Referring to fig. 2, the guide structure includes a box body 2 with an open lower end, and the box body 2 is formed by connecting an upper plate 3, two side plates 4, a front plate 5 and a rear plate 6 through a plurality of connecting screws 7. The front parts of the two side plates 4 are higher than the rear parts thereof, the side plates 4 of the embodiment adopt L-shaped plate structures which are turned clockwise for 90 degrees, but the included angle of the openings of the plate bodies is an obtuse angle which is larger than 90 degrees. The front height of the side plates 4 is greater than the height of the front and rear plates 5, 6. The upper plate 3 is provided with a rectangular opening 8 above the power mechanism, but may be an opening of other shapes. The purpose of this opening 8 is to partially accommodate the opening 8 when the power mechanism is in the locked condition, and the provision of this opening 8 allows for a more compact locking mechanism of the present invention.
As shown in fig. 1 and 5, the front portions of the two side plates 4 are symmetrically provided with two elongated holes 9, or may be two elongated holes. The shape of the long hole 9 in this embodiment is similar to that of the side plate 4, and an inverted 90-degree L-shaped long hole is adopted, and the opening included angle of the long hole 9 is an obtuse angle greater than 90 degrees, and the opening included angle of the long hole 9 in this embodiment is equal to the opening included angle of the side plate 4. The cross section width of the long hole 9 is equal, two semicircular ends of the long hole 9 are equal to the semicircular diameters of the two ends, and the included angle of the opening of the long hole 9 is in smooth arc transition.
The latch hook 1 is a plate body with a U-shaped cross section, the upper end of the rear part of the latch hook 1 is arranged on the connecting shaft 10, the two ends of the connecting shaft 10 are arranged on the two long holes 9, the front end of the latch hook 1 extends out of the bottom opening of the box body 2 to the front of the box body 2, and the movement track of the latch hook 1 is determined by the shape of the long holes 9.
As shown in fig. 6, the power mechanism of the present embodiment employs a hydraulic drive system. As shown in fig. 1, 3 and 4, the power mechanism includes a hydraulic cylinder 11 and a three-position four-way electromagnetic directional valve 12. A part of the hydraulic ram 11 may be accommodated in the opening 8. The outer side end of the cylinder body 13 of the hydraulic cylinder 11 is provided with a hinged plate 14, a hinged seat 15 is arranged on the inner wall of the rear plate 6 of the box body 2, and the hinged plate 14 and the hinged seat 15 are connected together through a pin 16. The outer end of the piston rod 17 of the hydraulic cylinder 11 is vertically connected with the rear side surface of the latch hook 1. The rear end of the piston rod 17, i.e. the piston end, divides the inner cavity of the cylinder 13 into a first chamber 18 (positive chamber) and a second chamber 19 (negative chamber), the rod portion of the piston rod 17 being located in the second chamber 19. The first chamber 18 is communicated with an A port of the three-position four-way electromagnetic directional valve 12 through a first oil pipe 20, and the second chamber 19 is communicated with a B port of the three-position four-way electromagnetic directional valve 12 through a second oil pipe 21. The first oil pipe 20 is provided with a first hydraulic control one-way valve 22, a first pressure sensor 23 and a first pressure measuring joint 24, and the second oil pipe 21 is provided with two second hydraulic control one-way valves 25, a second pressure sensor 26 and a second pressure measuring joint 27. The first hydraulic check valve 22 is used for locking the first chamber 18 (positive chamber) of the hydraulic cylinder 11, the second hydraulic check valve 25 is used for locking the second chamber 19 (negative chamber) of the hydraulic cylinder 11, and two second hydraulic check valves 25 are arranged at the negative chamber to form a double hydraulic lock for realizing redundant locking of the locking mechanism. The second oil pipe 21 is communicated with an energy accumulator 28, the energy accumulator 28 is used for realizing pressure maintaining in the equipment action process, and the pressure continuously acts on the reverse cavity of the hydraulic oil cylinder 11, so that the lock hook 1 is always in a tightening state, and the abutting equipment is prevented from being disconnected.
