The utility model discloses it is rational in infrastructure, simple to operate, big rope from the outside or inside roll -off in the gap of two pulleys of man -like shelf, safe and reliable is played to rise in prevention that can be fine.
Description
Technical field
This utility model relates to a kind of rig man-like shelf auxiliary equipment, is specifically related to a kind of man-like shelf limit pulley ward off rope device.
Background technology
At present, in the process hoisting, transferring derrick, when derrick lifting or after transferring to certain position, big rope meeting gap place between two pulleys of man-like shelf pulley support, if now restricting greatly External Force Acting, restricting it is possible to can skid off from the gap of beam pulley greatly, such derrick has very big danger hoisting, in decentralization process, and increase the labor intensity of staff, add the danger coefficient of workman.
Summary of the invention
The purpose of this utility model is aiming at the defect that prior art exists, it is provided that a kind of rational in infrastructure, easy for installation, it is possible to well prevention big lifting rope inwardly or outwardly skids off from the gap of man-like shelf two pulley, safe and reliable man-like shelf limit pulley ward off rope device.
Its technical scheme is: man-like shelf limit pulley ward off rope device, including the connection seat being fixedly connected on big pulley end lid, the connecting plate of described connection seat is provided with installation screwed hole, described installation screwed hole female thread is connected to gear rope bar, described gear rope bar be arranged in parallel with big pulley end exterior surface, and described gear rope bar free end to truckle direction extend, described gear rope bar be provided with for anti-backstop rope bar with install screwed hole depart from safety pin；
Described ward off rope device also includes for preventing the big block restricted and skid off inside pulley, and described block is correspondingly arranged at the gap place of big pulley and truckle both sides respectively with gear rope bar, and described block is fixed on man-like shelf pulley support.
Described connection seat includes two fixing plates, is linked together by connecting plate between two fixing plates, and described installation screwed hole is arranged on connecting plate.
The end cap of the fixing plate of said two and big pulley welds together.
This utility model is compared with prior art, have the advantage that by increasing man-like shelf ward off rope device, easy for installation, can be good at prevention big lifting rope inwardly or outwardly to skid off from the gap of man-like shelf two pulley, effectively eliminate the potential safety hazard jumped out from pulley groove of restricting greatly in the process of derrick that hoists, transfers, improve safety.

Detailed description of the invention
With reference to Fig. 1-Fig. 3, man-like shelf limit pulley ward off rope device, including the connection seat 2 being fixedly connected on big pulley 1 end cap, the connecting plate 3 of described connection seat 2 is provided with installation screwed hole 4, described installation screwed hole 4 female thread is connected to gear rope bar 5, described gear rope bar 5 be arranged in parallel with big pulley 1 external face, and the described free end keeping off rope bar 5 extends to truckle 6 direction, and described gear rope bar 5 is provided with for anti-backstop rope bar 5 and installs the safety pin 7 that screwed hole 4 departs from；By installing gear rope bar 5 on connecting plate 3, gear rope bar 5 is installed between two pulleys outside the pulley of man-like shelf limit, can effectively prevent big rope from outwards jumping out.
Described ward off rope device also includes for preventing the big block 8 restricted and skid off inside pulley, wherein, block 8 is semicircle block, and described block 8 is correspondingly arranged at the gap place of big pulley 1 and truckle 6 both sides respectively with gear rope bar 5, and described block 8 is fixed on man-like shelf pulley support.Gap, outside between big pulley 1 and truckle 6 can be stopped by block 8, effectively prevent big rope from jumping out from inner side.
Described connection seat 2 includes two fixing plates 21, is linked together by connecting plate 3 between two fixing plates 21, and described installation screwed hole 4 is arranged on connecting plate 3.By this structure, gear rope bar 5 can be made to be arranged on connecting plate 3, consequently facilitating dismounting and installation.
The end cap of the fixing plate 21 of said two and big pulley 1 welds together.Gear rope bar 5 so can be made to be blocked in the outside of two pulleys all the time, it is prevented that the gap between them is jumped out, safe and reliable.
This utility model is by increasing gear rope bar 5 and block 8, not only easy for installation, and can be good at prevention big lifting rope and inwardly or outwardly skid off from the gap of man-like shelf two pulley, effectively eliminate the potential safety hazard jumped out from pulley groove of restricting greatly in the process of derrick that hoists, transfers, improve safety.
This utility model is not limited to above-mentioned embodiment, in the ken that those skilled in the art possess, it is also possible to make a variety of changes under the premise without departing from this utility model objective, and the content after change still falls within protection domain of the present utility model.
