Description

Technical Field

[0001] This utility model is a quality testing device for construction engineering supervision and management, belonging to the field of construction engineering quality testing. Background Technology

[0002] Building construction quality testing refers to the activities of testing and determining the quality characteristics of building materials, components, equipment, and the quality and functionality of the building entity, in accordance with relevant national laws, regulations, mandatory engineering construction standards, and design documents. Among these activities, hollowness testing of completed buildings is an important part of building entity quality testing.

[0003] Traditional testing methods involve using a hollow-sounding hammer to locate hollow areas and marking them with a marker. This is not only cumbersome but also results in inconsistent striking force. Too much force may damage the tiles, while too little force will not achieve the desired testing effect, leading to poor testing results. Therefore, it is necessary to design a quality testing device for construction project supervision and management. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quality inspection device for construction engineering supervision and management, so as to solve the problems mentioned in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection device for construction engineering supervision and management, comprising a base, a vertical rail mounted on one end of the top of the base, and a foot controller mounted on the other end of the top of the base. A lifting groove is provided at the center of the interior of the vertical rail, and a lead screw is vertically mounted at the center of the lifting groove. A servo motor is installed in the base below the lead screw, and the output end of the servo motor is connected to the lead screw via a rotating shaft. A matching nut is fitted onto the lead screw, and a mounting bracket is connected to the end of the nut near the foot controller. A hinge seat is connected to the end of the nut away from the foot controller, and a detection component is mounted on the hinge seat. Flip-up stamps are slidably connected to both sides of the top of the mounting bracket, and the ends of the flip-up stamps near the foot controller are connected via connecting rods.

[0006] Furthermore, a storage battery is installed inside the base, and a level is embedded in the center of the top of the base, and ball bearings are evenly distributed on the bottom of the base.

[0007] Furthermore, both sides of the vertical rail away from the foot pedal controller protrude outward to form side plates, and rollers are evenly installed on the side plates away from the foot pedal controller, and the rollers are all vertically arranged.

[0008] Furthermore, through slots are provided on the vertical rails at both ends of the lifting groove, and the two ends of the nut pass through the through slots and are connected to the mounting frame and the hinge seat, respectively.

[0009] Furthermore, the mounting frame includes a U-shaped frame and uprights, and the inner width of the U-shaped frame matches the outer width of the uprights. Uprights are integrally connected to both sides of the U-shaped frame, and each upright has a mounting groove at its top and a compression groove at its bottom. A compression spring is installed in each compression groove. The flip-up stamps are all shaped to match the mounting grooves, and a pressure plate with a shape matching the compression groove is fixed to the bottom of each flip-up stamp. The pressure plate abuts against the end of the compression spring near the foot pedal controller.

[0010] Furthermore, the detection assembly includes a hollow hammer, gears, a rotating rod, a connecting seat, and a torsion spring. The rotating rod passes through the hinge seat and is rotatably connected to the hinge seat. The gears are symmetrically arranged on both sides of the rotating rod. A connecting seat is fixed at the center of the rotating rod, and a hollow hammer is threadedly connected to the top of the connecting seat. A torsion spring is sleeved on the rotating rod inside the connecting seat, and one end of the torsion spring is inserted into the inside of the connecting seat. A stop plate is integrally connected to the bottom of the hinge seat, and the other end of the torsion spring abuts against the inner side of the stop plate.

[0011] Furthermore, toothed plates are evenly spaced on the vertical rails on both sides of the detection component, and the toothed plates mesh with gears. The number of teeth on the toothed plates is one-quarter of the number of teeth on the gears.

