Specific embodiment
Below in conjunction with the accompanying drawings and pass through embodiment the utility model is described in further detail, following embodiment is pair
The explanation of the utility model and the utility model is not limited to following embodiment.
Embodiment.
Referring to Fig. 1 to Fig. 5, the present embodiment presses horse for the novel hydraulic of installing and dismounting derrick crane axis pin, including hand
Hydrodynamic pressure pumping plant 1, manual lever 2 and manual pump pressure display module 3, high-pressure rubber oil pipe 4, hydraulic jack 5 and adjustable
Formula cross frame group 6, manual pump pressure display module 3 is assemblied on hand-hydraulic pumping plant 1, and hand-hydraulic pumping plant 1 is provided with hand
Dynamic operating lever 2, hydraulic jack 5 are connect by the high-pressure rubber oil pipe 4 with hand-hydraulic pumping plant 1, adjustable cross frame group 6
It is connect with hydraulic jack 5.
The adjustable cross frame group 6 of the present embodiment include two mutually isostructural adjustable cross frames 61, this two
Adjustable cross frame 61 is movably connected by four adjusting bolt groups 7；Two adjustable 61 spacing of cross frame are adjusted.
Screw thread is provided in the hydraulic jack 5 of the present embodiment, adjustable cross frame group 6 passes through screw thread and hydraulic jack
Piston rod one end connection on top 5.
The through-hole diameter of the adjustable cross frame group 6 of the present embodiment is more than the diameter of axis pin 9；Hydraulic jack 5 uses
Bidirectional hydraulic jack 5.
The present embodiment installation axis pin 9 specific implementation step be：Hydraulic pressure is first pressed into the adjustable cross frame group 6 of horse and is needed
The axis pin 9 of loading is fixed on adjusting bolt group 7 on crane arm lower boom 8, it is desirable that through-hole, the pin of adjustable cross frame group 6
Axis 9, the pin shaft hole of crane arm lower boom 8 are concentric；After fixing, can back and forth it shake on hand-hydraulic pumping plant 1 by a small margin
Manual lever 2, at this time hydraulic jack 5 can complete jacking therewith, while axis pin 9 is pushed into pin shaft hole, such as Fig. 5 institutes
Show；Axis pin 9 is longer at this, and after hydraulic jack 5 completes one stroke, axis pin 9 does not push away in people's pin shaft hole completely, at this time can be first
5 piston rod of hydraulic jack is withdrawn, adjusts the adjusting spiral shell group 7 in adjustable cross frame group 6 manually until adjustable cross-shaped
Frame group 6 fixes again, can carry out secondary jacking in this way.When encountering compared with long pin shaft 9, this operation is repeated until axis pin 9
It heads into completely；When the pressure gauge on manual pump pressure display module 3 reaches maximum value, axis pin 9 heads into completely；Dismounting is fixed on
Adjustable cross frame group 6 at crane arm lower boom 8, so far, hydraulic pressure pressure horse installation jib for tower crane lower boom 8
The work of axis pin 9 at place is completed.
Two adjustable 61 angles of cross frame of the present embodiment are into a special angle, and length is adjustable during bolt fastening,
The installation of the applicable multiple position axis pins 9 of Multiple Type derrick crane.
The tonnage of hydraulic jack 5 that the present embodiment is selected, stroke, piston rod diameter be suitble to jacking and a variety of rulers of ejection
The axis pin 9 of very little specification has versatility in derrick crane.
Operation principle：Adjustable cross frame group 6 coordinates 7 fixed hydraulic jack 5 of adjusting bolt group, recycles hydraulic pressure thousand
Jin pushes up 5 pressure generated to mount and dismount the larger axis pin 9 of derrick crane；As long as adjustable cross is first fixed during operation
The jacking and ejection of axis pin 9 can be realized in stent group 6, then the front and rear manual lever 2 swung by a small margin on manual pump station.
During work, two adjustable cross frames 61 coordinate adjusting bolt group 7 to be fixed in derrick crane agent structure,
Hydraulic jack 5 is driven using hand-hydraulic pumping plant 1, axis pin 9 is pushed into or released using the pressure of hydraulic jack 5.
The present embodiment solves time-consuming and laborious, working at height danger during installation and removal derrick crane axis pin 9, engineering
Progress is slow, and when encountering big axis pin 9, the artificial mode of pounding of hammering into shape is difficult the practical problems such as installing and dismounting.
By above-mentioned elaboration, those skilled in the art can implement.
Furthermore, it is necessary to illustrate, the specific embodiment described in this specification, the shape of parts and components is named
Claiming etc. can be different, described in this specification above content is only to the utility model structure example explanation.
