Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineering quality testing technology, and in particular to a verticality testing device for engineering quality testing. Background Technology
[0002] Engineering quality testing technology is a technique that tests engineering materials, physical structures, and their functionality according to regulations and standards to determine their quality characteristics. This includes designing verticality testing devices for engineering quality testing, used to accurately detect the verticality of building components, ensuring structural safety and subsequent construction accuracy.
[0003] Under current conditions, a verticality testing device for engineering quality inspection, as disclosed in CN217738261U, is commonly used. This device includes a frame, a base, and an adjustment mechanism. The frame is mounted on the adjustment mechanism, which in turn is mounted on the base. Rotating the handle drives the connecting shaft to rotate, allowing the movable seat to move along the guide rod. However, this device's frame and base are connected via the adjustment mechanism, resulting in a relatively complex structure that relies on sliding fit. After prolonged use, wear can increase the clearance between the parts. When the frame or adjustment mechanism wears down, it is difficult to replace or repair quickly, leading to the scrapping of the entire device or increased maintenance costs. Furthermore, this device only uses a traditional plumb line for unidirectional verticality testing. In actual engineering projects, it is often necessary to simultaneously test the verticality of walls and corners. This single-function device requires additional specialized tools for auxiliary testing, increasing equipment cost and operational complexity. Moreover, manual reading and judgment are prone to introducing errors, reducing the accuracy and versatility of the test results. Utility Model Content
[0004] The purpose of this invention is to solve the problem of inconvenient maintenance and replacement of existing verticality testing devices after wear, and to propose a verticality testing device for engineering quality testing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A verticality testing device for engineering quality inspection includes a support base, on which a mounting frame is fixedly installed by a threaded bolt. A support rod is placed inside the mounting frame, and a limiting structure for longitudinally limiting the support rod is provided on the mounting frame. A detector for detecting the verticality of a right-angle wall is movably installed on the support base.
[0007] Preferably, the mounting bracket has a limiting groove for limiting the support rod, and a limiting block extending into the support rod is fixedly installed in the limiting groove.
[0008] Preferably, the limiting structure includes a fixing frame fixedly installed on the support rod, and limiting rods for limiting the fixing frame are installed on both sides of the mounting frame by pins;
[0009] Two movable blocks are slidably sleeved inside the fixed frame, and a spring is welded between the movable blocks and the fixed frame. A T-shaped block extending out of the fixed frame and two connecting blocks are fixedly installed on the movable blocks. A contact frame that moves against the limiting rod is fixedly installed on the two connecting blocks, and a contact block that penetrates the limiting rod and extends into the fixed frame is fixedly installed on the contact frame.
[0010] The support rod is slidably fitted with a threaded ring that moves against the T-block.
[0011] Preferably, the limiting rod has an L-shaped structure, and the support rod has a threaded groove that matches the threaded ring frame.
[0012] Preferably, the support rod is provided with two movable frames by locking components. The locking components include a positioning rod placed inside the support rod and positioning the movable frames. A guide rod is slidably sleeved on the movable frames, and a limiting block that passes through the support rod and limits the positioning rod is fixedly installed on the guide rod. A spring that cooperates with the guide rod is welded between the limiting block and the movable frames.
[0013] The support rod has evenly distributed positioning holes that correspond to the positioning rods.
[0014] Preferably, the detector includes a detection frame fixedly installed on a movable frame, and a rotating frame is installed on the detection frame by a pin. A laser plumb bob and a laser receiver one for detecting the verticality of the wall are respectively provided on the two detection frames. A laser line projector for detecting the verticality of the wall corner is fixedly installed on the detection frame, and a laser receiver two that cooperates with the laser line projector is installed on the rotating frame by a pin.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] 1. This utility model places the support rod in the limiting groove of the mounting frame, the limiting block initially limits the support rod, pulls the two limiting rods to limit the fixed frame, and rotates the threaded ring frame to move it downward. The threaded ring frame contacts and presses the T-block, the T-block drives the moving block to press the spring, and the moving block drives the abutment block to extend into the fixed frame through the connecting block and the abutment frame, thus realizing the stable locking of the limiting rod. This makes it convenient for workers to install, disassemble and replace the support rod. When the mounting frame is worn, it can be quickly replaced. It is also convenient for overall transportation and storage.
