Abstract
A middle trough for a conveyor consists of a ledge, a middle plate and other parts, and a layer of wear-resistant alloy is spray-welded at the end of the ledge by using a plasma spray welding technology. The length of the spray welding layer is 5-8 cm, and the width of the spray welding layer is 2-4 cm. The thickness of the material is 0.1-0.2 cm. The sprayed layer is flat and smooth, the process is simple, the wear resistance of the sprayed ledge end is more than two times higher than that of the ledge end which is made of the same material and is subjected to intermediate frequency quenching, and the increased cost only occupies about 10 percent of the high manganese steel end. The service life of the conveyor is obviously prolonged, and remarkable social and economic benefits are obtained.
Description
The utility model belongs to a kind of parts of mine flight conveyer.
Intermediate channel is the critical component of mine flight conveyer acknowledgement of consignment coal, is to be formed by ledge, middle plate and other part assembly weldings.Because its underground work environment is abominable, in the laying docking site, intermediate channel two ends exist upper and lower, left and right buckling phenomenon, be in operation, scraper chain will produce bigger normal load to the intermediate channel end of bending, thereby accelerate the wearing and tearing of intermediate channel end, cause that intermediate channel lost efficacy.The intermediate channel end wear lost efficacy and accounted for more than 80% of intermediate channel inefficacy at present, and the wearing and tearing of ledge termination and middle front edge of board and scraper plate friction place are its principal mode.Relevant both at home and abroad producer has partly adopted wear-resisting measure preferably in the chain road of centering plate, thereby makes the wear-resisting key factor that influences the intermediate channel life-span that becomes of ledge termination.Have for improving the method that adopts in ledge wear resisting property and service life: one, change the material of ledge, improve its intensity and resistance to abrasion, but need the exploitation new steel grade, cost improves by a relatively large margin; Two, add the ledge termination that one section shape of weldering high manganese steel same with it is made in the ledge end, but welding technique, welding material and quality of workers are all had higher requirements; Three, carry out mid frequency induction hardening at ledge two ends regional area, but can not guarantee in qualitative conformability, wear resisting property can not reach designing requirement fully.Above-mentioned measure raising in various degree the resistance to abrasion of ledge, also exist significantly not enough.
The purpose of this utility model is exactly in order to overcome above-mentioned deficiency, with under the prerequisite of common iron, to increase the rub proofness that less one-tenth improved ledge originally significantly, reaches the prolongation intermediate channel purpose in service life.
The technical solution adopted in the utility model is: front edge of board plasma spray welding technology surfacing one deck abrasion resistant alloy in the place easy to wear, upper and lower leg chain road, intermediate channel ledge two ends that makes of common iron reaches.About 10～30 sq cms of its area, about 0.1～0.2 centimetre of thickness.Sprayed coating is smooth smooth, its area and thickness also are easy to control, manufacturability welding or mid frequency induction hardening is simple, through the resistance to abrasion of the ledge termination that spray treatment is crossed than identical material through will the exceeding more than two times of mid frequency induction hardening, and the cost that is increased only takies about 10% of high manganese steel termination.
Come the utility model is described below in conjunction with accompanying drawing.
Fig. 1 is the intermediate channel front view, and (1) is left ledge, and (2) are middle plates, and (3) are right ledges, and (4), (5), (6), (7) are middle front edge of board surfacing abrasion resistant alloy places.(8), (10) and (9), (11) are respectively surfacing abrasion resistant alloy places, left and right ledge end, A-B is the cochain road, C-D is chain road down.
Fig. 2 is the intermediate channel right elevation, and (3) are right ledges, and (9), (11) and (12), (13) are respectively the abrasion resistant alloy places of the forward and backward two ends of right ledge through plasma spray.
Fig. 3 is Fig. 2 left end birds-eye view.(4), (5), (6), (7) are middle front edge of board surfacing abrasion resistant alloy places among the figure, and its rear end does not have the surfacing place.
In Fig. 1: each termination of left and right ledge end has had 8 local one deck abrasion resistant alloys that adopted plasma spray welding technology surfacings, as shown in Figure 2.In Fig. 2, can see the abrasion resistant alloy place of 4 surfacings on the right ledge (3), in fact left ledge (1) and right ledge (3) at cooresponding position 4 surfacings are arranged also in the same way the abrasion resistant alloy place.As shown in Figure 3: the front end of middle plate has had 4 local surfacings one deck abrasion resistant alloy.The rear end of middle plate is not carried out surfacing and is handled.Before surfacing, do not need the surfacing place is carried out special processing.All spray-welding coatings can be oblong, and all a represent the length of spray-welding coating among the figure, and between 5～8 centimetres, b then represents its width, between 2～4 centimetres.Its thickness is between 0.1～0.2 centimetre.Need not carry out any heat treatment behind the surfacing.Spray material adopts the iron based alloy powder: the material model is wherein any such as WF372, WF374, WF371, FE8001, FE-11, F314.Experimental results show that its effect has reached the purpose of our invention fully.
The utility model technology is simple, and quality is easy to control, and sprayed coating is smooth smooth, has improved the wear resisting property energy of ledge widely, in the service life of significantly having improved conveyer, has obtained the significant social economic benefit.
Claims (2)
1, the intermediate channel with wear-resisting ledge termination is formed by ledge, middle plate and other part assembly weldings, it is characterized in that: at ledge termination surfacing one deck abrasion resistant alloy.
2, the described conveyer intermediate channel of claim 1, the length that it is characterized in that spray-welding coating is between 5～8 centimetres, and its width is between 2～4 centimetres, and its thickness is between 0.1～0.2 centimetre.
