Description

Technical Field

[0001] The utility model belongs to the technical field of slump detection, and in particular relates to a concrete slump detection device. Background Art

[0002] Concrete slump mainly refers to the plasticization and pumpability of concrete. The factors affecting concrete slump mainly include gradation changes, water content, weighing deviation of scales, and the amount of admixtures. Other factors that are easily overlooked include cement temperature. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete. The traditional slump test is to pour concrete into a conical slump cone and tamp and smooth it, then pull out the cone, and calculate the height of the slump cone minus the height of the highest point of the concrete after collapse. After searching, it was found that the application number "202322213444.0" discloses a "concrete slump performance testing device", which records "including a slump testing platform, a slump cone; the slump testing platform is placed horizontally, the slump cone is set to a frustum-shaped structure and is placed horizontally on one side of the top of the slump testing platform, a circle of cone lower eaves is radially installed on the bottom of the circumferential side wall of the slump cone, and a plurality of slump cone positioning parts are evenly spaced on one side of the top of the cone lower eaves, and a group of lifting mechanisms are provided on the slump testing platform on one side of the slump cone, and the lifting mechanism rotates from top to bottom. The slump cone is automatically provided with a slump lifting assembly and a concrete slump height measuring assembly, and the slump lifting assembly is detachably connected to the top of the slump cone. When in use, the above detection device drives the screw rod through the motor so that the hook can stably pull up the slump cone and conveniently detect the slump of concrete through the steel tape measure. The above detection device can improve the slump detection efficiency and reduce the physical exertion of the staff. However, the above device still has certain shortcomings when in use: the structure of the above device is fixed installation. When the above device is idle, it occupies a large area and is not convenient for storage and placement. Although the above device can pull up the slump cone vertically when in use, it is necessary to first adjust the lifting plate to be just above the center of the slump cone when pulling up the slump cone. Otherwise, when pulling up the slump cone, the failure to pull up the slump cone vertically may affect the slump detection accuracy. This process is relatively cumbersome and complicated, which is not conducive to improving the slump detection efficiency. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-6 The utility model provides the following technical solutions: a concrete slump detection device, comprising a base plate 1, a servo motor 2 is fixedly connected to one end of the top of the base plate 1, the output shaft of the servo motor 2 is fixedly connected to the winding wheel 3, a mounting groove 4 is provided on the surface of the base plate 1, a bracket assembly 5 is installed in the mounting groove 4, a slump cone 6 is provided on the surface of the base plate 1, a handle 7 is rotatably connected to the top surface of the slump cone 6, a hanging ring 8 is fixedly connected to the surface of the handle 7, a first screw hole 9 is provided at the other end of the top of the base plate 1, a scale 10 is fixedly connected to the surface of the base plate 1 on one side of the first screw hole 9, and a measuring assembly 11 is installed in the first screw hole 9.

[0024] In this embodiment, the bracket assembly 5 includes a mounting plate 51 installed in the mounting groove 4, the top of the mounting plate 51 is fixedly connected to a support column 52, a crossbeam 53 is installed on one side of the top of the support column 52, the top of the support column 52 and one end of the top of the crossbeam 53 are fixedly connected to a pulley group 54, and a winding rope 12 is wound around the surface of the winding wheel 3. The winding rope 12 is arranged on the surface of the two pulley groups 54 and is connected to a hook 13 at the end.

[0025] Specifically, after installing the mounting plate 51 in the mounting groove 4, the winding rope 12 is passed around the pulley group 54 and then hung on the hanging ring 8 through the hook 13. Then, when the servo motor 2 drives the winding wheel 3 to reel in the winding rope 12, the hook 13 will pull up the slump cylinder 6, thereby facilitating the detection of the slump of the concrete.

[0026] In this embodiment, the crossbeam 53 and the support column 52 are hinged by a hinge 55. A first fixing hole 56 is opened in the middle of the crossbeam 53, and a second fixing hole 57 is opened at the top of the support column 52. When the first fixing hole 56 and the second fixing hole 57 are aligned, the crossbeam 53 and the support column 52 are vertical, and a fixing rod 58 is inserted and connected in the first fixing hole 56 and the second fixing hole 57.

