Description

Technical Field

[0001] The present application relates to the technical field of material detection, and in particular to a cement strength detection device. Background Art

[0002] As an indispensable basic material in the construction industry, cement's strength performance is directly related to the structural safety and durability of buildings. Therefore, accurate testing of cement strength is an important part of ensuring project quality and construction safety. Generally, cement is mixed according to the proportion, and after the cement solidifies into a brick state, the cement brick is placed on the pressure sensor, and the brick is squeezed by the hydraulic rod. The strength of the cement brick is judged according to the display of the pressure sensor. However, the traditional cement strength testing method has many shortcomings, which to a certain extent limits the further development of cement strength testing technology.

[0003] The existing technology still has the following problems:

[0004] 1. Traditional testing devices mostly use single-point downward pressure. Due to the unevenness of cement block production, the contact between the single-point downward pressure cement block and the pressure block is not uniform, which easily leads to uneven pressure. If the pressure is not applied evenly, the pressure on each part of the test block will be different, causing some areas to be damaged in advance, while other areas may not have reached their ultimate strength. This will make the test results unable to truly reflect the overall strength performance of cement, thus affecting the accurate assessment of cement quality. In addition, it is difficult to detect whether the equipment is tilted during long-term use. The tilt of the equipment will also lead to uneven force, and may also cause uneven force on its transmission parts, accelerating wear and damage.

[0005] 2. When traditional testing devices conduct strength testing on cement bricks, in order to prevent the cement bricks from being crushed and splashing out fragments, baffles are generally used to surround the cement bricks for protection. When the baffles block the splashing fragments, rebound may occur, and the rebounded fragments may easily damage the equipment or bring safety hazards to the surrounding operators. In addition, the debris on the table is difficult to clean in time, and it is necessary to clean it after each cement brick is tested, which leads to a decrease in detection efficiency. Summary of the invention

[0006] In order to overcome the problem that traditional detection devices mostly adopt single-point downward pressure, the contact between the cement block and the pressure block is not uniform, which easily leads to uneven pressure.

[0017] The technical solution provided by this application has at least the following technical effects or advantages:

[0018] 1. The use of the detection component effectively solves the problem that the traditional detection devices mostly use single-point downward pressure. Due to the unevenness in the production process of cement blocks, the contact between the single-point downward pressure cement block and the pressure block is not uniform, which easily leads to uneven pressure. If the pressure is not applied evenly, the pressure on each part of the test block will be different, resulting in some areas being damaged in advance, while other areas may not have reached their ultimate strength. This will make the test results unable to truly reflect the overall strength performance of cement, thereby affecting the accurate assessment of cement quality. In addition, it is difficult to find out whether the equipment is tilted under long-term use. The tilt of the equipment will also lead to uneven force, and may also cause uneven force on its transmission parts, accelerating wear and damage. The present invention can detect whether the equipment as a whole is tilted through the detection component, ensuring that the equipment can apply uniform force during detection. At the same time, the use of multi-point uniform downward pressure can more accurately understand the strength of the entire cement concrete structure, and can provide more comprehensive strength control. This can ensure that the test data is more comprehensive and accurate, can truly reflect the overall strength level of cement concrete, and can also find possible weak strength areas in the structure, providing a basis for subsequent engineering quality control and maintenance reinforcement.

[0019] 2. The use of a protective component effectively solves the problem that when traditional testing devices perform strength testing on cement bricks, in order to prevent the cement bricks from being crushed and splashing out fragments, baffles are generally used to surround the cement bricks for protection. When the baffles block the splashing fragments, rebound may occur, and the rebounding fragments may easily damage the equipment or bring safety hazards to the surrounding operators. In addition, the debris on the table is difficult to clean in time, and it is necessary to clean it after each cement brick is tested, which leads to a decrease in detection efficiency. The present invention can flexibly block the splashing fragments through the protective component, reduce the strength of the splashing and rebounding of the fragments, thereby achieving a protective effect on the equipment and surrounding operators. At the same time, after the cement bricks are broken, vibrations can be generated to make the fragments fall from the table, and the fan wind force can quickly clean the debris and dust on the supporting table, so that the next test can be carried out quickly, thereby improving the detection efficiency.

