Description

Technical Field

[0001] This invention relates to the field of asphalt performance testing technology, and in particular to an asphalt performance testing device. Background Technology

[0002] As an innovative material, new asphalt is meticulously crafted into a high-performance composite material by incorporating advanced modifiers such as rubber, resin, and high-molecular polymers, or through refined oxidation processing techniques. However, before the new asphalt is officially applied to road paving, its various properties must undergo comprehensive and rigorous testing and evaluation.

[0003] Currently, the performance testing of new asphalt typically only involves compaction testing, making it impossible to conduct rolling tests under different stable pressure conditions. Furthermore, it is impossible to adjust the thickness of the compacted asphalt as needed, thus failing to better simulate the usage state of asphalt after paving. Summary of the Invention

[0004] To address the problems in the background art, the present invention provides an asphalt performance testing device that can precisely adjust the compaction thickness of the asphalt to be tested in the asphalt addition hole as needed, and can also adjust the downward pressure on both sides of the tracked testing wheel, thereby achieving compaction testing by applying stable pressure to the asphalt to be tested.

[0005] The present invention provides an asphalt performance testing device, which specifically includes: a main body of the device, a bottom support frame, an adjustment plate, and performance testing components; The bottom support frame is connected to the bottom side of the main body of the equipment. An asphalt addition hole is provided in the middle of the inner bottom of the main body of the equipment. A set of limiting baffles is provided at the bottom front outer end of the asphalt addition hole. The length of the limiting baffles is greater than the length of the asphalt addition hole. A hydraulic cylinder is also installed on the top of the main body of the equipment. The bottom of the telescopic end of the hydraulic cylinder is connected to a pressure plate by bolts. The left and right ends of the pressure plate are respectively connected to guide frames with inverted U-shaped structures by bolts. The adjusting plate is slidably installed inside the base support frame via locking slots at both ends and locking posts on the inner side walls of the base support frame. The telescopic end of the hydraulic adjusting cylinder installed in the middle of the bottom of the base support frame is connected to the bottom of the adjusting plate by bolts. An asphalt locking frame also slides on the adjusting plate, and side scrapers are provided on both sides of the asphalt locking frame. The performance testing component includes tracked testing wheels, an inverted U-shaped support frame, a sliding frame, a moving plate, and an adjusting insert shaft; The inverted U-shaped support frame is fitted onto both ends of the drive wheel shaft on the tracked detection wheel, and a sliding frame is rotatably connected to the top of the inverted U-shaped support frame. The sliding frame slides through the moving plate, and the two ends of the moving plate are respectively side U-shaped structures, which are respectively clamped onto the crossbeams at the front and rear ends of the inner side of the equipment body. Two sets of adjusting shafts are respectively slidably inserted into both ends of the drive wheel shaft on the tracked detection wheel through keyways.

[0006] Furthermore, the pressure plate and the upper end of the asphalt adding hole are the same size and are opposite each other. The lower end of the asphalt positioning frame is attached to the adjustment plate, and the upper end engages with the stepped structure at the lower end of the asphalt adding hole.

[0007] Furthermore, a scale plate is fixed to the lower end of the main body of the equipment and the front end face of the bottom support frame, and the initial scale line on the scale plate is flush with the inner bottom of the main body of the equipment.

[0008] Furthermore, the front and rear ends of the adjusting plate are respectively connected to two sets of vertical plates, and a pusher shaft is installed between the front and rear vertical plates. The middle of the adjusting shaft has a threaded structure and is threadedly connected to the threaded cylinder fixed on the side scraper. The front end of the adjusting shaft is also connected to an operating handwheel.

[0009] Furthermore, the rear end of the adjustment plate is provided with two sets of square drainage holes, and the square drainage holes are located at the front end of the two sets of rear upright plates, with a length greater than that of the side scraper.

