Technical Field

[0002] In the field of asphalt material quality detection, the penetration test and wear resistance detection are two key links for evaluating the quality of asphalt. The penetration test measures the depth of a standard needle penetrating an asphalt specimen within a certain weight and time to reflect the hardness, consistency, and shear failure resistance of the asphalt, which is one of the important indicators for evaluating the road performance of asphalt.

[0033] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0034] As recorded in the background art, in the prior art, the functions of the detection device are relatively single, so that the penetration test and wear resistance detection often rely on two completely different devices, increasing the number of devices and being not conducive to use.

[0035] To solve this technical problem, the present utility model provides a modified asphalt quality detection device, which is applied to the detection of the quality of modified asphalt.

[0036] Specifically, please refer to Figures 1 - 5 , the modified asphalt quality detection device specifically includes:

[0037] A bearing box 1, a support mechanism 2 is arranged on the top of the bearing box 1. The support mechanism 2 is rotatably arranged, and the support mechanism 2 is connected with a first cylinder 3. The piston rod of the first cylinder 3 is connected with a connecting plate 301. The bottom of the connecting plate 301 is rotatably connected with a connecting box 305. A pressure sensor is installed in the connecting box 305. The pressure sensor is connected with a mounting plate 306, and a plurality of detection needles 309 are arranged at the bottom of the mounting plate 306. A support box 6 is arranged on the top of the bearing box 1 below the detection needles 309, and a friction block 7 is placed in the support box 6.

[0038] For the modified asphalt quality detection device provided by the present utility model, in this application, through the arranged support mechanism 2, the rotatable setting of the support mechanism 2 can switch the driving direction of the first cylinder 3, so that the detection needles 309 can be lifted or horizontally moved. When the detection needles 309 are lifted, they can penetrate into the asphalt to conduct a penetration test. When the detection needles 309 penetrate into the asphalt block and then move horizontally, they can drive the asphalt block to rub on the surface of the friction block 7 to conduct a wear resistance detection. Thus, the penetration and wear resistance can be detected by one device, and the operation is convenient and it is conducive to use.

[0039] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0041] It should be noted that like reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0042] Embodiment 1, please refer to Figures 1 - 5 , a modified asphalt quality detection device, including a bearing box 1. A support mechanism 2 is provided on the top of the bearing box 1. The support mechanism 2 is rotatably arranged, and the support mechanism 2 is connected to a first cylinder 3. The piston rod of the first cylinder 3 is connected to a connecting plate 301. The bottom of the connecting plate 301 is rotatably connected to a connecting box 305. A pressure sensor is installed in the connecting box 305. The pressure sensor is connected to a mounting plate 306, and a plurality of detection needles 309 are arranged at the bottom of the mounting plate 306. A support box 6 is provided on the top of the bearing box 1 below the detection needles 309. A friction block 7 is placed in the support box 6. By setting the support mechanism 2 in this application, the rotatable setting of the support mechanism 2 can switch the driving direction of the first cylinder 3, so that the detection needles 309 can be lifted or horizontally moved. When the detection needles 309 are lifted, they can penetrate into the asphalt to perform a penetration test. When the detection needles 309 penetrate into the asphalt block and then move horizontally, they can drive the asphalt block to rub on the surface of the friction block 7 to perform wear resistance detection. Thus, a device can be used to perform both penetration and wear resistance detection, and the operation is convenient and beneficial for use. The friction block 7 is placed in the support box 6, and friction blocks 7 with different materials and surface roughnesses can be replaced according to requirements.

[0043] Furthermore, as Figures 1 - 2 shown, the support mechanism 2 includes a support seat 201 installed on the top of the bearing box 1. Both sides of the top of the support seat 201 are fixedly connected with first connection seats 202. A first connection shaft 203 is fixedly connected between the two first connection seats 202. A second connection seat 204 is sleeved on the outer surface of the first connection shaft 203. The top end of the second connection seat 204 is fixedly connected with a support rod 205. The support rod 205 is fixedly connected to one side of the first cylinder 3. The first connection seat 202, the first connection shaft 203 and the second connection seat 204 can connect the support seat 201 and the support rod 205 together, and enable the support rod 205 to rotate relative to the support seat 201.

[0044] Furthermore, as Figure 2As shown in the figure, on one side of one of the first connection seats 202, a first hand-tightening bolt 207 is threadedly connected. On one side of the second connection seat 204 close to the first hand-tightening bolt 207, a number of first limiting holes 206 are provided. One end of the first hand-tightening bolt 207 is inserted into one of the first limiting holes 206. By inserting the first hand-tightening bolt 207 into the first limiting hole 206, the second connection seat 204 can be fixed, preventing the second connection seat 204 from rotating, and further preventing the support rod 205 from rotating.

