Abstract
A multifunctional scraper blade chain group comprises a chain rod, four segments of scraper blade chains are a group, the four segments of the scraper blade chains are sequentially connected, a T-shaped inclined scraper blade is arranged on the first segment of scraper blade chain, a saw-tooth-shaped scraper blade is arranged on the second segment of scraper blade chain, a fishbone-shaped scraper blade is arranged on the third segment of scraper blade chain, and a square scraper blade is arranged on the fourth segment of scraper blade chain. The scraper blade chains are good in comprehensive mechanical properties, high in strength, and abrasion-resistant. The multifunctional scraper blade chain group effectively solves the problems of chain floating and blocking when the scraper blade chains are used for a burying scraper blade coal feeder.
Description
Technical field
A kind of multifunctional scraper chain of the utility model group is used for burying the scraper plate feeder.
Background technology
Flight chain is the core component of embedded scraper transporter, and flight chain must have high intensity, light quality, good resistance to abrasion, good interchangeability.And the at present domestic heat-resistant antifriction foundry goods that adopts is made the chain bar more, as ZG40Cr9Si2, and tensile strength sigma b＜600Mpa, rupture strength can only reach with the intensity of cross section dropforged chain half, under the same strength condition, weight doubles, and wear ability has just descended more than one times.Casting Parts is easy to generate inner mass defect simultaneously, and chain rupture in might using brings potential faults to the end user.
In addition, because the high humidity of coal, coal easily is bonded at the bottom of burying the scraper plate feeder, and flight chain is in operation and easily floats chain.Star feeder sticks coal, has become a cylinder after the long-time running, causes passage to stop up; The star feeder blade is often blocked by foreign matter and causes chain rupture, often scurries into duff in the star feeder axle sleeve, causes frictional heating and burns out.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of multifunctional scraper chain group, and comprehensive mechanical performance is good, intensity is high, wear-resistant.Effectively solve flight chain for floating chain, the blockage problem of burying the scraper plate feeder.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of multifunctional scraper chain group, comprise the chain bar, described flight chain four joints are one group, four joint flight chains connect successively, the first segment flight chain is provided with T type inclination scraper plate, the second joint flight chain is provided with the serration scraper plate, and the 3rd joint flight chain is provided with the herringbone scraper plate, and the 4th joint flight chain is provided with square scraper plate.
Described T type inclination scraper plate tilts to be connected with the vertical direction of chain club body; Described herringbone scraper plate tilts to be connected with the vertical direction of chain club body.
The vertical direction of described T type inclination scraper plate and chain club body is 45 ° of inclination angle welding; The vertical direction of described herringbone scraper plate and chain club body is 5 ° of inclination angle welding; Described T type inclination scraper plate bottom is provided with the cutting edge at 15 ° of inclination angles.
Described chain bar comprises dropforged chain, which is provided with bearing pin, and described dropforged chain, bearing pin are the 40Cr material.
Described bearing pin and chain bar are locked by collar, and collar is the face contact with contacting of bearing pin.
Described four joint scraper plates are the 16Mn material.
A kind of multifunctional scraper chain of the utility model group, the flight chain design is one group with four joints, this four joints flight chain is except the function with convey materials, have the unique function of oneself separately in addition: first segment is T type inclination scraper plate, scraper plate becomes 15 ° of inclination angle welding with chain shaft vertical direction, allow chain produce downward component to overcome the buoyancy of flight chain when operation drives material, the cutting edge shape at 15 ° of inclination angles is processed in the scraper plate bottom, effectively removes the bottom buildup.
Second joint is the sawtooth pattern scraper plate, and this scraper plate can prevent the coal seam compacting, effectively removes the bottom buildup.
The 3rd joint is for the perverse shape scraper plate of fish, and scraper plate and chain bar soldering angle change and vertically be welded as 5 °, and welding namely is the perverse shape of fish, and it is stressed to reduce scraper plate, but flight chain automatic centering simultaneously prevents that the wiping of sideslip and housing from bumping.
The 4th joint is the square scraper plate, and this scraper plate has the function of broken arch, prevents the coal seam arch camber, satisfies the operational throughput requirement.

The specific embodiment
As Fig. 1 ~ shown in Figure 6, a kind of multifunctional scraper chain group, comprise chain bar 1, described flight chain four joints are one group, four joint flight chains connect successively, and the first segment flight chain is provided with T type inclination scraper plate 2, the second joint flight chains and is provided with serration scraper plate 3, the 3rd joint flight chain is provided with herringbone scraper plate 4, the four joint flight chains and is provided with square scraper plate 5.
Described T type inclination scraper plate 2 is 45 ° of inclination angle welding with the vertical direction of chain bar 1 shaft.Described herringbone scraper plate 4 is 5 ° of inclination angle welding with the vertical direction of chain bar 1 shaft.Described T type inclination scraper plate 2 bottoms are provided with the cutting edge at 15 ° of inclination angles.
Described chain bar 1 comprises: dropforged chain, which is provided with bearing pin 6, and described dropforged chain, bearing pin 6 are the 40Cr material.Described four joint scraper plates are the 16Mn material.Bearing pin 6 adopts collar 7 lockings with chain bar 1, and collar 7 is the face contact with contacting of bearing pin 6, has guaranteed the reliability of chain.
Chain bar 1 adopts the high strength dropforged chain, and dropforged chain and bearing pin material are 40Cr, carries out superficial cementation and handles, and hardness is HRC52～62; This material is a kind of low-carbon alloy steel, heatproof, wear-resisting not only, and in light weight, intensity is high.Scraper plate is selected 16Mn for use, is not less than service life 20000 hours.
