Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical equipment hoisting, in particular to a vertical hoisting device for large electromechanical equipment in a narrow space of a basement. Background Art

[0002] In public construction projects, we often encounter some large electromechanical equipment that are large in size and heavy, generally weighing about ten tons, such as air-conditioning water-cooled centrifugal chillers, diesel generators, etc., which are usually installed in the basement.

[0003] Combining existing technologies, we found that:

[0004] The traditional installation method is to transport the equipment to the installation location through the basement entrance channel. However, the installation location of many large equipment is often located in the corner of the basement. Using a reserved transportation channel in the basement means that the equipment needs to pass through many basement partition walls, which may even include civil defense walls.

[0005] In this case, transportation and installation work face huge difficulties. First of all, the equipment is huge. In order to ensure that the clearance meets the requirements, the mechanical and electrical pipelines and partition walls on the transportation route need to be reserved. Construction can only be carried out after the equipment is installed. The finishing work cycle of a large number of working surfaces is long and the construction cost is high, which seriously affects the construction progress. Utility Model Content

[0006] In order to solve the above technical problems, the utility model proposes a vertical lifting device for large electromechanical equipment in a narrow space of a basement. The electromechanical equipment is lifted by a car crane, avoiding the tedious transportation of the electromechanical equipment through the reserved transportation channel in the basement. By providing a lifting mechanism, it can be appropriately adjusted according to the length of the electromechanical equipment, and the adaptability is stronger. The adjusted lifting mechanism cooperates with the rope to tighten and bind the electromechanical equipment. Compared with lifting directly by the lifting rope on the car crane, the shaking during the lifting process is reduced.

[0007] The technical solution to achieve the purpose of the utility model is: a vertical lifting device for large electromechanical equipment in a narrow space of a basement, including a car crane, a lifting rope is provided inside the car crane, a hook is installed at one end of the lifting rope, and also includes: a lifting mechanism, the lifting mechanism is arranged at a position below the hook; the lifting mechanism includes a mounting plate arranged at a position below the hook, a fixed block fixed on the inner side of the mounting plate at a middle position, a motor is installed on the outer side of the mounting plate, a bidirectional screw rod is fixed to the output end of the motor and is rotatably extended to the inner side of the mounting plate, the bidirectional screw rod passes through and is rotatably connected to the inner side of the fixed block, and the outer side of the bidirectional screw rod is symmetrically rotatably connected to two moving blocks through threads, two connecting arms are symmetrically fixed to the lower sides of the two moving blocks, and a rope ring is fixed to the lower end of the two connecting arms.

[0008] In some embodiments, two connecting arms 2 are symmetrically fixed to the lower side of the fixing block, and a rope ring 2 is fixed to the lower end of each of the two connecting arms 2.

[0009] In some embodiments, a hanging ring adapted to the hook is fixed to the upper side of the mounting plate.

[0010] In some embodiments, the inner sides of the two rope rings 2 and the plurality of rope rings 1 are all covered with rubber sleeves.

[0011] In some embodiments, two sliding grooves are symmetrically provided on the inner side of the mounting plate, and a slider is slidably provided on the inner side of each of the two sliding grooves, and the two sliders are respectively fixed to the upper sides of the two moving blocks.

[0012] In some embodiments, a mounting bracket is fixed to the outside of the motor, and the mounting bracket is fixed to the mounting plate by multiple sets of screws.

[0013] Compared with the prior art, the present invention has the following significant advantages:

[0014] First, the utility model uses a car crane to lift the electromechanical equipment, avoiding the tedious transportation of the electromechanical equipment through the reserved transportation channel in the basement. The lifting mechanism can be properly adjusted according to the length of the electromechanical equipment, which makes it more adaptable. The adjusted lifting mechanism cooperates with the rope to tighten and tie the electromechanical equipment. Compared with lifting directly with the lifting rope on the car crane, the shaking during the lifting process is reduced.

[0015] Second, the utility model is provided with rubber sleeves on the inner sides of the multiple rope rings 1 and the two rope rings 2, which can reduce the wear between the rope and the two rope rings 2 and the multiple rope rings 1, and further improve the safety performance of the lifting;

[0023] The following is a detailed description of the present invention, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides a vertical lifting device for large electromechanical equipment in a narrow space of a basement through improvement. The technical solution of the utility model is:

