Abstract
The utility model discloses a synchronously steered hydraulic heavy over-limit transportation trailer, comprising a dynamic gooseneck, a bearing platform and a travelling mechanism, wherein a slewing bearing which is matched with a tractor saddle is arranged at the front part of the dynamic gooseneck; left and right gooseneck steering cylinders are respectively hinged on left and right sides of the slewing bearing; the travelling mechanism is formed by splicing a plurality of travelling units; the steering arms of the axle bodies of the travelling units on the same longitudinal beam are integrally hinged by a driving connecting rod; each driving connecting rod is connected with a travelling steering cylinder; the gooseneck steering cylinder and the travelling steering cylinder on the same side are arranged side by side; the front cavity of the gooseneck steering cylinder and the back cavity of the travelling steering cylinder on the same side are set to be oil inlet cavities; the oil inlet cavities are connected with an oil inlet pipe; and the steering directions of the dynamic gooseneck and the travelling wheel of the travelling mechanism are opposite. The synchronously steered hydraulic heavy over-limit transportation trailer is flexible and diverse in operations, the transportation tonnage of the whole trailer is increased, the turning radius can be reduced, the passage capacity of transportation vehicles is enhanced, convenience in driving is provided, and the safety of vehicles is improved.
Description
Technical field
The utility model relates to a kind of road transporting tool, particularly a kind of synchronous rotating to hydraulic heavy overload transport trailer.
Background technology
The common low-bed trailer of present domestic employing just can satisfy diameter below 4 meters, length is than the traffic requirements of the tank body kind equipments such as wind-power tower, boiler and chemical reactor of short weight amount below 50 ~ 60t.But along with the needs of development can constantly increase (reaching more than 5 meters even 5 meters) by these device diameters of common trailer transportation originally, weight is heavy (more than the 100t) more and more, length more and more reaches more than 30 meters, and the vehicle that is fit to this equipment of transportation just must be arranged.And require traffic cost relatively low.Also be not applicable to the transport trailer of ultralong overweight in the prior art.According to the GB1589-2004 regulation, the superimposed trailer vehicle commander limit value that transports non-dismountable object is not subjected to the restriction of national standard, so the superimposed trailer Vehicle length can be done length.The vehicle that length is grown is when the non-removable long materials of transportation, and turn radius is very large, is unfavorable for turn inside diameter, and in the situation of road injustice, easily causes and blow out, and also can affect the safety of driving simultaneously.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, proposed a kind of turning performance good, realize synchronous rotating to hydraulic heavy overload transport trailer.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of synchronous rotating to hydraulic heavy overload transport trailer, comprise the power gooseneck, hold loading platform and traveling gear, the front portion of power gooseneck is provided with the pivoting support that cooperates with the tractor truck saddle, the left and right sides of pivoting support is hinged with respectively left and right sides gooseneck steering cylinder, traveling gear is formed by several walking unit spliceds, described walking unit comprises left-right longeron, below left-right longeron, be provided with at least one group of vehicle bridge, two vehicle bridge bodies independently about every group of vehicle bridge comprises, fill the wheel that travels on the vehicle bridge body, the vehicle bridge body is contained on the longeron by adjustable hanging mechanism, the top of vehicle bridge body is provided with spindle arm, the spindle arm of the vehicle bridge body on the same longeron is articulated as one by drive link, front portion and/or afterbody at traveling gear are provided with the walking steering cylinder that is connected with above-mentioned drive link, be characterized in: the gooseneck steering cylinder of homonymy and walking steering cylinder are arranged in parallel, the ante-chamber of gooseneck steering cylinder is set to oil suction chamber with the back cavity of walking steering cylinder, oil suction chamber and oil inlet join, the opposite setting of steering direction of the wheel that travels of power gooseneck and traveling gear.
The technical problems to be solved in the utility model can also be come further to realize by the following technical programs, holds loading platform and comprises two side bars, is provided with some connecting cross beams between two side bars, is provided with the laterally end carriage of pull at the front end of two side bars.
The utility model provides the traveling gear of a kind of sliceable, drawing and pulling type, fluid-link steering, hydraulic heavy overload transport trailer.Can be according to the demand of the tonnage that transports tank body, can be with a bridge or plural many bridges component units body, one or more cell cubes are spliced, and the bridge number of the cell cube of splicing can be not identical, its flexible operation is various, can so that the transportation tonnage rank of car load get a promotion; The power gooseneck is opposite with the steering direction of the wheel that travels of traveling gear, can dwindle turn radius, has strengthened the performance of passing through of transport vehicle, makes driving more convenient, improves the safety of driving.
