Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a drilling equipment for detecting foundation compaction and a method of using the same. Background Art

[0002] Compaction, also known as tamping, refers to the ratio of the dry density of compacted soil or other road construction materials to the standard maximum dry density, expressed as a percentage. Compaction determination primarily involves indoor standard density (maximum dry density). Road foundation compaction reflects the tightness and strength of each compacted layer of the roadbed. Only when the tightness and strength of each compacted layer meet the specified requirements can the overall strength, stability, and durability of the road foundation meet the requirements. If a layer fails to meet the compaction requirements before the next layer is filled, the overall strength, stability, and durability of the road foundation will be affected. Rework at this time will result in waste and seriously affect the construction progress, delaying the project. Therefore, compaction testing of the foundation is essential during road foundation construction.

[0003] When testing the compaction of road foundation, it is necessary to use a punching machine to drill holes in the foundation for sampling. When drilling, the lifting seat is controlled by the lifting motor, and the punching motor drives the punching drill to drill. However, during the drilling process, no protective measures are set, so that when the punching drill is drilling, external impurities can easily enter the punched hole, and when the punching drill is extracting samples, since there are no blocking measures, the sample can easily fall into the hole, resulting in sample loss, and repeated drilling is required, which not only increases the workload but also damages the foundation. In addition, if there are impurities such as stones and steel bars inside the foundation, the punching drill is prone to accidental jumping when it comes into contact with these hard objects, causing safety accidents, and easily damaging the foundation sample, thereby resulting in the inability to effectively test the compaction of the foundation.

[0019] Furthermore, in a preferred embodiment of the present invention, an active isolation mechanism is further included, wherein the active isolation mechanism is mounted on the top side of the punch body, and the active isolation mechanism is used to isolate the punch drill;

[0020] The active isolation mechanism includes a mounting top plate, the mounting top plate being mounted on the top side of the punch body, and four rotating isolation plates being rotatably mounted on the bottom side of the mounting top plate, the four rotating isolation plates being rotated to isolate the punch drill;

The four hemispherical blocks are movably installed in the four extrusion opening and closing grooves respectively.

[0026] A method for using a drilling device for detecting foundation compaction is provided, which is performed according to the above-mentioned drilling device for detecting foundation compaction, and comprises the following steps:

[0027] S1. Start the lifting motor to drive the lifting screw to rotate, drive the lifting slide to lift, the lifting slide drives the lifting seat to lift by driving the lifting block, and the drilling motor drives the drilling drill to drill holes in the foundation for sampling. The lifting seat moves down to squeeze the two squeezing transverse plates to move horizontally. The squeezing transverse plates move to drive the linkage frame to move. The linkage frame moves through the driving shaft in the toggle frame, so that the toggle frame drives the closed rotary cover to rotate and open through the closing shaft;

[0028] S2. When a problem occurs when the punching drill moves downward to punch a hole, the punching drill jumps abnormally, thereby squeezing any one or more jumping push racks to move. The jumping push rack moves horizontally on the sampling hole closing plate and drives the connecting rod to move through a driving seat. The driving connecting rod drives the transfer lifting rack to move through another driving seat. The transfer lifting rack moves and drives the two drive shafts to move in the two drive inclined holes, thereby driving the two drive racks to move, so that the two drive racks drive the push slide to move;

[0029] S3, pushing the slide to drive the driven inserting frame to move, so that the driven inserting frame is separated from the two driven slots, thereby separating the driven lifting block from the lifting slide;

[0030] S4. When the lifting seat moves down to punch holes, the lifting seat no longer squeezes the opening and closing frame. At this time, under the return force of the reset spring, the opening and closing frame is pulled down, and the opening and closing frame moves synchronously with the movement of the four hemispherical blocks, so that the four hemispherical blocks move in the four extrusion opening and closing grooves, and then drive the four opening and closing columns to rotate, so that the four opening and closing columns drive the four rotating isolation plates to rotate through the four synchronous rotating shafts, and then isolate the punching drill.

[0031] The beneficial effects of the punching device for foundation compaction detection and the use method thereof proposed by the present invention are:

[0032] In the present invention, through the setting of the sample blocking and sealing mechanism, when drilling and sampling the foundation, the two closed rotary covers can be automatically opened, and when the drilling drill is reset, the two closed rotary covers are reset to seal the drilled holes, thereby achieving the purpose of automatic opening and closing of the closed rotary covers and avoiding the problem of foundation samples in the drilling drill falling into the hole.

[0033] Furthermore, in the present invention, through the setting of the jumping separation mechanism, when the punch drill moves down to drill a hole, if a problem occurs during the punch drill drilling, causing the punch drill to jump abnormally, and then squeezing any one or more jumping push racks to move, the driving rack will be disengaged from the two driving slots, thereby separating the driving lifting block from the lifting slide, achieving fast and safe braking, and the entire process relies on the mechanical structure to ensure the stability of the triggering of the entire device, avoiding the problem of the punch drill continuing to move downward when abnormal jumping occurs.

