Anti-falling mechanism for light stacker in lithium battery storage

Abstract

The present invention discloses a fall prevention mechanism for a light stacker in a lithium battery storage library, which solves the problem of how to set up a simple and reliable mechanical fall prevention mechanism for the light stacker. A compression spring is arranged on the suspension rod connected to the traction steel wire rope of the load platform. The breaking action of the traction steel wire rope of the load platform is used as the source power to induce the release of the compression spring, and the pressure released by the compression spring is used as the triggering force for the active swing arm to swing. The active swing arm and the driven swing arm are engaged by gears. When the compression spring triggers the active swing arm to swing, the active swing arm drives the driven swing arm to swing through the engaged gears, so that the wedge blocks on the active swing arm and the driven swing arm swing with the two swing arms, forming a clamping force on the column of the stacker, thereby playing a role in preventing falling; on the premise of broken rope, it reliably and effectively prevents the load platform from falling.

Description

Technical Field

[0001] The present invention relates to a mechanical anti-falling device, and particularly to an anti-falling mechanism used for a light stacker in a lithium battery storage. Background Art

[0002] Lithium battery storage is generally a production-in-line storage. The stacker used for handling goods in the storage is generally a light double-column stacker. Since it is a production-in-line storage, the overall height of the storage is generally relatively low. The goods handled are finished or semi-finished lithium batteries. The load capacity of the stacker's load platform is relatively light, generally about 100 kg, and the overall shape of the handling stacker is relatively small. Currently, the load platforms of light double-column stackers are all in the form of using steel ropes to suspend through fixed pulleys at the single hanging points on both sides of the load platform. The hanging point positions are directly fixedly connected to the load platform. Generally, no mechanical anti-falling device is provided, but the anti-falling function is set electrically through an electrical module. There is a defect of the blank of mechanical anti-falling for the load platform. How to set up a simple and reliable mechanical anti-falling mechanism has become a problem to be solved on-site. Summary of the Invention

[0003] The present invention provides an anti-falling mechanism for a light stacker in a lithium battery storage, and solves the technical problem of how to set up a simple and reliable mechanical anti-falling mechanism for a light stacker.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The general idea of the present invention is: on the suspension rod connected to the traction steel rope of the load platform, a compression spring is set. The breaking action of the traction steel rope of the load platform is used as the source power to induce the release of the compression spring. The pressure released by the compression spring is used as the triggering force for the active swing arm to swing. The active swing arm and the driven swing arm are meshed through gears. The compression spring triggers the active swing arm to swing. The active swing arm makes the driven swing arm swing through the meshed gears, so that the wedge blocks on the active swing arm and the wedge blocks on the driven swing arm swing with the two swing arms, forming a clamping of the stacker column, thereby playing a role in preventing falling.

[0006] A fall prevention device for a light stacker in a lithium battery library, comprising a left column of the stacker, a right column of the stacker, and a load platform of the stacker. On the load platform of the stacker, a left hanger and a right hanger are respectively and fixedly arranged. On the load platform of the stacker, a left traction steel wire rope of the load platform and a right traction steel wire rope of the load platform are respectively connected. The lower end of the left traction steel wire rope of the load platform is connected to a left suspension rod. The lower end of the left suspension rod is connected to the left hanger through a left suspension rod connection pin. The lower end of the right traction steel wire rope of the load platform is connected to a right suspension rod. The lower end of the right suspension rod is connected to the right hanger through a right suspension rod connection pin. At the lower end of the left suspension rod, a spring bottom limiting step of the suspension rod is arranged. On the outer vertical surface of the left hanger directly above the spring bottom limiting step of the suspension rod, a spring upper limiting plate is fixedly arranged. A through hole for the left suspension rod to pass through is arranged on the spring upper limiting plate. The left suspension rod is movably inserted through the through hole for the left suspension rod to pass through. A spring is arranged between the spring upper limiting plate and the spring bottom limiting step of the suspension rod; on the outer vertical surface of the left hanger, a left rear pin shaft and a left front pin shaft are respectively arranged. The left rear pin shaft is arranged at the rear side of the left column of the stacker, and the left front pin shaft is arranged at the front side of the left column of the stacker. A left rear swing arm is hinged on the left rear pin shaft, and a left front swing arm is hinged on the left front pin shaft. Outer teeth at the front end of the left rear swing arm are arranged at the front end side of the left rear swing arm, and outer teeth at the rear end of the left front swing arm are arranged at the rear end side of the left front swing arm. The outer teeth at the front end of the left rear swing arm are engaged with the outer teeth at the rear end of the left front swing arm. At the rear end of the left outer side surface of the left rear swing arm, a left rear locking wedge block is fixedly arranged. A left rear anti-fall gap is arranged between the left rear locking wedge block and the rear vertical surface of the left column of the stacker. At the front end of the left outer side surface of the left front swing arm, a left front locking wedge block is fixedly arranged. A left front anti-fall gap is arranged between the left front locking wedge block and the front vertical surface of the left column of the stacker.

[0007] Side guide wheels are arranged on the front and rear vertical surfaces of the left column of the stacker.

