Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a safety detector for construction materials. Background Technology

[0002] In construction projects, construction materials are an essential part. Before use, construction materials need to be tested for quality and safety.

[0003] Patent publication number CN216117049U discloses a safety testing device for construction materials, including a support platform. A movable plate is mounted on the top of the support platform, and extension plates are fixedly connected to both ends of the lower surface of the movable plate. Limiting sliders are fixedly connected to the bottom of the two extension plates on their opposite sides. Limiting grooves are formed on the inner walls of both sides of the upper end of the support platform. In use, the construction material is first placed between the two mounting plates, and then a hydraulic cylinder drives a pressure plate to move downwards to apply pressure to the construction material. This allows for safety testing of the construction material. When multiple points on the top of the construction material need to be tested, the left and right positions of the hydraulic cylinder and the pressure plate are adjusted to perform the tests on multiple points on the top of the construction material.

[0004] However, the aforementioned testing equipment is limited in its ability to inspect the sides of engineering materials, has a limited detection range, cannot perform multi-directional testing of engineering materials, and has low data accuracy, leading to misjudgments of the safety of engineering materials. Therefore, we are now developing a construction engineering material safety detector capable of multi-directional testing of engineering materials. Summary of the Invention

[0005] To overcome the shortcomings of existing testing equipment, which is difficult to inspect the sides of engineering materials and has a limited detection range, thus failing to achieve multi-directional testing of engineering materials, this invention provides a construction engineering material safety detector capable of multi-directional testing of engineering materials.

[0006] A construction material safety detector includes a detection box and a detector. The detector is installed through the upper part of the detection box, and the lower part of the detector is a telescopic part with a built-in pressure sensor. The detector is electrically connected to an external display screen. The detector also includes a clamping assembly, a pushing mechanism, and a locking mechanism. The detection box is equipped with a clamping assembly for clamping the construction material, a pushing mechanism for pushing the construction material backward, and a locking mechanism for limiting the clamping component. By clamping the construction material with the clamping assembly, pushing the construction material with the pushing mechanism, rotating the construction material with the clamping component, and limiting the clamping component, the position of the construction material can be changed, and multi-directional detection can be performed.

[0007] As an improvement to the above solution, the clamping assembly includes a clamping element, a slider, a limiting rod, and a clamping spring. Two arc-shaped holes are opened on both the left and right sides of the detection box, and sliders are slidably connected in each arc-shaped hole. A clamping element is slidably connected between the two sliders on the left side, and a clamping element is also slidably connected between the two sliders on the right side. The clamping elements are rotatably connected to the detection box. Engineering materials are placed between the two clamping elements. Clamping springs are connected between the front and rear sides of the clamping elements and the inner side of the sliders. The clamping springs are all wound around the clamping elements. Limiting rods are slidably connected to the left and right sides of the front of the detection box, and the rear of the limiting rods abuts against the lower front of the clamping elements.

[0008] As an improvement to the above solution, the pushing mechanism includes a cylinder and a pushing block. The cylinder is connected to the front side of the bottom wall of the detection box, and the pushing block is connected to the rear side of the cylinder extension rod. The pushing block is flush with the engineering material.

[0009] As an improvement to the above solution, the positioning mechanism includes a positioning component, a return spring, and a fixing component. Fixing components are connected to the upper left and right sides of the front of the detection box. Positioning components for limiting the clamping component are slidably connected to the fixing components. The upper part of the positioning component is slidably connected to the detection box. The lower rear side of the positioning component is an arc surface. A return spring is connected between the positioning component and the upper side of the fixing component. The return spring is wound around the positioning component.

[0010] As an improvement to the above solution, an unlocking mechanism is also included to push the clamping member outward and unlock the engineering material. The unlocking mechanism includes a connecting plate and a wedge block. The connecting plate is connected to the cylinder extension rod, and the wedge blocks are connected to the left and right sides of the rear of the connecting plate. The cylinder extension rod drives the wedge block to move backward through the connecting plate. The backward movement of the wedge block pushes the clamping member outward and unlocks the engineering material.

[0011] As an improvement to the above solution, a blocking mechanism is also included to block the rotated engineering material. The blocking mechanism includes a blocking block, a compression spring, guide wheels, and a pull rope. A movable plate is connected to the telescopic part of the detector. The blocking block is slidably connected to the rear side of the bottom wall inside the detection box. A compression spring is connected between the front side of the blocking block and the detection box. The compression spring is wound around the front part of the blocking block. Guide wheels are installed on both the left and right sides of the front part of the bottom wall inside the detection box. Two guide wheels are also longitudinally arranged on both the left and right sides of the top wall inside the detector. Pull ropes are connected to both the left and right sides of the front part of the blocking block. The pull ropes pass around the guide wheels, and the upper rear side of the pull ropes is connected to the movable plate. The movable plate moves down to pull the pull ropes, and the pull ropes pull the blocking block forward to the underside of the rotated engineering material to block the engineering material.

