Description

Technical Field

[0001] The invention relates to the technical field of road construction equipment, in particular to a punching sampling device for road construction detection. Background Art

[0002] In order to ensure the service life of the road, after the road construction is completed, it is generally necessary to test the construction quality of the road. Sampling can be completed by punching holes in the road surface after construction. By taking road samples to test the construction quality of the road surface, parameters such as the pavement thickness and compaction degree of the road surface can be understood. Special punching equipment is required when testing the construction quality of the road surface. For example, the invention patent with the announcement number CN117168881B discloses a drilling sampling device for road construction detection, including a positioning support seat, a first servo motor, a second servo motor, a sampling tube body, an anti-drop mechanism, a water drive mechanism, a diverter seat, a water tank and a self-cleaning mechanism. The invention drives the screw to rotate through the first servo motor, thereby driving the first slide seat and the connecting seat to rise and fall, thereby facilitating the sampling tube body and the sampling drill bit to adjust the drilling depth, and the first transmission belt cooperates with the first main pulley to link the second servo motor and the water drive mechanism, so that the second servo motor can not only drive the sampling tube body and the sampling drill bit to drill and sample, but also link the water drive mechanism to achieve quantitative extraction of water inside the water tank and quantitative delivery to the diverter seat, which is beneficial to the diverter seat to spray the water inside the diverter seat in an atomized manner to achieve dust reduction during the drilling process, thereby improving the structural linkage and dust reduction effect of the drilling sampling device for road construction detection; However, when drilling holes in the road surface, it is usually necessary to apply downward pressure to the drill bit. Since the road is a layered structure paved with multiple materials, the feed speed of the drill bit will also change when the drill bit is at different depths. The prior art generally uses a hand crank to drive the threaded rod to rotate or uses a motor to drive the threaded rod to rotate to lower the drill bit. Although the hand crank method can manually control the drill bit's descent speed, it requires a high level of technical proficiency from the staff and increases the staff's labor intensity. Although the method of driving the threaded rod with a motor saves the staff's physical strength, it is not convenient to flexibly adjust the drill bit's descent speed according to the drilling depth, and it is relatively rigid. When the descent speed applied to the drill bit is greater than the actual feed speed of the drill bit, such as when drilling into steel bars or relatively hard objects, the drill bit is difficult to continue to descend, and a reaction force is applied to the equipment body, causing the equipment to be lifted, which can easily cause damage to the drill bit and easily cause production accidents. When the descent speed applied to the drill bit is less than the actual descent speed of the drill bit, it will also affect the drilling speed and reduce work efficiency. Summary of the invention

[0003] In view of the deficiencies of the prior art, the present invention provides a drilling sampling device for road construction detection, which solves the technical problem that the prior device cannot automatically control the drill feed speed.

The pull ropes are used to realize the linkage of height adjustment of the slider one and the slider two. When the slider one is located at the top of the guide rod one, the slider two is located at the bottom of the guide rod two. When the slider two is located at the top of the guide rod two, the slider one can be located at the bottom of the guide rod one.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-4The present invention provides a technical solution: a drilling sampling device for road construction detection, comprising a vehicle body 1 and a drill bit 2. The vehicle body 1 is fixedly provided with a pair of guide rods 3 and a pair of guide rods 7. A slider 4 is slidably provided on the pair of guide rods 3. A mounting platform 5 is fixedly provided on one side of the slider 4. The drill bit 2 is rotatably installed under the mounting platform 5. The mounting platform 5 is provided with a power unit that drives the drill bit 2 to rotate. A water tank 6 is fixedly provided on the mounting platform 5. By filling the water tank 6 with water, the weight on the slider 4 can be increased, thereby generating downward pressure on the drill bit 2. A slider 2 8 is slidably arranged on the slider 2 8, a water tank 2 9 is fixedly arranged on one side of the slider 2 8, a top plate 34 is fixedly arranged on the top of a pair of guide rods 1 3 and a pair of guide rods 2 7, two guide wheels 10 are rotatably arranged on the top plate 34, a pull rope 11 is connected to the slider 1 4 and the slider 2 8, and the pull rope 11 is wound around the two guide wheels 10, the pulling direction of the pull rope 11 is changed by the two guide wheels 10, and the height adjustment linkage of the slider 1 4 and the slider 2 8 is realized by the pull rope 11, when the slider 1 4 is located at the top of the guide rod 1 3, the slider 2 8 is at the bottom of the guide rod 2 7 When the slider 28 is located at the top of the guide rod 27, the slider 14 can be at the bottom of the guide rod 13. The top plate 34 is fixedly installed with a water pump 12 and a reversing valve 13. The water tank 16 and the water tank 29 are connected to the reversing valve 13 through a hose 14. By starting the water pump 12 and cooperating with the reversing valve 13, the water in the water tank 16 can be transported to the water tank 29 or the water in the water tank 29 can be transported to the water tank 16, thereby forming a gravity difference. It is common knowledge for those skilled in the art to change the direction of the liquid pumped by the water pump 12 through the reversing valve 13. The specific structure will not be described in detail here. When sampling the hole, the water in water tank 2 9 is pumped into water tank 1 6. At this time, the gravity on slider 4 is greater than the gravity on slider 2 8. The gravity difference can make slider 4 drop and slider 2 8 rise, and the weight of water tank 6 generates downward pressure on drill bit 2, so it will not cause upward thrust to vehicle body 1. After the hole sampling is completed, the water in water tank 6 is transported to water tank 2 9. At this time, the downward pressure generated by water tank 2 9 on slider 2 8 is greater than the sum of the weights of all parts installed on slider 4, so that slider 4 can move upward, and the drill bit 2 can be pulled out of the drilled hole.

