Referring to fig. 1 to 7, the embodiment discloses a power distribution cabinet carrying device, which comprises a vehicle body 100, a lifting part 200 and a lifting hydraulic cylinder 210, wherein the lifting part 200 is fixedly connected with the moving end of the lifting hydraulic cylinder 210, and the moving end of the lifting hydraulic cylinder 210 can move up and down relative to the vehicle body 100. The two-phase tank 300 is further included, and the two-phase tank 300 is filled with liquid and gas, thereby being divided into a gas phase zone 310 and a liquid phase zone 320, and the gas phase zone 310 and the liquid phase zone 320 are mutually extruded to jointly occupy the inner space of the two-phase tank 300. The lifting cylinder 210 is connected to the liquid phase zone 320 of the two-phase tank 300 by a pipe. The air box 400, the first air pumping device 500 and the second air pumping device 800 are further included, and air is stored in the air box 400 and is positive in pressure. The gas phase region 310 of the two-phase tank 300 is connected with the gas inlet of the first gas-pumping device 500 through a pipeline, the gas outlet of the first gas-pumping device 500 is connected with the gas tank 400 through a pipeline, the gas tank 400 is connected with the gas inlet of the second gas-pumping device 800 through a pipeline, and the gas outlet of the second gas-pumping device 800 is connected with the gas phase region 310 of the two-phase tank 300. The first and second pumping devices 500 and 800 may be operated manually to pump, and the greater the difference between the back-end air pressure and the front-end air pressure of the devices, the greater the force required for pumping.
The types of pumping devices, i.e., fluid conveying devices, are widely classified into non-positive displacement type, such as centrifugal type, axial flow type, etc., and positive displacement type, such as plunger type, gear type, screw type, etc., and in order to achieve the effect that the larger the difference between the air pressure at the rear end and the air pressure at the front end of the device is, the larger the force required for pumping is, and the air chamber is so that the air pressure at the front end can assist the pumping device to squeeze toward the rear end. The centrifugal type and the axial flow type are processes for further improving the pressure based on the original pressure of the gas, and obviously can achieve the effects, but the two types of the centrifugal type and the axial flow type are required to output rotational momentum finally, the rotational speed is required to be high, the manual work is usually converted into usable rotational momentum by means of motor or engine driving, and the mechanical structure is relatively complex, so that the centrifugal type and the axial flow type are not recommended. The first air pumping device 500 and the second air pumping device 800 of the present embodiment preferably adopt a plunger type design, and only need to provide unidirectional displacement for doing work manually. The first air pumping device 500 and the second air pumping device 800 have the same structure, specifically, taking the first air pumping device 500 as an example, the air pumping device comprises an air pump 510, an air pumping piston 520 is arranged in the air pump 510 in a sealing sliding manner, and the air pumping piston 520 is connected with an external manual operation structure, such as a pedal 540. The pumping piston 520 is provided with a one-way ventilation structure so that gas can only pass over the pumping piston 520 from above to below. The inlet and outlet of the pump 510 are provided with one-way valves 530, the inlet being located at the upper part of the pump 510 and the outlet being located at the lower part of the pump 510. Further, the air vent 521 penetrating up and down is provided on the air pumping piston 520, the flexible sheet 522 is provided on the lower surface of the air pumping piston 520, the partial area of the contact between the flexible sheet 522 and the lower surface of the air pumping piston 520 is fixed, the partial area is not fixed, so that the air can prop up the flexible sheet 522 from top to bottom, and the air can only make the flexible sheet 522 cling to the air pumping piston 520 from bottom to top, and the flexible sheet 522 cannot be propped up. Structures for achieving one-way ventilation are numerous in the art, such as one-way valve 530 products, and are not specifically disclosed herein. Further, when the pumping piston 520 is in the initial position, the sides should be just capable of blocking the inlet of the pump 510, thereby achieving a natural seal when not in operation. Further, the pumping means should also comprise a resilient member, such as a spring, pushing the pumping piston 520 home. Further, to prevent the liquid in the two-phase tank 300 from overflowing through the gas line, the gas and the liquid may be isolated by the soft capsule 330.
