Description
Technical field
The present invention relates to lorry door, refer to particularly a kind of to the higher railway truck of the sealing requirements embedded car door that slides.
Background technology
Along with the development of China Railway technology, the quick dispatch shipping will be the developing direction of railway freight.Existing lorry door mainly is divided into to be split cliding door and splits rotary type vehicle door two classes, splitting cliding door generally is comprised of two fan doors, bottom of door is equipped with roller, roller rolls in orbit, drive exit door in external force and can realize switch, car door top is equipped with slideway, can prevent that car door from toppling over; Split rotary type vehicle door and also be comprised of two fan doors, car door is linked to each other with doorframe by hinge.Above-mentioned two kinds of car doors all have door lock or isolated plant to guarantee that car door is in normal locking states when closing.But there is following shortcoming in these two kinds of car doors: split cliding door and contact with car body is local in off position the time, the stressed parts of car door clash into fragile with the car body generation; Need larger convolution space when splitting rotary type vehicle door and being in opening.And above-mentioned two kinds of door sealing poor-performings all can not stop sleet fully to the erosion of goods, because the size of the restriction car door that is subjected to structure can not design too greatly.
Summary of the invention
Purpose of the present invention is exactly that a kind of railway truck simple and reliable for structure, that sealing property is splendid, the car door size can design greatlyr embedded car door that slides will be provided.
For achieving the above object, the designed railway truck of the present invention embedded car door that slides, be installed on the vehicle body side wall, slideway above the doorframe and below between the slideway, it comprises a body, its special character is:
The both sides of described door body are symmetrically fixed with up and down upper support seat and lower support seat, be provided with rotating hollow locking lever in the described upper support seat mounting hole corresponding with the lower support seat, be provided with rotatable hingen bar in the described hollow locking lever, the up and down two ends of described hingen bar are fixed with respectively crank throw and lower crank throw, the end of described upper crank throw and top slideway bearing fit, the end of described lower crank throw and below slideway bearing fit, captive joint jug on the shaft of described hingen bar; By handle driving gate hinged arm and the upper crank throw of drive and the rotation of lower crank throw, can make the translation of Men Tixiang doorframe direction;
The midperpendicalar of described door body is equipped with direction door lock in the position on the lower side, the both sides extension and contraction control end of described direction door lock links to each other with an end of the pull bar that matches respectively, the other end of described pull bar links to each other with locking cam by bearing pin, described locking cam is fixedly set on the hollow locking lever corresponding with draw rod positions, is provided with the lock that matches with it on the doorframe in the described locking cam outside; Drive pull bar to door body two side shiftings by direction door lock, can make the rotation of locking cam and hollow locking lever, and then make locking cam and lock engagement, thus locking door body.
As one of preferred version, the end of described upper crank throw cooperates with the top slideway by slide block or roller, and the end of described lower crank throw links to each other with wheel stand by bearing pin, and described wheel stand cooperates with the below slideway.Like this, by setting up slide block, roller and wheel stand, can reduce sliding resistance, make the contact resistance of upper and lower crank throw between the upper and lower slideway less, it is easier to slide.
As two of preferred version, the both side surface of described doorframe is provided with the centering orienting lug that matches with the both sides inner face of door body.Like this, when the translation of Men Tixiang doorframe direction, under the effect of centering orienting lug, can more easily make a body enter doorframe.
Further, the both sides inner face of described door body is provided with energy disperser.Like this, when the door body is opened, can prevent that the body from directly bumping against side wall, thereby avoid the part of car door impaired.
Further, be provided with stopping seat on the vehicle body side wall of described Men Tiyi side, described stopping seat can limit its sliding scale when door body opening, can prevent that a body breaks away from slideway because of faulty operation.
Further, an end of described below slideway is provided with registration device, described registration device when door body opening with corresponding wheel stand captive joint.Like this, when the door body is in opening, with registration device car door is fixed on the slideway of below, can avoid a body to slide affects loading and unloading operation.
Further, the up and down two ends of described hingen bar are fixedly linked by key and upper crank throw and lower crank throw respectively, and described handle is captiveed joint with the hingen bar by bolt and nut component, and it is simple in structure, and stable connection is reliable.
Again further, the extension and contraction control end of described direction door lock links to each other with an end of pull bar by screw structure.Adopt screw structure to drive pull bar, can make the lock function of door lock more stable and firm.
Again further, locking cam is equipped with on described hollow locking lever top also fixed cover, also is provided with the lock that matches with it on the doorframe in this locking cam outside.Like this, can be from door body both sides symmetrical locking door body up and down, guarantee that sealing is more reliable.
Again further, described energy disperser, direction door lock, upper support seat and lower support seat adopt bolt or rivet to captive joint with the door body.Like this, Assembly ﹠Disassembly is very convenient.
Principle of work of the present invention is such: when needing closed door, promote a door body make wheel stand below slideway roll, until Men Tiyu doorframe alignment, then pulling handle makes the hingen bar drive upper crank throw and the rotation of lower crank throw, make direction translation in the Men Tixiang doorframe, after a body major part enters doorframe, handle on the rotation direction door lock, direction door lock drives the pull bar match with it to door body two side shiftings by screw structure, make the rotation of locking cam and hollow locking lever, and then make locking cam and lock engagement, thereby locking door body.
The invention has the advantages that: the embedded automobile door structure of designed slip is simple, its body is installed on the vehicle body side wall, slideway above the doorframe and below between the slideway, can keep a body lower edge concordant with the doorframe inner horizontal, guaranteeing that a body integral body is held embeds in the doorframe, stressed uniform and stable, and car door and car body do not clash into.When car door is in closed condition, because the door body enters in the doorframe, the external side of door is substantially concordant with the horizontal surface outside the side wall, the car door weight overwhelming majority is born by car body, and direction door lock can make the engagement of locking cam and lock closely firm, so the leak tightness of locking door body tail gate is very good, can guarantee that the parts power that is impacted is little, cargo transportation security is reliable, the air resistance in the time of can reducing the vehicle high-speed operation simultaneously.When car door was in opening, it occupied little space, and therefore the design size of door body can correspondingly increase, and is beneficial to do mechanization operation, was convenient to realize goods fast loading and unloading and cleaning.
