Description

Technical Field

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

[0002] Concrete is widely used in the construction industry due to its advantages such as abundant raw materials, low price, high compressive strength and high stability. Concrete samples are usually cast before construction, and the compressive strength and other parameters of the samples are tested to ensure that the cast building meets the requirements.

[0003] The Chinese patent with the publication number CN220626040U discloses a convenient concrete block compression test device, including a support frame, a hydraulic cylinder, a pressure plate and a cleaning device. By setting up the cleaning device, the electric push rod pushes the push plate to push the soil on the storage plate, and cleans the soil on the storage plate to the cleaning groove. Through the adjustment mechanism and the baffle plate 2, the upper end of the cleaning groove is opened while swinging downward along the outer side of the movable rod, so that the soil falls into the collection box for collection, thereby achieving the effect of quickly cleaning the soil. By setting up the adjustment mechanism, the small cylinder is tilted through the fixed column, and then the movable block drives the adjustment plate and the baffle plate 2 to swing downward along the outer side of the movable rod through the small cylinder, thereby achieving the effect of adjusting and controlling the opening and closing of the cleaning groove gap.

[0004] However, in actual use, when the debris of the concrete sample enters the collection box through the cleaning trough, the debris dust and the like will come into contact and collide with the baffle plate 2, and a portion of the debris dust will remain on the surface of the push plate. The remaining debris needs to be manually cleaned, otherwise it will rise to the surface of the cleaning device as the baffle plate 2 closes the cleaning trough, thereby affecting the overall cleanliness of the device and possibly affecting the cleanliness of the experimental environment (air, etc.). That is, the cleaning effect of the above scheme is not good. Utility Model Content

[0005] The utility model aims to provide a concrete compressive strength detection device to solve the problem of poor cleaning effect of the existing device mentioned above.

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

[0007] The machine body has a collecting tank on the top, and a collecting box is inserted into the side wall of the machine body, and the collecting box is connected with the collecting tank;

[0008] A push assembly is installed at one end of the top of the machine body away from the collecting tank;

[0009] The detection mechanism is installed on the top of the machine body and is located between the push assembly and the collection tank;

[0010] The cleaning mechanism includes a U-shaped side panel, a baffle, an electric telescopic rod, a counterweight and bristles. The U-shaped side panel is fixed to the top of the machine body, the collecting trough is located on the inner side of the U-shaped side panel, one end of the baffle is hinged to an end of the collecting trough away from the pushing assembly, the electric telescopic rod is arranged in the machine body, the movable end of the electric telescopic rod extends into the collecting trough, and is slidingly hinged to the side of the bottom of the baffle close to the pushing assembly, the two ends of the counterweight are respectively movably connected with slide rails, the slide rails are installed on the baffle, the bristles are fixed to the bottom of the counterweight, and the bristles are abutted against the baffle.

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

[0012] 1. The concrete sample placed on the machine body can be pushed by the setting of the pushing component, so that the concrete sample is located below the detection mechanism, and the compressive strength of the concrete sample is tested by the detection mechanism to obtain the compressive strength of the concrete. After the tested concrete sample is crushed, the crushed concrete sample can continue to be driven by the pushing component to the top of the cleaning component to complete the cleaning.

[0013] 2. Through the setting of U-shaped side panels, baffles and electric telescopic rods, after the fragments and slag of the concrete sample are moved to the baffle, the baffle can be tilted by shortening the electric telescopic rod to open the collection trough, and then the fragments and slag can be moved into the collection box through the collection trough. The baffle can be closed to seal the collection trough, so that the dust raised inside will not interfere with the external environment. The U-shaped side panels can block the dust raised when the fragments and slag fall into the collection trough to a certain extent.

[0014] 3. By setting the counterweight, slide rail and brush, when the baffle is tilted, the counterweight can drive the brush to scrape and clean the baffle due to its own gravity until the brush moves to the lowest position of the slide rail, thereby improving the cleaning effect at the baffle and eliminating the need for manual cleaning. After the baffle is reset (when it is in a horizontal state), the pushing assembly can push debris and soil into the top of the baffle, so that the brush counterweight is driven by the debris and soil away from the pushing assembly, or the counterweight is driven by manual labor to return to its original position, so that the scraper can still scrape when the collection tank is opened next time.

