[0035] See also Figures 1 to 9As shown, a slump detection device for highway construction comprises a test bench 1, a locking mechanism 2 and a synchronization mechanism 3; the test bench 1 is cylindrical, and two guide rails 11 are mirror-imaged at the top edge of the test bench, and a sliding block 111 is slidably arranged in each guide rail 11, and horizontal plates 112 are arranged on the opposite sides of the two sliding blocks 111, and the ends of the two horizontal plates 112 close to each other are connected to each other through a fixing ring 113, and a conical cylinder 12 is arranged at the bottom center of the fixing ring 113; a detection rod 13 is also arranged at the top edge of the test bench 1, and a measuring plate 131 is sleeved on the detection rod 13, and a naughty plate is also arranged on the outer wall of the test bench 1, and a level bubble 15 is arranged on the adjustment plate 14; the outer wall of the test bench 1 is circumferentially Three extension plates 16 are provided, each of which is provided with a sliding hole 161, and a support column 17 is slidably provided in each sliding hole 161. There are multiple groups of locking mechanisms 2, which are provided on the corresponding extension plates 16 and can lock the corresponding support column 17 when the experimental table 1 is horizontal; two mounting plates 162 extending vertically downward are provided at the bottom of each extension plate 16, and the two mounting plates 162 are located between the corresponding support column 17 and the outer wall of the experimental table 1, and each mounting plate 162 is provided with a rotating hole 1621, and each group of locking mechanisms 2 includes two rotating rods 21 rotatably provided in the corresponding rotating holes 1621, and a pressing block 22 is provided at one end of each rotating rod 21 close to the support column 17;

[0036] The synchronization mechanism 3 is disposed on the experimental platform 1 and can make the plurality of rotating rods 21 rotate synchronously.

[0037] Due to the complicated ground conditions on site, the staff placed the test bench 1 on the ground. At this time, the support column 17 arranged on the extension plate 16 was able to contact the ground. Subsequently, the positions of the three support columns 17 were leveled through the level bubble 15, so that the level bubble 15 was in a centered state to ensure the accuracy of the slump test; limit disks were provided at both ends of the support column 17 to prevent the support column 17 from falling off the extension plate 16; after the adjustment was completed, the multiple rotating rods 21 were adjusted through the synchronization mechanism 3, and the two rotating rods 21 located on the same extension plate 16 could rotate synchronously, so that the clamping block 22 at the end of the rotating rod 21 could move toward the direction close to the corresponding support rod. , so that the clamping block 22 can fit with the support column 17, thereby limiting the position of the support column 17 and ensuring the stability of the test bench 1 during the slump test; then, move the conical cylinder 12 to the center of the test bench 1 and fit it to the surface of the test bench 1, the opening of the fixing ring 113 is connected inside the conical cylinder 12, and concrete is filled into the conical cylinder 12 through the opening of the fixing ring 113. After the filling is completed, the staff grabs the corresponding horizontal plates 112 with both hands, and with the cooperation of the guide rail 11, the conical cylinder 12 can be lifted upward at a uniform speed, so that the concrete collapses naturally. After the collapse is completed, the highest point of the collapse is measured by the measuring plate 131, thereby completing the detection work.

[0038] See also Figures 3 to 5 As shown, the synchronization mechanism 3 includes a pushing ring 31, a moving bar 32 and a rotating ring 33; the pushing ring 31 is coaxially arranged on the outer wall of the bottom of the experimental table 1, and three moving bars 32 extending vertically upward are circumferentially arranged on the top of the pushing ring 31, and each extension plate 16 is provided with a guide groove 163 for the moving bar 32 to pass through, and the moving bar 32 is slidably arranged in the corresponding moving groove, and a synchronous gear 23 is arranged at one end of each rotating rod 21 away from the clamping block 22, and the moving bar 32 is located between the two synchronous gears 23, and the moving bar 32 is equidistantly arranged on both sides of the length direction. A plurality of tooth grooves 321 are meshed with the corresponding synchronous gears 23; a plurality of L-shaped blocks 18 are arranged at the bottom edge of the experimental table 1, and the rotating ring 33 is coaxially rotatably arranged inside the pushing ring 31, and a plurality of L-shaped grooves 34 cooperating with the L-shaped blocks 18 are arranged on the top of the rotating ring 33 along the axial direction.

[0039] The staff lifts the experimental table 1 and sets the experimental table 1 in a horizontal state by observing the level bubble 15. After the experimental table 1 is horizontal, the staff pulls the push ring 31 upward with both hands, so that the moving bar 32 on the push ring 31 can contact the corresponding synchronous gear 23, thereby driving the corresponding two rotating rods 21 to rotate, so that the clamping block 22 can contact the support column 17. At this time, the L-shaped block 18 extends into the L-shaped slot 34. A plurality of semicircular protrusions are provided at the bottom of the rotating ring 33, so that the staff can rotate the rotating ring 33 conveniently. Subsequently, by adjusting the rotating ring 33, the L-shaped block 18 can be engaged with the L-shaped slot 34, thereby locking the position of the push ring 31 to prevent it from moving and causing the experimental table 1 to shake.