[0018] Specifically, a cavity 15 is opened in the mounting platform 5, and a rotating shaft 16 is rotatably arranged in the mounting platform 5, and the upper end of the rotating shaft 16 extends into the cavity 15. The bottom of the rotating shaft 16 extends to the outside of the mounting platform 5 and is fixedly provided with a connector 17. The drill bit 2 is connected to the rotating shaft 16 through the connector 17, which is convenient for disassembly and replacement of the drill bit 2. A pulley 18 is fixedly arranged on the rotating shaft 16 located in the cavity 15. The mounting platform 5 is fixedly connected to a motor 33, and a pulley 2 19 is fixedly connected to the power output end of the motor 33. The pulley 2 19 and the pulley 1 18 are connected by a belt 20. Starting the motor 33 can drive the drill bit 2 to rotate, thereby realizing power transmission.

[0019] Furthermore, a damping wheel 22 is provided on the top plate 34 between a pair of guide wheels 10, and the pull rope 11 is wound around the damping wheel 22 for at least one circle to increase the friction coefficient between the pull rope 11 and the damping wheel 22. By providing the damping wheel 22, the moving speed of the pull rope 11 can be limited to prevent the slider 14 and the slider 28 from rising or falling too fast, thereby preventing the water tank 2 9 from hitting the vehicle body when the drill bit 2 is pulled out of the drilled hole.

[0020] Specifically, a wheel frame 21 is fixedly mounted on the top plate 34 , and the damping wheel 22 is rotatably mounted in the wheel frame 21 . A rotary damper 23 for limiting the rotation speed of the damping wheel 22 is fixedly arranged on the outer side of the wheel frame 21 , and the rotation speed of the damping wheel 22 is limited by the rotary damper 23 .

[0021] Furthermore, a mounting frame 31 is fixedly installed at one end of the vehicle body 1 close to the drill bit 2, and a plurality of pulleys 32 are rotatably arranged inside the mounting frame 31. The plurality of pulleys 32 abut against the outer wall of the drill bit 2, thereby limiting the radial direction of the drill bit 2 and ensuring the verticality of the drill bit 2 and the vehicle body 1. The friction force on the drill bit 2 can be reduced by the rotatable pulleys 32.

[0022] Furthermore, a mounting plate 27 is fixedly installed on one side of the slider 28, and the water tank 29 is fixedly installed on the mounting plate 27. A lever 28 is hinged on the upper surface of the vehicle body 1, and a hook 29 for hanging the mounting plate 27 is provided on the side wall of the lever 28. When the device needs to be moved or stored and there is no water stored in the water tank 29, the slider 28 can be prevented from rising by pressing the hook 29 on the mounting plate 27, thereby preventing the slider 4 from falling, thereby preventing the drill bit 2 from falling and contacting the ground during transportation or storage.

[0023] Furthermore, a handle 25 is fixedly mounted on the vehicle body 1, and wheels 30 are mounted at the four corners of the bottom of the vehicle body 1 to facilitate the movement of the device.

[0024] Furthermore, a water tank three 24 is installed on the vehicle body 1, and water can be stored in the water tank three 24 to counterweight the side of the vehicle body 1 away from the drill bit 2, thereby reducing the risk of tipping over of the device. At the same time, the water stored in the water tank three 24 can also be used to supplement the water in the water tank one 6 or the water tank two 9.

[0025] Furthermore, a handle 26 is fixedly installed on the mounting platform 5. By providing the handle 26, the height of the mounting platform 5 can be manually controlled. By controlling the water content in the water tank 1 9 and the water tank 2 6, the weight of the slider 1 4 and the slider 2 8 can be adjusted. When the weights of the two are equal, the height of the mounting platform 5 can be easily adjusted by manually holding the handle 26, so that the worker can manually control the drill bit 2 to drill holes and take samples.

[0026] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0027] The working principle and use process of the present invention are as follows: when in use, first push the device to the position where drilling and sampling are required, start the motor 33 to rotate the drill bit 2, pull the lever 28 to move the hook 29 out from above the mounting plate 27, adjust the water flow direction through the reversing valve 13 and start the water pump 12 to transport the water in the water tank 2 9 to the water tank 1 6. After the transportation is completed, the drill bit 2 is pressed down by gravity and continues to move downward. The pulley 32 can limit the verticality of the drill bit 2. When the drill bit 2 drills to a hard layer, the resistance becomes greater, the descending speed automatically slows down, and no upward reaction force is applied to the device body, thereby ensuring the safety of drilling. When the drill bit 2 drills to a soft layer, it is blocked. When the water level in water tank 1 6 decreases, the descending speed automatically increases, thereby improving the drilling speed. After the drilling is completed, the reversing valve 13 is adjusted and the water pump 12 is started. When all the water in water tank 1 6 is transported to water tank 2 9, slider 2 8 will drop due to gravity, and the pull rope 11 can be used to pull slider 1 4 up, thereby extracting the drill bit 2 from the drilled hole. In addition, when it is necessary to manually control the descent of the drill bit 2, the weights borne by slider 1 4 and slider 2 8 can be adjusted by adjusting the water content in water tank 1 6 and water tank 2 9. When the weights borne by the two are equal or similar, the height of the mounting platform 5 can be easily adjusted by manually holding handle 2 26, thereby facilitating the worker to manually control the descent of the drill bit 2 for drilling and sampling.

[0028] The rotary damper 23, water pump 12 and reversing valve 13 used in the present invention are all existing conventional technologies, and their specific structures are not described in detail. In order to speed up the pumping speed of water between water tank 1 6 and water tank 2 9, a large flow pump should be selected. The attached drawings in the specification are structural schematic diagrams and do not represent the actual shapes and sizes of the final components.

[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
