[0033] In this embodiment, in order to further improve the anti-pulling effect, the door machine cable anti-bending guide device is also provided with a guide mechanism 4, which includes a guide seat body 421 and a guide component 42. The guide component 42 is used to adjust the angle of the cable 1 to reduce the pulling strength of the cable 1 to prevent the cable 1 from being damaged.

[0034] Specifically, the guide assembly 42 includes a guide tube 422 and a guide seat body 421. The guide tube 422 is rotatably arranged relative to the guide seat body 421. When the door machine 10 moves, the cable 1 reel above the door machine 10 will retract or release the cable 1. When the door machine 10 runs to the right side of the working electrical box 2, the guide tube 422 will rotate 180 degrees due to the force of retracting and releasing the cable 1. The guide seat body 421 includes an input end 4211 and an output end 4212. The guide tube 422 extends from the input end 4211 to the output end 4212.

By clamping the fixed block 4223 on the fixed groove 4213 provided on the guide seat body 421, a stable movable connection is formed between the guide tube 422 and the guide seat body 421. The guide tube 422 is rotatably set on the fixed groove 4213 of the wire seat body 421 through the fixed block 4223. In this embodiment, the fixed block 4223 is preferably set to a ring shape. When the door machine 10 moves, the cable 1 is passively pulled and rotated, and the guide tube 422 rotates inside the guide seat body 421 to reduce damage to the cable 1 during the pulling process.

[0036] Specifically, the guide tube 422 includes a straight tube portion 4221 and a curved tube portion 4222. The curved tube portion 4222 is arranged at the outlet end 4212 of the guide seat body 421. The curved tube portion 4222 is used to further enhance the anti-pull effect. When the door machine 10 moves and changes its position, since the guide tube 422 and the guide seat body 421 are movably connected, the curved tube portion 4222 can drive the cable 1 to rotate within a range of 180 degrees, thereby further reducing the excessive pulling damage to the cable 1 caused by the movement of the door machine 10 for position change.

[0037] In this embodiment, a locking assembly 4214 is provided on the guide seat body 421, which is arranged on the upper box body 421A and the lower box body 421B of the guide seat body 421.

The lock buckle includes a buckling part 42141 and a locking part 42142. When the buckling part 42141 and the locking part 42142 are combined, they are fixed by a threaded connection. Other conventional components used for unlocking or locking can be used as replacement examples, such as installing a hook or a bolt on the guide seat body 421 as the locking assembly 4214.

[0038] In this embodiment, the guide base 41 includes at least one guide base fixing hole 411, at least one guide base fixing hole 411 is provided, and is fixed to the ground using a guide base expansion screw 412. The embodiment of the guide base 41 is replaced with reference to the setting of the anti-pull base 31 below, which will not be elaborated here, for example, by pre-embedded fixation with bolts or steel bars.

[0039] In this embodiment, the clamp 32 is sleeved on the cable 1 to prevent pulling and enhance the stability of the cable 1 when the door machine 10 moves.

[0040] Specifically, the connecting mechanism 323 on the clamp 32 includes a connecting plate 3231 and a screw hole 3232. The screw hole 3232 is set on the connecting plate 3231. The first clamp sleeve 321 and the second clamp sleeve 322 are connected by driving a screw 3233 into the screw hole 3232 on the connecting plate 3231 to form a threaded connection. In this embodiment, the connecting mechanism 323 adopts the connecting plate 3231 and the screw hole 3232 for convenience. In actual production and use replacement examples, the connecting mechanism 323 can adopt a lock, a pin, a bolt or the like to fix the clamp 32, ultimately for the purpose of enhancing the stability of the sleeve.

[0041] Specifically, a connecting mechanism 323 is preferably provided on both sides of the clamp 32. When the gantry crane 10 drags the cable 1, the connecting mechanisms 323 on both sides of the clamp 32 can be subjected to force. Therefore, the connection mechanisms 323 are arranged on both sides of the clamp 32, which is conducive to enhancing the stability of the clamp 32.

