Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, specifically to a chassis vehicle transmission structure. Background Technology

[0002] In existing withdrawable switchgear, in order to facilitate the advancement and withdrawal of circuit breakers, a chassis is generally used to carry circuit breakers and other components. In the chassis transmission mechanism, a motor transmits power to a gear fixed to a transmission rod through a gear, which drives the transmission rod to rotate. The transmission rod moves axially, thereby driving the wheels of the chassis to rotate.

[0003] In traditional chassis vehicle transmission structures, all transmission components are fixedly installed inside the chassis vehicle. When maintenance or repair of the transmission components is required, the entire chassis vehicle must be disassembled, and the transmission components must be removed from the chassis vehicle for maintenance. The operation process is cumbersome and laborious, which greatly affects work efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a chassis transmission structure to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0006] This utility model provides a chassis transmission structure, including a chassis and transmission rods. Two transmission rods are arranged parallel to each other on both sides of the chassis interior. Both ends of the two transmission rods are rotatably connected to the inner wall of the chassis via first rolling bearings. A support plate is fixedly installed inside the chassis on the side closest to the two transmission rods. A rotating rod is rotatably installed inside the support plate. A first bevel gear is fixedly sleeved at the end of the rotating rod near the transmission rod, and a second bevel gear is fixedly sleeved at one end of the transmission rod. The first and second bevel gears mesh with each other. The directions are all opposite. An opening is provided in the middle of the chassis. A cover plate is provided on the outer side of the opening. Two horizontal plates are fixedly provided on the upper surface of the cover plate. A drive rod is rotatably provided between one side of the two horizontal plates. A first square hole is provided at both ends of the drive rod. A square rod is slidably provided inside the first square hole. A second square hole is provided at the end of the rotating rod near the drive rod. One end of the second square hole extends into the corresponding second square hole. A transmission mechanism for driving the drive rod to rotate is provided in the middle of the upper surface of the cover plate. A limiting mechanism for restricting the movement of the square rod is provided on the upper surface of the chassis.

[0007] Preferably, the transmission mechanism includes a first spur gear and a second spur gear. A vertical plate is fixedly disposed in the middle of the upper surface of the cover plate, and a mounting rod is rotatably disposed on one side of the vertical plate. The first spur gear is fixedly sleeved on the wall of the mounting rod, and the second spur gear is fixedly sleeved on the wall of the drive rod. The first spur gear and the second spur gear are meshed and connected. A motor is fixedly disposed at the end of the vertical plate away from the mounting rod, and the output end of the motor is fixedly connected to one end of the mounting rod.

[0008] Preferably, the limiting mechanism includes an iron plate and an electromagnet. The iron plate is disposed on the side of the horizontal plate near the transmission rod. The middle end of the square rod is rotatably sleeved inside the iron plate through a second rolling bearing. A limiting rod is movably sleeved inside one end of the horizontal plate. One end of the limiting rod is fixedly connected to the iron plate. The electromagnet is fixedly disposed on the upper surface of the chassis and located on the edge of the opening near the transmission rod. The electromagnet is magnetically connected to the iron plate.

[0009] Preferably, a stop is fixedly provided at the end of the limiting rod away from the iron plate, and a spring is movably sleeved on the rod wall of the limiting rod, with the two ends of the spring being fixedly connected to the corresponding horizontal plate and the stop, respectively.

[0010] Preferably, the four corners of the cover plate are all bolted to the chassis and threadedly locked.

[0011] Preferably, a sealing gasket is provided on the side of the cover plate near the chassis.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The motor drives the drive rod to rotate via the first and second spur gears. The drive rod drives the two square rods to rotate, which in turn drives the two rotating rods to rotate. The two rotating rods drive the corresponding first bevel gears to rotate. The two first bevel gears in opposite directions drive the two second bevel gears in opposite directions to rotate, which in turn drives the two second bevel gears to rotate in the same direction. This allows the two transmission rods to rotate in the same direction, thus enabling normal chassis transmission.

