In the following, with reference to specific embodiments, a detailed description is given of how the trolley pole is controlled by the wire-bonding control system to perform the neutralization and swing functions, so that a person skilled in the art can fully understand the design thought of the technical scheme.
Example 1
The first wire-lapping control system for the trolley pole comprises a gas source, wherein the gas source is usually supplied by a vehicle, the gas source is connected by a gas pipe, a return system 2 and a swing system 1 are connected at the end part of the gas pipe, wherein the return system 2 is connected with the swing system 1 in parallel, namely a branch pipe I and a branch pipe II are formed from the end part of the gas pipe, the return system 2 is arranged on the branch pipe I, the swing system 1 is mainly arranged on the branch pipe II, and the gas flow of the swing system 1 is integrated into the return system 2.

The first air inlet selector valve 202 is connected with two pipelines, namely a first air passage and a second air passage, and the first air passage and the second air passage are both connected with a rodless cavity of an air cylinder.
The second air inlet selector valve 203 is connected with two pipelines, namely a third air passage and a fourth air passage, and the third air passage and the fourth air passage are both connected with a rodless cavity of the cylinder.
Here, we take the cylinder group as an example, which is formed by two cylinders (a first cylinder and a second cylinder) connected in a back-to-back way, wherein the first cylinder and the second cylinder are respectively provided with a rod cavity and a rodless cavity, one side of the rodless cavity is close to the other side of the rodless cavity, one side of the rod cavity is far away from the other side of the rod cavity, a first air passage on the first air inlet selector valve 202 is connected to the rodless cavity of the second cylinder, and a second air passage is connected to the rodless cavity of the first cylinder; a third air passage on the second air inlet selector valve 203 is connected to the rod cavity on the first cylinder, and a fourth air passage is connected to the rod cavity on the second cylinder.

The air pipe is communicated with an air source on the vehicle, air flow enters the electromagnetic valve group through the air pipe, when the electromagnetic valve group is powered on, the air flow enters the first air inlet selection valve 202 through the first pipeline, the second pipeline enters the second air inlet selection valve 203, air flows to the air cylinders from the second air passage and the fourth air passage respectively, as the second air passage is connected to the rodless cavity of the first air cylinder, the fourth air passage is connected to the rod cavity of the second air cylinder, in the ventilation state, the second air passage and the fourth air passage are simultaneously powered on, the area of the rodless cavity of the first air cylinder can be maximized, meanwhile, the area of the rod cavity of the second air cylinder is minimized, at the moment, the added travel distance of the first air cylinder and the second air cylinder just reaches the intermediate value of the maximum travel distance and the minimum travel distance of the first air cylinder and the second air cylinder, and the electric collecting pole is just above the roof at the moment.
When the electromagnetic valve group is powered off, the electromagnetic valve group cuts off the air flow entering the first pipeline and the second pipeline.
It can be seen that the solenoid valve group functions to control the intake air of the first intake air selector valve 202 and the second intake air selector valve 203, and the first intake air selector valve 202 and the second intake air selector valve 203 can secondarily distribute the air flow on the branch air paths to which they belong.

Here, it should be noted that, the selection of the third pipeline and the fourth pipeline access end is specific to different cylinders, specifically, taking this embodiment as an example, the cylinder group is composed of a first cylinder and a second cylinder that are connected in a back-to-back manner, as described above, the first air path on the first air intake selector valve 202 in the return system 2 is connected to the rodless cavity of the first cylinder, and the second air path is connected to the rodless cavity of the second cylinder; the third air passage on the second air inlet selector valve 203 is connected to the rod cavity on the first cylinder, the fourth air passage is connected to the rod cavity on the second cylinder, and the connection mode of the swinging system 1 and the centering system 2 is as follows:

or if the third pipeline in the swinging system 1 is integrated on the fourth pipeline, the fourth pipeline can only be integrated on the second pipeline;
or if the third pipeline in the swinging system 1 is integrated on the first pipeline, the fourth pipeline can only be integrated on the third pipeline;
or if the third pipeline in the swinging system 1 is integrated on the second pipeline, the fourth pipeline can only be integrated on the fourth pipeline;
that is, the third line is incorporated into the rod-cavity or rodless-cavity inlet air path of one cylinder, and the fourth line is incorporated into the rod-cavity or rodless-cavity inlet air path of the other cylinder.
In the following, according to the actual working condition, how the control system realizes the centering and swinging of the trolley pole is described in detail, when the vehicle needs to acquire electric energy from the wire net, the trolley pole is lifted to a certain height, and at this time, when the vehicle is not at the position right below the wire net or is at the position far away from the wire net, the trolley pole cannot be enabled to realize the contact with the wire net by the vertical lifting of the trolley pole in the prior art, so as to be described in the background art, the vehicle usually has to be stopped below the wire net, the position of the vehicle is fixed, the accurate positioning requirement on the vehicle in the actual working condition is extremely high, the requirement on the driver is higher, and once slightly deviated from the stopping area, the driver is required to manually pull the trolley pole to the roof to realize the contact with the wire net.
The following describes in detail how the trolley pole touch is implemented in a vehicle in case of a deviated wire mesh, assuming the wire mesh is at the upper left of the vehicle, the trolley pole is first lifted vertically in the manner known from the prior art, after reaching the level together, the gas source is then switched on, the gas entering the solenoid valve in the return system 2 and the first solenoid control valve 101 in the rocking system 1.

Under the normal condition, when the trolley pole is positioned right above a vehicle, the area of a pole cavity of one cylinder is the largest, and the area of a pole-free cavity is the smallest; the rod-containing area of the other cylinder is the smallest, the rod-free area is the largest, and in this embodiment, for better explanation, it is assumed that the rod-containing area of the first cylinder is the largest, and the rod-free area is the smallest; the area of the rod cavity of the second cylinder is minimum, and the area of the rodless cavity is maximum.
Because the wire net is positioned at the left side of the trolley pole and the trolley pole is required to swing leftwards, at the moment, the first electromagnetic control valve 101 distributes air flow to the third pipeline, the tail end of the third pipeline is connected to the rod cavity of the first air cylinder due to the fact that the tail end of the third pipeline is connected to the third pipeline, and the area of the rod cavity of the first air cylinder can be gradually increased by filling air into the rod cavity of the first air cylinder, so that the piston rod of the first air cylinder 3 is retracted; part of the gas in the third gas path flows upwards and flows into the second gas inlet selection valve 203, flows out of the fourth gas path and enters the rod cavity of the second cylinder 4, so that the area of the rod cavity of the second cylinder is increased, the area of the rod-free cavity is reduced, and the piston rod can pull the trolley pole to swing leftwards.
Assuming that the wire net is positioned at the upper right part of the vehicle, when the trolley pole is required to swing rightwards, the first electromagnetic control valve 101 distributes air flow to the fourth pipeline, the tail end of the fourth pipeline is integrated to the first pipeline, and as the first pipeline is connected to the rodless cavity of the second cylinder, the area of the rodless cavity can be gradually increased by filling air into the rodless cavity of the second cylinder, so that the piston rod of the second cylinder is prolonged; some of the gas input to the first gas path through the fourth pipeline flows along the first gas path to the first gas inlet selector valve 202, flows out of the second gas path and flows into the rodless cavity of the first cylinder, so that the rodless cavity area of the first cylinder is increased, the rod cavity area is reduced, the piston rod of the first cylinder is extended, and the trolley pole is pulled to swing rightward.
Indeed, the control modes of the two swinging systems 1 are only the methods adopted by one connecting mode of the swinging system 1 and the centering system 2, and based on the four connecting modes of the swinging system 1 and the centering system 2 described in the foregoing, corresponding methods can be formed on the premise of adopting the ideas, so as to realize the control of the horizontal swinging of the trolley pole.
Through the technical scheme, the wire-bonding control system provided by the embodiment has lower requirements on the position parking of the vehicle and the wire net particularly when being applied to the trolley pole, a driver does not need to get off the vehicle to assist wire bonding, and the trolley pole can correspondingly swing through intelligent operation to realize automatic wire bonding operation; meanwhile, in the off-net state, the centering system 2 can ensure accurate centering.
