Embodiment Construction

[0026] The technical solutions of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0027] Such as figure 1 with figure 2 As shown, a drive system and control method of a scraper conveyor includes a head sprocket 11A, a tail sprocket 11B, a head sprocket drive mechanism, and a tail sprocket drive mechanism, wherein the head chain The wheel drive mechanism is hydraulic motor one 9A, and the tail sprocket drive mechanism is hydraulic motor two 9B; the hydraulic system driving hydraulic motor one and the hydraulic system driving hydraulic motor two include the same hydraulic components.

[0028] Now take the hydraulic system that drives the hydraulic motor 1 as an example, including three-position four-way electromagnetic directional valve 2, two-position two-way electromagnetic directional valve 3, two-position three-way electromagnetic directional valve 6, accumulator 8 and oil supplement Valve group 13, the oil inl...

Abstract

The invention discloses a driving system of a scraper conveyor and a control method. The driving system comprises a machine head chain wheel, a machine tail chain wheel, a machine head chain wheel driving mechanism and a machine tail chain wheel driving mechanism. The machine head chain wheel driving mechanism is a first hydraulic motor, and the machine tail chain wheel driving mechanism is a second hydraulic motor. A hydraulic system for driving the first hydraulic motor and a hydraulic system for driving the second hydraulic motor include identical hydraulic components and each comprise a three-position four-way electromagnetic directional valve, a two-position two-way electromagnetic directional valve, a two-position three-way electromagnetic directional valve, an energy accumulator andan oil supplementing valve group. The driving system is applicable to rapid starting and stopping of a scraper conveyor under the heavy-load condition, meanwhile, the chain tension can be adjusted inreal time, the problem of power unbalance in a dual-driving system is solved, and the driving system is simple in structure and long in service life.

Description

Technical field [0001] The invention relates to the technical field of underground material transportation, in particular to a drive system and a control method of a scraper conveyor. Background technique [0002] Scraper conveyor is a kind of continuous transportation machinery, which has the advantages of large transportation capacity, wide adaptation to the environment and simple maintenance. It is widely used in coal mines in fully mechanized mining faces. The traction drive system of the traditional scraper conveyor is mainly composed of a drive motor, a reducer, a soft starter, a sprocket and other devices. The drive mechanism composed of the drive motor and the reducer is used to drive the sprocket to rotate, and the soft starter is used to start or Turn off the drive motor. [0003] However, the above-mentioned scraper conveyor traction drive system has the following defects: 1. The high-power scraper conveyor usually uses two drive systems to drive the head sprocket and t...
