Abstract
The utility model provides a support instrument, constitute by base (5), its difference lies in the upper end fixed connection lower prop (4) of base (5), the upper end swing joint of lower prop (4) is in the inside of last prop (2), the upper end binding steel board (1) of going up prop (2), the lower extreme fixed connection adjusting nut (3) of going up prop (2), adjusting nut (3) and lower prop (4) swing joint, therefore it is high to strut intensity, durable, and this device struts and demolishs the work easy operation, repeatedly usable, it is laborsaving economize material, guarantee borehole operation safety, be particularly suitable for the mine underground temporary support and use.
Description
Technical field:
The utility model relates to a kind of supporting instrument, particularly relates to the supporting instrument that the down-hole temporary lining of a kind of mine is used.
Background technology:
In bargh; Country rock built on the sand in the mine is a big hidden danger of safety in production always; Tended to cause very big threat if the country rock built on the sand in the operation process can not in time take precautions against,, adopt at present usually round log that country rock is built on the sand carried out temporary lining so just need carry out temporary lining to these places to safety in production; But the size of round log and length are fixed often, often because of the off size supporting effect that can not reach best of fitting.
Summary of the invention:
The purpose of the utility model will provide a kind of exactly can effectively improve supporting intensity, convenient and practical, reusable supporting instrument.
The purpose of the utility model is achieved in that a kind of supporting instrument; Form by base; The upper end that it is characterized in that described base is fixedly connected lower supporting rod, and the upper end of lower supporting rod is movably connected in the inside of upper supporting column, and the upper end of upper supporting column connects steel plate; The lower end of upper supporting column is fixedly connected adjusting nut, and adjusting nut and lower supporting rod flexibly connect.
An optimum implementation of the utility model is: there is screw thread the upper end of lower supporting rod.
The utility model compared with prior art has the following advantages:
Because adopted the upper end of base to be fixedly connected lower supporting rod, the upper end of lower supporting rod is movably connected in the inside of upper supporting column, the upper end of upper supporting column connects steel plate; The lower end of upper supporting column is fixedly connected adjusting nut, the form of structure that adjusting nut and lower supporting rod flexibly connect, thereby supporting intensity is high; Durable, and this device supporting is easy, reusable with the dismounting operation; Labor and material saving ensures underground work safety.

The specific embodiment:
The upper end of base 5 is fixedly connected lower supporting rod 4; The upper end of lower supporting rod 4 is movably connected in the inside of upper supporting column 2, and the upper end of upper supporting column 2 connects steel plate 1, and the lower end of upper supporting column 2 is fixedly connected adjusting nut 3; Adjusting nut 3 flexibly connects with lower supporting rod 4, and there is screw thread the upper end of lower supporting rod 4.
During use, regulate the height of supporting instrument through rotation adjusting nut 3, to reach best supporting effect; During dismounting if in the opposite direction rotation adjusting nut 3 to reduce the whole height of these devices dismountable, easy to use, durable; Time saving and energy saving, safe and efficient.
Claims (2)
1. supporting instrument; Form by base (5); The upper end that it is characterized in that described base (5) is fixedly connected lower supporting rod (4), and the upper end of lower supporting rod (4) is movably connected in the inside of upper supporting column (2), and the upper end of upper supporting column (2) connects steel plate (1); The lower end of upper supporting column (2) is fixedly connected adjusting nut (3), and adjusting nut (3) flexibly connects with lower supporting rod (4).
2. a kind of supporting instrument according to claim 1 is characterized in that there is screw thread the upper end of described lower supporting rod (4).
