Technical Field
The utility model belongs to the technical field of design and manufacture of transportation equipment, in particular to the technical field of design and manufacture of automotive semi-trailers, and particularly relates to an axle fixing device of a highway and railway dual-purpose semi-trailer.
Background Art
Semi-trailers usually employ an air suspension, which generally has an integral lifting function and is applied to an axle structure with a single axle or multiple axles. For a highway and railway dual-purpose semi-trailer, in order to adapt to both highway self-running and railway loading running, the air suspension thereof adopts a separable structure to adapt to different transportation modes; during railway loading running of the semi-trailer, it is required that axles and wheels are lifted to a certain height from a steel rail surface and cannot be lowered; and in general, wheel lifting is achieved through axle air suspension lifting, the axles need to be fixed during loading running after lifting, and after railway loading running, the axles are released and the axles and the wheels are lowered to restore the highway self-running.
Summary of the Utility Model
The utility model discloses an axle fixing device of a highway and railway dual-purpose semi-trailer according to the defects of the prior art. The problem to be solved by the utility model is to provide a semi-trailer axle and a suspension system thereof, wherein the semi-trailer axle allows axles to be fixed and released so as to adapt to both highway self-running and railway loading running.
The utility model is realized by the following technical scheme:
According to an axle fixing device of a highway and railway dual-purpose semi-trailer, the highway and railway dual-purpose semi-trailer is of a single-axle or multi-axle structure, each axle structure comprises an independent axle, a frame and an air suspension for connecting and lifting the axle and the frame, and the axle fixing device is characterized in that:
each independent axle is fixedly provided with a hanging plate perpendicular to the axle, and a hanging pin parallel to an axial direction of the axle is arranged at an upper end part of the hanging plate;
l
2019100333 01 Apr 2019 and corresponding to the positions of the hanging plate and the hanging pin of each axle, a hook seat plate is fixedly arranged on a bottom surface of the corresponding frame, a rotatable hook is arranged on the hook seat plate, and the hook is locked and fixed with the hanging pin after the axle is lifted.
Each hook is locked and fixed with the corresponding hanging pin after being driven by a cylinder to rotate to allow the corresponding axle to be lifted, and the cylinder is matched with an air bag of the corresponding air suspension for connecting and lifting the axle.
A middle part of each hook is hinged with a cylinder piston through a hinge shaft to realize rotation driven by the cylinder.
The hook and the hanging pin of each axle are driven by a same air source and synchronously locked and released.
When the axle fixing device of the highway and railway dual-purpose semi-trailer runs on a semi-trailer road, the hooks and the hanging pins are in a free state, and the hooks are fixed by the cylinder pistons. When railway loading running is required, the air suspensions are started and the cylinders run matched therewith through self-running of the semi-trailer or by hoisting the semi-trailer on a railway sweep, the axles are lifted by the air suspensions to increase the distance between the wheels and the ground, and meanwhile, the cylinders drive the hooks to rotate so as to be locked and fixed with the hanging pins; and after railway loading running, the air suspensions and the cylinders are reversely operated to release the axles, thus realizing running mode switch. The utility model has the beneficial effects that the fixing device is arranged according to the axle structure, the axles are locked and released synchronously, the hooks can be driven to be fixed and driven to rotate, and the fixing device is safe, reliable and stable under different operating modes. The whole mechanism is simple in structure, good in manufacturing and assembling processability and high in reliability; stability and safety are high during operation; a gas circuit system is simple in structure, quick to assemble and simple and reliable in operation performance; a pressure in the cylinders and a pipeline and a valve body of the whole air circuit system is small, so the reliability of the whole system is improved; and the vehicle can run more safely and stably by means of a mechanical locking manner.

Detailed Description of the Utility Model
The utility model will now be further described with reference to specific embodiments, which are further illustrative of the principles of the utility model and are not intended to limit the utility model in any way, and the same or similar techniques may be used without departing from the scope of the utility model.
According to the drawings, an axle fixing device of a highway and railway dual-purpose semi-trailer is suitable for a single-axle or multi-axle structure of the highway and railway dual-purpose semi-trailer, wherein each axle structure comprises an independent axle, a frame and an air suspension for connecting and lifting the axle and the frame.
Each independent axle is fixedly provided with a hanging plate 1 perpendicular to the axle, and a hanging pin 2 parallel to an axial direction of the axle is arranged at an upper end part of the hanging plate 1;
and corresponding to the positions of the hanging plate 1 and the hanging pin 2 of each axle, a hook seat plate 3 is fixedly arranged on a bottom surface of the corresponding frame, a rotatable hook 5 is arranged on the hook seat plate, and the hook 5 is locked and fixed with the hanging pin 2 after the axle is lifted.
Each hook 5 is driven by a cylinder 4 to rotate to be locked and fixed with the corresponding hanging pin 2 after the corresponding axle is lifted, and the cylinder 4 is matched with an air bag of the corresponding air suspension for connecting and lifting the axle.
A middle part of each hook 5 is hinged with a cylinder 4 piston through a hinge shaft to realize rotation driven by the cylinder 4.
The hook 5 and the hanging pin 2 of each axle are driven by a same air source and synchronously locked and released.
As shown in the drawings, Fig. 1 is a structural diagram of an axle according to the present utility model in a free state, in which the hook 5 and the hanging pin 2 are in a free state, and the hook 5 is fixed by the cylinder 4 piston. Fig. 2 is a structural diagram of an axle according to the present utility model in a fixed state, in which the air suspension lifts the axle to increase the distance between the wheel and the ground, and meanwhile, the cylinder 4 drives the hook 5 to rotate so as to be locked and fixed with the hanging pin 2.
The axle fixed process is that the cylinder 4 is in an air-off state, the hook 5 is in a vertical state, the air bag is lifted for air introduction, the axle is lifted through a lifting lever, and the hanging pin 2 touches the hook 5 and is locked in the lifting process.
The axle released process is that the air bag is lifted for air introduction firstly, after the axle is lifted to a certain height through the lifting lever, the cylinder 4 pushes the hook 5 away from the
2019100333 01 Apr 2019 hanging pin 2 after air introduction, then the air bag is lifted for air release, and the axle descends, thus realizing the release of the axle.
