Description

Technical Field

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

[0002] After road paving, to ensure normal vehicle traffic, road testing is necessary, including checking parameters such as road smoothness, settlement, and compaction. A common method for testing road compaction is core sampling, which involves drilling a portion of the road surface using a core sampling device for testing. Additionally, core sampling is frequently required in bridge pile foundation construction to determine the concrete's setting condition and strength.

[0003] According to patent number CN219694584U, an engineering core sampling device includes a support, a lifting mechanism, a power mechanism, a drill barrel, and a dustproof component. The lifting mechanism is mounted on the support; the power mechanism is mounted on the lifting mechanism and drives its movement; the drill barrel is mounted on the power mechanism and drives its rotation; the dustproof component includes a connecting cylinder and a telescopic cylinder. The connecting cylinder is mounted on the support, and its first inner hole corresponds to the drill barrel. The telescopic cylinder is detachably connected to the connecting cylinder and has a second inner hole communicating with the first inner hole, allowing it to extend and retract along the lifting direction of the drill barrel. With this structure, the dustproof component, mounted on the support, is easy to carry and does not need to be carried separately. It also protects the drilling point from dust, preventing water splashing and interference with the normal operation of the lifting mechanism, and minimizes obstruction to the field of vision of construction personnel.

[0004] Although the above technical solution can complete the sampling of road core samples, in the field of road testing technology, the core samples taken outdoors are usually brought back indoors and core samples of different diameters are taken for testing. However, this device can only be used for outdoor sampling, the sampling method is limited, and when the core samples are sampled again indoors, not only can the core samples not be fixed, but it also makes sampling difficult. Utility Model Content

[0005] The purpose of this invention is to provide a core sampling device for road testing, which can not only achieve sampling both indoors and outdoors, improving its applicability, but also fix different sizes of core samples taken indoors, making it convenient to take samples again.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A core sampling device for road inspection includes a sampling device body. The sampling device body includes a fixed frame, a connecting frame slidably connected between the left and right sides of the front end of the fixed frame, a drive motor installed at the lower end of the connecting frame, and a first electric push rod installed at the rear end of the outer wall of the connecting frame and the upper end of the inner wall of the fixed frame. A fixing buckle is provided at the lower end of the outer wall of the drive motor power output shaft. A sampling drill bit is detachably connected to the fixing buckle. T-shaped fixing grooves are provided on the lower left and right sides of the front end of the fixed frame. Each fixing groove is slidably connected to a fixing component for fixing the core sample. The fixing component includes a fixing block, a T-shaped sliding groove opened on one side of the outer wall of the fixing block, a slider that slides along the length of the sliding groove and extends out of its upper opening, a positioning block provided on one side of the upper end of the slider, and a fixing plate provided on one side of the positioning block in an arc shape.

[0008] The two fixing plates are arranged opposite each other. The inner wall of each fixing plate is provided with a number of fixing rods arranged in an array to increase the friction when fixing the sample core. The left and right sides of the inner wall of the fixing frame are equipped with second electric push rods that contact the corresponding positioning blocks and drive the corresponding sliders to slide. The water spray assembly and the storage battery are installed sequentially from front to back at the rear end of the bottom of the inner wall of the fixing frame. Handrails are provided on the left and right sides of the rear end of the bottom of the fixing frame. The upper end of the inner wall of the handrail is provided with a control panel. The drive motor, the first electric push rod, the second electric push rod, the water spray assembly and the storage battery are all electrically connected to the control panel.

[0009] By adopting the above technical solution, during use, the sampling device body is first moved to the outdoor location where sampling is needed and fixed. Then, the control panel on the handrail is operated, powered by the battery, to activate the drive motor and the first electric push rod. The first electric push rod extends, causing the connecting frame to slide the drive motor downwards. When the sampling drill bit approaches the sampling position, the drive motor drives the sampling drill bit to rotate at high speed while the first electric push rod gradually extends to assist in sampling, thus completing outdoor sampling. After sampling, the sample core is brought back indoors, and sampling can be performed again on the sample core. The process involves replacing the sampling drill bit with the appropriate size using the fixing buckle, then installing and fixing the two fixing components in the corresponding fixing slots. The second electric push rod operates synchronously according to the size of the sampling core, pushing the slider to slide closer together. The sampling core is then placed between the two fixing plates and fixed. Sampling can then be performed on the sampling core using the replaced sampling drill bit, enabling indoor sampling. For both outdoor and indoor sampling, the water spray component can be activated, reducing dust splashing and lowering the temperature of the sampling drill bit during sampling.

