Description

Technical Field

[0001] This invention relates to the field of hoisting and traction technology, specifically to a traction device for machining electromechanical equipment. Background Technology

[0002] Lifting refers to the general term for the installation and positioning of equipment using cranes or hoisting mechanisms. It's a specific term used for equipment positioning and generally requires lifting equipment (or lifting ropes). Towing typically refers to lifting an object and adjusting its height. When processing electromechanical equipment, especially large equipment, lifting and traction equipment is often used to lift and assemble large components. Currently, clamping devices are typically used to hold the workpiece, and then steel ropes are wound up to lift the workpiece. The workpiece is then moved to the required assembly position through the cooperation of the steel ropes and clamping devices.

[0003] However, the steel ropes of the hoisting equipment currently in use tend to sway when transferring workpieces, which makes the hoisted workpieces unstable and inconvenient to move to the designated location for assembly. Furthermore, due to the large size of the workpieces, there are significant safety hazards when they sway. Summary of the Invention

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a traction device for processing electromechanical equipment, comprising a traction top seat, a traction device fixedly connected to the bottom of the traction top seat, a hoisting base fixedly connected to the bottom of the traction device, and a positioning device fixedly connected to the top of the hoisting base;

[0005] The traction device includes:

[0006] The take-up roller has a circular cylindrical structure and a traction bracket disposed outside the take-up roller. Both ends of the take-up roller pass through the traction bracket and are rotatably connected to the traction bracket. A traction motor is fixedly connected to one side of the traction bracket, and the drive shaft of the traction motor is fixedly connected to the end of the take-up roller.

[0007] A connecting crossbar with a flat structure and arc-shaped racks at both ends are provided. The top of the arc-shaped racks is fixedly connected to the bottom of the connecting crossbar. A telescopic push rod is fixedly connected to the top of the connecting crossbar, and the top of the telescopic push rod is fixedly connected to the inner wall of the traction bracket. Both ends of the take-up roller are connected to toothed discs that are adapted to the arc-shaped racks. A traction device is provided. In use, the workpiece is hoisted by the hoisting base, and then the traction motor drives the take-up roller to rotate. The take-up roller rotates and winds up the steel rope, which in turn lifts the hoisting base and the workpiece on the hoisting base. When the workpiece rises to a suitable height, the telescopic push rod drives the connecting crossbar to descend, and the connecting crossbar drives the arc-shaped rack to descend. The arc-shaped rack engages with the toothed discs to fix the toothed discs, thereby fixing the take-up roller. This allows the traction motor to be protected by the cooperation of the arc-shaped racks and toothed discs when the hoisting base is fixed at a suitable height, avoiding damage caused by continuous torsional force on the traction motor. The device provides good protection.

[0008] Preferably, the take-up roller is fixedly connected to a steel rope, and the end of the steel rope away from the take-up roller is fixedly connected to the top of the hoisting base.

[0009] Preferably, the top of the traction bracket is fixedly connected to the top of the traction top seat, and the arc-shaped rack can mesh with the gear disc.

[0010] Preferably, both ends of the connecting crossbar are fixedly connected to limiting devices. The limiting devices include limiting slides, with limiting balls slidably connected to the inner wall of the limiting slides. A limiting ball shell is sleeved and slidably connected to the outer side of the limiting ball. Inclined support rods are fixedly connected to both sides of the limiting slides. When the connecting crossbar moves up and down under the drive of the telescopic push rod, it drives the limiting ball shell to move up and down. The limiting ball shell drives the limiting ball to move up and down. While the limiting ball slides up and down inside the limiting slide, it can be limited by the limiting slide, avoiding the torsional force on the arc-shaped rack from causing the telescopic push rod to become skewed, thus making the meshing between the arc-shaped rack and the gear plate more stable.

[0011] Preferably, the top of the limiting slide is fixedly connected to the connecting crossbar, and the end of the inclined support rod away from the limiting slide is fixedly connected to the top of the connecting crossbar.

