Abstract
The utility model relates to an open type wedge sleeve, which comprises a wedge plate (1), a wedge (2), a steel wire rope (3) and an arc-shaped sheet (4). The section of the inner cavity of the wedge plate (1) is in a C shape. The steel wire rope is completely coated by the two sides of the C-shaped inner cavity of the wedge plate (1) and can not be pulled out in any direction, and thus the steel wire rope is secure and reliable and can be conveniently and rapidly replaced. One side of the top of the wedge plate (1) is welded with the arc-shaped sheet (4); one side of the wedge (2) corresponding to the arc-shaped sheet (4) is in an arc shape; all the acute angles are eliminated; and the steel wire rope (3) is prevented from being damaged and broken. Therefore, the service life of the steel wire rope (3) is greatly prolonged; the cost is saved; and the maintenance workload is reduced.
Description
One, technical field: the utility model relates to particularly a kind of technology of steel rope bonded assembly of grab bucket field.
Two, background technology: the grab bucket steel rope be connected with various ways, " O " closed wedge shell, wire clips, molten lead etc. are arranged, but installation is all arranged, dismantle difficult problem, the wedge shell damages easily, the easy fracture of wire of wire clips extruded cords rope is wasted also greatly, keeps in repair busier.
The anti-wear joint rope device of China Patent No. 99233868.9 grab buckets is a up-to-date technology that addresses this problem, but still exists following defective to improve.
1, it is characterized in that the combination technique of multiple structure, do not cut apart, do not implement separately.Be the general construction that universal abrasionproof pulley, open type wedge, elasticity protect rope sling, four unifications of through beam balance hinge, so big, complicated various, the inconvenience of manufacturing cost is implemented.
2, the open type wedge needs to protect rope sling with elasticity and is used, it is an eyelet hole that elasticity is protected the rope sling center, be difficult for passing when steel rope burr or distortion, elasticity is protected the top that rope sling places the open type wedge, has hindered the hammering chock and has moved back rope and installation, and it is that rubber, shell are steel pipe manufacturings that elasticity is protected the rope sling middle part, when the steel rope side force is big, still might squeeze out rubber, bump extension, make steel rope produce disconnected strand of fracture of wire with steel pipe.
3, elasticity is protected rope sling and the open type wedge must be installed in up and down on the perpendicular line, and being separated by must be more than 200 millimeter, thereby limited by bulk, little for grab bucket head side plate width, and just can not using of one can only be installed.
Three, summary of the invention: the utility model purpose be at above-mentioned defective a kind of divisible, independent use be provided, convenient implement, with low cost, quick dispatch, safe and reliable open type wedge cover of wedge.
The utility model is realized above-mentioned purpose by following technical method.
1, this open type cover of wedge comprises wedge, chock, steel rope.Can be used as a kind of independent accessory of crane grab, can be assemblied in grab bucket separately and go up direct connection switching rope or halliard, must not protect rope sling and be used with elasticity.
2, the wedge of open type cover of wedge has tapering, and the cross section inner chamber is " C " shape, and it is "T"-shaped that chock is.The complete wrapped wire rope in " C " shape wedge inner chamber both sides by chock locking steel wire rope firmly, can not get loose, thereby saved the elasticity that fixing anticreep uses and protected rope sling.When steel rope need be when the wedge top be folded to bending, arc-like sheet of top one face down bonding of wedge is eliminated acute angle, avoids steel rope in the bending of acute angle place and disconnected strand of fracture of wire.The corresponding side in chock top is also done a fillet, and its effect is identical with arc-like sheet.
3, be not subjected to the restriction of installing space, in any grab bucket, all can install and use.
The utility model is compared with prior art, and variation has taken place for technology and structure, and the open type cover of wedge can become the device of independent use, and it is lower to implement easier cost, and the dismounting steel rope is fast convenient, saves tens times of man-hours.After having saved elasticity and protecting rope sling, not anti-reflection of effect anti-wear, anti-short silk adds.Prolonged the service life of steel rope more.
Four, description of drawings: accompanying drawing is represented the concrete structure of the utility model open type cover of wedge.
Fig. 1 is the front elevation of open type cover of wedge;
Fig. 2 is the A-A cross sectional drawing of open type cover of wedge;
Fig. 3 is the chock front elevation of open type cover of wedge;
Five, the specific embodiment: the detail that describes the utility model embodiment below in conjunction with accompanying drawing in detail:
The utility model open type cover of wedge comprises wedge (1), chock (2), steel rope (3), arc-like sheet (4), and wedge (1) has tapering, intracavity section to be " C " shape, puts into wedge from opening part after steel rope (3) bending, does not have wire rope handling tired.Chock (2) is "T"-shaped, puts into steel rope (3) fake, with the hoisting force of steel rope (3) chock (2) and steel rope (3) is locked.Steel rope (3) is wrapped up fully by " C " shape wedge (1) both sides, and the part of locking does not expose, any direction pull or even destructive pullling can not make steel rope (3) deviate from, safe and reliable.Top one face down bonding of wedge (1) has arc-like sheet (4), eliminates acute angle, avoids steel rope (3) fracture of wire that causes damage when the bending of this place.The respective side of chock (2) top and arc-like sheet (4) is fillet, acts on identical with arc-like sheet (4).
Claims (2)
1, the utility model open type cover of wedge comprises wedge (1), chock (2), steel rope (3), camber sheet (4), it is characterized in that wedge (1) has tapering, intracavity section to be " C " shape, and steel rope (3) is wrapped up fully by " C " shape wedge (1) both sides.
2, open type wedge according to claim 1 is characterized in that wedge (1) one face down bonding has arc-like sheet (4); Chock (2) is "T"-shaped, and top one side is a fillet.
