[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] A mobile gantry for a gantry milling machine, such as Figure 1-Figure 3 As shown, it includes a slide rail 1, a slider 11 is slidably installed on the inner wall of the slide rail 1, a gantry body 12 is fixedly installed on the top of the slider 11, a hook 13 is fixedly installed on the center end of the gantry body 12, a moving device 2 is provided at the front and rear ends of the slide rail 1, and a fixing device 3 is provided on the outside of the slide rail 1. The moving device 2 includes a mounting block 21, a slide column 22 and a universal wheel 23. The mounting block 21 is fixedly installed on the outer wall of both ends of the slide rail 1. The number of the mounting blocks 21 is several, and the slide column 22 is penetrated and slidably installed on the top of the mounting block 21. The inner wall of the slide column 22 is provided with a cavity, and the side wall of the slide column 22 is provided with a slot. When the gantry body 12 is needed, the slide column 22 is pressed down, and the universal wheel 23 is fixedly installed at the bottom of the slide column 22. The slide column 22 drives the universal wheel 23 to move downward on the inner wall of the mounting block 21, and the universal wheel 23 is adjusted to the working state and moved to the hoisting area of the gantry milling machine. Through the setting of the universal wheel 23, not only the mobility of the gantry body 12 is enhanced, but also its stability and adaptability under different working conditions are improved.

[0026] The moving device 2 also includes a knob 24, a rotating rod 25, a concave disk 26, a card plate 27, a connecting plate 28 and a spring 29. The rotating rod 25 passes through and is rotatably installed on the top of the sliding column 22. The knob 24 is fixedly installed on the top of the rotating rod 25. When the gantry body 12 uses the hook 13 to hoist objects, the overall vibration will cause the sliding column 22 to move, affecting the gantry body 12. At this time, after moving it to the hoisting area of the gantry milling machine, the knob 24 is rotated, and the knob 24 drives the rotating rod 25 to rotate. The concave disk 26 is fixedly installed on the bottom of the rotating rod 25, and the rotating rod 25 drives the concave disk 26 to rotate. The concave disk 26 is provided with two concave surfaces. The card plate 27 is slidably installed on the inner wall of the card slot of the sliding column 22. The card plate 27 is close to one side of the concave disk 26. The side is an arc-shaped surface, and the card plate 27 is located on the movement trajectory of the concave disk 26. The convex surface of the concave disk 26 will contact the arc-shaped surface of the card plate 27, so that the card plate 27 slides outward on the inner wall of the slot of the slide column 22. The connecting plate 28 is fixedly installed on the top of the card plate 27 away from the slot of the slide column 22. The spring 29 is fixedly installed on the side of the connecting plate 28 away from the concave disk 26. The card plate 27 will be stuck between the slot of the slide column 22 and the mounting block 21. When the universal wheel 23 is not needed, it is only necessary to rotate the knob 24 in the opposite direction. The card plate 27 will be reset due to the spring 29 on the connecting plate 28. The setting of the card plate 27 effectively prevents the displacement of the slide column 22 due to vibration when hoisting objects, thereby ensuring the stability and safety of the gantry body 12.

[0027] When the mobile gantry for a gantry milling machine of the present invention is in use, when the gantry main body 12 is needed, the slide column 22 is pressed downward, and the slide column 22 drives the universal wheel 23 to move downward on the inner wall of the mounting block 21, and the universal wheel 23 is adjusted to a working state and moved to the hoisting area of the gantry milling machine. The setting of the universal wheel 23 not only enhances the mobility of the gantry main body 12, but also improves its stability and adaptability under different working conditions.

[0028] The spring 29 on the connecting plate 28 resets the card plate 27, and the arrangement of the card plate 27 effectively prevents the displacement of the slide column 22 caused by vibration when hoisting objects, thereby ensuring the stability and safety of the gantry frame body 12.

[0030] like Figure 4 As shown, the fixing device 3 includes a rotating shaft frame 1 31, a vertical plate 32, a rotating shaft frame 2 33 and a support plate 34. The rotating shaft frame 1 31 is fixedly mounted on the outer wall of the bottom end of the mounting block 21 away from the gantry body 12, the vertical plate 32 is rotatably mounted on the inner wall of the rotating shaft frame 1 31, and a square groove is opened on the top of the vertical plate 32. The rotating shaft frame 2 33 is fixedly mounted on the outer wall of the top end of the mounting block 21 away from the gantry body 12, and the support plate 34 is rotatably mounted on the inner wall of the rotating shaft frame 2 33. The support plate 34 is located on the vertical plate 3 2. On the motion trajectory of the square groove, when the moving device 2 is not needed, the vertical plate 32 is rotated ninety degrees with the rotating shaft frame 1 31 as the center, and the support plate 34 is rotated with the rotating shaft frame 2 33 as the center, and inserted into the square groove of the vertical plate 32. When the universal wheel 23 is folded upward, the vertical plate 32 provides stable support for the gantry body 12, which not only enhances the stability of the equipment under static working conditions, but also reduces the risk of displacement caused by vibration or external force, ensuring the accuracy and safety of the processing process.

[0031] The fixing device 3 also includes a fixing plate 35, a connecting rod 36, an L-shaped mounting plate 37, an inverted E-shaped pin 38, an insertion rod 3801, an outer column 39 and a connecting column 310. The fixing plate 35 is fixedly mounted on the side wall of the vertical plate 32 away from the hook 13, the connecting rod 36 is fixedly mounted on the outer wall of the fixing plate 35 away from the hook 13, the L-shaped mounting plate 37 is fixedly mounted on the outer wall of the slide rail 1 away from the hook 13, the outer column 39 is fixedly mounted on the side wall of the L-shaped mounting plate 37, the center end of the inverted E-shaped pin 38 passes through and is slidably mounted on the top of the L-shaped mounting plate 37, the insertion rod 3801 is fixedly mounted on the bottom of both ends of the inverted E-shaped pin 38, the connecting column 310 is slidably mounted on the inner wall of the outer column 39, the connecting column 310 is provided with a socket at one end close to the L-shaped mounting plate 37, and the connecting column 310 is provided with a slot at one end close to the connecting rod 36, and the connecting rod 36 is located at the connecting column 3 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310, so that the support plate 310 is fixed to the support plate 310, and the support plate 310 is fixed to the support plate 310,

[0032] When the mobile gantry for a gantry milling machine of the present invention is in use, when the moving device 2 is not needed, the vertical plate 32 is rotated ninety degrees with the rotating shaft frame 1 31 as the center, and the support plate 34 is rotated with the rotating shaft frame 2 33 as the center, and inserted into the square groove of the vertical plate 32.

[0033] When the vertical plate 32 rotates, the vertical plate 32 drives the fixed plate 35 to rotate, and the fixed plate 35 drives the connecting rod 36 to rotate. After the connecting rod 36 is placed in the horizontal direction, the connecting column 310 slides outward. After the socket on the connecting column 310 moves forward, the slot on the connecting column 310 will insert one end of the connecting rod 36 into the inner wall of the slot on the connecting column 310. At the same time, the insertion rod 3801 on the inverted E-shaped pin 38 releases the downward restriction, and the insertion rod 3801 is inserted into the socket on the connecting column 310. The insertion rod 3801 will fix the connecting column 310 and the outer column 39 together, thereby improving the stability of the vertical plate 32 and providing a dispersion effect for the supporting force of the support plate 34, preventing the support plate 34 from breaking when unilaterally supporting the gantry body 12, further enhancing the rigidity and vibration resistance of the structure.
