Description
Technical Field
[0001] The utility model relates to the technical field of inclined lifting appliances, and more specifically, to an inclined lifting appliance structure for a quay crane. Background Art
[0002] To reduce environmental pollution and improve transportation efficiency, more and more bulk goods such as coal, grain, and ore are loaded and transported on the road using enclosed and efficient containers. To reduce the cost of waterway transportation, after the containers loaded with bulk goods arrive at the terminal, the bulk goods in the containers need to be unloaded onto the ships docked at the quay crane front of the terminal. For a long time, such bulk goods have been loaded into the cabin through conveyor belts and ship loaders, which is costly and complex in loading and unloading. Conventional container lifting appliances at the quay crane front only have the function of horizontally moving containers and do not have the tilting function, and cannot directly dump the bulk goods contained in the containers onto the ship. Therefore, there is an urgent need to develop a tilting lifting appliance that can tilt at the quay crane front to directly dump the bulk goods contained in the container through the side door onto the ship, and for this purpose, an inclined lifting appliance structure for a quay crane is proposed.
[0003] Most of the existing inclined lifting appliances for quay cranes use ropes to tow containers and tilt the containers to pour materials onto the cabin. As is well known, the wind speed at the quay crane is relatively high, resulting in the container shaking in the air and posing a safety hazard. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides an inclined lifting appliance structure for a quay crane, and the technical problem to be solved is that when the container is towed by a rope, it is prone to shaking when encountering wind and current, posing a safety hazard.
[0005] To achieve the above object, the utility model provides the following technical solution: an inclined lifting appliance structure for a quay crane, including an upper support plate:
[0006] The lower end of the upper support plate is fixedly provided with a hinged frame, the outer surface of the hinged frame is hinged with a rotating block, and the lower end of the rotating block is fixedly provided with a lower support plate;
[0007] A rope recovery device capable of pulling the container is arranged inside the rotating block for pulling the container closer to the lower support plate;
[0008] The rope recovery device includes a bidirectional motor, the bidirectional motor is fixedly arranged inside the rotating block, the output ends of the bidirectional motor respectively penetrate through both sides of the rotating block, and the output ends of the bidirectional motor are respectively fixedly provided with recovery discs;
[0009] An angle tilting device capable of tilting the lower support plate is arranged between the upper support plate and the lower support plate for adjusting the tilting angle of the lower support plate.
[0010] In a preferred embodiment, four rope grooves are formed inside the lower support plate, and fixed pulleys are respectively and movably arranged inside the four rope grooves.
[0011] In a preferred embodiment, a towing rope is movably arranged on the outer surface of the fixed pulley, and the upper end of the towing rope is fixedly connected to the outer surface of the recovery disc.
[0012] In a preferred embodiment, the angle inclination device includes a first hinge seat, and the first hinge seat is fixedly arranged at the lower end of the upper support plate.
[0013] In a preferred embodiment, a second hinge seat is fixedly arranged at the upper end of one side of the lower support plate.
[0014] In a preferred embodiment, a cylinder is fixedly arranged at the movable end of the first hinge seat, and the output end of the cylinder is fixedly connected to the movable end of the second hinge seat.
[0015] In a preferred embodiment, two driving motors are fixedly arranged at the upper end of the upper support plate, and moving wheels are respectively and fixedly arranged at the output ends of the two driving motors. The moving wheels are located inside the track at the output end of the crane, and heat dissipation holes are formed on both sides of the rotating block.
[0016] The technical effects and advantages of the present utility model:
[0017] 1. By starting the bidirectional motor of the present utility model, the two recovery discs are driven to rotate, so that the towing rope is recovered. Since the lower end of the towing rope is hooked and hung on the four corners of the container, the container can be driven to move upward, so as to approach the lower support plate. When the container approaches the lower support plate, the fixed pulley can tighten the towing rope, thereby avoiding the problem that the strong airflow blows the container to shake.
[0018] 2. By the telescopic movement of the cylinder of the present utility model, using the connection between the first hinge seat and the second hinge seat, the lower support plate and the rotating block can be pulled to rotate around the articulated frame, so that the effect of inclining the container can be realized, and thus the materials in the container can be dumped on the cabin.

