Description

Technical Field

[0001] This utility model relates to air compressors, and more particularly to a mobile screw air compressor. Background Technology

[0002] An air compressor is a machine used to compress gas, increase gas pressure, or transport gas. Air compressors have a wide range of applications, spanning almost every field, including industry, agriculture, science and technology, and civilian use. The air compressor is the main component of an air source device; it converts the mechanical energy of a prime mover (usually an electric motor) into gas pressure energy, and is the device that generates compressed air pressure. Commonly used air compressors include reciprocating air compressors, screw air compressors, centrifugal air compressors, vane air compressors, and scroll air compressors. Screw compressors are positive displacement gas compression machines with a rotating working volume. Most air compressors on the market are currently immobile; they are typically moved by forklifts or hoisting through forklift holes in the frame, making them very inconvenient to use.

[0005] The compressor body includes a frame and a main unit, and the main unit includes a transmission part, a power distribution part, an oil-gas separator and a cooling part;

[0006] The cooling unit is fixed to the side of the frame, and the side door panel of the frame is provided with an air outlet corresponding to the position of the cooling unit; the top door panel of the frame is sealed; the front door panel of the frame is provided with a louvered air inlet, and the front door panel of the frame is provided with a baffle for blocking water above the air inlet.

[0007] The transmission part is connected to the oil-gas separator, and the oil-gas separator is connected to the cooling part via hoses.

[0008] The walking assembly includes a tire, a hub, a bearing, an oil seal, and a square steel tube. The square steel tube is welded to the bottom of the frame and is divided into a first part extending along the width of the frame and a second part extending along the length of the frame. A bushing is welded to the first part, and the axle is welded to the bushing. The oil seal, the first bearing, the second bearing, and the hub are assembled together on the axle. The tire is connected to the hub by bolts. The second part extends out of the frame and is supported by a support foot.

[0009] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0010] This utility model discloses a mobile screw air compressor, in which the cooler is located on the side, hot air is blown out from the side, the air inlet adopts louvers and baffles, and the top door is completely sealed, making it suitable for outdoor harsh weather. It has strong waterproof performance, and all pipeline connections use flexible hoses. When moving, there is a lot of vibration. Compared with rigid pipes, flexible hoses have better shock resistance. At the same time, the mobile structure composed of square steel pipes, axles, hubs, tires, etc. can solve the problem of existing air compressors being too heavy and difficult to move.

[0015] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0016] refer to Figures 1-4 This embodiment provides a mobile screw air compressor, including a compressor body and a walking assembly;

[0017] The compressor body includes a frame 12 and a main unit, the main unit including a transmission part 1, a power distribution part 2, an oil-gas separator 3 and a cooling part 4;

[0018] The cooling unit is fixed to the side of the frame 12. The side door panel of the frame 12 is provided with an air outlet corresponding to the position of the cooling part 4. The top door panel of the frame 12 is sealed. The front door panel of the frame 12 is provided with a louvered air inlet. The front door panel of the frame 12 is provided with a baffle for blocking water above the air inlet.

[0019] The transmission part 1 is connected to the oil-gas separator tank, and the oil-gas separator tank 3 is connected to the cooling part 4 via hoses.

[0020] The walking assembly includes a tire 5, a hub 6, a first bearing 7, a second bearing 8, an axle 9, an oil seal 10, an axle plug 11, and a square steel tube 13. The square steel tube 13 is welded to the bottom of the frame 12 and is divided into a first part extending along the width direction of the frame 12 and a second part extending along the length direction of the frame 12. The bushing is welded to the first part, the axle 9 is welded to the bushing, and the oil seal 10, the first bearing 7, the second bearing 8, and the hub 6 are assembled together on the axle 9. The tire 5 is assembled and connected to the hub 6 by bolts. The second part extends out of the frame 12 and is supported by the ground through the support feet 14.
