Description

Technical Field

[0001] This application relates to the field of quality inspection equipment technology, and more specifically, to a quality inspection device for construction engineering management. Background Technology

[0002] Construction engineering is a project that involves building houses and their associated peripheral products. It covers a wide range, including foundations, walls, beams, roofs and the spaces they form, as well as the wiring and pipes laid inside the building. When current quality inspection equipment inspects buildings, it usually drills holes in the building materials such as wood. The dust and debris generated in the holes are collected as samples for testing. Drilling holes in buildings often requires the use of quality inspection equipment for sampling and sending samples for testing. However, the sample storage of general operating equipment is too monotonous, making it difficult to separate and preserve multiple different samples, and difficult to sample materials at a specific depth in the building.

[0003] Therefore, a quality inspection device for construction project management is needed to solve the above problems. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] To address the technical problems mentioned in the background section, some embodiments of this application provide a quality inspection device for construction engineering management, comprising: a gripping part having a driving component and a gripping handle; a pushing cylinder fixedly mounted on the gripping part; a sampling head sleeved on the pushing cylinder and slidably engaged with it; a driving shaft fixedly mounted on the power output end of the driving component, a drill bit fixedly connected to one end of the driving shaft, one end of the pushing cylinder abutting against the drill bit and rotatably engaged with it, one end of the drill bit extending out of the sampling head, a sampling port opening on the lower side of the sampling head, an installation box mounted on the lower side of the sampling port, a sampling disk rotatably mounted inside the installation box, and multiple circumferentially distributed sampling chambers on the sampling disk for collecting samples discharged from the sampling port.

[0006] The set drive unit and push cylinder can drive the drill bit to drill holes. At the same time, the set sampling head can collect the debris drilled out by the drill bit. The set sampling plate can collect debris at different depths into different sampling chambers for easy analysis.

[0007] Furthermore, an adjustment box is fixedly connected to the sampling head. The adjustment box has an adjustment groove extending along the axis of the sampling head. A sliding rod is provided on the adjustment box, located above the adjustment groove and arranged along the extension direction of the adjustment box. A guide rod is fixedly connected to the adjustment box. The guide rod passes through the sliding rod and slides with the sliding rod. A guide spring is connected between the guide rod and the sliding rod.

[0008] Furthermore, a limiting sleeve is fitted onto the sliding rod, and the limiting sleeve slides in conjunction with the sliding rod. The adjusting box is provided with a scale extending along the adjusting groove, which is used to indicate the position of the limiting sleeve. A limiting screw is threaded onto the limiting sleeve, and the limiting screw passes through the limiting sleeve and abuts against the sliding rod at one end. An abutting head is fixedly connected to the limiting sleeve, passing through the adjusting groove. An abutting block is fixedly connected to the pushing cylinder, and an abutting block is fixedly connected to the abutting block, which is embedded in the adjusting box and slides along the extending direction of the adjusting groove. The abutting block has an arc-shaped guide surface that abuts against the abutting head.

[0009] By setting a limiting sleeve and an abutment block, the position of the limiting sleeve on the sliding rod can be adjusted. When the abutment block moves to the position of the limiting sleeve, it can push the abutment joint, thereby causing the sliding rod to move. The limiting sleeve can be limited by the setting limiting screw.

[0010] Furthermore, a connecting shaft that rotates with the sampling head is fixedly installed on the sampling plate. A limit ring is fixedly connected to the connecting shaft. A torsion spring is connected between the limit ring and the sampling head. The two ends of the torsion spring are fixedly connected to the sampling head and the limit ring, respectively.

[0011] The guide rod and guide spring are used to guide the sliding rod, and the guide spring also helps the sliding rod to move closer to the adjustment box.

[0012] Furthermore, a limiting notch is provided on the limiting ring, the limiting notch has a sidewall tangent to the concentric circle of the limiting ring, and a connecting rod is fixedly connected to the sliding rod, with a limiting head at one end of the connecting rod for embedding into the limiting notch.

[0013] By setting a limiting notch, the limiting head can be inserted into the limiting notch to limit the limiting ring.

[0014] Furthermore, the limiting head passes through the connecting rod and slides with the connecting rod. A limiting spring is provided between the limiting head and the connecting rod, and the two ends of the limiting spring are fixedly connected to the limiting head and the connecting rod, respectively.

[0015] The limiting spring makes the limiting head tend to embed into the limiting notch.

[0016] Furthermore, a guide rod is provided at each end of the adjustment groove, so that the line connecting the two guide rods is in the same direction as the extension direction of the adjustment groove, and the sliding rod moves along the axial direction of the guide rod.

[0017] The sliding rod is guided by two guide rods.

[0018] Furthermore, a disc is fixed inside the sampling head, which divides the inner cavity of the sampling head into two areas. The drill bit is located in one area, and the abutment block slides in the other area, pushing the cylinder through the disc.

[0019] The disc design prevents debris from obstructing the drill bit's movement.

[0020] The beneficial effects of this application are as follows:

[0021] 1. The set drive unit and push cylinder can drive the drill bit to drill holes. At the same time, the set sampling head can collect the debris drilled out by the drill bit. The set sampling plate can collect debris at different depths into different sampling chambers for easy analysis.

