Description

Technical Field

[0001] This invention relates to the field of building engineering testing technology, specifically to a deflection testing device for building engineering quality assessment and testing. Background Technology

[0002] Deflection refers to the displacement of the cross-section of a relatively long structural member relative to its theoretical position under a certain load. During construction, deflection testing equipment is typically used to monitor the deflection of buildings to ensure project quality. Deflection observation involves measuring the degree of bending using specific techniques, instruments, or methods. Therefore, it requires the use of deflection testing equipment specifically designed for construction engineering. Areas for improvement in the use of deflection testing equipment include: When using deflection testing equipment, under normal circumstances, the supporting tripod is moved and adjusted on the chassis via the movable adjustment mechanism. The chassis is stably connected to the soil via guide plugs at its bottom, effectively maintaining the stability of the chassis. This allows the supporting tripod to be raised and lowered vertically, enabling the testing unit to be moved and adjusted to the corresponding position of the building. This effectively detects the bending value of the building in the horizontal or vertical directions. When the movable adjustment mechanism is used in conjunction with the supporting tripod for adjustment, lubricant is evenly applied to the guide rods on the chassis to assist in the movement and adjustment. Since the testing unit is located outdoors and measures the building, this is a standard procedure. The air around the construction site contains a large amount of solid particles due to construction. These particles adhere to the outer surface of the guide rod due to airflow. The solid particles and lubricating oil on the guide rod mix together with the sliding adjustment parts to form a grease-coagulated solid substance. As a result, the sliding adjustment parts may jam due to the grease-coagulated solid substance when moving the support tripod on the guide rod. This causes the three legs of the support tripod to shift and not move simultaneously, resulting in the mounting base at the top of the support tripod tilting. This affects the accuracy of the building deflection measurement. Summary of the Invention

Beneficial effects

[0014] This invention discloses a deflection testing device for quality assessment and testing of building engineering projects, which has the following beneficial effects: This invention combines a crossbar, mounting base, swing arm, supporting tripod, auxiliary rotating component, lifting arm, and guide assembly.

[0027] The aforementioned crossbar Q1 and swing bar T5 are used to cooperate with the mounting base E3. Swing bars T5 are installed on both the left and right sides of the mounting base E3. Because the ground at the construction site is relatively uneven, the mounting base E3 is placed on the ground, and the swing bars T5 are moved and adjusted on the crossbar Q1 according to the position of the mounting base E3, thereby adjusting the mounting base E3 to a relatively balanced state and effectively leveling the position of the main body 6.

[0028] Please see Figure 3 The guide assembly Y6 includes a slide groove R11, an insertion hole I15, a movable adjustment component T12, a chassis U14, a guide rod P16, and a positioning block Y13. Three slide grooves R11 are provided, equidistantly arranged in a ring on the chassis U14. An insertion hole I15 is located in the middle of the chassis U14. Three positioning blocks Y13 are inserted into the outside of the insertion hole I15. The end of each positioning block Y13 away from the insertion hole I15 is connected to the guide rod P16. The three guide rods P16 are located inside the corresponding slide grooves R11. Positioning blocks Y13 connect the slide grooves R11 and the guide rods P16. Each of the three guide rods P16 has a movable adjustment component T12, and the two are slidably connected. The chassis U14 is fitted onto the mounting base E3. A lifting rod U7 is inserted into the middle of the insertion hole I15. The movable adjustment component T12 is connected to the support leg of the tripod W2.

[0029] The aforementioned socket I15 is used to cooperate with the movable adjustment component T12. The three movable adjustment components T12 are connected to the three legs of the supporting tripod W2. The lifting rod U7 will be inserted into the socket I15. The other end of the lifting rod U7 is connected to the supporting tripod W2. During the movement and adjustment of the supporting tripod W2 under the action of the movable adjustment component T12, the lifting rod U7 will also be adjusted accordingly, which helps to stabilize the movement of the supporting tripod W2.

[0030] Please see Figure 4The movable adjustment component T12 includes a scraping assembly D21, a restraining limiter F23, a housing L27, a sleeve J25, a connecting plate G22, a triangular pressure member H24, and a fastening interface K26. The scraping assembly D21 is fitted onto the inner wall of the sleeve J25. The sleeve J25 is located in the middle of the housing L27. A connecting plate G22 is provided between the housing L27 and the sleeve J25. The connecting plate G22 is provided with the restraining limiter F23 and the triangular pressure member H24. One side of the triangular pressure member H24 passes through the sleeve J25 and is connected to the scraping assembly D21. The rear end of the triangular pressure member H24 is connected to the restraining limiter F23. Fastening interfaces K26 are installed on both the left and right sides of the housing L27 and are connected to the legs of the supporting tripod W2. The housing L27 is slidably connected to the guide rod P16 through the sleeve J25.

