Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of urban trolleybus equipment, and particularly relates to a trolleybus insulator. Background Art
[0002] Currently, in order to build a green travel mode in large and medium-sized cities, environmentally friendly DC 750V trolleybuses with low noise and no pollution are actively developed. This type of vehicle receives the traction network power through two pantographs. Since there is no dedicated driving lane for this vehicle and it travels mixed with other means of transportation on the road, when braking frequently or the vehicle makes an emergency avoidance or turn during driving, due to the inertial effect, the pantographs are prone to jumping wires (i.e., the pantographs are separated from the traction network wires).
[0003] Existing trolleybus pantographs are not fixed with spacer dampers, and wire jumping often occurs during emergency avoidance and turning while driving. The main reason is that compression springs are installed at the roots of the two pantographs used as positive and negative electrodes. When the vehicle makes an emergency avoidance and turn, there is a certain centrifugal force, so it is difficult to ensure precise synchronization and horizontal parallel jumping of the two pantographs during operation. Summary of the Invention
[0004] The purpose of the present invention is to provide a trolleybus insulator to solve the problem that in existing trolleybuses, due to the inertial effect, the pantographs are prone to jumping wires when braking frequently or the vehicle makes an emergency avoidance or turn during driving.
[0005] To solve the above problems, the present invention discloses a trolleybus insulator, including:
[0006] A first pantograph;
[0007] A second pantograph, the second pantograph is arranged in parallel with the first pantograph;
[0008] A composite spacer insulator, one end of the composite spacer insulator is connected to the first pantograph, and the other end is slidably connected to the second pantograph.
[0009] The technical solution of the present invention further has the following characteristics:
[0010] Further, a first clamp is provided on the first pantograph, and one end of the composite spacer insulator is connected to the first clamp.
[0011] Further, a plurality of second clamps are provided on the second pantograph, a parallel rod is arranged between the plurality of second clamps, a slider is slidably arranged on the parallel rod, and the slider is connected to the other end of the composite spacer insulator.
[0012] Further, the number of the second clamps is two.
[0013] Furthermore, both ends of the composite spacer insulator are respectively connected to the first clamp and the slider through connectors.
[0014] Furthermore, the connector is a U-shaped connector.
[0015] Furthermore, the two connectors are respectively connected to the first clamp and the slider through pin rods.
[0016] Furthermore, an arc-shaped contact surface matching the outer contour of the second current collector pole is arranged on the side of the slider.
[0017] Compared with the prior art, the principle of a trolleybus insulator of the present invention is that two current collector poles on the trolleybus are connected together through a composite spacer insulator. Such a design can ensure that when the trolleybus makes emergency avoidance and turning operations during driving, the two current collector poles will not swing up and down under the action of inertia, always maintaining the distance between the current collector poles and controlling the current collector poles from suddenly going offline; this trolleybus insulator has a simple overall structure, is easy to manufacture, has a low cost, and has a good market promotion and application prospect.

[0021] The following will cooperate with embodiments to detail the implementation manners of the present invention, so as to fully understand how the present invention applies technical means to solve technical problems and achieve the realization process of technical effects and implement accordingly.
[0022] As Figure 1 shown, a trolleybus insulator of the present invention includes:
[0023] A first current collector pole 1;
[0024] A second current collector pole 6, and the second current collector pole 6 is arranged in parallel with the first current collector pole 1;
[0025] A composite spacer insulator 4, one end of the composite spacer insulator 4 is connected to the first current collector pole 1, and the other end is slidably connected to the second current collector pole 6.
[0026] As Figure 1 shown, compared with the prior art, the principle of a trolleybus insulator of the present invention is that the two current collector poles on the trolleybus (i.e., the first current collector pole 1 and the second current collector pole 6) are connected together through the composite spacer insulator 4. Such a design can ensure that when the trolleybus makes emergency avoidance and turning operations during driving, the two current collector poles will not swing up and down due to inertia, always maintaining the distance between the current collector poles and controlling the current collector poles from suddenly going offline.
[0027] As Figure 1 shown, in a trolleybus insulator of the present invention, a first clamp 2 is provided on the first current collector pole 1, and one end of the composite spacer insulator 4 is connected to the first clamp 2.
[0028] After the first clamp 2 is sleeved on the first current collector pole 1 and fastened by bolts, then one end of the composite spacer insulator 4 is connected to the first clamp 2. Such a design facilitates the rapid assembly between the composite spacer insulator 4 and the first current collector pole 1.
[0029] As Figure 1 shown, in a trolleybus insulator of the present invention, a plurality of second clamps 9 are provided on the second current collector pole 6, a parallel rod 8 is provided between the plurality of second clamps 9, a slider 7 is slidably provided on the parallel rod 8, and the slider 7 is connected to the other end of the composite spacer insulator 4.
[0030] As a preferred sliding installation method between the composite spacer insulator 4 and the second current collector pole 6, a plurality of second clamps 9 can be sleeved on the second current collector pole 6, and then the second clamps 9 are fastened with bolts. The parallel rod 8 is installed between the plurality of second clamps 9, and a slider 7 is sleeved on the parallel rod 8. The slider 7 is connected to the other end of the composite spacer insulator 4, and the sliding installation between the composite spacer insulator 4 and the second current collector pole 6 can be realized. This assembly method can ensure that the composite spacer insulator 4 can slide within a certain small range with the second current collector pole 6 as the reference to ensure that the first current collector pole 1 and the second current collector pole 6 always maintain a certain distance.
[0031] As Figure 1 shown, in a trolleybus insulator of the present invention, the number of the second clamps 9 is two.
[0032] Both ends of the parallel rod 8 are respectively arranged in the two second clamps 9. On the one hand, it can ensure the stability after installation, and on the other hand, it can reserve a large installation space for the assembly of the slider 7 to ensure that it can slide within a certain range.
[0033] As Figure 1 shown, in a trolleybus insulator of the present invention, both ends of the composite spacer insulator 4 are respectively connected to the first clamp 2 and the slider 7 through the joint 3, which facilitates quick assembly and also facilitates later maintenance and replacement.
[0034] As Figure 1 shown, in a trolleybus insulator of the present invention, the joint 3 is a U-shaped joint, and the two joints 3 are respectively connected to the first clamp 2 and the slider 7 through the pin rod 5, which facilitates quick replacement.
[0035] As Figure 1 shown, in a trolleybus insulator of the present invention, an arc-shaped contact surface matching the outer contour of the second current collector rod 6 is provided on the side of the slider 7.
[0036] The side of the slider 7 is closely attached to the outside of the second current collector rod 6, which can ensure the stability of the sliding of the slider 7.
[0037] In summary, a trolleybus insulator of the present invention has a simple overall structure, is easy to manufacture, has a low cost, and has a good market promotion and application prospect.
