Description

Technical Field

[0001] The utility model relates to the technical field of engineering detection devices, in particular to a road surface coring device. Background Art

[0002] There are many types of engineering inspections, and the inspection categories vary depending on the specific engineering project. For example, for ordinary asphalt pavement, it is necessary to drill and sample cores after the pavement has completely cooled down (usually the day after paving the asphalt) to detect the compaction of the pavement.

[0003] For example, a Chinese patent document with publication number CN216116840U discloses a coring machine, which includes a base frame, universal wheels connected to the four corners of the base frame, fixed rods connected to both sides of the top of the base frame, a lifting structure slidably connected to the fixed rod, a coring barrel movably screwed to the bottom of the lifting structure, and protective components are provided on both sides of the base frame. The protective components include a vertical plate fixed to the base frame, an electric slide rail is provided on the vertical plate, an electric slider is slidably connected to the electric slide rail, an electric push rod is connected to one side of the electric slider, a protective cover is provided at one end of the electric push rod, the electric push rod and the protective cover are connected by a connector, and the protective cover is adapted to the coring barrel.

[0004] In existing coring machines, universal wheels are installed at the four corners of the base frame to facilitate movement. However, this structure in which the universal wheels are fixedly installed on the base frame has the following shortcomings in actual use: when the coring machine is working, the best coring effect is achieved by drilling into the road surface in the vertical direction, that is, the drill barrel can drill downward in the vertical direction. However, in existing coring machines, the entire coring machine is supported by universal wheels, and the universal wheels and the frame are rotatably mounted via bearings. After a certain period of use, the bearing structure of the universal wheels is prone to wear or even damage, which will cause the coring machine to shake and deflect during the drilling process. Therefore, in order to solve the above problems, the road coring device of the present application is proposed. Utility Model Content

[0027] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0028] like Figures 1 to 4 As shown, a road coring device 10 includes a machine base 100, a drill bit 200 and a plurality of support members 300. The drill bit 200 is rotatably arranged on the machine base 100 along the vertical direction. The support members 300 are spaced apart at the bottom of the machine base 100. The support members 300 include a foot 310, a slide 320, a support wheel 330 and a clamping block 340. The foot 310 is arranged on the machine base 100 and extends from the bottom surface of the machine base 100. A sliding hole 311 is provided in the foot 310, and a guide hole 311 is provided on the outer side of the foot 310. The guide hole 312 is connected to the sliding hole 311, the slide 320 is adaptively slidably set in the sliding hole 311, the support wheel 330 is rotatably set on the lower side of the slide 320, the block 340 is slidably set on one side of the slide 320, and the block 340 is passed through the guide hole 312 to extend to the outside of the foot 310. The block 340 is used to slide along the guide hole 312 to make the slide 320 rise and fall and slide along the sliding hole 311, so that the support wheel 330 is retracted into the sliding hole 311 or extends from the bottom end of the sliding hole 311.

[0029] It should be noted that the support members 300 are installed at intervals on the bottom of the base 100. In one embodiment, four support members 300 are installed, located at the four corners of the bottom of the base 100. Furthermore, among the support members 300, a foot 310 is fixedly installed on the bottom of the base 100, wherein the foot 310 extends from the bottom side of the base 100. A sliding hole 311 is defined vertically in the foot 310, and a guide hole 312 is defined on the outer side of the foot 310, which communicates with the sliding hole 311. A slide 320 is slidably mounted within the sliding hole 311, and a support wheel 330 is rotatably mounted at the bottom of the slide 320 via a bearing. Thus, as the slide 320 rises and falls and slides within the sliding hole 311, the support wheel 330 can be retracted into the sliding hole 311 or extended from the bottom of the sliding hole 311. Furthermore, a clamping block 340 is mounted in a lateral sliding manner within the slide 320, with one end of the clamping block 340 extending through the guide hole 312 to the outside of the foot 310. Thus, by changing the position of the clamping block 340 within the guide hole 312, it is possible to change whether the support wheel 330 is retracted into the slide hole 311 or extended from the bottom of the slide hole 311. When the support wheel 330 is retracted into the slide hole 311, the foot 310 directly contacts the road surface, allowing the drill bit 200 to perform coring operations stably and reliably. When the support wheel 330 is extended from the bottom of the slide hole 311, the foot 310 is away from the road surface, and the device is now in a state of free movement. In this way, through the provision of each support members 300, the equipment can stably perform coring operations or move as needed, so that the support wheel 330 will not always be subjected to the vibration and pressure brought by the drill bit 200, thereby avoiding damage to the support wheel 330 and ensuring that the drill bit 200 can perform coring operations in the vertical direction.

