Description

Technical Field

[0001] This invention relates to the field of brick testing equipment technology, specifically to a device for testing the compressive strength of construction brick and stone waste. Background Technology

[0002] In construction projects, the demolition of old buildings and the long-term storage of bricks generate a large amount of brick and stone waste. Construction brick and stone waste can serve municipal landscaping, such as paving walkways and landscaping. For high-performance waste bricks, they can even be used in special projects such as slope protection. Through scientific classification and reasonable processing, brick and stone waste can be transformed from "waste" into "resource," which not only reduces carbon emissions in the construction industry but also contributes to the development of a circular economy. Before bricks and stones are used in building construction, their compressive strength needs to be tested to ensure the reliable construction quality.

[0003] The compressive strength testing of bricks and stones is mainly carried out by sampling. However, the morphology and performance of brick and stone waste vary greatly. Standardized compressive strength testing cannot be performed on bricks and stones with damaged surfaces, while the test results of bricks and stones with good surfaces cannot represent the overall performance of the bricks and stones waste, resulting in large errors in the test results. Therefore, in the existing technology, bricks and stones waste are often transported to the construction site in a unified manner. Before using the bricks and stones waste, the construction workers will indirectly test the compressive strength of the bricks and stones by manually knocking them. Bricks and stones that do not meet the requirements are discarded. This method not only increases the transportation cost of bricks and stones waste, but is also very labor-intensive. Therefore, we propose a device for testing the compressive strength of bricks and stones waste in construction. Summary of the Invention

[0004] This invention provides a device for testing the compressive strength of construction brick and stone waste. This device addresses the problem mentioned in the background art that the compressive strength testing of bricks and stones is mainly conducted through sampling. However, the morphology and performance of brick and stone waste vary greatly. Standardized compressive strength testing cannot be performed on bricks and stone waste with damaged surfaces, while the test results of bricks and stone waste with good surfaces cannot represent the overall performance of the bricks and stone waste, resulting in large errors in the test results. Therefore, in the prior art, bricks and stone waste are often transported to the construction site in a unified manner. Before using the bricks and stone waste, construction workers manually tap the bricks and stone waste to test its compressive strength, and discard the unqualified bricks and stone. This method not only increases the transportation cost of bricks and stone waste, but also consumes a lot of manpower.

[0005] To achieve the above objectives, this solution provides a device for testing the compressive strength of construction brick and stone waste, including a machine base. Several electric rollers are equidistantly arranged on the machine base. A crossbeam is provided at the feeding end of the machine base. A vertical rod is provided on the crossbeam. A first crossbar is installed at the bottom end of the vertical rod. A feeding plate is installed at the feeding end of the machine base. A guide plate is provided on the feeding plate. A second crossbar is installed at the top of the guide plate. The machine platform is equipped with an electric push rod, and an impact block is installed at the bottom end of the telescopic rod of the electric push rod. The machine platform is also equipped with an infrared sensor for detecting bricks and stones.

[0006] Optionally, a pressure plate is installed at the bottom end of the electric push rod telescopic rod, and the impact block is installed on the pressure plate. A pair of impact blocks are provided, and the pair of impact blocks are respectively located directly above the long edge of the brick to be tested.

[0007] Optionally, the vertical rod slides through the crossbeam, and a tension spring is sleeved on the vertical rod, with the other end of the tension spring connected to the crossbeam; A horizontal plate is installed at the top of the vertical rod, and vertical plates are provided at both ends of the horizontal plate. Under normal conditions, the vertical plates abut against the horizontal beam.

[0008] Optionally, a flat plate is installed on the electric push rod telescopic rod, and a lifting plate is hinged to one end of the flat plate near the horizontal plate. The lifting plate is located directly above the horizontal plate, and a first torsion spring is provided at the connection end between the lifting plate and the flat plate. One end of the first torsion spring is connected to the lifting plate, and the other end of the first torsion spring is connected to the flat plate.

