Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] Figure 1-3 The components include a fixed frame connecting plate 1, a hydraulic cylinder connecting seat 2, a tilting frame connecting plate 3, a locking pin 4, an induction switch 5, a locking hydraulic cylinder 6, a tilting hydraulic cylinder 7, a tilting frame 8, a fixed frame 9, and a rubber pad 10.

[0021] like Figure 1-3 As shown, this utility model is a hydraulic locking device, characterized in that it includes a flipping frame 8, one end of which is hinged to the base and driven by a flipping cylinder 7 to perform a flipping motion, and the flipping cylinder 7 is rotatably mounted on a fixed frame 9.

[0022] A flipping frame connecting plate 3 is installed on the flipping frame 8, and the flipping frame connecting plate 3 moves synchronously with the flipping frame 8.

[0023] Two parallel connecting plates 1 are fixedly mounted on the fixed frame 9. When the tilting cylinder 7 drives the tilting frame 8 to rotate to a horizontal position, the tilting frame 8 is supported on the fixed frame 9. At this time, the tilting frame connecting plate 3 extends between the two connecting plates 1. A rubber pad 10 is provided on the top surface of the fixed frame 9 so that when the tilting frame 8 is driven by the tilting cylinder 7 to rotate to a horizontal state, the rubber pad 10 can play a reliable shock absorption and buffering role for the tilting frame 8.

[0024] A locking cylinder 6 is installed on the outer surface of the fixed frame connecting plate 1. A locking pin 4 is installed on the piston rod end of the locking cylinder 6. The locking pin 4 can lock and position the tilting frame connecting plate 3 and the fixed frame connecting plate 1.

[0025] An induction switch 5 is installed on the outside of the locking cylinder 6 to sense the position of the locking pin 4.

[0026] The fixed frame connecting plate 1 is provided with a first locking hole, and the flipping frame connecting plate 3 is provided with a second locking hole. When the flipping frame 8 is supported on the fixed frame 9, the first locking hole and the second locking hole are coaxially aligned and aligned. The locking pin 4 can extend into the first locking hole and the second locking hole under the drive of the locking cylinder 6.

[0027] The outer side of the fixed frame connecting plate 1 is fastened to the cylinder connecting seat 2, the locking cylinder 6 is installed on the cylinder connecting seat 2, and the induction switch 5 is installed on the cylinder connecting seat 2.

[0028] The inductive switch 5 is installed on the cylinder connecting seat 2 near the tail end. When the piston rod of the locking cylinder 6 retracts, the inductive switch 5 can sense the locking pin 4.

[0029] When the tilting frame is tilted to the end position, the tilting frame connecting plate 3 and the fixed frame connecting plate 1 are locked together. When the locking cylinder 6 is working, the locking pin 4 moves linearly to lock the tilting frame connecting plate 3 and the fixed frame connecting plate 1, thereby completing the locking of the tilting frame. After the induction switch 5 senses that the locking pin 4 is in the locked state, the induction switch 5 controls the tilting frame to prevent it from working again, thus avoiding damage to the equipment due to the failure to release the mechanical lock.

[0030] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
