Abstract
The utility model relates to a mine hoist, in particular to a mine hoist radial gear block type rope-adjusting clutch blocking device. The mine hoist radial gear block type rope-adjusting clutch blocking device comprise two semi-circle bodies, wherein the two semi-circle bodies are connected as a whole through a rotating shaft and provided with functions of opening or closing. The two semi-circle bodies are arranged on a piston rod in a sleeved mode after being closed, wherein the piston rod is arranged between an oil tank device and a stirring ring. The length of the two semi-circle bodies is properly capable of enabling one end of a rope-adjusting clutch to be abutted against an oil tank cover of the oil tank device and another end of that to be abutted against a plane of one side of the stirring ring when the rope-adjusting clutch is closed. The blocking device is simple in structure, low in manufacturing cost, convenient to use and capable of eliminating safety hazards of a hoist rope-adjusting clutch and improving safety performance of a 2JK mine hoist under the condition that a rope-adjusting clutch structure in the prior art is not needed changing.
Description
Technical field
The utility model relates to mine hoist, specifically a kind of mine hoist radial gear block type rope-adjusting clutch closing appliance.
Background technology
Known mine hoist with radial gear block type rope-adjusting clutch as shown in Figure 1 and Figure 2, by interlocked valve 1, cylinder apparatus 2, mobile hub 3, stir ring 4, wheel hub 5, win 6 in succession, tooth piece 7, internally toothed annulus 8 form.The reel that moves about is by the sliding dress of a wheel and main shaft, and can relatively rotate with main shaft, internally toothed annulus 8 is bolted on the former of reel that moves about, wheel hub 5 hot chargings are on main shaft, mobile hub 3 links to each other with the piston rod of cylinder apparatus 2 by stirring ring 4, and cunning is contained on the wheel hub, 6 is connected with tooth piece 7 by winning in succession, cylinder apparatus 2 is installed on bearing seat or the support, and interlocked valve 1 is installed in cylinder apparatus 2 left sides.When pressure oil enters oil cylinder and closes the chamber from the A pipe, the pressure oil pushing piston moves right, move to right by the mobile hub 5 of ring 4 drives of stirring that is connected with piston rod, the 6 promotion tooth pieces 7 of winning in succession are moved up, and with the internally toothed annulus engagement, the piston rod of interlocked valve 1 inserts in the groove of piston rod in the cylinder apparatus 2 simultaneously, prevent that the cylinder apparatus piston rod from moving to left, this moment, power-transfer clutch closed (seeing C state among Fig. 2), and the reel that moves about is connected with main shaft, and gig is in normal working.When pressure oil enters from the B pipe, must pass through first interlocked valve 1, make in the groove of piston rod by piston rod in the cylinder apparatus 2 of interlocked valve 1 and withdraw from, then pressure oil enters cylinder apparatus and leaves the chamber, pushing piston moves to left, and moves to left by the mobile hub 5 of ring 4 drives of stirring that is connected with piston rod, and the 6 pulling tooth pieces 7 of winning in succession are moved down, tooth piece 7 is thrown off with internally toothed annulus 8, i.e. throw-out-of clutch (seeing D state among Fig. 2).Reel and the main shaft disengagement of moving about this moment.The reel that will move about braking starts gig, rotating spindle, and namely dead block relatively rotates with the reel that moves about, and can reach the adjusting level or adjust the long purpose of rope.
The potential safety hazard that this kind power-transfer clutch exists is: only prevent that the piston rod of cylinder apparatus 2 from moving to left in the groove by piston rod in the piston rod insertion cylinder apparatus 2 of interlocked valve 1, cause the reel that moves about to separate with main shaft.If equipment uses through long-time, when the sealing property of Hydraulic Elements goes down, the phenomenon that the pressure oil seepage can occur, pressure oil drop by drop is gathered in the B pipe, and long time integration can cause interlocked valve to open, and piston rod moves to left, to rope-adjusting clutch is thrown open, causing the reel sport car that moves about out of control, such as domestic in recent years several times gig derailing accident, all is that rope-adjusting clutch throws open and causes.
The utility model content
The utility model is intended to solve above-mentioned because rope-adjusting clutch throws open the gig derailing accident problem that causes, and a kind of improper mine hoist radial gear block type rope-adjusting clutch closing appliance of opening of rope-adjusting clutch that prevents is provided.
The utility model solves described problem and adopts following technical scheme:
A kind of mine hoist radial gear block type rope-adjusting clutch closing appliance, comprising that two of being connected as a single entity by rotating shaft have opens or the semicircular body of closure function, be sleeved on cylinder apparatus after described two semicircular body closures and stir on the piston rod between the ring, the one end contacted on the oil cylinder cover of cylinder apparatus when the length of two semicircular body made rope-adjusting clutch close just, and the other end contacts on the plane of stirring ring one side.
Compared with prior art, the beneficial effects of the utility model are: closing appliance is simple in structure, cost of manufacture is cheap, need not to change in the situation of original rope-adjusting clutch structure, use very easily this device, can eliminate the potential safety hazard of gig rope-adjusting clutch, improve the safety performance of 2JK type mine hoist.
The utility model further technical scheme is: a semicircular body in described two semicircular body is fixed with at hinged rotating shaft coupling end and makes two semicircular body open or closed handle bolted lockhole when the other end of described two semicircular body is respectively arranged with for closure.

Fig. 2 is mine hoist radial gear block type rope-adjusting clutch disengagement/closure state scheme drawing.
Fig. 3 is the utility model example structure scheme drawing.
Fig. 4 is Fig. 3 right elevation.
Fig. 5 is that the utility model uses view.
Among the figure: interlocked valve 1, cylinder apparatus 2, mobile hub 3 is stirred ring 4, and wheel hub 5 wins 6 in succession, tooth piece 7, internally toothed annulus 8, left semicircle body 9, right semicircle body 10, hinged rotating shaft 11, handle 12, bolt 13, locking 14.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment.
Referring to Fig. 3, Fig. 4, Fig. 5, closing appliance 14 is comprised of left semicircle body 9, right semicircle body 10, hinged rotating shaft 11, handle 12, bolt 13, left semicircle body 9 is connected a side by hinged rotating shaft 11 connections with the right semicircle body, opposite side is respectively arranged with the connection lockhole of bolt 13, is connected with one near the position of hinged rotating shaft 11 on right semicircle body 10 two semicircular body are opened or closed handle 12.
Referring to Fig. 5, when rope-adjusting clutch closes, open two semicircular body, closing appliance 14 is enclosed within on the piston rod, fix the tie bolt 13 of closing appliance 14 bottoms, closing appliance 14 left ends contact on the oil cylinder cover of cylinder apparatus 2, right-hand member contacts on the plane of stirring ring 4 left sides, makes all to be in spacing state about piston rod, and this moment, rope-adjusting clutch was in blocking, if do not remove closing appliance 14, rope-adjusting clutch is not opened.When need are opened rope-adjusting clutch, lay down first the tie bolt 13 of closing appliance 14, hold on the handle 12 and carry, remove closing appliance 14, removal is spacing to piston rod in the cylinder apparatus 2, and pressure oil enters cylinder apparatus 2 and leaves the chamber, piston rod moves to left, power-transfer clutch is opened, and the reel of realizing moving about separates with main shaft, carries out next step adjustment.
