Description

Technical Field

[0001] This utility model specifically relates to a positioning and marking device for rock and soil exploration. Background Technology

[0002] Geotechnical exploration refers to the process of investigating and analyzing rocks and soils in a geological environment using various methods and techniques to obtain information such as underground geological structure, soil properties, and rock composition. Geotechnical exploration has wide applications in civil engineering, geology, mining, and environmental science. Positioning and marking devices play a crucial role in geotechnical exploration, ensuring the accurate location and recording of exploration points. Their main functions include:

[0003] (1) Mark the location of exploration points, that is, mark the specific location of exploration points on the ground with physical markers (such as marker poles, flags, etc.) to facilitate subsequent observation and data collection.

[0004] (2) Ensure the visibility of the exploration point by using bright colors or reflective materials so that the marking device can be clearly seen in various environments, avoiding errors and confusion.

[0005] Currently, the positioning markers for exploration holes on the market are mostly marked by inserting bamboo strips, tree branches, spraying paint, or binding plastic bags. The bamboo strips and tree branches are used to attach the plastic bags, and the exploration hole information is placed in the plastic bags. However, the bamboo strips and tree branches used are easy to be pulled off by people, and the exploration hole information in the plastic bags is very easy to be damaged in bad weather such as rain and wind. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning and marking device for rock and soil exploration.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A positioning and marking device for geotechnical exploration includes a positioning bracket, a fixing mechanism installed inside the positioning bracket, and a marking head fixedly installed above the fixing mechanism. The fixing mechanism includes a screw threadedly fitted to the positioning bracket, a wrench fixedly installed at the upper end of the screw, a disc fitted at the lower end of the screw, an anti-loosening sleeve fixed at the lower end of the screw to prevent the disc from loosening, and a plurality of tensioning mechanisms hinged around the edge of the disc and movable in conjunction with the positioning bracket.

[0009] Preferably, the upper end of the screw is integrally formed with a threaded head, and the marking head is fixed by screwing into the threaded head;

[0010] Furthermore, the lower end of the screw is integrally formed with an assembly head having a screw hole.

[0011] Preferably, a disc hinge seat is integrally formed below the edge of the disc, with the number of such seats matching the number of the tensioning mechanisms.

[0012] Preferably, the tensioning mechanism includes a movable arm, a strip-shaped limiting groove formed on the movable arm, a limiting shaft passing through the strip-shaped limiting groove, and a support plate mounted to the lower end of the movable arm via a hinge.

[0013] Furthermore, a hinged support seat is welded to the inner center of the support plate;

[0014] Furthermore, the outer side of the support plate is integrally formed with tapered points.

[0015] Preferably, the positioning bracket includes a bracket body with a screw hole at the upper end, bracket hinge seats welded to the middle of the inner side of the bracket body and evenly distributed, a bottom cover that is tightly attached to the bottom of the bracket body and fixed by screws, and a pin welded to the bottom of the bottom cover.

[0016] Preferably, the outer side of the sign head is covered with several reflective strips;

[0017] Furthermore, a numbered circular patch is embedded at the top of the label head.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The screw drives the disc downward, causing multiple hinged tensioning mechanisms to expand outward synchronously, making the support plate tightly fit against the inner wall of the borehole, forming multi-point uniform support. This effectively prevents the device from loosening or shifting inside the borehole, adapting to different hole diameters and soil conditions. The anti-disengagement sleeve is fixed to the assembly head at the end of the screw with bolts, ensuring that the disc will not fall off when the screw rotates. In addition, the tapered point on the outer side of the support plate is embedded in the borehole wall to enhance friction and prevent slippage. Furthermore, the limiting shaft cooperates with the strip-shaped limiting groove to constrain the movement trajectory of the movable arm and improve stability.

[0020] 2. Simply rotating the wrench allows for simultaneous screw advancement, disc depressing, and support plate expansion, eliminating the need for additional tools or complex procedures and significantly reducing fieldwork time. Furthermore, the tensioning mechanism allows for flexible adjustment of the expansion angle, making it suitable for drilling holes of different diameters. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0025] Example

[0026] A positioning and marking device for geotechnical exploration includes a positioning bracket 1, a fixing mechanism 2 installed inside the positioning bracket 1, and a marking head 3 fixedly installed above the fixing mechanism 2.

