Description
Technical field
The utility model belongs to crane technical field, and in particular to a kind of arm for heavy lift crane.
Background technology
Existing crane mainly includes panoramic table, support frame and arm, and arm is generally telescopic arm, i.e., including it is multiple can phase
To flexible arm joint, panoramic table is installed in the main body of crane, and support frame is installed on panoramic table, and arm is installed on support frame
On, support frame and arm can be rotated with panoramic table in Plane of rotation.Because crane will be whole in side operation need
Individual support frame and arm revolution, the revolution inertia of complete machine is big, and now the stability against overturning of crane is deteriorated, and works as windage
When the stability against overturning of crane can be made further to deteriorate, crane rollover possibility increase.
Utility model content
Based on this, in view of the above-mentioned problems, the utility model proposes a kind of arm for heavy lift crane, the letter of its structure
Single, stability is good, and structural strength is high, and anti-seismic performance is good, need not rotate whole arm during the operation of side, and reduction is toppled risk.
The technical solution of the utility model is：A kind of arm for heavy lift crane, including suspension rod, mutually ratcheting the
One gear and second gear and the first expansion link being sequentially connected, the second expansion link and the 3rd expansion link；Described first is flexible
Bar is provided with the first fixing axle and the second fixing axle, and the first fixing axle and the second fixing axle are vertical with the first expansion link；It is described
First gear is rotatably arranged in first fixing axle, and the suspension rod is fixed in first gear；The second gear can turn
Dynamicly in second fixing axle, the second fixing axle is provided with the first runner being fixedly connected with second gear；Described
Three expansion links are provided with the second runner corresponding with the first runner, and the first runner and the second runner are provided with tricing line.
By pulling tricing line to drive the first runner to rotate, and then second gear is driven to rotate, second gear drives first
Pinion rotation, and then drive suspension rod to rotate, side operation can be completed without rotating whole support and arm, avoids whole arm
Rotate and then trigger the risk of rollover.
As further improvement of the utility model, the suspension rod is provided with suspension hook.
As further improvement of the utility model, the thickness of the first gear is 4cm-6cm, the tooth in first gear
A length of 3cm-5cm.
As further improvement of the utility model, the thickness of the second gear and the thickness phase of the first gear
Together, the tooth length in second gear is identical with the tooth length in first gear.
On suspension rod on carry after weight, the ratcheting part stress between first gear and second gear is larger, and tooth length is shorter
When, unstable to skid, tooth length is longer then to reduce tooth intensity, and tine length is that 3cm-5cm is preferable, while transverse tooth thickness degree and whole tooth
The thickness of wheel is identical.
As further improvement of the utility model, the first gear and second gear use 35CrMo steel materials.
The beneficial effects of the utility model are：
(1) its is simple in construction, and stability is good, and structural strength is high, and anti-seismic performance is good；
(2) by pulling tricing line to drive the first runner to rotate, and then second gear is driven to rotate, second gear drives the
One pinion rotation, and then drive suspension rod to rotate, side operation can be completed without rotating whole arm, avoids whole arm from rotating
And then trigger the risk of rollover.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment：
As Figure 1-3, a kind of arm for heavy lift crane, including suspension rod 401, mutually ratcheting first gear
405 and second gear 406 and the first expansion link 402, the second expansion link 403 and the 3rd expansion link 404 that are sequentially connected；Institute
State the first expansion link 402 and be provided with the first fixing axle 407 and the second fixing axle 411, the first fixing axle 407 and the second fixing axle
411 is vertical with the first expansion link 402；The first gear 405 is rotatably arranged in first fixing axle 407, described
Suspension rod 401 is fixed in first gear 405；The second gear 406 is rotatably arranged in second fixing axle 411, the
Two fixing axles 411 are provided with the first runner 408 being fixedly connected with second gear 406；3rd expansion link 404 be provided with
Second runner 409 corresponding to first runner 408, the first runner 408 and the second runner 409 are provided with tricing line 53.
By pulling tricing line 53 to drive the first runner 408 to rotate, and then second gear 406 is driven to rotate, second gear
