Abstract
A middle groove of scraper conveyor is provided with upper and lower chain channel grooves and groove side plates at two sides, wherein a middle plate is disposed between the upper and lower chain channel grooves; the groove side plate at one side is provided with and connected to a shovel plate, and the groove side plate at the other side is provided with a crect ear connected to a thrust oil cylinder; dumbbell pin slots are disposed at two ends of the groove side plates; the bottom of the shovel plate is provided with a plurality of closed vibration-isolating slots; a plurality of vertical studs are disposed between the dumbbell pin slots and the crect ear; the external baffle of the dumbbell pin slot is integrally connected to the stud adjacent to the dumbbell pin slot. A drawing type movable overhaul plate is disposed on the middle plate for connecting the external baffle of the dumbbell pin slot and the lower part of the studs, so that the overall stress intensity is greatly improved without increasing materials. The vibration-isolating slots designed under the dumbbell pin slot are in closed structures; the bearing capacity of the closed structures is far greater than the bearing capacity of opening structures; simultaneously the casting materials are reduced. An opening space is reserved for the opening slot with the same specification.
Description
Technical field
The utility model 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 problems to be solved in the utility model 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 problems to be solved in the utility model 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 problems to be solved in the utility model 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 utility model 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. 1 is a structure diagram of the present utility model.
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.