[0017] 2. This utility model allows for rapid adjustment of the height of the moving frame by pulling the guide rod, which in turn causes the limiting block to press against the second spring. The limiting block is then disconnected from the positioning rod. The positioning rod is removed, the moving frame is adjusted to the specified height, the positioning rod is inserted into the corresponding positioning hole, and the guide rod is released. This helps to improve the efficiency and convenience of height adjustment during the testing process, enabling the equipment to flexibly adapt to different on-site testing needs.
[0018] 3. This utility model involves placing two testing frames close to the wall. The laser plumb bob emits a vertical laser downwards, and the first laser receiver detects the verticality of the wall by receiving the laser. When it is necessary to detect the verticality of the corner, the rotating frame is pulled and rotated 90°, bringing the testing frame and the rotating frame close to the corner. The laser projector emits a laser in the horizontal direction of the vertical testing frame, and the second laser receiver detects the verticality of the corner by receiving the laser. This allows for quick switching between two working modes: wall verticality detection and corner verticality detection. There is no need to carry or change multiple special tools, which helps to improve the versatility of the equipment and the efficiency of engineering applications. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0026] Reference Figures 1-5 A verticality testing device for engineering quality inspection includes a support base 1, and a mounting frame 2 is fixedly installed on the support base 1 by threaded bolts. A support rod 3 is placed inside the mounting frame 2, and a controller is installed on the support rod 3. The mounting frame 2 is provided with a limiting structure for longitudinally limiting the support rod 3. The limiting structure realizes stable limiting and locking of the support rod 3, which facilitates the installation, disassembly and replacement of the support rod 3 by the staff, and also facilitates quick replacement when the mounting frame 2 is worn and overall transportation and storage.
[0027] The support base 1 is equipped with a detector for detecting the verticality of right-angle walls. The detector can be flexibly adjusted in position according to the detection requirements to adapt to different detection scenarios. The detector can detect the verticality of the wall surface and the verticality of the corner, and quickly switch between the two detection modes without the need to carry and replace multiple special tools, thereby improving the versatility of the equipment and the efficiency of engineering applications.
[0028] The mounting bracket 2 has a limiting groove for limiting the support rod 3, and a limiting block 4 extending into the support rod 3 is fixedly installed in the limiting groove. The size of the limiting groove matches the outer diameter of the support rod 3 to ensure that the support rod 3 is accurately placed. The limiting block 4 is made of wear-resistant alloy material and fits tightly against the inner wall of the support rod 3 to initially limit the support rod 3.
[0029] The limiting structure includes a fixed frame 5 fixedly installed on the support rod 3, and limiting rods 6 that limit the fixed frame 5 are installed on both sides of the mounting frame 2.
[0030] Two movable blocks 23 are slidably sleeved inside the fixed frame 5, and a spring 7 is welded between the movable blocks 23 and the fixed frame 5. A T-shaped block 8 extending out of the fixed frame 5 and two connecting blocks 10 are fixedly installed on the movable blocks 23. The T-shaped block 8 increases the contact area with the threaded ring frame 9 to ensure effective transmission of force. The fixed frame 5 is provided with guide holes to guide the connecting blocks 10 and prevent the connecting blocks 10 from shifting during movement.
[0031] Two connecting blocks 10 are fixedly installed with abutting frames 11 that move against the limiting rod 6, and abutting blocks 12 that pass through the limiting rod 6 and extend into the fixed frame 5 are fixedly installed on the abutting frames 11.
[0032] A threaded ring 9 is slidably sleeved on the support rod 3 and moves against the T-block 8. The inner wall of the threaded ring 9 is provided with an internal thread that matches the threaded groove of the support rod 3. When the threaded ring 9 is rotated, it can move up and down along the threaded groove of the support rod 3, thereby applying pressure to the T-block 8.
[0033] The limiting rod 6 has an L-shaped structure, and the support rod 3 has a threaded groove that matches the threaded ring frame 9.
