Description
Technical field
The present invention relates to a kind of utensil safeguarding transmission line of electricity, specifically a kind of bracing frame preventing electric pole from toppling over when climbing electric pole.
Background technology
In rural area, transmission line of electricity is all generally the electric pole erection with steel or cementaceous.Transmission line of electricity needs often to safeguard, and electric pole is as erection power line supporter, often needs to climb up electric pole during maintenance line.But electric pole is likely subject to mechanical damage, and there is fracture or breakage, such electric pole intensity is not enough, when attendant steps on bar, once there is the security incident that electric pole is toppled over, cause circuit power-off and injury to personnel, the electric pole of rural area is generally embedded in soil simultaneously, if the damage location of electric pole is positioned at underground, attendant can not find, and electric pole will be made when climbing to topple over.In addition, due to bury electric pole underground field in take soil in a large number, also the depth of burying of phone can be caused to shoal, or electric pole is inherently in the position of the easy soil erosions such as slope, when raining heavily, rainwater can wash away the soil burying electric pole underground, also the electric pole depth of burying can be caused inadequate, and the electric pole that this depth of burying is inadequate, attendant also can not find, electric pole will be made to topple over when climbing.
Summary of the invention
The technical issues that need to address of the present invention are to provide a kind of electric pole bracing frame of toppling over when preventing from climbing electric pole, solve the problem that electric pole topples over and also facilitate line attendant to step on bar.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of electric pole climbing bracing frame, comprise expansion link and the circular arc type anchor ear corresponding with electric pole cylindrical radian, each anchor ear two ends are provided with the connector of band connecting hole and encircle at electric pole circumferentially by bolt I by anchor ear connection, the outside of anchor ear is provided with hinged block, the telescoping tube composition that described expansion link connects together primarily of some joints, often joint telescoping tube is provided with inserted link hole in correspondence with each other, the outer end of the telescoping tube at expansion link two ends is connected with hinge head, and hinge head is hinged in hinged block by bolt II or is hinged on the bolt I of connection anchor ear; On hinge head and hinged block, also correspondence is provided with angle orientation hole, hinged block is at least arranged two angle orientation holes that opposed vertical direction is 45 ° and 30 °, and is fixed the angle on the relative ground of expansion link by latch; At least two expansion links are arranged on electric pole side straight up along electric pole, and the upper end of described expansion link upwards is also connected with the anchor ear encircling electric pole, and expansion link upwards extends rear and in described inserted link hole, inserts step bar; The two ends of described step bar are provided with some step bar locating holes and are limited on expansion link upwards by latch by step bar; Also have at least three expansion links to support to ground downwards, between downward expansion link, be also horizontally arranged with the cross bar being connected and fixed expansion link, described cross bar be also provided with some cross bar locating holes and by latch, cross bar be connected between downward expansion link.
Further improvement of the present invention is: the anchor ear in support frame as described above arranges four, and hold tightly on electric pole by four bolts connections, each anchor ear centre position be provided with hinged block and connect an expansion link, wherein two bolts I connecting anchor ear also connect an expansion link respectively, be connected to expansion link on hinged block to lower support ground, be connected to expansion link on the connecting bolt I of anchor ear along electric pole upwards and connect in the upper end of this expansion link the anchor ear that four are encircled electric pole.
Further improvement of the present invention is: the length that described expansion link often saves telescoping tube is 500mm, all arranges corresponding inserted link hole at the two ends often saving telescoping tube, inserts step bar or cross bar when expansion link extends in inserted link hole.
Owing to have employed technique scheme, the technological progress that the present invention obtains is: the present invention can prevent electric pole from toppling over when climbing electric pole, and facilitates line attendant to step on bar and operation on bar.The circular arc of anchor ear of the present invention is corresponding with the cylindrical radian of electric pole, electric pole can be held tightly when tightening with bolt, then expansion link supports on ground, can play the supporting role to electric pole, prevents the more shallow electric pole of the electric pole of damaged, buried depth from toppling over when climbing operation.
When using of the present invention, according to the diameter of electric pole, the anchor ear of different number can be combined, facilitate different occasions to use.Expansion link of the present invention and the hinged block on anchor ear and/or bolt I connection being connected each anchor ear, and expansion link comprises the telescoping tube that some joints connect together, convenient for collecting and combination, and can extend and shrink, therefore can adapt to the electric pole of differing heights.When the inserted link hole of expansion link is for installing the step bar climbing electric pole, between two expansion links, just constitute a ladder risen along electric pole, convenient climbing.When expansion link is to lower support, connects cross tube in inserted link hole, the effect of firm support can be played.The angle orientation hole that the hinge head of expansion link and hinged block are arranged, can be fixed to certain angle by expansion link, to adapt to ground and the bearing height of different gradient.The anchor ear of the upper end connection of expansion link upwards, can encircle electric pole, play positioning action to the upper end of expansion link.
The bolt I of anchor ear is also used as the hinge of connection expansion link, especially connects upwards as the expansion link of cat ladder, the usage quantity of anchor ear can be reduced.The present invention adopts four expansion links to support to ground, arranges situation on the slope to electric pole, supports more firm.The length that expansion link often saves telescoping tube is 500mm, the step-length of ascending a height of bases fit people, inserts step bar or cross bar, just can use as ladder in the inserted link hole of telescoping tube junction.
