Abstract
The invention relates to a shackle, in particular to a special shackle for a gantry crane, and belongs to the technical field of a connecting piece. The shackle comprises a shackle body and a shackle pin, wherein the shackle pin used for connecting a left end arm and a right end arm is arranged at an open end, and both ends of the shackle are inwards collected in the shackle body; a left pin hole is formed in an end part, located at the open end, of the left end arm, and a left pin hole limiting stage used for limiting the shackle pin is arranged in the left pin hole; a right pin hole is formed in an end part, located at the open end, of the right end arm, and a right pin hole internal thread used for being connected with the shackle pin is arranged in the right pin hole; a shackle pin limiting stage is arranged on the outer circumference of the left end of the shackle pin; and a shackle pin internal thread is arranged on the outer circumference of the right end of the shackle pin. The shackle pin is inwards collected in the pin hole of the shackle body, so that mutual scratch between the shackle pin and a steel wire rope is avoided, the using safety is improved, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of shackle, the shackle of door machine special use, belongs to attaching parts technical field specifically.
Background technology
Unloading buckle assembly is for the load applying different, to connect the element of chain or line.Conventionally, unload buckle assembly or shackle and have one group of shackle arm, they are at one end connected to each other by bridge portion to obtain the shackle body that is roughly U shape; In the end relative with this bridge portion, shackle arm is opening.This shackle body can be closed with shackle pin, and shackle pin is placed in the opening in shackle arm conventionally.One end of one of them opening and shackle pin can be provided with screw thread, so that when shackle pin is threaded into shackle body, shackle pin is kept in position, connects jam nut on screw thread.Shackle pin ends screw section and end tail place bearing pin ear expose, and connect stressed steel rope on shackle pin, and door machine is steel rope meeting whipping in the process of lade, and bearing pin ear and the nut at shackle pin place are interrupted; When simultaneously steel rope is on being thrown to bearing pin ear and nut, also easy scratch steel rope.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thereby provide a kind of machine special-purpose shackle, avoided the mutual scratch of shackle pin and steel rope, improved safety in utilization and service life.
According to technical scheme provided by the invention, the special-purpose shackle of door machine comprises shackle body and shackle pin, shackle body comprises left end arm and right-hand member arm, left end arm and right-hand member arm one end are connected to form U-shaped shape by bridge portion, left end arm and the right-hand member arm other end form the open end of shackle body, it is characterized in that: described open end is provided with the shackle pin that connects left end arm and right-hand member arm, and shackle pin closes in shackle body in two ends.The end that is positioned at open end at left end arm is provided with left pin-and-hole, is provided with for the spacing left pin-and-hole limit dais of shackle pin in left pin-and-hole.The end that is positioned at open end at right-hand member arm is provided with right pin-and-hole, is provided with the right pin-and-hole negative thread for joining shackle pin in right pin-and-hole.Shackle pin left end excircle is provided with shackle pin limit dais, and shackle pin right-hand member excircle is provided with shackle pin negative thread.
Further, shackle pin left end center is provided with interior hexagonal counterbore.
Compared with the prior art the present invention has the following advantages:
The present invention is simple in structure, compact, reasonable, is received in the pin-and-hole of shackle body in shackle pin, avoids the mutual scratch of shackle pin and steel rope, has improved safety in utilization and service life.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is lateral plan of the present invention.
Description of reference numerals: hexagonal counterbore, 5-shackle pin negative thread, the left pin-and-hole limit dais of 6-, the right pin-and-hole negative thread of 7-, 8-left end arm, 9-right-hand member arm, 10-bridge portion, the left pin-and-hole of 11-, the right pin-and-hole of 12-, 13-open end in 1-shackle body, 2-shackle pin, 3-shackle pin limit dais, 4-.
The specific embodiment
The present invention is below further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1 and 2, the present invention mainly comprises shackle body 1 and shackle pin 2, shackle body 1 comprises left end arm 8 and right-hand member arm 9, and left end arm 8 and right-hand member arm 9 one end are connected to form U-shaped shape by bridge portion 10, and left end arm 8 and right-hand member arm 9 other ends form the open end 13 of shackle body 1.Described open end 13 places are provided with the shackle pin 2 that connects left end arm 8 and right-hand member arm 9, and shackle pin closes in shackle body 1 in 2 two ends.
