Description

Technical Field

[0001] This utility model relates to the field of building material testing equipment, and in particular to a safety testing device for construction engineering materials. Background Technology

[0002] In the construction engineering field, material safety testing is a crucial step in ensuring the quality and safety of building projects. With the booming development of the construction industry, various new building materials are emerging. These materials must undergo rigorous safety testing before being put into use to ensure they meet the load-bearing requirements, durability requirements, and safety requirements during use. Existing construction material safety testing equipment is diverse, ranging from simple mechanical performance tests to complex comprehensive testing devices. However, in practical applications, many testing devices suffer from common problems, such as insufficient flexibility in adjusting the testing position and inadequate stability and adaptability of the clamping device. These issues, to some extent, affect the accuracy and efficiency of the testing results.

[0003] In the prior art, Chinese patent document CN220729843U discloses a safety testing device for construction materials. This device comprises a worktable, a position adjustment component, a movement adjustment component, and a fixing component. The position adjustment component includes a moving plate, and the movement adjustment component includes a second motor. The output shaft of the second motor passes through the outer wall of the moving plate and is rotatably connected to the inner wall of the moving plate. By controlling the second motor, a first lead screw rotates within the inner wall of the moving plate, thereby moving a sliding plate, which is threaded to the outer edge of the first lead screw and slidably connected to the inner wall of the moving plate. This causes the fixing component on the outer wall of the sliding plate to move, thus adjusting the position of the fixing component. Then, by manually rotating the fixing rods, the distance between the fixing rods can be adjusted, allowing the fixing rods to clamp and fix the building material placed between the two fixing rods. However, consistent with conventional technology, position adjustment relies solely on the interaction between a single lead screw and the sliding plate, resulting in limited adjustment direction and range. Screw drives typically only enable linear movement. When faced with materials of complex shapes or requiring special detection positions, it is difficult to accurately move the detection components to the appropriate position, failing to meet the requirements for multi-dimensional and flexible detection position adjustment. This greatly limits the applicable scenarios of the detection equipment and results in poor practicality. Therefore, this utility model discloses a construction engineering material safety detection device to solve the problem of insufficient flexibility in detection position adjustment in the prior art.

Furthermore, guide strips and guide grooves ensure the stability of the support block movement, and multiple sets of support blocks provide stable support for the L-shaped clamping plate. This design enables the clamping assembly to stably and accurately clamp materials of various shapes and sizes, whether square, round, or other irregular shapes, achieving reliable clamping and fixation, ensuring material stability during testing, and improving the reliability of test results.

[0016] This utility model discloses a construction material safety testing equipment with a reasonable overall structural design, tight cooperation between components, convenient operation, and low maintenance costs. Components such as the loading plate, support columns, and support frame provide a stable support platform for the testing equipment, ensuring its stability during operation. The reasonable layout of the adjustment and clamping components makes the equipment simple and easy to understand, allowing operators to quickly learn how to use it. Compared with existing technologies, this utility model avoids complex operating procedures and cumbersome maintenance steps. For example, when adjusting the detection position, multi-directional movement adjustment can be achieved simply by rotating the first and second screws; when clamping materials, the clamping operation can be easily completed by rotating the first handwheel. This simple and easy-to-use design not only reduces the difficulty of operation but also reduces equipment failures caused by improper operation, thereby reducing equipment maintenance costs. At the same time, the reasonable structural design also facilitates daily maintenance and repair, improving the equipment's service life and economic efficiency. Attached Figure Description

