Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, and in particular to a wire rope lifting mechanism. Background Technology

[0002] Currently, in inspections in mines, petrochemical plants, and power plants, inspection robots are gradually replacing manual inspections to improve operational efficiency, safety, and stability. These robots primarily rely on cameras mounted on a pan-tilt unit to obtain high-definition video of the inspection environment. To expand the pan-tilt unit's height adaptability, it often needs to have height adjustment capabilities. Existing screw jacks are generally quite tall and heavy, and multi-section jacks suffer from insufficient end-effector rigidity. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wire rope lifting mechanism.

[0004] The purpose of this utility model is achieved through the following technical solution: a wire rope lifting mechanism, including an upper plate, a bearing seat at the end of the upper plate, a bearing installed in the bearing seat, the bearing being mounted on a transmission shaft, the other end of the transmission shaft being connected to a drive mechanism, a rope winding wheel and a mounting plate being mounted on the transmission shaft, a fixed pulley being provided on the mounting plate, the fixed pulley being located directly below the rope winding wheel, and the steel rope wound on the rope winding wheel being connected to the lower plate through the fixed pulley.

[0005] Preferably, a mounting bracket is installed on the side of the mounting plate, a fixed pulley is installed on the mounting bracket, and a pressure plate is installed between the two ends of the mounting bracket, with the steel rope located between the pressure plate and the fixed pulley.

[0006] Preferably, the drive mechanism includes a motor, the power output end of the motor is connected to a reducer, and the output end of the reducer drives the transmission shaft to rotate via a coupling.

[0007] Preferably, the lower surface of the upper plate is provided with a slide rail a, which is located on both sides of the drive shaft. A slide block a is slidably mounted on the slide rail a, and a scissor mechanism is mounted below the slide block a. The upper surface of the lower plate is provided with a slide rail b, which is slidably mounted on the slide rail b. The other end of the scissor mechanism is mounted on the slide block b, and a fixed pulley is located inside the scissor mechanism.

[0008] Preferably, the winding wheel has a spiral groove.

[0009] This utility model has the following advantages: The drive mechanism drives the transmission shaft to rotate in different directions, thereby driving the rope wheel to rotate in different directions, which in turn winds and unwinds the steel rope, thereby raising or lowering the gimbal on the lower plate. At the same time, the steel rope rotates along the fixed pulley, thereby changing the direction of the steel rope, so that the steel rope can be better connected to the center of gravity of the lower gimbal, ensuring the stability of the gimbal during raising and lowering.

[0019] In this embodiment, as Figure 1 and Figure 2 As shown, a wire rope lifting mechanism includes an upper plate 3. A bearing seat 9 is provided at one end of the upper plate 3, and a bearing 10 is installed inside the bearing seat 9. The bearing 10 is mounted on a transmission shaft 14, the other end of which is connected to a drive mechanism. A rope winding wheel 8 and a mounting plate 15 are mounted on the transmission shaft 14. A fixed pulley 16 is provided on the mounting plate 15, located directly below the rope winding wheel 8. The steel rope 7 wound on the rope winding wheel 8 is connected to the lower plate 4 via the fixed pulley 16. The drive mechanism drives the transmission shaft 14 to rotate in different directions, thereby driving the rope winding wheel 8 to rotate in different directions, thus winding and unwinding the steel rope 7. This causes the gimbal on the lower plate 4 to rise or fall, while simultaneously causing the steel rope 7 to rotate along the fixed pulley 16, thereby changing the direction of the steel rope (the steel rope 7 is vertically downward), allowing the steel rope 7 to better connect to the center of gravity of the lower gimbal, ensuring the stability of the gimbal during lifting and lowering. In this embodiment, the upper plate 3 is mounted on an existing walking mechanism, thereby moving the existing gimbal on the lower plate 4. The drive mechanism is also existing and has not been modified here. Its specific structure includes a motor 1, the power output end of the motor 1 is connected to the reducer 2, and the output end of the reducer 2 drives the transmission shaft 14 to rotate via a coupling.

[0020] Furthermore, a mounting bracket 17 is mounted on the side of the mounting plate 15, a fixed pulley 16 is mounted on the mounting bracket 17, and a pressure plate 18 is installed between the two ends of the mounting bracket 17. The steel rope 7 is located between the pressure plate 18 and the fixed pulley 16. Specifically, the main function of the pressure plate 18 is to make the steel rope 7 fit against the surface of the fixed pulley 16, so that the direction of the steel rope 7 after passing through the fixed pulley 16 is vertically downward.

[0021] Furthermore, the lower surface of the upper plate 3 is provided with a slide rail a5, which is located on both sides of the drive shaft 14. A slide block a6 is slidably mounted on the slide rail a5, and a scissor mechanism 11 is mounted below the slide block a6. The upper surface of the lower plate 4 is provided with a slide rail b13, and a slide block b12 is slidably mounted on the slide rail b13. The other end of the scissor mechanism 11 is mounted on the slide block b12, and the fixed pulley 16 is located inside the scissor mechanism 11. Specifically, the output of motor 1 + reducer 2 drives the transmission shaft 14 through the coupling. The transmission shaft 14 drives the rope wheel 8 to rotate, thereby winding and unwinding the steel rope 7, which in turn drives the gimbal on the lower plate 4 to rise or fall. During the rising or falling process, the lower plate 4 will synchronously drive the cross rods on the scissor mechanism 11 to move relative to each other. At this time, the slide a6 and slide b12 cooperate to move along the slide rail a5 and slide rail b13. The scissor mechanism 11 here is an existing mechanism and has not been improved here, so it will not be described in detail. The main function of the scissor mechanism 11 is to enhance the horizontal rigidity.

[0022] In this embodiment, the winding wheel 8 has a spiral groove. Specifically, by having a spiral groove on the winding wheel 8, the steel rope 7 can be arranged along the groove during winding, thereby avoiding friction between the steel ropes 7 and improving the service life of the steel rope 7.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
