Abstract
The utility model relates to a mining technical field, in particular to scraper conveyor's compound C type groove middle part groove of high strength, including C type groove and ledge subassembly, C type groove sets up on the ledge subassembly, is provided with on the C type groove to fix a position the strip with ledge subassembly complex. Compared with the prior art, the utility model discloses a medium plate subassembly sets up the structure on the ledge subassembly, and the medium plate subassembly is independent structure, when the wearing and tearing of medium plate subassembly are serious, can change the medium plate subassembly, that shovels equally that the card slot is able to help the setting shovels coal board wearing and tearing when serious, the board of shoveling coal more renewed after also can taking off. Change the medium plate subassembly and shoveled coal the middle part groove performance of board and resumeed new middle part groove basically.
Description
Technical field
This utility model relates to mining technique field, particularly to the high-strength composite C-shaped channel intermediate channel of drag conveyor.
Background technology
The version of current domestic intermediate channel is mainly cast-welded structure, mainly by: baffle, shovel board ledge, middle plate, base plate, rack rails holder assembly form.
Coal under adopting due to coal-winning machine, spoil etc. fully fall in intermediate channel, directly contact with middle plate, then run in intermediate channel with the scraper chain of movement.Frictional force suffered by middle plate is very big, and constantly moves in circles, so abrasion can be the most serious.Current domestic middle plate used only has one layer, non-exchange, can only repair by built-up welding after the abrasion of middle plate.
At another, the place of serious wear is shovel board, and shovel board ledge is integrally cast with ledge by shovel board.The piston shoes of coal-winning machine move back and forth in shovel board, and the two rubs sassafras for slip.Therefore shovel board serious wear, also can only lean on Bead weld repair after the abrasion of current shovel board.
Although built-up welding can make up surface abrasion, but facing surface is of poor quality, and effect is the most undesirable, and the intensity of intermediate channel can be caused to reduce, the problem such as distort.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 major part intermediate channel, plate and the equal wear extent of shovel board too much need to repair, and use large-area built-up welding to waste time and energy.
Utility model content
The purpose of this utility model is to provide the high-strength composite C-shaped channel intermediate channel that a kind of comprehensive cost is low, anti-wear performance is good.
The purpose of this utility model is achieved in that
High-strength composite C-shaped channel intermediate channel, including C-shaped channel, ledge assembly and rack rails holder assembly, C-shaped channel is arranged on ledge assembly, and C-shaped channel is provided with the positioning strip coordinated with ledge assembly.
Ledge assembly includes baffle and shovel board ledge and the lower middle plate being arranged between and base plate.
The two ends of base plate, for tilting structure, so can increase the contact area with scraper plate, reduces ratio pressure, reduces abrasion.
Ramp plate and upper coal plate it is provided with on the shovel board ledge of ledge assembly.
Ramp plate covers on shovel board ledge, simple in construction, and it is convenient to change.
Upper coal plate is tiltedly placed on shovel board ledge, for increasing the intensity of shovel board ledge, improves effect of loading coal.
C-shaped channel includes middle plate and is arranged on the ledge edge at two ends above middle plate, increases the lap width between intermediate channel, it is to avoid leak coal between groove, and ledge is provided with positioning strip on edge, and positioning strip is arranged on ledge edge is easy to processing.
Ledge is along being structure as a whole or multistage splicing construction, and when using multistage splicing construction, because the abrasion at two ends is more serious, two ends use more preferable wearability material, and the wearability on such ledge edge is more preferable.
Positioning strip is that a whole piece is arranged on ledge along upper, or positioning strip is that at least two segments are disposed on ledge along upper.
Relative to prior art, during this utility model uses, board component is arranged on the structure on ledge assembly, and middle board component is independent structure, during central board component serious wear, and board component in can changing；During the ramp plate serious wear arranged on same shovel board ledge, it is also possible to the ramp plate more renewed after taking off.In changing, the intermediate channel performance of board component and ramp plate substantially returned to new intermediate channel.

Detailed description of the invention
As shown in figs 1 to 6, high-strength composite C-shaped channel intermediate channel, including C-shaped channel 1 and ledge assembly 2, C-shaped channel 1 is arranged on ledge assembly 2, and C-shaped channel 1 is provided with the positioning strip 5 coordinated with ledge assembly 2.
Ledge assembly 2 includes baffle 6 and shovel board ledge 9 and the lower middle plate 7 being arranged between and base plate 8.
The two ends of base plate 8, for tilting structure, so can increase the contact area with scraper plate, reduces ratio pressure, reduces abrasion.
It is provided with ramp plate 10 on the shovel board ledge 9 of ledge assembly 2.Ramp plate 10 covers on shovel board ledge, simple in construction, and it is convenient to change.
It is provided with coal plate on the shovel board ledge 9 of ledge assembly 2.Upper coal plate is tiltedly placed on shovel board ledge 9, for increasing the intensity of shovel board ledge 9, improves effect of loading coal.
C-shaped channel 1 includes middle plate 3 and is arranged on the ledge at the two ends lap width along 4, between increase intermediate channel above middle plate 3, it is to avoid leaking coal between groove, ledge is provided with positioning strip 5 along 4, and positioning strip 5 is arranged on ledge and is easy to processing along 4.Ledge is structure as a whole along 4 or multistage splicing construction, and when using multistage splicing construction, because the abrasion at two ends is more serious, two ends use more preferable wearability material, and such ledge is more preferable along the wearability of 4.
Positioning strip 5 is that a whole piece is arranged on ledge along 4, or positioning strip 5 is that at least two segments are disposed on ledge along 4, use two segment positioning strips 5 be arranged on ledge along 4 time, positioning strip 5 is arranged on the two ends that ledge is along 4.