[0027] This utility model provides, for example Figures 1 to 5The invention discloses a construction material safety testing device, comprising: a loading plate 1, with support columns 2 evenly arrayed on the lower end face of the loading plate 1, and a support frame 3 installed at opposite positions on the upper two ends of the loading plate 1. An adjustment and testing component is installed on the top of both support frames 3, used to adjust the position of the testing device; a clamping component is installed in the middle of the upper end face of the loading plate 1, used to clamp the object to be tested. This adjustment and testing component achieves multi-dimensional and flexible position adjustment. A first sliding groove on the lower end face of the first mounting frame 4 engages with a first sliding block, and a second sliding groove on the lower end face of the second mounting frame 15 engages with a second sliding block, providing a basis for the movement of the testing component in different directions. Rotating the first screw 25 moves the second mounting frame 15 horizontally; rotating the second screw 17 moves the connecting block 20 horizontally on the second mounting frame 15. This multi-directional adjustment method allows the detection component to be precisely moved to any desired position on the material to be tested, regardless of whether the material is regular or irregular in shape. This achieves accurate positioning, greatly expanding the applicability of the testing equipment and ensuring the accuracy of the test results. The clamping assembly of this invention employs a bidirectional screw 7 and an L-shaped clamping plate 13. Rotating the first handwheel 8 drives the bidirectional screw 7 to rotate, causing the two sets of bearing blocks 5 to move relative to each other, thus achieving clamping of materials of different sizes. The rubber pads 14 installed on the inner wall of the long side of the L-shaped clamping plate 13 increase clamping friction and also act as a buffer, preventing damage to the material. Furthermore, the guide strips 9 and guide grooves 10 ensure the stability of the movement of the bearing blocks 5, and multiple sets of bearing blocks 5 provide stable support for the L-shaped clamping plate 13. This design enables the clamping assembly to stably and accurately clamp materials of various shapes and sizes, whether square, round, or other irregularly shaped materials, achieving reliable clamping and fixation, ensuring the stability of the material during the testing process, and improving the reliability of the test results. The construction material safety testing equipment of this utility model has a reasonable overall structural design, with tight cooperation between all components, convenient operation, and low maintenance costs. Components such as the loading plate 1, support column 2, and support frame 3 provide a stable support platform for the testing equipment, ensuring its stability during operation. The reasonable layout of the adjustment and clamping components makes the equipment simple and easy to understand, allowing operators to quickly learn how to use it. Compared with existing technologies, this utility model avoids complex operating procedures and cumbersome maintenance steps. For example, when adjusting the detection position, multi-directional movement adjustment can be achieved simply by rotating the first screw 25 and the second screw 17; when clamping materials, the clamping operation can be easily completed by rotating the first handwheel 8. This simple and easy-to-use design not only reduces the difficulty of operation but also reduces equipment failures caused by improper operation, thereby reducing equipment maintenance costs.At the same time, a reasonable structural design also facilitates the daily maintenance and repair of the equipment, improving its service life and economic benefits.

