Description

A kind of transmission line pole tower ascent aid
Technical field
The utility model relates to cat ladder field, refers in particular to a kind of transmission line pole tower ascent aid.
background technology
In recent years, due to urban construction high speed development, power load increased sharply, and supply network can not meet the needs of power load development, newly-built high pressure certainly will be wanted to go down town circuit, carry out capacity-increasing transformation to netting twine road, original city.Traditional steel tower, floor space is large, and moulding is inharmonious with contemporary urban environment again, adopts high-tension cable to involve great expense.Adopt the taper shape steel tube bar of annular or polygonal cross-section, structure is simple, stressed clear, processing and manufacturing is easy, and easy construction is safe and reliable to operation, maintenance workload is few, and in view of the advantage that steel pipe pole is so many, current steel pipe pole is commonly used in Construction of Intercity Network.Towering steel pipe pole can be seen everywhere near road side, community.
The fixing cat ladder distance to the ground that steel pipe pole uses is general equal all not to the utmost, the height overhead had is often all very high, even reach 2 meters, this climbs with regard to inconvenience very concerning we operation maintainer, most operating personnel is just held up by others or by interim frame that bamboo is terraced to climb can get at cat ladder, just add the danger of operation so virtually, greatly reduce job safety, so although the fixing too high shaft tower of can protecting of cat ladder avoids non-operating personnel to climb, but also bring very large inconvenience to operating personnel, expand the hazards in operation process simultaneously, time the fixing cat ladder had is installed, distance to the ground is very near, ordinary people stretches out one's hand just can get at cat ladder, like this operation maintainer is facilitated, also reduce the danger that operating personnel in maintenance process climbs cat ladder, but consider that steel pipe pole is all generally be erected at the place that residential block or highway both sides personnel relatively concentrate, although shaft tower is linked with the warning mark of No climbing, but somebody can climb charged shaft tower because of various reasons, so non-operating personnel sometimes will be caused to climb the phenomenon of shaft tower, certain hidden danger is brought to electric power netting safe running.
Therefore, the present inventor makes further research this, and develop a kind of transmission line pole tower ascent aid, this case produces thus.
utility model content
The purpose of this utility model is to provide a kind of transmission line pole tower ascent aid, ensure that the safety of the person and equipment.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of transmission line pole tower ascent aid, comprise extension ladder, mobile jib, fixed hook and adjustable hook, the length of described extension ladder can free adjustment, described mobile jib is fixed on extension ladder, described fixed hook is fixed on mobile jib top, and adjustable hook can slide relative to mobile jib and can be fixed on the optional position on mobile jib.
Further, described fixed hook and adjustable hook all comprise chute, and described chute arranged outside has coupler body, and described chute offers bolt hole.
Further, described extension ladder is connected by anchor ear with between mobile jib.
After adopting such scheme, the utility model compared with prior art, has the following advantages:
1, easy to carry, detachable, is convenient to keeping, lightweight, applied widely;
2, reduce the length of fixing cat ladder, the production cost of cat ladder can be reduced;
3, fix cat ladder with shaft tower to be connected firmly, ensure the safety that operating personnel climbs in operation process also can prevent non-operating personnel from will climbing shaft tower, bring potential safety hazard to the person and equipment;
4, adjustable hook can free adjustment, is applicable to the cat ladder of differing heights pin nail.
accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the schematic diagram of mobile jib;
Fig. 3 is the schematic diagram of hook (fixed hook, adjustable hook);
Label declaration
Extension ladder 1, mobile jib 2, fixed hook 3, adjustable hook 4, anchor ear 5.
embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As shown in the figure, a kind of transmission line pole tower ascent aid that the utility model discloses, comprise extension ladder 1, mobile jib 2, fixed hook 3, adjustable hook 4, wherein extension ladder 1 is connected by anchor ear 5 with mobile jib 2: extension ladder 1 is connected and fixed by Cross Recess Head Screw and anchor ear 5, and mobile jib 2 and anchor ear 5 are bolted fixing.
Adjustable hook 4 freely up and down can regulate along mobile jib 2, is fixed by clamping screw, and fixed hook 3 is connected and fixed by interior hexagonal cone end holding screw, fluting cone end holding screw and mobile jib 2 end.
During use, first the utility model extension ladder 1 and mobile jib 2 are coupled together and fix, fixed hook 3 is first hung on shaft tower and fixes above cat ladder mobile jib 2 and follow closely junction with pin, then adjustable hook 4 is moved, the distance made it between fixed hook 3 equal fixing cat ladder pin follow closely between a span, adjustable hook 4 is hung on shaft tower to fix below cat ladder mobile jib 2 and follow closely junction with pin, and tighten clamping screw and make it fixing, finally check and be connected between cat ladder assistor with fixing cat ladder, confirm that connection can regulate extension ladder 1 to facilitate climbing rearward.
After use terminates, first unscrew clamping screw, adjustable hook 4 can be moved up and down along mobile jib 2, take out adjustable hook 4 and fixed hook 3, extension ladder 1 is disassembled classification keeping from mobile jib 2.
Above are only specific embodiment of the utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design the utility model to be carried out to unsubstantiality, all should belong to the behavior of invading the utility model protection range.
