Abstract
Description
Technical Field
[0001] This utility model relates to the field of lens operation technology, and in particular to a heavy-duty coated lens forklift. Background Technology
[0002] In the production of optical lenses, especially large lenses (such as astronomical telescope lenses and large camera lens lenses), their size and weight are considerable. For example, the main mirrors of some astronomical telescopes can reach several meters in diameter and weigh in tons. Traditional manual handling and simple mechanical fixtures are insufficient to meet the requirements of high-precision processing and assembly. For the manufacturing of large lenses, a series of processes, from blank processing to grinding and polishing, require the lenses to be precisely placed on different processing equipment. Moreover, during transportation, it is necessary to avoid damage to the lenses from vibration, scratches, etc., which requires a specialized lifting and moving device to ensure the safety and processing accuracy of the lenses.
[0003] However, existing methods for lifting and operating large lenses can only adjust the approximate position and height of the lens. After lifting it to the designated height, they cannot make fine and precise adjustments to the lens's position, which affects the operation of the lens. Utility Model Content
[0004] To solve the above problems, this utility model provides a heavy-duty coated forklift, the specific technical solution of which is as follows:
[0005] A heavy-duty coated sheet forklift includes a rotating frame and a rotating moving structure. The rotating frame is mounted on the rotating moving structure, and the rotating moving structure can drive the position of the rotating frame to move horizontally. The rotating frame is provided with a vertical lifting structure, a lifting adjustment structure, and a lifting frame. The vertical lifting structure is mounted on the rotating frame, the lifting adjustment structure is mounted on the vertical lifting structure, and the lifting frame is located on the lifting adjustment structure.
[0006] Furthermore, the operating and moving structure includes a mounting box, a moving motor, a reducer, a rotating shaft, a rotating gear, a rotating rack, and two slide rails. The two slide rails are symmetrically arranged. Several equally spaced pulleys are provided at both ends of the bottom of the operating frame. The pulleys slide on the slide rails. The mounting box is located at the rear of the operating frame. The moving motor and the reducer are both located on the mounting box. The reducer is connected to the moving motor. The top of the rotating shaft is connected to the reducer. A bearing seat for rotating the rotating shaft is provided at the bottom of the mounting box. The rotating gear is located at the bottom of the rotating shaft. The rotating rack is horizontally arranged on one of the slide rails and meshes with the rotating gear.
[0007] Furthermore, the operating frame is equipped with two symmetrically arranged position sensors, which are electrically connected to the moving motor.
[0008] Furthermore, the vertical lifting structure includes a lifting cylinder, a lifting frame, and two outer slide rails. The lifting cylinder is vertically mounted on the operating frame, and the two outer slide rails are symmetrically arranged on the inner sidewalls of the operating frame. Each end of the lifting frame has three equally spaced slide blocks on its two end sidewalls. The two ends of the lifting frame are slidably connected to two slide rails through the three slide blocks. The telescopic end of the lifting cylinder is connected to the inner top of the lifting frame.
[0009] Furthermore, the lifting and adjusting structure includes a winch, an adjusting support, a mounting block, two adjusting wire ropes, and two inner slides. The two inner slides are symmetrically arranged on the inner wall of the lifting frame. Each inner slide has a sliding block seat. The winch is located inside the mounting box. The mounting block is horizontally arranged on the telescopic end of the lifting cylinder and located below the top of the lifting frame. Both ends of the mounting block are respectively provided with rotatably connected rope wheels. The adjusting support is horizontally connected to the two sliding block seats. One end of the adjusting wire rope is connected to the adjusting support, and the adjusting wire rope passes through the rope wheel and connects to the winch.
[0010] Furthermore, the lifting frame includes a rotating shaft seat, which is located at the end of the adjusting support. The rotating shaft seat is provided with a rotating bearing, and the rotating bearing is provided with a horizontally arranged lifting bracket. The lifting bracket is provided with four rectangularly distributed limiting blocks.
[0011] Beneficial Effects: In this invention, the winch drives the adjusting wire rope to rotate and wind it up. This rotation of the wire rope on the corresponding pulley causes the adjusting support to move upwards via two slider seats on two outer slide rails. This allows for precise adjustment of the lens position on the lifting frame, enabling the lens to be accurately moved to the required height for processing. Precise height adjustment ensures accurate distance and angle between the lens's processing surface and processing tools (such as grinding discs and polishing heads). Furthermore, precise height adjustment helps adjust the lens's position in the optical path, ensuring its optical axis is precisely aligned with other components of the optical system (such as light sources and detectors). Taking an astronomical telescope lens as an example, precise height adjustment ensures accurate positioning of the lens within the telescope's optical system, enabling the telescope to obtain clear and accurate celestial images and avoiding optical aberrations caused by lens positional deviations.

[0020] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
[0021] Reference Figures 1 to 7 This embodiment proposes a design for a heavy-duty coated sheet forklift, including a rotating frame 1 and a rotating moving structure 2. The rotating frame 1 is mounted on the rotating moving structure 2, and the rotating moving structure 2 can drive the position of the rotating frame 1 to move horizontally. The rotating frame 1 is provided with a vertical lifting structure 3, a lifting adjustment structure 4, and a lifting frame 5. The vertical lifting structure 3 is mounted on the rotating frame 1, the lifting adjustment structure 4 is mounted on the vertical lifting structure 3, and the lifting frame 5 is located on the lifting adjustment structure 4.
[0022] After the lens is placed horizontally on the support frame 5, the moving structure 2 can drive the lens to move horizontally, while the vertical support structure 3 can carry out a preliminary and approximate lifting and adjustment of the lens position. Then, the lifting and adjustment structure 4 can carry out a precise and detailed adjustment of the position of the support frame 5.
