Description
Technical field
The utility model relates to a kind of crawler crane, specifically a kind of crawler crane jib support structure, and comprises the crawler crane of this jib structure, belongs to crawler crane jib support structure technical field.
Background technology
Crawler crane is sailed with its overline capable of hoisting, ground comformability is good, 360 ° of comprehensive operations, jibs have the features such as multiple combination mode and are widely used in the occasions such as power construction, metallurgical construction, chemical industry construction, bridge construction, water conservancy construction.
Modern lifting is had higher requirement to weight-lifting equipment, the type that the identical configuration of tonnage is identical, hoisting crane is required larger work range, higher lifting altitude, wider scope of work, how to play larger potentiality when resource-constrained, be crawler crane developing direction from now on.
For widening the range of use of crawler crane, pursue the lifting altitude of larger operating radius and Geng Gao, present stage is realized by different jib array modes, develops single-side stand and fix auxiliary operating mode and the tower auxiliary operating mode of double bracket, as shown in Figure 1 to Figure 3 from principal arm operating mode.
As shown in Figure 2, auxiliary operating mode fixed by single-side stand is on the basis of principal arm operating mode, and add single-side stand, fixing auxiliary and front and back arm-tie thereof, between principal arm and fixing auxiliary, angle is fixed, and increases lifting altitude and operating radius with this.
As shown in Figure 3, the tower auxiliary operating mode of double bracket is on the basis of principal arm operating mode, add double bracket, tower auxiliary, front and back arm-tie and variable-amplitude steel wire rope system, because tower auxiliary self can change the elevation angle by variable-amplitude steel wire rope, therefore auxiliary operating mode is fixed relative to single-side stand, the swinging radius of the tower auxiliary operating mode of double bracket is larger, and lifting altitude is higher, and application is wider.
But the technological deficiency in prior art existing for crawler crane jib support structure is as follows:
1, single-side stand is fixed auxiliary operating mode due to the angle between principal arm and fixing auxiliary and is fixed, and only realize different operation heights and swinging radius by changing the principal arm elevation angle, the degree that scope of work increases is very limited.
2, the tower auxiliary of double bracket can principal arm and the dual luffing of tower auxiliary, there is wider scope of work comparatively speaking, but due to tower auxiliary features, need enough strong principal arm to support tower auxiliary, there is enough strong main frame to keep the stability of car load, if therefore the little tonnage caterpiller crane of less than 100 tons need be equipped with the increase of tower auxiliary operating mode cost and account for integral vehicle cost proportion very greatly, operating costs is high, and generally not advising increases.
3, for middle large-tonnage crawler crane, if need be equipped with tower auxiliary operating mode, need increase double bracket, tower auxiliary, front and back arm-tie, variable-amplitude steel wire rope system, relative usage cost is high, and constructing operation is relative complex also.
4, little tonnage caterpiller crane is used, when increasing tower auxiliary operating mode difficulty, propose again to meet simultaneously higher wider scope of work when, user only uses more large-tonnage crawler crane or use more large-tonnage wheel crane etc. instead instead, use cost increases greatly, and resource utilization is low.
