[0034] In order to solve the technical problems of complex structure and inconvenient maintenance of the driving device in the prior art, the embodiment of the present application provides a driving device for a ship lift gate pier working door. The driving device solves the technical problems of complex structure and inconvenient maintenance of the existing driving device, and achieves the technical effects of simple structure, convenient maintenance and ensuring the reliability of long-term operation of the gate.

[0035] Please refer to Figure 1 and Figure 2 , Figure 1 the front view of the driving device for the gate pier working door provided by the embodiment of the present application, Figure 2 the side view of the driving device for the gate pier working door provided by the embodiment of the present application. The driving device comprises a gate leaf 1, a gate structure 2, a bearing assembly 3, a bearing seal group 4, a spline shaft 6, a crank 8, a hydraulic oil cylinder 9 and a controller;

[0036] The bearing assembly 3 is symmetrically arranged on both sides of the gate structure 2, the bearing seal group 4 is arranged on the wall plate 5 on both sides of the gate structure 2, one end of the spline shaft 6 is connected with the bearing assembly 3, and the other end extends to the outside of the wall plate 5 through the bearing seal group 4;

[0037] The bottom of the gate leaf 1 is symmetrically fixed with a lug plate assembly 7, and the lug plate assembly 7 is connected with the spline shaft 6;

[0038] The first end of the crank arm 8 is connected with the end of the spline shaft 6 outside the wall plate 5, one end of the hydraulic cylinder 9 is hinged to the hydraulic cylinder support, and the other end is hinged to the second end of the crank arm 8, and the hydraulic cylinder 9 is signal connected with the controller.

[0039] Specifically, the lock structure 2 is the main support structure of the lock working door, which is firmly embedded in the navigation channel to provide mechanical support. The lock structure 2 is a thin-walled concave steel box structure to ensure stability. The concave groove of the lock structure 2 serves as the space for the movement of the door leaf 1 and needs to have sufficient strength and stability to withstand the impact of water flow and the pressure generated during the opening and closing of the gate. The support assembly 3 is symmetrically arranged on both sides of the lock structure 2 to provide reliable support for the door leaf 1. At the same time, in order to further enhance the sealing performance, the wall plate 5 is provided with a support sealing group 4 cooperating with the spline shaft 6, and a seal is formed between the support sealing group 4 and the wall plate 5 to prevent water leakage and ensure the sealing performance during the opening and closing of the gate.

[0040] One end of the spline shaft 6 is connected with the support assembly 3, and the other end extends to the outside of the wall plate 5 through the support sealing group 4. The bottom of the door leaf 1 is symmetrically provided with an ear plate assembly 7, and the ear plate assembly 7 is connected with the spline shaft 6 through a fixed connection to realize power transmission.

[0041] The first end (bottom) of the crank arm 8 is fixedly connected with the end of the spline shaft 6 outside the wall plate 5, and the second end (top) is hinged to the piston rod of the hydraulic cylinder 9. The other end (fixed end) of the hydraulic cylinder 9 is hinged to the hydraulic cylinder support, and the controller is signal connected with the hydraulic cylinder 9 to adjust the extension and retraction speed and stroke of the hydraulic cylinder 9 as needed. By controlling the extension and retraction of the hydraulic cylinder 9, the crank arm 8 can be driven to rotate, and the spline shaft 6 can be rotated, and the ear plate assembly 7 can convert the rotary motion of the spline shaft 6 into the opening and closing action of the door leaf 1 to realize the opening and closing of the gate.

[0042] In summary, when the lock working door needs to be opened or closed, the controller receives the control signal from the outside, adjusts the extension and retraction speed and stroke of the hydraulic cylinder 9, controls the extension and retraction of the piston rod of the hydraulic cylinder 9, drives the crank arm 8 to rotate, drives the spline shaft 6 to rotate, and the ear plate assembly 7 converts the rotary motion of the spline shaft 6 into the opening and closing action of the door leaf 1 to realize the opening and closing of the gate. In summary, the driving device of the lock working door provided by the present application comprises a support assembly, a support sealing group, a spline shaft, an ear plate assembly, a crank arm and a hydraulic cylinder, which can realize the opening and closing action of the door leaf, and the structure is simple, easy to maintain and ensures the reliability of long-term operation of the gate, providing reliable protection for the operation of water conservancy projects.