[0012] As an improvement to the above scheme, a calibration mechanism for calibrating the rotated engineering material is also included. The calibration mechanism includes a calibration element and a calibration spring. The calibration element is slidably connected to the stop block, and the calibration element is connected to the stop block by a calibration spring.

[0013] As an improvement to the above solution, a driving mechanism for moving the locking component upward is also included. The driving mechanism includes a moving block and a torsion spring. The moving block is rotatably connected to the inner side of the locking component. Torsion springs are connected between the front and rear sides of the moving block and the locking component. The torsion springs are all wound around the moving block. When the moving plate moves upward, it drives the locking component to move upward through the moving block, thereby unlocking the clamping component.

[0014] Beneficial effects: 1. This invention can perform multi-dimensional testing on engineering materials, thereby achieving high testing accuracy and avoiding misjudgments of the safety of engineering materials.

[0015] 2. The present invention utilizes a locking component to limit the rotation of the clamping component, preventing the clamping component from reversing and improving the stability of the clamping component.

[0016] 3. By moving the wedge block backward, the clamping member can be squeezed outward. When the engineering material moves backward, the side of the engineering material will not rub against the clamping member, thereby reducing the loss of the engineering material and improving its integrity.

[0017] 4. By moving the stop block forward, the present invention can support the rotated engineering material, prevent the engineering material from sliding down during the testing process, improve the stability of the rotated engineering material, and make the testing effect better.

[0018] 5. By moving the calibration component forward, the present invention can align and calibrate the rotated engineering material, so that the side of the engineering material is completely perpendicular to the bottom of the detector telescopic part, which is beneficial for people to inspect the side of the engineering material.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] A safety detector for construction materials, such as Figure 1 , Figure 2 and Figure 3As shown, the device includes a detection box 1, a detector 2, a clamping assembly, a pushing mechanism 5, and a locking mechanism 6. The detector 2 is installed through the upper part of the detection box 1, and the lower part of the detector 2 is a telescopic part. The telescopic part of the detector 2 is equipped with a pressure sensor. The detector 2 is electrically connected to an external display screen. The detection box 1 is equipped with a clamping assembly that can clamp the engineering material. The detection box 1 is equipped with a pushing mechanism 5 that can push the engineering material backward. The detection box 1 is equipped with a locking mechanism 6 that can limit the clamping part 3.

[0036] like Figure 1 and Figure 2 As shown, the clamping assembly includes clamping members 3, sliders 31, limiting rods 32, and clamping springs 4. Two arc-shaped holes are opened on both the left and right sides of the detection box 1, and sliders 31 are slidably connected to each arc-shaped hole. There are two clamping members 3, which are slidably connected between the two sliders 31 on the left and the two sliders 31 on the right, respectively. The clamping members 3 are rotatably connected to the detection box 1. The clamping members 3 can clamp the engineering materials, which are placed between the two clamping members 3. Clamping springs 4 are connected between the front and rear sides of the clamping members 3 and the inner sides of the sliders 31, and the clamping springs 4 are wound around the clamping members 3. There are two limiting rods 32, which are slidably connected to the front left and right sides of the detection box 1, respectively. The rear of each limiting rod 32 abuts against the lower front part of the clamping member 3.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, the pushing mechanism 5 includes a cylinder 51 and a pushing block 52. The cylinder 51 is bolted to the front side of the bottom wall of the test box 1, and the pushing block 52 is connected to the rear side of the telescopic rod of the cylinder 51. The pushing block 52 is flush with the engineering material.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the positioning mechanism 6 includes a positioning component 61, a return spring 62, and a fixing component 63. There are two fixing components 63, which are welded to the upper left and right sides of the front of the detection box 1, respectively. There are two positioning components 61, which are slidably connected to the fixing components 63. The upper part of the positioning component 61 is slidably connected to the detection box 1. The lower rear side of the positioning component 61 is an arc surface. The positioning component 61 can limit the clamping component 3. A return spring 62 is connected between the upper side of the positioning component 61 and the fixing component 63. The return spring 62 is wound around the positioning component 61.

