Description

Technical Field

[0001] This application relates to the field of hoisting technology, and in particular to a hoisting device. Background Technology

[0002] When using lifting equipment to move materials, the observation range of the operators is limited due to factors such as location. Often, the materials or equipment are not perpendicular to the lifting boom or other lifting machinery before lifting. There is a possibility that the slings will tilt before lifting and the lifting equipment and materials will swing after lifting, which can easily cause injury to the operators and pose risks to the safety of equipment and property.

[0003] Therefore, improving the reliability of hoisting equipment and reducing the sway of the lifting equipment is an important research direction in the field of hoisting technology. Utility Model Content

[0004] This application provides a hoisting device that can reduce the risk of swinging collisions and improve reliability.

[0005] In a first aspect, this application provides a hoisting device, including a support beam, a drive component, a lifting device assembly, a detection component, and a controller. The support beam extends along a first direction and is movable along a second direction, the first direction intersecting the second direction. The drive component is movably connected to the support beam and is movable along the first direction. The lifting device assembly includes a first sling and a lifting device, the first sling connecting the lifting device and the drive component, the drive component driving the lifting device to rise and fall via the first sling. The detection component is disposed on the lifting device and is used to detect the angle between the first sling and the vertical direction. The controller is communicatively connected to the drive component and the detection component, respectively, the controller acquiring the angle and controlling the drive component to stop when the angle exceeds a first threshold.

[0006] In the technical solution of this application embodiment, a detection component is provided in the hoisting equipment. The detection component can detect the tilt of the sling and the lifting device, and control the drive component used to lift the lifting device to stop when the tilt is serious and the tilt angle exceeds a certain threshold, thereby reducing the possibility of the tilt angle increasing further or large swing after lifting, and improving the reliability of the hoisting equipment.

[0007] According to some embodiments of this application, the controller is used to lock the movement of the drive member along a first direction and the movement of the support beam along a second direction when the included angle exceeds a first threshold. Locking the lifting and lowering of the spreader assembly, as well as the movement of the drive member and the support beam, further reduces the possibility of collisions.

[0008] According to some embodiments of this application, the first threshold is α, where α ≤ 20°. Setting the threshold for triggering the drive to stop at a smaller angle further reduces the possibility of spreader swaying.

[0009] According to some embodiments of this application, the detection component includes a tilt sensor and / or a three-dimensional gyroscope. This enables the detection component to detect the tilt angle of the spreader assembly more accurately.

[0010] According to some embodiments of this application, the lifting device includes a hook and a connector. A first sling is detachably connected to the connector. A detection component is installed on the connector and spaced apart from the hook, and the detection component is also spaced apart from the first sling. This facilitates the installation of the lifting device assembly and reduces the possibility of interference to the detection component caused by the movement of the hook and the first sling.

[0011] According to some embodiments of this application, the lifting equipment further includes a damping stabilizer, which includes a mounting frame and a counterweight damper. The counterweight damper is installed within the mounting frame, and a first sling passes through the mounting frame. A drive unit is also used to drive the damping stabilizer to move up and down, and a controller is also used to control the damping stabilizer to descend when the included angle exceeds a second threshold, where the second threshold is less than or equal to a first threshold. The damping stabilizer with a certain weight can further reduce the sway of the lifting assembly and increase the speed of sway reduction.

[0012] According to some embodiments of this application, the detection component is disposed on the upper side of the lifting assembly. The detection component also includes a rangefinder. The detection component is further used to detect the distance between the damping stabilizer and the lifting assembly, and / or, the detection component is further used to detect the distance between the damping stabilizer and the drive component. By detecting the position and descent dimension of the damping stabilizer through the detection component, the accuracy of the lifting and lowering control of the damping stabilizer is improved.

[0013] According to some embodiments of this application, a positioning part is protruding from the lower side of the counterweight damper, and a base plate is provided at the lower end of the mounting bracket. The base plate has a positioning hole recessed along the thickness direction, and the positioning part extends at least partially into the positioning hole. The positioning hole restricts the swing of the counterweight damper, reducing the possibility of loosening or collision due to excessive swing amplitude, and mitigating the possibility of decreased shaking effect.

