[0024] Reference Figure 1 And Figure 2 The embodiment of the present application provides a double-track pulley release device for cooperating with a live pig conveyor to release a pulley, wherein in the prior art, the live pig conveyor comprises a first guide rail 10 and a second guide rail 20 used for guiding the movement of the pulley and connected at a predetermined included angle, wherein the opposite outer ends of the first guide rail 10 and the second guide rail 20 are higher than the connected inner ends, and the first guide rail 10 is provided with a rotating conveying chain 11 above, and the conveying chain 11 is uniformly provided with a push plate 12 to push the pulley on the first guide rail 10 to move along the first guide rail 10.

[0025] The double-track pulley release device comprises a fixed plate 31, a release frame 32 and an elastic member 33, wherein the fixed plate 31 is fixed above the second guide rail 20; the release frame 32 comprises a driving part 321, a connecting rod part 322 and a release part 323 which are sequentially hinged, wherein the driving part 321 and the release part 323 are respectively installed on the fixed plate 31 in a vertical rotatable manner through a first rotating shaft 34 and a second rotating shaft 35, and the second rotating shaft 35 is close to the lower side of the first rotating shaft 34, wherein the release part 323 is in a triangular shape with an opening facing downward, and the release part 323 keeps a predetermined gap with the second guide rail 20 and has a first opening 301 and a second opening 302 in the extension direction of the second guide rail 20, wherein the first opening 301 is close to the first guide rail 10, and correspondingly, the second opening 302 is away from the first guide rail 10, and the pulley 40 gradually moves from the outside of the second opening 302 to the outside of the first opening 301 on the second guide rail 20, and temporarily stays at the position between the second opening 302 and the first opening 301, i.e. the opening position of the triangular shape, wherein the staying time is related to the running speed of the push plate 12 and the distance between adjacent push plates 12, wherein the elastic member 33 is located above the driving part 321 and close to the conveying chain 11 relative to the first rotating shaft 34, and the high end of the elastic member 33 is connected to the fixed plate 31, and the opposite low end of the elastic member 33 is connected to the driving part 321, and the low end is relatively close to the conveying chain 11 or the outside end of the driving part 321;

[0026] In the initial state, the opening size of the first opening 301 is larger than the outer diameter of the pulley 40, and since the second guide rail 20 extends obliquely, the pulley 40 located in the triangular opening can automatically slide out of the first opening 301 on the second guide rail 20 and move to the connection position of the second guide rail 20 and the first guide rail 10, and the opening size of the second opening 302 is smaller than the outer diameter of the pulley 40, so that the subsequent pulley 40 can be blocked from entering the triangular opening position at the second opening 302;

[0027] The driving part 321 is pushed down by the pusher 12 when the conveying chain 11 rotates, and the releasing part 323 is rotated by the connecting rod part 322 to expand the second opening 302, so that the pulley 40 on the second guide rail 20 can enter the triangular opening position. At this time, the opening size of the second opening 302 is expanded by the rotation of the releasing part 323, and based on the principle of lever, the opening size of the first opening 301 is correspondingly reduced, so that the pulley 40 cannot pass through the first opening 301. After the pusher 12 passes the driving part 321, the releasing frame 32 returns to the initial state under the retraction of the elastic member 33, and the pulley 40 in the triangular opening position slides to the connecting position of the first guide rail 10 and the second guide rail 20 through the first opening 301, so as to be pushed by the pusher 12, thereby realizing the intermittent release of the pulley 40.

[0028] The elastic member 33 is a spring.

[0029] Therefore, the double-rail pulley releaser provided by the application can provide release power by means of the conventional circumrotating conveying chain 11 and the pusher 12 on the conveying chain 11. The driving part 321 is pushed down by the pusher 12 when the conveying chain 11 rotates, and the releasing part 323 is rotated by the connecting rod part 322 to expand the second opening 302. After the pusher 12 passes the driving part 321, the releasing frame returns to the initial state under the action of the elastic member 33, and the pulley 40 in the triangular opening position slides out of the releasing frame through the first opening 301, thereby realizing the intermittent release of the pulley 40. The release power is no longer provided by the air cylinder or the electric cylinder, the transfer is more reliable, and the equipment cost can be saved.

[0030] In one embodiment, the fixed plate 31 is an I-shaped steel, and the fixed plate 31 is parallel to the second guide rail 20.

[0031] In one embodiment, the release frame 32 is symmetrically distributed on both sides of the fixed plate 31, and the driving part 321, the connecting rod part 322 and the release part 323 respectively correspond to two driving rods 3211, two connecting rods 3221 and two triangular release plates 3231, wherein two driving rods 3211 are respectively connected vertically at both ends of the first rotating shaft 34, and the outer ends of the two driving rods 3211 are vertically connected with connecting pieces 3212 matched with the dial plate 12, which can ensure that the dial plate 12 accurately drives the driving part 321 during rotation. The connecting piece 3212 can be a connecting plate that can have a larger contact area with the dial plate 12, and the connecting piece 3212 can also be a connecting shaft. Two triangular release plates 3231 are respectively connected vertically on both sides of the second rotating shaft 35, and two triangular release plates 3231 are respectively connected with dial shafts 3232 at the end positions for accurately blocking the pulley 40. The elastic member 33 has two, which are symmetrically connected to two driving rods 3211 and both sides of the fixed plate 31. In this way, the symmetrical distribution of the driving rod 3211, the connecting rod 3221 and the triangular release plate 3231 can make the structure of the release frame more stable, and the connecting piece 3212 can be more stably matched with the dial plate 12 to ensure that the dial plate 12 can accurately drive the driving part 321. The dial shaft 3232 can also be more stably matched with the pulley 40 to ensure that the dial shaft 3232 can accurately block the pulley 40, thereby improving the reliability of the intermittent release of the pulley by the release frame as a whole.

[0032] In one embodiment, the driving rod 3211 is provided with a plurality of positioning holes 303 along the length direction, and the elastic member 33 is connected to the positioning holes 303, so that the initial inclination of the driving part 321 can be flexibly adjusted by adjusting the connection position of the elastic member 33 in different positioning holes 303, thereby blocking pulleys 40 of different outer diameter sizes and having a wider application range.

[0033] In one embodiment, the fixing plate 31 is respectively provided with upper pressing plates 311 and lower pressing plates 312 in parallel at the top and bottom, wherein the upper pressing plates 311 and the lower pressing plates 312 are connected by bolts 313, wherein the high end of the elastic member 33 is connected to the upper pressing plates 311, and the lower pressing plates 312 are provided with a protruding structure for abutting the release end of the triangular release plate 3231, or the nut 314 of the bolt 313 protrudes from the bottom of the lower pressing plates 312 and is opposite to the release end of the triangular release plate 3231, wherein the release end is the end close to the first opening 301, so that the triangular release plate 3231 can be provided with a certain limit by the protruding structure or the nut 314, so that the triangular release plate 3231 can reciprocate within the range between this limit and the position when the lever 12 is separated from the driving rod 3211, and the working stability is better.

[0034] Further preferably, one or a nut (not shown in the figure) is further sleeved on the bolt 313, wherein the nut is between the lower pressing plates 312 and the nut 313, so that the minimum position height of the nut 313, that is, the minimum blocking height of the second opening 302 or the maximum release height of the first opening 301, can be adjusted by adjusting the number of nuts, so as to adapt to release pulleys 40 of different outer diameter sizes.

[0035] It should be noted that the terms "first", "second" in the present application are only for descriptive purposes, and do not represent any order, and cannot be understood as indicating or implying relative importance, and these terms can be interpreted as names.
