[0032] As Figure 1-2 shown, the present utility model provides a dual-purpose operation transport vehicle, including a transport vehicle main body 1. The transport vehicle main body 1 includes a vehicle frame 101. One end of the vehicle frame 101 is provided with a towing bar 105, and a coupler towing ring 106 is provided on the towing bar 105. The coupler towing ring 106 is movably connected to a coupler towing seat 3. The bottom of the other end of the vehicle frame 101 is provided with a plurality of support legs 102. A axle and tire assembly 103 is provided at the bottom of the vehicle frame 101. An air suspension system 4 is provided between the vehicle frame 101 and the axle and tire assembly 103. An air compressor 104 communicating with the air suspension system 4 is provided inside the vehicle frame 101; the air suspension system 4 includes an airbag assembly 401, a height valve assembly 402, a shock absorber assembly 403, and a leaf spring assembly 404; an operation attachment is provided on the top of the vehicle frame 101.

[0033] Specifically, the transport vehicle main body 1 adopts pneumatic brakes, and the brake system is in a normally closed state under non-operation conditions; the towing bar 105 plays a supporting role for the coupler towing ring 106. During operation, the coupler towing ring 106 is rotatably connected to the coupler towing seat 3, and the coupler towing seat 3 can be installed on an excavator main body 2 or a towing vehicle main body 6. The transport vehicle main body 1 is towed by the excavator main body 2 or the towing vehicle main body 6 to complete processes such as walking and turning; the transport vehicle main body 1 can be separately placed after disconnecting the coupler towing seat 3 as needed; before the transport vehicle main body 1 is disconnected from the excavator main body 2 or the towing vehicle main body 6, a plurality of support legs 102 are opened. The height of the support legs 102 is adjustable, which can ensure that the transport vehicle main body 1 adapts to complex road conditions in the separately placed state. At the same time, the excavator main body 2 and the towing vehicle main body 6 can more conveniently access and replace the operation attachments carried by the transport vehicle main body 1, and the operation is more flexible; optionally, the coupler towing ring 106 is coupled to the coupler towing seat 3; optionally, the number of support legs 102 is four; optionally, the number of height valve assemblies 402 is one to three.

[0034] The utility model is matched through a coupler towing ring 106 and a coupler towing seat 3, and the corresponding coupler towing seat 3 can be installed on an excavator main body 2 and a towing vehicle main body 6, and can be respectively connected with the excavator main body 2 and the towing vehicle main body 6, so that the application can simultaneously meet the requirements of excavator towing in complex working conditions and towing transportation of a towing vehicle for long-distance transfer, reduce costs, and ensure the practicability and adaptability of the device; the time-consuming and laborious processes such as the unloading and loading of working implements on a transport vehicle main body 1 are avoided, and the flexibility and reliability of complex open-air operations are effectively improved.

[0035] As Figure 2 shown, in an embodiment, both ends of the leaf spring assembly 404 are respectively connected to the vehicle frame 101 through the airbag assembly 401 and the shock absorber assembly 403, and the height valve assembly 402 and the airbag assembly 401 are respectively connected to an air suspension air circuit system through pipelines.

[0036] Specifically, when the excavator main body 2 towes the transport vehicle main body 1 under complex road conditions such as uneven bumps, when the axle tire assembly 103 is in an unbalanced state due to the elevation or depression of a single-side tire, the height valve assembly 402 can timely adjust the air circuit switch of the corresponding airbag assembly 401 through the air suspension air circuit system; when the tire rises, the height valve assembly 402 opens the exhaust valve, and the gas in the corresponding airbag assembly 401 is discharged, reducing the height of the corresponding side of the air suspension; when the tire drops, the height valve assembly 402 opens the intake valve, and the corresponding airbag assembly 401 is filled with gas and the height rises; the air suspension system 4 can timely adjust the height of a single-side suspension, keeping the loading plane of the working implement on the vehicle frame 101 always in a horizontal state; this design can significantly increase the stability and working-condition adaptability of the transport vehicle main body 1.

[0037] The transport vehicle main body 1 of the present application uses the air suspension system 4, which can timely adjust the height of a single-side suspension, keeping the loading plane of the working implement on the vehicle frame 101 always in a horizontal state; this design can significantly increase the stability and working-condition adaptability of the transport vehicle main body 1.

