Description

Tool for mounting spring of locomotive tracting motor

The utility model relates to the manual connection instrument of end finger spring on a kind of locomotive traction motor.

Present locomotive traction motor normal end finger spring fracture that takes place in utilization, behind the spring fracture, the one group of brush in one group of positive side of motor and bottom certainly will break away from brush handle and fall down and hit casing, thereby major loop ground connection is taken place.One group and the one group of brush of face of tossing about do not have thrust after because of the end finger spring fracture on the face, cause surge of current generation ring fire, even soft landing occur.Behind the end finger spring fracture, change spring quite difficulty, especially motor top and these the two groups of brush springs of face of tossing about under the state that motor does not fall to repairing, because the restriction that is subjected to the locus is with common combination pliers, instruments such as screwdriver can't be changed smoothly.Now, changing bottom and these two groups of end finger springs of positive side, is with a crude iron silk, and front end is bent a hook, and one people draws a people holding up snap hook to hang up during installation, accidentally very easily causes industrial injury; And top and the face of tossing about have to be pulled down whole brush holder for these two groups, again brush holder is loaded onto after installing spring, like this, need consuming time are installed more than 1 hour, often cause the late outbound of locomotive because of changing an end finger spring.

The purpose of this utility model is to provide a kind of mounting tools of installation locomotive traction motor end finger spring easily and fast.

For reaching above-mentioned purpose, the utility model adopts following technical scheme: it comprises handgrip, rest pin, drag hook, drag hook handle and two fulcrum pin, it is characterized in that: the position that drag hook handle upper support pin passes is a curved groove; Groove is " └ " shape.

The utility model compared with prior art has following advantage:

1, installs rapidly, can be used for any one group of end finger spring,, adorn a spring and only need 1-2 minute if can skillfully use this instrument;

2, safety, reliably, do not have spring problem such as hurt sb.'s feelings.

Accompanying drawing is the utility model structural representation.

The utility model is described in further detail below in conjunction with accompanying drawing:

Drag hook (4) is hook-shaped, be connected as a single entity with drag hook handle (1), drag hook handle (1) is placed in by rest pin (2) between two fulcrum pin (6) of handgrip (5), and the position that drag hook handle (1) upper support pin (2) passes is one " └ " shape groove (3).When the utility model uses, earlier with the hook of end finger spring one end below the brush carrier end hang up properly, the hook of the spring other end and the drag hook of instrument (4) hang up, two fulcrum pin (6) with instrument place end finger to hang on the cross bar of spring again, the right hand is firmly held drag hook handle (1) and handgrip (5) with a firm grip, and at this moment the spring length that is stretched is fulcrum with fulcrum pin (6) again, the right hand slightly deflection one angle of drag hook handle (1) and handgrip (5) anticlockwise direction of holding with a firm grip, spring can hang up and install.

Claims

1, a kind of mounting tools of locomotive traction motor end finger spring, it comprises handgrip, rest pin, drag hook, drag hook handle and two fulcrum pin, it is characterized in that: the position that drag hook handle (1) upper support pin (2) passes is a curved groove (3).

2, the mounting tools of locomotive traction motor end finger spring according to claim 1 is characterized in that: groove (3) is " └ " shape.
