Description

Technical Field

[0001] The present application relates to the technical field of power transmission of mobile equipment, and in particular to an antifreeze device for busbars of a coke quenching vehicle. Background Art

[0002] Mobile equipment needs to change positions constantly due to mobile operations. At each different position, the mobile equipment must be able to obtain power at any time, otherwise it will not be able to move further. Busbars, also known as trolley wires, are a group of power transmission devices that supply power to mobile equipment (such as quenching vehicles). A collector contacts the busbar on the mobile equipment, so that the power on the busbar is provided to the mobile equipment through the collector.

[0003] During the coking production process in the northern winter, the coke in the quenching car will release a large amount of water vapor after being quenched and quickly cooled down by the quenching tower. The water vapor will easily freeze on the surface of the busbar of the quenching car. The freezing will cause poor contact between the busbar and the collector of the quenching car, resulting in reduced traction, failure and shutdown of the quenching car, affecting the normal operation of the quenching car and posing a safety risk.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0029] like Figure 1 and Figure 3 As shown, the present application provides a quenching car busbar antifreeze device, comprising: a busbar 1, a heating structure 2, a fixing structure 3, an insulating structure 4 and a condensate collector 5.

[0030] The heating structure 2 includes a steam pipe 210, a steam distributor 220 and a heating pipe 230. An insulating structure 4 is connected between the steam distributor 220 and the heating pipe 230, and between the heating pipe 230 and the condensate collector 5. The output end of the steam pipe 210 is connected to the inlet of the steam distributor 220, and the outlet of the steam distributor 220 is connected to multiple heating pipes 230 through the insulating structure 4. The heating pipe 230 is in parallel contact with one side of the busbar 1 through the fixed structure 3, and the output end of the heating pipe 230 is connected to the condensate collector 5 through the insulating structure 4.

[0031] Specifically, the busbar 1 is used to provide power to the quenching car. The heating structure 2 provides heat to the busbar 1 to prevent the busbar 1 from freezing in a low temperature environment, which would result in poor contact between the busbar 1 and the quenching car. Therefore, the setting of the heating structure 2 helps the busbar 1 to always maintain contact with the quenching car, so that the busbar 1 can continuously supply power to the quenching car, which is beneficial to the stable operation of the quenching car. The fixing structure 3 is used to detachably connect the heating structure 2 to the busbar 1, so that the heating structure 2 maintains contact with the busbar 1, so that the heating structure 2 can continuously and stably supply heat to the busbar 1 and prevent the busbar 1 from freezing.

[0032] The heating structure 2 includes a steam pipe 210, a steam distributor 220 and a heat tracing pipe 230. The steam pipe 210 is connected to the steam network of the factory to provide heat for the heating structure 2. The steam distributor 220 is used to distribute the steam from the steam pipe 210 to each heat tracing pipe 230. The heat tracing pipe 230 is arranged in parallel with the busbar 1. During operation, the heat of the steam in the heat tracing pipe 230 is transferred to the busbar 1 through the wall of the heat tracing pipe 230, so that the temperature of the busbar 1 rises. When the coke in the quenching car is rapidly cooled by the quenching tower, a large amount of water vapor is generated. When the water vapor is scattered on the surface of the busbar 1, even if the external ambient temperature is low, due to the heating of the heat tracing pipe 230, the temperature of the busbar 1 surface rises, which is not enough to make the water vapor freeze on the busbar 1 surface. In this way, the busbar 1 surface is not frozen, which can ensure that the quenching car always maintains good contact with the busbar 1 during movement, so that the quenching car can operate safely and stably.

[0033] When the steam flows in the heating pipe 230 , it exchanges heat with the surface of the busbar 1 , which will produce condensed water. Finally, the condensed water flows through the outlet of the heating pipe 230 to the inside of the condensate collector 5 for collection.

[0034] The insulating structure 4 is used to insulate the steam distributor 220, the condensate collector 5 and the heating pipe 230. Because there is a certain voltage on the busbar 1, the heating pipe 230 may be conductive when in contact with the busbar 1. This arrangement prevents the steam distributor 220 and the condensate collector 5 from being conductive, avoids the risk of personnel and other equipment being conductive, and improves the safety of the operating environment.

[0035] The present application realizes the antifreeze of the busbar of the quenching car at low temperature through the above scheme. A heating structure is set to provide heat to the busbar to prevent the busbar from freezing in a low temperature environment. The heating structure includes a steam pipe, a steam distributor and a heating pipe. The heating pipe is arranged in parallel contact with the busbar. During operation, the heat of the steam in the heating pipe is transferred to the busbar through the wall of the heating pipe, so that when water vapor is scattered to the surface of the busbar, due to the temperature rise of the busbar, the surface of the busbar is not enough to make the water vapor freeze on the surface of the busbar. It can ensure that the quenching car always maintains good contact with the busbar during movement, so that the quenching car can operate safely and stably. The insulating structure prevents the conduction of the steam distributor and the condensate collector, avoids the risk of personnel and other equipment being conducted, and improves the safety of the operating environment.

