Spigot surface；The spigot surface of sliding block on the interior arm support is embedded in interior arm support groove, the spigot surface of the sliding block on boom
It is embedded in boom through hole, the supporting surface of sliding block is located between boom inwall and interior arm support outer wall；Lead in the boom
Hole external seal is fixed with shrouding, and fastener is provided with least two shroudings；The fastener includes being arranged on shrouding
Upper, the inner regulation jackscrew for being against slider guide face outer end；It is provided with the regulation jackscrew and closes mother.
It is further：The interior arm support is hollow stem, and oil cylinder is provided with interior arm support；The cylinder block upper end passes through
Upper pin is hinged with boom upper end, and cylinder piston rod lower end is hinged by lower bearing pin and interior arm support lower end.
Support plate is also hinged with the lower bearing pin.
The boom and interior arm support are hollow square poles；The fastener is provided with two altogether, intersects 90 ° of cloth
Put.
Compared with prior art, the beneficial effects of the invention are as follows：The bolt and adjust pad of fixed sliding block are eliminated, is improved
The installation of sliding block and the structure for adjusting gap, the efficiency in user's maintenance and support frame gap is substantially increased, it is strong to reduce work
Degree, has saved cost；Integrated operation is simple, it is safe and reliable, be easily achieved；Suitable for the work of most of installation telescopic jib structures
Journey machinery or other category product equipment, are widely used.

Embodiment
It is the specific embodiment of the present invention below, in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1 to Figure 2, a kind of telescopic jib sliding block is fixed and governor motion, during boom 1 and interior arm support 6 are
Empty square bar, four angles are fillet；The interior slip cap of arm support 6 is in boom 1, outside the inwall of boom 1 and interior arm support 6
Gap is left between wall.The surrounding of the interior upper end of arm support 6 is provided with multiple uniform grooves, in the present embodiment on interior 6 each face of arm support
A groove is offered, opens up four grooves altogether.The surrounding of the lower end of boom 1 is provided with multiple uniform through holes, in the present embodiment
Boom offers a through hole on 1 each face, opens up four through holes altogether.
In conjunction with shown in Fig. 4, a sliding block 8 is separately installed with the interior groove of arm support 6 and the through hole of boom 1.Sliding block 8 wraps
A supporting surface 8-1 is included, supporting surface 8-1 sides are fixed with the spigot surface 8-2 of protrusion.The spigot surface 8- of sliding block 8 on interior arm support 6
2 are embedded in the interior groove of arm support 6, and the spigot surface 8-2 of the sliding block 8 on boom 1 is embedded in the through hole of boom 1, the branch of sliding block 8
Support face 8-1 is located between the inwall of boom 1 and the outer wall of interior arm support 6.Sliding block 8 on interior arm support 6 without regulation, it is main rise support and
Improve and slide efficiency effect；The top shoe 8 of boom 1 needs to adjust, and efficiency work is slided in main support, regulation gap and raising
With.
Shrouding 2 is fixed with by the sealing of fixing bolt 4 in conjunction with shown in Fig. 3, the through hole of boom 1 is outer, shrouding 2 can play
Dustproof effect.Fastener is installed at least two shroudings 2, fastener is used for adjust the sliding block 8 on boom 1；
Fastener is provided with two altogether in the present embodiment, intersects 90 ° of arrangements；, the fastening different with the shape of interior arm support 6 according to boom 1
Device number and the equal adaptability adjustment of angle of intersection.Fastener is included on shrouding 2, the inner is against sliding block 8 and is oriented to
The regulation jackscrew 5 of face 8-2 outer ends；It is provided with regulation jackscrew 5 and closes mother 10.
Relative motion between boom 1 and interior arm support 6 provides power by oil cylinder 9.The cylinder body upper end of oil cylinder 9 passes through upper pin
7 are hinged with the upper end of boom 1, and the piston-rod lower end of oil cylinder 9 is hinged by lower bearing pin 11 and the interior lower end of arm support 6.On lower bearing pin 11 also
It is hinged with support plate 3.
During practical operation operation：
When boom 1 and interior arm support 6 due to sliding block 8 wears and when gap increases, pass through spanner and rotate regulation jackscrew on shrouding 3
5, regulation jackscrew 5 is promoted sliding block 8 when inwardly adjusting, then sliding block 8 is promoted interior arm support 6, so as to eliminate interior arm support 6 and boom
Gap between 1, by closing female 10 lock up gap after the completion of adjustment.
By this regulative mode, efficiency far is higher than increasing adjust pad come by way of adjusting gap the present invention,
And sliding block installation is not required to any fastener, the efficiency of sliding block demolition, installation and the maintenance of telescopic jib gap is greatly improved, is saved
Cost.
