Abstract
Description
Technical Field
[0001] This utility model relates to the field of overhead crane technology, and in particular to a sliding contact line for a multifunctional overhead crane. Background Technology
[0002] The sliding contact line current collector sliding plates used in the multi-functional overhead crane have potential safety hazards, specifically: poor contact, overheating, and deformation at the connection between the current collector sliding plates and the wiring copper plate, and a phase loss in the main power supply of the multi-functional overhead crane. Maintenance personnel analyzed and discussed these issues and identified two main causes:
[0003] First: Because of its special material, if the slider is subjected to too much force when installing the wiring copper plate, it may crack directly, resulting in insufficient fit at the connection point.
[0004] Second: The force-bearing area of the sliding plate is too small. When subjected to external force during operation, it will crack or break directly at the screw hole. Moreover, the outer protective cover cannot detect the problem in time. Continued use will cause it to heat up and spark. If it is not detected in time, it will ignite the protective cover, causing a fire and a power outage in the work area, which will affect the normal production of electrolysis.
[0005] Therefore, this utility model proposes a multifunctional overhead crane sliding contact line to solve the problems existing in the prior art. Utility Model Content
[0006] To address the aforementioned issues, this utility model proposes a sliding contact line for a multi-functional overhead crane. This sliding contact line effectively avoids poor contact, overheating, and deformation at the connection between the current collector sliding plate and the wiring copper plate of the multi-functional overhead crane, as well as the loss of a phase in the main power supply of the multi-functional overhead crane, thus fundamentally solving potential safety hazards.
[0007] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a multi-functional overhead crane sliding contact line, including a current collector sliding plate and a wiring copper plate, wherein a first reinforcing plate is provided below the top end of the current collector sliding plate and a second reinforcing plate is provided below the bottom end of the current collector sliding plate, and the wiring copper plate is installed on the first reinforcing plate or the second reinforcing plate.
[0008] Fixing holes are provided at corresponding positions of the first reinforcing plate, the current collector slider, the second reinforcing plate, and the wiring copper plate. The fixing holes are used to insert screw fastening components, which are used to fix the first reinforcing plate, the current collector slider, the second reinforcing plate, and the wiring copper plate.
[0009] A further improvement is that both the first reinforcing plate and the second reinforcing plate are copper plates, and both the surfaces of the first reinforcing plate and the second reinforcing plate are smooth.
[0010] A further improvement is that the fastening assembly has at least two sets, the fastening assembly includes a bolt and a nut, the bolt passes through a fixing hole, and the lower end of the bolt is fixed by the nut.
[0011] A further improvement is that a first washer is provided between the bolt head and the first reinforcing plate, and a second washer is provided between the nut and the second reinforcing plate.
[0012] A further improvement is that the first gasket and the second gasket have the same structure, and both the first gasket and the second gasket are elastic sheets, with spring grooves on the outer side of both the first gasket and the second gasket.
[0013] A further improvement is that: both the first and second washers have protrusions around the center, and multiple sets of protrusions are arranged at equal angles; the bolt head presses against the protrusions of the first washer, and the nut presses against the protrusions of the second washer.
[0014] A further improvement is that the copper plate for wiring has wiring holes for connecting cables.
[0015] The beneficial effects of this utility model are as follows:
[0016] 1. This utility model, without affecting the original installation method, installs a first reinforcing plate and a second reinforcing plate on both sides of the current collector slide. The screw fastening assembly passes through the fixing hole to fix the first reinforcing plate, the current collector slide, the second reinforcing plate and the wiring copper plate, effectively increasing the force-bearing area at the fixing point of the current collector slide and the wiring copper plate, forming a protection to prevent breakage at the fixing hole, effectively avoiding poor contact, overheating and deformation at the connection point of the current collector slide and the wiring copper plate and the loss of a phase in the main power supply of the multi-functional overhead crane, fundamentally solving potential safety hazards, reducing daily equipment failures and the labor intensity of maintenance personnel, and ensuring normal production in the electrolysis workshop.
[0017] 2. In the process of fixing the current collector sliding plate and the wiring copper plate, this utility model adds a first washer between the bolt head and the first reinforcing plate, and adds a second washer between the nut and the second reinforcing plate. Through the elastic plate with its side groove structure, after installation and tightening, it provides a clamping force that tends to elastically return to its original position, thereby improving the tightness of the bolt assembly. In conjunction with the convex contact bolt head and nut, it increases the friction force, reduces the loosening of the bolt and nut, and ensures the stability of the installation.

[0022] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.
[0023] Example 1
[0024] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a multifunctional overhead crane sliding contact line, including a current collector sliding plate 1 and a wiring copper plate 2. A first reinforcing plate 3 is provided below the top end of the current collector sliding plate 1, and a second reinforcing plate 4 is provided below the bottom end of the current collector sliding plate 1. The wiring copper plate 2 is installed on the first reinforcing plate 3 or the second reinforcing plate 4.
[0025] Fixing holes 5 are provided at corresponding positions of the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. These fixing holes 5 are used to insert screw fastening components, which are used to fix the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. Without affecting the original installation method, the first reinforcing plate 3 and the second reinforcing plate 4 are installed on both sides of the current collector slider 1. The screw fastening components pass through the fixing holes 5 to fix the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. This effectively increases the stress area at the fixing point between the current collector slider 1 and the wiring copper plate 2, forming a protective barrier to prevent breakage at the fixing holes 5. It also effectively avoids poor contact, overheating, and deformation at the connection between the current collector slider 1 and the wiring copper plate 2, as well as the loss of a phase in the main power supply of the multi-functional overhead crane. This fundamentally solves potential safety hazards, reduces daily equipment failures and the labor intensity of maintenance personnel, and ensures normal production in the electrolysis workshop.
