Abstract
The utility model relates to pantograph fault protective control equipment for an electric locomotive, in particular to a control box of an air spring type automatic pantograph descending system of an electric locomotive. According to the control box, a cut-out cock is connected to a lateral surface in the control box by using a bolt, one end of the cut-out cock penetrates through a hole on the lateral surface of the control box and is communicated with a bow head, and the other end of the cut-out cock is connected with a control valve fixed on the bottom surface of the control box through a gas path hose; and the control valve is communicated with an interface of a three-way valve seat on the bottom surface of the control box, one of the other two interfaces is communicated with a gas source control system outside the control box, and the other interface is connected with an air spring. The control box has the advantages that components are integrated and arranged in the control box, so that the working environment of the components is effectively improved; and the control system is separated from the gas source control system, so that mutual interference between the two systems is reduced, and the working stability and the working efficiency of the systems are improved. The control box is applicable to a pantograph of the electric locomotive.
Description
(1) technical field
The utility model relates to a kind of block of bow collector of electric locomotive emergency protection control convenience, specifically a kind of electric locomotive air spring type pantograph automatic bow-lowering system control box.
(2) background technology
Present domestic employed air spring type pantograph automatic bow-lowering system, its components and parts are directly installed on the pantograph underframe, protect without casing.Or components and parts and gas source control system integrate, and system can not independently install, therefore, on the working stability of components and parts protection and system relatively a little less than.
(3) utility model content
The purpose of this utility model is to provide a kind of can either protect components and parts, can make again the stability-enhanced a kind of electric locomotive air spring type pantograph automatic bow-lowering system control box of system works.
For achieving the above object, the utility model is realized in the following manner: the utility model comprises: control box, gas path pipe, joint, captive nut, the utility model is that cut out cock is connected on the side in the control box with captive nut, pass the hole of one end from the control box side with bow outside the control box and be connected, the other end of cut out cock is connected with control cock on being fixed on the control box inner bottom surface by the gas circuit flexible pipe, control cock links with an interface that is located at the threeway valve seat on the control box inner bottom surface with connecing fiber tube, the outer gas source control system of one two other interface and control box links, and one is connected with air bellow.
The utility model has the advantage of all components and parts of system are integrated to be installed in the control casing, can Effective Raise the degree of protection of components and parts, improve the working environment of components and parts, increased the service life of components and parts.Control system and gas source control system are installed separately, thereby have reduced the phase mutual interference between two systems, have strengthened the working stability of system, have improved the work efficiency of whole system.It is useful on the block of bow collector of electric locomotive and uses.
(4) description of drawings
Accompanying drawing is structural representation of the present utility model.
1-control box, 2-cut out cock, 3-control cock, 4-threeway valve seat
(5) specific embodiment
Below in conjunction with embodiment the utility model is described in further detail:
The utility model comprises: control box, gas path pipe, joint, captive nut, the utility model is that cut out cock (2) is fixed on the interior side of control box (1) with captive nut, pass the hole of one end from control box (1) side with bow outside the control box (1) and be connected, the other end of cut out cock (2) is connected with control cock (3) on being fixed on control box (1) inner bottom surface by the gas circuit flexible pipe, control cock (3) links with an interface that is located at the threeway valve seat (4) on control box (1) inner bottom surface with connecing fiber tube, the outer gas source control system of one two other interface and control box (1) links, and one is connected with air bellow.
