Description
Technical field
The utility model discloses a kind of steel tube scaffold clasp screw maintenance unit, belong to the scaffold clasp technical field.
Background technology
The used scaffold great majority in building site are fastener-style steel pipe scaffolding now.The scaffolding steel pipe fastener has right-angle coupler, rotary buckle and to three kinds of clasps.Fastener mainly by fastened by screw, in case the screw corrosion, just can not use again by fastener.Mostly embracing on the screw after existing fastener is finished has for the first time expired sand-lime, has much all got rusty in addition, and some stripped threads can't rotate, and cleaning is got up difficult especially.Each building site needs a large amount of fasteners, and is downright bad with regard to some after one time engineering is finished, about 6 yuan of fastener market prices, and cost is too high.In addition, the fastener that can't rotate that has, the workman if bad taken, delays high-level activity duration of workman and quality in work high above the ground.
Summary of the invention
For addressing the above problem, the utility model provides a kind of steel tube scaffold clasp screw, uses this maintaining apparatus can easily with the screw reparation, normally use at the construction field (site).
The utility model is realized with following technical scheme: a kind of steel tube scaffold clasp screw maintenance unit, and it comprises being used for fixing is repaiied the screw unit head, is used for the die head threading machine of fixing bolt die and for the cutter bolt die of rethreading;
Described unit head comprises chuck, be installed in the jaw on the chuck and the motor of power is provided to chuck; The output of motor drive shaft is connected transferring power by gear drive with the axle of chuck;
Described die head threading machine comprises bolt die cover fixed axis, is used for fixedly casing, guide rail and the bolt die cover of bolt die cover fixed axis; Described casing is installed on the guide rail and can moves along guide rail; Be equipped with for the operation casing at the mobile operating grip of guide rail at casing;
Described bolt die is installed on the bolt die cover fixed axis by the bolt die cover;
Described bolt die cover fixed axis, chuck, bolt die three's central lines.
The beneficial effects of the utility model are: simple in structure, make easily, and can at the construction field (site) easily with the screw reparation, reduce the use cost of unit in charge of construction.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1-fastener screw; The 2-bolt die; 3.1-jaw; 3.2-chuck; 3.3-driven gear; 3.4-driving gear; 3.5-motor; 4.1 jaw fixed axis; 4.2-casing; 4.3-operating grip; 4.4-guide rail; 4.5-bolt die cover.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, steel tube scaffold clasp screw maintenance unit it comprise and be used for fixing the unit head of being repaiied screw, be used for the die head threading machine of fixing bolt die and for the cutter bolt die 2 of rethreading.Unit head comprises chuck 3.2, be installed in the jaw 3.1 on the chuck 3.2 and the motor 3.5 of power is provided to chuck 3.2; The output of motor 3.5 axles is connected by the axle of gear drive with chuck 3.2.Gear drive is comprised of driving gear 3.4 and the driven gear 3.3 that is meshed with driving gear 3.4; Driving gear 3.4 reaches the purpose of deceleration less than driven gear 3.3.Die head threading machine comprises bolt die cover fixed axis 4.1, is used for fixedly casing 4.2, guide rail 4.4 and the bolt die cover 4.5 of bolt die cover fixed axis 4.1; Described casing 4.2 is installed on the guide rail 4.4 and can moves along guide rail 4.4; The operating grip 4.3 that moves at guide rail 4.4 for operation casing 4.2 is installed at casing 4.2; Bolt die 2 is installed on the bolt die cover fixed axis 4.1 by bolt die cover 4.5; Bolt die cover fixed axis 4.1, chuck 3.2, bolt die 2 threes' central lines.
The present embodiment: whole parts of unit head comprise that jaw 3.1 and chuck 3.2, driven gear 3.3, driving gear 3.4 all adopt the parts on the engine lathe; For economizing on the use of funds, can adopt the parts of scrapping lathe.
Bolt die 2 is cutters of rethreading, selects bolt die according to different screw diameters from different pitch; 60 millimeters of bolt die cover fixed axis 4.1 external diameters, the hollow shaft that internal diameter is 30 millimeters is made by the Q235 steel; Bolt die cover fixed axis 4.1 must overlap with bolt die 2 center lines, screw center line three to be repaired.
Casing 4.2 is that fixedly bolt die overlaps fixed axis 4.1 usefulness, is made by steel; Casing 4.2 is bearing on the guide rail 4.4, realizes that by operating operation handle 4.3 casing 4.2 is mobile at guide rail 4.4 easily.Guide rail is the metal track that is parallel to the unit head axis.
Concrete using method is: fastener screw to be repaired 1 usefulness jaw 3.1 is fixing, bolt die 2 and the screw thread of fastener screw 1 are adjusted to adaptive state, hotwire 3.5, chuck 3.2 drives fastener screw 1 slow circumvolve, the dirts such as corrosion on the fastener screw 1 are just machined away by bolt die 2, reach the purpose of cleaning screw.
