Description

Technical Field

[0001] The invention belongs to the technical field of building board detection, in particular to a building board strength detection device. Background Art

[0002] Building panels are the basic materials used in construction projects to construct structures or decorative surfaces such as walls, floor slabs, and roofs. Before leaving the factory, building panels need to be strength tested to determine whether the panels are qualified.

[0003] Patent announcement number CN216449351U discloses a strength testing device for building panels, comprising a horizontal plate, a box body mounted on the upper end of the horizontal plate, a sealed door movably connected to the front left end of the box body via a hinge, an observation window provided at the front end of the sealed door, an electric cylinder mounted on the upper end of the box body, the output end of the electric cylinder extending into the box body and connected to a detection block, a thermometer provided on the left upper end of the box body, the thermometer extending into the box body, a rectangular slot provided in the middle of the upper end of the horizontal plate, a movable device mounted on the right end of the horizontal plate, the left end of the movable device extending into the rectangular slot. This patent enables the position between the two clamps to be quickly adjusted by providing a movable device, which is simple to operate, reduces adjustment time, and improves work efficiency. The temperature inside the box body can be adjusted by a heating pipe, enabling the device to test the strength of panels at different temperatures.

[0004] However, the above technical solution still has the following deficiencies in practical application: When testing the strength of building panels, the panels are first fixed in place, then an electric cylinder drives a test block to squeeze the panels. The strength is then determined based on the degree of deformation. However, to improve the accuracy of strength testing, the panels are typically squeezed at multiple locations, creating multiple dents on the surface. When workers subsequently determine the strength of the panels by observing the number and extent of these dents, some may not be obvious enough, leading to omissions or misjudgments, which can affect the accuracy of the test results.

[0023] In this embodiment, Figure 7 、 Figure 12 、 Figure 13 As shown, a hydraulic cylinder 3 is fixedly connected to one side of the upper end face of the frame 2, and the piston end of the hydraulic cylinder 3 is fixedly connected to one side of the pressure block 32. A threaded rod 2 41 is threadedly connected to one side of the slide 1 8, and both ends of the threaded rod 2 41 are rotatably set on the base 1. A motor 7 42 is fixedly connected to one side of the upper end face of the base 1, and the output end of the motor 7 42 is fixedly connected to one end of the threaded rod 2 41. A threaded rod 3 43 is threadedly connected to the lower end of the supporting plate 45, and both ends of the threaded rod 3 43 are rotatably set on the slide 1 8. One end of the slide 1 8 is fixedly connected to the motor 8 44, and the output end of the motor 8 44 is fixedly connected to one end of the threaded rod 3 43. Two ends of the upper side of the supporting plate 45 are rotatably provided with a bidirectional threaded rod 3 46, and the two sides of the bidirectional threaded rod 3 46 are respectively threadedly connected to the positioning rods 48 on both sides. A motor 9 47 is fixedly connected to one end of the supporting plate 45, and the output end of the motor 9 47 is fixedly connected to one end of the bidirectional threaded rod 3 46.

[0024] One end of the connecting plate 39 is fixedly connected to the motor 6 34 , and the output end of the motor 6 34 is fixedly connected to one end of the sponge roller 33 .

[0025] Specifically, in existing technologies, when testing the strength of building panels, the panels are first fixed, then an electric cylinder drives a testing block to squeeze the panels, and the strength of the panels is determined based on the degree of deformation. However, to improve the accuracy of strength testing, the panels are typically squeezed at multiple locations, creating multiple pits on the surface. When workers subsequently determine the strength of the panels by observing the number and degree of the pits, some pits may not be obvious enough, leading to omissions or misjudgments, thus affecting the accuracy of the test results.

[0026] Therefore, in order to solve the above problems, when using this embodiment, the plate to be inspected is placed between the two positioning rods 48, and the two positioning rods 48 are moved closer to each other by rotating the two-way threaded rod 3 46 driven by the motor 9 47 until the two positioning rods 48 clamp the plate.

[0027] The hydraulic cylinder 3 then drives the pressing block 32 downward to squeeze the surface of the sheet. Simultaneously, the lateral position of the sheet can be adjusted by rotating the threaded rod 41 through the motor 7 42 and the threaded rod 3 43 through the motor 8 44, allowing the pressing block 32 to squeeze different locations on the sheet surface. When the squeezing operation is completed, the pressing block 32 is moved away from the sheet surface. The paint inside the paint bucket 4 is then pumped out by the pump body 36 and sprayed from the nozzle 40 onto the sponge roller 33 through the hose 37 and the hard tube 38. Simultaneously, the motor 6 34 drives the sponge roller 33 to rotate, ensuring that the paint is evenly coated on the surface of the sponge roller 33. Then, the cylinder 3 35 is used to drive the sponge roller 33 to descend so that the sponge roller 33 fits the surface of the plate. At this time, the plate is driven to move laterally so that the plate and the sponge roller 33 move relative to each other. The paint on the surface of the sponge roller 33 will be coated on the surface of the plate, and the paint will not be coated in the pits, thereby making the pits clearly distinguishable from the rest of the plate. The worker can then more intuitively observe the number and degree of the pits, avoiding omissions or misjudgments, which is conducive to improving the accuracy of the detection results.

