Cross-arm mechanical performance test device

Abstract

The present invention proposes a cross-arm mechanical property test device, which includes a fixing frame, on which a bearing frame is horizontally and fixedly installed, and a connecting piece is arranged in the supporting frame, and one side of the connecting piece is fixedly installed with a mounting bracket for connecting the cross-arm. The first flange, the end of the bearing frame close to the first flange is fixedly installed with the second flange for connecting the cross arm, the other side of the connecting piece is horizontally connected with a lateral force applying device, the connecting piece The bottom is detachably connected with a longitudinal force applying device, and the transverse force applying device is slidably connected with the other end of the bearing frame. The present invention tests the mechanical properties of the cross-arm in a single transverse direction, a single longitudinal direction, and a transverse and longitudinal direction in a workshop, and by performing mechanical tests under multiple conditions, the mechanical properties of the cross-arm material can be evaluated by synthesizing data of multiple conditions.

Description

technical field [0001] The invention relates to the technical field of a test device for a steel pipe pole cross arm of a transmission line, in particular to a test device for the mechanical properties of a cross arm. Background technique [0002] At present, the fixed base test method is widely used in the mechanical test of steel pipe cross arm in my country, but this test method generally has the following problems: 1. The usual test process is: first select a large open space, excavate two foundations , One of the foundations is embedded with a pull plate, the other is embedded with bolts, and the embedded bolts are connected to the steel base; during the test, the pull plate is connected to the guide chain, and the steel base is connected to the test cross arm flange. This increases the production cost; 2. The two foundations are fixed and cannot be moved, resulting in low site utilization efficiency and waste of resources; 3. During the test, workers need to carry cross...

Problems solved by technology

[0005] The present invention proposes a cross-arm mechanical performance test device to solve the problem that the mechanical test device in the prior art can only cause the cross-arm to deform in the longitudinal direction, but cannot carry out transverse stress deformation, and simultaneous deformation in the transverse and heald directions, thus The problem that the mechanical test conditions are single and the mechanical properties of the cross-arm material cannot be comprehensively evaluated
