Description

Technical Field

[0001] The utility model belongs to the technical field of material detection, and in particular relates to a device for detecting the compressive strength of building materials. Background Art

[0002] Building materials are a general term for materials used in civil engineering and construction projects. They can be divided into structural materials, decorative materials and special materials. For structural materials that bear loads, the performance of the materials determines the strength and life of the project, so the testing of material performance is very important.

[0003] A Chinese patent with publication number CN219675708U discloses a device for detecting the compressive strength of building steel structures. The device can shield the splashing steel structures and debris through a protective cover to reduce the possibility of the splashing steel structures and debris impacting the workers and improve the safety of the workers' work; the sample is fixed by a clamping mechanism, which can improve the fixing stability of the sample on the placement plate when the pressure detection mechanism presses down the sample, thereby improving the accuracy of the test result; the debris intercepted by the protective cover can be transported to the waste collection box through the waste outlet through the cleaning mechanism for collection, which can reduce the labor intensity of the workers and is faster than manual cleaning of the debris, thereby improving the overall work efficiency.

[0004] However, in actual use, since the clamping mechanism drives the pressure plate to clamp the sample by rotating the bolt, the inspector needs to control the multiple screws on both sides separately to achieve the clamping effect, which is cumbersome. After the pressure test is completed, the inspector needs to manually rotate the screw to drive the pressure plate and the screw to make way for the scraper and the connecting plate. In summary, the above device is cumbersome to use, and the inspector needs to repeatedly adjust the position of the clamping mechanism. Utility Model Content

[0005] The utility model aims to provide a device for testing the compressive strength of building materials, so as to solve the problem that the prior art mentioned above is relatively cumbersome in use.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a building material compressive strength testing device, comprising

[0007] A base, a protective cover is fixed on the base, and a pressure resistance detection mechanism is installed above the protective cover;

[0008] The clamping mechanism comprises two symmetrically arranged clamping units, the clamping unit comprises a driving plate, a fixing plate, a guide rod, a clamping plate, a driving rod, a limit block, a driving spring and a return spring, the fixing plate is fixed on the base, the two ends of the guide rod are respectively fixed to the fixing plate and the protective cover, the driving plate is slidably arranged on the base and slidably sleeved on the guide rod, the return spring is sleeved on the guide rod, and the two ends are respectively abutted against the driving plate and the protective cover, a through hole is provided on the side wall of the protective cover, one end of the driving rod passes through the driving plate and is fixed to the limit block, the other end of the driving rod passes through the through hole and is fixed to the clamping plate, the clamping plate is slidably arranged in the protective cover, the driving spring is sleeved on the driving rod, and the two ends are respectively abutted against the driving plate and the clamping plate;

[0009] A driving mechanism, the driving mechanism is used to drive the driving plate to slide along the guide rod;

[0010] A cleaning mechanism is used to clean the inside of the protective cover.

[0011] The principle and effect of this technical solution:

[0012] 1. During clamping, the driving plates are controlled on both sides to make the driving plates close to the protective cover, so that the driving plates squeeze the driving springs and the return springs. Since the driving springs abut against the clamping plates, the compressed driving springs transfer the pressure to the clamping plates, thereby driving the clamping plates to slide in the protective cover, thereby clamping the specimen. Since the return springs are compressed and abut against the driving plates and the protective cover, after the restriction on the driving plates is released, the elastic force of the return springs drives the driving plates away from the protective cover, thereby resetting the driving plates. The driving plates abut against the limit blocks and the elastic force of the driving springs to drive the clamping plates to reset, thereby not interfering with the work of the cleaning mechanism.

[0013] 2. The position of the driving plate is controlled by the driving mechanism, so that the clamping mechanism does not need manual control when clamping the sample, which saves manpower and makes the operation simpler and more convenient.

[0014] 3. The compression resistance of the clamped sample is tested through the compression testing mechanism, and it is safer through the protection of the protective cover. The setting of the cleaning mechanism can facilitate the cleaning of debris in the protective cover, thereby improving the cleanliness.

