Abstract
Description
Technical Field
[0001] The present invention relates to the field of engineering equipment, and particularly to a new type of current collector. Background Art
[0002] Mobile devices (mainly elevators, construction hoists, cranes, overhead traveling cranes, derricks, etc.) need to constantly change their positions due to movement. At each different position, the mobile device must be able to obtain a power supply at any time, otherwise it cannot continue to move. At this time, the sliding contact wire came into being. A number of conductors are laid parallel to the running track of the mobile device, and the power supply is connected. On the moving device, a current collector that can draw electricity from the conductors is installed. In this way, when the device moves, the current collector runs synchronously with the device and obtains power from the conductors at any time to supply the device so that the device can continue to move. Usually, a current collector contacts the sliding contact wire on the mobile device, and the power on the sliding contact wire is supplied to the electrical equipment through the current collector. However, the existing current collectors have complex structures and are prone to short circuits during operation, which is not safe. Summary of the Invention
[0003] The present invention provides a new type of current collector to solve the problems in the prior art.
[0004] The object of the present invention is achieved by the following technical solutions:
[0005] A new type of current collector includes a carbon brush box, a fixing frame, and an indicator light assembly. Both the carbon brush box and the indicator light assembly are connected to the fixing frame. Taking the direction in which the carbon brush box slides as the main view plane, the carbon brush is provided with five-phase carbon brushes, namely: phase A carbon brush, phase B carbon brush, phase C carbon brush, phase D carbon brush, and phase E carbon brush. The phase A carbon brush and the phase B carbon brush are located on the top surface of the carbon brush box. The phase C carbon brush and the phase D carbon brush are located on the bottom surface of the carbon brush box. The phase E carbon brush is located on the side surface of the carbon brush box.
[0006] The above-mentioned new current collector is mainly applicable to be used in conjunction with a five-phase sliding contact wire. During use, the carbon brush box slides within the sliding contact wire groove. The carbon brushes on the carbon brush box come into contact with the conductive grooves of the sliding contact wire. The five phases of the above-mentioned current collector include phase A, phase B, phase C, phase D, and phase E. Among them, three phases are connected to the live wire, one phase is connected to the neutral wire, and another phase is connected to the ground wire. Among them, phase E is the ground wire. In the front view of the sliding direction of the carbon brush box, the carbon brushes of phase A and phase B are arranged on the top surface of the carbon brush box and are located at the diagonals of the top surface. The carbon brushes of phase C and phase D are located on the bottom surface of the carbon brush box and are at the diagonals of the bottom surface. More preferably, the two-phase carbon brushes at the same end of the carbon brush box are located at the diagonals of the front view. With such a setting, when used in conjunction with the sliding contact wire, the carbon brushes in two adjacent conductive grooves of the sliding contact wire are located on the top surface and the bottom surface of the carbon brush box, or at the front end and the rear end of the carbon brush box, and the two adjacent carbon brushes are arranged at intervals. In this way, the carbon powder generated during the operation of the carbon brushes will not come into contact, thus avoiding the problem of short circuit.
[0007] Preferably, the carbon brush box includes outer shells that cover each other, and a wiring groove is arranged inside the outer shells; four wiring grooves are arranged, and symmetrically arranged on both sides of the symmetry axis with the midline of the long side of the outer shell as the symmetry axis; conductive members are arranged in the wiring grooves, and the conductive members are connected to the carbon brushes.
[0008] The carbon brush box is composed of two mutually buckled outer shells, and the structure is simple. Multiple wiring grooves are formed inside the buckled outer shells, and the length direction of the wiring grooves is the same as the length direction of the carbon brush box. Conductive members are arranged in the wiring grooves. The conductive members preferably use copper wires, and the elastic ends are divided into two branches, and each branch is connected to a carbon brush. One carbon brush is composed of two copper sheets.
[0009] Preferably, the outer shell is provided with a hollowed-out groove; the carbon brush is arranged in the hollowed-out groove.
[0010] The outer shell is provided with a hollowed-out groove, and the carbon brush protrudes from the inside of the carbon brush box to the outside of the carbon brush box through the hollowed-out groove. And the top end of the carbon brush is higher than the surface of the carbon brush box.
[0011] Preferably, the carbon brush is provided with a spring, one end of the spring abuts against the outer shell, and the other end abuts against the carbon brush.
[0012] The carbon brush is provided with a carbon brush, one end of the spring abuts against the outer shell, and the other end abuts against the carbon brush. When the carbon brush comes into contact with the sliding contact wire, the carbon brush is extruded more tightly with the conductive groove of the sliding contact wire.
[0013] Preferably, one end of the conductive member is connected to the carbon brush; the other end is provided with a power connection hole; the power connection hole is connected to an external wire. One end of the conductive member is provided with a power connection hole, and the power connection holes of multiple conductive members converge at an edge of the carbon brush box, and then the external wire is connected to the power connection hole through a bolt, thereby playing a role in conducting electricity.
[0014] Preferably, guide wheel assemblies are provided at both ends in the sliding direction of the carbon brush box.
[0015] Preferably, the guide wheel group includes a fixed block and rollers; the fixed block is connected to the carbon brush box, and rollers are provided on four side surfaces of the fixed block.
[0016] A guide wheel assembly is provided on the carbon brush box. The guide wheel assembly is provided with a fixed block, and the cross-sectional size of the fixed block is the same as that of the cross-section of the carbon brush box. Rollers are provided around the fixed block. In this way, the carbon brush box will not rub against the outer shell of the sliding contact wire during the sliding process, and the service life of the current collector and the sliding contact wire can be extended.
[0017] Preferably, a wiper is provided on the carbon brush box.
[0018] During the use process, due to reasons such as temperature and air pressure, water vapor may be formed inside the sliding contact wire. The water vapor forms water droplets on the inner wall of the sliding contact wire, and the accumulation of water droplets may cause a short circuit. A wiper is provided at one end of the carbon brush box. During the movement of the carbon brush box, the water droplets on the inner wall of the sliding contact wire are scraped off by the wiper.
[0019] Preferably, the wiper includes a water guide box, and the water guide box is provided with a wiper blade; a drain hole is provided at the bottom of the water guide box.
[0020] The wiper blade provided on the water guide box contacts the inner wall of the outer shell of the sliding contact wire at the edge during the use process. During the sliding process of the carbon brush box, the formed water droplets are scraped into the water guide box, and finally discharged from the sliding contact wire through the drain hole and the drain pipe connected to the drain hole.
[0021] Compared with the prior art, the present invention has the following technical effects:
[0022] A novel current collector provided by the present invention adopts a five-phase segmentation setting method, and adjacent two phases are arranged on opposite surfaces of the carbon brush box or at both ends of the carbon brush box, thereby avoiding the problem of short circuit caused by carbon powder generated during the use process. In addition, the current collector of the present invention adopts an outer shell arranged oppositely and a wiring method inside the outer shell, with a simple structure and convenient assembly. Finally, guide wheel groups and wipers are provided at both ends of the carbon brush box, which improves the service life of the equipment and further provides the safety of use.