[0039] When safety testing of engineering materials is required, this detector 2 can be used. Initially, the engineering material is placed between two clamping parts 3. First, the detector 2 is turned on. The operation of the detector 2 drives the telescopic part of the detector 2 to extend. The extension of the telescopic part of the detector 2 causes the pressure sensor to move downward. When the pressure sensor moves downward and contacts the top middle of the engineering material, the pressure sensor compresses the engineering material and detects the real-time pressure value borne by the engineering material. At this time, people can watch the pressure value borne by the engineering material on the external display screen. If the engineering material reaches the standard pressure and is not damaged, it means that the engineering material is highly safe and qualified. If the engineering material reaches the standard pressure but shows signs of damage, it means that... The engineering material has low safety and is substandard. Therefore, a safety test can be performed on the top center of the engineering material. Then, the telescopic part of detector 2 is controlled to retract. This retraction causes the pressure sensor to move upwards away from the engineering material. Next, cylinder 51 is activated, causing its telescopic rod to extend. This extension causes the push block 52 to move backwards, pushing the engineering material backwards until the front top of the material is below the telescopic part of detector 2. Then, the telescopic part of detector 2 is controlled to move the pressure sensor downwards to detect the front top of the engineering material. This allows for detection of multiple locations on the top of the engineering material. After the top of the material is inspected, the control cylinder 51 retracts, causing the push block 52 to move forward. When the side of the material needs to be inspected, the limit rod 32 is moved forward to separate it from the clamping member 3. Then the clamping member 3 is rotated. Since the clamping member 3 has clamped the material, it also causes the material to rotate, so that the side of the material is below the telescopic part of the detector 2. The clamping member 3 also drives the slider 31 to slide along the arc-shaped hole on the detection box 1. When the clamping member 3 rotates and contacts the arc surface on the lower side of the locking member 61, the clamping member 3 will press the locking member 61 upward, and the return spring 62 will be stretched. When the arc surface separates, under the action of the return spring 62, the locking member 61 moves downward to reset. At this time, the locking member 61 will clamp the clamping member 3 to limit it, preventing the clamping member 3 from rotating in the opposite direction, thereby improving the stability of the clamping member 3. Then, the telescopic part of the detector 2 can be controlled to drive the pressure sensor to move downward to detect the side of the engineering material. This can achieve the effect of multi-directional detection of the engineering material. After the engineering material is detected, the clamping member 3 is rotated clockwise to move away from the locking member 61, and then the locking member 61 is pulled upward. Then the clamping member 3 is reversed to reset. The reverse rotation of the clamping member 3 drives the engineering material to reverse to reset, and the clamping member 3 also drives the slider 31 to slide in the opposite direction along the arc hole on the detection box 1 to reset. Then the limiting rod 32 is pushed backward.The limiting rod 32 is positioned against the lower front part of the clamping member 3, and then the engineering material is removed. Repeating this operation allows for multi-directional inspection of the engineering material, resulting in high inspection accuracy and improved data precision.

[0040] Example 2

[0041] Based on Example 1, such as Figure 1 , Figure 2 and Figure 7 As shown, it also includes an unlocking mechanism 7, which includes a connecting plate 71 and a wedge block 72. The connecting plate 71 is connected to the telescopic rod of the cylinder 51, and the wedge block 72 is connected to both the left and right sides of the rear part of the connecting plate 71.

[0042] When the push block 52 moves the engineering material backward, friction will occur between the side of the engineering material and the clamping member 3. To reduce the wear and tear on the engineering material, the unlocking mechanism 7 can be used. When the cylinder 51 telescopic rod extends, it will also drive the connecting plate 71 and the wedge block 72 to move backward. When the wedge block 72 moves backward and contacts the clamping member 3, it will squeeze the clamping member 3 outward, compressing the clamping spring 4. The lower part of the clamping member 3 continues to support the engineering material, thus preventing the clamping member 3 from clamping the engineering material. Then the push block 52... 2. When the engineering material is moved backward, the push block 52 can smoothly push the engineering material backward, and the side of the engineering material will not rub against the clamping part 3. When the extension rod of the cylinder 51 retracts, it drives the connecting plate 71 and the wedge block 72 to move forward. When the wedge block 72 moves forward and separates from the clamping part 3, the clamping spring 4 rebounds and drives the clamping part 3 to move inward to clamp the engineering material. In summary, the wedge block 72 can be used to squeeze the clamping part 3 outward. Then, when the engineering material moves backward, the side of the engineering material will not rub against the clamping part 3, thereby reducing the loss of the engineering material.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 and Figure 10As shown, it also includes a blocking mechanism 8, which includes a blocking block 81, a compression spring 82, a guide wheel 83, and a pull rope 84. The moving plate 85 is connected to the telescopic part of the detector 2. The blocking block 81 is slidably connected to the rear side of the bottom wall of the detector box 1. The blocking block 81 can block the rotated engineering material. The front side of the blocking block 81 is connected to the detector box 1 by a compression spring 82, which is wound around the front of the blocking block 81. The left and right sides of the front of the bottom wall of the detector box 1 are equipped with guide wheels 83. The left and right sides of the top wall of the detector 2 are also longitudinally arranged with two guide wheels 83. The left and right sides of the front of the blocking block 81 are connected with pull ropes 84. The pull ropes 84 pass around the guide wheels 83, and the upper rear side of the pull ropes 84 is connected to the moving plate 85.

