Abstract
The utility model discloses a ladder leg stabilizer of a square insulating single-leg ladder. The ladder leg stabilizer comprises leveling bolts and a connecting plate, wherein the connecting plate is in a rectangle shape, four corners of the connecting plate are respectively provided with a through hole, one leveling bolt is arranged in each through hole in a sleeving way, and four connecting holes are arranged on the connecting plates; and two nuts are both arranged on each leveling bolt, one of the nuts is positioned below the connecting plate, and the other nut is positioned above the connecting plate. The supporting area of a ladder leg in the utility model is much larger than the area of a ladder leg of the original insulating leg ladder so that the square insulating single-leg ladder has good supporting performance, and the auxiliary staff on the ground can also help to hold the ladder. In addition, the local height of the connecting plate can be adjusted by adjusting the heights of the nuts so that the whole connecting plate achieves a balanced state.
Description
One, technical field: the utility model relates to the employed insulation unipods of a kind of power system maintenance circuit ladder, particularly relates to a kind of firm device of foot of ladder of square insulation unipods ladder.
Two. background technology: along with the continuous expansion of city framework, the running environment of high-tension line is also more and more abominable, at present, the fried stone that cuts into a mountain under the high-tension line gets more and more and the danger that injures lead by a crashing object is all arranged at any time, in addition, big machinery construction under the high-tension line also can cause the lead damage at any time, and this all directly threatens the safe operation of high-tension line.When sectional area of wire damage is serious, the lead safe distance is not enough and wire type hour, the high-tension line of damage can't adopt the method that hangs insulated flexible ladder to keep in repair, and can only adopt the method for insulation unipods ladder to keep in repair.Insulation unipods ladder is to support to erect with ground, and the problem that the unipods ladder that insulate at present exists is: 1, the foot of ladder area is little, and is little with the contact surface on ground, frictional force is little, the auxiliary bad control of electrician in ground.2, under the condition of physical features injustice, the foot of ladder balance of the unipods ladder that can't guarantee to insulate.The problems referred to above are brought potential safety hazard to livewire work, also violate the relevant regulations of " State Grid Corporation of China's electric power safety working regulation " simultaneously.
Three. the utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of simple in structure, cost is lower, contact area is big and the firm device of foot of ladder of square insulation unipods ladder that can leveling.
The technical solution of the utility model is: a kind of firm device of foot of ladder of square insulation unipods ladder, contain leveling bolt and junction plate, described junction plate is a rectangle, its four jiaos places are provided with a through hole respectively, all be set with a described leveling bolt in each described through hole, described junction plate is provided with four connecting holes.
Nut on each described leveling bolt is two, and one of them nut is positioned at the below of described junction plate, and another nut is positioned at the top of described junction plate.
The beneficial effects of the utility model are:
1, the utility model Area of bearing is much larger than the area of original insulation unipods ladder foot of ladder, and its supportive is good, and the ground support staff also can well carry out helping.In addition, adjust the height of nut, can adjust the height of local junction plate, make whole junction plate reach equilibrium state.
2, the utility model is simple in structure, cost is lower, contact area is big and can leveling, and it is applied widely, has good economic benefit after the popularization.
Four. description of drawings:
Fig. 1 is the structural representation of the firm device of foot of ladder of square insulation unipods ladder;
Fig. 2 is the vertical view of the firm device of foot of ladder of square insulation unipods ladder.
Five. the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-leveling bolt, 2-nut, 3-junction plate, 4-connecting hole.
The firm device of foot of ladder of square insulation unipods ladder contains leveling bolt 1 and junction plate 3, and junction plate 3 is a rectangle, and its four jiaos places are provided with a through hole respectively, all are set with a leveling bolt 1 in each through hole, and junction plate 3 is provided with four connecting holes 4.
During use, by connecting bolt and connecting hole 4 junction plate 3 is fixed on the foot of ladder of original insulation unipods ladder, this has increased the contact area of insulation unipods ladder, thereby good stability, adjusting nut 2 can be adjusted the height of local junction plate 3, makes whole junction plate 3 reach equilibrium state.
Claims (2)
1. the firm device of foot of ladder of a square insulation unipods ladder, contain leveling bolt and junction plate, it is characterized in that: described junction plate is a rectangle, its four jiaos places are provided with a through hole respectively, all be set with a described leveling bolt in each described through hole, described junction plate is provided with four connecting holes.
2. the firm device of foot of ladder of square insulation unipods ladder according to claim 1 is characterized in that: the nut on each described leveling bolt is two, and one of them nut is positioned at the below of described junction plate, and another nut is positioned at the top of described junction plate.
