Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a trolley system for use in high-temperature environments of elevators. Background Technology

[0002] A trolley trolley is a mechanical device used in the accumulation chain conveyor system in a smart manufacturing plant. It consists of several parts, including drive equipment, power transmission equipment, and push equipment. In the entire conveyor system, it is used in combination with accumulation chain conveyors and friction drives to transport various production materials to the working position by pushing the lifting device.

[0003] The development trend of push cart machines is as follows:

[0004] Intelligentization: With the continuous development of artificial intelligence and Internet of Things technologies, cart pushers will become increasingly intelligent. Future cart pushers will have functions such as automatic identification, automatic planning, and automatic adjustment, enabling them to better adapt to different conveying needs.

[0005] High-speed operation: To improve conveying efficiency, the operating speed of cart pushers will continue to increase. High-speed cart pushers will be able to complete conveying tasks in a shorter time.

[0006] Multifunctionality: In addition to forward conveying, future trolley pushers will have more functions, such as forward and reverse pushing, lifting device turning, and power assistance in high-temperature environments. Multifunctional trolley pushers will provide a more comprehensive conveying solution for the system.

[0007] Energy conservation and environmental protection: With increasing environmental awareness, trolley machines will place greater emphasis on energy conservation and environmental protection. Future trolley machines will adopt more energy-efficient motors and control systems to reduce energy consumption; at the same time, they will also use more environmentally friendly materials and manufacturing processes to reduce environmental pollution.

[0008] In recent years, with the rapid development of China's logistics equipment industry, conveyor systems have become more complex and versatile. As a result, the application demand for cart pushers is constantly increasing, as they can fill gaps in applications where friction drives or accumulation chains cannot. Consequently, the demand for cart pushers in high-temperature environments is also growing. Since these environments can reach temperatures exceeding 220 degrees Celsius, maintenance in such conditions presents significantly greater difficulties and costs should equipment malfunction. Therefore, increasing investment in the research and development of high-temperature cart pushers and developing cart pushers capable of stable operation in high-temperature environments is urgently needed.

The power mechanism includes a drive motor, a central sprocket assembly, a transmission chain, and a top sprocket assembly. The drive motor is located outside the high-temperature chamber, the central sprocket assembly is located in the middle of the bracket, and the top sprocket assembly is located at the top of the bracket.

The wheel set and top sprocket set rotate. The trolley mechanism includes a trolley track, a trolley, and a transmission assembly. The trolley track is fixed to the lifting mechanism, and the trolley is slidably connected to the trolley track. The transmission assembly is rotatably connected to the lifting mechanism.

[0011] To facilitate the connection between the drive motor and the transmission chain for steering, the drive motor is connected to the transmission chain via a bottom transmission assembly.

[0012] Preferably, the middle sprocket assembly or the top sprocket assembly includes a mounting plate and a plurality of sprockets rotatably connected to the mounting plate, wherein the mounting plate has guide slots that allow the meshing gears of the transmission assembly to enter.

[0013] Because the drive chain is relatively long, a tensioning assembly is provided on the middle sprocket assembly to automatically adjust its tension and ensure the effectiveness of the transmission. The tensioning assembly includes a counterweight, a compression spring, a tension wheel, and a tension shaft. A lifting groove perpendicular to the horizontal plane is provided on the mounting plate. The tension wheel is located in the lifting groove and is connected to the drive chain. The counterweight is fixed to the tension wheel via the tension shaft.

[0027] like Figure 1-3 The trolley system shown is used in a high-temperature environment of an elevator. It includes a support 2 installed in a high-temperature chamber 1, a lifting mechanism 13 installed on the support 2, a trolley mechanism installed on the lifting mechanism 13, and a power mechanism connected to the trolley mechanism. The power mechanism includes a drive motor 3, a middle sprocket group 6, a transmission chain 5, and a top sprocket group 7. The drive motor 3 is installed outside the high-temperature chamber 1, and the other mechanisms are installed inside the high-temperature chamber 1. A ladder 8 is provided on one side of the support 2.

[0028] The central sprocket assembly 6 is located in the middle of the support 2, the top sprocket assembly 7 is located at the top of the support 2, and the lifting mechanism 13 is located on one side of the support 2. The lifting mechanism 13 can move up and down along the support 2 (the power motor of the lifting mechanism 13 is also located outside the high-temperature chamber 1). The drive motor 3 is connected to the bottom end of the transmission chain 5 through the bottom transmission assembly 4. The transmission chain 5 is connected to the central sprocket assembly 6 and the top sprocket assembly 7 respectively. The transmission chain 5 is perpendicular to the horizontal plane and meshes with the sprockets on the central sprocket assembly 6 and the top sprocket assembly 7. The trolley mechanism includes a trolley track 10, a trolley 9, and a transmission assembly 14. The trolley track 10 is fixed to the lifting mechanism. On the 13, the trolley 9 is slidably connected to the trolley track 15. There can be one or more trolleys 9. The transmission component 14 is rotatably connected to the lifting mechanism 13. One end of the transmission component 14 is connected to the trolley 9, and the other end of the transmission component 14 has a meshing gear that can mesh with the middle sprocket group 6 and the top sprocket group 7. The drive motor 3 can drive the middle sprocket group 6 and the top sprocket group 7 to rotate through the transmission chain 5. The middle sprocket group 6 and the top sprocket group 7 can drive the transmission component 14 to rotate through the meshing gear. The transmission component 14 can drive the trolley 9 to slide along the trolley track 10. The trolley 9 can push the lifting device 11 and the goods 12 on the stacking chain track to move forward.

