Abstract
Description
Technical Field
[0001] This utility model relates to the field of equipment hoisting technology, and in particular to a shock-absorbing and buffering structure for hoisting large equipment. Background Technology
[0002] In large-scale industrial projects such as power, petrochemical, and metallurgy, the installation and maintenance of large power equipment (such as transformers, generators, and high-voltage switchgear) often require hoisting operations. These devices are typically large in size, have concentrated weight, complex internal structures, and are very expensive.
[0003] In existing hoisting processes, equipment is typically suspended at high altitudes and moved over long distances. In this state, its stability directly affects the safety of the equipment itself and the smooth progress of the entire project. A collision or fall could not only result in significant economic losses but also potentially trigger a serious engineering accident.
[0004] Based on the aforementioned technologies, the applicant believes that due to the lack of effective lateral restraint and buffering mechanisms, such swaying can cause the equipment to collide with surrounding building structures, scaffolding, or other equipment, resulting in problems such as deformation of the equipment shell, displacement of internal precision components, or insulation damage. Traditional lifting tools mostly use rigid materials or simple flexible connections, which are difficult to effectively absorb energy under instantaneous impact, further increasing the uncertainty and risk in the lifting process. In response to the above problems, we have introduced a shock-absorbing and buffering structure for lifting large equipment. Utility Model Content
[0005] This utility model discloses a shock-absorbing and buffering structure for hoisting large equipment, aiming to solve the technical problem of buffering and protection during equipment hoisting.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A shock-absorbing and buffering structure for hoisting large equipment includes a hoisting frame. Stabilizing frames are equidistantly fixed to both sides of the bottom inner wall of the hoisting frame. A buffering mechanism is provided inside the hoisting frame, comprising a stabilizing component and an auxiliary component. The stabilizing component and the auxiliary component cooperate with each other. The stabilizing component includes a fixing block fixedly connected inside the stabilizing frame. A telescopic groove is formed inside the fixing block, and a sliding rod is slidably connected inside the telescopic groove. A spring is sleeved on the outer side of the sliding rod, and a limit plate is fixedly connected to the outer side of the sliding rod. A stabilizing column is slidably connected to the top of the stabilizing frame. A connecting column is fixedly connected between the stabilizing column and the sliding rod. A beveled block is fixedly connected to the front of the connecting column. A telescopic column is slidably connected inside the stabilizing frame, and a beveled groove is formed on the outer side of the telescopic column. The beveled groove and the beveled block cooperate with each other. A connecting plate is fixedly connected to the outer side of the telescopic column.
[0008] The buffer mechanism provides lateral constraint and cushioning for the equipment, effectively suppressing its swaying and preventing it from being bumped by hard objects. It has a simple structure and is highly practical.
[0009] In a preferred embodiment, the auxiliary component includes stabilizing plates, which are symmetrically fixedly connected to the bottom two sides of the hoisting frame. T-shaped grooves are equally spaced on the top of both stabilizing plates, and T-shaped sliders are slidably connected inside the T-shaped grooves. A clamping plate is fixedly connected to the end of the telescopic column away from the connecting plate, and the bottom of the clamping plate is fixedly connected to the top of the T-shaped slider.
[0010] By incorporating a stabilizing plate, T-shaped groove, T-shaped slider, and clamping plate, the lateral stability of the equipment is further enhanced. The cooperation between the T-shaped slider and the T-shaped groove allows the clamping plate to move smoothly, achieving flexible clamping of the equipment, avoiding damage caused by rigid contact, and improving adaptability and safety during hoisting.
[0011] In a preferred embodiment, buffer rubber strips are fixedly connected at equal intervals to the bottom of the inner wall of the hoisting frame.
[0012] By installing a buffer rubber strip at the bottom of the inner wall of the hoisting frame, the friction between the equipment and the contact surface is increased, while providing additional cushioning protection and reducing the risk of slippage and collision of the equipment during hoisting.
