TECHNICAL FIELD
[0001] The utility model relates to the technical field of trolley line deicing, especially to a snow melting and deicing device for trolley line of coke oven electric locomotive. BACKGROUND
[0002] The coke industry electric locomotive runs on the coke quenching car track of the coke side of the coke oven, and is used for traction and control of coke tank cars or wet coke quenching cars. The electric locomotive is an important equipment for transporting red coke, and its running frequency is high, speed is fast, and route is long, and most of its power supply devices adopt the trolley line form. In winter in some areas, due to low temperature and snow weather, the trolley line is often covered with ice or snow, and the contact with the current collector is poor, which causes the electric locomotive to have power failure when running. Due to the fast speed, the stability and safety of the electric locomotive running are seriously affected. SUMMARY
[0003] The utility model discloses a snow melting and deicing device for trolley line of coke oven electric locomotive, which aims to solve the problem of ice and snow accumulation on the trolley line of the electric locomotive in winter, and ensure the stable operation of the electric locomotive.
[0004] Technical scheme: To achieve the above-mentioned purpose, the utility model discloses a snow melting and deicing device for trolley line of coke oven electric locomotive, which comprises an electric locomotive carrying coke tanks and a trolley line supplying power to the electric locomotive. A fan is provided on the electric locomotive, and the air inlet end of the fan is located above the coke tank. A heat collecting mechanism is provided at the air inlet end of the fan. The air outlet end of the fan faces the trolley line, so that the fan can send the collected heat to the vicinity of the trolley line.
[0005] Further, the heat collecting mechanism comprises a heat collecting hood, which is located above the coke tank and connected to the fan through an air inlet pipeline.
[0006] Further, the heat collecting hood is retractable, and can be extended to cover directly above the coke tank or retracted to be staggered with the coke tank.
[0007] Further, an electric push rod is installed on the electric locomotive and connected to the heat collecting hood, so that the heat collecting hood can be actively extended and retracted.
[0008] Further, an air outlet pipeline is connected to the fan, and the air outlet end of the air outlet pipeline branches into several branches. Each branch is provided with a heat injection port, and each heat injection port faces a trolley line.
[0009] Further, the heat injection port is spaced apart from the trolley line, and the heat injection port gradually expands along the air outlet direction.
[0010] The snow melting and deicing device for trolley line of coke oven electric locomotive has the following beneficial effects:
[0011] 1) Since the coke canisters on the locomotive contain red-hot coke, a fan is installed on the locomotive to transfer the heat generated by the red-hot coke to the area around the sliding contact line in order to remove snow or ice from the sliding contact line.
[0012] 2) The fan collects heat through the air inlet pipe and the heat collection hood. The heat collection hood is telescopic. When the heat collection hood is extended to the top of the coke can, it can collect heat. When the heat collection tube is retracted to be offset from the coke can, it will not affect the loading and unloading of red coke in the coke can. Attached Figure Description
[0013] Appendix Fig. 1 A schematic diagram of the fan and heat collector on the locomotive;
[0014] Appendix Fig. 2 This is a schematic diagram showing the heat nozzle and the sliding contact line facing each other. Detailed Implementation
[0015] The present invention will be further described below with reference to the accompanying drawings.
[0016] As attached Figs. 1-2 The aforementioned snow-melting and de-icing device for the sliding contact line of a coke oven locomotive includes a locomotive 4 carrying a coke canister 11 and a sliding contact line 8 supplying power to the locomotive 4. The coke canister 11 of the locomotive 4 carries red-hot coke, which typically has a temperature of around 1050°C. Therefore, the heat generated by the red-hot coke can be used to clear the ice and snow on the sliding contact line 8.
[0017] Specifically, a fan 5 is installed on the locomotive 4. The air inlet of the fan 5 is located above the coke tank 11, and a heat collection mechanism is provided at the air inlet of the fan 5. When the fan 5 is started, it can collect the hot air above the coke tank 11, thereby generating hot air. The air outlet of the fan 5 faces the sliding contact line 8, so that the fan 5 can send the collected heat to the vicinity of the sliding contact line 8, that is, blow hot air towards the sliding contact line 8 to clear the ice or snow accumulated on the sliding contact line 8.
[0018] The heat collection mechanism includes a heat collection hood 1, which is located above the coke tank 11. One side of the heat collection hood 1 is connected to the air inlet pipe 2, and the heat collection hood 1 is connected to the fan 5 through the air inlet pipe 2. Through the heat collection hood 1, the heat of the red coke in the coke tank 11 can be collected better.
[0019] The heat collection cover 1 is retractable, and one embodiment includes, for example, an attached... Fig. 1 As shown, an electric push rod 3 is installed on the electric locomotive 4. The electric push rod 3 is connected to the heat collection hood 1, allowing the heat collection hood 1 to extend and retract actively. The heat collection hood 1 can extend to cover directly above the coke tank 11 to collect heat; the heat collection hood 1 can retract to be offset from the coke tank 11 to avoid the heat collection hood 1 interfering with the loading and unloading of red coke inside the coke tank 11.
[0020] The fan 5 is connected with an air outlet pipeline 6, as shown in the accompanying Fig. 1 and 2 The outlet side of the fan 5 is connected with the air outlet pipeline 6, and the air outlet end of the air outlet pipeline 6 is branched into several branches, and each branch is provided with a heat spout 7. Fig. 2 As shown in the accompanying drawings, the slide wire 8 has a plurality of slide wires, and the slide wire 8 is installed on the bracket 10 through the insulator 9. Each heat spout 7 is directed to each slide wire 8. The heat spout 7 is spaced apart from the slide wire 8 to avoid direct contact with the slide wire 8, and the heat spout 7 is gradually expanded in the air outlet direction, so that the coverage of the hot air spouted by the heat spout 7 is larger.
[0021] The working mode of the utility model is as follows: when the red coke is loaded in the coke tank 11 on the electric locomotive 4, the fan 5 is started, and the heat collecting cover 1 is controlled to extend through the electric push rod 3, the fan 5 collects the heat of the red coke through the air inlet pipeline 2 and the heat collecting cover 1, and then spouts hot air towards the slide wire 8 through the air outlet pipeline 6 and the heat spout 7, so as to clean the accumulated ice or snow on the slide wire 8.
[0022] Compared with the prior art, the utility model can effectively utilize the heat generated by the red coke to solve the problem in winter, and compared with the existing electric heating method, the energy consumption can be effectively saved and the cost can be reduced. In addition, all the components in the utility model are on the electric locomotive 4, and any heating equipment does not need to be installed on the long slide wire 8, and the existing electric heating installed on the slide wire 8 often deforms in a large range due to high temperature, which causes line grounding tripping, and the snow melting and ice removing device of the utility model can effectively reduce the maintenance cost and difficulty.
[0023] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model.
