DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0035] Example 1

[0036] like Figure 1-3 As shown, the multifunctional mold turning and lifting machine provided by the utility model includes a crane body 1, a lifting mechanism 15 running above the crane body 1, an upper lifting belt 2 is arranged below the lifting mechanism 15, the upper lifting belt can also be made of or wire rope, and the telescopic frame 3 is connected below the upper lifting belt 2 to realize the lifting of the telescopic frame 3 by the crane, and a trolley running mechanism 16 is arranged on the crane body 1, and the trolley running mechanism 16 is used for the walking drive of the crane body 1. A transmission mechanism 13, a guide device 12 and a telescopic frame hook 4 are arranged on the upper part of the telescopic frame 3. The transmission mechanism 13 can adopt a hydraulic push rod or an electric push rod. If a hydraulic push rod is used for driving, the hydraulic system 7 of the hydraulic push rod is installed on the upper part of the telescopic frame 3 to provide power. The transmission mechanism 13 can also adopt a structure of screw drive, gear rack drive, and chain drive. A flip drive device 5 is installed at the lower part of both ends of the telescopic frame 3. The flip drive device 5 cooperates with the flip platform 6. The flip drive device 5 can be moved on the telescopic frame 3 through the transmission mechanism 13. The two groups of flip drive devices 5 move toward the middle of the telescopic frame 3 at the same time to clamp the flip platform 6 on the telescopic frame 3, and the flip drive device 5 can drive the flip platform 6 to flip.

[0037] like Figure 4 , Figure 5 As shown, the crane body 1 carries a lifting mechanism 15, and the lifting mechanism 15 lifts the telescopic frame 3 through the upper lifting belt 2. The telescopic frame 3 opens and closes through the transmission mechanism 13. After the telescopic frame 3 is closed, the turning drive device 5 fixed thereon cooperates with the turning platform 6 to realize the lifting, hoisting and turning of the turning platform 6. At this time, the mold 10 fixed on the turning platform 6 will be lifted, hoisted and turned together with the turning platform 6 through the hydraulic clamp 8 or the bolt group 9.

[0038] like Figure 6-Figure 9 As shown, the mold 10 has been fixed on the flip platform 6 by the hydraulic clamp 8 or the bolt group 9, the telescopic frame 3 is driven by the hydraulic push rod or the electric push rod 13 to close and grasp the flip platform 6, and the mold 10 is lifted a certain distance from the ground by the lifting mechanism 15. At this time, the power source 5-1 of the flip drive device 5 is started, the flip drive device 5 is actuated, and the flip platform 6 is driven to flip through the gear transmission, thereby driving the mold 10 to flip.

[0039] like Fig.10As shown, a hydraulic push rod or an electric push rod 13, a guide device 12, and a telescopic frame hook 4 are arranged on the upper part of the telescopic frame 3. If a hydraulic drive is used, a hydraulic system 7 is installed on the upper part of the telescopic frame 3 to provide power, and the transmission mechanism 13 drives the telescopic frame support arm 3-3 to drive the telescopic arm 3-2 to extend and retract in the telescopic frame cross beam 3-1, so that the telescopic frame 3 can achieve the working effect of opening and closing. In this process, the four groups of guide devices 12 fixed on the telescopic frame 3 play a role in preventing the telescopic frame 3 from deforming when the telescopic frame 3 is extended and retracted, and the flip drive device 5 is fixed. It is fixed on the telescopic frame support arm 3-3 and opens and closes with the telescopic frame 3. When the telescopic frame 3 opens, the flip drive device 5 is separated from the flip platform 6. When the telescopic frame 3 is closed, the flip drive device 5 cooperates with the flip platform 6. The 3-4 lifting lug is a connection device for the lifting mechanism 15 to lift the telescopic frame 3 through the upper lifting belt 2. The telescopic frame hook 4 is installed on the telescopic frame crossbeam 3-1. When the mold 10 does not need to be flipped, the upper lifting belt 2 or a wire rope can be used to hang a plurality of telescopic frame hooks 4 on the telescopic frame 3 to directly lift the mold. The telescopic frame hook 4 is only used when the mold 10 needs to be lifted. The number of telescopic frame hooks 4 is determined according to the size of different molds, so that a telescopic frame can lift multiple molds.

The power source 5-1 adopts an electric motor or a hydraulic motor. The power source 5-1 is fixed on the telescopic frame support arm 3-3 through the driving fixed seat 5-2, and the bearing seat 5-7 is fixed on the telescopic frame support arm 3-3 through the bearing seat fixed seat 5-8. The frame support arm 3-3 plays the role of supporting the main shaft 5-9. The pinion 5-3 is fixed on the power source 5-1 and meshes with the large gear 5-4. The large gear 5-4 and the active flange 5-6 are fixed on the main shaft 5-9 and rotate with it. The four pins 5-10 are fixed on the active flange 5-6 and cooperate with the driven flange 5-5. The hydraulic slip ring device can be used at the flip position of the active flange 5-6; the active flange 5-6 and the driven flange 5-5 can be used at the cooperation. Quick-change joints. The driven flange 5-5 can rotate with the active flange 5-6, and the driven flange 5-5 is fixed on the flip platform 6, so that the flip platform 6 can rotate with the driven flange 5-5. When the power source 5-1 is working, the pinion 5-3 rotates and drives the large gear 5-4 to rotate, the large gear 5-4 drives the active flange 5-6 to rotate, the active flange 5-6 drives the driven flange 5-5 to rotate, the driven flange 5-5 drives the flip platform 6 to rotate, and the flip platform 6 drives the mold 10 fixed thereon to rotate.

[0041] like Fig.12As shown, the flip platform 6 is composed of a platform 6-1 and a fixed shaft 6-2, and the two ends of the flip platform 6 are fixed with a driven flange 5-5 through the fixed shaft 6-2. One side of the driven flange 5-5 has a long hole to cooperate with the platform 6-1 to enhance the force. The upper and lower planes of the platform 6-1 have T-shaped holes at different positions according to different molds. The mold 10 can be fixed by a hydraulic clamp 8 or a bolt group 9. The T-shaped positions on the upper and lower sides of the platform 6-1 depend on the type of mold, so that one platform can be equipped with multiple molds. The driven flange 5-5 is fixed to the two ends of the flip platform 6 through the fixed shaft 6-5, and is clamped at the two ends of the mold 10 to enhance the force by opening a long hole on one side.

[0042] like Fig.13 As shown, when only the mold 10 needs to be lifted, the telescopic frame 3 may not grab the reversal platform 6, and the mold 10 can be hung on the telescopic frame hook 4 on the telescopic frame 3 using the lower lifting belt 14. The lower lifting belt 14 can also be made of a wire rope. The mold 10 is lifted together with the telescopic frame 3 through the lifting mechanism 15 and moves along with the trolley running mechanism 16, thereby achieving the purpose of lifting.

The running sports car 3-8 drives the telescopic frame support arm 3-3 to move on the telescopic frame cross beam 3-1 to achieve the telescopic frame 3. The lower cover plate of the telescopic frame cross beam 3-1 is thickened and can be used as a sports car track. The running sports car 3-8 is fixed to the telescopic frame support arm 3-3 by an articulated manner to prevent the sports car wheels from contacting the sports car track at different times. The anti-rollover sports car 3-7 is fixed to the telescopic frame support arm 3-3 by an articulated manner to prevent the telescopic frame support arm 3-3 from tipping over when a force is applied.
