Description

Technical Field

[0001] The present application relates to the technical field of power transmission equipment, and in particular to a tubular busbar connection structure. Background Art

[0002] The busbar, also known as the conductor, is a power transmission device that supplies power to mobile equipment. It mainly consists of two parts: the busbar rail and the current collector. The busbar rail is a fixed part that is electrically connected to the power source; the current collector is a sliding part that can slide on the busbar rail and contact the copper bar to draw power. The current collector is used to connect to the mobile motor. Busbars are widely used in industrial applications, such as cranes, automated production lines, logistics systems and other mobile equipment, providing these devices with a stable and safe power supply.

[0003] In the prior art, the length of the guide rail of the tubular busbar is adaptively adjusted according to the application occasion, and usually two sections of the tubular busbar are installed and connected by bolts. Although the installation method of connecting by bolts is simple and easy, it is difficult to ensure the straightness of the guide rail after connection by only connecting by bolts, and the guide rail after connection is easy to loosen due to vibration or external force during long-term use, which is easy to cause poor contact or even power failure.

[0004] A Chinese patent with announcement number CN210866725U discloses a tubular busbar connection structure, including a connection device connecting two sections of tubular busbars, the tubular busbar including a guide rail and a copper bar inserted in the guide rail, the connection device including a fixed plate arranged on both sides of the copper bar, two positioning plates respectively fixed to the two end surfaces in the height direction of the fixed plate, two clamping plates respectively arranged on the opposite sides of the two positioning plates and a threaded column threadedly connected to one side of the fixed plate; the positioning plate is horizontally extended to the side close to the copper bar; the two clamping plates are respectively arranged perpendicular to the two positioning plates; an abutment plate is slidably provided between the two positioning plates, and the abutment plate and the fixed plate are arranged parallel to each other; one end of the threaded column passes through the fixed plate and abuts against the abutment plate.

[0005] When the above connection structure is used to install and connect two sections of tubular busbars, the copper sheet extending out of the tubular busbar is clamped and fixed by the fixing plate and the abutting plate to improve the straightness between the copper wires when the two sections of tubular busbars are connected. However, the copper sheet is ductile. When the copper sheet is inserted into the connection device, if the connection device is offset, the copper sheet will also deform accordingly with the connection device, making it difficult to ensure the overall straightness of the two sections of tubular busbars. Utility Model Content

[0006] In order to improve the overall straightness of the tubular busbar after connection, the present application provides a tubular busbar connection structure.

[0007] The present application provides a tubular busbar connection structure that adopts the following technical solution:

[0008] A tubular busbar connection structure comprises a guide rail, a copper bar inserted in the guide rail and a connection mechanism for connecting two sections of busbars, the connection mechanism comprising a limiting sleeve arranged corresponding to the copper bar and a pressure plate slidably arranged in the limiting sleeve for jointly pressing the two copper bars, a positioning buckle is fixedly arranged on the opposite ends of the two guide rails corresponding to each limiting sleeve, interfaces are provided at both ends of the limiting sleeve corresponding to the positioning buckle, and the positioning buckle and the interface are plugged in and matched.

[0009] By adopting the above technical solution, the pressure plate in the limit sleeve can stably press the copper bar after it is inserted, ensuring good contact of the copper bar at the connection. On this basis, the limit sleeve and the positioning buckle fixed on the guide rail are plugged in and matched to further ensure the precise alignment of the two guide rails at the connection, thereby improving the overall straightness of the two adjacent guide rails after connection. This method not only improves the stability of the connection, but also greatly extends the service life of the busbar.

[0010] Optionally, push rods are slidably inserted into the back sides of the two limit sleeves distributed in the horizontal direction, and the ends of the push rods extending into the limit sleeves abut against the pressure plate. A compression spring is sleeved on the push rods, and the compression spring is located inside the limit sleeve and abuts against the pressure plate and the inner side walls of the limit sleeve. The end of the push rod extending out of the limit sleeve is provided with an end head, and when the compression spring is in a natural state, the end head is abutted against the outer side wall of the limit sleeve.

[0011] By adopting the above technical solution, when the copper bar needs to be connected, the operator grabs the end and overcomes the elastic force of the compression spring to pull the push rod away from the pressure plate. The push rod drives the pressure plate to move synchronously, and then the copper sheet is inserted into the limiting sleeve. The end is released, and under the elastic recovery action of the compression spring, the pressure plate always presses the copper bar tightly against the inner wall of the limiting sleeve, ensuring the stable contact of the copper bar at the connection, thereby improving the stability and reliability of the use of the busbar.

