Cylinder pressure provides hydraulic oil.
Structure when described telescopic jib 11 is fully deployed as shown in Figure 7 (the not shown guard netting of in figure), telescopic jib
The 11 multilevel arm bodies including ecto-entad socket setting, are socketed to form by four sections of arm body ecto-entads in the present embodiment, often step by step
Section arm body is made by square tube, and wherein the cross sectional dimensions of outermost layer arm body 11-1 are maximum, the cross section of innermost layer arm body 11-2
Size is minimum.It is provided with hydraulic jack, the hydraulic thrust of hydraulic jack front end in the inner chamber of outermost layer arm body 11-1 of telescopic jib 11
Bar is connected with innermost layer arm body 11-2, telescopic arm 11 can be controlled to elongate or shorten by controlling moving forward and backward of hydraulic push rod.
It is respectively provided with a pulley on the front end top surface of the rear end top surface of outermost layer arm body 11-1 of telescopic jib and innermost layer arm body 11-2
19, the aerial condutor setting up is needed for support.
As shown in figure 8, being respectively welded the 11-3 that picks up the ears on the left and right side of rear and front end of outermost layer arm body 11-1, its
Also it is welded with, on the left and right side of remaining every section of arm body front end, the 11-3 that picks up the ears.The side of every section of arm body, the lower section picked up the ears also are welded with
One auxiliary is picked up the ears, and the length that described auxiliary the is picked up the ears length picked up the ears corresponding with above it is corresponding.The 11-3 that picks up the ears is by square tube
Make, its length direction is perpendicular with the length direction of telescopic jib.One end of each 11-3 that picks up the ears is welded on arm body, another
The pin-and-hole that end setting is arranged in a vertical direction.Pass through bearing pin 12-5 hinged yaw bar 12, institute in the pin-and-hole of 11-3 end of picking up the ears
State yaw bar 12 to rotate around bearing pin 12-5, launch to the outside away from telescopic jib.Pick up the ears on 11-3 and yaw bar 12
Be equipped with location hole 12-4, when yaw bar 12 turns to the position perpendicular with telescopic jib, pick up the ears on location hole and horizontal stroke
Location hole on fork is corresponding to be overlapped, and now fills alignment pin in location hole 12-4 interpolation, yaw bar 12 is fixed with the 11-3 that picks up the ears
Connect.
, away from one end setting connecting plate picked up the ears, the steel plate that described connecting plate is arranged for vertical direction, even for yaw bar 12
The guardrail 20 that a horizontal hinge arranges a long rod is passed through on the top of fishplate bar, and the bottom of guardrail 20 and connecting plate are arranged mutually
Match limits guardrail 20 lock pin holes vertical with yaw bar 12.The operation principle of lock pin holes and yaw bar with pick up the ears it
Between location hole similar with alignment pin, when yaw bar launches, guardrail can be vertically upright, hangs down with the axis direction phase of yaw bar
Directly；When yaw bar withdraws near telescopic jib, guardrail is rotated down and keeps flat on yaw bar.
Bracket is set in the lower section of yaw bar 12, for strengthening the weight capacity of yaw bar.Described bracket includes one and erects
To a pole 12-3 and oblique fulcrum bar 12-1.The upper end of vertical pole 12-3 is fixing even near the one end picked up the ears with yaw bar 12
Connect, the lower end of vertical pole 12-3 is hinged on auxiliary picks up the ears.Bolt and vertical pole 12-3 are passed through in one end of oblique fulcrum bar 12-1
Lower end be connected, the other end is bolted away from the one end picked up the ears with yaw bar 12.
Yaw bar 12 in the present embodiment is made of steel pipe, and yaw bar 12 is evenly equipped with some draw ring 12- along its length
2, draw ring 12-2 include small one and large one two annulus that the figure of eight is fixedly installed into, and wherein large circle lock ring is set in yaw bar
On 12 excircle, small circle ring is located at the lower section of yaw bar 12.Guard netting is the net being compiled into by high-strength nylon rope, protection
