It should be noted that the features in the following embodiments and examples may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without inventive step, are intended to be within the scope of the present disclosure.
Example one
As shown in fig. 1-5, on the one hand, the embodiment provides a quick dismounting device for a foot nail of a power transmission line iron tower, which comprises a ratchet wrench and a clamp main body; the clamp main body comprises a swing arm, a connecting rod and an adjustable clamping screw rod; swing arms are respectively arranged at two ends of the connecting rod, one end of one swing arm is hinged with one end of the connecting rod, and the other end of the swing arm is provided with a foot nail nut limiting sleeve; one end of the other swing arm is hinged with the other end of the connecting rod, the other end of the other swing arm is provided with a nut limiting seat, and the nut limiting seat is movably connected with the swing arm; one end of the nut limiting seat is connected with the ratchet wrench; the middle part of swing arm is equipped with the spout, the spout is passed respectively to the one end of adjustable clamping screw, and the one end of adjustable clamping screw is equipped with the kelly, and the other end is equipped with adjusting nut.
It should be noted that the clamping rod adopts the tail end of the adjustable clamping screw to penetrate through the clamping rod, the clamping rod can effectively clamp one side of one swing arm, and the clamping rod is matched with the adjusting nut to clamp the other swing arm to form a clamping state.
The foot nail nut limiting sleeve and the swing arm are connected in a fixed connection or a buckling connection mode; the limit of the foot nail nut can be ensured;
the connection mode of the nut limiting seat and the swing arm is swing joint, rotation can be achieved, balls or lubricating agents can be added into the nut limiting seat and the swing arm, rotation friction is reduced, manpower consumption is reduced, models of different sizes can be replaced by the nut limiting seat and the foot nail nut limiting sleeve, and the foot nail limiting sleeve is used for foot nails of different models.
On the other hand, the invention relates to a use method of a quick dismounting device for a foot nail of a power transmission line iron tower, which comprises the following steps: s1: loosening the adjusting nut and expanding the two swing arms; s2: after the foot nails penetrate through the angle steel, the foot nails are preliminarily fixed by foot nail nuts; s3: the foot nail nut limiting sleeve is sleeved into the foot nail nut after passing through the foot nail, then the nut limiting seat is sleeved into the foot nail nut, the adjusting nut is screwed to enable the two swing arms to contract the clamping angle steel, and finally the foot nail nut limiting sleeve and the nut limiting seat are respectively tightly attached to the foot nail nut and the foot nail nut; s4: at the moment, an operator can liberate both hands, connect the output end of the ratchet wrench with the nut limiting seat, swing the ratchet wrench in a reciprocating manner, keep the foot nail nut still, rotate and clamp the foot nail until the foot nail completely clamps the angle steel, and loosen the adjusting nut taking-out device after the operation is finished; if the ratchet wrench needs to be disassembled, the direction adjusting button on the ratchet wrench only needs to be pulled reversely, and then the ratchet wrench is swung in a reciprocating mode.
Example two
The difference from the first embodiment is that: the end of the swing arm far away from the hinge joint is bent inwards in a Z shape. It should be noted that the purpose that adopts the Z type to inwards buckle is improved nut stop collar and nut spacing seat and is followed closely degree with foot nail nut and foot nail nut respectively for sufficient space is left to the bottom of swing arm, prevents that the bottom centre gripping from to the angle steel, leading to the assembly difficulty. Simultaneously, the nut limiting sleeve and the nut limiting seat can be respectively sleeved in the foot nail nut and the foot nail nut in parallel by matching with the adjustment of the telescopic rod, so that the phenomenon that the nut limiting seat is inclined and the clamping position is twisted in the twisting process is effectively avoided.
The foot nail nut limiting sleeve is connected with one end of the swing arm through a buckle.
The purpose of the buckle connection is to limit the foot nail nut by sleeving the swing arm into the foot nail nut limiting sleeve, so that the foot nail nut is prevented from being twisted in the rotation process, and the foot nail is prevented from being screwed or unscrewed to lose efficacy; simultaneously when the installation, when foot nail nut stop collar was packed into the foot nail nut, can rotate the fine setting to the position of foot nail nut stop collar for the outer hexagonal position of the interior hexagonal of foot nail nut stop collar and foot nail nut is unanimous, can install foot nail nut stop collar fast under the swing arm condition of not swinging, improves the installation effectiveness.
The connecting rod adopts a telescopic rod; the telescopic link is equipped with spacing buckle. It should be noted that, spacing buckle also can replace with adjusting bolt, adjusts the length of telescopic link through screwing or loosening adjusting bolt for the installation conveniently adjusts the degree of sticking to that improves nail nut stop collar and nut spacing seat respectively with foot nail nut and foot nail nut, and the installation effectiveness is high.
The method of using the present embodiment is the same as the first embodiment.
EXAMPLE III
The difference from the second embodiment is that: and a ratchet wrench connecting block is arranged between the nut limiting seat and the ratchet wrench. The connecting block of the ratchet wrench aims at increasing the distance between the ratchet wrench and the clamp body, and is matched with the Z-shaped inward bending structure of the swing arm to leave enough space for wrench movement; and secondly, the convenience of connection between the ratchet wrench and the nut limiting seat is improved, and enough space is reserved for the inner hexagon of the nut limiting seat to be used for sleeving the outer hexagon of the foot nail nut.
The corners of the clamp main body are in arc transition. The purpose of adopting circular arc transition is in order to reduce the roughness of corner, prevents to grind or cut the hand of fortune dimension personnel.
The adjusting nut is a plum nut. The plum nut is adopted, so that the plum nut can be directly unscrewed or screwed by means of the hand strength of an operation and maintenance worker.
The method of use of this embodiment is the same as that of the embodiment.
It is clear to those skilled in the art that, for convenience and brevity of description, the specific working processes of the above-described systems, apparatuses and units may refer to the corresponding processes in the foregoing method embodiments, and are not described herein again.
