Description
Technical Field
[0001] This application relates to the field of performance testing of asphalt mixtures, and particularly to an apparatus for testing the performance of asphalt mixtures. Background Art
[0002] Asphalt is a dark brown complex mixture composed of hydrocarbon compounds with different molecular weights and their non-metallic derivatives. It is a kind of highly viscous organic liquid and an organic cementitious material for waterproofing, moisture-proofing and anti-corrosion. It mostly exists in the form of asphalt or tar, with a black surface, and is often mixed with other aggregates to form asphalt mixtures for use, commonly used in paving roads.
[0003] When using asphalt mixtures to pave roads, it is necessary to detect the ratio of the mixed asphalt and aggregates to improve the strength of the paved road surface. When testing asphalt mixtures, generally, cylindrical asphalt mixture blocks are formed from asphalt and aggregates in a mold, and then the asphalt mixture blocks are placed between two clamping blocks. Then, the two clamping blocks are used to squeeze the asphalt mixture blocks, and calculations are made by referring to the displacement data of the two clamping blocks and the applied force to complete the test.
[0004] During the test, generally, the testing personnel directly place the formed asphalt mixture block between the two clamping blocks, and then visually observe whether the asphalt mixture block is located in the middle position between the clamping blocks, and then directly adjust it by hand to reduce the influence of the offset placement of the asphalt mixture block on the test data. However, when the testing personnel directly observe the placement position of the asphalt mixture block with their eyes and then adjust it by hand, there may be errors, resulting in relatively large errors in the test of the asphalt mixture block. Summary of the Utility Model
[0005] The purpose of this application is to solve the problem that when the testing personnel directly observe the placement position of the asphalt mixture block with their eyes and then adjust it by hand, there may be errors, resulting in relatively large errors in the test of the asphalt mixture block as mentioned in the above background art. This application provides an apparatus for testing the performance of asphalt mixtures.
[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:
[0007] An asphalt mixture performance detection device includes a detection table, on which a hydraulic telescopic rod is fixed. The telescopic end of the hydraulic telescopic rod is fixed with a first clamping block, and a second clamping block is arranged on the first clamping block. Both the first clamping block and the second clamping block are arc-shaped. Two symmetric sliding rods are fixed on the first clamping block. The sliding rods penetrate through the second clamping block and are slidably connected to the second clamping block. A ranging sensor is fixed on the second clamping block, and the telescopic end of the ranging sensor abuts against the first clamping block. A support frame is fixed on the detection table, and a resisting rod is fixed on the support frame. A control computer is fixed on one side of the detection table. An alignment mechanism is arranged on one side of the support frame, and a locking mechanism is arranged on the support frame.
[0008] By adopting the above technical solution, move the alignment mechanism to both ends of the asphalt mixture block clamped by the first clamping block and the second clamping block, and then the alignment mechanism moves closer to both ends of the asphalt mixture block at the same time, so that the alignment mechanism pushes both ends of the asphalt mixture block, making the asphalt mixture block located at the middle position clamped by the first clamping block and the second clamping block. Thus, it can make the asphalt mixture block more accurately located at the middle position between the first clamping block and the second clamping block, reducing the possibility of uneven force when squeezing the asphalt mixture block and affecting the detection value.
[0009] Further, the alignment mechanism includes two symmetrically fixed first support plates on the support frame. Second support plates are fixed on both of the two first support plates. Two symmetric alignment push plates are arranged between the two second support plates. A synchronous movement component is arranged between the two alignment push plates and the two second support plates.
[0010] By adopting the above technical solution, the synchronous movement component drives the two alignment push plates to move simultaneously, so that the two alignment push plates push the asphalt mixture block, making the asphalt mixture block located between the first clamping block and the second clamping block. Thus, it can make the asphalt mixture block located at the middle position between the first clamping block and the second clamping block, reducing the possibility of uneven force when squeezing the asphalt mixture block and affecting the detection value.
[0011] Further, the synchronous movement component includes a bidirectional threaded rod arranged between the two second support plates. A rotating disc is rotatably connected to the bidirectional threaded rod, and the rotating disc is rotatably connected to the second support plates. Two symmetric moving plates are threadedly connected to the bidirectional threaded rod. The moving plates are fixedly connected to the alignment push plates, and the locking mechanism corresponds to the rotating disc.
[0012] By adopting the above technical solution, rotate the bidirectional threaded rod to make the moving plates on the bidirectional threaded rod move simultaneously, and the moving plates drive the alignment push plates to move simultaneously, so that it can be convenient for the alignment push plates to move towards the middle at the same time.
