The guide pulley type pendant limiting system is characterized in that a guide frame is connected between the upper support frame and the lower support frame; a pendant is connected between an upper guide pulley pendant and a lower guide pulley pendant to form a pendant; the upper guide pulley pendant and the lower guide pulley pendant are slidably connected with a guide groove of the guide frame through a guide pulley assembly; and the pendant is limited between the guide pulley pendant and a guide rail. The invention provides a guide pulley type pendant limiting system with the advantages of reasonable structural design, convenient adjustment, high strength, reliable use and capability of meeting the requirement on the development of a high-speed electric railway.
Description
Technical field
The present invention relates to the contact nets in electrified railways system, being applicable to particularly that the contact nets in electrified railways system casts anchor to rise in the compensating device adjusts the used bob stone roller of catenary or contact wire compensation tension force and guiding and weighs down stone roller and move up and down and limit and weigh down stone roller and cause the bob stone roller restraint device of swing, the guide pulley type pendant limiting system of saying so accurately by wind.
Background technology
It is that driving produces wind eddies stream or has under the wind condition restriction weigh down the stone roller swing that common bob stone roller restriction frame mainly acts on, and anti-falling stop stone roller is invaded limit.But at the big section of wind-force such as strong wind section, coastal typhoon zone, because of weighing down the effect of stone roller swing, cause thread tension force to change greatly, the property at any time of wind direction simultaneously causes very big influence to the safety of clue, has reduced the safety factor of entire mechanism.For this reason, we to have designed a kind of novel bob stone roller restraint device that can use at the big section of wind-force such as strong wind district, coastal typhoon zone be the guide pulley type pendant restraint device.
Disregarding wind-force, wind direction to weighing down under the perfect condition of cutting or polish jade with an emery wheel beat, owing to weigh down the effect of stone roller self gravitation, when temperature Change, the autoregulation of compensating device makes clue relaxation degree keep substantially constant, thereby guarantee the normal operation of electrified railway, the characteristics of Here it is traditional mechanism.Generally be made up of conduit, anchor ear and other union piece, anchor ear plays the effect that the stone roller beat is weighed down in restriction.But at the big section of wind-force such as strong wind section, coastal typhoon zone, weigh down stone roller and be subjected to wind effect, beat is bigger, and the safety of clue is caused very big influence.
Summary of the invention
The purpose of this invention is to provide a kind of reasonable in design, easy to adjust, intensity is high, use is reliable, can satisfy the guide pulley type pendant limiting system of high-speed electric railway demand for development.
The object of the present invention is achieved like this, guide pulley type pendant limiting system, comprise the column that is fixed on the basis, the column upper-lower position respectively is fixed with a upper support frame and a lower support frame, it is characterized in that: connect guide frame between upper support frame and the lower support frame, last leading sheave weighs down to connect between stone roller and the following leading sheave bob stone roller and weighs down stone roller, form and weigh down stone roller integral body, last leading sheave bob stone roller and following leading sheave weigh down the guide groove formation sliding block joint of cutting or polish jade with an emery wheel by leading sheave assembly and guide frame, weigh down stone roller and are limited between leading sheave bob stone roller and the guide rail.
Connect one group or two groups of guide frame between described upper support frame and the lower support frame, there is last leading sheave to weigh down stone roller and following leading sheave bob stone roller in every group of guide frame, it is to weigh down stone roller that last leading sheave weighs down between stone roller and the following leading sheave bob stone roller, form two groups and weigh down stone roller integral body, last leading sheave bob stone roller and following leading sheave weigh down the guide groove formation sliding block joint of cutting or polish jade with an emery wheel by leading sheave assembly and every group of guide frame, weigh down stone roller and are limited between leading sheave bob stone roller and the guide rail.
The described leading sheave of going up weighs down stone roller and following leading sheave and weighs down to cut or polish jade with an emery wheel and can choose 2 groups or 3 groups or 4 groups of leading sheave assemblies are connected with guide frame.
Described upper support frame and lower support frame and guide frame connect into monolateral framed structure or bilateral framed structure.
Described upper support frame and lower support frame and guide frame constitute monolateral framed structure, and last leading sheave weighs down stone roller and following leading sheave and weighs down to cut or polish jade with an emery wheel and choose 2 groups or 4 groups of leading sheave assemblies and be connected with guide frame.
Described guide frame is a vertically-guided frame, between upper support frame and a lower support frame a middle bracing frame is arranged, and connects a vertically-guided frame between upper support frame, middle bracing frame and the lower support frame.
Described leading sheave assembly comprises the leading sheave and the axis of guide, between the leading sheave and the axis of guide bearing is arranged.
Two ends adopt " O " RunddichtringO to seal between the described leading sheave and the axis of guide.
Described upward leading sheave weighs down stone roller and following leading sheave bob stone roller is that steel structure welds body or foundry goods.
Described guide frame is channel-section steel or pipe or I-beam section or angle steel etc.
Advantage of the present invention is: owing to weigh down stone roller and following leading sheave bob stone roller based on leading sheave in the guide rail guide frame structure qualification of vertically holding up guide frame, last leading sheave weighs down to connect between stone roller and the following leading sheave bob stone roller and weighs down stone roller, so just define to weigh down and cut or polish jade with an emery wheel and in guide rail, to slide up and down, thereby restriction wind-force deflection angle, whole bob stone roller side-play amount is 2mm to the maximum, the bob stone roller beat that actv. has been avoided causing because of wind-force, wind direction is bigger, solved thread tension force and changed big problem.Leave little and suitable gap between leading sheave and guide rail, guide wheel and guide rail belong to rolling friction character, so frictional resistance is very little, and unnecessary catching phenomenon, unlikely reduction mechanical efficiency take place when having avoided up-and-down movement.Weigh down simultaneously the stone roller restraint device be designed to adjustable, the convenient manufacturing and the on-site installation adjustment, the contact contact wire that has guaranteed the block of bow collector of electric locomotive safety and steady slides and is subjected to electricity to get stream.
