Problems solved by technology

This makes it impossible for the collector pole to fall to the safe area in a short time once there is an accident of off-line, which can easily lead to safety accidents
[0004] 2) The collector rod is directly connected to the cylinder, which is limited by the resistance of the cylinder itself. When the vehicle is driving on a bumpy road, the collector rod cannot flexibly swing up and down, and it is prone to off-line
[0005] 3) The collector rod is directly connected to the cylinder, and the range of rotation of the collector rod is limited. Maintenance and maintenance personnel have to climb to the roof to work, which is not easy to operate
[0006] 4) In order to meet the effective downforce of the collector pole and the vertical deflection angle, the stroke required by the cylinder is long, and enough space is needed for arrangement, which restricts the space of the roof

Embodiment 1

[0041] like Figure 1-2 Shown is a multi-link transmission mechanism for a collector frame provided by the first embodiment of the invention, including a base plate 1, the base plate 1 is connected with a support base 2 that can rotate relative to the base plate 1, and the support base 2 is connected with a support base 2. The boom 8 that can rotate synchronously with the support base 2 is connected with several groups of elastic members 9 between the boom 8 and the support base 2 . In this embodiment, as figure 2 As shown, a fixed seat 8-2 is provided on the top of the boom 8, and several sets of elastic members 9 are connected between the fixed seat 8-2 and the connecting seat 2-1 on the support seat 2, and the fixed seat 8-2 and the connecting seat The arrangement of 2-1 can effectively ensure the reliability and stability of the axial expansion and contraction of several groups of elastic members 9 during the use process when the elastic members 9 are stretched by the po...

Embodiment 2

[0056] Embodiment 2 of the present invention also provides a method for controlling a multi-link transmission mechanism for a collector frame, comprising the following steps:

[0057] 1) During the driving process, without touching the net, the big arm 8 is locked on the roof and kept in a horizontal state parallel to the roof, and the cylinder assembly 4 is stretched to the maximum length at this time;

[0058] 2) While the vehicle is running,

[0059] When the height of the catenary 12 from the ground increases, the catenary 12 is located above the carbon brushes 11, and the carbon brushes 11 on the boom 8 are off the screen; at this time, the piston rod of the slow-speed cylinder 4-1 is controlled to shrink inward to reduce The small cylinder assembly 4 is axially extended for a length to lift the big arm 8 upwards, thereby driving the top carbon brush 8 to be lifted synchronously and contact with the catenary 12;

[0060] When the height of the catenary 12 from the ground...

Abstract

According to the multi-connecting-rod transmission mechanism for the current collecting frame and the control method of the multi-connecting-rod transmission mechanism, compared with a three-connecting-rod transmission mechanism, a four-connecting-rod transmission mechanism and other transmission mechanisms in the prior art, amplification of transmission torque is achieved through the multi-connecting-rod structure, and the time for lowering a current collecting rod is effectively shortened; through multiple times of rotation pair transition, the stroke of the air cylinder is reduced; meanwhile, the trolley pole is in movable contact connection with the connecting rod mechanism, rotation is more flexible, the trolley pole is not limited by resistance of an air cylinder in the vehicle running process, the trolley pole can flexibly swing up and down along with the wire net, stable net touching force is kept, and wire disengaging is not prone to occurring; the overall height of the connecting rod structure is reduced, and the height limiting problem of the roof is solved; an emergency return device is arranged, so that the danger caused by accidental off-line is avoided; in addition, the axial length of the lead screw assembly is adjustable, and stable net touching force can be provided for road sections with different wire net heights; the trolley pole can be separated from the transmission connecting rod mechanism and can rotate to the position close to the ground, personnel do not need to climb to a car roof, and maintenance is convenient.

Description

technical field [0001] The invention relates to the technical field of current collectors, in particular to a multi-link transmission mechanism used for a collector and a control method thereof. Background technique [0002] At present, the common lifting mechanism of the current collector is composed of a collector rod, a cylinder connecting frame, a cylinder and a spring. The cylinder and the spring are used to control the swing of the collector rod in the vertical direction. The cylinder is pressurized and extended to drive the collector rod. The pressing action is completed; the cylinder is not pressurized, and the pulling force of the spring drives the collecting rod to complete the upward action. However, the current collecting rack lifting mechanism in the prior art still has the following defects in practical use: [0003] 1) After the cylinder stroke is completed, the collector rod is lowered, and the speed of the whole process is consistent and there is no interme...
