Abstract
The utility model provides a kind of mining shackle, comprise the shackle body taken the shape of the letter U, shackle body comprises the left arm plate be arranged in parallel, right arm plate and the arc body being connected left arm plate upper end and right arm plate upper end, pulley support axle is arranged on left arm plate underpart and right arm plate underpart, pulley to be placed between left arm plate and right arm plate and to be supported on pulley support axle, left arm plate inner side surface arranges inside backstop, right arm plate inner side surface arranges inside backstop, two backstops are all positioned at directly over pulley outer rim, all gap is formed between each backstop and pulley outer rim, the size in this gap is much smaller than wirerope diameter.When wire rope is deviate from race, because this gap is little, wire rope can not enter, and this is just avoided occurring that wire rope squeezes bad phenomenon.
Description
Technical field
The utility model relates to technical field of coal mine, is specifically related to a kind of mining shackle.
Background technique
In coal production, it is a kind of common form that wire rope is used as traction, such as, connect extension pulley by wire rope.Wirerope-winding is on pulley, but the pulley erection support design supporting pulley is at present unreasonable, often occur that wire rope skids off pulley race and enters into gap between pulley and pulley erection support, wire rope is squeezed bad, cause security incident and impact is normal produces.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of mining shackle, avoids occurring that wire rope squeezes bad phenomenon.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of mining shackle, comprise the shackle body taken the shape of the letter U, shackle body comprises the left arm plate be arranged in parallel, right arm plate and the arc body being connected left arm plate upper end and right arm plate upper end, pulley support axle is arranged on left arm plate underpart and right arm plate underpart, pulley to be placed between left arm plate and right arm plate and to be supported on pulley support axle, left arm plate inner side surface arranges inside backstop, right arm plate inner side surface arranges inside backstop, two backstops are all positioned at directly over pulley outer rim, all gap is formed between each backstop and pulley outer rim, the size in this gap is much smaller than wirerope diameter.
Above-mentioned mining shackle, gap is of a size of 4mm.
Above-mentioned mining shackle, realize being divided into by the groove of shackle body upper and lower two-part backing pin to be arranged on left arm plate upper end portion and right arm plate upper end portion, backing pin is positioned at above pulley.
Above-mentioned mining shackle, backing pin is two, and time interval is arranged.
Above-mentioned mining shackle, arranges roller bearing between pulley and pulley support axle.
Above-mentioned mining shackle, pulley support axle is bolt, and the outer end of screw rod also wears the cotter pin preventing nut from departing from screw rod.
Left arm plate inner side surface arranges inside backstop, right arm plate inner side surface arranges inside backstop, two backstops are all positioned at directly over pulley outer rim, all form gap between each backstop and pulley outer rim, the size in this gap much smaller than wirerope diameter, because the size in gap is much smaller than wirerope diameter, therefore when wire rope is deviate from race, because this gap is little, wire rope can not enter, and this is just avoided occurring that wire rope squeezes bad phenomenon.

Below in conjunction with accompanying drawing to the further detailed description of the utility model:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the phantom of Fig. 1.
Fig. 3 is the structural representation of shackle body.
Fig. 4 is the phantom of Fig. 3.
Embodiment
As shown in Figures 1 to 4, a kind of mining shackle, comprises the shackle body 1 taken the shape of the letter U, and shackle body comprises the left arm plate, right arm plate and the arc body being connected left arm plate upper end and right arm plate upper end that be arranged in parallel.Pulley support axle 2 is arranged on left arm plate underpart and right arm plate underpart, pulley to be placed between left arm plate and right arm plate and to be supported on pulley support axle, left arm plate inner side surface arranges inside backstop, right arm plate inner side surface arranges inside backstop, two backstops are all positioned at directly over pulley outer rim, all form gap between each backstop and pulley outer rim, the size in this gap is much smaller than wirerope diameter.
Particularly, gap is of a size of 4mm.
Realize the groove of shackle body to be divided into upper and lower two-part backing pin 5 to be arranged on left arm plate upper end portion and right arm plate upper end portion, backing pin is positioned at above pulley, and backing pin can prevent wire rope from deviating from from pulley race.Backing pin is two, and time interval is arranged.
Particularly, between pulley and pulley support axle, roller bearing is set.
Particularly, pulley support axle is bolt, and the outer end of screw rod also wears the cotter pin preventing nut from departing from screw rod.
