Embodiment Construction

[0015] The present invention will be further described below in conjunction with drawings and embodiments.

[0016] Such as figure 1 , the general hydraulic transmission system has the characteristics of cheap price, convenient adjustment and reliable operation, but it cannot achieve the output following the input and realize fast and proportional control. Therefore, some joints of the rotary kiln cleaning robot using hydraulic drive and control need to use general hydraulic transmission, while some joints need to use electro-hydraulic servo proportional technology to successfully complete the kiln lining cleaning operation.

[0017] It can be seen from the figure that the hydraulic system uses a variable pump to supply oil, its flow can be adjusted manually, and the maximum working pressure of the system can be adjusted through the relief valve. Electromagnetic reversing valve and travel switch are used to control the flow direction of hydraulic oil, so that the positive and...

Abstract

The invention discloses a rotary kiln liner clearing robot based on electro-hydraulic servo proportional driving and control. The rotary kiln liner clearing robot has four degrees of freedom to complete clearing work of rotary kilns with different specifications and sizes. Double crawler belts serve as a travelling device, and thus the kiln clearing robot has the enough traction obstacle crossingability and the large supporting area to improve the stability during clearing work. Parts of joints of the kiln clearing robot adopt combining of an electro-hydraulic servo and proportional control technology, a PLC analog quantity control technology and an upper and lower computer communication technology, thus driving and control over the robot are more flexible, more convenient and more reliable.

Description

technical field [0001] The invention relates to a rotary kiln lining cleaning robot based on electro-hydraulic servo proportional drive and control, which is suitable for the mechanical field. Background technique [0002] After the rotary kiln has been in operation for a period of time, the refractory bricks need to be cleaned due to distortion and deformation of the cylinder or cracks in the cylinder, which will damage and fall off the refractory bricks. Since the cleaning of the kiln lining is mainly done manually at present, the workers have to face harsh working environments such as strong noise, high dust and danger. Therefore, it is necessary to develop a rotary kiln lining cleaning robot to replace the manual cleaning of the kiln lining. Free yourself from harsh and dangerous working environments. Contents of the invention [0003] The invention proposes a rotary kiln lining cleaning robot based on electro-hydraulic servo proportional drive and control, which has ...
