Description

Technical Field

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

[0002] Building blocks are a type of block-shaped building product that is larger than clay bricks. The raw materials for these blocks are widely available and of many varieties. They can be sourced locally and are inexpensive. At production and use sites, it is necessary to conduct sampling inspections on the same batch of building blocks to assess whether they meet the design requirements, in order to avoid safety hazards in buildings due to unqualified building block quality.

[0003] The most commonly used method for testing the strength of masonry blocks is the direct test method. The direct test method is to place the masonry block sample on the support platform of the hydraulic equipment, apply pressure through the hydraulic equipment until the masonry block is destroyed, measure the failure load, and calculate the strength of the masonry block based on this. In the process of applying pressure to the masonry block to break it, a large amount of debris will splash out. These splashes may cause harm to people's bodies, and even threaten people's lives in severe cases. After the masonry block is crushed, the fragments will remain on the support platform of the hydraulic equipment. People need to manually remove the fragments before the next round of testing can be carried out. This requires a lot of time and energy, resulting in low detection efficiency.

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0035] A building block strength testing device, see Figure 1-Figure 7, including a frame 1, a support platform 2 is connected to the lower part of the frame 1, a hydraulic cylinder 3 is installed on the upper part of the frame 1, a pressure block 4 is connected to the telescopic rod of the hydraulic cylinder 3, a control panel 5 is installed on the upper front side of the frame 1, the control panel 5 is electrically connected to the hydraulic cylinder 3, and the extension and contraction of the piston rod of the hydraulic cylinder 3 and the pressure can be controlled by the control panel 5. The left rear side and the right front side of the top of the pressure block 4 are connected to the guide rod A6, and the two guide rods A6 are slidably connected to the sliding sleeve 7 that can move up and down. The guide rod A6 is sleeved with a compression spring 8, and the compression spring 8 is connected to the sliding sleeve 7 and the guide rod A6. A protective cover 9 is connected between the two sliding sleeves 7, and the protective cover 9 covers the pressure block 4. A placement plate 10 that can be turned up and down is hinged on the top of the support platform 2, and the placement plate 10 is connected to the left and right sides of the short rod 1 1. A T-shaped plate 12 is connected to the front side of the top of the pressing block 4. Two guide rails 13 are symmetrically connected to the upper part of the T-shaped plate 12. T-shaped slide bars 14 that can move up and down are slidably connected to the two guide rails 13. Push blocks 15 that can rotate up and down are hinged at the lower parts of the rear sides of the two T-shaped slide bars 14. The two push blocks 15 are respectively aligned with the two short rods 11. The height of the push blocks 15 is lower than the height of the protective cover 9. Positioning blocks 16 are connected to the lower parts of the rear sides of the two T-shaped slide bars 14. The positioning blocks 16 are located at the lower side of the push blocks 15 and contact with the push blocks 15. The top of the positioning blocks 16 is an inclined surface, so that the push blocks 15 are in a tilted state with a high front and a low back. It should be noted that the T-shaped plate 12, the guide rails 13, the T-shaped slide bars 14, the push blocks 15 and the positioning blocks 16 constitute a pushing assembly.

