Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology, and in particular to a vehicle body liquid dynamic balance stabilization system. Background Technology

[0002] Transportation equipment is the carrier that enables people or goods to be transported from one place to another. Based on the mode of transport, it can be divided into road transportation equipment, rail transportation equipment, air transportation equipment, waterway transportation equipment, and pipeline transportation equipment. Rail transportation equipment is usually a combination of tracks and transport equipment. The transport equipment moves on the tracks to transport materials, such as trains, subways, and monorails. Due to their convenience and speed, they have become indispensable tools for people's travel. However, such transport equipment, like monorails, can experience significant lateral swaying when running on curved sections or in crosswinds due to the lack of lateral restraints. Although trains have two rails for support, their track gauge is usually only half the width of the train, causing lateral swaying when passing through curved sections, windy areas, or when encountering oncoming trains.

[0003] To prevent the above phenomenon, existing technologies usually include damping components to suppress the left-right swaying of the vehicle body when subjected to lateral forces. For example, Chinese patent CN107985328A discloses a suspended aerial rail train that uses the damping force of damping components to slow down the speed of the vehicle body's lateral swaying. However, since damping components are generally mechanical structures, they are passively compensated during balance compensation, resulting in a slow response and significant instability of the vehicle body, which affects the passenger riding experience. Summary of the Invention

[0004] The purpose of this invention is to overcome the defects and problems of poor vehicle body operation stability in the existing technology, and to provide a vehicle body liquid dynamic balance stabilization system with higher stability.

[0005] To achieve the above objectives, the technical solution of this utility model is: a vehicle body liquid dynamic balance stabilization system, comprising: a liquid compensation component, wherein the liquid compensation component includes storage tanks located on the left and right sides of the top of the monorail vehicle body, the storage tanks are filled with liquid material, the lower ends of the two storage tanks are connected to each other through a connecting pipe, and a first extraction component is connected to one side of the two storage tanks, the first extraction component being used to extract the liquid material from one of the storage tanks into the other storage tank.

[0006] The first extraction component includes a bidirectional pump and a pipeline. One side of the two storage tanks is connected to the pipeline. Both water inlets of the bidirectional pump are connected to the pipeline. A vent is provided at the upper end of the storage tank.

[0007] The two storage bins are symmetrically arranged on the left and right sides of the longitudinal axis of the air rail vehicle.

[0008] The upper end of the storage box is provided with a filling port, and the lower end of the storage box is connected to a discharge pipe. The two ends of the connecting pipe are connected to the sides of the two discharge pipes, and the lower end of the discharge pipe is provided with a discharge port.

[0009] The inner wall of the storage box is provided with multiple speed reduction plates at intervals. The speed reduction plates are provided with honeycomb holes and are arranged alternately in the horizontal or vertical direction.

[0010] The connecting pipe includes two liquid pipes, one end of each of the two liquid pipes is connected to the middle of the two discharge pipes respectively, the other end of the two liquid pipes are connected and both are connected to a flange on the outside, and a connecting bolt is threaded between the two flanges.

[0011] A damper is installed at the other end of each of the two liquid tubes, and the end face of the damper has a plurality of large holes that communicate with the liquid tubes.

[0012] A vehicle body liquid dynamic balance stabilization system includes: a liquid compensation component, the liquid compensation component including two storage water tanks located at the bottom of the train body, the storage water tanks being filled with domestic water, the lower sides of the two storage water tanks being interconnected by multiple connectors, and a second extraction component being connected between the two storage water tanks, the second extraction component being used to extract water from one of the storage water tanks into the other storage water tank.

[0013] The second extraction component includes a double-piston rod hydraulic cylinder and multiple pipes. The upper sides of the two storage tanks are connected through the multiple pipes. The double-piston rod hydraulic cylinder is located inside the two storage tanks. Both piston rods of the double-piston rod hydraulic cylinder are connected to movable baffles. The movable baffles are slidably connected to the inner wall of the storage tank along the width direction of the storage tank.

