Embodiment Construction

[0017] As shown in the figure: a frozen deep shaft second liner auxiliary pan lifting anti-turnover device, four lifting points 7 are used to install four steel wire ropes 2 on the hanging pan 1 to suspend the auxiliary pan, and two lifting points 8 are used for installation Two wire ropes are used as protection rope 3, hang safety belt, wire rope net bag, tool etc. The four steel wire ropes 2 are covered with 2-inch steel pipes 4 to prevent the soft rope from slack so as to detect the auxiliary hanging collision as early as possible. An auxiliary disk 5 is installed at the lower end of the steel wire rope 2, and 12 No. 16 channel steels are evenly welded on the bottom of the auxiliary disk 5 along the outer side. 6. When the auxiliary plate 5 is hanging and colliding, when it tilts in any direction around, the bottom ends of the 12 No. 16 channel steel 6 will tilt up and lean against the formwork or the well wall 9 to prevent the auxiliary plate from continuing to tilt, and a...

Abstract

The invention relates to an anti-flipping device for lifting and lowering a secondary liner auxiliary disc of a frozen deep shaft. Steel wire ropes and protection ropes are installed on a hanging scaffold; the steel wire ropes are sleeved with steel pipes, the auxiliary disc is installed at the lower ends of the steel wire ropes, and multiple channel steels are uniformly welded to the bottom of the auxiliary disc along the outer side of the auxiliary disc. The device is simple in structure and convenient to use, and can effectively prevent the accident that personnel and templates on the discfall into the shaft because the auxiliary disc is hit and turned over during construction of a secondary liner in the frozen deep shaft.

Description

technical field [0001] The invention belongs to equipment for building construction, in particular to a lifting and falling anti-turnover device for the secondary lining auxiliary plate of a frozen deep shaft. Background technique [0002] Frozen deep shaft (as of 2014, the deepest frozen shaft in my country is the auxiliary shaft and wind shaft of Hetaoyu Mine, with a freezing depth of 955m). 950m) will use a 1.0-1.5m high combined steel formwork to carry out the second lining of the inner wall from bottom to top. Therefore, it is necessary to renovate the two-layer or three-layer hanging pan (remove the large catches and bell mouths suspended from the lower pan, and cover them with openable wooden boards), and add an auxiliary pan to the lower part for demoulding and cleaning. Brush with oil. The auxiliary plate is hung with a wire rope, and it is easy to hang, touch and overturn the plate during the lifting process, causing the personnel on the plate and the formwork to ...
