Description

Technical Field

[0001] The present invention relates to the technical field of asphalt detection, and in particular to an emulsified asphalt bonding strength detection device. Background Art

[0002] Emulsified asphalt refers to asphalt that is used and processed in a way that is different from the traditional asphalt processing and use. Generally, asphalt is heated to above 150 degrees, becomes fluid, and then mixed with stone to be processed into road materials. The road is paved at high temperature and formed after cooling. Compared with ordinary modified asphalt, emulsified asphalt has the advantages of convenience and time saving in construction. The bonding strength of emulsified asphalt has a great impact on the service life of the road surface. In order to ensure the quality of the road, the bonding strength of emulsified asphalt needs to be tested before construction.

[0003] For example, the Chinese patent with patent number 201620221345.4 provides an emulsified asphalt bonding strength testing device. When in use, the connecting screws on both sides of the emulsified asphalt sample are respectively inserted into two sets of locking frames, and then the positions of the connecting screws are fixed by locking nuts. Finally, the tension device is controlled to pull one set of locking frames to move to pull the sample, and the bonding strength of the sample can be tested by the displacement sensor.

[0004] However, when current asphalt bonding strength testing devices are used, the test end of the testing device is mostly connected to a test steel plate bonded with an emulsified asphalt sample by bolts. The entire testing process requires cumbersome fixation of the test steel plate containing the asphalt. When the number of test samples is large, the traditional connection method will waste a lot of time, resulting in a decrease in the efficiency of the test. Summary of the invention

[0035] Compared with the prior art, the present invention has the following beneficial effects:

[0036] 1. When the device is in use, a test sample with test plates adhered on both sides is placed on the base, one group of test plates is in contact with the base, and then the driving mechanism is controlled to start and drive the lifting frame to descend. During the descent of the lifting frame, one group of connecting mechanisms is driven to descend until the lifting frame abuts against a group of test plates at the top, so that the two groups of connecting mechanisms are automatically fixedly connected with the two groups of test plates, and at the same time, the driving direction of the driving mechanism is changed to drive the lifting frame to rise. During the rising process of the lifting frame, one group of test plates is driven to rise through the connecting mechanism to pull the test sample.

[0037] 2. When the device is in use, the two sets of second bevel gears are driven to rotate synchronously by the power source. In the initial state, one set of the second bevel gear is meshed with the first bevel gear to drive the threaded sleeve to rotate, and then the threaded sleeve and one set of movable plates are driven to descend through the cooperation of the threaded sleeve and the screw rod, thereby controlling the lifting frame to descend. When the lifting frame descends to abut against the detection plate, the abutting column is pushed up and the wedge block is separated from the card frame, so that the movable plate can move under the reset ability of the elastic member, and the two sets of movable plates can move synchronously under the action of the connecting rod. During the movement, the movable rod controls the card frame to slide in the slide groove through the driving rod until it is connected with the card seat, thereby quickly completing the fixed connection with the detection plate, and the movable plate makes the two sets of second bevel gears slide at the same time during the movement to control the other set of second bevel gears to mesh with the first bevel gear, thereby changing the movement direction of the lifting frame to quickly perform the detection work.

[0038] 3. After the test is completed, the reset gear is driven to rotate by rotating the rocker. During the rotation of the reset gear, the connecting rod is driven to move horizontally, thereby driving the two sets of movable plates to reset so that the clamping frame is reset and separated from the clamping seat, which is convenient and quick to disassemble the test plate and the test sample after the test is completed. At the same time, the wedge block is clamped in the clamping frame again to reset the connection mechanism, and the two sets of second bevel gears are synchronized to slide again, switching the second bevel gear meshing with the first bevel gear for the next test. There is no need for cumbersome reset procedures and disassembly work, which further improves the work efficiency of asphalt testing. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0053] Example:

[0054] like Figure 1 , 2As shown in Figures 3 and 5, the present invention provides an emulsified asphalt bonding strength testing device, including a base 101, a lift frame 201 that can be raised or lowered is arranged on the base 101, test plates 106 are arranged on both sides of a test sample 108, a group of test plates 106 at the bottom is placed on the base 101, and connecting mechanisms are arranged in the base 101 and the lift frame 201, and the two groups of test plates 106 are automatically fixedly connected when the lift frame 201 contacts with a group of test plates 106 at the top through the connecting mechanism.