[0010] A further feature of this invention is that a plurality of rollers arranged in an array are rotatably connected to the bottom of the outer wall of the fixing frame.

[0011] By adopting the above technical solution, the sampling device body can be moved easily, so as to complete indoor and outdoor core sampling according to actual needs, thereby improving its flexibility of use.

[0012] A further feature of this invention is that each slider has a support block for placing the sample core at one end that is close to the other.

[0013] By adopting the above technical solution, the bearing block not only allows the sample core to be away from the ground for convenient sampling, but also facilitates the two fixing components to fix the sample core.

[0014] A further feature of this invention is that each positioning block has a U-shaped positioning buckle on the side away from the corresponding fixing plate, and one end of each second electric push rod has a positioning plate that slides and engages with the corresponding positioning buckle and is detachably connected to it.

[0015] By adopting the above technical solution, when the second electric push rod is working, the sliding block can be easily controlled to slide back and forth through the positioning buckle and positioning plate.

[0016] A further feature of this invention is that the water spray assembly includes a water storage tank, a water pump installed on the upper part of the outer wall of the water storage tank, an inlet pipe connected to the inlet of the water pump and extending to the bottom of the inner wall of the water storage tank, a T-shaped pipe installed at the outlet of the water pump, and a flexible outlet pipe connected to the upper part of the T-shaped pipe.

[0017] A further feature of this invention is that a connecting rod is provided between the rear ends of the two outer walls of the sliders, and a threaded hole is provided downward through the middle of the upper end of the outer wall of the connecting rod, and a fixing bolt for fixing the fixing component is threaded into the threaded hole.

[0018] By adopting the above technical solution, the connecting rod can not only install and fix the two fixing components on the fixing groove at the same time, but also fix them with fixing bolts to prevent the fixing components from sliding during the sampling process, thereby affecting the sampling of the sample core.

[0019] In summary, this utility model has the following beneficial effects:

[0020] Firstly, this utility model can not only realize sampling both indoors and outdoors, thus improving its applicability, but also, when sampling sample cores indoors, it can fix sample cores of different sizes that have already been sampled, making it convenient to sample again.

[0021] Secondly, the installation and disassembly of the fixing component and the fixing frame of this utility model are convenient, and the fixing component can be fixed simultaneously by means of connecting rod and fixing bolt, so as to avoid the shaking of the fixing component during the sampling process and affect the sampling.

[0022] Thirdly, the bearing block of this utility model not only allows the sample core to be away from the ground for convenient sampling, but also facilitates the two fixing components to fix the sample core and achieve fixation at different positions of the sample core.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0031] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0032] Example, refer to Figure 1-4 A core sampling device for road inspection includes a sampling device body 1. The sampling device body 1 includes a fixed frame 11, a connecting frame 12 that is slidably connected between the left and right sides of the front end of the fixed frame 11 and slides along its height direction, a drive motor 13 installed at the lower end of the connecting frame 12, and a first electric push rod 14 that is installed at the rear end of the outer wall of the connecting frame 12 and the upper end of the inner wall of the fixed frame 11. Four rollers 15 arranged in an array are rotatably connected to the bottom of the outer wall of the fixed frame 11. A fixing buckle 16 is provided at the lower end of the outer wall of the power output shaft of the drive motor 13. A sampling drill bit 17 is detachably connected to the fixing buckle 16. A T-shaped fixing groove 18 is provided on the lower left and right sides of the front end of the outer wall of the fixed frame 11. Each fixing groove 18 is slidably connected to a fixing component 19 for fixing the core sample.