[0015] The utility model is further configured as follows: the compression detection mechanism includes a fixed rod, a top plate, a hydraulic cylinder and a detection pressure block, the fixed rod is fixed on the base, the top plate is fixed on the fixed rod, the hydraulic cylinder is installed on the top plate, and the hydraulic rod of the hydraulic cylinder passes through the top plate and is fixed to the detection pressure block.

[0016] The principle and effect of this technical solution: The hydraulic rod of the hydraulic cylinder drives the detection pressure head to adjust the position, so as to test the compressive capacity of the sample in the protective cover.

[0017] The utility model is further configured as follows: the driving mechanism includes a connecting rod, a block, a cover plate, a downward pressure spring and a wedge block, the top of the connecting rod is fixed to the block, the bottom of the connecting rod passes through the top plate and is fixed to the cover plate, the cover plate is slidably mounted on the hydraulic rod of the hydraulic cylinder, and the bottom of the cover plate abuts against the top of the detection pressure block, the downward pressure spring is mounted on the connecting rod, and the two ends are respectively abutted against the cover plate and the top plate, the wedge block is fixed to the side wall of the cover plate, the bottom of the wedge block extends to below the bottom of the cover plate, and the inclined surface of the wedge block corresponds to the top of the driving plate away from the protective cover.

[0018] The principle and effect of the technical solution are as follows: because the cover plate is slidably mounted on the hydraulic rod, and because of the pressure of the downward pressure spring, the device can control the height of the detection pressure block when driving the hydraulic cylinder, thereby adjusting the height of the cover plate and the wedge block, and when the cover plate abuts against the protective cover, due to the limitation of the protective cover, the downward pressure spring cannot continue to drive the cover plate to move downward, so the detection pressure head can continue to move downward under the drive of the hydraulic cylinder, thereby completing the downward pressure detection work, and the cover plate and the wedge block are driven downward by the rebound force of the downward pressure spring, so that the cover plate can drive the wedge block to move downward in the detection device. The cover plate is driven to move upward by the detection pressure head, and the downward pressure spring is compressed at the same time, so that the cover plate can drive the wedge block to leave the driving plate, so that the driving plate can be automatically reset under the elastic force of the reset spring, so that the existence of the clamping plate will not affect the work of the cleaning mechanism, the continuous working ability is strong, and the operation is simple and convenient.

[0019] The utility model is further configured as follows: a guide sliding surface is formed on the top of the driving plate at a side away from the protective cover, and the guide sliding surface corresponds to the inclined surface of the wedge-shaped block.

[0020] The principle and effect of the technical solution: the setting of the guide sliding surface enables the wedge block to drive the driving plate to move more conveniently and stably when driving downward, thereby making the device more stable and convenient to use.

[0021] The utility model is further configured as follows: the cleaning mechanism includes a cylinder and a scraper, the cylinder is fixed on a base, a push rod of the cylinder passes through a protective cover and is fixed to the scraper, the scraper is slidably arranged in the protective cover, the sliding direction of the scraper is perpendicular to the sliding direction of the driving plate, and a slag discharge hole is opened on a side of the protective cover away from the cylinder.

[0022] The principle and effect of this technical solution: the scraper is driven by the cylinder to slide in the protective cover, so that the scraper can push the sample debris in the protective cover after the clamping mechanism is reset, thereby pushing the sample debris out of the slag discharge hole to facilitate the next test without manual removal of the debris.

[0023] The utility model is further configured as follows: a slag discharge groove corresponding to the slag discharge hole is opened on the base, and a collection box is placed in the slag discharge groove.

[0024] The principle and effect of the technical solution: The arrangement of the slag discharge trough and the collection box enables the debris and waste slag swept out by the cleaning mechanism to be effectively collected, thereby maintaining the cleanliness of the base.

