Description

Technical Field

[0001] The present application relates to the technical field of concrete strength detection, and in particular to a fixed concrete strength detection device. Background Art

[0002] The outer mold of the automobile cylinder head is a component of the lower mold of the cylinder head gravity casting mold. The basic structure of the cylinder head gravity casting mold is the upper and lower molds, where the upper mold is composed of the mold core, the rear support of the mold core, the front support of the mold core and the mold fixing device, and the lower mold is composed of the base, the inner mold core, the outer mold core and the mold fixing device. Therefore, the outer mold of the automobile cylinder head is a mold component related to the casting process of the cylinder head, and it works together with other parts to ensure the correct shape and quality of the cylinder head.

[0003] A patent with publication number CN215414699U discloses a concrete strength detection device, including a support base and a counterweight plate located directly above the support base. The counterweight plate is located directly above the support base. When the concrete strength test is required, the counterweight plate is lifted to a certain height by a traction rope and a plurality of fixed pulleys, and then the concrete sample plate is placed at the center of the upper surface of the support base. After the traction rope is released, the counterweight plate can start free fall motion, and finally the impact contact can instantly impact the concrete sample plate. According to the momentum theorem, the instantaneous impact force of the impact contact on the concrete sample plate can be calculated, thereby detecting the strength of the concrete.

[0004] However, the above technical solution has the following defects:

[0005] (1) When conducting strength testing on concrete, the prior art usually uses a worker to manually adjust the position of the concrete to be tested so that it is accurately located directly below the strength testing push plate. Since the equipment needs to perform multiple testing steps, the manual adjustment of the position by the worker will reduce the efficiency of the subsequent overall testing process of the equipment. At the same time, during the manual adjustment process, improper operation of the worker will cause the concrete to be placed in an inconsistent position each time, which will lead to uncertainty in equipment testing.

[0006] (2) At the same time, in the process of conventional testing, it is usually necessary to continuously apply pressure to the testing push plate until the concrete to be tested is crushed, so as to accurately judge the strength of the concrete to withstand pressure. However, after the concrete is crushed, the continuous squeezing force will cause the concrete fragments to fly, thereby reducing the safety of the workers in the surrounding testing environment. Utility Model Content

[0007] One purpose of the present application is to guide the overflowed pre-melted aluminum alloy or other metal materials to prevent them from overflowing the lower mold and contaminating the surrounding area of ​​the lower mold and the workbench.

[0008] In order to achieve the above purpose, the technical solution adopted in the present application is: a fixed concrete strength detection device, including a main body bracket, a driving cylinder is installed above the main body bracket, the bottom wall of the main body bracket is fixedly connected to a workbench, the output shaft end of the driving cylinder is fixedly connected to a detection push piece, a limit adjustment mechanism is arranged above the workbench, and air blowing and cleaning mechanisms are symmetrically arranged on both sides of the limit adjustment mechanism.

[0009] Preferably, the limit adjustment mechanism includes a screw rod slidably connected to the upper surface of the workbench, the end of the screw rod away from the workbench is fixedly connected to a placing plate, the outer wall of the screw rod is threadedly connected to a nut, both ends of the nut are symmetrically rotatably connected to connecting rods, the end of the connecting rod away from the nut is rotatably connected to a limit frame, the end of the limit frame away from the connecting rod is fixedly connected to a fixed plate, the upper surface of the limit frame is fixedly connected to a protective cover, the side walls of the fixed plate are evenly fixedly connected to springs, and the end of the spring away from the fixed plate is fixedly connected to a push plate.

[0010] Preferably, a ball screw structure is formed between the screw rod and the nut, and the screw rod is located at the exact center of the workbench.

[0011] Preferably, a slide groove is provided on the upper surface of the workbench at a position corresponding to the connecting rod, and the workbench and the connecting rod are slidably connected via the slide groove.

[0012] Preferably, the end of the limit frame away from the connecting rod is C-shaped, and the overall size of the protective cover is compatible with the placement plate.

