[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] The purpose of this utility model is to provide a connection device for boarding bridge ports, which can hold the port and the connecting port in place by a safety pull rod when the connecting rod breaks, thereby preventing the port from falling and improving the safety of the boarding bridge port. Through the cooperation of the carrier plate and the positioning ring, the problem of radial displacement of the product during polishing is avoided, thus improving the polishing effect of the product.
[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] refer to Figures 1-5 The connecting device for the boarding bridge gate disclosed in this embodiment of the utility model includes: a connecting rod 1 and a safety rod 4. The first end of the connecting rod 1 is connected to the upper connecting plate 2 of the boarding bridge gate, and the second end of the connecting rod 1 is fixedly connected to the top plate 3 of the connecting port. The connecting rod 1 can provide the connection force required for the normal operation of the boarding bridge gate and the connecting port. The connection force includes, but is not limited to, tension, support, torsional force, and bending moment. A limit plate 5 is provided on the top plate 3 of the connecting port. The limit plate 5 has a through hole. The first end of the safety rod 4 is connected to the upper connecting plate 2, and the second end of the safety rod 4 passes through the through hole on the limit plate 5 and extends to the side of the limit plate 5 away from the boarding bridge gate. A limit block 6 is provided on the second end of the safety rod 4. The size of the limit block 6 is larger than the size of the through hole. The limiting block 6 and the limiting plate 5 are spaced apart. That is, after the second end of the safety lever 4 passes through the through hole, it extends a certain distance away from the boarding bridge in the direction of the limiting plate 5. When the connecting lever 1 is working normally, the limiting block 6 will not contact the limiting plate 5. At this time, the safety lever 4 is not subjected to tension or pressure. Once the connecting lever 1 breaks, the boarding bridge moves away from the connection port and pulls the limiting block 6 closer to the limiting plate 5. Since the through hole is small, it can prevent the second end of the safety lever 4 from coming out of the through hole of the limiting plate 5. The safety lever 4 provides tension to the boarding bridge connection port, pulling the boarding bridge connection port and the connection port together. This avoids the boarding bridge connection port falling due to the breakage of the connecting lever 1 and improves the safety of the boarding bridge.
[0032] In a preferred embodiment, a spring 7 is provided between the limiting block 6 and the limiting plate 5. When the limiting block 6 moves closer to the limiting plate 5, the spring 7 can provide a supporting force to the limiting block 6 in a direction away from the limiting plate 5, so as to slow down the moving speed of the limiting block 6 and play a buffering role.
[0033] Furthermore, the spring 7 is in a compressed state between the limiting block 6 and the limiting plate 5, so that the safety lever 4 can provide a certain pulling force to the boarding bridge gate before the connecting lever 1 breaks.
[0034] In a preferred embodiment, an alarm device is also included. A displacement sensor 8 is provided on the limit block 6, and the displacement sensor 8 is signal-connected to the alarm device. The displacement sensor 8 can monitor the movement state of the limit block 6. When the displacement sensor 8 detects that the amount of movement of the limit block 6 in the direction of the limit plate 5 reaches a preset value, it can send a signal to the alarm device to make the alarm device emit an audible and visual alarm.
[0035] In a preferred embodiment, a positioning rod 9 is also included. The first end of the positioning rod 9 is rotatably connected to the lower connecting plate 11 of the boarding bridge port via a first rotating shaft 10. The second end of the positioning rod 9 is connected to the bottom plate 12 of the connecting port. The first end of the connecting rod 1 and the first end of the safety rod 4 are both rotatably connected to the upper connecting plate 2 via a second rotating shaft 13. The first rotating shaft 10 and the second rotating shaft 13 are both vertically arranged and collinear, ensuring that the boarding bridge port can be rotated.
