Abstract
The utility model provides a ladder is hung to portable contact net and supporting peg thereof, is including hanging a terraced body, it constitutes by the pole setting of a plurality of vertical ladders is articulated from beginning to end to hang terraced body to install the ratchet who goes on fixing a position articulated when adjacent vertical ladder expandes, last the installing of ratchet makes the pawl break away from the unblock handle of ratchet, hang and to install the couple on the vertical ladder on terraced body top, hang and to install an at least nylon tape on the horizontal pole of terraced body, the nylon tape forms one wholly with fixed all horizontal poles that make of every horizontal pole. The utility model has the advantages of the structure is light and handy, convenient to carry, polarization can be good, the range of application wide, be applicable to and replace the current ladder of hanging.
Description
Technical field
The utility model relates to a kind of portable contact net hanging ladder and supporting peg thereof.
Background technology
Contact net is responsible for the vital task electric energy obtained from traction substation directly being flowed to the use of motor locomotive.Therefore the quality of contact net and duty will directly affect the transport capacity of electric railway.Because contact net is outdoor layout, and it is not for subsequent use, load on circuit is again move along contact wire along with the operation of electric locomotive and change, therefore regular maintenance is carried out to contact net, particularly under accident conditions, can become very important with rapid power transmission of recovering by rapid rush-repair, contact net hanging ladder safeguards and rush to repair one of indispensable instrument, but on the one hand, due to contact net having high voltage, therefore the liftoff height of contact net, general 5-10 rice, therefore cause hanging ladder length long, be inconvenient to carry and transport, on the other hand, first will hanging ladder be hung on transmission pressure before carrying out safeguarding and overhauling, but the complex circuit on contact net, the mode now hanging ladder being hung up transmission pressure is all adopt people to hold up the bottom of hanging ladder, hook on head end is hung up transmission pressure, but because hanging ladder height is high, be easy to rock in the process of operation, cause hanging wrong position or touching high-tension line, thus cause circuit to damage or serious casualties, therefore existing hanging ladder in actual applications all very unreasonable.
Utility model content
The purpose of this utility model be to overcome the deficiencies in the prior art and defect and a kind of light structure is provided, easy to carry, positioning performance good, the portable contact net hanging ladder of applied range and supporting peg thereof.
To achieve these goals, the technical scheme that the utility model adopts is:
A kind of portable contact net hanging ladder, comprise hanging ladder body, described hanging ladder body is formed by the vertical rod head and the tail of multiple vertical ladder are hinged, and in hinged place, ratchet mechanism is installed, described ratchet mechanism is provided with the release lever making ratchet depart from ratchet, the vertical ladder on described hanging ladder body top is provided with hook, the cross bar of described hanging ladder body is provided with at least one nylon tape, described nylon tape and every root cross bar fixedly make all cross bar shapes in aggregates.
The length of described vertical ladder is 1 ~ 1.5m.
The width of described vertical ladder is 400 ~ 600mm.
The peg that a kind of portable contact net hanging ladder is supporting, comprise insulating bar, the end of described insulating bar is provided with pulley and location hook, described pulley is provided with rope, one end of described rope is fixed with the convenient butt hook be connected with the cross bar of hanging ladder body, make when the other end of rope pulls downwards, butt hook drives hanging ladder body to move upward.Described pulley is fixed pulley.
Owing to adopting such scheme, the utility model adopts folding mode, is hinged together, and is provided with ratchet mechanism in hinged place by often saving the vertical ladder head and the tail of length at 1 ~ 1.5 meter, adjacent vertical ladder after launching is positioned, thus making the vertical ladder after launching form entirety, handled easily personnel climb, after having overhauled, control ratchet by the release lever of ratchet mechanism and depart from ratchet, thus make vertical ladder return, and convenient folding, storage.The cross bar of hanging ladder is provided with two nylon tapes in left and right, and every root nylon tape is connected with every root cross bar and makes its shape in aggregates, prevents the aging or cross bar of frame for movement from coming off and causes terraced generation of going up personnel's accident, play the effect of second protection.
And this device is by supporting peg, the top of peg is provided with fixed pulley, rope and location hook, what peg adopted on the one hand is insulating bar, prevent from getting an electric shock, on the other hand, peg is light, good operation, more easily accurately hang on contact net, therefore first by location hook, peg is hung on contact net, the butt hook of rope one end is fixed on the cross bar of hanging ladder top, then people pulls the other end of rope, utilize fixed pulley by hanging ladder to pull-up, hanging ladder is upwards lifted by operating personnel simultaneously, such rope serves the effect of location and lifting, make when the operation of V-arrangement skylight, the upper end of hanging ladder can not disorderly be rocked, high-voltage line can not be touched, thus ensure that the safety of operating personnel.

Fig. 1 is the structural representation of the utility model hanging ladder.
Fig. 2 is the elevation of the utility model hanging ladder.
Fig. 3 is the structural representation of the utility model peg.
Detailed description of the invention
Below in conjunction with accompanying drawing, further describe the detailed description of the invention of this patent.
As shown in Figures 1 to 3, a kind of portable contact net hanging ladder, comprise hanging ladder body, described hanging ladder body is formed by vertical rod 11 head and the tail of multiple vertical ladder 1 are hinged, and ratchet mechanism 2 is installed in hinged place, thus adjacent vertical ladder 1 is positioned upon deployment, described ratchet mechanism 2 is provided with the release lever 3 making ratchet depart from ratchet, the vertical ladder 1 on described hanging ladder body top is provided with hook 4, the cross bar 12 of described hanging ladder body is provided with at least one nylon tape 5, described nylon tape 5 fixedly makes all cross bars 12 shape on hanging ladder body in aggregates with every root cross bar 12.The length of described vertical ladder 1 is 1 ~ 1.5m.The width of described vertical ladder 1 is 400 ~ 600mm.
The peg that a kind of portable contact net hanging ladder is supporting, comprise insulating bar 6, the end of described insulating bar 6 is provided with fixed pulley 7 and location hook 9, described fixed pulley 7 is provided with rope 8, one end of described rope 8 is fixed with the convenient butt hook be connected with the cross bar 12 of hanging ladder body, make when the other end of rope 8 pulls downwards, butt hook drives hanging ladder body to move upward.
In use, be hinged together often saving vertical ladder head and the tail, positioned the adjacent vertical ladder after expansion by ratchet mechanism, thus make the vertical ladder head and the tail after launching be connected to form entirety, handled easily personnel climb, after having overhauled, after having overhauled, control ratchet by the release lever of ratchet mechanism and departed from ratchet, thus made vertical ladder return, convenient folding, storage.Then by location hook, peg is hung on contact net, again the butt hook of rope one end is fixed on the cross bar of hanging ladder top, then people or machine pull the other end of rope, utilize fixed pulley by hanging ladder to pull-up, hanging ladder is upwards lifted by operating personnel simultaneously, and such rope serves the effect of location and lifting, make when the operation of V-arrangement skylight, the upper end of hanging ladder can not disorderly be rocked, and can not touch high-voltage line, thus ensure that the safety of operating personnel.