[0036] like Figure 2 As shown, optionally, a steam regulating valve 221 is provided at the outlet of the steam distributor 220 .

[0037] Specifically, the steam regulating valve 221 is used to adjust the amount of steam entering the heating pipe 230 from the steam distributor 220 to ensure heat exchange between the heating pipe 230 and the busbar 1, so that the temperature of the surface of the busbar 1 is not high enough to cause the water vapor to freeze, thereby ensuring good contact between the busbar 1 and the quenching car.

[0038] At the same time, the steam volume can be increased or decreased according to weather conditions, which saves steam consumption and ensures the normal operation of the busbar 1, thereby effectively improving the anti-icing effect and reliability of the busbar 1 and ensuring the normal operation of the quenching car.

[0039] like Figure 2 As shown, optionally, the insulation structure 4 includes a first insulation tube 410 and a second insulation tube 420, and both ends of the first insulation tube 410 are respectively connected to the outlet of the steam distributor 220 and the inlet of the heating pipe 230, and both ends of the second insulation tube 420 are respectively connected to the outlet of the heating pipe 230 and the inlet of the condensate collector 5.

[0040] Specifically, since there is a certain voltage on the busbar 1, the heating pipe 230 may be conductive when in contact with the busbar 1, and the water vapor of the steam distributor 220 is transported to the heating pipe 230 through the first insulating pipe 410, and the condensate at the outlet of the heating pipe 230 is transported to the condensate collector 5 through the second insulating pipe 420. This arrangement avoids conductivity of the steam distributor 220 and the condensate collector 5, and also avoids the risk of conductivity to personnel and other equipment, thereby improving the safety of the operating environment.

[0041] like Figure 3 As shown, optionally, the fixing structure 3 includes a U-shaped fixing clamp 310 , a bolt 320 and a nut 330 .

[0042] The cross-sections of the heating pipe 230 and the busbar 1 are embedded in the U-shaped fixing clamp 310. The heating pipe 230 and the busbar 1 pass through the U-shaped fixing clamp 310 in parallel. The bolt 320 passes through the opposite side plates of the U-shaped fixing clamp 310 in sequence. One end of the bolt 320 is connected to a nut 330. The bolt 320 is located between the bottom of the heating pipe 230 and the busbar 1 and the bottom inside the U-shaped fixing clamp 310.

[0043] Specifically, the heating pipe 230 is arranged on one side of the busbar 1. As water vapor is passed into the heating pipe 230, the heating pipe 230 has a certain weight. The fixed structures 3 are arranged at equal distances so that the heating structure 2 maintains parallel contact with the busbar 1.

[0044] The U-shaped fixing clamp 310 is located at the bottom of the heating pipe 230 and the busbar 1. The heating pipe 230 and the busbar 1 pass through the U-shaped fixing clamp 310 in parallel. The opposite sides of the U-shaped fixing clamp 310 are fastened to the heating pipe 230 and the busbar 1 by bolts 320 and nuts 330, so that the heating pipe 230 and the busbar 1 maintain contact, thereby allowing the heating structure 2 to continuously and stably supply heat to the busbar 1 to prevent the busbar 1 from freezing.

[0045] like Figure 4 As shown, in another feasible method, one end of the bolt 320 passes through the U-shaped fixing clamp 310 close to any side plate of the heating pipe 230 or the busbar 1, and abuts against the side wall of the heating pipe 230 or the busbar 1, and the other end of the bolt 320 is connected with the nut 330, and the bottom of the heating pipe 230 and the busbar 1 are in direct contact with the bottom of the U-shaped fixing clamp 310. By rotating the nut 330, a side plate of the U-shaped fixing clamp 310 and one end of the bolt 320 are used to tighten or loosen the heating pipe 230 and the busbar 1, making it more convenient to tighten the heating pipe 230 and the busbar 1.

[0046] Furthermore, a gasket (such as a rubber gasket) is provided at one end of the bolt 320 that contacts the heating pipe 230 or the busbar 1 to prevent the bolt 320 from damaging the outer side of the heating pipe 230 or the busbar 1 .

[0047] like Figure 5 As shown, optionally, the U-shaped fixing clamp 310 is composed of two L-shaped plates 311, wherein the bottom plates of the two L-shaped plates 311 are sleeved and connected.

