Further, in this embodiment, the fixed frame 113 is also provided with a bearing 1134, a first threaded rod 1135 and a second threaded rod 1136, one end of the first threaded rod 1135 is connected with the fixed frame 113 through the bearing 1134, and the second threaded rod One end of the rod 1136 is also connected with the fixed frame 113 by the bearing 1134, the first slide block 1112 is provided with the sliding sleeve on the first threaded rod 1135, the second slide block 1122 is provided with the slide sleeve on the second threaded rod 1136, the first slide block 1112 is connected with the first sliding frame 111 , and the second sliding block 1122 is connected with the second sliding frame 112 .

The first threaded rod 1135 and the second threaded rod 1136 are all connected with the fixed frame 113 by the bearing 1134, so that the first threaded rod 1135 and the second threaded rod 1136 can rotate relative to the fixed frame 113, and are installed on the first threaded rod 1135 The first slider 1112 of the first threaded rod 1135 can slide relative to the first threaded rod 1135 while the first threaded rod 1135 is rotating. Similarly, the second slider 1122 mounted on the second threaded rod 1136 can It slides relative to the second threaded rod 1136 during the rotation. The first sliding block 1112 and the second sliding block 1122 can drive the first sliding frame 111 and the second sliding frame 112 to slide relative to the fixed frame 113 during the sliding process, and the first guiding groove 1131 and the second guiding groove 1132 can play a role The guiding function ensures that the first sliding frame 111 and the second sliding frame 112 slide along a preset sliding direction.

In order to facilitate the rotation of the first threaded rod 1135 and the second threaded rod 1136, in this embodiment, the first knob 114 is also connected to the end of the first threaded rod 1135 away from the fixed frame 113, and the second threaded rod 1136 is far away from the end of the fixed frame 113. One end is also connected with a second knob 115 . Both the first knob 114 and the second knob 115 are disc-shaped (please refer to FIG. 4 ). The disc-shaped first knob 114 and the second knob 115 are convenient for the operator to rotate, and it is convenient to adjust the distance between the first sliding frame 111 and the second sliding frame 112, so that the concrete surface flatness detector 100 can measure concrete at different distances. The surface is detected, and the detection effect is better.

In this embodiment, the fixing frame 113 is roughly rod-shaped, and an instrument panel 146 is installed on the fixing frame 113 , and the instrument panel 146 is fixed relative to the fixing frame 113 . In this embodiment, the instrument panel 146 is provided with a scale, which is convenient for measuring the deflection angle of the balance bar 140 . Meanwhile, the instrument panel 146 is fixed relative to the fixed frame 113 to provide a reference for the rotation of the balance bar 140 .

The first leg 120 and the second leg 130 are used to connect to both ends of the extension frame 110. Specifically, the first leg 120 is connected to the first sliding frame 111, the second leg 130 is connected to the second sliding frame 112, and the first leg 120 is connected to the second sliding frame 112. The contact area between the supporting leg 120 and the second supporting leg 130 and the concrete surface is small, which is conducive to detecting local levelness, and the detection result is more accurate.

The balance bar 140 is rotatably mounted on the fixed frame 113 , specifically, the balance bar 140 and the fixed frame 113 form a lever. Both ends of the balance pole 140 are also provided with counterweights 147 . The weights of the counterweights 147 at both ends of the balance bar 140 are equal. When the fixed frame 113 is horizontal, the balance bar 140 maintains balance; The shape of the counterweight 147 can be selected in many ways, for example: spherical, ellipsoid, block, plate or rod, etc. In this embodiment, the shape of the counterweight 147 is preferably spherical. By rotating and installing the balance bar 140 on the fixed frame 113, the first leg 120 and the second leg 130 at both ends of the fixed frame 113 are placed on the surface of the concrete. When the surface of the concrete is uneven, the fixed frame 113 will be deflected. When rotating, the balance bar 140 mounted on the fixed frame 113 will also be deflected.

