Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the hanging equipment in the well of the sinking suspension plate of the present invention includes a stable rope 1 , an upper suspension pan 4 , a lower suspension pan 7 , a drilling work pan 8 , a wire rope suspension device 6 and a horizontal plugging device 3 . The lower end of the stabilizing rope 1 is connected to the upper suspension pan 4, and the upper suspension pan 4 is connected to the lower suspension pan 7 through the wire rope suspension device 6, and the sinking work pan 8 is arranged at the bottom of the lower suspension pan 7; The outer edge of 7 is provided with horizontal plug-in device 3. Several layers of beam sockets or annular grooves 5 adapted to the horizontal plug-in device 3 are provided along the vertical direction on the shaft wall 2 . In this embodiment, two layers of beam dimples or annular grooves 5 f...

Abstract

The invention discloses sinking platform in-well hanging equipment and method. The equipment comprises stabilizing ropes, an upper-layer platform, a lower-layer platform and a sinking work plate, the lower ends of the stabilizing ropes are connected with the upper-layer platform which is connected with the lower-layer platform through a steel wire rope hanging device, the sinking work plate is arranged at the bottom of the lower-layer platform, horizontal inserting and connecting devices are arranged at the outer edges of the upper-layer platform and the lower-layer platform, and a plurality of layers of beam sumps or annular grooves matched with the horizontal inserting and connecting devices are arranged along the vertical direction on the well walls. The sinking platform in-well hanging equipment integrates advantages of steel wire rope hanging of conventional platforms and beam-sump-type supporting of walking platforms, sinking platform in-well hanging without a ground sinking winch is realized, the problem that the sinking platform is difficult in hanging and inconvenient to move during existing deep vertical shaft construction are solved, and quickness, reliability and high efficiency in deep vertical shaft construction are realized.

Description

technical field [0001] The invention relates to mine excavation equipment, in particular to an in-well hanging equipment and method for a drilling suspension plate suitable for excavating deep vertical shafts. Background technique [0002] With the development of deep mineral resources in our country, digging deep shafts will be the main task of mine construction in our country in the future. For shaft construction in deep shafts (depth d≥1000m), due to the increase in the load of the sinking pan and equipment, the suspension capacity and rope capacity of the existing sinking winch are difficult to meet the requirements, making the traditional wire rope ground of the sinking pan The winch suspension method is no longer applicable to the construction conditions of deep vertical shaft shafts. Therefore, it is necessary to study the in-hole suspension technology of the sinking suspension plate, so as to reduce the suspension load of the sinking derrick and simplify the arrange...
