Problems solved by technology

However, the speed of the motor is high, the impact force is large, and the pre-tensioning force of the chain is difficult to determine. The chain is tensioned entirely by the experience of the on-site staff, which may easily cause the problem of the chain being too tight or too loose, and it is difficult to ensure the tightness of the scraper chain. Work can be done safely and efficiently

Abstract

The invention provides a chain tightening device. The chain tightening device comprises a connecting base, a first brake clamp arm, a second brake clamp arm and a driving mechanism, wherein the firstbrake clamp arm is provided with a first clamping end and is in pivot connection with the connecting base; the second brake clamp arm is provided with a second clamping end and is in pivot connectionwith the connecting base, and the second brake clamp arm and the first brake clamp arm are oppositely arranged; the driving mechanism comprises a force measuring assembly and is connected with the first brake clamp arm and the second brake clamp arm; and the force measuring assembly is used for measuring clamping force generated between the first clamping end and the second clamping end. Accordingto the chain tightening device disclosed by the technical scheme, due to the fact that the force measuring assembly can measure the clamping force generated between the first clamping end and the second clamping end, field personnel can accurately know the magnitude of brake force of a brake disc, the field personnel can conveniently adjust the brake force of the brake disc, then the field personnel can conveniently adjust the magnitude of pre-tightening force of a chain, and the chain tightening work on site is ensured to be safely and efficiently completed.

Description

technical field [0001] The invention relates to the technical field of scraper chain tensioning, in particular to a chain tensioning device. Background technique [0002] At present, the degree of tension of the scraper chain directly affects the running state and performance of the scraper conveyor. If it is too tight, it will increase the wear and power loss of the chain. The occurrence of chain and broken chain accidents may lead to on-site safety accidents. [0003] In the related art, the chain is tightened directly through the cooperation of the motor of the scraper conveyor with the chain tightening device, and the chain tightening device is used to brake the brake disc of the motor. However, the speed of the motor is high, the impact force is large, and the pre-tensioning force of the chain is difficult to determine. The chain is tensioned entirely by the experience of the on-site staff, which is easy to cause the problem of too tight or too loose the chain, and it ...
