Abstract
The utility model discloses a grounding short-circuit device for a bottom contact type contact rail system. The device can be used for the maintenance of a metro contact rail system and the emergency evacuation of passengers. The device consists of a body, claw-shaped clips and connecting cables. The grounding short-circuit device for the bottom contact type contact rail system can be used for the two conditions of metro maintenance and emergency evacuation. One end of the body directly contacts with a contact rail, and the other end of the body is connected with a steel rail by tightly pressing the cables through the claw-shaped clips. The device can be used for preventing a maintainer from an electric shock during the maintenance of the contact rail system, and can also be used for forcibly cutting off the power of the contact rail system to protect the safety of the passengers and rescuers.
Description
Affiliated technical field
The utility model relates to the ground short circuit device using in a kind of lower contact type contact rail system, especially charged contact rail system can be forced to the ground short circuit device of power-off.
background technology
At present, the structure of ground short circuit device is comprised of with the cable that is connected them two hooked rod.In use, electric power control cabin needs first contact rail systematic electricity to be cut off, then with a hook, catch on the rail as negative pole, a hook catches on as anodal contact rail, be about to anodal and negative pole short circuit, make the contact rail system cannot be charged suddenly, then can carry out the work of contact rail system maintenance.But, if subway train goes wrong, need to evacuate passenger, rescue worker need to enter scene and carry out rescue work, and at this moment electric power control cabin can not be in time or contact rail systematic electricity cannot be broken at all, passenger or rescue worker just have the danger that touches contact rail system and occur to get an electric shock.
summary of the invention
In order to overcome existing ground short circuit device, contact rail systematic electricity can not be forced to the deficiency of breaking, the utility model provides a kind of ground short circuit device, this ground short circuit device, by cable and claw type clamp, rail and contact rail are linked in sequence, body one end directly connects contact rail, and the other end compresses cable by claw type clamp and connects rail.This ground short circuit device is used in the time of not only can be for contact rail system maintenance, prevents that maintainer from getting an electric shock, and the electric power in contact rail system can be forced break, protection passenger and rescue worker's safety.
The utility model solves the technical scheme that its technical matters adopts: ground short circuit device is comprised of body, claw type clamp and connecting cable.When using as maintenance function, arriving first electric power control cabin breaks contact rail systematic electricity, then with claw type clamp, block rail, again by body frame near on the rail of contact rail, move body handle, contact block on body is contacted with contact rail, realized the short circuit between uncharged contact rail and rail is connected, maintainer can keep in repair contact rail system; When using as pressure power down function, not needing to arrive first electric power control cabin breaks contact rail systematic electricity, directly with claw type clamp, block rail, by body frame near on the rail of contact rail, move body handle, contact block on body is contacted with contact rail, realized the short circuit between charged contact rail and rail has been connected, short circuit connects and will produce large short circuit current, large short circuit current will make the insurance moment fusing of electric power control cabin, thereby realizes the object that contact rail systematic electricity is broken.
The beneficial effects of the utility model are; a kind of ground short circuit device has two kinds of effects; in the time of not only can be for contact rail system maintenance, use; prevent that maintainer from getting an electric shock; and the electric power in contact rail system can be forced to break; protection passenger and rescue worker's safety, realized multiple use, very convenient when using and carry.
accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is 3 dimensional drawing of the present utility model.
Fig. 2 is the contact block view of short circuit connecting device body.
Fig. 3 is claw type clamp view.
1. bodies in figure, 2. claw type clamp, 3. clamp cable, 4. body cable, 5. contact rail, 6. rail, 7. contact block, 8.U shape piece, 9. strong magnet, 10. clamping lever, 11. snap fits, 12. connecting rods, 13. connection covers.
The specific embodiment
In Fig. 1, body (1) one end is connected with contact rail (5), and other end frame is on the close rail (6) of contact rail (5).Clamp cable (3) be connected contact rail (5) and rail (6), realized using the contact rail as anodal (5) with as the rail (6) of negative pole and carried out short circuit connection.No matter whether contact rail is charged, and the using method of ground short circuit device is all the same.First use claw type clamp (2) that clamp cable (3) end is fixed to rail (5) upper, then rotate body (1) its one end is contacted with contact rail (5).For ensuring personal safety, prevent flash burn eyes, when body (1) contacts with contact rail (5), unavailable eyes are checked the situation of body (1) end and contact rail (5) contact position.
In embodiment illustrated in fig. 2, it is upper that contact block (7) is connected to body (1) by U-shaped piece (8), on contact block (7)
Be fixed with strong magnet (9), the structure interval of appropriate design strong magnet (9) and contact block (7) and contact rail (5), while making ground short circuit device busy, the magnetic force that contact block (7) can rely on strong magnet (9) and contact rail (5) remain and contact and strong magnet (9) does not contact with contact rail (5).
In the embodiment shown in fig. 3, by rotating clamping lever (10), can make connecting rod (12) move, thereby drive snap fit (11) opening and closing.When clamping lever (10) moves downward, snap fit (11) can clamp rail (6), now also simultaneously the connection cover (13) linking together with clamp cable (3) can be pressed to rail (6) upper in the bottom of clamping lever (10), realized quick being connected of clamp cable (3) with rail (6).
Claims (3)
1. a ground short circuit device, is linked in sequence rail and contact rail by cable and claw type clamp, it is characterized in that: body one end directly connects contact rail, and the other end compresses cable by claw type clamp and connects rail.
2. ground short circuit device according to claim 1, is characterized in that: contact block and the strong magnet of body end are fixed together, and contact block is connected with contact rail by magnetic force.
3. ground short circuit device according to claim 1, is characterized in that: cable and connection cover are connected as a single entity, and can pass through claw type clamp and rail Fast Installation.
