[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0027] It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings. At the same time, in the description of the present invention, directional terms and order terms are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figures 1 to 3 As shown, the jacking rotation failure protection device has a carrier 2 installed on a mounting seat 1, a power unit 7 and a jacking cylinder 4 installed on the carrier 2, a lower shaft 5 which can move up and down is vertically inserted on the power shaft of the power unit 7, the lower part of the lower shaft 5 is matched in an oil-free bushing 6, the oil-free bushing 6 is installed on the carrier 2, the upper part of the lower shaft 5 is supported on a bearing seat 8, a jacking plate 19 is installed on the vertical piston rod of the jacking cylinder 4, and the jacking plate 19 is connected to the bearing seat 8, and can drive the bearing seat 8 and the lower shaft 5 to move up and down;

[0029] The top end of the lower shaft 5 is connected to the lower V-mouth piece 10, and the two are connected by a flange structure. The lower V-mouth piece 10 has a lower V-mouth portion and a thin-diameter shaft portion 18 for matching with the upper V-mouth piece 11. Correspondingly, the upper V-mouth piece 11 has an upper V-mouth portion and an axial hole. The upper V-mouth piece 11 is matched with the lower V-mouth piece 10, the thin-diameter shaft portion 18 is matched with the axial hole, and the upper V-mouth portion matches the lower V-mouth portion.

[0030] The lower shaft 5 is connected to the power unit 7 via a guide flat key, and the lower shaft 5 can transmit the rotational motion of the power unit 7 while rising and falling with the lifting cylinder 4;

[0031] A cross carrier 14 is fixed at the top of the upper V-mouth 11, and a support bar 13 that can rotate upward is hingedly connected to the support arm of the cross carrier 14 through a pin shaft. When the upper V-mouth 11 moves upward, the support bar 13 can be in an open state, and when it moves downward, the support bar 13 can be in a closed state. Suction cups 12 for adsorbing products are distributed on the upper plane of the support bar 13.

[0032] An induction ring 15 is sleeved on the upper V-mouth piece 11 , and a lower sensor 16 and an upper sensor 17 for detecting the up and down movement position of the induction ring 15 are arranged on its side.

[0033] A slide rail is provided on the mounting seat 1 in the up and down directions, and the mounting platform 2 is placed on the slide rail through a slide groove. A screw seat 3 is installed on the mounting seat 1, and the adjusting screw on the screw seat 3 cooperates with the nut sleeve on the mounting platform 2. Rotating the adjusting screw can drive the mounting platform 2 to move up and down along the slide rail.

[0034] In specific applications, the lifting cylinder 4 is lifted, the lifting plate 19 drives the bearing seat 8 and the lower shaft 5 to move upward, and the support bar 13 lifts the product;

[0035] When the power unit 7 works, the power shaft rotates to drive the lower shaft 5 to rotate, the upper V-mouth portion of the upper V-mouth piece 11 engages with the lower V-mouth portion of the lower V-mouth piece 10, so that the upper V-mouth piece 11 and the support bar 13 rotate, and the support bar 13 drives the product to rotate, and the rotation angle of the lower shaft 5 can be controlled;

[0036] The lifting cylinder 4 retracts, and the lifting plate 19 drives the bearing seat 8 and the lower shaft 5 to move downward, and the product is separated from the support bar, completing the change of product direction.

[0037] If the lifting cylinder fails to lift, the power unit 7 works, the rotation of the support bar 13 is blocked by the equipment, the upper V-mouth portion of the upper V-mouth member 11 and the lower V-mouth portion of the lower V-mouth member 10 rotate relative to each other, from the bite state to the phase separation, and the upper V-mouth member 11 rises along the axial direction, as shown in FIG. Figures 4 to 8 As shown, the power generated by the rotation action is released. The sensor detects the position information of the induction ring 15 and promptly alarms, and the maintenance personnel stops the equipment and eliminates the failure of the jacking cylinder.

[0038] The upper V-mouth piece is rigidly connected to the actuator, and the lower V-mouth piece is rigidly connected to the power source. They are connected by a V-shaped structure. This structure can transmit a certain amount of rotational motion, but when there is a large resistance on one side of the actuator, the V-shaped connection structure will disengage up and down, playing a safety protection role.

[0039] In summary, the present invention has a unique design and novel structure, and can release the impact generated by the mechanism action when the mechanism fails, thereby preventing damage to equipment and products when the action fails, and avoiding unnecessary waste of time and economic losses.
