23. A friction half ring 24 is slidably connected to the inside of the support frame 23. The friction half ring 24 is sleeved on the outer surface of the central axis of the auxiliary extrusion wheel 7. The sliding frame 21 is fixedly connected to the friction half ring 24, and the sliding frame 21 is slidably connected to the support frame 23. The cross-sectional shape of the sliding frame 21 is an "inside" shape, the cross-sectional shape of the sliding groove 19 is an "inside" shape, and the width of the crossbeam portion of the sliding groove 19 is greater than the width of the crossbeam portion of the sliding frame 21. This arrangement ensures that the sliding frame 21 can adapt to the shape of the support frame 6, so that the auxiliary extrusion wheels 7 on both sides can be controlled at the same time.

[0027] When in use, the thermal insulation film is placed on the placement rod 2, and the thermal insulation film can be laid by pulling the traction frame 1. During the movement, the electromagnet 14 is energized so that the fixed magnetic plate 13 is repelled and moves outward, and at the same time, the limiting sleeve 3 slides relative to the sliding rheostat 10, thereby enhancing the magnetism of the electromagnet 14, pushing the sliding rod 12 outward and limiting the auxiliary extrusion wheel 7 by squeezing it, so that the auxiliary extrusion wheel 7 cannot rotate. During the movement, the main pressure wheel 4 can squeeze the thermal insulation film from the middle, thereby expelling the air to both sides. When the limiting sleeve 3 moves to the front end and does not contact the sliding rheostat 10, the electromagnet 14 restores its initial magnetism. At this time, under the action of the tension spring 18, the thermal insulation film is squeezed from the rear of the auxiliary extrusion wheel 7 on both sides.

[0028] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