[0014] According to some embodiments of this application, at least a portion of the edge of the positioning part is spaced apart from the wall of the positioning hole, allowing the positioning part to move within the positioning hole. This gives the counterweight damping a certain degree of swing freedom, and the swing amplitude of the lifting assembly can be further reduced by swinging in the opposite direction to the lifting assembly.

[0015] According to some embodiments of this application, the damping stabilizer further includes a plurality of elastic elements disposed between the weight damper and the mounting frame. The elastic elements extend radially along the weight damper and are spaced apart circumferentially along the weight damper. The elastic elements are connected to the weight damper, or the elastic elements are connected to the mounting frame. The weight damper can also limit its own swing amplitude through the elastic elements.

[0016] According to some embodiments of this application, the mounting frame further includes at least one through hole extending in a direction, through which the first sling passes. The mounting frame has a through hole that matches the first sling, further defining the relative position of the mounting frame and the first sling, making the lifting and lowering of the damping stabilizer smoother.

[0017] According to some embodiments of this application, the first sling includes multiple segments connected in sequence, each segment of the first sling passing through a mounting frame. The mounting frame includes multiple through holes, with each segment of the first sling corresponding to one of the through holes. The multiple through holes are centrally symmetrically arranged relative to the central axis of the counterweight damper. This makes the damping stabilizer more uniformly and stably stressed.

[0018] According to some embodiments of this application, the detection component further includes a level. The level can correct the pose of the detection component, making its detection of the angle between the first sling and the vertical direction more accurate.

[0019] According to some embodiments of this application, the hoisting equipment also includes a speaker, which is communicatively connected to the controller. The speaker is used to issue an alarm signal when the included angle exceeds a first threshold. This allows the operator to be promptly informed of the sling tilt, further improving the reliability of the hoisting equipment. Attached Figure Description

[0039] When moving heavy or bulky materials, products, or equipment, lifting equipment is typically required. Lifting equipment usually includes support beams, drive components such as motors, slings, and lifting devices, with the lifting devices typically including hooks for connecting to the transported object. Operators using lifting equipment usually need to observe the position of the transported object and the connection between the object and the lifting devices from a height.

[0040] However, due to limitations imposed by the operator's location and surrounding equipment, the operator's field of vision is limited. It is usually impossible to accurately confirm whether the sling is parallel to the vertical direction or whether the angle between the sling and the vertical direction is small. There is a possibility that the sling will tilt significantly during lifting, and that the transported object and lifting equipment will swing after lifting. This could lead to the transported object and lifting equipment colliding with other equipment or personnel, thereby posing a risk of personnel injury and damage to the transported object during the transportation process.

[0041] In view of this, the present application provides a technical solution that, by setting a detection component for detecting the tilt of the sling in the lifting assembly, and controlling the operation or shutdown of the drive component according to the tilt condition, can conveniently and promptly control the drive component to stop when the sling tilts, thereby reducing the possibility of the lifting assembly and the transported object swinging, and thus improving the reliability of the lifting equipment.

[0042] Next, we will combine the appendix Figure 1 To be continued Figure 4 The structure of the hoisting equipment 100 is described.

[0043] Please refer to the following: Figures 1 to 3 , Figure 1 This is a schematic diagram of the structure of the hoisting equipment provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of the hoisting equipment provided in some other embodiments of this application. Figure 3 This is a schematic diagram of the structure of the detection component provided in some embodiments of this application.

[0044] In a first aspect, this application provides a hoisting device 100, including a support beam 10, a drive component 20, a lifting device assembly 30, a detection component 40, and a controller 50. The support beam 10 extends along a first direction X and is movable along a second direction Y, where the first direction X intersects with the second direction Y. The drive component 20 is movably connected to the support beam 10 and is movable along the first direction X. The lifting device assembly 30 includes a first sling 31 and a lifting device 32. The first sling 31 connects the lifting device 32 and the drive component 20, and the drive component 20 is used to drive the lifting device 32 to rise and fall via the first sling 31. The detection component 40 is disposed on the lifting device 32 and is used to detect the angle between the first sling 31 and the vertical direction. The controller 50 is communicatively connected to the drive component 20 and the detection component 40, respectively, and is used to acquire the angle and control the drive component 20 to stop when the angle exceeds a first threshold.