[0028] Furthermore, in this example, such as Figure 1 , Figure 2 and Figure 5As shown, the adjustment and detection assembly includes a first mounting bracket 4. A first sliding groove is formed on the lower end face of the first mounting bracket 4. A first sliding block is slidably installed in the first sliding groove. A second mounting bracket 15 is installed at the other end of the first sliding block. The second mounting bracket 15 and the first mounting bracket 4 are perpendicular to each other. A first screw 25 is installed vertically on the top sidewall of the two support brackets 3 at the position of the second mounting bracket 15. One end of the first screw 25 penetrates and protrudes from the sidewall of the support bracket 3, and a third handwheel 19 is provided at the end of the first screw 25. The other end of the second mounting bracket 15 is engaged and rotatably mounted on the sidewall of the support bracket 3, and the middle of the first screw 25... A second sliding block 17 is vertically inserted through both side walls of the second mounting bracket 15, and a second sliding groove is formed on the lower end face of the second mounting bracket 15. A second sliding block 17 is slidably installed in the second sliding groove, and a connecting block 20 is installed at the other end of the second sliding block. A set of mounting blocks 16 are respectively installed at both ends of the lower end face of the second mounting bracket 15, and a second screw 17 is installed on both sets of mounting blocks 16. One end of the second screw 17 penetrates through and protrudes from the side wall of the mounting block 16, and a second handwheel 18 is installed at the end of the second screw 17. The other end of the second screw 17 is engaged and rotatably installed on the side wall of the other set of mounting blocks 16, and the middle part of the second screw 17 vertically penetrates through the connecting block 20. Connecting plates 21 are installed on the bottom of connecting blocks 20 at both ends of the connecting block 20. Two sets of hydraulic cylinders 22 are installed on the bottom of the connecting plates 21. Extrusion plates 23 are installed at the output ends of the hydraulic cylinders 22. A placement groove is opened in the middle of the bottom end of the extrusion plate 23. A pressure sensor 24 is installed inside the placement groove. A first circular hole with the same diameter as the first screw 25 is opened on the support frame 3 at the position where the first screw 25 passes through. The first screw 25 is engaged and rotated in the first circular hole. A circular groove with the same diameter as the first screw 25 is opened on the side wall of the support frame 3 at the other end of the first screw 25. The side wall of the second mounting bracket 15 is... A first threaded hole, matching the first screw 25, is provided at the position of the first screw 25. A second circular hole, with the same diameter as the second screw 17, is provided on a set of mounting blocks 16 at the position where the second screw 17 passes through, and the second screw 17 is engaged and rotatably installed in the second circular hole. A circular groove, with the same diameter as the mounting block 16, is provided on the side wall of another set of mounting blocks 16 at the position of the second screw 17. A second threaded hole, matching the second screw 17, is provided on the side wall of the connecting block 20 at the position of the second screw 17. The adjustment and detection assembly achieves multi-dimensional position adjustment through a mechanical transmission structure to accurately position the detection component. Specifically, a first sliding block is slidably installed in a first sliding groove on the lower end face of the first mounting bracket 4, and the other end of the first sliding block is connected to the second mounting bracket 15.Two support frames 3 are vertically mounted on their top sidewalls, corresponding to the positions of the second mounting frame 15. One end of the first screw 25 passes through and protrudes from the sidewall of the support frame 3 and is equipped with a third handwheel 19. The other end is engaged and rotatably mounted on the sidewall of the support frame 3. The middle portion vertically passes through both sidewalls of the second mounting frame 15. Rotating the third handwheel 19 causes the first screw 25 to rotate. Because the first screw 25 engages with the first threaded hole on the sidewall of the second mounting frame 15, the second mounting frame 15 moves horizontally. A second sliding groove is formed on the lower end face of the second mounting frame 15, and a second sliding block is slidably mounted inside. The other end of the second sliding block is connected to a connecting block 20. Mounting blocks 16 are mounted at both ends of the lower end face of the second mounting frame 15. Two sets of mounting blocks 16 are jointly mounted with a second screw 17. One end of the second screw 17 passes through and protrudes from the sidewall of the mounting block 16 and is equipped with a second handwheel 18. The other end is engaged and rotatably mounted on the sidewall of another set of mounting blocks 16. The middle portion vertically passes through both sidewalls of the connecting block 20. Rotating the second handwheel 18 drives the second screw 17 to rotate. Since the second screw 17 engages with the second threaded hole on the side wall of the connecting block 20, the connecting block 20 moves horizontally in the second mounting bracket 15. Through the coordinated action of the first screw 25 and the second screw 17, the detection component can be flexibly adjusted in multiple directions and accurately moved to the appropriate position on the material to be tested.