[0025] like Figure 1-Figure 3 As shown, a vertical lifting device for large electromechanical equipment in a narrow space of a basement includes a car crane 1, a lifting rope 2 is provided inside the car crane 1, and a hook 3 is installed at one end of the lifting rope 2. The length of the lifting rope 2 is adjusted to move the hook 3 down to the lifting position, and the car crane 1 is used for lifting. The transportation is portable, and the device also includes: a lifting mechanism, which is provided at a position below the hook 3; the lifting mechanism includes a mounting plate 4 provided at a position below the hook 3, a fixing block 7 fixed at the inner side of the mounting plate 4 at a middle position, a motor 5 is installed at the outer side of the mounting plate 4, a bidirectional screw rod 6 is fixed at the output end of the motor 5, and the bidirectional screw rod 6 is rotatably extended to the inner side of the mounting plate 4, the bidirectional screw rod 6 penetrates and is rotatably connected to the inner side of the fixing block 7, and the outer side of the bidirectional screw rod 6 is symmetrically rotatably connected to two moving blocks 8 through a thread, and two connecting arms 9 are symmetrically fixed to the lower sides of the two moving blocks 8, and a rope ring 10 is fixed to the lower end of the two connecting arms 9;

[0026] According to the length of the electromechanical equipment, the spacing between the multiple connecting arms 9 is controlled, the switch of the motor 5 is turned on, the motor 5 drives the bidirectional screw 6 to rotate, and the rotation of the bidirectional screw 6 drives the two moving blocks 8 to move relative to each other through the threaded engagement, and the spacing is adjusted so that the spacing between the multiple rope rings 10 meets the length of the electromechanical equipment. A rope is used to pass through the inner side of the multiple rope rings 10 in turn and bundled with the electromechanical equipment. According to the above principle, the electromechanical equipment is tied, and the binding needs to be tight and firm, which improves the stability during lifting. After the binding is completed, the lifting rope 2 is adjusted to tighten and lift. By tightening the lifting rope 2 and setting the lifting mechanism, compared with direct lifting, the problem of shaking during lifting is reduced, and the overall stability is improved.

[0027] like Figure 3 As shown, in one embodiment, two connecting arms 2 11 are symmetrically fixed to the lower side of the fixed block 7, and the lower ends of the two connecting arms 2 11 are fixed with rope rings 2 12. By passing the rope through the inside of the two rope rings 2 12, it can be tied to the middle section of the electromechanical equipment to improve stability during lifting.

[0028] like Figure 2 As shown, in one embodiment, a hanging ring 13 adapted to the hook 3 is fixed to the upper side of the mounting plate 4 , thereby ensuring the connection between the mounting plate 4 and the hook 3 .

[0029] like Figure 3 As shown, in one embodiment, in order to reduce the wear of the rope during the lifting process, the inner sides of the two rope rings 12 and the multiple rope rings 10 are all provided with rubber sleeves 14 to further improve the safety performance.

[0030] like Figure 3 As shown, in one embodiment, in order to ensure the relative horizontal movement of the two moving blocks 8, two sliding grooves 15 are symmetrically provided on the inner side of the mounting plate 4, and sliders 16 are slidingly provided on the inner sides of the two sliding grooves 15. The two sliders 16 are respectively fixed to the upper sides of the two moving blocks 8 to play a guiding role.

[0031] like Figure 2 and Figure 3 As shown, in one embodiment, a mounting bracket 17 is fixed to the outside of the motor 5 , and the mounting bracket 17 is fixed to the mounting plate 4 by multiple sets of screws, and the motor 5 is installed through the mounting bracket 17 .

[0032] The specific working method is: clean the lifting operation surface, harden the site before construction, combine the on-site mechanical placement, consider factors such as the model of the automobile crane 1 and the lifting rope 2, hook 3, etc., conduct equipment inspection in advance, and when lifting, first transport the large electromechanical equipment to the lifting point, then set up the automobile crane 1 in place as required, and conduct a slow trial lift before lifting to detect whether the ground has sunk or cracked, adjust the length of the rope 2 and move the hook 3 down to the lifting position, and control the spacing between multiple connecting arms 9 according to the length of the electromechanical equipment, turn on the switch of the motor 5, and the motor 5 drives the bidirectional screw 6 to rotate. The rotation of the bidirectional screw 6 drives the two moving blocks 8 to move relative to each other through the thread engagement to adjust the spacing. The spacing between multiple rope rings 10 is made to match the length of the electromechanical equipment. Three ropes are used to pass through the two adjacent rope rings 10 at both ends and the middle end and the inner side of the adjacent rope ring 2 12 in sequence, and then they are bundled with the electromechanical equipment. Through the above principle, the two ends and the middle end of the electromechanical equipment are tied. The binding must be tight and firm, which improves the stability during lifting. After the binding is completed, the hook 3 is hung with the hanging ring 13 on the upper side of the mounting plate 4, and the lifting rope 2 is adjusted to tighten and lift. By tightening the lifting rope 2 and setting the lifting mechanism, compared with direct lifting, the problem of easy shaking during the lifting process is reduced, the overall stability is improved, and the electromechanical equipment is lifted by the automobile crane 1 to solve the problem of inconvenience in transportation.