[0010] Furthermore, a drive shaft is inserted at the front end of the movable plate and a guide shaft is inserted at the rear end. A reciprocating lead screw is provided in the middle of the drive shaft and meshes with the front end of the movable plate. Both ends of the drive shaft are optical shaft structures and are rotatably inserted into the insert. One end is also connected to the drive motor installed on the top of the equipment body through chain transmission. The insert and the guide shaft are both connected to the inner wall of the equipment body by bolts.

[0011] Furthermore, the performance testing component also includes an external connecting shaft, gears, a rotating sleeve, a pressure adjusting rod, and an I-shaped slider; The outer ends of the two sets of adjusting shafts are respectively connected to the external connecting shaft via universal joints, and the outer ends of the external connecting shafts are respectively fitted with rotating sleeves. The pressure adjusting rod is a threaded rod that passes through the threaded hole on the I-shaped slider through the thread. The bottom end is a smooth shaft structure and is rotatably clamped to the top of the rotating sleeve. The I-shaped slider is slidably installed in the groove of the crossbeam.

[0012] Furthermore, the inner rear end of the main body of the equipment is provided with a square frame, with vertical guide rods inserted at both ends of the frame. A top spring is fitted at the bottom of the vertical guide rod, and the top of the guide rod is connected to the bottom of the crossbeam of the rear assembly. The outer connecting shaft of the rear assembly passes through the frame and is equipped with a gear, which meshes with the retaining teeth at the bottom of the inner side of the frame.

[0013] Furthermore, ball bearings are embedded in the engagement surfaces of the movable plate and the I-shaped slider that engage with the crossbeam.

[0014] The asphalt performance testing device provided by this invention has the following beneficial effects: This invention can precisely adjust the compaction thickness of the asphalt to be tested in the asphalt addition hole as needed, and can also adjust the downward pressure on both sides of the tracked testing wheel, thereby achieving compaction testing by applying stable pressure to the asphalt to be tested.

[0015] Furthermore, by setting up a hydraulic adjusting cylinder and an adjusting plate, the height of the adjusting plate can be adjusted by the hydraulic adjusting cylinder to adjust the depth of the asphalt positioning frame inserted into the bottom of the asphalt adding hole, thereby changing the thickness of the asphalt in the asphalt adding hole and the asphalt positioning frame. After the test is completed, the adjusting plate is moved downward by the hydraulic adjusting cylinder, and the asphalt positioning frame is dislodged from the bottom of the asphalt adding hole. Under the action of the limiting baffle at the front end of the bottom side of the asphalt adding hole, the asphalt inside the asphalt adding hole can leak to the sides or front of the asphalt positioning frame, but will not leak to the front end. By rotating the pusher shaft, the asphalt positioning frame is moved to the rear, thereby pushing the asphalt out of the adjusting plate for subsequent testing.

[0016] In addition, by setting up a hydraulic cylinder and a pressure plate, the pressure plate can compact and flatten the asphalt in the asphalt addition hole and the asphalt positioning frame, and the hydraulic adjustment cylinder can adjust the height of the adjustment plate so that the top of the flattened asphalt is level with the top surface of the asphalt addition hole. Then, the thickness value of the asphalt in the asphalt addition hole and the asphalt positioning frame can be read by the scale on the scale plate so that the thickness of the compacted and flattened asphalt reaches the required level.

[0017] In addition, by setting up a performance testing component, the two sets of pressure adjusting rods can be rotated to drive the rotating sleeves on both sides to move downwards, thereby adjusting the downward pressure of the tracked testing wheel. Since the outer connecting shaft and the adjusting insert shaft are connected by a universal joint, the pressure on both sides of the tracked testing wheel can be adjusted to the same pressure or different pressures, so as to achieve compaction testing by applying stable pressure to the asphalt to be tested during the process of driving the tracked testing wheel to move left and right.

Detailed Implementation

[0022] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.

