Abstract
The utility model discloses a long chain conveying system scraper blade holder is a novel a scraper blade holder that is used for limit double-chain conveyor long chain conveying system, and specifically speaking is a scraper blade chain annex of limit double-chain conveyor for the chain and the scraper blade of conveyer scraper blade chain system are connected. The utility model discloses compare with current ordinary list, diplopore open type go-between and join in marriage short chain scraper blade chain system structure, be applicable to long chain and seal ring chain conveying system, the rotatable arbitrary flat ring of packing into long chain of scraper blade holder under the dismouting chain and chain are in the tensioning state, can adjust the scraper blade position at will or increase and decrease scraper blade quantity, easy operation is swift.
Description
Technical Field
The utility model relates to the technical field of a long chain conveying system of a side double-chain conveyor, which is applied to the assembly of a chain and a scraper of the side double-chain conveyor; is a replacement product of the scraper chain of the existing side double-chain conveyor (such as a slag extractor of a power plant, a cast stone scraper, and the like). In particular to a scraper chain conveying system connected with a long chain and a scraper holder, which replaces a scraper chain conveying system combined with a short chain and an open connecting ring, and can be widely applied to slag extractors, cast stone scraper machines and the like of power plants, building materials and mines.
Background
In the prior art, a scraper chain system of a ring chain conveyor (such as a slag extractor of a power plant, a cast stone scraper and the like) is mainly formed by combining short chains and an open type connecting ring, and the specific structure is that the two short chains are connected by the open type connecting ring, and then the open type connecting ring is connected to a scraper by bolts. The open type connecting ring bears the power transmitted in the chain transmission process and the resistance of the scraper in the operation process in the use process, and the open type connecting ring is an open structure connected by bolts, so that the whole fatigue life of the scraper chain system is reduced, and the open type connecting ring is a weak link of the scraper chain system; the operation is complicated when changing the chain and the scraper simultaneously, and the assembly and the disassembly can not be carried out under the condition of tensioning the chain.
For overcoming the deficiencies of the prior art, the utility model provides a novel long chain movably connected scraper blade holder, this scraper blade holder has improved the whole fatigue life of scraper chain system, satisfies the user equipment and the requirement of decomposing of scraper blade under the chain tensioning condition simultaneously.
Disclosure of Invention
The utility model aims at: the optimized substitute product of the short chain and opening connecting ring combined scraper chain conveying system is provided, the overall fatigue life of the scraper chain system is prolonged, and the quantity of the scrapers or the broken scrapers can be conveniently and rapidly increased or decreased under the tensioning state of the chain when the conveying capacity of the scraper chain machine is changed or the chain breaks down.
The utility model adopts the technical proposal that: the scraper chain system of the scraper holder of the novel long chain conveying system mainly comprises a scraper holder 1, a locking nut 2 and a bolt 3; the scraper holders 1 are vertically intersected with the central line of the long chain I, the two scraper holders 1 are symmetrically used, one of the two scraper holders is placed in a long circular hole in the middle of the chain I in a connected mode through rotation, and the other scraper holder is placed in a long circular hole in the middle of the same chain I in the opposite direction through rotation. The two movably connected clamps clamp the scraper in the middle through bolts and nuts.
The utility model has the advantages that: the utility model discloses can assemble and decompose under the condition of tensioning chain again, shorten the equipment cycle of scraping the chain system, reduce user's cost. The utility model discloses a scrape trigger chain system scraper blade holder and only receive the power of the scraper blade of connecting, the tension in the transmission process has chain itself to undertake, has improved the atress condition of connecting piece, compares with the scraper blade chain of open type connection annular form and has improved the whole fatigue life of scraper blade chain greatly, has reduced the cost that the user changed.
Description of the drawings:
FIG. 1 is an assembly view of the scraper holder of the long chain conveying system of the present invention;
FIG. 2 is an exploded view of the scraper blade holder of the long chain conveyor system of the present invention;
FIG. 3 is a front view of the scraper holder of the long chain conveying system of the present invention;
FIG. 4 is a top view of the scraper blade holder of the long chain conveying system of the present invention;
in the figure: the scraper chain mechanism comprises a scraper plate holder 1, a locking nut 2, a bolt 3, a long chain, a scraper plate, a chain ring straight arm I, a chain ring straight arm II, a chain clamping groove I, a chain clamping groove II, a scraper plate contact surface I and a scraper plate contact surface II;
the specific implementation mode is as follows:
the utility model provides a low trouble, high reliability, the simple scraper blade holder of maintenance suitable for limit double-chain conveyor long chain conveying system mainly comprises scraper blade holder 1, lock nut 2, bolt 3. The specific implementation scheme is that one chain clamping groove II of two scraper clamps 1 is opened and downwards rotated to be arranged in a long chain long round hole, a chain ring straight arm I of the long chain is ensured to be clamped in the chain clamping groove I of the scraper clamp 1, a chain ring straight arm II of a long chain is clamped in the chain clamping groove II of the scraper clamp 1, the other scraper clamp 1 is opened and upwards rotated to be arranged in the same long round hole of the long chain, and the assembly form is the same as the above; the scraper contact surfaces I (c) of the two scraper holders (1) are respectively tightly attached to the scraper contact surfaces II (b) on the two sides of the scraper (c) and are screwed and fixed by bolts (3) and locking nuts (2). The illustration and description is in the form of a single strand with double strands at one end and identical strands at the other end.
Claims (2)
1. Novel long chain conveying system scraper blade holder, characterized by: mainly comprises a scraper holder (1), a locking nut (2) and a bolt (3); the scraper holder (1) is a double-chain-clamping-groove straight-handle connecting structure, the front part is provided with two U-shaped grooves, namely a horizontally-opened chain clamping groove I and a vertically-opened chain clamping groove II, and the arc and the width of the U-shaped grooves are equal to the diameter d +1mm of a straight arm of a chain ring; the rear part is a straight handle with double round holes.
