Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] like Figure 1As shown, in order to achieve the above objectives, this utility model provides an air conditioning unit hoisting fixture, including: a main frame 1, a hoisting rope 4, and a support plate 6.
[0029] The main frame 1 is internally equipped with transverse beams 2 and longitudinal beams 3. The transverse beams 2 and longitudinal beams 3 are intersecting and connected. The transverse beams 2 strengthen the transverse connections of the main frame 1, and the longitudinal beams 3 strengthen the longitudinal connections, thereby enhancing the rigidity and strength of the main frame 1. Specifically, three transverse beams 2 are provided on the inner side of the main frame 1, extending along a first direction, such as... Figure 1 As shown, the first direction is Figure 1 In the X direction, a longitudinal beam 3 is installed on the inner side of the main frame 1. The longitudinal beam 3 extends along a second direction, which is... Figure 1 The second direction is perpendicular to the first direction. Of course, two or more longitudinal beams 3 can also be set according to the dimensions of the main frame 1 in the first direction to further enhance the rigidity and strength of the main frame 1.
[0030] Several lifting ropes 4 are installed on the bottom surface of the main frame 1. Optionally, the lifting ropes 4 are iron chains. Each lifting rope 4 has a hook 5 at its lower end. The hooks 5 installed on the bottom surface of the main frame 1 are directly connected to the top corner of the air conditioning unit. It should be noted that when the hooks 5 are connected to the air conditioning unit, the opening of the hooks 5 faces the inside of the main frame 1 to prevent the hooks from coming off and to ensure the safety of the air conditioning unit during hoisting.
[0031] A support plate 6 is provided at one end of the main frame 1 in the second direction. The support plate 6 extends along the first direction. Several counterweight support columns 7 are arranged in an array on the top surface of the support plate 6 along the first direction. The end of the main frame 1 with the support plate 6 is positioned above the end away from the center of gravity of the air conditioning unit. A counterweight 8 of appropriate weight is arranged on the support plate 6 to keep the main frame 1 in a horizontal state and to keep the force balanced at each position on the horizontal plane. This prevents the air conditioning unit from shaking significantly during hoisting and avoids the phenomenon of the air conditioning unit tilting, effectively ensuring the safety of the air conditioning unit during hoisting.
[0032] It should be noted that the counterweight 8 includes various specifications, and the weight of each specification of counterweight 8 is different. Preferably, the weight of the first counterweight 8 is twice the weight of the second counterweight 8. For example, one specification of counterweight 8 is 10kg and another specification of counterweight 8 is 5kg. Counterweights 8 of different specifications can all be connected to the counterweight support 7.
[0033] In some embodiments of this utility model, a base 9 is provided at the center of the main frame 1. The base 9 and the main frame 1 are located on the same plane. Optionally, the base 9 is rectangular in shape, and the edges between two adjacent sides of the base 9 are connected to one of the transverse beams 2 or one of the longitudinal beams 3. Specifically, the outer periphery of the base 9 has four edges. Two edges that are symmetrical about the center of the base 9 are connected to a longitudinal beam 3, and the other two edges that are symmetrical about the center of the base 9 are connected to a transverse beam 2.
[0034] Furthermore, a fixing column 10 is provided on the top surface of the base 9. Several first diagonal braces 11 are provided on the outer circumferential side of the upper end of the fixing column 10. The several first diagonal braces 11 are respectively connected to the end positions of the top edge of the main frame 1. Specifically, four first diagonal braces 11 are respectively connected to the end positions of the top edge of the main frame 1 to improve the deformation resistance of the main frame 1 in the vertical direction and increase the rated load of the overall air conditioning unit hoisting fixture. In addition, a lifting ring 13 is provided on the top surface of the fixing column 10. Optionally, the lifting ring 13 is threaded to the top surface of the fixing column 10, or it can be directly integrally formed with the fixing column 10. The purpose of providing the lifting ring 13 is to facilitate the connection between the main frame 1 and the hoisting equipment.
[0035] Similarly, several second diagonal braces 12 are set on the outer circumferential side of the middle part of the fixed column 10. The several second diagonal braces 12 are respectively connected to the middle position of the top edge of the main frame 1. Specifically, four first diagonal braces 11 are respectively connected to the middle position of the top edge of the main frame 1, so as to further improve the deformation resistance of the main frame 1 in the vertical direction and improve the rated load of the hoisting tool of the overall air conditioning unit.
