Lifting machinery macrographic examination equipment

Abstract

The invention relates to lifting machinery macrographic examination equipment. The equipment comprises an extension rod, an universal hose, a camera illuminating device, a cleaning brush and a display screen clamping device; the extension rod consists of multiple sections of coaxially sleeved sleeves; the upper end of the uppermost section of the sleeve is coaxially connected with the universal hose; the camera illuminating device is mounted at the uppermost end of the universal hose; a support rod is horizontally mounted at the upper end of the camera illuminating device; a small motor is mounted at the front end of the support rod, and is connected with the cleaning brush; and the display screen clamping device capable of rotating by an angle is mounted on the lowermost section of the sleeve. The equipment is reasonable in design, simple and convenient to assemble and light in weight, improves the personal safety of inspectors after use, reduces the inspection time, the inspection difficulty and the inspection error rate, and reduces the occurrence probability of accidents related to a crane.

Description

technical field [0001] The invention relates to the technical field of inspection and testing of special equipment, in particular to a macroscopic inspection equipment for hoisting machinery. Background technique [0002] Hoisting machinery is widely used, with a wide variety of types and a large number of areas. Every year, there are safety accidents related to hoisting machinery in various places, causing casualties and property losses. In order to strengthen the use management of hoisting machinery and reduce its failure rate and accident rate, our country has defined hoisting machinery: it is included in the catalog of special equipment, supervised and inspected by relevant units in accordance with the "Special Equipment Safety Law", and the user unit Carry out routine maintenance. In the "Lifting Machinery Inspection and Testing Rules" promulgated by the state, macro inspection accounts for a large proportion of all inspection items, and more than half of the inspectio...

AI Technical Summary

Problems solved by technology

[0005] ⑴. When inspecting the cranes in the enterprise according to the "Lifting Machinery Inspection and Testing Rules", it is dangerous to climb a crane that is more than a few meters above the ground without ladders, lifting equipment, and protection. In the case of lifting equipment, there are also unsafe factors for climbing operations, and timid people dare not go up, so some observation blind spots cannot be checked, and inspections are often not in place, which may leave hidden dangers of accidents

[0006] ⑵. In the process of checking the crane information or location, whether the certificate of conformity is consistent with the on-site machine nameplate, electric hoist nameplate, etc.; whether the product number of the on-site crane is consistent with the corresponding place of use recorded on the data; It will be reflected in the inspection report issued by the inspector. If the identified place of use is inconsistent with the actual place of use of the crane and an error occurs, this error will appear on the inspection report and will not be easy to find in subsequent inspections. The inspection report lacks correctness, authority and seriousness

[0007] The above two situations increase the working time, work difficulty and work responsibility risk for the inspectors under the reality that there are fewer special equipment inspectors and the work tasks are more and more heavy.

[0008] ⑶. During the daily maintenance of the hoisting machinery by the maintenance personnel of the hoisting machinery user unit, it is necessary to check the overall structure, such as: bridges, metal structural parts of gantry cranes, small frame structural parts, and lifting mechanisms , running mechanism and track, etc., to check whether there are cracks, corrosion, abnormal deformation, looseness, falling off, oil leakage, wear of brake pads, etc. For accessible cranes, you can board the crane for inspection. Cranes that are accessible and inaccessible under safe conditions (such as electric single-girder cranes) will be less effective in daily maintenance

When a problem occurs, it may cause a safety accident, resulting in casualties and property losses. This is related to the fact that some users do not pay attention to safety management, and it is also related to the lack of convenient inspection methods.
