Description

Portable subway train cab emergency locking special tool

Technical Field

The utility model relates to an emergent locking tool technical field, in particular to emergent locking specialized tool of portable subway train cab.

Background

The product belongs to a non-standard tooling professional tool series, so the product follows the technology of non-standard tooling in the design research and development process. Tooling: refers to professional tools, dies, non-standard cutters, non-standard measuring tools and the like used in the production process of products. The positioning requirement of the professional tool refers to the process that the tool occupies the correct position in the using process. Clamping: fixing the tool after positioning, and keeping the fixed position unchanged during the use process.

The principle of nonstandard frock tool design: 1. the stability and the reliability of workpiece positioning in the using process are met; 2. enough bearing or clamping force is provided to ensure the construction process of the workpiece on the tool clamp; 3. simple and quick operation in the clamping process is met; 4. the quick-change structure of the vulnerable parts is needed, and other tools are not needed when the conditions are sufficient; 5. the reliability of repeated positioning of the clamp in the adjusting or replacing process is met; 6. the complex structure and the high cost are avoided as much as possible; 7. standard parts with reliable quality in the market are selected as far as possible to form parts; 8. the safety regulation of the clamp using state or region is met; 9. the design scheme follows the principle of priority selection in sequence of manual operation, pneumatic operation, hydraulic operation and servo operation; 10. the serialization and standardization of products inside the company are formed.

The 'facility fault handling guidance' of the subway provides that when a side door of a cab of the electric passenger car cannot be closed, a driver confirms whether a shifting fork and a locking cam on a rotary lock of a door locking device are in a locking position or not according to an emergency fault handling method. If the door is in the locking position, a driver presses the unlocking shifting piece downwards with force to enable the locking concave point of the shifting fork to leave the locking cam, and the side door is closed again after manual unlocking. If the positions of a shifting fork and a locking cam on the rotary lock are normal or the vehicle door can not be locked after the above treatment, a driver reports to the dispatching to request the dispatching station personnel to assist in holding the vehicle door, and the vehicle is operated to the terminal station to quit the service according to the dispatching command speed limit of 45km/h and 60 km/h.

Because the door lock of the side door of the cab of the electric passenger car is a mechanical locking device, the failure of locking of the side door of the cab is difficult to avoid in the normal use process, when the failure of locking of the side door of the cab occurs in the electric passenger car in operation, the whole train is treated according to the regulations and must be caused at a later point, the normal operation order is influenced, and therefore an emergency locking tool for the side door of the cab of the electric passenger car is required to be used as a common spare tool.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model aims to provide a portable subway train cab emergency locking specialized tool, when the side door can not be closed and the fault happens, the driver can handle with the tool to avoid the late point influence that causes consequently, have simple structure, convenient and practical's characteristics.

In order to realize the purpose, the utility model discloses a technical scheme is:

the utility model provides an emergent locking specialized tool of portable subway train cab, includes snap ring 2 and kayser 3 that can be fixed in the interior handrail post of automobile body fast, snap ring 2 and kayser 3 between link to each other through strong connecting band 1.

The clamping lock 3 is a clamping ring with an opening at one end, and an anti-hand lock catch 4 for locking is arranged at the opening.

The snap ring at the position of the snap lock 3 is of a rotatable structure.

The diameters of the snap ring 2 and the snap ring of the snap lock 3 are the same.

The utility model has the advantages that:

when a subway train operates, the passenger flow is large, and drivers and passengers need to get off through a side door of a cab to watch the external conditions of the whole train when the train stops at each station. Therefore, the side door system of the cab is the key influencing the safe and on-spot running of the whole subway train. When this instrument had mainly solved "driver's cabin side door secondary lock trouble", the driver can utilize this instrument to carry out the emergent clearance of trouble fast to avoid the shut down time overlength and cause the great influence that whole line train late point brought, ensure that the train is safe just in operation.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The process requirement of the tooling processing is as follows:

general technical requirements are as follows: 1. blanking a blank of a raw material (steel); 2. cutting the appearance of the glass substrate by a laser cutting machine; 3. processing the surface of the part (electroplating treatment); 4. assembling the movable fastener; 4. the strong rubber band is assembled in an integral body.

Part edge angle: 1. and (4) performing R-chamfering deburring treatment on the non-injection fillet.

The technical parameters are as follows: the tool type is customized for a non-standard part; the material of the tool adopts galvanized steel sheets and a strong connecting belt 1 (wide plate); the external dimension is 300 multiplied by 180 Mm; the weight is 0.3 Kg; stretching length 260 MM; the bearing tension is 17Kg of four-strand ball clamp.

The utility model discloses a theory of operation:

when the driver side door fails and cannot be closed, the clamping lock with one end foldable is fixed at the holding rod of the driver side door, the strong connecting band is pulled, the round clamping ring at the other end is directly sleeved into the door opening handle of the driver side door, and the driver side door is fixed in a certain range by fixing the two ends and pulling the middle strong connecting band, so that the condition of invading the subway equipment boundary cannot be generated.
