Description

Technical Field

[0001] The invention relates to the technical field of hoisting, and in particular to a tool for safely and stably hoisting a dehumidifier compressor. Background Art

[0002] Dehumidifiers, as crucial ventilation equipment in shipbuilding and industrial equipment maintenance, present a high level of technical difficulty in disassembling and repairing their compressors. When a dehumidifier compressor malfunctions, traditional cranes are impractical due to its substantial weight (typically reaching 515 kg) and its unique installation location (located in the center of the dehumidifier, behind the door pillars). Furthermore, the large condenser covering the top of the dehumidifier makes direct lifting impossible. Furthermore, compressor disassembly and installation must be performed within a confined space, placing extremely high demands on the stability, flexibility, and safety of the lifting equipment.

[0003] In the existing technology, the hoisting operation for this type of compressor mainly relies on temporary welding lifting points, manual crowbars to assist in rotation and other solutions. However, such solutions have exposed significant defects in actual application. In traditional solutions, the counterweight device is usually a simple stack of heavy objects, and there is no effective anti-tilt support structure. When hoisting a 515KG compressor, the counterweight block is easily displaced due to inertia during movement or force application, causing the overall center of gravity of the tooling to shift and causing the risk of tilting. For example, during the lifting process of the original solution, due to the large space for the counterweight block to move, there have been many cases of tooling tilting due to counterweight imbalance, and even accidents that almost caused the equipment to fall. The steering mechanism of the mobile frame of traditional tooling mostly adopts a manual push-pull design, which requires multiple people to work together to complete the steering, and it is difficult to accurately control the direction of displacement. Especially in the narrow space inside the dehumidifier, the inflexible steering can cause the compressor to collide with the inner wall of the equipment, damaging the refrigeration system. It is urgent to design a special tooling with anti-tilt support, flexible steering and high-strength structure to solve the above technical pain points. Summary of the Invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0019] Example 1 See also Figure 1-9The present invention provides a tool for safely and stably lifting a dehumidifier compressor, comprising a mobile frame 1, a counterweight box 2 is fixed above the mobile frame 1, a direction control component 3 is provided on one side of the mobile frame 1, and an anti-tilt support mechanism is provided inside the counterweight box 2, the anti-tilt support mechanism comprises a first rotating arm 15, a second rotating arm 16, an anti-tilt limit block 17 and a lifting assembly 18, the first rotating arm 15 and the second rotating arm 16 are both arranged in the inner cavity of the counterweight box 2, the first rotating arm 15 is arranged above the second rotating arm 16, one end of the first rotating arm 15 and the second rotating arm 16 is provided with an anti-tilt limit block 17, and the other end of the first rotating arm 15 and the second rotating arm 16 is provided with a lifting assembly 18; in the preparation stage of the lifting operation, first, a counterweight of appropriate weight is placed in the counterweight chamber 13 of the counterweight box 2, the operator holds the adjusting knob 28 and rotates it clockwise or counterclockwise, at this time the adjusting screw 25 will be supported by the rotating bearing 26 on the counterweight The two lifting blocks 19 are symmetrically distributed on the two sections of the spiral pattern, and when the screw rotates, the two lifting blocks 19 will move closer to or away from each other along the lifting grooves 27 on the inner wall of the counterweight box 2 according to the direction of rotation. As the lifting blocks 19 move, the connected rotating support 20 drives the first rotating arm 15 and the second rotating arm 16 to move synchronously. When the two lifting blocks 19 approach each other, the first rotating arm 15 and the second rotating arm 16 are folded toward each other with one end hinged on the anti-slip shaft 24 as a fulcrum until the anti-slip pads 34 at the end are tightly fitted to the surface of the counterweight. The two sets of anti-slip pads 34 apply pressure from both sides to form a firm clamp, so that the counterweight remains upright in the counterweight box 2, which not only makes full use of the internal space, but also effectively avoids the risk of tilting caused by shaking and displacement of the counterweight during lifting, and provides reliable stability for the lifting operation.

[0020] It is worth mentioning that an anti-slip shaft 24 is fixed between the inner walls of the anti-tilt limit block 17, one end of the first rotating arm 15 and the second rotating arm 16 are both rotatably connected to the anti-slip shaft 24, and an anti-slip pad 34 is fixed to one end of the anti-tilt limit block 17.

[0021] It is worth mentioning that the lifting assembly 18 includes a lifting slider 19 and a rotating support 20. The rotating support 20 is rotatably connected to the other end of the first rotating arm 15 and the second rotating arm 16. The lifting slider 19 is fixed on a side surface of the rotating support 20.

[0022] It is worth mentioning that a lifting slot 27 is provided on the inner side wall of the counterweight box 2 , and the two lifting sliders 19 are slidably connected in the lifting slot 27 of the counterweight box 2 .

[0023] It is worth mentioning that a thread groove 21 is provided on one end face of the lifting slider 19 , and an adjusting screw 25 is rotatably connected inside the counterweight box 2 , and the adjusting screw 25 is threadedly connected to the thread groove 21 of the lifting slider 19 .

[0024] It is worth noting that a rotating bearing 26 is fixed to the inner bottom wall of the counterweight box 2 , one end of the adjusting screw 25 extends into the rotating bearing 26 , and an adjusting knob 28 is fixed to the end of the adjusting screw 25 away from the rotating bearing 26 .

[0025] It is worth mentioning that an embedding groove 29 is opened on the inner wall of the counterweight box 2, and the rotating bearing 26 is embedded and fixed in the embedding groove 29 of the counterweight box 2. An adjustment port 30 is opened on the inner wall of one side of the counterweight box 2, and the adjustment knob 28 is rotatably connected to the adjustment port 30 of the counterweight box 2.

[0026] It is worth mentioning that a non-slip pad 34 is fixed to one end of the anti-tilt limit block 17, bidirectional spiral patterns are symmetrically arranged on the surface of the adjusting screw 25, two lifting sliders 19 are symmetrically distributed on the two sections of the spiral patterns of the adjusting screw 25, a counterweight chamber 13 is provided inside the counterweight box 2, a rotating opening 22 is provided on one side surface of the rotating support 20, and a protruding rotating shaft 23 is fixed to one end face of the first rotating arm 15, and the protruding rotating shaft 23 is rotationally matched with the rotating opening 22 of the rotating support 20.

[0027] This solution has the following working process: before hoisting, first place the counterweight block in the counterweight box 2, then rotate the adjusting knob 28 to drive the adjusting screw 25 to rotate at the rotating bearing 26 on the bottom wall of the counterweight box 2. Since the two lifting sliders 19 are symmetrically arranged on the adjusting screw 25, the adjusting screw 25 can be rotated to move the two lifting sliders 19 closer to or farther away from each other, so that the distance between the two lifting sliders 19 can be adjusted. At this time, the first rotating arm 15 is hinged on the rotating support 20 of one lifting slider 19, and the second rotating arm 16 is hinged on the rotating support 20 of the lifting slider 19. It is connected to the rotating support 20 of the other lifting slider 19, so that when the two lifting sliders 19 are close to each other, the first rotating arm 15 and the second rotating arm 16 can be continuously folded toward each other, so that the anti-slip pads 34 at one end of the first rotating arm 15 and the second rotating arm 16 are close to the counterweight block. The two sets of anti-slip pads 34 run towards each other to stably clamp the counterweight block in the counterweight box 2, thereby facilitating the upright placement of the counterweight block during the use of the counterweight, and adapting to the placement space of the counterweight box 2, reducing the trouble of the counterweight block being displaced and causing tilting due to the existence of activity space during the lifting process.
