It should be noted that similar reference numerals and letters in the following drawings denote similar items, and therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0055] Example 1:

[0056] like Figures 1-4 As shown, this embodiment provides a lifting frame for air conditioning engineering, including:

[0057] Base frame 1;

[0058] Support platform 2, located above base frame 1, is used to support maintenance personnel for high-altitude operations;

[0059] The lifting mechanism 6 is mounted on the base frame 1 and works in conjunction with the support platform 2 to adjust the height of the support platform 2;

[0060] The platform width adjustment mechanism 3 is installed on the support platform 2 and is used to adjust the width of the support platform 2;

[0061] The platform width adjusting mechanism 3 comprises:

[0062] A storage groove 31 is arranged on the support platform 2, and the storage groove 31 is shared by two;

[0063] A fixed guide rail 32 is arranged on the inside of the two sides of the storage groove 31;

[0064] A support plate 33 is slidingly arranged in the storage groove 31 of the support platform 2, and is used to extend the width of the support platform 2;

[0065] A first sliding rail 34 is arranged on the bottom of the two sides of the support plate 33;

[0066] A second sliding rail 35 is slidingly arranged on the fixed guide rail 32, and the first sliding rail 34 and the second sliding rail 35 are slidingly connected;

[0067] A mounting seat 36 is arranged on the support plate 33;

[0068] A push handle 37 is rotatably arranged on the mounting seat 36.

[0069] In this technical solution, the base frame 1 provides support for the lifting frame 64, ensuring the stability of the entire structure. The support platform 2 is located above the base frame 1 and is the key part of the lifting frame 64, providing a place for maintenance personnel to stand or work. The platform can bear the weight of the workers and can adjust the height to meet the needs of different height operations. The lifting mechanism 6 allows the height of the support platform 2 to be adjusted as needed. Through the lifting mechanism, the support platform 2 can quickly and accurately lift to the desired height, ensuring that workers can easily reach the target area. The platform width adjustment mechanism 3 adjusts the width of the support platform 2 to meet different space requirements. For example, some maintenance or installation tasks require a wider platform, while others can improve flexibility by reducing the platform width. The storage slot 31 is set on both sides of the support platform 2 and is responsible for accommodating the sliding components required for width adjustment. The storage slot 31 allows the platform width to be adjusted by providing space for the sliding of the support plate 33. The fixed guide rail 32 is installed inside the storage slot 31 on both sides, ensuring that the support plate 33 can slide smoothly and accurately within the slot, preventing any deviation or instability of the platform. The support plate 33 is the main component of the platform width adjustment and can slide within the storage slot 31. The support plate 33 extends or shrinks the width of the platform to meet different operation requirements; the support plate 33 ensures its stability during sliding and does not loosen or slip. The first sliding rail 34 and the second sliding rail 35 are respectively set on both sides of the bottom of the support plate 33 and the fixed guide rail 32, ensuring that the support plate 33 can slide smoothly on the platform. The cooperation of the first sliding rail 34 and the second sliding rail 35 allows the support plate 33 to adjust the width of the support plate 33 flexibly and maintain stability during work. The push handle 37 is designed to be rotatable, allowing maintenance personnel to easily pull out the support plate 33 to the appropriate width when standing on the platform. The mounting seat 36 fixes the position of the push handle 37, making it less likely to loosen or be damaged.

[0070] Work flow: If the width of the platform needs to be adjusted, the maintenance personnel first rotate the handle 37, and rotate the handle 37 from the support plate 33 to the vertical state in order to use the handle 37. Then use the handle 37 to push the support plate 33 to slide, make the support plate 33 slide in the storage groove 31, the support plate 33 drives the first slide rail 34 and the second slide rail 35 to slide outward along the fixed guide rail 32, after the second slide rail 35 slides to the limit position along the fixed guide rail 32, the first slide rail 34 slides outward along the second slide rail 35, the sliding of the support plate 33 is carried out through the cooperation of the first slide rail 34 and the second slide rail 35, which ensures smooth adjustment, when the support plate 33 moves outward to the appropriate width, the maintenance personnel stop pulling the handle 37; At this time, the support plate 33 is extended outward to the appropriate position to increase the width of the support platform 2. Then, the maintenance personnel stand on the support platform 2, and the maintenance personnel adjust the support platform 2 to the appropriate height using the lifting mechanism 6 according to the work requirements, so that the platform can be stably stopped at the required height. After adjusting the height and width of the platform, the maintenance personnel can install, maintain or other related work on the platform; The platform design ensures that the workers can safely and comfortably complete the task at a higher position. After the work is completed, the maintenance personnel can lower the platform to the ground through the lifting mechanism 6, which is convenient for personnel to evacuate and equipment to be retrieved and stored. Then, the maintenance personnel push the handle 37, and the handle 37 pushes the support plate 33 back into the storage groove 31, and the support plate 33 drives the first slide rail 34 and the second slide rail 35 to slide inward along the fixed guide rail 32, when the second slide rail 35 slides to the final position along the fixed guide rail 32, the first slide rail 34 slides inward along the second slide rail 35, so as to store the support plate 33 into the storage groove 31, save space, the air conditioner engineering lifting frame 64 can greatly improve the flexibility and safety of air conditioner installation and maintenance through the design of adjustable height and width, ensure the convenience and stability of operation, so that the lifting frame 64 can adapt to the work requirements in different environments.

