Description
Technical field
The utility model belongs to the mine hoist technical field, and what relate generally to is a kind of rope-adjusting clutch oil cylinder with the piston rod lockout mechanism.
Background technology
Gig is the major equipment of mine transportation, and rope-adjusting clutch is the important component part of double-drum hoist.When gig need change hoisting depth, when needs are adjusted two lifting container relative positions, must be undertaken in other words by rope-adjusting clutch.Rope-adjusting clutch comes mobile tooth piece by hydraulic cylinder for adjusting rope, and the tooth piece is separated or combination with internally toothed annulus, reaches the purpose of transferring rope.This shows that in case the tooth piece separates with internally toothed annulus, the reel that moves about just can freely rotate and not restricted by main shaft on main shaft.Therefore, tooth piece position must be pinned behind the accent knot bundle, the tooth piece separates with internally toothed annulus when avoiding gig work, causes serious accident.
Present rope-adjusting clutch tooth piece is lived the hydraulic cylinder for adjusting rope piston rod by the hydraulic interlocking block of valve and is locked.Its principle of work is: at first by pressure oil the pin of interlocked valve is extracted when needs are opened power-transfer clutch, pin is extracted back conducting oil cylinder disengagement chamber oil circuit, and pressure oil enters the oil cylinder disengagement chamber, and piston rod is moved to the disengaging of clutch direction; Give the oil cylinder binding cavity logical oil after transferring the knot bundle, oil cylinder disengagement chamber decompression and simultaneously by the check valve oil return on the interlocked valve, the interlocked valve pin stretches out under the effect of spring force and withstands on the piston rod, pin just entered in the groove when groove on piston rod arrived, and made piston rod not move forward and backward and pinned the tooth piece.
Because interlocked valve is by hydraulic-driven, automation mechanized operation, therefore the normal operation to hydraulic efficiency pressure system has extra high requirement, definitely can not misoperation.(in this sense, herein degree of automation excessive risk is big more more.) in addition, because pin itself is again spool, after pin surfaces is extruded distortion, just can't move flexibly, thereby influence the normal use of interlocked valve.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this utility model is to propose a kind of rope-adjusting clutch oil cylinder with the piston rod lockout mechanism.
For the technical solution adopted in the utility model that realizes foregoing invention is: a kind of rope-adjusting clutch oil cylinder with the piston rod lockout mechanism, the front ends that described piston rod lockout mechanism is positioned at oil cylinder covers, the anterior end cap of described oil cylinder is a tubular structure, the piston rod lockout mechanism is provided with cam ring and cam ring is nested with on the end cap of oil cylinder tubular structure, has on the end cap of oil cylinder tubular structure in order to the spherical pore of placement positioning steel ball with in order to place the mounting hole of locating dowel pin; On the outer wall of described piston rod front end, has detent; Several lock balls of control oil cylinder piston bar action are positioned at the detent of spherical pore on the cylinder cover and piston rod front end and are fitted on the inwall of cam ring; The cam ring corner is carried out spacing locating dowel pin to be installed on the end cap of oil cylinder tubular structure by mounting hole; Be provided with the locating dowel pin that the rotation of cam ring is controlled, described locating dowel pin is arranged in the knock hole on the cylinder cover, and is provided with and makes operator handle that locating dowel pin moves and the retracing spring that locating dowel pin is inwardly resetted.
A kind of rope-adjusting clutch oil cylinder with the piston rod lockout mechanism that the utility model proposes has the advantages that structure design is ingenious, safe reliability is high, simple to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the utility model running condition scheme drawing.
The enlarged drawing of locating dowel pin in Fig. 3 the utility model.
Among the figure: 1, cam ring, 2, cylinder cover, 3, piston rod, 4, locating dowel pin, 5, lock ball, 6, locating dowel pin, 7, handgrip, 8, retracing spring, 9, back-up ring.
The specific embodiment
With specific embodiment the utility model is illustrated in conjunction with the accompanying drawings:
As shown in Figure 1, and with reference to Fig. 2, Fig. 3: a kind of rope-adjusting clutch oil cylinder with the piston rod lockout mechanism, described piston rod lockout mechanism is positioned on the anterior end cap 2 of oil cylinder, the front end of described cylinder cover 2 is a tubular structure, the cam ring 1 of piston rod lockout mechanism setting is nested with on the end cap of oil cylinder tubular structure, has on the end cap of oil cylinder tubular structure in order to the circular port of placement positioning steel ball 5 with in order to place the mounting hole of locating dowel pin 4; On the outer wall of described piston rod 3 front ends, has detent; Several lock balls 5 of control oil cylinder piston bar action are positioned at the detent of circular port on the cylinder cover and piston rod and are fitted on the inwall of cam ring; The cam ring corner is carried out spacing locating dowel pin 4 to be installed on the end cap of oil cylinder tubular structure by mounting hole; Be provided with the locating dowel pin 6 that the rotation of cam ring is controlled, on the end cap of oil cylinder tubular structure, have at least two knock holees; Described locating dowel pin is arranged in one of them knock hole on the cylinder cover, and is provided with and makes operator that locating dowel pin moves 7 and retracing spring 8 that locating dowel pin 6 is inwardly resetted.Be equipped with back-up ring 9 on the cylinder cover 2 to the cam ring axial location.
As shown in Figure 1: be the piston rod latched position this moment, and the high point of cam ring 1 bore area limits lock ball 5 and radially can not move, and lock ball 5 is stuck in the groove of piston rod 3, thereby lock piston bar 3 can not move; Locating dowel pin 6 was inserted in the knock hole and by spring and withstood and can not withdraw from this moment, thereby guaranteed cam ring 1 reliable location and can not rotate, and then guaranteed that lock ball 5 can not withdraw from and lock piston bar 3.
As shown in Figure 2: when needs are transferred rope, at first should extract locating dowel pin 6 (locating dowel pin 6 is outwards moved, withdraw from knock hole), rotate handgrip 7 then cam ring is rotated, when locating dowel pin 6 arrives next knock hole, unclamp handgrip 7, allow locating dowel pin insert in the knock hole.The low spot of cam occurs the space to living steel ball between steel ball and cam at this moment, and steel ball can radially move, the piston rod release.If piston rod moved and can radially outwards move by the promotion steel ball this moment, thereby remove restriction to piston rod.
