Description
Technical field
The utility model relates to a kind of electric locomotive and advances the sand structure.
Background technology
The existing locomotive of China advances the sand structure and mainly contains two classes: as shown in Figure 1, the first kind is that the sandbox inlet is arranged on the sandbox, and sand box cover assembly 8 is directly welded on the sandbox 9, and integral installation is applicable to that lower position advances sand on bogie truck 10 then; As shown in Figure 2, second class is that sandbox inlet is welded in the underframe side bar, forms an integral structure with the sandbox that is welded in the relevant position, is applicable to that the medium altitude position advances sand.First kind structure shown in Figure 1, because of the position limit between bogie truck 10 and the car body, the sandbox height can not be provided with too high, and sandbox is laterally, longitudinal space also is subjected to the influence that locomotive equipment is arranged, so that its capacity can not be provided with is too big; And second class formation has two defectives, the one, and sand inlet is arranged in the side bar, and opposite side load bearing beam structural strength has certain destroying infection, and another is that sand inlet can only be arranged to horizontal cross and advance sand, causes certain difficulty to advancing sand.
The utility model content
At the defective that prior art exists, the purpose of this utility model aims to provide a kind of electric locomotive and advances the sand structure, can adapt to locomotive medial side wall and advance sand, improves the height that advances sand, is fully used in the interior space of sandbox.
The utility model is that a kind of electric locomotive advances the sand structure, what comprise that advancing of offering on the car body side wall offer on sand inlet, the underframe floor advances the sand outlet and is connected between the two sand filling passageway, wherein enter the sand entrance and be provided with the sand box cover assembly that is connected on the car body side wall, underframe side bar top is fixed in the bottom of this sand box cover assembly; Described sand filling passageway by tilted-putted help stream plate, sand-feeding tube assembly and be tightly connected on the underframe floor that offers through hole with the sandbox correspondence position form; Describedly advance the sand outlet over against the sandbox inlet that is positioned at bottom, underframe floor.
Further, described stream plate one end that helps is welded in inflow point, the other end is welded in through hole edge one side that is provided with on the underframe floor, and sand-feeding tube assembly one end is welded in sand box cover assembly upper rear end, and the other end is welded in the through hole edge opposite side that is provided with on the underframe floor.
Electric locomotive described in the utility model advances in the sand structure, and the bottom of sand box cover assembly is directly welded in car body side bar top, by car body side bar support fixation; Sand box cover assembly rear end is directly welded in the downside that advances the sand inlet that is provided with on the car body side wall.Sand box cover assembly rear end lower helps the stream plate by welding setting, helps the stream plate other end to be welded in the through hole inflow point that offers on the underframe floor.Sand-feeding tube assembly one end also is welded in sand box cover assembly upper rear end, promptly advances the upside and the left and right sides of sand inlet, simultaneously its with help stream plate and the underframe floor cavity structure that is welded, as advancing the sand inlet and the sand filling passageway between the outlet of shaking out.Sandbox is welded in cooresponding floor of the through hole of offering on the underframe floor and side bar position.Like this, this advances sand structure and sandbox and has formed the band sand inlet of a no gap welding and the cavity body structure of sand export jointly.
Described side wall advances the sand structure and is fixedly welded on the car body with car body side wall, underframe side bar and underframe floor respectively by each parts, make sandbox can use the underframe floor as its top cover, seamlessly be welded in the relevant position of underframe, thereby form the system that a single-piece advances sand, stores up sand, shakes out.Sand enters sand filling passageway from the sand entrance of advancing that is provided with the sand box cover assembly, slips over bevelled and helps the stream plate, and the through hole that is provided with in the underframe floor enters into sandbox.Be positioned at the underframe floor owing to advance the sand outlet, be positioned at the sandbox top fully, sand can fill whole sandbox, compared with prior art, has increased the capacity of sandbox.
The technique effect that the utility model can reach is:
1, can make full use of the available space of sandbox top;
2, the overall volume that can 100% makes full use of sandbox;
3, it is more smooth and easy to make sand enter sandbox, and it is convenient more to advance sand.

The specific embodiment
As shown in Figure 3, present embodiment is described to advance the sand structure, what comprise that advancing of offering on the car body side wall offer on sand inlet, the underframe floor advances the sand outlet and is connected between the two sand filling passageway, wherein enter the sand entrance and be provided with the sand box cover assembly 1 that is connected on the car body side wall 5, the bottom support fixation of this sand box cover assembly 1 is in underframe side bar 6 tops; Described sand filling passageway by tilted-putted help stream plate 3, sand-feeding tube assembly 2 and be tightly connected on the underframe floor 7 that offers through hole with sandbox 4 correspondence positions form; Describedly advance the sand outlet over against the sandbox inlet that is positioned at 7 bottoms, underframe floor.
During application, sand box cover assembly 1 bottom is directly welded in the top of underframe side bar 6, sand box cover assembly 1 side be directly welded in offer on the car body side wall 5 enter the sand entrance.Sand box cover assembly 1 rear end lower helps stream plate 3 by welding setting, and described stream plate 3 one ends that help are welded in inflow point, and the other end is welded in through hole edge one side that is provided with on the underframe floor 7.Sand-feeding tube assembly 2 one ends are welded in sand box cover assembly upper rear end, and the other end is welded in the through hole edge opposite side that is provided with on the underframe floor 7.Described sand-feeding tube assembly 2 welds the formation cavity structures as sand filling passageway with helping stream plate 3.Sandbox 4 is welded in 7 bottoms, underframe floor.Like this, this advances sand structure and sandbox 4 and has formed the band sand inlet of a no gap welding and the cavity body structure of sand export.Therefore, sandbox 4 can be used the underframe floor as its top cover, seamlessly is welded in the relevant position of underframe, thereby forms the system that a single-piece advances sand, stores up sand, shakes out.
During work, sand enters sand-feeding tube assembly 2 from the sand entrance of advancing that is provided with sand box cover assembly 1, helps stream plate 3 through bevelled, enters into sandbox 4.Because this sand outlet of advancing of advancing the sand structure is positioned at sandbox 4 tops fully, so sand can fill whole sandbox 4.Originally advance the available space that the sand structure can make full use of sandbox 4 tops, make full use of the overall volume of sandbox 4, owing to adopted bevelled to help the stream plate to make sand can enter sandbox more swimmingly.
