Description

Technical Field

[0002] In geotechnical engineering surveys, it is often necessary to lift and transport geotechnical cores, so a lifting device is needed for geotechnical engineering survey coring.

[0003] For example, the patent publication number CN220265136U is a lifting device for geotechnical engineering survey and coring. It controls the operation of the driving component to make the screw start to rotate, so that the sliding frame drives the limit plate to slide toward the side close to each other, and fixes the geotechnical core in the lifting frame to prevent the geotechnical core from shaking and displacing during the lifting process, thereby causing damage to the geotechnical core.

[0004] However, in actual use of the above-mentioned lifting device for geotechnical engineering survey and coring, each time the geotechnical core is placed, it is necessary to wait for the control mechanism to fix and limit the two sides of the geotechnical core, and manually pry open the protective plate to fix and limit the top of the geotechnical core.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In engineering surveys, it is often necessary to perform coring operations on rock and soil. After coring, in order to facilitate the collection of the cores by the workers on the ground, the rock and soil cores need to be lifted and transported. Therefore, a lifting device for geotechnical engineering survey coring is needed. In actual use, most of the traditional geotechnical engineering survey coring lifting devices are cumbersome to operate during the loading and collection of the device, which reduces the speed of rock and soil core transportation and the convenience of the device. For this reason, the applicant proposes a lifting device for geotechnical engineering survey coring.

[0024] like Figure 1-Figure 6As shown, the utility model provides a technical solution: a lifting device for coring in geotechnical engineering survey, comprising a geotechnical coring lifting base 1, a placing mechanism 2 is in contact with the top center of the geotechnical coring lifting base 1, the placing mechanism 2 comprises a plurality of placing boxes 201, the box opening of the placing box 201 is located at the top, and fixing blocks 202 are respectively fixed on both sides of the bottom of the inner wall of the placing box 201, and the tops of the opposite surfaces of the two fixing blocks 202 are respectively provided with inclined surfaces, and the inclined surfaces of the two fixing blocks 202 are respectively fixed with a plurality of soft rubber pads 203, and a soft board 204 is fixed at the center of the bottom of the inner wall of the placing box 201, and the top center of the soft board 204 is located at the top center of the soft board 204. A relay rod 205 is fixed to the placement box 201, and two rotating plates 206 are connected to rotate together on both sides of the inner wall of the placement box 201. Buckle rods 207 are fixed to the tops of the opposite surfaces of the two rotating plates 206, and fixed rods 208 are fixed to the bottoms of the opposite back surfaces of the two rotating plates 206. Inclined rods 209 are fixed to the other two sides of the inner wall of the placement box 201, and the inclined surfaces of the two inclined rods 209 are symmetrical to each other. Lifting mechanisms 3 are fixed to both sides of the top of the geotechnical coring lifting base 1, and the inner walls of the lifting mechanisms 3 are connected to the outer walls of the placement mechanism 2. A plurality of springs 210 are fixed to the inclined surfaces of the inclined rods 209. One end of the spring 210 is fixed to one side of an adjacent fixed rod 208. A slide plate 211 is fixed to the center of both sides of the inner wall of the placement box 201. The slide groove walls of the two slide groove plates 211 are slidably connected with a lifting frame 212. A movable plate 213 is fixed to the bottom end of the lifting frame 212. The bottom of the movable plate 213 contacts the bottom of the inner wall of the placement box 201. Connecting blocks 214 are fixed to both sides of the box opening of the placement box 201. The soft board 204 is located between the bottoms of the opposite surfaces of the two fixed blocks 202. The sum of the widths of the adjacent soft rubber pads 203 in the horizontal direction must be less than or equal to the distance between the opposite surfaces of the two fixed blocks 202. The sum of the heights of the plate 204 and the relay rod 205 must be smaller than the height of the fixed block 202. The two rotating plates 206 are respectively located on the top of the two fixed blocks 202, and the bottoms of the two rotating plates 206 are located between the opposite surfaces of the two fixed blocks 202. The lengths of the soft rubber pad 203, the soft plate 204 and the relay rod 205 are all equal. The sum of the length of the soft rubber pad 203 and the length of the two movable plates 213 must be equal to the length of the bottom of the inner wall of the placement box 201. The shortest distance between the two rotating plates 206 must be greater than or equal to the width of the slide plate 211. The height of the lifting frame 212 must be greater than the height of the inner wall of the placement box 201.

[0025] It should be noted that: first, the device is placed in the corresponding position. After completing the geotechnical engineering survey and coring, the geotechnical core is placed in the placement box 201. As the geotechnical core is placed in the placement box 201, the rotating plate 206 will rotate due to the weight of the geotechnical core. At this time, the buckle rod 207 will limit and fix the top two sides of the geotechnical core. At the same time, the two groups of soft rubber pads 203 will also deform due to the weight of the geotechnical core, and one side of the two groups of soft rubber pads 203 will contact the bottom two sides of the geotechnical core. In addition, the inclined surfaces of the opposite surfaces of the two fixing blocks 202 are used to adjust the rock. The two sides of the bottom of the soil core are limited and fixed. At the same time, when the geosoil core is completely inside the placement box 201, the bottom of the geosoil core will also contact the relay rod 205. At this time, the relay rod 205 will bear the weight of the geosoil core and make the center of the placement box 201 at the center position of the bottom of the inner wall. During transportation, the stability of the placement box 201 can be ensured. When taking out the geosoil core, only the two lifting frames 212 need to be lifted to take out the geosoil core, and then the two rotating plates 206 will be reset under the action of two sets of springs 210.

Stabilizing blocks 308 are fixed to the bottom ends of the two outer boxes 301, and support plates 309 are fixed on both sides of the top of the stabilizing blocks 308. Stabilizing blocks 310 are fixed between the opposite surfaces of adjacent support plates 309 and the outer walls of the adjacent outer boxes 301.

At this time, the two sets of secondary sprockets 304 will also rotate, so as to improve the stability of the chains 305 during operation. Due to the movement of the two chains 305, the two moving belts 306 will also be driven to move. At this time, the two sets of connecting rods 307 on the two moving belts 306 will drive the placement mechanism 2 to perform lifting and lowering movements.
