Abstract
Description
Technical Field
[0001] This utility model relates to the field of asphalt construction technology, and in particular to a rapid drying device for asphalt pavement. Background Technology
[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials into mineral materials. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors, making the pavement smooth, dust-free, impermeable, and durable. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction.
[0003] Chinese patent document CN211340341 U discloses a heating device for full-thickness repair of asphalt pavement, including a frame, a first base box fixedly installed at the bottom of the frame, and a first pneumatic cylinder fixedly installed at the top of the frame. The bottom end of the first pneumatic cylinder passes through the frame and the first base box and extends into the interior of the first base box, where a movable plate is fixedly installed. This heating device for full-thickness repair of asphalt pavement utilizes a first pneumatic cylinder, a heating roller, a hot air blower, and a nozzle. The hot air blower generates a hot airflow, which passes through a vertical pipe, a through pipe, and a horizontal pipe before being sprayed out from the nozzle, thus performing preliminary drying of the crack sealant in the asphalt pavement. The operation of the first pneumatic cylinder causes the heating roller to move downwards, further compacting and drying the crack sealant, thereby increasing the drying speed of the sealant and enhancing the practicality of the device.
[0004] The existing technology has the following problems:
[0005] The device directly uses a hot air blower to draw in air for heating. However, the air environment around asphalt construction usually contains a lot of dust, which can cause blockage inside the hot air blower over a long period of time. Therefore, the dust filter needs to be replaced frequently. However, the hot air blower does not have a structure for quick disassembly and assembly of the dust filter, making it difficult to replace and install the dust filter. Utility Model Content

[0010] The air intake mechanism includes a housing, the lower side of which is fixedly connected to the upper side of the heating mechanism.

A dust removal plate is movably sleeved on the inner side of the fixed cover. Two fixed components are symmetrically distributed front and back on the flanges of the outer side of the fixed cover near the bottom and the outer side of the housing near the upper side.
[0011] Preferably, two motors are fixedly connected to the upper side of the substrate near the left and right sides, which are symmetrically distributed. The output ends of the two motors are fixedly connected to winding wheels, and the winding wheels are distributed in an isosceles triangle. The inner sides of the three winding wheels are wound with traction belts, and the lower sides of the traction belts are fixedly connected to the left and right sides of the mounting frame.
[0012] Preferably, the upper side of the mounting bracket is rotatably connected to three isosceles triangularly distributed limiting rods. The outer sides of the two limiting rods on the left side are movably sleeved in the limiting holes on the lower side of the substrate near the left side. The upper end of the limiting rod on the right side is slidably connected to two sliding frames symmetrically distributed on the front and rear substrates. The upper side of the sliding frame is fixedly connected to the lower middle part of the substrate.
[0013] Preferably, the fixing component includes a U-shaped sleeve. The outer side of the U-shaped sleeve is movably fitted onto the outer side of the first flange near the upper side of the outer side of the outer side of the outer side of the mechanism housing and the outer side of the second flange near the bottom side of the outer side of the fixing cover. Two symmetrically distributed insert rods are movably fitted onto the upper ends of the U-shaped sleeve, and the outer sides of the insert rods are simultaneously movably fitted into the insertion holes on the ground flange and the second flange. Vertical rods are movably fitted onto the inner sides of the two insert rods. A retaining plate is fixedly connected to the lower side of the two vertical rods, and the outer side of the retaining plate is movably fitted into the limiting groove opened on the lower side of the U-shaped sleeve. A top plate is fixedly connected to the outer side of the two vertical rods, and the outer side of the top plate is movably fitted onto the inner side of the insert rods.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figures 1-5 As shown, an asphalt pavement rapid drying device includes a base plate 1, a rolling wheel 2 rotatably connected to the lower side of the base plate 1 near the left side, a support wheel 3 movably installed on the lower side of the base plate 1 near the right side, a heating mechanism 4 movably installed in the middle of the upper side of the base plate 1, a blower mechanism 5 movably sleeved on the lower side of the base plate 1, an air intake mechanism 6 fixedly connected to the upper side of the heating mechanism 4, and a traction hook 7 fixedly connected to the middle of the right side of the base plate 1.
