Description

Technical Field

[0001] This utility model relates to the field of asphalt testing technology, specifically a road asphalt testing device. Background Technology

[0002] Road asphalt testing refers to the process of conducting a series of physical, chemical, and performance tests and analyses on asphalt materials and their mixtures used for paving highways, airport runways, and other traffic surfaces. Its fundamental purpose is to ensure the quality, durability, and safety of asphalt pavement projects, thereby extending the service life of roads and reducing the overall life-cycle maintenance costs.

[0003] The softening point test of asphalt is a relatively important item, which reflects the heat resistance and high-temperature stability of asphalt. The higher the softening point, the better the high-temperature performance of asphalt, and the less likely it is to soften under the high temperature of summer. The softening point test of asphalt is generally carried out by heating water using the sphere method. In actual testing, asphalt will adhere to the surface of the test ball, and the subsequent cleaning work is cumbersome, which is inconvenient in actual testing. Utility Model Content

[0004] The purpose of this invention is to provide a road asphalt testing device to solve the problem mentioned in the background art that the asphalt softening test is generally carried out by heating water in the sphere using the sphere-ball method. In actual operation, the asphalt will adhere to the surface of the testing ball, and the subsequent cleaning work is cumbersome, which is inconvenient in actual testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a road asphalt testing device, comprising a base plate and a fixed rod fixedly installed on the upper side of the base plate. A movable component is installed on the upper side of the fixed rod. The movable component includes a fixed plate fixedly installed on the side of the fixed rod. Sliding rods are fixedly installed on both sides of the fixed plate. A movable plate is slidably installed on both sliding rods. A clamping groove is formed on the fixed plate. A power supply module is fixedly installed on the side of the movable plate. A water tank is formed inside the movable plate. An electric heating tube is fixedly installed on the side of the power supply module. The power supply module is electrically connected to the electric heating tube. A limit component is installed on the upper end of the movable plate. A water tank is fixedly installed on the upper end of the base plate. The water tank is located at the lower end of the clamping groove.

[0006] Preferably, a limiting plate is fixedly installed on the upper ends of the two slide rods, and a spring is sleeved on each slide rod, with the spring positioned between the limiting plate and the movable plate.

[0007] Preferably, the limiting plate has a slot in the middle, and the limiting component includes a movable block fixedly installed on the upper end of the movable plate, the movable block being slidably connected in the slot.

[0008] Preferably, each of the movable blocks has a mounting groove on both sides, and a slider is slidably connected in each mounting groove. An arc-shaped block is fixedly installed on the side of each slider, and a spring is fixedly installed between the inner wall of the slider and the inner wall of the mounting groove.

[0009] Preferably, a thermometer is fixedly installed on the side wall of the fixed rod, and a heat-conducting block is fixedly installed on the upper end of the thermometer. The heat-conducting block is disposed on the side of the movable plate.

[0010] Preferably, an infrared detector is fixedly installed on the lower side of the fixing plate, and the detection end of the infrared detector is located on the lower side of the clamping groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Place the asphalt to be processed into the clamping groove, release the limit on the movable plate, and clamp the asphalt to be tested in the clamping groove.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figure 1 - Figure 3 A road asphalt testing device includes a base plate 1 and a fixed rod 2 fixedly installed on the upper side of the base plate 1. A movable component 4 is installed on the upper side of the fixed rod 2. The movable component 4 includes a fixed plate 41 fixedly installed on the side of the fixed rod 2. Sliding rods 44 are fixedly installed on both sides of the fixed plate 41. A movable plate 42 is slidably installed on the two sliding rods 44. A clamping groove 47 is opened on the fixed plate 41. A power supply module 43 is fixedly installed on the side of the movable plate 42. A water tank 48 is opened inside the movable plate 42. An electric heating tube 49 is fixedly installed on the side of the power supply module 43. The power supply module 43 is electrically connected to the electric heating tube 49. A limit component 5 is installed on the upper end of the movable plate 42. A water tank 3 is fixedly installed on the upper end of the base plate 1. The water tank 3 is located at the lower end of the clamping groove 47.