[0035] Specifically, in the above embodiment, although pigment can be applied to the surface of the plate to facilitate worker observation of pits, in some cases, the number of plates to be tested is large, and to improve testing efficiency, the pressed plates need to be placed together first and then observed collectively. To facilitate placement and save space, the plates are usually stacked. When stacked, friction between the plates occurs, which can easily wear off the pigment applied to the plate surface, thereby affecting the subsequent observation of pits on the plate surface.

[0036] Therefore, to solve the above problem, in this embodiment, when in use, the film 21 is unwound by rotating the reel 10 via motor 19, so that the end of the film 21 is pressed by the pressure roller 17. After the surface of the plate is coated with paint, the slider 5 is driven to slide laterally on the frame 2 by rotating the threaded rod 11 via motor 26, until the clamping ends of the two finger cylinders 60 at the lower end of the rack rod 6 align with the two corners of the film 21. The finger cylinders 60 then clamp the film 21, and the film 21 continues to unwind. The finger cylinders 60 pull the film 21 to move, unwinding the film 21 to a length sufficient to cover the plate, and then the film 21 stops unwinding. The motor 2 14 is used to drive the bidirectional threaded rod 15 to rotate, so that the two slot plates 2 13 are close to each other, and the clamping end of the finger cylinder 60 on the slot plate 2 13 is aligned with the edge of the film 21, and then the film 21 is clamped. At this time, the unrolled film 21 is supported by the four finger cylinders 60, and then the cylinder 12 is used to drive the blade 18 to descend, and the film 21 is cut with the cooperation of the cutting plate 19. At this time, the four blades 2 69 are respectively at the four corners of the film 21 to be cut, and then the cylinder 6 64 is used to drive the guide block 65 to descend, so that the blade 2 69 cuts the film 21. At the same time, the motor 12 66 drives the gear 2 67 to rotate, so that the rack rod 2 68 and the blade 2 69 move horizontally to expand the length of the incision. Then, under the action of the cylinder 6 64, the blade 2 69 is moved out of the incision until the tip of the blade 2 69 is higher than the lower end of the expansion block 57. Moreover, the cross section of the expansion block 57 is semicircular. In the initial state, the two expansion blocks 57 are attached to each other, and the two expansion blocks 57 together form a cylinder. Then, under the action of the cylinder 5 61 Drive the two expansion blocks 57 down so that the expansion blocks 57 extend into the incision, and then drive the two expansion blocks 57 away from each other by driving the two-way threaded rod 25 to rotate by motor three 22, so that the incision can be expanded. At this time, adjust the position of the finger cylinder 60 by means of cylinder two 27 and driving the two-way threaded rod one 15 to rotate, so that the position of the four corners of the film 21 changes, so that the expanded incision is aligned with the four corners of the plate, and then drive the finger cylinder 60 down under the action of the motor five 30 driving the gear one 29 to rotate and the motor eleven 58 driving the threaded rod five 59 to rotate, so that the incision of the film 21 can be accurately set at the four corners of the plate. Although the film 21 has been put on the four corners of the plate at this time, the cuts of the film 21 are only at the edges of the four corners of the plate and are easy to fall off. Therefore, after the finger cylinder 60 loosens the film 21, the motor 10 49 drives the threaded rod 4 50 to rotate, so that the two pulling rods 53 move horizontally to the top of the film 21 and fit with the surface of the film 21 under the action of the cylinder 4 51. Then the electric push rod 54 drives the transmission block 55 to move horizontally, and the two pulling rods 53 are driven by the connecting rod 56 to approach each other, so that the two sides of the film 21 are tightened toward the middle, and the cut of the film 21 will also move away from the angle of the plate, so that the cut is also tightened and not easy to fall off. At this time, the plate can be removed.The above operation is then repeated, so that the surface of each plate that has undergone extrusion testing is covered with film 21. When the plates are stacked, the paint will not be worn away due to friction between the plates, ensuring the smooth progress of subsequent observation of pits on the plate surface. In addition, when the film 21 is covered on the plate, it is placed on the plate by cutting notches at the four corners of the film 21. This makes the film 21 less likely to fall off during transportation. Moreover, after the film 21 is placed on the plate, the notches are tightened by the action of the reinforcement component, further ensuring the stability of the film 21 on the plate.