[0013] In a preferred embodiment, the bottom inner wall of the hoisting frame is symmetrically and fixedly connected with barrier blocks.
[0014] By setting up barrier blocks, the movement range of the equipment within the hoisting frame is effectively limited, preventing the equipment from accidentally sliding out of the hoisting frame and further improving the safety of hoisting operations.
[0015] In a preferred embodiment, lifting holes are symmetrically provided on both sides of the lifting frame.
[0016] By opening lifting holes on both sides of the lifting frame, it is easier to connect and fix the lifting equipment, thereby improving the convenience and efficiency of the lifting operation.
[0017] In a preferred embodiment, the size of the T-shaped slider matches the size of the T-shaped groove, and the T-shaped slider and the T-shaped groove are used in conjunction with each other.
[0018] By ensuring that the dimensions of the T-shaped slider and the T-shaped groove match and cooperate with each other, the movement of the clamping plate is guaranteed to be smooth and reliable, avoiding jamming or displacement, and enhancing the stability and service life of the structure.
[0019] The shock-absorbing and buffering structure for hoisting large equipment provided by this utility model has the following advantages:
[0020] Firstly, the buffer mechanism provides lateral constraint and cushioning for the equipment, effectively suppressing its swaying and preventing it from being bumped by hard objects. The structure is simple and highly practical.
[0021] Secondly, by installing buffer rubber strips at the bottom of the inner wall of the lifting frame, the friction between the equipment and the contact surface is increased, providing additional cushioning protection and reducing the risk of slippage and collision during lifting. The installation of blocking blocks effectively limits the movement range of the equipment within the lifting frame, preventing accidental slippage and detachment, further improving the safety of the lifting operation. Lifting holes on both sides of the lifting frame facilitate the connection and fixation of the lifting equipment, improving the convenience and efficiency of the lifting operation. By ensuring that the dimensions of the T-shaped slider and T-shaped groove match and cooperate with each other, the movement of the clamping plate is ensured to be smooth and reliable, avoiding jamming or displacement, thus enhancing the stability and service life of the structure.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0029] The shock-absorbing and buffering structure for hoisting large equipment disclosed in this utility model is mainly used in equipment hoisting scenarios.
[0030] Reference Figure 1 - Figure 5 A shock-absorbing and buffering structure for hoisting large equipment includes a hoisting frame 1. Stabilizing frames 2 are fixedly connected at equal intervals on both sides of the bottom inner wall of the hoisting frame 1. A buffering mechanism is provided inside the hoisting frame 1, comprising a stabilizing component and an auxiliary component. The stabilizing component and the auxiliary component work together. The stabilizing component includes a fixing block 31, which is fixedly connected inside the stabilizing frame 2. A telescopic groove 32 is provided inside the fixing block 31. A sliding rod 33 is slidably connected inside the telescopic groove 32. A spring 34 is sleeved on the outside of the sliding rod 33. A limit plate 35 is fixedly connected to the outside of the sliding rod 33. A stabilizing column 36 is slidably connected to the top of the stabilizing frame 2. A connecting column 37 is fixedly connected between the stabilizing column 36 and the sliding rod 33. An inclined block 38 is fixedly connected to the front of the connecting column 37. A telescopic column 39 is slidably connected inside the stabilizing frame 2. An inclined groove 310 is provided on the outside of the telescopic column 39. The inclined groove 310 and the inclined block 38 work together. A connecting plate 311 is fixedly connected to the outside of the telescopic column 39. The auxiliary components include stabilizing plates 4, which are symmetrically fixedly connected to the bottom sides of the hoisting frame 1. T-shaped grooves 5 are equally spaced on the top of both stabilizing plates 4. T-shaped sliders 7 are slidably connected inside the T-shaped grooves 5. A clamping plate 6 is fixedly connected to the end of the telescopic column 39 away from the connecting plate 311. The bottom of the clamping plate 6 is fixedly connected to the top of the T-shaped slider 7.
