DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example: Reference Figure 1-4 The shown simple combined road coring device includes a base 1, a circular hole is opened on the top of the base 1, and a turntable 2 is rotatably installed in the circular hole through a rotating assembly, an electric telescopic rod 6 is fixedly installed on the top of the turntable 2, the output end of the electric telescopic rod 6 passes through the turntable 2 and is provided with a cross-shaped plate 7, four sensors 8 are provided at the bottom of the cross-shaped plate 7, and an adjustment assembly adapted to the four sensors 8 is provided at the bottom of the base 1. A square hole is opened on the top of the turntable 2, a U-shaped top plate 11 is fixedly installed on the top of the turntable 2, a mounting plate 12 is slidably mounted on the U-shaped top plate 11 through a lifting assembly, a core drill 17 is rotatably installed at the bottom of the mounting plate 12, and a driving motor 18 adapted thereto is provided on the top of the mounting plate 12, a water tank 19 is provided on the top of the base 1, and a water outlet is opened on the water tank 19 and the base 1 together. A water outlet pipe 20 is sealed in the water outlet hole, and a water pump is provided on the water outlet pipe 20, and the water pump is connected to the mounting plate 12 through an induction assembly.

[0023] With the above structure, when in use, first move the device to an appropriate position, then start the electric telescopic rod 6 to drive the cross-shaped plate 7 and the four sensors 8 to move downward synchronously, and then sense the ground levelness through the four sensors 8. When it is sensed that the device and the ground are in a non-horizontal state, an electrical signal is transmitted to the adjustment component, and the horizontality of the base 1 is adjusted through the adjustment component until the base 1 and the ground are in a horizontal state. Then, the core drill 17 is driven to rotate one hundred and eighty degrees through the rotating component, and is driven downward by the lifting component to cooperate with the drive motor 18 to perform coring operations on the road. When the mounting plate 12 moves downward, the water pump is driven to work through the setting of the sensing component to realize the water discharge function.

[0024] like Figure 2 As shown, the rotating assembly includes an annular rack 3, a transmission groove is opened on the inner wall of the circular hole, the annular rack 3 is fixedly sleeved on the outer wall of the turntable 2, and a rotating motor 4 is fixedly installed on the top of the base 1. The output shaft of the rotating motor 4 extends into the transmission groove and is fixedly sleeved with a gear 5, and the gear 5 is meshed with the annular rack 3. This arrangement can realize the function of synchronous rotation of the turntable 2 by rotating the rotating motor 4.

[0025] Specifically, when the turntable 2 needs to be rotated, the rotating motor 4 is started to drive the gear 5 to rotate, and then through the meshing action of the gear 5 with the annular rack 3, the turntable 2 is driven to rotate, thereby adjusting the position of the cross plate 7 and the core drill 17.

[0026] like Figure 2 As shown, the adjustment component includes four adjusting hydraulic cylinders 9. Four equipment slots are opened at the bottom of the base 1. The four adjusting hydraulic cylinders 9 are fixedly installed in the four equipment slots respectively. The output ends of the four adjusting hydraulic cylinders 9 are provided with universal wheels 10. The four universal wheels 10 are provided with self-locking parts. The advantage of this arrangement is that through the arrangement of the four adjusting hydraulic cylinders 9, it is possible to achieve electrical connection between them and the four sensors 8, thereby realizing the automatic adjustment function of the horizontality of the base 1.

[0027] Specifically, when the levelness of the base 1 needs to be adjusted, the cross-shaped plate 7 is first driven downward by the electric telescopic rod 6, and then the levelness of the base 1 is adjusted by the four sensors 8. When the sensing base 1 is in a non-parallel state with the ground, the electrical signal is transmitted to the four adjusting hydraulic cylinders 9, and the horizontal state of the base 1 is adjusted by the adjusting hydraulic cylinders 9, so that the base 1 is parallel to the ground.