[0012] The beneficial effects of this utility model are:

[0013] 1. The device consists of a lead screw, a lead nut, a detection component, and evenly spaced toothed plates. Rotation of the lead screw causes the lead nut to move up and down along the vertical rail, thus moving the detection component up and down. During detection, the detection component moves upward with the lead nut. When the gear contacts the toothed plate, the upward movement of the detection component causes the gear to rotate, which in turn causes the hollow hammer to rotate towards the through groove. The torsion spring is compressed. When the gear moves to the interval between two adjacent toothed plates, the torsion spring resets, causing the hollow hammer to rotate towards the wall, achieving the tapping detection. The gear rotates at a consistent angle each time, meaning the torsion spring experiences consistent force, resulting in consistent tapping force from the hollow hammer upon reset. The lead nut moves up and down along the vertical rail, thus moving the detection component up and down, allowing for hollow detection at different heights. This eliminates the need for manual tapping, reducing the likelihood of omissions and ensuring good performance.

[0014] 2. The device is equipped with a foot pedal controller, flip-up stamps, and connecting rods. During testing, stepping on the foot pedal controller powers on the servo motor, which then starts the test. When a hollow sound is detected by tapping, releasing the foot pedal controller stops the servo motor. Pressing the connecting rod down towards the wall moves the two flip-up stamps closer to the wall, marking the hollow area. The operation is very convenient. Attached Figure Description

Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5This utility model provides a technical solution: it includes a base 1, a vertical rail 4 is installed at one end of the top of the base 1, and a foot controller 3 is provided at the other end of the top of the base 1. A lifting groove 402 is provided in the center of the vertical rail 4, and a lead screw 11 is vertically installed in the center of the lifting groove 402. A servo motor 14 is provided in the base 1 below the lead screw 11, and the output end of the servo motor 14 is connected to the lead screw 11 through a rotating shaft. A matching lead screw nut 17 is sleeved on the lead screw 11, and a mounting bracket 5 is connected to the end of the lead screw nut 17 near the foot controller 3. A hinge seat 16 is connected to the end of the lead screw nut 17 away from the foot controller 3, and a detection component 12 is installed on the hinge seat 16. When the servo motor 14 works, it drives the lead screw 11 to rotate, so that the lead screw nut 17 moves upward along the vertical rail 4, which in turn drives the detection component 12 to move upward, so as to perform hollow detection at different height positions. This eliminates the need for staff to manually tap each one, making it less likely to miss any, and the effect is good.

[0025] For example, both sides of the top of the mounting bracket 5 are slidably connected to flip stamps 6, and the ends of the flip stamps 6 near the foot pedal controller 3 are connected by connecting rods 7. When the tapping sound indicates a hollow sound, the foot pedal controller 3 is released, the servo motor 14 stops working, and the connecting rods 7 are pressed down towards the wall, which drives the two flip stamps 6 to approach the wall and mark the hollow area. The operation is very convenient.

[0026] For example, a battery 21 is installed inside the base 1, and a level 2 is embedded in the center of the top of the base 1. Ball bearings are evenly arranged on the bottom of the base 1. The level 2 is designed to detect the level of the ground, making it more functional. The ball bearing design makes the device easy to move and more convenient to use.

[0027] Please see Figure 2 The two sides of the vertical rail 4, which are away from the foot pedal controller 3, protrude outward to form side plates 8. Rollers 9 are evenly installed on the side plates 8, which are away from the foot pedal controller 3. The rollers 9 are all vertically set. The roller design makes the device move more smoothly against the wall and will not damage the wall. The design is more reasonable.

[0028] Please see Figure 1 and Figure 4 The vertical rails 4 at both ends of the lifting groove 402 are provided with through grooves 401, and the two ends of the nut 17 pass through the through grooves 401 and are connected to the mounting frame 5 and the hinge seat 16 respectively. The through groove 401 design allows the nut 17 to drive the mounting frame 5 and the hinge seat 16 on the outside of the vertical rail 4 to move, which is a more reasonable design.

