Abstract
The utility model relates to a kind of one-sided fully opened type intermediate section groove for opening clearstory.Comprise cell body, baffle plate side channel side (3) and shovel board side channel side (1), in this cell body, plate has breach, be characterized in: on baffle plate side channel side (3), be provided with the elongated hole opened, and spacing seam is provided with on shovel board side channel side (1), also comprise plate (2), this plate (2) stretches to the indentation, there of described middle plate from the elongated hole of baffle plate side channel side (3), one end of its dagger plate (2) and baffle plate side channel help (3) to be removably connected by fastener, and its other end and shovel board side channel help the spacing seam of (1) to overlap.After adopting one-sided fully opened type intermediate section groove for opening clearstory of the present utility model, simplify existing fully opened type intermediate section groove for opening clearstory structure, solve the problem easily occurring crackle or fracture that it exists, substantially increase bulk strength and the service life of intermediate section groove for opening clearstory.
Description
Technical field
The utility model relates to a kind of one-sided fully opened type intermediate section groove for opening clearstory.
Background technology
Coal mining slat conveyer intermediate section groove for opening clearstory is the requisite component part of slat conveyer, usually the intermediate channel at interval of specified quantity arranges a joint intermediate section groove for opening clearstory, when at the bottom of slat conveyer, chain breaks down, just plate can be extracted out, be used for carrying out the maintenance such as maintenance, replacing of scraper plate, chain and chain ring.
At present, traditional fully opened type intermediate section groove for opening clearstory cell body both sides are equipped with the elongated hole opened, plate all can insert from both sides, but because cell body baffle plate side is as the passing fulcrum of support, and shovel board side is as the orbit of coalcutter, be subject to very large application force in use procedure, very easily cause stress raisers at the position offering elongated hole, cause elongated hole position to occur that crackle even ruptures.
Utility model content
The purpose of this utility model is to provide a kind of one-sided fully opened type intermediate section groove for opening clearstory, can simplify existing fully opened type intermediate section groove for opening clearstory structure, improve bulk strength and the service life of intermediate section groove for opening clearstory.
A kind of one-sided fully opened type intermediate section groove for opening clearstory, comprise cell body, baffle plate side channel side and shovel board side channel side, in this cell body, plate has breach, its special feature is: help the elongated hole being provided with and opening at baffle plate side channel, and help at shovel board side channel and be provided with spacing seam, also comprise plate, this plate stretches to the indentation, there of described middle plate from the elongated hole that baffle plate side channel is helped, one end of its dagger plate and baffle plate side channel are helped to be removably connected by fastener, and the spacing seam that its other end and shovel board side channel are helped overlaps.
The shape of its dagger plate is rectangle or parallelogram.
After adopting one-sided fully opened type intermediate section groove for opening clearstory of the present utility model, simplify existing fully opened type intermediate section groove for opening clearstory structure, solve the problem easily occurring crackle or fracture that it exists, substantially increase bulk strength and the service life of intermediate section groove for opening clearstory.Its advantage simplifies the cell body shovel board side locate mode that puts in a skylight, and adopts overlap joint seam spacing, reduces the defect point easily producing stress and concentrate, improve fully opened type intermediate section groove for opening clearstory bulk strength, thus increase its service life.

Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the N direction view of Fig. 1;
Accompanying drawing 3 is the A-A cutaway view of Fig. 1.
Detailed description of the invention
As Fig. 1, 2, shown in 3, the utility model provides a kind of one-sided fully opened type intermediate section groove for opening clearstory, comprise cell body, baffle plate side channel side 3 and shovel board side channel side 1, in this cell body, plate has breach, baffle plate side channel side 3 is provided with the elongated hole opened, and spacing seam is provided with in shovel board side channel side 1, also comprise plate 2, this plate 2 stretches to the indentation, there of described middle plate from the elongated hole of baffle plate side channel side 3, one end of its dagger plate 2 and baffle plate side channel help 3 to be removably connected by fastener (such as bolt), and its other end and shovel board side channel help the spacing seam of 1 to overlap together with (such as passing through male-female engagement).The shape of its dagger plate 2 is rectangle or parallelogram.Through probationary certificate, parallelogram is adopted to be conducive to improving intermediate section groove for opening clearstory bulk strength further.
Claims (2)
1. an one-sided fully opened type intermediate section groove for opening clearstory, comprise cell body, baffle plate side channel side (3) and shovel board side channel side (1), in this cell body, plate has breach, it is characterized in that: on baffle plate side channel side (3), be provided with the elongated hole opened, and spacing seam is provided with on shovel board side channel side (1), also comprise plate (2), this plate (2) stretches to the indentation, there of described middle plate from the elongated hole of baffle plate side channel side (3), one end of its dagger plate (2) and baffle plate side channel help (3) to be removably connected by fastener, and its other end and shovel board side channel help the spacing seam of (1) to overlap.
