Description

Technical Field

[0001] This invention relates to a hoisting frame, specifically a hoisting frame for power equipment, and belongs to the field of power equipment hoisting application technology. Background Technology

[0002] Lifting frame is a general term for the installation and positioning of equipment by cranes or hoisting mechanisms. Lifting frames are required for the lifting and installation of electrical equipment.

[0003] Power equipment is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. It converts primary energy from nature into electricity through power generation devices, and then supplies the electricity to various users through transmission, transformation, and distribution. It mainly includes two categories: power generation equipment and power supply equipment. Power generation equipment mainly includes power plant boilers, steam turbines, gas turbines, water turbines, generators, joggers, transformers, etc. Power supply equipment mainly includes transmission lines of various voltage levels, instrument transformers, contactors, etc.

[0004] In the patent document "CN202221769209.0 A Lifting Frame for Power Equipment," a support plate supports the lifting plate, and a rotating conveyor belt moves the lifting plate upwards. However, when lifting power equipment, which is mainly large and expensive, the stability during lifting is crucial to ensure safe operation. Existing lifting frames struggle to guarantee stable lifting and lowering of the equipment. Furthermore, after lifting, the equipment needs to be moved for installation, which is inconvenient. Using the lifting frame to move the equipment to the platform can easily cause swaying, increasing safety risks. The equipment is also difficult to secure quickly before lifting, making it prone to displacement and damage during the lifting process, thus reducing safety. Currently, there is no structurally sound and reliable lifting frame that can guarantee lifting stability and allow for rapid securing of the equipment. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application employs a crossbeam for the hoisting of electrical equipment and guides the ropes by installing pulleys at the bottom of the sliding plate. This enables the electrical equipment to be moved horizontally during hoisting, facilitating quick operation after the equipment is lifted and placed on the platform. This improves hoisting efficiency and ensures stable lifting of the equipment, thus enhancing hoisting stability.

[0006] To further address the problems in existing technologies, the system protects the electrical equipment by setting up a housing and supports it by setting up a base. The housing and base work together to achieve rapid fixing. During hoisting, the weight of the electrical equipment pulls the pallet to move, providing support on both sides of the base, which further ensures the safety of hoisting.

[0007] To further address the problems in the existing technology: during the lifting process, the movement of the lifting plate can drive the rotation of the clamping plate. The cooperation between the clamping plate and the buffer pad can limit the movement of the power equipment, ensuring the stability of the power equipment during lifting. Furthermore, by setting up pull ropes to pull the box, the box can be limited, achieving stability during the lifting process, preventing the box from shaking, and improving the stability performance of the power equipment lifting.

[0040] Reference Figures 1 to 10 The power equipment hoisting frame includes: a hoisting frame consisting of a base plate 1, an upright plate 2 and a crossbeam 3, as well as a hoisting structure for fixing the power equipment.

[0041] Reference Figures 1 to 4 as well as Figure 10As a specific solution, a vertical plate 2 is fixedly installed on the top of the base plate 1. One side of the vertical plate 2 is fixedly connected to the crossbeam 3, and a first pull rope 9 is provided on the other side of the vertical plate 2. The bottom of the crossbeam 3 is fixedly connected to the side wall of the vertical plate 2 through a guide rail 12. The guide rail 12 is located below the crossbeam 3 and is inserted through the slide plate 13. A first pulley 14 is rotatably connected to the bottom of the slide plate 13 to adjust the horizontal position of the first pull rope 9. The slide plate 13 can be moved by setting the guide rail 12. The slide plate 13 is pulled by the second pull rope 19 to slide on the surface of the guide rail 12, thereby adjusting the horizontal position during the lifting process. It can be lifted and moved outward at the same time, which makes it convenient to place the box 11 and the base 31 on the hoisting platform without moving the entire hoisting frame for construction. This solves the problem of swaying of electrical equipment when the traditional hoisting frame is moved. After the box 11 is lifted to a certain height, the operator does not need to pull one side of the box 11, which improves the convenience of hoisting.

[0042] Reference Figures 1 to 9 As a preferred embodiment, the hoisting structure includes a lifting plate 10 and a housing 11. The lifting plate 10 is fixedly connected to the bottom end of the first pull rope 9. The bottom of the lifting plate 10 is fixedly connected to the limiting block 21 via a connecting rod 20, and the connecting rod 20 is inserted through the top of the housing 11. The ends of the lifting plate 10 are fixedly connected to the limiting rod 24 and the traction rope 29, respectively. The inner wall of the housing 11 is rotatably connected to the clamping plate 22. The bottom side wall of the clamping plate 22 is fixedly connected to the buffer pad 23 to facilitate limiting the electrical equipment. The top of the clamping plate 22 is inserted through the limiting rod 24, and the limiting rod 24 has a T-shaped structure. The outer wall of the housing 11 is fixedly connected to the connecting piece 25, and the connecting piece 25 is connected to the support plate 21. The 6-rotatable connection is provided, and the support plate 26 is fixedly connected to the bottom of the traction rope 29. The side wall of the box 11 is provided with a hook-shaped slot 30. The box 11 is provided with a base 31 for supporting the power equipment. The side end of the base 31 is fixedly connected to the fixing rod 33 through the side plate 32, and the fixing rod 33 is engaged and slidably inserted into the slot 30. The cooperation between the lifting plate 10 and the box 11 can realize the quick fixation of the power equipment before hoisting. After the base 31 and the power equipment are placed and positioned in sequence, the quick hoisting operation can be realized, which improves the convenience of hoisting. At the same time, the cooperation between the lifting plate 10 and the box 11 can achieve stable support and fixation of the power equipment, which is conducive to improving the stability of hoisting.

