Description

Technical Field

[0001] The utility model relates to the field of port defense, in particular to a hydraulic locking device applied to a port defense system. Background Art

[0002] In a Chinese invention patent application with publication number CN116180679A, the inventors disclosed a port defense system, wherein a buoyancy assembly includes a locking portion, wherein a locking arm of the locking portion can extend into a locking hole of a column, thereby locking the buoyancy assembly and the column, preventing the buoyancy assembly from displacing relative to the column within the floating space between the two columns. The locking arm of the locking portion can exit the locking hole of the column, allowing the buoyancy assembly to displace relative to the column within the floating space between the two columns. Furthermore, the prior art locking portion includes a distance sensor, which is disposed on a drive unit of the locking portion and is used to detect whether the locking arm is horizontally aligned with the locking hole of the column. However, the prior art distance sensor is exposed, which makes it easily damaged by collisions. In addition, the existing technology is unable to detect whether the locking arm of the locking part is retracted into place. If the locking arm of the locking part is not retracted into place, the outermost end of the locking arm of the locking part will slightly hang on the edge of the column used to form the lock hole. In the process of the locking part moving up and down with the buoyancy component, the column will cause the outermost end of the locking arm of the locking part to tilt and be stressed, thereby damaging the locking part.

[0039] Refer to the attached drawings of the specification of this utility model Figures 1 to 10 In the following description, a hydraulic locking device for use in a port defense system according to a preferred embodiment of the present invention will be disclosed and explained. The hydraulic locking device includes a base 10, a hydraulic drive mechanism 20, two guide mechanisms 30, two locking elements 40 and two detection elements 50.

[0040] Specifically, the hydraulic drive mechanism 20 includes a hydraulic cylinder 21 and two telescopic arms 22. The hydraulic cylinder 21 has two cylinder chambers 211 and two cylinder channels 212. One cylinder channel 212 is connected to one cylinder chamber 211, and the other cylinder channel 212 is connected to the other cylinder chamber 211. The inner end 221 of one telescopic arm 22 extends into the corresponding cylinder cavity 211 through one of the cylinder body channels 212 of the hydraulic cylinder 21, and the inner end 221 of the telescopic arm 22 is configured to be able to move back and forth in the cylinder cavity 211 of the hydraulic cylinder 21, so that the telescopic arm 22 can switch between a retracted position and an extended position. Correspondingly, the inner end 221 of another telescopic arm 22 extends into the corresponding cylinder cavity 211 through another cylinder body channel 212 of the hydraulic cylinder 21, and the inner end 221 of the telescopic arm 22 is configured to be able to move back and forth in the cylinder cavity 211 of the hydraulic cylinder 21, so that the telescopic arm 22 can switch between a retracted position and an extended position.

[0041] In this specific example of the hydraulic locking device of the present invention, the two telescopic arms 22 of the hydraulic drive mechanism 20 move synchronously, that is, the two telescopic arms 22 can be synchronously switched from the retracted position to the extended position, and can also be synchronously switched from the extended position to the retracted position.

[0042] The hydraulic cylinder 21 of the hydraulic drive mechanism 20 is disposed in the middle of the base 10. Each of the guide mechanisms 30 is disposed at opposite ends of the base 10, and each of the guide mechanisms 30 has a guide hole 31.

[0043] It is worth noting that the specific manner in which the hydraulic cylinder 21 is disposed in the middle of the base 10 and the guide mechanism 30 is disposed at the end of the base 10 is not limited in the hydraulic locking device of the present invention. For example, in one specific embodiment of the hydraulic locking device of the present invention, the hydraulic cylinder 21 and the guide mechanism 30 are respectively locked to the middle and end of the base 10 via a screw and a nut.

[0044] Each locking element 40 has a driven end 41 and a locking end 42 facing each other, and further has a receiving cavity 43, a detection hole 44 and a threading notch 45 respectively connected to the receiving cavity 43. The detection hole 44 is formed on the end surface of the locking end 42, and the threading notch 45 is formed on the side of the driven end 41. The driven end 41 of each locking element 40 is drivably connected to the outer end 222 of each telescopic arm 22 of the hydraulic drive mechanism 20, and the locking end 42 of each locking element 40 is movably extended to the guide hole 31 of each guide mechanism 30, and the locking end 42 of the locking element 40 can extend outside the guide mechanism 30.

