Description
Technical Field
[0001] The utility model relates to the field of logistics automatic transportation, in particular to an EMS driving unit with high-power contactless power supply. Background Art
[0002] With the change of modern enterprise production and operation modes and the change of external market conditions, the space for reducing product costs by reducing raw material costs and conducting product technology development is getting smaller and smaller. The traditional self-sufficient logistics service cannot compare with professional third-party logistics enterprises in terms of economic benefits, systematization and specialization. This makes more and more enterprises outsource logistics services that do not belong to the core competitiveness of the enterprise in order to optimize enterprise resource allocation and enhance market competitiveness, promoting the rapid development of Chinese third-party logistics. The EMS trolley with contactless power supply is an EMS trolley that drives the motor to move by means of wireless power supply of a current collector. Since it does not require contact components such as brushes, it avoids the unstable power supply caused by the wear of the contact components.
[0003] At present, affected by the conversion efficiency, the power of the current collector is often not large enough, which causes problems such as too low running speed or even inability to run when traveling on a sloped track or carrying a large load. Therefore, it is necessary to improve such a structure to overcome the above defects. Summary of the Utility Model

[0007] A further setting of the present utility model is that the main power collector and the auxiliary power collector are arranged on the same side of the track.
[0008] In the above technical solution: the main power collector and the auxiliary power collector are arranged on the same side of the track so that both of them can use the same power supply cable at the same time.

[0010] In the above technical solution: the limiting wheel is in contact with the track, so that the limiting wheel can play a limiting role.
[0011] A further setting of the present utility model is that the driving wheel remains in contact with the upper end surface of the track.
[0012] In the above technical solution: the driving wheel remains in contact with the upper end surface of the track, so that the driving wheel can always realize the movement of the present utility model by friction with the track.
[0013] A further setting of the present utility model is that it further includes a switch, and the switch is electrically connected to the main power collector and the auxiliary power collector.
[0014] In the above technical solution: the setting of the switch enables the connection of the auxiliary power collector to be disconnected on the flat section, thereby avoiding the motor running at a low load and high power for a long time.
[0015] The present utility model discloses an EMS driving unit with high-power contactless power supply. Compared with the prior art:
[0016] 1. By setting the main power collector and the auxiliary power collector, the present utility model can provide the input power of the motor through the additional power supply of the auxiliary power collector on the slope section, thereby increasing the output power of the motor so as to maintain the running speed of the present utility model on the slope section or under high load.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] The following is a detailed description of the embodiments of the present utility model. The embodiments are implemented on the premise of the technical solution of the present utility model, and detailed implementation manners and specific operation processes are given. However, the protection scope of the present utility model is not limited to the following embodiments.
[0023] As Figures 1-3 shown, an EMS drive unit for high-power contactless power supply proposed by the present utility model includes a main frame 10, and also includes a drive assembly 20, a main power taker 30 and a secondary power taker 40. The drive assembly 20 includes a second frame 201, a drive wheel 202, a motor 203 and a plurality of limit wheels 204. The motor 203 is fixedly arranged on the second frame 201. The drive wheel 202 is fixedly connected to the output end of the motor 203, and the rotation axis of the drive wheel 202 is horizontal. The limit wheel 204 is rotatably connected to the second frame 201, and the rotation axis of the limit wheel 204 is vertical. A connecting frame 205 is also fixedly arranged on the second frame 201. The main power taker 30 and the secondary power taker 40 are both fixedly arranged on the connecting frame 205, and the main power taker 30 and the secondary power taker 40 are arranged at intervals and are disconnectably connected in series. Among them, the number of the drive assemblies 20 is two, and the two drive assemblies 20 are arranged at intervals, so that the present utility model operates stably; the main power taker 30 is electrically connected to the motor 203; the number of the limit wheels 204 included in each drive assembly 20 is at least four, two of the limit wheels 204 are arranged on the upper side, and two of the limit wheels 204 are arranged on the lower side; preferably, a second limit wheel is arranged on the connecting frame 205.
[0024] AsFigures 1-3 As shown, for an EMS drive unit with high-power contactless power supply proposed by the present utility model, the main current collector 30 and the auxiliary current collector 40 are arranged on the same side of the track.
[0025] As Figures 1-3 shown, for an EMS drive unit with high-power contactless power supply proposed by the present utility model, the limit wheel 204 remains in contact with the track for the movement of the transport trolley. Among them, the track is in the shape of "I".
[0026] As Figures 1-3 shown, for an EMS drive unit with high-power contactless power supply proposed by the present utility model, the drive wheel 202 remains in contact with the upper end surface of the track. Among them, the shape of the second frame is "C", so that it is adapted to the track.

Among them, the switch can be connected to an infrared sensor. By arranging infrared emission devices at the track before the slope section and in the slope section, when the infrared sensor receives the first infrared ray, it emits a signal to make the switch connected.

[0028] The working principle of the present utility model is as follows:
[0029] a) When on a flat section, only the main current collector supplies power, and the motor operates at a lower power;
[0030] b) When approaching the uphill section, a signal is transmitted to the switch to make the switch connected;
[0031] c) The auxiliary current collector is also connected to the motor, so that the input power of the motor increases, and thus the output power of the motor increases; d) The rotational speed of the drive wheel increases, so that the moving speed of the trolley increases;
[0032] e) The initial speed is higher when going uphill;
[0033] f) It can travel at a relatively fast speed when going uphill;
[0034] g) When returning to the flat section, a signal is transmitted to the switch again to make the switch disconnected;
[0035] h) The auxiliary current collector is also disconnected from the motor.
