Description
Technical field:
The present invention relates to electric transmission pole tower testing equipment field, more specifically and a kind of power of changing car be arranged in model test between electric transmission pole tower and loading force device.
Background technology:
Electric transmission pole tower is holder the most frequently used on high voltage circuit, is generally bolted by angle steel and forms.Because the material behavior of angle steel and the difference of Transmission Tower make electric transmission pole tower force analysis comparatively complicated.But the frequent generation of disaster in recent years, electric power pylon phenomenon of collapsing also happens occasionally, therefore the design and analysis of power transmission tower model test to electric transmission pole tower is also even more important.And general when carrying out power transmission tower model test, by multiple pulley and wire rope, the pulling force that hydraulic cylinder produces to be loaded on electric transmission pole tower model.The program, when loading, can run into 3 problems:
(1) when being positioned at without ground anchor bolt in the plane that electric transmission pole tower load(ing) point and hydraulic cylinder force point determine, testing crew often adopts a ground anchor bolt near vertical plane to be similar to replacement, and this can cause occurring force level angle error β.As shown in Figure 4.That is, traditional load mode cannot realize the smooth change of loading force horizontal angle.
(2) pulling force due to a hydraulic cylinder is not enough, needs the load(ing) point of multiple hydraulic cylinder with model electric transmission pole tower to be connected by wire rope.Like this, when the size of multiple lineoutofservice signal pull changes, the horizontal angle of making a concerted effort also can change.This phenomenon can cause loading personnel to be difficult to according to testing program, controlled loading force level angle.
(3) each model test has the operating mode of more than 3 usually.Adopt the mode of pulley and wire rope to test, need the arrangement frequently adjusting pulley, wire rope, waste time and energy.
In order to solve the problem, propose a kind of can comparatively laborsaving, save time, the vertical angle of adjustment loading force simple to operation, power of the changing car of horizontal angle.
Summary of the invention:
The object of this invention is to provide a kind of power transmission tower model test and change power car, this changes Li Che can in power transmission tower model test, comparatively laborsaving, to regulate loading force fast, smoothly vertical angle, horizontal angle.
For achieving the above object, the present invention is by the following technical solutions: a kind of power transmission tower model test changes power car, the described power of changing car for testing electric transmission pole tower tolerance in its model test, described in change power car comprise guide rail (1), and described guide rail (1) between power of the changing frame (2) that be arranged in parallel and with described lead rail axis to the vertically disposed power of changing rod (3).
A kind of power transmission tower model test provided by the invention changes power car, and described guide rail (1) is connected in same level by bearing (4) with power of the changing frame (2) be arranged in parallel therebetween.
A kind of power transmission tower model test provided by the invention changes power car, and guide rail described in each (1) is connected with one end of two wire rope (5 '), and the same guide rail (1) that is interconnected of the other end of described two wire rope (5 ') forms triangle; Power rod (3) is changed described in arranging between the interlinkage of the described other end.
Another preferred a kind of power transmission tower model test provided by the invention changes power car, the wire rope (5) of link model electric transmission pole tower load(ing) point along described in change power rod (3) one end radial direction through with change power frame (2) and be connected.
A preferred a kind of power transmission tower model test more provided by the invention changes power car, and described guide rail (1) is horizontally set on terrace by ground anchor bolt.
Another preferred a kind of power transmission tower model test provided by the invention changes power car, described in change power rod (3) surface and be provided with coating, described coating is lubricant.
Another preferred a kind of power transmission tower model test provided by the invention changes power car, and described lubricant is dag.
Another preferred a kind of power transmission tower model test provided by the invention changes power car, changes the other end of power frame (2) and wire rope (5) tie point described in loading force device is connected to.
Owing to have employed technique scheme, the beneficial effect that the present invention obtains is:
1, the horizontal angle that power car can regulate loading force fast, is smoothly changed in the present invention, vertical angle;
The use of 2, changing power car in the present invention decreases the installation process of the component such as pulley, wire rope;
3, the power of changing car of the present invention uses simple, and simple installation is time saving and energy saving;
4, guide rail is reduced in changing the friction force between power frame by bearing in the present invention;
5, the excellent lubricant scribbled by surface of power of changing in the present invention regulates vertical angle better.
6, the present invention change power car intensity high, from heavy and light, stable working, reliable operation, wire rope not easily whole root fracture suddenly
7, the power of changing car of the present invention the model test of electric transmission pole tower is more simplified, easy to operate.

Embodiment
Below in conjunction with embodiment, the invention will be described in further detail.
Embodiment 1:
As Figure 1-3, the use of power of the changing car of this example invention is first fixed on ground anchor bolt by two closed slides 1, by bearing 4 with change power frame 2 and be connected, be connected with one end of two wire rope 5 ' respectively at each closed slide 1, the other end of two wire rope 5 ' be interconnected same guide rail (1) and form triangle; Change power rod (3) described in arranging between the interlinkage of two other ends, make to change that power rod 3 is unsettled to be arranged between two guide rails 1.Be connected with excellent 3 one end of power of changing by wire rope 5 by the load(ing) point of model electric transmission pole tower, the vertical angle α adjusting power by changing the distance L changing power rod 3 and load(ing) point vertical projection point arrives requirement.Then, the horizontal angle of power on load(ing) point as requested, determines the vertical loaded planar by load(ing) point, is fixed in this vertical plane any point crossing with changing power frame 2 by wire rope 5 along changing power rod 3 radial direction through behind the bottom changing power rod 3.Then the other end changing power car is connected with hydraulic cylinder and carries out load test.
