[0048] See also Figure 1-9 The present invention provides a technical solution: a detection device and a detection method for a polyurethane plastering board for construction, comprising a control chamber 1, a base 5, a dial indicator 4 and a moving component.

[0049] A workbench 101 is fixedly connected to the upper side of the control chamber 1, a reversing ring 2 is rotatably connected inside the workbench 101, and concave limit blocks 201 are fixedly connected to both ends of the inner side of the reversing ring 2. A pair of concave limit blocks 201 limit the trowel body 6;

[0050] The lower end of the control chamber 1 is fixedly connected to a support platform 3, the upper end of the support platform 3 is fixedly connected to a pair of special-shaped support blocks 301, the upper ends of the special-shaped support blocks 301 are rotatably connected to the reversing ring 2, and a support plate 302 is fixedly connected between the pair of special-shaped support blocks 301, the support plate 302 supports the mud trowel body 6, and the width of the support plate 302 is smaller than the width of the mud trowel body 6;

[0051] The movable assembly is arranged on the upper side of the support platform 3, and the dial indicator 4 is arranged on the upper side of the movable assembly. In the initial state, the highest point of the probe of the dial indicator 4 is higher than the upper surface of the support plate 302, and the probe of the dial indicator 4 is attached to the lower side of the long side of the trowel body 6 for detection.

[0052] The trowel board body 6 to be inspected is manually placed on the upper side of the support plate 302, and a pair of concave limit blocks 201 limit it. Since the width of the support plate 302 is smaller than the width of the trowel board body 6, the long sides of the trowel board body 6 extend outside the support plate 302, which is convenient for detection by the dial indicator 4 on the lower side. In addition, since in the initial state, the highest point of the probe of the dial indicator 4 is higher than the upper surface of the support plate 302, when the trowel board body 6 is placed on the support plate 302, the probe of the dial indicator 4 on the lower side of the long side is pressed down by the gravity of the trowel board body 6 itself, so that the probe is in a compressed rebound state, which can make the probe close to the lower side of the long side of the trowel board body 6, thereby further ensuring the accuracy of the detection data; then the dial indicator 4 is driven by the moving assembly to move in a straight line 4, and the trowel body 6 is automatically inspected.

[0053] The moving assembly includes a rack 401, a dial base is fixedly connected to the middle of the upper end of the rack 401, the upper end of the dial base is fixedly connected to the dial indicator 4, a transverse groove 303 is transversely penetrated through the upper side of the support platform 3, the rack 401 and the transverse groove 303 are slidably matched, the dial base is moved between a pair of special-shaped support blocks 301, a square groove is opened on the upper side of the support platform 3, the square groove and the transverse groove 303 are connected to each other, a spur gear 304 is rotatably connected in the square groove, and the spur gear 304 and the rack 401 are meshed with each other.

[0054] Preferably, when the dial indicator 4 needs to be driven to move linearly, the spur gear 304 is rotated to drive the rack 401 to move, and the rack 401 can drive the dial indicator base and the dial indicator 4 to move.

[0055] A pair of sinking grooves are provided on the upper side of the support plate 302 , and a top plate 102 is arranged in the sinking grooves. A spring retractable rod 1 is arranged between the top plate 102 and the sinking grooves. When the top plate 102 sinks into the sinking grooves, the upper end surface is flush with the support plate 302 .

[0056] Preferably, since in the initial state, the highest point of the probe of the dial gauge 4 is higher than the upper surface of the support plate 302, the probe is in a compressed rebound state during detection, and when it is necessary to switch the detection of the long side, the reversing ring 2 drives a pair of concave limit blocks 201 and the mud trowel body 6 to rotate 180 degrees, and the other long side that has not been detected is rotated to the upper side of the dial gauge 4. However, in this process, when the mud trowel body 6 is rotated to separate from the probe of the dial gauge 4, the probe rises and resets, and when the other long side of the mud trowel body 6 is rotated, It will interfere with the probe, and the trowel body 6 will not be able to rotate into place. Therefore, a lifting plate 102 is provided. Specifically, when the reversing ring 2 rotates, the lifting plate 102 rises synchronously to lift the trowel body 6 to be higher than the rebounding probe height. At this time, the trowel body 6 rotates and will not interfere with the probe. The undetected long side moves to the upper side of the probe, and then under the resetting action of the spring contraction rod 1, the lifting plate 102 is lowered and retracted into the trough, and the trowel body 6 can be lowered and reset, and the probe is pressed down again to start detection.