[0012] Optionally, there are two push rods distributed along the length direction of the limiting sleeve, and the parts of the two push rods located outside the limiting sleeve are jointly sleeved with a connecting rod, and the connecting rod is located between the end head and the outer side wall of the limiting sleeve.

[0013] By adopting the above technical solution, the two push rods can be arranged to tighten the abutment plate more stably and reliably, and the two push rods are arranged at the two ends of the fixed plate, so that the abutment plate exerts a uniform force on the two copper bars, thereby improving the flatness of the copper bar connection. The arrangement of the connecting rod facilitates the synchronous pulling of the two push rods, thereby improving the work efficiency of the docking and fixing of the copper bars.

[0014] Optionally, a pull ring is provided on the side wall of the connecting rod away from the limiting sleeve.

[0015] By adopting the above technical solution, the setting of the pull ring provides convenience for the operator to pull the connecting rod.

[0016] Optionally, a telescopic rod is arranged between each two adjacent limiting sleeves, and the telescopic rod is arranged in a length direction perpendicular to the limiting sleeves, and the bottom of the telescopic rod is arranged on the side wall of one of the limiting sleeves, and the rod end of the telescopic rod is arranged on the opposite side wall of the adjacent limiting sleeves.

[0017] By adopting the above technical solution, the addition of the telescopic rod can further improve the stability of the limit sleeves when connected to the guide rail. When the guide rail is subjected to external force, the telescopic rod can absorb part of the stress, thereby reducing the impact on the connection. At the same time, the telescopic rod can also match the spacing of the limit sleeves when connecting guide rails of different specifications to a certain extent, so as to meet the needs of different installation environments.

[0018] Optionally, the bottom and the rod end of the telescopic rod are both provided with connecting holes perpendicular to the length direction of the telescopic rod, and elastic hooks are provided corresponding to the connecting holes on the opposite side walls of two adjacent limiting sleeves. The elastic hooks pass through the connecting holes and limit the bottom or the rod end of the telescopic rod between the elastic hook and the side wall of the limiting sleeve.

[0019] By adopting the above technical solution, the telescopic rod is detachably arranged between the elastic hook and the connecting through hole, so that when the limiting sleeve is damaged and needs to be replaced, only the damaged limiting sleeve needs to be replaced, avoiding the need to replace the entire connecting mechanism, thereby reducing the maintenance cost of the connecting device.

[0020] Optionally, an observation hole is opened along the length of the side wall of the limiting sleeve away from the push rod, and the observation hole connects the inside and outside of the limiting sleeve and is used to observe the position of the copper bar end extending inside the limiting sleeve.

[0021] By adopting the above technical solution, the operator can visually observe the position of the copper bar in the limit sleeve through the observation hole. This not only facilitates timely adjustment of the position of the copper bar, but also provides great convenience during maintenance and overhaul. At the same time, the design of the observation hole can also reduce the weight of the limit sleeve and achieve lightweight structure.

[0022] Optionally, a non-slip pad is provided on one side of the pressure plate close to the copper bar.

[0023] By adopting the above technical solution, the provision of the anti-slip pad can increase the friction between the pressing plate and the copper bar, preventing the copper bar from sliding when being pressed, thereby further ensuring the stability of the connection.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The pressure plate in the limit sleeve can stably press the copper bar after it is inserted, ensuring good contact of the copper bar at the connection. On this basis, the limit sleeve and the positioning buckle fixed on the guide rail are plugged in to further ensure the precise alignment of the two guide rails at the connection, thereby improving the overall straightness of the two adjacent guide rails after connection. This method not only improves the stability of the connection, but also greatly extends the service life of the busbar;

[0026] 2. When the copper bar needs to be connected, the operator grabs the end and overcomes the elastic force of the compression spring to pull the push rod away from the pressure plate. The push rod drives the pressure plate to move synchronously, and then inserts the copper sheet into the limiting sleeve. The end is released. Under the elastic recovery of the compression spring, the pressure plate always presses the copper bar tightly against the inner wall of the limiting sleeve, ensuring the stable contact of the copper bar at the connection, thereby improving the stability and reliability of the busbar.

[0027] 3. The setting of two push rods can make the abutment plate more stable and reliable, and the two push rods are set at the two ends of the fixed plate, so that the abutment plate exerts a uniform force on the two copper bars, thereby improving the flatness of the copper bar connection. The setting of the connecting rod facilitates the synchronous pulling of the two push rods, thereby improving the work efficiency of the docking and fixing of the copper bars.

[0034] The following is combined with Figure 1-4 This application is described in further detail.

[0035] The embodiment of the present application discloses a tubular busbar connection structure.

