[0032] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0033] like Figure 1 , Figure 2 As shown, an eccentric tipping positioner is installed in a foundation dug under the ground; the active end head frame assembly 1 of the tipping machine is fixed, the driven end tail frame assembly 5 is connected to the walking mechanism 6, and a tipping device 3 is installed on the active end head frame assembly 1 and the driven end tail frame assembly 5 to adapt to the sizes of three types of water well drilling rig frames 4.

[0034] The walking mechanism 6 is composed of a walking motor 22, a walking rack 21, a walking guide rail 20, a walking cover plate 19, etc. The walking motor 22 is a reduction motor, which is fixed to the movable box of the driven end tail frame assembly 5 by bolts. The output end of the walking motor 22 is equipped with a gear meshing with the walking rack 21. The walking guide rail 20 is arranged along the Figure 1 The travel cover 19 is composed of a guide rod and multiple layers of overlapped stainless steel plates. The guide rod is used as a guide. The stainless steel plates are overlapped and stacked up and down. The tail is fixed to the ground, and the head is connected to the driven end tail frame assembly 5. During the movement of the travel mechanism 6, the travel cover 19 will be pulled out or retracted to ensure that no potholes appear and reduce the safety hazards of the equipment.

[0035] Combination Figure 3 As shown, one side of the slewing bearing 15 included in the turning device 3 is connected to the slewing plate 13 by bolts, and the other side is connected to the fixed box 18. The other side of the slewing plate 13 fixes the entire turning frame 11 by bolts, and the slewing bearing 15 can realize 180° turning of the turning frame 11. The turning device 3 is driven by a turning motor 17 placed away from the center of gravity of the workpiece. The turning motor 17 drives the turning gear 16, and the turning gear 16 is meshed with the slewing bearing 15 for transmission, thereby driving the slewing bearing 15 and the turning frame 11 to realize the eccentric rotation of the workpiece. Since the turning frame 11 is equipped with a hydraulic oil pipe, the hydraulic oil pipe cannot be twisted, so a rotary joint 14 is installed on the turning machine to realize that the oil pipe is not affected by the force generated by the turning during turning.

[0036] Combination Figure 1 , Figure 2 As shown, when installing the water well drilling rig frame 4, select and determine the model of the water well drilling rig frame 4 that needs to be flipped in advance in the control cabinet, the travel motor 22 in the travel mechanism 6 drives the driven end tail frame assembly 5 to the corresponding position through the travel guide rail 20 and the travel gear, and the crane lifts the water well drilling rig frame 4 and adjusts the frame position so that the two ends of the water well drilling rig frame 4 are placed on the workpiece support plates 9 at both ends, and the water well drilling rig frame 4 is turned over. Figure 3-Figure 7 As shown, the position of the water well drilling rig frame 4 is fine-tuned to ensure good contact with the blocking block 10, and the tensioning cylinder 26 is controlled to retract through the electric control cabinet 8 or a wireless remote controller. The tensioning cylinder 26 drives the side clamping block to press the water well drilling rig frame 4 laterally through the linear rail slider 12, and then the control cabinet or a wireless remote controller is used to control the clamping cylinder 24 to retract, thereby driving the clamping plate 25 to longitudinally press the water well drilling rig frame 4, thereby completing the installation and clamping of the workpiece.

[0037] When the water well drilling rig frame 4 needs to be flipped, the flip motor 17 in the fixed box 18 is controlled by the electric control cabinet 8, and the flip motor 17 drives the slewing bearing 15 to rotate through the flip gear 16, so that the slewing bearing 15 at the active end rotates and transmits the torsional force through the frame, thereby driving the slewing bearing 15 at the driven end to rotate synchronously, so that the frame performs an eccentric flip of 180°. During the flipping process, there is an audible and visual alarm to remind the surrounding staff to stay away. During the flipping process, the pit door opening mechanism 7 responds to the flipping action to open and close, and the door opening mechanism 7 in the pit door opening mechanism 7 The oil cylinder 27 is connected to the door cover plate 28. The door cylinder 27 contracts to open the door cover plate 28. When the system confirms that the pit door opening mechanism 7 is normally opened, the flipping device 3 performs the flipping action normally, otherwise it does not act; when the flipping action of the flipping device 3 is completed, the pit door opening mechanism 7 automatically closes, and the operator can stand on the door cover plate 28 to assemble the workpiece, wherein the auxiliary support 2 is not subjected to force during the flipping process. The auxiliary support 2 can adjust the height through the T-shaped thread, which does not affect the level of the flipping machine. It is a safety protection support designed to prevent the side tilt during the eccentric flipping process. Because the frame is flipped 180° eccentrically, there is no need to lift and lower during the flipping process. The assembly height after the flipping is completed is guaranteed to be about one meter. The comfortable assembly height further improves efficiency and reduces safety risks.

[0038] After being flipped into place, the machine stops running immediately and all the oil cylinders are in a locked state, which together with the auxiliary support 2 ensures that the workpiece will not rotate accidentally during the assembly process, thereby improving safety and reliability.

[0039] From the above description, it can be seen that the present invention utilizes a small pit to avoid the protruding part of the water well drilling rig frame 4, thereby preventing the complex structure of the frame from interfering with the ground during flipping; the flipping motor 17 is eccentrically placed with the center of gravity of the frame to perform eccentric flipping, so that the appropriate assembly height is achieved after the flipping is completed, eliminating the cumbersome structure and actions of lifting and lowering; and it is suitable for various types of water well drilling rigs, is lighter and more convenient to use, occupies less space, has higher production efficiency, further improves safety, saves labor time, and improves work efficiency.

[0040] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
