Description

TECHNICAL FIELD

[0001] The utility model belongs to the construction engineering survey technical field, and specifically relates to a construction engineering survey sampling device. BACKGROUND

[0002] In the field of rapidly developing construction engineering today, geological survey work is an important prerequisite for ensuring engineering quality and safety. As a key link for obtaining underground geological information, the accuracy and efficiency of survey sampling directly affect the planning, design and construction process of the entire project. However, the traditional construction engineering survey sampling device faces a series of severe challenges and problems in actual application.

[0003] In the past engineering practice, the survey sampling device used is equipped with a single drill bit for drilling operation. The design of this single drill bit will cause the temperature of the drill bit to rise sharply when it is continuously rubbed against the ground for a long time and a large amount of energy is lost during high-speed rotation. When the drill bit overheats, its physical properties will change significantly, such as reduced hardness and poor toughness. This not only leads to a significant decrease in drilling accuracy, making the quality of the obtained geological samples uneven and unable to accurately reflect the true geological conditions underground, but also seriously affects the efficiency and progress of drilling.

[0004] If the drill bit is used in an overheated state, high temperature may cause irreversible changes in the material structure of the drill bit, such as annealing and phase change, thereby accelerating the wear and damage of the drill bit and significantly shortening its service life. Frequent replacement of the drill bit not only increases the maintenance cost of the equipment, but also causes delays in the progress of the project due to downtime for replacing the drill bit.

[0005] To address the problem of drill bit overheating, the commonly used method in the past is to stop the equipment operation and let the drill bit cool down slowly in the natural environment. However, this method has obvious defects. First, the natural cooling process is usually slow and requires a lot of time, which undoubtedly leads to a significant reduction in work efficiency and unnecessarily prolongs the construction period of the entire project. Second, long-term downtime for cooling disrupts the original schedule of the project, causing delays in subsequent processes, and thus increasing the waste of resources in terms of manpower, material resources and time.

[0006] Therefore, we propose a construction engineering survey sampling device that enables the device to achieve rapid cooling and alternating use of the drill bit during drilling, greatly improving work efficiency and ensuring the continuity and stability of drilling operations. CONTENT OF THE UTILITY MODEL

[0007] The utility model discloses a construction engineering investigation sampling device, which can realize quick cooling and alternate use of a drill bit during drilling, greatly improves work efficiency and ensures continuity and stability of drilling operation.

[0008] The technical scheme adopted by the utility model is as follows:

[0009] A construction engineering investigation sampling device, comprising a support frame, a telescopic assembly is arranged on the support frame, a connecting plate is installed at the bottom of the telescopic assembly, and a drilling assembly is arranged at the bottom of the connecting plate.

[0010] The drilling assembly comprises a rotating assembly arranged at the bottom of the connecting plate, a hollow connecting rod is installed at the bottom of the rotating assembly, an opening is arranged at the bottom of the hollow connecting rod, a forced air cooling assembly is arranged in the hollow connecting rod, two symmetrical fixing plates are arranged at the bottom of the hollow connecting rod, a rotating assembly is arranged between the two fixing plates, a fixing sleeve is arranged on the rotating assembly, two triangular drill bits are arranged on the fixing sleeve, and a hollow heat-absorbing shell that is attached to the triangular drill bits is further arranged between the two fixing plates, and cooling liquid is arranged in the hollow heat-absorbing shell.

[0011] Further, the telescopic assembly comprises an electric telescopic rod arranged on the support frame, and the telescopic end of the electric telescopic rod is connected with the connecting plate.

[0012] Further, the rotating assembly comprises a high-speed motor arranged at the bottom of the connecting plate, and the output end of the high-speed motor is connected with the hollow connecting rod.

[0013] Further, the forced air cooling assembly comprises a support arranged in the hollow connecting rod, a first motor is arranged on the support, and a fan blade is installed at the output end of the first motor.

[0014] Further, a ventilation hole is formed in the outer side of the hollow connecting rod.

[0015] Further, the rotating assembly comprises a stepping motor arranged on the connecting plate, a rotating shaft is installed at the output end of the stepping motor, and the fixing sleeve is fixedly sleeved on the rotating shaft.

[0016] Further, the maximum length of the triangular drill bit is greater than the diameter of the hollow connecting rod.

