Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment technology, and in particular to an anti-swaying device for garbage hoisting equipment. Background Technology

[0002] In modern waste treatment plants (such as waste incineration plants or waste transfer stations), garbage cranes (or garbage hoists) are indispensable core equipment. Their main function is to use a bridge crane that can move in three-dimensional space to drive a huge grab bucket (or gripper) to grab and mix garbage in the garbage storage pit, and then accurately transfer a certain amount of garbage to the feeding port and send it to the subsequent processing system (such as the incinerator).

[0003] Currently, these types of garbage cranes generally face a long-standing technical problem during operation: severe shaking of the grab bucket during movement. Specifically, when the trolley (bridge) or crane starts or brakes at high speed along the track, the grab bucket suspended below by steel cables will sway and shake due to enormous inertia. This shaking phenomenon leads to a series of serious operational problems and production hazards: 1. Poor positioning accuracy impacts automated operation efficiency: Automated and high-precision grabbing and feeding are the development trend of modern garbage cranes. However, the continuous shaking of the grab bucket makes it difficult for operators (or the automatic control system) to accurately judge its instantaneous position. During grabbing, the shaking may cause the grab bucket to fail to accurately align with the predetermined grab point, instead impacting the hard surface of the garbage pile, which not only reduces grabbing efficiency but also impacts the equipment structure. During feeding, the shaking grab bucket cannot accurately align with the narrow feeding port, causing garbage to be scattered around the feeding port. To complete the feeding, the operator must spend extra time repeatedly "centering" and fine-tuning, waiting for the shaking to naturally subside, which seriously slows down the operation cycle and reduces overall processing efficiency.

[0004] 2. Material spillage leads to unstable grabbing volume and environmental problems: During movement, the grab bucket's swaying creates a pendulum-like motion. This motion causes garbage already grabbed in the grab bucket to be thrown out, resulting in material spillage along the way. This not only reduces the actual amount of garbage fed into the system compared to expectations, affecting the incinerator's feeding stability and combustion efficiency, but more seriously, the spilled garbage falls into the garbage storage pit's channels, platforms, or other equipment, causing secondary pollution, increasing the difficulty and workload of cleaning and maintenance, and potentially breeding flies and mosquitoes, producing odors, and deteriorating the working environment.

[0005] 3. Equipment Wear and Safety Hazards: Long-term, uncontrolled swaying will subject the wire rope, hoisting mechanism, and connecting components to additional alternating stress, accelerating their fatigue and wear, and shortening the equipment's service life. Furthermore, a several-ton grab bucket swinging uncontrollably and violently above the storage pit is itself a significant safety hazard, threatening the safety of the equipment and personnel below.

[0006] Therefore, existing garbage cranes have significant shortcomings in preventing swaying, which directly restricts the operating efficiency, automation level, and environmental sanitation of garbage treatment stations. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides an anti-sway device for garbage lifting rolls. This design effectively solves the problem that existing garbage lifting rolls will sway during operation, resulting in poor positioning accuracy of the lifting claws and unstable material gripping.

[0008] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a main beam, a crossbeam slidably connected to the main beam, a hanger slidably connected to the crossbeam, a hanging rope assembly on the hanger, a hanging platform fixedly connected below the hanging rope assembly, a hanging coil fixedly connected below the hanging platform, balance blocks fixedly connected to both sides of the hanging platform, a balance line group fixedly connected to the balance blocks, a winding roller at the other end of the balance line group, the winding roller being rotatably connected to the hanger, and an adjusting bracket rotatably connected to the hanger for adjusting the traction angle of the balance line group.

[0009] Preferably, the hoisting rope assembly includes a winch on which hoisting ropes are wound. There are four sets of hoisting ropes, and each end of the four sets of hoisting ropes is fitted with a roller. Two sets of T-shaped connecting blocks are fixedly connected to the hoisting platform, and the rollers are rotatably connected to the connecting blocks.

[0010] Preferably, the balance line group includes two symmetrically distributed traction ropes, the traction ropes are fixedly connected to the middle of the lifting platform, and a guide wire is fixedly connected to the outside of the lifting block, the guide wire having a through hole for the traction rope to pass through.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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.

