Description

Technical Field

[0001] The utility model belongs to the technical field of electric flat cars, in particular to a power supply device for a rail electric flat car. Background Art

[0002] Electric flat car, also known as electric flatbed car, level car, trolley, cross-car, electric rail car, ground crawler, etc., is a kind of rail-type electric transport vehicle within the factory. First of all, it is a rail-type transport vehicle, which requires laying tracks on the ground. The tracks are generally I-shaped surface contact rails; secondly, it is an electric drive vehicle, which runs automatically under the drive of the motor reducer; thirdly, it is a flatbed car with a flat table and no cover. Under special circumstances, it can also be non-flat but without a cover. The car body has no steering wheel and only forward and backward directions. This type of vehicle has the characteristics of simple structure, easy use, large carrying capacity, not afraid of dirt or smashing, easy maintenance, and long service life. Due to its convenience, sturdiness, economy, practicality, easy cleaning and many other advantages, it has become the preferred means of transportation for frequent short-distance fixed-point transportation of heavy objects within the factory building and between factories.

[0003] Track power supply for electric flat cars is a common power supply method, also known as "third rail power supply" or "contact line power supply". Specifically, this power supply method is to lay conductive rails or wires next to or under the track to transmit electrical energy to the contact device (such as the collector shoe) on the electric flat car to provide power.

[0004] After searching, the announcement number CN207630986U and the announcement date 2018-07-20 disclose a special power supply device for a low-voltage rail-powered electric flat car, which includes a movable guide arm, a guide arm base, a grinding block base, an insulating plate and a grinding block. The guide arm base is fixed on the body of the low-voltage rail electric flat car; the upper end of the movable guide arm is rotatably connected to the guide arm base through a horizontal guide arm shaft perpendicular to the conductive rail of the electric flat car, and the lower end is fixedly connected to the grinding block base; the grinding block is pressed on the conductive rail and fixedly connected to the grinding block base through an insulating plate, and the grinding block is connected to the step-up transformer on the electric flat car through a wire. The grinding block of the utility model is connected to the body of the electric flat car through a movable guide arm. When the surface of the conductive rail is uneven, the impact of the raised part on the grinding block can be reduced by a small swing of the movable guide arm, thereby reducing the failure rate of the power supply device, improving the operating reliability of the power supply device, and ensuring the normal operation of the electric flat car.

[0005] This patent has the following deficiencies:

[0006] 1. The power taking device adopts single point contact, the contact area between the grinding block and the conductive rail is small, the supply current is relatively concentrated, the contact resistance between the grinding block and the conductive rail is large, the wear is serious, and the power supply of the electric flat car is not stable enough;

[0007] 2. The flexible design of the power taking device is not ideal, and it is difficult to adapt to the changes and vibrations of the conductive rail, which easily leads to contact interruption. Utility Model Content

[0009] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0010] The utility model is a power-taking device for a rail electric flat car, comprising a top power-taking component, a side power-taking component, a frame and a connecting plate.

[0012] Furthermore, two ends of the first spring are fixedly connected to the base plate and the fixing plate respectively, and two ends of the second spring are fixedly connected to the fixing plate and the limiting block respectively.

[0013] Furthermore, the frame is fixed to the top of the fixing plate through four supporting legs.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model sets a top power-taking component and two side power-taking components, and the multi-point contact design makes the contact area of ​​the grinding block larger. By increasing the number of contact points, the current can be dispersed and the contact effect can be improved, reducing contact resistance and wear.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] See also Figures 1-2As shown, the utility model is a rail electric flat car power supply device, including a top power supply component 1, a side power supply component 2, a frame 4 and a connecting plate 5. The top power supply component 1 is located at the top surface of the I-shaped conductive rail 3, and two side power supply components 2 are provided, which are symmetrically distributed on both sides of the I-shaped conductive rail 3; the top power supply component 1 is fixed to the bottom of the frame 4, the frame 4 is fixed to the bottom of the car body 6, the side power supply component 2 is fixed to one end of the connecting plate 5, and the other end of the connecting plate 5 is fixed to the frame 4.

[0029] The multi-point contact design of the top power-taking component 1 and the two side power-taking components 2 makes the contact area of ​​the grinding power block 11 larger. By increasing the number of contact points, the current can be dispersed and the contact effect can be improved, reducing contact resistance and wear. The power supply of the electric flat car is more stable, and the side power-taking component 2 also plays a limiting role, so that the electric flat car can run more smoothly on the I-shaped conductive rail 3.

[0030] Among them Figure 3 As shown, the top power-taking assembly 1 includes a grinding power block 11, a base plate 12, a buffer rod 13, a fixed plate 14, a limit block 15, a first spring 16 and a second spring 17; the grinding power block 11 is fixed to the bottom of the base plate 12, and four buffer rods 13 distributed in a matrix are fixed to the top of the base plate 12. The buffer rods 13 are movable through the fixed plate 14, and the top of the buffer rods 13 is fixed with the limit block 15; the first spring 16 is sleeved on the buffer rod 13 between the base plate 12 and the fixed plate 14, and the second spring 17 is sleeved on the buffer rod 13 between the fixed plate 14 and the limit block 15.

[0031] The arrangement of the buffer rod 13, the fixing plate 14, the first spring 16 and the second spring 17 makes the top power-taking assembly 1 and the side power-taking assembly 2 elastic, so that they can adapt to the changes and vibrations of the I-shaped conductive rail 3. Increasing the elasticity of the grinding block 11 can improve the contact stability and reduce the contact interruption caused by the deformation or vibration of the I-shaped conductive rail 3; when the I-shaped conductive rail 3 vibrates, the grinding block 11 rises and falls with the I-shaped conductive rail 3, and consumes energy through the first spring 16 and the second spring 17.

[0032] The structure of the side power-taking assembly 2 is the same as that of the top power-taking assembly 1 . The grinding power block 11 of the top power-taking assembly 1 abuts against the top surface of the I-shaped conductive rail 3 ; the grinding power block 11 of the side power-taking assembly 2 abuts against the side surface of the I-shaped conductive rail 3 .

The provision of the slot 51 allows the position of the connecting plate 5 on the frame 4 to be adjusted, thereby adjusting the pressure between the side power extraction assembly 2 and the I-shaped conductive rail 3, thereby adapting to the use of I-shaped conductive rails 3 of different specifications.
