Abstract
The utility model discloses a circular centering positioning device of caterpillar crane arm support. The device includes a positioning plate. One side of a first positioning plate is fixedly connected with a first assembly part and the other side of the first positioning plate is circular. A second positioning plate is round. The circular arc of the first positioning plate is jointed with the external circle of the second positioning plate. The second positioning plate is fixedly connected with a second assembly part through a bolt. The center of the second positioning plate is provided with an axle hole. And a pin roll is arranged in the axle hole. The utility model solves the problem that a truss type arm support of caterpillar crane is hard to be mounted and positioned and realizes accurate positioning through the centering of the circular arc of the positioning plate. The utility model can prevent the parts from damage caused by impact and can automatically centralize to reach the mounting position with no man power to move the parts. The utility model has the advantages of simple structure, low cost, no need of external power, practicality and reliability, convenient mounting and transportation as well as easy popularization. The utility model can be used for the mounting and positioning of a caterpillar crane arm support.
Description
Technical field
The utility model relates to a kind of crawler crane boom mounting and positioning device.
Background technology
At present, the installation of crawler crane truss-like jib adopts auxiliary hoist lifting and this machine from the dismounting dual mode more.In the process of slinging, can occur inevitably that parts wave or center of gravity does not have the situation of centering.And big because of the parts volume in trimming process, quality heavily waits reason to be difficult to finish correction by manpower, and assembling is difficulty very, even cause the collision of parts, damages.Not only waste the manpower financial capacity, restricted the safety of working process, and increased working time, reduced work efficiency.
Summary of the invention
The purpose of this utility model is that a kind of crawler crane boom circular arc centering registration device will be provided, and this device guarantees that crawler crane jib installation correction in the transition process is convenient, and saves time, and is laborsaving.
The purpose of this utility model is achieved in that this device comprises locating plate, first locating plate is captiveed joint with first assembly parts on one side, the first locating plate another side is a circular arc, second locating plate is circular, the cylindrical of the circular arc of first locating plate and second locating plate fits, second locating plate is captiveed joint with second assembly parts by bolt, and the second locating plate center is provided with axis hole, and bearing pin is positioned at axis hole.
Advantage of the present utility model: (1) has solved the problem of crawler crane truss-like jib installing and locating difficulty, realizes accurate in locating by the centering of locating plate circular arc.(2) can prevent that parts from because of the damage that collision produces, do not need the manpower moving-member, thereby automatic centering reaching the installation site.(3) simple in structure, cost is low, does not need external power.(4) practical reliable, simple installation is convenient to transportation, is easy to promote.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
1. bearing pins among the figure, 2. second locating plate, 3. first locating plate, 4. first assembly parts, 5. second assembly parts, 6. bolt.
The specific embodiment
In Fig. 1, captive joint with first assembly parts 4 in first locating plate, 3 tops, and first locating plate, 3 bottoms are circular arc.Second locating plate 2 is circular, and the cylindrical of the circular arc of first locating plate 3 and second locating plate 2 fits.Second locating plate 2 is captiveed joint with second assembly parts 5 by bolt 6, and second locating plate, 2 centers are provided with axis hole, and bearing pin 1 is positioned at axis hole.
First locating plate 3 is welded on to be needed on stack-mounted jib first assembly parts 4, and guarantees to ream with one heart being connected of first locating plate 3 and first assembly parts 4 by machinework.
Second locating plate 2 is fastened on second assembly parts 5 by bolt 6, guarantees that second locating plate 2 is concentric with the fraising of second assembly parts 5.
The endoporus of second locating plate 2 and cylindrical guarantee with one heart by machinework.
The arc diameter that guarantees first locating plate 3 by machinework is identical with the arc diameter of second locating plate 2, thereby guarantees that they are concentric after fitting.
During installation, first locating plate 3 is stuck in self-orientation on second locating plate 2, and the centering center of circle guarantees that the hinge of first assembly parts 4 and second assembly parts 5 is concentric.After two circular arcs of first locating plate 3 and second locating plate 2 are sturdy fully, just bearing pin 1 easily can be advanced in the connecting bore, finish installation.