[0045] Reference Attachment Figure 6 and Figure 10 When the telescopic arm 22 of the hydraulic drive mechanism 20 extends and switches from the retracted position to the extended position, the telescopic arm 22 pushes the locking element 40 to extend synchronously. Under the guidance of the guide mechanism 30, the locking end 42 of the locking element 40 can extend into a locking hole 101 of a column 100, thereby locking the hydraulic locking device to the column 100. That is, the hydraulic locking device is prevented from moving relative to the column 100. Correspondingly, when the telescopic arm 22 of the hydraulic drive mechanism 20 retracts and switches from the extended position to the retracted position, the telescopic arm 22 pulls the locking element 40 to retract synchronously. Under the guidance of the guide mechanism 30, the locking end 42 of the locking element 40 can withdraw from the locking hole 101 of the column 100, thereby releasing the hydraulic locking device from the column 100. That is, the hydraulic locking device is allowed to move relative to the column 100.

[0046] During the process of the telescopic arm 22 of the hydraulic drive mechanism 20 extending and pushing the locking element 40 to extend synchronously, in order to ensure that the locking end 42 of the locking element 40 is aligned with the locking hole 101 of the column 100, the hydraulic locking device of the present invention accommodates the detection element 50 in the accommodating cavity 43 of the locking element 40, and the detection surface 51 of the detection element 50 faces the detection hole 44 of the locking element 40, and the wire 52 of the detection element 50 passes through the threading notch 45 of the locking element 40. During the process of the telescopic arm 22 of the hydraulic drive mechanism 20 extending outward and pushing the locking element 40 to extend outward synchronously, the detection element 50 detects the position of the locking hole 101 of the column 100 in real time. Only when the locking end 42 of the locking element 40 is aligned with the locking hole 101 of the column 100, the telescopic arm 22 of the hydraulic drive mechanism 20 continues to extend outward to ensure that the locking end 42 of the locking element 40 can extend into the locking hole 101 of the column 100. 1. When the locking end 42 of the locking element 40 deviates from the locking hole 101 of the pillar 100, the telescopic arm 22 of the hydraulic drive mechanism 20 stops extending outward. When the detection element 50 detects that the locking end 42 of the locking element 40 is aligned with the locking hole 101 of the pillar 100 again, the telescopic arm 22 of the hydraulic drive mechanism 20 continues to extend outward to ensure that the locking end 42 of the locking element 40 can extend into the locking hole 101 of the pillar 100. In this manner, the hydraulic locking device can ensure that the locking end 42 of the locking element 40 extends into the locking hole 101 of the pillar 100 and prevent the pillar 100 from colliding with the locking end 42 of the locking element 40.

[0047] Furthermore, in this specific example of the hydraulic locking device of the present invention, since the detection element 50 is housed in the housing cavity 43 of the locking element 40, the locking element 40 can protect the detection element 50 from being impacted, thereby facilitating the reliability of the hydraulic locking device. In other words, in this specific example of the hydraulic locking device of the present invention, the detection element 50 is concealed to prevent it from being impacted.

[0048] It is worth mentioning that the type of the detection element 50 is not limited in the hydraulic locking device of the present invention. Figures 1 to 10 In the specific example of the hydraulic locking device of the present invention shown, the detection element 50 may be a magnetic switch.

