[0039] Please refer to Figure 3 , Figure 3 This is a schematic structural diagram of a follow-up support provided by an embodiment of the present application.

[0040] The follow-up support 114 includes a bottom plate 1141, side plates 1142, and an enclosing cover plate 1143.

The limiting wheel seat 1212 includes a fixed end, a movable end, and a wheel shaft connecting member 12121. The fixed end is fixedly connected to the slider backing plate 113. The movable end is rotatably connected to a support member 1144 on the frame, i.e., the surrounding cover plate 1143, through a rotating shaft. The first fixed surface is perpendicular to the upper surface of the slider backing plate 113 and parallel to the movement direction of the rope.

Figure 5 which is a schematic assembly structure diagram of a limiting wheel seat from the second perspective provided by an embodiment of the present application.

[0044] The wheel shaft connecting member 12121 of the limiting wheel seat 1212 can be composed of a top plate and a bottom plate provided with through holes between the fixed end and the movable end, and the fixed end and the movable end are enclosed by side plates. A receiving space for the limiting wheel 1211 is left between the top plate and the bottom plate. The center of the limiting wheel 1211 passes through the through holes between the top plate and the bottom plate through a rotating shaft.

[0045] Please refer to Figure 6 , Figure 6 which is a schematic structure diagram of a limiting adjustment assembly provided by an embodiment of the present application.

[0046] The limiting adjustment assembly 122 includes a limiting adjustment member 1221, a slide rod 1222, and a spring. The limiting adjustment member 1221 is arranged on a second fixed surface connected to the first fixed surface. The second fixed surface is perpendicular to the first fixed surface and the upper surface of the slider backing plate 113. One end of the slide rod 1222 is rotatably connected to the movable end through a rotating shaft. The axial direction of the rotating shaft is parallel to the first fixed surface. The second end of the slide rod 1222 is connected to the limiting adjustment member 1221. The spring is arranged on the surface of the slide rod 1222. The limiting adjustment member 1221 is used to adjust the length of the spring.

[0047] Optionally, the above-mentioned limiting adjustment member 1221 can be a limiting nut.

[0048] Please continue to refer to Figure 1 and Figure 2 , the shore bridge follow-up mechanism 10 can also be provided with a detection and adjustment device on the support device 11. The detection and adjustment device is used to carry a rope detection device and adjust the relative position between the rope detection device and the rope.

[0049] Optionally, the detection and adjustment device includes an optical axis 141 and a slider 142. The optical axis 141 is disposed on the support device 11 and is perpendicular to the movement direction of the rope. The slider 142 is arranged on the optical axis 141 and is used to carry the rope detection device.

[0050] Among them, the rope detection device can be a rope flaw detection device, etc. The rope in this embodiment can be a steel wire rope.

[0051] Optionally, the slider 142 is a lead screw nut slider.

[0052] The wear indication device 13 includes a wear pointer 131 disposed on the follower device 12 and a wear mark 132 disposed on the support device 11. The wear pointer 131 is used to point to the corresponding position of the wear mark 132 when the rope stopper 121 is displaced due to wear.

[0053] Specifically, the wear pointer 131 is arranged on the limit wheel seat 1212, and the wear mark 132 is arranged on the outer surface of the first base 111 parallel to the upper surface of the slider backing plate 113. For example, the wear mark 132 is arranged on the outer surface of the top plate of the first shield 115.

[0054] Optionally, a rope center pointer 151 is arranged on the second base 112 of the quay crane follower mechanism 10 in this embodiment, and a rope center mark 152 is arranged on the outer surface of the top plate of the third shield 117 parallel to the slider backing plate 113.

[0055] The working principle of the quay crane follower mechanism 10 is described below. When the rope shakes, the force is transmitted to the limit wheel 1211. The spring on the sliding rod 1222 is compressed to play a shock absorption and buffering role for the limit wheel 1211. The rotating shaft enables the limit wheel 1211 to move around the rotating shaft, restricting the movement freedom of the limit wheel 1211 in other directions, so that the rope is in the correct and appropriate position, thereby enabling the follow-up function of the rope and the follower device 12 for detection operations, etc. At the same time, after the limit wheel 1211 wears during use, regularly adjust the limit adjustment component 1221 through maintenance to adjust the length of the spring, so that the spring has a certain compression amount and maintains the pre-tightening force of the spring, thereby playing a supporting role for the limit wheel 1211 and avoiding damage to equipment such as the rope detection device caused by rope oscillation through the follower device 12.

[0056] The detection and adjustment device is supported by linear bearings and can move horizontally left and right on the optical axis 141. The position of the slider 142 on the detection and adjustment device is adjusted by the bolt and nut to move the position of the slider 142 horizontally left and right, so that the detection and adjustment device is in a suitable position, ensuring the smooth progress of operations such as rope detection using the rope detection device.

[0057] The wear pointer 131 is connected to the limit wheel seat 1212 and moves synchronously with the limit wheel 1211 and the limit wheel seat 1212. When the limit wheel 1211 is worn due to long-term operation, it will continue to fit the rope and generate displacement. Through the relative position between the wear pointer 131 and the wear mark 132, maintenance personnel can discover it in time, and then perform corresponding maintenance on the entire shore bridge follow-up mechanism 10 to ensure the safety of the detection equipment and the rope and ensure the smooth progress of the rope operation.

[0058] It should be understood that in addition to being applicable to the lifting cableway, the shore bridge follow-up mechanism 10 in this embodiment can also be applied to fields that require wire rope limit, such as mines, oil industry equipment, port transportation equipment, and drilling platform equipment.

[0059] In summary, the embodiment of the present application provides a shore bridge follow-up mechanism 10, which includes a support device 11, a follow-up device 12, and a wear indication device 13. The follow-up device 12 is arranged on the support device 11 along the movement direction of the rope, and the wear indication device 13 is arranged on the follow-up device 12 and the support device 11; the follow-up device 12 includes a rope limit member 121 and a limit adjustment assembly 122. The rope limit member 121 is movably connected to the limit adjustment assembly 122. The rope limit member 121 is used to limit the rope, and the limit adjustment assembly 122 is used to limit the degree of freedom of movement of the rope limit member 121 except in the specified movement direction; the wear indication device 13 includes a wear pointer 131 arranged on the follow-up device 12 and a wear mark 132 arranged on the support device 11. The wear pointer 131 is used to point to the corresponding position of the wear mark 132 when the rope limit member 121 is displaced due to wear.

[0060] In the above implementation manner, the support of the follow-up device 12 avoids the damage to the equipment caused by the rope oscillation. At the same time, the cooperation between the wear indication device 13 and the follow-up device 12 can realize the visual indication of the wear of the rope limit member 121. The current wear condition of the rope limit member 121 in the follow-up device 12 can be known through the wear indication device 13, so as to perform corresponding inspection and maintenance, ensuring the stability and safety of the rope operation.