[0043] Reference Figures 1 to 4As an extension, the upright plate 2 is located on one side of the base plate 1, and the base plate 1 and the crossbeam 3 are both located on the same side of the upright plate 2. The crossbeam 3 has a U-shaped cross section, and both ends of the crossbeam 3 are fixedly connected to the top of the upright plate 2 through reinforcing rods 4. The base plate 1 and the upright plate 2 are both fixedly connected to the first winch 7. The output end of the first winch 7 is fixedly connected to the first roller 8, and the first roller 8 is connected to the first pull rope 9. The crossbeam 3 has improved structural stability through the reinforcing rods 4, and the first pull rope 9 on the crossbeam 3 and the upright plate 2 serves as the main traction force during hoisting, used for hoisting the box 11 and its internal electrical equipment.

[0044] Reference Figures 1 to 4 In this configuration, the top of the upright plate 2 is rotatably connected to the first guide wheel 5, and the outer end of the crossbeam 3 is rotatably connected to the second guide wheel 6. The surfaces of the first guide wheel 5 and the second guide wheel 6 are both provided with first pull ropes 9. A crossbar 15 is fixedly installed inside the crossbeam 3, and the middle part of the crossbar 15 is rotatably connected to the second pulley 16. The first guide wheel 5 and the second guide wheel 6 are used for stable guidance of the first pull rope 9. The second pulley 16 can guide the second pull rope 19, and at the same time, the second pull rope 19 pulls the slide plate 13 to slide on the surface of the guide rail 12.

[0045] Reference Figures 1 to 2 as well as Figure 4 As a specific solution, the side wall of the upright plate 2 is fixedly connected to the second winch 17, the output end of the second winch 17 is fixedly connected to the second roller 18, the surface of the second roller 18 and the second pulley 16 are both provided with a second pull rope 19, and the other end of the second pull rope 19 is fixedly connected to the middle of the slide plate 13.

[0046] Reference Figures 1 to 7 as well as Figure 9 As a specific embodiment, the lifting plate 10 is fitted and connected to the top surface of the housing 11. The lifting plate 10 has a cross-shaped structure. Limiting rods 24 are symmetrically distributed at both ends of the lifting plate 10, and traction ropes 29 are symmetrically distributed at the other two ends of the lifting plate 10. The traction ropes 29 are located on the outside of the housing 11, and the limiting rods 24 are located inside the housing 11. The housing 11 has two bent clamping plates 22 inside. The bottom of each clamping plate 22 is connected to the inner wall of the housing 11 by a tension spring 39. When the lifting plate 10 moves upward and separates from the top surface of the box 11, it can drive the limiting rod 24 to move. The limiting rod 24 contacts the inclined surface of the clamping plate 22 and pushes it to rotate. Due to the presence of the power equipment, the clamping plate 22 overcomes the elasticity of the tension spring 39 and rotates, thereby limiting the power equipment. After the lifting is completed, the elasticity of the tension spring 39 pulls the clamping plate 22 to reset. When the box 11 is suspended, the clamping plate 22 can still be in its original state to facilitate the box 11 to be smoothly fitted onto the power equipment.

[0047] Reference Figure 1 , Figure 3 as well as Figures 5 to 8 In this configuration, the outer wall of the housing 11 is fixedly connected to the guide block 28, and the guide block 28 is internally connected to the traction rope 29. The outer wall of the housing 11 is connected to the support plate 26 via a spring 27. The support plate 26 has an L-shaped structure, with its bottom horizontal end located below the housing 11. The support plates 26 are symmetrically distributed to the bottom of the base 31. The guide block 28 can be used to achieve horizontal tension in the traction rope 29. By pulling the support plate 26 with the traction rope 29, the bottom horizontal end of the support plate 26 moves to the bottom of the housing 11 and contacts both ends of the base 31. At this time, the cooperation between the slot 30 and the fixing rod 33, as well as the support plate 26, provide synchronous support, ensuring the stability of the base 31 during lifting and improving safety performance.

[0048] Reference Figures 1 to 2 as well as Figure 4 and Figure 7 In this design, openings 38 are provided on both sides of the base plate 1, the distance between the two openings 38 is less than the length of the box body 11, and a support plate 26 is provided inside each of the two openings 38. The box body 11 is located on the surface of the base plate 1, and the cross-section of the box body 11 is a square hollow structure. Figure 7 As shown, the opening 38 can be used to rotate the tray 26, allowing the tray 26 to move smoothly under the base 31.

