Detailed implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0020] An engineering machinery air compressor convenient for maintenance includes a metal shell 1 of the air compressor. Side top cover bodies 2 are symmetrically arranged at the upper left and upper right positions of the metal shell 1 of the air compressor. The front and rear ends of the bottom of the side top cover body 2 are respectively fixedly connected with vertical plates 3. Side card slots 4 are respectively opened at the front and rear ends of one side inside the metal shell 1 of the air compressor. A horizontal plate 5 is arranged below the inside of the side card slot 4. A fixed square box 6 is fixedly connected above the inside of the side card slot 4. A telescopic rod 7 is arranged at the middle position of the bottom end of the fixed square box 6. Guide posts 8 are respectively fixedly connected at both sides of the bottom end of the fixed square box 6. Movable switches 9 are arranged adjacent to each other before and after the position close to the inner side surface of the side card slot 4 of the telescopic rod 7. A square card slot for clamping the movable switch 9 is arranged inside the metal shell 1 of the air compressor. The arc end of the movable switch 9 extends into the inside of the side card slot 4.

[0021] Such as Figure 1As shown in the figure, a base 15 is fixedly connected to the bottom end of the metal shell 1 of the air compressor. At both sides of the bottom of the base 15, moving brackets 16 are respectively fixedly connected. At the front and rear ends of a single moving bracket 16, rolling wheels 17 are respectively rotatably connected. There are 4 rolling wheels 17 in total. After the device is rotatably connected to the 4 rolling wheels 17 through 2 moving brackets 16 respectively, this structural setting will facilitate the entire device to utilize the flexibility of the rolling wheels 17 to move freely in a special environment; in the middle position of the front end of the metal shell 1 of the air compressor, there is a movable maintenance door 12. At the upper middle position of the front end of the movable maintenance door 12, a front connecting shaft 13 is fixedly connected. The outer part of the front connecting shaft 13 is rotatably connected with a clamping frame 14. The clamping frame 14 is fixedly connected to the metal shell 1 of the air compressor. Since the movable maintenance door 12 is rotatably connected to the clamping frame 14 through the front connecting shaft 13, this connection structure will form a hinged rotation structure, so that subsequent workers can quickly manually open the 4 movable maintenance doors 12 arranged on the four sides of the metal shell 1 of the air compressor in a front-back flipping manner.

[0022] As Figure 1 , Figure 2 , Figure 3 and Figure 4 shown in the figure, a combined mesh plate 11 is arranged at the middle position of the top end surface of the side top cover body 2. A cylindrical lamp 10 is clamped at the bottom end surface of the side top cover body 2. There are 4 rows of cylindrical lamps 10 in total. The light source of the cylindrical lamp 10 is arranged towards the inside of the metal shell 1 of the air compressor. When the horizontal plate 5 moves upward and squeezes the movable switch 9, multiple cylindrical lamps 10 will be turned on and emit light, so as to provide auxiliary lighting towards the inside of the metal shell 1 of the air compressor; the vertical plate 3 and the horizontal plate 5 are fixedly connected. The connection between the horizontal plate 5 and the vertical plate 3 forms an "L"-shaped structure. Circular slots for sliding connection with the guide posts 8 are opened at both side ends of the horizontal plate 5. The guide posts 8 are arranged inside the side card slots 4 and fixedly connected to the metal shell 1 of the air compressor. One end of the horizontal plate 5 is connected to the movable end of the telescopic rod 7. When the "L"-shaped structure composed of the vertical plate 3 and the horizontal plate 5 moves up and down along the inside of the side card slot 4, the sliding connection and cooperation between the guide posts 8 and the horizontal plate 5 will provide guiding and auxiliary limitation for the moving action of the "L"-shaped structure.

[0023] Workflow: All the electric energy required for the startup and operation of the electrical equipment in this utility model comes from an external power supply. Multiple rows of tube lights 10 are connected in series and then electrically connected to multiple movable switches 9 respectively. When using this construction machinery air compressor in a harsh outdoor environment, the entire device can be conveniently moved to the designated processing position through 4 rolling wheels 17, so that the device can quickly carry out the corresponding gas compression operation. At the same time, when it is necessary to perform regular maintenance and protection operations on the entire device, first, as the staff sequentially opens the four movable inspection doors 12 respectively arranged at the four positions on the metal shell 1 of the air compressor from back to front, and is limited by the way of inserting the bolt into the central card slot. Under the guiding and limiting action of the guide post 8, 2 groups of telescopic rods 7 can be started simultaneously, so that they can drive the side top cover body 2 to move upward through a set of "L"-shaped structures composed of the horizontal plate 5 and the vertical plate 3, so as to locally open the top side end of the entire device, so that the staff can conveniently carry out maintenance and repair operations from the upper two sides of the device. Moreover, when the horizontal plate 5 moves upward to a specified height, the horizontal plate 5 will squeeze the movable switch 9 inside the square card slot, so that the multiple rows of tube lights 10 can be turned on and emit light toward the inside of the metal shell 1 of the air compressor, so as to provide a reliable light source for the subsequent maintenance operations that need to be carried out at night.
