Description

Core drilling and sampling device

Technical Field

The utility model belongs to the technical field of the core sample technique equipment of boring and specifically relates to a core appearance extractor is related to.

Background

The core drilling sampling is used for concrete slab type members such as pavements, basic rafts, concrete structural slabs and the like, and aims to verify the strength, crack, thickness and cementation condition of the concrete of the members. One method of core drilling and sampling is the vertical concrete core drilling and sampling method. The method of the prior vertical concrete core drilling sampling method is to use a steel chisel, a crowbar or a screwdriver to knock a hammering core sample, and then grab the sample by hands. The disadvantages of the above method are: it is suitable for the conditions of small and short core sample and light weight, and has limitation. In addition, since this method forcibly impacts the sample, a drill, a crowbar, or a screwdriver easily damages the surface of the sample. In addition, it is not safe to grasp the sample with hands.

Those skilled in the art have therefore sought to develop a core sampler that allows for the rapid and easy removal of a core sample, while reducing the probability of damaging the core sample during coring.

Disclosure of Invention

In view of the above-mentioned defects of the prior art, the technical problem to be solved in the utility model is to provide a core appearance extractor that can swiftly conveniently take out core appearance reduces the core in-process simultaneously and destroys core appearance probability.

In order to achieve the purpose, the utility model provides a bore core sampling device, the electric iron comprises a handle, the handle is connected with a flexible lasso, the front end of handle still is provided with an axial arc chisel.

The LED lamp is further arranged at the front end of the handle, a battery electrically connected with the LED lamp is installed in the handle, and a switch electrically connected with the LED lamp and the battery is installed on the surface of the handle

The lasso is connected with the handle through a steel wire rope.

The side wall of the handle is provided with a tying groove, one end of the steel wire rope is wound on the tying groove, and the other end of the steel wire rope is connected with the lasso.

An elastic rubber strip is wound on the lasso.

The utility model has the advantages that: the utility model discloses a bore core sampling device, including the handle, the handle is connected with a flexible lasso, and the front end of handle still is provided with an axial arc chisel, and the arc chisel is used for chisel disconnected core appearance, and the fracture position of core appearance is entangled to flexible lasso, then mentions the handle alright take out required core appearance, can not touch the core appearance surface of hindering, simple structure, sample convenient and fast.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and examples, wherein it is noted that, in the description of the invention, the terms "upper", "lower", "left", "right", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular manner, and therefore should not be construed as limiting the present invention. The terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1 to 3, a core drilling sampling device comprises a handle 1, the handle 1 is connected with a flexible lasso 2, the front end of the handle 1 is further provided with an axial arc chisel 3, the front end of the handle 1 is further provided with an LED lamp 4, a battery 5 electrically connected with the LED lamp 4 is installed in the handle 1, the surface of the handle 1 is provided with a switch 6 electrically connected with the LED lamp 4 and the battery 5, the lasso 2 is connected with the handle 1 through a steel wire rope 7, a binding groove 8 is formed in the side wall of the handle 1, one end of the steel wire rope 7 is wound on the binding groove 8, the other end of the steel wire rope is connected with the lasso 2, and an elastic rubber strip is wound on the lasso 2.

The utility model discloses a theory of operation is: after the core drilling work is finished, the core sample 9 is erected in the sampling pit 10, the switch 5 is turned on to light the LED lamp 4 to illuminate a gap between the core sample 9 and the sampling pit 10, the position to be cut off of the core sample 9 is determined, referring to fig. 2, the arc-shaped chisel 3 is extended into the gap between the core sample 9 and the sampling pit 10, the sharp part of the arc-shaped chisel 3 is aligned with the position to be cut off, the back part of the arc-shaped chisel 3 is slightly leaned on the pit opening of the sampling pit 10, the handle 1 is pushed by utilizing the lever principle, the arc-shaped chisel 3 cuts off the core sample 9, referring to fig. 3, the core sample 9 is leaned on the side wall of the sampling pit 10 after cutting off, the noose 2 is hung at the cut-off part of the core sample 9, the noose 2 supports the core sample 9 from the bottom due to the friction force between the noose 2 and the core sample 9, particularly, the friction force is further increased by the wound elastic rubber strip, so that the handle is lifted by one hand, the top part of the core sample 9, and the surface of the core sample 9 can not be damaged, the structure is simple, and the sampling is convenient and quick.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