[0036] The block sample is placed on the placement plate 10, and then the telescopic rod of the hydraulic cylinder 3 is controlled to extend to push the pressing block 4 downward to apply pressure to the block sample until the block is destroyed, and the failure load is measured, and the strength of the block is calculated accordingly. The pressing block 4 moves downward to drive the guide rod A6, the sliding sleeve 7, the compression spring 8 and the protective cover 9 to move downward, so that the protective cover 9 covers the block. When the protective cover 9 moves down to contact the placement plate 10, the protective cover 9 and the sliding sleeve 7 cannot move further downward, so that the pressing block 4 continues to move downward to apply pressure and drive the guide rod A6 to continue to move downward to compress the compression spring 8. Covering the block with the protective cover 9 can block the debris to prevent the debris from splashing, thereby protecting the lives of the workers. The pressing block 4 moves downward and drives the T-shaped plate 12, the guide rail 13, the T-shaped slide bar 14, the push block 15 and the positioning block 16 to move downward. When the push block 15 moves downward to contact the short rod 11, the push block 15 continues to move downward and is pushed by the short rod 11 to rotate upward. When the push block 15 moves downward to pass over the short rod 11, the push block 15 rotates downward and resets under the action of gravity. When the T-shaped slide bar 14 moves downward to contact the ground, it cannot move further downward, and the guide rail 13 continues to move downward along the T-shaped slide bar 14, so that the strength of blocks of different heights can be tested. After completing one inspection, the telescopic rod of the hydraulic cylinder 3 is controlled to shorten to pull the pressure block 4 to move up and reset. The pressure block 4 moves up and drives the guide rod A6 to move up so that the compression spring 8 returns to its original state. When the pressure block 4 moves up to contact with the sliding sleeve 7, it continues to move up and pushes the sliding sleeve 7 to move up and reset with the protective cover 9. When the pressure block 4 moves up, it drives the guide rail 13 to move up through the T-shaped plate 12. When the guide rail 13 moves up to its inner bottom and contacts the upper part of the T-shaped slide bar 14, the guide rail 13 continues to move up and drives the T-shaped slide bar 14 to drive the push block 15 and the positioning block 16 to move up. At this time, the protective cover 9 has moved up to be separated from the placement plate 10, which will not affect the subsequent upward flipping of the placement plate 10; because the positioning block 16 is located at the lower side of the push block 15 and contacts the push block 15, the push block 15 will not rotate downward after moving up to contact the short rod 11, but will push the short rod 11 to move up, so that the placement plate 10 can be flipped upward to pour out the fragments on it, so as to achieve the purpose of automatically removing the fragments after the detection is completed, so that there is no need to manually remove the fragments, thereby saving time and effort and improving the detection efficiency. When the push block 15 moves up to pass over the short rod 11, the placement plate 10 flips down and resets under the action of gravity. Since the top of the positioning block 16 is an inclined surface, the push block 15 is in a tilted state with a high front and a low back, so that the short rod 11 can be more stably and smoothly separated from the push block 15.

[0037] See also Figure 8 A fixing mechanism for fixing the building blocks is provided on the placement plate 10, and the fixing mechanism includes an inverted U-shaped plate 17 connected to the front side of the placement plate 10, and a bidirectional screw rod 18 is rotatably connected to the lower part of the inverted U-shaped plate 17. A left and right L-shaped clamping plate 19 is threadedly connected to the bidirectional screw rod 18, and the L-shaped clamping plate 19 is slidably matched with the placement plate 10 and the inverted U-shaped plate 17.

[0038] By rotating the bidirectional screw rod 18, the two L-shaped clamps 19 can be brought closer to each other to clamp and fix the building block, so as to avoid displacement of the building block when the pressure block 4 moves down to apply pressure to the building block, thereby improving the detection accuracy and enhancing the detection reliability. The reverse bidirectional screw rod 18 can make the two L-shaped clamps 19 move away from each other.

[0039] See also Figure 9-10 A reinforcement mechanism is provided at the lower part of the frame 1, and the reinforcement mechanism includes a connecting seat 20, a connecting plate 21 and an H-shaped support plate 22. The front and rear sides of the lower part of the frame 1 are symmetrically connected with connecting seats 20, and the four connecting seats 20 are hinged with connecting plates 21 that can be turned up and down, and an H-shaped support plate 22 is connected between the tops of the left and right connecting plates 21.