[0027] Specifically, by rotating the crossbeam 53 so that it is perpendicular to the support column 52, the fixing rod 58 is inserted into the first fixing hole 56 and the second fixing hole 57, thereby fixing the position of the crossbeam 53. This allows the crossbeam 53 to be folded down when the device is idle, making it easier for the staff to store the device.

[0028] In this embodiment, connecting plates 14 are fixedly connected to both sides of the bottom of the collapse cylinder 6, two second screw holes 15 are opened on the surface of the bottom plate 1, and a guide hole 16 is opened on the surface of the connecting plate 14.

The guide rod 17 is threadedly connected to the second screw hole 15 through the threaded section.

[0029] Specifically, after the guide rod 17 is threadedly connected to the second screw hole 15, the guide hole 16 on the surface of the connecting plate 14 is inserted and connected to the guide rod 17, thereby facilitating the rapid positioning of the use position of the collapse cone 6. Moreover, when the collapse cone 6 is pulled upward, the collapse cone 6 can be kept pulled up vertically under the action of the guide rod 17, thereby avoiding the position of the collapse cone 6 being offset when it is pulled upward, affecting the accuracy of the concrete slump.

[0030] In this embodiment, a third screw hole 18 is provided on both sides of the mounting plate 51, and a fourth screw hole 19 is provided at the bottom end of the mounting groove 4. The mounting groove 4 and the base plate 1 are fixed by fixing bolts connected by the inner threads of the third screw hole 18 and the fourth screw hole 19.

[0031] Specifically, by installing the mounting plate 51 in the mounting groove 4 and then threading it with the third screw hole 18 and the fourth screw hole 19 through fixing bolts, it is convenient to fix the mounting plate 51. This installation method allows the bracket assembly 5 to be disassembled when the device is idle, making it easier for the staff to store and place the device.

[0032] In this embodiment, the measuring assembly 11 includes a guide column 111, a threaded section is provided at the bottom end of the guide column 111, and the guide column 111 is threadedly connected to the first screw hole 9 through the threaded section. An adjusting ring 112 is provided on the surface of the guide column 111, and the inner diameter of the adjusting ring 112 matches the diameter of the guide column 111. The adjusting ring 112 is fixedly connected to a connecting block 113 on the side close to the collapse cylinder 6, and a rotating groove 114 is provided on the surface of the connecting block 113, and a measuring plate 115 is rotatably connected in the rotating groove 114.

[0033] Specifically, after the slump cylinder 6 is pulled out, the concrete collapses under the action of its own weight. After the collapse is completed, the measuring plate 115 is rotated and the adjustment ring 112 is moved downward, so that the measuring plate 115 is located at the highest point of the concrete after the collapse. At this time, the slump of the concrete can be conveniently detected according to the scale 10.

[0034] In this embodiment, the side of the adjustment ring 112 away from the collapse cylinder 6 is fixedly connected to a fixed block 116, and a through groove 117 is provided on the surface of the fixed block 116. The scale 10 passes through the groove 117 and fits against the inner wall of one side of the groove 117. An adjustment rod 118 is inserted and connected to one side of the fixed block 116. One end of the adjustment rod 118 extends into the groove 117 and is fixedly connected to the anti-sliding block 119. The other end of the adjustment rod 118 is fixedly connected to a pulling block 1110. A spring 1111 is provided on the outside of the adjusting rod 118.

When the measuring plate 115 fits against the support block 1112, the measuring plate 115 and the guide column 111 are perpendicular.

[0035] Specifically, when the adjustment ring 112 is moved downward, the pull block 1110 is pulled outward so that the anti-slip block 119 is separated from the surface of the scale 10. When the measuring plate 115 contacts the highest point of the concrete after collapse, the pull block 1110 is released. Under the action of the spring 1111, the adjustment rod 118 drives the anti-slip block 119 to press against the scale 10, thereby fixing the position of the adjustment ring 112, and then facilitating the calculation and detection of the slump of the concrete according to the height of the fixing block 116 at the scale 10.

[0036] Working principle: The servo motor 2 drives the winding wheel 3 to rotate and reel in the winding rope 12, and then the winding rope 12 drives the hook 13 to pull up the slump cone 6 vertically. After pulling up, the slump of the concrete is detected by the set measuring component 11. Since the slump cone 6 can be pulled up vertically, the accuracy of the concrete slump detection can be effectively improved. At the same time, the bracket component 5 and the measuring component 11 can be disassembled, making the device easier to store and place.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
