Abstract

A trolley hanging line drum wheel assembly consists of a drum wheel mounted on wire ropes and a hanging wire that can be hung and connected to the drum wheel and the lower end of the hanging wire can be clamped to a power cable 7. The hanging wire has a pull rod 3 and the lower part of the pull rod 3 is fastened with a clamping ring 4; below the clamping ring 4 are two symmetrically connected clamps 5 on the left and right. A pin shaft 6 is provided through the holes in the lower part of the two clamps. A pulling rod 10 is provided at one end of the pin shaft to control the engagement and disengagement of the clamps 5. The pulling rod 10 is connected to the pin shaft 6 with a pin 9. The drum wheel consists of a left wheel and a right wheel mutually engaged with each other. Both the left and right wheels are furnished with a half-lining and two ends of the half-lining are connected to a stop piece. The stop piece has a projecting top and a concave opening. The utility model is applicable for the hanging of power cables of trolleys and electric locomotives.

Description

Electric car messenger wire drum assembly set

The utility model relates to the device that draws the extension electric wire, particularly draws the device of hanging electric car and electric locomotive electric wire.

Trackless trolley car and electric locomotive travel way top is provided with a special-purpose transmission of electricity electric wire, and this electric wire is hung on its top and has set up steel strand through drawing to mount to put to be drawn.Draw the device of hanging this electric wire by component set-ups such as connecting panel, bolt, nuts in the known technology, its use, I﹠M are convenient inadequately, and cost is also higher, and this device that electric wire is combined with steel strand is fastening, the upheaval of electric wire can cause the steel strand upheaval, and vice versa.

The purpose of this utility model is to provide use with easy for installation for overcoming above-mentioned defective, is convenient to maintenance, lower-cost a kind of electric car messenger wire drum assembly set.

Technical solution of the present utility model is coupled to messenger wire drum, that the lower end can press from both sides pull the wire by the drum that can be placed on steel strand and can hanging to be formed, and its special character is:

Described messenger wire has a pull bar, and the pull bar bottom is fixed with pressure ring, is linked with symmetrical two below the pressure ring and hangs folder, and two hang in the perforation of folder bottoms and are provided with bearing pin, and bearing pin one end is provided with control and hangs the tommy bar of folder opening and closing and sell and be coupled to bearing pin pivotly;

Described drum is made of with right half wheel is chimeric mutually a left side half wheel, a left side half wheel and right half wheel respectively have its two ends of a half-axile sleeve and respectively are linked with a catch, and catch one end of a left side half wheel is provided with the protruding top other end and is provided with recess and matches with corresponding recess and protruding top that corresponding catch is partly taken turns on the right side respectively.

Its bottom of described tommy bar is trapezium structure, and does not wait with respect to the distance of the described pin at pivot point place on each limit of trapezium structure, promptly is divided into " closely selling the limit " and " finding a good sale in the limit "; When rotating tommy bar " to find a good sale in the limit " described relatively the extension folder, this limit leans and hangs folder, makes to hang the folder clamping, and when " closely selling the limit " hung folder relatively, this limit was left and hung folder, makes to hang folder and open one or two and hang and be clipped in free reset mode and release elasticity tension and locate to open shape.

The right side half wheel that constitutes the drum of the utility model can partly be taken turns complete similar shape with a left side, it according to the axle center rotate 180 degree just can with a left side partly take turns chimeric, chimeric after, respectively pinch left and right half wheel folding with left hand and right hand and break off with the fingers and thumb, can left and right half wheel separation.The utility model optimal way is that right partly wheel is taken turns similar shape in fact fully with a left side half.For making a left side half wheel and the right side take turns partly that chimeric firmly its protruding top root and recess outer end are provided with corresponding one section inclined-plane, make to become to draw the button shape when chimeric, moreover left and right partly the wheel is provided with respective step shape structure in the half-axile sleeve place.Left and rightly partly take turns mutually when chimeric, the two halves axle sleeve is involutory, forms an axis hole, and steel strand are placed through this axis hole in the use.This drum can be made with the high strength cross-linking plastic.Described catch and half-axile sleeve are connected as a single entity, and are single piece.

The pull bar of described messenger wire is made by metal, it can be after bending firmly lash in drum.Other parts of backguy are also declared with metal made, require to have oxidative resistance and enough intensity.Described extension presss from both sides its lower end and has inside bending section, acts on the clip electric wire.

The utility model is owing to be provided with drum, and it constitutes by left and right half wheel is chimeric mutually, can be placed in steel strand after chimeric, can divide again when needing to break off with the fingers and thumb left and right half wheel is separated; But have pull bar bending lash and be provided with the messenger wire of hanging folder clip electric wire in drum, bottom but be provided with top, hang folder and can control its opening and closing through tommy bar, so the utility model uses with easy for installation, demolition conveniently is beneficial to maintenance of track; The utility model member is less, so cost is lower; Because drum is non-tightening state with respect to steel strand, so the wavy degree of steel strand is relatively little during the electric wire upheaval, vice versa.

Below in conjunction with description of drawings embodiment of the present utility model.

Fig. 1 is that a structural representation is partly taken turns on the left side of drum;

Fig. 2 is that a structural representation is partly taken turns on the right side of drum;

Fig. 3 is left and right drum one structural representation of partly taking turns chimeric formation;

Fig. 4 is that right elevation is partly taken turns on Fig. 1 left side;

Fig. 5 is the guy structure scheme drawing.

Electric car messenger wire drum assembly set is by the drum that can be placed on steel strand with can hang the messenger wire that the lower end that is coupled to drum can press from both sides pull the wire 7 and form;

But described messenger wire has a pull bar 3 bending lash in drum, pull bar 3 bottoms are fixed with pressure ring 4, be linked with symmetrical two below the pressure ring 4 and hang folder 5, two hang in the perforation of folder bottoms and are provided with bearing pin 6, and bearing pin 6 one ends are with packing ring 8 and are provided with control and hang the tommy bar 10 of folder 5 opening and closing and sell 9 and be coupled to bearing pin 6 pivotly;

Described drum by a left side partly take turns 1 and the right side partly take turns 2 and mutually chimericly constitute, a left side partly take turns 1 and the right side partly take turns 2 and respectively have a half-axile sleeve 12 its two ends and respectively be linked with a catch, right half wheel and a left side half wheel be similar shape (rotating 180 degree according to the axle center of half-axile sleeve) in fact fully, and catch 11 1 ends of a left side half wheel are provided with protruding top 111 other ends and are provided with recess 112 and match with corresponding recess and protruding top that corresponding catch is partly taken turns on the right side respectively;

Left and right partly the wheel in the half-axile sleeve position has ledge structure, is beneficial to that the two is chimeric mutually, and the friction enhancement region that is provided with the concavo-convex flute profile of tool is beneficial to chimeric back and breaks separation off with the fingers and thumb with record book in accordion form;

Tommy bar 10 shown in Figure 5 turns to shown in the dotted line to be located, and this moment, the tommy bar face of leaning left, and two hang folder opens relatively.
