Description

Technical Field

[0001] This utility model relates to a winch maintenance lifting platform, and more particularly to a winch maintenance lifting platform, belonging to the technical field of winch maintenance lifting platforms. Background Technology

[0002] Winches are core hoisting equipment in industries such as mining, ports, construction, and oil drilling. They are mainly used for traction of heavy objects, transportation of personnel, or lifting of materials (such as mine hoists, port hoists, and construction winches). Their working environment is complex and they operate under high loads for a long time, which makes mechanical parts (such as wire ropes, braking devices, transmission gears, and bearings) prone to wear, breakage, and corrosion. Regular maintenance and repair are required. According to statistics, the annual downtime of mine winches in my country is about 15%-20%, of which more than 40% of downtime is due to low maintenance efficiency and insufficient safety, which directly affects production efficiency and operational safety.

[0003] Winch maintenance requires personnel to approach its core components (such as drums, gearboxes, and sheave assemblies) for disassembly, inspection, or replacement. Traditional maintenance methods rely on manually erecting scaffolding, simple lifting ladders, or general lifting equipment. However, traditional scaffolding requires manual construction layer by layer and has poor stability; simple lifting ladders lack fall protection, leading to frequent falls. Furthermore, winch maintenance often involves narrow spaces, high-altitude operations, or dusty / oily environments. Manually moving tools and parts requires climbing or using unstable ladders, which can easily lead to personnel fatigue and operational errors (such as loose bolts or falling tools causing injury).

[0004] Therefore, there is an urgent need to improve a winch maintenance lifting platform to solve the aforementioned problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in this embodiment, a winch maintenance lifting platform embodiment is provided.

[0026] A winch maintenance lifting platform includes a base support 1 and a platform body 2. A lifting structure 3 is mounted on the base support 1. The lifting structure 3 includes a drive motor 4 fixedly mounted on the top of the base support 1. A first helical gear 5 is fixedly mounted on the output end of the drive motor 4. A support frame 6 is fixedly mounted on the base support 1. A lead screw 7 connected to the base support 1 is movably mounted on the support frame 6. A second helical gear 8 meshing with the first helical gear 5 is fixedly mounted on one end of the lead screw 7. A transmission block 9 connected to the platform body 2 is mounted on the lead screw 7. A guardrail 10 is mounted on the top of the platform body 2. An entrance / exit gate 11 is provided at one end of the guardrail 10. Multiple casters 12 are mounted on the bottom of the base support 1. Multiple sliders 13 are mounted on the platform body 2. Slide rails 14 connected to the sliders 13 are fixedly mounted on both sides of the base support 1.

[0027] By setting up the lifting structure 3, the traditional method of manually building scaffolding, simple lifting ladders, or general lifting equipment for winch maintenance is changed, eliminating the need for personnel to build layer by layer and greatly improving stability. When the platform body 2 is not raised, personnel first enter the interior of the guardrail 10 by opening the access door 11, and then close and lock the access door 11 to prevent operators from falling from the guardrail 10. When the height required for winch maintenance exceeds the platform body 2, the drive motor 4 is started to drive the first helical gear 5 to start rotating. Due to the connection between the first helical gear 5 and the second helical gear 8, the second helical gear 8 also starts to rotate at the same time as the first helical gear 5 rotates. At this time, the lead screw 7... Driven by the second helical gear 8, it also begins to rotate synchronously, causing the transmission block 9 to move and rise on the lead screw 7. When the transmission block 9 rises, it can drive the platform body 2 to rise. When the platform body 2 rises to the appropriate position, the operation of the drive motor 4 can be stopped. At the same time, with the cooperation of the slider 13 and the slide rail 14, the rising process of the platform body 2 can be made smoother, thereby reducing the wear between the platform body 2 and the base support 1. The position of the platform body 2 can be adjusted by multiple moving wheels 12, making maintenance easier for personnel. The advantage of this structure is that even in narrow spaces, high-altitude operations, or dusty / oily environments, manual handling of tools and parts will not result in personnel fatigue leading to operational errors.

[0028] like Figures 1-6 As shown, a protective shell 15 is fixedly installed on the outside of the drive motor 4. The protective shell 15 has multiple heat dissipation holes 16. A maintenance cover 17 is provided at one end of the protective shell 15. A first magnetic ring 18 is fixedly installed on the inner side of the maintenance cover 17. A second magnetic ring 19, which is magnetically connected to the first magnetic ring 18, is fixedly installed at one end of the protective shell 15.

[0029] The protective shell 15, heat dissipation holes 16, and inspection cover 17 effectively protect the drive motor 4, preventing damage from accidental contact. The multiple heat dissipation holes 16 on the protective shell 15 dissipate heat generated by the drive motor 4, preventing overheating and potential malfunction. The inspection cover 17 allows personnel to inspect the drive motor 4 without disassembling the protective shell 15, saving time. The first magnetic ring 18 and the second magnetic ring 19 attract each other, securing the inspection cover 17 to the protective shell 15 and preventing it from falling off. Due to the characteristics of the first and second magnetic rings, the inspection cover 17 can be opened by pulling it without tools, further saving time.