[0038] As Figure 3 shown, in an embodiment, it further includes an air pipeline system, and the air pipeline system includes the air compressor 104. The input end of the air compressor 104 is connected to the wire harness assembly one 5, the output end of the air compressor 104 is connected to the input end of the ball valve 109, the output end of the ball valve 109 is connected to the first input end of the air storage cylinder 112, the output end of the air storage cylinder 112 is connected to the brake control system 113, and a pressure switch 108 is connected to the input end of the ball valve 109;

[0039] It further includes a dual release valve 110. The input end of the dual release valve 110 is connected to the control air pipe assembly 9. The first output end of the dual release valve 110 is connected to the first input end of the relay valve 111. The first output end of the relay valve 111 and the second output end of the dual release valve 110 are both connected to the second input end of the air storage tank 112. The second output end of the relay valve 111 and the third output end of the dual release valve 110 are both connected to the brake control system 113. The second input end of the relay valve 111 is connected to the always-open air pipe assembly 8. The output end of the air compressor 104 is connected to the input end of the ball valve 109 through an air circuit dual-component 107.

[0040] Specifically, when the excavator main body 2 is towing the transport vehicle main body 1, as Figure 3 shown, in this working condition, the always-open air pipe assembly 8 and the control air pipe assembly 9 are in a normally closed state. The excavator main body 2 supplies power to the air compressor 104 through the wire harness assembly one 5. At this time, the ball valve 109 is in an open state, and the air compressor 104 works to output compressed air, causing the air pressure in the air suspension system 4 and the air storage tank 112 system to rise. When the set pressure parameter is reached, the airbag assembly 401 of the air suspension system 4 reaches the set height and can work normally. Before the excavator main body 2 starts towing operation, operating the dual release valve 110 can release the normally closed state of the brakes of the transport vehicle main body 1. At this time, the excavator main body 2 can tow the transport vehicle main body 1 to work normally. Optionally, quick connection devices are provided at both ends of the wire harness assembly one 5. When the pressure switch 108 detects that the air suspension system 4 and the air storage tank 112 reach the upper limit set parameter of the pressure, the power supply of the air compressor 104 is disconnected. When the excavator main body 2 is towing the transport vehicle main body 1 in the towing working state, the airbag assembly 401 exhausting and inflating will reduce the air pressure in the system. When the lower limit set parameter of the pressure is reached, the pressure switch 108 receives the pressure signal feedback and restores the power supply of the air compressor 104. The air compressor 104 works again to supplement the pressure for the system. This design can effectively avoid the adverse effects of overheating caused by the long-term operation of the air compressor 104, and increase the service life and reliability of the air compressor 104. The air circuit dual-component 107 is used to filter impurities such as solid particles, liquid droplets and oil stains in the air source. At the same time, according to the set pressure value, it controls the output pressure of the air source to ensure the stability and reliability of the air source.

[0041] In the towing working condition of the towing vehicle main body 6, the ball valve 109 is in a normally closed state. The coupler towing seat 3 is installed at the rear of the towing vehicle main body 6. The coupler towing ring 106 of the transport vehicle main body 1 is coupled and connected to the coupler towing seat 3. The towing vehicle main body 6 towes the transport vehicle main body 1 to complete processes such as walking and turning. The towing vehicle main body 6 provides power for the transport vehicle main body 1 through the wire harness assembly two 7 and controls the rear taillights, side marker lights and brake control system 113 of the transport vehicle main body 1. As Figure 3As shown in the figure, the main body 6 of the tractor truck is respectively connected to the constant ventilation pipeline and the control pipeline of the main body 1 of the transport vehicle through the constant ventilation pipe assembly 8 and the control pipe assembly 9; the constant ventilation pipe assembly 8 provides air sources for the air suspension system 4 and the air storage tank 112; the main body 6 of the tractor truck controls the relay valve 111 and the brake control system 113 through the control pipe assembly 9 to achieve the synchronous braking control of the main body 1 of the transport vehicle and the main body 6 of the tractor truck; optionally, quick connection devices are provided at both ends of the harness assembly two 7, the constant ventilation pipe assembly 8 and the control pipe assembly 9.

[0042] The main body 1 of the transport vehicle in this application is designed with an air compressor 104. When the main body 2 of the excavator is in the towing state, only the power supply provided by the harness assembly one 5 is required to meet the working requirements of releasing the brakes of the main body 1 of the transport vehicle and the air suspension system 4, and at the same time, it can control the opening and closing of the rear lights and side marker lights of the main body 1 of the transport vehicle; this avoids the modification of the common structure of the main body 2 of the excavator and increases economic benefits.

[0043] As Figure 4 shown, in one embodiment, the working attachments include but are not limited to a grapple 10, a breaker 11, a pile driver 12, a rock drill 13, a hydraulic shear 14, a toolbox 15 and a bulldozer blade 16, which can be used for operations such as excavation, grasping, crushing, piling, chiseling, shearing, etc., to achieve the effect of a multi-functional operation transport vehicle, and improve the utilization rate and flexibility of the operation transport vehicle; the working attachments of the main body 1 of the transport vehicle are replaceable. Under complex working conditions, by replacing the working attachments, the effect of multi-attachment operations can be achieved, and the functionality and practicality of the product are improved.