[0015] The utility model is further configured as follows: connecting shafts are respectively fixed at both ends of the counterweight block, rollers are installed at the ends of the connecting shafts, a step slide groove is provided in the slide rail, the connecting shaft is slidably inserted in the step slide groove, and the rollers roll and abut against the step slide groove.

[0016] The principle and effect of this technical solution: by setting the connecting shaft and the roller, the friction between the counterweight and the slide rail is converted into rolling friction, thereby further reducing the friction force, making it easier for the counterweight to slide due to its own gravity and easier to move due to external drive. By setting the stepped slide groove, the roller can be restricted to the inner side of the slide rail, so that the position of the counterweight can remain stable.

[0017] The utility model is further configured as follows: the cleaning mechanism also includes a reset unit, the reset unit includes a mounting column, a spring rod group and a wedge block, the mounting column is fixed to one end of the top of the baffle plate close to the pushing assembly, the top of the mounting column is hinged to one end of the bottom of the slide rail close to the pushing assembly, one end of the spring rod group is hinged to one end of the top of the baffle plate away from the pushing assembly, the other end of the spring rod group is hinged to one end of the bottom of the slide rail away from the pushing assembly, the wedge block is fixed to one end of the inner side of the U-shaped side plate away from the pushing assembly, when the baffle plate closes the collecting slot, the end of the slide rail away from the pushing assembly abuts against the inclined surface of the wedge block, and the top edge of the end of the slide rail away from the pushing assembly is lower than the top edge of the end of the slide rail close to the pushing assembly.

[0018] The principle and effect of the technical solution: by setting the mounting column, the spring rod group and the wedge block, when the collecting trough is closed (that is, the electric telescopic rod extends to the maximum stroke, and the baffle closes the collecting trough), the slide rail is hinged to the mounting column and the spring rod group, and the spring rod group can be telescoped. When the end of the slide rail away from the pushing assembly abuts against the inclined surface of the wedge block, the spring rod group can be compressed to rotate the slide rail around the hinged end of the mounting column, thereby tilting the slide rail, and then the counterweight block moved to the end of the slide rail close to the pushing assembly can spontaneously move away from the pushing assembly, so that the counterweight block drives the bristles to reset, and at the same time, the dust that has not been swept clean on the baffle can be swept to the other side of the collecting trough for collection.

[0019] The utility model is further configured as follows: a cover plate is also installed on the top of the U-shaped side plate.

[0020] The principle and effect of this technical solution: The setting of the cover plate can block the dust raised when the debris of the concrete sample enters the collection tank, thereby making the external experimental environment cleaner.

[0021] The utility model is further configured as follows: sponge blocks are respectively installed at both ends of the step slide.

[0022] The principle and effect of the technical solution: the sponge block can buffer the counterweight block and the bristles when they slide along the slide rail (by compressing the sponge block to dissipate energy), thereby preventing the counterweight block from violently hitting the guide rail, thereby reducing the service life of the structure. The utility model is further configured as follows: the detection mechanism includes a frame, a hydraulic cylinder and a pressure plate, the frame is installed on the top of the body and is located between the pushing component and the collection tank, the hydraulic cylinder is installed on the top of the inner side of the frame, and the pressure plate is installed at the bottom of the movable end of the hydraulic cylinder.

[0023] The principle and effect of this technical solution: The hydraulic cylinder drives the pressure plate to press down, so that the pressure plate can perform pressure testing on the concrete sample. The hydraulic cylinder provides downward pressure, and the pressure plate performs pressure resistance and data collection and transmission, thereby completing the entire testing process.

[0024] The utility model is further configured as follows: the pushing assembly comprises an electric push rod and a push plate, the electric push rod is installed at one end of the top of the machine body away from the collecting tank, and the push plate is connected to the movable end of the electric push rod.

[0025] The principle and effect of this technical solution are as follows: the push plate is driven by an electric push rod to move, so that the concrete sample placed on the machine body can be pushed to the bottom of the detection mechanism for detection. At the same time, after the detection, the push plate can push the fragments and slag of the concrete sample to the top of the baffle, that is, to the top of the collection tank, so that the fragments and slag can be cleaned by the cleaning mechanism, and most of the debris and dust above the machine body can be scraped off by pushing, so that a certain degree of cleanliness is maintained under the detection mechanism.