[0049] Reference Attachment Figure 1 、 Figure 3 、 Figure 5 、 Figure 6 and Figure 10 The hydraulic locking device also includes two detection components 60, each of which includes a magnetic ring 61 and two magnetic detectors 62. The magnetic ring 61 is mounted on the inner end 221 of the telescopic arm 22, and the two magnetic detectors 62 are respectively arranged on the hydraulic cylinder 21 at intervals. When the telescopic arm 22 is in the retracted position, the position of the magnetic ring 61 corresponds to the position of one of the magnetic detectors 62. When the telescopic arm 22 is in the extended position, the position of the magnetic ring 61 corresponds to the position of the other magnetic detector 62. In this way, based on the data fed back by the two magnetic detectors 62, it can be determined whether the telescopic arm 22 has reached the retracted position or the extended position. For example, when the magnetic detector 62 at a position close to the cylinder channel 212 of the hydraulic cylinder 21 detects the presence of the magnetic ring 61, it indicates that the telescopic arm 22 is in the extended position; when the magnetic detector 62 at a position far from the cylinder channel 212 of the hydraulic cylinder 21 detects the presence of the magnetic ring 61, it indicates that the telescopic arm 22 is in the retracted position; when both magnetic detectors 62 do not detect the presence of the magnetic ring 61, it indicates that the telescopic arm 22 has neither reached the retracted position nor the extended position.

[0050] Preferably, the inner end 221 of the telescopic arm 22 has a fitting groove 223, into which at least a portion of the magnetic ring 61 is embedded. This not only prevents the magnetic ring 61 from axially moving relative to the telescopic arm 22, but also reduces the protrusion of the magnetic ring 61 from the circumference of the telescopic arm 22, thereby facilitating a reduction in the size of the hydraulic drive mechanism 20. Preferably, the circumferential wall of the magnetic ring 61 is flush with the circumferential wall of the telescopic arm 22, that is, the magnetic ring 61 does not protrude from the circumferential wall of the telescopic arm 22.

[0051] It is worth mentioning that the type of the magnetic detector 62 is not limited in the hydraulic locking device of the present invention. Figures 1 to 10 In the specific example of the hydraulic locking device of the present invention, the magnetic detector 62 may be a reed switch or a Hall element.

[0052] It is worth mentioning that the manner in which the magnetic detector 62 is arranged on the hydraulic cylinder 21 is not limited in the hydraulic locking device of the present invention. Figures 1 to 10In this specific example of the hydraulic locking device of the present invention shown, the hydraulic cylinder 21 has four mutually spaced mounting grooves 213, and each of the magnetic detectors 62 is respectively installed in each of the mounting grooves 213 of the hydraulic cylinder 21, so that the magnetic detector 62 is arranged in the hydraulic cylinder 21.

[0053] Reference Attachment Figures 3 to 10 The hydraulic locking device further includes two connecting mechanisms 70, which are movably mounted on the outer end 222 of the telescopic arm 22, and the driven end 41 of the locking element 40 is fixedly mounted on the connecting mechanism 70, so that the driven end 41 of the locking element 40 is drivably connected to the telescopic arm 22 through the connecting mechanism 70. Since there are errors in the installation of the hydraulic cylinder 21, the guide mechanism 30 and the base 10, and the telescopic arm 22 can only reciprocate in the axial direction and the guide mechanism 30 limits the movement direction of the locking element 40 to be in the axial direction, when the telescopic arm 22 pushes or pulls the locking element 40 to move, in order to prevent the telescopic arm 22 from being subjected to a component force perpendicular to the axial direction of the telescopic arm 22, in this specific example of the hydraulic locking device of the present invention, the hydraulic locking device connects the driven end 41 of the locking element 40 to the outer end 222 of the telescopic arm 22 through the connecting mechanism 70, and requires that the connecting mechanism 70 be movably mounted on the outer end 222 of the telescopic arm 22. In order to movably mount the connecting mechanism 70 on the outer end 222 of the telescopic arm 22 of the hydraulic drive mechanism 20, in the attached Figures 1 to 10 In this specific example of the hydraulic locking device of the present invention shown, the outer end 222 of the telescopic arm 22 is a ball head, and one end of the connecting mechanism 70 has a ball socket 71 and an arm body channel 72 connected to the ball socket 71. The diameter of the telescopic arm 22 is smaller than the diameter of the arm body channel 72 of the connecting mechanism 70. The outer end 222 of the telescopic arm 22 extends into the ball socket 71 through the arm body channel 72 of the connecting mechanism 70 so that the ball head of the telescopic arm 22 is rotatably maintained in the ball socket 71 of the connecting mechanism 70. In this way, the connecting mechanism 70 can move in multiple directions relative to the outer end 222 of the telescopic arm 22.