[0013] Preferably, the air blowing cleaning mechanism includes a linkage plate fixedly connected to the upper surface of the placement plate, the linkage plate is slidably connected to a piston cylinder at one end away from the placement plate, the outer wall of the piston cylinder is fixedly connected to a bracket, the bracket is fixedly connected to the upper surface of the workbench, the upper end of the piston cylinder is internally connected to a connecting pipe, and the end of the connecting pipe away from the piston cylinder is connected to an exhaust port.

[0014] Preferably, the exhaust port is symmetrically attached to the upper surface of the placement plate, and the linkage plate is initially located at the uppermost end of the piston cylinder.

[0015] Compared with the prior art, the beneficial effects of this application are:

[0016] 1 The push plates on the left and right sides of the placement plate will move synchronously with the connecting rod to automatically adjust the position of the concrete. Automatic adjustment can provide more precise concrete position control to ensure that the position of the concrete sample is accurate during the test, which helps to reduce test errors and improve the reliability and accuracy of the test results. In addition, automatic adjustment can quickly and accurately adjust the position of the concrete, thereby saving time and improving test efficiency. In contrast, manual adjustment may take more time and be affected by the operator's skill level and fatigue.

[0017] 2 When the push plate moves, the spring will reduce the impact force of the push plate through its own rebound force. Excessive impact force will cause deformation or movement of the concrete surface, thereby affecting the accuracy and reliability of the test. Reducing the impact force can reduce this impact, ensure the accuracy of the test data, and improve the credibility of the test.

[0018] 3. The air sucked inside the piston cylinder will be discharged from the exhaust port through the connecting pipe, thereby achieving the effect of automatically cleaning the upper surface of the placement plate. If the upper surface of the automatic placement plate is not cleaned, the debris will affect the next use and even affect the accuracy of the test results. By blowing and cleaning, it can be ensured that the table is clean and free of debris when used next time, and will not cause interference or errors to the work. Cleaning the upper surface of the placement plate can reduce the pollution of dust and debris to the surrounding environment, especially in places with high requirements for the working environment. Keeping it clean can improve the hygiene level of the workplace and improve the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] It should be noted that the terms "first", "second", etc. in the description and claims of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0030] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0031] The prior art has the following defects:

[0032] (1) When conducting strength testing on concrete, the prior art usually uses a worker to manually adjust the position of the concrete to be tested so that it is accurately located directly below the strength testing push plate. Since the equipment needs to perform multiple testing steps, the manual adjustment of the position by the worker will reduce the efficiency of the subsequent overall testing process of the equipment. At the same time, during the manual adjustment process, improper operation of the worker will cause the concrete to be placed in an inconsistent position each time, which will lead to uncertainty in equipment testing.

[0033] (2) At the same time, in the process of conventional testing, it is usually necessary to continuously apply pressure to the testing push plate until the concrete to be tested is crushed, so as to accurately judge the strength of the concrete to withstand pressure. However, after the concrete is crushed, the continuous squeezing force will cause the concrete fragments to fly, thereby reducing the safety of the workers in the surrounding testing environment.

[0034] As an improvement, Figures 1 to 7 As shown, the preferred embodiments of the present application are:

[0035] A fixed concrete strength detection device comprises a main frame 1, a driving cylinder 11 is installed above the main frame 1, a workbench 12 is fixedly connected to the bottom wall of the main frame 1, a detection push piece 13 is fixedly connected to the output shaft end of the driving cylinder 11, a limit adjustment mechanism 2 is arranged above the workbench 12, and air blowing and cleaning mechanisms 3 are symmetrically arranged on both sides of the limit adjustment mechanism 2.

[0036] like Figures 2 to 3 As shown, in this embodiment, the limit adjustment mechanism 2 includes a screw rod 22 slidably connected to the upper surface of the workbench 12, the end of the screw rod 22 away from the workbench 12 is fixedly connected to the placement plate 21, the outer wall of the screw rod 22 is threadedly connected to a nut 23, the two ends of the nut 23 are symmetrically rotatably connected to connecting rods 24, the end of the connecting rod 24 away from the nut 23 is rotatably connected to a limit frame 25, the end of the limit frame 25 away from the connecting rod 24 is fixedly connected to a fixed plate 26, the upper surface of the limit frame 25 is fixedly connected to a protective cover 29, the side wall of the fixed plate 26 is evenly fixedly connected to a spring 27, and the end of the spring 27 away from the fixed plate 26 is fixedly connected to a push plate 28.