[0057] A circular through hole is provided in the middle of the upper end of the support plate 302, the circular through hole is connected to the sink, a disc 103 is rotatably connected in the circular through hole, a pair of arc blocks 104 are fixedly connected to the upper end of the disc 103, one end of the arc block 104 is provided with an oblique chamfer, and a trapezoidal notch is provided at one end of the ejection plate 102, the trapezoidal notch is adapted to the arc block 104, when the disc 103 rotates 180 degrees, the ejection plate 102 rises and resets.

[0058] Preferably, when it is necessary to drive the ejecting plate 102 to be lifted upward, the disc 103 is rotated to drive a pair of arc blocks 104 to rotate. The inclined surface of the arc block 104 is matched with the trapezoidal notch of the ejecting plate 102. The arc block 104 pushes the ejecting plate 102 along the inclined surface, thereby lifting it up, so that the ejecting plate 102 can be moved upward to lift the mud trowel body 6. After the disc 103 drives the pair of arc blocks 104 to rotate 180 degrees, the ejecting plate 102 returns to the gap between the pair of arc blocks 104 under the resetting action of the spring contraction rod 1, so that the mud trowel body 6 can be reset after changing direction.

[0059] The lower end of the disc 103 is rotatably connected to a drive shaft 105, and the drive shaft 105 is driven to rotate by a motor component, and the motor component is fixed to the lower end of the control chamber 1;

[0060] Straight key grooves are provided on both sides of the driving shaft 105, and a driving key 106 is slidably fitted in the straight key grooves. A torque ring 107 is fixedly connected to the outer side of the driving key 106. A plurality of arc-shaped slots are provided at the upper and lower ends of the torque ring 107. The torque ring 107 is movably arranged on the driving shaft 105;

[0061] The lower end of the disc 103 is fixedly connected with a pair of connecting rods 108, which are matched with the arc-shaped slot. The drive shaft 105 passes through the spur gear 304 and is clearance-matched with it. The upper end of the spur gear 304 is fixedly connected with a pair of connecting rods 109, which are matched with the arc-shaped slot.

[0062] A spring telescopic rod 402 is provided at one end of the rack 401 , and one end of the spring telescopic rod 402 is connected to the control chamber 1 .

[0063] Preferably, the drive shaft 105 is driven to rotate by the motor, and the drive shaft 105 transmits torque through the straight key slot and the drive key 106, driving the torque ring 107 to rotate. The upper and lower ends of the torque ring 107 are provided with a plurality of arc-shaped slots, which are respectively adapted to the first clamping rod 108 and the second clamping rod 109. When the torque ring 107 moves downward, the second clamping rod 109 and the arc-shaped slots are mutually clamped. At this time, the drive shaft 105 rotates, which drives the torque ring 107 and the spur gear 304 to rotate. The spur gear 304 can drive the dial indicator 4 to move linearly, thereby completing the detection of the mud trowel body 6;

[0064] When the torque ring 107 moves upward, the connecting rod 108 and the arc-shaped slot are mutually engaged, and the driving shaft 105 rotates at this time, and the disk 103 is driven to rotate through the torque ring 107, so that the ejecting plate 102 and the mud trowel body 6 can be lifted up, and the reversing ring 2 rotates to switch the side to be detected. In other words, only a single motor component is used to realize the driving of the dial indicator 4 to complete the detection work, and also realize the driving of the ejecting plate 102 to lift the mud trowel body 6, which is highly practical and saves costs.

[0065] Preferably, a spring telescopic rod 402 is provided to facilitate resetting the dial indicator 4 after the detection is completed and then detecting the other long side. Specifically, when the spur gear 304 is driven by the torque ring 107 to drive the rack 401 and the dial indicator 4 to move, the spring telescopic rod 402 is gradually compressed until the dial indicator 4 completes the detection of the long side of one side of the trowel body 6. At this time, the torque ring 107 moves upward and separates from the clamping rod 109, so that the spur gear 304 loses its restriction. At this time, under the resetting action of the spring telescopic rod 402, the rack 401 and the dial indicator 4 are pushed to reset to the origin to facilitate the next detection work.

[0066] The outer side of the torque ring 107 is rotatably connected to a driving plate 110, and the upper ends of the four sides of the driving plate 110 are provided with guide telescopic rods 111, and the upper ends of the guide telescopic rods 111 are connected to the support plate 302;

[0067] One end of the driving plate 110 is fixedly connected to the limiting rod 112 , and the lower end of the supporting plate 302 is slidably matched with the sliding plate 202 . The middle side of the sliding plate 202 is penetrated by a limiting inclined groove 203 , and the limiting rod 112 extends into the limiting inclined groove 203 .