[0012] Preferably, the side of the limiting ball shell away from the limiting ball is fixedly connected to the end of the connecting crossbar, and the inner wall of the limiting slide is set as an arc shape adapted to the line limiting ball.

[0013] Preferably, the positioning device includes a positioning seat, a telescopic rod is fixedly connected to the top of the positioning seat, a pressing plate is fixedly connected to the top of the telescopic rod, a pressing pad is fixedly connected to the top of the pressing plate, a pressure control device is provided above the pressing pad, and arc-shaped springs are fixedly connected to both sides of the bottom of the pressing plate, with the end of the arc-shaped spring away from the pressing plate being fixedly connected to the top of the positioning seat.

[0014] Preferably, the bottom of the positioning seat is fixedly connected to the top of the hoisting base. Multiple positioning devices are provided and evenly distributed on the top of the hoisting base. The top of the pressure control device is fixedly connected to the bottom of the traction top seat. The pressure control device can control the traction motor to shut down based on the pressure received. With the positioning device, when the hoisting base rises, it drives the positioning device to rise as well. The squeezing plate inside the positioning device causes the squeezing pad to press against the pressure control device. As the hoisting base continues to rise, the arc spring is compressed, and the pressure on the pressure control device gradually increases. When the pressure on the pressure control device reaches a certain level, it controls the traction motor to shut down. At this point, the friction between the squeezing pad and the pressure control device can fix the hoisting base, thereby preventing the hoisted workpiece from shaking and making the workpiece more stable during hoisting and transfer.

[0015] Preferably, the pressure control device includes a control ring, an arc-shaped limiting plate is slidably connected through the top of the control ring, a connecting bracket is fixedly connected to the inner wall of the control ring, and a top block is fixedly connected to the top of the connecting bracket at the end away from the control ring.

[0016] Preferably, the top of the arc-shaped limiting plate is fixedly connected to the bottom of the traction top seat, and a pressure detector is fixedly connected to the part of the bottom of the traction top seat facing the top block. A pressure control device is provided. When the control ring is squeezed by the compression pad, the control ring drives the top block to move upward through the connecting bracket, so that the top block is squeezed on the pressure detector. As the control ring rises, the pressure on the pressure detector gradually increases. When the pressure on the pressure detector reaches a certain level, the traction motor is controlled to shut down. This allows for automatic control of the traction motor to shut down through pressure, making the positioning device more reliable and controlling the maximum value of the extrusion pressure. This also helps protect the internal connecting components of the positioning device, ensuring safe and reliable use.

[0017] This invention provides a traction device for machining electromechanical equipment. It has the following advantages:

[0018] 1. A traction device for machining electromechanical equipment is provided. In use, the workpiece is hoisted by a hoisting base, and then a traction motor drives a take-up roller to rotate. The rotating take-up roller rotates and winds up a steel rope, which in turn lifts the hoisting base and the workpiece on the hoisting base. When the workpiece rises to a suitable height, a telescopic push rod drives a connecting crossbar to descend. The connecting crossbar drives an arc-shaped rack to descend, and the arc-shaped rack engages with a toothed disc to fix the toothed disc, thereby fixing the take-up roller. This allows the traction motor to be protected by the arc-shaped rack and toothed disc when the hoisting base is fixed at a suitable height, preventing damage from continuous torsional forces. The device provides good protection.

[0019] 2. The traction device for processing electromechanical equipment is equipped with a limit device. When the connecting crossbar moves up and down under the drive of the telescopic push rod, it drives the limit ball shell to move up and down. The limit ball shell drives the limit ball to move up and down. While the limit ball slides up and down inside the limit slide, it can be limited by the limit slide, so as to avoid the torsional force on the arc-shaped rack causing the telescopic push rod to become skewed, making the meshing between the arc-shaped rack and the gear plate more stable.

