Insulator for trolley bus
Technical Field
The invention belongs to the technical field of urban trolley bus equipment, and particularly relates to a trolley bus insulator.
Background
At present, in large and medium-sized cities, a low-noise pollution-free environment-friendly direct-current 750V trolley bus is actively developed for green trip construction. The vehicle type receives a traction network power supply through two trolley poles, and due to the fact that the vehicle passes through a special traveling passage without being mixed with other vehicles on a road, the trolley poles are prone to generating wire jumping (namely the trolley poles are separated from the traction network wire) under the influence of frequent braking or the inertia effect when the vehicle emergently avoids and turns in the traveling process.
The existing trolley pole of the trolley bus is not fixed by a spacer bar, and the jumping rate is frequently generated during emergency evasion and turning in the driving process. The main reason is that the root parts of the two trolley poles used as the positive pole and the negative pole are provided with the compression springs, and the vehicle has a certain centrifugal force when emergently evading and turning, so that the two trolley poles are difficult to ensure more accurate synchronism and horizontal parallel jumping in the running process.
Disclosure of Invention
The invention aims to provide a trolley bus insulator which solves the problem that a trolley pole is easy to jump due to inertia effect when the conventional trolley bus is frequently braked or emergently evaded and turned during the running process of a vehicle.
In order to solve the above problems, the present invention discloses a trolley bus insulator, comprising:
a first collector bar;
the second trolley pole is arranged in parallel with the first trolley pole;
and one end of the composite spacing insulator is connected with the first collecting rod, and the other end of the composite spacing insulator is connected with the second collecting rod in a sliding manner.
The technical scheme of the invention also has the following characteristics:
furthermore, a first hoop is arranged on the first collecting pole, and one end of the composite spacing insulator is connected with the first hoop.
Furthermore, a plurality of second anchor ears are arranged on the second collector bar, parallel rods are arranged between the second anchor ears, sliding blocks are slidably arranged on the parallel rods, and the sliding blocks are connected with the other ends of the composite spacing insulators.
Further, the number of the second hoops is two.
Furthermore, two ends of the composite spacing insulator are respectively connected with the first hoop and the sliding block through connectors.
Further, the joint is a U-shaped joint.
Furthermore, the two connectors are respectively connected with the first hoop and the sliding block through pin rods.
Further, the side part of the sliding block is provided with an arc-shaped contact surface matched with the outer contour of the second trolley pole.
Compared with the prior art, the insulator for the trolley bus has the advantages that the two trolley poles on the trolley bus are connected together through the composite spacing insulator, so that the design can ensure that the two trolley poles cannot swing up and down under the action of inertia when the trolley bus is in emergency evasion and turning operation in the running process, the distance between the trolley poles is always kept, and the trolley poles are controlled not to be suddenly off-line; the insulator for the trolley bus has the advantages of simple overall structure, easiness in manufacturing, lower cost and better market popularization and use prospect.
