Description

Technical Field

[0001] The utility model relates to the technical field of rail trolleys, in particular to a magnetic charging system for rail trolleys. Background Art

[0002] At present, the movement of the rail trolley is achieved by walking back and forth on a specific track. Among them, the rail trolley is equipped with a drive motor. After the drive motor is powered, it can drive the wheels to rotate, thereby realizing the movement of the rail trolley. The traditional way of taking power is to use cables for power. However, in this way of taking power, the cable will be dragged during the movement of the rail trolley. When the rail trolley travels back and forth for a long time, the cable will be constantly bent back and forth; at the same time, when the cable is dragged, the cable will also scratch the ground or other obstacles, causing the cable to wear more seriously.

[0003] In order to avoid the inconvenience caused by the above-mentioned cable power supply method, technicians began to use the track power supply method to realize the power supply of the rail trolley. Specifically, the track power supply method is to transmit the current to the track, and use the brushes set on the rail trolley to contact the conductive track to realize power supply. For example, some rail trolleys are equipped with three brushes, and the three brushes are respectively connected to the conductive sub-track, power signal sub-track and control signal sub-track on the track to realize the power supply and communication functions of the rail trolley. However, during use, the inventor found that this power supply method also has the following disadvantages:

[0004] (1) During the long-term operation of the rail trolley, due to processing and assembly problems, and considering the soft material of the brush, the brush will be severely worn, and the staff needs to periodically inspect, repair or replace the brush;

[0005] (2) When using brushes, the biggest problem is still the intermittent power supply. In other words, when the carbon brushes as brushes slide against the conductive sub-tracks, the contact between the brushes and the conductive sub-tracks is actually intermittent due to the elastic force of the compression spring and the machining accuracy of the conductive sub-track surface. When the brushes are separated from the conductive sub-tracks, the rail trolley may be interrupted due to a momentary power outage.

[0006] In summary, when the rail trolley uses the rail power supply, the brushes on it will wear out quickly and the contact will be unstable during the long-term operation of the rail trolley, which will make it impossible for the rail trolley to obtain power stably for a long time. To this end, we propose a magnetic power supply system for rail trolleys to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problems in the prior art and to propose a magnetic power-taking system for a rail trolley. Compared with the power-taking method using brushes in the prior art, the magnetic power-taking method in the power-taking system can achieve long-term and stable power taking for the rail trolley.

[0008] In order to solve the above problems, the utility model provides the following technical solutions:

[0009] A magnetic power-attracting system for a rail trolley comprises: a rail trolley and a conductive magnet magnetically attracted to a rail device, wherein the conductive magnet and a power component on the rail trolley are connected to each other via a flexible bridge, so that when the rail trolley generates a guided movement along the rail device, power is supplied by relying on the magnetic attraction of the conductive magnet relative to the rail device and the flexible distance compensation and dragging effect of the flexible bridge.

[0010] As a further solution of the utility model: the flexible bridge includes a conductive wire with a steel wire arranged inside, and two ends of the conductive wire are electrically connected to the power component and the conductive magnet respectively.

[0011] As a further solution of the utility model: the track device is configured as a parallel double-track type, and two conductive magnets are configured. The two conductive magnets are respectively arranged on both sides of the track trolley and are respectively magnetically attracted to one of the tracks of the track device, and an isolation plate located between the double tracks of the track device is fixedly arranged at the bottom of the track trolley, and the isolation plate is used to prevent the magnetic flux lines of the two conductive magnets from interfering with each other.

[0012] As a further solution of the utility model: a power connection bolt is provided on the rail trolley, the power component is connected to the top of the power connection bolt through an upper wire, and the conductive magnet is connected to the bottom of the power connection bolt through a conductive wire.

[0013] As a further solution of the utility model: the rail trolley is provided with an insulating protective cover for covering both ends of the power connection bolts, and the top and bottom of the insulating protective cover are respectively provided with gaps for the upper conductor and the conductive wire to pass through.

[0014] As a further solution of the utility model: the other end of the conductive wire is fixedly connected to the conductive magnet by a fastening bolt.

[0015] As a further solution of the utility model: the power component includes a single chip microcomputer.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The utility model provides a power-drawing method that cooperates with a flexible bridge and a conductive magnet. Compared with the prior art method of using cables and brushes to draw power, it can achieve stable power-drawing between the rail trolley and the rail device. Moreover, with the flexible distance compensation and dragging effect of the flexible bridge, even if the rail trolley is traveling on a track section with a large turning angle or an uneven track section of the rail device, the distance compensation and the adsorption of the conductive magnet can be used to make the conductive magnet always slide and adsorb on the rail device stably, thereby achieving a good power supply effect. Of course, compared with soft brushes, conductive magnets are less prone to wear and have a longer service life. The maintenance cycle can also be appropriately extended, thereby further improving the cost-effectiveness of conductive magnets. I will not go into details here.

[0018] 2. By setting the flexible bridge as a conductive wire with steel wire inside, the conductive wire can electrically connect the power component and the conductive magnet on the one hand, and can also achieve flexible distance compensation and dragging of the conductive magnet on the other hand, so that the conductive magnet can move with the track trolley;

[0019] 3. Through the setting of the partition, on the basis of setting the track device as a parallel double track and setting two conductive magnets, the isolation plate is used to separate the two conductive magnets so that the magnetic flux lines of the two conductive magnets do not interfere with each other, ensuring that the two conductive magnets can work normally.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 2As shown, a magnetic power-absorbing system for a rail trolley includes: a rail trolley 1 and a conductive magnet 3 magnetically attracted to a rail device 2, wherein the conductive magnet 3 and a power component 4 on the rail trolley 1 are connected to each other via a flexible bridge 5, so that when the rail trolley 1 generates a guided movement along the rail device 2, power is supplied by the magnetic attraction of the conductive magnet 3 relative to the rail device 2 and the flexible distance compensation and dragging action of the flexible bridge 5. The utility model provides a power-absorbing method in which the flexible bridge 5 and the conductive magnet 3 cooperate, which can minimize the wear caused by long-term power-absorbing, and can achieve long-term stable power-absorbing operation of the rail trolley 1, compared with the cable power-absorbing method and the brush power-absorbing method in the prior art.

