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.
When carrying out flexible pavement laying or repairing work, should ensure as far as possible to meet job requirements for the asphalt temperature of operation and temperature is relatively uniform; This practicality is carried out based on this requirement, emulates existing bituminous mixture case internal temperature, finds that V-type preventing materials accumulation plate top asphalt temperature is lower, makes the inner asphalt temperature of whole mixing hopper uneven, is unfavorable for operation.
Based on the generation of the problems referred to above, the utility model takes the part forming cavity at sleeve pipe and V-type preventing materials accumulation plate evenly to offer the hole of circulating for flue gas, the high-temperature flue gas that burner is produced flows in above-mentioned cavity through hole, V-type preventing materials accumulation plate is heated, avoids asphalt mixture warm herein and spend low problem.
Consider difficulty of processing and processing cost, select on sleeve pipe, offer six waist-shaped holes, waist-shaped hole can report the amount of flow ensureing flue gas, also can not reduce the installation strength of sleeve pipe, solve problems of the prior art.
When pavement maintenance truck carries out operation under the operating mode of pavement roughness, pavement maintenance truck frame often there will be torsional deformation, and motor is directly fixed in pavement maintenance truck frame can cause engine shell body deformability thus damage; The utility model provides a kind of engine support for stationary engine, and engine support is fixed in pavement maintenance truck frame by three application points (oscillating bearing connection).The deformation quantity avoiding pavement maintenance truck frame torsional deformation 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 1:
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 pavement maintenance truck frame; 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 pavement maintenance truck frame, 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 pavement maintenance truck frame 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.
