Description
Technical Field
[0001] The utility model relates to the technical field of special reinforced concrete detection, in particular to a device for detecting the strength of special reinforced concrete. Background Technique
[0002] Special reinforced concrete refers to concrete prepared through special design, using special materials or processes to meet specific engineering requirements. This kind of concrete usually has superior performance compared to ordinary concrete and is used for strengthening or repairing structures to improve the load-bearing capacity, durability or other specific properties of the structures.
[0003] However, before the special reinforced concrete on the market is put into use, it is necessary to send the test specimens to an authoritative laboratory for strength testing of the special concrete. Only when the strength test meets the standard can it be put into use. The equipment for testing the strength of concrete on the market is a pressure testing machine. A pressure testing machine is a laboratory equipment used for testing the mechanical properties of materials. It can apply compressive force to a material sample to determine the mechanical behavior of the material when subjected to axial pressure, such as compressive strength, yield point, elastic modulus, etc.
[0004] When the existing pressure testing machine is in use, it is necessary to place the concrete test specimen at the bearing plate of the testing machine and apply pressure to the concrete test specimen by driving the pressure head to detect whether the strength of the concrete test specimen meets the standard. However, after the concrete test specimen is detected, it is inevitable that the specimen body will crack due to the pressure exceeding the stress point, and the concrete debris will fall on the bearing plate, affecting the accuracy of the next test. When the concrete debris falls on the bearing plate, the operator also needs to clean the bearing plate regularly, which increases the labor intensity of the operator to a certain extent, and at the same time, the efficiency of detecting the strength of concrete also shows a downward trend to a certain extent.
[0005] To solve the above problems, a device for detecting the strength of special reinforced concrete is proposed in this application. Content of the Utility Model
[0006] To solve the problems raised in the above background technique. The utility model provides a device for detecting the strength of special reinforced concrete, which can sweep and concentrate the concrete debris from the bearing plate.
[0007] To achieve the above object, the utility model adopts the following technical solutions: A special reinforced concrete strength detection device, including a base, a pressure testing machine is fixedly connected to the outer side of the top of the base, a pressure head is fixedly connected to the output end of the pressure testing machine, a bearing plate is fixedly connected to the middle of the top of the base, a motor is fixedly connected to the lower part of the front end face of the base, a threaded rod is fixedly connected to the output end of the motor, a moving block is spirally connected to the outer side of the threaded rod, a U-shaped rod is fixedly connected to the front end face of the moving block, a fixed strip is fixedly connected to the end of the U-shaped rod away from the moving block, a brush is fixedly connected to the bottom end of the fixed strip, a guiding groove is opened inside the bearing plate, a jack is opened on the front end face of the base, a damping layer is slidably connected to the front side inside the base, a plug rod is fixedly connected to the inner side of the damping layer, a collecting groove is fixedly connected to the top end of the front side of the plug rod, a triangular plate is fixedly connected to the lower part inside the collecting groove, and a vibration motor is fixedly connected to the middle of the triangular plate.
[0008] As a preferred embodiment of the special reinforced concrete strength detection device of the utility model, the end of the threaded rod away from the motor is rotatably connected to the rear of the inside of the base, the outer side of the moving block is slidably connected to the inside of the base, the front side inside the base is slidably connected to the outer side below the U-shaped rod, the outer side below the brush contacts the upper part of the bearing plate, the top end of the rear of the plug rod contacts the front side inside the base, and the rear end face of the collecting groove contacts the upper part of the front end face of the base. This can not only help clean these debris, keep the testing machine clean and the working environment tidy, but also the slag may accumulate on the bearing plate, affecting the accuracy of the next test. By cleaning the slag, it can ensure that the initial conditions of each test are as consistent as possible, and at the same time reduce the labor intensity of the operator manually cleaning the slag scattered on the bearing plate.
[0009] As a preferred embodiment of the special reinforced concrete strength detection device of the utility model, the number of the motors is two, and the motors are distributed on the left and right sides of the front end face of the base. Grooves are opened on the left and right sides inside the base from front to back, and the threaded rod and the moving block are both located in the grooves on the left and right sides inside the base, so that the two groups of motors drive the fixed strip and the brush to slide back and forth on the bearing plate, improving the stability of the back-and-forth sliding of the fixed strip and the brush.
[0010] As a preferred embodiment of the special reinforced concrete strength detection device of the utility model, circular through holes are opened on the left and right sides of the front side inside the base, and the diameter of the through holes on the front side inside the base matches the cross-sectional diameter of the U-shaped rod. The length of the U-shaped rod at the position parallel to the base is the same as the front-back length of the base, which can reduce the floor area of the structure driving the fixed strip to move while allowing the fixed strip and the brush at the rear of the base to slide forward.
