Description
Technical Field
The invention relates to a field self-propelled kitchen truck with wingspan linkage double doors, which can realize linkage opening and closing of an upward-turning door and a downward-turning door and can realize independent opening and closing control of the upward-turning door so as to greatly improve the use adaptability of the field self-propelled kitchen truck.
Background
At present, the function of traveling of equipment can be realized to open-air self-propelled kitchen truck to satisfy open-air and emergency rescue demand, the open-air self-propelled kitchen truck of current generally contains the automobile body, realizes the automobile chassis of the function of traveling promptly and set up in the carriage that opens the door after taking on the automobile chassis, then carry out the setting of corresponding cooking instrument in the carriage again. The open-air self-propelled kitchen truck of current has closed with the open-air, wherein, the use operation space of the multiplicable railway carriage of open-air self-propelled kitchen truck to be favorable to the oil smoke to discharge, therefore open-air self-propelled kitchen truck begins to be widely used.
The present open field self-propelled kitchen truck is generally provided with corresponding opening on its carriage, then is provided with respectively in the upper and lower end of its opening part and can open and close the span door, turn-up door and turn-down door promptly, at the opening of span door, turn-up door opens upwards promptly, turn-down door opens the back downwards, alright effectively increase the use operating space in the carriage of field self-propelled kitchen truck, simultaneously, in order to guarantee the bearing capacity of turning down the door, present turning down door is opening the back downwards, still can generally have a plurality of corresponding bracing piece downwards fixing device.
In order to ensure that the upturning door and the downturning door of the open field self-propelled kitchen vehicle can be smoothly driven, the traditional driving method is as follows: the upper and lower ends of the carriage are respectively provided with a driving hydraulic cylinder, the upper flap door is driven by the driving hydraulic cylinder arranged at the upper end of the carriage, and the lower flap door is driven by the driving hydraulic cylinder arranged at the lower end of the carriage. Therefore, two sets of driving hydraulic cylinders are needed, and the manufacturing cost, the maintenance requirement and the use failure rate are relatively high; the most important is that the cylinder body one end of upper portion drive pneumatic cylinder can only single-end hang and articulate the top at the carriage, and it is big except that the oil pipe arranges the degree of difficulty, still has certain use safety hidden danger, for example when the suspension articulated end of drive pneumatic cylinder appears not hard up scheduling problem, just probably the incident appears. Therefore, the existing driving method is as follows: the hydraulic linkage driving mechanism is directly arranged at the bottom of the carriage, then the linkage driving mechanism is arranged between the upper turnover door and the lower turnover door, when the hydraulic linkage driving mechanism is used, the switch of the lower turnover door is driven independently through the driving hydraulic cylinder, and then the switch of the upper turnover door is driven synchronously under the driving of the linkage driving mechanism, so that the use of one set of hydraulic cylinder can be reduced, and the defects existing in the upper arrangement of the driving hydraulic cylinder can be effectively overcome.
However, the technical scheme of synchronously opening and closing the upper turnover door and the lower turnover door by a set of driving hydraulic cylinder and a linkage driving mechanism has the following obvious defects: 1) During the traveling process of the kitchen truck, particularly during the traveling process with higher speed, as the upturned door and the downturned door have larger wind-receiving areas, larger stress exists under flowing air pressure of the upturned door and the downturned door, the downturned door is directly fixed by the driving hydraulic cylinder, and the stress of the upturned door needs to be transmitted to the downturned door through the linkage driving mechanism and then is finally transmitted to the driving hydraulic cylinder, so that stress concentration easily occurs at each connecting node of the linkage driving mechanism and the connecting part of the downturned door and the driving hydraulic cylinder, and finally the mechanism is deformed and loses efficacy; 2) The upper turnover door and the lower turnover door can be opened and closed simultaneously, and once in rainy weather, the upper turnover door and the lower turnover door can only be selected to be opened, so that the oil smoke is difficult to be discharged timely, and the use adaptability of the kitchen truck is reduced.
Therefore, the synchronous switch linkage driving of the upper turnover door and the lower turnover door and the independent switch driving of the upper turnover door can be effectively realized, so that the use adaptability of the equipment is improved; the invention also discloses a field self-propelled kitchen truck with a winged-unfolding linkage double-door, which can effectively ensure the structural stability of a driving hydraulic cylinder and a linkage driving mechanism, thereby effectively ensuring that equipment can stably run for a long time.
