The specific embodiment

Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.

This is novel to be a kind of mechanism of simple and reliable, lifting that can Rapid Realization, and the swing that lean on swing arm, swing arm oil cylinder specifically, plays the tower oil cylinder drives balladeur train and rises, falls, and finally realizes the lifting function of rig.

The core of this mechanism has reached the tower cylinder component by swing arm, swing arm oil cylinder and has formed.

Like Fig. 2, Fig. 3 and shown in Figure 4; The Kong Weiyu swing arm 2 of swing arm oil cylinder 31 upper ends is relative; Penetrate and couple together both through connecting bearing pin A1; The inner outer two groups of nuts in the right part of connection bearing pin A are screwed and are fixed, and inner nut 14 upper ends have the flat key groove and place flat key 17, and flat key has locking effect; Outer nut 16 is screwed and is mixed floor clip 15 again, and double like this protection is extraordinary fixes the end.Put card key II18 between the left part of connection bearing pin A and swing arm, be threaded the collar II19 in hole on the card key II outer cover, leaned on bolt and bullet pad to fix axle head again.

Like Fig. 5, shown in 6, connect bearing pin C10 cover Upper shaft sleeve I8 and penetrate bearing 3, swing arm 2 successively, right-hand member leans on two groups of nuts to fix, and inner nut 6 splines and flat key 7 is housed, and flat key has locking effect; Outer nut 4 is screwed and is mixed floor clip 5 again.Connect bearing pin C left end and put card key I11, have the collar I9 of screw on the card key outer cover, lean on bolt and bullet pad to fix again.Two bearings on the bearing pin of bottom are joined by size and to be welded in above the frame assembling the back.

Like Fig. 7, shown in 8, the connection bearing pin D28 that is with axle sleeve II29 is passed in swing arm oil cylinder bottom, and matching with bearing is connected, and the end is tightened with bolt and bullet pad and fixed.Bearing is joined by size and is welded on the frame.

Shown in figure 10, be connected bearing 35 with tower oil cylinder 27 upper end by connecting bearing pin D33, the end of bearing pin leans on back-up ring 32 to carry out axial restraint; The other end is installed flat key at axle head, in case the shotpin diameter of axle is to rotation.

As shown in Figure 9, be connected bearing 20 with tower oil cylinder 27 bottom by connecting bearing pin C21, an end that connects bearing pin C is with elastic collar 23, gland 24 and packing ring 25, bolt; Connect the bearing pin C other end and be equiped with flat key, in case the shotpin diameter of axle is to rotation.

Lifting process: when swing arm oil cylinder piston bar was boosted, swing arm had reached the tower oil cylinder and has and then carried out the rotation of cw circumference, and balladeur train is whole toward rising; When the downward indentation of piston rod of swing arm oil cylinder, swing arm has reached the tower oil cylinder and then to be carried out the conter clockwise circumference and rotates, and balladeur train is whole to descend.

Rotation process: when a tower oil cylinder piston bar was boosted, balladeur train will rotate counterclockwise, and rose; When piston rod down during indentation, balladeur train will clockwise rotate and descend.

What should explain at last is: the above is merely the embodiment of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