[0014] The two storage tanks are symmetrically arranged on the left and right sides of the longitudinal axis of the train body, and multiple sets of the second extraction components are symmetrically arranged between the two storage tanks.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model discloses a liquid dynamic balance stabilization system for a vehicle body. Liquid balance replaces traditional mechanical balance. For example, in a car without a water tank, a storage tank containing a high-density liquid can be added inside the car body. Due to the faster liquid flow rate, the center of gravity can be quickly adjusted laterally to change the torque. When the car body tilts, while the liquid flows naturally, a first extraction component extracts the high-density liquid from the higher storage tank to the lower storage tank. The change in weight between the two storage tanks causes the center of gravity to shift laterally inward. By reducing weight on the unfavorable side and increasing weight on the favorable side, double the compensation torque is achieved. Simultaneously, this system can absorb vibrations during the operation of the empty rail. A connecting pipe at the lower end of the two storage tanks allows for backflow when the tanks are horizontal. Therefore, this utility model exhibits high stability and excellent compensation effect.

[0017] 2. In this utility model's liquid dynamic balance stabilization system for a train body, the stability of the train through wheel set support is stronger than that of single-point suspension support on an empty track. However, since the train track gauge is only half the width of the train, it is also more susceptible to lateral forces. For the train, it can fully utilize the large amount of domestic water storage tanks carried in each carriage to compensate for lateral forces without adding extra space. In superelevated sections, the water flows naturally from high to low through the bottom connector to compensate, and the weight of the water storage tank inside the curve is increased by the second extraction component in advance. When the train enters a windy area, the weight of the water storage tank on the windward side is increased by the second extraction component in advance to compensate. Before high-speed passing, the water storage tank is increased in advance to compensate. The second extraction component reduces the weight of the water tank on the passing side to compensate for lateral sway. By changing the weight of the water in both tanks, the second extraction component alters the lever arm and center of gravity, maximizing compensation for lateral sway caused by constant wind and reduced pressure during passing. It also helps compensate for centrifugal force when the train passes through curved sections. Therefore, with increased lateral force compensation, existing trains can reduce the superelevation of the outer rail on curved sections to reduce rail wear. Without changing the superelevation, dynamic balancing can be used for safe speed increases. By connecting the bottom of the two water tank cavities with a connector, the water flow naturally returns to its original position when the second extraction component resets, preparing for the next compensation. Therefore, this invention has high stability and good compensation effect.

[0018] 3. In this utility model's liquid dynamic balance stabilization system for a vehicle body, the storage tanks of the empty track are equipped with vents to effectively ensure equal atmospheric pressure in the left and right storage tanks, thus enabling the flow of internal liquid. The storage tanks are arranged symmetrically, so under normal circumstances, the weights and lever arms of the two storage tanks are equal, resulting in equal torque. The inclusion of inlet and outlet ports facilitates the periodic replacement of the high-density liquid. The inclusion of speed reduction plates, arranged horizontally or vertically in a staggered pattern, prevents significant fluctuations in liquid flow. The honeycomb holes on the speed reduction plates also reduce liquid sloshing within the storage tanks and minimize noise generated by sloshing. Therefore, this utility model is convenient to use and offers good stability.

[0019] 4. In this vehicle body liquid dynamic balancing stabilization system, the liquid pipes are connected via flanges and connecting bolts, allowing for convenient adjustment of the overall length of the connecting pipes and easy maintenance. A damper is installed inside the pipe, balancing compensation and backflow effects. This reduces the impact of excessive liquid backflow on the compensation effect during compensation and allows the liquid to naturally return to its initial position after compensation. Therefore, this invention is convenient to use and offers good stability.

[0020] 5. In this utility model's liquid dynamic balance stabilization system for a vehicle body, a hydraulic cylinder is added inside the water tank to push movable baffles, changing the volume of the water storage cavities on both sides. Multiple pipes are connected to the upper part of the two cavities. When the train enters a windy area or before high-speed passing, the hydraulic cylinder actuates in advance to change the volume of the two cavities, thus changing the center of gravity of the water in both cavities. When the double-piston-rod hydraulic cylinder drives the two movable baffles to move laterally to one side, the water level on one side rises and the water level on the other side falls. At this time, the center of gravity and lever arm of the water in both cavities change, achieving an initial compensation effect. When the water tank is further pushed, the water on the compressed side flows to the other cavity through multiple pipes at the top. At this time, the weight of the water in both cavities changes, resulting in a further change in lever arm and center of gravity. This change can maximize the compensation for lateral swaying caused by the reduced pressure during windy areas and passing, and can also help compensate for centrifugal force when passing through curved sections. Therefore, this utility model has high stability and good compensation effect.

