Description

Technical Field

[0001] This utility model relates to the field of bridge crane technology, specifically to an open-loop anti-sway control device for bridge cranes. Background Technology

[0002] Bridge cranes are lifting equipment that spans across workshops, warehouses, and material yards for material handling. Because their ends rest on tall concrete pillars or metal supports, they resemble bridges. The bridge frame of a bridge crane runs longitudinally along rails laid on elevated structures on both sides, making full use of the space beneath the bridge frame for material handling without being obstructed by ground equipment. It is the most widely used and numerous type of lifting machinery.

[0003] The bridge frame is the basic component of a bridge crane, consisting of main beams, end beams, and walkways. The main beam spans the space between spans and can have various structural forms, such as box girder, truss, web plate, or circular tube. End beams connect to both ends of the main beam, and walkways with safety railings are installed on the outer sides of the two main beams. A trolley traveling mechanism is installed on the walkway on one side of the cab, and an auxiliary conductor rail is installed on the walkway on the other side to supply power to the trolley's electrical equipment. Guide rails are laid above the main beams for trolley movement. The entire bridge crane moves along the guide rails along the length of the workpiece, driven by the trolley traveling mechanism.

[0004] Currently, bridge cranes lack stabilizing devices for hooks and hooked items after lifting, causing significant swaying during movement. Improper operation can lead to excessive swaying and a risk of the crane falling, posing a safety hazard. Furthermore, uneven road surfaces can also cause swaying during crane movement. Therefore, an open-loop anti-sway control device for bridge cranes is needed to address these issues. Utility Model Content

[0005] To address the current issue that bridge cranes lack stabilizing devices for hooks and hooked items after lifting, resulting in significant swaying during movement, and the risk of falls due to excessive swaying when moved improperly, posing a safety hazard, and considering environmental factors such as uneven road surfaces during movement, this invention aims to provide an open-loop anti-sway control device for bridge cranes to solve the problems mentioned in the background.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An open-loop anti-sway control device for a bridge crane includes a main body, on the top of which a lifting assembly is fixedly connected;

[0012] As a preferred embodiment of this utility model, a second bearing seat is provided on the side of the mounting bracket, and the rotating rod extends into the interior of the second bearing seat.

[0013] As a preferred embodiment of this utility model, the mounting frame is provided with a protective shell, and the transmission wheel and rope wheel are disposed inside the protective shell.

[0014] As a preferred embodiment of this utility model, a first bearing seat is provided on the side of the mounting frame, and the output end of the rope wheel extends into the interior of the first bearing seat. There are two first bearing seats.

[0015] As a preferred embodiment of this utility model, a control box is fixedly connected to the side of the support frame, and a base plate is fixedly connected to the side of the ACF artificial cartilage pad, with casters provided at the bottom of the base plate.

[0027] In this embodiment, reference is made to Figure 1 , Figure 2 and Figure 3 As shown, the main body 1 includes a support frame 101, with a sliding groove 107 on the side of the support frame 101. An ACF artificial cartilage pad 102 is fixedly connected to the bottom of the support frame 101. The lifting assembly 2 includes a mounting frame 201, with a motor 202 mounted on the side of the mounting frame 201. A rotating rod 203 is fixedly connected to the output end of the motor 202. A rotating wheel 204 is fixedly connected to the side of the rotating rod 203. A transmission wheel 205 is meshed with the side of the rotating wheel 204. A rope wheel 206 is fixedly connected to the side of the transmission wheel 205. A steel wire rope 208 is fixedly connected to the bottom of the rope wheel 206. The bottom of the steel wire rope 208 is fixedly connected to... A load-bearing ring 209 is attached, and a buckle 217 is provided on the side of the load-bearing ring 209. A connecting rod 211 is fixedly connected to the side of the buckle 217, and a buckle rod 212 is fixedly connected to the side of the connecting rod 211. A nut 214 is threadedly connected to the output end of the buckle rod 212. By using the mutual pulling and limiting of the connecting rods 211 on both sides of the load-bearing ring 209, the hoisted items at the bottom of the hook 210 can be stabilized, thereby avoiding large swaying of the hook 210 when moving, improving the stability of the hook 210, enhancing its cargo carrying capacity, ensuring the safety of the hoisted items, and avoiding accidents caused by instability or slippage.

[0028] The bottom of the ACF artificial cartilage pad 102 is fixedly connected to a base plate 103. Four ACF artificial cartilage pads 102 and base plates 103 are provided. A hook 210 is fixedly connected to the bottom of the load-bearing ring 209. A pad 213 is provided on the side of the slide groove 107. A retaining rod 212 is located inside the slide groove 107. Two connecting rods 211, two retaining rods 212, and two nuts 214 are provided on the pad 213. A second bearing seat 215 is provided on the side of the mounting frame 201. A rotating rod 203 extends into the second bearing seat 215. A protective shell 216 is provided inside the mounting frame 201. A transmission wheel 205 and a rope wheel 206 are located inside the protective shell 216. The side of the mounting frame 201 is provided with a first bearing seat 207. The output end of the rope pulley 206 extends into the interior of the first bearing seat 207. There are two first bearing seats 207. The support frame 101 is supported by an ACF artificial cartilage pad 102, which can ensure the stability of the bridge crane when it moves as a whole. The ACF artificial cartilage pad 102 has extremely high energy absorption capacity and can absorb a large amount of impact energy, effectively reducing the impact of the bridge crane vibration on the surrounding structure and personnel. Compared with traditional rubber shock absorbers, the ACF artificial cartilage pad 102 requires less material and is smaller in size. It can better absorb ineffective kinetic energy, better carry out production, and better protect the safety of equipment and personnel.

[0029] In this embodiment, reference is made to Figure 1 and Figure 4 As shown, a control box 106 is fixedly connected to the side of the support frame 101, and a base plate 103 is fixedly connected to the side of the ACF artificial cartilage pad 102. A caster wheel 104 is provided at the bottom of the base plate 103, and an adjustable support foot 105 is provided at the bottom of the base plate 103. There are four casters wheel 104 and four adjustable support feet 105. The length can be freely adjusted by using the adjustable support feet 105, and the bridge crane can be flexibly adjusted for fixing or moving in conjunction with the casters wheel 104.

[0030] In this solution, an open-loop anti-sway control device for a bridge crane can be used to move the equipment to the hoisting position using the movable wheel 104, hook the item using the hook 210, and drive the rotating rod 203 to rotate using the motor 202. This causes the rotating wheel 204 and the transmission wheel 205 to mesh, and the control rope wheel 206 to wind up the wire rope 208, thereby lifting the item suspended on the hook 210. The connecting rods 211 on both sides of the load-bearing ring 209 pull and limit each other, which can stabilize the hoisted item at the bottom of the hook 210, thereby preventing the item suspended on the hook 210 from swaying too much during movement.
