Abstract
The invention relates to a height adjusting plate. The height adjusting plate comprises a machine frame, a main panel, a lapping plate, a main panel jacking mechanism and a lapping-plate returning mechanism, wherein one side edge of the main panel is hinged to the machine frame, the other side edge of the main panel is hinged to the lapping plate, the main panel jacking mechanism is placed on the lower portion of the machine frame and is connected with the main panel in a jacking-up and transmission mode, and the lapping-plate returning mechanism is in elastic connection with the main panel and the lapping plate. According to the height adjusting plate, the main panel is jacked up by means of an airbag structure, the lapping plate is taken back through a pneumatic spring rather than a small-size hydraulic cylinder, and therefore oil dirt pollution caused by an existing hydraulic cylinder structure to work sites is prevented. Besides, jacking speed is high, and work efficiency is high.
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.The lifting body to main panel and attachment strap of present level regulating plate adopts hydraulic ram usually, and the problem that hydraulic ram exists greasy dirt to reveal in use inevitably makes that easily the loading and unloading place is contaminated, influences production safety.
Summary of the invention
The object of the invention is to address the above problem, and a kind of DOCK LEVELER that does not adopt hydraulic ram is provided, and is specifically realized by following technical scheme.
A kind of DOCK LEVELER, comprise frame, main panel, attachment strap, main panel lifting body and attachment strap response agency, described main panel one side and frame are hinged, its another side and described attachment strap are hinged, described main panel lifting body is in transmission connection as for frame lower and with described main panel jacking, and described attachment strap response agency elasticity connects main panel and described attachment strap.
Described DOCK LEVELER, its further design be that described main panel lifting body is air bag, this air bag bottom places that its top is connected with main panel and is connected with outside air pump on the frame.
Described DOCK LEVELER, it further designs and is that described air bag is that vinyl coarse fibre coated on both sides material is made.
Described DOCK LEVELER, it further designs and is that described attachment strap response agency is air bellow.
The present invention adopts airbag structure that main panel is carried out jacking, and by pneumatic spring but not the small-sized hydraulic oil cylinder reclaims the oil pollution of having avoided existing hydraulic ram structure to bring for the operation place, and jacking speed is fast, the operating efficiency height to attachment strap.
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, comprise frame 1, main panel 2, attachment strap 3, main panel lifting body and attachment strap response agency, main panel 2 one sides and frame 1 are hinged, and its another side and attachment strap 3 are hinged, and the main panel lifting body is in transmission connection as for frame lower and with the main panel jacking.Attachment strap response agency elasticity connects main panel and attachment strap.The attachment strap response agency is air bellow 5.
The main panel lifting body is air bag 4, and this air bag bottom places that its top is connected with main panel and is connected with outside air pump on the frame.Air bag is that vinyl coarse fibre coated on both sides material is made.This vinyl coarse fibre coated on both sides material is that the military ship of charging adopts material, and the intensity height can satisfy the operating needs in the jacking process.
In the operation process, after inflation is main panel lifting to air bag by outside air pump, lorry is moveed backward to the attachment strap below, thereby progressively venting makes the falling of main panel appropriateness that attachment strap is overlapped on the lorry to air bag, after operation finishes, make attachment strap leave lorry for again the inflation of air bag appropriateness, lorry is left, the air bag venting, meanwhile, attachment strap is replied under the deadweight effect, owing to adopted air bellow to avoid attachment strap that rigid collision takes place in Recovery Process.
The present invention adopts airbag structure that main panel is carried out jacking, the oil pollution of having avoided existing hydraulic ram structure to bring for the operation place, and jacking speed is fast, the operating efficiency height.
