A self-unloading tail discharge feeding trolley

Abstract

The invention relates to a self-unloading tail feeding trolley, which comprises a vehicle body and a walking wheel set. The walking wheel set includes a front wheel and a rear wheel. The track of the front wheel is greater than that of the rear wheel. Bearing seat, the bearing seat is connected with the front wheel, the rear part of the vehicle body is provided with a discharge port, the rear part of the vehicle body is connected with a rotatable tail panel, and the body and the rear panel can form an included angle of 0-90 degrees, so A rear wheel support plate is connected between the tail cover and the rear wheel. The present invention adopts the tail discharge method. The front wheel and the rear wheel adopt different wheelbases and run on different tracks. During operation, it can automatically close and open the discharge port to realize automatic unloading, without lifting the tail of the trolley for unloading, which reduces the power of the winch and reduces the space occupied during unloading. In addition, during the unloading process , The tail mask can prevent dust from spreading and reduce environmental pollution.

Description

technical field [0001] The invention relates to a feeding trolley for inclined bridges, in particular to a self-unloading tail feeding trolley. Background technique [0002] At present, the feeding car used in the inclined bridge feeding system is a forward-leaning head discharge method. The working mode is that when the feeding car reaches the unloading point, the front wheels are forced to stop, and at this time the hoist continues to pull the wire rope to make the rear of the feeding car Lift it up, dump the material at the designated place, then reverse the winch, and slowly lower the rear of the feeding car, so that the wheels fall back to the track to complete a feeding process. There are many problems in the forward-leaning head discharge method. First, The power ratio of the hoist is relatively high, and the energy consumption is high. When reaching the unloading point, the front wheels of the feeding car are forced to stop. Before this, the four wheels were rolling ...

Problems solved by technology

[0002] At present, the feeding car used in the inclined bridge feeding system is a forward-leaning head discharge method. The working mode is that when the feeding car reaches the unloading point, the front wheels are forced to stop, and at this time the hoist continues to pull the wire rope to make the rear of the feeding car Lift it up, dump the material at the designated place, then reverse the winch, and slowly lower the rear of the feeding car, so that the wheels fall back to the track to complete a feeding process. There are many problems in the forward-leaning head discharge method. First, The power ratio of the hoist is relatively high, and the energy consumption is high. When reaching the unloading point, the front wheels of the feeding car are forced to stop. Before this, the four wheels were rolling on the track. After the front wheels were blocked, they needed to be replaced. Only a large pulling force can lift the rear of the trolley; secondly, the space requirements are relatively high. When adding powdery materials, the material in the trolley needs to be dumped at least at an elevation angle of 70-80 degrees. Therefore, above the feeding point, at least Leave a space equal to the length of the vehicle body, and in some places, the space is occupied by some pipes, steel beams, etc., and it is difficult to free up more space; third, the dust is large and the environmental pollution is serious. When feeding and unloading the trolley, If the unloading car and the feeding port are pasted too close, the head of the trolley will be stuck in the feeding port when the rear of the trolley is lifted, so a certain space should be left so that a closed space cannot be formed when feeding, and the dust will spread and pollute the environment; Fourth, there are potential safety hazards. After the rear of the car is lifted and unloaded, the rear wheels need to fall back on the track, but the lack of guiding devices is prone to deviation
