[0002] As we all know, the guide sleeve or guide ring is an important part of the single hydraulic prop. In the current single hydraulic prop products, the guide is either guided by the cooperation between a certain section of the live post and the cylinder, or in the cylinder. Or the guide sleeve or guide ring is installed in the inner hole on the handle body, and the guide sleeve or guide ring installed on the cylinder or the handle body are all used to insert or other fixed methods, when the single hydraulic prop bears When eccentric load occurs in the load, the live column will deviate accordingly, which will cause eccentric wear to the guide sleeve or guide ring and the seal, and affect the service life of the seal, guide sleeve or sleeve ring

Abstract

The invention discloses a rigid-flexible combined guiding device of a single hydraulic prop, comprising a cylinder barrel (1), a handle (2), a guiding sealing seat (6), a connecting sleeve (7) at theupper end of a movable prop and a three-function valve seat (8). The rigid-flexible combined guiding device of the single hydraulic prop is characterized in that the guiding sealing seat is fixedly connected with the cylinder barrel by welding; an inner hole of the guiding sealing seat is internally provided with an upper guiding groove and a lower guiding groove which are respectively sheathed with a guiding ring (9) internally; and the middle-upper part of the cylinder barrel is fixedly connected with a floating type guiding sleeve (3) which is internally provided with a guiding ring (4). Inthe invention, as the guiding sealing seat is internally provided with two guiding rings, one guiding ring is rigid and the other guiding ring becomes a flexible guiding ring after being sheathed with a rubber ring; and after being additionally arranged in the cylinder barrel, the floating type guiding sleeve can generate proper deflection along with the movable prop when eccentric loading occurs, thus relieving the influence of the eccentric loading on the sealing part and the guiding sleeve or the guiding ring to a certain extent, and completely achieving the purposes of effectively reducing eccentric loading and wearing of the prop and improving the bearing capacity of the prop.

Description

technical field [0001] The invention relates to a support equipment for mines, in particular to a rigid-flexible combination guide device of a single hydraulic prop. Background technique [0002] As we all know, the guide sleeve or guide ring is an important part of the single hydraulic prop. In the current single hydraulic prop products, the guide is either guided by the cooperation between a certain section of the live post and the cylinder, or in the cylinder. Or the guide sleeve or guide ring is installed in the inner hole on the handle body, and the guide sleeve or guide ring installed on the cylinder or the handle body are all used to insert or other fixed methods, when the single hydraulic prop bears When eccentric load occurs in the load, the live column will deviate accordingly, which will cause eccentric wear to the guide sleeve or guide ring and the seal, and affect the service life of the seal, guide sleeve or sleeve ring.
