The traditional climbing mode that double safety belts move upwards in an alternative displacement mode is changed into the mode that the falling protector operates on one guide rail independently; the simple falling prevention device is reasonable in design, simple in structure, convenient to install, low in price, good in falling prevention effect and high in safety, operation personnel can climb an iron tower at ease only by tightly holding principal materials of the iron tower and stably stepping on foot nails or well using climbers, and casualty accidents are avoided to the maximum extent.
Description
Technical field
The utility model relates to transmission line of electricity falling proof device, while relating in particular to transmission line of electricity and transformer station's operation, and the upper and lower shaft tower of operating personnel and portal frame etc., protection operating personnel avoids the simple and easy falling proof device of transmission line of electricity from high falling.
Background technology
When transmission line of electricity and transformer station's work high above the ground, usually need to climb shaft tower or portal frame etc., in order to protect operating personnel's safety, the main method of moving in two safety belt trade-ofves that adopts of tradition is climbed, complicated operation, climbing speed is slow, and some staff do not want to take the trouble and even do not use; On the other hand, existing falling proof device is expensive, installing bothers, the required amount of labour is large, be difficult for promoting the popularization use, add the defect of design aspect, personnel, meet accident while falling, often can not lock well dragline, catching device along dragline toward gliding, really do not play the effect of fall arrest, cause the injured even personal injury of staff.Each power supply administration's falling from high altitude accident happens occasionally in recent years, and this has challenged the bottom line that electric power safety is produced greatly.Therefore, Red River power supply administration proposes the work safety policies of " safety is relied mainly on prevention, and healthy people-oriented, environment take protect as elder generation ", keeping the safety in production, Accident prevention bring up to critical positions.
Utility model content
Technical problem to be solved in the utility model is, overcome the above defect, provide a kind of transmission line of electricity cost low, simple in structure, install property easy, easy to use, safe good, climb the fireballing simple and easy falling proof device that is specially adapted to climbing electric transmission line shaft tower and transformer station's portal frame.
In order to solve the above technical problem, the simple and easy falling proof device of transmission line of electricity described in the utility model, comprises guide rail and catching device, and described guide rail comprises dragline, hanger and stringing bolt, and described dragline is connected with hanger by stringing bolt; Described catching device slides on dragline by the slideway in its metal support arm.
As improvement, the upper/lower terminal of dragline described in the utility model is provided with protective sleeve; The tooth place of stinging of described catching device is provided with anti-slop serrations.
Falling proof device described in the utility model is comprised of the catching device after improving and the most frequently used steel strand wires, hanger and the fastening bolt of power transmission lines overhauling, hanger is according to used working environment, the difference of the shapes such as the steel tower that will climb or cement pole, be made into corresponding shape, steel tower is normally made of steel, cement pole is isometrical cylindrical, so the shape of hanger also will change thereupon.Hanger is arranged on to the upper and lower suitable position of steel tower or cement pole, stringing bolt is installed on hanger, described dragline is connected with hanger by stringing bolt, and like this, guide rail is with regard to installation; During use, described catching device is connected between operating personnel's safety belt and dragline with it.Staff is by pin nail climbing steel tower or climbers climbing cement pole; when climbing up; catching device rises along dragline under the effect of self pulley; if staff's landing that meets accident in this process; stinging tooth will be pressed on dragline in catching device slideway in moment; guarantee that personnel are suspended in unlikely falling in the air moment, thereby play a protective role.
The beneficial effects of the utility model: owing to having used the above structure, the utility model changes the climbing mode of moving in the trade-off of traditional double safety belt into catching device isolated operation on a guide rail, reasonable in design, simple in structure, easy for installation, low price, fall arrest is effective, safe, and operating personnel only need do a good job of it iron tower main material, steps on steady steel tower pin nail or make to make good use of cement pole climber, relieved climbing, will avoid the generation of personnel casualty accidents to greatest extent.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The simple and easy falling proof device of the utility model transmission line of electricity, comprises guide rail 1 and catching device 2, and described guide rail 1 comprises dragline 3, hanger 4 and stringing bolt 5, and described dragline 3 is connected with hanger 4 by stringing bolt 5; Described catching device 2 slides on dragline 3 by the slideway 8 in its metal support arm 7.
As improvement, the upper/lower terminal of dragline 3 described in the utility model is provided with protective sleeve 6; Tooth 9 places of stinging of described catching device 2 are provided with anti-slop serrations 10.
Embodiment mono-: the present embodiment is for iron tower of power transmission line, described hanger 4 is made into angle steel shape, on hanger, weld with holes 11 brace 12, during installation, first by hanger 4 use wrench groups, approximately 1.5 meters, distance ground below steel tower, by the hole 11 on brace 12, stringing bolt 5 is installed, dragline 3 employing cross-sectional areas are the aluminum-cladding stranded wire of 50 square millimeters, aluminium alloy protective sleeve 6 is enclosed within on dragline 3, dragline 3 is fixing with steel wire clamp 16 through stringing bolt connecting hole, finally with press-connection machine, the oral area of protective sleeve 6 is compressed, in order to avoid staff is being hindered by dragline head while climbing, hanger and corresponding component are installed in the position needing above steel tower in the same way, and so complete guide rail is with regard to installation.During use, the hook 13 of described catching device hangs over to be worn on operating personnel's buckle for safety belts with it, and the other end of catching device is launched, and dragline 3 snaps in the slideway 8 in its metal support arm 7, and bail 14 is put into draw-in groove 15.The utility model is because tooth 9 places of stinging at catching device 2 are provided with anti-slop serrations 10; when staff meets accident landing, greatly strengthened the frictional force of stinging between tooth and dragline, moment is pressed on dragline in catching device slideway; guarantee that personnel are unlikely and fall, thereby play a protective role.
Embodiment bis-: the present embodiment is for cement pole, and described hanger 4 is made into circle, and stringing bolt 5 is directly installed on the junction of hanger 4, and dragline 3 employing cross-sectional areas are the aluminum-cladding stranded wire of 50 square millimeters, and all the other are with embodiment mono-.
These are only part embodiment of the present utility model, described anti-slop serrations 10 is made into sheet, and dragline 3 is aluminum-cladding stranded wire, and between sheet anti-slop serrations and aluminum-cladding stranded wire, snap-in force is good, and frictional force is large, strengthens fall arrest effect; Gap between slideway 8 in the pulley of described catching device and metal support arm 7 and the thickness of dragline 3 adapt, and increase the spring of catching device etc., all can make elastic force, frictional force increase, and strengthen fall arrest effect; If bar, tower are higher, also can set up hanger at guide rail middle part, in case dragline is started by strong wind; Situation and above embodiment for transformer station's portal frame are similar, as long as used the above structure, all should fall into protection domain of the present utility model.
