Description

Technical Field

[0001] The utility model relates to the field of circuit connection, in particular to a stable connected busbar. Background Art

[0002] Busbars are components used to supply power to mobile equipment. The current collector slides on the busbar's guide rails, transferring the power from the busbar to the device. They are commonly used to power mobile equipment such as cranes and electric hoists. Because these devices experience inherent vibration during operation, the current collector is designed with a tension spring, shaft, and sleeve to ensure full contact between the current collector and the busbar conductor, effectively transferring the power from the busbar to the device.

[0003] The collector in the prior art generally consists of two parallel arms, with a spring connected between the two arms, one end of the two arms hinged together by a mounting shaft, and the mounting shaft is rotatably mounted on the fixed base through a shaft sleeve, so that the arm can swing left and right to a large extent in the horizontal plane. In order to facilitate the stable installation of the mounting shaft on the fixed base, the length of the mounting shaft is generally relatively long, which makes the spacing between the two arms larger, resulting in a smaller swing amplitude of the arm. Once the spacing between the fixed base and the sliding guide rail is significantly enlarged or rapidly reduced, it is easy for the slide box to fall off the sliding line, and the contact shoe installed at one end of the arm basically does not rotate, so once the arm fails to slide along the sliding conductor, the contact shoe can easily fall off the sliding guide rail, causing the circuit to be broken. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the collector in the prior art generally consists of a mechanism consisting of two parallel arms, which makes the contact between the contact shoe and the sliding line guide rail unstable and unreliable. The present invention provides a stable connected sliding line to solve the above problem.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a stably connected sliding bus bar, including a sliding bus bar guide rail and a current collector, the current collector including a mounting seat and a bracket, the bracket is rotatably mounted on the mounting seat through a hinge point, the bracket has a pressure arm, the end of the pressure arm is fixedly connected to a brush seat, and a contact shoe is installed on the brush seat; a compression spring is installed between the mounting seat and the pressure arm, and a tension spring is installed between the mounting seat and the brush seat, and the compression spring and the tension spring drive the bracket to rotate toward the sliding bus bar with the hinge point as the center.

[0006] Furthermore: the sliding wire guide rail includes a guide rail bracket and a slide rail installed in the guide rail bracket, the cross-sectional shape of the slide rail is a V-shape with a circular arc bottom, the bottom cross-sectional shape of the contact shoe is a V-shape with a circular arc bottom that matches the cross-sectional shape of the slide rail, and the contact shoe is tightly fitted to the slide rail.

[0007] Furthermore: a pressure plate is provided on the mounting seat, and the pressure plate is fixedly mounted on the mounting seat by mounting bolts, and the pressure plate is connected to the external walking frame; a buckle plate is provided on the bracket, and the buckle plate is buckled on the walking frame as the bracket rotates along the hinge point.

[0008] Furthermore: the number of the brackets is two or more, and several of the brackets are insulated from each other and arranged in parallel.

[0009] The beneficial effect of the present invention is that a stably connected busbar of the present invention adopts a rotating hinged bracket to drive the contact shoe to be pressed against the busbar guide rail, and adopts a compression spring and a tension spring to drive the bracket to rotate, providing sufficient and reliable contact pressure, ensuring reliable fitting contact between the contact shoe and the busbar guide rail, and achieving the effect of stable connection of the busbar.

[0018] In addition, the terms "first", "second", etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances. In addition, in the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0019] Any process or method description in a flowchart or otherwise described herein may be understood to represent a module, segment or portion of code comprising one or more executable instructions for implementing the steps of a specific logical function or process, and the scope of the preferred embodiments of the present invention includes alternative implementations in which functions may be performed out of the order shown or discussed, including performing functions in a substantially simultaneous manner or in the reverse order depending on the functions involved, which should be understood by those skilled in the art to which the embodiments of the present invention pertain.

[0020] like Figures 1 to 4 As shown, the utility model provides a stably connected busbar, including a busbar guide rail 1 and a current collector 2, the current collector 2 including a mounting seat 3 and a bracket 4, the bracket 4 is rotatably mounted on the mounting seat 3 through a hinge point 5, the bracket 4 has a pressure arm 6, the end of the pressure arm 6 is fixedly connected to a brush seat 7, and a contact shoe 8 is installed on the brush seat 7; a compression spring 9 is installed between the mounting seat 3 and the pressure arm 6, and a tension spring 10 is installed between the mounting seat 3 and the brush seat 7, the compression spring 9 and the tension spring 10 drive the bracket 4 to rotate toward the busbar guide rail 1 with the hinge point 5 as the center.

