At present, Jack is relatively large apparatus mostly, and volume is big, and weight is also heavy, the extremely clumsy inconvenience of transportation in the use, and some occasion is not fit to this relatively large Jack, exists and uses drawback.For example in current earthquake relief work process,, caused very big difficulty to disaster relief operations because the variation that topographic structure takes place causes large-scale Jack just not enter the scene at all.
Three, summary of the invention
The utility model purpose is to solve the deficiency that above-mentioned prior art exists, provide a kind of volume little, in light weight, be convenient to transportation, need not any mechanical power can use, and uses flexible detachable triangular hoisting jack.
A kind of triangular hoisting jack of the present utility model, special character are to comprise A-frame 4, crowbar 1, and A-frame 4 tops connect rotatable rotating shaft 3, and crowbar 1 activity is fixed in the rotating shaft 3;
Described rotating shaft 3 is the U type groove structure, and U type groove two ends are provided with the jack that flexibly connects with crowbar 1, and U type groove lower end is provided with the jack that flexibly connects with A-frame 4, and crowbar 1 activity is fixed in the U type groove of rotating shaft 3, can realize the movable up and down of crowbar 1;
Be provided with sleeve pipe 2 between described rotating shaft 3 and the crowbar 1, crowbar 1 outer pivot bush unit sleeve pipe 2, sleeve pipe 2 both sides captive joint rotating shafts 7, rotating shaft 7 is inserted in the set corresponding jack in U type groove two ends of rotating shaft 3, along with rotating shaft 7 is rotated in the jack of rotating shaft 3, sleeve pipe 2 drives crowbar 1 and realizes rotating up and down, the purpose of regulating crowbar 1 before and after crowbar 1 can stretch and reach in sleeve pipe 2;
Described A-frame 4 top captive joint rotating shafts 8, rotating shaft 8 is inserted in the set corresponding jack in U type groove lower end of rotating shaft 3, and along with rotating shaft 8 is rotated in the jack of rotating shaft 3, rotating shaft 3 drives crowbar 1 and realizes 360 ° of rotation rotations;
Distance between the U type groove bottom of the lower surface of described sleeve pipe 2 and rotating shaft 3 should guarantee the activity point of view that crowbar prizes up and down to greatest extent;
Be respectively equipped with the rack sleeve 5 that is used to regulate support height on three legs of described A-frame 4, be fixed on each leg by bolt of rear end plate 6.
A kind of triangular hoisting jack of the utility model, volume is little, and is in light weight, detachable transportation, need not any mechanical power can use, and is easy to use flexibly, can deal with any abominable operating environment, and convenient disassembly is time saving and energy saving.
Four, description of drawings
Fig. 1: a kind of triangular hoisting jack structural representation of the utility model;
Fig. 2: the structural representation that is connected of rotating shaft, sleeve pipe and A-frame;
Rotating shaft in the drawings, 1, crowbar, 2, sleeve pipe, 3, rotating shaft, 4, A-frame, 5, rack sleeve, 6, bolt of rear end plate, 7, rotating shaft, 8.
Five, the specific embodiment
Following with reference to accompanying drawing, provide the specific embodiment of the present utility model, be used for formation of the present utility model is further specified.
Embodiment
A kind of triangular hoisting jack of present embodiment comprises A-frame 4, crowbar 1, rotating shaft 3 with reference to Fig. 1-2, and rotating shaft 3 is the U type groove structure, and U type groove two ends are provided with the jack that flexibly connects with crowbar 1, and U type groove lower end is provided with the jack that flexibly connects with A-frame 4;
A-frame 4 by rotating shaft 8 flexibly connect can 360 ° of rotations rotating shaft 3, A-frame 4 top captive joint rotating shafts 8, rotating shaft 8 is inserted in the set corresponding jack in U type groove lower end of rotating shaft 3, and along with rotating shaft 8 is rotated in the jack of rotating shaft 3, rotating shaft 3 drives crowbar 1 and realizes 360 ° of rotation rotations;
Crowbar 1 outer pivot bush unit sleeve pipe 2, sleeve pipe 2 both sides captive joint rotating shafts 7, rotating shaft 7 is inserted in the set corresponding jack in U type groove two ends of rotating shaft 3, along with rotating shaft 7 is rotated in the jack of rotating shaft 3, sleeve pipe 2 drives crowbar 1 and realizes rotating up and down, the purpose of regulating crowbar 1 before and after crowbar 1 can stretch and reach in sleeve pipe 2; Be respectively equipped with the rack sleeve 5 that is used to regulate support height on three legs of A-frame 4, be fixed on each leg by bolt of rear end plate 6;
Distance between the U type groove bottom of the lower surface of sleeve pipe 2 and rotating shaft 3 should guarantee the activity point of view that crowbar prizes up and down to greatest extent.
During installation, at first A-frame 4 being put rack sleeve 5 carries out height adjustment and fixes, then crowbar 1 is inserted in the sleeve pipe 2, aim at the set jack insertion in two ends in the rotating shaft 3 by the rotating shaft 7 of sleeve pipe 2 both sides, crowbar 1 can rotate with rotating shaft 7 and realize prizing up and down this moment, again the set jack in U type groove lower end of rotating shaft 3 and the rotating shaft 8 on A-frame 4 tops are flexibly connected, realize that 360 ℃ of rotating shaft 3 circle round.
The triangular hoisting jack of present embodiment, volume is little, and is in light weight, detachable transportation, need not any mechanical power can use, and is easy to use flexibly, can deal with any abominable operating environment, and convenient disassembly is time saving and energy saving.