[0036] like Figure 2 As shown, in some embodiments of this utility model, a through hole 801 is provided in the middle part of the counterweight 8. The through hole 801 is used to pass through the counterweight support 7 so that the counterweight 8 can be stably fixed on the top surface of the support plate 6. It should be noted that the distance between two adjacent counterweight support 7 is large enough to ensure that the counterweight 8 can be passed through the two adjacent counterweight support 7 at the same time.
[0037] Optionally, the counterweight support 7 can be one or more of a polygonal prism and a cylinder. When the counterweight support 7 is a polygonal prism, the through hole 801 is polygonal; when the counterweight support 7 is a cylinder, the through hole 801 is circular, to ensure a stable fit between the counterweight support 7 and the counterweight 8. It should be noted that the counterweight support 7 and the through hole 801 are clearance-fitted to facilitate the installation and removal of the counterweight 8 from the counterweight support 7. Additionally, two handles 802 are provided on the top surface of the counterweight 8 to assist the operator in assembling and disassembling the counterweight 8 from the counterweight support 7.
[0038] It should be noted that when the positions of the air conditioning unit connected to each hook 5 are on the same horizontal plane, the length of each lifting rope 4 is adjusted to make the distance from several hooks 5 to the bottom surface of the main frame 1 equal. However, when the positions of the air conditioning unit connected to each hook 5 are not on the same horizontal plane, the length of each lifting rope 4 is adjusted according to the position of the air conditioning unit connected to each hook 5. This ensures that the main frame 1 remains horizontal during the hoisting process and that the force at each position on the horizontal plane is balanced, further guaranteeing the safety of the air conditioning unit during the hoisting process.
[0039] like Figure 3 , Figure 4 and Figure 6 As shown, in some embodiments of this utility model, two guide rails 14 are provided at the bottom of the main frame 1. The two guide rails 14 are fixed to the bottom of the main frame 1 by bolt connection or welding. The two ends of the two guide rails 14 are located at two diagonal positions on the main frame 1. It should be noted that the middle parts of the two guide rails 14 are connected together. In addition, a positioning seat 15 is slidably provided in the guide rail 14. Specifically, a positioning groove 1401 is opened along the length direction of the guide rail 14. The positioning seat 15 is slidably connected in the positioning groove 1401. The upper end of the lifting rope 4 is connected to the bottom surface of the positioning seat 15. By moving the four positioning seats 15 synchronously, the position between the four lifting ropes 4 can be adjusted by changing the position of the positioning seats 15 in the length direction of the guide rail 14. Thus, the four hooks 5 can be adjusted according to the size of the air conditioning unit to expand the applicability of the overall air conditioning unit lifting tool and improve its practicality.
[0040] It should be noted that a positioning seat 15 is slidably set at each end of each guide rail 14. The distance from each positioning seat 15 in the two guide rails 14 to the center position of the corresponding guide rail 14 is equal, so as to ensure that the four suspension ropes 4 are always evenly distributed below the main frame 1, so that when the main frame 1 is kept horizontal, the force on each position of the main frame 1 on the horizontal plane remains balanced.
[0041] like Figure 3 and Figure 5As shown, it should be further explained that several first positioning holes are arrayed on both sides of the guide rail 14, and second positioning holes are provided on the side of the positioning seat 15. The axes of the first and second positioning holes are always parallel. After the four positioning seats 15 move to a suitable position along the length of the guide rail 14, positioning bolts 16 pass through the first and second positioning holes. The tail of the positioning bolt 16 is threaded into the first positioning hole, locking the positioning seat 15 onto the guide rail 14. This ensures that the positioning seat 15 will not shift when the overall air conditioning unit hoisting fixture is hoisting the air conditioning unit, keeping the hoisting rope 4 and hook 5 stable. Optionally, a pin hole is provided at the tail of the positioning bolt 16, and a pin 17 is inserted into the pin hole to further prevent the positioning bolt 16 from falling out of the first and second positioning holes, improving the safety when hoisting the air conditioning unit.
[0042] In addition to the aforementioned air conditioning unit hoisting fixture, this utility model also provides a hoisting device that includes the air conditioning unit hoisting fixture disclosed in the above embodiments. For the structure of other parts of the hoisting device, please refer to the prior art, which will not be described in detail here.
[0043] In summary, by arranging counterweights 8 of appropriate weight on the support plate 6, the main frame 1 is kept horizontal and the force is balanced at all positions on the horizontal plane, preventing large-scale shaking of the air conditioning unit during hoisting and avoiding tilting of the air conditioning unit, thus effectively ensuring the safety of the air conditioning unit during hoisting.
[0044] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.
[0045] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of this utility model.
