Abstract
The invention relates to a plate with the adjustable height. The plate comprises a machine frame, a main panel, an overlapping plate and a recovering mechanism. One side edge of the main panel is hinged to the machine frame, and the other side edge of the main panel is hinged to the overlapping plate through the recovering mechanism. The recovering mechanism is connected with the lower side face of the main panel and the lower side face of the overlapping plate. A pneumatic spring is adopted for preventing the overlapping plate from colliding with the main panel rigidly when the overlapping plate is recovered, a hydraulic oil cylinder is used less correspondingly, and therefore the plate is environment-friendly.
Description
Technical field
The present invention relates to a kind of DOCK LEVELER.
Background technology
DOCK LEVELER is to realize the goods special-purpose logistics equipment of loading and unloading fast, has the height regulatory function, can between the goods platform of lorry and storehouse, erect a bridge block, make things convenient for handling carrier such as fork truck to carry out loading and unloading operation by stepping on the vehicle bridge lorry of coming in and going out, only need a people, can finish loading and unloading operation safely and fast.During the DOCK LEVELER operation, attachment strap is horizontality, and after operation was finished, attachment strap was vertical state, the variation of common above-mentioned state is finished by the small-sized hydraulic oil cylinder that is located on the main panel, and the use of hydraulic ram produces the greasy dirt leakage inevitably to the pollution in operation place.
Summary of the invention
The object of the invention is to address the above problem, thereby a kind of DOCK LEVELER that adopts open bindiny mechanism to improve connecting bridge intensity is provided, and is specifically realized by following technical scheme.
A kind of DOCK LEVELER comprises frame, main panel, attachment strap and recovering mechanism, and described main panel one side and frame are hinged, and its another side is hinged by described and described attachment strap, and described recovering mechanism connects the downside of described main panel and attachment strap.
Described DOCK LEVELER, it further designs and is that described recovering mechanism is elastic bar.
Described DOCK LEVELER, it further designs and is that described elastic bar is air bellow.
When having adopted pneumatic spring to reclaim to avoid attachment strap, the present invention with main panel generation rigid collision, reduced the use of corresponding hydraulic ram, comparatively environmental protection.
Description of drawings
Fig. 1 is structural representation of the present invention.
The specific embodiment
The present invention will be described below in conjunction with Figure of description and specific embodiment.
This DOCK LEVELER comprises frame (not drawing among the figure), main panel 1, attachment strap 2 and recovering mechanism 3, and main panel one side and frame are hinged, and its another side is by hinged with attachment strap, and recovering mechanism connects the downside of main panel and attachment strap.Elastic bar is air bellow.
Because for adopting the small-sized hydraulic oil cylinder, when operation, to the higher position, lorry is poured the main panel jacking into the attachment strap below earlier, thereby retelling main panel decline certain altitude makes attachment strap and lorry overlap joint be in horizontality, behind the end-of-job, attachment strap falls after rise naturally, and this moment, air bellow made that the falling process of attachment strap is comparatively gentle, had avoided the rigid collision of itself and corresponding mechanism.
When having adopted pneumatic spring to reclaim to avoid attachment strap, the present invention with main panel generation rigid collision, reduced the use of corresponding hydraulic ram, comparatively environmental protection.
Claims (3)