[0028] The blower mechanism 5 includes a mounting bracket 51. Several evenly distributed hot air nozzles 52 are fixedly connected to the upper side of the mounting bracket 51 near the edge. The hot air nozzles 52 are arranged in an isosceles triangle shape. A vent pipe 53 is fixedly connected between the upper side of the hot air nozzles 52 and the lower side of the heating mechanism 4.
[0029] The air intake mechanism 6 includes a housing 61. The lower side of the housing 61 is fixedly connected to the upper side of the heating mechanism 4. An air intake fan 62 is fixedly sleeved on the inner side of the housing 61 near the upper side. A fixed cover 63 is movably sleeved on the outer side of the housing 61 near the upper side. A dust removal plate 64 is movably sleeved on the inner side of the fixed cover 63. Two fixed components 65 are symmetrically distributed front and back on the flanges of the outer side of the fixed cover 63 near the bottom and the outer side of the housing 61 near the upper side.
[0030] It should be noted that the heating mechanism 4 can heat the air. The heated air is distributed to each hot air nozzle 52 through the ventilation pipe 53, and then the hot air nozzles 52 are used to dry the road surface. At the same time, since the hot air nozzles 52 are arranged in a triangular pattern, they can blow road debris such as fallen leaves to the front and back sides, preventing the fallen leaves from sticking to the road surface. The air intake fan 62 drives the air to flow from top to bottom. The dust removal plate 64 absorbs the dust in the air passing through it. The fixing cover 63 and the fixing component 65 fix the dust removal plate 64.
[0031] like Figure 3 As shown, two motors 54 are fixedly connected to the upper side of the substrate 1 near the left and right sides. The output ends of the two motors 54 are fixedly connected to winding wheels 55, and the winding wheels 55 are distributed in an isosceles triangle. The inner sides of the three winding wheels 55 are all wound with traction belts 56, and the lower side of the traction belts 56 is fixedly connected to the left and right sides of the mounting bracket 51.
[0032] It should be noted that the motor 54 drives the winding wheel 55 to rotate. When the winding wheel 55 rotates, the traction belt 56 tightens or extends on the winding wheel 55, causing the mounting frame 51 to move up and down.
[0033] like Figure 3 As shown, the upper side of the mounting bracket 51 is rotatably connected to three isosceles triangularly distributed limiting rods 57. The outer sides of the two limiting rods 57 on the left side are movably sleeved in the limiting holes on the lower side of the substrate 1 near the left side. The upper end of the limiting rod 57 on the right side is slidably connected to two sliding frames 58 symmetrically distributed on the front and rear substrates 1. The upper side of the sliding frame 58 is fixedly connected to the lower middle part of the substrate 1.
[0034] It should be noted that the left limiting rod 57 always remains vertical, which is used to limit the relative position of the left and right sides of the mounting bracket 51. The three limiting rods 57 cooperate with each other to limit the relative position of the front and rear sides of the mounting bracket 51.
[0035] like Figure 5As shown, the fixing component 65 includes a U-shaped sleeve 651. The outer side of the U-shaped sleeve 651 is movably sleeved on the outer side of the first flange near the upper side of the outer side of the outer side of the outer side of the outer side of the outer side of the outer side of the outer side of the fixing cover 63 near the bottom side. Two symmetrically distributed insert rods 652 are movably sleeved at both ends of the upper side of the U-shaped sleeve 651, and the outer side of the insert rods 652 are simultaneously movably sleeved in the insertion holes on the lower flange and the second flange. Vertical rods 654 are movably sleeved on the inner side of each insert rod 652. A retaining plate 653 is fixedly connected to the lower side of each vertical rod 654, and the outer side of the retaining plate 653 is movably sleeved in the limiting groove opened on the lower side of the U-shaped sleeve 651. A top plate 659 is fixedly connected to the outer side of each vertical rod 654, and the outer side of the top plate 659 is movably sleeved on the inner side of the insert rods 652. Springs 655 are movably sleeved on the inner side of each insert rod 652, and the springs 655 are located on the lower side of the top plate 659.