[0017] Further, the hollow heat-absorbing shell is provided with a liquid inlet pipe.

[0018] The utility model achieves the following technical effects:

[0019] Firstly, the staff will place the whole device on the designated ground through the support frame, and ensure that the device will not shake or displace during the drilling process. Then, the telescopic assembly is controlled to drive the hollow connecting rod to move downward, so that the triangular drill bit gradually approaches the ground. At the same time, the rotating assembly is started to drive it to rotate at high speed. The rotation of the hollow connecting rod drives the bottom triangular drill bit to rotate together, so as to drill the ground to achieve the purpose of surveying and sampling. During the continuous rotation of the triangular drill bit, a large amount of heat will be generated due to the intense friction with the ground and the energy loss caused by high-speed rotation, which will cause the temperature of the drill bit to rise sharply. If the overheated drill bit is continued to be used, not only the accuracy and quality of the drilling will be affected, but also the material structure of the drill bit may change due to high temperature, thereby causing damage to the drill bit, shortening its service life and reducing the drilling effect. If the use is stopped when the drill bit is overheated and waiting for natural cooling, the work efficiency will be significantly reduced, the construction period of the whole project will be prolonged, and the construction cost will be increased. Therefore, when the triangular drill bit is overheated, the rotating assembly is started to drive the gear to rotate, thereby driving the fixed sleeve to rotate. The rotation of the fixed sleeve quickly exchanges the positions of the two triangular drill bits, so that the triangular drill bit which is not used and has a lower temperature is put into work, and the overheated drill bit enters between the two connecting plates and closely fits with the hollow heat-absorbing shell. At this time, the heat of the overheated triangular drill bit is quickly transferred to the hollow heat-absorbing shell in the form of heat conduction. The cooling liquid in the hollow heat-absorbing shell has good heat absorption performance and can absorb a large amount of heat to realize heat exchange, thereby reducing the temperature of the drill bit. At the same time, the air cooling assembly starts to work, and the fan or air duct inside the air cooling assembly accelerates the air flow inside the hollow connecting rod. The air flow formed by the air flow can take away the heat remaining on the triangular drill bit, further improve the cooling effect, and make the drill bit be cooled to a suitable temperature in a shorter time, so as to be used again. The device can realize the rapid cooling and alternating use of the drill bit during the drilling process, greatly improve the work efficiency, and ensure the continuity and stability of the drilling operation.

[0028] The drilling assembly comprises a rotating assembly arranged at the bottom of the connecting plate 2, the rotating assembly is installed at the bottom of the hollow connecting rod 3, the bottom of the hollow connecting rod 3 is provided with an opening, the hollow connecting rod 3 is provided with a forced air cooling assembly inside, and the bottom of the hollow connecting rod 3 is provided with two symmetrical fixed plates 4, a rotating assembly is arranged between the two fixed plates 4, the rotating assembly is provided with a fixed sleeve 5, two triangular drill bits 6 are arranged on the fixed sleeve 5, and a hollow heat absorption shell 7 is further arranged between the two fixed plates 4 and is attached to the triangular drill bits 6, and the hollow heat absorption shell 7 is provided with cooling liquid inside.

[0029] The telescopic assembly comprises an electric telescopic rod 8 arranged on the support frame 1, the telescopic end of the electric telescopic rod 8 is connected with the connecting plate 2, and the connecting plate 2 drives the triangular drill bits 6 to move up and down through the electric telescopic rod 8, so that drilling is facilitated.

[0030] Meanwhile, the rotating assembly comprises a high-speed motor 9 arranged at the bottom of the connecting plate 2, the output end of the high-speed motor 9 is connected with the hollow connecting rod 3, and the hollow connecting rod 3 is driven to rotate by the high-speed motor 9, so that the triangular drill bits 6 are rotated.

[0031] The model of the high-speed motor 9 is G030L130 high-speed alternating current main shaft motor.

[0032] The forced air cooling assembly comprises a support arranged inside the hollow connecting rod 3, the support is provided with a first motor 10, the output end of the first motor 10 is installed with a fan blade 11, the first motor 10 is fixed through the support, the fan blade 11 is driven to rotate by the first motor 10, so that air flow cools the triangular drill bits 6.

