Passenger car braking beam sleeve-retreating and sleeve-insetting machine

Abstract

The invention belongs to a special device used for the automatic tapering and automatic embedding of shaft sleeves at two ends of a brake beam in railway passenger car, in particular to a sleeve removing and sleeve embedding machine used for the brake beam of passenger car; the structure of the machine consists of a hydraulic station, an operation control device and an embedding removing device; the embedding removing device consists of a machine body with a supporter, a lifting transmission device, a left hydraulic cylinder and a right hydraulic cylinder, a left milling device, a right milling device and a positioning clamping device; the lifting transmission device drives the left milling device and the right milling device to ascend or descend; the left milling device and the right milling device are respectively provided with two milling heads; left end and right end of the working platform of the machine body are respectively provided with the left hydraulic cylinder and the right hydraulic cylinder; a left fixed positioner, a right fixed positioner and a group of movable push-clamps are respectively arranged between the left milling device and the right device; the machine has the advantages of strong pertinence, convenient usage, simple operation, novel structure and reliable operation.

Description

technical field [0001] The invention belongs to the special equipment for automatic withdrawing and automatic mounting of the two-end axle sleeves of the brake beam in the railway passenger car. Background technique [0002] At present, there are pin sleeves in the pin holes used to hang various auxiliary parts on the national railway passenger car bogies. When the bogie is in use after a section repair or factory repair period, the old pin sleeves must be removed. At the same time, install a new pin sleeve with a suitable size in the original pin hole. Since the size of the two end sleeves of the brake beam in the bogie is Φ55mm, the length is 65mm, and the skin thickness is 5mm, the work of retreating and inserting the sleeve is extremely troublesome. The traditional method of withdrawing and inserting the sleeve is to remove and install the old sleeve manually by smashing it with a sledgehammer or cutting it with acetylene, which will easily cause cracks in the brake beam...

Problems solved by technology

[0002] At present, there are pin sleeves in the pin holes used to hang various auxiliary parts on the national railway passenger car bogies. When the bogie is in use after a section repair or factory repair period, the old pin sleeves must be removed. At the same time, install a new pin sleeve with a suitable size in the original pin hole. Since the size of the two end sleeves of the brake beam in the bogie is Φ55mm, the length is 65mm, and the skin thickness is 5mm, the work of retreating and inserting the sleeve is extremely troublesome. The traditional method of withdrawing and inserting the sleeve is to remove and install the old sleeve manually by smashing it with a sledgehammer or cutting it with acetylene, which will easily cause cracks in the brake beam and seriously affect the driving safety. It is very troublesome for workers to operate, low work efficiency and high cost. It is very necessary to develop a new type of device for withdrawing and inserting sleeves to overcome the existing problems in the existing technology.