[0055] The connecting mechanism includes a movable plate 401. The movable plates 401 in the two groups of connecting mechanisms are respectively slidably set on the base 101 and the lifting frame 201. The two groups of movable plates 401 are connected by a linkage component to drive the two groups of movable plates 401 to slide synchronously. The linkage component includes a connecting rod 301. The connecting rod 301 can be laterally slidably set on the base 101. One group of movable plates 401 is fixedly connected to the connecting rod 301, and the other group of movable plates 401 is slidably sleeved on the connecting rod 301.

[0056] When in use, the two groups of test plates 106 are respectively bonded to the two sides of the test sample 108, and the test sample 108 is placed on the base 101, so that one group of test plates 106 is in contact with the base 101, and the lifting frame 201 is located directly above the other group of test plates 106. During the sliding process, one group of movable plates 401 can drive the connecting rod 301 to slide horizontally, thereby driving the other group of movable plates 401 to slide, and the movable plates 401 arranged on the lifting frame 201 can slide on the connecting rod 301 along its axis.

[0057] like Figure 3 , 4 As shown in Figure 5, in this embodiment, the connecting mechanism also includes a fixed seat 402, which is arranged at the end of the movable plate 401, and an abutment seat 205 is arranged in the base 101 and the lifting frame 201. An elastic member 407 is arranged between the fixed seat 402 and the abutment seat 205, and a fixing component is arranged on the fixed seat 402, through which the fixing component can be selectively fixed or released with the detection plate 106 during the sliding process of the movable plate 401. The fixing assembly includes two groups of relatively arranged clamping frames 405. The opposite surfaces of the base 101 and the lifting frame 201 are provided with sliding grooves 202. The clamping frames 405 are slidably clamped in the sliding grooves 202. A connecting column 406 is provided on the clamping frame 405. A driving rod 403 is provided on the connecting column 406. The driving rod 403 is hinged to the fixing seat 402. A clamping seat 107 is provided on the detection plate 106. The clamping frame 405 can be clamped in the clamping seat 107 during the sliding process.

[0058] The movable plate 401 drives the fixed seat 402 to slide during the sliding process, and then drives the two sets of clamping frames 405 to slide and open and close along the slide groove 202 through the setting of the two sets of driving rods 403. When the bottom set of detection plates 106 is placed on the base 101 or the lifting frame 201 is lowered to abut against the top set of detection plates 106, the clamping seats 107 on the detection plates 106 are located in the slide groove 202, and the clamping frames 405 can be clamped on the clamping seats 107 during the sliding process to complete the fixed connection between the detection end of the detection device and the detection plate 106.

[0059] like Figure 3 , 4 As shown, in this embodiment, the connection mechanism further includes a locking assembly, which is arranged on the lifting frame 201 and connected to one of the groups of movable plates 401 to fix the position of the movable plates 401 and release the fixation when the lifting frame 201 abuts against the detection plate 106. The locking assembly includes an abutment column 203, which is escalably arranged in the lifting frame 201 and extends outward, and a wedge block 204 is arranged on the abutment column 203, and a clamping frame 404 is arranged on one of the groups of movable plates 401, and the wedge block 204 is clamped in the clamping frame 404.

[0060] In the initial state, the wedge block 204 is stuck in the card frame 404, and the elastic member 407 is in a compressed state. When the lifting frame 201 descends to abut against the detection plate 106, the abutment column 203 is pushed to move so that the wedge block 204 is separated from the card frame 404 to release the position fixation of the card frame 404. The movable plate 401 can be controlled to slide under the reset ability of the elastic member 407, and then the card frame 405 slides until it is connected to the card seat 107. The entire connection process does not require the staff to perform tedious operations.