[0009] Optionally, a rotating rod is provided on the feeding plate, and the guide plate is mounted on the rotating rod. Under normal conditions, the guide plate is inclined. A second torsion spring is provided on the feeding plate. One end of the second torsion spring is connected to the rotating rod, and the other end of the second torsion spring is connected to the feeding plate.

[0010] Optionally, a collar is fitted on the second crossbar, and the collar makes rolling contact with the bottom surface of the brick to be tested.

[0011] Optionally, a damping block for supporting bricks and stones is provided on the first crossbar, and a third torsion spring is provided inside the damping block. One end of the third torsion spring is connected to the first crossbar, and the other end of the third torsion spring is connected to the damping block.

[0012] Optionally, a fixing block is provided on the feeding plate, an impact rod is slidably inserted on the fixing block, an abutment block is installed at the top of the fixing block, the edges of the abutment block are rounded, a compression spring is sleeved on the impact rod, and the other end of the compression spring is connected to the fixing block.

[0013] Optionally, the bottom end of the impact rod is provided with a mounting plate, a spring plate is detachably mounted on the mounting plate, and a lever is mounted on the rotating rod. The lever is configured as an L-shaped plate, and the lever intermittently contacts the spring plate. A limiting ring is installed on the impact rod, and the limiting ring is located directly below the fixing block.

[0014] Optionally, the feeding plate has a through groove located directly below the abutting block, the feeding plate has several through holes, and baffles are provided on both sides of the feeding plate.

[0015] Through the above technical solution, the construction waste brick and stone compressive strength testing device provided by this solution works as follows: An electric push rod pushes an impact block to impact the waste bricks and stones. If the compressive strength of the waste bricks and stones is high, they will not break. After the test is completed, the electric push rod retracts upwards. At this time, the lifting plate contacts the horizontal plate, and the lifting plate lifts the horizontal plate, making the height of the first horizontal bar higher than the second horizontal bar. The waste bricks and stones tilt, and after tilting, they automatically slide onto the discharge plate. Qualified waste bricks and stones fall along the discharge plate. If… Due to aging, waste bricks and stones undergo pulverization and structural changes, resulting in a decrease in compressive strength. At this point, the impact block can easily crush the pulverized, substandard bricks and stones. The broken pieces then fall along the guide plate between the first and second horizontal bars, thus achieving individual inspection of the waste bricks and stones. Bricks and stones meeting or failing compressive strength requirements are automatically separated, ensuring that only qualified bricks and stones are transported effectively, saving transportation costs. Once the qualified bricks and stones arrive at the construction site, they do not require manual inspection by construction personnel, further saving manpower. In addition, when inspecting waste bricks and stones, the guide plate is pressed downwards, causing it to deflect against the force of the second torsion spring. After the guide plate deflects, the horizontal distance between the second horizontal bar and the first horizontal bar at the top of the guide plate increases. If the waste bricks and stones are shortened due to defects, the shortened waste bricks and stones will fall between the second horizontal bar and the first horizontal bar. Therefore, when testing the compressive strength of bricks and stones, this device can simultaneously further screen the damage of the bricks and stones and exclude waste bricks and stones with obvious length defects. If the surface of the waste bricks and stones is severely powdery, the ends of the waste bricks and stones will be powdery and fall off under the contact of the contact block, which will reduce the length of the waste bricks and stones. Furthermore, the waste bricks and stones will fall off the first and second horizontal bars. Therefore, this device can also specifically detect bricks with certain compressive bearing capacity but severely powdery surfaces and separate them from qualified bricks.

[0029] To make the aforementioned objectives, features, and advantages of this solution more apparent and understandable, the specific embodiments of this solution are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this solution. However, this solution can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this solution. Therefore, this solution is not limited to the specific embodiments disclosed below.

[0030] In the description of this solution, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this solution and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this solution. The terms "first" and "second" are used to distinguish one element from another and do not have sequential or importance. Furthermore, in the following description, when referring to the accompanying drawings, the same reference numerals in different drawings indicate the same or similar elements, which will not be repeated here.

[0031] In this solution, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this solution based on the specific circumstances.

