Description

Technical Field

[0001] This utility model relates to the field of highway maintenance technology, specifically a drilling machine for highway maintenance. Background Technology

[0002] Highway maintenance refers to the upkeep and maintenance of highways. Maintenance focuses on the entire process from the time a highway is built and opened to traffic, while repair focuses on restoring damaged sections. After a highway is built and opened to traffic, its quality gradually decreases due to wear and impact from vehicle wheels, erosion and weathering from natural forces such as rainstorms, floods, wind, sandstorms, snow, sun, and melting ice, as well as human damage and defects left over from construction. Therefore, maintenance and repair measures must be taken after a highway is built and opened to traffic, and continuous updates and improvements are necessary. To accelerate drainage and inspect road surface quality, drilling machines are generally used in highway maintenance.

[0003] Chinese utility model patent CN221742490U discloses a drilling machine for highway maintenance, including a main frame. A lifting seat is connected to the upper side of the main frame via a lifting mechanism. A drilling seat is provided on one side of the lifting seat. A buffer seat is slidably connected to the inner side of the lifting seat. A buffer spring is provided on the inner wall of the lifting seat. A buffer block is fixedly connected to one end of the buffer spring. One end of the buffer seat is pressed tightly against the buffer block. Support mechanisms are provided at the four corners of the main frame. A guide rail is provided on one side of the lifting seat. One end of the drilling seat is slidably mounted on the lifting seat via a guide groove and the guide rail. Through the designed buffer spring and buffer block, the drilling seat is installed and connected via the buffer block during use. When drilling, the drilling seat slides and pushes the buffer block against the buffer spring for cushioning, thereby reducing fatigue damage at the connection point of the drilling seat.

[0004] However, the above-mentioned patent still has the following shortcomings in actual use: when the patented drilling head drills holes in the road surface, it generates a lot of dust, which flies into the air and affects air quality. Utility Model Content

[0013] This utility model provides an improved drilling machine for highway maintenance, which has the following improvements and advantages compared with the prior art:

[0014] Firstly, this utility model uses movable wheels to move the vehicle frame on the road surface to a suitable drilling position. Then, two support components work to provide auxiliary support for the vehicle frame. Next, the first hydraulic push rod works to drive the lifting plate to slide downward on the vertical rail. The lifting plate drives the drilling motor and drilling head to move downward. At the same time, the drilling motor works to drive the drilling head to rotate. The drilling head rotates to perform drilling operations on the road surface. While drilling, the dust removal component works to absorb and filter the large amount of dust generated during drilling, ensuring that the dust will not fly into the air and thus will not affect the air quality.

[0015] Secondly, this utility model uses a lead screw slide to drive a moving plate to move horizontally back and forth a certain distance. The moving plate then drives the moving block and the moving rack to move horizontally back and forth a certain distance simultaneously. The moving rack drives the swing gear to rotate back and forth within a certain angle range. The swing gear uses two connecting shafts to drive the suction cup to rotate back and forth synchronously within a certain angle range, thereby increasing the suction range of the suction cup.

Detailed Implementation

[0025] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0026] This utility model, through improvements, provides a drilling machine for highway maintenance, such as... Figures 1-6 As shown, the system includes a frame, a support frame, vertical rails, a lifting plate, a first hydraulic push rod, a drilling motor, a drilling head, a dust removal assembly, and two support assemblies. The frame has a through hole at its center. Four movable seats are arranged in a rectangular pattern at the bottom of the frame, and movable wheels are rotatably mounted on each seat. The support frame is mounted on top of the frame. The vertical rails are vertically mounted on the inner wall of the support frame. The lifting plate is slidably mounted on the vertical rails. The first hydraulic push rod is vertically mounted on top of the support frame, and its output end is connected to the top of the lifting plate. The drilling motor is vertically mounted on the lifting plate, and the drilling head is mounted on the output shaft of the drilling motor. The drilling head is located above the through hole, and the dust removal component is installed on the frame. Two support components are symmetrically arranged on the frame. The frame is moved on the road surface to a suitable drilling position by the moving wheels. Then, the two support components work to provide auxiliary support to the frame. Next, the first hydraulic push rod works to drive the lifting plate to slide downward on the vertical rail. The lifting plate drives the drilling motor and the drilling head to move downward. At the same time, the drilling motor works to drive the drilling head to rotate. The drilling head rotates to perform drilling operations on the road surface. At the same time, the dust removal component works to absorb and filter the large amount of dust generated during drilling, ensuring that the dust will not fly into the air and thus will not affect the air quality.

[0027] Specifically, the dust removal assembly includes a dust removal base, a suction bucket, a swing gear, a swing component, a filter box, a filter component, a hose, a fan, a connecting pipe, an exhaust pipe, and two connecting shafts. The dust removal base is installed at the bottom of the vehicle frame, and the two connecting shafts are rotatably mounted on the dust removal base. The two sides of the suction bucket are respectively connected to the two connecting shafts. The swing gear is installed at the end of one of the connecting shafts. The swing component is installed at the bottom of the vehicle frame, the filter box is installed at the top of the vehicle frame, and the filter component is installed inside the filter box, with its top end extending to the outside of the filter box. Both ends of the hose are respectively connected to… The suction cup and the filter box are connected. The fan is horizontally installed on the top of the frame. The two ends of the connecting pipe are connected to the input end of the fan and the filter box, respectively. The exhaust pipe is installed on the output end of the fan. The dust generated by the drilling is drawn by the fan and enters the filter box through the suction cup and the hose. Then, the dust and gas are filtered by the filter components. The filtered clean gas is discharged through the connecting pipe and the exhaust pipe. The swing component drives the swing gear to reciprocate within a certain angle range. In turn, the swing gear drives the suction cup to reciprocate synchronously within a certain angle range through two connecting shafts, thereby increasing the suction range of the suction cup.

[0028] Specifically, the swing component includes a mounting frame, a horizontal rail, a moving block, a moving rack, a lead screw slide, and a moving plate. The mounting frame is located at the bottom of the vehicle frame, the horizontal rail is horizontally located at the bottom of the mounting frame, the moving block is slidably mounted on the horizontal rail, the moving rack is horizontally located at the bottom of the moving block and meshes with the swing gear, the lead screw slide is horizontally located at the bottom of the mounting frame, and the moving plate is mounted on the moving end of the lead screw slide and connected to the outer wall of the moving block. The working of the lead screw slide drives the moving plate to reciprocate horizontally a certain distance, which in turn drives the moving block and the moving rack to reciprocate horizontally a certain distance synchronously. The moving rack then drives the swing gear to reciprocate within a certain angle range.

[0029] Specifically, the filter component includes a filter element and two limiting rails. The two limiting rails are symmetrically arranged inside the filter box. The filter element is slidably installed on the two limiting rails, and the top of the filter element extends to the outside of the filter box. The filter element filters the dust and gas inside the filter box. The filter element is manually pulled upwards from the filter box periodically for replacement.

[0030] Specifically, the filter element has a pull groove on its top outer wall; the pull groove facilitates pulling the filter element upward.

[0031] Specifically, the support assembly includes a support plate and two second hydraulic push rods. The two second hydraulic push rods are symmetrically arranged on the top of the frame. The support plate is installed on the output ends of the two second hydraulic push rods. The bottom of the support plate is provided with multiple anti-slip grooves. The two second hydraulic push rods work to drive the support plate to move downward. The support plate moves downward and contacts the road surface to provide auxiliary support for the frame. The multiple anti-slip grooves increase the friction between the bottom of the support plate and the road surface.

[0032] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
