Description

Technical Field

[0001] This utility model relates to the field of guide bell mouth, and particularly to a guide bell mouth device for current collectors. Background Technology

[0002] The guide bell-shaped device is an important component of the conductor rail system, mainly used to guide the current collector smoothly into and out of the guide rail, ensuring the continuity and stability of power transmission. It is used in lifting machinery such as electric hoists and overhead cranes.

[0003] While traditional guide bell devices can provide guidance for current collectors, they lack a dedicated power supply wiring design, requiring the search for a separate location to set up a power access point, which is very inconvenient in design and construction. At the same time, when the guide bell device is connected to the duct-type sliding contact line, it is fixed by plugging the side interface into the port of the sliding contact line, lacking other limiting designs, resulting in poor stability of the connection between the guide bell device and the sliding contact line. Utility Model Content

[0018] The aforementioned guide flare device for current collectors features a dedicated power supply wiring structure, integrating guidance and power supply into one, eliminating the need for a separate location for the power supply access structure. Furthermore, the copper conductor is extended from the conduit-type sliding contact line into the conductor slot inside the flare. After the copper conductor is laid in the conductor slot, it is flush with the guide slot wall, ensuring smooth entry and exit of the current collector. This eliminates steps that could cause wear on the current collector, reducing current collector losses and increasing its lifespan. Even further, a positioning mechanism is added. After the guide flare device is inserted into the end of the sliding contact line, the positioning mechanism positions and limits the connection, improving the connection effect and ensuring a stable connection between the guide flare device and the end of the sliding contact line.

[0027] The present invention will be further illustrated by way of embodiments below, but the present invention is not limited to the scope of the embodiments described herein.

[0028] like Figure 1-6 As shown, a guide horn device for a current collector includes a device body 1; a horn 2 and a socket 3 are respectively provided on the left and right sides of the device body 1; it also includes:

[0029] The power supply wiring mechanism is provided in multiple ways and is installed on the outer wall of the horn mouth 2. The inner walls of the front and rear sides of the horn mouth 2 and the inner wall of the top side of the horn mouth 2 are provided with guide grooves 6. Conductor slots 7 are provided on the groove walls of the guide grooves 6. The end of the conductor slot 7 away from the plug 3 is provided with an outlet slot 8 connected to the power supply wiring mechanism.

[0030] Positioning mechanism 5 is disposed on the outside of the socket 3.

[0031] In practical implementation, there are five power supply wiring mechanisms. Two power supply wiring mechanisms are installed on the front outer wall and the back outer wall of the horn mouth 2, while the last power supply wiring mechanism is installed on the top outer wall of the horn mouth 2. In the power supply wiring mechanism located at the top of the horn mouth 2, the terminal block 1012 is divided into two parts and is located on the two side shells 101 respectively. After the two side shells 101 are spliced ​​together, the terminal block 1012 is also spliced ​​together.

[0032] like Figure 1-2 As shown, the main body 1 of the device is composed of two symmetrically arranged side shells 101 joined together; multiple connecting seats 1011 are fixedly installed on the top of each of the two side shells 101, and the connecting seats 1011 are provided with connecting holes. The connecting seats 1011 provide a fixed connection position between the two side shells 101. Figure 1-2 As shown, the two side shells 101 are aligned and fitted together, and the connecting seats 1011 on the two side shells 101 are also aligned. The bolts are passed through the connecting holes, and the nuts are tightened on the bolts to achieve a fixed installation.

[0033] like Figure 4-6 As shown, the power supply wiring mechanism includes a terminal block 1012; the terminal block 1012 is H-shaped and is provided with a mounting plate, the mounting plate having a second mounting hole 1014, and one side of the mounting plate being aligned with the slot 8.

