Abstract
The utility model discloses a supporting tool, which consists of a base (5). The supporting tool is characterized in that: the upper end of the base (5) is fixedly connected with a lower supporting column (4), the upper end of the lower supporting column (4) is movably connected to the inner part of an upper supporting column (2), the upper end of the upper supporting column (2) is connected with a steel plate (1), the lower end of the upper supporting column (2) is fixedly connected with an adjusting nut (3), and the adjusting nut (3) is movably connected with the lower supporting column (4). Therefore, the supporting tool has high supporting strength, and is firm and durable. Moreover, the supporting tool is easy to operate in supporting and detaching work, can be reused, saves labor and materials, ensures the safety of underground operation, and is particularly suitable for underground temporary supporting for a mine.
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.

1, steel plate 2, upper supporting column 3, adjusting nut 4, lower supporting rod 5, base
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.
