Abstract

The utility model discloses a main jib nose for the track crane. The whole jib nose is welded by two groups of triangular high strength steel pipe structures (1 and 3) through steel pipes to form a main structure body; the steel pipes and a forming thin plate form a box body (4) on the lower plane of the main structure body, and the box body (4) is taken as the suspension point of a hoisting pulley block (8); the hoisting pulley block (8) is supported by two groups of triangular draw plate structures (5), two pin holes on the triangular draw plate structures are connected with the suspension point of the box body (4) on the lower plane of the jib nose structure, a corner at the lower part is taken as the ground supporting point (6) of the main jib, and the middle is connected through the main shaft (7) of the hoisting pulley block (8). The utility model is the main jib nose for the track crane, which has the advantages that under the circumstance that other parameters of the whole crane is invariable, the bearing capacity is strong, the structure is simple, the weight is extremely light, the stability and the hoisting performance of the whole crane are improved, and simultaneously the process requirement is low.

Description

A kind of crawler crane principal arm arm head
Technical field
The utility model relates to a kind of crawler crane, particularly relates to a kind of crawler crane principal arm arm head.
Background technology
Present stage, the principal arm arm head (tower head) of crawler crane was the direct stress members of lift heavy, need install and fix the anti-rear pole of auxiliary, tower auxiliary and auxiliary, stressed big and complex structure, and design difficulty is big, and representative type version is seen Fig. 3 and Fig. 4 at present.There is the weak point that tower auxiliary and sway bar can not be installed in this structure of Fig. 1, also must the special arm head of configuration when needing tower auxiliary; Second weak point is Heavy Weight, reduced complete machine stability and lifting performance.It is complex structure that there is weak point in this structure of Fig. 2, the technological requirement height; Second weak point also is Heavy Weight, reduced complete machine stability and lifting performance.
Along with crawler crane constantly develops, requirement to lifting performance and technology improves constantly, and the cost requirement is high, this contradiction has greatly limited the development of crawler crane complete machine performance to higher field, traditional principal arm arm head (tower head) complex structure, Heavy Weight, to the technological requirement height, both influenced the performance of car load, increased manufacturing cost again.
The utility model content
The technical problems to be solved in the utility model provides a kind of under the situation of other parameter constant of car load, have that load-carrying capacity is strong, simple for structure, weight is extremely light, reach the stability and the lifting performance that improve complete machine, low again to technological requirement simultaneously crawler crane principal arm arm head.
In order to solve the problems of the technologies described above, the crawler crane principal arm arm head that the utility model provides, whole arm head are welded by steel pipe by two groups of triangle high strength steel tubular constructions and constitute the main structure body; Lower plane at the main structure body utilizes steel pipe and presses the shape thin plate to form casing again, and described casing becomes the hanging point of hoisting pulley block; Described hoisting pulley block is supported by two groups of triangle pulling plate structures, two pin-and-holes are connected with the hanging point of arm head structure lower plane casing above the described triangle pulling plate structure, below one jiao of ground supports point as principal arm, middle connect by the main shaft that described hoisting pulley block is installed.
Adopt the crawler crane principal arm arm head of technique scheme, the transmission and the distribution graph of exerting oneself in different work operating mode and load according to principal arm arm head (tower head), reasonably design triangle main stress cross section structure form according to these figures, the transmission distance of shortening power, utilize high tensile steel tube as main frame structure cleverly, utilize the die mould thin plate to be combined into small box to improve local rigidity, structure has favorable manufacturability, has greatly alleviated the weight of principal arm arm head (tower head).Whole arm head is welded by steel pipe by two groups of triangle high strength steel tubular constructions, has constituted the main structure body; Utilize steel pipe and press the shape thin plate to form casing at lower plane again, be designed to the hanging point of hoisting pulley block; Hoisting pulley block is by two groups of triangle pulling plate structures, above two pin-and-holes be connected with the hanging point of arm head structure lower plane, below one jiao of ground supports point as principal arm, middlely connect by the main shaft that pulley is installed, can accomplish the aspect dismounting; Prevent the bearing of pour point again according to anti-dumping system reasonable Arrangement.
The utility model is compared with traditional principal arm arm head (tower head), has following characteristics:
1, under the situation of equal hoisting capacity, weight is extremely light, improves the stability and the lifting performance of car load greatly.
2, Du Te triangular-section tubular structure utilizes thin plate to strengthen mode, and is simple for structure, practical, makes simple.
3, satisfy several work operating mode function.Principal arm arm head of the present utility model (tower head) can also connect auxiliary arm head, fixedly auxiliary, tower luffing auxiliary and corresponding anti-dumping system, and main simultaneously lifting pulley group can be dismantled, and accomplishes a kind of structure multiple use fully.
In sum, the utility model is a kind of under the situation of other parameter constant of car load, has that load-carrying capacity is strong, simple for structure, weight is extremely light, reaches the stability and the lifting performance that improve complete machine, low again to technological requirement simultaneously crawler crane principal arm arm head.
