Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, specifically a low-voltage electric lifting column mechanism. Background Technology

[0002] Electric rising bollards are widely used in urban security and traffic control scenarios. However, existing low-voltage electric rising bollard mechanisms suffer from poor transmission stability and susceptibility to issues with lifting accuracy. For example, the transmission belt is prone to slippage and tension is difficult to maintain, leading to bollard jerking and inaccurate positioning. Furthermore, when the lifting mechanism slides within the casing, an unreasonable limiting structure can cause wobbling, affecting equipment lifespan and performance, and failing to meet the demands for efficient and stable control of rising bollards. Utility Model Content

[0003] (a) Technical problems to be solved.

[0004] To address the shortcomings of existing technologies, this utility model provides a low-pressure electric lifting column mechanism. By setting up a transmission tension adjustment structure (including a tensioning wheel, an electric guide rail, and an electric slider), it solves the problems of transmission belt slippage and unstable tension. By utilizing a limiting component (the limiting slider and the limiting groove cooperate), it improves the sliding stability of the lifting mechanism. The optimized structural layout realizes component integration, solves problems such as inconvenient installation and maintenance, and ensures stable and precise lifting of the lifting column.

[0005] (ii) Technical solution.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-voltage electric lifting column mechanism, including a base plate, a bottom shell fixedly installed at the bottom end of the base plate for protecting internal components and regulating the installation space, a drive component provided at one end of the base plate for providing lifting power, and a lifting mechanism component provided at the other end of the base plate for performing lifting actions.

[0007] The lifting mechanism assembly includes a rectangular outer shell fixedly installed at one end of a base plate, providing sliding space for the lifting mechanism. The lifting mechanism, which is the core actuator for lifting, is slidably installed inside the rectangular outer shell. Limiting components are provided at both ends of the lifting mechanism to ensure stable sliding direction. A lifting connection component is provided at the center of the top of the lifting mechanism for connecting to an external lifting column. A threaded shaft is threadedly connected to the lifting mechanism, driving the lifting mechanism to rise and fall by rotation. A bearing for rotating the threaded shaft is installed at one end of the base plate to ensure stable rotation of the threaded shaft. A driven pulley is fixedly connected to the bottom end of the threaded shaft to transmit power.

[0008] A drive motor is fixedly installed at the top of the other end of the base plate as a power source. The drive shaft at the bottom of the drive motor is fixedly connected to a drive pulley for initial power transmission. An electric guide rail is fixedly installed at the middle of the bottom end of the base plate, which works with an electric slider to adjust the position of the tension wheel. An electric slider is slidably installed on the outside of the electric guide rail to drive the tension wheel to move. A tension wheel is rotatably installed on the outside of the electric slider to adjust the tension of the transmission belt. The drive pulley, driven pulley and tension wheel are fitted with the same transmission belt to achieve power transmission.

[0009] As a further improvement of this utility model: the driving pulley, driven pulley, tensioner, and transmission belt are all located inside the bottom shell, which protects against external interference and ensures stable transmission.

[0010] As a further improvement of this utility model, a limiting groove is provided at the middle of each of the front and rear ends of the rectangular shell to provide sliding guidance for the limiting slider.

[0011] As a further improvement of this utility model: the limiting component includes a limiting slider fixedly connected to the middle of the front and rear ends of the lifting mechanism, and the limiting slider is slidably connected in the limiting groove on its corresponding side, limiting the lifting mechanism to slide only along the height direction of the rectangular shell to prevent deviation.

[0012] As a further embodiment of this utility model: the lifting connection assembly includes a lifting column fixedly connected to the top of the lifting core, which is directly connected to an external lifting column. A top connecting seat is fixedly installed at the top of the lifting column to facilitate docking with other equipment. A receiving cavity is provided inside the lifting column to accommodate the threaded shaft and adapt to the rotation space of the threaded shaft.

[0013] As a further improvement of this utility model: a top cover is fixedly connected to the top of the rectangular outer shell to protect the lifting part of the lifting column. A sliding groove is provided between the center of the upper and lower side walls of the top cover for the sliding assembly of the lifting column to ensure the stable lifting of the lifting column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, by setting a transmission tension adjustment mechanism consisting of an electric guide rail, an electric slider and a tensioning wheel, the tension of the transmission belt can be dynamically adjusted in real time according to the tension state of the transmission belt, which effectively avoids problems such as transmission belt slippage and slack, ensures the stability and continuity of power transmission, and thus improves the smoothness and positioning accuracy of the lifting column lifting process.