When the driving plate 401 is not subjected to external force, the clamping plate 404 abuts against the inner wall of the protective cover 301, and the distance between the two clamping plates 404 is greater than the length of the scraper 602, so it will not interfere with the cylinder 601 pushing the scraper 602 to move.

The top of the connecting rod 501 is fixed to the block 502, the bottom of the connecting rod 501 passes through the top plate 202 and is fixed to the cover plate 503, the cover plate 503 is slidably mounted on the hydraulic rod of the hydraulic cylinder 203, and the bottom of the cover plate 503 abuts against the top of the detection pressure block 204, the downward pressure spring 504 is mounted on the connecting rod 501, and the two ends abut against the cover plate 503 and the top plate 202 respectively, the wedge block 505 is fixed to the side wall of the cover plate 503, the bottom of the wedge block 505 extends to below the bottom of the cover plate 503, and the inclined surface of the wedge block 505 corresponds to the top of the side of the driving plate 401 away from the protective cover 301, wherein the connecting rod 501, the downward pressure spring 504 and the block 502 are set in four groups, and all It is arranged around the hydraulic rod, the downward pressure spring 504 is a compression spring, and the pressure is much greater than the return spring 408 and the driving spring 407, the lateral width of the cover plate 503 corresponds to the protective cover 301, and the longitudinal length of the cover plate 503 is greater than the longitudinal length of the protective cover 301, there are four wedge blocks 505, and they are evenly distributed on the front and rear side walls of the cover plate 503, and are located at the left and right ends, and a sealing plate 506 is also fixed to the right side wall of the cover plate 503, the sealing plate 506 corresponds to the slag discharge hole 303, and the bottom of the sealing plate 506 extends to below the bottom of the cover plate 503, when the cover plate 503 is pressed against the protective cover 301, the detection pressure head starts to move downward relative to the cover plate 503, and the top of the driving plate 401 away from the protective cover 301 is provided with a guide sliding surface 409, and the guide sliding surface 409 corresponds to the inclined surface of the wedge block 505.

[0039] The specific implementation process is as follows:

[0040] When using the device, place the sample in the center of the protective cover 301, and then control the hydraulic cylinder 203 to drive the hydraulic rod to push the detection pressure head downward. Driven by the downward pressure spring 504, the cover plate 503 is pressed downward accordingly. When the inclined surface of the wedge block 505 abuts against the guide sliding surface 409 of the driving plate 401, since the elastic force of the downward pressure spring 504 is greater than the return spring 408 and the driving spring 407, the wedge block 505 presses against the guide sliding surface 409, thereby driving the driving plate 401 to contact the driving spring 407. 7 and the return spring 408 are compressed, thereby driving the clamping plates 404 on both sides to clamp the sample until the bottom of the cover plate 503 is pressed against the protective cover 301, and the cover plate 503 cannot move further. At this time, the sample is clamped, and the sealing plate 506 covers the slag discharge hole 303. The hydraulic cylinder 203 continues to drive the hydraulic rod to press down, so that the detection pressure head moves relative to the cover plate 503, so as to detect the compressive capacity of the sample. The compressive capacity of the sample is collected by the detection pressure head, so as to obtain the compressive strength of the sample.

[0041] After the detection is completed, the detection pressure head is driven to rise by driving the hydraulic rod, so that the detection pressure head drives the cover plate 503 to compress the downward spring 504, thereby driving the cover plate 503 to rise, and the cover plate 503 drives the wedge block 505 and the sealing plate 506 to leave the driving plate 401 and the protective cover 301. Due to the departure of the wedge block 505, the reset spring 408 drives the driving plate 401 to reset, and then drives the clamping plate 404 away from the sample, so that the inner space of the protective cover 301 is opened, and the departure of the sealing plate 506 opens the slag discharge hole 303. By starting the cylinder 601, the scraper 602 can be driven to push the debris inside the protective cover 301, thereby pushing the debris from the slag discharge hole 303 into the collection box 103, thereby completing the detection.

It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical scheme of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
