Abstract
A contact net compensation device with a brake protection function for broken ropes comprises a fixed pulley, a movable pulley, a compensating rope, a cam, an adjustable push rod, an adjusting device as well as a fall lump string and connected and fixed accessories thereof. The compensation device is mounted on a pillar of the contact net and connected with the rope of the contact net; when in normal operation, through adjusting the adjusting device and the adjustable push rod and utilizing the tension of the compensating rope, the rim of the cam is enabled to keep a certain clearance with the compensating rope steadily without impacting the compensating rope. When the rope of the contact net is broken, the entire framework part loses balance and swings downward, and the push rod pushes the cam to rotate, so that the rim leans towards the fixed pulley and is in contact with the compensating rope in the fixed pulley; by utilizing the gravity of the fall lump string, the cam, the compensating rope and the fixed pulley can finish self-locking instantaneously, thereby achieving the purpose of quick and reliable brake.
Description
Technical field
The utility model relates to the tension compensating mechanism of contact nets in electrified railways, especially when broken string takes place contact system, can cut or polish jade with an emery wheel part braking in time to dwindle the compensating device of fault coverage to weighing down.
Background technology
At present, existing ratchet-type brake type compensating device is made of coaxial pulley and braking jacking block.Utilize jacking block to block the rotating disk ratchet during broken string and reach the braking purpose.This device is installed and complex process is transferred in inspection, carry out data computation according to on-the-spot temperature, clue parameter, causes fault otherwise may take place to compensate to lose efficacy; Because the no-load voltage ratio requirement causes this device volume bigger and heavy; This device processing technology and productive costs are higher.
Summary of the invention
In order to satisfy the demand of field application, the utility model provides a kind of compensating device, and this device not only has good compensation performance, and can be to weighing down the braking in time of stone roller part to dwindle fault coverage when broken string takes place contact system.
The technical scheme in the invention for solving the technical problem is: a cam is installed in the fixed pulley framework.During normal operation, the cam wheel rim has certain clearance with the compensation rope, and utilizes the tension force effect of compensation rope, this gap to keep stable, does not influence the compensation rope and moves.When broken string takes place in the contact system clue, the whole frame part lack of equilibrium bottom, the rotation of push rod actuating cam, make wheel rim rely on fixed pulley rapidly, contact with the compensation rope on the fixed pulley, and utilize the gravity that weighs down the stone roller string to make mechanism finish self-locking, reach the purpose of reliable braking rapidly in moment.
The beneficial effects of the utility model are, structure optimization, simple, and cost is low, and volume is little, and is in light weight, and installation, maintenance is easy.
Description of drawings
Below in conjunction with drawings and Examples this device is further specified.
Fig. 1 is mounting structure figure of the present utility model.
Fig. 2 is the constructional drawing of control apparatus among Fig. 1 (12).
Fig. 3 is the topology view of Fig. 1 cam (5).
Fig. 4 is the constructional drawing that can adjust push rod (13) among Fig. 1.
The specific embodiment:
In Fig. 1, fixed pulley (6) and cam (5) are installed in the framework (4) simultaneously, the driving surface of cam is designed to the circular arc groove face for adapting with compensation rope (7) diameter, the upper end of framework links with pillar (1) by dicyclo bar (3), the angle steel that casts anchor (2), cam, can adjust push rod (13), support the angle steel (14) and the angle steel that casts anchor to link in proper order, the compensation rope by framework (4), movable pulley (8) and fixed pulley with contact system clue (11) with weigh down cut or polish jade with an emery wheel go here and there (15) link.During normal operation, cam has certain clearance with the compensation rope, and utilizes the tension force effect of compensation rope, this gap to keep stable, does not influence the compensation rope and moves.When broken string takes place in the contact system clue, the whole frame part lack of equilibrium bottom, the rotation of push rod actuating cam, make wheel rim rely on fixed pulley rapidly, contact with the compensation rope in the fixed pulley, and the gravity that utilize to weigh down the stone roller string makes cam, compensation rope, fixed pulley finish self-locking in moment, reaches rapidly, the purpose of reliable braking.