[0045] Embodiment 2 further optimizes the modified asphalt quality detection device provided in Embodiment 1. Specifically, as Figure 1 and Figure 3 shown, two third connection seats 302 are fixedly installed at the bottom of the connecting plate 301. A second connecting shaft 303 is fixedly connected between the two third connection seats 302. A fourth connection seat 304 is sleeved on the outer surface of the second connecting shaft 303. The bottom of the fourth connection seat 304 is fixedly connected to the connection box 305. By the mutual cooperation of the third connection seat 302, the second connecting shaft 303 and the fourth connection seat 304, the connecting plate 301 and the screw hole 307 can be connected together, and the connecting plate 301 and the connection box 305 can rotate relative to each other.

[0046] Furthermore, as Figure 3 shown, a second hand-tightening bolt 311 is threadedly connected to one of the third connection seats 302. A number of second limiting holes 310 are provided on one side of the fourth connection seat 304 close to the second hand-tightening bolt 311. One end of the second hand-tightening bolt 311 is inserted into one of the second limiting holes 310. By inserting the second hand-tightening bolt 311 into the second limiting hole 310, the fourth connection seat 304 can be limited, preventing the fourth connection seat 304 from rotating, and further preventing the connection box 305 and the connecting plate 301 from rotating relative to each other.

[0047] Furthermore, as Figure 3 shown, a number of screw holes 307 are provided at the bottom of the mounting plate 306. The inner wall of the screw hole 307 is threadedly connected to a screw 308. The screw 308 is fixedly connected to the top end of the detection needle 309. This setting enables the detection needle 309 to be detached from the mounting plate 306, and thus different-sized detection needles 309 can be replaced.

[0048] Furthermore, a second cylinder is installed in the carrier box 1. The top end of the second cylinder passes through the carrier box 1 and is fixedly connected to the bottom of the support box 6. The second cylinder can drive the support box 6 to lift, thereby increasing the height of the support box 6.

[0049] Embodiment 3 further optimizes the modified asphalt quality detection device provided in Embodiment 1 or 2. Specifically, as Figure 1As shown in the figure, a slide rail 313 is fixedly installed on one side of the first cylinder 3. A slide seat is slidably connected to the outer surface of the slide rail 313. A limiting plate 312 is fixedly installed on one side of the slide seat. The bottom end of the limiting plate 312 is fixedly connected to the connecting plate 301. The cooperation of the slide rail 313, the slide seat and the limiting plate 312 can limit the connecting plate 301, making the movement of the connecting plate 301 more stable.

[0050] Further, as Figure 1 shown, a detection sensor 4 is embedded on one side of the slide rail 313. When the slide seat reaches the detection sensor 4, it can be detected by the detection sensor 4. Such a setting can confirm the number of reciprocations of the first cylinder 3 driving the asphalt block during the wear resistance test.

[0051] Further, as Figure 1 shown, a controller is arranged in the bearing box 1. The detection sensor 4, the first cylinder 3 and the pressure sensor are all connected to the controller. A touch screen 5 is fixedly installed on one side of the support seat 201, and the touch screen 5 is connected to the controller.

[0052] The use process of the modified asphalt quality detection device provided by the present utility model is as follows:

[0053] When performing the penetration test, refer to Figure 1 , place the asphalt block on the top of the friction block 7 and start the first cylinder 3. The first cylinder 3 pushes the connecting plate 301 to descend so that the detection needle 309 pierces into the asphalt block. During this process, the pressure sensor detects the piercing force, and after the detection is completed, observe the depth of penetration of the detection needle 309;

[0054] When performing the wear resistance test, refer to Figure 5 , insert the asphalt block and the detection needle 309 together. The second cylinder pushes the support box 6 to rise so that the friction block 7 contacts the bottom of the asphalt block. Then the first cylinder 3 pushes the connecting plate 301 to reciprocate, so that the asphalt block reciprocates on the surface of the friction block 7 for friction. During this process, the detection sensor 4 detects the number of times of the first cylinder 3 telescoping to confirm the number of frictions;

[0055] Figure 1 The operation of switching to the Figure 5 form is as follows: Rotate the first hand-tightening bolt 207 so that the first hand-tightening bolt 207 is separated from the first limiting hole 206. Rotate the second hand-tightening bolt 311 so that the second hand-tightening bolt 311 is separated from the second limiting hole 310. Rotate the support rod 205 to the horizontal, keep the detection needle 309 vertical, and then tighten the first hand-tightening bolt 207 and the second hand-tightening bolt 311; Figure 5 The operation of switching to the Figure 1The operation of the form is as follows: Rotate the first hand-tightening bolt 207 to separate the first hand-tightening bolt 207 from the first limiting hole 206, rotate the second hand-tightening bolt 311 to separate the second hand-tightening bolt 311 from the second limiting hole 310, rotate the support rod 205 to the erected state, keep the detection needle 309 vertical, and then tighten the first hand-tightening bolt 207 and the second hand-tightening bolt 311.