[0031] Please see Figure 4 The triangular pressure member H24 is connected to the side of the scraping component D21 in a triangular structure. Under the action of the restraining and limiting member F23, the triangular pressure member H24 can push the scraping component D21 inward, so that the scraping component D21 can cooperate with the sleeve J25 to make contact with the guide rod P16.

[0032] Please see Figure 5 The scraping assembly D21 includes a slider K31, a contact pad Z33, a counterweight X34, a docking plate L32, a movable groove V36, and a connector C35. The slider K31 and the connector C35 are mounted on the movable groove V36. There are four or more movable grooves V36, which are equidistantly and longitudinally connected to the docking plate L32. The contact pad Z33 is attached to the outer side of the docking plate L32 facing the movable groove V36. Each of the multiple movable grooves V36 has a counterweight X34 inside. The counterweight X34 is connected to the movable groove V36 through the sliders K31 on the left and right sides. The bottom of the counterweight X34 is connected to the connector C35 inside the movable groove V36. The docking plate L32 is fitted and connected to the inner wall of the sleeve J25. The docking plate L32 is connected to the triangular pressure member H24.

[0033] Please see Figure 5 The contact pad Z33 is made of sponge material and has a certain degree of adsorption. When the abutment X34 comes into contact with the guide rod P16, the contact pad Z33 will adhere to it, effectively cooperating with the abutment X34 to adsorb and remove the solid substances of grease and coagulation on the guide rod P16.

[0034] Please see Figure 6The abutment component X34 includes an arc-guiding spring C41, a resilient abutment plate B46, an airbag N42, a rotating wheel W47, an arc-changing support M44, a securing ring Q45, an abutment rod V43, and a linkage spring E48. The arc-guiding spring C41 has two pieces symmetrically arranged on the left and right sides of the abutment rod V43. The lower end of the abutment rod V43 is inserted into the recessed position of the linkage spring E48, and the upper end of the linkage spring E48 is connected to the arc-guiding spring C41. The two pieces of the arc-guiding spring C41... The upper end of the guide spring C41 is in contact with both sides of the inner arc surface of the arc-shaped support M44. A rotating wheel W47 is installed in the middle of the arc-shaped support M44. A tough abutment plate B46 is provided on the outer arc surface of the arc-shaped support M44 and is connected thereto. A fastening ring Q45 is installed at both the left and right ends of the arc-shaped support M44. The fastening ring Q45 is fixedly connected to the slider K31. The linkage spring E48 is located inside the movable groove V36 and its bottom is connected to the connector C35.

[0035] Please see Figure 6 The linkage spring E48 is connected to the lower end of the two guide arc springs C41 in a "Y" shape.

[0036] The aforementioned flexible abutment plate B46 and rotating wheel W47 are used to cooperate with the arc deformation support M44. Multiple flexible abutment plates B46 and rotating wheels W47 are installed on the arc deformation support M44. When the outer shell L27 moves and adjusts on the guide rod P16 under the action of the sleeve J25, the arc deformation support M44 will come into contact with the guide rod P16. After the two are connected, they will generate pressure, causing the arc deformation support M44 to deform and retract inward and extend outward. The rotating wheel W47 in the middle position of the arc deformation support M44 will then come into contact with the guide rod P16, which helps to cooperate with the movement of the outer shell L27. The flexible abutment plate B46 is made of elastic and tough material. Under the action of the arc deformation support M44, it will fit and contact the guide rod P16, which can effectively scrape off the solid substances of grease and coagulation on the guide rod P16. Example

[0037] Please see Figure 1 The present invention provides a technical solution: a deflection detection device for quality appraisal and testing of building engineering, the structure of which includes an operation panel 1, a main body 6, a protective plate 2, a camera 7, a bracket 3, a base 5, and an adjustment device 4. The operation panel 1 is disposed on the base 5, the base 5 is mounted on the adjustment device 4, the base 5 is mounted on the lower end of the main body 6, the main body 6 is provided with the protective plate 2 and the bracket 3, and the camera 7 is installed in the middle of the main body 6. The camera 7 is electrically connected to the operation panel 1.

[0038] Please see Figure 2The adjusting device 4 includes a crossbar Q1, a mounting base E3, a swing rod T5, a supporting tripod W2, an auxiliary rotating component R4, a lifting rod U7, and a guide assembly Y6. Two crossbars Q1 are provided, symmetrically positioned on both sides of the lower end inside the mounting base E3. A swing rod T5 is mounted on each of the two crossbars Q1 and the two are slidably connected. The top of the mounting base E3 is fitted with the guide assembly Y6. The lifting rod U7 is inserted into the middle of the guide assembly Y6, and its upper end is inserted into the supporting tripod W2. The supporting tripod W2 is mounted on the guide assembly Y6 and the two are movably connected. The top of the supporting tripod W2 is mounted with the auxiliary rotating component R4, and the top of the auxiliary rotating component R4 is fitted with the bottom of the base 5.

