Description

TECHNICAL FIELD

[0002] Building materials are collectively referred to as various materials widely used in building engineering, and the selection of building materials directly affects the quality, durability, safety and aesthetics of buildings. Building materials will face various friction and wear during use, and in order to ensure the quality of buildings, concrete blocks need to be subjected to wear resistance detection before use.

[0003] A building material wear resistance detection device for building engineering described in the prior art comprises a shell, a protective cover fixedly installed on the top of the shell, and side plates fixedly installed on the left and right sides of the top of the shell. The present application is provided with a moving block, a spring, a hinge rod and a grinding disc body. When the material moves upward and contacts the grinding disc body, the grinding disc body will be pushed upward, at which time the motor shell will push the two moving blocks to move in opposite directions through the two hinge rods, so that the spring is compressed, thereby enabling the spring to push the moving block inward under the action of elastic recovery, and the hinge rod pushes the motor shell downward, so that the grinding disc body can always be in contact with the outer surface of the material being detected.

The middle line of the placement plate 103 is symmetrically provided with an adjustable clamping plate 8.

The lifting plate 3 is symmetrically provided with arc-shaped through grooves 302, and a plurality of locking perforations 303 are uniformly arranged on the outer sides of the two arc-shaped through grooves 302. The upper surface of the placement plate 103 is fixedly provided with side plates 2 on both sides. The two sides of the lifting plate 3 are provided with sliding grooves matched with the side plates 2. One side of the detection shell 1 close to the human body is provided with a sealing door 101 through a hinge. The sealing door 101 is located at the placement plate 103. The bottom of the detection shell 1 is fixedly provided with support legs 102 on both sides. The sealing door 101 is made of transparent glass, which is convenient for the staff to observe the internal situation in real time.

[0033] The polishing mechanism 4 comprises a top detection assembly 5, two groups of position adjusting assemblies 6 and side detection assemblies 7. The top detection assembly 5 is installed on the lifting plate 3 through a mounting frame 304. The polishing part of the top detection assembly 5 is located below the lifting plate 3. Each group of side detection assemblies 7 is installed on the position adjusting assembly 6. Each group of position adjusting assemblies 6 is arranged at the arc-shaped through groove 302 and connected with the top detection assembly 5. The top detection assembly 5 is used for detecting the wear resistance of the top surface of the material to be detected. The position adjusting assembly 6 is used for adjusting the position of the side detection assembly 7 so as to detect the wear resistance of the side surface of the material to be detected.

[0034] The top detection assembly 5 comprises a driving motor 501. The driving motor 501 is fixed below the mounting frame 304 through screws. The mounting frame 304 is fixed on the upper surface of the lifting plate 3. The output flange of the driving motor 501 is connected with a rotating shaft 502. The bottom end of the rotating shaft 502 penetrates through the lifting plate 3 and is fixedly sleeved with a polishing disc 503. The outer wall of the rotating shaft 502 is fixedly sleeved with a driving gear 504. The driving gear 504 is located on both sides of the driving gear 504. The diameter of the driving gear 504 is greater than the diameter of the two driven gears 602. The tooth surface of the driving gear 504 is meshed and connected with the tooth surfaces of the two driven gears 602.

[0035] The guide blocks 104 are fixed on both sides of the bottom of the detection shell 1, and the upper surfaces of the two guide blocks 104 are designed as inclined surfaces. The side wall of the detection shell 1 is provided with an air suction pump 105 through screws. The suction pipe of the air suction pump 105 is connected with the space of the bottom of the detection shell 1, and the exhaust pipe of the air suction pump 105 is connected with the collection box.