[0054] Accordingly, in order to fix the other end of the connecting mechanism 70 to the driven end 41 of the locking element 40, Figures 1 to 10In this specific example of the hydraulic locking device of the present invention, the other end of the connecting mechanism 70 has a slot 73 and a mounting channel 74 smaller in size than the slot 73. The driven end 41 of the locking element 40 has a block 46 and a column 47 smaller in size than the block 46. The block 46 and column 47 of the locking element 40 are respectively mounted in the slot 73 and the mounting channel 74 of the connecting mechanism 70, thereby fixing the driven end 41 of the locking element 40 to the connecting mechanism 70. Preferably, the slot 73 of the connecting mechanism 70 is a square slot, and the block 46 of the locking element 40 is a square block. In this way, the hydraulic locking device can prevent the locking element 40 from rotating relative to the connecting mechanism 70, thereby preventing the wire 52 of the detection element 50 from being damaged.

[0055] Specifically, in the hydraulic locking device of the present invention, the connecting mechanism 70 includes an upper portion 75 and a lower portion 76. The upper portion 75 and the lower portion 76 are interlocked and assembled to form the ball socket 71, the arm channel 72, the latching groove 73, and the latching channel 74 of the connecting mechanism 70 between the upper portion 75 and the lower portion 76. By dividing the connecting mechanism 70 into the upper portion 75 and the lower portion 76, one end of the connecting mechanism 70 can be movably mounted to the outer end 222 of the telescopic arm 22, and the other end of the connecting mechanism 70 can be fixedly mounted to the driven end 41 of the locking element 40. The upper portion 75 and the lower portion 76 can be locked together by a set of screws and nuts.

[0056] Preferably, the upper portion 75 of the connecting mechanism 70 has a wire threading channel 751 that passes through opposite ends of the upper portion 75. The wire 52 of the detecting element 50 passes through the wire threading notch 45 of the locking element 40 and then passes through the wire threading channel 751 of the upper portion 75. In this way, the wire 52 of the detecting element 50 can be kept away from the guide mechanism 30, thereby preventing the wire 52 of the detecting element 50 from being damaged when the telescopic arm 22 pushes or pulls the locking element 40 to move. At the same time, because the locking slot 73 of the connecting mechanism 70 is a square slot and the locking block 46 of the locking element 40 is a square block, the locking element 40 can be prevented from rotating relative to the connecting mechanism 70, thereby preventing the wire 52 of the detecting element 50 from being damaged.

[0057] Reference Attachment Figure 7The hydraulic locking device also includes two pads 80. The pads 80 wrap around the ball head of the telescopic arm 22 and are located between the ball head of the telescopic arm 22 and the connecting mechanism 70 to prevent direct friction between the ball head of the telescopic arm 22 and the connecting mechanism 70. In a specific example of the hydraulic locking device of the present invention, the pads 80 may be made of a rubber material or a polymer material with excellent wear resistance. In a specific example of the hydraulic locking device of the present invention, to facilitate the pads 80 wrapping around the ball head of the telescopic arm 22, the pads 80 include two arc-shaped gaskets 81. After the two gaskets 81 are respectively attached to the different ends of the ball head of the telescopic arm 22, the connecting mechanism 70 is installed on the outer end 222 of the telescopic arm 22, thereby maintaining the pads 80 between the ball head of the telescopic arm 22 and the connecting mechanism 70.

[0058] In addition, refer to the attached Figures 1 to 5 The hydraulic locking device also includes a plurality of buffer elements 90, which can be made of rubber material, wherein the buffer elements 90 can be installed on the outside of the guide mechanism 30 through a set of screws. When the guide mechanism 30 is hit, the buffer elements 90 can absorb the vibration to reduce the force on the guide mechanism 30 and improve the stability of the hydraulic locking device.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
