Description

Technical Field

[0001] This utility model relates to the field of traffic engineering equipment technology, and in particular to a road drilling device for traffic engineering. Background Technology

[0002] In the process of transportation engineering construction, road drilling is a fundamental and crucial operation, widely used in many construction stages such as traffic sign installation, guardrail fixing, and road inspection. While currently available road drilling equipment can meet basic drilling needs, it has revealed many problems that urgently need to be addressed in practical use.

[0003] However, in existing technologies, traditional drilling equipment mostly adopts manual adjustment mode for drilling parameter adjustment. For example, when facing different geological conditions, such as hard rock sections and soft soil sections, operators need to manually adjust the motor speed and torque based on experience. This adjustment method is not only inefficient and difficult to adapt to complex and changing construction environments, but also has a large adjustment error. If the parameters are not set properly, insufficient speed and torque when drilling hard rock will lead to increased drill bit wear and a significant reduction in drilling efficiency; while when drilling in soft soil, excessive speed and torque will cause the borehole diameter to expand and the borehole wall to collapse, seriously affecting the drilling quality and subsequent construction safety. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a road drilling device for traffic engineering.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a road drilling device for traffic engineering, comprising a moving mechanism, a controller installed at the front end of the moving mechanism, a precision drilling mechanism provided at the upper end of the moving mechanism, and a quantitative water supply mechanism provided at the upper end of the moving mechanism.

[0006] The precision drilling mechanism includes a support frame, with a hydraulic cylinder installed through the upper end of the support frame. Vertical guide seats are fixedly installed on both inner side walls of the support frame. A movable plate is slidably installed between the two sets of vertical guide seats. A variable speed motor is fixedly installed at the upper end of the movable plate. A drill rod is rotatably installed through the lower end of the movable plate. A drill bit is installed at the lower end of the drill rod. A depth sensor is fixedly installed at one end of the movable plate.

[0007] Preferably, the extended end of the hydraulic cylinder is fixed to the upper end of the moving plate, and the upper end of the drill rod is fixed to the output end of the variable speed motor.

[0008] Preferably, the lower end of the support frame is fixed to the upper end of the moving mechanism, and both the variable speed motor and the depth sensor are connected to the controller signal.

[0009] Preferably, the quantitative water supply mechanism includes a water tank and a pump body. A circular annular pipe is fixedly installed at the lower end of the movable plate. A sliding seat is slidably installed through one side of the support frame. A shaped connecting pipe is installed through one side of the sliding seat. Multiple sets of nozzles are fixedly connected to the lower outer wall of the circular annular pipe. A flow sensor is fixedly installed on the inner wall of the shaped connecting pipe. A folded pipe is fixedly installed at the upper drain outlet of the pump body. A water supply pipe is fixedly installed at the water inlet of the pump body.

[0010] Preferably, a water level sensor is fixedly installed inside the water tank, and the lower ends of both the water tank and the pump body are fixed to the upper end of the moving mechanism.

[0011] Preferably, one end of the irregularly shaped connector is connected to the outer wall of the annular tube, and the other end of the irregularly shaped connector is fixed to the other end of the folded tube.

[0012] Preferably, the other end of the water supply pipe extends into the interior of the water tank, and the pump body, flow sensor, and water level sensor are all connected to the controller signal.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by setting up a precision drilling mechanism, the controller is connected to the hydraulic cylinder, variable speed motor and depth sensor. The rotation speed of the drill rod can be precisely adjusted according to different geological conditions to meet diverse drilling needs. The depth sensor can monitor the drilling depth in real time and feed it back to the controller. When the set depth is reached, drilling will automatically stop, avoiding drilling too deep or too shallow, and greatly improving the accuracy and quality of drilling operations.

[0015] 2. In this utility model, by setting up a quantitative water supply mechanism, the flow sensor monitors the water supply in real time and transmits the data to the controller. The controller accurately controls the pumping flow rate of the pump body according to the actual needs of the drilling operation, so as to achieve quantitative water supply. This can effectively reduce dust and avoid excessive mud production due to improper water supply, optimize the construction environment, and reduce mud treatment costs. Secondly, the water level sensor monitors the water level in the water tank in real time. When the water level is lower than the set value, it sends a signal to the controller to remind the operator to add water in time, ensuring the continuity of water supply and avoiding construction interruption due to water shortage.