[0036] Reference Figure 1 A tubular busbar connection structure includes a guide rail 1, a copper bar 2 and a connection mechanism 3. The connection mechanism 3 is inserted into a slot in the guide rail 1 and is used to connect the guide rail 1 and the copper bar 2 of two sections of busbars.

[0037] Reference Figures 1 to 3 The connecting mechanism 3 includes a limiting sleeve 31 and a pressure plate 32. One limiting sleeve 31 is provided for each copper bar 2. Four are taken as an example in this embodiment. A positioning buckle 11 is fixedly provided on the opposite side walls of the two guide rails 1 corresponding to each limiting sleeve 31. Interfaces 311 are provided on the top walls at both ends of the limiting sleeve 31 corresponding to the buckles that connect the inside and the outside. The positioning buckle 11 is inserted into the limiting sleeve 31 and clamped at the interface 311, and is plugged into and matched with the interface 311.

[0038] Reference Figure 1 In order to facilitate observation of the position of the copper strip 2 in the limiting sleeve 31, an observation through hole 312 is provided on the side wall of the limiting sleeve 31 away from the push rod 4 along its length direction. The observation through hole 312 connects the inside and outside of the limiting sleeve 31, so that the operator can intuitively observe the extension position of the end of the copper strip 2 in the limiting sleeve 31.

[0039] Reference Figure 1 and Figure 2 The pressure plate 32 is slidably arranged inside the limiting sleeve 31 along a length direction perpendicular to the limiting sleeve 31. The pressure plate 32 is used to jointly press the two copper bars 2 inserted in the same limiting sleeve 31, and a non-slip pad 321 is fixedly arranged on the side of the pressure plate 32 facing the pressed copper bars 2.

[0040] Reference Figure 2 , push rods 4 are slidably penetrated on the opposite sides of the two limit sleeves 31 distributed in the horizontal direction, and the end of the push rod 4 extending into the limit sleeve 31 is fixedly arranged on the pressure plate 32. At the same time, a compression spring 5 is sleeved on the push rod 4, and the compression spring 5 is located inside the limit sleeve 31, and its two ends are respectively abutted on the pressure plate 32 and the inner side wall of the limit sleeve 31, and a terminal 41 is fixedly arranged on the end of the push rod 4 extending out of the limit sleeve 31.

[0041] Reference Figure 1 and Figure 2There are two push rods 4 distributed along the length direction of the limiting sleeve 31, and the two push rods 4 are located outside the limiting sleeve 31 and are sleeved with a connecting rod 6. The connecting rod 6 is located between the end 41 and the outer wall of the limiting sleeve 31, and a pull ring 61 is fixedly provided on the side wall of each connecting rod 6 away from the limiting sleeve 31.

[0042] Reference Figure 1 and Figure 2 When the compression spring 5 is in a natural state, the connecting rod 6 abuts between the end 41 and the outer side wall of the limiting sleeve 31 .

[0043] Reference Figures 2 to 4 In order to improve the stability of the entire connection structure, a telescopic rod 7 is arranged between the two limiting sleeves 31 distributed vertically. The telescopic rod 7 is square and is arranged near the middle of the limiting sleeve 31 along the length direction perpendicular to the limiting sleeve 31. The bottom and the rod end of the telescopic rod 7 are both opened with connecting through holes 71 perpendicular to their own length direction. Elastic hooks 313 are fixedly arranged on the opposite side walls of the two limiting sleeves 31 distributed vertically corresponding to the connecting through holes 71. The elastic hooks 313 can penetrate the connecting through holes 71 and limit the bottom or the rod end of the telescopic rod 7 between the elastic hooks 313 and the side walls of the limiting sleeve 31.

[0044] The implementation principle of a tubular busbar connection structure of the present application embodiment is as follows: during the installation and connection of two sections of tubular busbars, the operator first sets the limiting sleeve 31 on the positioning buckles 11 of the two guide rails 1 until the positioning buckles 11 are clamped in the limiting sleeve 31; then pull the pull ring 61 and overcome the elastic force of the compression spring 5 to pull the pressure plate 32 away from the pressure plate 32, and insert the copper sheet into the limiting sleeve 31, and arrange the copper sheet through the observation hole 312; operate in the same way, and install the four copper sheets connected to the two guide rails 1 on the limiting sleeve 31 one by one; then the connecting holes 71 of the bottom of the telescopic rod 7 and the rod end are respectively set on the elastic hook 313, which further stabilizes the vertically distributed limiting sleeve 31. It not only improves the overall straightness after the two adjacent guide rails 1 are connected, but also greatly prolongs the service life of the busbar.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