[0032] According to some embodiments of this solution, a device for testing the compressive strength of construction brick and stone waste is provided, for reference. Figures 1 to 11 As shown, the device for testing the compressive strength of construction waste bricks and stones includes a machine base 101. Several electric rollers 102, which are gear rollers, are equidistantly arranged on the machine base 101. A crossbeam 201 is installed at the discharge end of the machine base 101, and a vertical rod 202 is installed on the crossbeam 201. A first horizontal rod 203 is installed at the bottom end of the vertical rod 202. A discharge plate 301 is installed at the discharge end of the machine base 101, and a guide plate 305 is installed on the discharge plate 301. A guide plate 305 is mounted on the top of the guide plate 305. The machine is equipped with a second crossbar 306, wherein the horizontal distance between the first crossbar 203 and the second crossbar 306 is less than half the length of the brick. In addition, an electric push rod 103 is installed on the machine base 101, and an impact block 106 is installed at the bottom of the telescopic rod of the electric push rod 103. An infrared sensor 104 for detecting bricks is also installed on the machine base 101. The infrared sensor 104 is electrically connected to the signal input terminal of the DSP controller, and the electric push rod 103 is electrically connected to the signal output terminal of the DSP controller.

[0033] Thus, at the construction site where waste bricks and stones are piled up, workers place the waste bricks and stones sequentially onto the electric rollers 102. Through the conveying action of the electric rollers 102 and the guidance of the guide plates, the waste bricks and stones are separated from the last electric roller 102 in sequence, and move onto the first horizontal bar 203 and the second horizontal bar 306. At this point, the waste bricks and stones are directly below the impact block 106. The infrared sensor 104 detects that the waste bricks and stones are in place, and the electric push rod 103 pushes the impact block 106 to impact the waste bricks and stones. When bricks and stones are impacted, if the compressive strength of the waste bricks and stones is high, the waste bricks and stones will not break. The next waste brick and stone will push the qualified bricks and stones off. The qualified waste bricks and stones fall along the feed plate 301. If the waste bricks and stones undergo structural changes due to aging and pulverization, the compressive strength of the waste bricks and stones will decrease. At this time, the impact block 106 can easily crush the pulverized unqualified bricks and stones. The broken unqualified bricks and stones fall along the guide plate 305 between the first crossbar 203 and the second crossbar 306.

[0034] Additionally, please refer to Figure 2The bottom end of the electric push rod 103 telescopic rod is equipped with a pressure plate 105, and an impact block 106 is installed on the pressure plate 105. There is a pair of impact blocks 106, and the pair of impact blocks 106 are located directly above the long edge of the brick to be tested. Since the weathering of waste bricks and stones develops from the outside to the inside, the surface aging phenomenon of waste bricks and stones is more obvious. In particular, the structural performance of the edge part of the waste bricks and stones changes most significantly. Therefore, the impact block 106 targets the edge part of the waste bricks and stones with targeted impact. If the aging degree of the waste bricks and stones is high, the impact block 106 will break the edge of the bricks and stones, and stress concentration areas will appear on the edge of the bricks and stones, making the bricks and stones more likely to break, thereby reducing missed detections.

[0035] Please refer to Figure 2 , Figure 3 The vertical rod 202 slides through the horizontal beam 201. A tension spring 206 is sleeved on the vertical rod 202. The other end of the tension spring 206 is connected to the horizontal beam 201. A horizontal plate 205 is installed at the top of the vertical rod 202. Vertical plates 207 are set at both ends of the horizontal plate 205. Under normal conditions, the vertical plates 207 are in contact with the horizontal beam 201.

[0036] Please refer to Figure 6 , Figure 7 A flat plate 107 is installed on the telescopic rod of the electric push rod 103. A lifting plate 108 is hinged to one end of the flat plate 107 near the horizontal plate 205. The lifting plate 108 is located directly above the horizontal plate 205. A torsion spring 110 is provided at the connection end between the lifting plate 108 and the flat plate 107. One end of the torsion spring 110 is connected to the lifting plate 108, and the other end of the torsion spring 110 is connected to the flat plate 107.

