As shown in fig. 1, the invention provides a multifunctional measuring tool for an electric power pipeline, which can measure straight pipes and bent pipes of the electric power pipeline through a cylindrical head 401, an adapter sleeve 403 and a pusher 6, and has wide application range and wider functions, and can perform not only measuring operation but also straightening operation, so that the equipment can perform propelling operation at the bent part, and the measuring head is prevented from being clamped at the bent part.

As shown in fig. 1 and fig. 3, the measuring tool includes a soft rubber column 1 (the soft rubber column 1 can select soft materials such as rubber, etc., so as to bend along with the pipeline), a measuring head 2 is arranged at one end of the soft rubber column 1, a display 3 is connected to the other end of the soft rubber column 1, a stretching mechanism 4 is installed between the measuring head 2 and the soft rubber column 1, a position correction cavity 5 is arranged at the central position of the soft rubber column 1, a plurality of measuring air cavities 509 are arranged outside the position correction cavity 5, and a transition cavity 510 is arranged outside the measuring air cavities 509.

When the tool is used, one end of a soft rubber column 1 provided with a measuring head 2 can be directly inserted into an electric power tube (the electric power tube is a buried pipeline) so that the measuring head 2 measures the inner wall of the pipeline to obtain the deformation of the inner wall (the measuring method at the position is to convert the depth of the measured deformation position into the compression amount of measured gas, the reaction is sensitive and rapid during measurement, the data is more accurate and visual, and the final data display can be directly observed on a display 3).

As shown in fig. 1, the extending and folding mechanism 4 includes a cylinder head 401 connected to a side wall of the gauge head 2 and an extending column 402 installed on a side wall of the soft rubber column 1 and communicated with a transition cavity 510, an adapter sleeve 403 connected to the soft rubber column 1 is sleeved outside the cylinder head 401, a slide groove 404 for limiting the adapter sleeve 403 is opened on the side wall of the cylinder head 401, a plurality of extension sleeves 405 for communicating the gauge gas cavity 509 with the cylinder head 401 are installed on an inner wall of the adapter sleeve 403, a corner sleeve 406 connected to the gauge head 2 is installed on an outer side wall of the cylinder head 401, a piston head 407 is connected to an inner wall of one end of the extending column 402, a pusher 6 for pushing the piston head 407 to move toward the gauge head 2 is connected to an inner wall of the other end of the extending column 402, and a corner bar 7 is installed between the piston head 407 and.

This mechanism 4 of stretching over can make measuring head 2 measure the straight tube and the return bend department of pipeline, and its application scope is wider, and the function is more extensive, still can carry out the operation of proofreading and correct to the measuring head 2 of card in return bend department simultaneously, and still can promote measuring head 2 further deepening pipeline after proofreading.

When the measuring head 2 moves to the bend of the pipe, the measuring head 2 is gradually pressed by the inner wall of the bent pipe, so as to move along the inner wall of the pipe, at this time, the movable measuring head 2 drives the cylindrical head 401 to slightly deflect and incline together, so that the adapter sleeve 403 slides in the slide slot 404 (i.e. the measuring head 2 can move along the track of the inner wall of the bent pipe), then the inclined measuring head 2 pushes the corner strip 7 through the corner sleeve 406, the pushed corner strip 7 pushes the piston head 407, so that the piston head moves along the extended column 402, and the movable piston head 407 can extrude the gas in the extended column 402 and the transition cavity 510 (as shown in fig. 1 and 5, the extended column 402 is in a T-shaped structure, the pusher 6 in the extended column 402 is blocked, so that the gas between the piston head 407 and the pusher 6 cannot move), then, the gas in the extended column 402 can be compressed, so that a user can observe the bending degree of the pipe through the display 3, (the larger the bending amount, the larger the amount of gas compressed, and the number of transition chambers 510 are provided, taking fig. 1 as an example, so when the pipeline deflects towards the front, and the gauge head 2 measures, the amount of gas compression in the front of the transition chambers 510 is large, because the inside of the measurement chamber 303 is provided with the observation tubes 305 communicating with the transition chambers 510 (the side wall of the observation tube 305 can be provided with scales, and meanwhile, a plurality of movable pieces can be installed inside the observation tubes 305), the movable pieces in the observation tubes 305 are combined to be in an inclined state, and incline towards the front when inclined, and tilt at the back (if the deflection direction of the bent tube is opposite, the inclined state is also opposite)), so that the bending amount of the bending degree of the pipeline can be measured, and if the bending inner wall of the pipeline has no deformation state, the movable pieces in the observation tubes 305 cannot be further inclined.

Then continuously promote the soft rubber column 1, the gauge head 2 can reset gradually at this moment, and the movable plate state in a plurality of observation pipe 305 can reset gradually, later once gauge head 2 is blocked by the deformation department of pipeline bending department, thereby gauge head 2 can be promoted by the deformation department and the tilt state appears, (promptly if the movable plate in a plurality of observation pipe 305 can further incline), gauge head 2 just can not continue the return bend slip this moment, afterwards, the user can pour into gas into in the transition chamber 510, and can get into gas in the post 402 of stretching out this moment to promote impeller 6 and move in stretching out post 402, so as to play the operation of correcting gauge head 2.

When the measuring head 2 passes through the elbow and moves to the straight pipe region again, the soft rubber column 1 can be pushed, so that the measuring head 2 enters deeper, and the inner wall of the pipeline deeper can be measured.

This measuring tool function is more, can measure the operation with the return bend region directly perceived to the pipeline simultaneously, and at the in-process of operation, if blocked in return bend department, can carry out automatic re-setting's operation to make the instrument can normally take out and can not cause the damage to the pipeline.