[0037] Specifically, the push plates 28 located on the left and right sides of the placement plate 21 will move synchronously with the connecting rod 24, thereby realizing automatic adjustment of the position of the concrete. The automatic adjustment can provide more precise concrete position control to ensure that the position of the concrete sample is accurate during the test, which helps to reduce test errors and improve the reliability and accuracy of the test results. In addition, the automatic adjustment can quickly and accurately adjust the position of the concrete, thereby saving time and improving test efficiency. In comparison, manual adjustment may take more time and be affected by the operator's skill level and fatigue.

[0038] like Figure 4 and Figure 5 As shown, in this embodiment, a ball screw structure is formed between the screw rod 22 and the nut 23, and the screw rod 22 is located at the center of the workbench 12. A sliding groove is provided on the upper surface of the workbench 12 at the position corresponding to the connecting rod 24, and the workbench 12 and the connecting rod 24 are slidably connected through the sliding groove.

[0039] Specifically, the end of the limit frame 25 away from the connecting rod 24 is C-shaped. Therefore, in the process of automatically adjusting the position of the concrete, the stability of its own movement will continue to be maintained. Since the push plate 28 is connected to the fixed plate 26 by the spring 27, when the push plate 28 moves, the spring 27 will reduce the impact force of the push plate 28 through its own resilience. Excessive impact force will cause deformation or movement of the concrete surface, thereby affecting the accuracy and reliability of the test. Reducing the impact force can reduce this influence, ensure the accuracy of the test data, and improve the credibility of the detection.

[0040] like Figure 6 As shown, in this embodiment, the end of the limiting frame 25 away from the connecting rod 24 is C-shaped, and the overall size of the protective cover 29 is compatible with the placement plate 21.

[0041] Specifically, the overall size of the protective cover 29 is adapted to the placement plate 21, so the protective cover 29 as a whole will cover and surround the outside of the placement plate 21. Therefore, when the subsequent detection push piece 13 squeezes and crushes the concrete to be tested, the protective cover 29 will isolate the flying gravel, thereby protecting the staff around the detection equipment. During the process of concrete squeezing and crushing, the gravel will cause damage to the surrounding detection equipment. Isolating the gravel can protect the equipment from the impact of gravel splashing, extend the service life of the equipment, and reduce the cost of maintenance and replacement.

[0042] like Figure 7 As shown, in the present embodiment, the air blowing cleaning mechanism 3 includes a linkage plate 31 fixedly connected to the upper surface of the placement plate 21, the linkage plate 31 is slidably connected to a piston cylinder 32 at one end away from the placement plate 21, the outer wall of the piston cylinder 32 is fixedly connected to a bracket 33, the bracket 33 is fixedly connected to the upper surface of the workbench 12, the upper end of the piston cylinder 32 is internally connected to a connecting pipe 34, the end of the connecting pipe 34 away from the piston cylinder 32 is connected to an exhaust port 35, the exhaust port 35 is symmetrically fitted to the upper surface of the placement plate 21, and the linkage plate 31 is initially located at the uppermost end of the piston cylinder 32.

[0043] Specifically, the air sucked into the piston cylinder 32 will be discharged from the exhaust port 35 through the connecting pipe 34, thereby achieving the effect of automatically cleaning the upper surface of the placement plate 21. If the upper surface of the automatic placement plate 21 is not cleaned, the debris will affect the next use and even affect the accuracy of the detection result. By blowing and cleaning, it can be ensured that the table is clean and free of debris when used next time, and will not cause interference or errors to the work. Cleaning the upper surface of the placement plate 21 can reduce the pollution of dust and debris to the surrounding environment, especially in places with high requirements on the working environment. Keeping it clean can improve the hygiene level of the workplace and improve the working environment.