[0013] Further, limiting blocks are fixed on both of the rotating disks, and a limiting slide bar is fixed between the two limiting blocks. The limiting slide bar penetrates through the two moving plates and is slidably connected to the moving plates.
[0014] By adopting the above technical solution, the two moving plates are restricted by the limiting slide bar, so that the possibility of the moving plates shifting during movement can be reduced.
[0015] Further, the locking mechanism includes a support block fixed on the second support plate. The support block corresponds to the limiting block. A locking block is fixed on the support block. A locking rod is slidably connected to the locking block, and a locking hole is formed in the limiting block.
[0016] By adopting the above technical solution, the limiting block on the rotating disk abuts against the support block, and then the locking rod is inserted into the limiting block to prevent the rotating disk from rotating. Thus, when the alignment push plate is not in use, the alignment push plate can be conveniently retracted, the possibility of affecting the placement of the asphalt mixture block is reduced, and at the same time, the limiting block is conveniently fixed.
[0017] Further, a locking spring is arranged between the locking rod and the locking block, and both ends of the locking spring are fixedly connected to the locking rod and the locking block.
[0018] By adopting the above technical solution, after the locking rod is inserted into the limiting block, the locking spring restricts the locking rod, so that the possibility of the locking rod disengaging from the limiting block when the bidirectional threaded rod rotates can be reduced.
[0019] Further, a downward pressing inclined surface is formed at one end of the locking rod close to the locking hole, and the downward pressing inclined surface is inclined towards the limiting block.
[0020] By adopting the above technical solution, when the rotating disk drives the limiting block to rotate, the limiting block presses the downward pressing inclined surface on the locking rod, so that the locking rod can be conveniently inserted into the locking hole on the limiting block with the cooperation of the locking spring.
[0021] Further, a storage snap ring is fixed on the support frame, and one side of the storage snap ring is open.
[0022] By adopting the above technical solution, when the two alignment push plates are not in use, the rotating disk drives the bidirectional threaded rod, the limiting block, the limiting slide bar and the moving plate to maintain a vertically upward state, and the storage snap ring is used to clamp the limiting slide bar for restriction, so that the alignment push plate can be conveniently retracted when not in use.
[0023] To sum up, the present application includes at least one of the following beneficial effects;
[0024] 1. In this application, by keeping the rotating disk stationary, aligning the pushing plate on the moving plate towards the space between the clamping block 1 and the clamping block 2, then rotating the bidirectional threaded rod on the rotating disk, moving the two moving plates closer to the space between the clamping block 1 and the clamping block 2, and enabling the two moving plates to drive the aligning pushing plate to approach the asphalt mixture block between the clamping block 1 and the clamping block 2 under the restriction of the limit sliding rod. Under the restriction of the aligning pushing plate, the asphalt mixture block is positioned between the clamping block 1 and the clamping block 2, achieving the purpose of enabling the asphalt mixture block to be more accurately located at the middle position between the clamping block 1 and the clamping block 2 and reducing the possibility of uneven stress during the extrusion of the asphalt mixture block, which may affect the detection value.
[0025] 2. In this application, when the aligning pushing plate is needed, directly rotate the moving plate to drive the rotating disk and the limit sliding rod to disengage from the storage snap ring. Then, the limit block on the rotating disk abuts against the support block, keeping the limit sliding rod horizontal and the moving plate facing the clamping block 1 and the clamping block 2. When the limit block abuts against the support block, the limit block presses the downward inclined surface, causing the locking rod to slide on the locking block. When the locking hole on the limit block aligns with the locking rod, under the push of the locking spring, the locking rod enters the locking hole, preventing the limit block from moving. When the bidirectional threaded rod is rotated, the rotating disk and the limit sliding rod cannot move, achieving the purpose of being able to conveniently retract the aligning pushing plate when it is not in use, reducing the possibility of affecting the placement of the asphalt mixture block, and at the same time facilitating the fixation of the limit block, and keeping the rotating disk stationary when the bidirectional threaded rod is rotated.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1 —4 Provide further details of this application.
[0033] The embodiment of the present application discloses an asphalt mixture performance detection device.
