Description

Multi-functional jack drawing device

Technical field

The present invention relates to a kind of jack device, have the function of drawing especially simultaneously.

Background technology

At present, it is several that jack has mechanical jack and hydraulic jack etc.Hydraulic jack is used pascal's principle, and production operation is simple and easy.The lifting screw theory of machines, back and forth to pull handle, pusher dog promptly promotes the revolution of ratchet gap, and bevel pinion drives large bevel gear, makes the rotation of weight lifting screw rod, thereby makes jacking sleeve obtain to hoist or descend, and reaches the function of lifting pulling force.These jacks all do not have directly to produce the function of pulling force.

ZL200710052939.2, Granted publication CN100552142C have announced a kind of trussed steel beam closing jacking-drawing device, are the functions of using single " top " of jack, realize pushing up by the different positions of top workpiece and draw function.

In the activity in production, often need jacking-drawing device; Moreover, safety misadventure often takes place in daily life and the activity in production, particularly in today that automobile quantity increases severely, the traffic accident accident is more and more, and the safety misadventure scene that causes comprising traffic accident has personnel or visual plant, goods and materials to need rescue.Therefore, be necessary to design a kind of jacking-drawing device, be used for activities such as production and rescue.

Summary of the invention

The purpose of this invention is to provide a kind of multi-functional jack drawing device.

The technical solution adopted for the present invention to solve the technical problems is: mainly comprise ratchet group, bevel pinion, nut, screw mandrel, top draw piece, sleeve, large bevel gear, bearing set, housing, bearing seat, nut, bottom nut, attaching parts, it is characterized in that: have a unit at least, bearing set and bearing seat are established in described unit, the unit is under the state on top, one shaft strength is arranged in the described bearing set, the unit under the state that draws, another shaft strength of described bearing set.

Device can be established two unit or three unit, is provided with attaching parts between described unit and the unit.

Large bevel gear, bearing, bearing seat, bearing are set in screw mandrel successively, and described bearing lays respectively at the two ends of bearing seat.

Described wire rod thread is a square thread; Described bearing is surface bearing or tapering bearing.

Described top draw piece is fluted and establish draw ring, and described base is fluted and establish draw ring; Described draw ring is installed on top draw piece and base respectively with bearing pin, and described draw ring can rotate around bearing pin, and can be hidden in the described groove.

Described housing Lian Lama cover realizes drawing the horse function.

Saddle in described screw mandrel connects, interior saddle connects motor cabinet, realizes adjusting the motor position function.

Described housing and screw mandrel connect shearing blade respectively, realize shearing function.

The invention has the beneficial effects as follows that by increasing by one group of bearing and bearing seat, the present invention has realized " top " and " drawing " function, launch draw ring, can make very heavy entering " draw " state, hide draw ring, make device can enter " top " state.If the employing thrust roller bearing, the scope of device holding capacity can reach the 3-500 ton, can realize drawing functions such as horse, scissors, electric machine speed regulation, and simple in structure, device volume is little, and function is many.Can be used for machinery production, bridge construction, communications and transportation, building engineering and rescue etc.

The specific embodiment

Referring to Fig. 1, present embodiment is an one unit, comprises ratchet group 101, bevel pinion 102, pushes up and draw nut 103, screw mandrel 104, draw ring 105, sleeve 107, large bevel gear 108, bearing

set

109 and 111, housing 110, bearing seat 112, nut 113, bottom nut 114, draw ring 115.Large bevel gear 108, bearing 109, bearing seat 112, bearing 111 are set in screw mandrel 104 successively, and bearing 109 and bearing 110 lay respectively at the two ends of bearing seat.Screw mandrel 104 is a square thread, and bearing 109 and bearing 110 can be tapering bearing or thrust roller bearing (GB/T4663-1994).Machined grooves on the base 112, draw ring 115a is installed on the base 112 by bearing pin, and rotation draw ring 115a can hide and launch draw ring, and when hiding, present embodiment can be made " top " usefulness, can do " drawing " during expansion and use.The unit is under the state on " top ", and bearing centre bearer 109 is stressed, and the unit is under the state of " drawing ", and bearing 110 is stressed.Large bevel gear 8 is driven by bevel pinion, and bevel pinion provides two-way rotational force by the ratchet group.

Referring to Fig. 2, present embodiment is established two unit, and the base 112 of two unit connects by attaching parts 115b, and 115b is a sleeve-like, and screw thread is arranged, and it is bigger that square thread can bear pulling force.Present embodiment is two-way jack drawing device.

Referring to Fig. 3, present embodiment is established three unit, is provided with attaching parts 115c between unit and the unit, and 115C as shown in Figure 8.Present embodiment is a three-dimensional jack drawing device.
