Description

Technical Field

[0001] The present invention relates to the technical field of concrete slump detection, and specifically to a slump detection device for concrete. Background Art

[0002] The slump of concrete mainly refers to the plasticizing performance and pumpability of concrete. The factors affecting the slump of concrete mainly include gradation changes, water content, weighing deviation of weighing instruments, dosage of admixtures, and what is easily overlooked is also the temperature of cement, etc. The slump refers to the workability of concrete. Specifically, it ensures the normal progress of construction, including the water retention, fluidity and cohesion of concrete.

[0003] Publication No. CN215768597U discloses a slump detection device for concrete. By arranging a plurality of contact blocks at the bottom of the slump bucket, the movable rod inside the contact block is on the same horizontal line as the limiting ring. The spring on the outer wall of the movable rod presses against the limiting ring, so that the movable rod and the contact block support and adjust the height. When the user uses it on an uneven ground, it does not affect the lifting of the bucket, and the slump phenomenon of concrete caused by its own weight changes. By arranging an inner cover inside the slump bucket, when filling concrete, by placing the inner cover inside the slump bucket, and the bottom of the drainage cover is clamped with the sealing ring on the top of the inner cover, when the whole device fills concrete, the concrete accumulates inside the inner cover. At the same time, when the whole device lifts the bucket, it needs to be unfolded and lifted twice to avoid the first lifting of the bucket. Because the lifting of the bucket is easy to be operated improperly, it affects the slump detection of concrete after lifting the bucket. By taking out the slump bucket for the first time and then unfolding the inner cover again, in order to detect the slump of concrete. However, the following problems still exist in the actual use of this patent: Although the slump detection device for concrete can realize the slump detection of concrete, when detecting the slump of concrete, the concrete mixture is loaded into the slump bucket in three times. After each loading, it is tamped 25 times along the spiral direction from the outside to the inside with a tamper to ensure that the concrete is evenly tamped. After the top layer is tamped, it is leveled with a trowel to make it flush with the top of the bucket. In the prior art, generally, a tamper is used manually for tamping, which not only increases the labor intensity of workers, but also because the slump detection bucket is a conical bucket with a smaller upper part and a larger lower part, when manually tamping the concrete, the tamping is not standardized and cannot be tamped along the spiral direction, which affects the tamping effect of the concrete and thus affects the detection effect of the concrete slump.

[0004] Therefore, a slump detection device for concrete is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The object of the present invention is to provide a slump detection device for concrete, so as to solve the problem proposed in the above background technology that when detecting the slump of concrete, the concrete mixture is loaded into the slump bucket in three times.

