Abstract
The utility model belongs to the technical field of compensation equipment for railway electrified route, particularly discloses a ratchet wheel compensation device for high-speed electrified contacting net, which is technically characterized in that the utility model comprises a connecting arm and a stop gear fixed on a ratchet wheel bracket through a pin, the ratchet wheel body is arranged on the connecting arm, ratchets are formed on the ratchet wheel body, stop teeth are formed on the stop gear, the ratchet adopts a regular triangle shape, and the stop tooth adopts a regular triangle shape matched with the shape of the ratchet. When disconnection happens, the ratchet wheel body moves downward rapidly round the pin under the action of balance weight, then the ratchet wheel body is meshed with the stop teeth, and both the stop teeth and the ratchets adopt regular triangle shapes, the contact area thereof is large, and the stop teeth and the ratchets are not easy to be interrupted, thereby prolonging the service life, reducing the maintenance cost and preventing the accident.
Description
Technical field
The utility model belongs to railway electrification line build-out equipment technical field, relates in particular to high speed railway electrified contacting nets ratchet compensating device.
Background technology
Along with the speed-raising of train, higher requirement is proposed also for high speed railway electrified contacting nets tension force and compensation way.The high speed railway electrified contacting nets that uses adopts the helical teeth ratchet with ratchet compensating device at present, stop tooth is pointed, this structure is when counterweight is light, still can exempt from strong reply, but strengthen for present net tension force, counterweight increases the weight of, and the helical teeth ratchet is difficult to bear, be easy to ratchet and stop tooth are interrupted, cause unnecessary loss.
The utility model content
The technical problems to be solved in the utility model just provides a kind of be not easy to interrupt ratchet and stop tooth, safe in utilization, long service life, high speed railway electrified contacting nets ratchet compensating device that maintenance cost is low when counterweight is big.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: high speed railway electrified contacting nets ratchet compensating device, comprise by bearing pin and be fixed on connecting arm and stop motion mechnism on the ratchet wheel frame, described connecting arm is provided with the ratchet body, described ratchet body is provided with ratchet, described stop motion mechnism has stop tooth, and described ratchet is an equilateral triangle, and described stop tooth is the equilateral triangle that mates with described ratchet shape.
Its additional technical feature is:
Described stop motion mechnism comprise the check plate that has stop tooth and and be fixed on strut bar on the ratchet wheel frame, between described strut bar and check plate, be provided with elastic mechanism;
Described elastic mechanism is a spring;
Be provided with limited post in described check plate side, be provided with position-limited trough with described limited post correspondence position on described connecting arm, described limited post penetrates in the position-limited trough;
Described stop tooth is more than two.
High speed railway electrified contacting nets ratchet compensating device provided by the utility model, compared with prior art, have the following advantages: one, owing to comprise by bearing pin and be fixed on connecting arm and stop motion mechnism on the ratchet wheel frame, described connecting arm is provided with the ratchet body, described ratchet body is provided with ratchet, described stop motion mechnism has stop tooth, and described ratchet is an equilateral triangle, and described stop tooth is the equilateral triangle that mates with described ratchet shape, when broken string takes place when, the ratchet body moves down rapidly around bearing pin under the effect of counterweight, ratchet body and stop tooth engagement, stop tooth and ratchet are all equilateral triangle, area of contact is big, is not easy to interrupt stop tooth and ratchet, has prolonged service life, reduce maintenance cost, prevented the generation of accident; They are two years old, since described stop motion mechnism comprise the check plate that has stop tooth and and be fixed on strut bar on the connecting arm, between described strut bar and check plate, be provided with elastic mechanism, like this, broken string ratchet body is taking place when bearing pin moves down rapidly, in ratchet body and the stop tooth engagement process, the engagement of ratchet body and stop tooth contact moment and becomes the Elastic Contact with certain buffering by the rigidity contact, has avoided rigidity to contact the damage that causes ratchet and stop tooth; Its three owing to be provided with limited post, on described connecting arm, be provided with position-limited trough with described limited post correspondence position in described check plate side, described limited post penetrates in the position-limited trough.So just can control time and distance that ratchet broken string back falls; Its four because described stop tooth is more than two, reduced the stressed of each stop tooth, prevented that existing single stop tooth is stressed excessive and damage, cause the accident but also can prevent that existing single stop tooth from damaging.
Description of drawings
Fig. 1 is the structural representation of high speed railway electrified contacting nets with the ratchet compensating device normal operating condition;
Fig. 2 is the structural representation that the high speed railway electrified contacting nets is used ratchet compensating device under the broken string state.
The specific embodiment
Below in conjunction with accompanying drawing structure and the use principle of the utility model high speed railway electrified contacting nets with ratchet compensating device is described in further details.
As depicted in figs. 1 and 2, the utility model high speed railway electrified contacting nets comprises ratchet body 2 and the stop motion mechnism 7 that is fixed on the connecting arm 9 with ratchet compensating device, connecting arm 9 is fixed on the ratchet wheel frame 1 by bearing pin 6, ratchet body 2 is provided with ratchet 21, have stop tooth 71 at stop motion mechnism 7, the side view of ratchet 21 is an equilateral triangle, and stop tooth 71 is the equilateral triangle with ratchet 21 form fit.Like this, when broken string takes place when, ratchet body 2 moves down rapidly around bearing pin 6 under the effect of counterweight, ratchet body 2 and stop tooth 71 engagements, stop tooth 71 is all equilateral triangle with ratchet 21, area of contact is big, is not easy to interrupt stop tooth 71 and ratchet 21, has prolonged service life, reduce maintenance cost, prevented the generation of accident.
Stop motion mechnism 7 comprises the check plate 72 that has stop tooth 71 and is fixed on strut bar 11 on the ratchet wheel frame 1, be provided with elastic mechanism 73 between strut bar 11 and check plate 72.Like this, broken string ratchet body 2 is taking place when bearing pin 6 moves down rapidly, in ratchet body 2 and stop tooth 71 engagement processes, 71 engagements of ratchet body 2 and stop tooth contacts moment and become the Elastic Contact with certain buffering by the rigidity contact, have avoided the rigidity contact to cause the damage of ratchet 21 and stop tooth 71.Elastic mechanism 73 can be spring, also can be other elastic mechanisms.
In order to control time and the distance that ratchet broken string back falls, be provided with limited post 74 in the side of check plate 72, on connecting arm 9, be provided with position-limited trough 91 with limited post 74 correspondence positions, limited post 74 penetrates in the position-limited trough 91.
For having prevented existing single stop tooth 71 stressed excessive damages, cause the accident but also can prevent to have now single stop tooth damage, stop tooth 71 is two or more.So just reduced the stressed of each stop tooth.
The foregoing description is just to explanation of the present utility model; therefore; protection domain of the present utility model not only is confined to the foregoing description, as long as structure is identical with ratchet compensating device with the utility model high speed railway electrified contacting nets, just drops on the scope of the utility model protection.
