Description

Technical Field

[0001] This utility model relates to the field of rock core sampling technology, and in particular to an auxiliary fixing device for rock core sampling of irregular rocks. Background Technology

[0002] Irregular rock sampling is an important task in geology, planetary science, and engineering, involving the collection of rocks with unique shapes, fragile structures, or complex textures. The sampling process involves first obtaining irregularly shaped blocks of rock using tools such as geological hammers, chisels, and rock saws. These blocks are then placed on the ground or a tabletop, and a handheld drill is used to extract the sample. Personnel are needed to assist in securing the irregular rock during this process. The above sampling process presents the following problems: 1. Irregular rocks have poor stability and are prone to deviation during sampling, posing a significant safety hazard; 2. Frequent deviation of irregular rocks during sampling leads to poor sample integrity, a large amount of waste rock cores, and increased workload for workers. Utility Model Content

[0004] This utility model is implemented by the following technical solution: an auxiliary fixing device for core sampling of irregular rocks, which includes a base, a fixing seat, a clamping component, and a drilling rig fixing platform. The fixing seat is fixed on the top of one side of the base, and the drilling rig fixing platform is fixed on the top of the base at one end of the fixing seat by a bracket. A clamping component is respectively provided on both sides of the drilling rig fixing platform, and the clamping member of the clamping component is horizontally arranged on the top of the fixing seat.

[0005] Furthermore, the clamping assembly includes two columns, a clamping member slidably disposed between the two columns, and nuts screwed onto the tops of the two columns respectively; each end of the clamping member is fixed with a sleeve movably sleeved outside the corresponding column, and the bottom end of the nut movably abuts against the top of the sleeve; one clamping member is fixed to the top of the base on one side of the drilling rig fixing platform, and the other clamping member is fixed to the top of the base at the other end of the fixing seat.

[0006] Furthermore, a strip-shaped hole is provided on the drilling rig fixing platform, which is arranged perpendicularly to the fixing seat.

[0007] Furthermore, the fixing base includes a first frame and a second frame that are arranged separately at the top and bottom, with multiple pairs of connecting rods connecting the first frame and the second frame; and the size of the first frame is larger than the size of the second frame.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 3 As shown, an auxiliary fixing device for core sampling of irregular rocks includes a base 1, a fixing seat 2, a clamping assembly 3, and a drilling rig fixing platform 4. The fixing seat 2 for placing rocks is fixed on the top of one side of the base 1. The drilling rig fixing platform 4 for installing a sampling drilling rig is fixed on the top of the base 1 at one end of the fixing seat 2 by a bracket 5. A strip hole 41 is opened on the drilling rig fixing platform 4, which is arranged vertically relative to the fixing seat 2. By aligning the mounting hole on the sampling drilling rig base with the strip hole 41, and then passing bolts through the strip hole 41 and the mounting hole on the sampling drilling rig base, the sampling drilling rig can be installed and fixed. The relative position of the mounting hole on the strip hole 41 can be adjusted according to actual needs to adjust the relative position of the sampling drilling rig and the rock on the fixing seat 2.

[0016] A clamping assembly 3 is provided on each side of the drilling rig fixing platform 4. The clamping element 31 of the clamping assembly 3 is horizontally arranged on the top of the fixing seat 2. The clamping element 31 can clamp the rock to the top of the fixing seat 2. The clamping element 31 is a steel cable or a pressure rod. In this embodiment, the clamping element 31 is a pressure rod; in some embodiments, the clamping element 31 can be a steel cable. The steel cable has a higher degree of contact with the rock and a better fixing effect.

[0017] In this embodiment, the fixing base 2 includes a first frame 21 and a second frame 22, which are arranged in two separate parts. Multiple pairs of connecting rods 23 are connected between the first frame 21 and the second frame 22. The size of the first frame 21 is larger than that of the second frame 22. In this embodiment, the first frame 21, the second frame 22, and the connecting rods 23 together constitute a frame-type, funnel-shaped fixing base 2 structure, which has a strong capacity and can be used to hold various irregular rocks. The edges of the irregular rocks can be placed in the hollow parts of the frame structure to solve the problem of rock disintegration during sampling. In addition, each pair of connecting rods 23 can guide and position the rocks, which helps to achieve stable fixing of irregular rocks.

[0018] The clamping assembly 3 includes two columns 32, a clamping member 31 slidably disposed between the two columns 32, and nuts 33 screwed onto the tops of the two columns 32 respectively. Sleeves 34, movably sleeved outside the corresponding columns 32, are fixed to both ends of the clamping member 31, with the bottom end of the nut 33 movably abutting against the top of the sleeve 34. One clamping member 31 is fixed to the top of the base 1 on one side of the drilling rig fixing platform 4, and the other clamping member 31 is fixed to the top of the base 1 at the other end of the fixing seat 2. The position of the clamping member 31 on the columns 32 can be adjusted according to the height of the rock. Then, by rotating the nut 33 downwards, the clamping member 31 can be pressed against the top of the rock, achieving the clamping and fixing of the rock.

[0019] Instructions for use:

[0020] First, rotate nut 33 to move it to the top of the corresponding column 32;

[0021] Then, move the clamping member 31 upward to the upper part of the column 32;

[0022] Next, place the rock inside the fixing seat 2, then loosen the clamping member 31. The clamping member 31 falls down along the column 32 to the top of the rock. Then, rotate the nut 33 in the opposite direction to move it downwards until it abuts against the top of the corresponding sleeve 34, thereby pressing and fixing the rock inside the fixing seat 2.

[0023] Finally, place the base of the sampling drill 6 on top of the drilling fixed platform 4, align the mounting hole on the sampling drill base with the strip hole 41, and adjust the drill bit of the sampling drill 6 to be above the rock between the two clamping members 31. Then, bolts are used to connect and fix the mounting base and the drilling fixed platform 4, and sampling can begin.
