Description

Technical Field

[0001] The invention relates to a punching sampling device, in particular to a punching sampling device for municipal road construction detection. Background Art

[0002] The perforating sampling device for municipal road construction inspection is a device used to extract samples from the paved road surface for quality inspection and analysis. It is usually used in the inspection stage during the construction process or after completion to help evaluate the quality, thickness, structure and other physical properties of the pavement material to ensure that the road construction meets the design standards and construction specifications. The perforating sampling device for municipal road construction inspection is one of the very important equipment in municipal engineering. It can extract representative pavement samples and provide a reliable basis for subsequent road maintenance and use.

[0003] The current drilling sampling device usually uses a drill bit and a sampling rod to drill into the ground for sampling. The Chinese patent (application number 202410667112.6) discloses a drilling sampling device for municipal road inspection, including a support frame, on which a sampling structure that can adjust the downward sampling depth is provided, the sampling structure includes a rotatable sampling spiral rod, and the lower end of the sampling spiral rod is provided with a drill bit. One end of the support frame is respectively provided with a first fixed frame and a second fixed frame, and the first fixed frame is provided with a sample crushing structure that cooperates with the sampling structure. The sample crushing structure includes a rolling roller, and the lower end of the rolling roller is provided with a storage box that can move left and right with the swing of the rolling roller. The second fixed frame is provided with a fixed pressure structure that can press the area around the borehole, which effectively solves the problem that the drilling process in the prior art may cause cracks in the road surface around the hole, affecting sampling. In addition, since the soil samples taken out are in block shape, they usually need to be crushed separately before detection, which delays work efficiency. However, when the device is drilling and sampling, it is not possible to make the drill bit reciprocate after reaching the specified drilling depth, so that when the drilling depth is exceeded, ineffective drilling is caused, driving energy is wasted, and the drilling sampling efficiency is affected.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] See also Figure 1 to Figure 20 In an embodiment of the present invention, a drilling sampling device for municipal road construction detection includes a mobile frame 1 and a mounting frame arranged on the mobile frame 1, the mounting frame is provided with a drilling structure, the drilling structure is connected to an anti-displacement structure, and the anti-displacement structure is connected to the mobile frame 1; The drilling structure comprises a lifting mechanism arranged on the mounting frame, a driving mechanism connected to the lifting mechanism, and a drilling sampling mechanism arranged on the lifting mechanism and connected to the driving mechanism, the anti-displacement structure is connected to the lifting mechanism, and a reciprocating assembly is arranged on the lifting mechanism; When the driving mechanism is in operation, it is used to drive the lifting mechanism to vertically lift and lower the mounting frame. During the lifting and lowering adjustment process of the lifting mechanism, it is used to drive the drilling and sampling mechanism to lift and lower the mounting frame for drilling and sampling. At the same time, it is used to drive the anti-displacement structure to lift and lower the mounting frame 1, so that the anti-displacement structure contacts the ground or leaves the ground. When the lifting mechanism moves to the preset height of the reciprocating component, the reciprocating component is activated to adjust the reciprocating motion of the lifting mechanism.

[0038] In this embodiment, when the drilling structure is lifted and lowered, the anti-displacement structure can be driven to be lifted and lowered. When the driving mechanism is working, the lifting mechanism can be lifted and lowered on the mounting frame, and at the same time, the drilling sampling mechanism can be driven to operate, and the drilling sampling mechanism can follow the adjustment of the lifting mechanism on the mounting frame, so that the drilling sampling mechanism can perform drilling sampling operations on the road. By arranging a reciprocating component on the lifting mechanism, when the lifting mechanism moves to a preset height of the reciprocating component, the lifting mechanism can be adjusted to move back and forth through the adjustment of the reciprocating component, so that the drilling sampling mechanism that has been lowered can rise and reset. Through design, the drilling depth can be set to avoid the drilling sampling mechanism from drilling to a specified depth and continuing to drill, resulting in invalid work, which not only wastes driving energy but also delays work efficiency during sampling.

[0039] As a further solution of the present invention, two universal wheels are symmetrically arranged at one end of the bottom of the mobile frame 1, two mobile wheels are installed on the mobile frame 1 on one side of the two universal wheels, a push rod is fixedly connected to the mobile frame 1 on one side of the universal wheels, and four slots are opened on the mobile frame 1.

[0040] In this embodiment, the universal wheels and mobile wheels provided on the mobile frame 1 can make the mobile frame 1 convenient to move and adjust after loading, thereby improving the mobility of the device. The moving direction of the mobile frame 1 can be adjusted and controlled through the universal wheels, thereby improving the operating effect.

