Description
Technical field
The present invention relates to a kind of auxiliary devices of waterproof cloth trolley more particularly to a kind of waterproof cloth trolley steel cable tensioner to fill
It puts.
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 of hoist engine drive, 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 cause the tension variations of steel cable, in addition
The flexible sexual factor of steel cable itself, ultimately resulting in 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
Raise frictional force between machine it is smaller when, steel cable can skid on hoist engine, and ultimately resulting in can not work.
Being commonly used to the method for solution problem above in the past 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 trigger security incident for suspention.
The content of the invention
The purpose of the present invention is that solve the above-mentioned problems and provides a kind of safe and reliable waterproof cloth trolley steel cable
Swelling device.

In said structure, body frame is used as the installation foundation of entire steel cable swelling device, and concrete structure is according to actual needs
Depending on, as long as meeting requirement；Screw is used as the installation foundation of spring and coordinates the tune for realizing spring stress with nut
Section；On the one hand spring realizes the automatic adjusument by a small margin of the vertical position of movable pulley by the stress of itself, so as to fulfill
The automatic adjusument by a small margin of the tensioner degree of steel cable, on the other hand by screw drive realize movable pulley vertical position compared with
Significantly adjust the adjusting by a relatively large margin with the tensioner degree of steel cable；Movable pulley is used for and movable pulley mounting base, spring and silk
Bar cooperation realizes that the vertical position of itself is adjusted, and is adjusted so as to fulfill the tensioner degree of steel cable；Fixed pulley and fixed pulley are installed
Seat cooperation is realized to the positioning of steel cable and deflecting function, so as to which the tensioner degree that movable pulley is coordinated to realize steel cable is adjusted.
Movable pulley level, which chooses to install, in order to prevent influences steel cable movement, and the movable pulley mounting base is non-circular and by institute
Stating the vertical frame /V of body frame prevents it from rotating and can only move up and down in the horizontal direction；For the ease of processing, the activity is sliding
Mounting base is taken turns to be square, the vertical frame of the body frame surrounds to form lateral cross section as square central space.
Specifically, the crossbearer of the body frame is horizontal steel plate, and the vertical frame of the body frame is two double flute steel, the double flute steel
Both ends be welded to connect respectively with two horizontal steel plates, the horizontal steel plate for installing the screw is equipped with for described
The screw through hole that screw passes through, the horizontal steel plate of lower part are equipped with the steel cable through hole passed through for the steel cable.
Specifically, installation there are two the first otic placode, is pacified between two first otic placodes in the movable pulley mounting base
Equipped with the first axis pin, the middle part of the movable pulley is equipped with clutch shaft bearing, and the clutch shaft bearing is sleeved on first axis pin；
The fixed pulley mounting base is two the second otic placodes, and the second axis pin, the fixation are equipped between two second otic placodes
The middle part of pulley is equipped with second bearing, and the second bearing is sleeved on second axis pin.
In order to realize better steel cable tensioner effect, the diameter of the movable pulley is more than the diameter of the fixed pulley.
For the ease of the vertically movable of control leading screw, the outside of the nut is equipped with the rotation for nut described in manual rotation
Change hands handle.
For the ease of rotating nuts, gasket is equipped between the nut and the body frame.
Specifically, the upper end of the screw is connected after passing through the crossbearer of the body frame with the nut, under the screw
End is connected with the spring, and the spring is tension spring, and two fixed pulley mounting bases are respectively arranged under the body frame
The both sides in portion.
The beneficial effects of the present invention are：
The present invention by set movable pulley and by spring and screw come realize the vertical position of movable pulley by a small margin from
It adapts to adjust and adjust manually by a relatively large margin, make waterproof cloth trolley steel cable either causes elasticity small because usage time is too long
Amplitude reduction is still because the variation of trolley component locations, which makes the elasticity of steel cable reduce by a relatively large margin, can realize elasticity
Quick to adjust, efficiently solving steel cable in use can not normal work caused by the steel cable elasticity variation caused by a variety of causes
The problem of making, and counterweight is not required to, while steel cable and pulley contact, friction is reduced, avoids the risk of steel rope breaking, is used
Securely and reliably.
