Description

Technical Field

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

[0002] In municipal inspections, to prevent shoddy workmanship during road construction, it is necessary to conduct relevant tests on the road surface after completion. Some key data require road sampling. In addition, to measure the thickness of the concrete road pouring, it is necessary to drill core samples from the road. Therefore, core drilling machines have been developed and are widely used in municipal inspection centers across the country.

[0003] Existing coring equipment used for municipal road maintenance and inspection typically uses a complex and tightly secured connection between the coring cylinder and the main body, such as multiple bolts. In practice, after coring, the cylinder needs to be disassembled to extract the core sample for subsequent testing and analysis, as well as for cleaning and maintenance. However, the inconvenience of disassembling the cylinder consumes significant time and manpower, impacting the efficiency of municipal road maintenance and inspection. Therefore, we are introducing a new coring equipment for municipal road maintenance and inspection. Utility Model Content

[0004] The main objective of this invention is to provide a core sampling device for municipal road maintenance and testing, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A core sampling device for municipal road maintenance and inspection includes a mobile base. A lifting mechanism is fixedly installed on the upper right side of the mobile base. An installation frame is installed inside the lifting mechanism. A motor is fixedly installed on the upper end of the installation frame. A connecting block is fixedly installed on the output end of the motor via a rotating rod. An embedding groove is opened at the lower end of the connecting block. A core sampling mechanism is engaged inside the embedding groove. Limiting grooves are opened at the middle of the front end and the middle of the rear end of the connecting block. A dust suppression mechanism is fixedly installed on the upper front part of the mobile base. A control box is fixedly installed on the upper rear part of the mobile base. A push rod is fixedly connected to the left end of the mobile base.

[0007] Preferably, the core extraction mechanism includes a fitting block, a core extraction cylinder is fixedly installed at the lower end of the fitting block, a linkage groove is provided in the front and rear inner parts of the fitting block, a spring is fixedly connected to the inner wall of the adjacent grooves of the two linkage grooves, a linkage block is fixedly connected to the end of the two springs away from the inner wall of the linkage groove, and a limit block is fixedly connected to the end of the two linkage blocks away from the springs.

[0008] Preferably, the fitting block is engaged with the embedding groove, and the two linkage blocks are respectively movably connected to the inner walls of the two linkage grooves.

[0009] Preferably, the two limiting blocks are respectively inserted and engaged with the two limiting slots, and the two limiting blocks are respectively movably connected with the two linkage slots.

[0010] Preferably, the dust suppression mechanism includes a water tank, an inlet fixedly connected to the upper end of the water tank, a water pump fixedly installed at the lower right end of the water tank, a spray pipe fixedly installed at the output end of the water pump, a fixing sleeve fixedly connected to the outer surface of the spray pipe, and a fixing rod fixedly connected to the rear of the outer surface of the fixing sleeve.

[0011] Preferably, the lower end of the water tank is fixedly connected to the movable seat, and the rear end of the fixed rod is fixedly connected to the lifting mechanism.

[0012] Preferably, the spray end of the water spray pipe is set at an inclined angle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By setting up a core sampling mechanism, two limiting blocks are pressed into the linkage groove, causing them to slide into the two linkage grooves and compress the springs. Then, the fitting block above the core sampling cylinder is engaged from the bottom of the connecting block into the embedding groove. The two limiting blocks automatically pop out into their corresponding limiting grooves under the reset of the springs, which facilitates the quick installation and disassembly of the core sampling cylinder. This allows operators to quickly connect or separate the core sampling cylinder from the main body of the equipment. During installation, no complicated calibration and tightening operations are required. It can be quickly positioned and installed, shortening the preparation time before each core sampling. After core sampling, it can be easily disassembled, followed by core sample processing and preparation for the next core sampling. This increases the number of core samplings per unit time, making the entire inspection workflow more efficient and enabling the inspection of large areas of roads to be completed in a shorter time.

[0015] 2. By setting up a dust suppression mechanism, when the core sampler rotates at high speed and drills into the road surface, it generates intense friction with the road material, accumulating a large amount of heat in a short time. This heat may cause the core sampler to deform and be damaged due to overheating, affecting its service life. By starting the water pump, water in the water tank is sprayed onto the core sampler through the water spray pipe. The water flow can quickly remove the heat generated by friction, keeping the temperature of the core sampler and the road material within a reasonable range. In addition, during the process of the road material being drilled and broken by the core sampler, a large amount of fine dust is generated. This dust permeates the working environment, not only causing serious air pollution and affecting the surrounding air quality, but also posing a threat to the health of the operators. Long-term inhalation may cause respiratory diseases. Spraying water can cause the dust particles to absorb moisture, increase their weight, and settle quickly, reducing the dust content in the air, creating a cleaner and safer working environment, protecting the occupational health of the operators, and reducing pollution to the surrounding environment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A core sampling device for municipal road maintenance and inspection includes a mobile base 1. A lifting mechanism 2 is fixedly installed on the upper right side of the mobile base 1. An installation frame 3 is installed inside the lifting mechanism 2. A motor 4 is fixedly installed on the upper end of the installation frame 3. A connecting block 5 is fixedly installed on the output end of the motor 4 via a rotating rod. An embedding groove 6 is opened at the lower end of the connecting block 5. A core sampling mechanism 7 is engaged and connected inside the embedding groove 6. Limiting grooves 8 are opened at the middle of the front end and the middle of the rear end of the connecting block 5. A dust suppression mechanism 9 is fixedly installed on the upper front middle part of the mobile base 1. A control box 10 is fixedly installed on the upper rear middle part of the mobile base 1. A push rod 11 is fixedly connected to the left end of the mobile base 1.

