[0051] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Components of the embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a variety of different configurations.

[0052] Therefore, the detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0053] It should be noted that like reference numerals and letters denote like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

[0054] In the above description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "one side", "the other side", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is customarily placed during use. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present invention. In addition, terms such as "first", "second", etc. are only used for descriptive distinction and should not be construed as indicating or implying relative importance.

[0055] In addition, terms such as "identical" do not mean that the components are absolutely identical, but there may be slight differences. The term "perpendicular" merely means that the positional relationship between components is more perpendicular relative to "parallel", and does not mean that the structure must be completely perpendicular, but may be slightly inclined.

[0056] Please refer to Figures 1-3, the present invention provides a technical solution: a maintenance and repair device for mechanical equipment, including a base 1. A plurality of universal wheels 11 for moving are installed at the bottom of the base 1 in a corresponding manner. A liquid storage tank 12 is opened on the upper surface of the base 1. Supported by the universal wheels 11, the whole device can be pushed to move. With the self-locking of the universal wheels 11, the position of the device can be fixed after moving to the working area to avoid moving during the operation. Further, in the daily maintenance of mechanical equipment, the parts of the mechanical equipment can be flushed by an external cleaning device, and the cleaning liquid drips along the parts into the opened liquid storage tank 12 for collection. After recycling, it can be used again to improve the utilization rate. Furthermore, when repairing mechanical equipment, after fixing the parts at the positioning mechanism 7, the liquid inside the parts can be directly discharged into the lower liquid storage tank 12, such as the engine oil inside the engine or the lubricating oil inside other equipment, to avoid polluting the working area.

[0057] An embodiment of the support mechanism 2 is as follows: Refer to Figure 3 With Figure 4 , support mechanisms 2 are respectively arranged on both sides of the base 1. A transmission box 22 is arranged on one side of the support mechanism 2. The support mechanism 2 includes an expansion box 21, and one end of the expansion box 21 is internally communicated with the transmission box 22. A driving sprocket and two driven sprockets are respectively arranged in the transmission box 22, and the driving sprocket is located between the two driven sprockets. A motor 23 is fixedly installed on the side wall of the transmission box 22. The output shaft of the motor 23 extends into the transmission box 22 and is coaxially connected with the driving sprocket through a coupling. It should be noted that when the motor 23 is started to operate by the controller 31, the output shaft of the motor 23 will drive the driving sprocket to rotate, and under the transmission connection of the chain, drive the two driven sprockets to rotate synchronously.

[0058] Specifically, a sunk groove is formed in the extension box 21, and a lead screw 24 is installed in the sunk groove. One end of the lead screw 24 is rotatably connected to the inner wall of the extension box 21, and the other end of the lead screw 24 is fixedly connected to a transmission rod 26. The end of the transmission rod 26 away from the lead screw 24 extends into the transmission box 22 and is coaxially connected to a corresponding driven sprocket. A lead screw nut 25 is threadedly connected to the lead screw 24. A limiting block 27 is fixedly connected to the lead screw nut 25, and the width of the limiting block 27 is equal to the width of the sunk groove formed in the extension box 21. The upper surface of the limiting block 27 is rotatably connected to a support rod 28 through a clamping groove. The top of the support rod 28 is rotatably connected to a connecting seat 29. It should be noted that by rotating the driven sprockets on both sides and the transmission rod 26 respectively, the lead screws 24 at the corresponding positions are driven to rotate. Since the bottom of the limiting block 27 is arranged in the sunk groove formed in the extension box 21 and the side wall of the limiting block 27 is in contact with the inner wall of the sunk groove, the rotation of the lead screw nut 25 is restricted. Through the guiding action of the limiting block 27, the lead screw nut 25 will move along the direction of the lead screw 24, thereby driving the position of the bottom of the support rod 28 to be adjusted.

[0059] Referring to Figure 3 , a workbench 3 is installed at the upper end of the base 1 through a hydraulic cylinder 13. A controller 31 is installed on the upper end of the workbench 3, and the controller 31 is electrically connected to the signal line of the hydraulic cylinder 13 and the motor 23 respectively. A placement tray 32 is arranged on the upper surface of the workbench 3, and a plurality of partitions for separation are arranged on the placement tray 32. It should be noted that by starting the hydraulic cylinder 13 to operate through the controller 31 and cooperating with the adjustment of the support rod 28, the upper workbench 3 can be driven to rise and fall, facilitating the maintenance and repair operations of the operator. And during the operation, the parts or tools related to the mechanical equipment can be placed in the placement tray 32 arranged on the workbench 3 and placed neatly in partitions, which is convenient for the operator to take and improves the work efficiency.

