Abstract
The invention discloses a ladder stand safety protection device on the top of a tower of a wind driven generator. The ladder stand safety protection device is arranged beside the upper part of a ladder stand in the top of the tower of the wind driven generator and is characterized by comprising a protection cage hinged to one of side beams of the ladder stand; the lower part of the protection cage is sealed, and the upper part of the protection cage is open; the protection cage comprises a base frame; a guardrail is arranged on the base frame; an opening is formed in one side of the guardrail; and one side, which is open, of the guardrail is fixed on the side beam of the ladder stand through a hinge. The safety protection device is arranged on the side beam, which is about 2m away from the lower part of a yaw platform, of the ladder stand, so that negligence and inertness of people are overcome, protection measures are forcibly taken when working personnel climb up and down a manhole door of the yaw platform on the top of the tower, and a phenomenon that the working personnel accidentally drop is avoided; and the safety protection device is simple in structure, convenient to mount and use and safe.
Description
[technical field]
The present invention relates to a kind of ladder stand safety protection device on top of tower of wind driven generator.
[background technology]
The main support structure tower cylinder of wind power generating set is usually high more than 60 meters, operated by personnel and safeguard blower fan need bottom tower cylinder along a cylinder ancient piece of jade, round, flat and with a hole in its centre install catladder climb upper and lower tower cylinder, thus turnover tower cylinder top cabin.Because tower cylinder top safeguards that half space (that is: yaw platform) is generally 1.5 meters high apart from the height at tower cylinder top, the catladder top of upper and lower tower cylinder stretches out that this podium level is usual (to be interfered because tower cylinder cat ladder stretches out the too high meeting of platform and the cat ladder entering cabin when yaw rotation) less than 1 meter.Therefore, also fail to step up yaw platform when staff arrives tower cylinder cat ladder top and just need to untie the anti-falling safe rope that hangs over it or safe slide rail just can climb up yaw platform, but now do not climb up yaw platform staff and on cat ladder, untie safety rope due to carelessness and inertia, then can there is the danger of accidentally dropping or slipping and falling, its consequence is hardly imaginable.So, design a safety device and prevent from staff from arriving cat ladder top accidentally dropping when untiing safety rope or slip and can not fall necessary.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of structure simple, easy for installation, safety, ladder stand safety protection device on top of tower of wind driven generator easy to use.
The object of the present invention is achieved like this:
A kind of ladder stand safety protection device on top of tower of wind driven generator, it is located at the side on inner cat ladder top, wind-driven generator tower top, it is characterized in that it comprises the protection cage be hinged on a wherein curb girder of cat ladder, the bottom back cover opened upper end of described protection cage.
A kind of ladder stand safety protection device on top of tower of wind driven generator as above, it is characterized in that described protection cage comprises underframe, described underframe is provided with to protect and blocks, and protects to block side and be provided with opening, and the described side protecting the opening blocked is fixed on cat ladder curb girder by hinges fixing.
A kind of ladder stand safety protection device on top of tower of wind driven generator as above, is characterized in that described underframe and protects to block being formed by connecting by many bars.
A kind of ladder stand safety protection device on top of tower of wind driven generator as above, it is characterized in that another curb girder of described cat ladder is provided with the latch of fixed protection cage, the described opening opposite side blocked that protects is provided with fixed part, and fixed part is provided with and inserts jack for latch.
A kind of ladder stand safety protection device on top of tower of wind driven generator as above, is characterized in that the obstruction baffle plate of a coaxial linkage is installed at described protection cage top hinge place.
The present invention is arranged on the cat ladder curb girder at distance about 2 meters of, yaw platform bottom, overcome carelessness and the inertia of people, mandatory safeguard procedures of taking are finished the work the operation of personnel's upper and lower tower cylinder top yaw platform manhole door, avoiding accidentally drops or slip falls, structure is simple, easy for installation, safety, easy to use.
[accompanying drawing explanation]
Figure l is the structure chart of wind-driven generator tower of the present invention;
Fig. 2 is structural representation of the present invention;
Fig. 3 is structural representation of the present invention;
Fig. 4 is the structural representation of cat ladder of the present invention and safety device.
[detailed description of the invention]
As shown in Figure 1, a kind of ladder stand safety protection device on top of tower of wind driven generator, it is located at the side on inner cat ladder 10 top, wind-driven generator tower 100 top, cat ladder 10 enters into the yaw platform 101 of inside, wind-driven generator tower 100 top for person easy to use, yaw platform 101 is provided with opening 102, opening 102 is provided with protected apron 103, the upper end of cat ladder 10 extend into above yaw platform 101 through opening 102, safety device comprises the protection cage 1 be hinged on a wherein curb girder of cat ladder 10, the bottom back cover opened upper end of described protection cage 1.Described protection cage 1 comprises underframe 11, and described underframe 11 is provided with to protect and blocks 12, protects to block 12 sides and be provided with opening 13, and the described side protecting the opening 13 blocked is fixed on cat ladder curb girder by hinge 14.Described underframe 11 and protect and block 12 and be formed by connecting by many bars 110.
Another curb girder of described cat ladder 10 is provided with the latch 2 of fixed protection cage 1, and opening 13 opposite side that described protecting blocks 12 is provided with fixed part 15, and fixed part 15 is provided with and inserts jack 16 for latch 2.
The obstruction baffle plate 3 of a coaxial linkage is installed at described protection cage 1 top hinge place.
The present invention is arranged on the cat ladder curb girder at distance about 2 meters of, yaw platform bottom, and its keeps off the cat ladder place of passing through personnel, protects that cage is servo-actuated to be shut and open when pulling baffle plate with hand.When staff leans against that tower cylinder is inner upwards to climb about 2 meters of below the yaw platform of tower cylinder top along cat ladder, safety device is in open mode, and personnel can be up by cat ladder continuation herein smoothly.When staff continue up head withstand obstruction baffle plate can not continue upwards time; obstruction baffle plate is pushed aside with hand; simultaneously with the protection cage of baffle plate coaxial linkage servo-actuated shut closed; now staff can plug on pin lock and protect cage; then staff is protected in this protection cage; and then staff can open yaw platform manhole protective cap, unfasten one's seat-belt on wire line hitch or safe slide rail, by yaw platform perforate on platform.On the contrary, when personnel get off from yaw platform, protection cage is in closed condition personnel and fastens one's safety belt and hang up properly steel wire safety buckle, then opens latch and reverses obstruction baffle plate, and now protecting the servo-actuated personnel of opening of cage can descendingly pass through.Therefore, this safety device overcomes carelessness and the inertia of people, and mandatory safeguard procedures of taking are finished the work the operation of personnel's upper and lower tower cylinder top yaw platform manhole door, and avoiding accidentally drops or slip falls.
