Auxiliary device more particularly to a kind of waterproof cloth trolley steel cable tensioner the utility model is related to a kind of waterproof cloth trolley
Device.
Background technology
Waterproof cloth trolley is a kind of for laying the engineering trolley of waterproof cloth in tunnel, and basic principle is：Utilize peace
Hoist engine in the middle part of trolley drives steel cable, and the both sides of trolley are distributed steel cable respectively, and the crown center position installation of trolley is anti-
Water cloth, the steel cable of both sides drive waterproof cloth on the circular inner wall that both sides and lower section are laid in tunnel respectively.In the course of work, point
Cloth pulls waterproof cloth and moving parts in trolley both sides and by the steel cable that hoist engine drives, and makes waterproof cloth and moving parts in platform
The moving on rails of vehicle both sides.
In practical application, due to track precision not enough, the change in location of waterproof cloth lead to the tension variations of steel cable, in addition
The flexible sexual factor of steel cable itself, eventually leading to the elasticity of steel cable itself can change in different time, due to steel cable with
Hoist engine moves steel cable by frictional force, and the variation of the elasticity of steel cable may make change in friction force, in steel cable and volume
When raising that friction is small between machine, steel cable can skid on hoist engine, and eventually leading to can not work.
The previous method that is commonly used to solve problem above is：Counterweight is hung on steel cable（Such as the cement block of constant weight）,
Steel cable is effectively tensed by the gravitation energy of counterweight itself, to ensure the frictional force of steel cable and hoist engine.However this method makes counterweight
In the air, steel cable constantly rubs with the pulley in counterweight, is easy to cause steel rope breaking, so as to cause safety accident for suspention.
