Abstract
The utility model discloses a disassembly device for nuts on scaffold steel fasteners. The disassembly device comprises a support frame 5, wherein the upper surface of the support frame 5 is connected with a rotating shaft 3 through a bearing 8; one end of the rotating shaft 3 is connected with an electric motor 1 through a driving belt on a rotating wheel 2, and the other end of the rotating shaft 3 is connected with a rotating sleeve 9 of which the inner hole is orthohexagonal; an alternating current contactor 4 is electrically connected with the electric motor 1 and a power switch 7 respectively; one end, connected with a fixed sleeve 10, of a handle 6 is movably connected with the support frame 5, the inner hole of the fixed sleeve 10 is rectangular, and the position of the fixed sleeve in the handle 6 corresponds to that of the rotating sleeve 9. The electric motor rotates positively and reversely, so that the nuts on the steel fasteners are loosened on threaded rods, and the rotating function is recovered. Compared with manual disassembly process, the labor intensity of operation staff is reduced, and the work efficiency is improved, so that the reusing rate of the scaffold steel fasteners reaches more than 95%, and the construction cost is reduced.
Description
Technical field
The utility model belongs to the realm of building construction, is specifically related to the provision for disengagement of the steel fastener top nut that in architectural engineering, erection type scaffold uses.
Technical background
In architectural engineering, often adopt steel fastener to set up the bracing frame of scaffold as operating personnel's workbench, safety protection frame or template.Steel fastener is by elasticity bolt, two steel pipes that cross one another to be fixed together, and each steel pipe crosspoint needs to be provided with steel fastener, and therefore setting up the scaffold of setting up in building engineering construction needs a large amount of steel fasteners.Due to building engineering construction inclement condition, add lacking a sense of responsibility of some workmen, bad to the maintenance of steel fastener, often occur that the nut of the bolt on steel fastener and screw rod are difficult for because being got rusty by rainwater etch rotating.Though after artificial treatment, be still difficult for rotating, finally cause whole steel fastener discarded, cause very large waste.
Utility model content
The purpose of this utility model is to overcome the deficiency that nut labor intensity of operating staff is large, steel fastener bolt failure rate is high on the dismounting steel fastener that existing job site exists, a kind of simple structure is provided, there is function anti-, forward, easy and simple to handle, reduce operating personnel's labour intensity, reduced steel fastener and can not become flexible the scaffold steel fastener nut remover of discarded spoilage because of nut.
The technical solution of the utility model is summarized as follows:
A kind of scaffold steel fastener nut remover, comprise bracing frame 5, the upper surface of support frame as described above 5 is connected with turning cylinder 3 by bearing 8, one end of turning cylinder 3 is connected with motor 1 by the driving-belt on moving runner 2, the other end of turning cylinder 3 is that orthohexagonal rotational sleeve 9 is connected with endoporus, and A.C. contactor 4 electrically connects with motor 1 and power switch 7 respectively; The one end that is connected with the handle 6 of fixed muffle 10 is flexibly connected with bracing frame 5, and the endoporus of fixed muffle 10 is rectangle, and fixed muffle is corresponding with rotational sleeve 9 in the position of handle 6.
A kind of scaffold steel fastener nut remover of the present utility model, has function anti-, forward.By the forward and reverse rotation of motor, the nut on steel fastener is become flexible on screw rod, recover the function of its rotation.
The utility model, compared with artificial unloading's technique, has reduced operating personnel's labour intensity, has improved operating efficiency, and reusing of scaffold steel fastener reached more than 95%, has saved construction cost.
Brief description of the drawings
Fig. 1 is that this implements novel structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
A kind of scaffold steel fastener nut remover, comprise bracing frame 5, the upper surface of support frame as described above 5 is connected with turning cylinder 3 by bearing 8, one end of turning cylinder 3 is connected with motor 1 by the driving-belt on moving runner 2, the other end of turning cylinder 3 is that orthohexagonal rotational sleeve 9 is connected with endoporus, and A.C. contactor 4 electrically connects with motor 1 and power switch 7 respectively; The one end that is connected with the handle 6 of fixed muffle 10 is flexibly connected with bracing frame 5, and the endoporus of fixed muffle 10 is rectangle, and fixed muffle is corresponding with rotational sleeve 9 in the position of handle 6.
Use a kind of scaffold steel fastener nut remover to scaffold steel fastener nut dismounting process to be: the orthohexagonal endoporus of first scaffold steel fastener top nut end being put into rotational sleeve 9, turning handle 6, rectangle nut on steel fastener is put into the rectangle endoporus of the fixed muffle 10 on handle, by handle, the bolt on steel fastener is compressed again, last Push switch, motor drives the forward and reverse rotation of turning cylinder 3, and nut is rotated on screw rod, reaches detachable effect.