[0017] In this embodiment: When using this device for asphalt softening test, the movable plate 42 can first be pulled and fixed to the upper end of the fixed plate 41 by the limiting component 5, and the asphalt to be processed can be placed into the clamping groove 47. Then, the limiting component 5 is used to release the limiting of the movable plate 42, and the movable plate 42 slides down along the slide rod 44. The movable plate 42 clamps and limits the asphalt to be tested placed in the clamping groove 47. At this time, the power supply module 43 can be used to heat the heating tube 49. The heating tube 49 heats the water in the water tank 48, and the heated water clamps the movable plate 42. The asphalt block at the bottom is heated, and as the temperature gradually increases, the temperature of the asphalt block becomes higher and higher. When the asphalt softens and falls due to the heat, it can be caught by the water tank 3 set at the bottom. When this road asphalt detection device is in use, it heats the water in the water tank 48 through the electric heating tube 49 and then heats the asphalt indirectly. The asphalt in contact is heated evenly, and the heating from the top allows the asphalt to fall freely into the water tank 3 for collection when it softens and falls. Compared with the traditional direct heating method, the heating is more even and facilitates subsequent cleaning work.

[0018] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 2 - Figure 4 The upper ends of the two slide rods 44 are fixedly installed with a limiting plate 45. A spring 46 is sleeved on each slide rod 44. The spring 46 is located between the limiting plate 45 and the movable plate 42. The spring 46 can push the movable plate 42 downward naturally to hold it in place.

[0019] The limiting plate 45 has a slot 451 in the middle, and the limiting component 5 includes a movable block 51 fixedly installed on the upper end of the movable plate 42. The movable block 51 is slidably connected in the slot 451.

[0020] The movable block 51 has mounting grooves 52 on both sides, and sliders 53 are slidably connected in the mounting grooves 52. Arc-shaped blocks 54 are fixedly installed on the sides of the sliders 53. A second spring 55 is fixedly installed between the inner wall of the slider 53 and the inner wall of the mounting groove 52. The second spring 55 provides an outward pushing force to the slider 53. When moving upward, the arc-shaped blocks 54 can be automatically squeezed and slid into the interior of the mounting groove 52.

[0021] A thermometer 6 is fixedly installed on the side wall of the fixed rod 2. A heat-conducting block 61 is fixedly installed on the upper end of the thermometer 6. The heat-conducting block 61 is located on the side of the movable plate 42 and is in contact with the side of the movable block 42. When the water tank 48 inside the movable block 42 is heated, the heat-conducting block 61 can be heated at the same time, and its actual temperature can be observed through the thermometer 6.

[0022] An infrared detector 7 is fixedly installed on the lower side of the fixing plate 41. The detection end of the infrared detector 7 is located on the lower side of the clamping groove 47. The infrared detector 7 can detect the time of asphalt melting and dripping and the temperature displayed by the thermometer 6 at that time.

[0023] In this embodiment: When using this device for asphalt softening test, the movable plate 42 can be pulled upwards first. During the pulling process, the movable block 51 slides upwards along the slot 451. As the movable block 51 moves upwards, the arc-shaped block 54 on the side contacts the side wall of the slot 451 and is squeezed and slid into the mounting groove 52 by the slot 451 during the upward push until the arc-shaped block 54 and the slider 53 are completely pushed into the mounting groove 52. During the continued upward movement, the arc-shaped block 54 disengages from the limit of the slot 451 and is automatically pushed outwards under the action of the spring 55, fixing and limiting the movable block 51 and the movable plate 42. Then, the asphalt block to be tested can be placed into the clamping groove 47, and the arc-shaped block 54 is pushed and slid. Inside the mounting slot 52, the movable plate 42 is automatically pushed downward by the spring 46 to clamp and fix the asphalt block to be tested in the clamping slot 47. Then, the water in the water tank 48 can be heated by the electric heating tube 49, which indirectly heats the asphalt to be tested. When heated by the water tank 48, the side contacts the heat-conducting block 61. The temperature of the heat-conducting block 61 can be detected by the thermometer 6. When the asphalt is heated to the point of melting and falling, the real-time temperature at the time of falling can be detected by the infrared detector 7. When the device is in use, the clamping slot 47 can be opened or closed by the cooperation of the limiting component 5 and the movable plate 42. The operation is simple. The spring 46 can automatically clamp the asphalt to be tested in the clamping slot 47 when the limiting component 5 is at the lower end of the limiting plate 45.