[0022] 2. By setting the limiting sleeve and the abutment block, the position of the limiting sleeve on the sliding rod can be adjusted. When the abutment block moves to the position of the limiting sleeve, it can push the abutment joint, thereby causing the sliding rod to move. The limiting screw can limit the limiting sleeve, so that when the predetermined depth is reached, the sample can be collected in different sampling chambers. Attached Figure Description

The gripping part 10 has a drive component and a gripping handle 11. The drive component can be configured as a motor, which drills holes in building materials through the gripping handle 11. The power output end of the drive component is fixed to the drive shaft 35, and one end of the drive shaft 35 is fixedly connected to the drill bit 19. A push cylinder 17 is fixedly installed on the gripping part 10. The push cylinder 17 is sleeved on the drive shaft 35 and one end abuts against the drill bit 19 and rotates with the drill bit 19. A sampling head 16 is sleeved on the push cylinder 17 and slides with the push cylinder 17. When drilling, one end of the sampling head 16 abuts against the surface of the building material and drills through the drill bit 19. When drilling, the push cylinder 17 and the sampling head 16 slide.

[0038] To collect the drilled sample debris, a sampling port 18 is provided at the lower end of the sampling head 16. A mounting box 36 is also fixedly installed below the sampling port 18 on the sampling head 16. A sampling disk 32 is rotatably connected inside the mounting box 36. The sampling disk 32 has three sampling chambers 33 distributed circumferentially. A through hole is provided on the mounting box 36 to allow the debris discharged from the sampling port 18 to fall into the sampling chambers 33. A connecting shaft 31 is rotatably connected to the lower end of the sampling head 16. A limiting ring 34 is fixedly connected to the connecting shaft 31. A torsion spring 13 connects the limiting ring 34 and the sampling head 16, with both ends of the torsion spring 13 fixedly connected to the sampling head 16 and the limiting ring 34, respectively. The sampling disk 32 and the connecting shaft 31 are fixed together by screws.

[0039] An adjustment box 21 is fixedly connected to the sampling head 16. Two adjustment slots 22 extending along the axis of the sampling head 16 are provided on the adjustment box 21. A sliding rod 23 is provided on the adjustment box 21, located on the upper side of the adjustment slot 22 and arranged along the extension direction of the adjustment box 21. A guide rod 24 is fixedly connected to the adjustment box 21. The guide rod 24 passes through the sliding rod 23 and slides with the sliding rod 23. A guide spring 25 is connected between the guide rod 24 and the sliding rod 23. There is one guide rod 24 at each end of the adjustment slot 22, so that the line connecting the two guide rods 24 is in the same direction as the extension direction of the adjustment slot 22. The sliding rod 23 moves along the axial direction of the guide rod 24.

[0040] A limiting sleeve 26 is fitted on the sliding rod 23, and the limiting sleeve 26 slides with the sliding rod 23. The adjusting box 21 is provided with a scale extending along the adjusting groove 22. The scale is used to indicate the position of the limiting sleeve 26. A limiting screw 27 is threaded on the limiting sleeve 26. The limiting screw 27 passes through the limiting sleeve 26 and one end abuts against the sliding rod 23. An abutting head 28 passing through the adjusting groove 22 is fixedly connected to the limiting sleeve 26. An abutting block 29 is fixedly connected to the pushing cylinder 17. An abutting block 29 is fixedly connected to the abutting block 29, which is embedded in the adjusting box 21 and slides along the extending direction of the adjusting groove 22. The abutting block 29 has an arc-shaped guide surface that abuts against the abutting head 28.

[0041] A limiting notch 12 is provided on the limiting ring 34. The limiting notch 12 has a sidewall tangent to the concentric circle of the limiting ring 34. A connecting rod 30 is fixedly connected to the sliding rod 23. One end of the connecting rod 30 is provided with a limiting head 15 for embedding into the limiting notch 12. When the sliding rod 23 is pushed by the drill bit 19, it will drive the connecting rod 30 to move, causing the limiting head 15 to disengage from the limiting notch 12.

[0042] The limiting head 15 passes through the connecting rod 30 and slides with it. A limiting spring 14 is provided between the limiting head 15 and the connecting rod 30, and the two ends of the limiting spring 14 are fixedly connected to the limiting head 15 and the connecting rod 30, respectively. After the sampling disk 32 is fixedly installed, the torsion spring 13 is twisted by rotating the sampling disk 32. At this time, under the action of the side wall of the limiting notch 12 which is tangent to the concentric circle of the limiting ring 34, the limiting head 15 will not limit the limiting ring 34, and the sampling disk 32 is rotated so that a sampling cavity 33 is directly opposite the lower side of the sampling port 18.

[0043] Working process or usage method:

[0044] 1. After the sampling disk 32 is fixedly installed, the torsion spring 13 is twisted by rotating the sampling disk 32. At this time, under the action of the side wall of the limiting notch 12 which is tangent to the concentric circle of the limiting ring 34, the limiting head 15 will not limit the limiting ring 34, and the sampling disk 32 is rotated to a sampling cavity 33 facing the lower side of the sampling port 18.

[0045] 2. By adjusting the positions of the two limiting sleeves 26 and observing the scale, the limiting sleeves 26 are positioned at the required sampling depth. After drilling, the abutment block 29 slides inside the sampling head 16. When it rotates to one of the required sampling depth positions, the abutment block 29 pushes the limiting sleeve 26, thereby driving the sliding rod 23 to move, causing the connecting rod 30 to move, and driving the limiting head 15 to disengage from the limiting notch 12. At this time, the limiting ring 34 rotates under the action of the torsion spring 13 until the other limiting head 15 is embedded in the limiting notch 12 to position the limiting ring 34. At this time, the other sampling chamber 33 is located directly below the sampling port 18 and can collect debris samples.

[0046] 3. When the abutment block 29 moves to the position of another limiting sleeve 26, it also pushes the limiting sleeve 26, causing the limiting head 15 to disengage from the limiting notch 12. Under the action of the torsion spring 13, the limiting ring 34 continues to rotate, so that the last sampling chamber 33 is directly opposite the lower side of the sampling port 18, realizing the collection of samples at two different depth positions.