[0008] The present invention is a rotary wedge locking device designed and added based on the fact that there is no mechanical fall prevention device on the load platform of the light stacker used in the current lithium battery project. This device is installed on the hangers on both sides of the load platform of the light stacker. When the equipment is in normal use, since the lifting steel wire rope is subjected to tension, the steel wire rope will open this rotary wedge locking device. When the equipment has a broken rope or serious rope loosening situation, this rotary wedge locking device will rotate under the action of its own spring. After rotation, the wedge block will lock the load platform on the column to prevent the load platform from continuing to fall. Description of the Drawings

[0013] The present invention will be described in detail below with reference to the accompanying drawings:

[0014] A light-duty stacker anti-falling device for a lithium battery storage includes a stacker left column 1, a stacker right column 22, and a stacker loading platform 2. On the stacker loading platform 2, a left hanger 5 and a right hanger 24 are respectively fixedly arranged. On the stacker loading platform 2, a left-side traction steel wire rope 3 of the loading platform and a right-side traction steel wire rope 23 of the loading platform are respectively connected. The lower end of the left-side traction steel wire rope 3 of the loading platform is connected to a left suspension rod 17. The lower end of the left suspension rod 17 is connected to the left hanger 5 through a left suspension rod connection pin 16. The lower end of the right-side traction steel wire rope 23 of the loading platform is connected to a right suspension rod. The lower end of the right suspension rod is connected to the right hanger through a right suspension rod connection pin. At the lower end of the left suspension rod 17, a spring bottom limiting step 18 of the suspension rod is provided. On the outer vertical surface of the left hanger 5 directly above the spring bottom limiting step 18 of the suspension rod, a spring upper limiting plate 19 is fixedly arranged. On the spring upper limiting plate 19, a through hole 20 for the left suspension rod to pass through is provided. The left suspension rod 17 is movably inserted through the through hole 20 for the left suspension rod to pass through. A compression spring 21 is arranged between the spring upper limiting plate 19 and the spring bottom limiting step 18 of the suspension rod; on the outer vertical surface of the left hanger 5, a left rear pin shaft 6 and a left front pin shaft 9 are respectively arranged. The left rear pin shaft 6 is arranged at the rear side of the stacker left column 1, and the left front pin shaft 9 is arranged at the front side of the stacker left column 1. A left rear swing arm 7 is hinged on the left rear pin shaft 6, and a left front swing arm 10 is hinged on the left front pin shaft 9. On the front side end of the left rear swing arm 7, an external tooth at the front end of the left rear swing arm 8 is provided. On the rear side end of the left front swing arm 10, an external tooth at the rear end of the left front swing arm 11 is provided. The external tooth at the front end of the left rear swing arm 8 is engaged with the external tooth at the rear end of the left front swing arm 11. On the rear end of the left outer side surface of the left rear swing arm 7, a left rear locking wedge block 12 is fixedly arranged. Between the left rear locking wedge block 12 and the rear vertical surface of the stacker left column 1, a left rear anti-falling gap 14 is provided. On the front end of the left outer side surface of the left front swing arm 10, a left front locking wedge block 13 is fixedly arranged. Between the left front locking wedge block 13 and the front vertical surface of the stacker left column 1, a left front anti-falling gap 15 is provided; between the stacker right column 22 and the right hanger 24, an anti-falling mechanism having the same structure as that between the above-mentioned stacker left column 1 and the left hanger 5 is also provided.

[0015] Side guide wheels 4 are arranged on the front and rear vertical surfaces of the stacker left column 1; side guide wheels 4 are arranged on the front and rear vertical surfaces of the stacker right column 22.

[0016] When the stacker is in normal use, the traction steel wire rope 3 on the left side of the load platform pulls up the left suspension rod 17. The spring limit step 18 at the bottom of the suspension rod and the upper spring limit plate 19 compress the compression spring 21. At this time, the left front swing arm 10 hinged to the outer vertical surface of the left hanger 5 through the left front pin shaft 9 is in a state of rotating counterclockwise and is in a horizontal state. A left front anti-falling gap 15 is provided between the left front locking wedge block 13 fixedly arranged at the front end of the left outer side surface of the left front swing arm 10 and the front vertical surface of the left column 1 of the stacker; the left rear swing arm 7 hinged to the outer vertical surface of the left hanger 5 through the left rear pin shaft 6 is also in a horizontal state, and the outer teeth 8 at the front end of the left rear swing arm 7 mesh with the outer teeth 11 at the rear end of the left front swing arm 10. The left rear swing arm 7 is in a state of rotating clockwise. A left rear anti-falling gap 14 is provided between the left rear locking wedge block 12 and the rear vertical surface of the left column 1 of the stacker; the gaps generated between the two wedge blocks and the column at this time maintain the normal lifting and use of the load platform 2 of the stacker relative to the two columns.

[0017] When the traction steel wire rope 3 on the left side of the load platform breaks, the pulling force of the traction steel wire rope 3 on the left side of the load platform pulling up the left suspension rod 17 disappears, and the compression force of the compression spring 21 also disappears simultaneously. The pressure released by the compression spring 21 acts on the front end of the left front swing arm 10. The left front swing arm 10 rotates clockwise around the left front pin shaft 9. The left front swing arm 10 meshes with the outer teeth 8 at the front end of the left rear swing arm through the outer teeth 11 at the rear end of the left front swing arm, causing the left rear swing arm 7 to rotate counterclockwise. The simultaneous rotation of the left front swing arm 10 and the left rear swing arm 7 causes the left rear anti-falling gap 14 and the left front anti-falling gap 15 to disappear. The left rear locking wedge block 12 contacts and clamps with the rear vertical surface of the left column 1 of the stacker, and the left front locking wedge block 13 contacts and clamps with the front vertical surface of the left column 1 of the stacker, thereby achieving the effect that the left front swing arm 10 and the left rear swing arm 7 clamp the left column 1 of the stacker; at the same time, the locking mechanism provided between the right column 22 and the right hanger 24 of the stacker also acts, achieving the effect of clamping the right column 22 of the stacker. Eventually, when the load platform 2 of the stacker loses the traction of the steel wire rope, it is locked on the columns of the stacker, preventing it from falling.
