Problems solved by technology

The load loading method commonly used in the simply supported type is horizontal loading. The equipment used cannot easily load the pole upwards and downwards, and the common mechanical tests of the poles are all done by separately designing the mechanical properties of the poles. The detection device is used for detection, which requires a lot of equipment, which cannot achieve the multi-purpose effect and multi-functionality of one machine, and the detection economy is insufficient; and the conventional detection method is inconvenient to install, and the safety and scientificity of the inspection cannot be guaranteed.

Embodiment 1

[0039] Embodiment 1: Simply supported horizontal loading mechanical performance detection, such as Figure 8 As shown, the two fixed boxes are placed left and right in the prefabricated foundation pit, and the third U-shaped skid 18 and the fourth U-shaped skid 21 are fixedly connected to the fourth fixed box 30 and the third fixed box 22 respectively. On the side, the second rolling bracket 19 and the third rolling bracket 20 with equal distances are placed in the middle of the two fixed boxes to eliminate the influence of the self-weight of the pole on the detection of the pole, and the equal-diameter pole is placed between two U-shaped skids. On the U-shaped groove, the second tension sensor 23 and the second loading device 24 are placed at the center of the pole, placed on the same side of the fixed box, and the two ends of the balance pole 36 are connected to both sides of the center of the pole to load the pole. , find a reference point on the vertical center plane of th...

Embodiment 2

[0040] Embodiment 2: Simply supported upward loading mechanical performance detection, such asfigure 1 , Figure 5 , Figure 6 and Figure 7 , simply supported upward loading and downward loading use the same loading equipment and supporting components, change the direction of the loading point and the force of the supporting point, fix and install the two fixed boxes 7 in the prefabricated foundation pit respectively, and fix the upper end of the box 7 Fixedly connect the U-shaped hoops, clamp the two ends of the equal-diameter electric pole through two U-shaped hoops, place the jack 9 on the disc base 4, connect the pressure sensor 10 at the upper end, and connect the U-shaped skid at the upper end of the pressure sensor 10, The U-shaped skid is placed at the center of the pole, and a reference point is found on the horizontal center plane of the pole as the zero point, and the switch button of the jack 9 is activated to push the jack 9 upward to transmit the force to the p...

Embodiment 3

[0041] Embodiment 3: Cantilever type horizontal loading mechanical performance detection, such as figure 2 and Figure 9 As shown, place the first U-shaped skid 12 on the side of the main wall panel 2, install and fix the large end of the tapered electric pole through the U-shaped groove of the second U-shaped skid 12, and place the second U-shaped pad on the other fulcrum Wood 13, the second U-shaped skid 13 is placed on the side of the second fixed box 14, and the pole is supported by the second rolling bracket 15 at a distance from the top. The bottom surface of the second rolling bracket 15 is provided with rollers. Move easily on the top of the pole to eliminate the influence of self-weight on the detection of the pole. The first tension sensor 16 is connected to the top of the pole through a wire rope, and the first tension sensor 16 is fixedly connected to the first loading device 17. Accurate a reference line, as a zero point, start the first loading device 17, allow...

Abstract

The invention provides a multifunctional concrete electric pole mechanical property detection platform. The multifunctional concrete electric pole mechanical property detection platform comprises a main body platform, a fixed box body and an L-shaped support. The main body platform comprises a base and a main wallboard, the main wallboard is fixedly connected to the base, the base is fixedly connected to the ground, the main wallboard has circumferential flange holes and long grooves which are symmetrically distributed in the horizontal direction and non-uniformly distributed in the transverse direction, the fixed box body is arranged in a foundation pit or fixed in the foundation pit, the side surface and the upper end surface of the fixed box body can be fixedly connected with U-shaped sole timber or a U-shaped hoop, and the L-shaped support is fixedly arranged behind the main wallboard. By adopting the L-shaped support, the fixed box body, the flange connecting holes and the long grooves, the test on different mechanical properties of a concrete electric pole can be realized, and the purposes of integrating the detection of various mechanical properties of the electric pole, saving time and labor and realizing high-efficient detection can be realized. The platform is simple in structure, convenient to operate, easy to assemble and high in safety and scientific performance, and important significance on promoting the healthy development of the electric pole industry can be achieved.

Description

technical field [0001] The invention belongs to an electric pole detection technology, and relates to a multifunctional concrete electric pole mechanical property detection platform. Background technique [0002] There are two types of testing methods for the mechanical properties of poles: simply supported and cantilevered. The load loading method commonly used in the simply supported type is horizontal loading, and the equipment used cannot easily load the pole upwards and downwards, and the common mechanical inspection of the pole is done by separately designing the mechanical properties of the pole. The detection device is used for detection, which requires a lot of equipment, which cannot achieve the multi-purpose effect and multi-functionality of one machine, and the detection economy is insufficient; and the conventional detection method is inconvenient to install, and the safety and scientificity of the inspection cannot be guaranteed.
