Description
Technical field:
The present invention relates to a kind of safety method that hoists, particularly a kind of disconnected rope self-locking device.
Background technology:
Steel rope in lifting, hanging device happens occasionally because the reasons such as the de-groove wearing and tearing of overload lifting extruding cause disconnected rope to cause safety misadventure.The measure of taking is at present, steel rope is strengthened to daily inspection, finds in advance to exist the steel rope of damage to change in time, and whether this measure can not guarantee or not safety misadventure when fracture occurs steel rope.
Summary of the invention:
The object of the invention is to provide a kind of disconnected rope self-locking device that safety misadventure can not occur a kind of wire cable rupture.
The technical scheme that realizes the object of the invention is, a kind of disconnected rope self-locking device, , comprise housing, it is characterized in that: a gear supporter is set in housing, the center of this gear supporter is vertical hole, the top in this vertical hole is small top and big bottom taper hole, its underpart is the circular hole of tight-wire walking rope, a left side at described gear supporter, right side is respectively provided with a groove, two gears respectively normal-running fit with groove before, on the axle that rear wall is connected, a described left side, the cross-sectional plane of right gear is the arc matching with steel rope, on this arc side face, be evenly equipped with radial slot, a described left side, the vertical hole that the inner of right gear exposes to described gear supporter contacts with steel rope, left, right two relative and separated small top and big bottom Taper Pipe cunnings fit in the taper hole on described gear supporter top, an above-mentioned left side, part on the right side from straight hole for matching with steel rope of the pore of Taper Pipe, described body is left for working as, right body in conjunction with time formed aperture be less than the diameter of steel rope, a described left side, on the hole wall of the Taper Pipe that the right side is separated, prolong axial distribution and have arc pointed tooth, on a described left side, part on the right side from the upper surface of Taper Pipe and top board between be provided with four pressure springs, a left side on described gear supporter top, in right groove, be respectively provided with a fork, the middle part of this fork be rotatably supported in gear supporter groove before, on the fork axle that rear wall is connected mutually, the lower end of described fork is placed in uniform radial slot on described gear inner peripheral surface, a described left side, it is slippery with latch respectively that the lateral wall of the cone tube that the right side is separated is provided with pin-and-hole, the two ends of stay cord are connected with the upper end of described fork and the outer end of described latch respectively.
The present invention has the remarkable advantage that safety misadventure also can not occur while there is wire cable rupture compared with the prior art.
Accompanying drawing explanation:
Fig. 1 is front view of the present invention; Fig. 2 is the birds-eye view of Fig. 1; Fig. 3 is the A-A section-drawing of Fig. 1; Fig. 4 is the B-B section-drawing of Fig. 1; Fig. 5 is steel rope fork, stay cord and latch view while normally moving; Fork, stay cord and latch view when Fig. 6 is wire cable rupture.
The specific embodiment:
In conjunction with upper accompanying drawing, embodiments of the invention are further illustrated, at the interior gear supporter 10 that arranges of housing 1, the center of this gear supporter is vertical hole, the top in this vertical hole is small top and big bottom taper hole, bottom is the circular hole of tight-wire walking rope 7, a left side at described gear supporter, right side is respectively provided with a groove, two gears 3 respectively normal-running fiies with groove before, on the axle that rear wall is connected, a described left side, the cross-sectional plane of right gear is the arc matching with steel rope 7, on this arc side face, be evenly equipped with radial slot, a described left side, the vertical hole that the inner of right gear exposes to described gear supporter contacts with steel rope, (referring to Fig. 4).Sliding the fitting in the taper hole on described gear supporter top of left and right two relative and separated small top and big bottom Taper Pipes 5, the pore of the Taper Pipe of above-mentioned left and right separation is the straight hole matching with steel rope, described body is the body that is less than half body, when left and right body in conjunction with time formed aperture be less than the diameter of steel rope, on the hole wall of the described left and right Taper Pipe being separated, prolonging axial distribution has arc pointed tooth, between the upper surface of the Taper Pipe of described left and right separation and top board 2, is provided with four pressure springs 6.In the left and right groove on described gear supporter top, be respectively provided with a fork 4, the middle part of this fork is located to be rotatably supported on the fork axle that the front and back walls with gear supporter groove is connected mutually on the upper side, the lower end of described fork is placed in uniform radial slot on described gear inner peripheral surface, it is slippery with latch 8 respectively that the lateral wall of the described left and right cone tube being separated is provided with pin-and-hole, and the two ends of stay cord are connected with the upper end of described fork and the outer end of described latch respectively.(referring to Fig. 1,2)
Said gear supporter, the assembling of two Taper Pipes that are separated, gear supporter is placed on the base plate of housing, gear is installed, after fork, with bolt 9, be fixed in housing, again by the left side being separated, right Taper Pipe is placed in the taper hole of gear supporter, two latches are inserted respectively to a left side, part on the right side from the hole of Taper Pipe wall in, and four springs 6 are placed in to a left side, part on the right side from Taper Pipe end face on after, cover plate 2 is fixed on housing, now above-mentioned each spring is in compressive state, finally steel rope is through to housing cover and bottom plate hole, in separation cone pore and the vertical hole of gear supporter, in order to facilitate reeve, gear supporter, cover plate and base plate all make a left side, the Split type structure of right two halves.
Principle of work of the present invention and using method, the self-locking device of restricting breaking is arranged on the machine position, below at the disconnected rope of easy generation place.When normal handling weight, the running velocity of steel rope is normal speed comparatively slowly, now rope belt moving gear rotates, fork swings, because gear rotational speed is slow, the amplitude of oscillation of fork is less, stay cord can not pulled out latch from the pin-and-hole of separated cone tube, (referring to Fig. 5), when wire cable rupture, weight hurtles down, high-speed gear rotates, the inertia rotating due to high-speed gear impacts fork, make the fork amplitude of oscillation add senior general's latch pulls out from separated cone tube pin-and-hole, now separated Taper Pipe moves down steel rope locking under the effect of stage clip, steel rope can not be fallen, avoid resolving rope weight and fall to causing safety misadventure.