[0034] Reference Figure 1 , Figure 2 and Figure 3 A device for testing the performance of asphalt mixture comprises a testing platform 1, a hydraulic telescopic rod 2 is fixed on the testing platform 1, a clamping block 3 is fixed on the telescopic end of the hydraulic telescopic rod 2, a clamping block 5 is arranged on the clamping block 3, the clamping block 3 and the clamping block 2 5 are both arc-shaped, two symmetrical sliding rods 4 are fixed on the clamping block 3, the sliding rod 4 passes through the clamping block 2 5 and is slidably connected with the clamping block 2 5, a distance measuring sensor 11 is fixed on the clamping block 2 5, the telescopic end of the distance measuring sensor is in conflict with the clamping block 1 3, a support frame 8 is fixed on the testing platform 1, a conflicting rod 9 is fixed on the support frame 8, a control computer 10 is fixed on one side of the testing platform 1, an alignment mechanism 6 is arranged on one side of the support frame 8, and a locking mechanism 7 is arranged on the support frame 8.
[0035] When the detection device needs to be used, first place the asphalt mixture module between the first clamping block 3 and the second clamping block 5, then move the alignment mechanism 6 to both ends of the asphalt mixture block clamped by the first clamping block 3 and the second clamping block 5, and then the alignment mechanism 6 approaches both ends of the asphalt mixture block simultaneously, so that the alignment mechanism 6 pushes both ends of the asphalt mixture block, making the asphalt mixture block located in the middle position clamped by the first clamping block 3 and the second clamping block 5. Then, use the locking mechanism 7 to release the lock on the alignment mechanism 6, and then retract the alignment mechanism 6. Then, use the control computer 10 to control the hydraulic telescopic rod 2 to raise the first clamping block 3 and the second clamping block 5, so that the abutting rod 9 abuts against the second clamping block 5, and the first clamping block 3 and the second clamping block 5 clamp the asphalt mixture block. At the same time, the distance measuring sensor 11 detects the moving distance between the first clamping block 3 and the second clamping block 5, and then the control computer 10 detects the extrusion force of the first clamping block 3 and the second clamping block 5 on the asphalt mixture block to complete the detection of the performance of the asphalt mixture block. By placing the asphalt mixture block between the first clamping block 3 and the second clamping block 5 and using the alignment mechanism 6 to push the asphalt mixture block, the asphalt mixture block can be more accurately located in the middle position between the first clamping block 3 and the second clamping block 5, reducing the possibility of uneven force when squeezing the asphalt mixture block and affecting the detection value.
[0036] Refer to Figure 2 、 Figure 3 and Figure 4 Figure, the alignment mechanism 6 includes two symmetrically fixed support plates 61 on the support frame 8, two support plates 62 are fixed on both support plates, two symmetric alignment push plates 63 are arranged between the two support plates 62, and a synchronous movement component 64 is arranged between the two alignment push plates 63 and the two support plates 62.
[0037] In addition, the synchronous movement component 64 includes a bidirectional threaded rod 642 arranged between the two support plates 62. The bidirectional threaded rod 642 is rotatably connected with a rotating disk 641, and the rotating disk 641 is rotatably connected with the support plate 62. Two symmetrically arranged moving plates 643 are threadedly connected to the bidirectional threaded rod 642, and the moving plates 643 are fixedly connected with the alignment push plates 63. The locking mechanism 7 corresponds to the rotating disk 641.
[0038] Moreover, limit blocks 644 are fixed on both rotating disks 641, a limit slide bar 645 is fixed between the two limit blocks 644, and the limit slide bar 645 penetrates through the two moving plates 643 and is slidably connected with the moving plates 643.
[0039] First, let the rotating disc 641 drive the limit block 644, the limit slide rod 645, the bidirectional threaded rod 642 and the moving plate 643 to rotate on the two support plates two 62. Then, use the locking mechanism 7 to fix the limit block 644, keep the rotating disc 641 stationary, and let the alignment push plate 63 on the moving plate 643 face towards the space between the clamping block one 3 and the clamping block two 5. Then rotate the bidirectional threaded rod 642 on the rotating disc 641 to move the two moving plates 643 closer to the space between the clamping block one 3 and the clamping block two 5. Let the two moving plates 643 drive the alignment push plate 63 to approach the asphalt mixture block between the clamping block one 3 and the clamping block two 5 simultaneously under the restriction of the limit slide rod 645. Under the restriction of the alignment push plate 63, make the asphalt mixture block located between the clamping block one 3 and the clamping block two 5. By moving the two moving plates 643 simultaneously on the bidirectional threaded rod 642, make the two alignment push plates 63 approach the asphalt mixture block between the clamping block one 3 and the clamping block two 5 simultaneously, so that the asphalt mixture block can be more accurately located at the middle position between the clamping block one 3 and the clamping block two 5, reducing the possibility of uneven force when squeezing the asphalt mixture block and affecting the test value.