[0037] Therefore, when the electric push rod 103 extends downwards, the lifting plate 108 contacts the horizontal plate 205. Since the vertical plates 207 at both ends of the horizontal plate 205 contact the crossbeam 201, the horizontal plate 205 is stationary. This allows the lifting plate 108 to overcome the spring force of the first torsion spring 110 and deflect. As the electric push rod 103 continues to move downwards, the lifting plate 108 passes over the horizontal plate 205 and is located directly below it. After the waste bricks and stones are inspected, the electric push rod 103 retracts upwards. At this time, the lifting plate 108 contacts the horizontal plate 205 again, and the lifting plate 108 lifts the horizontal plate 205. The horizontal plate 205 further drives the vertical rod 202 and the first horizontal rod 203 to move upwards, making the height of the first horizontal rod 203 higher than that of the second horizontal rod 306. The qualified waste bricks tilt (see...). Figure 10 The qualified waste bricks are tilted and automatically slide onto the feed plate 301 to prevent them from clogging the subsequent bricks.

[0038] Through the above technical solution, the construction waste brick and stone compressive strength testing device provided in this solution, when in use, the electric push rod 103 pushes the impact block 106 to impact the waste bricks and stones. If the compressive strength of the waste bricks and stones is high, the waste bricks and stones will not break. After the test is completed, the electric push rod 103 retracts upward. At this time, the lifting plate 108 abuts against the horizontal plate 205, and the lifting plate 108 lifts the horizontal plate 205. The horizontal plate 205 further drives the vertical rod 202 and the first horizontal rod 203 to move upward, so that the height of the first horizontal rod 203 is higher than that of the second horizontal rod 306. The waste bricks tilt, and after tilting, the waste bricks automatically slide down to the unloading plate 3. On the 01st floor, qualified waste bricks and stones fall along the feed plate 301. If the waste bricks and stones undergo structural changes due to aging and pulverization, their compressive strength decreases. At this time, the impact block 106 can easily crush the pulverized unqualified bricks and stones. The broken unqualified bricks and stones then fall along the guide plate 305 between the first crossbar 203 and the second crossbar 306, thus realizing the one-by-one inspection of waste bricks and stones. The bricks and stones with qualified and unqualified compressive strength are automatically separated. Subsequent transportation of bricks and stones only effectively transports qualified bricks and stones, saving transportation costs. After the qualified bricks and stones are delivered to the construction site, there is no need for construction personnel to knock and inspect them, thus saving manpower.

[0039] It should be noted that the machine tool 101 is equipped with a motor for driving the electric roller 102. The electric roller 102 has belt rollers at both ends, and adjacent electric rollers 102 are connected by belt drive. The motor driving the electric roller 102 is existing technology. The specific structure and principle of the motor driving the electric roller 102 are well known to those skilled in the art and will not be described in detail here.

[0040] In some implementations of this solution, reference is made to Figure 6 , Figure 8 As shown, a rotating rod 313 is provided on the feeding plate 301, and a guide plate 305 is installed on the rotating rod 313. Under normal conditions, the guide plate 305 is inclined. A second torsion spring 317 is provided on the feeding plate 301. One end of the second torsion spring 317 is connected to the rotating rod 313, and the other end of the second torsion spring 317 is connected to the feeding plate 301. In addition, a collar 312 is sleeved on the second crossbar 306, and the collar 312 makes rolling contact with the bottom surface of the brick to be tested.

[0041] Therefore, when the electric push rod 103 pushes the impact block 106 to apply pressure to the waste bricks, the waste bricks will squeeze the guide plate 305 downwards, causing the guide plate 305 to deflect against the elastic force of the second torsion spring 317. After the guide plate 305 deflects, the horizontal distance between the second crossbar 306 and the first crossbar 203 at the top of the guide plate 305 increases. If the waste bricks are shortened due to defects, the increased horizontal distance between the second crossbar 306 and the first crossbar 203 will cause the damaged waste bricks to fall between the second crossbar 306 and the first crossbar 203. Therefore, when testing the compressive strength of the bricks, this device can simultaneously further screen the damage of the bricks and exclude waste bricks with obvious length defects.