[0028] like Figure 4 As shown, the lifting assembly includes two screws 13, and lifting grooves are provided on the relative inner walls of the U-shaped top plate 11. A rectangular cavity is provided in the U-shaped top plate 11. The top ends of the two screws 13 are rotatably installed on the top inner walls of the lifting grooves, and the bottom ends of the two screws 13 are rotatably installed on the bottom inner walls of the two lifting grooves. A sprocket 14 is fixedly sleeved on the two screws 13, and a chain is installed on the two sprockets 14 in meshing relationship. A lifting motor 15 is provided on the top of the U-shaped top plate 11, and the output shaft of the lifting motor 15 is connected to the top of one of the screws 13. Lifting blocks 16 are threadedly installed on the two screws 13, and the opposite sides of the two lifting blocks 16 are fixedly connected to the two side portions of the mounting plate 12. The advantage of this arrangement is that by setting the two screws 13, the mounting plate 12 can be driven to achieve lifting movement.

[0029] Specifically, when coring operation is required, the coring drill 17 is driven to rotate by the driving motor 18, and the lifting motor 15 is started at the same time. Under the action of the two sprockets 14 and the chain, the two screws 13 are driven to rotate synchronously, thereby driving the two lifting plates 16 and the mounting plate 12 to move downward synchronously through the action of the thread.

[0030] like Figure 4As shown, the sensing component includes a travel main switch 25 and a travel auxiliary switch 26. A U-shaped side plate 21 is fixedly installed on the side of the water tank 19, and an L-shaped extrusion plate 22 is slidably installed in the U-shaped side plate 21. The L-shaped extrusion plate 22 is adapted to the mounting plate 12. A reset unit is provided at the bottom of the L-shaped extrusion plate 22. The top of the L-shaped extrusion plate 22 and the top inner wall of the U-shaped side plate 21 are provided with sensing grooves. The travel main switch 25 and the travel auxiliary switch 26 are respectively arranged in the two sensing grooves. The advantage of this arrangement is that through the arrangement of the L-shaped extrusion plate 22, when the mounting plate 12 moves downward to a suitable position, the L-shaped extrusion plate 22 can be squeezed to move downward synchronously, so that the travel main switch 25 and the travel auxiliary switch 26 are disconnected, thereby starting the water pump to reduce dust at the coring position.

[0031] Specifically, when the mounting plate 12 moves downward to a suitable position, its bottom contacts the L-shaped extrusion plate 22, and the core drill 17 contacts the ground. When the mounting plate 12 continues to move downward, the connection between the stroke main switch 25 and the stroke auxiliary switch 26 is disconnected, so that the water pump is turned on to spray water to reduce dust at the drilling position to avoid environmental pollution. No staff operation is required, and the degree of automation is high.

[0032] like Figure 3 、 4 As shown, the reset unit includes a reset spring 24, a through hole is opened at the bottom of the L-shaped extrusion plate 22, and a limit rod 23 is slidably installed in the through hole. The two ends of the limit rod 23 are respectively fixedly installed on the opposite inner walls of the U-shaped side plate 21, and the reset spring 24 is sleeved on the limit rod 23. One end of the reset spring 24 is fixedly installed on the bottom of the L-shaped extrusion plate 22, and the other end of the reset spring 24 is fixedly installed on the bottom inner wall of the U-shaped side plate 21. With this arrangement, when the extrusion effect on the L-shaped extrusion plate 22 is released, the elastic action of the reset spring 24 can drive it to realize the reset function.

[0033] Specifically, when the L-shaped extrusion plate 22 moves downward, the return spring 24 is squeezed. When the extrusion of the L-shaped extrusion plate 22 is released, the elastic action of the return spring 24 can drive the L-shaped extrusion plate 22 to move upward and reset, and the water pump is turned off through the contact of the stroke main switch 25 and the stroke auxiliary switch 26.

[0034] like Figure 2 As shown, a liquid level gauge 27 is provided on the side of the water tank 19, and a water inlet pipe is provided on the top of the water tank 19. The advantage of this arrangement is that the water level in the water tank 19 can be observed through the arrangement of the liquid level gauge 27.

[0035] Specifically, when it is necessary to observe the water level in the water tank 19, the liquid level meter 27 can be used for convenient observation, which is highly practical.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
