Description

A kind of truck car door

Technical field

The utility model relates to a kind of truck car door.

Background technology

During China railways open-top car transportation shipping parcels, need load and unload by the car door of open-top car both sides.As Fig. 1～shown in Figure 2, existing open-top car car door is made up of door-plate 1, bearing pin 2, folding seat 3, door butt 4, link 5 and open-top car top hook 6, hasp 7 etc.Be in the A position during closing of the door, when needing to open car door, open the hasp 7 of door-plate bottom lock door folding 4, car door is that axle center (O place) upset is in the C position for about 150 ° with bearing pin 2, utilize the hook 6 on open-top car top, car door is fixed on the hook, by the car door mouth can freight, unloading operation.

But for a long time owing to be subjected to the restriction of platform height, when open-top car was parked on the platform, as shown in Figure 2, when opening car door and be turned to the B position, car door often was subjected to stopping of platform and can't opens.In order to open or close car door, open-top car need be pushed to outside the platform with locomotive, open or close car door, again with locomotive traction to platform, carry out the handling goods operation.Therefore handling goods is more non-cutting time, wastes energy, and the efficiency of loading and unloading is low.

Summary of the invention

For solving the problem that truck car door when the platform handling goods is difficult to On/Off, the utility model provides a kind of novel railway open-top car car door, by this novel open-top car car door, avoid open-top car need be pushed to the operation that platform carries out the open and close car door in addition, on railroad platform, directly can open or close car door, thereby improve the efficiency of loading and unloading.

For achieving the above object, the utility model is taked following technical scheme: a kind of truck car door, be included in open-top car door-plate that compartment middle part is provided with, the hook that is provided with at the body hinge seat of door-plate upper fixed, fixing fixedly folding on door-plate, at car body top, the hasp that is provided with in the bottom, compartment, it is characterized in that: described body hinge seat is provided with the Long Circle pin-and-hole, links to each other with fixing folding by bearing pin; Described fixedly folding by the bottom link is installed, the lower end of described fixedly folding is welded with activity folding seat, connects an activity folding by activity folding bearing pin on the activity folding seat, described activity folding lower end has boss, with described snap fit; Described activity folding is fastened in the described link when movable link pin is axially gone up upset, and described link colludes on described hook.

Described body hinge seat, fixedly folding, activity folding pairing are provided with.

Described fixedly folding, activity folding are that band steel is made.

The Long Circle pin-and-hole that is provided with on the described body hinge seat and fixedly the circular pin hole in the folding be connected by bearing pin.

The pin-and-hole of described activity folding upper end is formed by the band steel bending, is connected with described activity folding bearing pin.

The utility model is owing to take above technical scheme, it has the following advantages: 1, the utility model adopts the new car door on open-top car, body hinge is by fixedly folding and activity folding combine, the activity folding of bottom of door adopts bearing pin to be connected the lower end of fixedly folding turningly, when opening car door, the activity folding of student's end makes the unlatching radius of door diminish because of overturning up, can avoid stopping of platform building, has improved the open-top car efficiency of loading and unloading.2, the body hinge seat on open-top car car door of the present utility model top adopts novel suspending formula structure, design Long Circle pin-and-hole on the folding seat, can realize that car door had both had within the specific limits moves up and down, also have the car door of making turn over function simultaneously, guarantee the normal opening and closing on platform of open-top car car door.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in detail.

Shown in Fig. 3,4, the utility model adopts fixedly folding to add the fabricated structure of activity folding, and the activity folding can be turned in the fixedly folding, thereby car door upset radius is reduced, and can open or close freely from the platform next door.In a specific embodiment, it comprises the open-top car door-plate 11 of a routine, on the compartment side plate above the door-plate 11, is fixed with two body hinge seats 12 with welding manner, pin-and-hole 13 is arranged on the body hinge seat 12, and be the Long Circle pin-and-hole, shown in Fig. 5,6.Two fixedly foldings 14, the employing band steel is made, be fixed on the door-plate 11 with the welding manner bilateral symmetry, the upper end has circular pin hole, be connected by bearing pin 15 with the pin-and-hole 13 on the body hinge seat 12, make whole car door utilize body hinge seat 12 to adopt bearing pins 15 to be connected and be suspended on the open-top car side plate with fixing folding 14.

Be fixed with the link seat in fixing folding 14 lower body part, link 16 is installed on the link seat.Each fixedly is fixed with activity folding seat 17 with welding manner in the lower end of folding 14, respectively connects an activity folding 19 by activity folding bearing pin 18 on the activity folding seat 17.Activity folding 19 adopts band steel to make with fixedly folding 14 is corresponding.Shown in Fig. 7,8, activity folding 19 upper ends have pin-and-hole 20, are formed by the band steel bending, are connected with activity folding bearing pin 18; The lower end has boss 21, cooperates with the hasp 22 that the bottom, compartment is provided with.Open under the prerequisite of hasp, activity folding 19 is can be resupinate along activity folding bearing pin 18, and activity folding 19 is fastened in the link 16 when upwards overturning, and makes it be unlikely to turn over.

In the foregoing description, the purpose that Long Circle pin-and-hole 13 is set is to guarantee that from another point of view whole car door can move up and down and overturn, if bottom of door is too near or because of reasons such as permanent wheel wearing and tearing of time, car body move down apart from platform, when activity folding 19 is not enough to realize the switch car door, certain distance (effective movable length of pin-and-hole 13) can move up the car door of the state that hangs down naturally, make car door overturn maximum gabarit, realize the switch car door away from the maximum outstanding position of platform.Behind the closing of the door, the hasp that activity folding 19 lower ends are provided with the open-top car bottom pins, and whole car door is locked, and the boss 21 of activity folding 19 lower ends is stuck in the bottom of hasp 22, prevents car door because the upper end is Long Circle pin-and-hole and play upwards.

As Fig. 3～shown in Figure 4, when the open-top car car door was in closed condition, car door was arranged in the position of Fig. 4 A.When needing to open the open-top car car door on platform, at first open the hasp 22 of open-top car bottom of door, car door can be because of angle of the outside naturally upset of action of gravity.With activity folding 19 upset, and entangle with link 16 and to be fixed on the B position.Whole car door flips to the outside, whole car door maximum rotation gabarit this moment (fixedly folding 14 lower ends) is given prominence to the position less than the maximum of platform, whole car door is the position that the center can be turned to C with the O point, utilizes the hook 23 on link 16 and open-top car top car door to be fixed on the position of top C.Thereby realize that the open-top car car door can open or close on platform.

In the various embodiments described above; the structure of each parts, the position is set and connects and all can change to some extent; on the basis of technical solutions of the utility model,, should not get rid of outside protection domain of the present utility model improvement and the equivalents that individual component is carried out.
