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 wind-driven generator tower top cat ladder safety device.
[background technology]
The main support structural tower cylinder of wind power generating set is usually high more than 60 meters, staff's operation and safeguard up and down tower cylinder of catladder climbing that blower fan need to be from tower cylinder bottom installs along a cylinder ancient piece of jade, round, flat and with a hole in its centre, thereby the cabin at turnover tower cylinder top.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, 1 meter of the common less than of this podium level (interfering when driftage is rotated with the cat ladder that enters the cabin because tower cylinder cat ladder stretches out the too high meeting of platform) is stretched out at the catladder top of tower cylinder up and down.Therefore, also failing to step up yaw platform when the staff arrives tower cylinder cat ladder top just need to untie the anti-falling safe rope or the safe slide rail that hang over it and just can climb up yaw platform, the yaw platform staff has untied safety rope on cat ladder because carelessness and inertia but do not climb up this moment, then can have the danger of accidentally dropping or slipping and falling, its consequence is hardly imaginable.So, design a safety device and prevent that the staff from arriving the cat ladder top and accidentally dropping or slip and can not fall necessary when untiing safety rope.
[summary of the invention]
The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of simple in structure, easy for installation, safety, wind-driven generator tower top cat ladder safety device easy to use.
The object of the present invention is achieved like this:
A kind of wind-driven generator tower top cat ladder safety device, it is located at the next door on inner cat ladder top, wind-driven generator tower top, it is characterized in that it comprises the protection cage on the wherein curb girder that is hinged on cat ladder, the bottom back cover opened upper end of described protection cage.
Aforesaid a kind of wind-driven generator tower top cat ladder safety device, it is characterized in that described protection cage comprises underframe, described underframe is provided with to protect and blocks, and protects to block a side and be provided with opening, and a described side of protecting the opening that blocks fixes on the cat ladder curb girder by hinges fixing.
Aforesaid a kind of wind-driven generator tower top cat ladder safety device is characterized in that described underframe and protects to block by many bars being formed by connecting.
Aforesaid a kind of wind-driven generator tower top cat ladder safety device, 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 that blocks that protects is provided with fixed part, and fixed part is provided with for latch and inserts jack.
Aforesaid a kind of wind-driven generator tower top cat ladder safety device is characterized in that hinge place, described protection cage top installs the obstruction baffle plate of a coaxial linkage.
The present invention is installed on the cat ladder curb girder apart from about 2 meters, yaw platform bottom, people's carelessness and inertia have been overcome, mandatoryly take the safeguard procedures up and down operation of tower cylinder top yaw platform manhole door of personnel of finishing the work, avoid accidentally dropping or slipping and fall, simple in structure, easy for installation, safety, easy to use.

[specific embodiment]
As shown in Figure 1, a kind of wind-driven generator tower top cat ladder safety device, it is located at the next door on inner cat ladder 10 tops, wind-driven generator tower 100 tops, cat ladder 10 is used for making things convenient for the user to enter into the yaw platform 101 of inside, wind-driven generator tower 100 top, yaw platform 101 is provided with opening 102, opening 102 is provided with protected apron 103, the upper end of cat ladder 10 is passed opening 102 and is extend into above the yaw platform 101, safety device comprises the protection cage 1 on the wherein curb girder that is hinged on 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 1 sides and be provided with opening 13, and a described side of protecting the opening 13 that blocks is fixed on the cat ladder curb girder by hinge 14.Described underframe 11 and protecting blocks 12 and is 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 described protecting blocked 12 opening 13 opposite sides and be provided with fixed part 15, and fixed part 15 is provided with for latch 2 and inserts jacks 16.
The obstruction baffle plate 3 of a coaxial linkage is installed at hinge place, described protection cage 1 top.
The present invention is installed on the cat ladder curb girder apart from about 2 meters, yaw platform bottom, and it keeps off at the cat ladder place that personnel pass through, and cage is servo-actuated shuts and open in protection when pulling baffle plate with hand.When the staff leaned against tower cylinder inside and upwards climbs to the yaw platform of tower cylinder top below about 2 meters along cat ladder, safety device was in open mode, and personnel can be up by cat ladder continuation herein smoothly.When the staff continues up head and withstands the obstruction baffle plate and can not continue upwards; push the obstruction baffle plate aside with hand; simultaneously with the servo-actuated closure of shutting of the protection cage of baffle plate coaxial linkage; the staff can plug and protect cage on the pin lock this moment; then the staff is protected in this protection cage; and then the staff can open the yaw platform manhole protective cap, wire line hitch or safe slide rail on unfastening one's seat-belt, by in the yaw platform perforate to platform.On the contrary, when personnel got off from yaw platform, the protection cage was in the closed condition personnel and fastens one's safety belt and hang up properly steel wire safety buckle, then opens latch and reverses the obstruction baffle plate, and protect the servo-actuated personnel of opening of cage and can descendingly pass through this moment.Therefore, this safety device has overcome people's carelessness and inertia, mandatoryly takes the safeguard procedures up and down operation of tower cylinder top yaw platform manhole door of personnel of finishing the work, and avoids accidentally dropping or slipping and fall.