[0020] 3. This traction device for machining electromechanical equipment is equipped with a positioning device. When the lifting base rises, it drives the positioning device to rise as well. The squeezing plate inside the positioning device squeezes the squeezing pad onto the pressure control device. As the lifting base continues to rise, the arc spring is compressed and contracts. At the same time, the pressure on the pressure control device gradually increases. When the pressure on the pressure control device reaches a certain level, the traction motor is shut off. At this time, the lifting base can be fixed by the friction between the squeezing pad and the pressure control device, thereby preventing the lifting workpiece from shaking and making the workpiece more stable during lifting and transfer.

[0021] 4. This traction device for machining electromechanical equipment is equipped with a pressure control device. When the control ring is squeezed by the extrusion pad, the control ring drives the top block to move upward through the connecting bracket, so that the top block presses against the pressure detector. As the control ring rises, the pressure on the pressure detector gradually increases. When the pressure on the pressure detector reaches a certain level, the traction motor is controlled to shut down. This allows for automatic control of the traction motor's shutdown through pressure, making the positioning device more reliable in its fixation. It also controls the maximum value of the extrusion pressure, which helps protect the internal connecting components of the positioning device, ensuring safe and reliable use.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1:

[0033] Please see Figures 1-4 The present invention provides a technical solution: a traction device for processing electromechanical equipment, including a traction top seat 1, a traction device 2 fixedly connected to the bottom of the traction top seat 1, a hoisting base 3 fixedly connected to the bottom of the traction device 2, and a positioning device 4 fixedly connected to the top of the hoisting base 3.

[0034] The traction device 2 includes:

[0035] The take-up roller 21 has a circular cylindrical structure and a traction bracket 22 disposed outside the take-up roller 21. Both ends of the take-up roller 21 pass through the traction bracket 22 and are rotatably connected to the traction bracket 22. A traction motor 23 is fixedly connected to one side of the traction bracket 22, and the drive shaft of the traction motor 23 is fixedly connected to the end of the take-up roller 21.

[0036] The connecting crossbar 24 has a flat structure and arc-shaped racks 25 at both ends of the connecting crossbar 24. The top of the arc-shaped racks 25 is fixedly connected to the bottom of the connecting crossbar 24. A telescopic push rod 26 is fixedly connected to the top of the connecting crossbar 24. The top of the telescopic push rod 26 is fixedly connected to the inner wall of the traction bracket 22. Both ends of the take-up roller 21 are connected with toothed discs 27 that are adapted to the arc-shaped racks 25.

[0037] The take-up roller 21 is fixedly connected to a steel rope 28, and the end of the steel rope 28 away from the take-up roller 21 is fixedly connected to the top of the hoisting base 3.

[0038] The top of the traction bracket 22 is fixedly connected to the top of the traction top seat 1, and the arc-shaped rack 25 can mesh with the gear plate 27.

[0039] Equipped with a traction device 2, the workpiece is hoisted via the lifting base 3. Then, the traction motor 23 drives the take-up roller 21 to rotate, which in turn winds up the steel rope 28. The steel rope 28 lifts the lifting base 3 and the workpiece on it. When the workpiece reaches a suitable height, the telescopic push rod 26 lowers the connecting crossbar 24, which in turn lowers the arc-shaped rack 25. The arc-shaped rack 25 engages with the gear disc 27 to fix the gear disc 27, thereby fixing the take-up roller 21. This design allows the traction motor 23 to be protected when the lifting base 3 is fixed at a suitable height, preventing damage from continuous torsional forces. The protection is quite good.

