Description

Technical Field

[0001] The present application relates to the technical field of temporary road paving, and in particular to a repairable hard motor vehicle front paving device and a repair method. Background Art

[0002] Hard mobile pavement can be laid in areas with limited ground bearing capacity, i.e. swamps, sandy land or roads that may be damaged by continuous traffic, to provide passage for heavy equipment, tanks and other vehicles. At present, hard mobile pavement is also widely used in beach landing, island landing, disaster relief and other fields. It not only provides obstacle crossing support when the Marine Corps seizes key points on the beach, but also ensures that subsequent tanks, artillery and other heavy equipment can overcome the soft and muddy beaches on the waterside beach when landing; it can also play an important role in the emergency rescue process of road damage.

[0003] At present, the only hard mobile pavement laying methods on the market are rear laying and rear withdrawal. However, in the actual process of disaster relief or beach landing, the rear laying operation method cannot meet the needs of the actual working environment. Therefore, on the basis of the rear laying operation method, a front laying device is added to perform the front laying operation of the road surface, which improves the practicality of the hard mobile pavement vehicle. Since the front laying device and the operation process need to cross the entire chassis cab, and the important parts on the chassis are all at the bottom of the cab, considering the maintainability of the chassis, it is urgent to design a maintainable front laying hard mobile pavement vehicle to meet the emergency market and military needs. Summary of the invention

[0004] In view of this, the present invention provides a maintainable front paving device for hard motorized pavement. The equipment is composed of a front support assembly, a front support rod, an upper guide frame assembly, a manual oil cylinder, a bracket assembly, etc. It ensures that the pavement can be paved in front and the equipment is maintainable.

[0005] The present invention is achieved through the following technical solutions:

[0006] A repairable hard motor vehicle front paving device comprises a front support assembly, a front support rod, an upper guide frame assembly, a bracket assembly, a guide rod, etc.;

[0007] The front support assembly is installed at the front bumper of the chassis vehicle, and is mainly composed of an upper guide roller assembly, a chassis front fender support, a lower guide roller assembly, a front fender buckle, etc. The upper guide roller assembly is modified from the chassis bumper front fender, and includes a front bracket assembly, a chassis front fender support, a front fender buckle, a guide wheel, a roller, a bolt, a cotter pin, etc.

[0008] The front guard frame of the chassis vehicle is removed, and the front guard frame support is retained on the chassis vehicle. The front bracket assembly is installed on the front bumper of the original vehicle, and is fixed to the front guard frame support through a pin shaft and a cotter pin using the existing front guard frame support and front guard frame buckle on the original vehicle. When the chassis vehicle needs to be repaired, the front guard frame buckle is unfastened, and the upper guide roller assembly is flipped down around the pin shaft until it does not block the front cover of the chassis vehicle cab. The front cover of the cab is opened for preliminary inspection and repair. The upper guide roller assembly is fixed by a pin shaft and a cotter pin, and the cotter pin and the pin shaft can also be removed, and the buckle is unfastened, and the entire upper guide roller assembly is separated from the entire front laying device structure, which does not affect the maintenance of the chassis vehicle.

[0009] The existing front fender support on the original vehicle is connected to the chassis vehicle beam, and the strength of this part can ensure sufficient strength and rigidity stability; the front fender buckle can also increase the stability and strength of the entire upper guide roller assembly during system operation.

[0010] Guide wheels and rollers are respectively installed at both ends of the front support assembly for supporting and guiding the road surface during the front paving process.

[0011] The lower guide roller assembly is composed of a lower roller support, a guide wheel, a roller, a roller shaft, a bushing, bolts, etc., and is installed at the lower part of the chassis bumper. This structure can guide the road surface to the bottom of the front wheel of the chassis along the rut track without affecting the maintenance of the chassis.

[0012] The two ends of the front support rod are movable ear plates, the lower ear plate is connected to the upper ears of the front support assembly through a pin shaft and a split pin, and the upper ear plate is connected to the front ears of the upper guide frame assembly through a pin shaft and a split pin to support the entire structure. If necessary, the split pin and the pin shaft can be removed to separate the front support rod from the front laying structure.

[0013] The upper guide frame assembly is installed on the upper part of the chassis cab, spans over the chassis cab and transitions to the front end of the chassis to connect with the front support assembly. The rear end of the upper guide frame assembly is connected to the ball head of the bracket assembly. This connection method can be quickly separated from the bracket assembly without manual assistance. The upper guide frame assembly is provided with a cylinder support.

[0014] The lower end of the bracket assembly is fixedly mounted on the chassis vehicle sub-beam, the ball seat at the upper left end is connected to the middle ball head of the upper guide frame assembly, and the upper right end is connected and fixed to the rear end support ear of the upper guide frame assembly. A cylinder support is arranged on the bracket assembly, and the manual cylinder is respectively mounted on the cylinder support of the upper guide frame assembly and the cylinder support of the bracket assembly.

[0015] When the chassis is repaired, the upper guide frame assembly is lifted up by a manual oil cylinder, the ball head of the upper guide frame assembly is separated from the ball seat of the bracket assembly, and the chassis is turned around a pivot point of the vehicle head to carry out maintenance operations. The oil cylinder stroke can ensure that the chassis will not interfere with the lifted upper guide frame assembly when turning over.

[0016] The beneficial effects of the present invention are as follows: (1) the upper guide roller assembly is modified by the front guard frame of the chassis bumper, and the front guard frame support of the chassis can be used to ensure the strength of the front paving structure. The upper guide roller assembly can be flipped downward to ensure that the chassis can be repaired without blocking the chassis front cover and the chassis front from flipping; (2) the front support rod is movable, and is connected to the front support assembly and the upper guide frame assembly respectively through a pin shaft and a cotter pin. During the front paving operation, the entire structure is integrated. When the chassis vehicle needs maintenance, the front support rod can be removed to facilitate maintenance of the chassis vehicle; (3) A manual cylinder is arranged between the upper guide frame assembly and the bracket assembly. When the chassis vehicle needs maintenance, the upper guide frame can be directly lifted up a certain distance by the manual cylinder, and the front of the chassis vehicle can be flipped around the fulcrum for maintenance; (4) The upper guide frame assembly and the bracket assembly are connected by a ball head and a ball seat. When the manual cylinder is lifted, the two parts can be quickly separated, and no operator assistance is required. The operation is convenient and time-saving; (5) It not only ensures that the road surface can be laid in advance, but also that the chassis vehicle can be repaired at any time when a chassis vehicle fails, thus ensuring the functionality and maintainability of the hard motorized road surface.