[0043] Specifically, the spline shaft 6 is provided in two groups, and the ear plate assembly 7, the toggle arm 8 and the hydraulic cylinder 9 are also provided in two groups, which jointly act on the same gate leaf 1 to provide sufficient power to realize the rotating action of the gate leaf 1.

[0044] Specifically, the ear plate assembly 7 includes an ear plate 71 and a sleeve 72, one end of the ear plate 71 is fixedly arranged at the bottom of the gate leaf 1, and the other end is connected to the outer circumferential surface of the sleeve 72, and the sleeve 72 is sleeved on the spline shaft 6. The spline shaft 6 is provided with a first outer spline 61 and a second outer spline 62, and the first outer spline 61 and the second outer spline 62 are uniformly distributed in the circumferential direction of the spline shaft 6, the first outer spline 61 is located on the inner side of the wall plate 5, and the second outer spline 62 is located on the outer side of the wall plate 5. The hole wall of the sleeve 72 is provided with a first inner spline, and the first inner spline is connected with the first outer spline 61.

[0045] That is, one end of the ear plate 71 is firmly mounted at the bottom of the gate leaf 1, thereby ensuring that the ear plate 71 can stably transmit power when the gate leaf 1 rotates, and the other end of the ear plate 71 is connected to the outer circumferential surface of the sleeve 72, allowing the ear plate 71 to transmit the rotating force from the spline shaft 6 to the sleeve 72.

[0046] The first outer spline 61 and the second outer spline 62 on the spline shaft 6 are uniformly distributed in the circumferential direction of the spline shaft 6, which helps to ensure that the spline shaft 6 can be uniformly stressed when rotating, thereby improving the transmission efficiency. The sleeve 72 is sleeved on the spline shaft 6, so that the sleeve 72 can rotate with the spline shaft 6, thereby driving the gate leaf 1 to rotate. In order to ensure the stable connection between the sleeve 72 and the spline shaft 6, the hole wall of the sleeve 72 is provided with a first inner spline matched with the first outer spline 61. The first inner spline of the sleeve 72 is matched with the first outer spline 61 on the spline shaft 6, which ensures that the sleeve 72 can rotate with the spline shaft 6 and will not slide or deviate during rotation. Therefore, when the hydraulic cylinder 9 drives the spline shaft 6 to rotate through the toggle arm 8, the ear plate assembly 7 can stably convert this rotating motion into the rotating action of the gate leaf 1, thereby realizing the opening and closing of the gate.

[0047] Specifically, the ear plate assembly 7 needs to maintain a proper distance from the wall plate 5 during installation to avoid friction with the wall plate 5 during transmission.

[0048] Based on the above embodiment, referring to Figure 1 , the first end of the toggle arm 8 is provided with a second inner spline matched with the second outer spline 62, and the outer side of the toggle arm 8 is detachably connected with a first cover plate 81, and the first cover plate 81 limits the axial movement of the spline shaft 6.

[0049] That is, the first end (bottom) of the toggle arm 8 is provided with a second inner spline, which cooperates with the second outer spline 62 on the spline shaft 6. Through the cooperation of the inner and outer splines, it is ensured that the toggle arm 8 can be closely connected with the spline shaft 6 during power transmission, avoiding possible sliding or deviation during transmission.

[0050] In addition, in order to further enhance the stability of the connection between the toggle arm 8 and the spline shaft 6, the outer side of the toggle arm 8 is detachably connected with a first cover plate 81. The function of the first cover plate 81 is to limit the axial movement of the spline shaft 6. During transmission, the spline shaft 6 may produce axial displacement, which may cause instability or even damage to the transmission system. Through the limiting action of the first cover plate 81, the axial movement of the spline shaft 6 can be effectively prevented, thereby ensuring the stability and reliability of the entire transmission process.

