Embodiment Construction

[0014] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 As shown, the present invention mainly includes: a main body frame 1, a transmission mechanism 2, a power supply device 3 for electric rollers when multiple motors move around, a motor-embedded electric roller assembly 4, and a sensor 5. The connection method is: in the body frame 1. The two sides are respectively connected with the inner and outer fixing plates of the transmission mechanism 2 by screws through the upper and lower fixing brackets. Two groups of 12 motor-embedded electric rollers 4. The mandrels are threaded and distributed on the chain plates of the transmission mechanism 2 on both sides. The energization method of these 12 motors adopts the multi-motor circling movement wire avoiding device 3, and the energization device 3 is fixed on the bottom of the inner and outer fixing plates of the transmission mechanism 2 on both sides of the body with screws, and the sensor 5 is fixed on the bo...

Abstract

The shifter of detection robot for bearing pipe of heat exchanger includes main frame, transmission mechanism, power unit for electric rollers, motor embedding electric roller assembly and sensor. The two sides of the main frame is connected to the inner and outer fixing boards of the transmission mechanism via upper and lower fixing supports. Electrical rollers with 12 motors in two groups have their spindles distributed on the chain boards on the two sides of the transmission mechanism, and the 12 motors are powered via multi-motor circular motion device fixed to the bottom of the fixing boards. The sensor is fixed to the bottom of the main frame and opposite to the electric rollers. The present invention can shift on the finned bearing pipe of heat exchanger in both X and Y directions continuously and smoothly.

Description

technical field [0001] The invention relates to a mobile device for a robot, in particular to a mobile device for a heat exchanger pressure-bearing pipeline inspection robot, which belongs to the field of robots. Background technique [0002] The pressure-bearing pipe is a key component in the boiler heat exchanger of a thermal power plant. Its distribution is three-dimensionally arranged in multiple layers, with a depth of 1.5 meters. It is U-shaped in the plane and distributed back and forth. The distance from the fins is 12.5mm, the depth of the fins is 17.5mm, the minimum distance between horizontally adjacent pipes is 48.5mm, and the minimum distance between the upper and lower layers of pipes is 28mm. The complex pipe shape, spatial arrangement and narrow pipe spacing make it difficult for testing instruments to penetrate into the gaps of the inner pipe, which brings certain difficulties to the detection of defects on the outer surface of the inner pipe. In the curren...