[0039] The aforementioned crossbar Q1 and swing bar T5 are used to cooperate with the mounting base E3. Swing bars T5 are installed on both the left and right sides of the mounting base E3. Because the ground at the construction site is relatively uneven, the mounting base E3 is placed on the ground, and the swing bars T5 are moved and adjusted on the crossbar Q1 according to the position of the mounting base E3, thereby adjusting the mounting base E3 to a relatively balanced state and effectively leveling the position of the main body 6.

[0040] Please see Figure 3 The guide assembly Y6 includes a slide groove R11, an insertion hole I15, a movable adjustment component T12, a chassis U14, a guide rod P16, and a positioning block Y13. Three slide grooves R11 are provided, equidistantly arranged in a ring on the chassis U14. An insertion hole I15 is located in the middle of the chassis U14. Three positioning blocks Y13 are inserted into the outside of the insertion hole I15. The end of each positioning block Y13 away from the insertion hole I15 is connected to the guide rod P16. The three guide rods P16 are located inside the corresponding slide grooves R11. Positioning blocks Y13 connect the slide grooves R11 and the guide rods P16. Each of the three guide rods P16 has a movable adjustment component T12, and the two are slidably connected. The chassis U14 is fitted onto the mounting base E3. A lifting rod U7 is inserted into the middle of the insertion hole I15. The movable adjustment component T12 is connected to the support leg of the tripod W2.

[0041] The aforementioned socket I15 is used to cooperate with the movable adjustment component T12. The three movable adjustment components T12 are connected to the three legs of the supporting tripod W2. The lifting rod U7 will be inserted into the socket I15. The other end of the lifting rod U7 is connected to the supporting tripod W2. During the movement and adjustment of the supporting tripod W2 under the action of the movable adjustment component T12, the lifting rod U7 will also be adjusted accordingly, which helps to stabilize the movement of the supporting tripod W2.

[0042] Please see Figure 7The auxiliary rotating component R4 includes a fixed plate E51, a sleeve plate Y54, a locking screw I56, a pressing rod T52, a movable cover S59, a mounting plate R53, a movable seat P57, a connecting rod U55, and a swing rotating component A58. The fixed plate E51 and the sleeve plate Y54 are locked together by the locking screw I56. The swing rotating component A58 is installed on the top of the sleeve plate Y54. The swing rotating component A58 is connected to the movable cover S59. The movable cover S59 is positioned on the left and right sides. Movable seats P57 are installed on both sides. A pressing rod T52 is connected through the two movable seats P57. The pressing rod T52 passes through the movable seat P57 and connects to the swing rotating part A58. A mounting plate R53 is installed on the top of the movable cover S59. A connecting rod U55 connects the mounting plate R53 and the fixed plate E51. The bottom of the fixed plate E51 is connected to the top of the supporting tripod W2. The top of the mounting plate R53 is connected to the bottom of the base 5.

[0043] Please see Figure 7 The movable cover S59 is engaged with the swing rotating part A58.

[0044] The aforementioned movable cover S59 is used to cooperate with the mounting plate R53. The mounting plate R53 is installed on the movable cover S59. The movable cover S59 is connected to the swinging rotating member A58 to form a universal joint, so that the movable cover S59 can be stably adjusted to a parallel state with the position of the mounting plate R53 under the action of the swinging rotating member A58.