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a road drilling device for traffic engineering, including a moving mechanism 1, a controller 11 installed at the front end of the moving mechanism 1, a precision drilling mechanism 2 provided at the upper end of the moving mechanism 1, and a quantitative water supply mechanism 3 provided at the upper end of the moving mechanism 1.

[0024] The precision drilling mechanism 2 includes a support frame 21. A hydraulic cylinder 23 is installed through the upper end of the support frame 21. Vertical guide seats 27 are fixedly installed on both inner side walls of the support frame 21. A movable plate 24 is slidably installed between the two sets of vertical guide seats 27. A variable speed motor 25 is fixedly installed on the upper end of the movable plate 24. A drill rod 26 is rotatably installed through the lower end of the movable plate 24. A drill bit 22 is installed on the lower end of the drill rod 26. A depth sensor 28 is fixedly installed on one end of the movable plate 24. The extended end of the hydraulic cylinder 23 is fixed to the upper end of the movable plate 24. The upper end of the drill rod 26 is fixed to the output end of the variable speed motor 25. The lower end of the support frame 21 is fixed to the upper end of the moving mechanism 1. The variable speed motor 25 and the depth sensor 28 are both signal-connected to the controller 11.

[0025] The specific settings and functions of this embodiment are described below. The support frame 21 has a rectangular frame structure and is made of high-strength aluminum alloy material. It has both lightweight and high-strength characteristics, which can effectively reduce the overall weight of the device and ensure the structural stability during drilling operations. The four corners of the frame adopt a reinforcing rib structure design to further enhance the frame's resistance to deformation.

[0026] The hydraulic cylinder 23 is vertically installed through the middle of the upper end of the support frame 21. Its cylinder barrel is fixedly connected to the support frame 21 through a flange. The hydraulic cylinder 23 adopts a double-acting piston structure and is equipped with a high-precision displacement sensor, which can accurately control the extension and retraction distance of the piston, thereby realizing precise lifting and lowering control of the moving plate 24 to meet the needs of different drilling depths.

[0027] Two sets of vertical guide seats 27 are symmetrically fixedly installed on the inner side walls of the support frame 21. The surface of the vertical guide seat 27 is provided with a straight groove, and a wear-resistant polytetrafluoroethylene slider is embedded in the groove. It cooperates with the slider guide rails on both sides of the moving plate 24, so that the moving plate 24 can slide smoothly between the vertical guide seats 27, reduce frictional resistance, and improve the guiding accuracy of the moving plate 24.

[0028] The moving plate 24 is made of high-strength steel plate with rust-proof treatment. A variable speed motor 25 is fixedly installed at its upper end, and a drill rod 26 is rotatably installed through a bearing seat at its lower end to ensure that the drill rod 26 can rotate flexibly. A depth sensor 28 is fixedly installed at one end of the moving plate 24. The depth sensor 28 adopts the laser ranging principle and can measure the drilling depth in real time and accurately, and transmit the data to the controller 11.

[0029] The variable speed motor 25 is a variable frequency speed control motor with a wide speed range and high torque output characteristics. It can precisely adjust the motor speed and torque according to different geological conditions and drilling requirements through the controller 11. The drill rod 26 is made of hollow alloy steel and can be filled with water for cooling and slag removal. Its upper end is fixedly connected to the output end of the variable speed motor 25 through a coupling, and its lower end is equipped with a detachable drill bit 22, which makes it convenient to change the appropriate drill bit 22 according to different drilling tasks.

[0030] The moving mechanism 1 provides basic support and mobility for drilling operations.

[0031] Example 2: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the quantitative water supply mechanism 3 includes a water tank 31 and a pump body 32. A circular annular pipe 33 is fixedly installed at the lower end of the moving plate 24. A sliding seat 34 is slidably installed through one side of the support frame 21. A shaped connecting pipe 35 is slidably installed through one side of the sliding seat 34. Multiple sets of nozzles 36 are fixedly connected to the lower outer wall of the circular annular pipe 33. A flow sensor 37 is fixedly installed on the inner wall of the shaped connecting pipe 35. A folded pipe 38 is fixedly installed at the upper drain outlet of the pump body 32. A water supply pipe 39 is fixedly installed at the inlet of the pump body 32. A water level sensor 310 is fixedly installed inside the water tank 31. The lower ends of the water tank 31 and the pump body 32 are both fixed to the upper ends of the moving mechanism 1. One end of the shaped connecting pipe 35 is connected to the outer wall of the circular annular pipe 33. The other end of the shaped connecting pipe 35 is fixed to the other end of the folded pipe 38. The other end of the water supply pipe 39 extends into the interior of the water tank 31. The pump body 32, the flow sensor 37, and the water level sensor 310 are all signal-connected to the controller 11.