[0026] Regarding the setting of the above-mentioned flexible bridge 5, the flexible bridge 5 includes a conductive wire with steel wire inside, and the two ends of the conductive wire are electrically connected to the power component 4 and the conductive magnet 3 respectively. At the same time, the track device 2 is set as a parallel double-track type, and two conductive magnets 3 are set. The two conductive magnets 3 are respectively set on both sides of the track trolley 1 and are magnetically attracted to one of the tracks of the track device 2, and the bottom of the track trolley 1 is fixedly provided with an isolation plate 6 located between the two tracks of the track device 2, and the isolation plate 6 is used to prevent the magnetic flux lines of the two conductive magnets 3 from interfering with each other.

[0027] On the basis of setting two conductive magnets 3, both rails of the track device 2 can be electrified, so that a closed loop is formed between the two rails of the track device 2, the two conductive magnets 3 and the power component 4. Under the closed action of this loop, the power component 4 will be energized, and then the track trolley 1 can be controlled to move. During the movement, since the power component 4 is magnetically connected to the two rails of the track device 2 through the conductive magnets 3, the conductive magnets 3 will not be worn to a large extent during the long-term operation of the track trolley 1. At the same time, under the action of the conductive magnets 3 and the flexible bridge 5, even if the track trolley 1 is traveling on a track section with a large bending angle of the track device 2, the conductive magnets 3 can be stably slid and adsorbed on the track device 2.

[0028] Regarding the configuration in which the flexible bridge 5 is configured as a conductive wire, the conductive wire configured here can, on the one hand, serve to electrically connect the power component 4 and the conductive magnet 3, and on the other hand, serve to flexibly and flexibly connect the power component 4 and the conductive magnet 3, so that during the adsorption and sliding process of the conductive magnet 3 on the track device 2, it can be adaptively adjusted according to the bending angle of the track device 2, etc., thereby ensuring the stability of the adsorption and sliding of the conductive magnet 3.

[0029] It should be noted that this embodiment is not limited to setting the flexible bridge 5 as a conductive wire, and the flexible bridge 5 can also be set as an elastic member in the prior art, such as a conductive spring, as long as the flexible bridge 5 can achieve the corresponding flexibility compensation function.

[0030] like Figure 1 As shown, further, on the basis of setting the track device 2 as a parallel double-track type, two conductive magnets 3 are respectively arranged on both sides of the track trolley 1. In order to prevent the two conductive magnets 3 from interfering with each other, an isolation plate 6 located between the two tracks of the track device 2 can be fixedly arranged at the bottom of the track trolley 1. The isolation plate 6 is used to prevent the magnetic flux lines of the two conductive magnets 3 from interfering with each other. Of course, the two conductive magnets 3 can also be arranged at one end of the track trolley 1 away from each other to achieve the purpose of preventing the magnetic flux lines of the two conductive magnets 3 from interfering with each other.

[0031] On the basis of setting the flexible bridge 5 as a conductive wire, a power connection bolt 7 can be provided on the rail trolley 1, the power component 4 is connected to the top of the power connection bolt 7 through the upper wire, and the conductive magnet 3 is connected to the bottom of the power connection bolt 7 through the conductive wire. Further, in order to protect the power connection bolt 7, an insulating protective cover 8 for covering both ends of the power connection bolt 7 can be provided on the rail trolley 1, and the top and bottom of the insulating protective cover 8 are respectively provided with gaps for the upper wire and the conductive wire to pass through.

[0032] Regarding the setting of the above-mentioned middle track device 2, wherein:

[0033] The track device 2 includes an insulating base track 202 and a magnetic power-collecting track 201 arranged on the insulating base track 202. The magnetic power-collecting track 201 and the insulating base track 202 are both arranged as two parallel tracks. Two conductive magnets 3 are magnetically arranged on the two tracks of the magnetic power-collecting track 201, respectively, so that a closed loop is formed between the two tracks of the magnetic power-collecting track 201, the two conductive magnets 3 and the power component 4, so that the power component 4 is energized. When the power component 4 is energized, the track trolley 1 can be controlled to move. Furthermore, the track trolley 1 can be assembled on the magnetic power-collecting track 201 or the insulating base track 202, Figure 1 and Figure 2 The figure shows the situation where the rail trolley 1 is assembled on the magnetic power rail 201, but there is no restriction on the assembly and travel path of the rail trolley 1.

[0034] Specifically, the power component 4 can be any suitable computing device, such as a personal computer, a server, a programmable controller (PLC controller for short), a single-chip microcomputer, etc., or it can be an integration of computer devices. The power component 4 has functions such as receiving information and sending control commands. The power component 4 can control the rail trolley 1 to perform corresponding moving actions through wired communication or wireless communication.

[0035] like Figure 2 As shown, for the setting of the above-mentioned track trolley 1, the track trolley 1 is provided with four wheels 10 and a drive motor 9 for driving the wheels 10 to rotate, and the drive motor 9 is electrically connected to the power component 4; then after the power component 4 is energized, the drive motor 9 can be controlled to work, and the forward and reverse rotation of the output shaft of the drive motor 9 can realize the forward and backward movements of the track trolley 1.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
