A mechanical braking system for a rake-suction trolley cart

Abstract

The invention relates to the technical field of trailing suction carriers and discloses a mechanical braking system of a main carrier body of a trailing suction carrier. The mechanical braking systemcomprises a carrier frame and further comprises a driving wheel, a driving mechanism, a first fixing plate, a second fixing plate and a driven wheel which are sequentially and fixedly mounted at the bottom of the carrier frame from left to right. According to the mechanical braking system of the main carrier body of the trailing suction carrier, by arranging a limiting sleeve on a second connecting plate, rotation of a first rotating rod can be converted into moving through a first movable sleeve, meanwhile, rotation of second rotating rods is converted into moving through second movable sleeves while the first rotating rod enables the second rotating rods to rotate through a first gear and second gears, the main carrier body is braked through friction force between a friction block and asteel rail while a first connecting plate and the second connecting plate are closed, force bearing of the surface of the friction block is uniform through cooperative use of the second rotating rodsand the second movable sleeves, the contact area between the friction block and the steel rail is increased, and the braking effect of the mechanical braking system is improved.

Description

technical field [0001] The invention relates to the technical field of raking and suction trolleys, in particular to a mechanical braking system for a raking and suction trolley cart. Background technique [0002] The rake suction trolley is composed of a cart (main cart) and a horizontal working trolley on it, a control system and a power supply system. The cart is composed of a frame, a control room, a driving mechanism, a horizontal guide wheel mechanism, a braking system, The speed measurement electronic control system is composed of the existing part of the braking system of the cart. The contact between the friction block and the rail is realized by rotating the friction block, and the brake is performed by friction force. Due to the rotation of the friction block, the surface of the friction block is stressed. Insufficient uniformity leads to insufficient braking effect of the device, and the structure of the connecting member of the braking device is relatively compl...
