Abstract

The utility model discloses a central groove abrasion-resistant soleplate for a scraper conveyer. The central groove (6) consists of a M-shaped steel bar (8), a soleplate (7) and a connection bolt (9). A layer of porcelain enamel is arranged on the steel plate for the smoothness and abrasion resistance performance of the working surface; so that the movement friction factor becomes smaller and the service life of the soleplate is prolonged to effectively protect drive machines.

Description

The wear-resisting base plate of the intermediate channel of slat conveyer

Affiliated field

The utility model relates generally to a kind of mining machinery, particularly a kind of slat conveyer that is used for the conveying solid substance granule materials.

Background technology

Slat conveyer is a kind of in diggings such as metallic ore, colliery, nonmetalliferous ore, sandstones, and the load transfer device of material transportation is carried out in the washing place.By motor, hydraulic coupler, speed-changing mechanism, the sprocket chain strip transmission mechanism, scraper component, parts such as intermediate channel are formed, the power of motor moves through the scraper plate that drives on the chain behind the speed-changing mechanism, and the material on the intermediate channel is moved to the other end from an end, realizes the conveying of solid particle material.

Intermediate channel is mainly by M shaped steel, base plate, and coupling bar is formed, and works to accept, hold material, and scraper plate is close to the intermediate channel base plate, and is mobile under the drive of chain.Base plate is a fuel plate, is generally polylith and is spliced into a load-transfer device.Base plate generally adopts low-alloy steel, as 16Mn, and charcoal steel etc., wear no resistance, form, so contact with steel for steel between scraper plate and the base plate because scraper plate also is steel, friction coefficient is bigger, friction drag is big, and consumption of power is big, and base plate very easily weares and teares, the steel base plate of prior art generally only has the service life of some months, since in the down-hole or other camp sites change the cost height of base plates, also bring corresponding economic loss, expect so the technological improvement of base plate is the user.

Technology contents

The purpose of this utility model is to provide a kind of shortcoming that can overcome known technology, and wear-resisting have less mobile friction coefficient, and have than the wear-resisting base plate of the The middle pan of scraper conveyor of long life.

For achieving the above object, scheme of the present utility model is: on the driving surface of steel substrate in conjunction with one deck enamel layer.

Adopt such scheme, on the steel substrate of known technology, be coated with the last layer wearing layer, have less mobile friction coefficient between this wearing layer and the steel, moving resistance between base plate and the scraper plate reduces, wearing and tearing also reduce, thereby have prolonged the service life of base plate, have realized the purpose of this utility model.

Below in conjunction with diagram and embodiment scheme of the present utility model is described in more detail.

Fig. 2 is a slat conveyer birds-eye view shown in Figure 1;

Fig. 3 is the A-A cutaway view among Fig. 2, the i.e. constructional drawing of intermediate channel;

The specific embodiment

Slat conveyer as shown in Figures 1 and 2, by electrical motor 1, hydraulic coupler 2, change speed gear box 3, sprocket wheel chain gearing 4, scraper component 5, intermediate channel 6 parts such as grade are formed a long load-transfer device, particulate matter is placed on the base plate 7 of intermediate channel 6, and scraper plate moves under the drive of sprocket wheel chain gearing 4, thereby particulate matters such as ore, coal are promoted to finish conveying.Said apparatus generally uses in the mine etc. to be located.

Fig. 3 is the constructional drawing that the intermediate channel 6 of the involved base plate 7 of this programme is installed, and intermediate channel 6 is by M shaped steel 8, and base plate 7 and coupling bar 9 are formed, and this constructional drawing is mainly the structure of performance intermediate channel 6, thus omitted scraper plate, and drive the structures such as chain of scraper plate.In diagram, M shaped steel 8 is arranged on the support that both sides form load-transfer device symmetrically, connects two M shaped steel 8 by coupling bar 9, normally coupling bar directly is welded on the M shaped steel, and base plate 7 usefulness Connection Elements are fixed on the coupling bar 9.

Fig. 4 is the constructional drawing of base plate 7 related in the scheme, and base plate 7 is a rectangle steel flat board, is combined with one deck enamel 10 on the driving surface, be distributed on the surface of steel plate, on steel plate, two kinds of schemes are arranged in conjunction with enamel, the one, directly the middle part trough floor is carried out enamel, then with M shaped steel 8, coupling bar 9 is connected, another kind of scheme is that the middle part trough floor is not carried out enamel, makes the enamel wear plate separately, then with enamel wear plate and M shaped steel 8, base plate 7, coupling bar 9 is connected.Adopt which kind of scheme and field condition that relation is arranged, conveniently be as the criterion to use.

When adopting second kind of scheme, consider the enamel wear plate that makes separately and the connection mode of intermediate channel base plate 7, Fig. 5 is one of connection mode, the both sides of enamel wear plate 11 uniform porose 12, Kong Yuyi section short tube 13 cooperates, and uses welding or makes short tube 13 and plate 11 affixed with flush fit, when being installed to intermediate channel, short tube 13 is cooperated with pin on the base plate, and it is all very convenient that demolition is installed like this.

The connection mode of certain wear-resisting enamel plate and base plate is a lot, as bolted connection etc., but all within the imagination of present patent application, is protected equally, and this is understandable.

By such scheme design no matter be the base plate enameling or wear-resisting enamel plate is installed on base plate has all been produced good effect in actual use, have following characteristics: a at least, improved the degree of finish of driving surface, steel driving surface roughness in the past is generally 12.5-25, and the roughness of ceramic glaze surface driving surface is below 0.2; B, coefficient of sliding resistance are low, and steel-steel friction coefficient is 0.1-0.15, and enamel-steel friction coefficient is 0.02-0.03, because coefficient of sliding resistance is low, resistance of motion reduces, and the slat conveyer consumption of power is reduced, and the element of transferring power improves service life; C, because the surface abrasion resistance of enamel face is good, thereby improve greatly the service life of intermediate channel, as need only change plate when adopting scheme, the maintenance of the wear-resisting enamel plate of independent making and get final product, needn't change the whole middle groove, good and economic is arranged.
