Description

Technical Field

[0001] This application relates to the field of winch technology, and in particular to multi-drum winches. Background Technology

[0002] In modern industry, multi-drum winches are widely used in mining, ports, construction, and other sectors as important material lifting, traction, and transportation equipment. Their working principle involves a drive unit that rotates multiple drums, winding and unwinding the wire rope to lift, lower, or move heavy objects horizontally. Because different working conditions require different drum diameters, rope capacity, and load-bearing capacities, and because the drums experience wear, fatigue damage, and corrosion over long-term use, frequent drum replacement is necessary. Therefore, the ease of drum disassembly is a crucial factor affecting the efficiency and maintenance costs of multi-drum winches.

[0003] In existing technology, the drum is usually mounted on the winch frame with both ends fixed. This means that maintenance and disassembly require operation of the fixed components at both ends, resulting in high maintenance frequency in complex environments. Appropriate wrenches should be used to loosen the fixing bolts at both ends, and then a crane or jack should be used to slowly lift the drum from the frame to separate it from the shaft.

[0004] Regarding the aforementioned technologies, the inventors believe that the method of fixing both ends of the rotating drum and requiring disassembly at both ends increases the complexity and workload of disassembly, reduces the efficiency of rotating drum replacement to an extremely low level, and increases equipment downtime. Utility Model Content

[0005] The purpose of this application is to provide a multi-drum winch to improve the problem that the method of fixing both ends of the drum and requiring disassembly at both ends increases the complexity and workload of disassembly.

[0006] This application provides a technical solution for a multi-drum winch, which adopts the following:

[0007] A multi-drum winch includes a base plate, a fixed plate fixedly mounted on the base plate, and a movable plate slidably mounted along the length of the base plate. A hydraulic cylinder is mounted on the movable plate away from the fixed plate, and the output end of the hydraulic cylinder is fixedly connected to the movable plate. A plurality of rotating drums are rotatably mounted between the fixed plate and the movable plate, and one end of each rotating drum is rotatably connected to the movable plate. A side plate is mounted on the base plate on the side of the fixed plate away from the movable plate. A drive motor is mounted on the outer wall of the side plate, and a transmission assembly is mounted on the output end of the drive motor. A connector is mounted on the side of the transmission assembly away from the side plate. The connector penetrates the fixed plate and is rotatably connected to the fixed plate. The end of each rotating drum away from the movable plate is inserted and fixedly connected to the connector.

[0008] By adopting the above technical solution, a movable plate that can slide along the length of the base plate is set and is driven by a hydraulic cylinder. When it is necessary to disassemble the rotating drum, the hydraulic cylinder is activated to move the movable plate away from the fixed plate. The rotating drum and the plug-in cylinder are plugged and fixed. The movable plate drives the rotating drum to release the fixed relationship with the plug-in cylinder. The operation is simple and quick. Compared with the traditional method that requires disassembly of both ends, only the fixed relationship between the rotating drum and the movable plate needs to be disassembled, which improves the disassembly efficiency.

[0009] Optionally, the insertion cylinder is provided with a synchronous gear, and the synchronous gear is fitted with a synchronous toothed belt to drive several rotating cylinders to rotate synchronously.

[0010] By adopting the above technical solution, a synchronous gear is set on the plug-in drum, and a synchronous toothed belt drives several rotating drums to rotate synchronously, so that several rotating drums can run at the same speed and direction. During lifting or traction operations, the synchronous movement of multiple wire ropes can be guaranteed, avoiding problems such as uneven force on the wire ropes and cargo tilting caused by inconsistent rotation speed of the rotating drums, thus improving the working stability and safety of the equipment.

[0011] Optionally, a rectangular insertion rod is provided at the end of the rotating drum away from the moving plate, and the insertion drum has an insertion slot adapted to the rectangular insertion rod.

[0012] By adopting the above technical solution, the rectangular structural design can effectively prevent relative rotation between the rotating drum and the insertion drum, ensuring that the power can be accurately transmitted from the insertion drum to the rotating drum, improving the efficiency and reliability of power transmission, and also facilitating the installation and disassembly of the rotating drum.

[0013] Optionally, the transmission assembly includes a turntable one and a turntable two. The turntable one has several insertion holes, and the turntable two has several insertion rods. The turntable one and the turntable two are connected and fitted together with the insertion holes and insertion rods in a one-to-one correspondence.

