Abstract
The invention provides an anti-collision protecting device for a box door. The anti-collision protecting device for the box door is characterized by comprising a difunctional hydraulic cylindrical shock absorber (1), a lower box door buffering bracket (2), the front segment of an upper box door buffering bracket (3), the rear segment of the upper box door buffering bracket (4) and connecting and fixing screws. According to the anti-collision protecting device, the characteristic that the difunctional hydraulic cylindrical shock absorber (1) is small in damping force when compressed and is large in damping force when stretched is utilized, and the segmental design of the front segment of the upper box door buffering bracket and the rear segment of the upper box door buffering bracket is combined; in this way, the box door is prevented from impacting a box door frame, a leakage caused by damage to sealing rubber strips is avoided, a leakage caused by deformation of the box door is avoided, the service life of the box door and the service life of sealing elements are prolonged, and sealing performance is improved.
Description
Technical field
The present invention relates to a kind of chamber door anti-collision protection device of mobile garbage compressor station.
Background technology
At present, the existing mobile garbage compressor station in the whole world does not have chamber door buffer, because chamber door knocking door case or casing cause sealing joint strip damage, chamber door or doorframe distortion, cause that chamber door sealing function loses, when filling rubbish and transport, sewage in case trickles everywhere, causes serious environment pollution.Therefore, sealing joint strip needs frequent replacing, chamber door to need frequent maintenance, causes working service with high costs.
Summary of the invention
The object of this invention is to provide a kind of chamber door anti-collision protection device, from following 2 principles, solved this defect: buffer need to meet the without hindrance normal unlatching of chamber door; Buffer applies damping force to chamber door when chamber door is closed makes chamber door move to guarantee that with controlled speed door and doorframe can not clash into.
In order to achieve the above object, the invention provides following technical scheme:
A chamber door anti-collision protection device, is characterized in that it comprises: double-action hydraulic telescopic shock absorber, chamber door buffering lower carriage, chamber door buffering upper bracket leading portion, chamber door buffering upper bracket back segment, connection and fixed screw.In invention, the very large characteristic of damping force during little, the Tensile of damping force owing to utilizing double-action hydraulic telescopic shock absorber by compression, engages segment design before and after damper upper bracket; Therefore, avoid the shock of chamber door to door frame of box, avoid sealing joint strip to damage and cause seepage, avoid chamber door distortion to cause seepage, extend chamber door and seal durability, improve sealing usefulness.
The invention has the beneficial effects as follows: avoid the shock of chamber door to door frame of box, avoid sealing joint strip to damage and cause seepage, avoid chamber door distortion to cause seepage, extend chamber door and seal durability, improve sealing usefulness, can bring good economic benefit, energy conservation, minimizing are polluted.
Accompanying drawing explanation
Fig. 1 is the structural representation of chamber door anti-collision protection device.
Fig. 2 is the structural representation under chamber door opening of the present invention.
Fig. 3 gets back to the structural representation of doorframe under chamber door opening of the present invention.。
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further elaborated.
As Fig. 1 and as shown in, a kind of chamber door anti-collision protection device, is characterized in that it comprises: double-action hydraulic telescopic shock absorber 1, chamber door buffering lower carriage 2, chamber door buffering upper bracket leading portion 3, chamber door buffering upper bracket back segment 4, connection and fixed screw.In invention, the very large characteristic of damping force during little, the Tensile of damping force owing to utilizing double-action hydraulic telescopic shock absorber 1 by compression, in conjunction with 4 designs of segmentation before and after damper upper bracket; Therefore, avoid the shock of chamber door to door frame of box, avoid sealing joint strip to damage and cause seepage, avoid chamber door distortion to cause seepage, extend chamber door and seal durability, improve sealing usefulness.
As shown in Figure 2, when garbage truck is dumped rubbish, open smoothly at the structure on damper upper bracket two-piece type band inclined-plane assurance back door, and guarantee when maximum is reached at back door also can not damage hydraulic pressure cylinder type damper.
As shown in Figure 3, when vehicle is finished down after rubbish to overtake, chamber door can be beaten to doorframe because of Action of Gravity Field, when shock absorber upper bracket inclined-plane closure, hydraulic pressure cylinder type damper 1 produces the rapid movement that damping force stops door, thereby eliminate the collision of door and doorframe, this damping power be take and guaranteed that door and doorframe do not produce that to collide be standard.
The operating principle of above-mentioned chamber door anti-collision protection device is: double acting telescopic shock absorber by compression time damping force very I to meet the needs that open the door smoothly; During double acting telescopic shock absorber Tensile, damping force can meet very greatly and makes chamber door with controlled speed motion requirement; Chamber door buffering lower carriage plays fixedly damper and bears the effect of damper slide force; Chamber door buffering lower carriage have certain length rise by damper mounting points move to door hinge away from chamber door one side, can reduce required damping force, thereby reduce damper size and cost; Chamber door buffering upper bracket back segment plays fixedly leading portion and bears the effect of damper slide force; Chamber door buffering upper bracket back segment coordinates with leading portion by inclined-plane, guarantees as damper has been retracted to minimum length, can not damage damper when chamber door is opened; Chamber door buffering upper bracket back segment coordinates with leading portion by inclined-plane, and while guaranteeing that chamber door is closed, damper produces the quick closedown of damping force prevention chamber door; Chamber door buffering upper bracket leading portion plays fixedly damper and bears the effect of damper slide force; Chamber door buffering upper bracket leading portion coordinates with back segment by inclined-plane, guarantees as damper has been retracted to minimum length, can not damage damper when chamber door is opened; Chamber door buffering upper bracket leading portion coordinates with back segment by inclined-plane, and while guaranteeing that chamber door is closed, damper produces the quick closedown of damping force prevention chamber door.
According to above-mentioned operating principle: owing to having adopted while utilizing double-action hydraulic telescopic shock absorber by compression, damping force is little, the very large characteristic of damping force during Tensile, engage damper upper bracket front and back segment design, when before and after upper bracket, section utilizes inclined-plane to coordinate realization to unpack door, support is turning, avoid damaging damper, and make damping force of vibration damper at closing time obtain effectively utilization.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present invention and technical scheme to carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasions, all within protection scope of the present invention.