[0068] Preferably, a driving plate 110 is provided on the outer side of the torque ring 107, and the driving plate 110 drives the torque ring 107 to move up and down, and a plurality of guide telescopic rods 111 are used for guidance. Specifically, a limiting rod 112 is provided at one end of the driving plate 110, and the limiting rod 112 extends into a limiting bevel groove 203 of a sliding plate 202 on one side. When the sliding plate 202 moves horizontally, and because the limiting rod 112 can only move up and down, the limiting bevel groove 203 drives the limiting rod 112 to move upward or downward, so that the torque ring 107 can switch the driving object.

[0069] One end of the sliding plate 202 is fixedly connected with a pair of fixing rods 204, a pair of side plates 205 are arranged on the inner side of a pair of special-shaped support blocks 301, a plurality of guiding telescopic columns are arranged between the side plates 205 and the special-shaped support blocks 301, the table seat is located between the pair of side plates 205, the fixing rod 204 is connected with one side of the side plate 205, the lower end of the support plate 302 is fixedly connected with an electromagnet block 206, the fixing rod 204 penetrates the electromagnet block 206 and is in clearance with the electromagnet block 206, and the sliding plate 202 is set to be a magnetic metal;

[0070] The other end of the sliding plate 202 is provided with a spring retracting rod 207, one end of which is connected to the side plate 205, and the lower end of the support plate 302 is fixedly connected with an electromagnet block 208, the spring retracting rod 207 penetrates the electromagnet block 208 and is in clearance with the electromagnet block 208, and a spring member is provided between the electromagnet block 208 and the sliding plate 202;

[0071] When the first electromagnet block 206 and the sliding plate 202 are mutually attracted, the torque ring 107 and the second clamping rod 109 are mutually clamped; when the second electromagnet block 208 and the sliding plate 202 are mutually attracted, the torque ring 107 and the first clamping rod 108 are mutually clamped.

[0072] Preferably, in order to further improve the stability of the torque ring 107 when driving, an electromagnet block 1 206 and an electromagnet block 208 are provided, the sliding plate 202 is restricted to move between the two, and the sliding plate 202 itself is a magnetic metal. When the sliding plate 202 and the electromagnet block 1 206 are mutually attracted, the limiting rod 112 is at the lower end of the limiting inclined groove 203, and the torque ring 107 can stably drive the spur gear 304. When the sliding plate 202 and the electromagnet block 208 are mutually attracted, the torque ring 107 can stably drive the disc 103.

[0073] A spring member is provided so that in the initial state, the sliding plate 202 and the electromagnet block 1 206 are in contact with each other and away from the electromagnet block 208, and the spring retraction rod 207 is also in the initial state (i.e., it is not compressed or stretched without external interference). At this time, the limiting rod 112 is at the lower side of the limiting inclined groove 203, so that the torque ring 107 and the clamping rod 2 109 are clamped with each other, so that the spur gear 304 can be driven, and the rack 401 drives the dial indicator 4 to move toward the other side plate 205 to detect the mud trowel body 6 until the dial indicator 4 moves to the end and pushes the side plate 205. However, at this time, the electromagnet block 1 206 and the sliding plate 202 are mutually attracted, and the sliding plate 202 cannot move. Therefore, the dial indicator 4 pushes the side plate 205, and the side plate 205 drives the spring retraction rod 207 to stretch itself, and then the electromagnet block 1 206 is powered off. Under the reset action of the spring retractable rod 207, the sliding plate 202 is pulled toward the electromagnet block 208 until the two are attracted to each other, and the torque ring 107 can be driven to move upward, and the disc 103 is driven to lift the mud trowel body 6 to facilitate its own rotation 180 degrees. At the same time, the dial indicator 4 is reset under the action of the spring telescopic rod 402, and the side plate 205 currently pushed is released and reset. When the mud trowel body 6 is reversed, the electromagnet block 208 is powered off, and under the reset action of the spring part, the sliding plate 202 is pushed back to its original position, and the torque ring 107 can be controlled to descend, and the spur gear 304 is driven again to drive the dial indicator 4 to detect the other long side of the mud trowel body 6, so as to complete the bilateral detection work. The degree of automation is high. The torque ring 107 can be automatically controlled to switch up and down only by the displacement of the dial indicator 4, and the process connection is smooth.
