when the floor intensity detection operation is performed, firstly, a worker places the floor to be detected on the bearing plate 5, then starts the first air cylinder 10, the first air cylinder 10 starts to drive the pressure plate to move downwards continuously, the pressure plate contacts with the floor to be detected and applies pressure to the floor to be detected along with the continuous movement of the first air cylinder 10, the floor to be detected transmits the pressure to the bearing plate 5, finally, the pressure detector 6 senses the pressure and displays the pressure data, and the worker obtains a floor pressure intensity detection result by observing the pressure detector 6, which is the floor intensity detection prior art and is not repeated herein;
although the above process completes the detection of the pressure intensity of the floor, in the detection process, the floor is not clamped, if the floor is subjected to the action of external force and moves before being pressed, the detection result of the floor intensity is easily affected, and in order to make the detection result of the floor more accurate, clamping devices 9 are fixedly arranged on two sides of the bearing plate 5;

in the detection of the strength of the floor, in order to more comprehensively reflect the strength parameters of the floor, the floor in different states of dryness and humidity needs to be detected, so that besides the conventional detection of the dry floor, the floor needs to be soaked and then detected;
however, after the floor is soaked, because the floor becomes soft, a larger pressing force is needed when the floor is detected and fixed, so that when the intensity of the floor in different states of dryness and wetness is detected, the pressing force of the detection clamp 93 needs to be changed so as to be convenient for better fixing the floor;
to achieve the above object, a part of structure is added to the pre-pressing jig 92 to realize the dry-wet state detection of the floor, thereby controlling the pressing force of the detecting jig 93, specifically:

a first spring 927 is arranged between the first sphere 926 and the inner cavity of the box body 925, when the protruding end of the first sphere 926 is acted by external force, the first sphere 926 moves upwards to retract into the box body 925, a through hole 928 is arranged on one surface of the box body 925 connected with the first pressure arm 923, and meanwhile, the inside of the first pressure arm 923 is also hollow and provided with a water inlet hole (not shown in the figure) communicated with the through hole 928;
as shown in fig. 6, in the initial state, the protruding end of the first sphere 926 is located at the outer side of the box 925, at this time, there is no gap between the first sphere 926 and the ball groove, when the first press arm 923 clamps the floor, the protruding end contacts with the bottom plate and due to the upward reaction force of the floor, the first sphere 926 is completely retracted into the box, at this time, a gap is generated between the first sphere 926 and the ball groove, and the water is suitable for flowing from the ball groove to the through hole 928 and then enters the first press arm 923 through the through hole;
in order to conveniently adjust the clamping force between the pre-pressing clamp 92 and the detection clamp 93, the second air cylinder 922 and the third air cylinder are respectively powered by two groups of pump bodies, as shown in fig. 2-4, a supporting plate 2 is fixedly arranged on one side of the detection table 4, a first air pump 7 and a second air pump 16 are respectively fixedly arranged on two sides of the supporting plate 2, wherein the output end of the first air pump 7 is communicated with a first air pipe 71, the output end of the second air pump 16 is communicated with a second air pipe 72, one end of the first air pipe 71 far away from the first air pump 7 penetrates through the bearing plate 5 and is connected with the second air cylinder 922 in the pre-pressing clamp 92 to power the second air cylinder 922, and one side of the second air pipe 72 far away from the second air pump 16 is connected with the third air cylinder in the detection clamp 93 to power the third air cylinder;
a water pump 8 for absorbing water is fixedly arranged on the supporting plate 2, the water pump 8 is positioned between the first air pump 7 and the second air pump 16, a middle rotary drum 81 is arranged on one side of the water pump 8, the middle rotary drum 81 is connected with the water pump 8 through a pipeline, the inside of the middle rotary drum 81 is hollow, and a first water pipe 82 is communicated with one side of the middle rotary drum 81;
with continued reference to fig. 4, a detecting tube 17 is connected to the first water tube 82, and an end of the detecting tube 17 away from the first water tube 82 is connected to the inner cavity of the first pressing arm 923 in the pre-pressing fixture 92, and a humidity sensor (not shown) is disposed in the detecting tube 17 for sensing the humidity in the detecting tube 17;
a PLC control system (not shown in the figure) is arranged in the base 1, and the humidity sensor, the first air pump 7, the second air pump 16 and the first air cylinder 10 are all in signal connection with the PLC control system;
to sum up:
when inspecting the floor after being soaked in water, as known from the existing floor inspection test, the soaked floor is usually soaked in water for more than twenty four hours, the surface of the soaked floor is stained with a large amount of water, and the inside of the soaked floor is also adsorbed with a large amount of water, firstly, a worker manually places the soaked floor on the inspection end face 13, then starts the first air pump 7 and the water pump 8, the first air pump 7 drives the first pressing arm 923 to press down, the first sphere 926 positioned at the bottom of the clamping end of the first pressing arm 923 is preferentially contacted with the floor, during the pressing down process, the first sphere 926 gradually moves upwards and is completely immersed into the box 925 due to the reaction force of the floor, the first spring 927 compresses, and at the moment, a gap is generated between the first sphere 926 and the sphere groove, because the water pump 8 is started to generate suction force, the suction force enables water stains on the surface of the floor to reach the through hole 928 through the ball groove, then enter the first pressure arm 923 through the through hole 928 and are transmitted into the detection tube 17 through the first pressure arm 923, after the water stains enter the detection tube 17, the humidity sensor senses the existence of water, signals are transmitted to the PLC control system, the PLC control system controls the second air pump 16 to start and simultaneously regulates the power of the first air pump 7 and the second air pump 16, so that the detection clamp 93 obtains a stronger power source and increases the clamping force of the second pressure arm, the floor is clamped tightly, and then the PLC control system controls the first air cylinder 10 to start for floor pressure intensity detection;
when detecting dry floor, the staff will wait to detect the floor and place on detecting terminal surface 13, then start first air pump 7 and water pump 8, first air pump 7 starts and drives the ejecting of second cylinder 922 output on the pre-compaction anchor clamps 92, press from both sides the floor tight through first pressure arm 923, humidity transducer can not feel the change of humidity and with signal transmission in PLC control system, PLC control system control second air pump 16 normal start, drive detection anchor clamps 93 with the floor centre gripping fixed, then PLC control system control first cylinder 10 starts, carry out pressure intensity detection to the floor.
Embodiment two: in the process of detecting the floor pressure intensity, the floors in different states are distinguished through a pre-clamping method, so that the clamping force of the clamp is adjusted, and the result of detecting the floor pressure intensity is more accurate;
however, although the method has better effect, because the water content of the immersed floor is more, a large amount of water is inevitably remained on the bearing plate 5 in the pressure detection process, the detection tube 17 only can absorb the water on the partial surface above the floor, if the water on the bearing plate 5 is not cleaned, and the residual water is easy to wet the floor to influence the detection result when the dried floor is detected later;
in the prior art, water on the bearing plate 5 is mostly removed manually, and the burden of workers is definitely increased;
in order to solve the above problem, in this embodiment, a drainage structure is added to remove the accumulated water on the carrier plate 5, specifically:
