Abstract

The utility model provides a corner paying-off pulley, which comprises a base (1), a vertical iron (2), a wire-jumping preventing device (4) and a pulley assembly (3). The wire-jumping preventing device (4) and the pulley assembly (3) are arranged on the vertical iron (2); and the vertical iron (2) is arranged slantways relative to the base (1). According to the corner paying-off pulley, the vertical iron is arranged slantways relative to the base, and an included angle is formed between the pulley arranged on the vertical iron and the base, therefore, the friction generated by a lead and the vertical iron and the wire-blocking phenomena of a joint are avoided, and potential safety hazard possibly caused by the friction of the lead and the wire-blocking phenomena is eliminated.

Description

The corner pulley block
Technical field
The utility model relates to a kind of pulley block, relates to the corner pulley block that uses in overhead transmission line particularly.
Background technology
In the process of distribution line being carried out construction processing such as newly-built, transformation and maintenance, what often run into is the unwrapping wire processing of overhead transmission line, because overhead transmission line is made up of a plurality of strain sections, each strain section is made up of 12-20 basic electric pole again, be subjected to the restriction of landform, building etc., overhead transmission line is straight line always, and the corner (if just adopting the disconnection extension bar greater than 45 degree) that 1-2 angle is not more than 45 degree may appear in each strain section.This angle pole that is not more than 45 degree is called on engineering embraces vertical rod.
In the prior art, in the unwrapping wire process of overhead transmission line, unwrapping wire is handled and is realized by pulley, promptly realize by the straight line pulley block, shown in Fig. 1 a and Fig. 1 b, straight line pulley block of the prior art comprises: base 1, and base is connected on the straight line pole by set bolt; Upright iron 2 is vertically set on the described base 1; Pulley assembly 3 is arranged on an end of the close base of upright iron 2; Prevent bridle wire apparatus 4, be arranged on the upright iron that wherein, pulley assembly 3 comprises pulley 31 and pulley spindle 32, pulley spindle 32 is fixedly connected on an end of the close base of upright iron 2, and this pulley spindle 32 is parallel with base, and base 1 is arranged on the straight line pole abreast with horizontal plane.Lead moves in pulley during unwrapping wire.
But there are the following problems in the unwrapping wire process for straight line pulley block of the prior art.In overhead transmission line payingoff construction process, particularly adopt old tape ew line, lead will be placed in the pulley and move, when running into the vertical rod type of embracing, because the circuit corner causes the joint of lead always to violate card, and lead when moving with the upright friction rail of pulley flanks, cause the increase of unwrapping wire resistance, damage wires is slowed down payingoff speed easily.If joint card line also can cause cross-arm distortion, the phenomenon of falling the bar, staff on the bar is produced injury.
The utility model content
Problem to be solved in the utility model is to overcome the above-mentioned defective that straight line pulley block of the prior art exists.The purpose of this utility model is to provide a kind of corner pulley block, to solve the card line phenomenon that on the corner lead and upright iron produce friction and lead, increases work efficiency, and eliminates safe hidden trouble.
For addressing the above problem, corner pulley block of the present utility model comprises: base; Upright iron; Prevent bridle wire apparatus, be arranged on the upright iron; And pulley assembly, be arranged on the upright iron, wherein, upright iron phase is obliquely installed for base.
Preferably, the corner pulley block also comprises the substrate that is obliquely installed on base, and this upright iron is arranged on the substrate.
Preferably, substrate and base form 30 degree angles.
Preferably, the corner pulley block also comprises the support that is used for supporting substrate that is arranged on the base.
Preferably, pulley assembly comprises pulley and pulley spindle, and pulley spindle is connected on the upright iron and is parallel to substrate.
Preferably, substrate and support can form integral body.
According to corner pulley block of the present utility model, have following beneficial effect:
-lead and upright iron can not produce friction, can improve payingoff speed, prevent the lead damage, have reduced to drag the line pulling force, have reduced working strength, have improved operating efficiency, have eliminated potential safety hazard yet;
-solved the card line problem of joint, therefore, prevent the cross-arm distortion, fallen the generation of phenomenons such as bar, eliminated potential safety hazard simultaneously.
Description of drawings
Accompanying drawing constitutes the part of this specification, and is used for illustrating principle of the present utility model with this specification.Wherein:
Fig. 1 a and Fig. 1 b are the front view and the end views of straight line pulley block of the prior art;
Fig. 2 a and Fig. 2 b are front view and the end views according to the corner pulley block of the utility model preferred embodiment;
Fig. 3 is the partial schematic diagram that has adopted according to the overhead transmission line of the corner pulley block of the utility model preferred embodiment.
Embodiment
Below with reference to accompanying drawings, describe preferred embodiment of the present utility model in detail.
Fig. 2 a and Fig. 2 b are the front views according to the corner pulley block of the utility model preferred embodiment, Fig. 3 is the partial schematic diagram that has adopted according to the overhead transmission line of the corner pulley block of the utility model preferred embodiment, from Fig. 2 a, Fig. 2 b and Fig. 3, as can be seen, comprise according to the corner pulley block of the utility model preferred embodiment: base 1; Upright iron 2 is arranged on the substrate 5 with respect to base 1 inclination, preferably, is 30 degree angles (angle [alpha] shown in Fig. 2 a) between substrate 5 and the base 1; Pulley assembly 3, it comprises pulley 31 and pulley spindle 32, and pulley assembly 3 is connected between the upright iron 2 by pulley spindle 32, and this pulley spindle 32 is basic parallel with substrate 5; Prevent bridle wire apparatus 4, be arranged on the upright iron 2.
Also comprise the support 6 that is used for supporting substrate 5 according to corner pulley block of the present utility model, thereby substrate 5 can be arranged on obliquely on the base 1.Certainly, also can substrate and support is integrally formed, and make upright iron 2 be obliquely installed with respect to base 1 by the integrated member that forms by substrate and support.
Fig. 3 shows the electric pole that is provided with straight line pulley block and corner pulley block.As shown in the figure, because circuit angle β is less than miter angle, and by between straight line pole A and armful vertical rod B, the corner pulley block being set, make lead and pulley sidewall not produce friction, improve payingoff speed, prevent the lead damage, reduce and drag the line pulling force, reduce intensity of workers, increase work efficiency.
When the corner of overhead transmission line is adopted according to corner pulley block of the present utility model, in the unwrapping wire process, because pulley and horizontal plane shape are in an angle (in preferred embodiment of the present utility model, this angle is 30 degree), when this lead is mobile in pulley, lead is difficult for producing friction with upright iron, same because the existence of this angle, the joint of lead also is not easy to block, therefore, can overcome the defective that straight line pulley block of the prior art exists, not only improve operating efficiency, and solved the problem of joint card line, eliminated because of blocking the potential safety hazard that line and lead friction cause.
It below only is preferred embodiment of the present utility model; be not to be used to limit the utility model; for a person skilled in the art; the utility model can have various changes and variation; all any modifications of within spirit of the present utility model and principle scope, being made, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