[0033] The hollow connecting rod 3 is provided with air holes 12 on the outer side, so that air can enter the hollow connecting rod 3 from the opening and then be discharged from the air holes 12, thereby forming air circulation.

[0034] The rotating assembly comprises a stepping motor 13 arranged on the connecting plate 2, and a rotating shaft is arranged at the output end of the stepping motor 13, and a fixing sleeve 5 is fixedly arranged on the rotating shaft, and the rotating shaft is driven to rotate by the stepping motor 13, so that the rotating shaft drives the fixing sleeve 5 to replace the two triangular drill bits 6.

[0035] The maximum length of the triangular drill bit 6 is greater than the diameter of the hollow connecting rod 3, so that the hole formed during rotation is greater than the hollow connecting rod 3, so that the hollow connecting rod 3 can easily enter.

[0036] It should be noted that: when replacing, the maximum length of rotation is greater than the length of the hole, but the rotating force of the stepping motor 13 and the special design of the triangular drill bit 6 make it easy to cut the soil for replacement.

[0037] The hollow heat-absorbing shell 7 is made of high-temperature-resistant heat-absorbing material, which can be ceramic material, so that it has high heat-absorbing performance.

[0038] It should be noted that: the hollow heat-absorbing shell 7 is provided with a liquid inlet pipe 14, and the cooling liquid enters through the liquid inlet pipe 14. The cooling liquid is a common cooling means in mechanical equipment. In the present application, although the cooling liquid absorbs heat, it can be quickly cooled through the action of the fan blade 11.

[0039] The working principle of the utility model is as follows: first, the staff places the whole device on the designated ground stably through the support frame 1, ensuring that the equipment does not shake or displace during the drilling process. Then, the telescopic assembly is controlled to drive the hollow connecting rod 3 to move downward, so that the triangular drill bit 6 gradually approaches the ground. At the same time, the rotating assembly is started to drive it to rotate at high speed. The rotation of the hollow connecting rod 3 drives the bottom triangular drill bit 6 to rotate together, thereby drilling the ground to achieve the purpose of surveying and sampling. During the continuous rotation of the triangular drill bit 6, a large amount of heat is generated due to the intense friction with the ground and the energy loss caused by high-speed rotation, resulting in a sharp rise in the temperature of the drill bit. If the overheated drill bit is continued to be used when the temperature of the drill bit exceeds a certain threshold, not only will it affect the accuracy and quality of the drilling, but also it may cause changes in the material structure of the drill bit due to high temperature, thereby causing damage to the drill bit, shortening its service life and reducing the drilling effect. If the use is stopped when the drill bit is overheated and waiting for natural cooling, the work efficiency will be significantly reduced, the construction period of the whole project will be prolonged, and the construction cost will be increased. Therefore, when the triangular drill bit 6 is overheated, the rotating assembly is started to drive the gear to rotate, thereby driving the fixed sleeve 5 to rotate. The rotation of the fixed sleeve 5 rapidly exchanges the positions of the two triangular drill bits 6, so that the triangular drill bit 6 that has not been used and has a lower temperature is put into work, while the overheated drill bit enters between the two connecting plates 2 and closely adheres to the hollow heat-absorbing shell 7. At this time, the heat of the overheated triangular drill bit 6 is rapidly transferred to the hollow heat-absorbing shell 7 in the form of heat conduction. The cooling liquid in the hollow heat-absorbing shell 7 has good heat absorption performance and can absorb a large amount of heat to achieve heat exchange, thereby reducing the temperature of the drill bit. At the same time, the air cooling assembly starts to work, and the fans or ventilation ducts inside the air cooling assembly accelerate the air flow inside the hollow connecting rod 3. The air flow formed by the air flow can carry away the residual heat on the triangular drill bit 6, further improving the cooling effect, so that the drill bit can be cooled to an appropriate temperature in a shorter time for reuse. The device enables the equipment to realize rapid cooling and alternating use of the drill bit during the drilling process, greatly improving the work efficiency and ensuring the continuity and stability of the drilling operation.

[0040] The above is only the preferred embodiment of the utility model, and it should be noted that those skilled in the art can make several improvements and refinements without departing from the principle of the utility model, and these improvements and refinements should also be considered within the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