[0016] 2. In this utility model, the limiting component, which cooperates with the limiting slider and the limiting groove, precisely constrains the sliding trajectory of the lifting mechanism within the rectangular shell, preventing swaying and deviation during the lifting process, thus enhancing the stability of the overall structure. At the same time, the integrated component layout design simplifies the installation and maintenance process and extends the service life of the equipment. Attached Figure Description

[0025] Please see Figures 1-4 In this embodiment of the utility model, a low-voltage electric lifting column mechanism includes a base plate 1, a bottom shell 4 fixedly installed at the bottom end of the base plate 1 for protecting internal components and regulating the installation space, a drive component 3 provided at one end of the base plate 1 to provide lifting power, and a lifting mechanism component 2 provided at the other end of the base plate 1 to perform lifting actions.

[0026] The lifting mechanism assembly 2 includes a rectangular shell 21 fixedly installed at one end of the base plate 1, providing sliding space for the lifting mechanism 27. The lifting mechanism 27 is slidably installed inside the rectangular shell 21 and is the core actuator for lifting. Limiting components are provided at both ends of the lifting mechanism 27 to ensure stable sliding direction. A lifting connection component is provided at the center of the top of the lifting mechanism 27 for connecting to the external lifting column 23. A threaded shaft 26 is threadedly connected inside the lifting mechanism 27, which drives the lifting mechanism 27 to lift by rotation. A bearing 33 is installed at one end of the base plate 1 for rotating the threaded shaft 26 to ensure stable rotation of the threaded shaft 26. A driven pulley 34 is fixedly connected to the bottom end of the threaded shaft 26 to transmit power.

[0027] A drive motor 31 is fixedly installed at the top of the other end of the base plate 1 as a power source. The drive shaft at the bottom of the drive motor 31 is fixedly connected to the drive pulley 32 for initial power transmission. An electric guide rail 35 is fixedly installed at the middle of the bottom end of the base plate 1. The position of the tension wheel 37 is adjusted in conjunction with the electric slider 36. The electric slider 36 is slidably installed on the outside of the electric guide rail 35, which drives the tension wheel 37 to move. The tension wheel 37 is rotatably installed on the outside of the electric slider 36 to adjust the tension of the transmission belt 38. The drive pulley 32, the driven pulley 34 and the tension wheel 37 are sleeved on the outside of the same transmission belt 38 to realize power transmission.

[0028] The driving pulley 32, driven pulley 34, tensioner 37, and transmission belt 38 are all located inside the bottom shell 4. The bottom shell 4 provides protection against external interference and ensures stable transmission.

[0029] A limiting groove 25 is provided at the middle of each of the front and rear ends of the rectangular shell 21 to provide sliding guidance for the limiting slider 28.

[0030] The limiting component includes a limiting slider 28 fixedly connected to the middle of the front and rear ends of the lifting mechanism 27. The limiting slider 28 is slidably connected in the limiting groove 25 on its corresponding side, limiting the lifting mechanism 27 to slide only along the height direction of the rectangular outer shell 21 to prevent deviation.

[0031] The lifting connection assembly includes a lifting column 23 fixedly connected to the top of the lifting core 27, which is directly connected to an external lifting column 23. A top connecting seat 24 is fixedly installed at the top of the lifting column 23 to facilitate docking with other equipment. The lifting column 23 has a receiving cavity for accommodating the threaded shaft 26, which is adapted to the rotation space of the threaded shaft 26.

[0032] The top of the rectangular outer shell 21 is fixedly connected to the top cover 22, which protects the lifting part of the lifting column 23. A sliding groove is provided between the center of the upper and lower side walls of the top cover 22 for the sliding assembly of the lifting column 23, so as to ensure the stable lifting of the lifting column 23.

[0033] The working principle of this utility model is as follows: the drive motor 31 starts, the drive shaft drives the active pulley 32 to rotate, the active pulley 32 transmits power to the driven pulley 34 through the transmission belt 38, the driven pulley 34 drives the threaded shaft 26 to rotate. Because the lifting mechanism 27 is threadedly connected to the threaded shaft 26 and is limited by the limiting component, that is, the cooperation between the limiting slider 28 and the limiting groove 25, it can only slide along the height direction of the rectangular shell 21. When the threaded shaft 26 rotates, the lifting mechanism 27 drives the lifting column 23 to rise and fall along the groove of the top cover 22. During operation, if the tension of the transmission belt 38 changes, the electric guide rail 35 drives the electric slider 36 to move the tensioning wheel 37 to adjust the tension in real time, ensuring stable transmission and realizing precise and stable lifting of the lifting column.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
