Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Fig. 1 shows a prior art, in which a tension-resistant utility pole needs to be buried and installed on the ground after being positioned. One part of an anchor rod in the fixing device is buried underground, the other part of the anchor rod is arranged on the ground, and workers need to bend the anchor rod at a certain angle at the level of the ground to align the anchor rod to the top direction of the telegraph pole, so that the anchor rod can coaxially fix the stay wire in the later construction. This leads to an unavoidable error problem, namely: the bending angle must be accurate and the direction must be consistent; therefore, workers often adjust the deviation repeatedly in the construction process to enable the deviation to be aligned exactly, and the workload and the working strength are increased. Meanwhile, a galvanized anti-rust layer of the anchor rod is damaged, and the rusted anchor rod needs to be replaced after a period of time, so that great workload and potential safety hazard are brought to the maintenance of the circuit. The UT cable clamp marked 13 in the figure 1 is in the prior art, the UT cable clamp is large in size, and the installation of the insulation protection pipe sleeve is inconvenient.
Referring to fig. 2-6, the present invention provides a technical solution: an adjustable fixing device for an electric stay wire comprises a lower stay wire rod 2 buried underground, wherein an anchor wire disk 12 is a counterweight device with concrete and is fixed with one end of the lower stay wire rod 2 through screw connection, the anchor wire disk 12 is buried underground, and meanwhile the lower stay wire rod 2 is guaranteed to be vertically arranged without being bent. Go up the one end of anchor bar 1 and be equipped with lantern ring 5, the other end of lower anchor bar 2 is equipped with down lantern ring 6, and lower lantern ring 6 cup joints with last lantern ring 5 mutually, sets up through the lantern ring that can the inter activity for steel strand wires angle can be automatic adjustment at any time, need not the manual work carry out the proofreading of deviation, thereby guarantees that it is unanimous with the direction of pulling force, and the angle is unanimous, and can coaxial fixed, avoids the stability influence that the stress of other directions brought the wire pole. One end of the connecting sleeve 3 is provided with an internal thread 7, one end of the upper anchor rod 1 is provided with an external thread, and the external thread is screwed with the internal thread 7. A conical clamping opening 8 is formed in the inner wall of the other end of the connecting sleeve 3, the conical clamping opening 8 is a conical internal control, and a steel strand is inserted into the tensioning taper sleeve 4; the tensioning taper sleeve 4 comprises a line pressing end 9 and a conical deformation end 10, and the conical deformation end 10 is matched with the conical clamping opening 8. The wire pressing end 9 is clamped by using a clamping tool, so that the tensioning taper sleeve 4 is more tightly fixed outside the steel strand, and the external thread at the position of the upper anchor rod 1 is in threaded connection with the internal thread 7 in the connecting sleeve 3. when the tensioning taper sleeve 4 is integrally inserted into the connecting sleeve 3, the connecting sleeve 3 is rotated, the conical deformation end can be pressed into the conical clamping opening 8 through the matching between threads, and the further fixation of the tensioning taper sleeve 4 on the steel strand is ensured.
The outer diameter of the wire pressing end 9 is smaller than the maximum outer diameter of the conical clamping opening 8, and the wire pressing end 9 is clamped by a tool to be tightly attached to the steel strand, so that the wire pressing end 9 is inevitably deformed. The outer diameter of the line pressing end 9 is smaller than that of the conical deformation end 10, so that the situation that the tensioning taper sleeve 4 cannot be inserted into the conical clamping opening 8 can be effectively avoided.
In order to better ensure the clamping effect of the conical deformation end 10 on the inner side steel strand, the inner diameter of the conical clamping opening 8 is gradually reduced from inside to outside, the conical deformation end 10 is conical, an open slot 11 is axially formed in the conical deformation end 10, and the open slot 11 is circumferentially distributed on the conical surface of the conical deformation end 10. When the connecting sleeve 3 is integrally rotated, the conical deformation end 10 is gradually inserted into the conical clamping opening 8, and the conical deformation end 10 deforms, so that the locking of the steel strand is further ensured, and the stability of the steel strand for fixing is ensured. Two are no less than the quantity of open slot 11, and the utility model discloses be equipped with 4, as shown in figure 6.
An insulating protection pipe sleeve is sleeved outside the upper anchor rod 1 and the connecting sleeve 3. Because the upper anchor rod 1 and the lower anchor rod 2 are close to the ground, and the steel strand is connected with a power grid, the possibility of electrification is provided, and the occurrence of electric shock accidents of people and livestock is avoided by sleeving the insulating protection tube sleeve.
The working principle is as follows:
the utility model discloses arrange anchor 12 underground during the use, and make 2 perpendicular to ground of drop bar, the steel strand wires that will connect wire netting overhead line well wire pole insert taut taper sleeve 4, the line ball end 9 of cliping taut taper sleeve 4 through the instrument makes it compress tightly steel strand wires and become integrative, and insert connecting sleeve 3 with its whole, the cyclic annular connection structure who forms is cup jointed mutually with lower lantern ring 6 to the utilization, thereby guarantee to go up anchor 1 and the coaxial unanimity of wire pole steel strand wires angle, also avoid there being the stress of other directions between it, thereby cause the influence to the stability of wire pole. Because the one end inner chamber of adapter sleeve 3 is equipped with internal thread 7, the one end of going up anchor bar 1 is equipped with the external screw thread, through the inter-fitting between the screw thread, make the in-process of rotating adapter sleeve, the whole length of device obtains the adjustment, conical deformation end 10 inserts conical clamping opening 8 gradually simultaneously, conical clamping opening 8 that constantly narrows down makes conical deformation end 10 constantly inwards contract and presss from both sides tight steel strand wires, when guaranteeing to steel strand wires stable fixed when the construction, avoided using the UT fastener just can realize the fixed problem of steel strand wires. Thereby reach the installation and stabilize and save the effect that the part was used.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
