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, 8-head rod, 9-second connecting rod, 10-the 3rd connecting rod, 11-oscillating bearing, 12-frame, 13-supporting seat, 14-rubber pad, 15-the 4th connecting rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in detail:
This self-action 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.
Care the car when to carry out operation under the operating mode of pavement roughness, frame of caring the car often there will be torsional deformation, and motor is directly fixed on and frame of caring the car can causes engine shell body deformability thus damage; The utility model provides a kind of engine support for stationary engine, and engine support is fixed on is cared the car in frame by three application points (oscillating bearing connection).The deformation quantity avoiding frame torsional deformation of caring the car passes to motor body.Structure is simple, and reliability is high.
Below in conjunction with drawings and Examples, the utility model is described in detail, as shown in Figure 4:
This engine support comprises head rod, the second connecting rod and the 3rd connecting rod and the 4th connecting rod, wherein head rod is parallel with the 3rd connecting rod, second connecting rod is parallel with the 4th connecting rod, second connecting rod is vertical with head rod, second connecting rod two ends are connected with head rod and the 3rd connecting rod end winding support respectively, and head rod, the 3rd connecting rod are all vertical with frame of caring the car; Head rod, the second connecting rod and the 3rd connecting rod are combined with the 4th connecting rod, are built into the closed frame that has rational intensity and rigidity.
According to the installation dimension of motor, be equipped with four supporting seats in the upper planar cloth of engine support head rod and the 3rd connecting rod.
According to the structure of frame of caring the car, the lower plane of the head rod of engine support, the second connecting rod, the 3rd connecting rod is furnished with three interfaces.
Installation procedure:
1. motor is fixedly connected with by four lower margin buffer rubber gaskets and engine support four supporting seats.
2., by the motor that has been installed together and engine support, to be overallly fixedly connected with to three corresponding interfaces of frame of caring the car by three interface oscillating bearings of engine support;
The cost of above-mentioned engine support, shorten with causing engine life due to torsional deformation and compare with expenses such as corrective maintenances, its economic benefit is apparent.
