Description
One, technical field: the present invention relates to the insulation unipods ladder that a kind of power system maintenance circuit is used, particularly relate to a kind of ladder leg stabilizer capable of adjusting support area.
Two, background technology: along with the continuous expansion of city framework, the running environment of high-tension line is more and more severe, at present, the fried stone that cuts into a mountain under high-tension line is more and more and has the danger injuring wire by a crashing object at any time, additionally, big machinery construction under high-tension line will also result in wire damage at any time, and this most directly threatens the safe operation of high-tension line.When sectional area of wire damage is serious, wire safe distance is inadequate and wire type is little, the high-tension line of damage cannot use the method hanging insulated flexible ladder to keep in repair, and the method for insulation unipods ladder can only be used to keep in repair.Insulation unipods ladder is erect with ground as support, at present insulation unipods ladder there is the problem that 1, foot of ladder area little, little with the contact surface on ground, frictional force is little, the ground auxiliary bad control of electrician.2, under conditions of physical features injustice, it is impossible to ensure the foot of ladder balance of insulation unipods ladder.
Three, summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that a kind of simple in construction, cost are relatively low, can adjust Area of bearing and the ladder leg stabilizer capable of adjusting support area being connected firmly.
The technical scheme is that a kind of ladder leg stabilizer capable of adjusting support area, containing leveling bolt and connecting plate, described connecting plate is rectangle, a linking arm it is respectively provided with at its corner, form X character form structure, described linking arm is the channel-section steel of opening upwards, described linking arm is set with a telescopic arm, described telescopic arm can move in linking arm, hole, location it is provided with on described telescopic arm and linking arm, run through hole, described location and be provided with bolt, the outer end of each described telescopic arm is respectively provided with a through hole, this through hole is set with a described leveling bolt, four connecting holes it are provided with on described connecting plate.
Being respectively provided with two nuts on each described leveling bolt, one of them nut is positioned at the lower section of described telescopic arm, and another nut is positioned at the top of described telescopic arm.
Described telescopic arm is the channel-section steel that Open Side Down, and the sidewall of described telescopic arm and linking arm arranges hole, described location, at least two, hole, described location, and spaced apart.Described linking arm is connected with described connecting plate by fixing bolt and alignment pin.
The invention has the beneficial effects as follows:
1, the present invention can adjust Area of bearing by telescopic arm, thus supportive is good and steadiness high.It addition, the height of adjusting nut, it is possible to adjust the height of local connecting plate, make whole connecting plate reach poised state.
2, by hole, location and the movable connection of bolt between telescopic arm of the present invention and linking arm, it is possible to dismount and adjust, simple to operate, easy to use.
3, linking arm of the present invention is connected with connecting plate by alignment pin and fixing bolt, accurate positioning, is connected firmly, and can dismount, it is simple to transports and deposits.
4, present configuration is simple, cost is relatively low, can adjust Area of bearing and be connected firmly, and it is applied widely, has good economic benefit after popularization.
Four, accompanying drawing explanation:
Fig. 1 is the structural representation of ladder leg stabilizer capable of adjusting support area；
Fig. 2 is the top view of ladder leg stabilizer capable of adjusting support area.
Five, detailed description of the invention:
Embodiment: see Fig. 1 and Fig. 2, in figure, 1-leveling bolt, 2-nut, 3-telescopic arm, 4-bolt, 5-positions hole, 6-linking arm, 7-connecting plate, 8-connecting hole, and 9-fixes bolt, 10-alignment pin.
Ladder leg stabilizer capable of adjusting support area contains leveling bolt 1 and connecting plate 7, connecting plate 7 is rectangle, it is connected with a linking arm 6 respectively by fixing bolt 9 and alignment pin 10 at its corner, form X character form structure, linking arm 6 is the channel-section steel of opening upwards, linking arm 6 is set with a telescopic arm 3, telescopic arm 3 is the channel-section steel that Open Side Down, telescopic arm 3 can move in linking arm 6, hole 5, location it is provided with on the sidewall of telescopic arm 3 and linking arm 6, at least two, hole 5, location, and it is spaced apart, run through hole 5, location and be provided with bolt 4, the outer end of each telescopic arm 3 is respectively provided with a through hole, this through hole is set with a leveling bolt 1, four connecting holes 8 it are provided with on connecting plate 7.
Nut 2 on each leveling bolt 1 is two, and one of them nut 2 is positioned at the lower section of telescopic arm 3, plays a supportive role, and another nut 2 is positioned at the top of telescopic arm 3, has locking effect.
During use, make connecting plate 7 be fixed on the foot of ladder of original insulation unipods ladder by connecting bolt and connecting hole 8, which increase the contact area of insulation unipods ladder, thus good stability, adjusting nut 2, it is possible to adjust the height of local connecting plate 7, make whole connecting plate 7 reach poised state.As required, can unclamp and extract out bolt 4, telescopic arm 3 is pulled out or inwardly advances, to change Area of bearing, after adjustment, insert and locking positioning bolt 4.
