Description

Technical Field

[0001] The utility model relates to the technical field of lifting slings, and more specifically, to an intelligent coiled material sling. Background Art

[0002] Coil generally refers to materials that are rolled continuously and hollow in the middle. In the process of producing coils, the coils need to be hoisted to the designated location. For heavy coils, a crane and coil hoist are required to be used together for hoisting. The traditional coil hoist is a C-type hoist. When in use, the hook of the C-type hoist is inserted into the center hole of the coil for hoisting. This type of hoist has a simple structure and is easy to use. However, when hoisting heavy coils, long-term repeated hoisting can easily cause cracks or deformation at the bend of the hoist, posing a major safety hazard. It is also easy to cause the coil to slip, and its durability and hoisting capacity are poor.

[0003] There is also a gate-type coiled material lifting device in the prior art, which includes a crossbeam and two hooks arranged on the crossbeam that can move toward each other. When in use, the two hooks move toward each other and are inserted into the center hole of the coiled material from both sides for lifting. Although this gate-type coiled material lifting device is more stable and safe, it cannot meet the placement requirements such as angle adjustment during lifting, has less freedom of movement, and has poor operational flexibility. Utility Model Content

[0004] The utility model aims to provide an intelligent coiled material sling, which can solve the technical problems of low freedom of movement and poor operational flexibility of current coiled material slings.

[0005] The utility model provides the following technical solutions: an intelligent coiled material hanger, comprising a hanging beam, a rotating mechanism, a track beam and two clamps arranged in sequence from top to bottom, a movable pulley block for connecting with a crane hoisting mechanism is arranged at the upper end of the hanging beam, the rotating mechanism comprises a rotating reduction motor and a slewing bearing, the inner ring and the outer ring of the slewing bearing are respectively connected with the hanging beam and the track beam, the rotating reduction motor is installed on the hanging beam, a driving gear is arranged at the output end, a driven gear ring meshing with the driving gear is arranged on the outer side of the lower part of the slewing support, and the track beam is driven to rotate around the vertical axis by the rotating reduction motor; the two clamps are respectively installed at At both ends of the track beam, the clamp is an overall hook-type structure, including a clamp body and a hook body located at the lower end of the clamp body. A movable track and an opening and closing mechanism are arranged on the track beam. A roller cooperating with the movable guide of the movable track is arranged on the top of the clamp. The opening and closing mechanism includes an opening and closing reduction motor and a driving gear arranged at the output end of the opening and closing reduction motor. The opening and closing reduction motor is arranged in the middle position of the track beam. A rack is arranged at the upper end of the clamp. The teeth of the two racks face opposite directions and are respectively connected to the upper and lower sides of the driving gear. The hook bodies of the two clamps are arranged facing each other and are used to be driven by the opening and closing mechanism to insert into the center hole of the coil from both sides when in use.

[0006] Furthermore, a collision detection mechanism is arranged at the lower end of the clamp, and the collision detection mechanism includes a trigger link, a support spring and a photoelectric switch. The trigger link is in an inverted L shape and includes a long side and a short side that are perpendicular to each other. The upper position of the long side is rotatably connected to the clamp body, and the lower end extends obliquely downward toward the hook body. The short side is cantilevered along the upper end of the long side to the side away from the hook body. The support spring is arranged below the short side and supports the connection between the outer end of the short side and the clamp body. The photoelectric switch is arranged on the swing path above the short side and is used to detect whether the trigger link is swung by the touch of the coil.

[0007] Furthermore, a laser sensor is arranged at a position above the adjacent hook body at the lower end of the clamp, and the laser sensor is used to detect whether the clamp interferes with the coil.

[0008] Furthermore, a limiting wheel for limiting the movement of the rack is arranged on the track beam.

[0009] Furthermore, four movable pulley blocks are provided, and the four movable pulley blocks are respectively provided at four corners of the suspension beam.

