Description

Technical Field

[0001] This utility model relates to the field of asphalt concrete testing technology, specifically to a rutting resistance testing mechanism for asphalt concrete. Background Technology

[0002] Asphalt concrete, also known as asphalt concrete, is a mixture made by manually selecting mineral aggregates, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc. with a certain gradation and mixing them with a certain proportion of road asphalt materials under strict control conditions.

[0003] After asphalt concrete is laid, it needs to undergo rutting resistance testing to test its performance. The testing usually requires personnel to cut off a section of the paved road surface for testing, but cutting off the road surface can easily cause damage and cracks. Therefore, the testing process needs to be improved. Utility Model Content

[0004] The purpose of this invention is to provide a testing mechanism for the rutting resistance of asphalt concrete to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rutting resistance testing mechanism for asphalt concrete, comprising a mounting panel, a first fixing frame, a second fixing frame, a second guide frame, and the first guide frame.

[0006] A drive mechanism is mounted on the rear end face of the mounting panel, and a drive wheel is provided on the output shaft of the drive mechanism.

[0007] A detection box is placed on the drive wheel;

[0008] The fixed frame 2 is equipped with a drive mechanism 3, and a lead screw 2 is provided on the output shaft of the drive mechanism 3;

[0009] The fixed frame 1 is equipped with a drive mechanism 2, and a lead screw 1 is provided on the output shaft of the drive mechanism 2;

[0010] Hydraulic rod 2 is installed inside the guide frame 1, and a mounting bracket is provided on the output shaft of hydraulic rod 2;

[0011] The mounting bracket is fitted with a compression wheel;

[0012] The guide frame 2 is equipped with a hydraulic rod 1, and a frame is provided on the output shaft of the hydraulic rod 1;

[0013] The frame is fitted with a detection wheel.

[0014] Preferably, a driven wheel is fitted inside the mounting panel, and the driven wheel supports the testing box. By fitting the driven wheel inside the mounting panel, the testing box can be supported when placed inside the mounting panel.

[0015] Preferably, a support block is mounted on the bottom surface of the mounting panel, and a bearing base is welded to the bottom surface of the support block. The mounting panel can be installed and supported by the support block and the bearing base.

[0016] Preferably, the second fixing frame has a support frame one installed at both ends of its outer surface, and the bottom end of the support frame one is welded to the mounting panel. The second fixing frame can be fixed to the mounting panel by means of the support frame one.

[0017] Preferably, support frames 2 are welded to both ends of the outer surface of the fixing frame 1, and the bottom end of the support frame 2 is welded to the mounting panel. The fixing frame 1 can be installed and fixed on the mounting panel by means of the support frame 2.

[0018] Preferably, a limiting rod 1 is welded inside the guide frame 1, and a limiting rod 2 is sleeved on the bottom end face of the limiting rod 1, with the bottom end face of the limiting rod 2 welded to the mounting frame. By sleeved on the bottom end face of the limiting rod 1 and the limiting rod 2, when the mounting frame moves up and down under the push of the hydraulic rod 2, the middle position of the mounting frame is limited and guided by the limiting rod 2 sleeved within the limiting rod 1.

[0019] Preferably, the guide frame is sleeved inside the fixed frame one, and the guide frame one is threaded onto the lead screw one. The guide frame is sleeved inside the fixed frame one for limiting the movement. When the guide frame one is threaded onto the lead screw one, the personnel can open the drive mechanism two to drive the lead screw one to rotate, and the guide frame one can move left and right according to the rotation direction of the lead screw one.

[0020] Preferably, the guide frame two is sleeved inside the fixed frame two, and the guide frame two is threaded onto the lead screw two. The guide frame two is sleeved inside the fixed frame two for limiting its position. When limited, the guide frame two is threaded onto the lead screw two, allowing personnel to open the drive mechanism three to rotate the lead screw two. The guide frame two can then move left or right according to the rotation direction of the drive mechanism three.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] 1. This utility model, by setting up a testing box, allows personnel to directly receive the asphalt concrete to be tested when it is necessary to test its rutting resistance. This allows the asphalt concrete to be discharged into the testing box during the laying of the roadbed. After discharge, the testing box can be securely placed on the drive wheel and driven wheel, achieving proper positioning. Next, the personnel can activate drive mechanism one to drive the drive wheel to rotate. During the rotation of the drive wheel, the testing box will move left and right, thereby adjusting its position. After adjustment, it can be limited by a guide frame connected to the fixed frame one. It is worth noting that guide frame one is threaded onto lead screw one. Therefore, when the personnel activate drive mechanism two to rotate lead screw one, guide frame one can move left and right according to the rotation direction of lead screw one. During the movement of guide frame one, the personnel can also activate hydraulic rod two to push the mounting frame and move the extrusion wheel downwards. When the extrusion roller moves down and contacts the asphalt concrete inside the testing chamber, it moves along with the guide frame, thus laying and leveling the asphalt concrete inside the testing chamber. This satisfies the requirements for receiving and laying asphalt concrete, avoiding the adverse effects on subsequent testing results caused by directly cutting into the road surface.

