Description

Locking mechanism for keeping off people climbing pyton

The utility model relates to a kind of blocking device of keeping off people climbing pyton, belongs to charged shaft tower or other can not at will climb the attached device that helps of shaft tower.Be particularly useful for charged shaft tower.

At present power department or other department can only mark to the shaft tower of No climbing or the special messenger keeps an eye on does not have mandatory taboo and climbs measure, and accident often causes casualties.Cause the accident of electric shock in order to reduce the people near high-tension line as power department, a certain section that is defined in power plant, electric substation access or circuit centre has two mutual close parallel or cross links, on joint using double circuit line during operation, all need establish special messenger's monitoring, also stipulate to do discrimination flag (as colour code) or take other measure, have a power failure so which bar circuit the staff can correctly distinguish to every circuit.All only tool is indicative in these measures, and does not have mandatory.Therefore, to the staff who lacks a sense of responsibility, the electric shock accidents that mistake is stepped on charged shaft tower taking place still, brings loss with unfortunate for country and family.

The purpose of this utility model is to provide a kind of blocking device of keeping off people climbing pyton, stops by force to climb charged shaft tower and other dangerous shaft tower, saves manpower, prevents the generation of electric shock accidents and other malignant event, further improves the safety management level.

Technical solution of the present utility model is.This climbs the blocking device of shaft tower; by metal shroud ring 1; the fastening bolt 2 of fixing metal shroud ring 1 works a fixing hurdle 3 compositions that stop protective effect with being fixed on metal shroud ring 1 outer wall; its special character is; between fixing hurdle 3, establish one at least and prop up hurdle 5 with the similar activity of its effect; the inner on a movable hurdle 5 is connected by the outer wall of hinge with metal shroud ring 1; the A point of a movable hurdle 5 outer sections is connecting an end of strut 9 in the locking bracing or strutting arrangement 17, and the other end of strut 9 is connected on the pole 10 of being fixed in metal shroud ring 16 outer walls.Pole 10 is positioned on the same horizon with the dead bolt 11 that is fixed on the lock 12 on the same shroud ring 16, and the distance of the two is not more than the thickness of strut 9 contact positions.

Perpendicular fixedly connected and reclinate horizontal bar 7 has been established in the outer end that hurdle 5 is propped up in the described activity of the technical program.The curvature of horizontal bar 7 bendings and the curvature of bar are coincide, and when a movable hurdle 5 is put down, are adjacent to bar, are beneficial to climb.

The described metal shroud ring 1,16 of the technical program can be circle or polygonal, diameter of a circle, what, the concrete shape of length of side retinal rod tower and deciding on polygon limit.Should evenly arrange in a fixing hurdle 3, a movable hurdle 5 on metal shroud ring 1 outer wall, its quantity stops that reaching it is purpose that the people climbs, as 8,10 or 12 etc.The number on movable hurdle 5, with its put down that the back forms step on bar, the tower passage can make the people climb easily and be advisable, general 1 to 2 gets final product.The described locking bracing or strutting arrangement 17 of the technical program is by strut 9, pole 10, and metal shroud ring 16 and cylinder lock 12 are formed.Around the cylinder lock 12 bucker can be arranged, also can not have bucker, but have this cover can prolong the life-span of lock.Establish pin on the metal shroud ring 16 and step on 15, be beneficial to upper and lower shaft tower.It can be iron plate that pin steps on 15, also can be reinforcing bar etc.

Owing on metal shroud ring 1 of the present utility model, be provided with a movable hurdle 5, the lower end on a movable hurdle 5 is provided with locking bracing or strutting arrangement 17, have to stop and climb dangerous shaft tower, save manpower, prevent the generation of electric shock accidents and other malignant event, can allow to climb the characteristics of shaft tower again under certain condition, simple in structure, cost is low, is a kind of desirable apparatus that department such as electric power uses.

The A of Fig. 2-Fig. 1 is to view (being fixed on the bar);

The B of Fig. 3-Fig. 1 is to view (being fixed on the bar);

The C of Fig. 4-Fig. 1 is to view;

The D of Fig. 5-Fig. 1 is to view;

The E of Fig. 6-Fig. 1 is to view;

The partial enlarged drawing of I among Fig. 7-Fig. 1.

Wherein: the fixing hurdle of 1-iron shroud ring, 2-fastening bolt, 3-, 4-connecting axle, the movable hurdle of 5-, 6-horizontal bar, 7-horizontal bar, 8-connecting ring, 9-strut, 10-pole, 11-dead bolt, 12-lock, 13-iron plate, 14-screw, 15-pin are stepped on, 16-iron shroud ring, 17-locking bracing or strutting arrangement.

The utility model is described in further detail below in conjunction with accompanying drawing.The hinge of present embodiment is a connecting axle 4, and metal shroud ring 1,16 is the iron shroud ring, is evenly welding 6 fixing hurdles 3 on the outer wall of iron shroud ring 1 and is propping up hurdle 5 with 2 activities that are connected by connecting axle 4.6 fixing hurdles 3 have all vertically welded two 6, two activities of horizontal bar that play barrier effect and have propped up on the hurdle 5, have all vertically welded a horizontal bar 6 and horizontal bar 7 of a barrier effect.Iron hoop 8 of horizontal bar 6 sides welding on the movable hurdle 5 is so that be inserted in the head end of strut 9.Strut 9 is made for the round steel of φ 12mm, and the hole of φ 10mm is flattened and is drilled with at its two ends.Weld the pole 10 of long 20mm and the iron plate 13 of long 35mm on the outer wall of iron shroud ring 16 from top to bottom successively, the other end of iron plate 13 is with the fixing cylinder lock 12 of screw, and the dead bolt 11 that guarantees cylinder lock 12 is positioned on the same horizon with pole 10, and the gap between the two is less than 3mm, when being in locking states with assurance cylinder lock 12, strut 9 is enclosed within on the pole 10 securely.For protection lock 12, add a bucker in its outside.Pole 10, welding iron plate steps on 15 as pin on the iron shroud ring 16 of iron plate 13 both sides, auger shell hole 14 on the iron shroud ring 16 of iron plate 13 belows, so that the mounting rod number plate, the correctness that bar personnel rod-rising tower is stepped in prompting helps management.Locking bracing or strutting arrangement 17 is by strut 9, pole 10, and lock 12, iron plate 13, iron shroud ring 16 is formed.Be the use that example illustrates this utility model with two mutual close power line bars below.Install one respectively on two bars, iron shroud ring 16 is 2500mm overhead, forms the blocking device of one group of keeping off people climbing pyton.For ease of management and use, here to the blocking device on the same overhead line structures, select the cylinder lock of same specification for use, key is general.When the circuit on certain bar need overhaul, to lock 12 with key opens, dead bolt 11 is retracted in the lock, make strut 9 break away from pole 10 then, then two movable hurdles 5 are rotated down around axle 4, lean against on the electric pole until the horizontal bar on it 7, and at this moment the keeping off people climbing pyton blocking device has been opened the passage of upper boom, the staff can utilize pole-climbing tool and horizontal bar 7, and pin is stepped on 15 upper booms maintenance circuit.After maintenance finishes, with strut 9 two movable hurdles 5 are propped up, a movable hurdle 5 rotates up around axle 4, treats that the two, is inserted in strut 9 in the pole 10 when propping up a hurdle 6 and being positioned at same plane with fixing, then will be locked, and at this moment dead bolt 11 just contacts with the end of pole 10.The person can not step on the bar maintenance more then not have the key, has reached the purpose of forcing keeping off people climbing pyton.