[0036] Preferably, two connecting rods 1 are provided, and the two connecting rods 1 are rotatably connected to the second rotating shaft 13 via a first adapter block 14 rotatably mounted on the second rotating shaft 13. By using the first adapter block 14 as an intermediate structure connecting the connecting rods 1 and the second rotating shaft 13, the two connecting rods 1 can be connected at the same height position on the second rotating shaft 13, ensuring the uniformity of force distribution on the two connecting rods 1 during operation and further improving the safety of the boarding bridge.
[0037] Even better, the connecting rod 1 is set horizontally, which minimizes the force on the connecting rod 1 under normal working conditions.
[0038] Those skilled in the art will understand that the connecting rod 1 can be configured with three, four, five, etc., according to actual needs.
[0039] In a preferred embodiment, the safety lever 4 is rotatably connected to the second rotating shaft 13 via a second adapter block 15 rotatably mounted on the second rotating shaft 13. The second adapter block 15 serves as an intermediate structure connecting the safety lever 4 and the second rotating shaft 13, allowing the safety lever 4 to connect to the connecting lever 1 at different heights on the second rotating shaft 13. This ensures that the connection positions of the second end of the safety lever 4 and the connecting port, as well as the connection positions of the second end of the connecting lever 1 and the connecting port, remain in a certain vertical direction. This ensures that even if the connecting lever 1 breaks, the direction of the tension force provided by the safety lever 4 to the boarding bridge remains consistent with the direction of the tension force provided by the connecting lever 1, avoiding sudden changes in the force direction that could cause the boarding bridge to tilt.
[0040] As a preferred embodiment, multiple safety levers 4 are provided. The second adapter block 15 enables multiple safety levers 4 to be connected at the same height position of the second rotating shaft 13, ensuring the uniformity of force on multiple safety levers 4 during operation.
[0041] Preferably, there are two safety levers 4, which are connected to the top plate 3 through two spaced limiting plates 5. The two limiting plates 5 and the second rotating shaft 13 are arranged in a triangle, which further improves the safety of the boarding bridge.
[0042] Furthermore, the second end of the connecting rod 1 and the second end of the safety rod 4 are both connected to the connection port through the limiting plate 5; preferably, the second end of the connecting rod 1 and the second end of the safety rod 4 are respectively connected to different height positions of the limiting plate 5 along a vertical direction.
[0043] More preferably, the safety lever 4 is arranged horizontally.
[0044] In a preferred embodiment, the connecting device further includes a third adapter block 19, through which the two safety levers 4 are respectively connected to the second adapter block 15.
[0045] Preferably, the rotation centers of the second rotating shaft 13, the third transition block 19, and the limiting plate 5 are not collinear. When two connecting rods 1 and two safety rods 4 are provided, and the two limiting plates 5 and the second rotating shaft 13 are arranged in a triangle, the third transition block 19 is set in the above form so that when the connecting rod 1 breaks, the tension provided by the two safety rods 4 to the boarding bridge is more concentrated, which is more conducive to the stability of the boarding bridge.
[0046] In a preferred embodiment, to further improve the safety of the boarding bridge gate, a reinforcing rod 16 is provided between the two limiting plates 5, with both ends of the reinforcing rod 16 connected to the two limiting plates 5 respectively. Preferably, a reinforcing rib is provided between the limiting plate 5 and the upper connecting plate 2. The above-mentioned configurations improve the stability of the limiting plate 5, achieving the technical effect of further improving the safety of the boarding bridge.
[0047] In a preferred embodiment, the lower connecting plate 11 is arc-shaped, and a track 17 is provided on the lower connecting plate 11. A drag wheel 18 is installed at the lower part of the connection port, and the drag wheel 18 abuts against the track 17. The first rotating shaft 10 is located at the center of the lower connecting plate 11. By using the combination of the drag wheel 18 and the track 17, the connection stability between the boarding bridge gate and the connection port is enhanced, while the stress on the positioning rod 9 and the connecting rod during operation is reduced.
[0048] Any adaptive changes made according to actual needs are within the protection scope of this utility model.
[0049] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that this utility model can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered as exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the utility model.
