Abstract

Disclosed is a novel scraper chain conveyor, which comprises a frame, a drive chain and a slave chain arranged on the two ends of the frame, a scraper chain circled around the frame. A tighten device is also arranged on the end of slave chain of the frame. The improvement of the utility model lies in: a. An outer alloy sleeve is arranged on the axle hole of the scraper chain in the scraper chain device, an inner alloy sleeve is fixed on the pin axle; b. A tightening spring is provided with the rear of the adjustable screw on the tightening device; The utility model solves the problem of frequent adjustment and replacement of the connection pin axle due to quick abrasion, and emendation of the tightening device existed in the original scraper conveyor. The utility model is extensively applied in metallurgy, coal, chemistry, power and architecture etc industry, which is ideal device for conveying material at palletizing plant and steel plant in the steel industry.

Description

Novel apron conveyer

(1) technical field: the utility model relates to load transfer device, is a kind of later-model apron conveyer.

(2) background technology: apron conveyer is a renewal product of introducing advanced foreign technology, be widely used in metallurgy, coal, chemical industry, electric power, industries such as building materials, especially the pelletizing plant in steel industry, steelworks is used for carrying the optimal equipment of grog, its structure mainly includes: frame, be contained in the drive sprocket and the driven sprocket at frame two ends, around the carrier bar messenger chain on the frame, this messenger chain includes the more piece chain bucket, carrier bar is equipped with in each chain bucket both sides, adopt bearing pin to be connected between carrier bar and the carrier bar, end at the frame flower wheel also is equipped with take-up device, this take-up device includes the seat that loads that a driven sprocket connects one, be connected with the adjusting screw mandrel with loading seat, the adjusting screw mandrel is loaded on the frame to be strained.In application, we find that there are two big shortcomings in this apron conveyer: 1. carrier bar does not have axle sleeve with the bearing pin that is connected between the carrier bar, and quick abrasion needs often replacing; 2. owing to the vibration in mechanical wear and the work, the take-up device of its driven sprocket end is loosening easily, needs often to proofread and correct.

(3) summary of the invention: the purpose of this utility model will overcome in the prior art exactly, the bearing pin quick abrasion, and take-up device needs frequent calibration problem, and a kind of novel apron conveyer is provided.

Concrete scheme of the present utility model is the improvement to existing apron conveyer, it has the basic structure of existing apron conveyer, mainly include frame, be contained in the drive sprocket and the driven sprocket at frame two ends, around the carrier bar messenger chain on the frame, this messenger chain includes the more piece chain bucket, carrier bar is equipped with in each chain bucket both sides, adopt bearing pin to be connected between carrier bar and the carrier bar, end at the frame flower wheel also is equipped with take-up device, this take-up device includes the seat that loads that a driven sprocket connects one, be connected with the adjusting screw mandrel with loading seat, the adjusting screw mandrel is loaded on the frame to be strained, and its improvement is: a. is in described carrier bar messenger chain device, outer alloy cover is housed in the axis hole on the carrier bar, and alloy cover on bearing pin, fixedly being equipped with; B. be equipped with at the adjusting screw mandrel afterbody of described take-up device and load spring.

The utility model has improved service life greatly owing to be provided with inside and outside two-layer alloy sleeve between bearing pin and carrier bar axis hole, and makes to change and make things convenient for, add in its afterbody take-up device load spring after, load automatically, reduced labor strength.

(4) description of drawings:

Fig. 1 is an overall structure scheme drawing of the present utility model;

Fig. 2 is the utility model chain bucket, carrier bar connection diagram;

Fig. 3 is the scheme drawing of the utility model take-up device part.

Among the figure: 1-driven sprocket, 2-take-up device, 3-carrier bar messenger chain, the 4-frame, 5-drive sprocket, 6-chain bucket, the 7-carrier bar, alloy cover in the 8-bearing pin, 9-, the outer alloy cover of 10-, the 11-connecting panel, 12-loads seat, the 13-nut, 14-regulates screw mandrel, 15-spring perch, 16-loads spring, 17-lower shaft hole, 18-upper shaft hole.

(5) specific embodiment:

Referring to Fig. 1, the utlity model has steel frame 4, head end in frame 4 is equipped with drive sprocket 5 (external driver train), tail end is equipped with driven sprocket 1, around frame 1 carrier bar messenger chain 3 is installed, this messenger chain 3 is to be in series by more piece chain bucket 6, referring to Fig. 2, a left side fixedly is equipped with by connecting panel 11 in the both sides of each chain bucket 6, right carrier bar 7, the two ends design of carrier bar 7 has last lower shaft hole 17,18, on between carrier bar and the carrier bar, lower shaft hole 17, adopt bearing pin 8 to connect after 18 contrapositions, alloy cover 10 outside particularly the setting-in flush fit has in the upper shaft hole 18 of carrier bar 7 in the utility model, and alloy cover 9 in flush fit is equipped with on bearing pin 8, in, between the outer alloy cover 9 and 10 is running-fit, can reduce wear, improve service life greatly.

In the utility model, be connected with driven sprocket 1 take-up device 2 is housed, its structure is referring to Fig. 3, it include one be connected one with driven sprocket 1 load seat 12, the afterbody that loads seat 12 has the screw mandrel 14 of adjusting, regulate screw mandrel 14 and be loaded on tension on the frame 4, particularly add and load spring 16, and be furnished with spring perch 15 and nut 13 at the rear of regulating screw mandrel 14.The improvement of this structure, make machinery take place wearing and tearing loosening after, realize automatically loading, reduce manual shift.

Claims

1. novel apron conveyer, mainly include frame, be contained in the drive sprocket and the driven sprocket at frame two ends, around the carrier bar messenger chain on the frame, this messenger chain includes the more piece chain bucket, carrier bar is equipped with in each chain bucket both sides, adopt bearing pin to be connected between carrier bar and the carrier bar, end at the frame flower wheel also is equipped with take-up device, and this take-up device includes the seat that loads that driven sprocket connects one, and loads seat and is connected with the adjusting screw mandrel, the adjusting screw mandrel is loaded on the frame to be strained, it is characterized in that: a. is equipped with outer alloy cover in the axis hole on the carrier bar in described carrier bar messenger chain device, and alloy cover in fixedly being equipped with on bearing pin; B. be equipped with at the adjusting screw mandrel afterbody of described take-up device and load spring.
