Description
Technical field
Compression leg leading screw lift device device of the present invention, belong under the coal mine winch, flight conveyer etc. fixedly supporting use the mechanical lifting gear technical field.
Background technique
The winch that mining face under mine and tunnel are used generally adopts concrete foundation to fix, and roving winch or jury winch generally adopt fixedly supporting of round log, because the length of round log is certain; Winch is under the situation that does not receive tractive force; Round log setting pressure between top board and the winch is very little, adds the not sclerosis of some back, and coal body is softer; Winch possibly be inserted in the top board coal body at round log under the effect of heavy load tractive force and go; Winch produces displacement makes round log lose fixedly support action, the whole supporting of winch was lost efficacy, even cause the generation of shipping accident; Flight conveyer belongs to roving machinery; So generally adopting round log to make compression leg fixes head, tail; Same length owing to round log is fixed; Do not have enough big setting pressure, add flight conveyer the time be in vibrational state always in work, thus adopt separately round log fixedly supporting effect be not fine.
Summary of the invention
The present invention overcomes the deficiency that existing technology exists, and technical problem to be solved provides small and exquisite, easy to use safe, the fixed compression leg leading screw lift device device of a kind of structure.
For solving the problems of the technologies described above; The technological scheme that the present invention adopted is: compression leg leading screw lift device device; Comprise swivel nut in end boots, first leading screw, the interior swivel nut of second leading screw, leading screw, round log connecting base and round log cap bag; The structure of end boots is: cylinder vertically is fixed on the base plate top, and the interior swivel nut of the swivel nut and second leading screw is the cylinder that inwall one end is provided with internal thread in first leading screw, and the interior swivel nut of first leading screw does not have an end of internal thread to be sleeved on outside the cylinder and the end contacts with base plate; One end of leading screw is screwed into the end that the interior swivel nut of first leading screw is provided with internal thread; The other end of leading screw is screwed into the end that the interior swivel nut of second leading screw is provided with internal thread, and the other end end of swivel nut is equipped with the round log connecting base of tubbiness in second leading screw, and the round log cap bag of being inverted tubbiness vertically is positioned at the top of round log connecting base;
The two ends of said leading screw have the opposite outside thread of rotation direction.
Swivel nut is fastening fixing through circular pin in the cylinder in the boots of the said end and first leading screw.
Parallel welding in the top of described round log cap bag or straight line are welded with the slideproof tooth of two inverted triangle shapes.
The sidewall of said round log connecting base and round log cap bag all has tapped hole, all is connected with a bolt in each tapped hole.
The middle part of said leading screw has radial direction through hole.
Described base plate is inverted groove shape, or below square plate, evenly is provided with a plurality of supporting foots, or below circular plate, is provided with a plurality of supporting foots.
The present invention compares with existing technology has following beneficial effect.
1, to have adopted two ends be the leading screw and the round log connecting base that is connected with round log, round log cap bag of reverse thread in the present invention, only needs to insert in the hole in the middle of the leading screw with iron rod to rotate the up-down that just can accomplish round log, and structure is small and exquisite, and is easy to use, also provides cost savings.
2, end boots among the present invention or be inverted groove shape or be provided with a plurality of supporting foots are welded with slideproof tooth on the round log cap bag, only need on the base of flight conveyer that contact with end boots or winch, add rubber, just can prevent that contact from skidding, and are firm more safely.
3, the present invention makes round log be connected with the round log cap bag with the round log connecting base with bolt, prevents that being connected not firm dropping with round log hurts sb.'s feelings, and safety is firm more.
4, the end of the present invention boots are connected fixing with leading screw with circular pin with suit; Just can change different end boots according to the flight conveyer of different model or the different bases of winch; Change the different diameters and the leading screw of material according to different purposes, replacing is convenient also to be provided cost savings.