[0040] Referring to Figure 2 and Figure 4 , the locking mechanism 7 includes a support block 71 fixed on the support plate two 62. The support block 71 corresponds to the limit block 644. A locking block 73 is fixed on the support block 71. A locking rod 72 is slidably connected to the locking block 73. A locking hole is formed on the limit block 644.
[0041] In addition, a locking spring 74 is arranged between the locking rod 72 and the locking block 73. Both ends of the locking spring 74 are fixedly connected to the locking rod 72 and the locking block 73.
[0042] Moreover, a downward pressing inclined surface 75 is formed at one end of the locking rod 72 close to the locking hole. The downward pressing inclined surface 75 is inclined towards the limit block 644.
[0043] Also, a storage clamping ring 76 is fixed on the support frame 8. One side of the storage clamping ring 76 is open.
[0044] When the two alignment push plates 63 are not in use, the rotating disc 641 drives the bidirectional threaded rod 642, the limit block 644, the limit slide rod 645 and the moving plate 643 to maintain a vertically upward state, and the storage snap ring 76 is used to block the limit slide rod 645 for limitation. When the alignment push plate 63 needs to be used, directly rotate the moving plate 643 to drive the rotating disc 641 and the limit slide rod 645 to disengage from the storage snap ring 76. Then, the limit block 644 on the rotating disc 641 abuts against the support block 71 to keep the limit slide rod 645 horizontal, and the moving plate 643 faces the first clamping block 3 and the second clamping block 5. When the limit block 644 abuts against the support block 71, the limit block 644 presses down the inclined surface 75, causing the locking rod 72 to slide on the locking block 73. When the locking hole on the limit block 644 is aligned with the locking rod 72, under the push of the locking spring 74, the locking rod 72 enters the locking hole, preventing the limit block 644 from moving. When the bidirectional threaded rod 642 is rotated, the rotating disc 641 and the limit slide rod 645 cannot move. By making the limit block 644 on the rotating disc 641 abut against the support block 71 and then using the locking rod 72 to limit the limit block 644, the locking rod 72 can release the limitation on the limit block 644 at the same time, and the limit slide rod 645 can be stuck on the storage snap ring 76. Thus, when the alignment push plate 63 is not in use, it is convenient to retract the alignment push plate 63, reducing the possibility of affecting the placement of the asphalt mixture block. At the same time, it is convenient to fix the limit block 644, and the purpose is to keep the rotating disc 641 stationary when the bidirectional threaded rod 642 is rotated.
[0045] Working principle: When the detection device needs to be used, first place the asphalt mixture module between the first clamping block 3 and the second clamping block 5. Then directly rotate the moving plate 643 to drive the rotating disk 641 and the limiting slide bar 645 to disengage from the storage snap ring 76. Then the limiting block 644 on the rotating disk 641 abuts against the support block 71 to keep the limiting slide bar 645 horizontal. Let the moving plate 643 face the first clamping block 3 and the second clamping block 5. When the limiting block 644 abuts against the support block 71, the limiting block 644 presses down the inclined surface 75 to make the locking rod 72 slide on the locking block 73. When the locking hole on the limiting block 644 aligns with the locking rod 72, under the push of the locking spring 74, the locking rod 72 enters the locking hole, making the limiting block 644 immovable. When the double-threaded rod 642 on the rotating disk 641 is rotated, the rotating disk 641 and the limiting slide bar 645 cannot move. Then rotate the double-threaded rod 642 on the rotating disk 641 to make the two moving plates 643 approach each other between the first clamping block 3 and the second clamping block 5. Let the two moving plates 643 drive the alignment push plate 63 to approach the asphalt mixture block between the first clamping block 3 and the second clamping block 5 under the restriction of the limiting slide bar 645. Under the restriction of the alignment push plate 63, make the asphalt mixture block located in the middle of the first clamping block 3 and the second clamping block 5. Then rotate the double-threaded rod 642 in the reverse direction to make the moving plate 643 drive the alignment push plate 63 away from the asphalt mixture block. Then use the control computer 10 to control the hydraulic telescopic rod 2 to make the first clamping block 3 and the second clamping block 5 rise, make the abutting rod 9 abut against the second clamping block 5, and make the first clamping block 3 and the second clamping block 5 clamp the asphalt mixture block. At the same time, the distance measuring sensor 11 detects the moving distance between the first clamping block 3 and the second clamping block 5, and then the control computer 10 detects the extrusion force of the first clamping block 3 and the second clamping block 5 on the asphalt mixture block to complete the performance detection of the asphalt mixture block.
