Description

Technical Field

[0001] This utility model relates to the field of lifting machinery technology, and in particular to a new type of high-efficiency deceleration drive lifting device. Background Technology

[0002] In industrial production and logistics transportation, lifting equipment is widely used for vertical lifting of heavy objects. The key to lifting equipment lies in the drive system, which converts the high speed of the motor into the low speed and high torque of the drum.

[0003] Existing hoisting drive devices use traditional fixed-axis gearboxes for reduction transmission. The gear sets inside the traditional gearboxes are supported by sliding bearings or direct meshing. Under heavy-load hoisting conditions, the gear shaft is subjected to extremely large radial loads, which leads to a significant increase in frictional resistance between transmission components. After long-term operation, the gears and bearings wear out severely, which not only reduces the mechanical transmission efficiency but also causes equipment vibration and noise, seriously affecting the stability and safety of the hoisting process. Furthermore, the existing reduction structure lacks effective circumferential support for the large-diameter driven gear, causing the driven gear to wobble under force, further aggravating wear and energy loss. It is difficult to meet the modern industrial requirements for efficient, stable, and durable hoisting equipment.

[0004] Therefore, this utility model proposes a new type of high-efficiency deceleration drive lifting device to overcome the shortcomings of the existing technology. Utility Model Content

[0005] In view of the problems existing in the high-efficiency deceleration new type of drive lifting equipment, such as the large frictional resistance and easy wear of the transmission components under high load conditions, the lack of effective circumferential support for the driven gear leading to poor transmission stability, and the inability of the lifting end to flexibly adapt to different sizes of heavy objects, resulting in great limitations in use, this utility model aims to provide a high-efficiency deceleration new type of drive lifting equipment with an improved structure that can effectively solve the above problems.

The end of the suspension rope away from the drum is connected to the adjustable mechanism.

[0009] Preferably, the adjustable mechanism includes a pulley and a support plate. The end of the suspension rope away from the drum passes around the pulley. The bottom of the pulley is rotatably connected to the support plate. A sliding rod is fixedly connected to the inner wall of the support plate, and a clamp is slidably connected to the outer wall of the sliding rod.

The rotating lead screw drives the gripper to make linear reciprocating motion along the slide bar. This achieves the effect of flexibly adjusting the clamping width, adapting to various sizes of goods, and greatly improving the stability of the fixed heavy objects and the safety of operation.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] Example:

[0028] Please refer to Figures 1 to 5 This utility model provides a new type of high-efficiency deceleration drive lifting device, which aims to solve the problems in the prior art where lifting devices cannot achieve stable output of large torque while ensuring high speed input, and the end clamping mechanism cannot adapt to heavy objects of different sizes.

[0029] Please refer to Figure 1 and Figure 2 The high-efficiency deceleration new type of drive lifting equipment mainly consists of a power input component, a reduction transmission component, and an end effector component. It includes a motor 1, a reducer housing 2, a reduction mechanism 3, and an adjustable mechanism 4. The reduction mechanism 3 is located in the reducer housing 2 and connected to the motor 1 to realize power transmission and conversion. The adjustable mechanism 4 is connected to the reduction mechanism 3 to realize the lifting and clamping of heavy objects. The motor 1 serves as the main power source, and its output end is fixedly connected to a drive gear 301. The outer wall of the drive gear 301 meshes with the outer wall of the driven gear 302. The drive gear 301 drives the driven gear 302 to rotate, achieving first-stage deceleration. The diameter of the driven gear 302 is designed to be larger than the diameter of the drive gear 301. Furthermore, the number of teeth of the driven gear 302 is designed to be greater than the number of teeth of the driving gear 301. A steel ball 303 is rolledly connected to the outer wall of the driven gear 302. The outer side of the steel ball 303 is rolledly connected to the inner wall of the ring 304. A base 305 is fixedly connected to the outer wall of the ring 304. The bottom of the base 305 is fixedly connected to the reducer housing 2. The ring 304, the base 305 and the steel ball 303 cooperate to form a rotational support structure for the driven gear 302. In order to ensure the stability of the rolling of the steel ball 303 and limit the axial displacement of the driven gear 302, an annular groove is opened on the inner wall of the ring 304 and a corresponding groove is opened on the outer wall of the driven gear 302. The steel ball 303 is embedded between the annular groove and the corresponding groove.

