In embodiment 4, based on embodiment 1, the cantilever 15 is provided with a transverse groove, a plurality of rollers 29 are uniformly distributed in the transverse groove in the transverse direction, the axes of the rollers 29 are arranged along the front-back direction, the rollers 29 are rotatably connected with the cantilever 15, the wire 16 is slidably connected with the rollers 29 in a straight shape, the wire 16 and the rollers 29 form a fixed pulley structure, and the rollers 29 are used for converting sliding friction between the wire 16 and the cantilever 15 into rolling friction between the wire 16 and the rollers 29, so that friction resistance when the wire 16 moves is reduced.
When the device is used, the motor 32 rotates, any belt wheel 30 rotates to drive the annular belt 31 to do circular motion, and the driving gear 35 rotates through the meshing transmission of the teeth on the driving gear 35 and the teeth on the annular belt 31.
When the whole measurement of the invention is finished and needs to be reset, because the downward moving depths of the probe rods 6 are different, some first springs 8 are in a compressed state when the reset is started, some first springs 8 are in an initial state, when the detection ruler 1 is separated from the wall surface, the first springs 8 in the compressed state are reset and the probe rods 6 move downwards relative to the screw rods 2, at the moment, the motor 32 is enabled to rotate reversely, the driving gear 35 rotates reversely, the screw rods 2 move upwards to drive the probe rods 6 to move upwards, the screw rods 2 and the probe rods 6 can be seen as a rigid body at the moment, wherein the screw rods 2 with the shortest downward moving distance relative to the detection ruler 1 are firstly restored to the initial state of the invention, the wire ropes 16 corresponding to the screw rods become the initial tensed state of the invention, the lower end surfaces of the probe rods 6 on the screw rods are flush with the bottom surface of the detection ruler 1, and at the moment, other screw rods 2 are not reset yet, so the screw rods, because the screw rod 2 and the feeler lever 6 are rigidly connected into a whole in the upward moving process, the feeler lever 6 is driven to move upwards by the continuous upward moving of the screw rod 2, the upward moving of the feeler lever 6 drives the strip 11 to move upwards through the cord 16 and is transmitted through the second rack 12, the unlocking gear 13 and the first rack 10, the cam push rod 4 is separated from the spiral groove, the screw rod 2 and the feeler lever 6 fall due to self weight, the cord 16 is changed into a soft state, the cam push rod 4 moves rightwards under the action of the first pressure spring 9 and is meshed with the spiral groove again, then the process is repeated, namely, the screw rod 2 continuously rises, falls, rises and falls again, and falls again, the subsequent screw rod 2 resetting process is consistent with the screw rod 2 resetting process, when the last screw rod 2 is reset, the motor 32 is turned off, and the falling of the screw rod 2 and the resetting of the cam push rod 4 are simultaneously carried out, so that the screw, And in the falling process, when all the screws 2 are reset, the heights of the screws 2 are the same.
When the invention is used in concrete, no matter measuring wall surface or road surface, firstly pressing the bottom surface of the detection ruler 1 on the measured surface, starting the motor 32, after the motor 32 rotates for a period of time, closing the motor 32, clearly observing the depth of the concave part of the measured surface measured by each distance measuring mechanism through the observation hole 34, namely the flatness of the measured surface, after recording the measured value, taking down the detection ruler 1, reversing the motor 32, resetting the device as a whole, selecting the next test position for measurement, wherein the elasticity of the first spring 8 is far larger than that of the first compression spring 9, but still within the controllable range of human hand, namely, human hand can overcome the maximum elasticity of a plurality of first springs 8 in the device within a long time, the invention needs to tightly press the detection ruler 1 by hand during a period of time from the beginning of starting the motor 32 to the observation of the measured value, the detection ruler 1 can be separated from and contacted with the detected surface in the integral resetting stage.