Specific embodiments
[0026] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art of this inclined lifting device field without creative efforts based on the embodiments of this utility model belong to the scope protected by this utility model.
[0027] As Figure 1 and 2 shown, this utility model provides an inclined lifting device structure for a quay crane, including an upper support plate 1: An articulated frame 7 is fixedly provided at the lower end of the upper support plate 1. A rotating block 8 is hinged to the outer surface of the articulated frame 7. A lower support plate 4 is fixedly provided at the lower end of the rotating block 8. Two drive motors 5 are fixedly provided at the upper end of the upper support plate 1. Moving wheels 6 are respectively fixedly provided at the output ends of the two drive motors 5. The moving wheels 6 are located inside the output end track of the crane. Heat dissipation holes 9 are provided on both sides of the rotating block 8.
[0028] In order to avoid the container from shaking due to the blowing of a strong air current, a rope recovery device 2 capable of pulling the container is provided inside the rotating block 8, which is used to pull the container closer to the lower support plate 4;
[0029] As Figure 3 shown, the rope recovery device 2 includes a bidirectional motor 21. The bidirectional motor 21 is fixedly arranged inside the rotating block 8. The output ends of the bidirectional motor 21 penetrate through both sides of the rotating block 8 respectively. Recovery discs 22 are fixedly arranged at the output ends of the bidirectional motor 21 respectively. Four rope grooves 25 are formed inside the lower support plate 4. Fixed pulleys 23 are movably arranged inside the four rope grooves 25 respectively. A traction rope 24 is movably arranged on the outer surface of the fixed pulley 23. The upper end of the traction rope 24 is fixedly connected to the outer surface of the recovery disc 22. By starting the bidirectional motor 21, the two recovery discs 22 are driven to rotate, so that the traction rope 24 is recovered. Since the lower end of the traction rope 24 is hooked and hung on the four corners of the container, the container can be driven to move upward, so as to be closer to the lower support plate 4. When the container approaches the lower support plate 4, the traction rope 24 can be tightened by the fixed pulley 23, thus avoiding the problem of the container shaking due to the blowing of a strong air current.
[0030] Furthermore, in order to be able to tilt the container and pour the materials in the container onto the ship's hold, an angle tilting device 3 capable of tilting the lower support plate 4 is provided between the upper support plate 1 and the lower support plate 4, which is used to adjust the tilting angle of the lower support plate 4;
[0031] As Figure 4 shown, the angle tilting device 3 includes a first hinge seat 31. The first hinge seat 31 is fixedly arranged at the lower end of the upper support plate 1. A second hinge seat 33 is fixedly arranged at the upper end of one side of the lower support plate 4. The movable end of the first hinge seat 31 is fixedly provided with a cylinder 32. The output end of the cylinder 32 is fixedly connected to the movable end of the second hinge seat 33. By the telescopic movement of the cylinder 32 and using the connection between the first hinge seat 31 and the second hinge seat 33, the lower support plate 4 and the rotating block 8 can be pulled to rotate around the articulated frame 7, so that the effect of tilting the container can be achieved, and thus the materials in the container can be poured onto the ship's hold.
[0032] The working principle is as follows: When the present utility model is in use, the moving wheels 6 at the upper end of the present utility model are placed into the track at the output end of the crane, and the driving motor 5 can be used to move the present utility model within the track. When it is necessary to hitch the container, the hook lock at the lower end of the towing rope 24 is hitched to the hitching rings at the four corners of the container, and the towing rope is retracted by the rope recovery device 2 until the container approaches the lower support plate 4, thereby avoiding the problem of the container shaking due to strong air flow and making the container move more safely. When the container approaches the lower support plate 4, the driving motor 5 and the moving wheels 6 are used to move the present utility model to the upper end of the cabin, and the angle tilting device 3 is used to tilt the container, so as to pour the materials in the container onto the cabin, which overall improves the safety of the container when it is suspended in the air and improves the practicability of the present utility model.
[0033] In addition, it is worth noting that the control processes of electronic devices such as the driving motor 5, the bidirectional motor 21, and the cylinder 32 in the present utility model are all realized by the controller. The control circuit and structure of this controller belong to the mature prior art, and the controller is installed in the crane control room, so no further description is made in the present utility model.
[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