[0021] Please see the appendix Figure 1-4This embodiment discloses an anti-sway device for garbage hoisting rolls: a hoisting rope assembly 4 includes a winch 401 fixed to a hoisting frame 3, with four sets of hoisting ropes 402 wound on the winch 401. Each of the four sets of hoisting ropes 402 has a roller at its end. A hoisting platform 5 is connected below the hoisting rope assembly 4 via the rollers. Specifically, two sets of T-shaped connecting blocks 403 are fixedly connected to the hoisting platform 5, and the rollers are rotatably connected to the connecting blocks 403 via a rotating shaft. This four-point flexible connection method ensures the load-bearing stability of the hoisting platform 5 while allowing it to swing within a certain range. A hoisting roll 6 is fixedly connected below the hoisting platform 5 via a flange or welding. Multiple grippers 11 are hinged around the bottom of the hoisting roll 6 via a rotating shaft. Hydraulic rods 12 are respectively provided between the multiple grippers 11 and the shell of the hoisting roll 6, and all hydraulic rods 12 are synchronously extended and retracted through a hydraulic system to ensure that all grippers 11 can open and close synchronously, stably gripping or releasing garbage.

[0022] The core of this application lies in the anti-sway system, which is used to actively suppress the swaying of the lifting system composed of the lifting platform 5, the lifting coil 6, and the gripper 11. Balance blocks 7 are fixedly connected to both sides of the lifting platform 5. The function of the balance blocks 7 is to lower the center of gravity of the entire lifting system, increase stability, and also serve as the connection base for the balance line group 8.

[0023] The balancing line group 8 includes two symmetrically distributed traction ropes 801. Preferably, the traction ropes 801 are made of high-strength steel wire rope. One end of each traction rope 801 is fixedly connected to the middle of the lifting platform 5. To guide and protect the traction ropes 801, a guide wire 802 is fixedly connected to the outside of the balancing block 7. The guide wire 802 has through holes for the traction ropes 801 to pass through.

[0024] The other end of the traction rope 801 extends upward and is fitted with a winding roller 9. The winding roller 9 is rotatably connected to the hanger 3 via a bearing seat and is driven by a servo motor. By precisely controlling the winding length and speed of the winding roller 9 through the servo motor, a controllable tension can be applied to the traction rope 801.

[0025] An adjusting bracket 10 is rotatably connected to the hanger 3 for adjusting the traction angle of the balance line group 8 (traction rope 801) to cope with swaying in different directions. Specifically, the adjusting bracket 10 includes a support rod 1001, which is rotatably connected to the hanger 3 via a hinged seat. A telescopic rod 1002 is hinged to one end of the support rod 1001, and the other end of the telescopic rod 1002 is connected to another hinged seat mounted on the hanger 3. The telescopic rod 1002 is preferably an electrically or hydraulically driven linear actuator. A limiting rod 1003 is hinged together on the telescopic rod 1002 and the support rod 1001, and a fixed pulley 1004 that cooperates with the traction rope 801 is sleeved on the limiting rod 1003. After the traction rope 801 is led out from the winding roller 9, it passes over this fixed pulley 1004 and then passes downward through the guide wire 802 to connect to the hanging platform 5. By controlling the extension or retraction of the telescopic rod 1002, the support rod 1001 and the limiting rod 1003 can be pushed or pulled, thereby changing the position of the fixed pulley 1004 and realizing precise and active adjustment of the rope exit angle (i.e., traction direction) of the traction rope 801.

[0026] To enhance the gripping ability of the gripper 11 and prevent waste from slipping and falling off during gripping and transportation, an anti-slip strip 13 is provided on the inner side of the end of the gripper 11. The anti-slip strip 13 can be made of materials with a high coefficient of friction, such as rubber, polyurethane, or a metal strip with serrated edges.

[0027] The overall working process of this utility model is as follows: When the trolley (main beam 1) or the trolley (crossbeam 2) starts or brakes, the lifting platform 5 and the lifting coil 6 and gripper 11 below it will swing laterally (such as in the X or Y direction) due to inertia.

[0028] Sway detection: The system uses angle sensors or vision recognition systems (not shown in the figure) installed on the gantry 3 or platform 5 to detect the sway direction and amplitude of the hoisting system in real time.

[0029] Active suppression: The control system immediately calculates based on the detected sway signal and issues a command: The servo motor controlling the winding roller 9 operates to appropriately wind or release the traction rope 801 on the side where the swaying occurs, applying a pulling force opposite to the swaying direction. For example, if the platform 5 swings to the right, the winding roller 9 on the right side is controlled to wind up the rope appropriately, generating a pulling force to the left to counteract its swaying kinetic energy.

[0030] At the same time, the telescopic rod 1002 of the control adjustment bracket 10 is moved to adjust the position of the fixed pulley 1004, thereby changing the traction angle of the traction rope 801, ensuring that the direction of the applied tension is always precisely opposite to the instantaneous sway direction, so as to achieve the optimal damping effect.

[0031] Results: Through the aforementioned active and adjustable tension control, the swaying energy of the lifting system can be quickly dissipated, allowing it to return to stability in a very short time. This ensures that the gripper 11 can be accurately positioned at both the gripping and descent points and remains stable during movement, greatly reducing debris spillage caused by swaying and improving operational efficiency and safety.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