[0021] When the busbar is working, the current collector 2 needs to be reliably and stably installed tightly on the busbar guide rail 1. Compared with the existing busbar, the compression spring 9 is directly installed on the contact shoe 8, and the contact shoe 8 is directly pushed to press the busbar guide rail 1. The structure of the busbar disclosed in this patent adopts a hinged bracket 4, and a compression driving force is set on the pressure arm 6. Specifically, the bracket 4 is installed as a whole on the mounting seat 3 and can rotate along the hinge point 5 as the center. The compression spring 9 and the tension spring 10 are respectively installed at different positions of the mounting seat 3 and the pressure arm 6 or the brush seat 7. The compression spring 9 provides a pushing force and the tension spring 10 provides a pulling force. Both forces drive the rotation of the bracket 4, so that the bracket 4 rotates along the hinge point 5 and realizes the rotation of the bracket 4 toward the busbar guide rail 1, and finally achieves the effect of pressing the contact shoe 8 against the busbar guide rail 1.

[0022] Compared with the method of directly pushing the contact shoe 8 in the prior art, the technical solution of this patent uses two springs providing external force, namely the compression spring 9 and the tension spring 10, to act simultaneously, thereby increasing the positive pressure of the contact shoe 8 pressed against the sliding guide rail 1. At the same time, the rotation of the pressure arm 6 or the bracket 4 has a certain torque, which greatly improves the fitting effect of the contact shoe 8 pressed against the sliding guide rail 1, and makes the force applied to the contact shoe 8 by the spring external force more uniform and stable, ensuring the stable and reliable connection of the sliding line.

[0023] The sliding guide rail 1 includes a guide rail bracket 11 and a slide rail 12 installed in the guide rail bracket 11. The cross-sectional shape of the slide rail 12 is a V-shaped bottom with a circular arc. The bottom cross-sectional shape of the contact shoe 8 is a V-shaped bottom with a circular arc that matches the cross-sectional shape of the slide rail 12. The contact shoe 8 is tightly fitted against the slide rail 12.

[0024] Although the slide rail 12 and the contact shoe 8 slide against each other, they maintain contact with each other. This contact is the prerequisite for the normal operation of the electrical connection of the busbar line. In this patent, the cross-sectional shape of the contact part between the slide rail 12 and the contact shoe 8 is a V-shape with a circular arc at the bottom. This cross-sectional shape increases the contact area between the slide rail 12 and the contact shoe 8, while avoiding the disadvantage of low structural strength caused by sharp parts, and greatly increases the wear resistance of the contact friction between them. At the same time, the V-shaped structure of the circular arc at the bottom allows the two to have an adjustment margin in the direction of rotation during the contact process. When the position or shape of the slide rail 12 or the contact shoe 8 is offset or slightly deformed, it can be adaptively adjusted while maintaining constant contact.

[0025] A pressure plate 13 is provided on the mounting seat 3, and the pressure plate 13 is fixedly installed on the mounting seat 3 by mounting bolts. The pressure plate 13 is connected to the external walking frame; a buckle plate 14 is provided on the bracket 4, and the buckle plate 14 is buckled on the walking frame as the bracket 4 rotates along the hinge point 5.

[0026] The external traveling frame is a common structure required for busbar installation, as it provides a continuous electrical connection to the moving mechanism. During installation, the busbar guide rail 1 is installed parallel to the travel direction of the external traveling frame. The current collector 2 is then mounted on the external traveling frame. Driven by the traveling frame, the current collector 2 slides against the guide rail 1 while maintaining an electrical connection.

[0027] The current collector 2 can be securely mounted on the traveling frame by means of the pressure plate 13, and the pinch plate 14 on the bracket 4 serves to limit the rotation direction of the bracket 4. When the current collector 2 is operating normally, i.e., when the slide rail 12 and the contact shoe 8 are in normal contact, the pinch plate 14 does not press the traveling frame. However, when the contact shoe 8 is not in normal contact with the slide rail 12, the bracket 4 is kept in a rotating state under the action of the tension spring 10 and the compression spring 9. To prevent the bracket 4 from rotating excessively along the hinge point 5, the pinch plate 14 is blocked by the traveling frame, i.e., the pinch plate 14 is pressed against the traveling frame, preventing further rotation of the bracket 4, thereby maintaining the normal operating state of the contact shoe 8 and facilitating subsequent contact with the slide rail 12.

[0028] There are two or more brackets 4, and several brackets 4 are insulated from each other and arranged in parallel. Because the busbar usually needs to connect multiple lines when in use, multiple brackets 4 correspond to multiple contact shoes 8 and multiple slide rails 12, thus generating multiple electrical connections. The lines are insulated from each other to prevent short circuits, ensuring reliable transmission of multiple lines.

The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
