Description

Lifting device for filter in-situ leaching uranium mining process

Technical Field

The utility model relates to a technical field of ground soaks uranium mining device, in particular to hoisting device for filter among ground soaks uranium mining technology.

Background

The reaming type drilling structure is widely applied to the in-situ leaching uranium mining process, namely, after open hole construction is completed, a sleeve is placed down for installation, reverse grouting is performed in a hole, well cementation is completed, an ore layer section is an open hole section, after well washing is completed, a filter is arranged below the well, and finally drilling construction is completed.

Foretell filter adopts and pastes the gravel filter, and the top of filter is the bayonet socket of "L" type, and traditional hoisting device is the solid tube of the slightly little filter bayonet socket of internal diameter, and each 3cm long high strength steel bars of welding are gone left and right sides of solid tube. But the following problems exist in the using process: 1. the lifting device is not easy to be matched with the L-shaped bayonet, the lifting device needs to rotate rightwards when being placed into the L-shaped bayonet, and the rotating angle of the lifting device is smaller when the lifting device is rotated on the ground surface in a hole with the drilling depth of more than 400 meters; 2. the high-strength steel bar is easy to fall off, and when the stress is large, the welding area of the welding point of the high-strength steel bar is small, and the welding is easy to open; 3. the L bayonet is easy to be damaged, and when the stress is large, the L bayonet is easy to be opened by the lifting device, so that the consequence of lifting failure is caused.

SUMMERY OF THE UTILITY MODEL

The utility model provides a hoisting device for filter among ground leaching uranium mining technology has solved current hoisting device and has used inconveniently and can't keep promoting or transfer the problem of process stability.

In order to achieve the above purpose, the technical scheme of the utility model is as follows: a lifting device for a filter in an in-situ leaching uranium mining process comprises a protective sleeve section and a gear clamping mechanism, wherein the protective sleeve section comprises a spherical cone and a knife sheath arranged on the spherical cone; the gear clamping mechanism comprises two gear cutters, the two gear cutters are symmetrically arranged on a spherical cone, each gear cutter is rotatably connected with the spherical cone, and each gear cutter is positioned on the rotating track of the gear cutter on the corresponding side.

Further, the diameter of the spherical cone is 40-50mm.

Further, the width of the sheath is 10-12mm.

Furthermore, every wear to be equipped with the steel pin of setting on the spherical centrum on the pinion cutter, the diameter of steel pin is 5mm, the interval of steel pin and pinion cutter inboard is 8mm, the interval of steel pin and pinion cutter outside is 15mm.

Compared with the prior art, the beneficial effect of this scheme:

the scheme realizes effective lifting of the reaming type drilling structure filter, and realizes quality improvement, efficiency improvement and consumption reduction so as to solve the problems of damage of a traditional lifting device, damage of an 'L' -shaped bayonet and low efficiency.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments:

reference numerals in the drawings of the specification include: the device comprises a spherical cone 1, a knife sheath 2, a gear knife 3 and a steel pin 4.

Examples

As shown in figures 1 to 3: a lifting device for a filter in an in-situ leaching uranium mining process comprises a protective sleeve section and a gear clamping mechanism, wherein the protective sleeve section comprises a spherical cone 1 and a sheath 2 arranged on the spherical cone, the diameter of the spherical cone 1 is 40-50mm, and the width of the sheath 2 is 10-12mm. The gear blocking mechanism comprises two gear cutters 3, the two gear cutters 3 are symmetrically arranged on a spherical cone, each gear cutter 3 is rotatably connected with the spherical cone, and each cutter is positioned on the rotating track of the gear cutter 3 on the corresponding side. Each gear knife 3 is provided with a high-strength steel pin 4 fixedly arranged on the spherical cone body in a penetrating way, and the gear knife 3 is rotationally connected with the steel pin 4. The diameter of the steel pin 4 is 5mm, the distance between the steel pin 4 and the inner side of the gear cutter 3 is 8mm, and the distance between the steel pin 4 and the outer side of the gear cutter 3 is 15mm.

The working process of the technical scheme is as follows: the spherical cone 1 is placed into a bayonet of the filter, the gear cutter 3 is opened through the gravity center offset of the gear cutter 3, the gear cutter 3 rotates compared with the spherical cone 1, one side of the gear cutter 3 is positioned outside the spherical cone 1 through cutting, and the gear cutter 3 is engaged with an inner tube of the filter at the moment. When lifted upwards, the upward force drives the occlusal force to increase, thereby realizing the lifting.

The above are merely examples of the present invention, and the common general knowledge of known specific structures and/or characteristics of the schemes is not described herein in excess. It should be pointed out that, for the person skilled in the art, without departing from the structure of the invention, several variants and modifications can be made, which should also be regarded as the scope of protection of the invention, which will not affect the effectiveness of the implementation of the invention and the utility of the patent. The scope of the claims of the present application shall be defined by the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