[0021] 6. In this utility model's liquid dynamic balance stabilization system for a vehicle body, the communicating vessels at the bottom of the train's water tanks are arranged symmetrically, ensuring smooth backflow on both sides of the tanks. Due to the symmetrical arrangement, the weights and lever arms of the two tanks are equal, resulting in equal torques. When the vehicle body tilts, the outer tank becomes higher and the inner tank lowers. By transferring the weight of the outer tank to the inner tank, the outer tank pumps water to reduce lateral force while the inner tank adds water to increase centripetal force, achieving a double compensation for centrifugal force. This balances the lateral sway of the vehicle body. Therefore, this utility model exhibits high stability. Attached Figure Description

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] See Figure 1 and Figure 4 A vehicle body liquid dynamic balance stabilization system includes: a liquid compensation component 3, wherein the liquid compensation component 3 includes storage tanks 31 located on the left and right sides of the top of the monorail vehicle body 1, the storage tanks 31 are filled with liquid material, the lower ends of the two storage tanks 31 are connected to each other through a connecting pipe 32, and a first extraction component 35 is connected to one side of the two storage tanks 31. The first extraction component 35 is used to extract the liquid material in one of the storage tanks 31 into the other storage tank 31, and the two storage tanks 31 are symmetrically arranged on the left and right sides of the longitudinal axis of the monorail vehicle body 1.

[0033] In this embodiment, since the monorail has multiple carriages, a set of liquid compensation components 3 can be placed at the front and rear of each carriage. The storage tank 31 can be filled with liquid materials with a high specific gravity. Wind speed and direction sensors are installed at intervals on the bridge piers so that the first extraction component 35 can work in advance to change the position of the center of gravity, so that the center of gravity moves to the windward side. When the monorail car body 1 enters the right turn curve, the monorail car body 1 tilts to the left. The left storage tank 31 is raised and the right storage tank 31 is lowered. The first extraction component 35 accelerates the extraction of liquid from the left storage tank 31 to the right storage tank 31. In this way, the center of gravity moves to the right to compensate for the centrifugal force. This increase and decrease achieves the effect of doubling the balance torque. Since the torque is related to the lever arm and gravity, the center of gravity distance of the storage tanks 31 is symmetrically opened on the left and right sides along the longitudinal axis of the monorail car body 1.

[0034] Example 2:

[0035] The basic content is the same as in Example 1, except that:

[0036] See Figure 2 The first extraction component 35 includes a bidirectional pump 351 and a pipeline 352. One side of each of the two storage tanks 31 is connected to the pipeline 352. Both water inlets of the bidirectional pump 351 are connected to the pipeline 352. A vent hole 311 is provided at the upper end of each storage tank 31. A material inlet 312 is provided at the upper end of each storage tank 31. A discharge pipe 34 is connected at the lower end of each storage tank 31. Both ends of the connecting pipe 32 are connected to the sides of the two discharge pipes 34. A discharge port 313 is provided at the lower end of each discharge pipe 34. Speed ​​reduction plates 33 are spaced apart on the inner sidewall of each storage tank 31. Each speed reduction plate 33 has honeycomb holes. Multiple speed reduction plates 33 are staggered in the horizontal or vertical direction.

[0037] In this embodiment, the storage tank 31 can be set into a long strip shape with an inverted trapezoidal cross section. When the vehicle body 1 is horizontal, the liquid level of the high specific gravity liquid in the two storage tanks 31 is the same. Using a high specific gravity liquid can ensure normal flow and increase the weight of the balance body per unit volume, so as to provide a greater balancing force. At the same time, since the speed reducer 33 is arranged horizontally or vertically in an alternating manner, the liquid will not produce large fluctuations when flowing. The honeycomb holes on the speed reducer 33 can also reduce the sloshing of the liquid in the storage tank 31 and reduce the noise generated by the sloshing.