[0061] like Figures 1 to 3 As shown, in this embodiment, a driving mechanism connected to the lifting frame 201 is provided on the base 101, and the lifting frame 201 is driven to descend by the driving mechanism and to ascend when it contacts the detection plate 106. The driving mechanism includes a screw rod 102 fixedly provided on the base 101, a threaded sleeve 501 is screwed on the screw rod 102, and a limit groove 408 is provided on a group of movable plates 401 slidably sleeved on the connecting rod 301, and the threaded sleeve 501 is relatively slidably clamped in the limit groove 408.

[0062] The threaded sleeve 501 can be driven to rise and fall on the screw rod 102 by controlling the forward and reverse rotation of the threaded sleeve 501, and a group of movable plates 401 arranged on the connecting rod 301 of the movable sleeve can slide on the threaded sleeve 501, so that the lifting frame 201 can be driven to rise and fall by the lifting and falling of the threaded sleeve 501.

[0063] like Figures 1 to 3As shown, in this embodiment, the driving mechanism further includes a bidirectional driving component, which is arranged on the movable plate 401 and connected to the threaded sleeve 501, so as to drive the threaded sleeve 501 to rotate in opposite directions during the sliding process of the movable plate 401. The bidirectional driving component includes a first bevel gear 502 arranged on the threaded sleeve 501, two groups of second bevel gears 503 are rotatably arranged on the movable plate 401, and the two groups of second bevel gears 503 are arranged oppositely, wherein one group of second bevel gears 503 is meshed with the first bevel gear 502, and a power source connected to the two groups of second bevel gears 503 is arranged on the movable plate 401, and the two groups of second bevel gears 503 are driven to rotate synchronously by the power source. The power source includes two groups of first synchronous wheels 504, which are respectively arranged on two groups of second bevel gears 503. A driving motor 505 is arranged on the movable plate 401, and two groups of second synchronous wheels 506 are arranged on the output shaft of the driving motor 505. The two groups of second synchronous wheels 506 are respectively connected to the two groups of first synchronous wheels 504 through synchronous belts 507.

[0064] By controlling the driving motor 505 to start and drive the two sets of second synchronous wheels 506 to rotate, the two sets of second synchronous wheels 506 can drive the two sets of first synchronous wheels 504 to rotate in the same direction through the synchronous belt 507 during the rotation process, so as to drive the two sets of second bevel gears 503 to rotate in the same direction. In the initial state, the outer set of second bevel gears 503 are meshed with the first bevel gear 502, and the lifting frame 201 can be driven to rise and fall through the threaded sleeve 501 until the lifting frame 201 is lowered to contact the detection plate 106, and the movable plate 401 is controlled to slide under the action of the elastic member 407. During the sliding process, the movable plate 401 can drive the two sets of second bevel gears 503 to move at the same time, so that the other set of second bevel gears 503 is meshed with the first bevel gear 502, and the threaded sleeve 501 can be controlled to rotate in the opposite direction, thereby controlling the lifting frame 201 to rise. During the lifting frame 201 rises, the detection plate 106 can be driven to rise for detection work.

[0065] like Figure 2 , 3 As shown in Figures 5 and 6, in the present embodiment, a detection mechanism connected to one of the connection mechanisms is arranged in the base 101, the detection mechanism includes a tension sensor 103 fixedly arranged in the base 101, a display screen 105 electrically connected to the tension sensor 103 is arranged on the base 101, a slide frame 104 is arranged at the detection end of the tension sensor 103, two groups of connection columns 406 located in the base 101 are slidably penetrated on the driving rod 403, the ends of the connection columns 406 are slidably sleeved in the slide frame 104, the connection columns 406 slide in the slide frame 104 during the sliding opening and closing process of the clamping frame 405, and the connection columns 406 drive the slide frame 104 to rise and fall during the lifting and lowering process of the clamping frame 405 in the base 101.

[0066] During the rising process of the lifting frame 201, an upward pulling force is applied to one of the test plates 106, thereby pulling the test sample 108 and driving the lower test plate 106 to move upward slightly. During the movement of the lower test plate 106, the connecting column 406 can slide along its axis at the end of the driving rod 403 to adapt to the position offset of the lower test plate 106. The adhesion of the test sample 108 is tested by the tension sensor 103, and the data is displayed on the display screen 105. The greater the tension applied to the tension sensor 103 on the display screen 105, the stronger the adhesion strength of the test sample 108. The smaller the tension applied to the tension sensor 103 on the display screen 105, the weaker the adhesion strength of the test sample 108. In addition, in some preferred embodiments, a displacement sensor can be added between the two test plates 106 to measure the displacement between the two test plates 106, improve the data obtained by combining the tension sensor 103, and make the test result more accurate.

