[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be pointed out that the embodiments described below are intended to facilitate the understanding of the present invention and do not have any limiting effect on the present invention.

[0022] Example 1

[0023] like Figure 2 As shown, the utility model provides a frame for integrally hoisting an auxiliary air compressor of a high-speed EMU, comprising a first frame 1 for installing an electrical control system and a second frame 2 for installing pipelines and an auxiliary air supply system, wherein the tops of the first frame 1 and the second frame 2 are fixedly connected to a top frame 3 and the top frame 3 forms the two into a whole; the top frame 3 is provided with a lifting lug 4 for hoisting the frame as a whole to a vehicle body; the top frame 3 is also provided with an air cylinder hanger 3-1 for hoisting an air cylinder and a pipe hanger 3-2 for hoisting a pipe on one side close to the second frame 2.

[0024] The top frame 3 is a frame body shared by the first frame 1 and the second frame 2, connecting the first frame 1 and the second frame 2 as a whole, thereby improving the integration of the frame. During installation, it is only necessary to hoist the frame to the car body through the lifting lug 4. There is no need to first hoist the main frame A and then hoist the auxiliary air supply unit frame C at the bottom of the main frame A like the frame in the prior art, thereby achieving the effect of simple structure and convenient assembly. In addition, since the frame of the prior art is a split structure, in order to ensure the firmness of the connection between the split frames, only high-strength carbon steel can be used as the material, which invisibly increases the weight of the train. Therefore, it is difficult to achieve lightweight structure using the prior art. After adopting the integrated structure of the present application, since the integrity of the device is enhanced, lightweight improvements can be made. Based on the above structure of the present application, the entire frame is made of aluminum alloy, and the weight is reduced by about 54kg after optimization.

[0025] The electrical control system is an electrical control and detection device integrated with the auxiliary air supply unit. Its main function is to effectively match the high-voltage equipment control and electrical logic control of the whole vehicle, so as to realize the requirements of "ground protection input and removal control, high-voltage equipment interlocking control, and pantograph and VCB action air source supply control" of the EMU. The electrical control system is mainly composed of air circuit board, air circuit device box, pressure regulator, solenoid valve, push button switch, plate-type two-way valve, plate-type three-way valve, pressure gauge, working air cylinder, power connector and other components.

[0026] The auxiliary air supply system is a compressor air generation and processing device, designed according to the principle of the unified air circuit of China's standardized EMU, and its main function is to provide dry and clean compressed air. The auxiliary air supply system is mainly composed of three parts: air compressor, back-blowing air cylinder and pipeline. The pipeline composition includes hose, radiator, safety valve, dryer and other components. The air compressor generates compressed air, which passes through the hose, radiator, safety valve, dryer, air cylinder and other components in turn to effectively provide stable and pure compressed air.

[0027] The electrical control system and the auxiliary air supply system are conventional technical means in this field and will not be described in detail here.

[0028] like Figure 1 As shown, in the framework of the prior art, the power connector and the pantograph riser are both installed on one side of the air path device box frame B, and a plurality of air outlets are arranged on one side of the air path device box frame B. This structure has a low degree of concentration. In order to further optimize the overall structure of the auxiliary air compressor and the lifting frame, the present application adopts the following implementation scheme.

[0029] like Figure 2 As shown, a mounting plate 5 for mounting a power connector and an air outlet is provided at the connection between the second frame 2 and the top frame 3. There are several air outlets, on which an air outlet seat 5-1 is fixed. (The power connector and the air outlet are not shown in the figure. Figure 2 The bold dotted line on the mounting plate is where the power connector is installed.