[0026] Both the first reinforcing plate 3 and the second reinforcing plate 4 are copper plates to ensure conductivity. Furthermore, both the surfaces of the first reinforcing plate 3 and the second reinforcing plate 4 are smooth to ensure sufficient contact area with the current collector slider 1 and the wiring copper plate 2, thus maintaining excellent conductivity.
[0027] The fastening assembly has two sets, each including a bolt 6 and a nut 7. The bolt 6 passes through the fixing hole 5, and its lower end is fixed by the nut 7. A first washer 8 is provided between the bolt head of the bolt 6 and the first reinforcing plate 3, and a second washer 9 is provided between the nut 7 and the second reinforcing plate 4. The first washer 8 and the second washer 9 have the same structure and are both elastic sheets. Both the first washer 8 and the second washer 9 have spring grooves 10 on their outer sides. Both the first washer 8 and the second washer 9 have protrusions 11 around their centers, and multiple sets of protrusions 11 are arranged at equal angles. The bolt head of the bolt 6 presses against the protrusions 11 of the first washer 8, and the nut 7 presses against the protrusions 11 of the second washer 9. During use, during the fixing of the current collector slider 1 and the wiring copper plate 2, a first washer 8 is added between the screw head of the bolt 6 and the first reinforcing plate 3, and a second washer 9 is added between the nut 7 and the second reinforcing plate 4. Through the elastic plate body and the structure of the side groove 10, after installation and tightening, it plays a role in providing a resistance force that tends to elastically return to its original position, thereby improving the tightness of the bolt assembly. In conjunction with the protrusion 11, it contacts the screw head of the bolt 6 and the nut 7 to increase friction, reduce the loosening of the bolt 6 and the nut 7, and ensure the stability of the installation.
[0028] Example 2
[0029] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a multifunctional overhead crane sliding contact line, including a current collector sliding plate 1 and a wiring copper plate 2. A first reinforcing plate 3 is provided below the top end of the current collector sliding plate 1, and a second reinforcing plate 4 is provided below the bottom end of the current collector sliding plate 1. The wiring copper plate 2 is installed on the first reinforcing plate 3 or the second reinforcing plate 4.
[0030] Fixing holes 5 are provided at corresponding positions of the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. These fixing holes 5 are used to insert screw fastening components, which are used to fix the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. Without affecting the original installation method, the first reinforcing plate 3 and the second reinforcing plate 4 are installed on both sides of the current collector slider 1. The screw fastening components pass through the fixing holes 5 to fix the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4, and the wiring copper plate 2. This effectively increases the stress area at the fixing point between the current collector slider 1 and the wiring copper plate 2, forming a protective barrier to prevent breakage at the fixing holes 5. It also effectively avoids poor contact, overheating, and deformation at the connection between the current collector slider 1 and the wiring copper plate 2, as well as the loss of a phase in the main power supply of the multi-functional overhead crane. This fundamentally solves potential safety hazards, reduces daily equipment failures and the labor intensity of maintenance personnel, and ensures normal production in the electrolysis workshop.
[0031] Both the first reinforcing plate 3 and the second reinforcing plate 4 are copper plates to ensure conductivity. Furthermore, both the surfaces of the first reinforcing plate 3 and the second reinforcing plate 4 are smooth to ensure sufficient contact area with the current collector slider 1 and the wiring copper plate 2, thus maintaining excellent conductivity.
[0032] The copper wiring plate 2 is provided with wiring holes 12, which are used to connect cables. In use, the screw assembly is passed through the fixing hole 5 to fix the first reinforcing plate 3, the current collector slider 1, the second reinforcing plate 4 and the copper wiring plate 2, and the wiring holes 12 on the copper wiring plate 2 are connected to the cable for power transmission.
[0033] This multi-functional overhead crane sliding contact line, without affecting the original installation method, has a first reinforcing plate 3 and a second reinforcing plate 4 installed on both sides of the current collector sliding plate 1. The screw fastening assembly passes through the fixing hole 5 to fix the first reinforcing plate 3, the current collector sliding plate 1, the second reinforcing plate 4 and the wiring copper plate 2. This effectively increases the force-bearing area at the fixing point of the current collector sliding plate 1 and the wiring copper plate 2, forming a protection to prevent breakage at the fixing hole 5. It effectively avoids poor contact, overheating and deformation at the connection point of the current collector sliding plate 1 and the wiring copper plate 2, as well as the loss of a phase in the main power supply of the multi-functional overhead crane. It fundamentally solves potential safety hazards, reduces daily equipment failures and the labor intensity of maintenance personnel, and ensures normal production in the electrolysis workshop. Meanwhile, during the fixing of the current collector slider 1 and the wiring copper plate 2, a first washer 8 is added between the screw head of the bolt 6 and the first reinforcing plate 3, and a second washer 9 is added between the nut 7 and the second reinforcing plate 4. Through the elastic plate body and the structure of the side groove 10, after installation and tightening, it plays a role in the resistance force that tends to elastically return, thereby improving the tightness of the bolt assembly. In conjunction with the protrusion 11 contacting the screw head of the bolt 6 and the nut 7, it increases the friction force, reduces the loosening of the bolt 6 and the nut 7, and ensures the stability of the installation.