[0030] Please refer to Figure 2 and Figure 3The driven gear 302 in the reduction mechanism 3 has three pin holes 306 on its front side. The three pin holes 306 are arranged in a circular array with the axis of the driven gear 302 as the reference. Each pin hole 306 is fixedly connected to a driving wheel 307. The driving wheel 307 rotates together with the driven gear 302 to form a revolution. At the same time, a fixed shaft 310 is fixedly connected to the outer wall of the motor 1. The front end of the fixed shaft 310 is rotatably connected to a driven wheel 308. The outer walls of the three driving wheels 307 are all connected to the driven wheels 308. The outer wall of the drive wheel 307 contacts the passive wheel 308, which is driven by the revolution of the drive wheel 307 to achieve two-stage reduction. The multi-stage gear transmission structure ensures the high efficiency of power transmission and a significant increase in output torque. The front side of the passive wheel 308 is fixedly connected to the spindle 309, which serves as the final power output shaft. The outer wall of the spindle 308 is fixedly connected to the drum 401, and the outer wall of the drum 401 is wound with the hoisting rope 402. The spindle 309 drives the drum 401 to rotate, thereby realizing the control of the hoisting rope 402.

[0031] As a preferred embodiment, in order to adapt to the lifting needs of heavy objects of different sizes and improve clamping stability, please refer to... Figure 4 and Figure 5 The high-efficiency deceleration new type of drive lifting equipment also includes an adjustable mechanism 4 connected to the end of the hoisting rope 402. The adjustable mechanism 4 includes a pulley 403 and a support plate 404. The end of the hoisting rope 402 away from the drum 401 passes around the pulley 403. The bottom of the pulley 403 is rotatably connected to the support plate 404. A sliding rod 405 is fixedly connected to the inner wall of the support plate 404. A gripper 408 is slidably connected to the outer wall of the sliding rod 405. The width of the load can be adaptively adjusted by the sliding of the gripper 408 along the sliding rod 405.

[0032] In another preferred embodiment, in order to achieve precise control and self-locking of the position of the gripper 408, a lead screw 406 is rotatably connected to the inner wall of the support plate 404. The rear end of the lead screw 406 is rotatably connected to the inner wall of the support plate 404, and the front end of the lead screw 406 passes through the support plate 404 and extends to the outside of the support plate 404. A rotating wheel 409 is fixedly connected to one end of the lead screw 406 located outside the support plate 404. The outer wall of the lead screw 406 is threadedly connected to the gripper 408. By rotating the rotating wheel 409, the lead screw 406 is driven to rotate, thereby driving the threaded gripper 408 to perform linear reciprocating motion along the slide bar 405.

[0033] As a further preferred embodiment, in order to improve the structural strength and provide auxiliary support for the lead screw 406 and slide bar 405, a fixing plate 407 is fixedly connected to the inner wall of the support plate 404. The outer wall of the fixing plate 407 is provided with a through groove. The outer walls of the lead screw 406 and the slide bar 405 both pass through the through groove of the fixing plate 407, thereby enhancing the rigidity of the overall structure while ensuring smooth movement.

[0034] In another preferred embodiment, in order to balance the force during the lifting process and improve the stability of the equipment operation, the drum 401 is divided into two parts along the axial direction, the number of pulleys 403 is set to two sets, the two sets of pulleys 403 correspond to the two parts of the drum 401 respectively, and the number of grippers 408 is set to two, the two grippers 408 are respectively set on both sides of the support plate 404, forming a symmetrical double-point lifting and bidirectional clamping structure.

[0035] Working principle:

[0036] When lifting operations are performed, motor 1 is started. The output shaft of motor 1 drives the drive gear 301 to rotate at high speed. The drive gear 301 drives the driven gear 302 with a larger outer diameter to rotate at a reduced speed through gear meshing. During this process, steel balls 303 roll between the driven gear 302 and the ring 304 to provide stable support and reduce frictional resistance. As the driven gear 302 rotates, the driving wheel 307, which is fixedly installed in the pin hole 306 of the driven gear 302, revolves around the driven wheel 308. The driving wheel 307 drives the driven wheel 308 at the center to rotate through contact friction or meshing on the outer wall, thereby achieving a two-stage speed reduction and torque increase effect. The driven wheel 308 drives the spindle 309 and the drum 401 to rotate synchronously, so that the lifting rope 402 wound on the drum 401 is wound up. The lifting rope 402 pulls the adjustable mechanism 4 below and the heavy object through the pulley 403 to achieve stable lifting.

[0037] When faced with heavy objects of different sizes that need to be clamped and fixed, the rotating wheel 409 located on the outside of the support plate 404 is manually rotated. The rotating wheel 409 drives the lead screw 406 passing through the fixed plate 407 to rotate. Since there is a threaded engagement between the lead screw 406 and the gripper 408, and the gripper 408 is restricted by the guide of the slide bar 405 and cannot follow the rotation of the lead screw 406, the rotational motion of the lead screw 406 is converted into the linear reciprocating motion of the gripper 408 along the length of the slide bar 405. By controlling the rotation direction of the rotating wheel 409, the grippers 408 on both sides are driven to move closer to each other to clamp the heavy object, or move further apart to release the heavy object, thereby preventing the heavy object from falling off during the lifting process.