[0023] Preferably, the operating and moving structure 2 includes a mounting box 21, a moving motor 22, a reducer 23, a rotating shaft 24, a rotating gear 25, a rotating rack 26, and two slide rails 27. The two slide rails 27 are symmetrically arranged. The bottom ends of the operating frame 1 are respectively provided with a plurality of equally spaced pulleys 11. The pulleys 11 slide on the slide rails 27. The mounting box 21 is located at the rear of the operating frame 1. The moving motor 22 and the reducer 23 are both located on the mounting box 21. The reducer 23 is connected to the moving motor 22. The top of the rotating shaft 24 is connected to the reducer 23. The bottom of the mounting box 21 is provided with a bearing seat 28 for the rotating shaft 24 to rotate. The rotating gear 25 is located at the bottom of the rotating shaft 24. The rotating rack 26 is horizontally arranged on one of the slide rails 27 and meshes with the rotating gear 25.
[0024] When the lens is moved horizontally, the moving motor 22 drives the reducer 23 to work. The reducer 23 adjusts the speed transmitted from the moving motor 22, thereby driving the rotating shaft 24 to rotate on the bearing seat 28. This drives the rotating gear 25 to rotate on the rotating rack 26, thereby driving the rotating frame 1 to move horizontally on two slide rails 27 through several symmetrically arranged pulleys 11. This allows the rotating frame 1 to move horizontally, thus achieving the horizontal movement of the lens.
[0025] Preferably, the operating frame 1 is equipped with two symmetrically arranged position sensors 12, which are electrically connected to the moving motor 22. The position sensors 12 are Positek P101 type position sensors.
[0026] Two position sensors 12 can adjust the position of the rotating frame 1. After the rotating frame 1 moves to the end position of the slide rail 27, the position signal can be transmitted to the existing controller through the sensing of the position sensors 12. The controller transmits the signal to the moving motor 22, thereby controlling the moving motor 22 to stop rotating, thus achieving precise control when adjusting the lens in a horizontal position.
[0027] Preferably, the vertical lifting structure 3 includes a lifting cylinder 31, a lifting frame 32, and two outer slide rails 33. The lifting cylinder 31 is vertically mounted on the operating frame 1, and the two outer slide rails 33 are symmetrically mounted on the inner sidewalls of the operating frame 1. Each end of the lifting frame 32 has three equally spaced slide blocks 34. The two ends of the lifting frame 32 are slidably connected to two slide rails 27 through the three slide blocks 34. The telescopic end of the lifting cylinder 31 is connected to the inner top of the lifting frame 32.
[0028] When the lens is initially lifted, the extension end of the lifting cylinder 31 moves, which can drive the lifting frame 32 to move upward on the two inner slides 45 through the three corresponding slides 34 on both sides. This can drive the position of the lifting frame 32 to be adjusted upward, thereby lifting the lens on the lifting frame 5 to a specific height for preliminary adjustment, and lifting the lens to the initial height position.
[0029] Preferably, the lifting adjustment structure 4 includes a winch 41, an adjustment support 42, a mounting block 43, two adjustment wire ropes 44, and two inner slide rails 45. The two inner slide rails 45 are symmetrically arranged on the inner wall of the lifting frame 32. The inner slide rails 45 are provided with sliding block seats 47. The winch 41 is located inside the mounting box 21. The mounting block 43 is horizontally arranged on the telescopic end of the lifting cylinder 31 and located below the top of the lifting frame 32. The two ends of the mounting block 43 are respectively provided with rotatably connected rope wheels 46. The adjustment support 42 is horizontally connected to the two slide seats 47. One end of the adjustment wire rope 44 is connected to the adjustment support 42. The adjustment wire rope 44 passes through the rope wheel 46 and is connected to the winch 41.
[0030] The winch 41 drives the adjusting wire rope 44 to rotate and wind it up. This causes the wire rope to rotate on the corresponding pulley 46, which in turn drives the adjusting support 42 to move upwards on the two outer slide rails 33 via the two slider seats 47. This allows for precise adjustment of the lens position on the lifting frame 5, enabling the lens to be precisely moved to the required height for processing during the lifting process. During subsequent processing, the lens position can be adjusted according to the processing needs. Precisely adjusting the lifting height ensures that the processing surface of the lens maintains an accurate distance and angular relationship with the processing tools (such as grinding discs and polishing heads). Precisely adjusting the lifting height also helps to adjust the lens's position in the optical path, ensuring that its optical axis is precisely aligned with other components of the optical system (such as light sources and detectors). Taking an astronomical telescope lens as an example, precise height adjustment ensures the accurate position of the lens in the telescope's optical system, enabling the telescope to obtain clear and accurate celestial images and avoiding optical aberrations caused by lens position deviations.
[0031] Preferably, the lifting frame 5 includes a rotating shaft seat 51, which is located at the end of the adjusting support 42. The rotating shaft seat 51 is provided with a rotating bearing 52, and the rotating bearing 52 is provided with a horizontally arranged lifting bracket 53. The lifting bracket 53 is provided with four rectangularly distributed limiting blocks 54.
[0032] During operation, the lens is placed horizontally on the support bracket 53. The four limiting blocks 54 on the support bracket 53 can limit and fix the position of the lens to prevent the lens from shaking during the transfer and lifting process, which would affect the safety of the lens operation. The support bracket 53 can rotate on the rotating shaft seat 51 through the rotating bearing 52.
[0033] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