[0029] Furthermore, in this example, such as Figure 1 , Figure 3 and Figure 4As shown, the clamping assembly includes two sets of mounting seats 6, which are respectively installed at opposite ends of the upper surface of the loading tray 1. A set of guide bars 9 are installed at both ends of the top of the opposite sidewalls of the two sets of mounting seats 6. Guide grooves 10 are formed on the inner walls of both sets of guide bars 9. A bidirectional screw 7 is installed on both sets of mounting seats 6. One end of the bidirectional screw 7 is engaged and rotatably mounted on the sidewall of one set of mounting seats 6, while the other end of the bidirectional screw 7 protrudes through the sidewall of the mounting seat 6. A first handwheel 8 is installed at the end of the bidirectional screw 7. A set of loading sliding blocks 12 are respectively driven and installed at both ends of the bidirectional screw 7. An L-shaped clamping plate 13 is installed on the top of the loading sliding block 12, and a rubber pad 14 is installed on the inner wall of the long side of the L-shaped clamping plate 13. Multiple sets of support rods 11 are evenly installed on the lower end face of the guide bars 9. The other end of each of the 11 is mounted on the loading plate 1. Multiple sets of bearing blocks 5 are evenly arrayed on the upper surface of the loading plate 1. The upper surface of each set of bearing blocks 5 is at the same height as the upper surface of the short side of the L-shaped clamping plate 13. The two end side walls of the two sets of loading sliding blocks 12 are provided with through holes of the same diameter as the bidirectional screw 7 at the corresponding positions. Limiting cylinders are installed on the inner walls of the through holes. The other ends of the limiting cylinders are slidably mounted in the threaded grooves of the bidirectional screw 7. Guide rods are installed on the two end side walls of the loading sliding blocks 12 at the corresponding positions of the guide grooves 10. The other ends of the guide rods are slidably mounted in the guide grooves 10. The diameter of the guide rods is the same as the height of the guide grooves 10. Two sets of mounting seats 6 are symmetrically mounted on opposite ends of the upper surface of the loading plate 1, providing a stable mounting base for the entire clamping assembly. A bidirectional screw 7 is mounted on both sets of mounting bases 6. One end of the bidirectional screw 7 is engaged and rotatably mounted on the side wall of one set of mounting bases 6, while the other end protrudes through the side wall of the mounting base 6 and is fitted with a first handwheel 8. When the material to be tested needs to be clamped, the operator rotates the first handwheel 8, which drives the bidirectional screw 7 to rotate. A set of loading sliding blocks 12 are driven and mounted at each end of the bidirectional screw 7. These two sets of loading sliding blocks 12 are key components for performing the clamping action. Each end of the loading sliding block 12 has a through-hole with the same diameter as the bidirectional screw 7 at the corresponding position on its side wall. A limiting cylinder is mounted on the inner wall of the through-hole, and the other end of the limiting cylinder is slidably mounted in the threaded groove of the bidirectional screw 7. Due to the engagement between the limiting cylinder and the threaded groove of the bidirectional screw 7, the limiting cylinder slides along the threaded groove when the bidirectional screw 7 rotates. Because the threads at both ends of the bidirectional screw 7 are in opposite directions, the limiting cylinders at both ends will drive the two sets of loading sliding blocks 12 to move relative to each other along the axial direction of the bidirectional screw 7, that is, to move closer to each other or further away from each other. An L-shaped clamping plate 13 is installed on the top of the loading sliding block 12, and the L-shaped clamping plate 13 will also move with the relative movement of the loading sliding block 12.When the two sets of loading sliding blocks 12 approach each other, the L-shaped clamping plates 13 also approach each other, thus clamping the material to be tested. After the test is completed, the first handwheel 8 is rotated in the opposite direction, the double-acting screw 7 rotates in the opposite direction, the two sets of loading sliding blocks 12 move away from each other, and the L-shaped clamping plates 13 release the material. A set of guide strips 9 are installed at both ends of the top of the opposite side walls of the two sets of mounting bases 6, and guide grooves 10 are opened on the inner walls of both sets of guide strips 9. Guide rods are installed on the side walls of the loading sliding blocks 12 at the positions corresponding to the guide grooves 10. The other end of the guide rod is slidably installed in the guide groove 10, and the diameter of the guide rod is the same as the height of the guide groove 10. This design ensures that the guide rod always slides in the guide groove 10 during the movement of the loading sliding block 12, providing precise guidance for the movement of the loading sliding block 12. When the bidirectional screw 7 rotates, driving the loading sliding block 12 to move, the sliding of the guide rod within the guide groove 10 restricts the movement direction of the loading sliding block 12, ensuring it can only move along the direction of the guide groove 10. This prevents the loading sliding block 12 from shaking, shifting, or rotating during movement, thus ensuring the stability of the L-shaped clamping plate 13's clamping action and making the clamping more precise and reliable. Simultaneously, multiple sets of support rods 11 are evenly installed on the lower end face of the guide bar 9, with the other end of each support rod 11 mounted on the loading plate 1. The support rods 11 support the guide bar 9, enhancing its stability and further ensuring the reliability of the entire guide structure, providing a strong guarantee for the stable movement of the loading sliding block 12. Rubber pads 14 are installed on the inner wall of the long side of the L-shaped clamping plate 13. When the L-shaped clamping plate 13 clamps the material to be tested, the rubber pads 14 increase the friction between the rubber pads and the material. This is because the surface of the rubber pads 14 has a certain roughness, generating greater friction when in contact with the material surface, making the clamping more secure and preventing the material from slipping during testing. In addition, the rubber pad 14 also has a cushioning function. During clamping, the rubber pad 14 can absorb part of the clamping force, preventing excessive clamping force from damaging the material, and also reducing clamping instability caused by uneven material surfaces. Multiple sets of bearing blocks 5 are evenly arrayed on the upper surface of the loading tray 1, with the upper surface of each set of bearing blocks 5 at the same height as the upper surface of the short side of the L-shaped clamping plate 13. The bearing blocks 5 provide a stable placement platform for the material to be tested, ensuring stability when the material is placed on them. During clamping, the bearing blocks 5 and the L-shaped clamping plate 13 work together to ensure the stability of the material during testing, further improving the reliability of the test results.
