Abstract
The utility model provides a fork-shaped buried scraper conveying chain which is composed of at least two chain links. The chain links are in head-tail connection through pins. Each pin is provided with a gasket for locking and a cotter pin. Each chain link comprises a chain rod and a scraper plate. Two ends of the chain rod are respectively provided with a flat cylindrical joint and a fork-shaped cylindrical joint. Two scraper plates which are in symmetry in a left-and-right direction are vertically welded on two external side walls of the fork-shaped cylindrical joint. The heights of the chain rod and each scraper plate are 47-49mm. The thickness of each scraper plate is 8.5-9.5mm. Each scraper plate is provided with a reinforcing rib. Each reinforcing rib is in welding connection with the external wall of the fork-shaped cylindrical joint. The radius of the external arc on the flat cylindrical joint and the fork-shaped cylindrical joint is 23.5-24.5mm. The flat cylindrical joint and the fork-shaped cylindrical joint are respectively provided with a pin hole which is matched with the pin. The diameter of the pin is 20-22mm. The fork-shaped buried scraper conveying chain has the following advantages: improving impact load resistance, and improving wearing resistance and tensile strength of the scraper conveying chain because the diameter of the pin is enlarged.
Description
Technical field
The utility model relates to a kind of conveyer chain, and particularly a kind of fork-shaped be used to burying on the sweep-out mechanism buries paddled conveyor chain.
Background technology
Burying paddled conveyor chain is the main working parts of embedded scraper transporter.It is comprised of chain and scraper plate two parts.During convey materials, moving chain and scraper plate are done as a whole, are embedded in to be transferred among the material in the housing of sealing, drive material movement and do not finish transportation work.The fork-shaped scraper chain is the special chain of embedded scraper transporter.The chain of its structure and other kind differs greatly.It has the characteristics such as simple in structure, easily manufactured obdurability is good and is applicable to the heavier long distance conveying of load, therefore the fork-shaped scraper chain is widely used in low speed, heavy duty, has and impact transmission, and the more abominable occasion of working environment, such as steel mill's dedusting, the occasions such as Exploit sand and stone, coal exploitation processing.But existing fork-shaped buries paddled conveyor chain in the situation of long-term use or heavy duty, scraper plate and chain bar produce flexural deformation easily, has undercapacity, the defectives such as poor durability, and because the diameter of bearing pin is less, cause easily wearing and tearing, make whole chain the phenomenon of snakelike unstability in the process of work, occur, cause potential safety hazard.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of intensity high, and not yielding, the anti abrasive fork-shaped of bearing pin buries flight chain.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of fork-shaped buries paddled conveyor chain, formed by at least two chain links, end to end by bearing pin between each chain link, be provided with pad and the spring cotter of locking usefulness on the bearing pin, chain link includes chain bar and scraper plate, the two ends of described chain bar are respectively arranged with flat column joint and fork-shaped column joint, vertical welding is followed two left sides on two lateral walls of fork-shaped column joint, the scraper plate of right symmetry, the height of chain bar and scraper plate is 47-49mm, the thickness of scraper plate is 8.5-9.5mm, be provided with reinforced rib on the described scraper plate, the lateral wall of reinforced rib and fork-shaped column joint is welded to connect, the radius of the external arc on flat column joint and the fork-shaped column joint is 23.5-24.5mm, all offers the pin shaft hole supporting with bearing pin on flat column joint and the fork-shaped column joint, and the diameter of bearing pin is 20-22mm.
The length of scraper plate is 120mm, and the length of reinforced rib is 90mm.The thickness of described scraper plate is 9mm.
The radius of the external arc on described flat column joint and the fork-shaped column joint is 24mm.
The diameter of described bearing pin is 21mm, and the diameter of pin shaft hole is 21.13mm.
The beneficial effect that the utility model compared with prior art has is: the fork-shaped that the utility model provides buries paddled conveyor chain and is formed with the scraper plate seam by the chain bar and link, and forms the fork-shaped flight chain with bearing pin, packing ring, the locking of spring cotter serial connection.Because the scraper thickness of scraper chain increases, and carried out beading technique on the scraper plate, the radius of the external arc of flat column joint and fork-shaped column joint increases, tensile strength, fastness and the anti-torque of chain have greatly been improved, improved the impact load ability that fork-shaped buries paddled conveyor chain, and because the diameter overstriking of bearing pin has improved scraper chain resistance to abrasion and resistance to tension in use, avoided in the course of the work, the phenomenon of snakelike unstability occurred.
