Two parallel X-axis moving mechanisms 300 include an X-axis main beam 310 and a second slide 320, and the two ends of the X-axis main beam 310 are fixedly connected with the first slides 240 on both sides.

[0036] The first slide 240 on one side is slidably connected to the Z-axis main beam 210, so that when the first slide 240 drives the X-axis main beam 310 to slide along the Z-axis main beam 210, it can always maintain a straight line sliding along the Z-axis main beam 210 without deviation, and the first slide 240 on the other side is connected to the Z-axis main beam 210 by rolling, and the first slide 240 on the rolling connection side can be slightly offset laterally.

[0037] In this embodiment, the X-axis main beam 310 and the first slide 240 are connected via a connecting assembly 120, and the connecting assembly 120 includes a connecting plate 122 and a connecting member 121.

By setting the connecting assembly 120, the assembly connection between the X-axis main beam 310 and the first slide 240 is more convenient, the assembly speed is improved, and the connection is more stable.

[0038] In this embodiment, a rack 170 is installed on the first surface 211 of the Z-axis main beam 210, and the Z-axis moving mechanism also includes a first driving mechanism 220, the first driving mechanism 220 includes a first driving motor 221 and a first transmission gear 225, the first transmission gear 225 is engaged with the rack 170 on the first surface 211, the first driving motor 221 is fixedly connected to the X-axis main beam 310, and the first driving motor 221 is located at the central position of the length direction of the X-axis main beam 310, the The output shaft of the first drive motor 221 is connected to the steering gear 222, and both ends of the steering gear 222 are connected to the first transmission gear 225 through a transmission connecting rod 223. The transmission connecting rod 223 and the first transmission gear 225 are connected through a coupling 224. Through the setting of the first drive mechanism 220, a first drive motor 221 set on the X-axis main beam 310 can drive the first slide 240 on both sides of the X-axis main beam 310 to slide along the Z-axis main beam 210 at the same time, which saves space and is more energy-efficient.

[0039] In this embodiment, a wheel cover 231 is provided on the roller 232, and the wheel cover 231 is fixedly connected to the first slide seat 240. A protrusion 2311 is provided on the side of the wheel cover 231 abutting against the guide rail 110. A V-shaped groove is provided on the guide rail 110, and the protrusion 2311 extends into the V-shaped groove to limit the wheel cover 231 from falling off the guide rail 110. In order to maintain stability during long-distance operation, the protrusion 2311 provided on the wheel cover 231 is deeply inserted into the V-shaped groove. In this way, when the roller 232 rolls relative to the Z-axis main beam 210, when the roller 232 is slightly offset laterally relative to the Z-axis main beam 210, the protrusion 2311 extending into the V-shaped groove can limit the offset range of the roller 232 relative to the Z-axis main beam 210, thereby improving safety during operation.

[0041] In this embodiment, end plates 130 are installed at both ends along the length direction of the Z-axis main beam 210, and elastic members 140 are installed on the opposite sides of the end plates 130. The first slide 240 stops sliding after abutting against the elastic member 140. When the first slide 240 slides along the Z-axis main beam 210, when it slides to the two ends of the Z-axis main beam 210, the elastic members 140 at both ends will abut against the first slide 240 to avoid rigid pauses, which will cause the first slide 240 to stop slowly, reducing the vibration caused to the Z-axis main beam 210 or other structures in the hoisting and transportation device 100, avoiding damage to each structural component therein, and extending the service life of the hoisting and transportation device 100.

[0042] In this embodiment, a felt block 233 is also installed in the wheel cover 231. The felt block 233 is arranged on both sides of the rotation direction of the roller 232. The felt block 233 is in contact with the guide rail 110. When the first slide seat 240 runs relative to the Z-axis main beam 210, dust is easily scattered on the guide rail 110. By setting the felt block 233, the dust on the guide rail 110 can be effectively removed, reducing the number of maintenance times.

The second driving motor 330 rotates to drive the second transmission gear to rotate, thereby realizing the sliding of the second slide 320 relative to the X-axis main beam 310.

[0045] In this embodiment, an elastic member 140 is installed on the side of the first slide 240 facing the second slide 320 to abut against the second slide 320 to avoid rigid contact between the second slide 320 and the first slide 240 during operation, thereby improving the protection of various structures in the lifting and transportation device 100.

Through the third driving mechanism, the Y-axis main beam 410 is driven to reciprocate in the vertical direction to drive the hoisted transport items to move up and down. In addition, by sliding the Y-axis main beam 410 relative to the Y-axis fixed seat 420, there is no constraint on the shape of the hoisted items, thereby improving the applicability of the hoisting and transportation device 100.

[0048] Furthermore, a lubrication device 160 is installed on the first slide 240, the second slide 320 and the Y-axis fixed seat 420.

[0050] In summary, the hoisting and transporting device 100 of the present invention is slidably connected to the Z-axis main beam 210 through the first slide 240 on one side, so that when the first slide 240 drives the X-axis main beam 310 to slide along the Z-axis main beam 210, it can always maintain a straight line sliding along the Z-axis main beam 210 without deviation, and the first slide 240 on the other side is connected to the Z-axis main beam 210 by rolling, and the first slide 240 on the rolling connection side can be slightly offset laterally, so that when sliding, the first slide 240 on the rolling connection side will As the position of the first slide 240 on one side of the sliding connection is slightly offset, the first slides 240 on both sides of the X-axis main beam 310 are kept on a consistent travel route.