[0014] 2. Disconnect the power supply by using the electromagnet. At this time, the spring pushes the stop block to move away from the corresponding horizontal plate, so that the limit rod moves the iron plate away from the corresponding electromagnet, so that the square rod leaves the second square hole. At this time, loosen several bolts to separate the cover plate from the chassis, so that the transmission components can be quickly removed for maintenance and repair without disassembling the entire chassis. The operation is convenient, time-saving and labor-saving. Attached Figure Description

[0019] A chassis transmission structure, such as Figure 1-3 As shown, the system includes a chassis 1 and two transmission rods 2. Two transmission rods 2 are arranged parallel to each other on both sides of the interior of the chassis 1. Both ends of the two transmission rods 2 are rotatably connected to the inner wall of the chassis 1 via first rolling bearings. A support plate 7 is fixedly installed inside the chassis 1 on the side closest to the two transmission rods 2. A rotating rod 8 is rotatably installed inside the support plate 7. A first bevel gear 9 is fixedly sleeved at one end of the rotating rod 8 near the transmission rod 2, and a second bevel gear 10 is fixedly sleeved at one end of the transmission rod 2. The first bevel gear 9 and the second bevel gear 10 are meshed and connected. The directions of the two first bevel gears 9 and the second bevel gear 10 are opposite. The chassis 1... An opening is provided in the middle, and a cover plate 3 is provided on the outer side of the opening. The four corners of the cover plate 3 are threadedly connected to the chassis 1 by bolts 18, which makes it easy to remove the cover plate 3. A sealing gasket is provided on the side of the cover plate 3 near the chassis 1 to improve the sealing between the cover plate 3 and the chassis 1. Two horizontal plates 4 are fixedly provided on the upper surface of the cover plate 3. A drive rod 5 is rotatably provided between one side of the two horizontal plates 4. A first square hole is provided at both ends of the drive rod 5. A square rod 6 is slidably provided inside the first square hole. A second square hole is provided at the end of the rotating rod 8 near the drive rod 5. One end of the second square hole extends into the corresponding second square hole.

[0020] like Figure 1-3 As shown, a transmission mechanism for driving the drive rod 5 to rotate is provided in the middle of the upper surface of the cover plate 3. The transmission mechanism includes a first spur gear 14 and a second spur gear 13. A vertical plate 11 is fixedly provided in the middle of the upper surface of the cover plate 3. An installation rod 12 is rotatably provided on one side of the vertical plate 11. The first spur gear 14 is fixedly sleeved on the rod wall of the installation rod 12, and the second spur gear 13 is fixedly sleeved on the rod wall of the drive rod 5. The first spur gear 14 and the second spur gear 13 are meshed and connected. A motor 15 is fixedly provided at the end of the vertical plate 11 away from the installation rod 12. The output end of the motor 15 is fixedly connected to one end of the installation rod 12.

[0021] like Figure 1-3 As shown, a limiting mechanism for restricting the movement of the square rod 6 is provided on the upper surface of the chassis 1. The limiting mechanism includes an iron plate 16 and an electromagnet 17. The iron plate 16 is located on the side of the horizontal plate 4 near the transmission rod 2. The middle end of the square rod 6 is rotatably sleeved inside the iron plate 16 through a second rolling bearing. A limiting rod 19 is movably sleeved inside one end of the horizontal plate 4. One end of the limiting rod 19 is fixedly connected to the iron plate 16. The electromagnet 17 is fixedly located on the upper surface of the chassis 1 and is located on the edge of the opening near the transmission rod 2. The electromagnet 17 is magnetically connected to the iron plate 16.

[0022] like Figure 1-3 As shown, a stop block 20 is fixedly installed at the end of the limiting rod 19 away from the iron plate 16, and a spring 21 is movably sleeved on the rod wall of the limiting rod 19. The two ends of the spring 21 are fixedly connected to the corresponding horizontal plate 4 and the stop block 20 respectively, so that the limiting rod 19 can drive the iron plate 16 to reset.

[0023] In summary: During use, the motor 15 drives the drive rod 5 to rotate via the transmission of the first spur gear 14 and the second spur gear 13. The drive rod 5 drives the two square rods 6 to rotate, which in turn drives the two rotating rods 8 to rotate. The two rotating rods 8 drive the corresponding first bevel gears 9 to rotate. The two first bevel gears 9 in opposite directions drive the two second bevel gears 10 in opposite directions to rotate, which in turn drives the two second bevel gears 10 to rotate in the same direction. This allows the two transmission rods 2 to rotate in the same direction, enabling normal chassis transmission. When maintaining the transmission components, the electromagnet 17 is disconnected from the power supply. At this time, the spring 21 pushes the stop block 20 to move away from the corresponding cross plate 4, which causes the limit rod 19 to drive the iron plate 16 to move away from the corresponding electromagnet 17. This causes the square rods 6 to leave the second square hole. At this time, loosening the bolts 18 allows the cover plate 3 to be separated from the chassis 1, allowing the transmission components to be quickly removed for maintenance and repair without disassembling the entire chassis. This operation is convenient, time-saving, and labor-saving.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