[0060] In the above technical solution, an embodiment of the connection mechanism 4 is as follows:

[0061] Referring to Figure 3, a connecting mechanism 4 is arranged on one side of the workbench 3. The connecting mechanism 4 includes two connecting rods 41, and reinforcing ribs are respectively fixedly connected to the bottoms of the two connecting rods 41. Fixed blocks 42 are respectively fixedly connected to the opposite side walls of the two connecting rods 41. The fixed blocks 42 are cylinders. The ends of the two connecting rods 41 away from the workbench 3 are jointly connected to a vertical plate 43. A matching groove 44 is opened at the top of the vertical plate 43, and the width of the matching groove 44 is greater than the width of the storage plate 5. It should be noted that through the support of the two side connecting rods 41 and the reinforcing ribs, the stable connection between the workbench 3 and the vertical plate 43 is ensured, and the loosening of the connection between the vertical plate 43 and the workbench 3 caused by excessive load on the assembly plate 6 on one side of the vertical plate 43 is avoided. Further, the fixed blocks 42 fixedly connected to the side walls of the connecting rods 41 are arranged in the sliding grooves 52 opened on the storage plate 5. Through the limiting action of the two side fixed blocks 42, the storage plate 5 can move up and down. Continuously lift the storage plate 5 upward. When the fixed block 42 moves to the end of the sliding groove 52, cooperating with the arc-shaped side wall arranged at the end of the sliding groove 52, the storage plate 5 can be flipped with the fixed block 42 as the axis. Cooperating with the matching groove 44 opened at the top of the vertical plate 43, finally the storage plate 5 can be laid flat above the assembly plate 6 for the operator to stand on, facilitating the maintenance and repair of high-altitude mechanical equipment. The provided convex plate 51 can mark the edge position of the storage plate 5, improving the safety of the operator during maintenance and repair.

[0062] Refer to Figure 5 and Figure 6 , a storage plate 5 is arranged between the workbench 3 and the connecting mechanism 4. A plurality of convex plates 51 are arranged on the surface of the storage plate 5 close to the workbench 3. Sliding grooves 52 are respectively opened on both sides of the storage plate 5. A bracket 53 is fixedly connected to the other side of the storage plate 5. A bit holder 54 is installed below the bracket 53. A plurality of socket seats 55 are opened below the bit holder 54. It should be noted that the tools used by the operator during the maintenance and repair process can be stored on the storage plate 5. They can be neatly organized according to the provided bracket 53 and bit holder 54. The socket seats 55 arranged below can receive the sockets 96 through the inwardly contracting side walls and be placed according to different models, facilitating the operator to pick up.

[0063] Refer to Figure 7 and Figure 8, on the side of the connection mechanism 4 away from the workbench 3, an assembly plate 6 is installed. One end of the assembly plate 6 is fixedly connected with a mounting seat 61. The mounting seat 61 is detachably connected to the vertical plate 43 through multiple groups of bolts. The bottom of the other end of the assembly plate 6 is connected to the top of the connecting seat 29. An internal thread hole 63 is provided in the groove 62 opened on the assembly plate 6. A hinge 64 is installed on one side of the groove 62. A cover plate 65 is connected to the hinge 64. Two bending parts are provided on the cover plate 65. It should be noted that the end of the cover plate 65 abuts against the inner wall of the groove 62, which can fix the cover plate 65. By respectively corresponding the bending parts provided on the cover plate 65 to the screw rod 73 and the first pin shaft 82, the stability of the positioning mechanism 7 and the auxiliary mechanism 8 can be improved, and the shaking that occurs after the position of the positioning mechanism 7 is fixed can be reduced.

[0064] In the above technical solution, an embodiment of the positioning mechanism 7 is as follows:

[0065] Referring to Figure 9 And Figure 10 , a groove 62 is opened on the upper surface of the assembly plate 6. The positioning mechanism 7 and the auxiliary mechanism 8 are arranged in the groove 62. The positioning mechanism 7 includes an extension plate 71. A through groove 72 is opened on the extension plate 71. One end of the extension plate 71 is provided with a screw rod 73. The screw rod 73 is arranged in the through groove 72 and corresponds to the position of the internal thread hole 63. A gasket 74 is installed between the screw rod 73 and the extension plate 71, and the diameter of the gasket 74 is larger than the width of the through groove 72. The other end of the extension plate 71 is fixedly connected with a connecting block 75. The side wall of the connecting block 75 away from the extension plate 71 is fixedly connected with an abutting plate 76, and the side walls of the abutting plate 76 are all arc-shaped. It should be noted that by adjusting the screw rod 73 and cooperating with the provided gasket 74, the fixing of the extension plate 71 can be released. In coordination with the through groove 72 opened on the extension plate 71, according to the bolts at the installation points of the mechanical equipment, the length and angle of the extension plate 71 are adjusted so that the abutting plate 76 is located at the installation point, and according to the gap of the mechanical equipment itself, the corresponding side wall of the abutting plate 76 is selected to abut against the ear plate at the bolt installation place, so as to support the mechanical equipment to be disassembled, reduce the influence of the inconvenient support due to the shape and structure of the bottom of the mechanical equipment itself, and facilitate positioning during reinstallation after maintenance.

