Description

Technical Field

[0001] The invention belongs to the technical field of concrete flow characteristic detection, and in particular relates to a concrete slump detection device for engineering road construction. Background Art

[0002] The purpose of concrete slump detection is to measure the working properties of concrete such as fluidity, plasticity and workability. By measuring the slump value, it can be judged whether the concrete meets the construction requirements, such as whether it is convenient for construction operations such as pumping, pouring and vibration, thereby ensuring the quality of the concrete structure during the construction process. For example, a concrete slump detection device for engineering road construction is proposed in patent announcement number CN114354447A.

[0003] When testing the slump of concrete, it is necessary to vibrate the concrete with a tamping rod to expel the air inside the concrete. At the same time, the vibration of the tamping rod will be transmitted to the concrete, causing the concrete particles to vibrate and squeeze and move each other, thereby prompting the various components to be more evenly distributed in the slump cone, so that the entire concrete forms a relatively dense state in the cone, which is helpful for the subsequent accurate measurement of the slump. The existing vibration work is usually performed manually. During the manual vibration process, the concrete is not vibrated enough, resulting in more gaps in the concrete, and the combination between coarse aggregate, fine aggregate and cement slurry is not tight enough, resulting in the concrete density not meeting the requirements; and excessive tamping makes the concrete too dense in the slump cone, and its original fluidity characteristics are changed, which in turn affects the accurate judgment of whether the concrete mix ratio is appropriate and whether it meets the construction requirements.

[0024] The operating principle of the present invention is now described as follows: a control signal is transmitted to the PLC controller 8 through the control box 7. After receiving the control signal, the PLC controller 8 first controls the third linear motor 181 to work, and the third linear motor 181 drives the clamping frame 19 to move through the bending rod 182. The clamping frame 19 drives the moving vehicle 5 to move through the positioning electric push rod 23 and the positioning seat 24 below, and drives the slump cone 6 to move to the left together through the small electric push rod 20 and the clamping plate 21, so that the moving vehicle 5 and the slump cone 6 move to the left together to the set position, and then the operator uses external equipment (such as a shovel) to transport a proper amount of concrete into the slump cone 6 for storage, and then uses a hard scraper to scrape the concrete that emerges from the outlet of the slump cone 6. Then the operator transmits a start signal to the PLC controller 8 through the control box 7. After receiving the electrical signal, the PLC controller 8 first controls the third linear motor 181 to work. The third linear motor 181 drives the moving vehicle 5 and the slump cone 6 to move rightward to the initial position, so that the slump cone 6 is located below the vibrating rod 14. Then the PLC controller 8 controls the second linear motor 12 to work reciprocatingly, and controls the angle motor 112 to work at a slower frequency. The second linear motor 12 drives the sleeve 13 and the vibrating rod 14 to move downward together, and the vibrating rod 14 is inserted into the slump cone 6. The air inside the concrete is discharged by the vibrating rod 14, and at the same time, the concrete particles are vibrated and squeezed and moved against each other, so that the various components are more evenly distributed in the slump cone 6, and the fluidity, compactness and other properties of the concrete are improved. In addition, the angle motor 112 drives the vibrating rod 14 to rotate in a circle along the inlet direction of the slump cone 6, so as to improve the uniformity of concrete vibration. When the concrete is vibrated to a suitable range, the density of the concrete will gradually increase, and the resistance encountered by the vibrating rod 14 when inserted into the concrete will also increase accordingly. The vibrating rod 14 will drive the lifting plate 15 to overcome the elastic force of the upper spring and move a longer distance. The lifting plate 15 will drive the conductive frame 16 to move upward and contact the conductive plate 17. The conductive frame 16 is electrically connected to the external power supply, and the conductive plate 17 is electrically connected to the PLC controller 8. When the conductive frame 16 and the conductive plate 17 are in contact, an electrical signal will be transmitted to the PLC controller 8. After receiving the electrical signal, the PLC controller 8 will first control the second linear motor 12 to drive the vibrating rod 14 to move upward and return to its original position, and then the PLC controller 8 will control The first linear motor 111 works, driving the vibrating rod 14 to move to the left to the set position, and then the PLC controller 8 controls the first electric push rod 9 to work, and the first electric push rod 9 drives the third linear motor 181 and the bending rod 182 to move upward together, and the bending rod 182 drives the clamping frame 19 to move upward, and the clamping frame 19 drives the slump cone 6 to move upward evenly through the small electric push rod 20 and the clamping plate 21, and separates the concrete and the slump cone 6 with uniform force, so that the concrete collapses naturally according to its own characteristics, forming a relatively regular and stable collapse shape, which can truly reflect the working performance of the concrete such as fluidity, plasticity and workability, and provide a reliable basis for judging whether the concrete meets the construction requirements; Then the PLC controller 8 drives the control motor 2 to work, and the control motor 2 (the control motor 2 is a brake motor) drives the rotating plate 4 to rotate 180 degrees through the rotating rod 3, so that the detection component 25 moves to the outside of the concrete. Then the PLC controller 8 controls the fourth linear motor 251 to work, and controls the laser generator 26 to work at the same time. The fourth linear motor 251 drives the detection frame 252 to move back and forth left and right. At the same time, the PLC controller 8 also controls the second electric push rod 10 to work (while controlling the second electric push rod 10 to work, the PLC controller 8 will also control the corresponding two limit electric push rods 33 to work through the trigger block 37 and the trigger plate 39, so that the limit electric push rod 33 drives the positioning plate 34 and the rough plate 35 to separate, and the corresponding sliding block 29 will drive the pointer plate 31 to move downward together with the fourth linear motor 251) When the fourth linear motor 251 drives the detection frame 252 to move once, the second electric push rod 10 drives the fourth linear motor 251 and the detection frame 252 to move downward by 1 mm. When the second electric push rod 10 drives the detection frame 252 to move downward by a certain distance, the light signal emitted by the laser generator 26 will be blocked by the highest point of the naturally collapsed concrete. When the laser receiver 27 cannot receive the laser signal from the laser generator 26, the PLC controller 8 will control the second electric push rod 10 to stop working immediately, and will also control the corresponding two limit electric push rods 33 to work, so that the limit electric push rod 33 drives the positioning plate 34 to contact the rough plate 35, so that the pointer plate 31 stays at a certain position of the scale 32. At this time, the position specified by the pointer plate 31 will be the slump of the concrete. When the slump detection of one type of concrete is completed, the PLC controller 8 controls the fifth linear motor 281 to work, and the fifth linear motor 281 drives the display panel 282 to move a certain distance through the bracket, so that the baffle 36 moves to the bottom of another horizontal plate 38, and then the PLC controller 8 controls the second electric push rod 10 to drive the fourth linear motor 251 to move upward to the set position, so that the fourth linear motor 251 drives the baffle 36 to move to the bottom of another horizontal plate 38 to wait for the next type of concrete slump detection; When the slump of all concretes has been detected, the PLC controller 8 will control the winding motor 42 to work until the set time, and at the same time control all the limit electric push rods 33 to drive the positioning plate 34 to retract to the initial position (the PLC controller 8 is electrically connected to the limit electric push rod 33 through components such as a conductive slide plate), and the winding motor 42 controls the rope drum 41 to work, and uses the pull rope 43 on the winding surface of the rope drum 41 to drive the reset plate 44 to move upward together, and through the reset plate 44 drives the pointer plate 31 and all the sliding blocks 29 to move upward to the set position together, and then the PLC controller 8 controls all the limit electric push rods 33 to work, and fixes the position of the sliding block 29 and the pointer plate 31 through the friction between the positioning plate 34 and the rough plate 35.