[0045] This application provides a hoisting device 100, including a support beam 10 for providing support, a drive component 20 for driving the lifting of a transported object, a lifting device assembly 30 for connecting to the transported object, a detection component 40 for detecting the status of the lifting device assembly 30, and a controller 50 for controlling the hoisting device 100 as a whole.

[0046] Specifically, the support beam 10 can be a beam-like structure extending in a straight line. The support beam 10 extends along a first direction X and can move in a second direction Y, wherein the first direction X and the second direction Y intersect and can be perpendicular to each other. The support beam 10 can be moved in the second direction Y by means of a slide rail, overhead crane, gantry, or other structural form. At the same time, there should be a certain amount of free height space below the support beam 10 to facilitate hoisting.

[0047] The drive unit 20 is movably connected to the support beam 10. Optionally, the drive unit 20 is located below the support beam 10 for connection to the lifting device assembly 30. The drive unit 20 is movable relative to the support beam 10 in its extension direction, i.e., the first direction X, to move the position of the transported object. The drive unit 20 may be a motor or similar device capable of outputting torque. Optionally, multiple drive units 20 may be simultaneously installed on the support beam 10 depending on the number and weight of the transported object to be lifted.

[0048] The lifting device assembly 30 includes a first sling 31 and a lifting device 32. The first sling 31 connects the drive unit 20 and the lifting device 32, and the lifting device 32 can be used to connect to the transported object. The first sling 31 may be made of metal to give it good structural strength. When connected to the drive unit 20, the first sling 31 may be wound into a preset receiving space by rotating the output end of the drive unit 20 to achieve the lifting and lowering of the lifting device 32. The lifting device 32 can be connected between the first sling 31 and the transported object to be lifted, and the lifting device 32 may be a hook 321, a connecting rod, a gripper, or other structural forms.

[0049] The detection component 40 is mounted on the lifting device 32 and can move, tilt, and swing synchronously with the lifting device 32. The detection component 40 is equipped with sensors that can detect parameters such as the tilt direction and tilt angle of its own position relative to the vertical direction, thereby obtaining the angle between the first sling 31 and the vertical direction. Optionally, the detection component 40 may also include a power supply component and a communication component to provide energy to the sensors and to enable communication between the detection component 40 and the controller 50, transmitting the information acquired by the sensors to the controller 50.

[0050] The controller 50 may be optionally mounted on the support beam 10 or other location convenient for maintenance and operation. The controller 50 may be directly connected to the drive component 20 and the detection component 40 via signal lines; alternatively, the controller 50 may be optionally remotely exchanging information with the detection component 40 and the drive component 20 via a signal transmitting module and a signal receiving module. Optionally, the controller 50 may be equipped with a human-machine interface to facilitate the adjustment of parameters such as the first threshold.

[0051] When using the hoisting equipment 100, the detection component 40 is set at the lifting device 32 and monitors the angle between the first sling 31 and the vertical direction in real time. Then, the angle parameter is transmitted to the controller 50. The controller 50 can determine the relative size relationship between the angle parameter and the first threshold through logic circuits such as comparators. When the angle parameter exceeds the first threshold, a signal is sent to the drive unit 20 to stop, that is, to stop the lifting operation of the transported object, thereby reducing the possibility of the transported object and the lifting device 32 swinging and colliding due to excessive tilt angle.

[0052] Optionally, if the machine stops before the transported object leaves the ground, the position of the support beam 10 and / or the drive component 20 can be moved to reduce the included angle to below the first threshold by changing the position of the upper end of the first sling 31. Then, the machine can be locked by engaging the stop lock of the drive component 20 and the machine can be lifted again. If the transported object is already in a suspended state above the ground, the position of the support beam 10 and the drive component 20 can be left unchanged. The swing of the transported object can be reduced to below the first threshold by natural weakening or other artificial intervention before the object can be lifted to the preset position.

[0053] In the technical solution of this application embodiment, a detection component 40 is provided in the hoisting equipment 100. The detection component 40 can detect the tilt of the sling and the lifting device 32, and control the drive component 20 used for lifting the lifting device 32 to stop when the tilt is serious and the tilt angle exceeds a certain threshold, thereby reducing the possibility of the tilt angle increasing further or large swing after hoisting, and improving the reliability of the hoisting equipment 100.

