Description

Technical Field

[0001] The invention relates to the technical field of hydraulic systems, in particular to a two-position four-way hydraulic flap system. Background Art

[0002] At present, steel mills use roller assembly lines and road transport to transfer hot steel billets produced by converters to rolling lines. Roller assembly line transportation requires reasonable workshop layout and production scheduling, which many domestic steel mills cannot do. Due to site limitations, they can only rely on road transport for internal transportation.

[0003] The method of road transportation is to lay rails on an open semi-trailer. The temperature of the hot billet just out of the furnace reaches 800 to 900 degrees Celsius. The hot billet is directly placed on the rails for open transportation. The driver is like sitting in a "hothouse" in the cab. When the hot billet is transported and cooled at room temperature, due to the different cooling speeds of the outside and the inside, it is easy to cause the long billet to bend at both ends and arch in the middle, causing deformation, making it difficult to unload and causing a high scrap rate of steel rolling. There is serious energy loss during transportation, resulting in a long secondary heating and steel rolling time and high energy (gas) consumption. It is imperative to manufacture vehicle insulation devices to implement insulation transportation to reduce energy consumption. Due to transportation needs, the semi-trailer pulling the hot billet is 13 meters long. The insulation device (insulation cover) weighs about 5 tons after manufacture, and about 2.5 tons when opened on one side. In order to ensure the safe and smooth opening and closing of the insulation cover, it is difficult to develop a technology that can make the insulation cover open and close smoothly.

The oil pressure interface of 322 is connected with the oil pressure gauge 323, wherein the multi-way valve group 322 is installed on the tractor, so that the power hydraulic oil flows to each component of the hydraulic oil circuit according to the corresponding channel, playing a role of on-off, the gear pump 324 is installed on the crossbeam of the tractor, connected with the transmission shaft and the tractor power take-off, and plays a role of providing power for the hydraulic system, the manual air control valve group 312 is installed at the oil outlet of the oil tank 321 to prevent the hydraulic oil in the oil tank 321 from leaking when repairing the hydraulic system, and the filter 327 is installed at the oil return port of the multi-way valve group 322 and the oil tank 321 to filter the hydraulic oil. The oil tank 321 is installed on the beam of the tractor to supply oil to the hydraulic system. The quick connector 332 plays a role in quick disassembly and replacement. The two-way balance valve 331 is installed between the multi-way valve group 322 and the telescopic cylinder 334 to control the flow of hydraulic oil so that the telescopic cylinder 334 rises and falls at a certain flow rate (telescopic action). At the same time, the two-way The balancing valve 331 has the function of locking the oil circuit at any time to prevent the automatic fall of the telescopic oil cylinder 334. The one-way throttle valve 333 is installed at the outlet of the two-way balancing valve 331 to prevent the pressure backflow of the telescopic oil cylinder 334. Specifically, 8 telescopic oil cylinders 334 are provided, and 4 are provided on the outside of the insulation half body 200 on each side to ensure the stability of the insulation half body 200 during the opening and closing process. It is worth mentioning that the oil tank 321 is installed at the corresponding positions on both sides of the tractor through the reinforcement bracket;

[0039] The manual gas control valve group 312 controls the multi-way valve group 322 through the gas pipeline;

[0040] The driving module 330 includes a two-way balancing valve 331, a quick connector 332, a one-way throttle valve 333 and a telescopic cylinder 334. The one-way throttle valve 333 and the two-way balancing valve 331 are connected to the oil inlet and outlet of the telescopic cylinder 334 through the oil pipeline. The two-way balancing valve 331 is connected to the multi-way valve group 322 through the quick connector 332. The telescopic action of the telescopic cylinder 334 is controlled by the multi-way valve group 322.

[0041] Preferably, the thermal insulation half-body 200 includes a side cover plate 210, a rear door plate 220, a front baffle plate 230, a top cover plate 240, a pressure strip 250 and a square beam 260.

The front baffle plate 230 and the rear door plate 220 are in a vertical relationship with the side cover plate 210. Only the top cover plate 240 is installed on the top of the side cover plate 210. The pressure strip is installed at the outer edge of the top cover plate 240 on any of the thermal insulation half-body 200. The pressure strip 250 is used to press the other top cover plate 240 that is not provided with the pressure strip 250 to achieve a sealing effect.

[0042] In some preferred embodiments, the square beam 260 is installed on the side of the tractor load-bearing tail compartment platform 100, the telescopic cylinder 334 is rotatably installed on the square beam 260 through a flip pin seat 270, and the output end of the telescopic cylinder 334 is rotatably connected to the outer side of the side cover plate 210 through a hinge support 280.

[0043] Furthermore, the top cover plate 240 and the side cover plate 210 form an angle of 93°, in order to form a certain slope on the top surface, so as to ensure that rainwater can flow down the slope and not accumulate on the top during the rainy season, further ensuring the heat preservation during transportation to prevent heat loss and prevent rainwater from seeping in. The side cover plate 210, rear door plate 220, front baffle plate 230 and top cover plate 240 are steel plates with a thickness of 5 mm. In order to ensure the stability of the structure of the heat-insulating half-body 200, a plurality of square steels and channel steels are also provided on the side cover plate 210, rear door plate 220, front baffle plate 230 and top cover plate 240 for reinforcement.

[0046] After the heat preservation structure 400 is set, when you put your hand close to the "heat preservation box", you can feel the warmth of your hand, without the burning sensation of the hot billet at 600 to 700 degrees Celsius. The temperature difference of the hot billet varies between 100 and 200 degrees Celsius, which reduces the production energy consumption cost of the enterprise, achieves cost reduction and efficiency creation, and improves the operating efficiency of the enterprise.

[0047] In some preferred embodiments, the thermal insulation cotton fixing bracket 410 is composed of multiple flat irons, steel bars, and channel steels. The flat irons and channel steels are welded on the inner walls of the side cover plate 210, the rear door plate 220, the front baffle plate 230, and the top cover plate 240 at different intervals to form a fixed bracket for installing the thermal insulation cotton 420. The thermal insulation cotton 420 is then filled into the area circled by the thermal insulation cotton fixing bracket 410. The thermal insulation barrier formed by the thermal insulation cotton 420 can "lock" the temperature of the hot steel billet well, ensuring that the hot steel billet will not be deformed due to uneven heating and cooling during transportation, and will not increase the energy consumed by secondary heating due to excessive heat dissipation.

[0048] When in use, turn on the power take-off switch on the tractor, the power take-off drives the gear pump 324 to start working, operate the manual air control valve group 312, the multi-way valve group 322 starts working, and the hydraulic oil enters the telescopic cylinder 334 through the two-way balance valve 331 and the one-way throttle valve 333. The telescopic action of the telescopic cylinder 334 drives the thermal insulation half-body 200 to perform a smooth opening and closing action.

[0049] In summary, the system utilizes the linkage mode of air-controlled liquid to ensure the smooth opening and closing of the insulation half-box, and an insulation structure is also provided in the insulation half-box to ensure that the temperature loss can be reduced during transportation.
