Abstract
The utility model provides a scraper conveyor chain clamping device has solved the scraper conveyor chain clamping device among the prior art and has been unfavorable for chain connection construction, the great technical problem of risk ratio. The steel plate comprises a steel plate (1) and a horseshoe ring (2), wherein the upper part of the horseshoe ring (2) is connected to two ends of the steel plate (1), and a through hole (3) is formed in the lower part of the horseshoe ring (2); the gap at the lower part of the horseshoe ring (2) is larger than the chain diameter of the chain; the size of the through hole (3) is smaller than the inner width of the chain; the length of the steel plate (1) is matched with the width of the scraper conveyor. The chain is clamped and fixed by the horseshoe rings (2) at the two ends, so that the risks of chain dropping, chain breaking, finger clamping and the like when the scraper chain is connected are reduced, and the safety accident risk rate of field workers is reduced; and has small volume, light weight and simple operation.
Description
Technical Field
The utility model relates to a scraper conveyor, concretely relates to scraper conveyor chain clamping device.
Background
A scraper conveyor, which is a conveyor for conveying bulk materials in a tank by utilizing the traction of a scraper chain; in the current coal mining working face, the scraper conveyor not only is used for conveying coal and materials, but also is used as a running track of a coal mining machine, so that the scraper conveyor becomes indispensable main equipment in a modern coal mining process, and production can be normally carried out as long as the scraper conveyor can keep continuous running; otherwise, the whole coal face will be in a production stop state, so that the whole production is interrupted.
Like the multi-chain scraper conveyor and scraper conveyor scraper chain of application number CN201620393382.3, including the scraper blade to and the chain that is connected with the scraper blade, its characterized in that: the chain is at least including two endless chain chains, the tip of scraper blade passes through scraper chain connecting piece joint on the chain, is equipped with side direction draw-in groove and vertical draw-in groove on this scraper chain connecting piece, and the side direction draw-in groove and the vertical draw-in groove joint of same scraper chain connecting piece are in same chain link of chain.
When the scraper conveyor is extended, a chain type chain clamping device is needed to be connected with a chain of the scraper conveyor; however, when the chain clamping device is used, risks such as chain dropping, chain breaking and finger clamping are easy to occur, and the risk rate of safety accidents of field construction personnel is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a scraper conveyor chain clamping device to the scraper conveyor chain clamping device who solves among the prior art is unfavorable for the chain to be connected construction, the great technical problem of risk ratio. The utility model provides a plurality of technical effects that preferred technical scheme among a great deal of technical scheme can produce see the explanation below in detail.
In order to achieve the above purpose, the utility model provides a following technical scheme:
the utility model provides a scraper conveyor chain clamping device for scrape trigger and connect chain, includes steel sheet and horseshoe ring, the both ends at the steel sheet are connected on the upper portion of horseshoe ring, the lower part of horseshoe ring is equipped with the through-hole.
The upper parts of the horseshoe rings are welded at two ends of the steel plate.
The gap at the lower part of the horseshoe ring is larger than the chain diameter of the chain.
The size of the through hole is smaller than the inner width of the chain.
The length of the steel plate is matched with the width of the scraper conveyor.
The utility model discloses at least, can produce following technological effect:
the utility model discloses a horseshoe ring at both ends blocks and fixes the chain, has reduced appear when scraping trigger and connect the chain risk such as chain breaking, chain rupture and clamp finger, has reduced the field work personnel incident risk ratio.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention;
in the figure: 1-a steel plate; 2-horseshoe ring; 3-through holes.
Detailed Description
As shown in figure 1, a scraper conveyor chain clamping device for scraper conveyor connects chain, including steel sheet 1 and horseshoe ring 2, steel sheet 1 is 2cm thick steel sheet 1, the both ends at steel sheet 1 are connected on the upper portion of horseshoe ring 2, the lower part of horseshoe ring 2 is equipped with through-hole 3, blocks the chain through horseshoe ring 2 lower part, and can pass through-hole 3 and chain with fixed chain with the bolt.
As an alternative embodiment, the upper parts of the horseshoe rings 2 are welded at two ends of the steel plate 1, so that the connection firmness of the horseshoe rings 2 is ensured.
As an alternative mode, the gap at the lower part of the horseshoe ring 2 is larger than the chain diameter of the chain, so that the lower part of the horseshoe ring 2 can be clamped on the chain.
As an alternative embodiment, the size of the through hole 3 is smaller than the inner width of the chain, ensuring that the bolt can pass through the through hole 3 and the chain.
As an alternative embodiment, the length of the steel plate 1 matches the width of the scraper.
The utility model discloses the working process does:
when the scraper conveyor is extended, the chain at the head of the scraper conveyor is firstly disconnected, then the tail is pulled to a preset position, the chain at the backward third section chute at the tail is disconnected, corresponding chutes and chains are added, and finally the scraper conveyor chain clamping device is installed before the chain pressing block at the head of the scraper conveyor, and the scraper conveyor is arranged in a point mode to connect the chains.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention.
