Abstract
Disclosed is a groove disengaging preventing device of a steel wire rope of a pulley in a multi-section telescopic arm. A telescopic hydraulic cylinder, the pulley and the steel wire rope are arranged in the multi-section telescopic arm; a shaft is installed on the end portion of a piston of the telescopic hydraulic cylinder; a first flange and a second flange are welded to the shaft; a threaded hole is formed in the first flange; the pulley is installed on the outer side of the first flange through a bearing; two sides of the bearing are sealed through a circlip for a hole. The groove disengaging preventing device of the steel wire rope of the pulley in the multi-section telescopic arm is characterized in that a right rope limiting piece is installed on the first flange of the shaft through a bolt; the circlip, of the shaft, for a hole is sleeved with a shaft sleeve; a left rope limiting piece is connected with a flange surface of the shaft sleeve through a bolt; the shaft sleeve at the tail end of the shaft is axially positioned through a pin; the gap between a protection cover formed by the left rope limiting piece and the right rope limiting piece and the pulley is smaller than two thirds the diameter of the steel wire rope. The groove disengaging preventing device of the steel wire rope of the pulley in the multi-section telescopic arm is simple in structure and convenient to assemble and disassemble and adapts to extremely limited space in the telescopic arm.
Description
Technical field
The utility model relates in a kind of construction machinery and equipment pulley wire rope groove separation preventing device in multi-stage telescopic arms, is specially for when the construction machinery and equipment multi-stage telescopic arms expanding-contracting action, in the pulley rotation process, prevents the safety guard that steel rope is deviate from from pulley groove.
Background technology
Construction machinery and equipment when the flexible operation, drives steel rope pull out or retract telescopic boom by hydraulic ram and assembly pulley with multi-stage telescopic arms.In places such as hydraulic ram ends, a pair of fixed pulley need to be set, connect and stretch out steel rope and retraction steel rope respectively.The hydraulic ram end is connected with axle, and a pair of assembly pulley assembles and is connected from the both sides of axle.
Because hydraulic ram, pulley and steel rope all are assemblied in arm, in course of action as occurred being prone to accident by steel cable slot disengaging, and be inconvenient to keep in repair.Therefore, for guaranteeing not there will be de-groove at telescopic boom steel rope in telescopic process, must in very limited space, take certain anticreep groove measure.
The utility model content
The problem existed for above-mentioned prior art, the purpose of this utility model realizes in the pulley rotation process, preventing the safety guard-safeguard that steel rope is deviate from from pulley groove when construction machinery and equipment multi-stage telescopic arms expanding-contracting action.
The utility model is achieved in that
A kind of for pulley wire rope groove separation preventing device in multi-stage telescopic arms, be equipped with telescopic oil cylinder in described multi-stage telescopic arms, pulley and steel rope, the pistons end installation shaft of described telescopic oil cylinder, be welded with the first flange and the second flange on axle, offer tapped bore on the first flange, described pulley is arranged on the outside of the first flange by bearing, both sides at bearing are sealed by circlip for bore, right limit rope part is arranged on the first flange of axle by bolt, be set with axle sleeve outside the circlip for bore of axle, left limit rope part is connected with the flange face of axle sleeve by bolt, shaft end is used pin to carry out axial location to axle sleeve, protective case and the gap between pulley that left limit rope device and right limit rope device form need be less than 2/3 of wirerope diameter.
Further, described left limit rope device and right limit rope device fasten assembling by bolt.
More preferably, described left limit rope device and right limit rope device are the semicircle annular, and have the parallel Cutting Edge of the width slightly larger than diameter of pulley or Cutting Edge in an acute angle.
More preferably, described left limit rope device and right limit rope device have convex edge over against the mask of steel rope.
The beneficial effects of the utility model are:
1, this pulley wire rope groove separation preventing device forms the protective case of semi-surrounding to pulley and steel rope, has effectively protected steel rope in the telescopic boom telescopic process, prevents that steel rope from deviating from pulley groove, the generation of minimizing accident and maintenance of equipment.
2, this pulley wire rope groove separation preventing device is detachable structure, simple in structure, assembling and easy accessibility.
3, described structure is for adapting to very limited space in telescopic boom.
The accompanying drawing explanation
The front view that Fig. 1 is the utility model embodiment;
The A-A cutaway view that Fig. 2 is the utility model embodiment Fig. 1;
The birds-eye view of Fig. 1 that Fig. 3 is the utility model embodiment;
The cutaway drawing that Fig. 4 is another embodiment of the utility model.
Reference numeral in above-mentioned figure:
1 telescopic oil cylinder, 2 pulleys, 3 left limit rope devices, 4 steel ropes, 5 right limit rope parts, 6 first flanges, 7 second flanges, 8 bearings, 9 axles, 10 axle sleeves, 11 circlip for bores, 12 pins, 13 convex edges
The specific embodiment
Following examples are used for illustrating the utility model, but are not used for limiting scope of the present utility model.
As Figure 1-3, pulley wire rope groove separation preventing device in the utility model construction machinery and equipment multi-stage telescopic arms, as Figure 1-3: solid line is partly the concrete structure of groove separation preventing device, the installation environment that dotted portion is groove separation preventing device.
In order to realize protecting the effect of steel rope 4, protective case and the gap between pulley 2 that left limit rope device 3 and right limit rope device 5 form need be less than 2/3 of steel rope 4 diameters, in the course of the work steel rope 4 are formed to effectively protection.Left limit rope device 3 and right limit rope device 5 are the semicircle annular, and have the parallel Cutting Edge of the width slightly larger than diameter of pulley or Cutting Edge in an acute angle.
As shown in Figure 4, another embodiment of the present utility model, described left limit rope device 3 and right limit rope device 5 have convex edge 13 over against the mask of steel rope.