[0033] The fixing component 19 includes a fixing block 2, a T-shaped slide groove 21 on one side of the outer wall of the fixing block 2, a slider 22 that slides along the length of the slide groove 21 and extends out of its upper opening, a positioning block 23 on one side of the upper end of the slider 22, and a fixing plate 24 on one side of the positioning block 23 that is arc-shaped. Each slider 22 has a bearing block 28 for placing a sample core at one end that is close to each other. The two fixing plates 24 are arranged opposite each other. The inner wall of each fixing plate 24 is provided with a number of fixing rods 29 arranged in an array to increase the friction when fixing the sample core. A connecting rod 25 is provided between the rear ends of the outer walls of the two sliders 22. A threaded hole 26 is opened downward through the middle of the upper end of the outer wall of the connecting rod 25. A fixing bolt 27 that cooperates with the fixing frame 11 and is used to fix the fixing component 19 is threaded into the threaded hole 26.

[0034] On both the left and right sides of the inner wall of the fixing frame 11, there is a second electric push rod 3 that contacts the corresponding positioning block 23 and is used to drive the corresponding slider 22 to slide. Each positioning block 23 has a U-shaped positioning buckle 31 on the side away from the corresponding fixing plate 24. One end of each second electric push rod 3 is provided with a positioning plate 32 that slides and engages with the corresponding positioning buckle 31 and is detachably connected to it. At the rear end of the bottom of the inner wall of the fixing frame 11, a water spray assembly 33 and a battery 39 are installed sequentially from front to back. The water spray assembly 33 includes a water tank 34. A water pump 35 is installed on the upper part of the outer wall of the water storage tank 34, an inlet pipe 36 is connected to the inlet of the water pump 35 and extends to the bottom of the inner wall of the water storage tank 34, a tee pipe 37 is installed at the outlet of the water pump 35, and a flexible outlet pipe 38 is connected to the upper end of the tee pipe 37. A handrail 4 is provided on the left and right sides of the bottom rear end of the fixing frame 11. A control panel 41 is provided on the upper part of the inner wall of the handrail 4. The drive motor 13, the first electric push rod 14, the water pump 35, the second electric push rod 3 and the battery 39 are all electrically connected to the control panel 41.

[0035] Usage: When in use, first move the sampling device body 1 to the outdoor sampling location using the rollers 15 and fix it. Then operate the control panel 41 on the handrail frame 4. Power is provided by the battery 39 to make the drive motor 13 and the first electric push rod 14 work. The first electric push rod 14 extends and the connecting frame 12 drives the drive motor 13 to slide down along the height of the fixed frame 11. When the sampling drill bit 17 approaches the sampling position, the drive motor 13 drives the sampling drill bit 17 to rotate at high speed while the first electric push rod 14 gradually extends to cooperate with sampling, thus completing the outdoor sampling work. After sampling, bring the sample core back indoors and perform sampling and testing on the sample core again. Replace the sampling drill bit 17 of the appropriate size using the fixing buckle 16. Then install the two fixing components 19 in the corresponding fixing slots 18 using the connecting rod 25 and rotate the fixing bolt 27 in the threaded hole 26 to make its lower end contact the fixed frame 11 to fix the fixing components 19.

[0036] When installing the fixing component 19, the positioning plate 32 on the second electric push rod 3 is engaged and fixed with the corresponding positioning buckle 31. Then, according to the size of the sample core, the two second electric push rods 3 work synchronously. The second electric push rods 3 push the slider 22 along the corresponding slide groove 21 through the fixing block 2, bringing them closer to each other. Then, the sample core is placed on the bearing block 28 between the two fixing plates 24. Next, the second electric push rods 3 extend to fix the sample core. The fixing rod 29 on the fixing plate 24 can improve the fixing effect of the sample core. Then, the sample core can be replaced. The sample drill bit 17 takes samples from the sample core, thus enabling indoor sampling. It also allows the two second electric push rods 3 to work separately, thereby achieving eccentric sampling. When sampling outdoors or indoors, the water spray assembly 33 can be activated and the positions of the two water outlet pipes 38 can be adjusted so that they can spray water at the corresponding positions. The water pump 35 draws water from the water storage tank 34 through the water inlet pipe 36, and then splits into two water paths through the three-way pipe 37 before flowing out through the water outlet pipe 38. Spraying water can not only reduce dust splashing, but also lower the temperature of the sampling drill bit 17 during sampling.

[0037] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
