Large-scale electric drive mine car wet-type multi-disc brake sealing detection device and use method thereof

Abstract

The invention discloses a large-scale electric drive mine car wet-type multi-disc brake sealing detection device, which comprises a base, a first reference seat and a second reference seat, and is characterized in that the first reference seat and the second reference seat are fixed at the upper portion of the base, an electric push rod support seat and a rolling guide rail are fixed to the upper portion of the first reference base, a motor is installed on the electric push rod support seat and connected with a power motor bracket through a propelling mechanism, the power motor bracket is slidably mounted on the rolling guide rail, a power motor connecting seat is fixed to the upper portion of the power motor bracket, the power motor is fixed to the power motor connecting seat, a driving shaft is connected between the power motor and a connecting disc, and a brake mounting support seat and a follow-up retaining device are fixed at the upper portion of the second reference seat. The invention further discloses a use method of the large-scale electric drive mine car wet-type multi-disc brake sealing detection device. When various performances of the wet-type multi-disc brake are detected by using the wet-type multi-disc brake performance detection device, the detection efficiency can be improved while the problem of detection of the sealing performance is solved.

Description

technical field [0001] The invention belongs to the detection technology of a large-scale electric transmission mine car, and in particular relates to a sealing detection device and a use method of a wet multi-disc brake of a large electric transmission mine car. Background technique [0002] The wet multi-disc brake is an important part of the braking system of the electric drive mining vehicle. It must have good sealing performance and sufficient strength. The friction plate group of the wet multi-disc brake will generate a lot of heat during use. The heat generated by the medium will be brought to the external radiator, and the radiator and other devices will be used to cool down. It is required that the cooling cavity of the wet multi-disc brake should remain sealed when the brake friction plate group rotates. [0003] However, the wet multi-disc brake is bulky and heavy, resulting in a very large static friction force of the friction disc group. Manual detection is diff...

AI Technical Summary

Problems solved by technology

[0003] However, the wet multi-disc brake is bulky and heavy, resulting in a very large static friction force of the friction disc group. Manual detection is difficult to overcome the above difficulties, making it impossible to judge whether the wet multi-disc brake meets the technical requirements. The reliability of the operation of vehicle products also brings a lot of manpower and material losses
