Description

Technical Field

[0001] The invention relates to the technical field of highway engineering raw material testing and detection, and in particular to a pressurizing device for highway engineering raw material testing and detection. Background Art

[0002] Concrete test blocks are standardized samples used in highway projects to test the strength and durability of concrete. After being cast and cured in standard molds, they are subjected to compression and flexural tests to assess whether the quality of concrete in actual projects meets the design requirements. It is a key link in quality control to ensure the safety and stability of building structures.

[0003] The main purpose of concrete block pressure test is to determine the compressive strength of concrete, which is an important indicator for evaluating concrete quality. Through the test, we can understand the mechanical properties of concrete and provide a basis for engineering design, construction and quality control.

[0004] Chinese patent announcement number CN216051138U discloses a pressurizing device for testing and inspecting raw materials for highway engineering, including a pressurizing device body, a base is provided at the bottom of the pressurizing device body, a top seat is provided at the top of the pressurizing device body, a first pressure detection plate, a second pressure detection plate, a detection cabinet, a baffle and a support column are provided at the top of the base, a hydraulic pump is provided at the top of the top seat, a hydraulic lifting column is provided at the bottom of the hydraulic pump, and a display screen, a pressure indicator light and a switch are provided at the front of the detection cabinet. The pressurizing device for testing and inspecting raw materials for highway engineering blocks the debris generated by cement blocks during pressure testing through the baffle, thereby preventing the debris from splashing onto the workers and causing harm to the workers, thereby improving the safety of the work; however, the above patent document still has the following defects during implementation:

The stress at these points is much greater than the average stress, causing the test block to be destroyed prematurely at these positions, thereby failing to accurately reflect the overall compressive strength of the concrete, resulting in inaccurate test data.

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1, as Figure 1 and Figure 2 As shown, a pressurizing device for testing and detecting raw materials of highway engineering comprises a device shell 1 and a concrete test block 9, a support plate 3 is fixedly connected to the middle side of the upper rear end of the device shell 1, a pressurizing mechanism 4 is fixedly installed at the front of the lower end of the support plate 3, a placement plate 5 is fixedly installed at the middle of the upper end of the device shell 1, a control box 6 is fixedly installed at the upper right end of the device shell 1, a lifting and grinding component 7 is commonly provided at the front end and the inner cavity of the device shell 1, and a drying and flushing component 8 is commonly provided at the left end and the lower part of the inner surface of the device shell 1.

[0036] During the implementation of this embodiment, the concrete test block 9 is placed in the lifting and grinding assembly 7. By operating the control box 6, the concrete test block 9 can be clamped during the lifting process, and the two compressed surfaces of the concrete test block 9 are grinded during the clamping process, so that the two compressed surfaces of the concrete test block 9 can be in a flat state. At the same time, during the grinding process, the drying and flushing assembly 8 flushes the concrete test block 9, and then wet grinding is performed. After grinding, the two compressed surfaces can be flushed so that there are no particles and dust on the two compressed surfaces. At the same time, the drying operation is performed to keep the concrete test block 9 in a normal dry state. Then the concrete test block 9 will be placed on the placement plate 5, and the concrete test block 9 will be pressurized by the pressurizing mechanism 4 on the support plate 3.

In this solution, its pressurizing function is utilized, and its principle will not be elaborated again.

[0039] Specifically, in order to achieve grinding and leveling of the pressurized surface of the concrete test block 9, refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 In this embodiment, the lifting and grinding assembly 7 includes a protective plate 71 which is symmetrically fixed to the front end of the device shell 1, a cabinet door 73 is rotatably connected to the front end of the right protective plate 71, and a collecting frame 72 is fixedly connected to the lower ends of the two protective plates 71. A baffle plate 74 is symmetrically fixed to the front end of the device shell 1, a driving mechanism 75 is provided in the inner cavity of the device shell 1, and clamping mechanisms 76 are provided on the left and right sides of the front end of the driving mechanism 75. A grinding mechanism 77 is provided on the front part of the inner surface of the device shell 1, and a protective mechanism 78 is provided on the middle side of the front part of the inner surface of the device shell 1.

[0040] For further information, see Figure 2 , Figure 5 and Figure 6In this embodiment, the driving mechanism 75 includes a rotating rod 751 that penetrates the left end of the device housing 1 and extends to the right end of the device housing 1 and is rotatably connected in an L-shape. The outer surfaces of the three rotating rods 751 are symmetrically wound and connected with a conveyor belt 752. The upper front side of the left end of the device housing 1 penetrates and extends to the right end of the device housing 1 and is rotatably connected to a limiting roller 753. The left end of the lower rotating rod 751 is fixedly connected to a dual-axis motor 754 that is fixedly connected to the left end of the device housing 1.