[0023] Example 1: Please refer to Figures 1 to 11 : This invention proposes an asphalt performance testing device, comprising: a main body 1, a bottom support frame 2, an adjustment plate 3, and a performance testing component 4; The bottom support frame 2 is connected to the bottom side of the equipment body 1. The bottom of the inner side of the equipment body 1 is provided with an asphalt adding hole 101. The bottom front outer end of the asphalt adding hole 101 is provided with a set of limiting baffles 102. The length of the limiting baffles 102 is greater than the length of the asphalt adding hole 101. When the asphalt positioning frame 304 is dislodged from the bottom of the asphalt adding hole 101, and under the action of the limiting baffles 102 at the bottom front of the asphalt adding hole 101, the asphalt inside the asphalt adding hole 101 can leak to the sides or front of the asphalt positioning frame 304, but will not leak to the front end. At the same time, it can also limit the forward movement of the asphalt positioning frame 304 so that the asphalt positioning frame 304 can be inserted upward into the bottom of the asphalt adding hole 101. A hydraulic cylinder 103 is also installed on the top of the main body 1 of the equipment. The bottom of the telescopic end of the hydraulic cylinder 103 is connected to a pressure plate 104 by bolts. The left and right ends of the pressure plate 104 are respectively connected to a guide frame 1041 with an inverted U-shaped structure by bolts. The adjusting plate 3 is slidably installed inside the base support frame 2 via the locking slots 301 at both ends and the locking posts 201 on the inner side walls of the base support frame 2. The telescopic end of the hydraulic adjusting cylinder 202 installed in the middle of the bottom of the base support frame 2 is connected to the bottom of the adjusting plate 3 by bolts. An asphalt locking frame 304 also slides on the adjusting plate 3, and side scrapers 3041 are respectively provided on both sides of the asphalt locking frame 304. Performance testing component 4 includes tracked testing wheel 401, inverted U-shaped support frame 402, sliding frame 403, moving plate 404, and adjusting shaft 405; An inverted U-shaped support frame 402 is fitted onto both ends of the drive wheel shaft on the tracked detection wheel 401, and a sliding frame 403 is rotatably connected to the top of the inverted U-shaped support frame 402. The sliding frame 403 slides through the moving plate 404, and the two ends of the moving plate 404 are respectively side U-shaped structures, which are respectively clamped on the crossbeams 105 at the front and rear ends of the inner side of the main body 1. Two sets of adjusting shafts 405 are respectively slidably inserted into both ends of the drive wheel shaft on the tracked detection wheel 401 through keyways. The performance testing component 4 also includes an external shaft 406, a gear 4061, a rotating sleeve 407, a pressure adjusting rod 408, and an I-shaped slider 409. The outer ends of the two sets of adjusting shafts 405 are respectively connected to the external shaft 406 via universal joints, and the outer ends of the external shafts 406 are respectively fitted with rotating sleeves 407. The pressure adjusting rod 408 is a threaded rod that passes through the threaded hole on the I-shaped slider 409 through the thread. The bottom end is a smooth shaft structure and is rotatably clamped to the top of the rotating sleeve 407. The I-shaped slider 409 is slidably installed in the slide groove 1051 of the crossbeam 105.

[0024] In embodiments of the present invention, such as Figure 4 and Figure 5 As shown, the upper ends of the pressing plate 104 and the asphalt adding hole 101 are the same size and are opposite each other. The drive shaft 1061 and the guide shaft 107 are located on both sides of the pressing plate 104. The lower end of the asphalt positioning frame 304 is attached to the adjusting plate 3, and the upper end is engaged with the stepped structure at the lower end of the asphalt adding hole 101. After the new asphalt to be tested is added into the asphalt adding hole 101 and the asphalt positioning frame 304, the pressing plate 104 can be driven by the hydraulic cylinder 103 to compact and flatten the asphalt in the asphalt adding hole 101 and the asphalt positioning frame 304.

