Working principle:
Pick housing of pneumatic pick 1 and pick rod 2 constitute conventional pneumatic pick carry out using.And pick housing of pneumatic pick 1 is consolidated using assembly fixed mechanism
It is scheduled on small kickstand 3.Specifically, being fixedly set on pick housing of pneumatic pick 1 using fixing hoop 7, and make the L on fixing hoop 7
Type supports in the assembly slot 11 on snap-gauge plugging in fitting fixed block 8, and fixing bolt 14 is recycled to pass through limit 12 He of pilot hole
Long range pilot hole 13 carries out assembly fixation, will then be fixed between pick housing of pneumatic pick 1 and small kickstand 3.It is needing to move
When cylinder body 1 and pick rod 2, then the lower end for needing to make movable pulley 6 be moved to mounting bracket 4 using hand-operated lifting driving mechanism,
So that movable pulley 6 is supported and move whole device, and is equipped with the arc handle of anti-skidding soft set 35 using mounting bracket 4
Hand 34 is pulled.Specifically, discharging pulling handle 20 using the limit fixed cell in hand-operated lifting driving mechanism, that is, pass through
Pull handle 26 pulls the bar 24 that is slidably connected, and so that magnet ring 27 is left pulling handle 20, while driving the limited post on limit plate 25
28 leave the limiting groove 29 of 4 upper end of mounting bracket, and pulling handle 20 is able to drive 18 turns of L-type rotary supporting rod at this time
It is dynamic, it is aligned at the limiting groove 29 of 4 lower end of mounting bracket until 20 bottom of pulling handle turns to limited post 28, and make limited post
In 28 insertion limiting grooves 29, at this time because pulling handle 20 is metal handle, magnet ring 27 is fixed on pulling handle by magnetism
Stablize limited post 28 in insertion limiting groove 29, will also be driven during L-type rotary supporting rod 18 rotates
Horizontal supporting shaft 19 rotates, because being mounted with No. two fixing bearings 22 and No.1 on horizontal supporting shaft 19 and horizontal rotating shaft 5 respectively
Fixing bearing 21 makes level by the connection of the supporting linkage 23 between No. two fixing bearings 22 and No.1 fixing bearing 21
Support shaft 19 is in the rotation by support level shaft 5 to bottom offset, until horizontal rotating shaft 5 drives movable pulley 6 to be moved to peace
The lower end of dress bracket 4 is supported and moves to whole device, during this, passes through sliding support mechanism support level shaft
5 and carry out slide displacement.Specifically, making the fixed horizontal rotating shaft 5 of the rolling bearing 17 in circular ring shape sliding block 16, and utilize rotation axis
Holding 17 can be such that horizontal rotating shaft 5 and movable pulley 6 is rotated.Wherein circular ring shape sliding block 16 can be along 4 inside of mounting bracket
Vertical chute 15 carry out slide displacement, then realize the displacement of horizontal rotating shaft 5 and movable pulley 6.Then need to start pneumatic pick
Movable pulley 6 is then moved to the upper end of mounting bracket 4, makes movable pulley 6 far from ground by cylinder body 1 when carrying out work and use,
And it is worked using shock-absorbing support mechanism supports ground, and play the role of damping, and using mounting bracket 4 equipped with anti-skidding
34 raising apparatus of bowhandle of soft set 35 carry out using.When so that movable pulley 6 is moved to the upper end of mounting bracket 4,
Also it will be operated by hand-operated lifting driving mechanism.Specifically, pulling handle 20 is discharged using limit fixed cell, using pulling
Dynamic handle 20 drives L-type rotary supporting rod 18 and horizontal supporting shaft 19 to be rotated, and then connects in the support of supporting linkage 23
It connects lower pulling horizontal rotating shaft 5 to rise, then movable pulley 6 is driven to rise, and again by limit fixed cell to pulling handle 20
It is fixed, then the position of movable pulley 6 is fixed.And it is being worked using shock-absorbing support mechanism supports ground
When, the conical shell pedestal 33 equipped with rubber antiskid circle 36 contacts ground, and the vibration generated in pneumatic pick work will be by damping
Spring 31 carries out damping, and when length variation occurs for damping spring 31, support post 30 is opposite in 32 inside of annular slab
Telescopic moving ensure that damping spring 31 will not be bent, also ensure the stability of support device.Wherein rubber antiskid circle
36 play certain anti-skidding effect.
Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or
It changes still within the protection scope of the invention.
