Abstract

The utility model provides an apron board locking structure for a high-speed motor train unit, which belongs to the technical field of vehicles and is used for solving the problem in installing an apron board. The utility model adopts the technical scheme that the locking structure consists of an insert pin lock and a foldout, wherein, the lock core of the insert pin lock is fixed on the apron board and positioned adjacent to the upper edge of the apron board, a lock sleeve is connected with the longitudinal beam of the chassis of a carriage or equipment inside the bay through a bracket, and two sheets of the foldout are connected with the lower edge of the apron board and the longitudinal beam of the bottom plate of the equipment bay respectively. In the utility model, the apron board isfixed to the two sides of the equipment bay using the insert pin lock and the foldout, the insert pin lock can be conveniently unlocked and locked by using a key, and the apron boar and the longitudinal beam of the bottom plate are connected through the foldout, thereby ensuring more flexible unlocking and locking of the apron board. The locking structure not only ensures reliable connection between the apron board and the carriage, but also contributes to convenient and rapid disassembly of the apron board.

Description

A kind of EMU skirtboard lock structure

Technical field

The utility model relates to the lock structure of a kind of EMU compartment down either side guar plate (equipment compartment sidewall), belongs to the vehicle technology field.

Background technology

Many equipment of train are installed in the equipment compartment of bottom, compartment; the two side of equipment compartment; the guar plate (as shown in Figure 1) that is the compartment down either side claims skirtboard usually; skirtboard belongs to the non-bearing member; its effect is the air resistance that reduces in the train operation; reinforcement also plays decoration function to the car body profile simultaneously to the protection of various devices in the equipment compartment, makes it more attractive in appearance.

Be installation and the maintenance that makes things convenient for equipment, the skirtboard of train is divided into two kinds of fixed skirt and movable skirtboards, and the former directly is welded on the compartment, adopts overlap joint between the latter and the compartment or fasten removably such as to connect and be connected.Skirtboard on the EMU is different from the skirtboard of other vehicles, be arc plate body by the disposable welding fabrication of Aluminum Hollow section bar of in light weight, good looking appearance, existing overlap joint or fasten the mode of connecing and all should not adopt, so must the novel skirtboard lock structure of development, make skirtboard be connected and be convenient to dismounting with the compartment is reliable.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of skirtboard that makes reliably to be connected with the compartment and easy-to-mount EMU skirtboard lock structure.

Problem described in the utility model realizes with following technical proposals:

A kind of EMU skirtboard lock structure, form by latch lock and folding, the lock core of described latch lock is fixed on the skirtboard and is positioned near the skirtboard upper limb, lock tube is connected with compartment underframe longeron or below deck equipment by support, and two pages of sheets of described folding are connected with the lower edge of skirtboard and the underframe longitudinal member of equipment compartment respectively.

Above-mentioned EMU skirtboard lock structure, described latch lock and folding all are provided with a plurality of, and they are uniformly distributed on the skirtboard along This train is bound for XXX, also are provided with the safety hook that connects skirtboard and below deck equipment between adjacent two latches lock.

The utility model utilizes latch lock and folding that skirtboard is fixed in the both sides of equipment compartment, and latch is locked available key and opened easily and locking, is connected by folding between skirtboard and the underframe longitudinal member, makes the unlatching of skirtboard and locking more flexible.The effect of safety hook is to hook skirtboard under the situation that the latch lock lost efficacy, and tries to avert accidents.The utility model not only can make skirtboard reliably be connected with the compartment, and can make the dismounting of skirtboard convenient, quick.

Below in conjunction with accompanying drawing the utility model is further specified.

Fig. 1 is a skirtboard installation site scheme drawing;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is the scheme of installation of latch lock;

Fig. 4 is the scheme of installation of folding;

Fig. 5 is the scheme of installation of safety hook;

Fig. 6 is the structural representation of safety hook.

Each label is among the figure: 1, underframe longeron; 2, equipment compartment support; 3, skirtboard; 4, underframe longitudinal member; 5, equipment ceiling board; 6, latch lock; 7, safety hook; 8, folding; 9, below deck equipment.

The specific embodiment

Referring to Fig. 2～Fig. 4, this skirtboard lock structure comprises latch lock 6, folding 8 and safety hook 7, the lock tube of latch lock 6 is connected with compartment underframe longeron 1 or below deck equipment 9 by support, the support upper end has and compartment underframe longeron 1 or below deck equipment 9 bonded assembly risers, and the lock tube of latch lock 6 is fixed in the support lower end.Lock core is fixed in skirtboard near the upper limb place.The hanging scroll of two pages of sheets of folding 8 by coupling, articulate, a page or leaf sheet that links to each other with hook is connected with the lower edge of skirtboard 3, and a page sheet continuous with hanging scroll is connected with equipment ceiling board longeron 4.Skirtboard 3 uses general four jiaos of key operated or lockings of passenger vehicle, and Fig. 2 is the equipment compartment inside structure.In Fig. 3, skirtboard 3 is fixed on the below deck equipment 9 by latch lock 6, and this is main connection mode, also can will be fixed on the compartment underframe longeron 1.For install, maintenance, the equipment of handling, observe under the car be convenient, the equipment compartment both sides are provided with movable skirtboard and fixed skirt (also all employing activity skirtboard), and various inspection doors, porthole are set.Movable skirtboard is provided with the locking mechanism that special-purpose four jiaos of keys open and close, and can be easy to open and close.

Referring to Fig. 5, between two latches locks, be provided with safety hook 7, safety hook 7 links together skirtboard 3 and below deck equipment 9, and safety hook can hook skirtboard and tries to avert accidents under the situation that the latch lock lost efficacy.Among Fig. 5, safety hook 7 is fixed on the below deck equipment 9, and skirtboard 3 is provided with supporting with it hook cross bar, and safety hook 7 is in the non-stress state after the skirtboard installation, and hook there is no overlap joint with the hook cross bar.In case latch lock 6 lost efficacy, skirtboard is outwarded winding laterally by skirtboard below folding, and the hook cross bar just " is hooked " by safety hook, and the restriction skirtboard is to the displacement in the car body outside.Remove safety hook and only need survey the bossing that promotes the hook top with hand in car body according to lever principle, " hook " of hook just can break away from the hook cross bar, becomes the state of complete opening.

When skirtboard all adopts the utility model; fleetline fully enclosed equipment compartment of the common composition of skirtboard, front and back bulkhead plating, equipment ceiling board 5, underframe longitudinal member 4 and floor compartment; between each position of equipment compartment " the dead connection " of no solder type; all be that the detouchable parts connect; not only make things convenient for the assembling and the replacing of parts; also meet the operating aerodynamics of car body, to the protection of equipment below deck equipment also very comprehensively.
