Description

Technical Field

[0001] The present invention relates to the technical field of single-rail hoist locomotives, and particularly to an extended-range explosion-proof diesel single-rail hoist locomotive. Background Art

[0002] With the increasing requirements for the exhaust emissions of diesel single-rail hoist locomotives in coal mine safety production, coal mine operators have gradually replaced diesel single-rail hoist locomotives with lithium battery single-rail hoist locomotives. However, due to the limitation of battery capacity, lithium battery single-rail hoist locomotives have poor endurance and long charging time, which cannot meet the normal working needs.

[0003] In the existing technical solutions, in order to ensure that the battery endurance can meet the daily work tasks of the work team, usually the number of lithium batteries is increased or a battery replacement station is built in the charging chamber. In the former case, the excessive number of lithium batteries increases the length and weight of the locomotive, affecting the load-bearing capacity of the locomotive, and does not effectively shorten the charging time; in the latter case, the cost is relatively high, and it also takes time to replace the battery.

For example, when using light-load short-distance transportation for a long time, the extended-range mode can be turned off and driven purely electrically.

When starting with normal full charge, the range extender component 4 does not work. The whole machine is first powered by the first explosion-proof lithium battery 31. When the power of the first explosion-proof lithium battery 31 is lower than 10%, the output voltage of the first explosion-proof lithium battery 31 gradually decreases and stops discharging, and the second explosion-proof lithium battery 31 intervenes to supply power. At this time, the range extender component 4 starts to work, the explosion-proof diesel engine 41 starts to run, drives the explosion-proof permanent magnet generator 44 to work, and the generated power is completely supplied to the first explosion-proof lithium battery 31. When the first explosion-proof lithium battery 31 is fully charged, the explosion-proof diesel engine 41 stops working. When the power of the second explosion-proof lithium battery 31 is lower than 10%, it stops discharging, and the first explosion-proof lithium battery 31 intervenes to supply power, and the range extender component 4 starts to supplement the endurance for the second explosion-proof lithium battery 31;

[0072] The explosion-proof lithium battery 31 is used for supplying power to the driving part 2;

[0073] The battery management module 32 is used for coordinating the charging and discharging of the explosion-proof lithium battery 31;

[0077] An accumulator 36 for storing and releasing the hydraulic oil pressure energy.

[0078] The range extender assembly 4 includes an explosion-proof diesel engine 41, a cooling fan 42, a diesel fuel tank 43, an explosion-proof permanent magnet generator 44, and an exhaust gas treatment tank 45;

[0079] The explosion-proof diesel engine 41 is used to drive the explosion-proof permanent magnet generator 44 to generate electricity;

[0080] The cooling fan 42 is used for cooling the explosion-proof diesel engine 41;

[0081] The diesel fuel tank 43 is used for supplying fuel to the explosion-proof diesel engine 41;

[0082] The explosion-proof permanent magnet generator 44 is used to convert mechanical energy into electrical energy;

[0083] The exhaust gas treatment tank 45 is used for purifying the exhaust gas of the explosion-proof diesel engine 41.

[0084] The electric energy of the explosion-proof permanent magnet generator 44 is stored inside the explosion-proof lithium battery 31 in cooperation with the battery management module 32.

[0085] The fixing assembly 14 includes a base 141, a T-shaped frame 143, and a strap 144. The base 141 is installed at the rear side of the cab 1. The T-shaped frame 143 is fixedly connected to the top of the base 141. One end of the strap 144 is hinged to one side of the T-shaped frame 143. The other end of the strap 144 is fixedly connected with a connecting block 147. A limiting groove 148 is opened on one side of the connecting block 147. A slot 1413 is opened on one side of the T-shaped frame 143. A limiting component is arranged on the other side of the T-shaped frame 143. A rubber pad 142 is arranged at the inner bottom of the base 141. A rubber plate 145 is installed on the inner side of the strap 144. An arc-shaped elastic pad 146 is installed on one side of the T-shaped frame 143. When installing the fire extinguisher 15, by placing the fire extinguisher 15 inside the base 141, the rubber pad 142 can provide support for the fire extinguisher 15. Then, insert the connecting block 147 at one end of the strap 144 into the inside of the slot 1413. At this time, the rubber plate 145 abuts against the outer side of the fire extinguisher 15. At the same time, the fire extinguisher 15 presses the arc-shaped elastic pad 146 to deform, completing the fixation of the fire extinguisher 15, and can prevent the fire extinguisher 15 from shaking and colliding during the running of the locomotive, thus affecting the service life of the fire extinguisher 15.

[0086] The limiting component includes a pulling block 149, a stop block 1411 and a telescopic spring 1412. The stop block 1411 is fixedly connected to the other side of the T-shaped frame 143. A guide rod movably penetrates through the stop block 1411. The outer side of the guide rod is movably sleeved with the telescopic spring 1412. One end of the telescopic spring 1412 is fixedly connected to one side of the stop block 1411, and the other end of the telescopic spring 1412 is fixedly connected to one side of the pulling block 149. The pulling block 149 is fixedly connected to one end of the guide rod. One end of the pulling block 149 is provided with an inclined surface 1410. When the fire extinguisher 15 needs to be used, by pulling the pulling block 149 outwards to move on one side of the T-shaped frame 143, the pulling block 149 moves on the outer side of the guide rod to compress the telescopic spring 1412. One end of the pulling block 149 disengages from the inside of the limiting groove 148. At this time, under the action of the rebounding force of the arc-shaped elastic pad 146, the arc-shaped elastic pad 146 pushes the fire extinguisher 15 to move, so that the binding strap 144 drives the connecting block 147 to disengage from the inside of the slot 1413, and the restraint of the fire extinguisher 15 can be quickly completed, so that the personnel can take the fire extinguisher 15 in time for use, preventing the delay of the fire situation and causing more losses.

[0087] During the process of inserting the connecting block 147 into the inside of the slot 1413, the connecting block 147 abuts against the inclined surface 1410 of the pulling block 149, thereby pushing the pulling block 149 to move on the outer side of the guide rod. At this time, the telescopic spring 1412 is compressed by force. When one end of the pulling block 149 moves to the outside of the limiting groove 148, the telescopic spring 1412 pushes one end of the pulling block 149 to insert into the inside of the limiting groove 148, and then the fixation of the position of the connecting block 147 is completed.
