Abstract
The utility model discloses a semitrailer ramp device, comprising a ramp on a frame, wherein a drive device for driving the ramp to swing on the frame is arranged on the frame, and is a hydraulic extension drive mechanism. The semitrailer ramp device can well ensure that the ramp can be accurately folded or released, the product has small failure rate to effectively ensure normal use of the ramp; and the ramp device can ensure that accurate folding or releasing of the ramp is easily realized only by the hydraulic extension drive device, and has simple structure, and the manufacture cost is greatly reduced compared with the traditional spring drive device.
Description
Technical field
The utility model relates to and a kind ofly is used to load goods from the trailer rear portion or from the springboard of trailer rear portion unloaded of cargo, is a kind of superimposed trailer access board apparatus specifically.
Background technology
At present, existing superimposed trailer product, the rear load or the unloading of trailer behind the product for convenience, generally all set up springboard in the vehicle frame rear end of superimposed trailer, particularly for weight big product or train product, by goods load or unload from the superimposed trailer itself, exempted utilization weight-lifting equipment (for example being fork truck or loop wheel machine) and carried out handling labor like this.Conventional superimposed trailer access board apparatus, it comprises the springboard 2 ' that is installed on the vehicle frame 1 ', is equipped with on the vehicle frame 1 ' to be used to drive the actuating device 3 ' that springboard 2 ' is moved on vehicle frame 1 ', actuating device 3 ' commonly used is actuating device of the spring, as shown in Figure 1.Actuating device of the spring generally is installed on vehicle frame 1 ' and the springboard 2 ' by bracing frame, and actuating device of the spring generally is provided with on bracing frame and connects a spring up and down.Yet in actual use, spring can occur certain fatigue through certain after flexible, makes that sometimes springboard 2 ' can not compact folding up, breaks down easily or the bottom surface of below completely, influences the normal use of springboard 2 '.In addition, actuating device of the spring needs with two springs about support and the setting, and its structure is comparatively complicated, has increased the manufacturing cost of product to a certain extent.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of fault rate superimposed trailer access board apparatus little, simple in structure and with low cost.
Goal of the invention of the present utility model is achieved in that a kind of superimposed trailer access board apparatus, it comprises the springboard that is installed on the vehicle frame, be equipped with on the vehicle frame and be used to drive the actuating device that springboard is swung on vehicle frame, it is characterized in that: described actuating device is the hydraulically extensible driver train.
For above-mentioned superimposed trailer access board apparatus, described hydraulically extensible driver train is a hydraulic ram.
In view of the further improvement of superimposed trailer access board apparatus described in the utility model, described hydraulic ram comprises cylinder body and piston rod, and piston rod inserts in the cylinder body from the front end of cylinder body.
Further, this superimposed trailer access board apparatus, the rear end of described cylinder body is hinged on the vehicle frame, and the front end of piston rod is hinged on the springboard.
And, superimposed trailer access board apparatus described in the utility model, described cylinder body is by being hinged on the vehicle frame with bearing.
The utility model is compared with superimposed trailer access board apparatus in the prior art, has the following advantages:
The utility model improves traditional superimposed trailer access board apparatus, the actuating device that will be used to drive the driving that springboard swings on vehicle frame changes and is made as the hydraulically extensible driver train, during this time, this hydraulically extensible driver train can be hydraulic ram, be not easy during the hydraulic pressure to break down, guarantee that well springboard can accurately fold or transfer, the fault rate of product is very little, has effectively guaranteed the normal use of springboard.And outer, this access board apparatus only needs a hydraulically extensible actuating device can realize accurately folding or transferring of springboard easily, and actuating device of the spring simple in structure, more traditional greatly reduces its manufacturing cost.
Description of drawings
Accompanying drawing 1 is the access board apparatus structural representation of existing superimposed trailer.
Accompanying drawing 2 is the structural representation of the described access board apparatus of the utility model most preferred embodiment, and the described springboard of this structure is positioned at collapse state.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
According to Fig. 2 and shown in Figure 3, superimposed trailer access board apparatus described in the utility model, it comprises the springboard 2 that is installed on the vehicle frame 1, springboard 2 is hinged on the vehicle frame 1, be equipped with on the vehicle frame 1 be used to drive the actuating device 3 that springboard 2 is swung on vehicle frame 1, this swing fulcrum is the hinge-point that springboard 2 is installed.The utility model improves at existing springboard 2 mechanisms, described actuating device 3 is changed be made as the hydraulically extensible driver train, and described hydraulically extensible driver train is a hydraulic ram, and hydraulic ram can have other device drives of superimposed trailer.Further improvement in view of superimposed trailer access board apparatus described in the utility model, described hydraulic ram comprises cylinder body 31 and piston rod 32, piston rod 32 inserts in the cylinder body 31 from the front end of cylinder body 31, further, the rear end of described cylinder body 31 is hinged on the vehicle frame 1, the front end of piston rod 32 is hinged on the springboard 2, and described cylinder body 31 is by being hinged on the vehicle frame 1 with bearing 4.
Access board apparatus shown in the accompanying drawing 3, it is to be in the state of transferring, the tail end ground proximity of springboard 2, goods or train product can be loaded on the superimposed trailer or directly are unloaded to ground from the superimposed trailer mountain by springboard 2 from springboard 2, and be convenient and simple.
So, superimposed trailer access board apparatus described in the utility model, it uses the hydraulically extensible driver train to replace common spring drive mechanism, owing to be not easy to break down during the hydraulic pressure, guarantee that well springboard 2 can accurately fold or transfer, the fault rate of product is very little, effectively guaranteed the normal use of springboard 2, and this access board apparatus only needs a hydraulically extensible actuating device 3 can realize accurately folding or transferring of springboard 2 easily, simple in structure, more traditional actuating device of the spring 3 greatly reduces its manufacturing cost.