[0036] It should be noted that when the insertion rod 652 is movably sleeved in the insertion hole, the insertion rod 652 is fixed to the U-shaped sleeve 651, and the U-shaped sleeve 651 is fixed to the fixing cover 63, which causes the dust removal plate 64 to be fixed. The spring 655 pushes the top plate 659 upward, so that the clamping plate 653 is close to the inner side of the limiting groove. The top view projection shape of the clamping plate 653 rotates ninety degrees to match the inner shape of the insertion hole.
[0037] like Figure 5 As shown, a limiting sleeve 656 is rotatably connected to the upper side of the insertion rod 652, and the upper side locking block of the vertical rod 654 is movably sleeved inside the limiting sleeve 656.
[0038] It should be noted that the limiting sleeve 656 is used to limit the vertical rod 654, so that the limiting sleeve 656 and the vertical rod 654 cannot rotate relative to each other. At the same time, a U-shaped groove is provided on the outer side of the vertical rod 654. When the vertical rod 654 is pressed, the finger is inserted into the U-shaped groove, and the user can drive the vertical rod 654 to rotate by relying on the limiting sleeve 656.
[0039] like Figure 5 As shown, two limiting blocks 658 are fixedly connected to the upper side of the insertion rod 652, and the outer protrusion of the limiting sleeve 656 is located between the two limiting blocks 658.
[0040] It should be noted that the limit block 658 is used to limit the rotation range of the limit set 656, so that the limit set 656 skill can rotate within a 90-degree range.
[0041] like Figure 5 As shown, two ring-shaped retaining strips 657 are fixedly connected to the outer side of the insertion rod 652, and the outer side of the retaining strips 657 is movably sleeved in the vertical groove inside the insertion hole.
[0042] It should be noted that the locking strip 657 is used to restrict the insertion rod 652 and prevent the insertion rod 652 from rotating synchronously with the rotating vertical rod 654.
[0043] The working principle of this utility model is as follows: First, the intake fan 62 drives air to flow from top to bottom. The dust removal plate 64 adsorbs dust in the air passing through it. The fixing cover 63, together with the fixing component 65, fixes the dust removal plate 64. When the insertion rod 652 is movably sleeved in the insertion hole, the insertion rod 652 fixes the U-shaped sleeve 651, and the U-shaped sleeve 651 fixes the fixing cover 63, thus fixing the dust removal plate 64. The spring 655 pushes the top plate 659 upward, so that the locking plate 653 is close to the inner side of the limiting groove. The top view projection shape of the locking plate 653 rotates 90 degrees to match the inner shape of the insertion hole. The limiting sleeve 656... The retaining sleeve 656 is used to restrict the vertical rod 654, preventing relative rotation between the retaining sleeve 656 and the vertical rod 654. A U-shaped groove is provided on the outer side of the vertical rod 654. Pressing the vertical rod 654 allows a finger to be inserted into the U-shaped groove, enabling the user to rotate the vertical rod 654 using the retaining sleeve 656. Pressing and rotating the vertical rod 654 causes the insertion rod 652 to be quickly disassembled, allowing the U-shaped sleeve 651 to be removed from the outer casing 61. This removes the fixing cover 63, allowing for quick replacement and maintenance of the dust collector plate 64, preventing it from becoming clogged with dust and affecting air intake efficiency. Finally, the heating mechanism 4 heats the air, which is then distributed to each hot air nozzle 52 through the ventilation pipe 53. The hot air is then distributed from the nozzles 52 to dry the road surface. Simultaneously, because the hot air nozzles 52 are arranged in a triangular pattern, they disperse road debris such as fallen leaves, preventing them from sticking to the road surface. The motor 54 drives the winding wheel 55 to rotate. When the winding wheel 55 rotates, the traction belt 56 tightens or extends on it, causing the mounting frame 51 to move up and down. The left-side limit rod 57 remains vertical, used for... The three limiting rods 57 work together to limit the relative positions of the left and right sides of the mounting frame 51. The motor 54 drives the winding wheel 55 to rotate, causing one side of the mounting frame 51 to tilt up or the entire mounting frame 51 to rise, thereby increasing the distance between the mounting frame 51 and the hot air nozzle 52 and the ground. This prevents the device from colliding with the road surface when facing uphill or downhill sections due to the mounting frame 51 being too close to the ground. At the same time, the height of the mounting frame 51 can be freely adjusted, allowing the hot air nozzle 52 to approach the road surface and improve drying efficiency.