[0054] In some alternative embodiments, the controller 50 is used to lock the movement of the drive member 20 along the first direction X and the movement of the support beam 10 along the second direction Y when the included angle exceeds a first threshold.

[0055] Optionally, when the included angle value exceeds the first threshold, in addition to stopping the drive to lift, the movement of the drive member 20 along the first direction X and the movement of the support beam 10 along the second direction Y can also be locked simultaneously.

[0056] Specifically, while obtaining the angle between the first sling 31 and the vertical direction through the detection component 40, it can also optionally obtain the tilt direction of the first sling 31 relative to its initial position when it is naturally hanging down and not swaying. After the angle value exceeds a first threshold, the controller 50 can optionally lock the movement of the support beam 10 and the drive component 20 in the opposite direction to the tilt direction.

[0057] For example, taking the first direction X as the north-south direction and the second direction Y as the east-west direction, if the detection component 40 detects that the lifting component 30 is tilted to the northwest relative to its initial position and the tilt angle exceeds the first threshold, it can be selected to lock the movement of the support beam 10 to the east and the movement of the drive component 20 to the south, thereby reducing the possibility of increased swing amplitude due to movement.

[0058] By controlling the lifting and lowering of the lifting assembly 30 and the movement of the driving component 20 and the support beam 10, the possibility of collision can be further reduced.

[0059] In some optional embodiments, the first threshold is α, where α ≤ 20°.

[0060] Optionally, when using the hoisting equipment 100, the first threshold value for triggering shutdown can be changed by operating the controller 50. The value of the first threshold value can be set according to parameters such as the weight of the transported object and the length of the first sling 31. Let the first threshold value be denoted as α. α can be selected to be less than or equal to 20°, and more specifically, to be around 10°.

[0061] By setting the threshold for triggering the drive unit 20 to stop to a smaller angle, the swaying of the spreader assembly 30 can be detected more promptly, further reducing the possibility of damage to the spreader 32 and the transported goods due to the swaying of the spreader 32.

[0062] In some alternative embodiments, the detection component 40 includes a tilt sensor and / or a three-dimensional gyroscope 41.

[0063] The detection component 40 in the hoisting equipment 100 is used to obtain the angle between the first sling 31 and the vertical direction. Optionally, it is also used to obtain the direction of inclination of the first sling 31 relative to its initial position when it is not swinging and naturally hanging down. Therefore, the detection component 40 may include an inclination sensor and / or a three-dimensional gyroscope 41. Both sensors can be used to obtain the inclination direction and inclination angle of the location of the detection component 40, so that the detection component 40 can obtain the aforementioned angle parameters more accurately.

[0064] In some optional embodiments, the lifting device 32 includes a hook 321 and a connector 322, the first sling 31 is detachably connected to the connector 322, and the detection component 40 is installed on the connector 322 and spaced apart from the hook 321, and the detection component 40 is spaced apart from the first sling 31.

[0065] Optionally, the lifting device 32 for connecting with the transported object may further include a hook 321 and a connector 322, wherein the hook 321 is used to lift the transported object by means of a securing strap or other binding material, and the connector 322 is used to connect the first sling 31 and the hook 321. The connector 322 may be a structure close to the movable pulley, and the hook 321 may be connected to the pulley shaft. In embodiments where the pulley is provided with a protective shell, the hook 321 may be connected to the protective shell, so that the overall structure of the lifting device 32 is reliable and easy to install.

[0066] Based on this, the detection component 40 is disposed on the connector 322, and can be optionally disposed in a position that does not rotate or slide with the lifting of the lifting device 32, and the detection component 40 is spaced apart from the first sling 31 and the hook 321, so as to stabilize the position of the detection component 40 and reduce the possibility of interference between the detection component 40 and the first sling 31, hook 321 and other components during operation.

[0067] Optionally, the detection component 40 and the connector 322 can be connected by fasteners, welding, snap-fit, or other methods to stabilize the relative position between the detection component 40 and the connector 322 and reduce the possibility of inaccurate detection results due to tilting of the detection component 40.

[0068] This makes the lifting device assembly 30 easier to install, while reducing the possibility that the movement of the hook 321 and the first sling 31 may interfere with the detection assembly 40.

