Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning equipment, in particular to a modular machine unit frame structure. Background Art

[0002] As people's requirements for quality of life improve, air conditioners have become an indispensable and important electrical appliance in people's lives. In the production and manufacturing process of air conditioner components, after the production of the condenser components is completed, in order to ensure the production efficiency of the assembly line operation, the condenser components are hoisted and placed on the frame structure of the modular unit, and need to be assembled and fixed with the frame structure of the modular unit.

[0003] like Figure 7 As shown, the existing modular machine unit frame structure is composed of four columns, beams connecting the columns and a base plate assembly. The beams in the structure are fixed to the four columns by bolts. The condenser assembly is placed on the middle circle beams from top to bottom from the upper ends of the four columns and is connected to the beams by bolts. At this time, the middle circle beams bear the weight of the entire condenser, so that the bolts connecting the beams and the columns bear the shear force in the vertical direction of the modular machine unit frame. During transportation, there is a risk that the bolts connecting the beams and the columns will break due to the shear force, causing the modular machine unit frame structure to collapse and fall. In addition, in order to limit the four sides of the condenser assembly to prevent the condenser assembly from swaying during transportation, the column part at the upper end of the middle circle beams is set at a height higher than the vertical height of the condenser assembly. This makes the hoisting height too high when the condenser assembly is hoisted to the middle circle beams, which poses a certain safety risk. Utility Model Content

[0004] In order to solve the technical problem of the safety risk that the bolts connecting the cross beams and the columns of the existing modular machine unit frame structure are prone to breakage due to long-term shear force, the utility model provides a modular machine unit frame structure.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The frame structure of the module machine unit includes a base plate assembly, columns, beams a and beams b. The columns include inner columns and outer columns. The inner columns are vertically fixed on the base plate assembly. The beams a and beams b are horizontally placed on the upper end surfaces of the inner columns and fixedly connected to form the main body of the template machine unit frame structure. The outer columns are vertically arranged and fixedly connected to the inner columns.

[0007] Furthermore, the outer column and the inner column are detachably connected.

[0008] Furthermore, the cross-section of the inner column is V-shaped, and angle seats are provided at the upper and lower ends of the inner column, the angle seats are provided with mounting holes, and both side edges of the upper and lower ends of the inner column are also provided with mounting holes.

[0009] Furthermore, the crossbeam a is a square tube, a side portion of the crossbeam a is provided with an opening, and the opening faces the crossbeam b, a mounting hole is provided on the side where the crossbeam a cooperates with the inner column and is connected by bolts, and a mounting hole is provided on the side where the crossbeam a cooperates with the outer column and is connected by bolts.

[0010] Furthermore, a mounting hole is provided on the side of the cross beam a for mounting the condenser assembly, and notches are provided at both ends of the side at positions corresponding to the mounting holes connected to the inner columns.

[0011] Furthermore, an opening is provided on the side of the outer column toward the condenser assembly, and the opening extends from the top end of the outer column to the bottom end of the outer column. Both sides of the outer column opening are in contact with the base plate assembly, the inner column, the beam a and the beam b, and are fixedly connected by bolts.

[0012] Furthermore, the cross beam b is connected to the inner column by bolts, and a mounting hole is provided on the side where the cross beam b cooperates with the outer column.

[0013] Furthermore, the thickness of the cross beam a and the cross beam b is set to 2.5 mm.

[0014] The beneficial effect of the utility model is as follows: by setting the columns as inner columns and outer columns, and placing beams a and b horizontally on the upper end surface of the inner columns and fixedly connected, and then fixing the outer columns on the inner columns, the design makes it possible for the bolts connecting the load-bearing beams a and the inner columns to not be subjected to shear force, thereby avoiding the risk of bolt breakage caused by the bolts connecting the beams a and the inner columns being subjected to high shear force for a long time, and the collapse and fall of the modular machine unit frame structure. When the outer columns and the inner columns are detachably connected, the condenser assembly is first installed on the beam a and then the outer columns are installed, thus solving the safety hazard caused by the high hoisting height. In addition, the inner column is designed to have a V-shaped cross section, the beams a and the beams b are designed to be square tubes, the outer column is open, and the thickness of the beams a and the beams b is 2.5 mm, which not only ensures the strength of the modular machine unit frame structure, but also reduces the material cost and the overall weight of the modular machine unit frame.

[0023] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clearly expressed, the present invention is further described below in conjunction with the accompanying drawings.

[0024] First of all, it needs to be stated that the technical solutions of the embodiments of the present application are clearly and completely described. The described embodiments are part of the embodiments of the present application, rather than limitations of the present utility model. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present application.