[0044] The working principle of this application is:

[0045] Limit adjustment mechanism steps:

[0046] When the staff uses the equipment to perform a strength test on the concrete to be tested, the concrete is first placed on the upper surface of the placement plate 21. At this time, the detection equipment is started, the driving cylinder 11 is started and is in working condition, and the output shaft end of the driving cylinder 11 will continue to move downward and drive the detection push piece 13 to move synchronously with it. Since the screw rod 22 is fixedly connected to the placement plate 21, when the above-mentioned detection push piece 13 continues to move downward and fits the surface of the concrete above the placement plate 21, it will drive the screw rod 22 to move downward synchronously with the detection push piece 13. Since a ball screw structure is formed between the screw rod 22 and the nut 23, and the screw rod 22 is located at the exact center of the workbench 12, therefore, when the above-mentioned screw rod 22 moves downward, it will drive the nut 23 threadedly connected to its outer wall to keep rotating. Since the two ends of the nut 23 are symmetrically connected to the connecting rod 24, the end of the connecting rod 24 away from the nut 23 is rotatably connected to the limit frame 25, and The upper surface of the workbench 12 is provided with a slide groove at the position corresponding to the connecting rod 24, and the workbench 12 and the connecting rod 24 are slidably connected through the slide groove. Therefore, when the nut 23 keeps rotating, the connecting rods 24 on both sides will be driven to move closer to the nut 23 along the inner wall of the slide groove. Since the push plate 28 is fixedly connected to the connecting rod 24 through the limit frame 25, the push plates 28 on the left and right sides of the placement plate 21 will move synchronously with the connecting rod 24, thereby realizing automatic adjustment of the position of the concrete. The automatic adjustment can provide more precise control of the concrete position, ensuring that the position of the concrete sample is accurate during the test, which helps to reduce test errors and improve the reliability and accuracy of the test results. In addition, the automatic adjustment can quickly and accurately adjust the position of the concrete, thereby saving time and improving test efficiency. In contrast, manual adjustment may take more time and be affected by the operator's skill level and fatigue.

[0047] Since the end of the limit frame 25 away from the connecting rod 24 is C-shaped, the stability of its own movement will be maintained during the above-mentioned automatic adjustment of the concrete position. Since the push plate 28 is connected to the fixed plate 26 by the spring 27, when the push plate 28 moves, the spring 27 will reduce the impact force of the push plate 28 through its own rebound force. Excessive impact force will cause deformation or movement of the concrete surface, thereby affecting the accuracy and reliability of the test. Reducing the impact force can reduce this influence, ensure the accuracy of the test data, and improve the credibility of the test.

[0048] Since the overall size of the protective cover 29 is adapted to the placement plate 21, the protective cover 29 will cover and surround the outside of the placement plate 21. Therefore, when the subsequent detection push piece 13 squeezes and crushes the concrete to be tested, the protective cover 29 will isolate the flying gravel, thereby protecting the staff around the detection equipment. During the concrete squeezing and crushing process, the gravel will damage the surrounding detection equipment. Isolating the gravel can protect the equipment from the impact of the gravel splashing, extend the service life of the equipment, and reduce the cost of maintenance and replacement;

[0049] Air blowing cleaning mechanism steps:

[0050] Since the placement plate 21 is fixedly connected to the linkage plate 31, when the placement plate 21 moves downward, the linkage plate 31 will move downward synchronously therewith. Since the end of the linkage plate 31 away from the placement plate 21 is slidably connected to the piston cylinder 32, and the linkage plate 31 is initially located at the uppermost end of the piston cylinder 32, when the linkage plate 31 moves downward, the interior of the piston cylinder 32 will absorb external air into itself through the connecting pipe 34. When the detection push piece 13 completes the detection of concrete, the staff will remove the concrete on the upper surface of the placement plate 21. At this time, the squeezing force above the placement plate 21 disappears, and the staff will push the placement plate 21 upward. The piston cylinder 32 moves to its original position. At this time, the air sucked in by the piston cylinder 32 will be discharged from the exhaust port 35 through the connecting pipe 34, thereby achieving the effect of automatically cleaning the upper surface of the placement plate 21. If the upper surface of the automatic placement plate 21 is not cleaned, the debris will affect the next use and even affect the accuracy of the detection result. By blowing and cleaning, it can be ensured that the table is clean and free of debris when used next time, and will not cause interference or errors to the work. In addition, cleaning the upper surface of the placement plate 21 can reduce the pollution of dust and debris to the surrounding environment, especially in places with high requirements on the working environment. Keeping it clean can improve the hygiene level of the workplace and improve the working environment.