[0011] Preferably, for a special reinforced concrete strength detection device of the present utility model, the longitudinal section shape of the bearing plate is "concave", and the inner area of the bearing plate matches the bottom area of the pressure head. The guiding grooves on the inner side of the bearing plate are arranged from front to back, and the number of guiding grooves is several and evenly distributed on the inner side of the bearing plate, which can concentrate the slag falling on the upper part of the bearing plate inside the bearing plate, avoiding falling on the upper part of the base from the left and right sides of the bearing plate, and the guiding grooves can also facilitate the brush to sweep the slag into the collection groove.
[0012] Preferably, for a special reinforced concrete strength detection device of the present utility model, the aperture and depth of the insertion hole provided on the front end face of the base match the longitudinal section diameter and length of the insertion rod, and the thickness of the damping layer is 3 millimeters. The damping layer can increase the friction between the insertion rod and the insertion hole on the front side inside the base, facilitating the installation and disassembly of the collection groove from the front side of the base.
[0013] Preferably, for a special reinforced concrete strength detection device of the present utility model, the angle at which the triangular plate inclines inside the collection groove is inclined 20 degrees from the middle to the left and right sides, and the bottom length of the triangular plate matches the left and right lengths below the inner side of the collection groove, which can effectively avoid the situation that the slag accumulates at one position inside the collection groove, causing accumulation and then overflow.
[0014] The present utility model has the following beneficial effects:
[0015] For the special reinforced concrete strength detection device designed by the present utility model, through the design cooperation of the motor and the brush, after the concrete specimen is pressurized and detected by the pressure head, the slag generated inside due to the pressure is concentrated and collected in the collection groove. This can not only help clean these fragments, keep the testing machine clean and the working environment tidy, but also the slag may accumulate on the bearing plate, affecting the accuracy of the next test. By cleaning the slag, it can ensure that the initial conditions of each test are as consistent as possible, while reducing the labor intensity of the operator manually cleaning the slag scattered on the bearing plate, improving the detection efficiency of special reinforced concrete to a certain extent, and a triangular plate and a vibration motor are arranged inside the collection groove. The slag falling into the collection groove moves as much as possible to the left and right sides through the vibration of the vibration motor and the inclined surface at the top of the triangular plate, which can effectively avoid the situation that the slag accumulates at one position inside the collection groove, causing accumulation and then overflow.

[0027] In this implementation manner: As disclosed in the background art above, "when the existing pressure testing machine is in use, it is necessary to place the concrete test piece at the bearing plate of the testing machine, and apply pressure to the concrete test piece by driving the pressing head to detect whether the strength of the concrete test piece meets the standard. However, after the concrete test piece is detected, it is inevitable that the test piece body will crack due to the pressure exceeding the stress point, and the concrete debris will fall on the bearing plate, affecting the accuracy of the next test. When the concrete debris falls on the bearing plate, the operator also needs to clean the bearing plate regularly, which increases the labor intensity of the operator to a certain extent, and at the same time, the efficiency of detecting the concrete strength also shows a downward trend to a certain extent."

Then take out the collection trough 9 and insert the insertion rod 14 at the rear end face of the collection trough 9 into the jack 13 on the front side of the base 1. The damping layer 15 on the surface of the insertion rod 14 increases the friction between the insertion rod 14 and the jack 13. Stop when the rear end face of the collection trough 9 contacts the front end face of the base 1. After installation, start the pressure testing machine 2. The pressure head 3 below the pressure testing machine 2 presses and tests the specimen. After the specimen is pressurized and tested, if there are a lot of specimen debris remaining above the bearing plate 4, start the motor 5. The motor 5 drives the threaded rod 11 at the output end to rotate. The moving block 12 outside the threaded rod 11 drives the U-shaped rod 6 at the front end face and the fixing strip 7 at the top of the U-shaped rod 6 to move forward from back to front. The brush hair 8 at the bottom of the fixing strip 7 sweeps above the bearing plate 4. At this time, the debris above the bearing plate 4 is driven by the brush hair 8 along the guiding groove 17 into the collection trough 9 on the front side of the base 1. At this time, the operator turns on the vibration motor 16. The vibration motor 16 vibrates inside the triangular plate 10. The debris falling into the collection trough 9 moves as much as possible to the left and right sides through the vibration of the vibration motor 16 and the inclined plane at the top of the triangular plate 10, which can effectively prevent the debris from concentrating at one position in the collection trough 9, causing accumulation and then overflow. After the debris on the bearing plate 4 is cleaned, reverse the motor 5 to make the fixing strip 7 and the brush hair 8 return to the starting position behind the base 1.