[0040] See also Figure 9-10 A locking mechanism for locking the connecting plate 21 is provided at the lower part of the frame 1, and the locking mechanism includes a guide rod B23 and a U-shaped pull rod 24. The lower parts of the outer walls on the left and right sides of the frame 1 are slidably connected with the U-shaped pull rod 24 through the guide rod B23. A tension spring 25 is connected between the U-shaped pull rod 24 and the guide rod B23. A card slot is provided on the sides of the left and right connecting plates 21 facing away from each other. The front and rear sides of the top of the U-shaped pull rod 24 are connected with a card block A26 engaged with the card slot on the connecting plate 21. The front and rear sides of the lower part of the U-shaped pull rod 24 are connected with a card block B27 engaged with the card slot on the connecting plate 21. The card block B27 runs through the frame 1.

[0041] Initially, the connecting plate 21 is in a vertical state, and the block A26 is stuck in the slot on the connecting plate 21 to lock the connecting plate 21. When the detection work is to be carried out, the U-shaped pull rod 24 is pulled away from the frame 1, so that the block A26 moves out of the slot on the connecting plate 21 to release the lock of the connecting plate 21, and the tension spring 25 is compressed accordingly, and then the connecting plate 21 is flipped downward to a horizontal state so that the H-shaped support plate 22 contacts the ground. After the connecting plate 21 is flipped downward to a horizontal state, the slot on it is aligned with the block B27, and the U-shaped pull rod 24 is released. Under the resetting action of the tension spring 25, the U-shaped pull rod 24 drives the block A26 and the block B27 to move and reset in the direction close to the frame 1, and the block B27 is then inserted into the slot on the connecting plate 21 to lock the connecting plate 21, thereby preventing the connecting plate 21 from swinging on its own to improve stability. The H-shaped support plate 22 is in contact with the ground, which can increase the support points of the frame 1 to increase the support area, thereby providing more supporting force to improve the stability of the frame 1 and avoid the frame 1 from tipping over during the detection work, thereby improving the safety. When the device is to be moved, the connecting plate 21 is flipped upward and reset to separate the H-shaped support plate 22 from the ground.

[0042] See also Fig.11Two torsion springs 28 are symmetrically connected to the connection between the placement plate 10 and the support 2, and two arc covers 29 are symmetrically connected to the rear side of the placement plate 10. The two arc covers 29 cover the two torsion springs 28 respectively, and two arc guide grooves cooperating with the arc covers 29 are symmetrically opened on the rear side of the support 2.

[0043] The torsion spring 28 can make the placement plate 10 fit tightly against the support 2, preventing the placement plate 10 from swinging up and down when carrying the device, thereby preventing impurities from entering between the placement plate 10 and the support 2, causing the placement plate 10 to be unable to fit tightly against the support 2, and further preventing the placement plate 10 from being squeezed and deformed during detection work. The torsion spring 28 is covered by the arc cover 29, which can prevent the fragments from falling on the torsion spring 28 when the placement plate 10 is flipped upward to pour out the fragments, thereby protecting the torsion spring 28. When the placement plate 10 is flipped upward, the arc cover 29 is driven to rotate and enter the arc guide groove on the rear side of the support 2, to ensure that the placement plate 10 can be flipped up and down stably and smoothly.

[0044] See also Fig.12 The lower parts of the inner walls on both sides of the frame 1 are connected with fixed plates 30, and the fixed plates 30 are located on the front side of the support platform 2. A rotating shaft 31 is rotatably connected between the two fixed plates 30, and two wheels 32 are symmetrically connected to the rotating shaft 31. The height of the wheels 32 is higher than the bottom of the frame 1.

[0045] Since the height of the wheel 32 is higher than the bottom of the frame 1, the wheel 32 does not contact the ground, thereby preventing the device from being displaced during the detection work. The frame 1 can be tilted forward and downward to make the wheel 32 contact the ground, and then the frame 1 can be pushed to move the frame 1, thereby facilitating the movement of the device.

[0046] See also Fig.12 An inverted U-shaped handle 33 is connected to the top of the frame 1, and an anti-skid cover is connected to the inverted U-shaped handle 33. The inverted U-shaped handle 33 can be used to facilitate pulling the frame 1 to tilt and move forward and downward, and the anti-skid cover can increase the friction with the hand to prevent slipping.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