[0031] In this embodiment, the spring 34 inside the fixed block 31 is compressed, and the vertical impact energy is absorbed and dissipated through the cooperation of the sliding rod 33 and the limiting plate 35. Simultaneously, the inclined block 38, fixed to the sliding rod 33 via the connecting column 37, moves accordingly. Its inclined surface interacts with the inclined groove 310 on the telescopic column 39, converting a portion of the vertical impact force into horizontal motion, pushing the telescopic column 39 and the connecting plate 311 fixed to it to move outward. The connecting plate 311 drives the clamping plate 6 to move, while the T-shaped slider 7 at the bottom of the clamping plate 6 slides smoothly along the T-shaped groove 5 on the stabilizing plate 4, allowing the clamping plates 6 on both sides to flexibly clamp the equipment horizontally. Through the buffer mechanism, lateral constraint and buffering are provided for the equipment, effectively suppressing its sway and preventing it from being struck by external hard objects. The structure is simple and highly practical.
[0032] In the above technical solution, considering the issue of equipment hoisting buffer protection, the specific operation is as follows to solve this problem:
[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, buffer rubber strips 8 are fixedly connected at equal intervals to the bottom of the inner wall of the lifting frame 1. Blocking blocks 9 are symmetrically fixedly connected to the bottom of the inner wall of the lifting frame 1. Lifting holes 10 are symmetrically provided on both sides of the lifting frame 1. The size of the T-shaped slider 7 matches the size of the T-shaped groove 5, and the T-shaped slider 7 and the T-shaped groove 5 are used in conjunction with each other.
[0034] In this embodiment, by installing a buffer rubber strip 8 at the bottom of the inner wall of the lifting frame 1, the friction between the equipment and the contact surface is increased, providing additional cushioning protection and reducing the risk of slippage and collision during lifting. By setting up the blocking block 9, the movement range of the equipment within the lifting frame 1 is effectively limited, preventing the equipment from accidentally slipping out of the lifting frame 1, further improving the safety of the lifting operation. Lifting holes 10 are opened on both sides of the lifting frame 1 to facilitate the connection and fixation of the lifting equipment, improving the convenience and efficiency of the lifting operation. By ensuring that the dimensions of the T-shaped slider 7 and the T-shaped groove 5 match and cooperate with each other, the movement of the clamping plate 6 is ensured to be smooth and reliable, avoiding jamming or displacement, and enhancing the stability and service life of the structure.
[0035] Working Principle: During hoisting operations, the equipment is placed inside the hoisting frame 1. When the equipment vibrates or is impacted due to hoisting, movement, or external forces, the impact force is first transmitted to the buffer mechanism inside the stabilizing frame 2. The spring 34 inside the fixed block 31 is compressed, and the vertical impact energy is absorbed and dissipated through the cooperation of the sliding rod 33 and the limiting plate 35. At the same time, the inclined block 38, which is fixed to the sliding rod 33 through the connecting column 37, moves accordingly. Its inclined surface interacts with the inclined groove 310 opened on the telescopic column 39, converting part of the vertical impact force into horizontal movement, pushing the telescopic column 39 and the connecting plate 311 fixed to it to move outward. The connecting plate 311 drives the clamping plate 6 to move, and the T-shaped slider 7 at the bottom of the clamping plate 6 slides smoothly along the T-shaped groove 5 on the stabilizing plate 4, so that the clamping plates 6 on both sides flexibly clamp the equipment in the horizontal direction, providing lateral restraint and buffering, and effectively suppressing the swaying of the equipment. The buffer rubber strip 8 at the bottom of the hoisting frame 1 increases friction and provides bottom cushioning, while the stop block 9 limits the displacement of the equipment within the frame. Through the synergistic effect of spring 34 cushioning, inclined plane force direction conversion, and flexible clamping, this structure achieves multi-dimensional and highly efficient shock absorption and cushioning, significantly improving the stability and safety of the hoisting process for large equipment.
[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