The principle and the application method of the embodiment are as follows:
in this embodiment, the lifting portion 200 is driven to move up and down by means of the extension and contraction of the lifting hydraulic cylinder 210, so that the power distribution cabinet is lifted and lowered. The first inflator 500 is capable of transferring gas from the two-phase tank 300 to the gas tank 400, and the second inflator 800 is capable of transferring gas from the gas tank 400 to the two-phase tank 300. By increasing or decreasing the volume of gas in the two-phase tank 300, the two-phase tank 300 is caused to squeeze or suck in liquid, thereby controlling the volume of liquid in the lifting hydraulic cylinder 210 and controlling the expansion and contraction of the lifting hydraulic cylinder 210. The larger the difference between the air pressure at the rear end and the air pressure at the front end of the first air pumping device 500 and the second air pumping device 800, the larger the force required for pumping. The pressure in the two-phase box 300 is positively correlated with the load of the lifting hydraulic cylinder 210, the weight of various cabinets to be carried is comprehensively considered, and the middle value of the air pressure in the two-phase box 300 is set when the air pressure in the air box 400 is close to the load and the air pressure in the no-load, so that when an operator uses the first air pumping device 500 and the second air pumping device 800 to transfer air, the pressure of the air at the front end can be utilized to directly pump the external air into the two-phase box 300, the labor is saved, and the pedals 540 are needed to be stepped on manually no matter the cabinet is lifted or put down, so that the light movement and the light release are realized, and the damage to the cabinet is avoided. In addition, vibrations in the process of carrying the cabinet body can be transferred to the two-phase box 300 through hydraulic pressure, and gas in the two-phase box 300 can absorb vibrations, thereby play the cushioning effect, moreover, the heavier the cabinet body is, the higher the atmospheric pressure in the two-phase box 300 is, the greater the damped hardness is, thereby the damped hardness can follow the load change and realize self-adaptation matching.
Specifically, when the cabinet is lifted, the second pumping device 800 needs to be operated, the air pressure in the air tank 400 is higher than the air pressure in the two-phase tank 300 just before the start, the operator only needs to lightly displace the pumping piston 520, so that the pumping piston 520 does not block the air inlet of the pump 510, the air naturally flows to the two-phase tank 300 under the action of the air pressure until the air pressures at the two sides reach equilibrium, then the pumping piston 520 is manually driven to press downwards, namely, the pedal 540 is stepped on, and the air is continuously extruded into the two-phase tank 300 until the lifting part lifts the cabinet. When the cabinet is put down, the first air-pumping device 500 needs to be operated, the air pressure in the two-phase box 300 is higher than the air pressure in the air box 400 at the beginning, and the air is naturally exhausted at first, then the potential energy is transferred into the air box 400 during manual air pumping, and the potential energy is used during the next lifting operation. It can be seen that, in the present embodiment, the operation of the first air pumping device 500 and the second air pumping device 800 by the operator is mainly to transfer potential energy between the two-phase box 300 and the air box 400, and the work of the operator is essentially only to supplement the potential energy lost in the transferring process, so that the labor-saving effect is obvious compared with the conventional manual lifting mechanism.
The construction site, the workshop, the warehouse and the transport vehicle are provided with the object placing wood special for placing the materials, the object placing wood is strip-shaped wood with square sections, a plurality of object placing woods are square on the ground, large-sized materials or material boxes are placed on the object placing woods, the materials can be prevented from being directly contacted with the hard ground, the materials are protected, the materials can be kept clean, and the space of the lifting structure such as a forklift and the like extending to the bottom of the materials can be reserved below the materials, so that the lifting part 200 is preferably in a structure similar to a fork of a forklift, and the lifting part 200 is moved to the lower side of the cabinet body through the mobile vehicle body 100 and then is lifted.
As a further scheme of this embodiment: the clamping hydraulic cylinder 600 is symmetrically distributed, the clamping hydraulic cylinder 600 can transversely stretch out and draw back, the clamping arms 610 are fixed at the output end, the two clamping arms 610 are symmetrically distributed on two sides of the cabinet body, and the clamping hydraulic cylinder 600 can be used for fixing by being close to the clamping cabinet body. The clamping cylinder 600 is connected to the liquid phase region 320 of the two-phase tank 300 by a pipe. The clamping portion operates in accordance with the change in the volume of the gas in the two-phase tank 300, similarly to the lifting portion 200.
As a further scheme of this embodiment: also included are a plurality of shock absorbing hydraulic cylinders 700 for coupling the vehicle body 100 to the wheels of the vehicle body 100 to provide shock absorption to the vehicle body 100. The damping hydraulic cylinder 700 is connected with the liquid phase region 320 of the two-phase tank 300 through a pipeline, and also acts along with the change of the gas volume of the two-phase tank 300, and the damping hardness can be adaptively matched along with the change of the load.
The lifting hydraulic cylinder 210 and the clamping hydraulic cylinder 600, especially the homing of the clamping hydraulic cylinder 600, can suck the liquid into the two-phase box 300 by adopting a mode of pumping the air pressure of the two-phase box 300 to the negative pressure, thereby realizing homing, and a better option is to set an elastic component to assist homing, so that the air pressure of the two-phase box 300 is not required to be pumped to the negative pressure, and the unloading of the cabinet body can be completed only by transferring a small amount of air. The use of elastic members is common knowledge and is not specifically developed herein.
The foregoing description of the preferred embodiments of the present invention should not be taken as limiting the invention, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
