Multi-cylinder driving caterpillar type low speed and heavy loading device walking mechanism

Abstract

The invention provides a multi-cylinder driving caterpillar type low speed and heavy loading device walking mechanism. The walking mechanism comprises a controlling unit, a transducer for detecting the location of the caterpillar teeth, a forward driving system which drives the caterpillar teeth and is arranged on each caterpillar frame, and a retreat driving system. The forward driving system andthe retreat driving system separately comprises two sets of travelling complementary driving device, and each set of the driving device comprises at least one driving unit; each driving unit comprises a driving head for driving the caterpillar teeth, a pressing oil cylinder controlling the driving head to move up and down, a driving cylinder controlling the driving head to move front and back todrive the caterpillar teeth, and a travelling switch for detecting the pressing oil cylinder and the location of the driving cylinder piston; the pressing oil cylinder and the driving cylinder are connected with the controlling unit by a solenoid valve, and the transducer for detecting the location of the caterpillar teeth and the travelling switch are connected to the controlling unit. The mechanism cancels the structures comprising a walking hydraulic motor, a walking speed reducer, and a driving wheel and the like, and the mechanism directly uses the cylinder to drive the caterpillar teethof a caterpillar plate to achieve the functions of walking front and back, turning, and grinding and turning and the like.

Description

technical field [0001] The invention belongs to a traveling mechanism of engineering machinery, in particular to a crawler-type low-speed heavy-duty equipment traveling mechanism driven by multiple oil cylinders, which can be applied in the crane industry. Background technique [0002] The crawler crane travel mechanism usually uses a hydraulic motor to drive a planetary reducer, and drives the crawler through a toothed drive wheel to realize functions such as front and rear walking, turning, and grinding. First, the cost is high, the cost of the motor and reducer is high; Walking under these working conditions will cause early damage to the walking reducer. It is necessary to seek a solution with relatively low cost and relatively convenient maintenance. Contents of the invention [0003] In order to solve the problems of high cost, difficult maintenance, and unsuitability for long-distance walking and walking on relatively large slopes in the crawler-type construction ...
