A push transfer device for a sandbox trolley

Abstract

The invention provides a push transfer device for a sandbox trolley. The push transfer device for a sandbox trolley comprises a telescopic hydraulic cylinder, a fixed base, a hydraulic cylinder piston, support pillars, a frame, a slide way, a sliding trolley, sliders and a sandbox. The lowest end of the device is provided with the frame with the slide way; the sliding trolley and the telescopic hydraulic cylinder are arranged on the frame; two sliders are arranged under the sliding trolley and can slide on the slide way; the three support pillars are arranged between the slide way and the frame; the fixed base is arranged between the telescopic hydraulic cylinder body and the slide way; the front end of the hydraulic cylinder piston of the telescopic hydraulic cylinder is provided with a slider in sliding fit with the slide way; the headmost end of the hydraulic cylinder piston is in buffer connection with the rear end of the sliding trolley. The push transfer device for a sandbox trolley is simple in structure, good in buffer effect and high in push transfer precision, can effectively prevent pollution to a cooling section, facilitates cleaning and effectively reduces the labor intensity of workers.

Description

technical field [0001] The invention relates to the field of casting production devices, and in particular provides a pushing device for a sand box trolley. Background technique [0002] At present, the transmission of the sandbox trolley is mainly carried by a transfer vehicle. A separate oil cylinder is installed on each cooling section. After the sandbox trolley is placed on the transfer vehicle, the oil cylinder pushes the transfer vehicle to move on the cooling section to complete the sanding The transmission of box trolleys, but there is a problem with the transmission of oil cylinders in this way, that is, the oil cylinders often leak oil, which will pollute the cooling section by oil leakage, and the working site environment of the cooling section will become dirty Unbearable, workers need to clean up frequently, resulting in super labor intensity for employees. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned...