[0026] In this embodiment, the core extraction mechanism 7 includes a fitting block 71, and a core extraction cylinder 72 is fixedly installed at the lower end of the fitting block 71. The fitting block 71 has a linkage groove 73 in both the front and rear inner parts. The inner walls of the two adjacent linkage grooves 73 are fixedly connected to springs 74. The ends of the two springs 74 away from the inner walls of the linkage grooves 73 are fixedly connected to linkage blocks 75. The ends of the two linkage blocks 75 away from the springs 74 are fixedly connected to limit blocks 76. The fitting block 71 is engaged with the embedded groove 6. The two linkage blocks 75 are movably connected to the inner walls of the two linkage grooves 73 respectively. The two limit blocks 76 are interlocked with the two limit grooves 8 respectively, and the two limit blocks 76 are movably connected to the two linkage grooves 73 respectively.

[0027] The above scheme involves pressing two limiting blocks 76 into the linkage groove 73, causing the two limiting blocks 76 to slide into the two linkage grooves 73 respectively and compress the spring 74. Then, the fitting block 71 above the core tube 72 is inserted into the embedding groove 6 from the bottom of the connecting block 5. The two limiting blocks 76 automatically pop out into the corresponding limiting grooves 8 under the reset of the spring 74, thus facilitating the quick installation and removal of the core tube 72.

[0028] In this embodiment, the dust suppression mechanism 9 includes a water tank 91, an inlet 92 fixedly connected to the upper end of the water tank 91, a water pump 93 fixedly installed at the lower right end of the water tank 91, a spray pipe 94 fixedly installed at the output end of the water pump 93, a fixing sleeve 95 fixedly connected to the outer surface of the spray pipe 94, a fixing rod 96 fixedly connected to the rear of the outer surface of the fixing sleeve 95, the lower end of the water tank 91 fixedly connected to the movable seat 1, the rear end of the fixing rod 96 fixedly connected to the lifting mechanism 2, and the spray end of the spray pipe 94 is set at an inclined angle.

[0029] The above solution involves starting the water pump 93, which sprays water from the water tank 91 through the spray pipe 94 onto the core sampler 72. The water flow can quickly carry away the heat generated by friction, keeping the temperature of the core sampler 72 and the road surface material within a reasonable range.

[0030] It should be noted that this utility model is a core sampling device for municipal road maintenance and inspection. During use, by pressing the two limiting blocks 76 in the linkage groove 73, they slide along the linkage groove 73 and compress the spring 74. Then, the fitting block 71 at the top of the core sampling cylinder 72 is inserted into the embedding groove 6 at the bottom of the connecting block 5. At this time, under the restoring force of the spring 74, the two limiting blocks 76 will automatically spring into the corresponding limiting groove 8, thereby realizing the quick installation and convenient disassembly of the core sampling cylinder 72. This allows operators to quickly connect or separate the core sampling cylinder 72 from the main body of the equipment without complicated calibration and tightening steps. The installation process is simple and quick, shortening the preparation time before core sampling. After completing the core sampling task, the core sampling cylinder 72 can also be easily disassembled for immediate core sample processing and preparation for the next core sampling, thereby improving the core sampling efficiency per unit time and accelerating the entire inspection workflow. In addition, when the core sampling cylinder 72 is drilling into the road... When the core sampler is drilling into the road surface, it will generate intense friction with the road material, rapidly accumulating a large amount of heat. If this heat is not dissipated in time, it may cause the core sampler 72 to deform and be damaged due to overheating, shortening its service life. To solve this problem, the water pump 93 can be started to spray water from the water tank 91 directly onto the core sampler 72 through the water spray pipe 94. The water flow can quickly remove the heat generated by friction, ensuring that the temperature of the core sampler 72 and the road material is kept within a safe range. At the same time, during the process of the core sampler 72 drilling into the road material, a large amount of fine dust will be generated. This dust will not only seriously pollute the working environment and affect air quality, but may also pose a potential threat to the health of the operators. Therefore, spraying water can cause the dust particles to absorb moisture, increase their weight and accelerate their settling, thereby reducing the dust content in the air, creating a cleaner and safer working environment for the operators, protecting their occupational health, and also reducing pollution to the surrounding environment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
