Description

An inspection shoe with automatic angle adjustment

technical field

The invention relates to the technical field of auxiliary equipment for inspection equipment, in particular to an inspection shoe with automatic angle adjustment.

Background technique

According to the general requirements for on-site conditions in the safety technical specification for special equipment "Stationary Pressure Vessel Safety Technology Supervision Regulations", the user unit and related auxiliary units should do a good job of technical treatment after shutdown and safety inspection before inspection as required. Do relevant preparations.

When inspecting the inner surface of some super-large-volume pressure vessels and atmospheric pressure vessels, inspectors need to crawl on the wall for macroscopic inspection, thickness measurement and non-destructive testing. Often the walls of the container are curved, with a gentle slope that can be crawled on. The existing method is to set up climbing facilities such as scaffolding and portable ladders for inspection. For adopting this method, on the one hand, it is time-consuming and laborious; Scaffolding and portable ladders are not easy to support and erect. In addition, for super-large containers, wearing inspection shoes and directly crawling on the wall of the equipment while wearing a seat belt will make the inspection more convenient and efficient. We noticed that when the daily inspection shoes are used on a sloped equipment wall, since the heel and toe are not on the same level, it is difficult for the inspector to control the balance to carry out the inspection. The inspectors bring greater inspection difficulty, and the existing inspection shoes do not have the ability to self-adaptively adjust the inclination to improve the balance of the human body. In view of this, it is necessary to improve the existing inspection shoes.

Contents of the invention

In order to automatically adjust the inclination angle of inspection shoes and improve the balance of inspectors when inspecting on inclined equipment walls, the present invention provides an inspection shoe that automatically adjusts the angle, and the specific technical solution is as follows.

An inspection shoe with automatic angle adjustment, which includes a sole, a heel and a shoe body arranged on the sole, a movable plate is arranged above the sole, and an insole with the same shape and size as the movable plate is arranged above the movable plate. The plate includes a front part and a rear part which are mutually hinged, and the hinge axis of the movable plate is located at the forefoot position of the shoe for inspection, and the hinge shaft slot for accommodating the hinge axis is arranged on the sole; the shoe sole corresponds to the The position of the heel is provided with a lifting mechanism for adjusting the inclination angle of the rear portion of the movable plate; a power supply is provided in the heel, and an inclination sensor and a stepping motor are arranged in the middle of the sole, and the inclination sensor and the stepping motor A main control board is arranged above, and the stepping motor is used to drive the lifting mechanism; the inclination sensor, stepping motor, and main control board are all electrically connected to the power supply, and the main control board and the inclination sensor connected to control the stepper motor;

The lifting mechanism includes a screw rod, an upper wedge-shaped slider, a lower wedge-shaped slider and a fixed guide block. The screw rod extends along the front-to-back direction of the shoe for inspection. The screw rod is fixedly connected to the rotating shaft of the stepping motor and the two ends of the screw rod The end is rotatably supported in the sole, the screw rod passes through the screw hole of the lower wedge-shaped slider, the upper surface of the lower wedge-shaped slider and the lower surface of the upper wedge-shaped slider are wedge-fitted, and the lower surface of the upper wedge-shaped slider Rollers are also arranged on the surface, and the top of the upper wedge-shaped slider is connected with the rear part of the movable plate.
