Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically a novel mechanical support lifting device. Background Technology

[0002] Lifts are key pieces of equipment widely used in automotive repair, maintenance, tire replacement, and industrial production. Their core function is to smoothly and safely lift heavy objects (especially cars) to a designated height using mechanical, hydraulic, or pneumatic power systems, providing workers with convenient operating space below. From common scissor lifts and pole lifts (including single-pole, double-pole, and four-pole lifts) to mobile and ground-mounted lifts, lifts not only significantly improve work efficiency and reduce manual labor intensity, but also ensure the safety of the operation process with multiple safety protection devices (such as mechanical locks, anti-fall valves, and overload protection).

[0003] The new mechanical support lift is an innovative lifting device that integrates traditional mechanical transmission with modern precision control technology. This device is usually equipped with intelligent servo motor drive and digital control system, which can realize precise height adjustment, multi-point synchronous control and real-time load monitoring. It is especially suitable for industrial assembly lines, heavy vehicle maintenance and high-precision operation scenarios with strict requirements for lifting stability.

[0004] However, existing mechanical support lifts, especially those with traditional fixed connections that rely on hydraulic or electrical systems, are prone to response lag, position drift, or control errors, affecting lifting accuracy and stability. Furthermore, the support cannot maintain a stable position under heavy loads, requiring additional braking devices, which increases complexity and potential failure points, reducing safety and reliability. They also occupy a large space, making them unsuitable for use in compact equipment or confined spaces. To address these issues, a novel mechanical support lift is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0032] Reference Figures 1-3 This utility model discloses a novel mechanical support lift, comprising a support rod 1, one end of which is fixedly connected to a base shell 4, and one end of the base shell 4 is provided with a top shell 5. The base shell 4 and top shell 5 can be connected and fixed to necessary components and structures. A limiting component includes a fixing block 14, which penetrates and is fixedly connected to the outer wall of the base shell 4 at the other end, and also penetrates and is fixedly connected to the top shell 5. The fixing block 14 can be used to connect and fix necessary components and structures. One end of a lead screw 13 is provided with... A connecting rod 2 is fixedly connected to the other end of the support rod 1. The connecting rod 2 can limit and fix the required structure and components. One end of the outer wall of the connecting rod 2 is connected to a bearing rod 3. One end of the bearing rod 3 is connected to a sliding rod 6. The outer ring of the sliding rod 6 is fitted with a first spring 7. One end of the sliding rod 6 is fixedly connected to a pressure block 8. By pressing with the pressure block 8, the sliding rod 6 slides on the bearing rod 3, thereby pressing the first spring 7, so that the sliding rod 6 slides into the connecting rod 2.

[0033] Reference Figure 1 and Figure 2A first bevel gear 9 is rotatably connected to the inner wall of the bottom shell 4. A retaining ring 10 is fixedly connected to one end of the first bevel gear 9. A second bevel gear 12 is rotatably connected to one end of the outer wall of the bottom shell 4, and the second bevel gear 12 is rotatably connected to the top shell 5. The second bevel gear 12 meshes with the first bevel gear 9. A limiting cylinder 11 is fixedly connected to one end of the retaining ring 10, and the limiting cylinder 11 is rotatably connected to the top shell 5. A nut pair 18 is fixedly connected to the inner wall of the limiting cylinder 11, and the nut pair 18 contacts the top shell 5. The inner wall of the nut pair 18 is threaded. The bottom shell 4 is connected to a lead screw 13. A limit assembly is provided at the other end of the outer wall of the bottom shell 4. The rotation of the second bevel gear 12 causes the first bevel gear 9 to rotate on the bottom shell 4, which in turn causes the fixed ring 10 to rotate on the bottom shell 4. This causes the limit cylinder 11 to drive the nut pair 18 to rotate on the top shell 5, thereby allowing the lead screw 13 to move between the top shell 5 and the bottom shell 4. This achieves pure mechanical transmission (bevel gear meshing + lead screw 13 and nut pair 18) without the risk of hydraulic leakage or electrical failure. The displacement control is precise, and there is no lag or drift during the lifting process, ensuring long-term support stability.

[0034] Reference Figure 1 and Figure 2 One end of the fixed ring 10 is rotatably connected to the limiting cylinder 11, and the limiting cylinder 11 is rotatably connected to the top shell 5. One end of the fixed block 14 is slidably connected to the transmission rod 15, and one end of the transmission rod 15 is fixedly connected to the limiting rod 17, and the limiting rod 17 is slidably connected to the fixed block 14. The limiting rod 17 is in contact with the limiting cylinder 11, and a second spring 16 is sleeved on the outer ring of the limiting rod 17. By rotating the limiting cylinder 11, the limiting cylinder 11 is made to contact the limiting rod 17, thereby allowing the limiting rod 17 to slide on the fixed block 14, thereby allowing the transmission rod 15 to slide and displace on the fixed block 14, thereby compressing the second spring 16. This allows it to withstand multiple compression and rebound cycles, resulting in a long fatigue life. Compared with electromagnetic or hydraulic self-locking devices, it has less wear, a lower failure rate, and reduces maintenance requirements.

[0035] Working principle: By rotating the second bevel gear 12 between the bottom shell 4 and the top shell 5, and then meshing with the first bevel gear 9, the first bevel gear 9 rotates on the bottom shell 4, thereby driving the fixed ring 10 to rotate. The fixed ring 10 then drives the limiting cylinder 11 to rotate, which in turn drives the nut assembly 18 to rotate. This drives the lead screw 13 and displaces the top connecting rod 2 a specified distance. Simultaneously, when the limiting cylinder 11 rotates, it contacts the limiting rod 17 through a groove on its outer wall, pressing against it and thus allowing the limiting rod to rotate. Position rod 17 slides on fixed block 14, thereby allowing transmission rod 15 to slide on fixed block 14, which in turn compresses second spring 16, allowing limiting cylinder 11 to rotate. Subsequently, when limiting cylinder 11 rotates in the opposite direction, the rebound of second spring 16 allows transmission rod 15 and limiting rod 17 to reset, allowing limiting rod 17 to slide into the groove, thereby limiting limiting cylinder 11 and achieving self-locking. When reset is required, simply pull transmission rod 15 to allow limiting rod 17 to slide out of the groove, thereby allowing lead screw 13 to reset.
