Abstract
The utility model relates to a mechanical jacking device, particularly a wheel type shears frame lifting jack. The utility model is mainly composed of a screw rod, an upper bracket, a lower bracket, an upper supporting rod, a lower supporting rod, a supporting hinge seat arranged on the screw rod, a moving supporting hinge seat, a shears-shaped supporting frame which is connected among the upper and the lower supporting rod, the supporting hinge beat and the moving supporting hinge seat and a wheel which is connected under the lower bracket or a rotary disc type base with wheels. The utility model has the characteristics of small size, wide lifting ranges, convenient move and easy positioning.
Description
The utility model belongs to jacking machinery, especially relates to a kind of wheeled shear shank jack.
The mechanical type jack of known technology, be typically the most by screw mandrel, upper bracket, lower bracket, upper bracket, lower bracket, be connected in the last lower fulcrum bar free bearing of screw mandrel one end, be connected in be meshed with screw mandrel on the screw mandrel other end on, lower fulcrum bar moves free bearing and forms, upper rack posts two ends respectively with lower bracket, last lower fulcrum bar is hinged mutually, handle during use on the rotary screw, make be meshed on the screw mandrel other end on, the lower fulcrum bar free bearing is on the other end, lower fulcrum bar free bearing move toward one another, thereby lower fulcrum bar rotates in the drive, power is upwards shored in generation, the jack-up object is then opposite when unloading.The jack of this kind form, because lower bracket is a base-like, last lower fulcrum bar is the single-stage bar, and the height of expansion is low, and moving resistance is big, uses inconvenient.
The purpose of this utility model is to provide a kind of jacking amplitude big, moves to be easy to wheeled shear shank jack.
Realize that the purpose of this utility model technical scheme is such: by screw mandrel 1, upper rack posts 2, lower fulcrum bar 3, upper bracket 4, lower bracket 5, be located at support free bearing 6 on screw mandrel one end and the band negative thread on the other end and screw mandrel ingear move support mechanical type jack that free bearing 7 etc. forms on, lower fulcrum bar and last, be provided with scissors shape bracing frame 8 between the lower fulcrum bar free bearing, this scissors shape bracing frame 8 is formed in the center cross-articulation by identical gangbar, be one or more levels combination, its four terminations respectively with upper rack posts 1, lower fulcrum bar 2, support free bearing 6, moving support free bearing 7 is hinged; And the lower bracket 5 of this jack is provided with wheel 9, perhaps is provided with the rotating disc type base 10 of band wheel, and this rotating disc type base 10 also can be made of rotating disk 11, floor board framing 12, wheel 9, track adjusting wheel 13 certainly, is connected with the below of lower bracket 5.
Wheeled shear shank jack of the present utility model is compared with mechanical type jack in the past, owing to increased telescopic jacking frame, the jacking amplitude is big, and lower bracket is provided with wheel or adds the rotating disc type base, conveniently moving, and the location is easily.
Description of drawings
Fig. 1 is the front view of the utility model embodiment
Fig. 2 is the birds-eye view of the utility model embodiment
Fig. 3 is the block diagram of the utility model embodiment
Below in conjunction with accompanying drawing the utility model is further described
Shown in Fig. 3, wheeled shear shank jack of the present utility model, has a horizontally disposed screw mandrel 1, one end of this screw mandrel 1 is a screw thread, other end end is part back-up ring 1A that extends out and the quadrangular section 1C that is connected handle 1B, supporting free bearing 6 is sleeved on the screw mandrel 1 adjacent in back-up ring 1A side, move support free bearing 7 and be provided with the other end place that negative thread is engaged on screw mandrel 1, lower bracket 5, lower fulcrum bar 3, mobile support free bearing 7 on the screw mandrel 1, ground supports free bearing 6, upper bracket 4, upper rack posts 2, and the hinge that the overlaps scissors shape bracing frame 8 that is unified into " X " shape is according to the mode of two power bars hinge connection mutually each other.The below of lower bracket 5 then also is provided with rotating disc type base 10, its floor board framing 12 that has two wheels 9 and a track adjusting wheel 13 that links together by rotating disk 11, with rotating disk 11 is constituted, shown in Fig. 3 is the handle 1D that links to each other with screw mandrel 1 end, and the square hole on this handle 1D end is that the quadrangular section 1C with screw mandrel 1 termination is complementary.
During use, should be pushed into the order position by wheeled shear shank jack, and adjust the position by rotary base, the handle 1D on the rotary screw rod can make upper bracket 4 rise until with weight jack-up again.During unloading, as long as contrarotation handle 1D is just passable.