[0025] In embodiments of the present invention, such as Figure 4 and Figure 6 As shown, a scale plate 5 is fixed to the lower end of the main body 1 and the front end face of the bottom support frame 2. The initial scale line on the scale plate 5 is flush with the inner bottom of the main body 1. After the flattened top of the asphalt is flush with the top surface of the asphalt adding hole 101, the thickness value of the asphalt in the asphalt adding hole 101 and the asphalt positioning frame 304 can be read by the scale on the scale plate 5.

[0026] In embodiments of the present invention, such as Figure 6 As shown, the front and rear ends of the adjusting plate 3 are respectively connected to two sets of vertical plates 302, and a pusher shaft 303 is installed between the front and rear vertical plates 302. The middle of the adjusting shaft 203 has a threaded structure and is threadedly connected to the threaded cylinder fixed on the side scraper 3041. The front end of the adjusting shaft 203 is also connected to an operating handwheel. One set of pusher shafts 303 can be rotated by operating the handwheel, and the other set of pusher shafts 303 can be driven to rotate synchronously through the chain. By utilizing the threaded structure in the middle of the pusher shaft 303 and the threaded connection between the threaded structure and the threaded cylinder fixed on the side scraper 3041, the asphalt positioning frame 304 can be moved to the rear.

[0027] In embodiments of the present invention, such as Figure 10As shown, the rear end of the adjusting plate 3 is also provided with two sets of square holes 305, and the square holes 305 are located at the front end of the two sets of rear upright plates 302 respectively. The length is greater than the length of the side scraper 3041. When the asphalt positioning frame 304 moves backward to push out the asphalt, the asphalt at the rear end of the side scraper 3041 can be pushed into the square holes 305 and fall down.

[0028] In embodiments of the present invention, such as Figure 1 and Figure 9 As shown, a drive shaft 1061 is inserted through the front end of the movable plate 404, and a guide shaft 107 is inserted through the rear end. A reciprocating screw is provided in the middle of the drive shaft 1061, which meshes with the front end of the movable plate 404. Both ends of the drive shaft 1061 are optical shaft structures and are respectively rotatably inserted into the insert 1062. One end is also connected to the drive motor 106 installed on the top of the equipment body 1 through chain transmission. The insert 1062 and the guide shaft 107 are both connected to the inner wall of the equipment body 1 by bolts. The drive shaft 1061 can be rotated by the drive motor 106, and then the reciprocating screw in the middle of the drive shaft 1061 meshes with the front end of the movable plate 404, thereby moving the movable plate 404.

[0029] In embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the inner rear end of the main body 1 of the equipment is also provided with a square frame 108. Vertical guide rods 109 are inserted at both ends of the frame 108. A top spring 1091 is fitted at the bottom end of the vertical guide rod 109, and the top end is connected to the bottom of the crossbeam 105 of the rear assembly. The outer connecting shaft 406 of the rear assembly passes through the frame 108 and is equipped with a gear 4061. The gear 4061 meshes with the retaining teeth 1081 at the bottom inner end of the frame 108, so that the frame 108 can be adjusted up and down with the outer connecting shaft 406 on one side of the gear 1061, and the retaining teeth at the bottom inner end of the frame 108 are always meshed with the gear 4061 on the outer connecting shaft 406.

[0030] Example 2, based on Example 1, such as Figure 11 As shown, ball bearings are embedded in the engagement surfaces of the movable plate 404 and the I-shaped slider 409 with the crossbeam 105. When the tracked detection wheel 401 is driven to move left and right by the drive motor 106, the movable plate 404 and the I-shaped slider 409 can slide more smoothly on the crossbeam 105.