[0027] The positioning bracket 1 includes a bracket body 11 with a screw hole at the upper end, bracket hinge seats 12 welded to the inner middle of the bracket body 11 and evenly distributed, a bottom cover 13 tightly attached to the bottom of the bracket body 11 and fixed with screws, and a pin 14 welded below the bottom cover 13. Specifically, the bracket hinge seat 12 is used to fix the limiting shaft 253. When the screw 21 is rotated, the disc 23 is pressed down, causing the movable arm 251 to move around the limiting shaft 253 and open the support plate 254, so that the support plate 254 is tightly attached to and fixed to the inner wall of the drilled hole, thus completing the fixed installation of the entire device.

[0028] The fixing mechanism 2 includes a screw 21 threadedly fitted to the positioning bracket 1, a wrench part 22 fixedly installed on the upper end of the screw 21, a disc 23 fitted on the lower end of the screw 21, an anti-loosening sleeve 24 fixed on the lower end of the screw 21 to prevent the disc 23 from loosening, and several tensioning mechanisms 25 hinged around the edge of the disc 23 and movable in conjunction with the positioning bracket 1.

[0029] The upper end of the screw 21 is integrally formed with a threaded head 211, and the marking head 3 is fixed by screwing into the threaded head 211;

[0030] The lower end of the screw 21 is integrally formed with an assembly head 212 with a screw hole. Specifically, it can be fitted with an anti-loosening sleeve 24 and screwed in a bolt for fixation. When the screw 21 rotates, it will not be obstructed by the disc 23, and at the same time, it prevents the disc 23 from loosening.

[0031] The disc 23 has an integrally formed disc hinge seat 231 below the edge, which is the same number as the tensioning mechanism 25. Specifically, the disc hinge seat 231 is used to hinge the tensioning mechanism 25.

[0032] The tensioning mechanism 25 includes a movable arm 251, a strip-shaped limiting groove 252 formed on the movable arm 251, a limiting shaft 253 passing through the strip-shaped limiting groove 252, and a support plate 254 mounted to the lower end of the movable arm 251 via a hinge shaft.

[0033] A hinge seat 2541 is welded to the middle of the inner side of the support plate 254. Specifically, it can be installed with the movable arm 251 through a hinge shaft. The movable arm 251 can flexibly open the support plate 254 so that the support plate 254 is opened and tightly fixed to the inner wall of the drilled hole.

[0034] The outer side of the support plate 254 is integrally formed with a tapered point 2542. Specifically, the support plate 254 is opened and tightly fixed to the inner wall of the drilled hole, and the tapered point 2542 can prevent slipping.

[0035] It should be further explained that by driving the disc downward through the screw, multiple hinged tensioning mechanisms expand outward simultaneously, making the support plate tightly fit against the inner wall of the borehole, forming multi-point uniform support, effectively preventing the device from loosening or shifting inside the borehole, adapting to different hole diameters and soil conditions. The anti-disengagement sleeve is fixed to the assembly head at the end of the screw with bolts to ensure that the disc will not fall off when the screw rotates. Moreover, the conical point on the outer side of the support plate is embedded in the borehole wall to enhance friction and prevent slippage. In addition, the limiting shaft cooperates with the strip-shaped limiting groove to constrain the movement trajectory of the movable arm and improve stability.

[0036] Therefore, when using this device, simply rotating the wrench will simultaneously complete the screw advance, disc depressing and support plate expansion actions, without the need for additional tools or complicated steps, significantly reducing field operation time. Moreover, the tensioning mechanism can flexibly adjust the expansion angle, making it suitable for drilling holes of different diameters.

[0037] The outer side of the marker head 3 is covered with several reflective strips 31 to indicate the location of the marking device; the top of the marker head 3 is fitted with a numbered circular patch 32 to mark the specific sequence number of the geotechnical exploration at that location. Specifically, the reflective strips provide high visibility at night or in low light conditions, facilitating rapid positioning; while the numbered circular patch records the exploration point sequence number, avoiding errors from manual recording and supporting digital management.

[0038] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