[0071] As Figures 1-4 shown, in the present embodiment, the storage groove 31 side wall of the support platform 2 is provided with a guide groove 4, and the front side of the support plate 33 is provided with a guide block 5, and the guide block 5 and the guide groove 4 are slidably connected.

[0072] In the technical scheme, the guide groove 4 is arranged on the side wall of the storage groove 31 of the support platform 2, and the guide block 5 is arranged on the front side of the support plate 33, so that the support plate 33 can slide along the guide groove 4 when the width is adjusted, and the jamming phenomenon caused by uneven sliding or inconsistent direction of the support plate 33 is avoided. The cooperation of the guide groove 4 and the guide block 5 can ensure that the support plate 33 remains stable during the width adjustment process and does not tilt or deviate, ensuring that the entire width adjustment mechanism is more firm and reliable. The design of the guide groove 4 and the guide block 5 helps to reduce the direct friction between the support plate 33 and the storage groove 31, thereby reducing the degree of equipment wear and prolonging the service life of the lifting frame 64. Through the cooperation of the guide block 5 and the guide groove 4, the sliding of the support plate 33 becomes smoother and more stable, and the operator can operate more easily and comfortably when adjusting the width of the platform, improving work efficiency.

[0073] Embodiment 2:

[0074] The embodiment provides a lifting frame for air conditioning engineering, in addition to the technical scheme of the above-mentioned embodiment, further having the following technical features.

[0075] As shown in Figure 1 , Figure 5 and Figure 6 , in the embodiment, the optimized lifting mechanism 6 comprises:

[0076] The sliding groove 61 is arranged on the left and right sides inside the chassis 1.

[0077] The sliding block 62 is slidingly arranged on both sides of the sliding groove 61.

[0078] The connecting rod 63 is arranged between the two sliding blocks 62 on the same side.

[0079] The lifting frame 64 is arranged between the two connecting rods 63, and there are two lifting frames 64, respectively arranged at the two ends of the connecting rod 63.

[0080] The pull block 65 is arranged on the connecting rod 63.

[0081] The bidirectional screw rod 66 is rotatably arranged on the chassis 1, and the pull block 65 is threadedly connected with the bidirectional screw rod 66.

[0082] The handle 67 is arranged at the front end of the bidirectional screw rod 66.

[0083] The fixed frame 68 is located above the chassis 1.

[0084] The recess 69 is arranged on the inner wall of the fixed frame 68.

[0085] The connecting shaft 610 is arranged between the two lifting frames 64, and there are two connecting shafts 610, which are symmetrically distributed.

[0086] Pulleys 611 are arranged at both ends of the connecting shaft 610, and are located inside the grooves 69 and are in sliding connection with the grooves 69. When the lifting frame 64 rotates, the pulleys 611 slide along the grooves 69 and lift the fixed frame 68.

[0087] In the technical solution, when the height of the support platform 2 needs to be adjusted, the operator rotates the handle 67 to drive the bidirectional screw rod 66 to rotate, the rotation of the screw rod drives the pulling block 65 to move along the axial direction of the bidirectional screw rod 66, and the movement of the pulling block 65 drives the displacement of the connecting rod 63 and the sliding block 62. Since the sliding block 62 is located in the sliding groove 61, the movement of the sliding block 62 is limited in the track of the sliding groove 61, so that the movement of the lifting frame 64 cannot deviate or be stuck. The connecting rod 63 is connected to the lifting frame 64, so that the lifting frame 64 is raised along with the change of the connecting rod 63; during the raising of the lifting frame 64, the pulleys 611 on the lifting frame 64 come into contact with the grooves 69 in the inner wall of the fixed frame 68 and slide along the grooves 69. When the lifting frame 64 rotates, the pulleys 611 slide along the inner wall of the grooves 69 and lift the fixed frame 68, the fixed frame 68 drives the support platform 2 to be raised, and when the desired height is reached, the operator stops rotating the handle 67, and the bidirectional screw rod 66 stops rotating. At this time, the lifting frame 64 and the support platform 2 stop raising and lowering, and the air conditioning equipment can be installed or maintained as needed. In this way, the lifting frame 64 can accurately control the raising and lowering of the support platform 2, the operation is more accurate, and the lifting frame 64 is prevented from being out of control or unstable due to improper operation. Efficient installation and maintenance of the air conditioning equipment are realized, and the safety and convenience of the operation are improved.

[0088] Embodiment 3:

[0089] The embodiment provides a lifting frame for air conditioning engineering, in addition to the technical solutions of the above-mentioned embodiments, further having the following technical features.

