Abstract
The invention relates to a height adjusting plate which comprises a rack, a main panel, a lapping plate, a main panel jacking mechanism, a supporting leg and a lapping plate return mechanism, wherein one side edge of the main panel is articulated with the rack; the other side edge of the main panel is articulated with the lapping plate; the main panel jacking mechanism is placed at the lower part of the rack, and connected with the main panel in a jacking transmission manner; the lapping plate return mechanism is elastically connected with the main panel and the lapping plate; the supporting leg is articulated with the lower part of the main panel; a flexible plate is fixedly arranged on the lower side surface of the lapping plate; the outer end part of the flexible plate is contacted and connected with the supporting leg; and the flexible plate jacks the supporting leg to a horizontal state when the lapping plate rotates to a horizontal position. According to the height adjusting plate, the main panel is jacked by an air bag structure, so that oil pollution brought to an operating site by the existing hydraulic oil cylinder structure is avoided; the jacking speed and the operating efficiency are high; rigid impact easily generated in a return process of the lapping plate is avoided by an air spring; and the supporting leg can be folded automatically by a flexible plate structure.
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, the main panel lifting body, feet 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 places frame lower and is in transmission connection with described main panel jacking, described attachment strap response agency elasticity connects main panel and described attachment strap, described feet is articulated in the main panel bottom, described attachment strap downside is set with one and scratches plate, this outer end of scratching plate is connected with described feet contact, when attachment strap turns to level attitude, scratch plate support foot is pushed up to horizontality.
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, 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; Avoided the easy rigid collision that produces in the attachment strap Recovery Process by air bellow; Make feet to draw in automatically by scratching plate structure.
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, feet 6 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 places frame lower and is in transmission connection 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.Feet 6 is articulated in the main panel bottom, and the attachment strap downside is set with one and scratches plate 31, and this outer end of scratching plate 31 is connected with the feet contact, when attachment strap turns to level attitude, scratches plate support foot is pushed up to horizontality.
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, at this moment, attachment strap and main panel are in straightened condition, and support foot is in horizontality under the effect of scratching plate, 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, after attachment strap was replied vertical state, feet was in vertical state main panel is carried out supporting role under the deadweight effect.
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; Avoided the easy rigid collision that produces in the attachment strap Recovery Process by air bellow; Make feet to draw in automatically by scratching plate structure.