[0042] Additionally, please refer to Figure 6 , Figure 9 During the inspection of waste bricks and stones, the guide plate 305 will deflect, and as the horizontal distance between the second horizontal bar 306 and the first horizontal bar 203 increases, the height of the second horizontal bar 306 will be lower than the height of the first horizontal bar 203. At this time, the waste bricks and stones are in an inclined position. In order to prevent the waste bricks and stones from tilting and slipping, a damping block 204 is provided on the first horizontal bar 203 to support the bricks and stones. A third torsion spring 109 is provided inside the damping block 204. One end of the third torsion spring 109 is connected to the first horizontal bar 203, and the other end of the third torsion spring 109 is connected to the damping block 204. Therefore, when the waste bricks and stones are tilted, the damping block 204 always keeps in contact with the waste bricks and stones through deflection. There is friction between the contact surface between the damping block 204 and the waste bricks and stones, which prevents the waste bricks and stones from tilting and slipping during inspection, thereby ensuring the smooth completion of the inspection.

[0043] In some implementations of this solution, reference is made to Figure 5 As shown, a fixing block 307 is provided on the feeding plate 301, an impact rod 308 is slidably inserted on the fixing block 307, an abutment block 309 is installed on the top of the fixing block 307, the edges of the abutment block 309 are rounded, a compression spring 314 is sleeved on the impact rod 308, and the other end of the compression spring 314 is connected to the fixing block 307.

[0044] In addition, an installation plate 315 is provided at the bottom of the impact rod 308. A spring plate 310 is detachably installed on the installation plate 315. A lever 311 is installed on the rotating rod 313. The lever 311 is an L-shaped plate. The lever 311 intermittently contacts the spring plate 310. A limit ring 316 is installed on the impact rod 308. The limit ring 316 is located directly below the fixing block 307.

[0045] Furthermore, the feeding plate 301 has a through groove 304 located directly below the contact block 309, and the feeding plate 301 has several through holes 303. Baffles 302 are respectively provided on both sides of the feeding plate 301.

[0046] It should be noted that for some waste bricks and stones with severely powdery surfaces but relatively intact internal structural strength, such bricks and stones can pass the compressive strength test of this device. However, during transportation, the powdery structure on the surface of such bricks and stones will continue to fall off, causing the bricks and stones to lose their block shape. Once the bricks and stones lose their block shape, they can no longer be reused.

[0047] Therefore, during the inspection of waste bricks and stones, the guide plate 305 will deflect. The guide plate 305 drives the lever 311 to rotate via the rotating rod 313. When the lever 311 rotates, it will contact the spring plate 310. When the lever 311 contacts the spring plate 310, the lever 311 drives the impact rod 308 to move away from the waste bricks and stones via the spring plate 310. At the same time, the compression spring 314 set on the impact rod 308 is compressed and stores force. When the lever 311 passes the spring plate 310, the compression spring... 314 is released quickly. The compression spring 314 drives the impact rod 308 to drive the contact block 309 to contact the end of the waste brick. If the surface of the waste brick is severely powdered, the end of the waste brick will be powdered and fall off under the contact of the contact block 309, which reduces the length of the waste brick. Furthermore, the waste brick falls off through the first horizontal bar 203 and the second horizontal bar 306. Therefore, this device can also specifically detect bricks with certain compressive bearing capacity but severely powdered surfaces and separate them from qualified bricks.

[0048] The preferred embodiments of this solution have been described in detail above with reference to the accompanying drawings. However, this solution is not limited to the specific details in the above embodiments. Within the scope of the technical concept of this solution, various simple modifications can be made to the technical solution, and these simple modifications all fall within the protection scope of this solution.

[0049] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this solution will not describe the various possible combinations separately.

[0050] Furthermore, various implementations of this solution can be combined in any way, as long as they do not violate the spirit of this solution, they should also be regarded as the content disclosed in this solution.
