As shown in fig. 4, 5 and 6, at present, all the centering cylinders 5 in the industry are positioned below the large bracket 4, and the centering cylinders 5 realize the left-right rotation centering of the current collecting system by pushing the central vertical shaft 6. However, the total height of the collector system is high, the trolley bus needs to pass through a culvert under special operation conditions, and the collector system is excessively high and can scratch the culvert and the like.

Disclosure of Invention

The utility model aims to solve the technical problems that: how to reduce the height of the collector system and to realize the centering control of the collector bar, therefore, a centering control device of the collector system is provided.

The technical scheme of the utility model is as follows:

the utility model provides a control device in back of current collection system which characterized in that: comprises a rotating body arranged on the upper part of a large bracket, and a bearing is arranged on the rotating body; the upper part of the large bracket is provided with a left middle return cylinder and a right middle return cylinder, and output shafts of the left middle return cylinder and the right middle return cylinder are hinged on the rotating body; the left middle return cylinder is a middle return cylinder of the left trolley pole, and the right middle return cylinder is a middle return cylinder of the right trolley pole; and the left middle return air cylinder and the right middle return air cylinder comprise two air cylinders which are arranged in a back-to-back mode.

The left middle return cylinder is connected with a fifth electromagnetic valve, and the right middle return cylinder is connected with a sixth electromagnetic valve; the fifth electromagnetic valve and the sixth electromagnetic valve are both positioned in the pneumatic control box and are both connected with the air storage tank.

The beneficial effects of the utility model are as follows: the centering cylinder pushes the rotating body to replace pushing the vertical shaft, so that the centering function is realized, the height of the current collecting system can be effectively reduced, and the culvert is prevented from being scratched.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 7, 8 and 9, a centering control device of a current collecting system comprises a rotating body 8 arranged on the upper part of a large bracket 4, wherein a rotating bearing is arranged on the rotating body 8; and a left middle return cylinder 9 and a right middle return cylinder 10 are arranged at the upper part of the large bracket 4, and the output shafts of the left middle return cylinder 9 and the right middle return cylinder 10 are hinged on the rotating body 8.

The left middle return cylinder 9 is a middle return cylinder of a left trolley pole, and the right middle return cylinder 10 is a middle return cylinder of a right trolley pole. And, the left middle return cylinder 9 and the right middle return cylinder 10 each include two cylinders arranged in a back-to-back manner.

That is, the left middle cylinder 9, the right middle cylinder 10 and the trolley pole 1 are located on the same side with respect to the large bracket 4.

The two middle returning cylinders are in a back-to-back mode, when the current collecting system hangs a net, the middle returning cylinders are in a free state, the current collecting system swings along with the net, and when the trolley pole 1 swings right, the middle returning cylinders are contracted; when the trolley pole 1 swings leftwards, the middle returning cylinder is pushed out; when the net is removed, the single-side centering cylinder is in a contracted state and is in a push-out state, so that the trolley pole can be pushed to the centering state. And then lowering the rod into the collector hook. It should be noted that, the lifting cylinder and the principle thereof for placing the trolley pole into the collector hook assembly 3 are the prior art, and are not described in detail in the present utility model.

According to the utility model, the two centering cylinders are lifted to the upper part of the large bracket 4 from the bottom of the large bracket 4, so that the rotating cylinder pushes the upper rotating body 8 to perform centering, and the original central vertical shaft is omitted, thereby greatly reducing the overall height.

Further, as shown in fig. 10, the left middle cylinder 9 is connected with the fifth electromagnetic valve K5, the right middle cylinder 10 is connected with the sixth electromagnetic valve K6, the original left slow descending cylinder is connected with the first electromagnetic valve K1, the right slow descending cylinder is connected with the second electromagnetic valve K2, the left fast descending cylinder is connected with the third electromagnetic valve K3, the right fast descending cylinder is connected with the fourth electromagnetic valve K4, the right hooking cylinder is connected with the seventh electromagnetic valve K7, the left hooking cylinder is connected with the zeroth electromagnetic valve K0, the first electromagnetic valve K1, the second electromagnetic valve K2, the third electromagnetic valve K3, the fourth electromagnetic valve K4, the fifth electromagnetic valve K5, the sixth electromagnetic valve K6, the seventh electromagnetic valve K7 and the zeroth electromagnetic valve K0 are all located in the pneumatic control box, and the electromagnetic valves are all connected with the air storage tank.

As shown in fig. 11, the third solenoid valve K3 and the fourth solenoid valve K4 are opened, and quick lowering into the collector hook is performed; opening a fifth electromagnetic valve K5 and a sixth electromagnetic valve K6, and centering a trolley pole; then, after a delay of 6s, the first solenoid valve K1 and the second solenoid valve K2 are opened, and slow lowering into the collector hook is performed.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several changes and modifications can be made without departing from the general inventive concept, and these should also be regarded as the scope of the utility model.