[0051] At the same time, the detachable design of the first cover plate 81 makes it easy to detach the first cover plate 81 when maintenance or replacement of parts is needed, thereby facilitating the inspection and repair of the spline shaft 6 and the toggle arm 8. Specifically, the first cover plate 81 is closely connected with the toggle arm 8 through bolts.

[0052] Based on the above embodiment, referring to Figure 1 , the support assembly 3 includes a first support seat 31 and a second support seat 32, both of which are provided with a support sleeve 33 that closely fits the outer peripheral surface of the spline shaft 6. The sleeve 72 is connected to the spline shaft 6 between the first support seat 31 and the second support seat 32; the outer side of the second support seat 32 is detachably connected with a second cover plate 34, which limits the axial movement of the spline shaft 6.

[0053] That is, the first support seat 31 and the second support seat 32 are both provided with a support sleeve 33 that closely fits the outer peripheral surface of the spline shaft 6, ensuring that the spline shaft 6 can be uniformly supported during rotation, reducing wear and vibration caused by uneven stress. At the same time, the support sleeve 33 is made of wear-resistant material and can withstand high loads and frequent movements during transmission, thereby prolonging the service life of the support assembly. The sleeve 72 is connected to the spline shaft 6 between the first support seat 31 and the second support seat 32, allowing the lug plate assembly 7 to stably transmit the rotational force of the spline shaft 6, thereby driving the leaf 1 to rotate.

[0054] In order to further enhance the stability and safety of the support assembly 3, the outer side of the second support seat 32 is provided with a detachable second cover plate 34, which is closely connected with the second support seat 32 through bolts to limit the axial movement of the spline shaft 6, preventing possible axial displacement of the spline shaft 6 during transmission, thereby ensuring the stability and reliability of the transmission system.

[0055] Referring to Figure 3The support sealing group 4 comprises a bushing 41 detachably connected to the wall plate 5, a first mounting hole, a second mounting hole and a third mounting hole are arranged in the middle of the bushing 41 and communicate with each other; a shaft sleeve 42 is arranged in the first mounting hole and the shaft sleeve 42 is sleeved on the spline shaft 6; a packing 43 is arranged in the third mounting hole and the packing 43 is sleeved on the spline shaft 6; an inner end cover 44 is detachably connected to the inner side end surface of the bushing 41 so that the shaft sleeve 42 is fixedly arranged in the first mounting hole; and an outer end cover 45 is detachably connected to the outer side end surface of the bushing 41 so that the packing 43 is fixedly arranged in the third mounting hole.

[0056] That is, the support sealing group 4 comprises the bushing 41 which is detachably connected to the wall plate 5, and specifically, the bushing 41 is connected to the wall plate 5 through bolts, which is convenient for maintenance and replacement. The middle of the bushing 41 is provided with three holes which communicate with each other, that is, the first mounting hole, the second mounting hole and the third mounting hole.

[0057] The shaft sleeve 42 is arranged in the first mounting hole, and the shaft sleeve 42 is designed to be closely sleeved on the spline shaft 6 to provide stable positioning. The material of the shaft sleeve 42 is usually selected from wear-resistant and corrosion-resistant materials to ensure its stability and reliability in long-term operation. Since the first support seat 31 and the second support seat 32 provide support force for the spline shaft 6, the shaft sleeve 42 only needs to overcome the slight jumping of the spline shaft 6 outside the first support seat 31 and the second support seat 32 when the toggle arm 8 rotates due to deformation.

[0058] In the third mounting hole, the packing 43 is arranged and can be closely sleeved on the spline shaft 6 to prevent liquid leakage from the gap between the spline shaft 6 and the bushing 41. The inner end cover 44 is detachably connected to the inner side (right side) end surface of the bushing 41, which serves to fix the shaft sleeve 42 and ensure that the shaft sleeve 42 is stably retained in the first mounting hole and will not be displaced or fall off during operation. The outer end cover 45 is detachably connected to the outer side (left side) end surface of the bushing 41, which serves to fix the packing 43 and ensure that the packing 43 is closely attached to the spline shaft 6 and effectively prevents leakage.