The first pressure sensor 23, the second pressure sensor 26, the first pressure measuring connector 24, the second pressure measuring connector 27, the first hydraulic control check valve 22 and the second hydraulic control check valve 25 can be integrated in a hydraulic control valve group, so that the position control and the locking and retaining of the locking hook type hydraulic locking mechanism are realized. The redundant locking function is achieved by providing the second chamber 19 of the hydraulic ram 11 in the hydraulic circuit as a double hydraulic lock, i.e. by mounting two second pilot operated check valves 25 on the second oil line 21 communicating with the second chamber 19. If a plurality of groups of hydraulic locking mechanisms are adopted to act simultaneously, the hydraulic cylinders of the newly added mechanisms can be directly connected in parallel on the basis of the original hydraulic cylinders 11, so that the balanced output of locking force can be realized, and a plurality of valve groups are not required to be arranged.
Referring to fig. 3 and 4, the state of the locking hook 1 of the locking mechanism of the present invention is determined by the retraction and extension of the piston rod 17 of the hydraulic cylinder 11. The action of the latch hook 1 is realized by the shape of the long hole 9, and the design structure is simple and ingenious. As shown in fig. 5, the connecting shaft 10 on the latch hook 1 does not reach the right limit and the left limit of the long hole 9, so that the excessive load of the guide structure at the left limit and the right limit can be avoided; the size range of the lock hook 1 is smaller than the length of the upper hole of the long hole 9 when the lock is locked in place, so that the locking mechanism is ensured to adapt to structures to be locked with different thicknesses; the movement track of the mechanism can be changed by adjusting the opening angle of the long hole 9, so that interference with the structure to be locked is avoided; the cross-sectional diameter of the connecting shaft 10 is slightly smaller than the cross-sectional width of the long hole 9; the roughness of the inner surface of the long hole 9 is required to be 1.6 mu m, so that the stable movement process of the mechanism is ensured.
When the three-position four-way electromagnetic reversing valve 12 is electrified, when the valve core is reversed to the left position in use, referring to fig. 6, a piston rod 17 of the hydraulic cylinder 11 stretches out rightwards, referring to fig. 4, at the moment, a connecting shaft 10 connected with the outer side end of the piston rod 17 moves to the stroke end of the hydraulic cylinder 11 according to a path planned by a long hole 9 on the side plate 4, when the pressure value of the first pressure sensor 23 reaches the oil source overflow pressure, the three-position four-way electromagnetic reversing valve 12 is powered off, and the locking mechanism reaches an extended state.
With continued reference to fig. 6, when the valve core is commutated to the right position after the three-position four-way electromagnetic directional valve 12 is electrified, the piston rod 17 of the hydraulic cylinder 11 is contracted leftwards, and with reference to fig. 3, at this time, the connecting shaft 10 connected to the outer side end of the piston rod 17 moves to the piston rod 17 to be in a contracted state according to the path planned by the long hole 9, and when the pressure value of the second pressure sensor 26 reaches the oil source overflow pressure, the three-position four-way electromagnetic directional valve 12 is powered off, and the locking mechanism reaches the locked state. Thereafter the pressure in the accumulator 28 maintains the oil source overflow pressure and this pressure continues to act on the counter chamber of the hydraulic cylinder 11 so that the shackle 1 is always in a tightened state preventing the docking device from being undone.
When the docking station is completed, the station needs to be disconnected. When the valve core is reversed to the left position after the three-position four-way electromagnetic reversing valve 12 is electrified, the piston rod 17 of the hydraulic oil cylinder 11 stretches out rightwards, and when the connecting shaft 10 connected with the outer side end of the piston rod 17 moves to the stroke end of the hydraulic oil cylinder 11 according to the path planned by the long hole 9, the three-position four-way electromagnetic reversing valve 12 is powered off when the pressure value of the first pressure sensor 23 reaches the oil source overflow pressure, the locking mechanism reaches an extended state, and the docking equipment can be disconnected.
When the device is disengaged, the locking mechanism is restored to the received position. With continued reference to fig. 6, when the valve core is reversed to the right position after the three-position four-way electromagnetic reversing valve 12 is electrified, the piston rod 17 of the hydraulic cylinder 11 is contracted leftwards, with continued reference to fig. 3, at this time, the connecting shaft 10 connected with the outer side end of the piston rod 17 moves to the piston rod 17 to be in a contracted state according to the path planned by the long hole 9, and when the pressure value of the second pressure sensor 26 reaches the oil source overflow pressure, the three-position four-way electromagnetic reversing valve 12 is powered off. To release the pressure in the accumulator 28, the three-position four-way solenoid directional valve 12 may be powered on and the valve spool switched off immediately after 1s to the left position.
The above examples are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the scope of protection defined by the claims of the present invention without departing from the spirit of the design of the present invention.
