Technical Field

The invention relates to a low-cost safety trolley bow which is mainly applied to the field of connection equipment of cables and electric locomotives of mine trolley locomotives.

Background

The contact pressure of overhead line direct current electric locomotive pantograph sliding friction has greatly increased pantograph and overhead line, has shortened the life-span of overhead line and pantograph, increases manufacturing cost, and direct current electric locomotive is turning or when reverse simultaneously, need follow the car worker manual control pantograph, and manual control is to the suitable position ten minutes difficulty, and this brings very big difficulty with the car worker, has very big potential safety hazard.

Disclosure of Invention

The technical problem to be solved by the invention is as follows: the low-cost safe trolley pantograph has the advantages of simple structure, reliable work, prolonged service life of the overhead line and the pantograph, reduced production cost and safe use.

The invention relates to a low-cost safety trolley pantograph which comprises a left guard plate and a right guard plate, wherein a pantograph body is arranged between the top ends of the left guard plate and the right guard plate through a rotating shaft, the bottoms of the left guard plate and the right guard plate are arranged on a bottom plate, two support columns are arranged at the bottom of the bottom plate, the two support columns are arranged on a cross shaft through mounting blocks, supports are arranged at two ends of the cross shaft and are connected with a trolley connecting plate, a supporting spring is arranged on the cross shaft and is positioned between the two mounting blocks, two ends of the supporting spring are respectively connected with a first stop lever and a second stop lever, the first stop lever and the second stop lever are respectively positioned at the upper side and the lower side of the cross shaft, the first stop lever is fixed between the two support columns, the second stop lever is fixed in the supports, an up-down adjusting device is arranged in the supports, the supports comprise.

Because the pantograph is arranged between the left protective plate and the right protective plate through the rotating shaft, rolling friction is generated when the pantograph is in contact with the overhead line, the original sliding friction is changed, the friction between the pantograph and the overhead line is reduced, the friction force between the pantograph and the overhead line is smaller, and the service lives of the pantograph and the overhead line are prolonged; and a cross shaft is arranged between the support and the pillar, and a supporting spring is arranged on the cross shaft, so that the angle between the support and the pillar can be adjusted after the support and the pillar are stressed, the damage is reduced, the service life is prolonged, the direction is convenient to adjust, and the use safety can be improved.

The invention has the beneficial effects that:

the structure is simple and reasonable, the operation is reliable, the service life of the overhead line and the pantograph can be prolonged, the production cost is reduced, the automatic reversing can be realized, the use and the maintenance are convenient, and the like.

Drawings

Fig. 1 is a schematic structural view of the present invention.

In the figure: 1. the device comprises a pantograph 2, a left guard plate 3, a bottom plate 4, a pillar 5, a transverse shaft 6, a longitudinal rod 7, a transverse rod 8, an electric locomotive connecting plate 9, a second stop rod 10, a mounting block 11, a support spring 12, a first stop rod 13 and a right guard plate.

Detailed Description

The invention is further described below with reference to the accompanying drawings:

as shown in fig. 1, the low-cost safety trolley pantograph according to the invention comprises a left guard plate 2 and a right guard plate 13, wherein a pantograph 1 is installed between the top ends of the left guard plate 2 and the right guard plate 13 through a rotating shaft, the bottoms of the left guard plate 2 and the right guard plate 13 are installed on a bottom plate 3, two support columns 4 are arranged at the bottom of the bottom plate 3, the two support columns 4 are installed on a cross shaft 5 through installation blocks 10, supports are arranged at two ends of the cross shaft 5 and connected with a trolley connecting plate 8, a support spring 11 is arranged on the cross shaft 5, the support spring 11 is positioned between the two installation blocks 10, two ends of the support spring 11 are respectively connected with a first stop lever 12 and a second stop lever 9, the first stop lever 12 and the second stop lever 9 are respectively positioned at the upper side and the lower side of the cross shaft 5, the first stop lever 12 is fixed. The support includes horizontal pole 7 and vertical pole 6, sets up the through-hole on the vertical pole 6, and the cross axle 5 passes through the axle sleeve to be installed in the through-hole, and electric locomotive connecting plate 8 is connected to horizontal pole 7.

The pantograph 1 generates rolling friction when contacting with the overhead line, changes the original sliding friction, and reduces the current collection

The bow 1 rubs with the overhead line, so that the friction force between the bow 1 and the overhead line is small, and the service life of the bow and the overhead line is prolonged. The column 4 is freely rotatable about the transverse axis 5 under the control of the stay spring 11 for adjusting the angle and direction.