[0010] Beneficial effect: The process of using the intelligent coil lifter to lift coils is as follows: the intelligent coil lifter is driven by the crane to move to the coil position, and the two clamps are synchronously opened to the maximum opening size under the driving action of the opening and closing mechanism, and then the lifter is dropped to the target height position. When the laser sensor detects the center hole of the coil, it means that the lifter has been lowered to the position where the hook body and the center hole of the coil are aligned and there is no interference between the hook body and the coil. The opening and closing mechanism drives the two clamps to close and insert into the center hole of the coil. After the clamps are closed in place, the crane lifts the lifter and the coil and transports them to the target position. The coil can be rotated by the rotating mechanism during the process. When the coil falls and is placed at the target position, the two clamps move down slightly relative to the coil until the laser sensor detects the center hole of the coil, indicating that there is no interference between the hook body and the coil, and the clamps are opened, the lifter is lifted, and the lifting is completed;

[0011] The working process of setting up the collision detection mechanism is as follows: when the opening and closing mechanism drives the two clamps to close and insert into the center hole of the coil, the end of the coil hits the trigger link, the lower end of the long side of the trigger link swings downward, and the upper end of the long side swings upward with the short side. After the photoelectric switch detects the short side, the opening and closing mechanism stops closing the clamps, ensuring that the clamps and the coil are inserted in place while preventing the coil and the clamp body from colliding and being damaged, which has a buffering and protective effect; based on the above process, the utility model has multi-angle freedom of lifting, rotating, and opening and closing of the clamps during the process of lifting the coil, and the operation is flexible and convenient, which can meet the requirements of multi-angle placement; intelligent means such as collision detection mechanisms and laser sensors are adopted to ensure the safety and stability of the transportation process, prevent damage to the coil during lifting, reduce material loss caused by lifting, reduce production costs, and have a high degree of automation.

DETAILED DESCRIPTION

[0016] The utility model is described in detail below in conjunction with the accompanying drawings.

[0017] Specific embodiment 1 of an intelligent coiled material hanger of the utility model:

[0018] like Figure 1 and Figure 3 As shown, it is mainly composed of a suspension beam 1, a rotating mechanism, a track beam 3 and a clamp 4 which are arranged in sequence from top to bottom. Four pulley blocks 8 are respectively arranged at the four corners of the upper end of the suspension beam 1. The pulley blocks 8 are connected to the hoisting mechanism of the crane through a wire rope mechanism to realize the lifting, movement and balance of the suspension beam 1. The rotating mechanism includes a rotary reduction motor 7 and a slewing bearing 2. The rotary reduction motor 7 is installed on the suspension beam 1. A driving gear 5 is arranged at the output end of the rotary reduction motor 7. The inner ring of the slewing bearing 2 is connected to the suspension beam 1, and the outer ring is connected to the track beam 3. A driven gear ring 6 is arranged on the outer side of the outer ring of the slewing bearing 2. Under the action of the rotary reduction motor 7, the meshing transmission of the driving gear 5 and the driven gear ring 6 realizes the 360-degree rotation of the track beam 3 around the vertical axis.

[0019] The two ends of the track beam 3 are respectively provided with clamps 4. The clamps 4 are in a barb-shaped structure as a whole, including a clamp body 41 extending vertically and a hook body 42 located at the lower end of the clamp body 41. The hook bodies 42 of the two clamps 4 are arranged opposite to each other in the horizontal direction. A moving track and an opening and closing mechanism are arranged on the track beam 3. The moving track extends in the horizontal direction. A roller is arranged on the top of the clamps 4. The clamps 4 are guided and moved along the moving track by the roller. The opening and closing mechanism includes an opening and closing reduction motor 9 and a driving gear 12 located at the output end of the opening and closing reduction motor 9. A rack 10 is arranged at the upper end of the clamps 4. The teeth of the two racks 10 are one facing downward and the other facing upward, respectively meshing with the upper side and the lower side of the driving gear 12. Therefore, when the opening and closing reduction motor 9 is driven, the driving gear 12 drives the two clamps 4 to open (move away) or close (approach) synchronously. When lifting, the hook bodies 42 of the two clamps 4 approach from both sides and insert into the center hole of the coil, and then lift. In order to maintain the stable operation of the opening and closing mechanism, in this embodiment, a limiting wheel for guiding and cooperating with the rack 10 is provided on the track beam 3 to limit the movement of the rack 10 along a predetermined route.