[0014] By adopting the above technical solution, the transmission assembly uses turntable one and turntable two, which are connected by a one-to-one plug-in connection between the plug holes and the plug rods. Installation and disassembly are simple; just insert or pull the plug rod into or out of the plug hole. Furthermore, when maintenance or replacement of the drive motor or transmission assembly is required, the connection can be easily disconnected, reducing maintenance time and costs.

[0015] Optionally, an elastic retaining ring is provided inside the socket.

[0016] By adopting the above technical solution, an elastic fastening ring is set in the insertion hole. The elastic fastening ring can fasten the insertion rod, reduce the possibility of the insertion rod loosening or falling out during rotation, improve the stability and reliability of the transmission component connection, and further improve the overall performance of the equipment.

[0017] Optionally, the base plate is provided with a sliding groove for the movable plate to slide, and a sliding rod that is slidably connected to the movable plate is provided in the sliding groove.

[0018] By adopting the above technical solution, the combination of the slide groove and the slide rod provides a stable guiding effect for the sliding of the moving plate, enabling the moving plate to slide smoothly along the predetermined direction under the drive of the hydraulic cylinder, reducing the deviation or shaking of the moving plate during the sliding process, and facilitating the disassembly and installation of the rotary drum.

[0019] Optionally, a limit plate is provided on the side of the base plate away from the oil cylinder.

[0020] By adopting the above technical solution, the limiting plate can limit the maximum sliding distance of the moving plate, preventing the moving plate from exceeding the reasonable range during the sliding process and causing damage to the equipment; at the same time, the limiting plate can also play a protective role, preventing the moving plate from sliding excessively due to unexpected situations.

[0021] Optionally, the limiting plate is provided with a fixing rod that can be inserted into the moving plate on the side near the moving plate, and the fixing rod is threadedly connected with a fixing nut that cooperates with the limiting plate to clamp and fix the moving plate.

[0022] By adopting the above technical solution, vibration and impact forces will be generated during the operation of the multi-drum winch. By connecting the fixed rod to the moving plate and using the fixed nut in conjunction with the limiting plate for clamping and fixing, the fixing stability of the moving plate can be improved, the possibility of it sliding due to vibration or external force can be reduced, and the stability of the entire winch structure can be improved.

[0023] In summary, this application includes at least the following beneficial technical effects of multi-drum winches:

[0024] 1. By setting a movable plate that can slide along the length of the base plate and is driven by a hydraulic cylinder, when it is necessary to disassemble the rotating drum, the hydraulic cylinder is activated to move the movable plate away from the fixed plate. The rotating drum and the plug-in tube are plugged and fixed. The movable plate drives the rotating drum to release the fixed relationship with the plug-in tube. The operation is simple and quick. Compared with the traditional method that requires disassembly of both ends, only the fixed relationship between the rotating drum and the movable plate needs to be disassembled, which improves the disassembly efficiency.

[0025] 2. The limit plate can limit the maximum sliding distance of the moving plate, preventing it from exceeding the reasonable range during sliding and causing damage to the equipment; at the same time, the limit plate can also play a protective role, preventing the moving plate from sliding excessively due to unexpected situations.

[0026] 3. During the operation of a multi-drum winch, vibration and impact forces are generated. By connecting the fixed rod to the moving plate and using the fixing nut in conjunction with the limiting plate for clamping and fixing, the stability of the moving plate can be improved, the possibility of it sliding due to vibration or external force can be reduced, and the stability of the entire winch structure can be improved.

The hydraulic cylinder 4 is fixedly connected to the base plate 1 by bolts, and the output end of the hydraulic cylinder 4 is fixedly connected to the movable plate 3 by welding. The base plate 1 has a sliding groove 41 for the movable plate 3 to slide. The sliding groove 41 is integrally formed on the base plate 1 by machining. A sliding rod 42 is mounted in the sliding groove 41 and slidably connected to the movable plate 3. The sliding rod 42 is fixedly mounted at both ends of the sliding groove 41 by bolts. The movable plate 3 is fitted onto the sliding rod 42 and can slide along the sliding rod 42, thereby ensuring the stability of the sliding of the movable plate 3. Two limiting plates 9 are welded to the side of the base plate 1 away from the oil cylinder 4 on the side of the moving plate 3. A fixing rod 91 that can be inserted into the moving plate 3 is provided on the side of the limiting plate 9 near the moving plate 3. The fixing rod 91 is connected to the limiting plate 9 by welding. The fixing rod 91 is threaded with a fixing nut 92 that cooperates with the limiting plate 9 to clamp and fix the moving plate 3. The fixing nut 92 is detachable. When the moving plate 3 moves to the appropriate position, the fixing rod 91 is inserted into the corresponding hole of the moving plate 3, the fixing rod 91 is installed and the fixing nut 92 is tightened to fix the position of the moving plate 3.

