AI Technical Summary
During the use of traditional vertical tail plates, if the chain breaks, the goods will immediately fall vertically, which poses a major risk of safety accidents, especially when the goods are too large or too heavy, the chain is insufficient to withstand the capacity, resulting in serious accidents.
A chain-type vertical tail plate fall-off preventing device is designed, including column components, lifting arms, safety devices, large plates and chain transmission systems. Using the combination of safety buckle, torsion spring and wire rope, through the action of the limit groove and torsion spring, when the chain breaks, the safety buckle instantly snaps into the limit groove to prevent the large plate from falling.
It effectively prevents the vertical fall of the goods, protects the safety of the goods and operators, and avoids safety accidents caused by overload.

Description
Technical Field
[0001] The utility model relates to the technical field of safety protection, and particularly relates to a chain-type vertical tailboard anti-falling device. Background Technique
[0002] During the use of traditional vertical tailboards, since the lifting arms and the board surface move up and down along the vertical rails, which is different from the lifting arms of cantilever tailboards that only make rotational movements, if the chain breaks accidentally, the large board together with the goods will immediately fall vertically, thus causing major accidents and economic losses.
[0003] At the same time, when using traditional vertical tailboards without anti-falling devices, there are certain dangers in operation, and if the goods are too large or too heavy and exceed the bearing capacity of the chain, major safety accidents will be triggered.
[0004] Therefore, we propose a chain-type vertical tailboard anti-falling device to solve the above problems. Content of the Utility Model
[0005] In view of the problems existing in the existing chain-type vertical tailboard anti-falling device, the present utility model is proposed.
[0006] Therefore, the purpose of the present utility model is to provide a chain-type vertical tailboard anti-falling device, which solves the problems of traditional vertical tailboards without anti-falling devices, such as dangerous operation, and if the goods are too large or too heavy and exceed the bearing capacity of the chain, major safety accidents will be triggered.
[0007] In order to achieve the above purpose, the present utility model provides the following technical solutions:
[0008] A chain-type vertical tailboard anti-falling device includes a column assembly, a lifting arm, a safety device, a large board and a chain drive system. The lifting arm includes a rib plate, a chain mounting plate and a large board connecting support. The lifting arm is slidably connected to the inner guide rail of the column assembly and is arranged in the guide rail cavity of the column assembly. The root of the large board is hinged to the lower end of the lifting arm and is arranged in cooperation with the large board connecting support. A notch is opened at the upper end inside the rib plate, and the safety device is arranged in the notch.
[0009] Preferably, the safety device includes a safety buckle mounting plate, a safety buckle, a torsion spring and a steel wire rope. A support shaft is fixedly arranged on the side of the safety buckle mounting plate. The safety buckle is rotatably sleeved on the support shaft. The torsion spring is sleeved outside the support shaft, and both ends are fixedly connected to the support shaft and the safety buckle respectively. The steel wire rope is fixedly arranged between the safety buckle and the chain drive system.
[0010] Preferably, the column assembly includes a front column, a rear column and a side plate. A plurality of spaced limiting grooves are formed in the side of the front column, and the lower end of the safety buckle is arranged in cooperation with the limiting grooves.
[0011] Preferably, a through hole for fixing and passing through the wire rope is formed at the lower end inside the safety buckle.

Detailed implementation manners
[0025] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.
[0026] An embodiment of the present invention discloses a chain-type vertical tailgate anti-falling device.
[0027] Embodiment 1
[0028] The present invention provides a chain-type vertical tailgate anti-falling device as shown in Figures 1-5 which includes a column assembly 1, a lifting arm 2, a safety device 3, a large plate 4 and a chain drive system 5. The column assembly 1 includes a front column 1-1, a rear column 1-2 and a side plate 1-3. A plurality of spaced limit grooves 6 are provided on the side of the front column 1-1. The lower end of the safety buckle 3-2 is cooperatively arranged with the limit groove 6. The lifting arm 2 includes a rib plate 2-1, a chain mounting plate 2-2 and a large plate connection support 2-3. The lifting arm 2 is slidably connected to the internal guide rail of the column assembly 1 and is arranged in the guide rail cavity of the column assembly 1. The root of the large plate 4 is hinged to the lower end of the lifting arm 2 and is cooperatively arranged with the large plate connection support 2-3. A notch is provided at the upper end inside the rib plate 2-1. The safety device 3 is arranged in the notch. The safety device 3 includes a safety buckle mounting plate 3-1, a safety buckle 3-2, a torsion spring 3-3 and a steel wire rope 3-4. Both ends inside the safety device 3 are fixedly arranged by screwing with the rib plate 2-1 through mounting bolts.
[0029] During lifting, the lifting arm 2 moves up and down in the guide rail of the column assembly 1. At the same time, the steel wire rope 3-4 is fixedly attached to one end of the safety buckle 3-2. The safety buckle 3-2 and the lifting arm 2 lift and lower together. When the large plate 4 is at a high position, under normal conditions, the safety buckle 3-2 remains in a fitting state and does not affect the normal operation of the vertical tailgate. When the large plate 4 is overloaded, the chain in the chain drive mechanism 5 will break under overload. At this time, the large plate 4 will fall freely with the goods, and the steel wire rope 3-4 will immediately lose the tension on the safety buckle 3-2, causing the torsion spring 3-3 to stretch at the same time, making the safety buckle 3-2 stretch to the horizontal and get stuck in the limit groove 6 of the column 1, so that the large plate 4 immediately stops falling and protects the safety of the goods.
[0030] Embodiment 2
[0031] Embodiment 2 is based on Embodiment 1 as Figure 1 and Figure 5 shown. A support shaft 3-5 is fixedly provided on the side of the safety buckle mounting plate 3-1. The safety buckle 3-2 is rotatably sleeved on the support shaft 3-5. A torsion spring 3-3 is sleeved outside the support shaft 3-5, and both ends are fixedly connected to the support shaft 3-5 and the safety buckle 3-2 respectively. A rotation hole for cooperating with the rotation of the support shaft 3-5 is formed inside the safety buckle 3-2. A steel wire rope 3-4 is fixedly arranged between the safety buckle 3-2 and the chain drive system 5. A through hole for fixedly passing through the steel wire rope 3-4 is formed at the lower end inside the safety buckle 3-2.
[0032] When the lifting arm 2 stably moves upward, at this time, under the connection of the steel wire rope 3-4, the mounting buckle 3-2 rotates under the pulling of the steel wire rope 3-4. At this time, the torsion spring 3-4 is twisted, and the position of the safety buckle 3-2 can be determined, so that the safety buckle 3-2 will not affect the movement of the lifting arm 2 when the lifting arm 2 moves longitudinally. At the same time, after the steel wire rope 3-4 breaks, the safety buckle 3-2 can be quickly rebounded by the resilience of the torsion spring 3-3 and can be inserted into the limiting groove 6.
[0033] Only some exemplary embodiments of the present invention have been described by way of illustration above. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present invention, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
