Problems solved by technology

However, when encountering an uneven top plate or an uneven bottom plate, there will be a situation where the uneven surface contacts the plane. At this time, the actual contact points are only three points that are not on the same straight line, and these three points are often not on the same line. The position of the column socket causes the top beam or bottom beam to bear huge bending moment and torque, so the hydraulic support is often made very heavy and the price will be high

Embodiment Construction

[0019] combine figure 1 , figure 2 and image 3 , figure 1 The position of a column socket of the present invention applied to the top beam and the bottom beam of the fully mechanized support is given. The fully mechanized mining support includes a top beam 13 , a bottom beam 14 , a four-bar mechanism 3 and a pillar 4 . The top beam 13 and the bottom beam 14 are respectively provided with column sockets connected with the upper end and the lower end of the hydraulic prop 4, wherein figure 2 An embodiment in which a column socket of the present invention is applied to a top beam is given. In this embodiment, a column socket 1 includes a column socket body 5, a column socket top surface 8, a device connected to a pillar, and a socket connected to a top beam. structure. The device connected with the pillar 4 includes a ball socket 7, a pin 9, and a small pin 12, and the structure fixed with the top beam is a welded structure. In this embodiment, the socket top surface 8 i...

Abstract

The invention discloses a socket which is used for a top beam or a bottom beam of a hydraulic bracket for coal mine under the shaft. The socket comprises a socket body 5, socket top faces 8, a device connected with a hydraulic prop and a structure fixed with the top beam and is characterized in that the top faces 8 of the socket extrude out of a top face 10 of the top beam 13 or a bottom face 11 of the bottom beam 14. The bending moment suffered by the top beam or the bottom beam is reduced in such a way that all the top faces 8 of the socket are first in contact with a top plate and a bottom plate, and therefore the aims of reducing weight and cost of a bracket are achieved. The socket disclosed by the invention is particularly suitable for supporting uneven or softer top plates and bottom plates.

Description

technical field [0001] The invention relates to a column socket used for a coal mine underground hydraulic support. Background technique [0002] There are two types of hydraulic supports, one is the support described in "General Technical Specifications for Sliding Roof Beam Hydraulic Supports". Such as suspension top beam hydraulic support (Chinese patent application No. 88104291.9) and chain suspension hydraulic support (Chinese patent application No. ZL200510070729.7). The other is the hydraulic support described in "General Technical Conditions for Fully Mechanized Mining Hydraulic Support". These two types of hydraulic supports are used to connect the top surface of the column socket with the upper end of the hydraulic prop to be set under the top surface of the top beam. The purpose of this is to keep the top surface of the top beam in a complete planar shape. for better contact with the roof. The bottom surface of the column socket connected with the lower end of ...
