Abstract

A device for preventing a telegraph pole from tilting comprises three arc-shaped anchor ears which are matched with each other, wherein the arc-shaped anchor ears are connected with each other end to end through bolts and nuts in sequence, so as to form a circle matched with the telegraph pole; a pulling plate is arranged between each two adjacent arc-shaped anchor ears; the bolts between the adjacent arc-shaped anchor ears penetrate the middles of the pulling plates; the lower end of each pulling plate is hinged with a clamp plate seat; and the upper end of the pulling plate is fixedly connected with a pull ring through a bolt and a nut. The device has the advantages that the safety of a constructor can be guaranteed, and the vertical level of the telegraph pole can be trimmed.

Description

Anti-reversing device

Technical field

The utility model relates to a kind of electric pole that is used for and buries the apparatus assembly that prevents down bar that uses underground.

Background technology

In city net and rural power grids overhead wire and transformation process, especially 110KV is dried with line cement is main high-altitude stringing facility, and cement pole must be imbedded underground earlier when the construction of line; Stand on the ground, and then carry out spreading conducting wire and the work of various electric power annex is installed, during this; Because electric pole as yet can run-off the straight during fixed random, even fall the security incident of bar, in upgrading of rural power grids process; Use because of some electric pole warp is long-term, corrode badly broken, foundation is insecure through the rain drop erosion inlet part, and this moment, staff's upper boom was constructed; Electric pole is prone to take place bar, inclination when removing electric wire and backguy; Thereby there is security incident to take place,, therefore needs a kind of device that prevents down bar in order to guarantee the upper boom safety of construction.

Summary of the invention

The utility model provides a kind of anti-reversing device, when purpose is to prevent to bury underground electric pole or climbs up the electric pole constructing operation, prevents that electric pole from toppling over, and guarantees constructor's safety.

The utility model comprises three arc anchor ears that cooperatively interact; Said adjacent two arc anchor ears join end to end and surround the circle that cooperates with electric pole; The initial and end of said adjacent two arc anchor ears connects through bolt, nut respectively; Between said adjacent two arc anchor ears, arm-tie is set respectively; The middle part of said arm-tie is set on the bolt between the said arc anchor ear, is hinged a clamping plate seat respectively in the lower end of said each arm-tie, is fixedly connected draw ring through bolt, nut respectively in the upper end of said each arm-tie.

When the utility model used, three arc anchor ears surrounded the circle that cooperates with electric pole, and railing is vertically arranged; Overtime work is in below, and the arc anchor ear that is combined together is overlapped to electric pole, is lowered to earth anchor at the correct position of electric pole periphery; The nylon backguy is set between earth anchor and draw ring, and nylon backguy two ends are respectively fixed on draw ring and the earth anchor, in the nylon backguy, are provided with and tighten up spanner; Can adjust the elasticity of nylon backguy through tightening up spanner, and draw positive electric pole; When the nylon backguy of three directions was tightened up, the clamping plate seat of arm-tie lower end can inwardly clamp; Simultaneously, the backguy of three directions makes electric pole very stable, just buries underground at electric pole; The situation that earth is soft, or under the unstable situation of the long-term use of electric pole, even the constructor climbs up electric pole; Can occurrence of tilting yet; In sum, this anti-reversing device can guarantee constructor's safety; This device can play the vertically effect of degree of fine setting electric pole simultaneously; This apparatus structure is simple, easy to use, manufactures easily.

The medial surface of the described clamping plate seat of the utility model is arranged to the arcwall face that cooperates with electric pole; The medial surface of clamping plate seat is arranged to arcwall face can make clamping plate seat and electric pole fit fully; What press from both sides is tight, and reliability is stronger, the unstability of having avoided the clamping plate seat to use distortion to bring.

The specific embodiment

Like Fig. 1,2, shown in 3; This anti-reversing device type comprises three arc anchor ears 1 that cooperatively interact; Adjacent two arc anchor ears 1 join end to end and surround the circle that cooperates with electric pole; The initial and end of adjacent two arc anchor ears 1 connects through bolt 6, nut 7 respectively, between adjacent two arc anchor ears 1, arm-tie 2 is set respectively, and the middle part of arm-tie 2 is set on the bolt 6 between the arc anchor ear 1; Be hinged a clamping plate seat 3 respectively in the lower end of each arm-tie 2, be fixedly connected draw ring 4 through bolt, nut respectively in the upper end of each arm-tie 2.The medial surface of clamping plate seat 3 is arranged to the arcwall face 5 that cooperates with electric pole.

Claims

1. anti-reversing device; It is characterized in that comprising three arc anchor ears that cooperatively interact; Said adjacent two arc anchor ears join end to end and surround the circle that cooperates with electric pole; The initial and end of said adjacent two arc anchor ears connects through bolt, nut respectively, between said adjacent two arc anchor ears, arm-tie is set respectively, and the middle part of said arm-tie is set on the bolt between the said arc anchor ear; Be hinged a clamping plate seat respectively in the lower end of said each arm-tie, be fixedly connected draw ring through bolt, nut respectively in the upper end of said each arm-tie.

2. anti-reversing device according to claim 1, the medial surface that it is characterized in that said clamping plate seat are arranged to the arcwall face that cooperates with electric pole.