[0036] In the construction engineering, when the abrasion resistance of the concrete needs to be detected, the worker opens the sealing door 101, places the concrete to be detected in the central part of the placing plate 103, and then controls the clamping plate 8 to move along the moving groove 1032 through the external control box to clamp and fix the concrete. Then, according to the detection requirements, when the top of the concrete needs to be detected, the worker starts the two hydraulic cylinders 301 through the external control box, and the telescopic ends of the two hydraulic cylinders 301 extend to push the lifting plate 3 to move downward along the two side plates 2 until the polishing disc 503 in the top detection assembly 5 contacts the top of the concrete. Then, the driving motor 501 is started, and the output end drives the rotating shaft 502 to rotate, and the rotating shaft 502 drives the polishing disc 503 to rotate to detect the abrasion resistance of the top of the concrete. At this time, the position adjusting assembly 6 is locked, so that the driving gear 504 can only drive the driven gear 602 of the position adjusting assembly 6 to rotate alone under the action of the magnetic coupler 603;

[0037] When the side wall of the concrete needs to be detected, the worker first cancels the power supply of the electromagnet 305 through the external control box, and then cancels the locking of the position adjusting assembly 6. At this time, the position adjusting assembly 6 can be controlled to move along the arc-shaped groove 302 through the top detection assembly 5, so that the side detection assembly 7 is adjusted to the specified position. Then, the electromagnet 305 is powered to re-lock the position adjusting assembly 6. Then, the side detection assembly 7 is controlled to move close to the side of the concrete until the polishing roller 703 contacts the side of the concrete. Finally, the side detection assembly 7 is started to detect the abrasion resistance of the side of the concrete.

[0038] During the detection process, the dust generated by polishing falls through the grid plate 1031 to the lower side of the placing plate 103. At the same time, the air suction pump 105 works to timely suck out the generated dust from the detection shell 1 and transport it to the collection box through the exhaust pipe, avoiding the accumulation of dust in the detection shell 1, thereby maintaining the cleanliness of the detection environment and improving the accuracy and reliability of the detection. The inclined surface design of the guide block 104 helps to guide the dust to flow smoothly to the suction pipe of the air suction pump 105, further enhancing the dust cleaning effect.

[0039] Therefore, by arranging the side detection assembly 7, the limitation that the prior art can only detect the upper surface is effectively solved, and the position adjusting assembly 6 cooperates with the arc-shaped through slot 302 and the magnetic coupler 603, so that the detection position can be flexibly adjusted to adapt to materials of different sizes, fill the gap of side wear resistance detection, and improve the versatility and flexibility of the equipment. The wear resistance of building materials in actual use can be comprehensively evaluated, and it is especially suitable for scenes where the side is easily worn in industrial plants and warehouses.

[0040] Please refer to Figure 2 、 Figure 6 and Figure 7 , one side of the two clamping plates 8 close to the material to be detected is provided with an arc groove 801, and the moving through slot 1032 is arranged on the placing plate 103 at the two clamping plates 8.

The lower surface of the placing plate 103 is centrally provided with a protective shell 805, and the second electric telescopic cylinder 804 is symmetrically installed in the protective shell 805. The telescopic end of the two second electric telescopic cylinders 804 is fixedly connected with the L-shaped push block 803 through the side wall of the protective shell 805. One side of the two clamping plates 8 close to the concrete is bonded with a rubber pad for increasing the friction of clamping and avoiding cracks in the concrete caused by excessive clamping force. The bottom end of the two moving blocks 802 is provided with an inclined surface which matches the inclined surface on the guide block 104 and can be in contact with the guide block 104 when the moving block 802 moves to the maximum stroke of the moving through slot 1032.

[0041] When the placed concrete is clamped and fixed, the two second electric telescopic cylinders 804 work, and the telescopic end will push the moving block 802 to move in the moving through slot 1032 through the L-shaped push block 803. The moving block 802 drives the clamping plate 8 to move until the clamping plate 8 is in close contact with the outer wall of the concrete, and the fixing is completed. The arc groove 801 arranged therein can adapt to the outer wall of the cylindrical concrete, and the remaining contact surface can adapt to the outer wall of the square concrete, thereby realizing clamping of concrete of various shapes.

