Description

Technical Field

[0001] The utility model relates to the technical field of asphalt adhesion test equipment, in particular to asphalt adhesion test equipment. Background Art

[0002] Asphalt is a product of crude oil processing. At room temperature, it is a black or dark brown viscous liquid or solid. It is widely used in road engineering. The adhesion test of asphalt and coarse aggregate is used to test the adhesion of asphalt to the surface of coarse aggregate and evaluate the water stripping resistance of coarse aggregate.

[0003] The existing asphalt adhesion test mainly immerses the aggregate into heated asphalt after drying, puts it into boiling water after cooling, takes it out after immersion, observes the degree of peeling, and evaluates its adhesion. Most of the existing asphalt adhesion test methods are to manually put the coarse aggregate into a heating tank so that the surface of the coarse aggregate is coated with asphalt, and then put it into water for boiling. This makes the degree of coating of each coarse aggregate with asphalt and the degree of boiling in water different due to human factors, which will lead to large errors in evaluating the adhesion level of asphalt and coarse aggregate. In addition, it is easy to scald the staff during the process of putting it in, and the work efficiency will be greatly reduced. For this reason, we propose an asphalt adhesion test equipment.

There is no need to manually carry them into the heating tank, which reduces the harm to workers during the test and improves the overall work efficiency. It can also compare multiple groups of asphalt and coarse aggregate, and more intuitively observe the adhesion of asphalt. It is more accurate in assessing the adhesion level of asphalt and coarse aggregate, etc., which can effectively solve the problems in the background technology.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

By setting the temperature controller 2, we can conveniently control the temperature in the heating tank body 1.

[0022] Furthermore, the lifting assembly 6 includes a cylinder 7, a through hole 1 8, a piston rod 9, a connecting block 10, a connecting plate 11, a connecting rod 12, a conical tray 13, and a through hole 2 14. The number of the conical tray 13 and the through hole 2 14 are eight groups. The cylinder 7 is fixedly mounted on the outer surface of the middle part of the upper end of the top plate 5. By setting the cylinder 7, we can conveniently drive the piston rod 9 to move up and down.

[0023] Furthermore, a through hole 8 is opened on the outer surface of the middle part of the upper end of the top plate 5, and a piston rod 9 is fixedly installed on the outer surface of the lower end of the cylinder 7, and the piston rod 9 is passed through the outer surface of the lower end of the top plate 5. Through the set through hole 8, when the piston rod 9 moves up and down, it is more convenient and will not affect the fixation of the cylinder 7.

[0024] Furthermore, a connecting block 10 and a connecting plate 11 are fixedly installed on the outer surface of one end of the lower end of the piston rod 9, and the connecting block 10 is located on the outer surface of the middle part of the upper end of the connecting plate 11. Through the setting of the connecting block 10, we can conveniently fix the piston rod 9 and the connecting plate 11 together.

[0025] Furthermore, a connecting rod 12 and a conical tray 13 are fixedly installed on the outer surface around the lower end of the connecting plate 11, and the connecting rod 12 is located on the outer surface around the upper end of the conical tray 13. Through the setting of the conical tray 13, we can quickly place the coarse aggregate in the heating tank body 1.

[0026] Furthermore, a through hole 14 is provided on the outer surface of the middle part of the upper end of the conical tray 13. Through the through hole 14, when the coarse aggregate is taken out from the heating tank body 1, the asphalt and moisture remaining on the surface will flow into the heating tank body 1 along with the through hole, so that we can better observe the adhesion of asphalt on the coarse aggregate.

[0027] How it works

[0028] First, the water temperature in the heating tank body 1 is heated to a certain temperature through the temperature controller 2, and the coarse aggregate is placed in the conical tray 13. The cylinder 7 is started through the provided lifting assembly 6. Under the action of the cylinder 7, the piston rod 9 is driven to move downward, and the connecting plate 11 at the lower end of the piston rod 9 will also move downward. The conical trays 13 with multiple groups fixed at the lower end of the connecting plate 11 will descend into the heating tank body 1, so that multiple groups of dried coarse aggregates can be put into the heating tank body 1 one by one for adhesion test at the same time, without the need to manually carry them into the heating tank body 1, thereby reducing the risk of injury to the staff during the insertion, improving the overall work efficiency, and comparing multiple groups of asphalt and coarse aggregate, so that the adhesion of asphalt can be observed more intuitively, and the adhesion level of asphalt and coarse aggregate can be assessed more accurately.