In this embodiment, the fixed frame 113 is installed on the concrete product and the reference object. If there is a height difference between the concrete product and the reference object, the balance bar 140 will deflect relative to the fixed frame 113 under the drive of the counterweights 147 at both ends. It is judged whether the balance pole 140 is deflected, so as to judge whether there is a height difference between the concrete product and the reference object. The judgment process is simple and easy to operate, and the judgment result is obvious, which is suitable for promotion.

A pointer 145 is provided in the middle of the balance bar 140 , and the pointer 145 corresponds to the middle of the instrument panel 146 . The pointer 145 can rotate with the rotation of the balance pole 140 , and the instrument panel 146 is fixed relative to the fixed frame 113 , which provides a reference for the deviation of the pointer 145 , making the deviation of the pointer 145 more intuitive. The deviation of the pointer 145 is easier to see than the deviation of the balance pole 140, so by setting the pointer 145 and the instrument panel 146 on the balance pole 140, it is possible to observe whether the balance pole 140 is offset more quickly and directly, and then Determine whether there is a height difference between the concrete product and the reference object.

It should be understood that in other embodiments of the present utility model, the concrete surface roughness detector 100 may not include the pointer 145 and the instrument panel 146, and only by the offset of the balance bar 140, it can also be judged whether the concrete product and the reference object are There is a height difference.

It should be noted that, in this embodiment, the weights of the counterweights 147 at both ends of the balance bar 140 are equal to ensure the balance of the balance bar 140. It should be understood that the counterweights 147 at one end of the balance bar 140 can be one or more , and is connected to the end of the fixing frame 113 through an elastic cord 148 . The elastic rope 148 is a rope with certain elasticity, such as rubber bands, latex bands, etc., and the elastic rope 148 is used to connect the counterweight 147, so that the counterweight 147 is easier to move when there is a height difference between the concrete product and the reference object. Shaking occurs so it is easier to observe changes in counterweight 147 and deflection of balance bar 140 .

Preferably, in order to avoid the situation that there is a height difference between the concrete product and the reference object, the counterweight 147 and the balance bar 140 are offset and shake continuously, this embodiment further improves the concrete surface flatness detector 100, By setting stoppers 149 at both ends of the balance bar 140, the stoppers 149 are used to slow down the movement of the counterweight 147, surround the stoppers 149 on the outside of the counterweights 147, and make the stoppers 149 and the counterweights The weights 147 are arranged at intervals, and the counterweights 147 will collide with the stoppers 149 during the movement process, and the stoppers 149 provide resistance to the movement of the counterweights 147, which can effectively slow down the movement of the counterweights 147, thereby making the counterweights The weight 147 and the balance pole 140 quickly tend to a balanced state, so as to observe the deviation direction and deviation angle of the balance pole 140 .

Referring to Fig. 1 and Fig. 3, the working principle of the concrete surface flatness detector 100 is: after adjusting the distance between the first sliding frame 111 and the second sliding frame 112 of the extension frame 110 to a suitable length, the concrete surface flatness The detector 100 is installed on the concrete product and the reference object whose levelness is to be measured. At this time, the first leg 120 and the second leg 130 are respectively in contact with the concrete product and the reference object. When there is no height difference between the concrete product and the reference object , the balance bar 140 on the fixed frame 113 does not deflect, but when there is a height difference between the concrete product and the reference object, the balance bar 140 on the fixed frame 113 deflects under the gravity of the counterweight 147, through the balance Whether the rod 140 deflects can intuitively and quickly determine whether there is a height difference between the concrete products. Through the instrument panel 146 installed on the fixed frame 113 and the pointer 145 installed on the balance pole 140 , the deviation of the balance pole 140 can be judged more clearly and intuitively. The arrangement of the elastic cord 148 and the stopper 149 not only makes the counterweight 147 more sensitive to the height difference, but also restores the balance quickly, so that the deviation direction and deflection of the balance bar 140 can be observed more quickly and accurately. shift angle. The length-adjustable extension frame 110 enables the concrete surface flatness tester 100 to be adapted to measure the levelness between concrete products with different spacings, and has a wider range of applications.
