Description

Technical Field

[0001] This utility model relates to the technical field of sampling devices, specifically a sampling device for civil engineering surveys. Background Technology

[0002] Geotechnical investigation refers to the investigation, analysis, and evaluation of the geological and environmental characteristics and geotechnical engineering conditions of a construction site according to the requirements of a construction project. During the geotechnical investigation, it is necessary to ascertain the structure, formation age, origin, soil type, and burial distribution of the foundation soil and rock layers, thereby providing a reference for the site selection of the project.

[0003] Now, when sampling soil and rock, it is necessary to use a soil and rock exploration sampling device.

[0004] In related technologies, please refer to Chinese Patent No. CN215640222U, which specifically discloses a geotechnical investigation and sampling device for civil engineering. When using this geotechnical investigation and sampling device, a moving mechanism first moves the device to the sampling location, then a fixing mechanism secures the two base plates. Next, the motor is started, driving the turntable to rotate. Since the cover is detachably connected to the turntable and rotating head via a disassembly and assembly mechanism, the rotation of the turntable causes the cover and rotating head to rotate simultaneously. Simultaneously, the hydraulic cylinder is activated, causing it to retract. The retraction of the hydraulic cylinder moves the top plate downwards, which in turn moves the rotating head and cover downwards. After the rotating head drills into the soil, a spiral guide plate pulls the soil upwards. Simultaneously, the soil and rock on the spiral guide plate are stored by the obstruction of the casing. After sampling is completed, the motor is stopped and the hydraulic cylinder is started to rise, causing the top plate to move upward. The upward movement of the top plate drives the rotor and casing to move upward, finally removing the soil and rock layer. After the soil and rock layer is removed, the casing and turntable are separated by the disassembly and assembly mechanism. Then, the casing is slowly moved downward, which slowly leaks out the soil layer stored in the spiral guide plate and casing. Each layer of soil that leaks out is collected, thus achieving soil layer classification and sampling. The stabilizing mechanism makes the up and down movement of the top plate more stable.

[0005] The applicant found that the above-mentioned geotechnical sampling device for civil engineering has shortcomings: although it can classify and sample soil layers, it is necessary to separate the cover from the turntable through a disassembly and assembly mechanism, and then slowly move the cover downwards. This allows the soil layers stored in the spiral guide plate and the cover to slowly leak out, and each layer of soil that leaks out is collected. This can achieve classified sampling of soil layers, but the operation is cumbersome. In addition, the cover needs to be rotated to be introduced into the soil during sampling. Since the cover does not have a good limiting and guiding structure, the stability during sampling is reduced.

[0006] In view of this, this technical solution proposes a civil engineering survey and sampling device to better solve the problems mentioned above. Utility Model Content

[0007] The technical solution adopted by this utility model is as follows: a civil engineering survey and sampling device includes a support frame, foot pedals are fixed below the support frame, a guide plate is fixed on the lower inner side of the support frame, and a guide groove is opened inside the guide plate. A movable frame is slidably installed on the inner side of the support frame, and a hydraulic cylinder is installed inside the upper part of the support frame, and the extended end of the hydraulic cylinder is connected to the top of the movable frame.

[0008] A rotating platform is rotatably mounted inside the lower part of the movable frame. A motor is installed inside the movable frame, and the output end of the motor is connected to the rotating platform. A sampling cylinder is detachably installed at the bottom of the rotating platform, and a sampling blade is fixed below the sampling cylinder. A sampling port is opened inside the sampling cylinder for layered sampling inside the sampling cylinder.

[0009] In a preferred embodiment, the support frame has a U-shaped structure, with a handrail on the upper left side and casters on both the front and rear sides of the lower left side of the support frame, which are used to move the support frame in position in conjunction with the handrail.

[0010] In a preferred embodiment, a rivet runs through the inside of the foot pedal, and the rivet is fixed at the sampling position to position the support frame and the foot pedal.

[0011] In a preferred embodiment, the top of the foot pedal is provided with anti-slip texture.

[0012] In a preferred embodiment, the inner side of the support frame is provided with grooves at opposite positions, and a slider connected to the movable frame for limiting and guiding the movable frame is movably inserted into the groove.

[0013] In a preferred embodiment, the rotating table and the sampling cylinder are installed by bolts and flanges. The outer diameters of the sampling cylinder and the sampling cutter head are the same, and the outer diameters of the sampling cylinder and the sampling cutter head are adapted to the inner diameter of the guide groove.

[0014] In a preferred embodiment, the sampling ports may be linearly or staggered inside the sampling tube.

[0015] In a preferred embodiment, a cleaning port is provided at the top of the inside of the sampling tube, and a sealing cap is threadedly connected to the inside of the cleaning port. An operating plate for rotating the sealing cap is fixed to the top of the sealing cap.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates more stable sampling operations through the sampling tube, and the internal layered sampling operation of the sampling tube is more convenient, without the need for disassembly, saving manpower and increasing work efficiency.

[0017] 1. In this utility model, the support frame can be moved to the sampling position by the cooperation of the handrail and the universal wheel. The foot pedal can be fixed in the sampling position by the rivet. The motor and hydraulic cylinder are started. At this time, the hydraulic cylinder drives the moving frame and the sampling cylinder to move downward. At the same time, the guide groove can limit and guide the sampling cylinder. Under the action of the motor, the rotating table, the sampling cylinder and the sampling cutter head are rotated. At this time, the sampling cylinder can be introduced into the soil layer for sampling. After the sampling is completed, the sampling cylinder is pulled out of the soil layer by the hydraulic cylinder. At this time, different soil layers can be sampled through the sampling port.

[0018] 2. In this utility model, when it is necessary to remove all the soil layer inside the sampling tube, the sampling tube can be tapped. At this time, the coating inside the sampling tube can be removed. When the coating inside the sampling tube is firm and cannot be removed, the sampling tube can be disassembled from under the rotating table. Then, the sealing cover can be removed from the inside of the cleaning port through the operating plate. The soil layer inside the sampling tube can be pushed out using tools.