[0030] like Figure 2 As shown, in one embodiment, the guide hole 312 includes a transverse hole groove 3121 and a vertical hole groove 3122 that are interconnected. When the blocking block 340 is located in the transverse hole groove 3121, the support wheel 330 extends from the bottom end of the sliding hole 311. When the blocking block 340 is located in the vertical hole groove 3122, the support wheel 330 retracts into the sliding hole 311.

[0031] It should be noted that the horizontal hole groove 3121 and the vertical hole groove 3122 form an L-shaped structure. When the clamping block 340 is located in the horizontal hole groove 3121, the support wheel 330 extends from the bottom of the slide hole 311. At this time, the clamping block 340 is clamped by the inner side wall of the horizontal hole groove 3121, so that the support wheel 330 remains stably extended from the slide hole 311. When the clamping block 340 is located in the vertical hole groove 3122, the support wheel 330 is stably retracted into the slide hole 311.

[0032] like Figure 2As shown, in one embodiment, the guide hole 312 further includes a limiting groove 3123 , and the limiting groove 3123 is located on the end of the horizontal hole groove 3121 away from the vertical hole groove 3122 .

[0033] It should be noted that, in order to ensure that the support wheel 330 stably extends from the bottom of the sliding hole 311 when the clamping block 340 is located in the transverse hole 3121 and does not accidentally slide into the vertical hole 3122, a limiting groove 3123 is provided at the end of the transverse hole 3121 away from the vertical hole 3122. Specifically, the limiting groove 3123 is located on the upper inner wall of the transverse hole 3121. In this way, under the action of the base 100's own weight, the clamping block 340 is stably accommodated in the limiting groove 3123, that is, the clamping block 340 is located in the transverse hole 3121.

[0034] like Figure 2 As shown, in one embodiment, a sliding groove 321 is opened on the sliding seat 320 along the horizontal direction, and one end of the block 340 is slidably disposed in the sliding groove 321.

[0035] It should be noted that to ensure that the block 340 can slide stably along the slide 320, a sliding groove 321 is formed in the side wall of the slide 320 in a transverse direction, and one end of the block 340 is slidably installed in the sliding groove 321. In one embodiment, the sliding groove 321 has a T-shaped cross-section. This allows the block 340 to slide reliably and stably along the sliding groove 321.

[0036] like Figure 2 As shown, in one embodiment, the support member 300 further includes a spring 350, which abuts against the inner side walls of the block 340 and the slide groove 321 respectively. The spring 350 is used to push the block 340 so that the block 340 has a tendency to slide from the vertical hole groove 3122 into the horizontal hole groove 3121.

[0037] Thus, under the elastic thrust of the spring 350, the clamping block 340 has a tendency to slide into the transverse slot 3121. Thus, when the clamping block 340 is located in the vertical slot 3122, one end of the device is lifted out of the slot and the clamping block 340 is stepped on. When the clamping block 340 is located in the transverse slot 3121, the clamping block 340 is pushed up by the spring 350 and slides the transverse slot 3121 away from one end of the vertical slot 3122. Thus, under the cooperative action of the spring 350 and the limiting slot 3123, the support wheel 330 is stably maintained in a state of extending out of the sliding hole 311.

[0038] like Figure 1As shown, in one embodiment, a handle 410 is provided at one end of the base 100 away from the drill bit 200. Thus, the handle 410 facilitates the user to apply thrust to the base 100 or to lift either end of the base 100 to adjust the support wheel 330 to retract into the slide hole 311 or to extend from the bottom end of the slide hole 311.

[0039] like Figure 1 As shown, in one embodiment, a reinforcement rod 420 is further provided between the handle 410 and the base 100. Thus, the structural strength between the handle 410 and the base 100 can be enhanced by installing the reinforcement rod 420. In one embodiment, two reinforcement rods 420 are provided, one on each side of the handle 410.

[0040] like Figure 1 As shown, in one embodiment, a guide rod 510 is provided on the machine base 100 , a lifting plate 520 is slidably provided on the guide rod 510 , a rotary driving member 530 is provided on the lifting plate 520 , and the drill bit 200 is provided on the output shaft of the rotary driving member 530 .

[0041] It should be noted that two guide rods 510 are provided, and the axes of the two guide rods 510 are installed in parallel. The lifting plate 520 is slidably mounted on the two guide rods 510, so that the lifting plate 520 can stably move up and down along the guide rods 510. The rotary drive member 530 is mounted on the lifting plate 520. For example, the rotary drive member 530 can be a motor or an engine driven by gasoline or diesel. The rotary drive member 530 is used to drive the drill bit 200 to continuously rotate.

[0042] The above-mentioned embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in the present invention can be understood to include but not be limited to locking and fixing with screws / screws and welding. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