[0034] Two movable frames 13 are provided on the support rod 3 by means of locking components. The locking components realize the positioning and height adjustment locking of the movable frames 13, and the height of the movable frames 13 can be quickly adjusted, which helps to improve the efficiency and convenience of height adjustment during testing and adapt to different on-site testing needs. The locking components include a positioning rod 24 placed inside the support rod 3 to position the movable frames 13.
[0035] A guide rod 16 is slidably sleeved on the movable frame 13, and a limiting block 17 that passes through the support rod 3 and limits the positioning rod 24 is fixedly installed on the guide rod 16. A second spring 18 that cooperates with the guide rod 16 is welded between the limiting block 17 and the movable frame 13. The second spring 18 provides a continuous elastic force to the limiting block 17 to ensure the stability of the positioning rod 24.
[0036] The support rod 3 has evenly distributed positioning holes that correspond to the positioning rod 24. The spacing of the positioning holes is set according to the actual testing requirements so as to accurately adjust the height of the moving frame 13.
[0037] The detector includes a detection frame 14 fixedly installed on a movable frame 13, and a rotating frame 15 is mounted on the detection frame 14 with a pin. The detection frame 14 has a storage slot for storing the rotating frame 15, which facilitates storage and protection of the rotating frame 15. The two detection frames 14 are respectively equipped with a laser plumb bob 19 for detecting the verticality of the wall and a laser receiver 20. A laser line projector 21 for detecting the verticality of the wall corner is fixedly installed on the detection frame 14. A laser receiver 22 that cooperates with the laser line projector 21 is mounted on the rotating frame 15 with a pin.
[0038] It should be noted that the specific models and specifications of the controller, laser plumb bob 19, laser receiver 1 20, laser line projector 21, and laser receiver 22 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation methods adopt existing technology in this field, so they will not be elaborated here.
[0039] The functional principle of this utility model can be explained through the following operation methods:
[0040] The support rod 3 is placed in the limiting groove of the mounting frame 2. The limiting block 4 in the mounting frame 2 initially limits the support rod 3. The limiting rod 6 installed on the pins on both sides of the mounting frame 2 is pulled to limit the fixed frame 5. The threaded ring frame 9 is rotated so that the threaded ring frame 9 moves downward along the threaded groove. The threaded ring frame 9 contacts the T-block 8 and applies pressure to it. The T-block 8 drives the moving block 23 to apply pressure to the spring 7. The moving block 23 drives the abutment frame 11 to move through the two connecting blocks 10 fixedly installed on it. The abutment frame 11 drives the abutment block 12 fixedly installed on it to pass through the limiting rod 6 and extend into the fixed frame 5, so as to achieve a stable lock on the limiting rod 6 and complete the installation of the support rod 3.
[0041] When the height of the movable frame 13 needs to be adjusted, pull the guide rod 16. The guide rod 16 drives the limiting block 17 to press the spring 18. The limiting block 17 is disconnected from the positioning rod 24 placed in the support rod 3. Take out the positioning rod 24, adjust the movable frame 13 to the specified height, align the positioning rod 24 with the corresponding positioning hole on the support rod 3, release the guide rod 16, and the spring 18 resets, causing the limiting block 17 to pass through the support rod 3 and limit the positioning rod 24, thus completing the height adjustment of the movable frame 13.
[0042] When performing wall verticality testing, the testing frame 14 is placed close to the wall. The controller sends a start command to the laser plumb bob 19 and the laser receiver 20. The laser plumb bob 19 emits a vertical laser downwards, and the laser receiver 20 detects the wall verticality by receiving the laser.
[0043] When switching to corner verticality detection, pull the rotating frame 15 mounted on the inner pin of the detection frame 14 to rotate the rotating frame 15 90° around the pin. Place the detection frame 14 and the rotating frame 15 close to the corner. The controller sends a start command to the laser projector 21 and the laser receiver 22. The laser projector 21 emits a laser in the horizontal direction of the vertical detection frame 14, and the laser receiver 22 detects the corner verticality by receiving the laser.
[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