After tamping the top layer, use a trowel to level the surface to make it flush with the top of the bucket. In the prior art, tamping is generally carried out manually with a tamper, which not only increases the labor intensity of workers, but also because the slump detection bucket is a conical bucket with a smaller upper part and a thicker lower part, there are non-standard tamping operations when manually tamping the concrete, and it is impossible to tamp along the spiral direction, affecting the tamping effect of the concrete, and thus affecting the slump detection effect of the concrete.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: For this slump detection device for concrete, since the concrete mixture is filled into the slump bucket in three times, and each time after filling, it is tamped 25 times along the spiral direction from the outside to the inside with a tamping rod. Therefore, by changing the tamping amplitude, it adapts to the concrete poured into the slump bucket three times, improving the uniformity of concrete tamping. By rotating the second knob to drive the support threaded rod to rotate, the height of the support chassis is increased, facilitating the adjustment of the flatness of the mobile base and facilitating the slump detection. The universal wheels facilitate the movement of the entire detection device, and during the concrete pouring, the entire device can be moved beside the concrete mixer truck for concrete slump detection. The specific content is as follows: 1. By setting up the detection and compaction mechanism, not only can the first rotating motor drive the first rotating worm to rotate, and by utilizing the meshing connection between the first rotating worm and the first rotating worm gear, the first rotating worm gear drives the first adjusting disk to rotate. At the same time, start the first adjusting motor to drive the first adjusting screw rod to rotate, so that the first adjusting thread sleeve drives the first limiting disk and the second rotating bracket to move, and the position of the compaction rod can be changed. Start the second rotating motor to drive the rotating plate and the reciprocating bracket to rotate, start the third rotating motor to drive the third rotating worm to rotate, and by utilizing the meshing connection between the third rotating worm and the third rotating worm gear, the third rotating worm gear drives the second adjusting disk to rotate. Start the second adjusting motor to drive the second adjusting screw rod to rotate, so that the second adjusting thread sleeve drives the reciprocating limiting block to move. By utilizing the sliding connection between the reciprocating sliding frame and the reciprocating limiting block, the reciprocating sliding frame drives the reciprocating gear to rotate. By utilizing the meshing connection between the reciprocating rack and the reciprocating gear, the reciprocating rack can slide inside the reciprocating limiting groove. The reciprocating rack drives the mounting sleeve and the compaction rod to reciprocate, thereby compacting the concrete. By adjusting the position of the reciprocating limiting block, the rotation radius of the reciprocating limiting block can be changed, and the reciprocating frequency of the reciprocating sliding frame can be adjusted, thereby changing the compaction amplitude of the compaction rod. Since the concrete mixture is loaded into the slump cone in three times, and after each loading, the compaction rod is used to compact 25 times in a spiral direction from the outside to the inside. Therefore, by changing the compaction amplitude, it can adapt to the concrete poured into the slump cone three times, and improve the uniformity of concrete compaction. By changing the angle and position of the compaction rod, it is convenient for the compaction rod to compact the concrete in a spiral direction from the outside to the inside. By rotating the compaction rod, the mounting block can cross over the spring catch and slide out from the horizontal rotating groove and the vertical mounting groove, which is convenient for the installation and disassembly of the compaction rod, and convenient for cleaning the compaction rod, avoiding adhesion of a certain amount of concrete on the compaction rod, which affects the subsequent concrete slump test. Start the lifting motor to drive the lifting rotating rod and the bevel gear transmission assembly to rotate, so that the bevel gear transmission assembly drives the lifting screw rod to rotate. At the same time, the lifting thread sleeve drives the clamping bracket to move up and down. Start the clamping motor to drive the first sprocket transmission assembly and the clamping bidirectional screw rod to rotate, so that the clamping thread sleeve drives the clamping arms to move relatively. The clamping arms clamp the lifting handle and lift the test conical bucket, move the clamping arms to the top of the concrete, and detect the slump through the scale; 2. By setting up the detection and fixing mechanism, not only can the feed hopper be placed on the top of the detection conical barrel, and the installation hook and the installation card slot can be engaged by rotating the feed hopper, so as to realize the fixation of the feed hopper, which is convenient for pouring concrete into the detection conical barrel. By rotating the adjustment knob to drive the third adjustment threaded rod to rotate, the third adjustment threaded sleeve drives the rotating support to move up and down, and the height of the fixed pressing plate can be adjusted. By loosening the locking bolt and rotating the fixed support, under the action of the fixed sliding rod and the fixed sliding sleeve, the fixed pressing plate rotates to the surface of the detection conical barrel, and the locking bolt is fixed, so as to clamp and fix the detection conical barrel, improving the stability of concrete ramming. By starting the longitudinal motor to drive the second sprocket transmission assembly and the longitudinal threaded rod to rotate, the longitudinal threaded sleeve drives the lifting support to move longitudinally, which is convenient for cleaning the concrete. By rotating the second knob to drive the support threaded rod to rotate, the height of the support chassis is increased, which is convenient for adjusting the flatness of the moving base and facilitating the slump test. The whole detection device can be moved conveniently through the universal wheels, and when pouring concrete, the whole device can be moved beside the concrete mixer truck for the slump test of concrete.

Under the action of the fixed sliding rod 216 and the fixed sliding sleeve 217, the fixed pressing plate 220 rotates to the surface of the detection conical barrel 202, and fix the locking bolt 214, thereby clamping and fixing the detection conical barrel 202 and improving the stability of concrete ramming.

[0023] Please refer to Figures 8 - 11, a sprocket limiting cover 221 is fixedly installed on the front of the mobile base 201. On one side inside the sprocket limiting cover 221, a longitudinal motor 222 is fixedly installed. The output end of the longitudinal motor 222 is fixedly connected to a second sprocket transmission assembly 223. On one side of the second sprocket transmission assembly 223, longitudinal threaded rods 224 are symmetrically installed. Longitudinal threaded sleeves 225 are threadedly connected to the outer sides of the two longitudinal threaded rods 224. The longitudinal threaded sleeves 225 are fixedly installed at the bottom of the lifting bracket 137. Support threaded rods 226 are threadedly connected to the four surrounding areas inside the mobile base 201. The top of the support threaded rod 226 is fixedly installed with a second knob 227. The bottom of the support threaded rod 226 is rotatably connected to a support chassis 228. Universal wheels 229 are fixedly installed around the bottom of the mobile base 201. By starting the longitudinal motor 222 to drive the second sprocket transmission assembly 223 and the longitudinal threaded rods 224 to rotate, the longitudinal threaded sleeves 225 drive the lifting bracket 137 to move longitudinally, facilitating the cleaning of the concrete. By rotating the second knob 227 to drive the support threaded rod 226 to rotate, the height of the support chassis 228 is increased, facilitating the adjustment of the flatness of the mobile base 201 and facilitating the detection of the slump. The universal wheels 229 facilitate the movement of the entire detection device, enabling the entire device to be moved to the side of the concrete mixer truck for the detection of the concrete slump during the pouring of concrete.

