Abstract
The invention discloses a brake clip for replacing a groundwire on a high-tension line without stopping electricity, which belongs to the field of electromechanical technology, and relates to a tooling used for replacing the groundwire of a high-altitude high-voltage power supply circuit during running in particular. The technical scheme is mainly characterized in that: a fixed friction clamping strip (6), a clamping block (7) capable of swinging, and a pull rod (73) are arranged in an empty cavity formed between an upper rectangle plate (3) and a lower rectangle plate (4) arranged in parallel; the other end of the pull rod (73) stretches out; moreover, a protective sleeve (74) is arranged at the head part of the pull rod; when the downwards concave flexivity of a groundwire (79) exceeds a certain number, then the clamping block (7) swings to clamp the groundwire (79) to lead the groundwire (79) to be incapable of contacting with a high-tension line running a lower position; in this way, the effects of safe and reliable use can be realized; therefore, replacing operation can be implemented without stopping electricity, and industrial and agricultural production are not influenced. The brake clip for replacing the groundwire on the high-tension line without stopping electricity has simple structure.
Description
Technical field
The invention belongs to the mechanical ﹠ electrical technology field, specifically relate to the frock that a kind of ground wire to high aloft in service supply line is changed use.
Background technology
At present, to the method that the once visited place line of operating high aloft supply line is changed, must be first power failure, remove the once visited place line and set up new ground wire, the state that resumes operation then simultaneously.Yet, though this tradition replacing method is simple and convenient, the one side of its deficiency being arranged, its weak point is: industrial and agricultural production is grown, had a strong impact on to interruption duration.
Summary of the invention
Task of the present invention provides a kind of the power failure and changes the brake folder that ground wire is used on high-tension line.And, safe in utilization, reliable; Simple in structure.
Technical scheme of the present invention is as follows:
A kind of the power failure on high-tension line changed the brake folder that ground wire is used, it is made of the upper and lower rectangular slab 3,4 that be arranged in parallel, distance between its upper and lower rectangular slab 3,4 connects fixing by the pin 8 at the front end place that is positioned at upper and lower rectangular slab and the pin 5 of rear end, be provided with fixing friction grip bar 6, the clamp 7 that can swing and pull bar 73 in the cavity that constitutes between upper and lower rectangular slab 3,4, its friction grip bar 6 is fixed between the pin 5,8 and near the inboard of pin 8; Its clamp 7 between pin 5,8, the positioning end 76 of its clamp 7 is positioned at the inboard of middle section, the rear end pin 5 of upper and lower rectangular slab, and connects with bearing pin 77 and upper and lower rectangular slab 3,4; The swinging end 71 of its clamp 7 be provided with the friction grip piece 75 of circular shape with friction grip bar 6 facing surfaces; Its pull bar 73 is positioned at the inboard of pin 5 on the right side, rear end of upper and lower rectangular slab, and its pull bar 73 positioning ends connect with bearing pin 78 and upper and lower rectangular slab 3,4, and its pull bar 73 other ends stretch out the right side of upper and lower rectangular slab and are provided with sheath 74 at its head; Its pull bar 73 and 72 connections of clamp 7 usefulness follow-up connecting rods, and when making the central lines of the axis hole center line of its sheath 74 and ground wire 79, the distance between the relative working surface of friction grip piece 75 and friction grip bar 6 is greater than the diameter of ground wire 79; When the amount of deflection of the center line of the ground wire 79 that stretches out in the axis hole of sheath 74 did not overlap with the amount of deflection of the center line of the ground wire 79 of run duration and surpasses a set point, the distance between the relative working surface of its friction grip piece 75 and friction grip bar 6 was less than the diameter of ground wire 79.
And the relative working surface of friction grip piece 75, friction grip bar 6 is provided with the clamping slot that matches with ground wire 79 diameters.
Its sheath 74 is the involutory structure of two semi-circular shapes.
During use, be separately positioned on the ground wire of two adjacent iron tower ends by two identical in structure brake folders 1,2, that is: open last rectangular slab 3 and sheath 74 on the brake folder 1,2, and with in ground wire 79 card entry slots with the hole in, simultaneously, brake folder 1,2 is respectively fixed on two adjacent iron tower ends.Its process of the once visited place line being replaced by new ground wire that does not have a power failure is: the follower head 79A of once visited place line and the front end of new ground wire are coupled as one, and the front end 79B of traction once visited place line makes its new ground wire enter the once visited place line position, replaces the once visited place line, reaches the replacing purpose.In the replacing process, if the ground wire between the brake folder 1,2 is recessed, will cause sheath 74 to move down, follow-up connecting rod 72 drive clamps 7 are swung to sheath 74 places one side direction simultaneously.After the recessed amount of deflection of ground wire between the brake folder 1,2 surpasses certain numerical value, then driving sheath 74 moves down also above after the certain numerical value, then clamp 7 swings clamp ground wire 79, its ground wire 79 can not be touched with the operating high-tension bus-bar of lower position, just can reach safety, the effect of using reliably; The replacing operation that just can not have a power failure does not influence industrial and agricultural production.It is simple in structure.
Beneficial effect of the present invention is as follows: owing to adopt technique scheme, realized not having a power failure and changed ground wire operation and safe and reliable result of use, and do not influenced industrial and agricultural production.It is simple in structure.

Fig. 2 is the A-A view among Fig. 1
The invention will be further described below in conjunction with embodiment for embodiment
Embodiment 1
Fig. 1, embodiment illustrated in fig. 2 in, a kind of the power failure on high-tension line changed the brake folder that ground wire is used.It presss from both sides the use that combines by 1 brake identical with 2 two.1 and 2 structures are identical.
Its sheath 74 is the involutory structure of two semi-circular shapes.
During use, be separately positioned on the ground wire of two adjacent iron tower ends by two identical in structure brake folders 1,2, that is: open last rectangular slab 3 and sheath 74 on the brake folder 1,2, and with in ground wire 79 card entry slots with the hole in, simultaneously, brake folder 1,2 is respectively fixed on two adjacent iron tower ends.The follower head 79A of once visited place line and the front end of new ground wire are coupled as one, and the front end 79B of traction once visited place line makes its new ground wire enter the once visited place line position, replaces the once visited place line, reaches the replacing purpose.In the replacing process, if the ground wire between the brake folder 1,2 is recessed, will cause sheath 74 to move down, follow-up connecting rod 72 drive clamps 7 are swung to sheath 74 places one side direction simultaneously.After the recessed amount of deflection of ground wire between the brake folder 1,2 surpasses certain numerical value, then driving sheath 74 moves down also above after the certain numerical value, then clamp 7 swings clamp ground wire 79, its ground wire 79 can not be touched with the operating high-tension bus-bar of lower position, just can reach safety, the effect of using reliably; The replacing operation that just can not have a power failure does not influence industrial and agricultural production.It is simple in structure.
