Description

Technical Field

[0001] The present invention relates to the technical field of punching equipment, and particularly relates to a punching equipment for foundation compaction detection and its using method. Background Art

[0002] The compaction degree, also known as the tamping degree, refers to the ratio of the dry density of soil or other road-building materials after compaction to the standard maximum dry density, expressed as a percentage. The determination of the compaction degree mainly includes the indoor standard density (maximum dry density). The foundation compaction degree of a road reflects the compactness strength of each compaction layer of the roadbed. Only when the compactness strength of each compaction layer meets the regulations can the overall strength, stability and durability of the road foundation meet the requirements. For example, if the compaction degree of a certain layer is unqualified and the upper layer is filled, the overall strength, stability and durability of the road foundation will be affected. At this time, if rework is carried out, it will cause waste and seriously affect the construction progress, delaying the construction period. Therefore, it can be seen that during the construction of the road foundation, the compaction degree detection of the foundation is essential.

[0003] When detecting the compaction degree of a road foundation, it is necessary to punch holes in the foundation for sampling by a punching machine. When punching holes, the lifting seat is controlled to lift and lower by a lifting motor, and a punching drill is driven to punch holes by a punching motor. However, during the punching process, no protective measures are set, so that when the punching drill punches holes, foreign impurities in the outside are likely to enter the punched holes. And when sampling on the punching drill, due to the absence of any blocking measures, the sample is extremely easy to fall into the hole, resulting in the loss of the sample, thus requiring repeated punching, 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, when the punching drill contacts these hard objects, it is extremely easy to have accidental jumps, causing safety accidents and easily damaging the foundation sample, thus resulting in the problem that the compaction degree of the foundation cannot be effectively detected.

[0016] Furthermore, in the present invention, through the setting of the jumping separation mechanism, when the punching drill moves downward to drill a hole, if a problem occurs during the drilling of the punching drill, causing the punching drill to jump abnormally, thereby 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 is achieved by relying on the mechanical structure to ensure the stability of the triggering of the entire device, avoiding the problem of the punching drill continuing to move downward when it jumps abnormally.

[0017] 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.

[0037] In summary, the working principle of a drilling device for detecting the compactness of a foundation provided by the embodiment of the present invention, that is, the usage method of using the drilling device of the embodiment of the present invention is: 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 lift and lower. The lifting slide 6 drives the lifting seat 2 to lift and lower by driving the lifting block 903, and at the same time drives the drilling drill 4 to drill and sample the foundation through the drilling motor 3; when the lifting seat 2 moves downward, the two extrusion transverse plates 809 are squeezed to move horizontally, and the movement of the extrusion transverse plates 809 drives the linkage frame 807 to move, and the linkage frame 807 slides horizontally in the transverse slide groove 810, and the linkage frame 807 moves By driving the shaft 808 to move in the toggle frame 804 and driving the toggle frame 804 to rotate, the toggle frame 804 drives the closed rotary cover 802 to rotate and open through the closed shaft 803, and at the same time, the closed torsion spring 806 is stressed, so that the two closed rotary covers 802 can be automatically opened when the drilling drill 4 is drilling a hole; in addition, when the drilling drill 4 is reset, the two closed rotary covers 802 are reset to close the drilled hole, and the problem of the foundation sample in the drilling drill 4 falling into the hole can be avoided; Furthermore, when the drilling drill 4 moves downward to drill a hole, the drilling drill 4 passes through four jumping push racks 908. If a problem occurs when the drilling drill 4 is drilling a hole, causing the drilling 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, 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 to drive the two driving shafts 91 4 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 shrink, 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, so that the driving lifting block 903 is separated from the lifting slide 6, so as to avoid the problem that the punching drill 4 continues to move downward when it jumps abnormally; 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 holes, and ensuring the normal progress of the sampling work.
