Description

Technical Field

[0001] This invention belongs to the field of building construction testing technology, and in particular relates to a device for testing the compaction degree of building foundations. Background Technology

[0002] After the building foundation is completed, its compaction degree needs to be tested, which is one of the key indicators for measuring construction quality. Currently, when testing it, a lifting mechanism is used to control the fixed cylinder to move downward. When the sampling ring cutter contacts the ground surface, the first hydraulic cylinder pushes the sampling ring cutter to embed it into the foundation. Then the second hydraulic cylinder is activated, and at the same time the second motor rotates, the soil cutting drill rod rotates at high speed and gradually inserts into the foundation. The first motor drives the rotating table to rotate, and at the same time the sampling ring cutter rotates at high speed to cut the soil, forming an annular groove around the sampling ring cutter. The lifting mechanism is reset, and the sampling ring cutter and the surrounding soil are pried out using the rod.

[0003] However, during the extraction process, there is a problem of excessive crushing inside the foundation. After the materials are broken and mixed together, it is difficult to accurately detect the compaction degree of the foundation at different depths. Summary of the Invention

Detailed Implementation

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] like Figures 1-6 The diagram shows a structural representation of a building foundation compaction testing device according to an embodiment of the present invention. The device includes a base plate 1, a vertical rod 2, a top rod 3, a primary drilling mechanism 100, a secondary drilling mechanism 200, a directional separation mechanism 300, and a horizontal warping mechanism 400. The vertical rod 2 is vertically mounted on the upper surface of the base plate 1. The top rod 3 is positioned at the top of the vertical rod 2 and is parallel to the base plate 1. The primary drilling mechanism 100 is vertically mounted at one end of the top rod 3 and is used for drilling holes in the building foundation. The secondary drilling mechanism 200 is slidably mounted at the other end of the top rod 3, and is embedded at its bottom end. Secondary drilling and sampling are performed when the hole is formed. The directional separation mechanism 300 is located inside the working end of the secondary drilling mechanism 200 and is precisely cut off after being embedded to a specified depth at the working end of the secondary drilling mechanism 200. The horizontal warping mechanism 400 is rotatably mounted on the vertical rod 2. One end of the horizontal warping mechanism 400 is connected to the secondary drilling mechanism 200, and the other end is connected to the directional separation mechanism 300, so that the height of the secondary drilling mechanism 200, the directional separation mechanism 300, and the horizontal warping mechanism 400 can be adjusted when the horizontal warping mechanism 400 swings back and forth.

[0040] The foundation compaction testing device provided in this application can sample foundations at different depths during actual use. During the sampling process, the foundation at the corresponding depth can be cut. The cut blocks of material fall automatically under gravity, and the compaction quality at different depths is tested according to the order of falling. This effectively avoids the random distribution of materials and enables accurate testing at each depth, thereby improving the accuracy of the test.

[0041] In one embodiment of the present invention, a caster is installed at the bottom of the base plate 1, and a brake pedal is installed on the side of the caster to lock the wheel when it reaches the designated position; in addition, to facilitate overall rotation, a rotating seat can be arranged at the bottom of the base plate 1 during actual use so that after one drilling is completed, the whole thing can be rotated 180 degrees so that the secondary drilling mechanism 200 and the orientation separation mechanism 300 are directly above the hole on the foundation.

[0042] like Figure 1 As shown, in a preferred embodiment of the present invention, the primary hole-forming mechanism 100 includes a longitudinal rotating shaft 4, a spiral section 5, and a motor 6;

[0043] The longitudinal rotating shaft 4 is rotatably mounted on the end of the top rod 3, and the bottom end of the longitudinal rotating shaft 4 is provided with a sharp part;

[0044] The bottom of the longitudinal rotating shaft 4 is also equipped with a spiral part 5, and the edge of the spiral part 5 is provided with a sharp protrusion. The longitudinal rotating shaft 4 is driven by a motor 6 arranged at the top.

[0045] In the specific implementation of this embodiment, after the spiral part 5 is in the drilling position, the motor 6, driven by the external controller, drives the longitudinal rotating shaft 4 and the spiral part 5 to rotate synchronously, and the drilling work is carried out when the spiral part 5 is downward.

[0046] like Figure 1 and Figure 3 As shown, in another preferred embodiment of the present invention, the secondary hole-forming mechanism 200 includes an outer cylinder 7, an inner cylinder 8, a storage cavity 9, an inclined rod 10, and a T-rod 11;

[0047] The T-bars 11 are arranged in pairs, the T-bars 11 are slidably connected to the top rod 3, and the bottom end of the T-bars 11 is equipped with a diagonal rod 10.

[0048] An outer cylinder 7 is installed at the bottom end of the inclined rod 10, and an inner cylinder 8 is arranged inside the outer cylinder 7, and a storage cavity 9 is formed between the outer cylinder 7 and the inner cylinder 8.

[0049] In the specific implementation of this embodiment, the accompanying drawings are used as a reference. Figure 1 Based on the outer cylinder 7 being directly above the hole, when the outer cylinder 7 and the inner cylinder 8 move downwards, the outer side of the inner cylinder 8 contacts the inner wall of the hole, and the material is drilled by the outer cylinder 7. The drilled material remains in the storage cavity 9.

[0050] like Figure 1 , Figure 2 and Figure 3 As shown, in another preferred embodiment of the present invention, the directional separation mechanism 300 includes a crossbar 12, a telescopic member 13, a pull rod 14, a swing rod 15, a groove 16, and a sealing layer 17;

[0051] The pull rod 14 is slidably mounted on the outer cylinder 7, and a swing rod 15 is hinged to the side of the pull rod 14. The swing rod 15 is slidably connected to the groove 16 opened on the inner cylinder 8.