[0029] Specifically, in combination Figure 4 , Figure 5As shown, the middle sprocket assembly 6 is located in the middle of the transmission chain 5, and the top sprocket assembly 7 is located at the top of the transmission chain 5. Taking the middle sprocket assembly 6 as an example, it includes a mounting plate 601 and several sprockets 602 rotatably connected to the mounting plate 601. Each sprocket 602 meshes with the transmission chain 5. The mounting plate 601 has a U-shaped guide slot 608 that allows the meshing gears of the transmission assembly to enter. The guide slot 608 opens upwards. In addition, the middle sprocket assembly 6 is provided with a tensioning assembly that can adjust the tension of the transmission chain 5. The tensioning assembly includes... The system includes a counterweight 607, a compression spring 606, a tension wheel 604, and a tension shaft 605. The mounting plate 601 has a lifting groove 603 perpendicular to the horizontal plane. The tension wheel 604 is disposed in the lifting groove 603 and meshes with the transmission chain 5. The counterweight 607 is fixed to the bottom end of the tension wheel 604 through the tension shaft 606. The tension shaft 606 is elastically connected to the mounting plate 601 through the compression spring 606. The counterweight 607 can generate a downward pulling force on the tension wheel 604, thereby tensioning the transmission chain 5.

[0030] The tensioning assembly is used to tension the drive chain 5 when it is not engaged, which can solve the problem of continuous tension during long strokes. Based on the weight of the material being pushed, the magnitude of the thrust is calculated, and the weight of the counterweight 607 is scientifically calculated for tensioning the drive chain 5 during long strokes, ensuring that the tension is moderate. It prevents the chain from being under high load for a long time, nor is it too loose, to prevent the drive chain 5 from shaking and dislodging from the sprocket assembly. Tensioning is achieved by setting a high-temperature resistant compression spring 606, which increases the meshing force when the drive chain 5 is engaged. The installation space of the compression spring 606 is designed to be adjustable. By adjusting the compression length of the compression spring 606, the meshing force after engagement can be controlled, ensuring that it is neither too loose, causing the chain to slip, nor too tight, increasing frictional resistance.

[0031] It should be noted that the top sprocket group 7 and the middle sprocket group 6 are arranged opposite each other, have basically the same structure, the guide slots open downwards, and no tensioning components are provided.

[0032] Specifically, in combination Figure 6 , Figure 7As shown, the transmission assembly includes a transmission shaft 1401, a bearing housing 1402, and an end sprocket assembly 1405. The bearing housing 1402 is fixed to the lifting mechanism. The transmission shaft 1401 is rotatably connected to the bearing housing 1402. One end of the transmission shaft 1401 is connected to the trolley 9 through the end sprocket assembly 1405. The other end of the transmission shaft 1401 is provided with a meshing gear 1403, which can mesh with one of the sprockets on the top sprocket assembly 7 or the middle sprocket assembly 6. In addition, the other end of the transmission shaft 1401 is fixed with a guide wheel 1404, which is sleeved on the meshing gear 1403. There is a gap between the guide wheel 1404 and the two sides of the meshing gear 1403, so that the guide wheel 1404 can facilitate the meshing gear 1403 to mesh with the sprockets on the top sprocket assembly 7 or the middle sprocket assembly 6.

[0033] When using, combine Figure 1-7 As shown, when a low-position trolley is required, the motor drives the lifting mechanism 13 to descend along the support 2. The lifting mechanism 13 drives the entire trolley mechanism to descend. Finally, the meshing gear 1403 on the drive shaft 1401 of the trolley mechanism meshes with the sprocket on the middle sprocket assembly 6. At this time, the drive motor 3 can drive the middle sprocket assembly 6 to rotate through the transmission chain 5. The middle sprocket assembly 6 then drives the drive shaft 1401 to rotate through the meshing gear 1403. The drive shaft 1401 drives the trolley 9 to slide along the trolley track 10. The trolley 9 can push the lifting device 1 on the accumulation chain track. 1. The cargo 12 moves forward; similarly, when a high-level trolley is required, the lifting mechanism 13 drives the entire trolley mechanism to rise, and the meshing gear 1403 on the drive shaft 1401 of the trolley mechanism meshes with the sprocket on the top sprocket assembly 7. The drive motor 3 can drive the top sprocket assembly 7 to rotate through the drive chain 5, and the top sprocket assembly 7 drives the drive shaft 1401 to rotate through the meshing gear 1403. The drive shaft 1401 drives the trolley 9 to slide along the trolley track 10, and the trolley 9 can push the lifting device 11 and cargo 12 on the stacking chain track to move forward.
