Description

Technical Field

[0001] This utility model relates to the field of highway inspection technology, and in particular to a highway inspection core sampling machine. Background Technology

[0002] A highway core drilling machine is a specialized piece of equipment used to drill cylindrical core samples from asphalt or concrete pavements, bridges, tunnels, and other structures. It is mainly used to test key indicators of materials such as density, thickness, strength, and compaction.

[0003] In existing highway coring machines, drill bits are typically installed using threaded connections or bolts, resulting in a cumbersome and time-consuming disassembly process. This is especially problematic in environments requiring frequent drill bit changes (such as sampling rock layers of varying hardness or mixed materials), where operators must repeatedly tighten or loosen bolts using specialized tools, significantly reducing work efficiency. Furthermore, traditional fixing methods are prone to thread seizing or bolt loosening due to vibration, increasing maintenance difficulty and potentially affecting sampling accuracy. Therefore, there is an urgent need to design a device that enables rapid disassembly. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a highway inspection core sampling machine, including a fixing plate, wherein a disassembly assembly is provided on the lower side of the fixing plate.

[0006] In a preferred embodiment, the disassembly assembly includes a connecting sleeve, a locking block slidably disposed inside the connecting sleeve, two locking grooves formed on the outer surface of the locking block, a spring fixedly sleeved on the outer surface of the connecting sleeve, a sliding sleeve fixed to the other end of the spring, the sliding sleeve slidably disposed on the outer surface of the connecting sleeve, and two ball bearings embedded inside the connecting sleeve.

[0007] The technical effect of adopting the above-mentioned further solution is that the ball can be fixed in the groove inside the connecting sleeve by the locking of one end of the sliding sleeve, and then the ball can be stably locked in the groove on the locking block, thereby achieving the fixation of the drill bit.

[0008] In a preferred embodiment, the outer surface of the sliding sleeve is provided with anti-slip grooves.

[0009] The technical effect of adopting the above-mentioned further solution is that by setting anti-slip grooves, the operator's hand can be prevented from slipping, thus improving the disassembly efficiency.

[0010] In a preferred embodiment, a rubber pad is fixedly installed inside the connecting sleeve.

[0011] The technical effect of adopting the above-mentioned further solution is that by setting a rubber pad inside the connecting sleeve, the friction between the locking block and the connecting sleeve can be reduced, thereby reducing the wear of the device and improving the service life of the device.

[0012] In a preferred embodiment, a limiting block is fixedly installed inside the connecting sleeve, and a sliding groove is formed on the outer surface of the locking block.

[0013] The technical effect of adopting the above-mentioned further solution is that when installing the locking block, the limiting block needs to be engaged with the slide groove, thereby fixing the locking block a second time and improving the stability of the drill bit.

[0014] In a preferred embodiment, a motor is fixedly mounted on the upper side of the fixing plate, and the output end of the motor is fixedly mounted on one side of the connecting sleeve.

[0015] The technical effect of adopting the above-mentioned further solution is that the connecting sleeve is driven by a motor, thereby realizing the rotation of the drill bit for drilling.

[0016] In a preferred embodiment, a drill bit is fixedly installed at the other end of the block, a rectangular groove is provided at one end of the drill bit, a push plate is slidably disposed inside the drill bit, and one end of the push plate is threadedly installed inside the drill bit.

[0017] The technical effect of adopting the above-mentioned further solution is that when the material is stuck in the drill bit after drilling, the push plate can be manually rotated and moved downward along the drill bit, thereby pushing out the material inside the drill bit.

[0018] In a preferred embodiment, a plurality of diamond blocks are fixedly mounted on the other end of the drill bit.

[0019] The technical effect of adopting the above-mentioned further solution is that by fixing multiple diamond blocks at the bottom of the drill bit, it is possible to quickly drill holes in the road surface.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In use, the sliding sleeve needs to be manually pulled upwards first. The sliding sleeve will compress the spring, and the other end of the sliding sleeve will no longer fix the ball. At this time, the ball can move in the slot in the connecting sleeve. Then, the locking block can be manually rotated to drive the sliding groove on the locking block to move along the limiting block, and then the locking block can be pulled out, thereby realizing the quick disassembly of the drill bit.

The sliding sleeve 103 will then compress the spring 102. The other end of the sliding sleeve 103 will no longer fix and limit the ball 104. At this time, the ball 104 can move in the slot in the connecting sleeve 101. Then manually rotate... The movable locking block 106 drives the sliding groove on the locking block 106 to move along the limiting block 105, thereby pulling out the locking block 106 and realizing the quick disassembly of the drill bit 201. The locking block 106 can be fixed again by the engagement between the limiting block 105 and the sliding groove 108, thereby improving the stability of the device. When the material is stuck in the drill bit 201 after drilling, the push plate 202 is manually rotated and moves downward along the drill bit 201, thereby pushing out the material inside the drill bit 201.
