Description
Technical field
The present invention relates to lorry door, refer to that a kind of railway truck higher to sealing requirements slides embedded car door particularly.
Background technology
Along with the development of China Railway technology, quick dispatch shipping will be the developing direction of railway freight.Existing lorry door is mainly divided into be split cliding door and splits rotary type vehicle door two class, split cliding door to be generally made up of two fan doors, bottom of door is equipped with roller, roller rolls in orbit, exit door is driven to realize switch in external force, car door top is equipped with slideway, can prevent car door from toppling over; Split rotary type vehicle door to be also made up of two fan doors, car door is connected with doorframe by hinge.Above-mentioned two kinds of car doors are when closing, and car door is in normal locking states all to have door lock or special purpose device to ensure.But there is following shortcoming in these two kinds of car doors: split cliding door in off position time and car body localized contact, the stressed parts of car door and car body produce clash into fragile; Split when rotary type vehicle door is in opening and need larger convolution space.Further, above-mentioned two kinds of door sealing poor-performings, all can not stop the erosion of sleet to goods completely, because the size of the restriction car door by structure can not design too large.
Summary of the invention
Object of the present invention is exactly to provide a kind of railway truck simple and reliable for structure, that sealing property is splendid, car door size can design larger to slide embedded car door.
For achieving the above object, the railway truck designed by the present invention slides embedded car door, and be arranged on vehicle body side wall, above doorframe between slideway and below slideway, it comprises a body, and its special character is:
The both sides of described door body are symmetrically fixed with upper support seat and lower support seat up and down, rotating hollow locking lever is provided with in the mounting hole that described upper support seat is corresponding with lower support seat, rotatable hingen bar is provided with in described hollow locking lever, the two ends up and down of described hingen bar are fixed with crank throw and lower crank throw respectively, the end of described upper crank throw and top slideway bearing fit, the end of described lower crank throw and below slideway bearing fit, the shaft of described hingen bar is fixedly connected with jug; Also drive upper crank throw and lower crank throw to rotate by handle driving gate hinged arm, the direction translation of Men Tixiang doorframe can be made;
The midperpendicalar position on the lower side of described door body is provided with direction door lock, the both sides extension and contraction control end of described direction door lock is connected with the one end of the pull bar that matches respectively, the other end of described pull bar is connected with locking cam by bearing pin, described locking cam is fixedly set on the hollow locking lever corresponding with draw rod positions, the doorframe outside described locking cam is provided with the lock matched with it; Drive pull bar to move to door body both sides by direction door lock, locking cam and hollow locking lever can be made to rotate, and then locking cam is engaged with lock, thus locking door body.
One of preferably, the end of described upper crank throw is coordinated with top slideway by slide block or roller, and the end of described lower crank throw is connected with wheel stand by bearing pin, and described wheel stand coordinates with below slideway.Like this, by setting up slide block, roller and wheel stand, can sliding resistance be reduced, making the contact resistance of upper and lower crank throw between upper and lower slideway less, sliding easier.
Preferably two, the both side surface of described doorframe is provided with the centering orienting lug matched with the both sides inner face of door body.Like this, when the direction translation of Men Tixiang doorframe, under the effect of centering orienting lug, a body can be more easily made to enter doorframe.
Further, the both sides inner face of described door body is provided with energy disperser.Like this, can prevent the body from directly bumping against side wall when door body is opened, thus avoid the part of car door impaired.
Further, the vehicle body side wall of described door body side is provided with stopping seat, described stopping seat can limit its sliding scale when door body opening, can prevent the body from departing from slideway because of faulty operation.
Further, one end of described below slideway is provided with registration device, and described registration device is fixedly connected with corresponding wheel stand when door body opening.Like this, when door body is in opening, be fixed on the slideway of below by car door with registration device, a body can be avoided to slide affects loading and unloading operation.
Further, the two ends up and down of described hingen bar are fixedly linked respectively by key and upper crank throw and lower crank throw, and described handle is fixedly connected with hingen bar by bolt and nut component, and its structure is simple, and stable connection is reliable.
Again further, the extension and contraction control end of described direction door lock is connected with one end of pull bar by screw structure.Adopt screw structure to drive pull bar, the lock function of door lock can be made more stable and firm.
Again further, locking cam is equipped with on described hollow locking lever top also fixed cover, the doorframe outside this locking cam is also provided with the lock matched with it.Like this, can from door body both sides upper and lower symmetrical locking door body, guarantee sealing more reliable.
Again further, described energy disperser, direction door lock, upper support seat and lower support seat adopt bolt or rivet to be fixedly connected with door body.Like this, Assembly &Disassembly is very convenient.
Principle of work of the present invention is such: when needing closed door, promoting door body makes wheel stand roll on the slideway of below, until the alignment of Men Tiyu doorframe, then pulling handle makes hingen bar drive upper crank throw and lower crank throw to rotate, make direction translation in Men Tixiang doorframe, after a body major part enters doorframe, rotate the handle on direction door lock, direction door lock drives the pull bar matched with it to move to door body both sides by screw structure, locking cam and hollow locking lever are rotated, and then locking cam is engaged with lock, thus locking door body.
The invention has the advantages that: the embedded automobile door structure of designed slip is simple, its body to be arranged on vehicle body side wall, above doorframe between slideway and below slideway, a body lower edge can be kept concordant with doorframe inner horizontal, guaranteeing that a body entirety is held embeds in doorframe, uniform force is stablized, and car door and car body do not clash into.When car door is in closed condition, because door body enters in doorframe, the external side of door is substantially concordant with the horizontal surface outside side wall, the car door weight overwhelming majority is born by car body, and direction door lock that locking cam can be made to engage with lock is closely firm, therefore 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, can reduce air resistance when vehicle high-speed runs simultaneously.When car door is in opening, it occupies little space, and therefore the design size of door body can correspondingly increase, and is beneficial to do mechanization operation, is convenient to realize goods quick despatch and cleaning.
