Description

Technical Field

[0001] This utility model relates to the field of road sampling technology, and in particular to a loading and unloading device for a road coring machine. Background Technology

[0002] Core sampling machines are widely used equipment, especially in concrete structure inspection and road on-site inspection. Existing core sampling machines typically include an electric or fuel-powered power source and a core cylinder (i.e., a hollow drill bit used for core sampling) that is connected to the power source and can rotate at high speed around its own axis. The first end of the core cylinder is open for cutting the surface of the structure to be tested, and the second end is connected to the power source and connected to a cooling water pipe for cooling the core cylinder under high-speed rotation.

[0003] When using existing coring machines, the drill bit is first fixed to the machine, and then the coring process is performed at the desired location. This approach presents the following problems in actual operation:

[0004] 1. During the core retrieval process, the core retrieval machine will move downward and rotate to retrieve the core from the ground. After drilling, the core retrieval machine needs to be removed from the core retrieval site in order to retrieve the core sample that fell into the borehole. This makes it inconvenient to continue the drilling and core retrieval process.

[0005] 2. During the coring process, the drill bit diameter or length will be changed according to the coring requirements. However, the existing drill bits are generally connected to the coring machine body by screws, which is not convenient for quick installation of the drill bits in actual use. Utility Model Content

[0006] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0007] Specifically, the technical problem to be solved by this utility model is to provide a loading and unloading device for a road core sampling machine, so as to solve the technical problem that the current drilling equipment is inconvenient to quickly disassemble the drill bit, and the core sample is easy to get stuck at the drill bit, making it inconvenient to remove the core sample.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0009] A loading and unloading device for a road coring machine includes a coring frame, a quick-release mechanism fixedly installed on the top of the coring frame, and a lifting core drilling mechanism provided on the top of the coring frame away from the quick-release mechanism.

[0010] The quick-release mechanism includes an adjustment assembly, which includes a hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected to the top of the core-retrieving frame. A hydraulic rod is fixedly installed on the output end of the hydraulic cylinder via a piston. A connecting post is provided on the inner surface of the core-retrieving frame, and the top of the inner cavity of the connecting post is fixedly connected to the top of the hydraulic rod.

[0011] As an improved technical solution, the quick-release mechanism further includes a rotating assembly, which includes a connecting plate. The inner surface of the connecting plate is fixedly connected to the outer surface of the connecting column. A threaded rod is fixedly installed on the inner surface of the connecting plate. A first lifting frame is threadedly installed on the outer surface of the threaded rod. A rotating block is fixedly installed on the inner surface of the first lifting frame through a locking rod. A hexagonal locking block is rotatably installed on the inner surface of the rotating block. A drill bit is fixedly installed at the bottom end of the hexagonal locking block.

[0012] As an improved technical solution, the rotating assembly further includes a replacement turntable, the bottom of which is fixedly connected to the top of the connecting column, and a replacement handle is fixedly installed on the top of the replacement turntable.

[0013] As an improved technical solution, the lifting drill core mechanism includes a threaded column, a main gear is fixedly installed on the outer surface of the threaded column, a lifting turntable is fixedly installed on the top of the threaded column, and a lifting handle is fixedly installed on the top of the lifting turntable.

[0014] As an improved technical solution, the lifting drill core mechanism also includes a fixed frame, and a first driven gear is rotatably mounted on the bottom of the fixed frame via a rotating rod. The outer surface of the first driven gear meshes with the outer surface of the main gear.

[0015] As an improved technical solution, the lifting drill core mechanism further includes a second driven gear, the inner surface of which is fixedly connected to the outer surface of the threaded rod, and the outer surface of the second driven gear meshes with the outer surface of the first driven gear.

[0016] As an improved technical solution, the lifting core drilling mechanism further includes a connecting rod, the bottom end of which is fixedly connected to the top of the core-taking frame, a second lifting frame is slidably mounted on the outer surface of the connecting rod, the inner surface of the second lifting frame is threadedly connected to the outer surface of the threaded column, and a core drilling driver is fixedly mounted on the top of the second lifting frame.

[0017] As an improved technical solution, a rapid core-taking mechanism is fixedly installed on the inner surface of the drill bit. The rapid core-taking mechanism includes a squeezing plate, the outer surface of the squeezing plate is slidably connected to the inner surface of the drill bit, a top block is connected to the top of the squeezing plate, and a through hole is opened on the outer surface of the squeezing plate.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are:

[0019] 1. This utility model improves the speed and efficiency of core drilling by adding a design for quick installation and removal of drill bits. It utilizes the cooperation of hydraulic cylinders and hydraulic rods with connecting columns and connecting discs; the cooperation of connecting discs and threaded rods with the No. 1 lifting frame and rotating block; the cooperation of rotating block and hexagonal locking block with the core driver and drill bit; and the cooperation of changing turntables and changing handles with connecting discs and connecting columns. This allows for the rapid fixing of drill bits of different sizes onto the core driver, avoiding the need to move the core drilling machine and then remove the drill bit when changing drill bits in traditional core drilling machines, thus improving the speed and efficiency of drill bit changing.

