Automatic power booster of slab railcar

Abstract

The invention relates to an automatic power booster of a slab railcar, belonging to photographing auxiliary tools commonly used in movies and televisions. The automatic power booster is characterized by comprising an electric control box, a fixed splint, a motor fixing chassis, a power wheel, a motor and a railway guide wheel, wherein the motor is arranged on the motor fixing chassis; the power wheel is connected to a motor shaft and embedded into a wheel groove of the motor fixing chassis; the electric control box has the functions of speed regulation, braking and direction selection; a movable adjusting plate is arranged on the motor fixing chassis, wherein one end of the movable adjusting plate is connected with a rotating chassis and the motor fixing classis through a rotating chassisfixing screw rod, and the other end of the movable adjusting plate is connected with the fixed splint through a rotating bearing. The automatic power booster adopts electric power as the driving force of auxiliary tools and simulates a driving operation mode of a motor vehicle, and a photographer who sits on the vehicle can control the operation direction, the speed, the braking, and other functions with feet, therefore, the automatic power booster slide stably and freely on various railways.

Description

【Technical field】 [0001] The invention relates to an automatic booster for a flat rail car, which belongs to the commonly used shooting auxiliary tools for film and television. 【Background technique】 [0002] The flat track car is one of the most common auxiliary shooting tools in the film and television industry. It is laid on the track and slides, and carries the cameraman to shoot along the track laid in advance. The "track" uses two hollow round tubes with a diameter of about 32mm. Any length, any shape, and any material can be used as the track. It is convenient to obtain materials and low in cost. Two people are required to operate the flat rail car, one of them is a cameraman and an assistant worker. Before shooting, the track must be laid on the ground level, and the flat rail car is erected on the track. The cameraman carries the camera and rides on the flat rail car. The auxiliary personnel push the flatbed truck to slide along the track, and the cameraman can sho...

AI Technical Summary

Problems solved by technology

There are two major difficulties in the operation of the flat rail car. The first is that the movement of the trolley is completely controlled by the assistant worker. The direction, speed and parking of the trolley are all operated by the assistant worker who has nothing to do with the lens. The cameraman wants to change the movement status during shooting , it is difficult to convey the information to the assistants, the cameraman and the assistants need a long-term running-in, and it is difficult to reach a tacit understanding; second, when using a curved track, manual pushing is easy to produce jitter, causing the shooting picture to shake, and the cameraman’s creation is in a certain range. restricted to a certain extent