[0023] 2. This utility model, by setting up a testing wheel, allows for the limiting of asphalt concrete placement within the testing box after personnel have laid and smoothed it. The guide frame, second in connection with the fixed frame, provides positioning. During this process, the guide frame is threaded onto a lead screw, allowing personnel to activate the drive mechanism, causing the lead screw to rotate. The guide frame moves left or right according to the rotation direction of the drive mechanism. As the guide frame moves, personnel activate the hydraulic rod, using the frame to move the testing wheel downwards. Once the testing wheel reaches the asphalt concrete, it repeatedly rolls over it as the guide frame moves. Personnel can then observe the rolling marks to test the rutting resistance, thus successfully completing the testing operation. Furthermore, after testing, the testing box can be removed, the asphalt concrete emptied, and refilled for the next test. Attached Figure Description

[0032] 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.

[0033] Example 1

[0034] like Figures 1-7 As shown, the present invention proposes a testing mechanism for the rutting resistance of asphalt concrete, comprising a mounting panel 2, a fixing frame 4, a fixing frame 7, a guide frame 9, and a guide frame 12.

[0035] A drive mechanism 21 is mounted on the rear end face of the mounting panel 2, and a drive wheel 20 is provided on the output shaft of the drive mechanism 21.

[0036] A detection box 5 is placed on the drive wheel 20;

[0037] The fixed frame 27 is equipped with a drive mechanism 3 23, and the output shaft of the drive mechanism 3 23 is provided with a lead screw 24;

[0038] A drive mechanism 25 is installed inside the fixed frame 4, and a lead screw 15 is provided on the output shaft of the drive mechanism 25. As is well known to those skilled in the art, the provision of drive mechanisms 21, 25, and 23 is commonplace, belonging to conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can arbitrarily select and equip them according to their needs or convenience. Drive mechanisms 21, 25, and 23 respectively drive the drive wheel 20, lead screw 15, and lead screw 24 to rotate.

[0039] A hydraulic rod 16 is installed inside the guide frame 12, and a mounting bracket 14 is provided on the output shaft of the hydraulic rod 16;

[0040] The mounting bracket 14 is fitted with a compression roller 19;

[0041] A hydraulic rod 8 is installed inside the guide frame 2 9, and a frame 10 is provided on the output shaft of the hydraulic rod 8;

[0042] The frame 10 is fitted with a detection wheel 11.

[0043] A driven wheel 22 is fitted inside the mounting panel 2, and the driven wheel 22 supports the detection box 5.

[0044] The outer surfaces of the fixed frame 4 are welded with support frames 2 13 at both ends, and the bottom surface of the support frames 2 13 is welded to the mounting panel 2. The fixed frame 4 can be installed and fixed on the mounting panel 2 through the support frames 2 13.

[0045] A limiting rod 17 is welded inside the guide frame 12. The bottom end of the limiting rod 17 is sleeved with a limiting rod 18, and the bottom end of the limiting rod 18 is welded to the mounting frame 14. When the mounting frame 14 is pushed up and down by the hydraulic rod 16, the middle position of the mounting frame 14 is limited and guided by the limiting rod 17 through the limiting rod 18.

[0046] Guide frame 12 is sleeved inside fixed frame 4, and guide frame 12 is threaded onto lead screw 15. Guide frame 12 is sleeved inside fixed frame 4 for limiting. When the guide frame 12 is threaded onto lead screw 15, the personnel can open drive mechanism 25 to drive lead screw 15 to rotate. According to the rotation direction of lead screw 15, guide frame 12 can be moved left and right.

