Hydraulic support and pedal plate device thereof

Abstract

The invention discloses a pedal plate device of a hydraulic support. The pedal plate device comprises a pedal plate (1) and a fixed bottom plate (2) which is connected with the pedal plate (1); one side of the pedal plate (1) is hinged with the fixed bottom plate (2) and a hinge shaft is parallel to the width direction of the fixed bottom plate (2); the pedal plate device also comprises a drivingdevice capable of driving the pedal plate (1) to rotate round a hinge point of the pedal plate (1) and the fixed bottom plate (2), and a locking device for locking or unlocking the working position of the pedal plate (1); and when the hydraulic support works, the corresponding angle between the pedal plate (1) and the working surface can be adjusted according to the included angle between the working surface and a horizontal plane so as to facilitate the walking of an operator and operation of equipment, and the pedal plate device is convenient to disassemble and maintain. Moreover, the invention also provides the hydraulic support comprising the pedal plate device.

Description

technical field [0001] The invention relates to the technical field of hydraulic supports, in particular to a pedal device of a hydraulic support. In addition, the present invention also relates to a hydraulic support comprising the above-mentioned foot pedal device. Background technique [0002] Hydraulic support is one of the most important technical equipment of comprehensive mechanized coal mining face. Indispensable supporting equipment, mainly used in the longwall fully mechanized mining face of the horizontal plane and gently inclined thick coal seam along the bottom floor for one-time caving and full-height mining. [0003] Generally, the staff work and walk on the working surface through the foot pedals arranged on the hydraulic support. In the prior art, the space for the staff to walk on the hydraulic support is mostly the foot pedals arranged horizontally on the fixed floor. The board and the pedal are rigidly connected with the fixed base plate and cannot be d...

AI Technical Summary

Problems solved by technology

[0005] Therefore, the rigid installation structure of the pedals of the hydraulic support in the prior art cannot adapt to the needs of the current coal mining environment, which brings relatively large changes to the staff's walking and equipment, and the staff is prone to regression, sprain or injury during the operation process. Collision, there is a relatively large hidden danger to personal safety

[0006] Moreover, the connection mode of the pedals in the prior art is a rigid connection, which is not easy to disassemble, repair and install, which affects the working efficiency