[0031] The specific usage and function of this embodiment are as follows: In this invention, the height of the adjusting plate 3 is adjusted by the hydraulic adjusting cylinder 202, and the depth of the asphalt positioning frame 304 inserted into the bottom end of the asphalt adding hole 101 is adjusted. New asphalt to be tested is added into the asphalt adding hole 101 and the asphalt positioning frame 304. The hydraulic cylinder 103 drives the pressing plate 104 to compact and flatten the asphalt in the asphalt adding hole 101 and the asphalt positioning frame 304. Then, the height of the adjusting plate 3 is adjusted upwards by the hydraulic adjusting cylinder 202 so that the top of the flattened asphalt is level with the top surface of the asphalt adding hole 101. The asphalt is then measured using a scale line. The scale on plate 5 reads the thickness value of the asphalt in the asphalt adding hole 101 and the asphalt positioning frame 304. When the value is less than the required thickness, the height of the adjusting plate 3 is adjusted downward by the hydraulic adjusting cylinder 202 to continue adding asphalt, and then the plate 104 is used to compact and flatten it again. Then the height of the adjusting plate 3 is adjusted upward so that the top of the flattened asphalt is level with the top surface of the asphalt adding hole 101. The thickness of the asphalt is read again. This process is repeated several times until the thickness of the asphalt in the asphalt adding hole 101 and the asphalt positioning frame 304 after compaction and flattening reaches the required thickness. The drive motor 106 drives the drive shaft 1061 to rotate, which in turn drives the reciprocating screw in the middle of the drive shaft 1061 to mesh with the front of the moving plate 404, thus moving the moving plate 404. This movement is achieved through the sliding frame 403 and the inverted U-shaped support 402, which in turn moves the drive wheel shaft on the tracked detection wheel 401, as well as the adjusting shaft 405 and the outer connecting shaft 406. Since the gear 4061 on the outer connecting shaft 406 meshes with the retaining teeth at the bottom inner side of the frame 108, the outer connecting shaft 406 can rotate during movement. This rotation, via the adjusting shaft 405, drives the drive wheel on the tracked detection wheel 401 to rotate, pushing the tracked detection wheel 401 onto the asphalt to be tested. Rotating the two sets of pressure adjusting rods 408 moves the rotating sleeves 407 on both sides downwards, adjusting the downward pressure of the tracked detection wheel 401. Because the outer connecting shaft 406 and the adjusting shaft 405... The shafts 405 are connected by a universal joint. The inner end of the adjusting insert shaft 405 is slidably inserted into both ends of the drive wheel shaft on the tracked detection wheel 401. The sliding frame 403 is slidably installed on the moving plate 404. The bottom end of the sliding frame 403 is rotatably connected to the top end of the inverted U-shaped support 402, which can adjust the pressure on both sides of the tracked detection wheel 401 to the same pressure or different pressure. At the same time, since the two ends of the strip frame 108 are slidably installed on the vertical guide rod 109, and under the action of the top spring 1091, the strip frame 108 can follow the external connecting shaft 406 on one side of the gear 1061 to adjust up and down. The retaining teeth at the bottom inner end of the strip frame 108 are always engaged with the gear 4061 on the external connecting shaft 406. During the process of driving the tracked detection wheel 401 to move left and right by the drive motor 106, the compaction test of applying stable pressure to the asphalt to be tested is realized. After the test is completed, the hydraulic adjusting cylinder 202 drives the adjusting plate 3 to move downward, and the asphalt positioning frame 304 disengages from the bottom end of the asphalt adding hole 101. Under the action of the limiting baffle 102 at the front end of the bottom side of the asphalt adding hole 101, the asphalt inside the asphalt adding hole 101 can leak to the sides or front of the asphalt positioning frame 304, but will not leak to the front end. By rotating a set of pusher shafts 303, and driving another set of pusher shafts 303 to rotate synchronously through the chain, the asphalt positioning frame 304 moves backward by utilizing the threaded connection between the middle thread structure of the pusher shaft 303 and the threaded cylinder fixed on the side scraper 3041, thereby pushing the asphalt out of the adjusting plate 3 for subsequent testing.

[0032] The following points should be noted in this article: 1. The accompanying drawings of the embodiments of the present invention only involve the structures involved in the embodiments of the present invention; other structures can refer to general designs.

[0033] 2. Where there is no conflict, the embodiments of the present invention and the features thereof can be combined with each other to obtain new embodiments.

[0034] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
