Embodiment Construction

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0020] Such as Figures 1 to 3 As shown, the coupler inner cavity steel sand cleaning machine for railway vehicles includes a frame 1, a main transmission box seat 9 and two auxiliary transmission box seats 2 installed thereon. The main transmission box 10 is installed on the main transmission box seat 9 by connecting bolts. A pair of rolling bearings 13 in the main transmission box are arranged in the box for installing the main transmission shaft 11. The input end of the main transmission shaft 11 is connected with the reduction motor 12. This axle has the output end of notch and coupler turning frame 4 to be fixed by four clamping plates 15, and every clamping plate 15 is installed on the coupler turning frame 4 ...

Abstract

The invention relates to a vehicle coupler inner-cavity steel shot cleaner for railway vehicles. The cleaner comprises a frame, a main transmission case seat arranged on the frame, at least one auxiliary transmission case seat and at least one vehicle coupler turning frame, wherein the main transmission case seat is provided with a main transmission case, a rolling bearing provided with a main transmission shaft is arranged in the main transmission case, and both ends of the main transmission shaft are connected with a reducing motor and the vehicle coupler turning frame respectively; the auxiliary transmission case seat is provided with an auxiliary transmission case, a rolling bearing provided with an auxiliary transmission shaft is arranged in the auxiliary transmission case, and the auxiliary transmission shaft is connected with the vehicle coupler turning frame; and each vehicle coupler turning frame is provided with a bolt seat which is provided with a bolt hole and a stop block, and a vehicle coupler inner cavity to be cleaned is inserted into the bolt hole to be fixed on the vehicle coupler turning frame. The vehicle coupler inner-cavity steel shot cleaner has high steel shot cleaning efficiency, so the excessive occupation of running trains is avoided; meanwhile, various working positions can be freely stopped and self-locked at any required angle, so that operators can perform steel shot cleaning operation conveniently.

Description

technical field [0001] The invention relates to a cleaning machine for railway vehicles, in particular to a steel sand cleaning machine for coupler inner chambers of railway vehicles. Background technique [0002] The coupler is an important part of the railway vehicle, which is directly related to the safe operation of the railway vehicle. With the need of high-speed and heavy-duty railway transportation, the quality requirements of the coupler are getting higher and higher. The coupler is a kind of steel casting, and its shape and inner cavity are relatively complicated. After the coupler is cast, it must be sandblasted with steel shot. steel grit. Therefore, all residual steel grit in the inner cavity of the coupler must be completely removed before entering the next flaw detection process. At present, the known technology still does not have a kind of special equipment for cleaning the steel sand in the inner cavity of the railway vehicle coupler. Some manufacturers,...