[0034] Furthermore, in the present invention, through the setting of the active isolation mechanism, when the lifting seat moves down to punch holes, the lifting seat no longer squeezes the opening and closing frame. At this time, under the return force of the reset spring, the opening and closing frame is pulled down, and the movement of the opening and closing frame synchronously drives the four hemispherical blocks to move. The four hemispherical blocks move in the four extrusion opening and closing grooves, and then drive the four opening and closing columns to rotate. The four opening and closing columns drive the four rotating isolation plates to rotate through the four synchronous rotating shafts to enclose the punching drill, so that the punching drill is enclosed, and then the punching drill is isolated to avoid the punching drill being accidentally touched by the staff or subjected to accidental impact when drilling, thereby ensuring the normal progress of the sampling work.

It should be noted that in the embodiment of the present invention, when the punching drill 4 is drilling, the four rotating isolation plates 1002 rotate to surround the punching drill 4, thereby isolating the punching drill 4. The provision of the four positioning baffles 1010 also achieves the purpose of limiting the position of the four rotating isolation plates 1002.

[0065] More specifically, in the embodiment of the present invention, four synchronous rotating shafts 1003 are rotatably mounted on the mounting top plate 1001, and the four rotating isolation plates 1002 are respectively mounted on the four synchronous rotating shafts 1003; an opening and closing column 1004 is mounted on the top of each of the four synchronous rotating shafts 1003, and an opening and closing frame 1005 is movably mounted on the mounting top plate 1001, and the opening and closing frame 1005 is movably connected to the four opening and closing columns 1004.

The four hemispherical blocks 1007 are respectively movably installed in the four extrusion opening and closing grooves 1006. It should be noted that, in the embodiment of the present invention, when the lifting seat 2 moves downward and no longer squeezes the opening and closing frame 1005, under the pullback force of the reset spring 1009, the opening and closing frame 1005 is pulled downward, and the opening and closing frame 1005 moves synchronously with the movement of the four hemispherical blocks 1007, so that the four hemispherical blocks 1007 move in the four extrusion opening and closing grooves 1006, and then drive the four opening and closing columns 1004 to rotate, so that the four opening and closing columns 1004 drive the four rotating isolation plates 1002 to rotate through the four synchronous rotating shafts 1003, thereby surrounding the drilling rig 4.

[0068] In summary, the working principle of a drilling device for detecting foundation compaction provided by an embodiment of the present invention, that is, the method of using the drilling device according to the embodiment of the present invention, is as follows:

[0069] When drilling and sampling the foundation, the lifting motor 5 drives the lifting screw 7 to rotate, which is used to drive the lifting slide 6 to move up and down. The lifting slide 6 drives the lifting seat 2 to move up and down by driving the lifting block 903. At the same time, the punching motor 3 drives the punching drill 4 to drill holes in the foundation for sampling. When the lifting seat 2 moves down, the two extrusion transverse plates 809 are squeezed to move horizontally. The movement of the extrusion transverse plates 809 drives the linkage frame 807 to move. The linkage frame 807 slides horizontally in the transverse slide groove 810. The linkage frame 807 moves By driving the shaft 808 to move within the toggle frame 804 and simultaneously driving the toggle frame 804 to rotate, the toggle frame 804 drives the closed rotary cover 802 to rotate and open via the closed shaft 803, and at the same time, the closed torsion spring 806 is stressed, thereby achieving the purpose of automatically opening the two closed rotary covers 802 when the punch drill 4 is drilling a hole; in addition, when the punch drill 4 is reset, the two closed rotary covers 802 are reset to seal the drilled hole, and at the same time, the problem of the foundation sample in the punch drill 4 falling into the hole can be avoided;

[0070] Furthermore, when the punching drill 4 moves down to punch a hole, the punching drill 4 passes through the four jumping push racks 908. If a problem occurs when the punching drill 4 punches a hole, causing the punching drill 4 to jump abnormally, thereby squeezing any one or more jumping push racks 908 to move, the jumping push rack 908 moves horizontally on the sampling hole closing plate 801 along its own radial direction, and drives the connecting rod 911 to move through a driving seat 910, and the driving connecting rod 911 drives the transfer lifting rack 912 to move through another driving seat 910, and the transfer lifting rack 912 moves and drives the two driving seats 910 to move. The shaft 914 moves in the two driving inclined holes 915, thereby driving the two driving frames 913 to move, so that the two driving frames 913 drive the push slide 905 to move, and the push slide 905 slides horizontally in the sliding groove 906, and the return spring 907 is forced to contract, so that the push slide 905 drives the driving inserting frame 901 to move, so that the driving inserting frame 901 is separated from the two driving slots 904, thereby separating the driving lifting block 903 from the lifting slide 6, avoiding the problem of the punching drill 4 continuing to move downward when abnormal jumping occurs;

[0071] Furthermore, when the lifting seat 2 moves downward to punch holes, the lifting seat 2 no longer squeezes the opening and closing frame 1005. At this time, under the return force of the reset spring 1009, the opening and closing frame 1005 is pulled downward, and the opening and closing frame 1005 moves synchronously to drive the four hemispherical blocks 1007 to move, so that the four hemispherical blocks 1007 move in the four extrusion opening and closing grooves 1006, and then drive the four opening and closing columns 1004 to rotate, so that the four opening and closing columns 1004 drive the four rotating isolation plates 1002 to rotate through the four synchronous rotating shafts 1003, thereby isolating the drilling drill 4, avoiding the drilling drill 4 from being accidentally touched by the staff or subjected to accidental impact when drilling, and ensuring the normal progress of the sampling work.