[0024] Working principle: Before using this slump detection device for concrete, it is necessary to first check the overall condition of the device to ensure that it can work normally. According to Figure 1 - Figure 11As shown in the figure, first, place the feed hopper 206 on the top of the test conical bucket 202. Rotate the feed hopper 206 to engage the mounting hook 207 with the mounting slot 205, thereby fixing the feed hopper 206, which is convenient for pouring concrete into the test conical bucket 202. Rotate the adjustment knob 210 to drive the third adjustment screw rod 211 to rotate, so that the third adjustment screw sleeve 212 drives the rotating support 213 to move up and down, and the height of the fixed pressing plate 220 can be adjusted. Loosen the locking bolt 214 and rotate the fixed bracket 215. Under the action of the fixed sliding rod 216 and the fixed sliding sleeve 217, the fixed pressing plate 220 is rotated to the surface of the test conical bucket 202, and the locking bolt 214 is fixed, thereby clamping and fixing the test conical bucket 202, improving the stability of concrete tamping. Start the longitudinal motor 222 to drive the second sprocket transmission assembly 223 and the longitudinal screw rod 224 to rotate, so that the longitudinal screw sleeve 225 drives the lifting bracket 137 to move longitudinally, which is convenient for cleaning the concrete. Rotate the second knob 227 to drive the support screw rod 226 to rotate, thereby increasing the height of the support chassis 228, facilitating the adjustment of the flatness of the moving base 201, and facilitating the slump test. The universal wheels 229 facilitate the movement of the entire testing device, and the entire device can be moved to the side of the concrete mixer truck for concrete slump testing during concrete pouring.

[0025] Secondly, drive the first rotating worm 103 to rotate by using the first rotating motor 102. Utilize the meshing connection between the first rotating worm 103 and the first rotating worm gear 104 to make the first rotating worm gear 104 drive the first adjusting disk 105 to rotate. At the same time, start the first adjusting motor 106 to drive the first adjusting threaded rod 107 to rotate, so that the first adjusting threaded sleeve 108 drives the first limiting disk 109 and the second rotating bracket 110 to move, which can change the position of the ramming rod 134. Start the second rotating motor 111 to drive the rotating plate 112 and the reciprocating bracket 113 to rotate. Start the third rotating motor 115 to drive the third rotating worm 116 to rotate. Utilize the meshing connection between the third rotating worm 116 and the third rotating worm gear 117 to make the third rotating worm gear 117 drive the second adjusting disk 118 to rotate. Start the second adjusting motor 119 to drive the second adjusting threaded rod 120 to rotate, so that the second adjusting threaded sleeve 121 drives the reciprocating limiting block 122 to move. Utilize the sliding connection between the reciprocating sliding frame 123 and the reciprocating limiting block 122 to make the reciprocating sliding frame 123 drive the reciprocating gear 124 to rotate. Utilize the meshing connection between the reciprocating rack 126 and the reciprocating gear 124 to enable the reciprocating rack 126 to slide inside the reciprocating limiting groove 127. Drive the mounting sleeve 128 and the ramming rod 134 to reciprocate through the reciprocating rack 126, thereby ramming the concrete. By adjusting the position of the reciprocating limiting block 122, the rotation radius of the reciprocating limiting block 122 can be changed, and the reciprocating frequency of the reciprocating sliding frame 123 can be adjusted, thereby changing the ramming amplitude of the ramming rod 134. Since the concrete mixture is loaded into the slump bucket in three times, and after each loading, the ramming rod 134 is used to ram 25 times from the outside to the inside along the spiral direction. Therefore, by changing the ramming amplitude, it can adapt to the concrete poured into the slump bucket three times and improve the uniformity of concrete ramming. By changing the angle and position of the ramming rod 134, it is convenient for the ramming rod 134 to ram the concrete from the outside to the inside along the spiral direction.

[0026] Finally, by rotating the ramming rod 134, the mounting block 136 is moved over the spring catch 131 and slides out from the horizontal rotating groove 130 and the vertical mounting groove 129, facilitating the installation and removal of the ramming rod 134 and the cleaning of the ramming rod 134, avoiding adhesion of a certain amount of concrete to the ramming rod 134, which may affect the subsequent slump test of the concrete. Start the lifting motor 139 to drive the lifting rotating rod 140 and the bevel gear transmission assembly 141 to rotate, so that the bevel gear transmission assembly 141 drives the lifting threaded rod 142 to rotate. At the same time, the lifting threaded sleeve 143 drives the clamping bracket 144 to move up and down. Start the clamping motor 145 to drive the first sprocket transmission assembly 146 and the clamping bidirectional threaded rod 147 to rotate, so that the clamping threaded sleeve 148 drives the clamping arms 149 to move relatively. Clamp the lifting handle 204 by the clamping arms 149 and lift the test conical bucket 202. Move the clamping arms 149 to the top of the concrete and perform the slump test through the scale 138.
