Technical Field

[0001] The utility model relates to the technical field of asphalt heating equipment, in particular to an asphalt heating device for highway construction. Background Technique

[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid, in a liquid state, black on the surface, soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementing material. In highway construction, people often need to use asphalt. Asphalt has a wide range of uses and is particularly essential in highway construction. During construction, people need to constantly prevent asphalt from drying and solidifying into blocks, and thus need to continuously heat and stir the asphalt. In the prior art, when using asphalt in highway construction, the valve is opened to discharge the asphalt. Since the discharge port is fixed, it is inevitable to encounter the need to turn the discharge port during construction. When in use, the entire device needs to be turned around, which is rather inconvenient and lacks the function of arbitrarily adjusting the position of the asphalt discharge port.

[0003] For example, an asphalt heating device for highway construction disclosed in the authorized patent document with the application number CN202123000679.9 includes a tank body, a rotating shaft rotatably connected in the tank body along the vertical direction, a screw blade fixedly connected to the rotating shaft, a driving motor fixedly installed on the top surface of the outer wall of the tank body and connected to the rotating shaft.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an asphalt heating device for highway construction, including: a base 1, and a barrel 3 provided with a heating rod 2 on the top of the base 1; a discharge valve pipe 4 is communicated with the surface of the barrel 3; a sealing cover 5 is installed on the top of the barrel 3; a mixing member 6 for stirring the asphalt in the barrel 3 is arranged inside the sealing cover 5; an adjusting member 7 for rotating the barrel 3 is arranged on the top of the base 1.

[0024] The adjusting member 7 includes a cylinder 71 rotatably installed inside the base 1. The top of the cylinder 71 is fixedly installed with the bottom of the barrel 3. A plurality of pulleys 72 are installed at the bottom of the barrel 3, and the bottoms of the plurality of pulleys 72 are in contact with the top of the base 1. A limiting member 70 for fixing the barrel 3 is provided at the top of the base 1.

[0025] The limiting member 70 includes a fixed toothed ring 701 fixedly installed at the bottom of the barrel 3. The top of the base 1 is provided with a movable toothed ring 702 through four springs 703, and the top of the movable toothed ring 702 is meshed with the bottom of the fixed toothed ring 701;

[0026] In this embodiment, when asphalt paving is carried out in road construction, the asphalt in the barrel 3 is discharged through the discharge valve pipe 4. When asphalt needs to be filled in different places, the barrel 3 can be rotated and adjusted. Two cylinders 9 can be started to drive two pressing plates 10 to press down. The two pressing plates 10 move the movable toothed ring 702 downward, so that the movable toothed ring 702 is not in contact with the fixed toothed ring 701. The barrel 3 can be rotated to drive the pulleys 72 at its bottom to slide on the base 1 to adjust the discharging direction of the discharge valve pipe 4. In the normal state, the spring 703 meshes the movable toothed ring 702 with the fixed toothed ring 701 to limit the barrel 3.

[0027] A plurality of sliding rods 8 are movably sleeved inside the movable toothed ring 702. The bottoms of the plurality of sliding rods 8 are fixedly installed on the top of the base 1, and the surfaces of the sliding rods 8 are movably sleeved with the inside of the movable toothed ring 702;

[0028] Specifically, the surface of the sliding rod 8 is slidably installed inside the movable toothed ring 702 to enhance the stability of the movement of the movable toothed ring 702.

[0029] Two cylinders 9 are embedded in the top of the base 1. The tops of the two cylinders 9 are fixedly installed with pressing plates 10, and the two pressing plates 10 are both arranged on the top of the movable toothed ring 702;

[0030] The two cylinders 9 are synchronous cylinders 9. Starting the cylinders 9 drives the pressing plate to move the movable toothed ring 702 downward, realizing the separation of the movable toothed plate and the fixed toothed plate. At the same time, when the barrel 3 rotates forcibly, the rotation of the fixed toothed plate will drive the movable toothed plate to move downward and compress the spring 703, which can also realize the rotation of the barrel 3, but it is more laborious.

[0031] In order to have a guiding effect on the rotation of the plurality of pulleys 72, an annular groove 11 for the plurality of pulleys 72 to slide is opened at the top of the base 1.

[0032] The mixing member 6 includes a motor 61 fixedly installed on the top of the sealing cover 5. The output end of the motor 61 penetrates the bottom of the sealing cover 5 and is installed with a stirring paddle 62;

[0033] Among them, starting the motor 61 drives the stirring paddle 62 at the output end to rotate, and continuously stirs the asphalt in the cylinder.

[0034] A ring-shaped cover 12 is fixedly installed on the surface of the barrel body 3, and several heating screw rods 13 are installed inside the ring-shaped cover 12;

[0035] Specifically, a ring-shaped cover 12 is installed outside the barrel body 3, and several heating screw rods 13 are arranged inside the ring-shaped cover 12 to heat-treat the inside of the barrel body 3. The ring-shaped cover 12 is a heat-insulating cover to reduce heat loss.

[0036] In order to prevent the barrel body 3 from rotating too much, two limit posts 15 are provided to limit the rotation angle of the barrel body 3. At the same time, a handle 14 is installed to facilitate the rotation of the barrel body 3. An anti-scalding cylinder is installed on the handle 14. A handle 14 is fixedly installed on one side of the barrel body 3, and two limit posts 15 are fixedly installed on the top of the base 1.

[0037] When the device is used for asphalt paving in highway construction, the asphalt in the barrel body 3 is discharged through the discharge valve pipe 4. When asphalt needs to be filled in different places, the barrel body 3 can be rotated and adjusted. Two cylinders 9 can be started to drive two pressing plates 10 to press down. The two pressing plates 10 drive the movable gear ring 702 to move downward, so that the movable gear ring 702 is not in contact with the fixed gear ring 701. The barrel body 3 can be rotated to drive the bottom pulley 72 to slide on the base 1 to adjust the discharge direction of the discharge valve pipe 4. In the normal state, the spring 703 meshes the movable gear ring 702 with the fixed gear ring 701 to limit the barrel body 3. The two cylinders 9 are synchronous cylinders 9. Starting the cylinders 9 drives the pressure plate to move the movable gear ring 702 downward to separate the movable gear plate from the fixed gear plate. At the same time, when the barrel body 3 rotates forcibly, the rotation of the fixed gear plate will drive the movable gear plate to move downward and compress the spring 703, which can also realize the rotation of the barrel body 3, but it is more laborious. A ring-shaped cover 12 is installed outside the barrel body 3, and several heating screw rods 13 are arranged inside the ring-shaped cover 12 to heat-treat the inside of the barrel body 3. The ring-shaped cover 12 is a heat-insulating cover to reduce heat loss.

[0038] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