[0048] Specifically, the bottom plates of the two L-shaped plates 311 are sleeved and connected to form a U-shaped fixing clamp 310, so that the width of the U-shaped fixing clamp 310 can be adjusted according to the size of the cross-section of the heating pipe 230 and the busbar 1, making the applicability of the U-shaped fixing clamp 310 wider. When fixing, the bolts 320 pass through the side walls of the two L-shaped plates 311 in sequence to fix the two L-shaped plates 311 to each other, thereby achieving the purpose of fixing the heating pipe 230 and the busbar 1 in the two L-shaped plates 311.

[0049] like Figure 2 and Figure 6 As shown, optionally, the bottom of the busbar 1 is connected to the supporting column 7 through the insulator 6, and the top of the busbar 1 is connected to the current collector 8.

[0050] Specifically, the bottom of the busbar 1 is connected to the support column 7 through the insulator 6. The support column 7 supports and fixes the busbar 1, making the busbar 1 more stable, thereby making the contact between the busbar 1 and the heating pipe 230 more stable. The top of the busbar 1 is connected to the current collector 8, which is also connected to the quenching car. The current collector 8 is used to transmit the electric energy of the busbar 1 to the quenching car to provide electric energy for the mobile operation of the quenching car. The support of the support column 7 helps the stable connection between the current collector 8 and the busbar 1 and the quenching car, which is beneficial to the stable operation of the quenching car.

[0051] The busbar 1 is connected to the supporting column 7 via the insulator 6, which prevents the supporting column 7 from conducting electricity, avoids the occurrence of electric shock accidents, and further improves the safety of the site.

[0052] The insulator 6 is a glass insulator or a ceramic insulator. The cross-sectional area of ​​the heat tracing pipe 230 is greater than, equal to or less than the cross-sectional area of ​​the busbar 1, as long as the stable contact between the collector 8 and the busbar 1 is ensured.

[0053] Optionally, a gas outlet 510 is provided at the top of the condensate collector 5 , and a liquid outlet 520 is provided at the bottom of the condensate collector 5 .

[0054] Specifically, the steam exchanges heat with the surface of the busbar 1 while flowing in the heat tracing pipe 230, which will produce condensed water, and finally a mixture of condensed water and water vapor is obtained through the outlet of the heat tracing pipe 230, and flows into the condensate collector 5, the water vapor is discharged from the gas outlet 510, and the condensate is discharged from the liquid outlet 520. That is, the purpose of collecting the condensate is achieved, and the gas outlet 510 can also keep the pressure in the condensate collector 5 stable.

[0055] The technical solution of the present application is described in detail below with reference to specific embodiments.

[0056] The operation flow of the busbar antifreeze device of the quenching car in this embodiment is as follows:

[0057] The steam pipe 210 is connected to the steam network of the factory to provide heat for the heating structure 2. The steam from the steam pipe 210 enters the steam distributor 220 and is distributed to each of the first insulating pipes 410 and flows through the heating pipe 230. The heating pipe 230 is arranged in parallel with the busbar 1. During operation, the heat of the steam in the heating pipe 230 is transferred to the busbar 1 through the wall of the heating pipe 230, so that the temperature of the busbar 1 rises. When the coke in the quenching car is rapidly cooled by the quenching tower, a large amount of water vapor is generated. When the water vapor is scattered on the surface of the busbar 1, even if the external ambient temperature is low, due to the heating of the heating pipe 230, the temperature of the busbar 1 surface rises, which is not enough to make the water vapor freeze on the busbar 1 surface, so as to achieve the purpose of antifreeze of the busbar 1. While the steam flows in the heating pipe 230 , it exchanges heat with the surface of the busbar 1 , producing condensed water. Finally, a mixture of condensed water and water vapor is obtained through the outlet of the heating pipe 230 , and flows into the condensate collector 5 through the second insulating pipe 420 . The water vapor is discharged from the gas outlet 510 , and the condensate is discharged from the liquid outlet 520 .

[0058] The bottom of the busbar 1 is connected to the support column 7 through the insulator 6, the heating pipe 230 and the busbar 1 are parallelly passed through the U-shaped fixing clamp 310, and the opposite sides of the U-shaped fixing clamp 310 are fastened to the heating pipe 230 and the busbar 1 through the bolts 320 and the nuts 330, so that the heating pipe 230 and the busbar 1 are kept in contact. The top of the busbar 1 is connected to the collector 8, which is also connected to the quenching car, and transmits the electric energy of the busbar 1 to the quenching car, so as to continuously provide electric energy for the mobile operation of the quenching car.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
