Embodiment Construction

[0018] see Figure 1 to Figure 6 , There is a ball screw nut 2 on the ball screw 1. The rear wheel support seat 3 is fixed on the ball screw nut 2. One end of three push rods 4 is all fixed on the rear wheel support seat 3, and the other end is connected with the rear wheel support 24, and this end of push rod 4 can slide on the rear wheel support 24.

[0019] Worm wheel 15 is engaged with worm screw 8, and front wheel support 16 and belt pulley I14 are respectively housed on worm wheel 15; The other end of front wheel support 16 is equipped with belt wheel II18 and front wheel 19; Belt wheel I14 is fixedly connected with worm wheel 15, The pulley II18 is fixedly connected with the front wheel 19; such mechanisms share the same three groups.

[0020] The stepping motor I21 drives the ball screw 1 to rotate through the coupling I5. By controlling the number of pulses of the stepping motor I21, the linear movement distance of the ball screw nut 2 can be indirectly controlled,...

Abstract

The invention relates to a pipeline robot for internal diameter measurement. The pipeline robot for the internal diameter measurement comprises a supporting mechanism, a main driving mechanism and a laser measurement mechanism, wherein the supporting mechanism mainly consists of a nut for a ball screw, a step motor I, wheels, a connection rod, a push rod and the like; the main driving mechanism mainly consists of a worm gear, a worm rod, a belt wheel, a transmission belt and the like; and the linear movement of the pipeline robot can be realized through the driving of a step motor II. The laser measurement mechanism is mainly composed of a sensing measuring head, a sensor bracket and a step motor III. The pipeline robot provided by the invention can be used for measuring an internal diameter of a long pipeline, and can particularly meet the measurement requirement of thin and long pipes with the larger range of the internal diameter. The pipeline robot provided by the invention not only can be used for carrying out non-contact measurement on the internal diameters of the pipelines with different sizes but also can realize various measurements by means of replacing a measurement head of a sensor, such as flaw detection and the like. The pipeline robot has the advantages of high measurement precision and convenience in use.

Description

technical field [0001] The invention relates to an inner diameter measuring pipeline robot Background technique [0002] Most of the inner diameter measuring devices in the prior art are of the contact type, that is, the measurement is performed manually by means of an inner diameter micrometer. This inner diameter measuring instrument can only measure the size of the inner diameter of the circular hole, and due to the wear and tear of the measuring tool and human factors, the measurement error is relatively large. In addition, the existing inner diameter measuring instrument cannot detect the roundness and concentricity of the round hole. When the roundness of the round hole is insufficient or the concentricity error is large, the vibration amplitude of the machine is large, which affects the overall performance of the machine. It is easy to wear and the service life of the machine is short, which cannot meet the fast and accurate measurement of the inner diameter of the p...