[0069] Please see Figure 4 , Figure 4 This is a cross-sectional structural schematic diagram of a damping stabilizer provided in some embodiments of this application. In some optional embodiments, the hoisting device 100 further includes a damping stabilizer 60, which includes a mounting frame 61 and a counterweight damper 62. The counterweight damper 62 is installed inside the mounting frame 61, and a first sling 31 passes through the mounting frame 61. The drive member 20 is also used to drive the damping stabilizer 60 to rise and fall, and the controller 50 is also used to control the damping stabilizer 60 to fall when the included angle exceeds a second threshold, wherein the second threshold is less than or equal to the first threshold.

[0070] Optionally, the hoisting equipment 100 may also be equipped with a damping stabilizer 60 to further reduce the swaying of the lifting device assembly 30. The damping stabilizer 60 includes a mounting frame 61 and a counterweight damper 62, wherein the counterweight damper 62 is mounted on the mounting frame 61. In addition, the hoisting equipment 100 may also include a second sling 63, which connects the mounting frame 61 and the drive member 20. The drive member 20 can raise and lower the damping stabilizer 60 through the second sling 63.

[0071] The first sling 31 and the second sling 63 may be made of the same or different materials. In embodiments where the materials are the same, since the mass of the damping stabilizer 60 is usually less than that of the transported object, the diameter of the second sling 63 may be smaller than that of the first sling 31 to reduce costs.

[0072] The damping stabilizer 60 includes a mounting frame 61 and a counterweight damper 62. The mounting frame 61 can optionally enclose a receiving space and house the counterweight damper 62 within this space, providing connection and protection functions through the mounting frame 61. The counterweight damper 62 is a suspended counterweight with a large mass, giving the damping stabilizer 60 a certain mass and making it less prone to swaying.

[0073] Optionally, in order for the damping stabilizer 60 to act on the first sling 31 and the lower lifting device 32, the mounting frame 61 can be sleeved on the first sling 31. Specifically, it can be configured by drilling a through hole in the mounting frame 61, connecting and setting a ring-shaped limiting structure, or allowing the first sling 31 to pass through the aforementioned receiving space, so that the damping stabilizer 60 can swing synchronously with the first sling 31 at its position during the descent.

[0074] In an embodiment equipped with a damping stabilizer 60, if the included angle detected by the detection component 40 exceeds the second threshold, the drive component 20 can be controlled to lower the damping stabilizer 60. Since the damping stabilizer 60 has a large mass, it can form a gravity support point in the middle of the first sling 31, which has a long vertical extension, and reduce the length of the swing arm during swinging, thereby reducing the swing amplitude of the lifting device 32 and the lowered transported object.

[0075] Optionally, the second threshold may be the same as or smaller than the first threshold, so as to reduce the sway by the damping stabilizer 60 first when the machine stops, thereby reducing the possibility of collision and the possibility of reduced hoisting efficiency due to the machine stop.

[0076] Alternatively, the first threshold and the second threshold can be used for judgment at different stages of hoisting. For example, before the transported object rises above the support surface, the judgment can be made based on the first threshold; if the judgment fails, the aforementioned shutdown or other processing methods are triggered. During transport, if the object sways due to external impact, environmental factors, hoisting position, etc., the judgment can be made based on the second threshold; if the judgment fails, the damping stabilizer 60 is lowered. Alternatively, both thresholds can be used simultaneously for judgment.

[0077] By setting up a damping stabilizer 60, the sway at the lifting device 32 can be further reduced, thereby further improving the reliability of the lifting equipment 100.

[0078] In some optional embodiments, the detection component 40 is disposed on the upper side of the lifting device assembly 30, and the detection component 40 also includes a rangefinder 42. The detection component 40 is also used to detect the distance between the damping stabilizer 60 and the lifting device assembly 30, and / or, the detection component 40 is also used to detect the distance between the damping stabilizer 60 and the drive member 20.

[0079] Optionally, the detection component 40 may also include a rangefinder 42. In an embodiment where the rangefinder 42 is provided, the detection component 40 may be provided on the upper side of the lifting assembly 30, that is, on the side facing the drive member 20 and the damping stabilizer 60, so that the rangefinder 42 can detect the distance between the measuring component and other components above along the extension direction of the first sling 31.

