Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering, and particularly relates to a supporting device for an extension rod of a pipeline detection probe. Background Art

[0002] During the process of inspecting the inside of a steel pipe, it is often necessary to send a probe into the pipe for inspection, such as checking for wear and corrosion on the inner wall of the pipe. The length of the steel pipe is often very long, so an extension rod is needed to support the probe to ensure that the probe can reach the far end of the steel pipe smoothly. However, due to its excessive length, the extension rod is prone to bending, which not only affects the positioning accuracy of the probe but may also cause damage to the probe, thereby affecting the reliability and accuracy of the inspection results.

[0003] In traditional technologies, usually additional support points are added or more rigid materials are used to make the extension rod. However, these methods often increase the complexity and cost of the system, and may not be applicable to extremely long or frequently moving inspection environments.

The bottom of the base is symmetrically provided with first universal self-locking wheels, and the top of the base is symmetrically provided with hydraulic cylinders. The top of the bearing plate is connected to the inner bottom of the sliding sleeve through a rubber block, and traction plates are symmetrically arranged on the outer side of the sliding sleeve. A moving block is arranged on the top of the sliding sleeve. The first lead screw and the second lead screw are connected through a belt drive structure, and one end of the first lead screw is connected to the output end of the motor. The bump is connected to the first lead screw and the second lead screw. The top of the moving block is provided with a first detection frame and a second detection frame. Chinese Patent with Application No. 202311592731.5 discloses a support device and method for pipeline detection equipment. The disclosed support device includes a support table. A moving mechanism is fixedly installed on the left side of the upper surface of the support table. The right end of the moving mechanism is fixedly installed with a detection installation mechanism.

A fixed abutting mechanism is fixedly installed on the upper surface of the support table in front of the movable abutting mechanism.

[0005] In the above-mentioned disclosed prior art, the detection range of the device is increased by connecting and extending the lead screw. During the detection process, when the detection device needs to be frequently moved, the extended lead screw is likely to bend and deform, which in turn causes the detection device to shake, resulting in errors in the detection results. In some cases, the detection device may even collide with the inner wall of the pipeline during the shaking process, causing damage to the detection device. Summary of the Invention

[0025] Furthermore, the base 1 provides a stable support and installation platform for the entire device. The support mechanism 4, the adjustment mechanism 3, and the limit component 2 are all installed on the base 1. Specifically, the support mechanism 4 is connected to the bottom of the base 1, and the limit component 2 is arranged on the upper side of the base 1. The movement position of the limit component 2 is controlled by the adjustment mechanism 3. When the support arm 401 is lifted upward under the action of the cylinder 5, the limiting member 202 of the limit component 2 limits the support arm 401, thereby realizing precise positioning of the support height of the support arm 401, and further ensuring the support effect on extension rods of different heights.

[0026] The support arm 401 is arranged along the length direction of the base 1, and the support arm 401 is located in the movement direction of the limit component 2.