[0090] As shown in Figure 1 and Figure 5 In the embodiment, the fixed frame 68 and the support platform 2 are connected through a position adjusting mechanism 7, and the position adjusting mechanism 7 comprises:

[0091] Guide rods 71 are arranged at both ends of the upper side of the fixed frame 68;

[0092] Ball screws 72 are rotatably arranged on the upper side of the fixed frame 68;

[0093] Connecting blocks 73 are slidably arranged between the two guide rods 71, the connecting blocks 73 are in threaded connection with the ball screws 72, and the connecting blocks 73 are fixedly connected with the support platform 2;

[0094] Handles 74 are arranged on the ball screws 72.

[0095] In the technical solution, the position adjusting mechanism 7 is designed to allow the support platform 2 to be accurately adjusted in the horizontal direction, ensuring that the platform can meet the needs in different operating environments. By controlling the rotation of the ball screw 72 through the handle 74, the operator can easily adjust the position of the support platform 2 without exerting excessive force, reducing the burden of manual operation. The guide rod 71 works together with the ball screw 72 to ensure that the connecting block 73 maintains a stable trajectory during sliding, thereby avoiding any deviation or instability of the platform. Through the precise adjusting mechanism, the support platform 2 can be firmly fixed at the desired position, preventing vibration or deviation during air conditioning equipment installation, and improving job safety.

[0096] Workflow: When the air conditioning engineering lifting frame 64 is in the initial state, the support platform 2 is connected to the fixed frame 68 through the position adjusting mechanism 7. At this time, the support platform 2 is in a certain preset position and has not been adjusted. When the horizontal position of the support platform 2 needs to be adjusted, the operator starts to rotate the handle 74 on the ball screw 72, which drives the connecting block 73 to slide between the two guide rods 71. Since the connecting block 73 is connected to the ball screw 72 through threads, the rotation of the ball screw 72 can produce precise linear motion, smoothly pushing the connecting block 73 to slide along the guide rod 71. As the connecting block 73 slides, the support platform 2 moves accordingly. At this time, due to the guiding action of the guide rod 71, the sliding path of the connecting block 73 is stably constrained, ensuring that the movement of the support platform 2 is smooth and accurate. When the support platform 2 reaches the desired horizontal position, the operator stops rotating the ball screw 72, and the connecting block 73 stops sliding, and the support platform 2 is stably fixed at the new position. After adjusting the horizontal position of the support platform 2, the platform remains stable at the new position and does not deviate or loosen. The operator can perform air conditioning equipment installation or maintenance work, and the precise positioning of the platform ensures the stability and safety of the equipment installation. If further adjustment is needed, the operator can continue to rotate the handle 74, and the ball screw 72 drives the connecting block 73 to slide again, thereby adjusting the support platform 2 to the desired position, repeating the above operation process. In this way, the support platform 2 can be easily adjusted to the desired position, ensuring accurate docking during air conditioning equipment installation and improving the stability and safety of the operation.

[0097] Embodiment 4:

[0098] The embodiment provides an air conditioning engineering lifting frame, which has the following technical features in addition to the technical solutions of the above embodiments.

[0099] As shown in Figure 1 and Figure 5 In this embodiment, the bottom frame 1 is provided with wheels 8 around the bottom.

[0100] In this technical solution, the wheels 8 enable the chassis 1 to freely slide on the ground, facilitating the operator to quickly move the lifting frame 64 to different working positions. This is particularly important for situations where the height or position of the installed air conditioner needs to be adjusted. Through the wheels 8, the lifting frame 64 can be conveniently moved from one location to another, avoiding the heavy lifting and positioning work, especially in large air conditioner installation or maintenance projects, which can greatly improve work efficiency. By providing wheels 8, the lifting frame 64 is no longer a fixed-position device, and the operator can easily adjust the position of the lifting frame 64 as needed, whether it is to adjust the installation angle or to switch to a different working area, making movement more flexible.

[0101] Embodiment 5:

[0102] This embodiment provides a lifting frame for air conditioning engineering, in addition to the technical solutions of the above embodiments, it also has the following technical features.

[0103] As shown in Figure 1 and Figure 2 In this embodiment, the optimized support platform 2 side is provided with a fence 9, and the fence 9 is provided with a placing shell 10 for placing maintenance tools.

[0104] In this technical solution, the design of the fence 9 can effectively prevent tools, accessories or articles from accidentally falling during operation, especially during high-altitude work, the fence 9 can effectively protect the surrounding environment and personnel safety. The placing shell 10 is designed specifically for storing maintenance tools, which can help the operator to place commonly used tools in a convenient location, avoiding scattered tools and improving work efficiency. It can accommodate various tools such as screwdrivers, wrenches, pliers, etc., ensuring that tools are always available and convenient to operate. By placing tools neatly in the placing shell 10 on the fence 9, the operator does not need to go down frequently to find tools, saving a lot of time and making the air conditioning engineering work more efficient. The tool placing shell 10 helps to organize tools, avoiding scattered tools on the platform or on the ground, keeping the working environment clean. This not only helps to improve work efficiency, but also reduces safety hazards in work. When installing and maintaining air conditioning equipment, the operator often needs to use multiple tools, and through the design of the placing shell 10, tools can be easily accessed during high-altitude work, reducing the need for frequent up and down work and reducing the difficulty of operation.