[0040] Example 2:

[0041] Please see Figures 1-5Based on Embodiment 1, the present invention provides a technical solution: Both ends of the connecting crossbar 24 are fixedly connected to limiting devices 29. Each limiting device 29 includes a limiting slide 291, with a limiting ball 292 slidably connected to the inner wall of the limiting slide 291. A limiting ball shell 293 is sleeved and slidably connected to the outer side of the limiting ball 292. Diagonal support rods 294 are fixedly connected to both sides of the limiting slide 291. The top of the limiting slide 291 is fixedly connected to the connecting crossbar 24, and one end of the diagonal support rod 294 away from the limiting slide 291 is fixedly connected to the top of the connecting crossbar 24. The end of the limiting ball shell 293 away from the limiting ball 292... The side is fixedly connected to the end of the connecting crossbar 24. The inner wall of the limiting slide 291 is set to be an arc shape that matches the line limiting ball 292. A limiting device 29 is provided. When the connecting crossbar 24 moves up and down under the drive of the telescopic push rod 26, it drives the limiting ball shell 293 to move up and down. The limiting ball shell 293 drives the limiting ball 292 to move up and down. While the limiting ball 292 slides up and down inside the limiting slide 291, it can be limited by the limiting slide 291 to avoid the torsional force on the arc rack 25 causing the telescopic push rod 26 to become skewed. This makes the meshing of the arc rack 25 and the toothed disc 27 more stable.

[0042] Example 3:

[0043] Please see Figures 1-7 Based on Embodiments 1 and 2, the present invention provides a technical solution: the positioning device 4 includes a positioning seat 41, a telescopic rod 42 fixedly connected to the top of the positioning seat 41, a pressing plate 43 fixedly connected to the top of the telescopic rod 42, a pressing pad 44 fixedly connected to the top of the pressing plate 43, a pressure control device 45 disposed above the pressing pad 44, and arc-shaped springs 46 fixedly connected to both sides of the bottom of the pressing plate 43. The end of the arc-shaped spring 46 away from the pressing plate 43 is fixedly connected to the top of the positioning seat 41. The bottom of the positioning seat 41 is fixedly connected to the top of the lifting base 3. Multiple sets of positioning devices 4 are evenly distributed on the top of the lifting base 3. The top of the pressure control device 45 is fixedly connected to the bottom of the traction top seat 1. The pressure control device 45 can control the traction motor 23 to shut down by adjusting the pressure it receives. A positioning device 4 is provided; when the lifting base 3 rises, it drives the positioning device 4 to rise as well. The squeezing plate 43 inside the positioning device 4 causes the squeezing pad 44 to press against the pressure control device 45. As the lifting base 3 continues to rise, the arc spring 46 is compressed and contracts, while the pressure on the pressure control device 45 gradually increases. When the pressure on the pressure control device 45 reaches a certain level, it controls the traction motor 23 to shut down. At this point, the friction between the squeezing pad 44 and the pressure control device 45 can fix the lifting base 3 in place, thus preventing the workpiece from shaking and making the workpiece more stable during lifting and transfer.

[0044] Example 4:

[0045] Please see Figures 1-8 Based on Embodiments 1, 2, and 3, the present invention provides a technical solution: a pressure control device 45 includes a control ring 451, an arc-shaped limiting plate 452 that is slidably connected through the top of the control ring 451, a connecting bracket 453 that is fixedly connected to the inner wall of the control ring 451, a top block 454 that is fixedly connected to the top of the end of the connecting bracket 453 away from the control ring 451, the top of the arc-shaped limiting plate 452 that is fixedly connected to the bottom of the traction top seat 1, and a pressure detector 455 that is fixedly connected to the bottom of the traction top seat 1 opposite to the top block 454. A pressure control device 45 is provided, and when the control ring... When 451 is squeezed by the compression pad 44, the control ring 451 drives the top block 454 to move upward through the connecting bracket 453, so that the top block 454 is squeezed on the pressure detector 455. As the control ring 451 rises, the pressure on the pressure detector 455 gradually increases. When the pressure on the pressure detector 455 reaches a certain level, the traction motor 23 is controlled to shut down. This allows for automatic control of the traction motor 23 to shut down, making the positioning device 4 more reliably fixed and controlling the maximum value of the squeezing force. This also helps protect the internal connecting components of the positioning device 4, ensuring safe and reliable use.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
