Abstract
The utility model discloses a caterpillar crane track beam, chassis and caterpillar crane, caterpillar crane's unilateral is connected in parallel to weld or assemble through connecting device (3) by two track frame (1) and forms, constitutes parallel track beam (4), the utility model discloses it includes to disclose one kind simultaneously the chassis that parallel track beam constitutes reaches the caterpillar crane that the chassis constitutes. The utility model discloses can realize the interconnected system type of light -tonnage, well tonnage, large -tonnage four -wheel area, modularization batch production reduces to make the degree of difficulty, and reduction in production cost by a wide margin eliminates caterpillar crane's production bottleneck.
Description
Technical field
This utility model relates to a kind of crawler crane, specifically a kind of crawler crane track beam, and chassis and the described track beam of employing and the crawler crane on chassis.
Background technology
At present, domestic large-tonnage crawler crane improving constantly along with lifting tonnage, on chassis, four-wheel one band structure size is increasing, driving speed reducer model is increasing, manufacture difficulty of processing strengthens, and cost is the highest, it has also become the bottleneck of restriction crawler body development.
As depicted in figs. 1 and 2, crawler crane track beam of the prior art is side single-crawler single shelf structure, and it is relatively big that side uses single-crawler single frame to require the holding capacity of each track beam, thus the requirement of creeper tread and each wheel increases the most relatively.When improving product lifting capacity, track shoe width, bearing capacity etc. need to be increased accordingly, thus the system type causing size tonnage caterpiller crane can not reach four-wheel one band is produced in batches with modularity, increases manufacture difficulty, increase manufacturing cost, and then the cost that causes getting off is geometric increase.
Utility model content
The problem existed for above-mentioned prior art, this utility model provides a kind of safe and reliable, good economy performance, modular crawler crane track beam, chassis and crawler crane.
To achieve these goals, this crawler crane track beam crawler crane one side is welded by two frame track frame parallel connections, constitutes parallel track beam.
Further, crawler crane one side is assembled by attachment means parallel connection by two frame track frames, constitutes track beam.
Further, described attachment means uses bolt and connecting plate that two track frames carry out assembling in parallel.
This utility model provides a kind of chassis including described parallel track beam composition and the crawler crane of described chassis composition simultaneously.
Compared with prior art, this utility model can realize little tonnage, tonnage, the system type of large-tonnage four-wheel one band, and modularity is produced in batches, reduces manufacture difficulty, and production cost is greatly reduced, and eliminates the production bottleneck of crawler crane.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described further.
As it is shown on figure 3, this crawler crane track beam crawler crane one side is welded by two frame track frame 1 parallel connections, constitute parallel track beam 4.The upper cover plate of track frame 1 and lower shoe use two plate Type of Welding, it is possible to directly blanking is monolithic sheet material.The parallel track beam 4 of two set four-wheel one bands is assembled in track frame 1 welding after completing.
Further, as shown in Figure 4, crawler crane one side is assembled by attachment means 3 parallel connection by two frame track frames 1, constitutes track beam 4.Article two, track frame 1 links together by the way of attachment means 3 uses assembling, is formed and assembles parallel-connection structure, track frame 1 in parallel is installed two sets four-wheel one band in parallel altogether and constitutes parallel track beam 4.First two track beams 4 can also be assembled and carry out assembling in parallel by attachment means 3 again after four-wheel one carries.
Further, described attachment means 3 uses bolt and connecting plate that two track frames 1 carry out assembling in parallel, but is not limited only to bolt pattern, such as bearing pin connection etc..
As it is shown in figure 5, the present embodiment provides a kind of chassis including described parallel track beam composition and the crawler crane of described chassis composition simultaneously.
In sum, this utility model can realize little tonnage, tonnage, the system type of large-tonnage four-wheel one band, and modularity is produced in batches, reduces manufacture difficulty, and production cost is greatly reduced, and eliminates the production bottleneck of crawler crane.