[0037] Working Principle: The sheet to be inspected is placed between two positioning rods 48. Motor 9 47 drives bidirectional threaded rod 3 46 to rotate, bringing the two positioning rods 48 closer together until they clamp the sheet. Hydraulic cylinder 3 then drives pressure block 32 downward to apply pressure to the sheet surface. Simultaneously, motor 7 42 drives threaded rod 2 41, and motor 8 44 drives threaded rod 3 43 to adjust the sheet's lateral position, allowing pressure block 32 to apply pressure to different locations on the sheet surface. Once the compression is complete, pressure block 32 is moved away from the sheet surface. Pump 36 then draws the paint from paint bucket 4, passing through hose 37 and tube 38 and spraying it from nozzle 40 onto sponge roller 33. Meanwhile, motor 6 34 drives sponge roller 33 to rotate, ensuring a uniform coating of the paint on its surface. Then, cylinder 3 35 is used to drive the sponge roller 33 downward, so that the sponge roller 33 contacts the surface of the plate. At this time, the plate is driven to move laterally, causing the plate and sponge roller 33 to move relative to each other. The paint on the surface of the sponge roller 33 is applied to the surface of the plate, and the paint is not applied to the pits, thereby clearly distinguishing the pits from the rest of the plate. This allows workers to more intuitively observe the number and degree of pits, avoiding omissions or misjudgments, which helps improve the accuracy of the inspection results. The film 21 is unwound by the motor 9 driving the reel 10 to rotate, so that the end of the film 21 is pressed by the pressure roller 17. After the plate surface is coated with paint, motor 4 26 drives threaded rod 11 to rotate, causing slider 5 to slide horizontally on frame 2 until the clamping ends of the two finger cylinders 60 at the lower end of rack rod 1 6 align with the two corners of film 21. Finger cylinders 60 then clamp film 21, and film 21 continues to unwind. Finger cylinders 60 pull film 21 to move, unwinding film 21 to a length sufficient to cover the plate. Film 21 then stops unwinding. Motor 2 14 drives bidirectional threaded rod 1 15 to rotate, bringing the two slot plates 2 13 closer together. The clamping ends of the finger cylinders 60 on slot plate 2 13 align with the edges of film 21, and then clamp film 21. At this point, the unwound film 21 is supported by the four finger cylinders 60. Cylinder 1 12 then drives blade 18 downward, and with the cooperation of cutting plate 19, the film 21 is cut.At this time, the four blades 2 69 are respectively at the four corners of the film 21 to be cut, and then the cylinder 6 64 is used to drive the guide block 65 to descend, so that the blade 2 69 cuts the film 21. At the same time, the motor 12 66 drives the gear 2 67 to rotate, so that the rack rod 2 68 and the blade 2 69 move horizontally to expand the length of the incision. Then, under the action of the cylinder 6 64, the blade 2 69 is moved out of the incision until the tip of the blade 2 69 is higher than the lower end of the expansion block 57. Moreover, the cross section of the expansion block 57 is semicircular. In the initial state, the two expansion blocks 57 are attached to each other, and the two expansion blocks 57 together form a cylinder. Then, under the action of the cylinder 5 61 Drive the two expansion blocks 57 down so that the expansion blocks 57 extend into the incision, and then drive the two expansion blocks 57 away from each other by driving the two-way threaded rod 25 to rotate by motor three 22, so that the incision can be expanded. At this time, adjust the position of the finger cylinder 60 by means of cylinder two 27 and driving the two-way threaded rod one 15 to rotate, so that the position of the four corners of the film 21 changes, so that the expanded incision is aligned with the four corners of the plate, and then drive the finger cylinder 60 down under the action of the motor five 30 driving the gear one 29 to rotate and the motor eleven 58 driving the threaded rod five 59 to rotate, so that the incision of the film 21 can be accurately set at the four corners of the plate. Although the film 21 has been placed on the four corners of the plate, the cuts of the film 21 are only at the edges of the four corners and are easy to fall off. Therefore, after the finger cylinder 60 releases the film 21, the motor 10 49 drives the threaded rod 4 50 to rotate, causing the two pull rods 53 to move horizontally above the film 21. Under the action of the cylinder 4 51, the electric push rod 54 drives the transmission block 55 to move horizontally. Under the drive of the connecting rod 56, the two pull rods 53 are moved closer to each other, causing the two sides of the film 21 to tighten toward the middle. The cuts of the film 21 will also move away from the angle of the plate, thereby tightening the cuts and making it difficult to fall off. At this time, the plate can be removed. The above operation is then repeated, so that the surface of each plate that has undergone the extrusion test is covered with the film 21. When the plates are stacked, the paint will not be worn off due to friction between the plates, ensuring the smooth progress of the subsequent observation of the pits on the plate surface. In addition, when the film 21 is covered on the plate, it is put on the plate by cutting out incisions at the four corners of the film 21. The film 21 is not easy to fall off during transportation. Moreover, after the film 21 is put on the plate, the incision will be tightened under the action of the reinforcement component, further ensuring the stability of the film 21 on the plate.
