Abstract
The invention discloses a middle groove of a scraper conveyer. The middle groove is provided with an upper chain channel, a lower chain channel and groove ledge plates on the two sides, wherein a middle plate is arranged between the upper chain channel and the lower chain channel; the groove ledge plate on one side is connected with a shoveling plate; the groove ledge plate on the other side is provided with a vertical lug which is connected with a thrust oil cylinder; the two ends of the groove ledge plates are provided with dumbbell pin clamping grooves; the bottom of the shoveling plate is provided with a plurality of closed damping grooves; a plurality of vertical studs are arranged between the dumbbell pin clamping grooves and the vertical lug; and an outer baffle plate of a dumbbell pin clamping groove is integrally connected with a stud adjacent to the outer baffle plate. The middle plate is provided with a draw type movable overhauling plate to connect the lower part of the outer baffle plate of the dumbbell pin clamping groove with the stud, so the overall stressing strength is greatly improved on the premise of not increasing materials excessively. The damping groove arranged below the shoveling plate has a closed structure, so the bearing capacity is far more than that of an open structure, and materials used for casting are reduced simultaneously. An open space is reserved for design of an open groove of the same specification.
Description
Technical field
The present invention relates to a kind of corollary equipment of slat conveyer of coal mining high yield, particularly a kind of The middle pan of scraper conveyor.
Background technology
Present underground mechanical coal mining is equipped in the leading enterprise of world wide German DBT company, the long-armed company of the U.S. and Britain JOY company.There are Zhangjiakou coal machine factory, northwest fleeing cattle in stampede, shanxi coal machine etc. in the large-scale slat conveyer of domestic production enterprise.China Shenhua as world-class producing coal rich and influential family, the main flow equipment of its use, especially key equipment dependence on import.Along with the continuous increase that country requires coal production, group of Shenhua is also improving constantly the performance requriements of coal excavation apparatus.And the research and development progress of Foreign Company and past-sale service ability have not satisfied the Shenhua realistic situation, and the intermediate channel intensity of the enterprise of coal machine manufacturing both at home and abroad is low, load-carrying capacity is little, and consumptive material is many simultaneously.
Summary of the invention
The technical problem to be solved in the present invention is at the deficiencies in the prior art, has proposed a kind of intensity height, The middle pan of scraper conveyor that load-carrying capacity is big.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of The middle pan of scraper conveyor, be provided with, the ledge plate of following chain road groove and both sides, on, be provided with middle plate between the following chain road groove, wherein the ledge plate of a side is established and is connected with shovel board, opposite side ledge plate is provided with the crect ear that joins with push action cylinder, be provided with the dumbbell pin draw-in groove at the two ends of ledge plate, be characterized in: the bottom of described shovel board is provided with some closed damping grooves, be provided with some vertical studs between dumbbell pin draw-in groove and crect ear, the outer baffle of dumbbell pin draw-in groove and adjacent with it stud connect as one.
The technical problem to be solved in the present invention can also come further to realize by the following technical programs, has access hole on the middle plate, and access hole is provided with the movable access panel of drawing and pulling type, and access panel is set to be convenient to the trapezium structure of pull.
The present invention compared with prior art for intermediate channel two ends point of attachment rigidity strengthens, is designed to the bottom with the outer baffle and the stud of dumbbell pin draw-in groove and links to each other, and integral body is subjected to force intensity exceeding under the prerequisite that increases material, is greatly improved.Design-calculated damping groove in shovel board below is an enclosed construction, and load-carrying capacity is far longer than open architecture, has reduced the casting material simultaneously.For the under shed space is reserved in the design of same specification open slot.

Fig. 2 is the left view of Fig. 1.
Fig. 3 is the birds-eye view of Fig. 1.
Fig. 4 is that the A of Fig. 2 is to view.
The specific embodiment
A kind of The middle pan of scraper conveyor, be provided with cochain road groove 9, following chain road groove 12, the ledge plate 8 of both sides and base plate 11, on, be middle plate 10 between the following chain road groove, wherein the ledge plate of a side is established and is connected with shovel board 7, opposite side ledge plate is provided with the crect ear 6 that joins with push action cylinder, the dumbbell pin draw-in groove of using when being provided with two intermediate channel butt joints 1 at the two ends of ledge plate, the bottom of described shovel board 7 is provided with some closed damping grooves 14, be provided with some vertical studs 3 between dumbbell pin draw-in groove 1 and crect ear 6, the outer baffle 2 of dumbbell pin draw-in groove and 3 castings of adjacent with it stud connect as one.Have access hole on the middle plate, access hole is provided with the movable access panel 13 of drawing and pulling type, and access panel 13 is set to be convenient to the trapezium structure of pull.Stud over against the big end of access panel is the muscle 4 of living, and standard cell is used, and open slot removes does opening.
This new process can effectively guarantee middle plate, the base plate welding quality of intermediate channel.The routing process is as follows:
When organizing ledge plate and middle plate, positive evenly spot welding everywhere.Two ends welding lacing wire.
Whole weld preheating.
Earlier in the welding 1/2 of backboard face weld bead height, the welding of multilayer multiple tracks.
Plate front in the welding before the weldering cleans out spot weld polishing everywhere in early stage again.
The weld seam of backboard face remainder in the welding; The welding base plate.
After integral body welds, insulation annealing.
Claims (2)
1. The middle pan of scraper conveyor, be provided with the ledge plate of upper and lower chain road groove and both sides, be provided with middle plate between the upper and lower chain road groove, wherein the ledge plate of a side is established and is connected with shovel board, opposite side ledge plate is provided with the crect ear that joins with push action cylinder, be provided with the dumbbell pin draw-in groove at the two ends of ledge plate, it is characterized in that: the bottom of described shovel board is provided with some closed damping grooves, be provided with some vertical studs between dumbbell pin draw-in groove and crect ear, the outer baffle of dumbbell pin draw-in groove and adjacent with it stud connect as one.