[0052] A sealing layer 17 is also bonded inside the groove 16 to prevent material from seeping into the inner cylinder 8.

[0053] A crossbar 12 is installed on the inner side of the T-bar 11, and a telescopic member 13 is installed on the bottom surface of the crossbar 12. The telescopic member 13 is fixedly connected to the pull rod 14.

[0054] In the specific implementation of this embodiment, the telescopic component 13 described in this application can be a linear drive device such as a pneumatic cylinder, hydraulic cylinder, electric cylinder, or electric telescopic rod, which will not be described in detail here. When the material stays in the storage cavity 9, the telescopic component 13 pulls the pull rod 14 to move synchronously along the outer cylinder 7. When the pull rod 14 moves, it also pulls the swing rod 15 to slide along the groove 16. The sealing layer 17 undergoes slight deformation during contact with the swing rod 15 to ensure sealing performance. When the swing rod 15 extends out of the inner cylinder 8, it cuts the material in the storage cavity 9. When the material is discharged after sampling, the telescopic component 13 pushes the pull rod 14 to slide in the opposite direction. The pull rod 14 pulls the swing rod 15 to stay in the inner cylinder 8 again. The cut block material falls automatically under the action of gravity, and the compaction quality at different depths is detected according to the order of falling, thereby effectively avoiding the random distribution of materials and enabling accurate detection at each depth, thus improving the accuracy of detection.

[0055] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 As shown, in another preferred embodiment of the present invention, the horizontal warping mechanism 400 includes a rotating shaft 18, a movable rod 19, an irregular groove 20, a strip groove 21, a slider 22, and a movable block 23;

[0056] The rotating shaft 18 is rotatably mounted on the vertical rod 2. A movable rod 19 is installed at the end of the rotating shaft 18, and a special-shaped groove 20 is provided on the vertical rod 2 for the movable rod 19 to swing.

[0057] The movable rod 19 has a strip groove 21, and a slider 22 is slidably installed in the strip groove 21. A movable block 23 is hinged to the side of the slider 22.

[0058] The slider 22 and the movable block 23 are arranged in pairs. The movable block 23 on one side is connected to the longitudinal rotating shaft 4, and the movable block 23 on the other side is connected to the pull rod 14.

[0059] In the specific implementation of this embodiment, the rotating shaft 18 in this application is connected to the external forward and reverse motor of the vertical rod 2 through an external coupling. When the forward and reverse motor is working, it drives the rotating shaft 18 to rotate. The rotating shaft 18 drives the movable rod 19 to rotate synchronously. When the movable rod 19 rotates, the sliders 22 at both ends slide along the strip groove 21 respectively, and the sliders 22 at both ends move in opposite directions in the height direction, thereby pushing the longitudinal rotating shaft 4 or the pull rod 14 at the corresponding position to move in the opposite direction, so as to accurately control the drilling depth.

[0060] like Figure 1 , Figure 5 and Figure 6 As shown, in another preferred embodiment of the present invention, a movable frame 24 is slidably mounted on the top rod 3, and a bushing 25 is mounted on the bottom end of the movable frame 24. The bushing 25 is rotatably connected to the longitudinal rotating shaft 4.

[0061] The motor 6 is located at the top of the movable frame 24, and the motor 6 is also electrically connected to an external controller.

[0062] In the specific implementation of this embodiment, in order to prevent the longitudinal rotating shaft 4 from falling off during rotation, a limit ring is also provided on the longitudinal rotating shaft 4 at the position corresponding to the bushing 25. When the longitudinal rotating shaft 4 descends, the bushing 25 and the movable frame 24 are subjected to force and slide smoothly along the top rod 3. At the same time, since the motor 6 is installed on the movable frame 24, it can effectively avoid excessive motion interference during operation.

[0063] In summary, during use, the detection device is first placed in the designated position, and the rotating base is supported on the foundation. After the spiral part 5 is in the drilling position, the motor 6, driven by an external controller, drives the longitudinal rotating shaft 4 and the spiral part 5 to rotate synchronously. The rotating shaft 18 is connected to the external forward and reverse motor of the vertical rod 2 through an external coupling, and drives the rotating shaft 18 to rotate when the forward and reverse motors are working. The rotating shaft 18 drives the movable rod 19 to rotate synchronously. When the movable rod 19 rotates, the sliders 22 at both ends slide along the strip groove 21 respectively. A limit ring is set at the position corresponding to the bushing 25 on the longitudinal rotating shaft 4. When the longitudinal rotating shaft 4 descends, the spiral part 5 performs drilling downwards. After drilling is completed and the device is removed from the foundation, the spiral part 5 and the outer cylinder 7 are deflected by half a turn. When the outer cylinder 7 and the inner cylinder 8 are above the hole... With the movable rod 19 swinging again, a second drilling is performed, and the drilled material remains in the storage cavity 9. The telescopic component 13 pulls the pull rod 14 to move synchronously along the outer cylinder 7. When the pull rod 14 moves, it also pulls the swing rod 15 to slide along the groove 16. The sealing layer 17 undergoes slight deformation during contact with the swing rod 15 to ensure sealing performance. With the swing rod 15 extended out of the inner cylinder 8, the material in the storage cavity 9 is cut. When the material is discharged after sampling, the telescopic component 13 pushes the pull rod 14 to slide in the opposite direction. The pull rod 14 pulls the swing rod 15 to stop again in the inner cylinder 8. The cut block material falls automatically under the action of gravity, and the compaction quality at different depths is detected according to the order of falling, thereby effectively avoiding the random distribution of materials and enabling accurate detection at each depth, thus improving the accuracy of the detection.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