[0030] As a specific implementation scheme, Figure 4 As shown, the air outlet seat 5-1 includes a fixing plate 5-11 for fixing the air outlet seat 5-1 on the mounting plate 5 and a connecting pipe 5-12 for ventilation; the fixing plate 5-11 is provided with a fixing hole 5-111. When fixing, the fixing plate 5-11 is fixed to the mounting plate 5 by passing a bolt through the fixing hole 5-111. Although this method can achieve relative fixation between the air outlet seat 5-1 and the mounting plate 5, the fixing strength is not large, and since the overall frame is made of aluminum alloy, it is necessary to further strengthen the firmness between the air outlet seat 5-1 and the mounting plate 5. For this reason, based on the above technical solution, the fixing plate 5-11 forms a limiting block 5-13 on the side away from the connecting pipe 5-12, and the circumferential surface 5-131 of the limiting block 5-13 is a non-cylindrical surface, and the mounting plate 5 is provided with a through hole (not shown in the figure) adapted to the circumferential surface 5-131 of the limiting block 5-13. The non-cylindrical circumferential surface 5-131 may have many shapes, such as Figure 4 The cross-section in the structure is similar to an elliptical structure, or it can be a structure with a triangular, square or rectangular cross-section, which will not be described in detail here.

[0031] During installation, the limit block 5-13 is embedded in the through hole of the mounting plate 5. Since the through hole is matched with the circumferential surface 5-131 of the limit block 5-13, the rotation of the air outlet seat 5-1 relative to the mounting plate 5 can be limited. Afterwards, the fixing plate 5-11 is fixed to the mounting plate 5 by passing bolts through the fixing holes 5-111, thereby achieving the connection stability and firmness between the air outlet seat 5-1 and the mounting plate 5.

[0032] The fixing plate 5-11, the connecting pipe 5-12 and the limiting block 5-13 are an integrated structure, and the material can be made of high-strength carbon steel.

[0033] There are several air outlets on the mounting plate 5. Figure 4 Four are shown, namely the MR port, the ground protection break port, the ground protection closing port and the VCB port.

[0034] like Figure 2 and 3 As shown, the second frame 2 is provided with a mounting seat plate 6 for installing the air outlet of the pantograph riser connected to the vehicle on the opposite side of the hoisting air cylinder side, and a mounting seat 6-1 is provided on the air outlet of the pantograph riser connected to the vehicle.

[0035] As a specific implementation scheme, Figure 5 As shown, the mounting seat 6-1 includes a mounting seat fixing plate 6-11 for fixing the mounting seat 6-1 to the mounting seat plate 6 and an airway seat 6-12 formed with an airway 6-121.

[0036] In the framework of the prior art, the power connector and the air outlet of the pantograph riser of the Unicom vehicle are both arranged on one side of the air path device box frame B. Therefore, there is no interference problem between the two when the pipelines are laid out. However, when performing intensive design, since the power connector is arranged on the mounting plate 5 (the mounting seat plate 6 and the mounting plate 5 are perpendicular to each other), at this time, there will be a conflict between the pipeline connected to the power connector and the pipeline connected to the mounting seat 6-1. In order to solve this technical problem, based on the above technical solution, the air duct 6-121 is at a right angle. In the use state, the air inlet of the air duct 6-121 is facing away from the mounting plate 5 (such as Figure 6 This arrangement can effectively avoid the conflict between the pipe connected to the power connector and the pipe connected to the mounting seat 6-1. Figure 5 The arrow in the figure indicates the direction of gas flow in the airway 6-121.

[0037] The function of the mounting seat fixing plate 6-11 is the same as that of the fixing plate 5-11. When fixing, bolts are used to fix the mounting seat fixing plate 6-11 to the mounting seat plate 6. Similarly, the fixing strength is not large, so the firmness between the mounting seat 6-1 and the mounting seat plate 6 must be further strengthened. For this reason, based on the above-mentioned technical solution, the mounting seat fixing plate 6-11 is formed with a mounting seat limit block 6-13 on the side away from the airway seat 6-12. The structure is the same as that of the limit block 5-13. The circumferential surface of the mounting seat limit block 6-13 is a non-cylindrical surface. The mounting seat plate 6 is provided with a through hole that is compatible with the circumferential surface of the mounting seat limit block 6-13, which is no longer shown in the figure. There are many shapes of non-cylindrical circumferential surfaces, such as Figure 5 The cross-section in the structure is similar to an elliptical structure, or it can be a structure with a triangular, square or rectangular cross-section, which will not be described in detail here.

[0038] The mounting seat fixing plate 6-11, the airway seat 6-12 and the mounting seat limit block 6-13 are an integrated structure, and the material can also be made of high-strength carbon steel.
