Abstract

The utility model discloses a prismatic standpipe falling prevention device, which is provided to resolve the problems of existing round standpipe falling prevention device that a plurality of consumed materials and high transportation and installation costs for the bridge connected with upright pole of similar height to the wire pole tower. The utility model comprises a standpipe connected and fixed in parallel with the lateral side of longitudinal angle steel with shackles in the wire pole tower and a falling prevention device connected to a waist band of people via rope and hung outside the pipe wall of the standpipe. The standpipe has prismatic axial section; the wall of a short axis tube is connected and fixed with the lateral side of an angle steel; the falling prevention device is smocked outside the opposite side of the long axis of the prismatic standpipe. Because the axial section of the standpipe has prismatic shape, the wall of the short axis tube can be fixed firmly to the electric wire pole tower. Besides, the falling prevention device, which is smocked outside the opposite side of the long axis of the prismatic standpipe, can slide up and down along the external wall of the standpipe, thus omitting the configuration of the standpipe with similar height to that of the electric wire pole tower, reducing the amount of consumed materials to half of that for the existing round standpipe and greatly lowering down the installation cost and the cost on transporting the materials to the project site.

Description

Prismatic standpipe falling proof device

Technical field

The utility model belongs to safety device, and specifically a kind of people climbs work high above the ground, can prevent the device that human body falls from the high-altitude when the mobile process of climbing neutralizes operation aloft up and down.

Background technology

The people climbs work high above the ground, must guarantee in the process of climbing and the personal safety of overall process during operation aloft.For example to the wire pole tower of power transmission engineering, work, the height of shaft tower is generally more than 15 meters, set up high-voltage line and regular maintenance and repair in the above to circuit, all to climb to its top along the pin nail of electric pole or iron tower, during the transferring position of more than entering cross-arm or on lead, working, the staff hangs over safety belt fixing back work on the fixture such as electric wire cross-arm, just can make the personal safety problem of work high above the ground guaranteed, and for climbing the process that moves up and down, in case physical fatigue or energy occurring does not concentrate and slips, very easily cause human casualty accident, consequence is hardly imaginable.

Current, in the industry, can solve an above-mentioned difficult problem, the for example present falling proof device that uses, be with the electric pole of pin nail, a side of pylon from bottom to top, height along cat ladder is fixed with vertical rod, and circular standpipe and vertical rod secured in parallel are in vertical rod, and the hook of " C " shape or "T"-shaped anti-falling device is hooked on the circular standing tube outer wall, its pommel ties up on staff's waistband with rope, can make anti-falling device with about the suitable circular standpipe of human body.When the careless pin of people when pin nails on slippage, anti-falling device tilts with the human body tenesmus, the mouth of hook on it is stuck on the outer wall of circular standpipe firmly, and the people can not weighed down down from the high-altitude, it has had assurance safely.Setting up vertical rod between circular standpipe and the electric wire pylon, is for standpipe can be firmly fixed, again not overslaugh anti-falling device sliding up and down on circular standing tube outer wall.Be about to standpipe and make closely to be fixed on by phased manner the vertical rod side up and down, with anchor ear vertical rod is connected on electric pole or the pylon securely again, the bridge that vertical rod connects as standpipe with the polylith steel plate.Because many and electric wire pylon with high vertical rod, increase consumable quantity, the cost that has also strengthened transportation simultaneously and installed greatly.

The utility model content

Technical problem to be solved in the utility model is, overcoming the circular vertical pipe type falling proof device of existing usefulness need make the high shortcoming of cost that the bridge consumptive material is many, transportation is installed that standpipe connects with high vertical rod with the wire pole tower frame, and a kind of prismatic standpipe falling proof device is provided.

In order to solve the problems referred to above that prior art exists, the utility model is to adopt following technical proposals to realize: falling proof device comprises and the vertical angle steel parallel sided of electric wire pylon upper belt foot nail and the standpipe of fixedlying connected, falling on it fixes the parts handle and links to each other, overlaps the anti-falling device that hangs over outside the standpipe tube wall with people's waistband with rope, described standpipe is that shaft section is the prismatic standpipe of prismatic, its minor axis tube wall is fixedlyed connected with the angle steel side, and the anti-falling device cover hangs over outside the tube wall of major axis opposite side of prismatic standpipe.

The utility model also has following technical characterictic:

Described angle steel parallel sided and fixedly connected prismatic standpipe, be on the exterior angle of the vertical angle steel of electric pole pylon, whenever keep at a certain distance away and laterally be provided with the right angle keratotic plug, the interior angle of keratotic plug is attached on the exterior angle of angle steel, the keratotic plug two ends are installed with the edge pad that may be stuck on two limits of angle steel respectively, be fastened on the angle steel with nut, vertical fixing has the pin nail of cross bar shape on the bar on keratotic plug both sides, and the prismatic standpipe is fixed on pin nail end;

Described prismatic standpipe is fixed on pin nail end, is that the one side with prismatic standpipe short-axis direction is fixed with otic placode, and the pommel of otic placode is clipped in the groove of stepping on the yoke plate termination fastening with screw;

The described edge pad that is stuck on two limits of angle steel is to have groove on the one side on the nearly angle steel limit of crossing bolt hole one side on the pad, and the one side of groove is for being attached to the plane outside the angle steel limit, and the another side of groove is and inclined-plane at angle, described plane;

The angle on described plane and inclined-plane is 30 degree;

Describedly link to each other, overlap and hang over the outer anti-falling device of prismatic standpipe major axis opposite side tube wall with people's waistband, be outside the prismatic standpipe long axis direction tube wall in the anti-falling device support body side about, supporting is attached to the directive wheel of long axis direction outer tube wall, supporting is equipped with the cam of bottom band handle ring between the directive wheel in the support body, and the two ends of extension spring are separately fixed at the outer upper end of supporting-point of support body top and cam; In the support body of a relative side with cam, installation can have the pulley yoke of suitable long axis direction swing, and the spring leaf that is fixed in the support body is pressed in the pulley of pulley yoke upper support on the long axis direction outer tube wall of this side; The rope of direct bearing is connected on people's the waistband on the handle ring.

Advantage of the present utility model and good effect are, because the standpipe of described falling proof device is that shaft section is the prismatic standpipe of prismatic, the anti-falling device cover hangs over outside the tube wall of major axis opposite side of prismatic standpipe, the minor axis tube wall of standpipe can be securely fixed in the vertical angle steel side on the electric wire pylon, not overslaugh anti-falling device slides up and down along standing tube outer wall, omitted with the electric wire pylon with high vertical rod, consumable quantity is half of existing circular standpipe, also greatly reduces installation cost and material and transports to on-the-spot cost of transportation.