[0032] The overall effect of this embodiment is that the water tank 31 is made of cylindrical stainless steel, which has good corrosion resistance and sealing performance. The water tank 31 is equipped with reinforcing ribs inside to enhance the structural strength of the water tank 31 and prevent the water tank 31 from deforming during transportation and use. The top of the water tank 31 is equipped with a water inlet and a sealing cap for easy water filling. The side is equipped with a water level observation window to directly view the water level in the water tank 31. The water level sensor 310 fixedly installed inside the water tank 31 adopts the ultrasonic ranging principle, which can monitor the water level in the water tank 31 in real time and feed the data back to the controller 11.

[0033] Pump body 32 is a variable frequency centrifugal pump with adjustable flow rate and stable head. Its upper drain outlet is connected to folded pipe 38 through flange. Folded pipe 38 is made of flexible rubber and can be bent and deformed within a certain range to adapt to the lifting and lowering movement of moving plate 24. Water inlet is connected to water supply pipe 39 through flange. Water supply pipe 39 is made of high pressure resistant plastic and extends into the interior of water tank 31 at one end. A filter screen is installed at the water inlet to prevent impurities in water tank 31 from entering pump body 32 and affecting the normal operation of pump body 32.

[0034] The annular tube 33 is fixedly installed at the lower end of the movable plate 24. It has a circular structure and is made of stainless steel, which has good corrosion resistance. Multiple sets of nozzles 36 are uniformly fixedly connected to the lower outer wall of the annular tube 33. The nozzles 36 are atomizing nozzles 36, which can atomize water and spray it out to increase the water mist coverage area and improve the dust suppression effect.

[0035] A sliding block 34 is slidably installed through one side of the support frame 21. The sliding block 34 can slide up and down along the side of the support frame 21 to accommodate the lifting and lowering of the moving plate 24. A special-shaped pipe 35 is installed through one side of the sliding block 34. The special-shaped pipe 35 is a bent pipe structure. A flow sensor 37 is fixedly installed on its inner wall. The flow sensor 37 adopts the principle of electromagnetic induction and can monitor the water flow in real time and accurately, and transmit the data to the controller 11. One end of the special-shaped pipe 35 is connected to the outer wall of the annular pipe 33 through a quick connector, and the other end is fixedly connected to the other end of the folded pipe 38 through a flange, which facilitates disassembly and maintenance.

[0036] The method of use and working principle of this device: The moving mechanism 1 allows the operator to easily push the device to the drilling position. Once the device reaches the designated position, the self-locking device of the moving mechanism 1 is used to securely fix the device to the ground.

[0037] Then, according to the construction requirements, the operator sets the drilling depth parameters on the high-definition touch screen of the controller 11, and at the same time sets the speed and torque parameters of the variable speed motor 25. After receiving the instruction, the controller 11 transmits the control to the hydraulic cylinder 23 and the variable speed motor 25. The hydraulic cylinder 23 starts to work, pushing the moving plate 24 to move downward along the vertical guide seat 27. The drill rod 26 and drill bit 22 at the lower end of the moving plate 24 descend accordingly. The variable speed motor 25 drives the drill bit 22 to rotate through the drill rod 26. At the same time, the depth sensor 28 measures the distance between the drill bit 22 and the initial position in real time and feeds the data back to the controller 11. When the preset drilling depth is reached, the controller 11 immediately issues a stop signal, and the hydraulic cylinder 23 stops moving, thus achieving precise control of the drilling depth.

[0038] Finally, before the drilling operation begins, the operator sets the water supply flow parameters on the controller 11. The controller 11 sends a start signal to the pump body 32, and the variable frequency centrifugal pump starts working, drawing water from the water tank 31 through the water supply pipe 39. After being pressurized by the pump body 32, the water flows through the folded pipe 38 and the irregularly shaped connector 35 into the annular pipe 33. The flow sensor 37 on the inner wall of the irregularly shaped connector 35 uses the principle of electromagnetic induction to monitor the water flow in real time and transmits the flow data to the controller 11. Multiple sets of nozzles 36 on the lower outer wall of the annular pipe 33 spray out the water that enters. This water evenly covers the drilling area and comes into full contact with the dust generated during the drilling process, making the dust particles wet and heavier, thus settling to the ground and effectively suppressing dust from flying.

[0039] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