[0020] 2. This utility model improves upon the design of quickly removing the core sample from the drill bit by using the drill bit and hexagonal clamping block in conjunction with the extrusion plate and top block. This allows the external rod to press the top block, which in turn causes the extrusion plate to remove the core sample from the drill bit, thus avoiding the problem of the core sample getting stuck in the drill bit and being difficult to remove.

[0034] Hydraulic cylinder 211 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0035] like Figure 1 and Figure 2 As shown, the quick-release mechanism 2 also includes a rotating component 22, which includes a connecting plate 221. The inner surface of the connecting plate 221 is fixedly connected to the outer surface of the connecting column 213.

A rotating block 224 is fixedly installed on the inner surface of the first lifting frame 223 by a locking rod. A hexagonal locking block 225 is rotatably installed on the inner surface of the rotating block 224. A drill bit 226 is fixedly installed at the bottom end of the hexagonal locking block 225.

[0036] like Figure 1 and Figure 2 As shown, the rotating assembly 22 also includes a replacement turntable 227, the bottom of which is fixedly connected to the top of the connecting post 213, and a replacement handle 228 is fixedly installed on the top of the replacement turntable 227.

[0038] like Figure 1 and Figure 2 As shown in the figure, the lifting core drilling mechanism 3 also includes a fixed frame 35. The bottom of the fixed frame 35 is rotatably mounted with a first driven gear 36 via a rotating rod. The outer surface of the first driven gear 36 meshes with the outer surface of the main gear 32.

[0039] like Figure 1 and Figure 2As shown in the figure, the lifting drill core mechanism 3 also includes a second driven gear 37, the inner surface of which is fixedly connected to the outer surface of the threaded rod 222, and the outer surface of the second driven gear 37 meshes with the outer surface of the first driven gear 36.

[0040] like Figure 1 and Figure 2 As shown, the lifting core drilling mechanism 3 also includes a connecting rod 38. The bottom end of the connecting rod 38 is fixedly connected to the top of the core frame 1. A second lifting frame 39 is slidably installed on the outer surface of the connecting rod 38. The inner surface of the second lifting frame 39 is threadedly connected to the outer surface of the threaded column 31. A core drilling driver 4 is fixedly installed on the top of the second lifting frame 39.

[0041] The core drive 4 consists of a motor, a rotating shaft, a clamping block, and a water inlet pipe. It can drive the drill bit 226 to rotate while simultaneously injecting water into the drill bit 226.

[0042] like Figure 1 and Figure 4 As shown, a quick core extraction mechanism 5 is fixedly installed on the inner surface of the drill bit 226. The quick core extraction mechanism 5 includes a pressing plate 51. The outer surface of the pressing plate 51 is slidably connected to the inner surface of the drill bit 226.

[0043] In operation, the operator first fixes multiple drill bits 226 onto the first lifting frame 223. The operator then pushes the core extractor to the designated position. The operator first rotates the change handle 228, which, through the change turntable 227, drives the connecting column 213 to rotate, moving the drill bits 226 below the core drive 4. Then, the hydraulic cylinder 211, through the hydraulic rod 212, moves the connecting column 213 upwards. The connecting column 213, through the threaded rod 222, moves the first lifting frame 223 upwards. The first lifting frame 223, through the drill bits 226, drives the hexagonal locking block 225 to engage with the output end of the core drive 4, enabling the core drive 4 to rotate the drill bits 226. Simultaneously, the second driven gear 37 meshes with the first driven gear 36. The operator then rotates the lifting handle 34, which, through the lifting turntable 33, drives the threaded rod 225 to rotate. The threaded column 31 rotates, and the threaded column 31 drives the first driven gear 36 to rotate through the main gear 32. The first driven gear 36 drives the threaded rod 222 to rotate through the second driven gear 37. The threaded rod 222 drives the drill bit 226 to move downward through the first lifting frame 223. When the lifting turntable 33 rotates, the lifting turntable 33 drives the second lifting frame 39 to move downward through the threaded column 31. The second lifting frame 39 drives the core drive 4 to move downward, so that the core drive 4 can move up and down synchronously with the drill bit 226. After the core drilling is completed, the core column is inside the drill bit 226. The user uses the quick release mechanism 2 to remove the drill bit 226. Then the user inserts the tang into the hexagonal locking block 225 and presses against the top block 52. The top block 52 drives the extrusion plate 51 to move inside the drill bit 226, so that the extrusion plate 51 pushes out the drilled material inside the drill bit 226.

Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
