Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering testing technology, and more specifically, to an engineering testing device with a protective structure. Background Technology
[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures.
[0003] A patent with publication number CN217304685U discloses a pressurizing device for testing and inspecting raw materials in highway engineering. The device includes a testing mode switching mechanism and a pressure applying mechanism fixedly installed on top of the testing mode switching mechanism. The testing mode switching mechanism includes a base with ear plates at both ends on both sides. A circular hole for rotating a bidirectional lead screw is centrally located on the facing surfaces of both ear plates. One end of the bidirectional lead screw extends out of the circular hole and is connected to a servo motor fixedly installed on one side of the ear plate. Pressure-bearing mechanisms are threadedly installed between the outer edges of the two bidirectional lead screws. This pressurizing device for testing and inspecting raw materials in highway engineering has the ability to test the compressive strength and flexural strength of cement, significantly reducing equipment procurement costs, saving time and labor, efficiently completing cement testing, and greatly improving the accuracy of cement strength test data. It is highly practical.
[0004] However, when the testing equipment in the aforementioned patent performs compressive strength testing, some of the compressed cement blocks may break under pressure and splash, which could easily cause injury to workers. Furthermore, the equipment may be turned on due to operational errors when placing the test specimen, causing injury to the workpiece and the operator, thus affecting the safety of the equipment during use. Moreover, the equipment lacks the ability to adjust the test specimen during placement, and the placement of the test specimen can only be determined manually. This may result in the center end of the testing head and the center end of the test specimen not being aligned on the same axis, thereby reducing the accuracy of the data during the test specimen testing.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0034] like Figure 1-6 As shown, an engineering testing device with a protective structure includes: a base 1, a bottom plate 2 fixed to the upper surface of the base 1, a top plate 3 disposed directly above the bottom plate 2, a protective shell 4 disposed outside the bottom plate 2 and the top plate 3 and fixed to the base 1, an operation box 5 mounted on the base 1, a display screen 6 and an operation panel 7 disposed on the operation box 5, a protective component 8 disposed on the protective shell 4 and the operation box 5, an extrusion plate 9 and a support plate 10 movably disposed inside the protective shell 4 and respectively disposed above the bottom plate 2 and below the top plate 3, a drive component 11 mounted on the extrusion plate 9, the support plate 10, the bottom plate 2 and the top plate 3, and an adjustment component 12 mounted on the support plate 10;
[0035] The protective component 8 is adapted to cooperate with the protective shell 4 to protect the space between the extrusion plate 9 and the support plate 10, as well as the operation panel 7;
[0036] The drive assembly 11 is adapted to control the upward movement of the extrusion plate 9 and the downward movement of the support plate 10;
[0037] The adjustment component 12 is adapted to adjust the position of the test item placed on the extrusion plate 9. During use, the operator places the cement specimen on the upper surface of the extrusion plate 9. The protective component 8 shields the operation panel 7 during the placement of the cement specimen, effectively preventing accidental operation of the control panel or activation of the equipment, which could cause injury to the workpiece and operator. Furthermore, when testing the cement specimen, the protective shell 4 protects the area around the specimen, preventing fragments from splashing and injuring the operator, thus significantly improving equipment safety. Under the control of the drive assembly 11, the support plate 10 is brought close to the cement specimen. The operation panel 7 controls the adjustment assembly 12 to push the cement specimen from multiple directions, so that the cement specimen is adjusted to the center of the extrusion plate 9. This ensures that the center ends of the extrusion plate 9 and the support plate 10 are aligned with the center end of the cement specimen on the same axis, thereby ensuring that the cement specimen is subjected to uniform force during testing and effectively improving the accuracy of cement specimen testing. After the cement specimen position is adjusted, the operation panel 7 controls the drive assembly 11 to make the extrusion plate 9 move the cement specimen to be tested stably upward and against the support plate 10, so that the cement specimen is compressed until it breaks, thereby obtaining the compressive strength of the cement specimen.
[0038] Optionally, the protective component 8 includes a limiting frame 13 on the front surface of the protective shell 4, a protective door 14 slidably installed between the protective shell 4 and the limiting frame 13 and corresponding to the operation panel 7, an observation window 15 provided on the protective door 14, a support frame 16 fixedly connected to the operation box 5, a handle 17 fixed on the front surface of the protective door 14, and two magnetic blocks 18 respectively installed on the handle 17 and the limiting frame 13;
[0039] The two magnetic blocks 18 are magnetically connected to each other. When the user places the cement block to be tested between the extrusion plate 9 and the support plate 10, the protective door 14 is first pulled by the handle 17, allowing it to move between the limiting frame 13 and the protective shell 4. This releases the obstruction of the detection space between the extrusion plate 9 and the support plate 10, and moves the protective door 14 to the front of the operation box 5, obstructing the operation panel 7. Under the control of the support frame 16, the protective door 14 is kept stable when placed in this position. This prevents accidental touches on the control panel during the placement and adjustment of the cement block, preventing injury to the workpiece and operator due to operational errors in placing the cement block. This is beneficial to the safe use of the equipment and improves the efficiency of operation. To ensure the safety of workers, after the cement block to be tested is placed, the protective door 14 is pulled by the handle 17 to block the testing space between the extrusion plate 9 and the support plate 10. This, together with the protective shell 4, effectively blocks the debris generated by the cement block during pressure testing, preventing debris from splashing onto the workers and causing injury, thus improving work safety. The two magnetic blocks 18 on the handle 17 and the limit frame 13 attract each other, ensuring the stability of the protective door 14 after it is closed to the protective shell 4. When testing the cement block to be tested, the observation window 15 allows workers to easily observe the state of the cement block during the pressure test.
