Embodiment Construction

[0023] The present invention will be further described below in conjunction with the drawings and embodiments.

[0024] in figure 2 The embodiment is a schematic diagram of simulating a situation where an angle steel member is loaded under compression. figure 2 The hydraulic press, sensor, ball head and ball head seat shown are on the same plumb line, Figure 5 It is the structural drawing of the bottom ball seat. Install the two ends of the angle steel member to be tested to Figure 3 and Figure 4 The top clamp and bottom clamp are shown.

[0025] The specific description in combination with the reference numerals has been described in detail in the content of the invention, and will not be repeated here. When installing, rotate the top screw rod and the bottom screw rod to make the top pressure block and the bottom pressure block press and fix the two ends of the angle steel. The axial compression and eccentric compression of the angle steel member are realized by adjusting th...

Abstract

The invention provides a restriction device. The restriction device is used for solving the restriction problem of various section angle irons on one hand, wherein, the problem is mainly solved by clamping devices at the two ends of the restriction device, wherein, a pressed compact is a movable part, and the shape of the pressed compact can be determined according to the section shape of the component; on the other hand, the restriction device can solve the problem that the existing load unit for compression bearing test of components can not realize compression of various section angle irons or simulation of restriction of various end parts, thus realizing the aim that the load unit has simple structure, clear transferring force, accurate load application and convenient assembly and disassembly of components.

Description

Technical field [0001] The invention relates to a loading device for realizing the pressure bearing capacity test of an angle steel member, in particular to realizing the pressure test loading of the angle steel member of a transmission tower, and belongs to the field of transmission line tower design and research. Background technique [0002] At present, most of the transmission towers are designed with angle steel. The loading device for the bearing capacity test of the compression member of the transmission tower is basically composed of three parts: the loader, the test bearing frame, and the restraint device. The restraint device is used to simulate the actual restraint conditions of the test component, and the loading device is used to realize the force and deformation of the component under specific restraint conditions. Generally, the loading device is suitable for components with closed cross-section (circular, rectangular, etc.), and it is not easy to load the compress...
