Abstract

The utility model discloses a simple pantograph for a cold running test of a contact network. The pantograph comprises a base, a bracket and a pantograph body arranged on the top of the bracket, wherein a diamond telescopic bracket structure is arranged on the end face of the bracket; support rods forming the bracket are correspondingly connected through shaft sleeves; the bracket is fixedly connected with the base through bolt connecting pieces; spring adjusting rods are arranged on adjacent support rods at the lower end of the diamond telescopic bracket structure; the two ends of each of at least two traction springs are movably connected with the spring adjusting rods; the base is formed by connecting two pieces of channel steel and two pieces of angle steel through bolts; and the pantograph body is connected with the top of the bracket in a welding mode. The pantograph can dynamically detect the contact network under the condition that a contact network detection vehicle is not in place.

Description

The simple and easy pantograph of the cold sliding test of contact system
Technical field
The utility model relates to a kind of railway contact line detection of dynamic instrument, the simple and easy pantograph of the cold sliding test of contact system.
Background technology
During present domestic railway contact line detection of dynamic, all be to use the Contact Line Detection car to detect, existed a lot of drawbacks since like this, the one: inspection vehicle expensive price, limited amount can not guarantee can both use on all circuits; The 2nd: preceence that can not bring into play inspection vehicle in the complicated hinge area of circuit situation.So the Contact Line Detection car generally is used in the main line of growing up, do not adopt the Contact Line Detection car such as China the Northeast.
The utility model content
The technical matters that originally will solve provides and connects the simple and easy pantograph device of the cold sliding test of a kind of net-fault, under the situation of not using the Contact Line Detection car, contact system is carried out detection of dynamic.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
The simple and easy pantograph of the cold sliding test of contact system; The pantograph that comprises base, support and setting and cantilever tip; Said bracket end face is a rhombus telescope support structure, and the each several part strut bar that constitutes said support corresponds to through axle sleeve and connects, and states support and captives joint with base through bolt connection piece; Be respectively equipped with the spring adjust bar on the adjacent strut bar in said rhombus telescope support structure lower end, the tractive both ends of the spring connects the spring adjust bar respectively.
Said base is that two channel-section steels and two angle steel form through bolted connection; Said pantograph is connected with cantilever tip through welding manner.
At least two on said tractive spring, tractive both ends of the spring and spring adjust bar flexibly connect.Utilize the characteristics of rhombus flexible type, between rhombus, add the tractive spring, make it under external force can free lifting.
Method of application:
The first step: the utility model simple and easy pantograph of cold sliding test of touching net is fixed on Operation Van's job platform.
Second step: connect the tractive spring one by one, the limit is measured bow with spring balance and is pressed, to reach the detection demand.
The 3rd goes on foot: job platform is risen to needs height.
The 4th step: the running job car, carry out detection of dynamic.
The utility model connects to satisfy fully under net-fault inspection vehicle situation not in place contact system is carried out detection of dynamic.
Description of drawings
Fig. 1, the simple and easy pantograph structural representation of the cold sliding test of the utility model contact system.
The specific embodiment
The simple and easy pantograph of the cold sliding test of the contact system of meaning as shown in Figure 1; The pantograph 3 that comprises base 1, support 2 and setting and support 2 tops; Said support 2 end faces are rhombus telescope support structure; The each several part strut bar 21 that constitutes said support 2 corresponds to through axle sleeve 22 and connects, and states support 2 and captives joint with base 1 through bolt connection piece; Be respectively equipped with spring adjust bar 24 on the adjacent strut bar 21 in said rhombus telescope support structure lower end, tractive spring 23 two ends connect spring adjust bar 24 respectively.Said base 1 is that two channel-section steels and two angle steel form through bolted connection; Said pantograph 3 is connected with support 2 tops through welding manner.23 at least two on said tractive spring, tractive spring 23 two ends and spring adjust bar 24 flexibly connect.
The above record is merely the embodiment that utilizes the utility model technology contents, and modification, variation that any people who is familiar with this technology uses the utility model to do all belong to the claim that the utility model is advocated, and be not limited to embodiment.
