The cable duct spillplate that non-bolt connects
Technical field
The utility model relates to the improvement of cable duct spillplate structure on the coal-cutting machinery middle scraper conveyer, particularly the cable duct spillplate of non-bolt connection.
Background technology
On the slat conveyer that moves on the mechanical coal mining driving surface, be useful on the cable duct of placing cable, for preventing that coal from entering in the cable duct from adjacent two cable duct spillplates, influence the service life of cable, usually the method that adopts has two kinds, the one, at cable duct two spillplate interfaces, with the connection form of bolt lap plate; The another kind of mode that adopts adjacent spillplate tower to connect.When adopting Bolt Connection, when moving owing to slat conveyer, coal-face is uneven, is drawn bad problem with regard to spillplate often occurring; When adopting adjacent two spillplate towers to connect, prevent that for making tower from connecing part scratch cable, usually to connect part comparatively weak for tower, and intensity is low yielding, and locate bad, thereby have influence on the normal use of equipment.
Summary of the invention
The purpose of this utility model provides the cable duct spillplate that a kind of intensity is good, location failure-free non-bolt connects.
The technical solution of the utility model is: the cable duct spillplate that a kind of non-bolt connects, on slat conveyer, be fixed with the cable duct that is used to place cable, be useful on the anti-spillplate that enters cable duct to coal in cable duct one side, it is characterized in that being fixed with a lap plate in the outside of an end cable groove of every spillplate, overlapping between this lap plate and the adjacent spillplate, the lower end of lap plate is inserted between the riser and spillplate of spillplate and intermediate channel.
The fixed form of above-mentioned lap plate can adopt welding, riveted joint, bonding.
Above-mentioned lap plate is up big and down small trapezoidal.
The utlity model has simple in structurely, two spillplate towers connect that place's intensity height, location are reliable, the characteristics of long service life, are fit to the down-hole harsh environment and use.

The specific embodiment
As shown in Figure 1, the outside of one end cable groove of the every spillplate 2 of the cable duct of installing on slat conveyer 1 is welded with a lap plate 3, overlapping between this lap plate and the adjacent spillplate, the lower end of lap plate is inserted between the riser 4 of spillplate 2 and intermediate channel, and lap plate is up big and down small trapezoidal.When slat conveyer moves, because coal-face is uneven, this just makes between the adjacent spillplate and produces relative displacement, the spillplate overlapping with lap plate just can move freely, the thickness of lap plate can be identical with spillplate as required, and this has just solved because the less spillplate that causes of lap plate thickness damages.
