Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a chain tilting machine with high stability. Background Technology

[0002] In mechanical welding and assembly processes, to ensure welding or assembly quality, improve welding or assembly efficiency, and enhance ease of welding or assembly, it is necessary to flip or reposition the components. For large mechanical parts, manual flipping or repositioning is not feasible; a flipping machine must be used.

[0003] The chain-type flipping machine uses a chain as the main transmission and flipping mechanism. The chain is driven by a power source such as a motor or hydraulic system to flip and rotate the workpiece. When the workpiece is lifted by the chain to a certain height, it is flipped by the rotation of the chain.

[0004] However, the distance between the support points at both ends of the existing chain-type turning machine is difficult to adjust during use. When the workpieces such as steel plates and steel materials that need to be turned are long, the two ends of the chain are close to the middle of the workpiece, while the two ends of the workpiece are far from the support points of the chain. This makes the stability of the workpiece on the chain poor. Especially when there is an angle of inclination during the operation of the machine, the workpiece is prone to tilting and then slipping off the chain under the action of gravity, which is quite dangerous. Utility Model Content

[0005] This invention provides a highly stable chain-type turning machine, aiming to solve the problem of poor chain stability in existing chain-type turning machines.

[0006] This utility model is implemented as follows: a highly stable chain-type turning machine includes a crossbeam mechanism, with two sprocket support mechanisms provided on the outer walls of both ends of the crossbeam mechanism. Two lifting lugs are fixedly connected to the top of the two sprocket support mechanisms. A groove is provided at the bottom of each of the two sprocket support mechanisms, and a turning mechanism for moving the chain is provided in each groove. A guide wheel is rotatably connected to the inner wall of the groove through a second rotating shaft. The guide wheel is positioned above the turning mechanism. A limit groove is provided around the outer wall of the guide wheel. A guide strip is provided around the outer ring of the chain. The guide strip matches the limit groove of the guide wheel and is embedded in the limit groove of the guide wheel to limit the chain.

[0007] Preferably, the flipping mechanism includes a first rotating shaft, a sprocket, and a drive motor. The first rotating shaft is rotatably connected to the inner wall of the groove, and the sprocket is fixedly connected to the outer wall of the first rotating shaft. A chain is sleeved around the sprocket. Multiple teeth are provided around the outer wall of the sprocket, and multiple moving grooves are provided around the inner ring of the chain. The multiple teeth of the sprocket mesh with the multiple moving grooves of the chain. Two drive motors are respectively fixedly connected to the opposite side walls of the two sprocket support mechanisms. The end of the first rotating shaft near the drive motor passes through the side wall of the sprocket support mechanism and is connected to the output end of the drive motor. A reducer is provided between the drive motor and the first rotating shaft, and the reducer is fixedly connected to the side wall of the sprocket support mechanism.

[0008] Preferably, the two drive motors are arranged symmetrically.

[0023] refer to Figures 1 to 5This highly stable chain-type tilting machine includes: a crossbeam mechanism 105, with two sprocket support mechanisms 101 mounted on the outer walls of both ends of the crossbeam mechanism 105. Two lifting lugs 106 are fixedly connected to the top of the two sprocket support mechanisms 101, suspending the crossbeam mechanism 105 and the two sprocket support mechanisms 101 below the crane wall via the two lifting lugs 106. Each sprocket support mechanism 101 has a groove at its bottom, and a tilting mechanism is installed in each groove. The flipping mechanism includes a first rotating shaft, a sprocket 104, and a drive motor 102. The first rotating shaft is rotatably connected to the inner wall of a groove, and the sprocket 104 is fixedly connected to the outer wall of the first rotating shaft. The sprocket 104 is used to sleeve a chain. Multiple teeth are provided around the outer wall of the sprocket 104, and multiple moving grooves 107 are provided around the inner ring of the chain. The multiple teeth of the sprocket 104 mesh with the multiple moving grooves 107 of the chain to prevent the chain from falling off the sprocket 104. The rotation of the sprocket 104 drives the chain to move. Two drive motors 102 are respectively fixedly connected to two sprocket supports. The sprocket support mechanism 101 has opposing side walls, and two drive motors 102 are symmetrically arranged. One end of the first rotating shaft near the drive motor 102 passes through the side wall of the sprocket support mechanism 101 and connects to the output end of the drive motor 102. A reducer is provided between the drive motor 102 and the first rotating shaft, and the reducer is fixedly connected to the side wall of the sprocket support mechanism 101. The drive motor 102 is used to drive the first rotating shaft to rotate, thereby driving the sprocket 104 to rotate. The reducer is used to reduce the speed and increase the torque. The drive motor 102 is existing technology and will not be described in detail in this utility model. A guide wheel 103 is rotatably connected to the inner wall of the groove through a second rotating shaft. The guide wheel 103 is located above the flipping mechanism, and a limit groove is formed around the outer wall of the guide wheel 103. A guide bar 108 is provided around the outer ring of the chain. The guide bar 108 matches the limit groove of the guide wheel 103. The guide bar 108 is embedded in the limit groove of the guide wheel 103 to limit the chain, prevent the chain from shaking during movement, and increase the stability during the workpiece flipping process. Anti-slip strips 109 are fixedly connected to both sides of the inner wall of the chain near the edge. The anti-slip strips 109 are used to increase the friction between the chain and the workpiece to be flipped, so as to prevent the workpiece from slipping during the flipping process and affecting the flipping efficiency. Two sprocket support mechanisms 101 are slidably connected to the crossbeam mechanism 105. The two sprocket support mechanisms 101 slide along the outer wall of the crossbeam mechanism 105 to adjust the distance between them, thereby adjusting the distance between the two chains to accommodate workpieces of different sizes.

[0024] Working Principle: The two sprocket support mechanisms 101 slide according to the workpiece size, adjusting the distance between them. The workpiece is then placed into the two chains. Two drive motors 102 are activated, driving two first rotating shafts. These shafts rotate the two sprockets 104. The multiple teeth of the sprockets 104 mesh with the multiple moving grooves 107 of the chains, causing the two chains to move. The chains gradually rotate the workpiece to the desired angle. The anti-slip strips 109 on the inner wall of the chains provide anti-slip protection. During the rotation, the guide strips 108 on the outer wall of the chains move within the limiting grooves of the guide wheels 103, causing the guide wheels 103 to rotate. The limiting grooves, through the guide strips 108, guide and limit the chain, preventing excessive shaking during movement and improving the stability of the workpiece rotation.

[0025] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that controls servo motors, contact sensors, processors, alarm modules, and drive modules. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding that are mature in the prior art. Furthermore, the machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.
