Description
Technical field
This utility model relates to crane accessory field, is specially a kind of telescopic crane boom.
Background technology
The telescopic arm structure of existing crane is complicated, and in use, telescopic process is more slow, affects lifting work
Efficiency, and existing telescopic crane boom is bulky, can expend more energy during flexible, increases carbon row
Put, do not meet the theme of current social energy-conserving and environment-protective.
Utility model content
The purpose of this utility model is to provide a kind of telescopic crane boom, with asking of solving to propose in above-mentioned background technology
Topic.
For achieving the above object, this utility model following technical scheme of offer: a kind of telescopic crane boom, including installing
Ring, the outside of described mounting ring is fixing with the lower end of master arm to be connected, under the upper end of described master arm and middle support arm
Hold hinged, between left side central portion and the left side central portion of middle support arm of described master arm, be hinged with the first hydraulic stem, described in
The upper end of support arm is hinged with the lower end of upper support arm, the right side central of described middle support arm and the right side central of upper support arm it
Between be hinged with the second hydraulic stem, the limit, the left and right sides of described master arm, middle support arm and upper support arm has been fixedly connected with and has added
Strong rib, the upper end of described upper support arm is rotatably connected with playing accent rotating shaft, and the outer end of described accent rotating shaft rotates with playing accent
Connecting, be fixedly connected with pulley support frame on the downside of the outer end of described accent, the outside of described pulley support frame is provided with hoisting line
Groove.
Preferably, the end to end S-type arrangement of described master arm, middle support arm and upper support arm.
Preferably, described reinforcement rib is strip structure.
Preferably, described pulley support frame is rectangular configuration and circular configuration is spliced.
Compared with prior art, the beneficial effects of the utility model are: this Telescopic boom structure of crane is simple, by using
Master arm, middle support arm and upper support arm, the mode that three is connected, it is possible to the effective length increasing telescopic crane boom,
By adding the first hydraulic stem and the second hydraulic stem structure, it is possible to trailed by telescopic arm rapidly, enter work shape rapidly
State, therefore improves work efficiency, strengthens rib by adding, by increasing capacitance it is possible to increase intensity of the present utility model, thus simplifies crane and stretch
The volume of contracting arm, it is possible to reduce unnecessary energy resource consumption, therefore, it is possible to play the effect of certain energy-saving and emission-reduction, total comes
Say, this utility model simple in construction, it is possible to increase lifting work efficiency, and carbon emission can be reduced, be suitable for promoting the use of.
Accompanying drawing explanation
Fig. 1 is this utility model structure top view；
Fig. 2 is this utility model structure left view；
Fig. 3 is for strengthening rib structural representation；
Fig. 4 is lifting header structure schematic diagram.
In figure: 1 mounting ring, 2 master arms, support arm in 3,4 first hydraulic stems, support arm on 5,6 second hydraulic stems, 7

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to Fig. 1-4, this utility model provides a kind of technical scheme: a kind of telescopic crane boom, including mounting ring 1,
The outside of mounting ring 1 is fixing with the lower end of master arm 2 to be connected, and the upper end of master arm 2 is hinged with the lower end of middle support arm 3,
The first hydraulic stem 4, the upper end of middle support arm 3 it is hinged with between left side central portion and the left side central portion of middle support arm 3 of master arm 2
Hinged with the lower end of upper support arm 5, it is hinged with second between right side central and the right side central of upper support arm 5 of middle support arm 3
Hydraulic stem 6, the end to end S-type arrangement of master arm 2, middle support arm 3 and upper support arm 5, this structure, it is possible to effectively save
Save the volume of telescopic arm, thus save space, and the speed that telescopic arm trails can be accelerated, improve the work effect of lifting
Rate, the limit, the left and right sides of master arm 2, middle support arm 3 and upper support arm 5 has been fixedly connected with reinforcement rib 9, and strengthening rib 9 is bar
Shape structure, strengthens rib 9 and can increase intensity of the present utility model, extend the service life of crane gear, the upper end of upper support arm 5
Being rotatably connected with playing accent rotating shaft 7, the outer end playing accent rotating shaft 7 is rotatably connected with playing accent 8, rises on the downside of the outer end of accent 8 solid
Determining connection has pulley support frame 10, the outside of pulley support frame 10 to be provided with lifting grooving 11, and pulley support frame 10 is rectangular configuration
Being spliced with circular configuration, this structure is more firm, it is not easy to rupture during using, by increasing capacitance it is possible to increase crane gear
Stability.
Embodiment the most of the present utility model, for the ordinary skill in the art,
It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair
Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
