Abstract
The utility model relates to an antiskid support, belonging to the technical field of mining. The antiskid support is of a bottomed hollow cylindrical structure as a whole; the internal bottom of a cylinder is provided with axial grooves; compression springs and wedge-shaped-head cylinders are mounted in the axial grooves; the wedge-shaped-head cylinders extend out of through holes of the internal wall of the cylinder; and axial small wings are mounted on side faces of the wedge-shaped-head cylinders. According to the antiskid support, when a caving mining method is adopted for mining, a tracer material container can be reliably fixed at the bottom of a blast hole under the condition that the inclination angle of the blast hole is relatively big.
Description
Technical field
The utility model relates to a kind of anti-sliding pallet, belongs to the mining technique field.
Background technology
When adopting caved stopes mining; The container of ore deposit rock contact-making surface tracer material (ferromagnetism powder, magnetic liquid, dye etc.) (or material volume) is in bottom, the big gun hole process of packing into; When inclination angle, big gun hole is big; Frictional force between container (or material volume) self and big gun hole wall is not enough to retrain it and skids off the big gun hole, makes troubles to mining processes.The tracer material container (or material volume) that how to prevent to pack in the big gun hole skids off, and is a problem demanding prompt solution.
Summary of the invention
The purpose of the utility model provides a kind of anti-sliding pallet, and ore deposit rock contact-making surface tracer material container is difficult for being fixed in the problem of bottom, big gun hole when adopting caved stopes to solve.
The technical scheme of the utility model is: a kind of anti-sliding pallet, and whole for being with end hollow cylinder structure.Hollow space is anti-sliding pallet hollow section 5, in order to place the tracer material container.The cylinder inner bottom part is provided with axial notch 3, and compression spring 2 and sphenocephaly cylinder 1 are housed in the axial notch 3, and sphenocephaly cylinder 1 stretches out in the through hole of cylinder inner wall, and axial winglet 4 is equipped with in its side, rotates to prevent sphenocephaly cylinder 1.
Anti-skidding rest device material should adopt the steel surplus rigid plastics or the steel of adopting except that the compression spring.Anti-sliding pallet diameter is less than blasthole diameter, and sphenocephaly cylinder 1 length and compression spring 2 length sum when compressive state fully makes anti-sliding pallet can put into the big gun hole smoothly also less than blasthole diameter.The tapered end of sphenocephaly cylinder 1 closely contacts with the big gun hole wall, and when compression spring 2 was not stressed, the hole exterior portions that guarantees sphenocephaly cylinder 1 was no longer than wedge-shaped segment.
During use, tracer material container (or material volume) is placed anti-sliding pallet hollow section 5, and with tracer material container (or material volume) (aim at big gun hole at the bottom of direction) forward.Push the big gun hole to tracer material container (or material volume) and anti-sliding pallet then, and at the bottom of adopting suitable utensil to shift it onto big gun hole.Because the non-return effect of anti-skidding rest device can be fixed in bottom, big gun hole with tracer material container (or material volume) reliably.Carry out dynamite charge at last.
The beneficial effect of the utility model is: when adopting caved stopes mining, under the bigger condition in inclination angle, big gun hole, can reliably the tracer material container be fixed in bottom, big gun hole.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the internal structure sketch map of the utility model.
Each label is among the figure: 1: sphenocephaly cylinder, 2: compression spring, 3: axial notch, 4: axial winglet, 5: anti-sliding pallet hollow section.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further, but the content of the utility model is not limited to said scope.
Embodiment 1: a kind of anti-sliding pallet, and whole for being with end hollow cylinder structure.Hollow space is anti-sliding pallet hollow section 5, in order to place the tracer material container.The cylinder inner bottom part is provided with axial notch 3, and compression spring 2 and sphenocephaly cylinder 1 are housed in the axial notch 3, and sphenocephaly cylinder 1 stretches out in the through hole of cylinder inner wall, and axial winglet 4 is equipped with in its side, rotates to prevent sphenocephaly cylinder 1.
