Abstract
The utility model relates to a head clamp of a concrete-pole cross arm. The head clamp comprises a beveled-edge steel plate, an intermediate steel plate and a right-angled steel plate, wherein the beveled-edge steel plate and the intermediate steel plate are fixedly connected together, the beveled-edge steel plate is provided with working holes, the lower part of a joint between the intermediate steel plate and the beveled-edge steel plate is provided with a bent-back part, and the right-angled steel plate and the intermediate steel plate are movably connected together through a lead screw. According to the utility model, the lower part of a joint between the intermediate steel plate and the beveled-edge steel plate is provided with a bent-back part which is used for clamping angle iron at one side of the head part of a pole-tower cross arm, the lower right-angled edge of the right-angled steel plate is used for clamping angle iron at the other side of the head part of the pole-tower cross arm and is regulated in tightness by a bolt until being firmly clamped at the front end of the head part of the cross arm, a hoisting line is prevented from teetering due to angle conversion, and the stability is enhanced. The tail part of the lead screw is provided with a round hole for connecting a counterweight line and is provided with the counterweight line, so that two sides of the cross arm are stressed uniformly and the cross arm is prevented from distortion. The head clamp is safe, reliable, convenient and rapid and is flexible to operate.
Description
Technical field
The utility model relates to the cement pole cross-arm head jig that uses in a kind of 66KV charged for replacement straight line string.
Background technology
The operation of tradition 66KV charged for replacement straight line string is owing to the transfer of rural power grids circuit, and some heavy used equipments are presented in face of us, and track remodelling has become our recent major tasks.Wherein changing old-fashioned insulator is exactly a sport job wherein.Charged for replacement can improve power supply reliability again.Rural power grids circuit great majority are cement pole, the shaft tower of going up font, the insulator of traditional this type of shaft tower of charged for replacement, and used cross-arm head clamp not only might make cross-arm torsional deformation but also insecure, and hoisting line has angles shifts slightly, the danger that just might come off.So be badly in need of a kind of flexible operation, instrument conveniently.
The utility model content
The technical problem that the utility model will solve provides a kind of cement pole cross-arm head jig, and this jig can carry out the operation of charged for replacement straight line string.
In order to solve the problem that prior art exists, the technical scheme that the utility model adopts is:
Cement pole cross-arm head jig; It is characterized in that including hypotenuse steel plate, middle steel plate and right angle steel plate; Described hypotenuse steel plate and middle steel plate are fixed together; Have working hole on the hypotenuse steel plate, the bottom of the junction of middle steel plate and hypotenuse steel plate is provided with the replication part, and right angle steel plate and middle steel plate are movably connected through the leading screw screw.
The afterbody of described leading screw screw is provided with the circular hole that connects the counterweight rope.
Advantage and effect that the utility model had are:
The utility model cement pole cross-arm head jig is owing to include hypotenuse steel plate, middle steel plate and right angle steel plate; The bottom of the junction of middle steel plate and hypotenuse steel plate is provided with the replication part; Replication partly blocks the angle bar of shaft tower cross-arm head one side, and the following right-angle side of right angle steel plate blocks the angle bar of shaft tower cross-arm head opposite side and regulated near degree by bolt, is stuck in cross-arm head front end up to firmly; Be unlikely to the hoisting line translation-angle and totter raising stability.The afterbody of leading screw screw is provided with the circular hole that connects the counterweight rope, and afterbody installs the counterweight rope additional, makes the cross-arm both sides stressed evenly, is unlikely to make the cross-arm torsional deformation.Safe and reliable, flexible operation, convenient and swift.
Description of drawings
Fig. 1 is the overall structure sketch map of the utility model.
Among the figure: hypotenuse steel plate 1, middle steel plate 2, right angle steel plate 3, working hole 11, replication part 21, leading screw screw 4, circular hole 41; Following right-angle side 31.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail:
As shown in Figure 1; The utility model cement pole cross-arm head jig includes hypotenuse steel plate 1, middle steel plate 2 and right angle steel plate 3; Described hypotenuse steel plate 1 is fixed together with middle steel plate 2, has working hole 11 on the hypotenuse steel plate 1, and working hole 11 is used to hang 2-2 tackle pulley lifting conductor load.Middle steel plate 2 is provided with replication part 21 with the bottom of the junction of hypotenuse steel plate 1, and right angle steel plate 3 is movably connected through leading screw screw 4 with middle steel plate 2.The following right-angle side 31 of right angle steel plate 3 clamps the transferable conductor load in firm rear to shaft tower cross-arm head angle bar with the replication part 21 of middle steel plate 2.
The afterbody of described leading screw screw 4 is provided with the circular hole 41 that connects the counterweight rope, the insulation rope is installed on the circular hole 41 is used for counterweight, and balance shaft tower cross-arm head both sides are stressed evenly, the unlikely cross-arm torsional deformation that makes.
Claims (2)
1. cement pole cross-arm head jig; It is characterized in that including hypotenuse steel plate, middle steel plate and right angle steel plate; Described hypotenuse steel plate and middle steel plate are fixed together; Have working hole on the hypotenuse steel plate, the bottom of the junction of middle steel plate and hypotenuse steel plate is provided with the replication part, and right angle steel plate and middle steel plate are movably connected through the leading screw screw.