[0080] Specifically, the rangefinder 42 can be a laser rangefinder or similar structure, with its detection port facing upwards. When the bottom of the damping stabilizer 60 is directly or nearly directly aligned with the detection port of the rangefinder 42 in the detection assembly 40 along the extension direction of the first sling 31, the rangefinder 42 can detect the distance between the damping stabilizer 60 and the detection assembly 40. Furthermore, before the damping stabilizer 60 is lowered or when the damping stabilizer 60 and the rangefinder 42 are misaligned, the distance between the detection assembly 40 and the support beam 10, as well as the distance between the detection assembly 40 and the unlowered damping stabilizer 60, can be obtained.

[0081] Based on this, the specific position of the damping stabilizer 60, the descent dimension, and the distance between it and the first lifting device 32 can be obtained more accurately through the rangefinder 42, thereby controlling the descent position of the damping stabilizer 60 more accurately and flexibly, and further improving the possibility and efficiency of reducing the swing of the lifting device 32.

[0082] In some optional embodiments, a positioning part 621 protrudes from the lower side of the counterweight damper 62, and a base plate 611 is provided at the lower end of the mounting bracket 61. The base plate 611 is provided with a positioning hole 612 recessed along the thickness direction, and the positioning part 621 extends at least partially into the positioning hole 612.

[0083] Optionally, the weighted damper 62 in the damping stabilizer 60 can be suspended in the mounting frame 61, so that the upper end of the weighted damper 62 is connected to the mounting frame 61 by ball joint or snap-fit, and the lower end can be spaced apart from the mounting frame 61 to facilitate swinging.

[0084] Based on this, a positioning part 621 can be provided protruding from the lower end of the counterweight damper 62. The positioning part 621 can be provided to protrude along the axial direction of the counterweight damper 62, and its diameter can be smaller than the diameter of the counterweight damper 62, so as to save costs and make the corresponding positioning hole 612 easier to process.

[0085] The mounting bracket 61 may have a base plate 611 at the lower end, on which a positioning hole 612 recessed along its own thickness direction may be provided. The hole may be a through hole 613 or a recessed hole with a depth less than the thickness of the base plate 611. The positioning part 621 extends into the positioning hole 612 and can move in the positioning hole 612. After moving to the boundary, it may abut against the hole wall of the positioning hole 612, so as to limit the swing angle of the counterweight damper 62 through the cooperation of the positioning hole 612 and the positioning part 621.

[0086] The positioning part 621 and the positioning hole 612 can restrict the swing of the counterweight damper 62, reduce the possibility of the counterweight damper 62 swinging too much, causing the connection to loosen or be damaged by collision, and reduce the possibility of the effect of reducing the sway amplitude of the first sling 31 decreasing.

[0087] In some alternative embodiments, at least a portion of the edge of the positioning part 621 is spaced apart from the wall of the positioning hole 612, and the positioning part 621 is movable within the positioning hole 612.

[0088] In the embodiment where the counterweight damper 62 is limited by the cooperation of the positioning hole 612 and the positioning part 621, the cross-sectional area of ​​the positioning hole 612 can be greater than or equal to the cross-sectional area of ​​the positioning part 621, and the shapes of the two can be the same or similar, such as both being circular or polygonal, so that the counterweight damper 62 can have a certain degree of swing freedom in all directions.

[0089] During the operation of the hoisting equipment 100, the positioning part 621 can move in the positioning hole 612 as the weight damper 62 swings. The positioning hole 612 provides a certain amount of swing space, thereby giving the weight damper 62 a certain degree of swing freedom. Due to the influence of the structure of the damping stabilizer 60 and the swaying and tilting of the first sling 31, there is a significant difference in the swing stroke of the weight damper 62, the first sling 31, and the lifting device 32. At least for a certain period of time, the weight damper 62 may swing in the opposite direction to the swing direction of the lifting device 32 below, thereby further reducing the swing amplitude of the lifting device assembly 30.

[0090] By adjusting the relative size of the positioning part 621 and the positioning hole 612, the maximum tilt angle that the counterweight damper 62 can swing to can be adjusted accordingly, thereby changing the influence on the swing of the first sling 31.

