Description

Technical Field

[0001] This utility model relates to the field of traction elevator equipment technology, and in particular to a coaxial dual-engine power smooth traction elevator equipment. Background Technology

[0002] The coaxial dual-engine power smooth traction elevator is an elevator system that uses a dual-power system and has the following structure:

[0003] Main unit: The main unit is the core power component of the elevator. It adopts a dual-engine power system, which integrates two power sources together through a coaxial design to provide stable traction force;

[0004] Base: Used to fix the main unit and connected to the mounting base by bolts to ensure the stability of the main unit during operation;

[0005] Traction sheave: Connected to the elevator car via steel wire rope, it transmits power from the main unit to drive the elevator up and down.

[0006] The base is installed on the mounting base by connecting bolts and nuts. During the operation of the main unit, mechanical vibration will be generated. With long-term vibration, the connection between the nut and bolt will loosen, resulting in a decrease in the fixing effect between the base and the mounting base. This application proposes a solution to this problem by adding an anti-loosening mechanism to the outside of the base to prevent the nut from loosening, thereby ensuring the fixing effect between the base and the mounting base. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a coaxial dual-engine power smooth traction elevator device, which solves the technical problem that the main unit will generate mechanical vibration during operation, and with long-term vibration, the connection between the nut and bolt will loosen, resulting in a decrease in the fixing effect between the base and the installation foundation.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A coaxial dual-engine power smooth traction elevator device includes a main unit. A base is fixedly installed at the bottom of the main unit. Both ends of the base are provided with anti-loosening mechanisms to prevent nuts from loosening. Each anti-loosening mechanism includes a mounting cylinder, a spring, a connecting shaft, a pressure plate, and an anti-loosening block. The mounting cylinder is located outside the base. One end of the spring is fixedly connected to the inside of the mounting cylinder. The connecting shaft is slidably connected to the inside of the mounting cylinder. The other end of the spring is fixedly connected to the outside of the connecting shaft. The pressure plate is fixedly installed at the end of the connecting shaft away from the spring. The anti-loosening block is sleeved on the outside of the nut and is used to prevent the nut from rotating. Several pointed plates are fixedly installed on the side of each anti-loosening block near the pressure plate. Each pressure plate is provided with pointed plates on the side near the pointed plates.

[0010] Each pressure plate has a groove on the side near the first tip plate. The second tip plate is slidably connected inside the groove. A limiting shaft for restricting the vertical movement of the second tip plate is fixedly installed inside each groove. The second tip plate is slidably connected outside the limiting shaft. The groove is used to accommodate the second tip plate and restrict its vertical movement through the limiting shaft. At the same time, by adjusting the position of the second tip plate, it is ensured that the second tip plate can engage with the first tip plate.

[0011] Preferably, each base has a round hole on its upper surface, and the end of the mounting cylinder away from the pressure plate is engaged inside the round hole. Each base has a placement hole on its lower surface, and a mounting rod is rotatably connected inside each placement hole. Each mounting cylinder has a threaded hole on its exterior, and the mounting rod is threaded into the inside of the threaded hole, which is the disassembly and assembly structure of the mounting cylinder.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The base is connected to the bolts through its own holes, and then the nut is connected to the bolts. At this time, the pressure plate is pulled upward to move the pressure plate away from the nut. At this time, the spring is stretched. Then, the anti-loosening block is put on the outside of the nut. Then, the pressure plate is released. The pressure plate moves downward under the action of the spring until the second pointed plate and the first pointed plate mesh with each other. Therefore, when the nut tends to rotate due to rotation, the second pointed plate and the first pointed plate mesh with each other to prevent the rotation of the anti-loosening block, thereby preventing the rotation of the nut and ensuring the stability of the connection between the nut and the bolt, and thus ensuring the fixing effect between the base and the installation foundation.

[0014] Second, due to factors such as installation errors, component wear, or vibration, the second pointed plate and the first pointed plate may not be fully engaged. In this case, the position of the second pointed plate should be moved laterally to achieve engagement between the two, thereby ensuring the effectiveness of the anti-loosening mechanism.