DETAILED DESCRIPTION

[0035] When the cement block and the pressure block are pressed down at a single point, the contact is not uniform, which easily leads to uneven pressure. The present invention can detect whether the equipment as a whole is tilted through the detection component, so as to ensure that the equipment can apply uniform force during detection. At the same time, the uniform downward pressure at multiple points can more accurately understand the strength of the entire cement concrete structure and provide more comprehensive strength control. When the cement bricks are broken and splashed out, the present invention can flexibly block the splashed fragments through the protection component, reduce the rebound force of the splashing fragments, thereby achieving a protective effect for the equipment and surrounding operators. At the same time, after the cement bricks are broken, vibrations can be generated to make the fragments fall from the table top, and the wind force of the fan can be used to quickly clean up the debris and dust on the supporting table top.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] See also Figure 1As shown, a cement strength detection device comprises a compression machine body 1, support rods 2 are fixedly installed at the four corners of the upper surface of the compression machine body 1, and a fixing plate 3 is fixedly installed at the top of the support rod 2. The compression machine body 1, the support rod 2 and the fixing plate 3 form an integral body to ensure the stability of the detection component 5, and a dust box 4 is arranged on the side of the compression machine body 1. The dust box 4 is used to prevent cement fragments from leaking and falling from the protective component 6 into the inner cavity of the compression machine body 1, and the bottom end of the inner cavity of the compression machine body 1 can be tilted to facilitate the fragments to pass to the dust box 4, and can be taken out in the dust box 4, and the fragments of the inner cavity of the compression machine body 1 can be taken out regularly from the dust box 4, and the fixing plate 3 is provided with a detection component 5 on the bottom wall, and a protection component 6 is provided in the middle part of the compression machine body 1. The cement bricks to be tested are placed on the protection component 6, and the detection component 5 is used to press down to detect the strength of the cement bricks. The detection component 5 can ensure that the whole equipment remains horizontal when pressing down, provide a stable downward force, and have uniform pressure on the cement bricks. The protection component 6 can protect the splashing bricks, reduce the intensity of the splashing bricks, protect the equipment and staff, and at the same time, send out an alarm when the splashing intensity is large, so as to remind the staff to perform maintenance. In addition, the table of crushed bricks can be cleaned to ensure that the next brick can be tested for strength immediately.

[0038] See also Figure 1 and Figure 2As shown, the detection component 5 includes a hydraulic cylinder 51, which is fixedly connected to the lower surface of the fixed plate 3, and the inner cavity of the hydraulic cylinder 51 is slidably connected with a hydraulic rod 52, and the bottom end of the hydraulic rod 52 is fixedly connected with a pressure plate 53, and the lower surface of the pressure plate 53 is fixedly connected with a uniform force detection mechanism 54, and the lower surface of the fixed plate 3 is fixedly installed with a fixed plate 55, and the fixed plate 55 is used to connect the fixed plate 3 and the fixed rod 56, and the lower surface of the fixed plate 55 is fixedly installed with a fixed rod 56, and the inner cavity of the fixed rod 56 is slidably connected with a first sliding rod 57, and the bottom end of the first sliding rod 57 is fixedly connected to the pressure plate 53, and the outer surface of the fixed rod 56 is provided with a horizontal detection mechanism 58, and the horizontal detection mechanism 58 is located above the pressure plate 53, and the pressure plate 53 is located directly above the protective component 6. When the strength of the cement brick is tested, the operation of the hydraulic cylinder 51 drives the hydraulic rod 52 to move in the liquid The inner cavity of the pressure cylinder 51 moves, and the movement of the hydraulic cylinder 51 drives the pressure plate 53 to move. The movement of the pressure plate 53 drives the uniform force detection mechanism 54 to move. The movement of the uniform force detection mechanism 54 drives the first slide bar 57 to slide in the inner cavity of the fixed rod 56. The first slide bar 57 slides in the inner cavity of the fixed rod 56. In order to limit the pressure plate 53 and the uniform force detection mechanism 54, the uniform force detection mechanism 54 adopts multi-point uniform downward pressure. Even if the outer surface of the cement brick is not flat when the cement brick is formed, the cement brick can be relatively uniformly stressed, and the strength of the entire cement concrete structure can be more accurately understood, providing a more comprehensive strength test. At the same time, the horizontal detection mechanism 58 can be used to detect whether the equipment is vertical, that is, whether the pressure plate 53 and the uniform force detection mechanism 54 maintain vertical pressure on the cement brick when pressing down. When the equipment is tilted, it can be discovered in time to avoid numerical errors in cement strength testing.