[0025] In the description of the present invention, it is necessary to understand that the orientation or position relationship indicated by the terms "up", "down", "left", "right", "inside", "outside", "axial" or "radial" is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention, and is not intended to indicate or imply that the device or element referred to must have a specific orientation structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0026] like Figures 1 to 4As shown, in the embodiment of the utility model, the frame structure of the module machine unit includes a base plate assembly 1, columns, beams a3 and beams b4, the columns include inner columns 2 and outer columns 5, the inner columns 2 are vertically fixedly installed on the base plate assembly 1, the beams a3 and beams b4 are horizontally placed on the upper end surface of the inner columns 2 and fixedly connected to form the main body of the frame structure of the template machine unit, and the outer columns 5 are vertically arranged and fixedly connected to the inner columns 2. In the embodiment of this scheme, four inner columns 2 are installed on the four corners of the base plate assembly 1, and are fixed by bolts or welding, and then two beams a3 and two beams b4 are horizontally placed on the upper end surface of the inner columns 2, and are fixed by bolts or welding. At this time, the screws connecting the beams a3 and the inner columns are vertically arranged, which only provide pre-tightening force and are not subject to shear force in the vertical direction. When the outer column 5 is detachably connected to the inner column 2, the condenser assembly 6 is hoisted to the cross beam a3 on the inner column 2 and fixedly connected to the cross beam a3. At this time, the hoisting height of the condenser assembly 6 is only the height of the inner column 2. Compared with the original technology, it needs to be hoisted to the upper end of the outer column 5 and then placed. On the one hand, during the placement process, the condenser assembly 6 hits the outer column 5 and is scratched and damaged. On the other hand, the hoisting height is too high, which has requirements for the height of the factory building, and there are safety risks if the hoisting is too high. The outer column 5 is vertically installed on the outside of the inner column 2, relying on the lower part of the outer column 5 to be connected with the inner column 2 and the cross beams a3 and b4, the upper part of the outer column 5 is kept stable, and the condenser assembly 6 is limited and protected to prevent the condenser assembly 6 from tilting and shaking.

[0027] like Figures 2 to 4 As shown, in an embodiment of the utility model, the cross-section of the inner column 2 is set to be V-shaped, and the V-shaped opening angle can be a 90-degree right angle, or an acute angle or an obtuse angle, to ensure that the inner column 2 can be vertically installed on the base plate assembly 1 and to ensure the strength of the module machine frame structure. At the same time, the upper and lower ends of the inner column 2 are provided with angle seats 21, and the angle seats 21 are provided with mounting holes for supporting and connecting the cross beams a3 and the cross beams b4, as well as connecting the base plate assembly 1. The upper and lower ends of the inner column 2 are also provided with mounting holes on both sides for connecting with the outer column 5 by bolts.

[0028] like Figure 2 , Figure 3 and Figure 5As shown, in the embodiment of the utility model, the cross beam a3 is a square tube, and an opening 32 is provided on one side of the cross beam a3, and the opening 32 faces the cross beam b4. The side of the cross beam a3 that matches the inner column 2 is provided with a mounting hole, and is connected by bolts. The side of the cross beam a3 that matches the outer column 5 is provided with a mounting hole, and is connected by bolts. The cross beam a3 is a square tube. In order to facilitate the installation of the bolts, an opening 32 is provided on one side of the cross beam a3. In order to ensure a certain strength of the cross beam a3, a part of the side is retained, so that the cross section of the cross beam a3 is G-shaped. This design is to avoid the cross beam a3 being a square tube, and when the opening 32 is not provided, when the bolt is installed, the bolt hole can only be set through the two corresponding surfaces, so that there is interference between the bolts in the square tube, which affects the installation. The cross beam a3 with the opening 32 can reduce the weight while maintaining the strength, thereby saving costs. A mounting hole is provided on the side of the cross beam a3 for mounting the condenser assembly 6, and notches 31 are provided at both ends of the side at positions corresponding to the mounting holes connected to the inner column 2 for placing bolts connecting the cross beam a3 to the inner column 2.

[0029] like Figure 1 , Figure 3 and Figure 6 As shown, in the embodiment of the utility model, the cross beam b4 is connected to the inner column 2 by bolts, and a mounting hole is provided on the side where the cross beam b4 cooperates with the outer column 5. The outer column 5 is provided with an opening on the side facing the condenser assembly 6, and the opening extends from the top of the outer column 5 to the bottom of the outer column 5. The two sides of the opening of the outer column 5 are in contact with the bottom plate assembly 1, the inner column 2, the cross beam a3 and the cross beam b4, and are fixedly connected by bolts. In addition, the opening at the upper end of the outer column 5 accommodates the condenser assembly 6, and performs a limiting guide and support function on the condenser assembly 6. In order to ensure that the cross beam a3 will not bend or break under the influence of force in the process of supporting the condenser assembly 6, the thickness of the cross beam a3 and the cross beam b4 is set to 2.5mm to ensure the strength of the cross beam a3 and the cross beam b4.
