Specific implementation manner
[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figures 1-5 , an embodiment provided by the present utility model: including a measuring frame 1, a measuring plate 2 is arranged inside the measuring frame 1, the front side of the measuring plate 2 is rotatably installed on the inner wall of the measuring frame 1 through a shaft pin, a measuring component 3 for measuring the angle of the measuring plate 2 is arranged on one side of the measuring frame 1, a fixed plate 4 is fixedly installed inside the measuring frame 1, a placing plate 5 is fixedly installed inside the measuring frame 1, and a limiting component 6 for limiting the measuring frame 1 is arranged on the top of the placing plate 5. First, move the measuring frame 1 to the concrete to be measured, and then the limiting component 6 can be used to limit the measuring frame 1 at this time. When the measuring frame 1 is fixed, the measuring plate 2 can be contacted with the concrete at this time, and the collapse angle of the concrete can be known by observing the measuring component 3 at this time.
[0031] Refer to Figures 1-5, the measuring component 3 includes a pointer 31. A rotating rod 32 is fixedly installed on the back surface of the measuring plate 2. The back surface of the rotating rod 32 penetrates to the rear side of the measuring frame 1 and is fixedly installed with the front side of the pointer 31. An arc protractor 33 is fixedly installed on the back surface of the fixing plate 4. Through the mutual cooperation of the pointer 31, the rotating rod 32 and the arc protractor 33, when the measuring plate 2 contacts the concrete, at this time, the measuring plate 2 will drive the rotating rod 32 and the pointer 31 to rotate. At this time, the angle corresponding to the pointer 31 on the arc protractor 33 can be observed, so as to know the slump angle of the concrete.
[0032] Refer to Figures 1-5, the limiting component 6 includes two groups of screw rods 61. A worm gear 62 is fixedly installed on the surface of the screw rod 61. Two groups of worm shafts 63 are arranged on the top of the placing plate 5. The worm shaft 63 meshes with the worm gear 62. A connecting rod 64 is arranged on the top of the placing plate 5. The back of the connecting rod 64 is fixedly installed with the front side of one group of worm shafts 63. The front end of the connecting rod 64 penetrates to the front end of the other group of worm shafts 63. The bottom of the screw rod 61 penetrates to the bottom of the placing plate 5 and is threadedly installed with the screw rod 61. Through the mutual cooperation of the screw rod 61, the worm gear 62, the worm shaft 63 and the connecting rod 64, when the connecting rod 64 is rotated, the worm shaft 63 can be driven to rotate. The rotation of the screw rod 61 drives the worm gear 62 to rotate. The rotation of the worm gear 62 drives the screw rod 61 to rotate. The rotation of the screw rod 61 will gradually move downward, so that the screw rod 61 will enter the ground, thereby limiting the measurement frame 1. U-shaped bases 65 are fixedly installed on both sides of the top of the placing plate 5. A U-shaped frame 66 is arranged on the top of the placing plate 5. The top of the screw rod 61 is rotationally installed with the top of the inner wall of the U-shaped frame 66 through a bearing. The back of one group of worm shafts 63 is rotationally installed with the rear side of the inner wall of the U-shaped frame 66 through a bearing. Through the mutual cooperation of the U-shaped base 65 and the U-shaped frame 66, when the screw rod 61 moves downward, the U-shaped frame 66 can be driven to move downward. The downward movement of the U-shaped frame 66 will slide inside the U-shaped base 65, thereby limiting the measurement frame 1. A rotating ring 7 is fixedly installed on the surface of the connecting rod 64. A rotating block 8 is fixedly installed on the surface of the rotating ring 7. Through the mutual cooperation of the rotating ring 7 and the rotating block 8, when the rotating block 8 is rotated, the rotating ring 7 can be driven to rotate. The rotation of the rotating ring 7 drives the connecting rod 64 to rotate. The rotation of the connecting rod 64 drives the worm shaft 63 to rotate. The rotation of the worm shaft 63 drives the worm gear 62 and the screw rod 61 to rotate, so that the screw rod 61 will enter the ground, thereby limiting the measurement frame 1. A counterweight sleeve 9 is arranged on the top of the U-shaped frame 66. A counterweight block 10 is arranged inside the counterweight sleeve 9. The bottom of the counterweight block 10 contacts the bottom of the inner wall of the counterweight sleeve 9. Through the mutual cooperation of the counterweight sleeve 9 and the counterweight block 10, when the screw rod 61 rotates, when the measurement frame 1 is too light, when the screw rod 61 contacts the ground, the measurement frame 1 will move upward. At this time, the counterweight block 10 can be placed inside the counterweight sleeve 9, thereby preventing the measurement frame 1 from moving upward when the screw rod 61 rotates. Fixed blocks 11 are fixedly installed on the front side and the rear side of the counterweight sleeve 9. The fixed blocks 11 can be inserted and installed with the U-shaped frame 66 through bolts. Through the arrangement of the fixed blocks 11, the counterweight sleeve 9 can be limited to prevent the counterweight sleeve 9 from shaking during operation.
[0033] Working principle: First, move the measuring frame 1 to the concrete to be measured. Then, the rotating block 8 can be rotated. The rotation of the rotating block 8 drives the rotation of the rotating ring 7. The rotation of the rotating ring 7 drives the rotation of the connecting rod 64. The rotation of the connecting rod 64 drives the rotation of the worm 63. The rotation of the worm 63 drives the rotation of the worm gear 62 and the screw 61. The screw 61 rotates and enters the ground, thereby limiting the measuring frame 1. Then, at this time, the measuring plate 2 drives the rotating rod 32 and the pointer 31 to rotate. At this time, the angle of the pointer 31 corresponding to the arc protractor 33 can be observed, so as to know the slump angle of the concrete.
[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