[0045] When only the top of the concrete is detected, the electromagnet 305 is magnetized after being powered on, the electromagnet 305 with magnetism can be adsorbed with the iron sheet below through the locking through hole 303, the locking block 6063 is moved upward along the slide rod 6062, the locking block 6063 is magnetically adsorbed with the electromagnet 305 after passing through the corresponding locking through hole 303, the locking of the position adjusting assembly 6 is completed, when the driving motor 501 is started, the driving gear 504 on the rotating shaft 502 can drive the meshed driven gear 602 to rotate, so that the vertical shaft 601 rotates, the rotating force is transmitted to the magnetic coupler 603 through the two vertical shafts 601, the horizontal block 606 is locked at this time, and the driven gear 602 is separately rotated under the action of the magnetic field of the magnetic coupler 603.

[0048] The working principle of the present application is as follows:

[0049] In the construction engineering, when the wear resistance of the concrete needs to be detected, the worker opens the sealing door 101, places the concrete to be detected in the center of the placing plate 103, and then controls the two second electric telescopic cylinders 804 to work through the external control box. The telescopic ends of the two second electric telescopic cylinders 804 will push the movement block 802 to move in the moving channel 1032 through the L-shaped push block 803. The movement block 802 drives the clamping plate 8 to move until the clamping plate 8 is in close contact with the outer wall of the concrete, and the fixing is completed. Then, according to the detection requirements, when the wear resistance of the top of the concrete needs to be detected, the worker starts the two hydraulic cylinders 301 through the external control box. The telescopic ends of the two hydraulic cylinders 301 extend and push the lifting plate 3 to move downward along the two side plates 2 until the polishing disc 503 in the top detection assembly 5 contacts the top of the concrete. Then, the electromagnet 305 is powered on to generate magnetism. The electromagnet 305 with magnetism will be adsorbed to the iron sheet below through the locking perforation 303, so that the locking block 6063 moves upward along the slide rod 6062. The locking block 6063 passes through the corresponding locking perforation 303 and is magnetically adsorbed to the electromagnet 305, and the locking of the position adjusting assembly 6 is completed. At this time, the driving motor 501 is started, and the output end drives the rotating shaft 502 to rotate. The rotating shaft 502 drives the polishing disc 503 to rotate to detect the wear resistance of the top of the concrete. At the same time, the driving gear 504 on the rotating shaft 502 will drive the meshed driven gear 602 to rotate, so that the vertical shaft 601 rotates. The two vertical shafts 601 transmit the rotating force to the magnetic coupler 603. At this time, the horizontal block 606 is locked, and the driven gear 602 rotates alone under the magnetic field action of the magnetic coupler 603.

[0050] When the wear resistance of the side wall of the concrete needs to be detected, the electromagnet 305 is powered off, the magnetic attraction disappears, and the locking block 6063 moves downward along the slide rod 6062 under the action of gravity and reenters the groove 6061, canceling the locking. Then, the driving motor 501 is started. At this time, the driving gear 504 rotates, and the two meshed driven gears 602 rotate while performing circular motion along the outside of the driving gear 504. The two vertical shafts 601 rotate through the magnetic coupler 603 and drive the moving plate 604 to move. The moving plate 604 drives the movable plate 605 to move along the arc-shaped channel 302. The movable plate 605 drives the horizontal block 606 and the vertical plate 607 to move. The vertical plate 607 drives the side detection assembly 7 to move until it moves to the detection position. The electromagnet 305 is powered on again to lock the horizontal block 606 again. Then, the height of the lifting plate 3 is adjusted so that the polishing disc 503 contacts the top of the concrete. Then, the first electric telescopic cylinder 701 is started, the telescopic end of which pulls the U-shaped frame 702 to move. The U-shaped frame 702 drives the polishing roller 703 to approach the side of the concrete to be detected until it contacts. Then, the motor 705 is fixed to work and drive the polishing roller 703 to rotate. At the same time, the first electric telescopic cylinder 701 continues to contract in cooperation with the polishing roller 703 to detect the wear resistance of the side of the concrete.