[0040] See also Figure 3 As shown, each rotating rod 21 is also sleeved with a return torsion spring 24 , and each moving bar 32 is also provided with an interception plate 322 at the top.

[0041] In order to ensure the smooth movement of the support column 17, a return torsion spring 24 is provided. After the push ring 31 is unlocked, the two clamping blocks 22 can be separated from each other, thereby preventing the clamping blocks 22 from affecting the movement of the support column 17. An intercepting plate 322 is provided at the end of the moving bar 32 to prevent the push ring 31 from falling off.

[0042] See also Figure 1 , Figure 2 and Figure 6 As shown, a through hole 19 is provided at the center of the experimental table 1, a flip plate 191 is provided in the through hole 19, a hinge rod 1911 is provided on the outer wall of the flip plate 191 in a mirror image, a hinge hole 192 is provided on the inner wall of the through hole 19 in a mirror image, the hinge rod 1911 is rotatably provided in the corresponding hinge hole 192, a horizontal torsion spring 1912 is provided at one end of each hinge rod 1911 extending out of the through hole 19, and a flip mechanism 4 is provided on each horizontal plate 112, which can rotate the flip plate 191 as the horizontal plate 112 moves.

[0043] Since the slump test needs to be carried out multiple times to ensure the accuracy of the experimental data, the concrete needs to be processed after each experiment. Based on this situation, a flip plate 191 is arranged at the center of the test bench 1. Under the torsion of the horizontal torsion spring 1912, the flip plate 191 maintains a state parallel to the surface of the test bench 1. After the experiment is completed, the horizontal plate 112 is moved to rotate the flip plate 191 along the axis of the hinged rod 1911, so that the concrete remaining on the flip plate 191 is dumped, which facilitates the subsequent slump test and improves the test efficiency.

[0044] See also Figure 6As shown, the flipping mechanism 4 includes a vertical bar 41 and a friction block 42; a friction wheel 1913 is also provided on each hinged rod 1911, and the friction wheel 1913 is located between the corresponding flipping plate 191 and the inner wall of the perforation 19 of the laboratory table 1, and the vertical bar 41 is arranged at the bottom of the corresponding horizontal plate 112, and a friction block 42 cooperating with the friction wheel 1913 is provided at one end of the vertical bar 41 away from the horizontal plate 112.

[0045] As the conical cylinder 12 moves, the concrete collapses. Subsequently, the staff measures the slump. After the measurement is completed, the staff pulls the horizontal plate 112 to continue moving, so that the friction block 42 can contact the friction wheel 1913, so that the flip plate 191 flips multiple times, thereby pouring the concrete. After the pouring is completed, the staff moves the horizontal plate 112 toward the direction close to the test bench 1. At this time, the friction wheel 1913 separates from the friction block 42, and under the torsion of the horizontal torsion spring 1912, the flip plate 191 is reset, thereby facilitating the subsequent slump test.

[0046] See also Figure 8 and Fig. 9 As shown, each horizontal plate 112 is also provided with a fixing mechanism 5 for locking the position of the sliding block 111; each set of fixing mechanisms 5 includes a pressing bar 51 and a locking spring 52; each horizontal plate 112 is provided with pressing grooves 114 on both sides along the length direction, and there are two pressing bars 51, which are slidably arranged in the corresponding pressing grooves 114, and each pressing bar 51 is provided with a rubber block 511 at one end close to the sliding block 111, and each sliding block 111 is provided with a notch 115 for avoiding the rubber block 511, and each pressing bar 51 is connected to the inner wall at the bottom of the corresponding pressing groove 114 through a locking spring 52.

[0047] Since the conical cylinder 12 is not fixed after being lifted, another staff member is needed to perform slump detection at this time. In order to improve the convenience during the slump test, the rubber block 511 is able to fit tightly against the inner wall of the corresponding guide rail 11 through the locking spring 52, so that the conical cylinder 12 can be fixed at the corresponding height, which is convenient for the staff to measure the slump. After the detection is completed, the conical cylinder 12 is continued to be pulled upwards, so as to flip the flip plate 191, so as to pour the measured concrete, which is convenient for the subsequent slump test.

[0048] See also Figure 1 As shown, each fixing ring 113 is provided with a material gathering port 116 in an inverted cone shape.

[0049] The material collecting port 116 is provided to facilitate workers to introduce concrete into the conical cylinder 12 to prevent concrete from scattering.