[0041] For further information, see Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the two clamping mechanisms 76 include a connecting block 761 fixedly connected to the front ends of the two conveyor belts 752, and an L-shaped hole 768 connected to the inner surface of the device housing 1 is symmetrically opened at the upper end and the front end of the device housing 1. The outer surfaces of the two connecting blocks 761 are slidably connected to the inner surfaces of the L-shaped holes 768. The inner surfaces of the two connecting blocks 761 are slidably connected with rectangular rods 763, and the ends of the two rectangular rods 763 that are close to each other are fixedly connected with clamping plates 764, and the ends of the two rectangular rods 763 that are away from each other are fixedly connected with round block rods 765, and the lower parts of the outer surfaces of the two round block rods 765 are rotatably connected with round balls 767, and the outer surfaces of the two rectangular rods 763 are sleeved with springs 766, and the two ends of the two springs 766 are respectively fixedly connected to the ends of the connecting blocks 761 that are away from each other and the ends of the round block rods 765 that are close to each other, and a positioning plate 762 is fixedly connected to the middle part of the front end of the device housing 1.

[0042] For further information, see Figure 4 and Figure 7 In this embodiment, guide grooves 79 are symmetrically provided at the upper end and the front end of the device housing 1, and the outer surfaces of the two balls 767 are slidably connected to the inner surfaces of the two guide grooves 79 respectively.

[0043] During the implementation process, the cabinet door 73 is opened, and the concrete test block 9 is placed between the two clamping plates 764. At the same time, the rear end of the concrete test block 9 is closely attached to the positioning plate 762, so that the front and rear ends of the concrete test block 9 extend out of the clamping plate 764 by the same distance. At this time, the right end output end of the dual-axis motor 754 is started to drive the rotating rod 751 at the lower part to rotate through the coupling, thereby driving the conveyor belt 752 to move upward, and under the action of the limiting roller 753, the conveyor belt 752 can be ensured to run normally, thereby driving the connecting block 761 The two balls 767 slide on the inner surface of the L-shaped hole 768, and at the same time, drive the ball 767 on the clamping mechanism 76 to slide on the inner surface of the guide groove 79. Since the distance between the two guide grooves 79 changes from being far away from each other to being close to each other, the two balls 767 can be close to each other, and the two rectangular rods 763 can be pushed to slide on the inner surface of the connecting block 761 and approach each other. At the same time, the extrusion spring 766 is in a compressed state, so that the two clamping plates 764 can clamp and fix the left and right ends of the concrete test block 9, which is convenient for subsequent grinding operations.

[0044] The dual-axis motor 754 mentioned above is a mature driving technology device in the prior art, and is a mature driving technology means in the prior art. This solution utilizes it to rotate independently on both sides, and the number of positive and negative rotations on both sides can be adjusted and controlled separately, and it can stop in time after rotating to the set number of circles.

[0045] After the clamping plate 764 mentioned above moves to the upper end of the device housing 1, the lower end of the clamped concrete test block 9 is in the same horizontal plane as the upper end of the placement plate 5, and the concrete test block 9 can be placed at the center of the upper end of the placement plate 5.

[0046] For further information, see Figure 2 , Figure 5 , Figure 6 and Figure 8 In this embodiment, the grinding mechanism 77 includes a rotating rod three 771 fixedly connected to the left output end of the dual-axis motor 754 through a coupling, a transmission rod one 773 is rotatably connected to the front side of the middle part of the right end of the device housing 1 and extends to the left end of the device housing 1, and a transmission rod two 774 is rotatably connected to the right end of the right protective plate 71. A one-way bearing one 772 is fixedly connected to the right part of the outer surface of the rotating rod three 771, and a pulley group one 775 is fixedly connected to the outer surface of the one-way bearing one 772 and the outer surface of the transmission rod one 773. The left parts of the outer surfaces of the transmission rod one 773 and the transmission rod two 774 are fixedly connected to the pulley group two 776, and the middle parts of the outer surfaces of the transmission rod two 774 and the rotating rod three 771 are fixedly connected to grinding rollers 777.

[0047] During the implementation process, after the concrete test block 9 is clamped and fixed, it moves upward under the drive of the driving mechanism 75. At this time, the left end output end of the dual-axis motor 754 is started to drive the rotating rod 3 771 to rotate forward through the coupling. Under the action of the one-way bearing 1 772, the one-way bearing 1 772 drives the pulley group 1 775 to transmit, and drives the transmission rod 1 773 to rotate. At the same time, the rotation of the transmission rod 1 773 drives the transmission rod 2 774 to rotate under the transmission action of the pulley group 2 776, and then drives the two grinding rollers 777 to rotate, and then the two compressed surfaces of the concrete test block 9 can be ground, so that the two compressed surfaces of the concrete test block 9 are in a flat state, so that the stress of the concrete test block 9 can be evenly distributed during the pressure test, accurately reflecting the overall compressive strength of the concrete, and improving the accuracy of the test data.

[0048] The pulley set 1 775 and the pulley set 2 776 mentioned above are both composed of two pulleys and a belt.

[0049] The one-way bearing 772 mentioned above is a mature one-way rotating part in the prior art. This solution utilizes its function of being able to rotate freely in one direction and being locked in the other direction, and its structure and principle will not be elaborated again.

[0050] The straight-line distance between the outer surfaces of the two grinding rollers 777 mentioned above is the straight-line distance between the front and back of the standard concrete test block 9.