[0039] See also Figure 2 and Figure 3As shown, the uniform force detection mechanism 54 includes a pressure plate 541, and both ends of the pressure plate 541 are fixedly installed with a fixing seat 542, and the inner cavity of the fixing seat 542 is rotatably connected to a first connecting strip 543. A storage block 544 is fixedly installed on the lower surface of the pressure plate 541, and there are two storage blocks 544. The inner cavity of the storage block 544 is slidably connected to a first slide seat 545, and the inner cavity of the first slide seat 545 is rotatably connected to a second connecting strip 546. One end of the second connecting strip 546 is rotatably connected to a connecting seat 547. The first connecting strip 543 is away from the fixing seat 542. One end is rotatably connected to the connection seat 547, and the outer surface of the connection seat 547 is fixedly connected to a pressure block 548. There are three connection seats 547 and pressure blocks 548. The inner cavity of the middle connection seat 547 is rotatably connected to the second connection strip 546, and the inner cavity of the connection seats 547 on both sides is rotatably connected to the first connection strip 543 and the second connection strip 546. The middle part of the pressure plate 541 is fixedly connected to the lower surface of the pressure plate 53. Due to the flatness of the outer surface of the cement brick during the manufacturing process, there will be a certain error, resulting in pressure detection when a single When the larger pressure block 548 is squeezed, it is difficult to ensure that the entire lower surface is in contact with the cement brick, resulting in uneven force. When the present application performs strength testing, the hydraulic rod 52 drives the pressure plate 541 to press down, so that the three pressure blocks 548 are in contact with the cement brick. When the cement brick is uneven, the three pressure blocks 548 will have amplitudes, so that the pressure blocks 548 can all fit tightly to the outer surface of the cement brick. At this time, the first connecting strip 543 and the second connecting strip 546 rotate in the inner cavity of the connecting seat 547, driving the first connecting strip 543 to rotate in the solid The first slide 545 slides in the inner cavity of the storage block 544, so that during the strength test, the movement of the first slide 545 can make the pressure block 548 squeeze the cement bricks, and press down at three points. Compared with the single-point strength test, the strength of the entire cement brick structure can be more accurately understood, which can ensure that the test data is more comprehensive and accurate, can truly reflect the overall strength level of cement, and can also find possible weak strength areas in the structure, providing a basis for subsequent engineering quality control and maintenance and reinforcement.

[0040] See also Figure 1 , Figure 4 and Figure 5As shown, the horizontal detection mechanism 58 includes a detection frame 581, a vertical line 582 is suspended on the outer surface of the detection frame 581, a detection seat 583 is fixedly installed on the lower surface of the detection frame 581, a second slide 584 is slidably connected to the inner cavity of the detection seat 583, a first spring 585 is sleeved on the upper end of the second slide 584, a pressure ring 586 is rotatably connected to the inner cavity of the lower end of the second slide 584, a rotating rod 587 is rotatably connected to the inner cavity of the detection seat 583, a floating block 588 is fixedly connected to the outer surface of the rotating rod 587, and a balance bar 58 is fixedly connected to the lower end of the floating block 588 9. A pointer 5810 is fixedly mounted on the outer surface of the rotating rod 587. The first spring 585 is located between the second slide 584 and the detection frame 581. The detection frame 581 and the fixed rod 56 are fixedly sleeved. The pointer 5810 and the vertical line 582 are on a straight line. The floating block 588 is symmetrically distributed about the middle part of the balance bar 589, and the pressure ring 586 and the middle part of the floating block 588 are in close contact. The balance bar 589 is located above the pressure plate 53. When the pressure plate 53 is stored, the upper surface of the pressure plate 53 and the lower surface of the balance bar 589 are in contact, so that when the pressure plate 53 is tilted, it can The balance bar 589 is driven to deflect. When the horizontal detection of the equipment is performed, the vertical line 582 can be composed of a thin rope and a weight block, so that the vertical line 582 can be vertically downward as a whole. When the equipment is tilted, the coincidence degree of the pointer 5810 and the vertical line 582 changes, that is, the pointer 5810 cannot be in a straight line with the vertical line 582. When the pressure plate 53 is tilted, the upper surface of the pressure plate 53 contacts the balance bar 589 when it is stored. The tilt of the pressure plate 53 drives the balance bar 589 to tilt, and the tilt of the balance bar 589 drives the rotating rod 587 to rotate on the detection seat 58 3, the rotation of the rotating rod 587 drives the floating block 588 to rotate, and the rotation of the floating block 588 drives the pressure ring 586 to squeeze the second slide 584, so that the second slide 584 slides in the inner cavity of the detection seat 583, and the second slide 584 squeezes the first spring 585 to deflect the angle of the pointer 5810, so that the pointer 5810 and the vertical line 582 on the detection frame 581 are not on the same straight line, so that when the equipment is tilted, it is discovered in time, which is convenient for subsequent maintenance, and at the same time, it is avoided that the force is uneven during cement strength testing, and the accuracy of the test data is improved.