[0023] This application provides a coaxial dual-engine power smooth traction elevator device, which effectively solves the technical problem that the main unit will generate mechanical vibration during operation, and the connection between the nut and bolt will loosen with long-term vibration, resulting in a decrease in the fixing effect between the base and the installation foundation. Example

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem that the host will generate mechanical vibration during operation, and with long-term vibration, the connection between the nut and bolt will loosen, resulting in a decrease in the fixing effect between the base and the mounting foundation. The overall idea is as follows:

[0025] To address the problems existing in the prior art, this utility model provides a coaxial dual-engine power smooth traction elevator device, including a main unit 1. A base 2 is fixedly installed at the bottom of the main unit 1. Both ends of the base 2 are provided with anti-loosening mechanisms to prevent the nuts from loosening. Each anti-loosening mechanism includes a mounting cylinder 3, a spring 4, a connecting shaft 5, a pressure plate 6, and an anti-loosening block 7. The mounting cylinder 3 is located outside the base 2. One end of the spring 4 is fixedly connected to the inside of the mounting cylinder 3. The connecting shaft 5 is slidably connected to the inside of the mounting cylinder 3. The other end of the spring 4 is fixedly connected to the outside of the connecting shaft 5. The pressure plate 6 is fixedly installed at the end of the connecting shaft 5 away from the spring 4. The anti-loosening block 7 is sleeved on the outside of the nut and is used to prevent the nut from rotating.

[0026] Each anti-loosening block 7 has several pointed plates 8 fixedly installed on the side near the pressure plate 6. Each pressure plate 6 has a groove 10 on the side near the pointed plate 8. Two pointed plates 9 are slidably connected inside each groove 10. A limiting shaft 11 for restricting the vertical movement of the pointed plate 9 is fixedly installed inside each groove 10. The pointed plate 9 is slidably connected to the outside of the limiting shaft 11.

[0027] Each base 2 has a round hole 12 on its upper surface. The end of the mounting cylinder 3 away from the pressure plate 6 is engaged with the inside of the round hole 12. Each base 2 has a placement hole 13 on its lower surface. The round hole 12 communicates with the inside of the placement hole 13. Each placement hole 13 is rotatably connected to the inside of the mounting rod 14. Each mounting cylinder 3 has a threaded hole 15 on its outside. The mounting rod 14 is threadedly connected to the inside of the threaded hole 15.

[0028] The anti-loosening mechanism is used to prevent the nut from loosening due to vibration or external force during the operation of the main unit 1, ensuring the stability of the connection;

[0029] The mounting sleeve 3 is used to accommodate the spring 4 and the connecting shaft 5, and is connected to the mounting rod 14 through the threaded hole 15 to fix the position of the anti-loosening mechanism.

[0030] Spring 4 provides elastic force, enabling pressure plate 6 to press down on anti-loosening block 7. Connecting shaft 5 is used to connect spring 4 and pressure plate 6, transmitting the elastic force of spring 4, so that pressure plate 6 can move up and down.

[0031] The anti-loosening block 7 is fitted onto the outside of the nut and prevents the nut from loosening by meshing with the pressure plate 6;

[0032] The engagement of the first pointed plate 8 and the second pointed plate 9 increases the friction between the anti-loosening block 7 and the pressure plate 6, preventing the nut from loosening.

[0033] Slide groove 10: Slide groove 10 is used to accommodate the second tip plate 9 and restrict its vertical movement by the limiting shaft 11. At the same time, by adjusting the position of the second tip plate 9, it is ensured that the second tip plate 9 can mesh with the first tip plate 8.

[0034] A round hole 12 is formed on the upper surface of the base 2 to fix the position of the anti-loosening mechanism. A placement hole 13 is used to install the mounting rod 14. The mounting rod 14 is connected to the threaded hole 15 of the mounting cylinder 3 through the placement hole 13 to fix the position of the mounting cylinder 3.

[0035] Working principle:

[0036] First, insert the mounting cylinder 3 into the round hole 12, and then connect the mounting rod 14 to the mounting cylinder 3 through the placement hole 13. At this time, connect the base 2 to the bolt through its own hole, and then connect the nut to the bolt. At this time, pull the pressure plate 6 upward to move the pressure plate 6 away from the nut. At this time, the spring 4 is stretched. At this time, the anti-loosening block 7 is sleeved on the outside of the nut. At this time, release the pressure plate 6. The pressure plate 6 moves downward under the action of the spring 4 until the second pointed plate 9 and the first pointed plate 8 mesh with each other. If the second pointed plate 9 and the first pointed plate 8 cannot mesh with each other, the position of the second pointed plate 9 can be moved laterally to achieve meshing. Therefore, when the nut rotates due to other factors, the meshing of the second pointed plate 9 and the first pointed plate 8 will prevent the rotation of the anti-loosening block 7, thereby preventing the rotation of the nut.

[0037] The second step is to move the pressure plate 6 upwards so that it is away from the anti-loosening block 7, and then disconnect the anti-loosening block 7 from the nut. At this time, the nut can be rotated.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
