Description

The draw bar stripping attachment

Technical field

The utility model relates in particular to a kind of draw bar stripping attachment that can dismantle the electric locomotive traction bar at small space under the car relevant for a kind of technological equipment of electric locomotive maintenance.

Background technology

Draw bar is the critical piece that connects electric locomotive car body and bogie, plays a part the tractive force of motor is directly passed to vehicle body.

Before 2000, the connected mode between electric locomotive traction bar and car body, the bogie is by rubber arthrosis mostly, adopts bolt directly to connect; Adopt this connected mode, need not equip by other when the dismounting draw bar, directly demounting bolt can be finished the dismantlement work of draw bar.But along with the introduction of external advanced locomotive manufacturing technology, the essence variation has taken place in the connected mode of draw bar and car body; At first traction seat 9 connects by bolt with car body, then press-fit between traction seat 9 and the draw bar 8 by the taper guide 91 that stands upside down, draw bar 8 and traction seat 9 press-fit with rubber sleeve 7 respectively and connect, utilize interference fit to connect, rubber sleeve 7 is to guarantee that the flexible connection mechanism (as shown in Figure 1) of less rotation takes place for draw bar 8 and traction seat 9.This structure has following characteristics: 1) under locomotive collision situation, whole bogie can bear the 3g horizontal acceleration, and can not produce distortion or damage; 2) angle of draw bar can guarantee the principle of low level traction, and drawbar height is lower than the center of wheel shaft, and therefore the heavy transfer amount of axle is little, and the adhesion weight utilization rate is big; 3) this apparatus structure is simple, compact, rubber sleeve 7 by draw bar 8 two ends adapts to by a small margin the gyration of bogie with respect to car body, in case reach hard-over, 8 of draw bars help suppressing the motion of shaking the head of bogie, have guaranteed the dynamic performance of bogie.

But this structure has caused the certain difficulty in the draw bar dismounting, when draw bar goes wrong the needs dismounting, how to be implemented under the locomotive and draw bar not disassembled a realistic problem when just having become locomotive maintenance in the small space from traction seat by other special equipments.

The utility model content

The purpose of this utility model is to provide a kind of draw bar stripping attachment, this draw bar stripping attachment compact volume and convenience, and light and flexible, it is little to take up room, and can dismantle draw bar in small space under the car.

The purpose of this utility model is achieved in that a kind of draw bar stripping attachment comprises:

In a better embodiment of the present utility model, described bearing is the concave shaped structure, this bearing is fixedlyed connected with two risers by a base plate and is constituted, and described two risers upper end is respectively equipped with a pin-and-hole, and described keeper is made of the alignment pin that is arranged in the described pin-and-hole; Described base plate is provided with an open-work, base plate lower surface and the concentric nut that is fixed with of described open-work.

In a better embodiment of the present utility model, be respectively equipped with a gusset between the both sides of described nut and the base plate lower surface.

In a better embodiment of the present utility model, described baffle plate is provided with a breach, and corresponding described two risers in these breach both sides are respectively equipped with a perforation that supplies riser to wear.

In a better embodiment of the present utility model, described thrustor comprises a screw rod, and this screw rod spiral shell is located in the described nut, and described screw rod lower end is provided with a rotary handle.

In a better embodiment of the present utility model, described screw rod upper end is passed by described open-work, and the upper end of this screw rod is fixed with a jacking block.

From the above mentioned, draw bar stripping attachment of the present utility model is simple in structure, easy to use, and it is little to take up room, and can by other special equipments draw bar not disassembled from traction seat in small space under the car.

Description of drawings

The following drawings only is intended to the utility model done and schematically illustrates and explain, does not limit scope of the present utility model.Wherein,

Fig. 1: the syndeton schematic diagram of draw bar and traction seat.

The specific embodiment

Understand for technical characterictic of the present utility model, purpose and effect being had more clearly, now contrast the description of drawings specific embodiment of the present utility model.Wherein, identical parts adopt identical label.

As shown in Figure 2, a kind of draw bar stripping attachment comprises a bearing 1; Described bearing 1 is the concave shaped structure, and this bearing 1 is fixedlyed connected with two risers 12 by a base plate 11 and constituted, and described two risers 12 upper ends are respectively equipped with a pin-and-hole 121; One baffle plate 2, described baffle plate 2 is provided with a breach 21, and corresponding described two risers 12 in these breach 21 both sides are respectively equipped with a perforation 22 that supplies riser 12 to wear, and described baffle plate 2 is sheathed on the riser 12 on bearing 1 top; The pin-and-hole 121 of described riser is provided with the alignment pin 4 that prevents that described baffle plate breaks away from from bearing 1 upper end; One thrustor 3 is located at the relative bearing 1 of bearing 1 bottom and energy and is moved up and down;

In the present embodiment, described base plate 11 is provided with an open-work 111, base plate 11 lower surfaces and the described open-work 111 concentric nuts 13 that are fixed with; Described thrustor 3 comprises a screw rod 31, and these screw rod 31 spiral shells are located in the described nut 13, and described screw rod 31 lower ends are provided with a rotary handle 32.

Further, as shown in Figure 2, be respectively equipped with a gusset 14 between the both sides of described nut 13 and the base plate lower surface; Described screw rod 31 upper ends are passed by described open-work 111, and the upper end of this screw rod 31 is fixed with a jacking block 33.

Below in conjunction with shown in Figure 3, the using method of this draw bar stripping attachment is made an explanation:

As shown in Figure 3, when needs dismountings draw bar, at first the radially position of the taper guide 91 of the breach 21 corresponding traction seats 9 of plate washer 2 is inserted in, and the perforation on the plate washer 2 22 is corresponding with the perforate (not shown)s of reservations in the rubber sleeve 7; Two risers 12 of bearing 1 downside by draw bar 8 is upwards penetrated in the described perforate, and described two risers 12 wear described alignment pin 4 after passing perforate and penetrating corresponding perforation 22 on the pin-and-hole 121 of riser 12; Rotary handle 32 rises screw rod 31 then, when the jacking block on the screw rod 31 33 when handstand taper guide 91 bottoms on the traction seat 9 contact, the effect of baffle plate 2 and alignment pin 4 holding capacity, form one with draw bar 8, realization passes to power the purpose of traction seat 9, continue rotary handle 32, traction seat 9 and draw bar 8 are broken away from.

In the utility model, adopting alignment pin 4 purpose of connecting is in order to be convenient to lay baffle plate 2 when working; Thrustor 3 and bearing 1 are connected by screw thread in the utility model, and rotation realizes oscilaltion, reach to support and the effect that unloads on the top.

In the present embodiment, as shown in Figure 3, also can be connected with two alignment pins 4 by a spring leaf 5, so that when dismounting finishes, take off alignment pin 4, in time spent not at ordinary times, help the keeping of alignment pin 4 in addition.

The above only is the schematic specific embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, equivalent variations of having done under the prerequisite that does not break away from design of the present utility model and principle and modification all should belong to the scope that the utility model is protected.
