Abstract
The utility model discloses a ladder foot stabilizer for a columnar steel pin-type insulated single-foot ladder, which comprises columnar steel pins and a connecting plate, wherein at least three columnar steel pins are arranged on the connecting plate; the lower end of each columnar steel pin is cone tip-shaped; a thread is formed at the upper end of each columnar steel pin; nuts are screwed on the threads; connection holes are formed on the connecting plate; and each columnar steel pin has two nuts, one nut is positioned below the connecting plate and the other one is positioned above the connecting plate. By adopting the columnar steel pins, the connecting plate can be fixedly inserted on the ground, so as to improve the stability. Besides, the height of the connecting plate is adjusted through the threads and the nuts which are arranged at the upper ends of the columnar steel pins, so that the whole connecting plate is in 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 cylindricality drill rod formula 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.This brings potential safety hazard to livewire work, also violates 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, the firm device of foot of ladder of a kind of simple in structure, easy to use, good stability and cylindricality drill rod formula insulation unipods ladder that can leveling is provided.
The technical solution of the utility model is: a kind of firm device of foot of ladder of cylindricality drill rod formula insulation unipods ladder, contain cylindricality drill rod and junction plate, three described cylindricality drill rods are set on the described junction plate at least, described cylindricality drill rod lower end is an epiconus, the upper end is provided with screw thread, be combined with nut on this screw thread, described junction plate is provided with connecting hole.
Described junction plate is a rectangle, and its four jiaos places are provided with a described cylindricality drill rod respectively.Nut on each described cylindricality drill rod is two, a below that is positioned at described junction plate, and another is positioned at the top of described junction plate.
The beneficial effects of the utility model are:
1, the utility model adopts the cylindricality drill rod, and junction plate is inserted admittedly on the ground, thereby good stability, and in addition, cylindricality drill rod upper end is provided with screw thread and nut, can adjust the height of local junction plate, makes whole junction plate reach equilibrium state.
2, the area of the utility model junction plate is greater than the area of original insulation unipods ladder foot of ladder, thereby the contact area on itself and ground is big, and supportive is good, and the ground support staff also can well carry out helping.
3, simple in structure, easy to use, the good stability of the utility model and can leveling, 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 cylindricality drill rod formula insulation unipods ladder;
Fig. 2 is the vertical view of the firm device of foot of ladder of cylindricality drill rod formula insulation unipods ladder.
Five. the specific embodiment:
Embodiment: referring to Fig. 1 and Fig. 2, among the figure, 1-cylindricality drill rod, 2-nut, 3-junction plate, 4-connecting hole.
The firm device of foot of ladder of cylindricality drill rod formula insulation unipods ladder contains cylindricality drill rod 1 and junction plate 3, three cylindricality drill rods 1 are set at least (among the figure on the junction plate 3, junction plate 3 is a rectangle, its four jiaos places are provided with a cylindricality drill rod 1 respectively, and three cylindricality drill rods 1 can certainly be set, and determine as required), cylindricality drill rod 1 lower end is an epiconus, the upper end is provided with screw thread, is combined with nut 2 on this screw thread, and junction plate 3 is provided with connecting hole 4.Nut 2 on the cylindricality drill rod 1 is two, and a below that is positioned at junction plate 3 plays a supportive role, and the top that another is positioned at junction plate 3 has locking effect.
During use, by 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, and, cylindricality drill rod 1 can make junction plate 3 insert admittedly on the ground, thereby good stability, adjusting nut 2, can adjust the height of local junction plate 3, make whole junction plate 3 reach equilibrium state.
Claims (3)
1. the firm device of foot of ladder of cylindricality drill rod formula insulation unipods ladder, contain cylindricality drill rod and junction plate, it is characterized in that: three described cylindricality drill rods are set on the described junction plate at least, described cylindricality drill rod lower end is an epiconus, the upper end is provided with screw thread, be combined with nut on this screw thread, described junction plate is provided with connecting hole.
