Abstract
The utility model discloses a device for preventing a steel wire rope from breaking away from a pulley groove of a crane. The device for preventing the steel wire rope from breaking away from the pulley groove of the crane is characterized by comprising a left supporting plate and a right supporting plate which are installed under a crane girder, wherein the left supporting plate and the right supporting plate are positioned at the two outer ends of a pulley block respectively; central spindles in the direction of the pulley groove are installed between the left supporting plate and the right supporting plate at intervals; the central spindles are fixed by spacers and open pins which are arranged on the end parts thereof; two unconnected sleeves are sleeved outside the central spindles; the sleeves are parallel to two end surfaces of the pulley block; the steel wire rope on the pulley block is positioned between adjacent sleeves. The device for preventing the steel wire rope from breaking away from the pulley groove of the crane is reasonable in structural design, convenient and practical; the device ensures that the running direction of the steel wire rope is within a guiding range of the pulley groove, so that the steel wire rope is not dragged out of the pulley groove, the crane can work normally and the safety of people and equipment can be ensured.
Description
Technical field
The utility model relates to a kind of driving operation auxiliary device, relates in particular to a kind of driving steel wire rope groove separation preventing device.
Background technology
Driving is accounting for sizable ratio, because driving adopts assembly pulley steel wire strand rope structure, in use steel rope is subject to the askew impact that skews the factors such as abnormal operation such as hanging, easily by steel rope de-groove from pulley groove, will produce the cliding friction motion with the fixed pulley axis mill after steel cable slot disengaging,, there is huge potential safety hazard in the serious harm fixed pulley axis.The situation that this groove separation preventing device can effectively be controlled steel cable slot disengaging occurs.
The utility model content
The purpose of this utility model is in order to make up the deficiency of prior art, and a kind of driving steel wire rope groove separation preventing device is provided, and it is simple in structure, convenient and practical, has avoided steel cable slot disengaging, causes fixed pulley axis frayed, the problems such as generation personnel, device security hidden danger.
The utility model is achieved through the following technical solutions:
A kind of driving steel wire rope groove separation preventing device, it is characterized in that: include the left and right support plate be arranged under the driving girder, described left and right support plate lays respectively at two outer ends of pulley wheels, between described left and right support plate, interval is equipped with along the mandrel of pulley groove direction, described mandrel is fixed by pad and the spring cotter of its end, described mandrel is set with the disjunct sleeve of two joints outward, and described sleeve all is parallel to the two-wheeled end face of pulley, and the steel rope on pulley is between adjacent sleeve.
Free-running fit between the described steel rope sleeve cylinder face corresponding with it.
In normal lifting process, because steel rope is vertically downward, so cable wire does not reach sleeve pipe.Up-and-down movement in steel rope pulley groove in the vertical direction, complete normal lifting action., askew skewing occurs and hang phenomenon during not at the same vertical line when weight and suspension hook, the guide range that steel rope can be offset out pulley groove causes steel cable slot disengaging.The preventing wire rope from falling slot device can make the direction of steel rope operation in the guide range of pulley groove the askew angle of effectively controlling the steel rope skew that skews when hanging occurs, and steel rope will not can be hauled out pulley groove, and driving can normally move.The askew two-section sleeve be enclosed within on mandrel that skews while hanging can rotate along with the motion of steel rope respectively, and rolling movement relative to steel rope reduces the damage to steel rope.
The utility model has the advantages that:
The utility model reasonable in design, convenient and practical, make the direction of steel rope operation in the guide range of pulley groove, steel rope will not can be hauled out pulley groove, and driving can normally move, and has guaranteed the safety of personnel, equipment.
The accompanying drawing explanation
Fig. 1 is the utility model cutaway view.
Fig. 2 is the utility model local structure schematic diagrams.
The specific embodiment
Referring to accompanying drawing, a kind of driving steel wire rope groove separation preventing device, include the left and right support plate 1,2 be arranged under the driving girder, left and right support plate 1,2 lays respectively at two outer ends of pulley wheels 3, between left and right support plate 1,2, interval is equipped with the mandrel 4 along the pulley groove direction, mandrel 4 is fixing by pad 5 and the spring cotter 6 of its end, the outer disjunct sleeve 7-1 of two joints, the 7-2 of being set with of mandrel 4, sleeve 7-1,7-2 all are parallel to the two-wheeled end face of pulley 8, and the steel rope on pulley 89 lays respectively between adjacent sleeve.Free-running fit between described steel rope 97 faces of sleeve corresponding with it.
Claims (2)
1. a driving steel wire rope groove separation preventing device, it is characterized in that: include the left and right support plate be arranged under the driving girder, described left and right support plate lays respectively at two outer ends of pulley wheels, between described left and right support plate, interval is equipped with along the mandrel of pulley groove direction, described mandrel is fixed by pad and the spring cotter of its end, described mandrel is set with the disjunct sleeve of two joints outward, and described sleeve all is parallel to the two-wheeled end face of pulley, and the steel rope on pulley is between adjacent sleeve.
2. driving steel wire rope groove separation preventing device according to claim 1 is characterized in that: free-running fit between the described steel rope sleeve cylinder face corresponding with it.