[0029] Please see Figure 3 and Figure 4The mounting bracket 5 includes a U-shaped frame 501 and uprights 502. The inner width of the U-shaped frame 501 matches the outer width of the vertical rail 4. Uprights 502 are integrally connected to both sides of the U-shaped frame 501. Each upright 502 has a mounting groove 503 at its top and a compression groove 504 at its bottom. A compression spring 505 is installed inside each compression groove 504. The flip-up stamps 6 are shaped to match the mounting grooves 503, and their bottoms are fixed with... The pressure plate 601, whose shape matches the compression groove 504, abuts against the end of the compression spring 505 near the foot pedal controller 3. Pressing the connecting rod 7 down toward the wall causes the two flipping stamps 6 to move closer to the wall. The pressure plate 601 presses against the compression spring 505, compressing the spring. When the connecting rod 7 is released, the compression spring 505 returns to its original position, thus resetting the flipping stamps 6 and preventing them from touching the wall and causing unnecessary damage.

[0030] Please see Figure 4 and Figure 5 The detection component 12 includes a hollow hammer 13, a gear 15, a rotating rod 18, a connecting seat 19, and a torsion spring 20. The rotating rod 18 passes through the hinge seat 16 and is rotatably connected to the hinge seat 16. The gear 15 is symmetrically arranged on both sides of the rotating rod 18. The connecting seat 19 is fixed at the center of the rotating rod 18, and the hollow hammer 13 is threadedly connected to the top of the connecting seat 19. The torsion spring 20 is sleeved on the rotating rod 18 inside the connecting seat 19, and one end of the torsion spring 20 is inserted into the inside of the connecting seat 19. The bottom of the hinge seat 16 is integrally connected to a backing plate 1601, and the other end of the torsion spring 20 abuts against the inside of the backing plate 1601. The design of one end of the torsion spring 20 being inserted into the inside of the connecting seat 19 and the other end abutting against the backing plate 1601 makes the torsion spring 20 less likely to fall off. The threaded connection design of the hollow hammer 13 allows the hollow hammer 13 to be replaced, making the design more reasonable.

[0031] Please see Figure 1 On both sides of the detection component 12, toothed plates 10 are evenly spaced on the vertical rails 4, and each toothed plate 10 meshes with a gear 15. The number of teeth on the toothed plate 10 is one-quarter of the number of teeth on the gear 15. During detection, the detection component 12 moves upward with the nut 17. When the gear 15 contacts the toothed plate 10, the upward movement of the detection component 12 will drive the gear 15 to rotate, which will drive the hollow hammer 13 to rotate in the direction of the through groove 401. The torsion spring 20 is compressed. When the gear 15 moves upward to the interval between two adjacent toothed plates 10, the torsion spring 20 resets, driving the hollow hammer 13 to rotate in the direction of the wall, thus realizing the knocking detection. The angle of rotation of the gear 15 is consistent each time, that is, the force on the torsion spring 20 is consistent, and the knocking force of the hollow hammer 13 is consistent when it resets.

[0032] Detailed Implementation: In use, the battery 21 provides power to the device. First, push the device to the wall to be tested, with the side plate 8 close to the wall. During testing, the foot pedal controller 3 is powered on, and the servo motor 14 works, driving the lead screw 11 to rotate, causing the lead screw nut 17 to move upward along the vertical rail 4, which in turn drives the detection component 12 to move upward. When the gear 15 contacts the toothed plate 10, the upward movement of the detection component 12 will drive the gear 15 to rotate, which will drive the hollow hammer 13 to rotate towards the through groove 401. The torsion spring 20 is compressed. When the gear 15 moves upward to the adjacent two... When the toothed plate 10 is at a certain interval, the torsion spring 20 resets, causing the hollow hammer 13 to rotate towards the wall for tapping detection. When the tapping sound indicates a hollow sound, the foot pedal controller 3 is released, the servo motor 14 stops working, and the connecting rod 7 is pressed down towards the wall, causing the two flipping stamps 6 to move closer to the wall and mark the hollow area. After detecting one position, the device is retracted, causing the side plate 8 to leave the wall. The foot pedal controller 3 is then pressed, causing the detection component 12 to return to the lowest point. The device is then moved to the lower test position, and the above operation is repeated to complete the detection.

[0033] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately adapted to form other embodiments that can be understood by those skilled in the art.