[0032] Reference Figure 1A plurality of rotating cylinders 5 are rotatably arranged between the fixed plate 2 and the movable plate 3. In this embodiment, there are two, but more are possible. The movable plate 3 is fixedly mounted with a fixed bearing seat 10 by bolts. One end of the rotating cylinder 5 is installed in the fixed bearing seat 10 by a bearing, thereby realizing the rotatable connection between the rotating cylinder 5 and the movable plate 3. A rectangular plug-in rod 51 is provided at the end of the rotating cylinder 5 away from the movable plate 3. The rectangular plug-in rod 51 and the rotating cylinder 5 are an integral structure.

[0033] Reference Figure 1 , Figure 2 A side plate 11 is welded to the base plate 1 on the side of the fixed plate 2 away from the moving plate 3. A drive motor 12 is bolted to the outer wall of the side plate 11. A transmission assembly 6 is provided at the output end of the drive motor 12. The transmission assembly 6 includes a first turntable 61 and a second turntable 62. The first turntable 61 is connected to the output shaft of the drive motor 12 by a key, and can rotate synchronously with the output shaft. It is also convenient for disassembly and installation. The first turntable 61 has a number of insertion holes 611. The number of insertion holes 611 is not fixed. In this embodiment, there are five insertion holes 611. It is formed on turntable 61 by machining; turntable 62 is provided with several insert rods 621, and the insert rods 621 and turntable 62 are an integral structure. Turntable 61 and turntable 62 are connected to the insert rods 621 one by one through the insertion holes 611; an elastic fastening ring 612 is provided in the insertion hole 611. The elastic fastening ring 612 is made of rubber material and is installed in the insertion hole 611 by interference fit to enhance the tightness of the connection between the insert rod 621 and the insertion hole 611 and prevent the insert rod 621 from loosening.

[0034] Reference Figure 1 , Figure 2 A plug-in cylinder 7 is welded to the side of the transmission assembly 6 away from the side plate 11 and the turntable 62. The plug-in cylinder 7 passes through the fixed plate 2 and is rotatably connected to the fixed plate 2 through a bearing. The plug-in cylinder 7 has a plug-in groove 71 adapted to the rectangular plug-in rod 51. The plug-in groove 71 is formed by machining on the plug-in cylinder 7. The rectangular plug-in rod 51 at the end of the rotating cylinder 5 away from the moving plate 3 is inserted into the plug-in groove 71 of the plug-in cylinder 7 to achieve plug-in fixation between the rotating cylinder 5 and the plug-in cylinder 7. When the drive motor 12 drives the plug-in cylinder 7 to rotate through the transmission assembly 6, it can synchronously drive the rotating cylinder 5 to rotate. When the output end of the hydraulic cylinder 4 pushes the moving plate 3 to slide away from the fixed plate 2 along the sliding groove 41 and sliding rod 42 on the bottom plate 1, the crane lifts the rotating cylinder 5 to keep the rotating cylinder 5 stable.

[0035] The implementation principle of this application embodiment is as follows:

[0036] In actual use, the disassembly process of the rotating drum 5 is as follows: First, stop the drive motor 12 and disconnect the power. Use a wrench to loosen the fixing nut 92, pull the fixing rod 91 out of the moving plate 3, and release the fixing state between the moving plate 3 and the limit plate 9. Start the hydraulic cylinder 4. The output end of the hydraulic cylinder 4 pushes the moving plate 3 to slide away from the fixed plate 2 along the sliding groove 41 and sliding rod 42 on the base plate 1. At the same time, the crane lifts the rotating drum 5 to keep it stable. Since one end of the rotating drum 5 is rotatably connected to the moving plate 3 through the fixed bearing seat 10, when the moving plate 3 slides to a certain position, the rectangular plug rod 51 of the rotating drum 5 away from the moving plate 3 comes out of the plug groove 71 of the plug tube 7. At this time, the fixed bearing seat 10 is disassembled to release the connection and fixation of the rotating drum 5, and the old rotating drum 5 is lifted out between the fixed plate 2 and the moving plate 3 using a crane. Compared with the traditional method of disassembling both ends, only the fixing relationship between the rotating drum 5 and the moving plate 3 needs to be disassembled, which improves the disassembly efficiency.