[0020] The utility model also includes a collision detection mechanism and a laser sensor 11, and the collision detection mechanism, the laser sensor 11, the rotation mechanism, and the opening and closing mechanism are all electrically connected to the controller. Figure 2 As shown, the collision detection mechanism is arranged at the lower end of the clamp, and the collision detection mechanism includes a trigger link 15, a support spring 13 and a photoelectric switch 14. The trigger link 15 is in an inverted L shape, including a long side and a short side perpendicular to each other. The long side of the trigger link 15 is rotatably connected to the clamp body 41 at the upper position, and the lower end of the long side extends obliquely downward toward the hook body 42. The long side of the trigger link 15, the clamp body 41 and the hook body 42 form a right triangle; the short side of the trigger link 15 is cantilevered along the upper end of the long side to the side away from the hook body 42. The support spring 13 is located below the short side, and the two ends support and connect the outer end of the short side and the clamp body 41 respectively. The photoelectric switch 14 is located above the short side and on the rotation path of the short side. The collision detection mechanism works as follows: When the hook bodies 42 of the two clamps 4 are inserted into the center hole of the coil, the end of the coil hits the lower end of the long side of the trigger link 15 when it is inserted into place, the lower end of the long side of the trigger link 15 swings downward, and the upper end swings upward, and the short side of the trigger link 15 swings upward to overcome the elastic force of the support spring 13. The photoelectric switch 14 detects the short side, that is, the trigger link 15 is detected to be swung by the coil, and the clamps are closed in place, and the controller controls the opening and closing mechanism to stop closing. By setting up the collision detection mechanism, the clamps automatically stop closing after moving into place, avoiding the clamps from continuing to approach and collide with the coil, causing damage to the coil.

[0021] The laser sensor 11 is arranged at the lower end of the clamp 41 and above the hook body 42. The function of the laser sensor 11 is to prevent the two clamps from interfering with the coil when opening or closing. The laser sensors 11 on both sides shoot at the object to be measured. When the coil is detected, it means that the clamp hook body is not aligned with the position of the middle hole of the coil, there is interference between the clamp hook body and the coil, and the clamp hook body position has not been lifted or lowered; when the middle hole of the coil is detected between the laser sensors 11, it means that the clamp hook body is aligned with the position of the middle hole of the coil, there is no interference between the clamp hook body and the coil, and the clamp hook body position has been lifted or lowered, and the controller can make the opening and closing mechanism drive the two clamps to move.

[0022] Based on the above structure, the process of lifting the coiled material of the utility model is described: the utility model is operated to the target coiled material position by a crane, and the opening and closing mechanism drives the two clamps to open synchronously to the maximum opening size, and then the sling is lowered to the target height position. When the laser sensor detects the center hole of the coiled material and there is no interference between the coiled material and the clamps, the opening and closing mechanism drives the two clamps to close, and the two clamp hooks are inserted into the center hole of the coiled material. After the photoelectric switch of the collision detection mechanism is triggered, the clamps are closed in place and stop closing; the crane lifts the sling and the coiled material for transportation, and realizes the angular rotation of the track beam and the coiled material through the rotating mechanism, and the lowered sling places the coiled material to the target position. When the laser sensor detects the center hole of the coiled material and there is no interference between the coiled material and the clamps, the opening and closing mechanism drives the two clamps to open, and the crane lifts the sling to complete this lifting operation.

[0023] To sum up the above process, the utility model not only has the advantages of durable structure, safety and stability, multiple degrees of freedom of movement and high flexibility, but also can realize interference detection and anti-collision shutdown functions, minimize the loss of coils during lifting, reduce production costs, and has the significant advantages of safety, reliability and high intelligence.

[0024] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
