Abstract
The utility model relates to construction site cone tool ejector technical field, specifically discloses a kind of reinforced cone self-unloading instrument.A kind of reinforced cone self-unloading instrument, this self-unloading instrument comprises dismounting nut, claw, connecting screw rod and clamp nut, wherein, dismounting nut lower surface is provided with the claw matched with cone upper groove to be removed, connecting screw rod one end is threaded with clamp nut through after dismounting nut, and the connecting screw rod other end is threaded with cone center screwed hole to be removed.This self-unloading instrument, makes dismounting nut together with cone compact siro spinning technology to be removed, and overcoming existing extracting tool needs a hand-held spanner to fix the deficiency of cone extracting tool on the other hand; Meanwhile, the locking effect of clamp nut, avoids claw and causes the deficiency of skidding and twisting and warping because local pressure is uneven, and improve resistance to overturning, be conducive to convenient construction.
Description
Technical field
The utility model belongs to construction site cone tool ejector technical field, is specifically related to a kind of reinforced cone self-unloading instrument.
Background technology
In construction activity, set up template or fixing feet hand cradle all can use a kind of instrument on body of wall---cone.It is requisite aid in site operation activity, but, because construction needs cone to be often embedded in concrete, or be exposed to outdoor for a long time, in this case make the screw thread of cone be easy to get rusty, be difficult to reclaim fast and effectively cone by existing extracting tool.When the cone quantity that can not normally reclaim is excessive, greatly construction cost will be increased.Existing cone spanner, extend handle at the middle part of spanner, afterbody is removed with nut check frictionally is manual, using this manual spanner to remove, cone is restricted morely wastes time and energy, and use the extracting tool of manufacturer's recommended also to produce little effect to the dismounting of cone, trace it to its cause, one is that the Material Strength of cone demounting instrument is too low; Two is that the design of existing cone demounting tool technique is insufficient, with two diameters is only
the cylinder of 6, as the force transferring part with cone, is difficult to bear the shearing force between dismounting nut and cone, operates in addition often because claw embeds cone draft deficiency or misoperation easily causes claw to be turned round destruction.
Summary of the invention
The purpose of this utility model is to provide a kind of reinforced cone self-unloading instrument, can solve claw in existing cone demounting process and cannot bear shearing force between dismounting nut and cone and cause the impaired destruction of extracting tool, maybe cannot carry out the problems such as cone demounting.
The technical solution of the utility model is as follows: a kind of reinforced cone self-unloading instrument, this self-unloading instrument comprises dismounting nut, claw, connecting screw rod and clamp nut, wherein, dismounting nut lower surface is provided with the claw matched with cone upper groove to be removed, connecting screw rod one end is threaded with clamp nut through after dismounting nut, and the connecting screw rod other end is threaded with cone center screwed hole to be removed.
Described claw is directly fixed on the one-body molded or claw of dismounting nut and dismantles on nut lower surface.
Groove match in the shape of described claw, size and cone to be removed.
Described connecting screw rod, through after dismounting nut central through hole, is threaded with clamp nut by pad.
Described self-unloading instrument adopts the steel of more than Q235 carbon steel intensity to make.
Remarkable result of the present utility model is: one described in the utility model reinforced cone self-unloading instrument, make dismounting nut together with cone compact siro spinning technology to be removed, overcoming existing extracting tool needs a hand-held spanner to fix the deficiency of cone extracting tool on the other hand; Meanwhile, the locking effect of clamp nut, avoids claw and causes the deficiency of skidding and twisting and warping because local pressure is uneven, and improve resistance to overturning, be conducive to convenient construction; In addition, the compact siro spinning technology of dismounting nut and cone to be removed, the power that band movable cone is rotated is provided by the shearing force between claw and cone and the frictional force between dismounting nut and cone, to avoid because shearing force is excessive the damage that claw causes, extend the service life of cone self-unloading instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of reinforced cone self-unloading instrument described in the utility model;
Fig. 2 is the sectional view in a kind of reinforced cone self-unloading instrument described in the utility model use procedure;
In figure: 1, clamp nut; 2, pad; 3, nut is dismantled; 4, claw; 5, connecting screw rod; 6, cone.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, a kind of reinforced cone self-unloading instrument, comprise dismounting nut 3, claw 4, connecting screw rod 5 and clamp nut 1, wherein, dismantle nut 1 lower surface one or be installed with claw 4, the groove match in the shape of claw 4 in the position and claw 4 of dismantling nut 1 lower surface, size and cone 6 to be removed, dismounting nut 3 center has through hole, after the through hole of connecting screw rod 5 upper end through dismounting nut 3 center, be threaded with clamp nut 1 by pad 2; The lower end of connecting screw rod 5 is helicitic texture, and matches with the screwed hole at cone 6 center to be removed; Dismounting nut 3 is connected with cone 6 to be removed by connecting screw rod 5, and is pressed on cone 6 upper surface to be removed by clamp nut 1 by dismounting nut 3; Whole self-unloading instrument adopts the steel of more than Q235 carbon steel intensity to make.
