Description

Technical Field

[0001] The present invention relates to the technical field of building engineering quality inspection, and specifically relates to a crushing device for building engineering quality inspection. Background Art

[0002] Building engineering refers to the planning, surveying, design, construction, completion and other technical work for the new construction, renovation or expansion of buildings and ancillary structures and facilities, as well as the completed engineering entities and their supporting pipelines and equipment installations. It also refers to the construction projects of various houses and buildings, also known as building work volume. This part of the investment must start construction and use materials, and can only be realized through construction activities.

[0003] During the construction of building engineering, it is necessary to conduct quality inspection on the compressive capacity of concrete. However, when traditional inspection devices are used for inspection, generally, pressure is applied to the sample and then the pressure value is obtained. However, this makes it necessary to obtain the result by reading the measurement table during inspection. If multiple samples of the same type of concrete are inspected, multiple readings are still required, which is very likely to cause reading errors, and the inspection efficiency is relatively low. It is not suitable for repeated and large-scale inspection work on the compressive capacity of building materials samples such as concrete. Summary of the Invention

[0043] In Embodiment 1: The crushing and bearing mechanism includes a first downward pressing block 501, a spherical pressing head 502, a first pressure receiving platform 503, and a spherical pressure receiving groove 504. The first downward pressing block 501 is threadedly connected to the inside of the second threaded installation port 202. The spherical pressing head 502 is integrally provided at the bottom of the first downward pressing block 501. The first pressure receiving platform 503 is threadedly connected to the inside of the first threaded installation port 104. The spherical pressure receiving groove 504 is opened on the upper surface of the first pressure receiving platform 503, so as to ensure that the sample debris can be more easily cleaned.

[0044] In Embodiment 2: The crushing and bearing mechanism includes a second downward pressing block 505, a cylindrical pressing head 506, a second pressure receiving platform 507, and a cylindrical pressure receiving groove 508. The second downward pressing block 505 is threadedly connected to the inside of the second threaded installation port 202. The cylindrical pressing head 506 is integrally provided at the bottom of the first downward pressing block 501. The second pressure receiving platform 507 is threadedly connected to the inside of the first threaded installation port 104. The cylindrical pressure receiving groove 508 is opened on the upper surface of the first pressure receiving platform 503, so as to ensure that the pressure received by the sample is more uniform.

[0045] Working principle: Since the force is mutual, the pressure applied by the connecting guide column 301 to the pressure measuring spring 312 is equal to the reverse elastic force of the pressure measuring spring 312 on the connecting guide column 301. This pressure is transmitted through the pressure measuring spring 312, the threaded push cylinder 307, the lifting push cylinder 310, the floating connecting seat 201, and the first pressing block 501 or the second pressing block 505, so that this pressure becomes the pressure applied to the sample. When the pressure measuring spring 312 undergoes elastic deformation, the elastic force of the pressure measuring spring 312 is proportional to the elongation of the pressure measuring spring 312. Therefore, by controlling the compression length of the extruded pressure measuring spring 312, the pressure on the pressure measuring spring 312, that is, the pressure applied to the sample, can be controlled.

[0046] Since the elastic force of the pressure measuring spring 312 contracted from the lower surface of the extrusion block 401 to the upper surface of the stop block 406 and the elastic force of the fitting spring 405 contracted from the lower surface of the extrusion block 401 to the upper surface of the stop block 406 are both fixed values, and since the rotation angle of the adjusting wheel 308 is proportional to the lifting length of the lifting push cylinder 310, this fixed value is directly used as the initial scale of the scale ring 306, and the subsequent elongation of the pressure measuring spring 312 is directly represented by the increase in the angle between the scale reference line 309 and the initial scale. Therefore, when the adjusting wheel 308 is turned, the scale reference line 309 can be compared with the scale on the scale ring 306 to ensure that the set pressure value can be directly read on the surface of the adjusting wheel 308;

[0047] Therefore, when in use, first turn the adjustment wheel 308 to adjust the spring strength. When turning the adjustment wheel 308, the adjustment wheel 308 pushes the lifting push cylinder 310 to extend or retract inside the guide cylinder 303 through the thread, thereby squeezing the pressure measuring spring 312 to contract or extend, thereby adjusting the extension length of the pressure measuring spring 312. When turning the adjustment wheel 308, the pressure value is set by comparing the scale reference line 309 with the scale on the scale ring 306, that is, the pressure that the sample is subsequently subjected to. When setting, this pressure value is set to be slightly larger than the qualified pressure of this sample;

[0048] Then, the floating connection seat 201 is lifted upwards, and the sample is placed inside the spherical pressure groove 504 or the cylindrical pressure groove 508, and then the floating connection seat 201 is lowered, so that the spherical pressure head 502 or the cylindrical pressure head 506 is in contact with the surface of the sample. Since the weight of the balancing weight block 110 is balanced with the floating pressing mechanism, the pressure regulating mechanism, the pressing limit mechanism and the first pressing block 501 or the second pressing block 505 of the crushing bearing mechanism, the weight of the floating pressing mechanism, the pressure regulating mechanism, the pressing limit mechanism and the first pressing block 501 or the second pressing block 505 of the crushing bearing mechanism will not cause a significant interference to the pressure on the sample.

[0049] Then, start the locking motor 413. The locking motor 413 drives the double-threaded screw rod 411 to rotate through the worm and worm gear reducer 412. When the double-threaded screw rod 411 rotates, it pushes the locking slider 409 towards the first guide support column 102, so that the anti-slip pad 410 tightly presses the first guide support column 102 to ensure the locking of the stop block 406.

[0050] Then, start the pressure motor 106. The pressure motor 106 drives the driving synchronous pulley 107 to rotate. When the driving synchronous pulley 107 rotates, it drives the synchronous belt 109 to move. When the synchronous belt 109 moves, it pulls the extrusion block 401 downwards. When the extrusion block 401 descends, it squeezes the pressure measurement spring 312 to contract until the extrusion block 401 descends to fit with the stop block 406. At the same time, the pressure measurement spring 312 transfers the pressure to the sample, so that the pressure measurement spring 312 receives the same large pressure. Then, turn off the pressure motor 106. The pressure measurement spring 312 pushes the extrusion block 401 to rise and reset. Then, start the locking motor 413 to reverse and turn it off. When reversing, the locking motor 413 drives the double-threaded screw rod 411 to rotate in the reverse direction through the worm and worm gear reducer 412. When the double-threaded screw rod 411 rotates, it pushes the locking slider 409 to move away from the first guide support column 102, so that the anti-slip pad 410 separates from the first guide support column 102, and the locking is released. Then, lift the floating connection seat 201 upwards to take out the sample, and observe whether the sample is cracked or broken. If it is cracked or broken, the sample is unqualified. If it is not cracked or broken, the sample is qualified. Then, lift the floating connection seat 201 upwards again and test it with a new sample of the same batch.
