In the technical solution, the second nut is mainly used to avoid the rotation of the lead screw under stress.

[0030] Further, the second through hole is an elliptical hole, which facilitates the quick alignment of the mounting piece and the lead screw and improves the installation efficiency.

[0031] Further, the transition bearing beam is an I-beam.

[0032] Further, the transition bearing beam is provided with an anti-wear layer in contact with the outer ring of the bearing at the bottom, thereby improving the service life of the transition bearing beam.

[0034] When the hydraulic cylinder needs to be removed, push the sliding part. With the cooperation of the sliding connecting part, the guide part, the mounting part, and the adjusting part move horizontally along the transition load-bearing beam to the top of the hydraulic cylinder. Then adjust the adjusting part so that the mounting part descends along the guide part to the hydraulic cylinder. After the mounting part is connected to the hydraulic cylinder, adjust the adjusting part again to drive the mounting part and the hydraulic cylinder to rise along the guide part. When the hydraulic cylinder leaves the main body of the blow molding equipment, push the sliding part. The hydraulic cylinder will move outward with the sliding part. After moving outward into place, adjust the adjusting part again and the hydraulic cylinder will move downward.

With the cooperation of the sliding connection part, the guide part, the mounting part, and the adjusting part move horizontally along the transition load-bearing beam to the top of the hydraulic cylinder. Then adjust the adjusting part so that the mounting part descends along the guide part to the hydraulic cylinder. After the mounting part is connected to the hydraulic cylinder, adjust the adjusting part again to drive the mounting part and the hydraulic cylinder to rise along the guide part. When it rises to the set position, push the sliding part. The hydraulic cylinder will move toward the blow molding equipment along with the sliding part. When it moves to the top of the installation position, adjust the adjusting part again. The hydraulic cylinder will move downward.

[0049] The sliding connection 2 includes a connection plate and a bearing.

[0050] The transition load-bearing beam 1 is an I-beam.

[0051] Specifically, in this embodiment, the sliding member 3 is connected to the connecting plate, and the connecting plate is then slidably connected to the transition load-bearing beam 1 through a bearing (the connecting plate is connected to the inner ring of the bearing).

[0052] The connection portion of the anti-falling member 7 is connected to the sliding member 3, and the pre-hanging portion is arranged above the bottom of the transition load-bearing beam 1, with a gap between the pre-hanging portion and the bottom of the transition load-bearing beam 1. One side of the bottom of the transition load-bearing beam 1 and one side of the sliding member 3 are both placed on the inner side of the anti-falling member 7.

[0053] The top end of the screw rod 4 is threadedly engaged with the threaded hole corresponding to the sliding member 3, and is detachably connected to the sliding member 3 with the cooperation of the second nut 10. The second nut 10 is mainly used to prevent the screw rod 4 from rotating after being subjected to force.

[0059] When the hydraulic cylinder A needs to be installed, the sliding member 3 is pushed, and under the cooperation of the sliding connecting member 2, the screw rod 4, the mounting member 5 and the first nut 6 are moved transversely above the hydraulic cylinder A along the transition load-bearing beam 1, and then the four first nuts 6 are synchronously rotated in the downward direction, so that the mounting member 5 is lowered onto the hydraulic cylinder A along the screw rod 4; after the mounting member 5 is connected with the hydraulic cylinder A, the four first nuts 6 are synchronously rotated in the upward direction, driving the mounting member 5 and the hydraulic cylinder A to move upward along the screw rod 4; when the hydraulic cylinder A is separated from the blow molding equipment main body, the sliding member 3 is pushed, and the hydraulic cylinder A moves outward with the sliding member 3; after moving outward to the position, the four first nuts 6 are synchronously rotated in the downward direction, and the hydraulic cylinder A moves downward; when the hydraulic cylinder A is lowered to the bottom, the mounting member 5 and the hydraulic cylinder A are separated by the tray, and the hydraulic cylinder A is successfully removed.

[0060] The embodiment can easily realize the lifting action and transverse movement of the heavy hydraulic cylinder A, can replace the complete manual carrying in a small space, improve the efficiency of disassembling and assembling the hydraulic cylinder A, and greatly improve the safety during the disassembling and assembling process.

[0061] In addition, in the embodiment, if the sliding connecting piece 2 cannot bear the total weight of the lifting installation assembly and the hydraulic oil cylinder A and the lifting installation assembly and the hydraulic oil cylinder A fall down, the pre-hanging part of the anti-falling piece 7 is hung on the bottom of the transition load-bearing beam 1, so that the situation that the lifting installation assembly and the hydraulic oil cylinder A completely fall down is avoided.

[0062] The gap between the pre-hanging part and the bottom of the transition load-bearing beam 1 avoids affecting the sliding of the sliding piece 3 along the transition load-bearing beam 1.

[0063] The anti-falling piece 7 is in a "concave" shape, and the pre-hanging part and the connecting part can be integrally formed during production, so that the firmness is high.

[0064] The second through hole 9 is an elliptical hole, which facilitates the quick alignment of the mounting piece 5 and the lead screw 4 and improves the installation efficiency.

[0065] The bottom of the transition load-bearing beam 1 is provided with an anti-wear layer 11 in contact with the outer ring of the bearing, so as to improve the service life of the transition load-bearing beam 1.

[0066] The above-mentioned embodiments are only preferred embodiments of the utility model, and do not limit the implementation range of the utility model, so that any change made according to the shape and principle of the utility model should be covered in the protection range of the utility model.
