Abstract

A lifting and steering device for a front frame of a molten iron tank transportation vehicle. The lifting and steering device mainly comprises an axle traction beam (1) and a traction fixing base (2) disposed on a front frame. An upper swing arm (3) and a lower swing arm (4) are respectively hingedly connected to the top portion and the bottom portion of the traction fixing base (2). A steering arm (5) is hingedly connected to the other end of each of the upper swing arm (3) and the lower swing arm (4). A loading oil tank (6) is disposed between the upper swing arm (3) and the traction fixing base (2). A hingedly-connected connection plate (7) fixedly connected to a rear frame of the vehicle is hingedly connected to the steering arm (5). The lifting and steering device also comprises a front steering oil tank (9). The front steering oil tank (9) is mounted on the rear frame of the vehicle. A piston rod end of the front steering oil tank (9) is hingedly connected to support lugs (8) on two sides of the steering arm (5). In the lifting and steering device for a front frame of a molten iron tank transportation vehicle, a lifting and steering mode combining mechanical compression and hydraulic compression is used, the operations are simple, and the maintenance is easy, thereby greatly reducing production costs.

Description

Description: The name of the invention: the front frame lifting steering device of the molten iron tank truck

[0001] The utility model relates to a heavy-duty transport vehicle, in particular to a lifting and steering device for a front frame of an internal combustion fixed platform molten iron tank truck used for transporting high-temperature iron water tanks in a steel factory. It belongs to the field of special equipment technology. Background technique

[0002] In the fields of bridges, machinery, shipbuilding, metallurgy, etc., shipyard hull transport, short-distance transport of prefabricated bridges for highway construction, steel mill baskets, ladle, steel slabs, finished products, etc., special vehicles required for load capacity, There are specific requirements in terms of driving, flexibility, and reliability.

[0003] At present, the truck used for steel plant transportation of high-temperature iron water tank adopts hydraulic independent suspension multi-axis bearing, hydrostatic driving, all-wheel steering and other technologies. The hydraulic body is independently suspended to realize the lifting and lowering of the vehicle body. The power system adopts hydrostatic driving technology. The whole frame of the vehicle adopts a monolithic structure and adopts an all-wheel steering system. Due to the limitation of the structure of the vehicle itself, the connecting rod structure cannot be connected. The two groups of steering structures are synchronously steered, resulting in a large turning radius of the whole vehicle, which is limited by the site. The lifting, leveling, vehicle damping and driving support functions of the whole vehicle are realized by the hydraulic system, which makes the design and processing of the vehicle. The cost is increased, and the hydraulic system is easy to be damaged and wrong in actual use, and the maintenance is troublesome, which affects the normal use efficiency. technical problem

[0004] The technical problem to be solved by the utility model is to provide a lifting and steering device for the front frame of the molten iron tank truck for the above prior art, which adopts a mechanical and hydraulic matching lifting and lowering mode, which is simple and easy to maintain, and greatly reduces the production. cost.

Problem solution

Technical solution

[0005] The technical solution adopted by the utility model to solve the above problems is as follows: A front-frame lifting and steering device for a molten iron tank truck, mainly comprising an axle traction beam and a traction fixing seat fixed on the front frame, An upper swing arm and a lower swing arm are respectively coupled to the top and the bottom of the traction mount, and a steering arm is hinged on the other end of the upper swing arm and the lower swing arm, and a loading is arranged between the upper swing arm and the traction mount a hydraulic cylinder, on the steering arm, a hinged connecting plate fixedly connected with the rear frame, and a front steering cylinder The front steering cylinder is mounted on the rear frame, and the piston rod end is hinged with the connecting lugs on both sides of the steering arm, and the front steering cylinder generates a thrust force on the connecting lug, and the thrust acts on the four-link lifting mechanism. Acting on the drive wheel to achieve front frame steering.

Advantageous effects of the invention

Beneficial effect

[0006] In the utility model, a power lifting steering system is installed on the front frame, and the driving is realized by a mechanical mechanism to drive the rear car to turn and advance, instead of the complicated hydrostatic driving mode, the hydraulic and control system is greatly simplified, and the hydraulic system is greatly reduced. System failure, effectively reducing maintenance costs.

BEST MODE FOR CARRYING OUT THE INVENTION

[0010] The present invention will be further described in detail below with reference to the embodiments of the drawings.

[0011] The utility model relates to a front and rear frame lifting and steering device for a molten iron tank truck, which mainly comprises an axle traction beam ₁ fixedly mounted on the front frame and a traction fixing seat ₂ mounted on the axle traction beam ₁ . An upper swing arm 3 and a lower swing arm 4 are respectively hinged at the top and the bottom of the traction mount 2, and a steering arm 5 is hinged at the other end of the upper swing arm 3 and the lower swing arm 4, and the traction mount 2 is hinged The upper swing arm 3, the lower swing arm 4 and the steering arm 5 form a four-bar linkage mechanism. A loading cylinder 6 is disposed between the upper swing arm 3 and the traction mount 2, and the cylinder portion of the loading cylinder 6 is fixed to On the upper swing arm 3, the piston rod portion is connected to the traction fixed seat 2, and the hinged connecting plate 7 fixedly connected with the rear frame is hinged on the steering arm 5, thereby realizing the split type of the front frame and the rear frame. Hinged; a connecting lug 8 is provided on both sides of the steering arm 5, and the connecting lug 8 is hinged to the front steering cylinder 9 mounted on the rear frame, and the connecting lug 8 is generated by the front steering cylinder 9 Thrust, which acts on the four-link lifting mechanism and ultimately acts on the drive Wheel, thereby achieving the steering of the front frame.