[0047] Based on Example 1: When personnel test the rutting resistance of asphalt concrete, they can directly collect the asphalt concrete to be tested using the testing box 5. The asphalt concrete is discharged into the testing box 5 when laid on the roadbed. After discharge, the personnel can place the testing box 5 on the driving wheel 20 and driven wheel 22. After placement, the personnel can open the drive mechanism 21 to rotate the driving wheel 20, which moves the testing box 5 left and right, thus adjusting its position. After adjustment, the guide frame 12 is fitted into the fixed frame 4 for limiting the position. During limiting, the guide frame 12... The screw is threaded onto the lead screw 15, allowing personnel to open the drive mechanism 25 to rotate the lead screw 15. The rotation direction of the lead screw 15 then moves the guide frame 12 left and right. While the guide frame 12 is moving, personnel can open the hydraulic rod 2 16 to push the mounting frame 14, causing the extrusion wheel 19 to move downwards. After the extrusion wheel 19 moves downwards, it contacts the asphalt concrete inside the testing box 5. As the guide frame 12 moves, it moves the extrusion wheel 19, allowing it to lay and smooth the asphalt concrete inside the testing box 5. This satisfies the requirements for asphalt concrete receiving and laying, avoiding the direct cutting of the road surface which would affect subsequent testing.

[0048] Example 2

[0049] like Figures 1-7 As shown, the present invention proposes a testing mechanism for the rutting resistance of asphalt concrete. Compared with Embodiment 1, this embodiment further includes: a mounting panel 2, a fixing frame 4, a fixing frame 7, a guide frame 9, and a guide frame 12.

[0050] A drive mechanism 21 is mounted on the rear end face of the mounting panel 2, and a drive wheel 20 is provided on the output shaft of the drive mechanism 21.

[0051] A detection box 5 is placed on the drive wheel 20;

[0052] The fixed frame 27 is equipped with a drive mechanism 3 23, and the output shaft of the drive mechanism 3 23 is provided with a lead screw 24;

[0053] A drive mechanism 25 is installed inside the fixed frame 4, and a lead screw 15 is provided on the output shaft of the drive mechanism 25;

[0054] A hydraulic rod 16 is installed inside the guide frame 12, and a mounting bracket 14 is provided on the output shaft of the hydraulic rod 16;

[0055] The mounting bracket 14 is fitted with a compression roller 19;

[0056] A hydraulic rod 8 is installed inside the guide frame 2 9, and a frame 10 is provided on the output shaft of the hydraulic rod 8;

[0057] The frame 10 is fitted with a detection wheel 11.

[0058] The bottom surface of the mounting panel 2 is equipped with a support block 1, and the bottom surface of the support block 1 is welded with a bearing base 3. The mounting panel 2 can be installed and supported by the support block 1 and the bearing base 3.

[0059] The outer surfaces of the second fixing bracket 7 are each equipped with a first support bracket 6, and the bottom end of the first support bracket 6 is welded to the mounting panel 2. The second fixing bracket 7 can be fixed to the mounting panel 2 by means of the first support bracket 6.

[0060] Guide frame 29 is sleeved inside fixed frame 27, and guide frame 29 is threaded onto lead screw 24. Guide frame 29 is sleeved inside fixed frame 27 for limiting. When the guide frame 29 is limited, it is threaded onto lead screw 24, so that when the personnel open drive mechanism 3 23 to drive lead screw 24 to rotate, guide frame 29 can move left and right according to the rotation direction of drive mechanism 3 23.

[0061] Based on Example 2: After the asphalt concrete is laid and smoothed inside the testing box 5, the personnel limit its position by connecting the guide frame 29 to the fixed frame 27. When the guide frame 29 is limited, it is threaded onto the lead screw 24. When the personnel open the drive mechanism 3 23 to rotate the lead screw 24, the guide frame 29 can move left and right according to the rotation direction of the drive mechanism 3 23. When the guide frame 29 moves, the personnel can open the hydraulic rod 1 8 to drive the testing wheel 11 to move down through the frame 10. After the testing wheel 11 moves down, it contacts the asphalt concrete. When the guide frame 29 moves, it drives the testing wheel 11 to roll back and forth on the asphalt concrete and observe the rolling marks to test the rutting resistance performance, thus meeting the testing requirements. After the test, the personnel can remove the testing box 5, pour out the asphalt concrete inside, and refill it for testing again.

[0062] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