[0042] In this embodiment, the connecting member 33 is preferably a chain, one end of the chain is welded to the clamp 32, and the connecting portion 34 at the other end is fixed to the positioning portion 311. The positioning portion 311 is used in conjunction with a shackle as a preferred example to fix the chain. The shackle and the connecting portion 34 opened on the chain, that is, the chain link are connected. Compared with other industrial linear components, the chain has better stability. The connecting portion 34 preferably uses a chain link for easy buckling. The connecting portion 34 can also be suitable for lock, threaded connection and other methods. Other connecting members 33 that can be used to connect the clamp 32 and the positioning portion 311 used in conjunction can be implemented as alternative examples, such as wire rope, stranded wire, etc., which are welded and fixed.

[0043] In this embodiment, the fixing part 312 is provided with an anti-pull base fixing hole 3121, and at least one anti-pull base fixing hole 3121 is provided. The anti-pull base expansion screw 3122 is installed in the anti-pull base fixing hole 3121 for fixing. For the convenience of component maintenance and simple installation, this embodiment uses the anti-pull base fixing hole 3121 in combination with the anti-pull base expansion screw 3122 as the fixing part 312. As a preferred example, the anti-pull base expansion screw 3122 has the characteristic of being more convenient to install and disassemble. In a specific replacement example, the embedded parts can be used as a replacement, such as setting bolts and steel bars in the anti-pull base 31 and pre-embedding them in the ground.

[0044] The following content serves as an explanation of the working principle of this utility model:

[0045] 1. The present invention adds a clamp 32 on the basis of the existing technology. When in use, the clamp 32 is sleeved on the cable 1. The clamp 32 is connected to the anti-pull base 31 through a connector 33. The connector 33 uses a chain to cooperate with the shackle of the positioning part 311 to facilitate the release of the device. The anti-pull device thus provided has a good anti-pull effect, and the cable 1 is more stable when being dragged. Secondly, since a chain is used to replace the nylon strap of the existing technology, the anti-pull effect will be further enhanced.

[0046] 2. In order to further enhance the anti-pull effect, the present invention is provided with a guide mechanism 4, which includes a guide assembly 42 and a guide base 41. The guide assembly 42 includes a guide tube 422 and a guide seat body 421. The direction or angle of the cable 1 is adjusted to conform to the movement of the door machine 10 to reduce the impact of pulling on the cable 1. Specifically, the guide tube 422 is installed inside with the guide seat body 421 as a fixed point, and the interior is connected by a fixed block 4223. The guide tube 422 is rotatably connected in the guide seat body 421. When the door machine 10 moves, the cable 1 moves along the guide tube 422, thereby achieving the anti-drag effect.

[0047] 3. The guide tube 422 is preferably provided with a bend 4222. When the bend 4222 is installed, the door machine 10 moves to the opposite side, and the bend 4222 can drive the cable 1 to rotate 180 degrees, effectively preventing the door machine 10 from being pulled. In actual use, the bend 4222 can drive the cable 1 to rotate within a range of 180 degrees to meet the needs of different production operations, such as Figure 1 location, Figure 1 The door machine 10 is located in front of the working electric box 2. When the door machine 10 moves to the rear of the working electric box 2, the curved pipe portion 4222 moves from Figure 1 The state is counterclockwise, that is, to the left, rotated 180 degrees toward the working electric box 2, and the cable 1 moves along the bend 4222 to achieve the effect of anti-pull; when the door machine 10 is in Figure 7 position, the door machine 10 moves to the position of the working electrical box 2, the bend 4222 rotates 180 degrees clockwise, that is, to the right, toward the working electrical box 2, and the cable 1 moves with the bend 4222 to achieve an anti-pull effect.

[0048] 4. In addition, before using the utility model, the cable 1 is covered with rubber.

[0049] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention.