There is a gap between the alarm block 641 and the adjustment block 624, the connecting plate 623 is located above the alarm block 641, and the adjustment block 624 is located between the two first buttons 645. After the cement brick is broken and splashed, the splashed fragments contact and collide with the protective cover 63, and the protective cover 63 will drive the connecting plate 623 to move, and the movement of the connecting plate 623 drives the adjustment block 624 to move, and the movement of the adjustment block 624 drives the gasket 628 to squeeze the second spring 622. At this time, the buffer rod 621 slides in the inner cavity of the buffer groove 625, so that the protective cover 63 has a flexible buffering effect as a whole, reducing the buffering force of the splashing fragments on the protective cover 63. The fixing bolt 626 can be adjusted to disengage the fixing bolt 626 and the socket 627, and the adjusting block 624 can be adjusted to the connecting bolt 626. The position of the connecting plate 623 is convenient for adjusting the initial squeezing force of the gasket 628 on the second spring 622, and for adjusting the buffering force of the protective cover 63, so as to ensure that the protective cover 63 has a flexible buffering effect and prevent splashing debris from damaging equipment and staff. When the protective cover 63 shakes to a large extent, the adjusting block 624 will contact the first button 645 and squeeze the first button 645. At this time, the pressing of the first button 645 controls the alarm 643 to issue an instant alarm, reminding the staff to perform maintenance. The moving block 644 can be driven to move on the alarm block 641 by rotating the first threaded rod 642, so that the distance between the first button 645 and the adjusting block 624 can be adjusted, so as to prevent the alarm from being issued within the controlled shaking range, and issue an alarm if the shaking range is large.This enables the equipment to be repaired in time and prolongs its service life.

When the uniform force detection mechanism 54 is pressed down, the support plate 651 moves downward. At this time, the first connecting rod 652 is stored in the inner cavity of the fixing frame 61. When pressed down, the first connecting rod 652 and the fixing frame 61 are in close contact. Under the clamping of the clamping block 658, the cement bricks always maintain a certain stability. At this time, the floating ring 654 squeezes the third spring 655 to make the second connecting rod 653 contact the inner wall of the anti-pressure machine body 1. When the second connecting rod 653 contacts the inner wall of the anti-pressure machine body 1, the support plate 651 does not move downward.

The pressure bar 668 moves in the inner cavity of the dust removal frame 661 and contacts the inner wall of the dust removal frame 661. At this time, the pressure bar 668 squeezes the fifth spring 6611 to make the third sliding bar 669 slide in the inner cavity of the fixed block 6610, so that the pressure bar 668 can move in the inner cavity of the dust removal frame 661, so that the pressure bar 668 can contact and squeeze the second button 664, so that when the support plate 651 rises, there are the wind force of the fan 667, the thrust of the clamping block 658 and the shaking effect of the support plate 651 itself.At the same time, the hollow structure and rounded corner design of the support plate 651 assist the falling of the debris, so that the debris on the support plate 651 can be removed cleanly, improving the efficiency of cement strength testing, while preventing the debris from adhering to the support plate 651 and affecting the testing effect.

[0045] In summary, the cement bricks to be tested are placed on the protective component 6, and the detection component 5 is used to press down to detect the strength of the cement bricks. The detection component 5 can ensure that the entire device remains horizontal when pressing down, provide a stable downward force, and exert uniform pressure on the cement bricks. The protective component 6 can protect the splashing bricks, reduce the force of the splashing bricks, protect the equipment and the staff, and at the same time, send out an alarm when the splashing force is large, so as to remind the staff to perform maintenance. In addition, the crushed bricks can be cleaned on the countertop to ensure The next brick can be tested for strength immediately. When testing the strength of cement bricks, the operation of the hydraulic cylinder 51 drives the hydraulic rod 52 to move in the inner cavity of the hydraulic cylinder 51. The movement of the hydraulic cylinder 51 drives the pressure plate 53 to move. The movement of the pressure plate 53 drives the uniform force detection mechanism 54 to move. The movement of the uniform force detection mechanism 54 drives the first slide bar 57 to slide in the inner cavity of the fixed rod 56. The first slide bar 57 slides in the inner cavity of the fixed rod 56. In order to limit the pressure plate 53 and the uniform force detection mechanism 54, the uniform force detection mechanism 54 adopts multi-point uniform downward pressure. When the outer surface of the cement brick is not flat when it is formed, the cement brick can be relatively evenly stressed, so that the strength of the entire cement concrete structure can be understood more accurately, and a more comprehensive strength test can be provided. At the same time, the horizontal detection mechanism 58 can be used to detect whether the equipment is vertical, that is, whether the pressure plate 53 and the uniform force detection mechanism 54 keep pressing vertically against the cement brick when pressing down. When the equipment is tilted, it can be discovered in time to avoid numerical errors in cement strength testing. The cement brick is fixed by the clamping mechanism 65, and the protective cover 63 is used to block the splashing fragments to slow down the The impact mechanism 62 has a buffering effect, reducing the rebound effect of flying bricks. The alarm mechanism 64 is used to sound an alarm when the protective cover 63 shakes greatly, and is used to maintain the equipment when the protective cover 63 shakes greatly. The dust removal mechanism 66 is used to remove dust from the bricks on the clamping mechanism 65 after they are broken. At the same time, the clamping mechanism 65 itself shakes, and the debris on the clamping mechanism 65 is shaken and squeezed off. The dust removal mechanism 66 cooperates to clean up the debris on the clamping mechanism 65, so that the next cement brick can be quickly tested for strength.