[0034] When the entire flared device is connected to the conduit-type sliding contact line port, it is plugged into the sliding contact line port through the plug 3. During the plugging process, the copper conductor extending from the sliding contact line port is inserted into the conductor slot 7, and then the copper conductor is bent so that it passes through the slot 8. The end of the copper conductor is laid and attached to the mounting plate surface of the terminal block 1012. The end of the copper conductor has a hole, and the end of the external power supply wire also has a hole. The second mounting hole 1014 is threaded. By using an external screw, the screw passes through the hole at the end of the copper conductor and the hole at the end of the external wire, and then the screw is threaded into the second mounting hole 1014, so that the copper conductor and the external wire are pressed together onto the mounting plate to realize the connection and power supply.

[0035] It should be noted that the surface of the terminal block 1012 is provided with an insulating layer.

[0036] like Figure 1-2 As shown, the power supply wiring mechanism also includes a protective cover 4; the protective cover 4 has a wire outlet hole 402 and a through hole, and a mounting screw 401 is provided on the through hole; the terminal block 1012 has a first mounting hole 1013; the protective cover 4 covers and surrounds the terminal block 1012; and the mounting screw 401 is threadedly connected to the first mounting hole 1013.

[0037] The protective cover 4 is used to protect the terminal block 1012. The wire outlet hole 402 is used for external wires to pass through. The protective cover 4 is fixed to the terminal block 1012 by mounting screws 401 to surround the terminal block 1012 and achieve protection.

[0038] like Figure 4 As shown, the guide groove 6 gradually increases in width away from the socket 3. After the entire device is connected to the sliding contact line port, the guide groove 6 designed above is used to guide the current collector carbon brush into the copper conductor of the sliding contact line, reducing the collision between the current collector and the duct-type sliding contact line.

[0039] like Figure 3 As shown, the positioning mechanism 5 includes two symmetrically arranged driving members, which are respectively mounted on two side shells 101.

[0040] The driving component includes a first fixed frame 501 and a second fixed frame 502. Both the first fixed frame 501 and the second fixed frame 502 are fixedly installed on the top of the side shell 101. A rotating shaft 503 is rotatably installed between the first fixed frame 501 and the second fixed frame 502. A stud 504 is fixedly installed at the end of the rotating shaft 503. A nut seat 506 is threaded onto the stud 504. A connecting rod 507 is fixedly installed at the bottom of the nut seat 506. A positioning pin 508 is fixedly installed at the bottom end of the connecting rod 507. A guide hole is opened on the wall of the side shell 101. The positioning pin 508 is clearance-fitted with the guide hole. The studs 504 of the two driving components have opposite thread directions.

[0041] The end of the stud 504 away from the rotating shaft 503 is provided with an end seat, and the end seat is provided with a hexagonal insertion hole 505.

[0042] The two drive shafts 503 are respectively provided with a square post 509 and a square hole 510 at the ends away from the stud 504.

[0043] When the two side shells 101 are spliced, the driving components on the two side shells 101 are connected by square post 509 and square hole 510, so that the rotating shaft 503 and stud 504 in the two driving components can rotate together. An external hex wrench is inserted into the socket 505 and turned by the hex wrench, so that the stud 504 and rotating shaft 503 rotate together. Since the threads of the two driving component studs 504 are opposite, the two nut seats 506 move in opposite directions, moving closer or further away from each other. By moving the two nut seats 506 away from each other, the connecting rod 507 drives the positioning post 508 to be stored in the positioning hole. The positioning post 508 does not extend into the side shell 101.

[0044] The outer shell of the sliding contact line port is provided with a positioning hole adapted to the positioning post 508. After the entire device is plugged into the sliding contact line port through the plug 3, the positioning hole at the end of the sliding contact line is aligned with the positioning post 508. By bringing the two nut seats 506 closer to each other, the positioning post 508 is moved by the connecting rod 507, so that the positioning post 508 is inserted into the positioning hole. The positioning post 508 presses against the end face of the positioning hole, thus completing the positioning and limiting of the entire device at the sliding contact line port, so that the entire flared device is firmly connected to the sliding contact line.