[0067] like Figure 1 , 3 As shown in FIG. 5 , in this embodiment, a rack 302 is provided on the connecting rod 301, and a reset gear 303 is rotatably provided on the base 101, the reset gear 303 is meshed with the rack 302, and a rocking wheel 304 is provided on the reset gear 303. After the detection is completed, the reset gear 303 can be driven to rotate by rotating the rocking wheel 304, and the reset gear 303 drives the connecting rod 301 to reset by meshing with the rack 302 during the rotation process, so as to control the two groups of movable plates 401 to reset, and then control the multiple groups of clamping frames 405 to reset, so as to quickly release the fixed connection between the two groups of detection plates 106, and at the same time, the two groups of second bevel gears 503 are reset, so that the driving mechanism can drive the lifting frame 201 to descend, so as to prepare for subsequent detection work.

[0068] Specific usage and beneficial effects of the present invention:

[0069] When the device is in use, a test sample 108 with test plates 106 adhered on both sides is placed on the base 101, one group of test plates 106 is in contact with the base 101, and then the driving mechanism is controlled to start and drive the lifting frame 201 to descend. During the descent of the lifting frame 201, one group of connecting mechanisms is driven to descend until the lifting frame 201 abuts against a group of test plates 106 at the top, so that the two groups of connecting mechanisms are automatically fixedly connected to the two groups of test plates 106, and at the same time, the driving direction of the driving mechanism is changed to drive the lifting frame 201 to rise. During the rising process, the lifting frame 201 drives one group of test plates 106 to rise through the connecting mechanism to pull the test sample 108. During the pulling process, the adhesion of the test sample 108 can be detected by the detection mechanism. The entire detection process does not require manual fixation of the position of the test plate 106, making it more efficient when testing multiple test samples 108.

[0070] When the device is in use, the two sets of second bevel gears 503 are driven to rotate synchronously by the power source. In the initial state, one set of second bevel gears 503 is meshed with the first bevel gear 502 to drive the threaded sleeve 501 to rotate, and then the threaded sleeve 501 and one set of movable plates 401 are driven to descend through the cooperation of the threaded sleeve 501 and the screw rod 102, thereby controlling the lifting frame 201 to descend. When the lifting frame 201 descends to abut against the detection plate 106, it pushes the abutment column 203 to move up and makes the wedge block 204 disengage from the card frame 404, and the resetting ability of the elastic member 407 can be used. The movable plate 401 is moved, and the two groups of movable plates 401 are moved synchronously under the action of the connecting rod 301. During the movement, the movable rod controls the clamping frame 405 to slide in the slide groove 202 through the driving rod 403 until it is connected with the clamping seat 107, thereby quickly completing the fixed connection with the detection plate 106. During the movement of the movable plate 401, the two groups of second bevel gears 503 slide at the same time to control the other group of second bevel gears 503 to mesh with the first bevel gear 502, thereby changing the movement direction of the lifting frame 201 to quickly perform the detection work.

[0071] After the test is completed, the reset gear 303 is driven to rotate by rotating the rocker 304. During the rotation of the reset gear 303, the connecting rod 301 is driven to move horizontally, thereby driving the two sets of movable plates 401 to reset so that the clamping frame 405 is reset and separated from the clamping seat 107, so as to facilitate and quickly disassemble the test plate 106 and the test sample 108 after the test is completed. At the same time, the wedge block 204 is clamped in the clamping frame 404 again to reset the connection mechanism, and at the same time, the two sets of second bevel gears 503 are synchronized to slide again, and the second bevel gear 503 meshing with the first bevel gear 502 is switched to prepare for the next test, without the need for cumbersome reset procedures and disassembly work, which further improves the work efficiency of asphalt testing.

It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments. On the basis of the present invention, some modifications or improvements can be made thereto, which is obvious to those skilled in the art.
