According to the invention, a one-way completely-covering lower limiting device is provided for a wind turbine tower lift, and can completely cover a space below the lift; in addition, the lower limiting device disclosed by the invention is simple in structure, and has no conflict with a lower escape door in a vertical space, thereby saving the time and improving the safety.
Description
Technical field
The present invention relates to a kind of lower caging device, particularly relate to a kind of lower caging device of blower fan tower barrel companion ladder.
Background technology
When companion ladder work descend to arrive lower limit or detects the bottom when object blocks is arranged, companion ladder can stop down maneuver automatically.Lower caging device can be controlled the lower limit position of companion ladder operation effectively, and when companion ladder moves downward work, effectively protects the safety of below object and the safe in operation of companion ladder.
Lower caging device in the existing blower fan tower barrel companion ladder mainly contains following two problems:
One, the lower caging device protection face of blower fan tower barrel companion ladder is incomplete, can not cover side space under the companion ladder fully, and potential safety hazard is arranged.
Two, the lower caging device structure too complex of blower fan tower barrel companion ladder, after following emergency exits were opened, lower caging device formed escape and hinders; After opening emergency exits, after needing earlier lower caging device to be removed, just can escape smoothly; Reduce escape time, reduced safety.
Summary of the invention
The technical matters that the present invention will solve is can't cover whole elevator underframe bottom in order to overcome prior art lower limit position device, and the too complicated defective of structure, and a kind of lower caging device of blower fan tower barrel companion ladder is provided.
The present invention solves above-mentioned technical matters through following technical proposals: a kind of lower caging device of blower fan tower barrel companion ladder; Comprise the companion ladder underframe; Its characteristics are; Said lower caging device also comprises crashproof parts and two limit switches of the said companion ladder underframe of all standing below, and the right ends of said crashproof parts for being rotationally connected up and down, and being provided with one respectively in the left and right sides of said crashproof parts and hitting plate respectively and between the right ends of said companion ladder underframe below; Two said limit switches are arranged at the left and right sides of said companion ladder underframe below respectively, make saidly to hit plate and said limit switch links each other.
Preferably, said crashproof parts are to enclose the crashproof parts of the shaped as frame that forms by three crash bars.
Preferably, the below right ends of said companion ladder underframe is affixed a junction spare respectively, said about the end of two crash bars be rotationally connected with cooresponding said link respectively.
Preferably, said link be an angle bar, one jiao the cover or a projection.
Among the present invention, but above-mentioned optimum condition combination in any on the basis that meets this area general knowledge promptly gets each preferred embodiment of the present invention.
Positive progressive effect of the present invention is: the present invention is the lower caging device that blower fan tower companion ladder provides unidirectional all standing type, and it can cover side space under the companion ladder comprehensively.Whole crashproof parts are flexibly movable, and do not have the dead angle, ensured the safety of blower fan tower barrel companion ladder largely.In addition, lower caging device of the present invention is simple in structure, does not have on vertical space with following emergency exits and conflicts.When emergency situation occurs, will descend emergency exits upwards to open after, lower caging device can not become escape and hinder, and need not to remove lower caging device, can directly escape.Both save the time like this, improved safety again.
Description of drawings
Fig. 1 is the structural representation of the lower caging device of blower fan tower barrel companion ladder of the present invention.
Fig. 2 is the lateral plan of the lower caging device of blower fan tower barrel companion ladder of the present invention.
The specific embodiment
Provide preferred embodiment of the present invention below in conjunction with accompanying drawing, to specify technical scheme of the present invention.
As depicted in figs. 1 and 2, the lower caging device of blower fan tower barrel companion ladder of the present invention comprises companion ladder underframe 1, crashproof parts and two limit switches 3 in order to the detecting obstacles thing.Wherein, crashproof parts adopt and enclose the crashproof parts 2 of the shaped as frame that forms by three crash bars in the present embodiment, the length coupling of the length of right crash bar 21 and left crash bar 22 and companion ladder underframe 1, the width coupling of the length of Guard Assy 23 and companion ladder underframe 1.Like this, the crashproof parts 2 of shaped as frame can cover the below of companion ladder underframe 1 comprehensively.
The end of right crash bar 21 and left crash bar 22 is rotationally connected with the right ends of companion ladder underframe 1 below respectively, and right crash bar 21 is rotated up and down with left crash bar 22.Simultaneously, on right crash bar 21, be provided with one and hit plate 23, be provided with one on the left crash bar 22 and hit plate 24.
Two limit switches 3 are arranged at the left and right sides of companion ladder underframe 1 below respectively, make to hit plate 23 and hit plate 24 and link each other with cooresponding limit switch 3.
Preferably, the affixed a junction spare 4 of right ends difference below companion ladder underframe 1, the end of the end of right crash bar 21 and left crash bar 22 is rotationally connected through a turning cylinder with cooresponding link 4 respectively.This structure can effectively prevent the wearing and tearing between left and right sides crash bar and the companion ladder underframe, has improved the degree of being connected firmly between each parts.Link 4 can a preferred angle bar, one jiao of cover or a projection, makes the crashproof parts 2 of whole shaped as frame movable around the axle easy on and off of angle bar, angle cover or projection.
Working process of the present invention is: when the blower fan tower barrel companion ladder normally descended, because action of gravity, the crashproof parts 2 of shaped as frame were in normal hang.At this moment, hit plate 23 and hit plate 24 and do not contact limit switch 3, can not trigger limit switch 3.When the crashproof parts 2 of lower caging device touched the below obstacle, left crash bar 21 and/or right crash bar 22 were oppressed, and a unsettled end moves up.Like this, drive is hit plate 23 and is hit plate 24 and moves up, thereby contact limit switch 3 makes limit switch 3 send danger signal, and the blower fan tower barrel companion ladder is out of service.
When causing danger, the staff in the companion ladder is pulled upwardly emergency exits, and staff directly M/C triggers limit switch 3, makes companion ladder out of service.Like this, the staff can be clog-free smoothly from the escape of companion ladder below.
To sum up, the present invention is simple in structure, can cover the below of companion ladder underframe comprehensively, has removed the obstacle dead angle, has effectively ensured the safety of companion ladder.In addition, whole lower caging device has also made things convenient for staff's installation and debugging.
Though more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only are casehistorys, protection scope of the present invention is limited appended claims.Those skilled in the art can make numerous variations or modification to these embodiments under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
