Description

Technical Field

[0001] The utility model relates to a full-functional hydraulic drive system for a suction and pressure delivery vehicle, belonging to the technical field of suction and pressure delivery vehicles. Background Art

[0002] A suction and pressure delivery vehicle is a special vehicle designed to transport powdery or granular materials. This vehicle combines the technologies of negative pressure suction and positive pressure discharge. It uses the negative pressure generated by a vacuum pump to suck materials into the vehicle's storage tank for easy transportation, and then uses the positive pressure generated by compressed gas or other means to discharge the materials in the storage tank. It is applicable to various powdery or granular materials, such as cement, lime powder, coke powder, coal powder, dust removal ash, etc., and can complete the loading, transportation, and unloading of materials under closed conditions. It is widely used in: the metallurgical industry, such as the transfer of dust materials generated in the iron-making and steel-making processes of steel mills. The chemical industry, such as the treatment of dust materials in the energy chemical and energy power industries. The building materials industry, such as the transfer of materials in cement plants and glass plants. The environmental protection industry, such as the treatment of environmental and process dust removal ash in various factories.

[0003] The suction function of the suction and pressure delivery vehicle requires a vacuum pump, the pressure delivery function requires an air compressor, and each hydraulic boom, the switch of the rear cover plate, and the lifting device, etc. also require a hydraulic oil pump to provide kinetic energy. The vacuum pump, air compressor, and hydraulic oil pump all require independent power sources, while the traditional diesel vehicle chassis can only provide one or two power outputs (commonly known as motor power take-offs). Although it is also possible to additionally install a power take-off and a transfer case through power transformation to meet the needs of the three kinds of power, the transformation itself is not easy, and the pure mechanical power transmission output is restricted by the shape constraints of the mechanical structure, resulting in the vehicle having to be designed limited to the position of the power source during design, greatly hindering the freedom of vehicle design. The emergence of the new energy vehicle chassis with pure electric drive has provided new options for environmental protection and energy conservation, but the power output has obvious limitations. Most pure electric chassis can only provide a small power output. If it is necessary to meet the needs of these three kinds of power, it is necessary to additionally configure a dedicated battery pack or motor, and the cost is very high.

[0004] Therefore, to meet the three independent power requirements of the suction and pressure delivery vehicle, a large number of modifications and additional drive components need to be made on the chassis, and such operations will also lead to various constraints and limitations in the vehicle-mounted space, weight, and layout.

[0005] Therefore, those skilled in the art have been looking for a new, more convenient and useful solution to improve the flexibility of vehicle design. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a new technical solution to improve or solve the technical problems existing in the prior art as described above.

[0007] The technical solution provided by the utility model is as follows: A full-functional hydraulic drive system for an attracting and conveying vehicle, including a hydraulic oil pump, a hydraulic distributor, and at least two independent hydraulic motors. The hydraulic oil pump is driven by a motor power take-off on an existing vehicle chassis. The hydraulic oil pump transfers the power of the hydraulic oil to the hydraulic motors through the hydraulic distributor, which is used to control the amount of hydraulic oil distributed to each hydraulic motor. The hydraulic distributor is also connected with a hydraulic multi-way valve through an oil circuit. The hydraulic multi-way valve is used to provide hydraulic oil for various hydraulic drive components and control the flow direction of the hydraulic oil.

[0008] Further, the hydraulic motors include a hydraulic motor A and a hydraulic motor B. The hydraulic motor A is used to drive an air compressor, and the hydraulic motor B is used to drive a vacuum pump.

[0009] Further, the hydraulic multi-way valve is respectively connected with a hydraulic lifting cylinder, hydraulic outriggers, and a rear cover oil cylinder.

[0010] The technical solution provided by the utility model has the following beneficial effects compared with the prior art:

[0011] The chassis only needs to provide 1 power output end. The hydraulic oil pump is driven through the power output end, and then the hydraulic oil is distributed to the hydraulic motors and the hydraulic multi-way valve through the hydraulic distributor. Among them, the hydraulic motor A and the hydraulic motor B are used to drive the vacuum pump and the air compressor, and the hydraulic multi-way valve is directly connected to the hydraulic lifting cylinder, hydraulic outriggers, and the tailgate hydraulic cylinder. Since the hydraulic pipeline can be bent arbitrarily, the driving parts of the vacuum pump and the air compressor are no longer limited to the position of the traditional motor power take-off, thus greatly improving the design freedom of the vehicle.

[0012] Without modifying the chassis, this solution uses a low-power power output end to drive the hydraulic oil pump. By virtue of the characteristic that the power of the hydraulic system can be transmitted arbitrarily along with the bending of the hydraulic pipe, it solves the drawback that the traditional vehicle design must be restricted by the position of the mechanical power take-off, meets the 3 power requirements of the full-functional attracting and conveying vehicle, does not require adding a battery pack and a motor power take-off, has a simple structure, and the whole vehicle is light in weight. Furthermore, the selection types of the chassis of the attracting and conveying vehicle can be extended to the chassis of diesel vehicles, natural gas vehicles, pure electric vehicles, hydrogen energy vehicles, etc. Further expanding the space for vehicle design and increasing the space for customer selection.

[0015] Such as Figure 1As shown in the figure, a full-functional hydraulic drive system for an attracting and transporting vehicle includes a hydraulic oil pump, a hydraulic distributor, and a hydraulic motor. The hydraulic oil pump is driven by a motor power take-off (i.e., the power system) on the chassis. The hydraulic oil pump and the hydraulic distributor are connected through an oil circuit. The hydraulic distributor is respectively connected to the hydraulic motor and the hydraulic multi-way valve through an oil circuit.

[0016] Specifically, the hydraulic motor includes a hydraulic motor A and a hydraulic motor B. The hydraulic motor A is used to drive an air compressor, and the hydraulic motor B is used to drive a vacuum pump.

[0017] Specifically, the hydraulic multi-way valve is respectively connected to a hydraulic lifting cylinder, hydraulic outriggers, and a rear cover oil cylinder.

[0018] The working principle of the present utility model: During material suction: The hydraulic oil pump is driven to operate by the power system, and the hydraulic oil is distributed to the hydraulic motor A through the hydraulic distributor. The hydraulic motor A provides power for the vacuum pump to make it work to generate a vacuum in the tank body, suck the material into the storage tank. After the tank body is full, the vacuum pump is closed, and the attracting and transporting vehicle transports the material to the discharging operation point.

[0019] During material discharging: The hydraulic oil pump is started, and the hydraulic oil is transmitted to the hydraulic outriggers through the hydraulic multi-way valve. The hydraulic outriggers are lifted. The power system drives the hydraulic oil pump to operate, and the hydraulic oil is distributed to the hydraulic motor B through the hydraulic distributor. The hydraulic motor B provides power for the air compressor. The air compressor is started to pressurize the storage tank, and at the same time, pressurize the fluidized bed in the storage tank to make the material in the tank body in a state similar to boiling, which is beneficial to the discharge of the material, and the material is discharged into the ground receiving bin. When the material in the storage tank is nearly discharged, the hydraulic oil is transmitted to the hydraulic lifting cylinder through the hydraulic multi-way valve, and the hydraulic lifting cylinder is started to lift the storage tank, and the remaining material in the storage tank is discharged from the storage tank under the action of gravity.

[0020] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
