Description

Technical Field

[0001] The utility model belongs to the technical field of geological engineering exploration, and in particular relates to a coring fixing device for geological engineering exploration. Background Art

[0002] Geological engineering survey is a geological investigation and research work carried out to identify the geological factors that affect engineering buildings. After identifying the engineering geological conditions, it is necessary to predict the mode, characteristics and scale of the interaction between the engineering building and the geological environment (i.e., engineering geological action) based on the structure and operation characteristics of the designed building, and make a correct evaluation to provide a basis for determining protective measures to ensure the stability and normal use of the building.

[0003] In the process of realizing the utility model, the inventors found that there are at least the following problems in this technology: in geological engineering exploration work, it is often necessary to use coring facilities to take cores (substances that can represent the components of the formation) inside the formation, but such coring facilities are usually integrated with the device that fixes them, resulting in the core tubes thereon being unable to be replaced, and thus being unable to adapt to different types of coring work.

[0004] Therefore, we propose a coring fixture for geological engineering exploration to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a coring fixing device for geological engineering exploration, which can replace coring tubes of different specifications, so that the device has a wider application range and can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A coring fixing device for geological engineering exploration comprises a base and a coring fixing mechanism located on the base, four columns are welded on the base, and a cross frame is welded on the four columns, wherein a hydraulic cylinder is installed at the center of the top wall of the cross frame, wherein a transmission rod is connected below the hydraulic cylinder, and a lifting platform is welded at the bottom of the transmission rod, wherein a bottom frame is integrally welded to the bottom wall of the lifting platform, and a motor is vertically installed in the bottom frame, and the coring fixing mechanism comprises a mounting plate coaxially connected to the output shaft of the motor;

[0008] A receiving groove is formed on the bottom wall of the mounting plate, and a positioning ring is inserted in the receiving groove, wherein the bottom wall of the positioning ring is coaxially connected to a core tube, and four side grooves are formed in the receiving groove toward the mounting plate, and the four side grooves are distributed in a circular array along the central axis of the mounting plate, and an insert block and two springs connected to the insert block are slidably provided in each side groove, and a side of the spring facing away from the insert block is connected to the inner wall of the side groove, and a groove is provided on the four sides of the outer wall of the positioning ring, and the insert blocks in the four side grooves are respectively inserted into the four grooves, so that the positioning ring is confined in the receiving groove and cannot be separated, and a positioning rod that slides through the mounting plate and extends to the outside of the mounting plate is also connected to the insert block, and the positioning rod is used for human hand holding.

[0009] As a preferred embodiment, the transmission rod is vertically arranged and fixedly connected to the bottom wall of the cross frame, so that the transmission rod and the structure below it remain stable and can be normally extended and retracted.

[0010] As a preferred implementation scheme, sliding rods are symmetrically connected on both sides of the top wall of the lifting platform, and both sliding rods slide through the cross frame; so that when the lifting platform is lifted or lowered, the two sliding rods can be driven to slide on the cross frame, thereby ensuring the stability of the lifting platform when it is lifted or lowered.

[0011] As a preferred embodiment, the positioning ring fits with the top wall and the inner wall of the receiving groove, so that the positioning ring will not shake in the receiving groove, thereby keeping the core tube structure stable.

[0012] As a preferred embodiment, a plug hole penetrating the top wall and the bottom wall of the base is provided, and a core sampling tube passes through the plug hole and extends to the bottom of the base, so as to perform coring of the stratum below the base.

[0013] In summary, the technical effects and advantages of the utility model are as follows:

[0014] The coring fixing device for geological engineering exploration drives the lifting platform to sink through the operation of the hydraulic cylinder, so that the coring tube can be drilled into the formation to perform coring work. If it is necessary to replace the coring tube of different caliber, it is only necessary to pull the four positioning rods at the same time to separate the positioning ring on the coring tube from the mounting plate, and then the coring tube of different specifications can be replaced, making the device more applicable.

[0022] A receiving groove 13 is formed on the bottom wall of the mounting plate 9, and a positioning ring 10 is inserted into the receiving groove 13, wherein the bottom wall of the positioning ring 10 is coaxially connected with a core tube 11, and the positioning ring 10 fits with the top wall and the inner wall of the receiving groove 13, so that the positioning ring 10 will not shake in the receiving groove 13, thereby keeping the structure of the core tube 11 stable, and a plug hole 12 penetrating through the top wall and the bottom wall of the base 1 is opened, and the core tube 11 passes through the plug hole 12 and extends to the bottom of the base 1, so as to coring the formation below the base 1;

[0023] Four side grooves 14 are formed in the receiving groove 13 toward the mounting plate 9, and the four side grooves 14 are distributed in a circular array along the central axis of the mounting plate 9. An insert block 17 and two springs 15 connected to the insert block 17 are slidably provided in each side groove 14. The side of the spring 15 facing away from the insert block 17 is connected to the inner wall of the side groove 14.
