Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets and relates to a special copper guide rail. Background Art

[0002] The circuit breaker trolley is an important device in the switch cabinet. The trolley can be shaken in and out relative to the switch cabinet and has multiple working states. Since the trolley is a large current carrying device, it is very necessary to ground the trolley inside the switch cabinet.

[0003] In the prior art, the grounding method for switch cabinet trolleys is usually to equip the frame slide rails on both sides of the cabinet with a grounding function for pushing the trolley. In order to ensure the conduction effect, a whole copper guide rail is usually used to achieve both support and grounding. First, the material cost is high, and the whole setting causes a certain amount of waste. Second, the copper guide rail has poor supporting strength under the heavy pressure and repeated movements of the heavy trolley and is easily deformed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a special copper guide rail.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A special copper guide rail includes a linear track frame for being set on the inner wall of a switch cabinet. The linear track frame includes a linear rail for supporting the pulley of a trolley, a grounded copper bracket for contacting the wiring clamp of the trolley, and an anti-warping bracket. A space for accommodating the pulley of the trolley is formed between the anti-warping bracket and the linear rail.

[0007] Furthermore, the linear rail and the grounding copper bracket are both arranged in a straight line along the moving direction of the trolley.

[0008] Furthermore, the anti-warping bracket is arranged parallel to the linear rail, a set distance is formed between the anti-warping bracket and the linear rail, and the bottom of the anti-warping bracket forms an abutting surface for abutting against the top of the pulley.

[0009] Furthermore, the linear track frame and the anti-warping bracket are both made of aluminum-zinc coated plate or cold-rolled plate.

[0010] Furthermore, the anti-warping bracket is formed by bending along the top of the linear track frame.

[0011] In summary, the benefits of the present invention are:

[0012] The utility model adopts a combination of a grounding copper bracket and an anti-warping bracket, so that the grounding copper bracket is only set in the stroke when the trolley is powered on to ensure grounding, and the anti-warping bracket is used to carry the trolley. Each performs its function, which not only ensures the effect of sufficient grounding, but also ensures the supporting strength of the entire guide rail, while also saving material costs.

[0016] The following describes the embodiments of the present invention through specific examples. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features within these embodiments may be combined with one another, unless they conflict.

[0017] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed arbitrarily, and the component layout type may also be more complicated.

[0018] All directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, horizontal, vertical...) are only used to explain the relative position relationship, movement status, etc. between the various components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0019] Due to installation errors and other reasons, the parallel relationship referred to in the embodiments of the present invention may actually be an approximately parallel relationship, and the perpendicular relationship may actually be an approximately perpendicular relationship.

[0020] A special copper guide rail is installed in the circuit breaker chamber of the switch cabinet and is used for guiding, supporting and grounding the trolley when it is rocked in and out of the circuit breaker chamber.

[0021] Specifically, refer to Figure 1 and Figure 2 The copper guide rail includes a linear track frame 1, which is arranged on the left and right side walls of the circuit breaker chamber and is fixedly connected by bolts, rivets, etc. A linear rail 11 for supporting the pulley on the trolley is formed on the linear track frame 1. The linear rail 11 is arranged in a straight line along the direction of the trolley's rocking in and out. A bottom support plate is provided at the bottom of the trolley, and the pulleys are provided on the left and right sides of the bottom support plate, so that the pulleys on both sides are respectively placed on the top surface of the linear rail 11. The rolling cooperation between the pulley and the linear rail 11 realizes the support and movement guidance of the trolley in the circuit breaker chamber.

[0022] The copper guide rail also includes a grounding copper bracket 12, which is fixedly arranged on the linear track frame 1 and is used to contact the grounding clamp on the trolley to form grounding conduction. The grounding copper bracket 12 is arranged in a straight line along the swinging direction of the trolley, and the grounding copper bracket 12 is set to a set length along the straight line direction. The trolley is within the swinging stroke in and out of the circuit breaker chamber. More specifically, within the stroke between the working position and the test position of the trolley, the grounding clamp of the trolley maintains contact with the grounding copper bracket 12.

[0023] When the trolley is swung into the circuit breaker chamber until it reaches the working position, the interface on the trolley is connected with the interface in the circuit breaker chamber. During the connection process, the trolley will be subjected to a certain abutting force, causing the trolley to tilt relative to the bottom support plate. Therefore, further, the copper guide rail also includes an anti-tilt bracket 13, which is arranged in a straight line along the swing-in and swing-out direction of the trolley, so that the anti-tilt bracket 13 is parallel to the linear track frame 1, and a set height spacing is formed between the anti-tilt bracket 13 and the linear track frame 1 for accommodating the pulley, the top of the pulley contacts the bottom of the anti-tilt bracket 13, or a slight gap is left between the top of the pulley and the bottom of the anti-tilt bracket 13. When the trolley is subjected to the abutting force during the connection process and tends to tilt, the pulley presses upward against the anti-tilt bracket 13 to prevent the trolley from further tilting, while not affecting the inward swinging of the trolley; the anti-tilt bracket 13 can be formed by a ninety-degree bend at the top of the linear track frame 1, forming an integrated structure with the linear track frame 1.

[0024] The anti-warping bracket 13 and the grounding copper bracket 12 are connected and arranged in the same length direction.

[0025] In this embodiment, the linear track frame 1 and the anti-warping bracket 13 are preferably made of aluminum-zinc coated plate or cold-rolled plate to save material cost and ensure structural strength, and the grounding copper bracket 12 is made of copper plate to ensure grounding performance.

[0026] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
