Abstract
A kind of compound intermediate channel of replaceable middle plate, comprise baffle, shovel board ledge, middle plate, base plate, it is characterized in that: the two ends of middle plate are respectively baffle and shovel board ledge, middle plate is made up of upper plate and lower middle plate, shovel board ledge is made up of shovel board and ledge, between upper plate with lower middle plate, is all connected with Type of Welding between shovel board with ledge.Not only in the utility model, plate serious wear needs when repairing only to need upper plate to take off, and the wear plate more renewed welds again, reduces maintenance cost but also substantially increases service life of compound intermediate channel; Shovel board welds one block of high-strength wearable plate on original casting ledge, decreases the abrasion loss of slipper of coal producer to shovel board, substantially increases the service life of shovel board, and only needs new of shovel board to replace during serious wear.
Description
Technical field
The utility model relates to mining technique field, particularly a kind of compound intermediate channel of replaceable middle plate.
Background technology
The structural shape mainly cast-welded structure of current domestic intermediate channel, primarily of: the compositions such as baffle, shovel board ledge, middle plate, base plate, rack rails holder assembly.
Due to coalcutter adopt under coal, spoil etc. all drop in intermediate channel, directly contact with middle plate, the scraper chain then with movement runs in intermediate channel.Therefore the friction force suffered by middle plate is very large, and constantly circulation repeatedly, can be very serious so wear and tear.Current domestic middle plate used only has one deck, non-exchange, can only repair after middle plate wearing and tearing by built-up welding.
The place of another place's serious wear is shovel board, and shovel board ledge is formed by shovel board and ledge inblock cast.The piston shoes of coalcutter back and forth use in shovel board, and the two is cliding friction.Therefore shovel board serious wear, also can only lean on Bead weld repair after current shovel board wearing and tearing.
Although built-up welding can make up surface abrasion, facing surface is of poor quality, and effect is very undesirable, and the intensity of intermediate channel can reduce.And intermediate channel quantity is many, middle plate area is wide, when equipment complete a certain amount of coal mining task need overhaul time, in most of intermediate channel, plate and the equal abrasion loss of shovel board too much need to repair, and adopt large surface build-up welding to waste time and energy.
Utility model content
The purpose of this utility model is to provide the compound intermediate channel of the replaceable middle plate that a kind of expense is low, wear resisting property is good.
For achieving the above object, by the following technical solutions:
A kind of compound intermediate channel of replaceable middle plate, comprise baffle, shovel board ledge, middle plate, base plate, the two ends of middle plate are respectively baffle and shovel board ledge, middle plate is made up of upper plate and lower middle plate, shovel board ledge is made up of shovel board and ledge, between upper plate with lower middle plate, is all connected with Type of Welding between shovel board with ledge.
In baffle and ledge, plate is provided with the breach matched with upper plate cross-sectional plane along position.
Shovel board ledge is provided with the groove matched with shovel board.
Upper plate, shovel board have been evenly arranged through hole.
Not only middle plate of the present utility model, by original monoblock high-strength wearable plate, is divided into common plate and high-strength wearable plate, ensure that result of use but also greatly reduce material cost; In the middle of plate serious wear need when repairing only to need upper plate to take off, not only the wear plate more renewed welds again, reduces maintenance cost but also substantially increases service life of compound intermediate channel; Shovel board welds one block of high-strength wearable plate on original casting ledge, decreases the abrasion loss of slipper of coal producer to shovel board, substantially increases the service life of shovel board, and only needs new of shovel board to replace during serious wear.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the enlarged drawing of A1 in Fig. 1.
Fig. 3 is the enlarged drawing of A2 in Fig. 1.
Fig. 4 is the birds-eye view of Fig. 1.
Wherein: 1 baffle, 2 upper plates, plate in 3 times, 4 base plates, 5 ledges, 6 shovel boards, 7 breach, 8 through holes.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of compound intermediate channel of replaceable middle plate, comprise baffle 1, shovel board ledge, middle plate, base plate 4, the two ends of middle plate are respectively baffle and shovel board ledge, middle plate is made up of upper plate 2 and lower middle plate 3, shovel board ledge is made up of shovel board 6 and ledge 5, between upper plate with lower middle plate, is all connected with Type of Welding between shovel board with ledge.In baffle and ledge, plate is provided with the breach 7 matched with middle plate cross-sectional plane along position.Shovel board ledge is provided with the groove matched with shovel board.Upper plate, shovel board have been evenly arranged through hole 8.Upper plate is high-strength wearable plate, and lower middle plate is common plate, and the thickness of upper plate is less than the thickness of lower middle plate.
If upper plate and shovel board serious wear, then the attachment weld of upper plate and shovel board can be dug and open, renew, avoid the surface deficiency of original built-up welding, raise the efficiency.Shovel board and ledge split, no longer integrally cast with ledge, shovel board can be used wear-resistant material separately, strengthens wear resisting property.The through hole that upper plate and shovel board are arranged, as shown in the through hole 8 in Fig. 4, can effectively prevent plate and shovel board in after welding from producing distortion such as " bulges ", increase bonding area, strengthening connects.In addition, the upper plate of material of middle plate is wear-resistant material, and lower middle plate is common sheet material, and the thin lower middle thickness of slab of upper plate, all uses wear-resistant material cost-saving than whole middle plate like this.
