Abstract

The invention provides an anti-tipping device for a hydraulic support. The anti-tipping device comprises an H-shaped beam, at least one first jaw and at least one second jaw, wherein the H-shaped beam is arranged between a first hydraulic support base and a second hydraulic support base; the first hydraulic support base is connected to a first side plate of the H-shaped beam through the first jaw; and the second hydraulic support base is connected to a second side plate of the H-shaped beam through the second jaw. Correspondingly, the invention also provides the hydraulic support. Through the anti-tipping device, the hydraulic support can be prevented from tipping. The anti-tipping device for the hydraulic support is simple in structure and low in cost, the thrust and the moment are transferred through surface contact, and the anti-tipping device is stabile and durable and is not easily damaged.

Description

technical field [0001] The invention relates to the technical field of fully mechanized mining hydraulic supports, in particular to an anti-dumping device and a hydraulic support for hydraulic supports. Background technique [0002] In the coal seam, it is necessary to use the hydraulic support to support the roadway to avoid accidents, and for the hydraulic support in the inclined coal seam, it is also necessary to add anti-fall and anti-skid devices to prevent the hydraulic support from toppling or sliding. In actual use, if the inclination angle of the coal seam is greater than 10°, the support bracket should have an anti-skid device; if it is greater than 15°, the cover type and support cover type bracket should have an anti-skid device; Invert the device. There are many kinds of anti-tipping devices, such as flat-pull anti-tipping and cable-pull anti-tipping, etc., but these devices need to install multiple anti-tipping jacks, and the contact surface is point contact, ...