[0040] Optionally, the adjustment assembly 12 includes four sliding sleeves 19 fixed to the lower surface of the support plate 10 and arranged in a circular array, four push rods 20 slidably installed between the four sliding sleeves 19 and the support plate 10, four alignment plates 21 fixedly connected to the four push rods 20, and control components 22 installed on the support plate 10 and the four push rods 20.
[0041] The two adjacent sliding sleeves 19 are arranged perpendicularly to each other. Before the cement block is squeezed, the control component 22 drives several pushers to move synchronously, thereby driving several straightening plates 21 to move closer to each other and push the cement block to be tested, so that the cement block is pressed against the center position of the extrusion plate 9. After the position of the cement block to be tested is adjusted, the positions of the four straightening plates 21 move slightly to release the clamping of the cement block, so as not to affect the compressive strength test of the cement block. In addition, the four straightening plates 21 are close to the cement block, which can also restrict and protect the periphery of the cement block to be tested, effectively preventing the cement block from shifting its position when compressed, thus affecting the quality of the compressive strength test of the cement block.
[0042] Optionally, the control component 22 includes four connecting rods 23 rotatably mounted on the support plate 10 and corresponding to the four push rods 20 respectively; four drive gears 24 fixedly connected to the upper ends of the four connecting rods 23 respectively; four transmission gears 25 fixedly connected to the lower ends of the four connecting rods 23 respectively; four transmission racks 26 fixedly on the four push rods 20 and meshing with the four transmission gears 25 respectively; toothed belts 27 meshing with the four drive gears 24; a bracket 28 fixed to the upper surface of the support plate 10; and a control motor 29 mounted on the bracket 28.
[0043] The output end of the control motor 29 is fixedly connected to one of the connecting rods 23. In use, the control motor 29 operates, driving one of the connecting rods 23 to rotate, thereby causing one of the drive gears 24 and the transmission gear 25 to rotate. Under the meshing transmission of the toothed belt 27, the other three drive gears 24 are controlled to rotate synchronously, and under the drive of the other three connecting rods 23, the other three transmission gears 25 are also driven to rotate synchronously. This allows the four push rods 20, which are fixed to the four transmission racks 26, to move horizontally, so that the four push rods 20 can move synchronously and stably.
[0044] Optionally, the drive assembly 11 includes a control screw 30 threadedly mounted on the top plate 3 and rotatably connected to the support plate 10, a hydraulic cylinder 31 mounted on the bottom plate 2, and guide members 32 disposed on the extrusion plate 9, the support plate 10, the bottom plate 2 and the top plate 3;
[0045] The telescopic end of the hydraulic cylinder 31 is fixedly connected to the lower surface of the extrusion plate 9. In use, the hydraulic cylinder 31 is first controlled to push the extrusion plate 9 slightly upward. Then, the control screw 30 is rotated to drive the support plate 10 to move downward and approach the cement block to be tested. Finally, the hydraulic cylinder 31 is started again to push the extrusion plate 9 to move the cement block upward. Together with the support plate 10, the cement block to be tested is extruded until it is crushed and the compressive strength data of the cement block is obtained.
[0046] Optionally, the guide member 32 includes a plurality of first guide rods 33 fixed in a rectangular array on the upper surface of the support plate 10, a plurality of second guide rods 34 fixed in a rectangular array on the lower surface of the extrusion plate 9, and a plurality of guide grooves 35 formed on the bottom plate 2 and the top plate 3, respectively corresponding to the plurality of first guide rods 33 and the plurality of second guide rods 34.
[0047] A plurality of first guide rods 33 and a plurality of second guide rods 34 are respectively fitted and slidably inserted into a plurality of guide grooves 35. When the extrusion plate 9 and the support plate 10 are controlled to move vertically, the plurality of first guide rods 33 and a plurality of second guide rods 34 will move within the plurality of guide grooves 35, thereby guiding and limiting the movement of the extrusion plate 9 and the support plate 10, thus ensuring the stability of the movement of the extrusion plate 9 and the support plate 10, and avoiding positional deviation of the extrusion plate 9 and the support plate 10 that would affect the detection effect of the cement block.
[0048] Optionally, each of the several positioning plates 21 is fixedly connected to a rubber pad 36 on the side away from the several push rods 20. When the four positioning plates 21 move to clamp the cement block placed on the extrusion plate 9, the rubber pads can buffer and protect the contact between the positioning plates 21 and the cement block, thereby avoiding damage to the cement block when positioning it.
[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