[0038] Example 3:

[0039] The basic content is the same as in Example 1, except that:

[0040] See Figure 2 and Figure 3The connecting pipe 32 includes two liquid pipes 321. One end of each liquid pipe 321 is connected to the middle of one of the two discharge pipes 34. The other ends of the two liquid pipes 321 are connected and each is connected to a flange 322 on its outer side. A connecting bolt 323 is threaded between the two flanges 322. A damper 324 is installed inside the other end of each of the two liquid pipes 321. The end face of the damper 324 has multiple large holes 325 that communicate with the liquid pipes 321.

[0041] In this embodiment, a flange 322 is welded to the end of the liquid pipe 321, and a honeycomb-shaped damper 324 is placed inside the end of the liquid pipe 321. When the vehicle body 1 is tilted, the liquid flows from one liquid pipe 321 to another liquid pipe 321, passing through the damper 324 along the way. The damper 324 can reduce the impact caused by excessive liquid flow velocity and prolong the balance effect.

[0042] Example 4:

[0043] See Figure 5 and Figure 7 A vehicle body liquid dynamic balance stabilization system includes: the liquid compensation component 3 includes two storage water tanks 37 located at the bottom of the train body 2, the storage water tanks 37 are filled with domestic water, the lower sides of the two storage water tanks 37 are connected to each other through multiple connectors 38, and a second extraction component 36 is connected between the two storage water tanks 37. The second extraction component 36 is used to extract water from one of the storage water tanks 37 into the other storage water tank 37. The two storage water tanks 37 are symmetrically arranged on the left and right sides of the longitudinal axis of the train body 2, and multiple sets of second extraction components 36 are symmetrically arranged between the two storage water tanks 37.

[0044] In this embodiment, since the train has multiple carriages, the storage water tanks 37 under each carriage can be used directly for compensation. Wind speed and direction sensors are installed at the wind vents of the train to allow the second extraction component 36 to work in advance to change the center of gravity position, causing the center of gravity to move towards the windward side. When the train body 2 enters a right turn curve, the train body 2 tilts to the left, the left storage water tank 37 lowers and the right storage water tank 37 rises. The second extraction component 36 accelerates the water from the left storage water tank 37 to the right storage water tank 37, thus shifting the center of gravity to the right to compensate for centrifugal force. This doubles the effect of increasing and decreasing the balance torque. Since the torque is related to the lever arm and gravity, the width of the two storage water tanks 37 on the left and right sides of the bottom of the train can be reduced and the height increased, thus symmetrically widening the center of gravity distance of the storage water tanks 37 along the longitudinal axis of the train body 2.

[0045] Example 5:

[0046] The basic content is the same as Example 4, except that:

[0047] See Figure 6 The second extraction component 36 includes a double piston rod hydraulic cylinder 361 and multiple pipes 362. The upper sides of the two storage tanks 37 are connected through the multiple pipes 362. The double piston rod hydraulic cylinder 361 is located inside the two storage tanks 37. The two piston rods 363 of the double piston rod hydraulic cylinder 361 are connected to movable baffles 364. The movable baffles 364 are slidably connected to the inner wall of the storage tank 37 along the width direction of the storage tank 37.

[0048] In this embodiment, a sealing ring is installed in the piston rod 363 hole on the storage tank 37 to prevent domestic water from flowing out. The diameter of the communicating vessel 38 is smaller than the diameter of the pipe 362. When the train enters the right turn curve, oil enters through the right hydraulic port of the lower double piston rod hydraulic cylinder 361 and returns through the left hydraulic port. The piston 365 moves to the left. At the same time, the water in the left storage tank 37 flows naturally to the right storage tank 37 through the communicating vessel 38. By further squeezing, the water on the left will flow to the right cavity through multiple thicker pipes 362 at the top. At this time, the weight of the water in the two cavities changes, which brings about a further change in the lever arm and center of gravity, thereby improving the effect of compensating for centrifugal force.

[0049] Although embodiments of the present invention have been shown and described above, it should be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
