Description

Technical Field

[0001] This utility model relates to the field of lifting equipment technology, and in particular to a fixed cage for installing generator sets. Background Technology

[0002] In generator set installation projects, large equipment (such as generator stators and rotors) often needs to be vertically hoisted using a lifting cage. Traditional lifting cages are mostly fixed frame structures, which have significant drawbacks: Low loading and unloading efficiency: Equipment needs to be loaded from the side or top of the cage using a forklift or crane, limiting operating space and making it prone to imbalance due to center of gravity shift. If the equipment shifts inside the cage, it needs to be readjusted after being placed on the ground, greatly affecting construction efficiency. Lack of fine-tuning mechanism: Existing lifting cage doors are mostly single-layer designs and can only open outwards. When the equipment tilts during hoisting, operators cannot enter the cage to adjust its position while it is suspended, posing a safety hazard. Insufficient fixing reliability: Some solutions use sliding rails to support the equipment, but lack an effective locking structure. During hoisting, the equipment may slide and impact the cage due to inertia, especially under tilted conditions where rolling friction resistance is low, easily causing equipment damage. Poor hoisting stability: Rigid hoisting structures (such as directly welded hooks) amplify the impact force during crane lifting and lowering, causing the cage to sway and increasing the risk of equipment displacement.

[0003] For example, some existing hoisting cages with rollers still rely on external equipment for loading and unloading, and the problem of adjusting the position of the equipment in a suspended state has not been solved. Therefore, there is an urgent need for a fixed hoisting cage with efficient loading and unloading, dynamic fine-tuning, and multiple locking functions to meet the special working conditions required for generator set installation. Utility Model Content

[0004] The purpose of this invention is to provide a fixed hoisting cage for generator set installation, so as to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fixed cage for installing a generator set includes a cage body, with lifting rings fixedly installed at the four corners of the top of the cage body. A flexibly connected hanging plate is provided at the top of the cage body. A cage door is movably installed on the left side of the cage body. The cage door includes a frame, a first door body, and a second door body. The first door body is movably installed inside the frame, and a mounting frame for installing the second door body is provided on the first door body. The second door body is movably installed inside the mounting frame. The opening and closing direction of the first door body is to rotate towards the outside of the cage body, and the opening and closing direction of the second door body is to rotate towards the inside of the cage body.

[0007] By adopting the above technical solution, the first door opens to the outside of the cage so that the device can be better placed inside the cage, and the second door opens to the inside of the cage so as to facilitate entry for operation. For example, if the device inside the cage becomes unbalanced during hoisting, the second door can be used to enter the inside and make fine adjustments to the position.

[0008] In a further embodiment, a plurality of rollers are fixedly installed inside the cage.

[0009] By adopting the above technical solution, when it is necessary to place equipment inside the cage, the first door is opened, and then a trolley that is about the same height as the bottom of the cage is used to push the equipment to the side of the cage, and then the equipment is pushed into the cage.

[0010] In a further embodiment, a tray located at the bottom of the cage is placed on the roller, and the tray is provided with multiple through holes.

[0011] By adopting the above technical solution, the pallet can be placed on the trolley and then pushed into the cage along with the pallet. By inserting detachable locking rods into multiple through holes, the position of the pallet inside the cage is fixed, preventing the pallet from sliding and hitting the cage from the direction of entry. The top of the locking rod is a large-diameter circular plate to prevent the locking rod from falling directly out of the through hole after insertion. The bottom ends of multiple locking rods contact the rollers and cooperate with each other to limit the slippage of the pallet. The reason why the pallet does not slip along the axis of the rollers is that the weight of the equipment installed on it prevents it from sliding. However, the slippage of the pallet along the direction of entry and exit is due to rolling friction, so locking rods are needed to lock it.

[0012] In a further embodiment, chains are fixedly installed at the four bottom corners of the hanging platform, the chains are connected to the corresponding hanging rings below, and a hook is fixedly installed at the top center of the hanging platform.

[0013] By adopting the above technical solution, the chain becomes flexible, thus realizing a flexible connection structure.

[0014] In a further embodiment, a plurality of latches are provided on one side of the cage from top to bottom, and a padlock corresponding to each latch is provided on the cage door.

[0015] By adopting the above technical solution, the problem of equipment falling off due to failure caused by only setting a single latch can be avoided.

[0016] In a further embodiment, both the first door and the second door are steel frame structures.

[0017] In summary, this utility model has the following beneficial effects:

[0018] 1. The first door opens outwards towards the cage to allow the device to be placed more easily inside the cage. The second door opens inwards towards the cage to facilitate access for operation. For example, if the device inside the cage becomes unbalanced during hoisting, the second door can be used to enter and fine-tune its position. Attached Figure Description

It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to the attached figures. Figure 1 In this specification, the terms "bottom surface" and "top surface," "inner" and "outer" refer to the direction toward or away from the geometry of a specific component. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this specification, "a plurality of" means two or more, unless otherwise explicitly and specifically defined by the direction of the center.

[0023] Example 1:

[0024] like Figure 1As shown, a fixed hoisting cage for installing a generator set includes a cage body 1. Hoisting rings 2 are fixedly installed at the four corners of the top of the cage body 1. A flexibly connected hoisting plate 3 is provided at the top of the cage body 1. A cage door 4 is movably installed on the left side of the cage body 1. The cage door 4 includes a frame 41, a first door body 42, and a second door body 43. The first door body 42 is movably installed inside the frame 41. A mounting frame for installing the second door body 43 is provided on the first door body 42. The second door body 43 is movably installed within the mounting frame. The opening and closing direction of the first door body 42 is towards the outside of the cage body 1, and the opening and closing direction of the second door body 43 is towards the inside of the cage body. The first door body opens and closes towards the outside of the cage body to allow for better placement of the device inside the cage. The second door body opens and closes towards the inside of the cage body to facilitate access for operation. For example, if the device inside the cage body becomes unbalanced during hoisting, the second door body can be used to access the inside and fine-tune its position. Multiple rollers are fixedly installed inside the cage body 1. Supports located at the bottom of the cage body 1 are placed on the rollers. The pallet has multiple through holes, allowing it to be placed on a trolley and then pushed into the cage along with the pallet. Removable locking rods inserted into these through holes secure the pallet inside the cage, preventing it from sliding and impacting the cage during entry. The locking rods have a large-diameter disc at the top to prevent them from falling out of the through holes after insertion. The bottom ends of the multiple locking rods contact rollers, working together to restrict pallet slippage. The sliding along the axis of the roller is prevented from sliding by the weight of the equipment installed on it. However, the sliding of the pallet along the in-and-out direction is due to rolling friction, so a locking rod is required to lock it. Chains are fixedly installed at the four corners of the bottom of the hanging plate 3, and the chains are connected to the corresponding lifting rings 2 below. A hook is fixedly installed at the center of the top of the hanging plate 3. Multiple latches are provided on one side of the cage 1 from top to bottom, and padlocks corresponding to the latches are provided on the cage door 4. The first door 42 and the second door 43 are both steel frame structures.

[0025] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