[0041] As a further solution of the present invention, the mounting frame includes two sliding columns 2 symmetrically mounted on the mobile frame 1, and the tops of the two sliding columns 2 are connected to the two ends of the top frame 3; An adjustment frame 4 is fixedly arranged at one side of the center of the top frame 3 , and two reinforcement rods 5 are symmetrically fixed at both ends of the top frame 3 .

[0042] In this embodiment, the top frame 3 on the top of the sliding column 2 is used for support, and the reinforcement rod 5 on the top frame 3 is fixedly connected to the push rod on the mobile frame 1 to ensure the installation stability of the top frame 3 on the mobile frame 1 and improve the stabilization effect.

[0043] As a further solution of the present invention, the lifting mechanism includes a lifting seat 14 whose two ends are respectively slidably connected to the two sliding columns 2 and four transmission rods 45 fixedly connected to the two ends of the lifting seat 14; A driving cylinder 15 is provided on one side of the lifting seat 14, and two rotating seats 16 are symmetrically fixedly connected to the lifting seat 14 on the opposite side of the driving cylinder 15. A mounting plate 17 is fixedly connected to the lifting seat 14, and a through slot 18 is opened on the mounting plate 17; A plug hole is formed at one end of each transmission rod 45 away from the lifting seat 14 , and a semicircular protrusion is fixedly provided on the inner wall of the plug hole.

[0044] In this embodiment, the lifting seat 14 slides on the sliding column 2, and the sliding column 2 can limit the sliding adjustment of the lifting seat 14 in the vertical direction. The driving cylinder 15 arranged on the lifting seat 14 meets the installation requirements of other components to ensure the connection effect.

[0045] As a further solution of the present invention, the anti-displacement structure includes an anti-displacement plate 6 arranged below the mobile frame 1, four threaded cylinders 7 arranged in a rectangular array on the anti-displacement plate 6, and a transmission mechanism respectively connected to each of the threaded cylinders 7; The four threaded barrels 7 are respectively and correspondingly inserted into the four slots provided on the mobile frame 1; The transmission mechanism includes four transmission columns 8 whose one ends are rotatably connected to four reinforcement rods 5 respectively, and a threaded column 13 fixedly connected to the other end of the transmission column 8, the threaded column 13 is threadedly connected to the threaded tube 7, and a limiting head 9 is fixed to the top of the transmission column 8, and a first vertical groove 10 is vertically opened on the transmission column 8 on one side of the limiting head 9, a spiral groove 11 is arranged on the transmission column 8 at one end of the first vertical groove 10, and a second vertical groove 12 is vertically opened on the transmission column 8 at one end of the spiral groove 11, and the second vertical groove 12 is arranged colinearly with the first vertical groove 10, and the first vertical groove 10, the spiral groove 11 and the second vertical groove 12 are all slidably connected to the semicircular protrusion on the inner wall of the plug-in hole at one end of the transmission rod 45.

[0046] In this embodiment, when the lifting seat 14 is lifted and lowered on the sliding column 2, since a plug hole is provided at one end of the transmission rod 45 fixedly arranged on the lifting seat 14, a semicircular protrusion is fixedly arranged on the inner wall of the plug hole, and the semicircular protrusion is slidably connected with the first vertical groove 10, the spiral groove 11 and the second vertical groove 12. When the lifting seat 14 descends, the semicircular protrusion will first slide in the track of the first vertical groove 10, and when the semicircular protrusion reaches the position of the spiral groove 11, it will slide along the spiral direction of the spiral groove 11. Since the transmission rod 45 is fixed on the lifting seat 14 and cannot rotate, and the transmission column 8 is rotatably connected to the reinforcement rod 5, the transmission column 8 will rotate when the lifting seat 14 descends. When the transmission column 8 rotates, the bottom fixed The threaded column 13 rotates together. Since the threaded column 13 is threadedly connected with the threaded tube 7, and the threaded tube 7 is slidably inserted in the four slots opened on the mobile frame 1 in a rectangular array, the threaded tube 7 will be forced to slide in the vertical direction, so that the anti-movement plate 6 can contact the ground or leave the ground. When the lifting seat 14 descends, the anti-movement plate 6 will contact the ground. When the lifting seat 14 rises, the anti-movement plate 6 will leave the ground. When the semicircular convex moves to the second vertical groove 12, it will not drive the transmission column 8 to rotate. At this time, the anti-movement plate 6 remains in a state of contacting the ground. Through the contact of the anti-movement plate 6 on the ground, the position of the mobile frame 1 can be kept in place. The mobile frame 1 is difficult to move and adjust at this time, ensuring stability during drilling.
