Novel sinking hoist

Abstract

The invention relates to a novel sinking hoist; a speed reducer (5) is connected with a motor (7) and a main shaft device (1) through an elastic pin coupling (6) and a gear coupling (3); a disc-shaped brake device (2) is allocated; an idle end is connected with a driving device (12) of a depth indicator; the indicator monitors the depth of sinking and is controlled by a control box (9), a lubrication station (4) and a hydraulic station (8) provide lubrication and brake oil pressure. A main shaft (1.12) is fixed by a rolling element bearing house (1.1); a motile reel (1.4) and a fixed reel (1.8) are arrayed; the two ends fix a fabricated brake disc (1.3); the reel is embedded with a plastic liner (1.9); the motile reel is fixedly connected with a left and a right wheel hubs (1.5 and 1.7) and is internally provided with two semi-copper tiles (1.6); the motile reel does not rotate along with the main shaft and is connected with a rope adjusting clutch (1.2); the fixed reel is fixedly connected with a left and a right wheel hubs (1.10 and 1.11) and rotates along with the main shaft. The sinking hoist has unique structure.

Description

technical field [0001] The invention belongs to the technical field of mine hoists, in particular to a novel sinking hoist. Background technique [0002] Sinking hoist is the preliminary equipment of mine hoist, mainly used for drilling and building wells, lifting and lowering personnel, transporting materials and equipment in coal mines, metal mines and non-metal mines. The mine hoist is developed from the hand potter's wheel. With the development of science and technology, the hoist has developed from KJ type to JKA type, and from XKT type, XKTB type to the current JK type formed product. [0003] The mechanical part of the mine hoist is composed of the working mechanism - the main shaft device; the transmission mechanism - the reducer, the coupling; the braking system - the brake, the hydraulic station; the observation control system - the depth indicator and the depth indicator transmission; the protection system - It is composed of tachogenerator device, guard plate, s...

AI Technical Summary

Problems solved by technology

[0005] 1) The tangential key at the tangential key connection in the spindle device is prone to loosening; processing the keyway on the spindle will affect the strength of the spindle

[0006] 2) The brake disc has axial series motion, which affects the safety and reliability of the brake

[0007] 3) The rope adjustment clutch has a fault of difficult clutching

[0008] 4) Rope adjustment oil cylinder or interlock valve leaks oil and pollutes the brake disc, seriously affecting the safety and reliability of the brake

[0009] 5) It is difficult to adjust the delay time of the hydraulic delay secondary brake of the hydraulic station

[0010] 6) The service life of the serpentine spring in the serpentine spring coupling is short, and it is not easy for spare parts users to solve it

[0011] 7) In the transmission device of the discharge type depth indicator, the backlash of the tooth side of the gear spoke is easy to change, which will cause the shaft breaking accident of the transmission device and seriously affect the safe operation of the hoist
