Technical Field

The invention relates to the field of electrical equipment, in particular to a novel ladder stand structure of an electric steel pipe iron tower.

Background

The electric steel pipe iron tower has the advantages of attractive appearance, small occupied area, high cost performance, short construction period and the like, and is favored by broad users.

In the use of electric power steel pipe tower, electrician need often climb the top of iron tower through the cat ladder and carry out the operation, the cat ladder structure of current electric power steel pipe tower comprises the steel pipe usually and the nail of climbing that is located the steel pipe both sides, in the current structure, only be connected with one at a hookup location of steel pipe and be circular shape nail of climbing rather than looks vertically section, the nail of climbing of both sides is crisscross formula and distributes, the phenomenon of skidding appears easily at high altitude construction personnel climbing in-process in the cat ladder of this kind of structure, certain risk has been brought for high altitude construction personnel, in addition, the cat ladder of this kind of structure is unfavorable for the rest of high altitude construction personnel climbing midway.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides a novel ladder stand structure of an electric steel pipe iron tower, which avoids the occurrence of treading and slipping of overhead operators in the climbing process, can effectively ensure the personal safety of tower-climbing operators and is beneficial to the midway rest stop of the tower-climbing operators.

In order to achieve the purpose, the invention provides a novel ladder structure of an electric steel pipe iron tower, which comprises ladder frame steel pipes and climbing nails, wherein connecting lug plates are welded on the front sides of the upper end and the lower end of each ladder frame steel pipe, a plurality of short sleeves are uniformly and fixedly welded on the ladder frame steel pipes in the longitudinal direction, a pair of climbing nails positioned in the same horizontal plane are welded on each short sleeve, the inner ends of the pair of climbing nails are welded on the outer sides of the short sleeves in an intersecting manner, the outer ends of the pair of climbing nails extend away from each other gradually, and two pairs of climbing nails on the adjacent short sleeves are arranged on the left side and the right side of each ladder frame steel pipe respectively.

Further, in order to reduce the occurrence of the slipping condition, the cross section of the creeping nail is square, and the upper plane of the creeping nail is horizontally arranged.

Further, in order to provide better support and, at the same time, avoid the detrimental effects on the climbing process, the angle between the two climbing pins is 25 ° to 45 °.

Furthermore, in order to be connected with the steel pipe tower body through bolts, connecting holes are formed in the connecting lug plates.

According to the invention, two crawl nails with a certain included angle are arranged at each connecting point on two sides of the ladder frame steel pipe, so that an operator can support the ladder frame steel pipe by two crawl nails at one time when trampling, and the slipping condition can be effectively avoided. In addition, the two climbing nails arranged at a certain included angle can also be beneficial to the rest of tower climbing operators in midway. Every two climb the nail and be connected through short sleeve and ladder frame steel pipe, can avoid damaging the main part of ladder frame steel pipe in welding process to reduce the bearing strength of ladder frame steel pipe. This cat ladder avoids high altitude operator to take place to trample the emergence of skidding phenomenon at the climbing in-process, can effectual assurance climb tower operation personnel's personal safety, and it does benefit to the midway rest of stopping of climbing tower operation personnel moreover.

Detailed Description

The invention will be further explained with reference to the drawings.

As shown in fig. 1-2, a novel electric power steel pipe iron tower cat ladder structure, including ladder frame steel pipe 1 and climbing nail 2, the connection otic placode 4 has all been welded to the front side of the upper end of ladder frame steel pipe 1 and lower extreme, ladder frame steel pipe 1 vertically goes up fixed welding uniformly has a plurality of short sleeves 3, all welds on every short sleeve 3 and has a pair of nail 2 of climbing that is located same horizontal plane, and the inner end of a pair of nail 2 of climbing welds in the outside of short sleeve 3 with crossing, and the outer end of a pair of nail 2 of climbing extends each other far away gradually, and two pairs of nails 2 of climbing on the adjacent short sleeve 3 set up respectively in ladder frame steel pipe 1's left side and right side.

In order to reduce the occurrence of the slipping condition, the cross section of the creeping nail 2 is square, and the upper plane of the creeping nail is horizontally arranged.

In order to provide better support and at the same time avoid an adverse effect on the climbing process, the angle between the two climbing nails 2 is 25 ° to 45 °.

In order to be connected with the steel pipe tower body through bolts, the connecting lug plate 4 is provided with a connecting hole 5.

Every tie point through making every tie point of both sides of ladder frame steel pipe sets up two crawl nails that become certain contained angle, enables the operation personnel once can have two crawl nails to support when trampling to the condition that can effectively avoid skidding appears. In addition, the two climbing nails arranged at a certain included angle can also be beneficial to the rest of tower climbing operators in midway. Every two climb the nail and be connected through short sleeve and ladder frame steel pipe, can avoid damaging the main part of ladder frame steel pipe in welding process to reduce the bearing strength of ladder frame steel pipe. This cat ladder avoids high altitude operator to take place to trample the emergence of skidding phenomenon at the climbing in-process, can effectual assurance climb tower operation personnel's personal safety, and it does benefit to the midway rest of stopping of climbing tower operation personnel moreover.
