Technical field
The present invention relates to the lorry body side door, refer to particularly a kind of railway truck opening device for side door.
Background technology
At present, to be door butt with a door hasp overlap the traditional fixed form of China railways lorry side door cooperates.In the use procedure, side door plate pins folding by left and right sides hasp, opens and closes side door plate and must open or locking left and right sides hasp.But there is following defective in existing railway truck opening device for side door:
One, in Freight Transport goods way, side door plate is subject to the squeezing action of the inner goods of lorry, and friction force increases between door butt and the door hasp, causes the switch gate difficulty, and switch gate also needs extra switch gate to knock instrument, causes the inconvenience of turnover door unlatching.
They are two years old, when the Freight Transport mass freight, for mass freight is effectively fixed, need to use some fixed partss such as rope bolt on the floor underframe for vehicle on the lorry, and present lorry is in order to ensure good sealing effect, reserving gaps in lorry so increase the friction of fixed parts and side door plate, is not destroyed the railway truck opening device for side door in the course of time.
Summary of the invention
Purpose of the present invention will provide a kind of railway truck opening device for side door exactly, and this device does not need extra switch door instrument, handled easily; Can satisfy the use needs of different operating modes, improve the reliability of service of side door opener, improve the economic benefits of transportation efficiency.
The technical scheme that the present invention adopts for achieving the above object is: a kind of railway truck opening device for side door, comprise the side door plate that matches with cabin side wallboard aperture of door, be fixed with the folding bar on the described side door plate, the upper end of described folding bar is hinged with the folding seat by shipping and reselling on another market, described folding seat is fixed on cabin side wallboard aperture of door top, the lower end of described folding bar is hinged with the side door handgrip by shipping and reselling on another market, the upper arm of described side door handgrip cooperates with the handgrip locking bed is nested under the side door plate closed condition, the underarm of described side door handgrip cooperates with the insertion of handle hole seat under the side door plate closed condition, described handgrip locking bed is hinged on the side door plate middle part by shipping and reselling on another market, described handle hole seat is fixed on cabin side wallboard aperture of door bottom.
Further, be arranged with nearside wallboard hole slot and distally wallboard hole slot on the described handle hole seat in parallel, described nearside wallboard hole slot and distally wallboard hole slot can insert with the underarm of side door handgrip respectively under the side door plate closed condition and cooperate.
Again further, the below that is positioned at the tight seat of handle lock on the described side door plate also is fixed with the handgrip bracket, and described handgrip bracket cooperates with the underarm body clamping of side door handgrip under the side door plate closed condition.
Again further, described folding seat, folding bar, side door handgrip, handgrip locking bed and handle hole seat are provided with two covers, are arranged symmetrically in the both sides of side door plate.
Again further, the middle part of described side door plate is fixed with the handgrip block, and described handgrip block cooperates with the upper arm butt of side door handgrip under the side door plate opening.
Usefulness of the present invention is: designed side door plate itself does not need extra switch door instrument, handled easily with the side door handgrip; The different gap crack between a door and its frame that needs for transport point has the two-stage locking functions, can satisfy the use needs of different operating modes, improves the reliability of service of opening device for side door, has improved the economic benefits of transportation efficiency.Simultaneously, the present invention is simple in structure, easy to make, easy to use, extends to the transformation of opening the door of corresponding vehicle side, has broad application prospects.

The specific embodiment
In order to explain better the present invention, further illustrate main contents of the present invention below in conjunction with specific embodiment, but content of the present invention not only is confined to following examples.
Railway truck opening device for side door shown in the figure, comprise the side door plate 3 that matches with cabin side wallboard 9 aperture of doors, the bilateral symmetry of side door plate 3 is welded with folding bar 4, the upper end of each folding bar 4 is hinged by the 2 and folding seats 1 of shipping and reselling on another market, folding seat 1 is fixed on cabin side wallboard 9 aperture of door tops, the lower end of each folding bar 4 is hinged by the 2 and side door handgrips 6 of shipping and reselling on another market, the upper arm of side door handgrip 6 under side door plate 3 closed conditions with 5 nested cooperations of handgrip locking bed, handgrip locking bed 52 is hinged on side door plate 3 middle parts by shipping and reselling on another market.
The underarm of side door handgrip 6 inserts with handle hole seat 8 and cooperates.Handle hole seat 8 is weldingly fixed on cabin side wallboard 9 aperture of door bottoms, parallel nearside wallboard hole slot 8a and the distally wallboard hole slot 8b of offering on it, nearside wallboard hole slot 8a and distally wallboard hole slot 8b can insert with the underarm of side door handgrip 6 respectively under side door plate 3 closed conditions and cooperate.
Working process of the present invention is as follows:
Such as Fig. 1, Fig. 2 and shown in Figure 4, when railway truck during at normal condition of service, for guaranteeing that the side door opener has good sealing property, this moment, side door handgrip 6 underarms inserted in the nearside wallboard hole slot 8a, side door handgrip 6 is by the combined action of handgrip bracket 7 and handgrip locking bed 5, can force side door plate 3 and framed side wallboard 9 to fit tightly good sealing effect.
Such as Fig. 1, Fig. 3 and shown in Figure 4: when the railway freight-car transporting mass freight, for mass freight is effectively fixed, often need to use some fixed partss such as rope bolt on the floor underframe for vehicle, need like this to reserve between side door plate 3 and the framed side wallboard 9 some slits, so that steel rope wears out in the lorry car is fixing, this moment, side door handgrip 6 underarms inserted in the wallboard hole slot 8b of distally, make between side door plate 3 and the framed side wallboard 9 and leave the gap, satisfying steel rope can pass and can not cause damage to side door plate 3 from aperture of door, satisfies the needs of different goods transports.
As shown in Figure 5 and Figure 6: when needs side door plate 3 is opened, elder generation's rotary handle locking bed 5 gets loose it from side door handgrip 6 upper arm, then rotate side door handgrip 6, make side door handgrip 6 underarms leave nearside wallboard hole slot 8a or the distally wallboard hole slot 8b of handle hole seat 8, until side door handgrip 6 upper arm are blocked by handgrip block 10, get final product turnover side door-plate 3 this moment, thereby open the railway truck side door.
