Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a static probe penetration device, in particular to a double-oil cylinder guide rail type static probe penetration device. Background Art

[0002] As a method for in-situ soil testing in the field of geotechnical engineering technology, static penetration testing uses a feeding device to penetrate a probe rod with a probe at the bottom into the soil layer, and evaluates the basic physical and mechanical properties of the soil, such as the deformation modulus of the soil and the allowable bearing capacity of the soil, by measuring parameters such as penetration resistance and friction. According to the technical specifications for static penetration testing, the probe rod is required to maintain a continuous, stable and constant speed feed during the penetration of the soil layer. Traditional mechanical and hydraulic static penetration testing machines, due to the intermittent feeding method of a single cylinder group cylinder, usually have an obvious acceleration process at the beginning of a probe rod, and there is a pause between the two probe rods for a period of time, which is used for the return of the feeding mechanism and the addition of probe rods. In this way, the speed at which the probe rod penetrates the soil layer is not uniform, continuous and stable. At the beginning and end of each probe rod, the penetration speed does not meet the specification requirements, resulting in poor test data, which affects the acquisition of complete soil layer data.

[0003] For example, a hydraulic automatic rod clamp of a static penetration test machine disclosed in a Chinese patent document (application number: 201520453201.7) includes a base, a probe rod, a bracket and a lifting cylinder. The lifting cylinder can be operated by a reversing valve to drive the bracket to move up and down. The hydraulic automatic rod clamp of the static penetration test machine is arranged on the bracket, and the probe rod passes through the hydraulic automatic rod clamp. However, when the static penetration test machine is used to penetrate a long probe rod, the clamp is located at a high position, so the operation is inconvenient and the working stability is not high. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and proposes a double-cylinder guide rail static probe penetration device which is suitable for the penetration of long probe rods, is easy to operate, and works stably and reliably.

DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] like Figures 1 to 2 As shown, a double-cylinder guide rail static exploration penetration device comprises a cylinder fixing plate 1, both ends of which are vertically provided with cylinders 2, and is characterized in that the piston rods of the cylinders 2 are both arranged upward, and the upper ends of the two piston rods are respectively fixedly connected to the two ends of a horizontally arranged connecting plate 3, and a parallel lifting plate 4 is provided on the lower side of the connecting plate 3, and the two ends of the lifting plate 4 are fixedly connected to the connecting plate 3 through a push rod 5, and the upper and lower ends of the push rod 5 respectively pass through the connecting plate 3 and the lifting plate 4 and are fixedly connected through nuts, which has the advantages of firm connection and simple structure.

[0028] The static probe penetration device also includes a probe 6, which can vertically pass through the lifting plate 4. The lifting plate 4 is provided with a clamp 7 that can clamp the probe rod, and a guide mechanism 8 is provided between the two sides of the lifting plate 4 and the cylinder body of the oil cylinder 2. The guide mechanism 8 includes a bracket 8a fixedly connected to the two ends of the lifting plate 4, and two inclined and horizontally symmetrical brackets 8a are provided at both ends of the lifting plate 4. A roller 8c is axially fixed to the bracket 8a, and the roller 8c is abutted against the cylinder body of the corresponding oil cylinder 2 and the roller 8c can roll along the vertical direction of the cylinder body of the oil cylinder 2. The roller 8c is made of copper, which has good wear resistance and a long service life. As another method, the roller 8c is made of nylon material.

The adjustment structure includes a connecting sleeve 8d threadedly connected to the lifting plate 4. Two inclined and horizontally symmetrical brackets 8a are provided at both ends of the lifting plate 4. The brackets 8a correspond to the connecting sleeves 8d one by one. The rear end of the bracket 8a has a screw portion 8b, and the screw portion 8b passes through the corresponding connecting sleeve 8d and is fixedly connected to the connecting sleeve 8d, which improves the stability of the lifting plate 4, thereby improving the guiding effect, and making the lifting of the lifting plate 4 stable and reliable.
