Abstract
The utility model relates to pitch and to care the car sliding door, comprise the slide rail being arranged on mixing hopper top side wall, slide rail extends to headstock direction, is provided with the support bar for supporting extension slide rail in the middle part of extension, support bar one end is fixedly connected with slide rail, and the other end is fixedly connected with car body; Slide rail is provided with can along the door-plate of slide rail movement.This pitch slide door structure of caring the car is simple, avoid existing above or the side mode of the opening the door problem of bringing highly increase and material to skid off; Meanwhile, because door-plate is all the time towards mixing hopper direction, door-plate is avoided to the full extent by outside impurity pollution thus to the problem causing pitch to pollute.
Description
Technical field
The utility model relates to pitch and to care the car sliding door, is mainly used in pitch and cares the car mixing hopper.
Background technology
Pitch sprinkling car is cared the car also known as pitch, and be a kind of dark-coloured pavement construction machinery, it is highway, urban road, the capital equipment that airport and port and pier are built.At employing pitch penetration method, when bitumen layer paving surface therapy builds flexible pavement or maintenance pitch or residual-oil pavement, pitch sprinkling car can be used to transport and (comprises hot pitch with spread liquid bitumen, mulseal and residual oil): it to the soil supply asphalt binder raveled on the spot, can also build asphalt soil stabilization road surface or sub-surface in addition.
Because pitch sprinkling car needs transport and spread liquid bitumen, and the temperature that liquid bitumen keeps certain should be made in transportation, therefore, pitch should be avoided in transportation to skid off from mixing hopper, current bituminous mixture case visit use hydraulic jack upward or side open the door, this structure not only causes the liquid bitumen of high temperature may be sliding from mixing hopper, and when also causing feeding, door height increases, impact charging or side members pollution bituminous mixture.
Summary of the invention
In order to solve Problems existing in background technology, the utility model provides pitch to care the car sliding door, and this slide door structure is simple, good sealing effect.
Concrete technical solution of the present utility model is as follows:
This pitch sliding door of caring the car comprises the slide rail being arranged on mixing hopper top side wall, slide rail extends to headstock direction, be provided with the support bar for supporting extension slide rail in the middle part of extension, support bar one end is fixedly connected with slide rail, and the other end is fixedly connected with car body; Described slide rail is provided with can along the door-plate of slide rail movement.
Described door-plate moves along slide rail and specifically door-plate both sides and slide rail cooperation place is provided with groove, and groove internal fixtion is provided with chain, and the length of chain is less than the length of groove; Described mixing hopper is provided with sprocket wheel on the sidewall of headstock, sprocket wheel and chain suitable.
The length of described chain is 4/5 ~ 9/10 of groove length, and chain is arranged in the middle part of groove.
Described sprocket wheel is driven by motor and rotates.
The utility model advantage is as follows:
This pitch slide door structure of caring the car is simple, avoid existing above or the side mode of the opening the door problem of bringing highly increase and material to skid off; Meanwhile, because door-plate is all the time towards mixing hopper direction, door-plate is avoided to the full extent by outside impurity pollution thus to the problem causing pitch to pollute.
Accompanying drawing explanation
Fig. 1 is the utility model door-plate closed condition structural representation;
Fig. 2 is the utility model door-plate open mode structural representation;
Fig. 3 is the partial enlarged drawing of the utility model chain and slide rail;
Accompanying drawing is detailed as follows: 1-support bar, 2-slide rail, 3-door-plate, 4-part chain and slide rail, 5-chain, 6-sprocket wheel, 7-motor.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
This pitch sliding door of caring the car comprises the slide rail being arranged on mixing hopper top side wall, because sliding door door-plate carries out opening and closing by slide rail, so the length of slide rail at least should ensure that the space that rear mixing hopper more than 2/3 opened by door-plate is exposed, so that operation; Therefore, slide rail needs to extend along the door-plate direction of motion; In order to avoid increasing length over ends of body, slide rail should be selected to extend to headstock direction.
Due to sliding door door-plate heavier mass, simple slide rail cannot support, and therefore needs the support component increasing slide rail; Can select bottom the slide rail extended and arrange at least one support bar between car body, the quantity of support bar and intensity should be relevant to the material of door-plate and weight.
Because sliding door door-plate needs to move along slide rail; therefore needing, corresponding slide unit is set mobile to ensure; a kind of relative movement mode is provided in the program, but is not limited to this move mode, anyly can make sliding door door-plate along the scheme of slide rail movement all at the row of this case protection.
Just above-mentioned move mode is specifically described below:
First, door-plate both sides are provided with groove, groove and slide rail suitable, to ensure that door-plate is relative airtight with mixing hopper under closed condition.
Secondly, door-plate moves along slide rail and adopts the mode of sprocket wheel and chain interoperation to carry out, at groove internal fixtion, chain is set, at mixing hopper, sprocket wheel is set on the sidewall of headstock, sprocket wheel engages with chain, sprocket wheel rotates and door-plate can be driven to move to sprocket wheel direction of rotation, and sprocket wheel drives by motor or other modes.
Again, in order to avoid sprocket wheel rotates excessively, door-plate is deviate from from compound box top, the length of chain should be controlled, or set up limiting component in the end of chain, advise the length setting of chain being 4/5 ~ 9/10 of groove length, and chain is arranged in the middle part of groove.
To sum up, the technical scheme that the utility model provides, structure is simple, effectively can solve problems of the prior art.
