The technical solution of utility model, and the scope of protection of the utility model cannot be limited with this.
The utility model is a kind of reinforced boom system of multi-arm frame combined type, breaks previous single, double boom system
Design Thinking, requirement that can be according to complete machine to boom system bearing capacity extend to multi-arm frame combined system.Fig. 5 is three arm supports
Structural schematic diagram reinforces section by two coxopodite arms 3, connection section I4, connection section II6, connection section III7, several middle nodes 5, two
Arm 9 and three arm heads 8 form.Three arm heads 8 respectively connect several middle nodes 5 all the way, and on two wings of both sides
The end of middle node 5 is also respectively connected with a coxopodite arm 3, and passes through parallel connection section III7, connection between three road middle nodes 5
II6, connection section I4 are saved across connection.Connection section III7 from arm head 8 to 3 direction of coxopodite arm that set gradually from, connection section II6, even
Section I4 is met, length gradually increases successively.Wherein, need to a length be set most at the tie point between coxopodite arm 3 and middle node 5
Long connection section, the connection section intersect with positioned at intermediate 5 end of middle node connection all the way simultaneously, in the present embodiment using
Connection section I4；In other embodiments, connection section can be increased and decreased as needed.The end of coxopodite arm 3 with positioned at centre one
By reinforcing the connection intersection of joint arm 9 between 5 end of middle node on road.Entire boom system is long by increasing and decreasing middle node progress arm support
Short transformation, the middle node between multi-arm frame use identical arm joint structure, arm joint utilization rate high；It is dress between connection section and each arm support
With relationship, multi-arm frame is connected into an entirety, makes uniform force between each arm support, if being increased according to the practical combinations situation of arm support
Dry section connection section, to enhance the stability of arm support；The reinforcement joint arm 9 of bottom and coxopodite arm 3 and to connect section I 4 be assembly connection, it is main
If multi-arm frame is unified for an entirety, be transmitted to arm support stress and uniformly host so that host associated structural component by
Power is clear.
Fig. 6 is to be extended to both arms frame structural schematic diagram, need to only remove bottom and reinforce section, intermediate arm support middle node and arm head
Remove one, only by each connection several middle nodes 5 and the coxopodite arm 3 all the way of two arm heads 8, and two-way middle node 5 it
Between by parallel connection section III7, connection section II6, connection section I4 across connection.It is set successively from arm head 8 to 3 direction of coxopodite arm
Connection section III7, connection section II6, the connection section I4 set, length gradually increase successively, make double jib structure generally front end shapes
At spacing it is smaller, rear end formed spacing it is larger, enhance the stability of arm support.Wherein, in coxopodite arm 3 and 5 end of middle node
Between tie point at a length longest connection section need to be set, such as the connection section I4 used in the present embodiment.In other implementations
In example, connecting the quantity of section can be increased and decreased according to actual needs.Entire boom system is long by increasing and decreasing middle node progress arm support
Short transformation, the middle node between multi-arm frame use identical arm joint structure.Fig. 7 is to be extended to single arm support structural schematic diagram, is only needed
Retain a coxopodite arm 3, several section middle nodes 5 and an arm head 8.
Boom system main chord uses pipe pattern in the utility model, and square tube, rectangular tube or other equally may be used
Shape tube reaches the utility model aim；Three arm supports are only extended in the utility model, can be expanded according to lifting demand
Exhibition is that more arm supports combine.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without deviating from the technical principle of the utility model, several improvement and deformations can also be made, these change
The scope of protection of the utility model is also should be regarded as into deformation.
