Description

Technical Field

[0001] The utility model relates to the technical field of car inspection equipment, in particular to a mobile standardized car inspection training and evaluation device. Background Technique

[0002] With the continuous progress of China's railway level and the continuous development of composite material technology, wear-resistant brake shoes have been widely used. However, during the operation of the vehicle, a large number of metal particles are generated due to the rolling action of the wheels and accumulate on the brake shoes during braking, resulting in the problem of brake shoe slag, which will affect the operation of the train and pose potential safety hazards. Therefore, it is necessary to conduct manual inspections on the braking part of the train. As a tool that must be carried during inspection operations, the car inspection hammer is widely used in the front line of railway operation production. However, the existing railway car inspection hammers have relatively single functions and can only complete knocking and touching operations.

[0003] To solve the above problems, the utility model patent with the authorization announcement number CN209553209U discloses a new type of railway car inspection hammer. This device adds a crowbar function, which is convenient for prying the brake beam. When the brake shoe slag problem is serious and the brake shoes need to be replaced, the replacement operation can be carried out immediately without going back and forth, saving the time for fetching tools, improving work efficiency, avoiding potential dangers that may exist when passing through the railway operation site, reducing the incidence of personal injury accidents, and the hammer head part is increased with an arc section, which is convenient for hooking and pulling rod-shaped, tubular and other parts, reducing the depth of the operator's body entering the vehicle structure. Due to the arc bending, it can prevent the parts from easily detaching from the hammer head, and the cross-section of the arc section gradually decreases to form a bent tip shape, which is more conducive to completing the touching operation.

[0004] During the car inspection training of the vehicle, the above-mentioned car inspection hammer is usually used for standardized maintenance operation training. Maintenance personnel need to use the car inspection hammer to knock and practice on each standardized inspection point of the vehicle. During the evaluation, since the above-mentioned car inspection hammer cannot record which specific inspection points the maintenance personnel have knocked, it is often necessary for a special person to follow and record, which is used as the basis for the final evaluation result. The recording process is relatively inconvenient; in addition, when the above-mentioned maintenance hammer is specifically used, the length of the hammer handle cannot be adjusted, which is not convenient for use in different occasions and reduces the practicability of the device.