[0091] In some optional embodiments, the damping stabilizer 60 further includes a plurality of elastic elements disposed between the weighted damper 62 and the mounting bracket 61. The plurality of elastic elements extend radially along the weighted damper 62 and are distributed circumferentially at intervals along the weighted damper 62. The elastic elements are connected to the weighted damper 62, or the elastic elements are connected to the mounting bracket 61.

[0092] Unlike the kinship device that limits the weight damper 62 through the positioning part 621 and the positioning hole 612, the damping stabilizer 60 can also limit the weight damper 62 by setting elastic elements between the mounting bracket 61 and the weight damper 62. These elastic elements can be selected to extend radially along the weight damper 62 and be able to stretch and contract in this direction so that the weight damper 62 can swing within a certain range. The swing amplitude of the weight damper 62 can be adjusted accordingly by adjusting the setting position, elastic modulus and size of the elastic elements.

[0093] When setting the elastic elements, multiple elastic elements can be arranged at intervals along the circumference of the counterweight damper 62 to limit the swing of the counterweight damper 62 in multiple directions. For example, these elastic elements can be spaced apart circumferentially, and the number of elastic elements can be 4, 8, etc., to ensure that the force applied to the counterweight damper 62 is uniform and reliable. The elastic elements can be springs, spring sheets, elastic pads, or elastic blocks, etc.

[0094] Optionally, these elastic elements can be interconnected with the counterweight damper 62 and / or the mounting bracket 61. In the compressed state, both ends of the elastic elements abut against the mounting bracket 61 and the counterweight damper 62, respectively. The elastic elements can be fixed by means of bonding, welding, snap-fitting, pressing, fastener connection, etc., as long as they can maintain a stable connection when subjected to impact and compression by the counterweight damper 62.

[0095] By providing elastic elements around the counterweight damper 62, the swing and tilt amplitude of the counterweight damper 62 in the circumferential direction can be limited, reducing the possibility of collision damage to the mounting bracket 61 and the counterweight damper 62.

[0096] In some alternative embodiments, the mounting bracket 61 further includes at least one through hole 613 extending in the direction through which the first sling 31 passes.

[0097] As previously stated, the first sling 31 passes through the mounting frame 61 so that the overall swing of the damping stabilizer 60 is synchronized with the swing of the first sling 31, while facilitating the application of force to the first sling 31 to reduce the swing amplitude.

[0098] Furthermore, the mounting bracket 61 may be provided with a through hole 613 extending along the extension direction of the first sling 31, and the first sling 31 may pass through the through hole 613. The diameter of the through hole 613 may be slightly larger than the diameter of the first sling 31, so as to facilitate the movement of the first sling 31 within it while defining the relative positional relationship between the two.

[0099] By providing through holes 613 on the mounting bracket 61, the relative position between the first sling 31 and the damping stabilizer 60 can be further defined. When the first sling 31 swings or tilts, the damping stabilizer 60 swings synchronously with the first sling 31 at the same height, thereby better reducing the swing amplitude of the lifting device 32 through its own commands. At the same time, the lifting and lowering of the damping stabilizer 60 can be made more stable, and the possibility of damage caused by the collision between the first sling 31 and the connecting bracket can be reduced.

[0100] In some optional embodiments, the first sling 31 includes multiple segments connected in sequence, each segment of the first sling 31 passing through the mounting frame 61. The mounting frame 61 includes multiple through holes 613, each segment of the first sling 31 corresponding to one through hole 613, and the multiple through holes 613 are centrally symmetrical about the central axis of the counterweight damper 62.

[0101] As previously described, the first sling 31 is used to connect the drive unit 20 and the lifting device 32. The lifting device assembly 30 may optionally include a fully extended first sling 31, one end of which may be fixed to the drive unit 20 or the support beam 10, and the other end may be connected to the drive unit 20 by means of winding around the torque output end of the drive unit 20, so that the drive unit can drive the lifting device 32 to rise and fall by changing the length of the first sling 31 exposed outside the drive unit 20.

[0102] Based on this, the first sling 31 can be divided into two or more sections with the position of the lifting device 32 as the dividing point. Each section of the first sling 31 can pass through the mounting frame 61 respectively. The number of through holes 613 can be set according to the number of sections of the first sling 31, that is, the number of times the first sling 31 passes through the position of the mounting frame 61. The through holes 613 are set in a one-to-one correspondence with each section of the first sling 31, and these through holes 613 can be evenly distributed on the damping stabilizer 60.

