Description
Technical field
The utility model relates to underground coal mine scratch board conveyor technical fields, more specifically, are related to a kind of girdle and scrape
Plate conveyer pin rail attachment pegs.
Background technique
China achieves important breakthrough in terms of mining in combined mining thick coal seam, longwall top coal caving as producing coal base important in the world,
It in first place in the world, however is an opposite weak link in terms of thin coal bed fully-mechanized mining.Its main odjective cause is
Thin seam mining space is small, low efficiency, labor intensity of workers is big, safety accident is more, economic inefficiencies, causes a large amount of girdles
Coal resources are in and shelve state.Its key reason is to lack that adaptability is good, thin coal bed fully-mechanized mining technology of high production efficiency dress
It is standby, constrain the coordinated development of entire coal industry.
In recent years, as China's medium-thickness seam is largely exploited, Old Eastern mining area minable coal seam reserves sharply decline, and production connects
The contradiction of continuous and equilibrium of stock exploitation becomes increasingly conspicuous, and girdle high-efficiency mining problem is paid more and more attention and mentions agenda.
High to the structural requirement of drag conveyor since thin seam working surface space is small, traditional scrapper conveyor structure is difficult to meet design
It is required that.Traditional scrapper conveyor pin rail attachment pegs are that this side is mounted and dismounted from vertical plate, and girdle scrapper conveyor cable trough
It since space limits, can drop to very low, can thus block the mounting hole of pin rail attachment pegs, when replacement dismounting pin rail attachment pegs,
Cable trough must be first removed, it is very inconvenient, increase artificial and time cost.
Utility model content
The purpose of this utility model is to provide a kind of thin coal seam scraper blade conveyor of easy disassembly pin rail attachment pegs.
In order to achieve the above objectives, technical solution provided by the utility model are as follows:
A kind of thin coal seam scraper blade conveyor pin rail attachment pegs are provided with step and pin hole, the pin in the attachment pegs
Spacer pin is plugged in hole；Company is welded and fixed in the pin rail and rail chair plug connection of the drag conveyor, the rail chair and vertical plate
It connects；The pin rail and rail chair are being provided with the first jack with attachment pegs corresponding position, the vertical plate with attachment pegs corresponding position
It is provided with the second jack, the attachment pegs sequentially pass through pin rail, rail chair and vertical plate.
Further, the first jack diameter is identical as attachment pegs shank diameter, and the second jack diameter is greater than platform
Rank diameter is less than attachment pegs shank diameter.
Further, the vertical plate is provided with washer far from rail chair one end and spacer pin junction.
Compared with prior art, it is had the beneficial effect that possessed by the utility model
The utility model provides a kind of thin coal seam scraper blade conveyor pin rail attachment pegs, installs existing from vertical plate side
Method be changed to be installed from chain road side, and the fixed form of pin rail attachment pegs is improved, to reach the mesh of easy disassembly
's.The utility model uses attachment pegs, washer, spacer pin package assembly, convenient in the peace of thin seam working surface pin rail attachment pegs
Assembly and disassembly are unloaded.The fixed form of pin rail attachment pegs is fixed using washer and spacer pin, reliability enhancing.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figs. 1-5, a kind of thin coal seam scraper blade conveyor pin rail attachment pegs are provided with step 2 in the attachment pegs 1
With pin hole 3, spacer pin 5 is plugged in the pin hole 3；The pin rail 6 and 7 plug connection of rail chair of the drag conveyor, the rail
Seat 7 is welded and fixed with vertical plate 8 to be connect；The pin rail 6 is provided with the first jack with rail chair 7 and 1 corresponding position of attachment pegs, described vertical
Plate 8 sequentially passes through pin rail 6, rail chair 7 and vertical plate 8 with the second jack, the attachment pegs 1 being provided with 1 corresponding position of attachment pegs.
The first jack diameter is identical as 1 shank diameter of attachment pegs, and the second jack diameter is greater than 2 diameter of step and is less than attachment pegs
1 shank diameter.The vertical plate 8 is provided with washer 4 far from 7 one end of rail chair and 5 junction of spacer pin.
Only the preferred embodiment of the utility model is explained in detail above, but the utility model be not limited to it is above-mentioned
Embodiment can also not depart from the utility model aims within the knowledge of a person skilled in the art
Under the premise of various changes can be made, various change should be included within the scope of protection of this utility model.