[0030] like Figures 1-6As shown, the platform body 2 has a slot 20 adapted to the guardrail 10. Both the platform body 2 and the guardrail 10 have multiple connecting holes 21. A plug rod 22 is movably installed inside the connecting hole 21. A latch 23 is fixedly installed at one end of the plug rod 22. Multiple grooves that cooperate with the latch 23 are opened on the inner side of the connecting hole 21. Multiple fixing plates 24 are fixedly installed on both sides of the platform body 2. A first electric telescopic rod 25 is fixedly installed on one side of the latch 23. A first control switch 26 is provided on the first electric telescopic rod 25. The output end of the first electric telescopic rod 25 is equipped with a locking tooth 27, and the other end of the insertion rod 22 is fixedly equipped with a toothed ring 28 that meshes with the locking tooth 27. A fixing block 29 is fixedly installed on the first electric telescopic rod 25. A fixing sleeve 30 connected to the fixing block 29 is fixedly installed at one end of the locking tooth 27. The fixing block 29 has multiple mounting holes 31. A spring 32 is fixedly installed inside the mounting holes 31. A locking ball 33 is fixedly installed at one end of the spring 32. Multiple locking holes 34 that cooperate with the locking ball 33 are opened on the inner side of the fixing sleeve 30.

[0031] With the design of the slot 20, connecting hole 21, insert rod 22, latch 23, and groove, the guardrail 10 is inserted into the slot 20, and then the insert rod 22 is inserted into the connecting hole 21 to connect the guardrail 10 and the platform body 2. The insert rod 22 is then rotated to engage the latch 23 in the groove inside the connecting hole 21, thus fixing the platform body 2 and the guardrail 10 together and preventing them from falling off. Rotating the insert rod 22 to disengage the latch 23 from the groove allows the insert rod 22 to be pulled out of the connecting hole 21, at which point the guardrail 10 can be removed from the platform body 2, facilitating disassembly and replacement when the guardrail 10 is damaged.

[0032] With the arrangement of the fixing plate 24, the first electric telescopic rod 25, the first control switch 26, the locking tooth 27, and the toothed ring 28, when the insertion rod 22 is inserted into the connecting hole 21, the first control switch 26 is used to extend the first electric telescopic rod 25. When the first electric telescopic rod 25 extends, it drives the locking tooth 27 to move and engage with the toothed ring 28, thereby limiting the insertion rod 22 and greatly improving its stability inside the connecting hole 21. When the first electric telescopic rod 25 is retracted by the first control switch 26, the locking tooth 27 disengages from the toothed ring 28, allowing personnel to rotate the insertion rod 22 normally. (The last sentence appears to be incomplete and possibly refers to a different mechanism.) The arrangement of the fixing sleeve 30, mounting hole 31, spring 32, locking ball 33, and locking hole 34 allows the locking ball 33 to be compressed and contracted into the mounting hole 31 during the insertion of the fixing block 29 into the fixing sleeve 30. When the locking ball 33 moves to the position of the locking hole 34, it can be locked into the locking hole 34 under the elastic action of the spring 32, thereby fixing the fixing block 29 inside the fixing sleeve 30 to prevent it from falling off. When the personnel pull the locking tooth 27, the locking ball 33 will be compressed and contracted into the mounting hole 31. When the locking ball 33 is disengaged from the locking hole 34, the locking tooth 27 can be removed from the first electric telescopic rod 25, thus facilitating the disassembly and replacement of the locking tooth 27 when it is damaged.

[0033] like Figures 1-6 As shown, multiple support plates 35 are fixedly installed on the side of the base bracket 1. A fixing frame 36 is fixedly installed on the top of the support plate 35. A second electric telescopic rod 37 is fixedly installed on the bottom of the fixing frame 36. A suction cup 38 is fixedly installed at the output end of the second electric telescopic rod 37. A through hole 39 adapted to the suction cup 38 is opened on the support plate 35. A second control switch 40 is fixedly installed on one side of the second electric telescopic rod 37.

[0034] With the support plate 35, the fixing frame 36, the second electric telescopic rod 37, the suction cup 38, the through hole 39, and the second control switch 40, the second control switch 40 is controlled to make the second electric telescopic rod 37 extend, causing the suction cup 38 to begin to descend. When the suction cup 38 is attached to the ground, the extension of the second electric telescopic rod 37 can be stopped by the second control switch 40. After the suction cup 38 is attached to the ground, it can limit the base support 1, preventing the base support 1 from sliding under the action of multiple moving wheels 12 when personnel are maintaining the winch, which may cause personnel to fall. The limit of the suction cup 38 can avoid this risk. When the second electric telescopic rod 37 retracts, the suction cup 38 can be detached from the ground, so that the base support 1 can move and change positions normally.

[0035] In this embodiment, as Figures 1-6 As shown in the figure, the working process of the winch maintenance lifting platform provided in this embodiment is as follows:

[0036] When the platform body 2 is not raised, personnel first enter the interior of the guardrail 10 by opening the access door 11, and then close and lock the access door 11 to prevent the operator from falling off the guardrail 10. When the height that the winch needs to repair exceeds the platform body 2, the drive motor 4 is started to drive the first helical gear 5 to start rotating. Due to the connection between the first helical gear 5 and the second helical gear 8, the second helical gear 8 also starts to rotate at the same time as the first helical gear 5 rotates. At this time, the lead screw 7 also starts to rotate synchronously under the drive of the second helical gear 8, so that the transmission block 9 starts to move and rise on the lead screw 7. When the transmission block 9 rises, it can drive the platform body 2 to rise. When the platform body 2 rises to the appropriate position, the drive motor 4 can be stopped. At the same time, the cooperation of the slider 13 and the slide rail 14 can make the process of the platform body 2 rising smoother, thereby reducing the wear between the platform body 2 and the base support 1. The position of the platform body 2 can be adjusted by multiple moving wheels 12, making personnel maintenance easier.

[0037] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, as previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or techniques or knowledge in related fields.