[0103] For example, the counterweight damper 62 has a large mass, and to facilitate swinging in various directions, the cross-section of the main body region of the counterweight damper 62 can be cylindrical or a regular polygon. In embodiments with multiple through holes 613, each through hole 613 can be centrally symmetrical about the central axis of the counterweight damper 62. This makes the damping stabilizer 60 more uniformly and stably stressed, facilitating the application of force to the first sling 31.

[0104] In some alternative embodiments, the detection component 40 also includes a level 43.

[0105] The detection component 40 in the hoisting equipment 100 is used at least to detect the angle between the first sling 31 in the lifting assembly 30 and the vertical direction, that is, to detect the tilt direction and tilt angle of the first sling 31. Optionally, the detection component 40 can also be used to detect the position of the damping stabilizer 60, etc. Therefore, in order to further improve the accuracy of the detection results, a level 43 can also be set in the detection component 40. The level 43 is used to correct the attitude of the detection component 40 itself, so that the installation positions of the detection elements such as the gyroscope 41 and the rangefinder 42 are horizontal.

[0106] Specifically, the correction can be performed when the first sling 31 is hanging naturally or when it is suspended with a counterweight and stationary, that is, when the first sling 31 is extended vertically as much as possible, so that the mounting surface of the gyroscope 41 and rangefinder 42 and other detection elements is extended horizontally, thereby improving the accuracy of the detection results of the aforementioned detection elements and thus improving the overall reliability of the hoisting equipment 100.

[0107] In some alternative embodiments, the hoisting device 100 also includes a speaker, which is communicatively connected to the controller 50, and is used to issue an alarm signal when the included angle exceeds a first threshold.

[0108] Optionally, the hoisting equipment 100 may also be equipped with a loudspeaker to issue an alarm signal when the trigger drive 20 stops or the trigger damping stabilizer 60 descends, so as to promptly alert the operators of the hoisting equipment 100 and other personnel on site.

[0109] The speaker can optionally be connected to the controller 50 for communication, and the controller 50 can control the speaker's sound output time, volume, and specific sound signal content. The speaker and the controller 50 can optionally be integrated into the same enclosure to facilitate connection between the two and save installation space.

[0110] Optionally, the speaker can be configured to broadcast different alarm signals when the included angle exceeds a first threshold or a second threshold, and can optionally simultaneously report relevant information such as the size of the included angle and the tilt direction, so as to facilitate further processing.

[0111] Optionally, in addition to the loudspeaker, the hoisting equipment 100 may also be equipped with other warning components, such as indicator lights and displays, to provide multi-faceted warnings to the operator, enabling the operator to be aware of the sling tilt in a timely manner and further improving the reliability of the hoisting equipment 100.

[0112] This application provides a hoisting device 100, including a support beam 10, a drive component 20, a lifting device assembly 30, a detection component 40, and a controller 50. The support beam 10 extends along a first direction X and is movable along a second direction Y, where the first direction X intersects with the second direction Y. The drive component 20 is movably connected to the support beam 10 and is movable along the first direction X. The lifting device assembly 30 includes a first sling 31 and a lifting device 32. The first sling 31 connects the lifting device 32 and the drive component 20, and the drive component 20 is used to drive the lifting device 32 to rise and fall via the first sling 31. The detection component 40 is disposed on the lifting device 32 and is used to detect the angle between the first sling 31 and the vertical direction. The controller 50 is communicatively connected to the drive component 20 and the detection component 40, respectively, and is used to acquire the angle and control the drive component 20 to stop when the angle exceeds a first threshold.

[0113] The hoisting equipment 100 also includes a damping stabilizer 60, which includes a mounting frame 61 and a counterweight damper 62. The counterweight damper 62 is installed inside the mounting frame 61, and the first sling 31 passes through the mounting frame 61. The drive unit 20 is also used to drive the damping stabilizer 60 to rise and fall, and the controller 50 is also used to control the damping stabilizer 60 to fall when the included angle exceeds a second threshold. The second threshold is less than or equal to the first threshold.