[0051] Embodiment 2: Based on Embodiment 1, this embodiment adds a flushing component 8 for flushing, drying and washing the two grinding surfaces of the concrete test block 9 during the grinding process, so as to achieve the purpose of flushing the surfaces of the concrete test block 9 during the grinding process.

[0052] Specifically, in order to rinse the surface of the concrete test block 9 during the grinding process, refer to Figure 2 , Figure 5 , Fig.10 , Fig.11 and Fig.12 In this embodiment, the drying and flushing assembly 8 includes a circular cover 81 fixedly connected to the middle of the left end of the device housing 1, a drying mechanism 82 is provided on the inner surface of the circular cover 81, and a flushing mechanism 83 is provided on the right side of the lower part of the inner surface of the device housing 1.

[0054] For further information, see Figure 2 , Figure 5 , Figure 8 and Fig. 9 In this embodiment, the protective mechanism 78 includes a protective cover 781 fixedly connected to the middle side of the front inner surface of the device housing 1, and a connecting pipe 782 is fixedly connected to the lower middle side of the inner surface of the protective cover 781 and extends to the rear of the inner surface of the collection frame 72. The inner surface of the protective cover 781 is rotatably connected to the outer surface of the transmission rod 773.

[0055] During the implementation process, when the pressure surface of the concrete test block 9 is being polished by the polishing mechanism 77, the water pump 833 is started at this time, so that the water pump 833 can draw water in the water tank 831 into the water outlet pipe 832 and spray water on the outer surfaces of the two polishing rollers 777, so that the polishing rollers 777 can reduce dust by spraying water during the polishing operation. The wet polishing method can reduce the friction between the polishing rollers 777 and the concrete test block 9 to avoid overheating. At the same time, after the polishing operation, the debris remaining on the pressure surface of the concrete test block 9 can be rinsed to ensure that no debris and debris will remain on the pressure surface of the concrete test block 9 before the pressure test, thereby improving the accuracy of the pressure test data. At the same time, the sewage and debris will fall into the collection frame 72 under the action of gravity, and the sewage and debris on the outer surface of the rear polishing roller 777 will also fall into the collection frame 72 under the action of the protective cover 781 and the connecting pipe 782, and be discharged through the discharge pipe in the collection frame 72.

[0056] For further information, see Figure 3 , Fig.11 and Fig.12 In this embodiment, the drying mechanism 82 includes a rotating rod 821 rotatably connected to the inner surface of the circular cover 81, a fan blade 822 is fixedly connected to the right part of the outer surface of the rotating rod 821, a one-way bearing 824 is fixedly connected to the left part of the outer surface of the rotating rod 771, and a pulley group 823 is fixedly connected to the outer surface of the one-way bearing 824 and the outer surface of the rotating rod 771. The upper part of the inner surface of the circular cover 81 penetrates and extends to the front end of the device housing 1 and the right end of the left protective plate 71, and is fixedly connected to an air outlet pipe 825. The lower part of the inner surface of the circular cover 81 penetrates and extends to the lower part of the outer surface of the circular cover 81 and is fixedly connected to an air inlet pipe 826. A heating plate 827 is fixedly installed on the outer surface of the air inlet pipe 826. The inner surface of the air inlet pipe 826 is linearly and equidistantly distributed and fixedly connected to a plurality of blocking plates 828.

[0057] During the implementation process, after the concrete test block 9 has been polished and rinsed, the left end output end of the dual-axis motor 754 is started to drive the rotating rod three 771 to rotate, and then under the action of the one-way bearing two 824, the pulley group three 823 is driven to perform transmission operation, so that the rotating rod four 821 is rotated, and then the fan blades 822 are driven to rotate, so that the rotation of the fan blades 822 sucks air into the circular cover 81 through the air inlet pipe 826, and at the same time, the air is heated by the heating plate 827. The air entering the air inlet pipe will extend the entry time under the action of the blocking plate 828, so that the air has sufficient heating time, and then the air is fully heated and blown out through the air outlet pipe, so that the hot air can dry the outer surface of the washed concrete test block 9, so that the concrete test block 9 remains in a normal dry state.

[0058] The pulley group three 823 mentioned above is composed of two pulleys and a belt.

[0059] The heating plate 827 mentioned above is a mature heating technology means in the prior art and a mature instant heating device in the prior art. In this solution, its heating function is utilized and its structure and principle are not further elaborated.

[0060] The one-way bearing 2 824 mentioned above is a mature one-way rotating part in the prior art. The present solution utilizes its function of being able to rotate freely in one direction and being locked in the other direction. Its structure and principle will not be elaborated. In the present solution, the one-way bearing 1 772 and the one-way bearing 2 824 are locked in opposite directions.

[0061] Working process: When in use, the concrete test block 9 is placed on the clamping mechanism 76. At this time, the concrete test block 9 is clamped and fixed during the process of being lifted upward by the driving mechanism 75, and the pressure surface of the concrete test block 9 is grinded by the grinding mechanism 77. At the same time, the flushing mechanism 83 sprays water on the grinded concrete test block 9, so that the concrete test block 9 is wet-ground. After grinding, the two grinded surfaces of the concrete test block 9 are flushed, and finally the concrete test block 9 is dried by the drying mechanism 82.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.