[0049] Reference Figure 2 and Figure 6 In this design, the base 31 has symmetrically distributed side plates 32 at both ends. The length of the base 31 is the same as the length of the box 11. The base 31 has a rectangular structure. Two T-shaped fixing rods 33 extend outward from both sides of the base 31. Each fixing rod 33 is slidably connected to the inside of the slot 30. By setting the base 31 to a rectangular structure and placing the side plates 32 at the narrow side of the base 31, the box 11 can drive the slot 30 to move at the fixing rods 33.

[0050] Reference Figure 1 As a specific solution, the side wall of the upright plate 2 is fixedly connected to the third motor 34, the output end of the third motor 34 is fixedly connected to the third roller 35, the surface of the third roller 35 is connected to the third pull rope 36, the other end of the third pull rope 36 is fixedly connected to the box body 11, and a gravity block 37 is movably threaded through the surface of the third pull rope 36. The third motor 34 is used to drive the third pull rope 36 to wind up and down on the surface of the third roller 35, so that the distance between the third pull rope 36 and the two sides of the box body 11 can be adjusted, so as to realize the synchronous unwinding of the third pull rope 36 during the hoisting process, and cooperate with the gravity block 37 to keep the box body 11 in a stable state, so as to avoid the problem of the box body 11 rotating during the hoisting process.

[0051] Reference Figures 1 to 4 As a specific embodiment, the crossbeam 3 is arranged with an inclined structure. Two guide rails 12 are provided at the bottom of the crossbeam 3. Each guide rail 12 is parallel to the crossbeam 3 and symmetrically distributed to both ends of the crossbeam 3. The two guide rails 12 are slidably connected to the inner ends of the slide plate 13, and the slide plate 13 is slidably connected to the bottom of the crossbeam 3. The cooperation between the crossbeam 3 and the guide rails 12 enables the slide plate 13 to move stably. The slide plate 13 drives the first pulley 14 to adjust its position, thereby adjusting the vertical end of the bottom of the first pull rope 9 in the horizontal direction.

[0052] In the technical solution of this application, the entire power equipment hoisting frame uses a crossbeam 3 for hoisting the power equipment. Before hoisting, the base 31 is placed on the base plate 1, with both ends of the base 31 located at the opening 38. The power equipment is placed in the middle of the base 31. The first winch 7 drives the first roller 8 to rotate, causing the first pull rope 9 to be positioned under the housing 11 on the first guide wheel 5 and the second guide wheel 6, so that both the base 31 and the power equipment are located inside the housing 11. At this time, the housing 11 contacts the base plate 1, and the fixing plate moves into the slot 30. The second winch 17 drives the second roller 18 to rotate, causing the second pull rope 19 to move on the second pulley 16. The second pull rope 19 pulls the slide plate 13 to slide on the guide rail 12, thereby adjusting the position of the first pulley 14 to change the horizontal position of the box 11, so that the slot 30 at the bottom of the box 11 can be accurately connected with the fixed rod 33. At this time, the lifting plate 10 is located at the top of the box 11, and the traction rope 29 is in a slack state.

[0053] During lifting, the first winch 7 operates, causing the first pull rope 9 to pull the lifting plate 10 upwards. This, in turn, causes the lifting plate 10 to pull the traction rope 29 taut. As the traction rope 29 moves within the guide block 28, it pulls the pallet 26 to rotate, causing the pallet 26 to move from the opening 38... Figure 7 Rotate as shown Figure 6 The state shown is ( Figure 7(The dashed line represents the movement trajectory of the far end of the support plate 26.) At this time, the spring 27 is in a compressed state, and the lifting plate 10 simultaneously drives the limiting rod 24 to move upward, causing the limiting rod 24 to push the clamping plate 22 to rotate, so that the clamping plate 22 drives the buffer pad 23 to clamp the two sides of the power equipment. At this time, the tension spring 39 is in a stretched state. When the lifting plate 10 drives the connecting rod 20 to move, it drives the limiting rod 24 to contact the top of the box 11, thereby driving the box 11 to be lifted simultaneously. The box 11 achieves the synchronous lifting of the base 31 through the cooperation of the fixing rod 33 and the slot 30, as well as the cooperation of the support plate 26 and the base 31, thereby realizing the synchronous lifting of the power equipment and the box 11. The box 11 is placed and lifted stably. The second pull rope 19 pulls the slide plate 13 to move and adjust the position of the first pulley 14 to change the horizontal position of the box 11 during lifting, so as to facilitate the lifting of the box 11 and the base 31 onto the platform for installation. During the lifting process, the third motor 34 drives the third roller 35 to rotate, so that the third roller 35 drives the third pull rope 36 to pull the two sides of the box 11. The box 11 is stabilized by setting the gravity block 37. When the box 11 shakes and rotates, it can be restricted by the third pull rope 36 and the gravity block 37, which helps to improve the stability of the hoisting frame.

[0054] The above are merely specific embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