[0044] When the telescopic part of detector 2 extends, it also moves the moving plate 85 downward, pulling the pull rope 84. This causes the pull rope 84 to pull the stop block 81 forward, placing it under the rotated engineering material. The compression spring 82 is compressed, and the stop block 81 then blocks the rotated engineering material. When the side of the engineering material is then inspected, it will not move downward, eliminating the need for the telescopic part of detector 2 to extend excessively, thus facilitating side inspection. When the telescopic part of detector 2 retracts, it moves the moving plate 85 upward, releasing the pull rope 84. The pull rope 84 then stops pulling the stop block 81, and under the action of the compression spring 82, the stop block 81 moves backward to its original position. In summary, after the engineering material rotates, the stop block 81 can be used to block it, preventing it from sliding downward and improving the stability of the rotated material, resulting in better inspection.

[0045] like Figure 1 , Figure 2 , Figure 3 and Figure 11 As shown, it also includes a calibration mechanism 9, which includes a calibration component 91 and a calibration spring 92. The calibration component 91 is slidably connected to the stop block 81. The calibration component 91 can calibrate the rotated engineering material so that the engineering material is completely vertical. The calibration spring 92 is connected between the calibration component 91 and the stop block 81.

[0046] When the engineering material is rotated, it may tilt and become difficult to keep straight. Therefore, the calibration mechanism 9 can be used to calibrate the rotated engineering material. After the engineering material is rotated, the lower part of the rotated engineering material will be in front of the calibration piece 91. At this time, the calibration piece 91 can be pushed forward towards the lower part of the rotated engineering material, and the calibration spring 92 will be stretched. This will straighten the rotated engineering material so that the side of the engineering material is completely perpendicular to the lower part of the telescopic part of the detector 2. After the engineering material is tested, the calibration piece 91 is released. Under the action of the calibration spring 92, the calibration piece 91 moves backward to reset. Repeating the above operation can calibrate the rotated engineering material, which is beneficial for people to test the side of the engineering material.

[0047] like Figure 1 , Figure 2 , Figure 3 , Figure 12 and Figure 13 As shown, it also includes a driving mechanism 10, which includes a moving block 101 and a torsion spring 102. There are two moving blocks 101, which are rotatably connected to the inner side of the locking member 61. Torsion springs 102 are connected between the front and rear sides of the moving block 101 and the locking member 61. The torsion springs 102 are wound around the moving block 101. The moving plate 85 moves upward, which drives the locking member 61 to move upward through the moving block 101, thereby unlocking the clamping member 3.

[0048] When the moving plate 85 moves downward and contacts the moving block 101, due to the large load on the torsion spring 102, the moving plate 85 will also drive the moving block 101 and the locking member 61 to move downward. When the locking member 61 moves to its limit and the moving plate 85 continues to move downward, the moving block 101 will rotate under the pressure of the moving plate 85, and the torsion spring 102 will be twisted. When the moving plate 85 moves downward away from the moving block 101, the moving block 101 will reverse and reset under the action of the torsion spring 102. When the engineering material inspection is completed, the moving plate 85 moves upward and contacts the moving block 101. When contact occurs, the moving plate 85 will also drive the moving block 101 and the locking member 61 to move upward, and the return spring 62 will be stretched. This eliminates the need for manual movement of the locking member 61, thereby speeding up the work process and improving work efficiency. When the locking member 61 moves to its limit, the moving plate 85 will squeeze the moving block 101 to rotate, and the torsion spring 102 will be twisted again. When the moving plate 85 moves upward away from the moving block 101, the torsion spring 102 will drive the moving block 101 to rotate and reset, and the return spring 62 will rebound and drive the locking member 61 and the moving block 101 to move downward and reset.

[0049] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