[0059] On the basis of the above embodiment, referring to Figure 3 The support sealing group 4 further comprises an O-shaped sealing ring 46 which is arranged in the second mounting hole and closely attached to the outer circumferential surface of the spline shaft 6. The support sealing group 4 further comprises a gasket 47 which is arranged between the bushing 41 and the wall plate 5.

[0060] That is, the O-ring 46 is installed in the second mounting hole and tightly contacts the outer circumferential surface of the spline shaft 6, which prevents liquid from leaking from the gap between the spline shaft 6 and the bushing 41 and provides an additional sealing layer to ensure the sealing of the system. The gasket 47 is located between the bushing 41 and the wall plate 5. It can be used to adjust the gap between the bushing 41 and the wall plate 5 to ensure that the bushing 41 is properly tight when installed.

[0061] Specifically, an angle sensor is installed on the door leaf 1 or the lug plate assembly 7, which can monitor and feedback the rotation angle of the door leaf 1 in real time. The angle sensor is installed on the door leaf 1 or the lug plate assembly 7 directly connected thereto. It is ensured that the sensor can be stably fixed and will not be disturbed by other components. The output signal line of the angle sensor is connected to the input interface of the controller. It can be realized by wired or wireless mode, ensuring stable and reliable signal connection. The input parameters of the angle sensor are configured in the controller, including signal type, range, resolution, etc. The target angle of the door leaf rotation is set to 90°, and the corresponding control logic is configured. For example, when the sensor detects that the door leaf rotates to 90°, the controller sends a signal to stop the hydraulic cylinder 9.

[0062] Gate opening process:

[0063] First, start the hydraulic cylinder 9 to extend the piston rod, which in turn drives the crank arm 8 to rotate counterclockwise. The counterclockwise rotation of the crank arm 8 through the second inner spline thereon cooperates with the second outer spline 62 on the spline shaft 6, which makes the spline shaft 6 also rotate counterclockwise. The counterclockwise rotation of the spline shaft 6 through the cooperation of the first outer spline 61 with the first inner spline in the lug plate assembly 7 drives the lug plate assembly 7 to rotate. Finally, the counterclockwise rotation of the lug plate assembly 7 drives the door leaf 1 to rotate counterclockwise through the lug plate 71. When the door leaf 1 rotates counterclockwise by 90°, the door leaf 1 is in a horizontal state, and thus the gate is in an open state.

[0064] Gate closing process:

[0065] First, start the hydraulic cylinder 9 to retract the piston rod, which in turn drives the crank arm 8 to rotate clockwise. The clockwise rotation of the crank arm 8 through the second inner spline thereon cooperates with the second outer spline 62 on the spline shaft 6, which makes the spline shaft 6 also rotate clockwise. The clockwise rotation of the spline shaft 6 through the cooperation of the first outer spline 61 with the first inner spline in the lug plate assembly 7 drives the lug plate assembly 7 to rotate. Finally, the clockwise rotation of the lug plate assembly 7 drives the door leaf 1 to rotate clockwise through the lug plate 71. When the door leaf 1 rotates clockwise by 90°, the door leaf 1 is in a vertical state, and thus the gate is in a closed state.

[0066] In conclusion, the driving device of the working gate of the gate head provided by the utility model can drive the rotation of the crank arm through the adjustment of the extension and retraction speed and stroke of the hydraulic oil cylinder by receiving the control signal from the outside through the controller, and then drive the rotation of the spline shaft, and then convert the rotation of the spline shaft into the opening and closing action of the gate leaf through the ear plate assembly, so that the opening and closing of the gate is realized. In conclusion, the driving device of the working gate of the gate head provided by the utility model can realize the opening and closing action of the gate leaf through the cooperation of the supporting assembly, the supporting sealing group, the spline shaft, the ear plate assembly, the crank arm and the hydraulic oil cylinder, so that the structure is simple, the maintenance is convenient, the reliability of long-term operation of the gate is ensured, and reliable guarantee is provided for the operation of the water conservancy project.

[0067] The above only is the preferred embodiment of the application, and does not limit the application, and any modification, equivalent replacement and improvement made within the spirit and principle of the application should be included in the protection scope of the application.