[0066] In addition, the auxiliary mechanism 8 includes a first auxiliary plate 81. One end of the first auxiliary plate 81 is rotatably connected to the bottom inner wall of the groove 62 through a first pin shaft 82. The other end of the first auxiliary plate 81 is rotatably connected to a second auxiliary plate 84 through a second pin shaft 83. One end of the second auxiliary plate 84 away from the second pin shaft 83 is rotatably connected to a third pin shaft 85, and the third pin shaft 85 is connected to the side wall of the extension plate 71. Further, by providing the first pin shaft 82, the second pin shaft 83 and the third pin shaft 85, the first auxiliary plate 81 and the second auxiliary plate 84 can rotate flexibly to cooperate with the adjustment of the position of the extension plate 71, improve the load-bearing performance of the extension plate 71, avoid deformation of the extension plate 71 caused by the excessive self-weight of the mechanical equipment, and when the storage plate 5 is laid flat, it can increase the contact with the lower surface of the storage plate 5 and improve the stability of the storage plate 5.

[0067] Refer to Figures 11-13 , a disassembly mechanism 9 is installed at one end of the positioning mechanism 7 away from the assembly plate 6. The disassembly mechanism 9 includes a first movable rod 91, and the first movable rod 91 is slidably and penetratingly connected to the connecting block 75. A top block 911 is fixedly connected to the top of the first movable rod 91. A second movable rod 92 is slidably and penetratingly provided on the top block 911. One end of the second movable rod 92 is fixedly connected to a sphere 921. A ferrule 922 is installed at the other end of the second movable rod 92. A lower joint 93 is embedded in the ferrule 922, and the lower joint 93 is rotatably connected to the ferrule 922. A first transverse groove 931 is formed at the top of the lower joint 93. A first connecting shaft 932 is rotatably and penetratingly provided at the top of the lower joint 93. A liquid injection hole 933 is formed in the lower joint 93. An upper joint 94 is provided above the lower joint 93. A second transverse groove 941 is formed at the bottom of the upper joint 94. A second connecting shaft 942 is rotatably and penetratingly provided at the bottom of the upper joint 94. A convex head 943 is provided at the upper end of the upper joint 94. An engagement frame 95 is provided between the first transverse groove 931 and the second transverse groove 941, and the engagement frame 95 is connected to the first connecting shaft 932 and the second connecting shaft 942 at the same time.

[0068] Specifically, during the disassembly and repair process, select the corresponding socket 96 according to the bolt model at the installation point of the mechanical equipment, and snap the socket 96 onto the bottom of the lower joint 93. With the first movable rod 91 and the second movable rod 92 arranged in cooperation, adjust the position of the lower joint 93 until the socket 96 is sleeved on the bolt at the installation location of the mechanical equipment. The operator can connect a conventional wrench to the head 943 at the top of the upper joint 94. During the repair process, only the same wrench needs to be used for operation, without the need to carry other wrenches of different models and sizes, reducing the labor intensity of the operator. Further, through the connection of the connecting frame 95, the angle between the lower joint 93 and the upper joint 94 can be flexibly changed. When the operator holds the wrench for disassembly, the position and angle of the wrench can be flexibly adjusted according to the space limitation of the mechanical equipment itself, avoiding increasing the disassembly difficulty due to limited operation space. At the same time, in the extending direction of the torque, the disassembly can be carried out more labor-savingly.

[0069] In addition, a socket 96 is snap-connected to the bottom of the lower joint 93. An infusion hole 961 is provided on the socket 96, and the infusion hole 961 is communicated with the liquid injection hole 933. It should be noted that during the disassembly process, it is relatively difficult to directly disassemble the corroded bolt. The corresponding chemical agent can be sprayed into the liquid injection hole 933 provided on the lower joint 93 and flow to the infusion hole 961 along the liquid injection hole 933. At this time, the socket 96 is sleeved on the bolt at the installation location of the mechanical equipment, and the top of the bolt with relatively severe rust under normal conditions can be soaked. The chemical agent gradually flows downward through the gap between the socket 96 and the top of the bolt, extending the contact time between the chemical agent and the bolt, comprehensively treating the rusted part of the bolt, and reducing the subsequent disassembly difficulty.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
