Embodiment 1

[0029] In the present invention, the structure of the overcoat scaffold base that can monitor the stress state of the chassis is as follows: Figure 1-2 , the implementation principle structure of the present invention is as follows image 3 .

[0030] like Figure 1-2 As shown, the jacketed scaffold base capable of monitoring the stressed state of the chassis includes jacketed steel pipe 1, steel plate chassis 2, resistance strain gauges 3-6 of strain sensors integrated on the steel plate chassis 2, and external wireless intelligent strain monitoring equipment.

[0031] like image 3 As shown, the wireless intelligent strain monitoring device includes a signal input interface, a signal conditioner, an A / D converter, a microcontroller and a wireless transmission device. The output of the strain sensor is connected to the signal input interface, the output of the signal conditioner is connected to the input of the A / D converter, the output of the A / D converter is connected t...

Embodiment 2

[0038] like Figure 1-3 As shown, the structural setting and application principle of an overcoat scaffold base capable of monitoring the stress state of the chassis of the present invention are the same as those in Embodiment 1. The strain sensor is a resistance strain sensor, and a bridge circuit is used as the measuring circuit. The bridge circuit adopts a quarter bridge working mode, including four identical quarter bridge circuits, each quarter bridge circuit includes a resistance strain gauge, and the four resistance strain gauges 3-6 are uniform distributed, integrated on the steel plate chassis 2. When working, each resistance strain gauge is connected to a quarter bridge circuit, so as to measure the force variation of the steel plate chassis 2 in different directions.

Embodiment 3

[0040] like Figure 1-3 As shown, the structural setting and application principle of an overcoat scaffold base capable of monitoring the stress state of the chassis of the present invention are the same as those in Embodiment 1. The strain sensor is a resistance strain sensor, and a bridge circuit is used as the measuring circuit. The bridge circuit adopts a full bridge working mode and includes a full bridge circuit. The full-bridge circuit includes four identical resistance strain gauges 3-6, which are evenly distributed and integrated on the steel plate chassis 2. When working, the opposite strain gauges are connected to the adjacent two arms of the bridge, so that the four measured signals are connected into two differential symmetrical full-bridge working forms. Since the relative strain gauges are under the opposite force, when the strain gauges are deformed due to the force, the bridge loses balance, thereby generating a differential signal, which is connected to the ...

Abstract

The invention relates to the technical field of scaffold bases, in particular to a coat-type scaffold base, and discloses a coat-type scaffold base capable of monitoring the stress state of a chassis.The coat-type scaffold base capable of monitoring the stress state of the chassis comprises a steel plate chassis and a coat steel pipe, and also comprises a strain sensor which is integrated in thesteel plate chassis, and an external wireless intelligent strain monitoring device. The strain sensor is a resistance strain sensor, a bridge circuit is adopted to be a measuring circuit, and the working mode of the bridge circuit can be one-fourth bridge, a half-bridge, or a full-bridge. Information which is collected by the strain sensor is input to the wireless intelligent strain monitoring device by a signal input interface, after a signal conditioning and an A / D transition, the information is subjected to an analysis processing by a microcontroller, a real-time data and a piece of alarm information are sent to a PC controlling end by a wireless transmission device, so that a real-time monitoring of the variation of stresses of the scaffold base and chassis is achieved. According to the coat-type scaffold base capable of monitoring the stress state of a chassis, the potential safety hazard of the scaffold during the installation and construction using can be discovered in time, andthe security monitoring to the scaffold is maximally convenient.