[0045] The working principle of the above technical solution is explained below: In use, the base 5 at the bottom of the main body 6 is stably installed on the mounting plate R53 at the top of the auxiliary rotating component R4. The fixing plate E51 at the bottom of the auxiliary rotating component R4 is fixedly connected to the top of the supporting tripod W2 at its center. When it is necessary to detect the deflection of the building, the main body 6 is moved to the corresponding position, and the bottom of the mounting base E3 will be placed on the ground of the construction site. Because the ground of the construction site is relatively uneven, swing rods T5 are installed on both the left and right sides of the bottom of the mounting base E3. By moving and adjusting the swing rods T5 on the crossbar Q1 according to the position of the mounting base E3, the mounting base E3 is adjusted to a relatively balanced state, which effectively drives the chassis U14 above it to be leveled. The chassis U14 is adjusted to... Once balanced, the three grooves R11 on the chassis U14 are positioned by positioning blocks Y13 to hold the guide rod P16 in place. A movable adjustment component T12 is mounted on the guide rod P16. Two snap-fit ​​interfaces K26 on the outer shell L27 of the movable adjustment component T12 engage with the three corresponding legs of the supporting tripod W2. The sleeve J25 in the middle of the outer shell L27 engages with the guide rod P16, allowing the outer shell L27 to move parallel to the guide rod P16. A connecting plate G22 is installed between the outer shell L27 and the sleeve J25. A triangular pressing component H24 inside the connecting plate G22 passes through the sleeve J25 and connects to the side of the scraping assembly D21. A restraining limiting component F23 is connected to the rear of the triangular pressing component H24. The restraining component F23 has significant elasticity, effectively working with the triangular pressing component H24 to push the docking plate L32 on the scraping assembly D21 inward. This allows the docking plate L32 to engage with the sleeve J25 and contact the guide rod P16. Multiple movable slots V36 on the docking plate L32 each contain abutting components X34. Under the action of the slider K31 and the connector C35, the abutting components X34 can move stably up and down within the movable slots V36. Under the action of the docking plate L32, the abutting components X34 can engage with the guide rod P16. A contact pad Z33 is attached to the side of the docking plate L32 facing the abutting components X34. The contact pad Z33 has a certain degree of adsorption. When the abutting components X34 contact the guide rod P16... Simultaneously with contact at point 16, contact pad Z33 adheres to it, effectively cooperating with the abutment X34 to absorb and remove the solidified grease on guide rod P16. Multiple flexible abutment plates B46 and rotating wheels W47 are installed on the arc-deformation support M44 of the abutment X34. When the outer shell L27 moves and adjusts on guide rod P16 under the action of sleeve J25, the arc-deformation support M44 contacts guide rod P16. The connection generates pressure, causing the arc-deformation support M44 to deform, retracting inwards and extending outwards. The air bladder N42 at the lower end of the arc-deformation support M44 expands downwards under the pressure of its internal gas, pressing down on the two lower arc-guided spring plates C41.When the arc guide spring C41 is compressed, it will extend and adjust in conjunction with the arc-changing support M44. Simultaneously, the lower end of the arc guide spring C41, connected to the auxiliary rod V43 and the linkage spring E48, will be pressed down. Both will retract inwards under pressure. When the elastic element inside the linkage spring E48 is compressed to a certain limit, it will generate a rebound force, driving the auxiliary rod V43 to push the arc guide spring C41 outwards. The arc guide spring C41 will then pull the arc-changing support M44 outwards, allowing it to attach to the guide rod P16. The rotating wheel W47 is located in the middle of the arc-changing support M44. The rotating force of the wheel W47, which then contacts the guide rod P16, helps the housing L27 move along the guide rod P16. The flexible abutment plate B46, with its triangular structure and made of elastic material, comes into contact with the guide rod P16 under the action of the arc-shaped support M44. This effectively scrapes away any grease or solidified material on the guide rod P16. The abutment X34 and contact pad Z33 work together to clean the grease or solidified material adhering to the guide rod P16, allowing the housing L27 to remain stable under the action of the sleeve J25. After adjusting the tripod W2 to a relatively balanced state, when the tripod W2 is moved to a certain position, the top of the tripod W2 connects with the fixed plate E51 on the auxiliary rotating component R4. When the fixed plate E51 is slightly tilted under the action of the tripod W2, the sleeve Y54 will drive the swing rotating component A58 to move accordingly. The movable cover S59 is connected to the swing rotating component A58 to form a universal joint, allowing the movable cover S59 to rotate under the action of the swing rotating component A58 to stably level the position of the mounting plate R53. The mounting plate R53 is in During adjustment, the connecting rods U55 on both sides extend and retract with the swinging of the fixed plate E51 and the mounting plate R53. Then, the pressing rod T52 extends into the movable cover S59 and abuts against the swinging rotating part A58, effectively limiting the position of the movable cover S59 and effectively adjusting and maintaining the position of the mounting plate R53 in the corresponding position. This allows the main body 6 to maintain balance with the building under its action. Driven by the movable cover S59, the mounting plate R53 can effectively detect and process the bending value of the building in the horizontal or vertical direction, ensuring the accuracy of the building deflection measurement.

[0046] In summary, this invention employs a combination of an operation panel, a main body, a protective plate, a camera, a bracket, a base, and an adjustment device to form a new deflection detection device for building engineering quality assessment and testing. The swing arm moves and adjusts the mounting base along the crossbar according to its position, thereby bringing the mounting base to a relatively balanced state and effectively leveling the main body. The supporting tripod, with its guide assembly, can move up and down to adjust the position of the auxiliary rotating component. This allows the auxiliary rotating component to move the main body up and down through the base to a position corresponding to the building, effectively detecting the bending value of the building in the horizontal or vertical direction.