[0034] As attached Figure 1-6 As shown, the utility model discloses a concrete compressive strength detection device, including a body 101, a driving component, a detection mechanism and a cleaning mechanism.

[0035] A collecting tank 102 is provided on the top of the body 101.

The detection mechanism includes a frame 301, a hydraulic cylinder 302 and a pressure plate 303. The frame 301 is installed on the top of the body 101 and is located between the pushing assembly and the collection tank 102. The hydraulic cylinder 302 is installed on the top of the inner side of the frame 301. The pressure plate 303 is installed at the bottom of the movable end of the hydraulic cylinder 302. The pressure plate 303 is a lower pressure plate 303 with a pressure sensor, which is a commonly used detection component in this field and does not need to be elaborated in detail.

[0038] When the device is in use, a placement plate made of alloy steel (placed on the body 101) can be placed under the detection mechanism to support the concrete sample, thereby protecting the surface of the body 101 (preventing the body 101 from being scratched when pushing the concrete sample, and the placement plate can be taken out for cleaning during subsequent cleaning). The bottom edge of the push plate 202 is slightly higher than the top edge of the placement plate. If the placement plate is not placed, the bottom edge of the push plate 202 is slightly higher than the surface of the body 101. Bristles 405 can be set at the bottom of the push plate 202, so that the bristles 405 drive fine debris into the collection tank 102.

[0039] The cleaning mechanism includes a U-shaped side panel 401, a baffle 402, an electric telescopic rod 403, a counterweight 404 and bristles 405. The U-shaped side panel 401 is fixed to the top of the body 101. A cover plate 411 is also installed on the top of the U-shaped side panel 401. The collecting tank 102 is located on the inner side of the U-shaped side panel 401. One end of the baffle 402 is hinged to the end of the collecting tank 102 away from the pushing component. The electric telescopic rod 403 is arranged in the body 101. The movable end of the electric telescopic rod 403 extends into the collecting tank 102 and is slidably hinged to the side of the bottom of the baffle 402 close to the pushing component. Slide rails 406 are respectively installed at both ends of the counterweight 404. The slide rails 406 are installed on the baffle 402. The bristles 405 are fixed to the bottom of the counterweight 404, and the bristles 405 are abutted against the baffle 402. Connecting shafts 407 are fixed at both ends of the counterweight block 404 , rollers 408 are installed at the ends of the connecting shafts 407 , a stepped groove 409 is provided in the slide rail 406 , the connecting shaft 407 is slidably inserted in the stepped groove 409 , and the rollers 408 roll and abut against the stepped groove 409 .

[0040] The cleaning mechanism also includes a reset unit, which includes a mounting column 501, a spring rod group 502 and a wedge block 503. The mounting column 501 is fixed to one end of the top of the baffle 402 close to the push assembly, the top of the mounting column 501 is hinged to one end of the bottom of the slide rail 406 close to the push assembly, one end of the spring rod group 502 is hinged to one end of the top of the baffle 402 away from the push assembly, the other end of the spring rod group 502 is hinged to one end of the bottom of the slide rail 406 away from the push assembly, and the wedge block 503 is fixed to one end of the inner side of the U-shaped side plate 401 away from the push assembly. When the baffle 402 closes the collection tank 102, the end of the slide rail 406 away from the push assembly abuts against the inclined surface of the wedge block 503, and the top edge of the end of the slide rail 406 away from the push assembly is lower than the top edge of the end of the slide rail 406 close to the push assembly. Sponge blocks 410 are installed at both ends of the step chute 409.

[0041] The inner side of the U-shaped side plate 401 has a protrusion (such as Figure 5 As shown in FIG. 4 , the protrusion can prevent the concrete sample fragments from pressing against the slide rail 406 when entering the inner side of the U-shaped side plate 401, thereby interfering with the movement of the concrete sample.

[0042] There is a gap between the end of the collecting tank 102 away from the push plate 202 and the end of the baffle 402 away from the push plate 202 (eg, Figure 1 or Figure 2 As shown in the figure), the gap can be used to collect dust when the bristles 406 are brushing back, so as to prevent the accumulation of debris and dust on the side of the U-shaped side plate 401 away from the push plate 202.
