Abstract
The utility model provides a lifting hook for a steel pipe. The lifting hook comprises a hook body, wherein a hook head for hooking the end part of the steel pipe and a lifting arm matched with the wall of the steel pipe are arranged on the hook body, a lifting ring is arranged at the top end of the lifting arm, magnetic attachment devices are arranged on the two sides of the lifting arm, the magnetic attachment devices comprise supports fixed on the lifting arm, copper sleeves are arranged on the supports, and attachment magnets are loaded inside the copper sleeves. According to the lifting hook provided by the utility model, as the magnetic attachment devices are mounted on the hook body, the hook body can be stably fixed on the wall of the steel pipe, not only is the hooking frequency by a worker reduced to facilitate the operation by the worker, reduce labor intensity and improve working efficiency, but also the times for the worker to climb a good stock up and down can be reduced to ensure the operation safety of the worker.
Description
Technical field
The utility model relates to a kind of suspension hook, particularly a kind of steel pipe lifting hook.
Background technology
The loading and unloading of loose Zhi Gangguan, mainly adopt special gib head, hooks the tube wall at steel pipe two ends, realizes the lifting of steel pipe.In order to improve handling efficiency, the steel pipe of some diameters below 800mm, adopt suspender in groups, and each rising is hung in more than three, and there are three above gib heads in suspender both sides branch.In operation process, stood on steel pipe by two workmans, respectively suspender two group of branches are drawn to the two ends of steel pipe, gib head is hooked on tube wall.Because steel pipe is round, after workman's hook, glide or break away from tube wall along tube wall in order to prevent gib head, must hold backward steel rope, allow the tight hook tube wall of gib head on tube wall, slide or to come off to prevent gib head, then could command the machinery lifting.While especially lifting by crane the branched steel pipe of minor diameter, because the pile spacing is larger, several hoisting wireropes of steel pipe one end are deposited fan-shaped distribution, it is large that outermost end steel rope angle becomes, and causes the lateral force of gib head just greatly, and numerous time of coming off from tube wall of gib head is higher, sometimes one group of steel pipe of machinery lifting will repeatedly hook up just and can complete loading and unloading, increasing labor strength, affecting handling efficiency simultaneously, the workman also wants constantly upper and lower goods buttress, has certain potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, provides a kind of reasonable in design, can hold gib head and from tube wall, not come off, and lifting does not need the workman to hold the steel pipe lifting hook of steel rope during steel pipe.
Technical problem to be solved in the utility model is to realize by following technical scheme, the utility model is a kind of steel pipe lifting hook, be characterized in: comprise coupler body, coupler body is provided with the gib head that hooks steel tube end part and the arm coordinated with the steel pipe tube wall, the top of arm is provided with suspension ring, and the both sides of arm are provided with the magnetic absorption device, and described magnetic absorption device comprises the support be fixed on arm, support is provided with copper sheathing, and absorption magnet is housed in copper sheathing.
Technical problem to be solved in the utility model can also further realize by following technical scheme, is provided with pourable resin chock on the adsorption plane of absorption magnet.
Technical problem to be solved in the utility model can also further realize by following technical scheme, and described copper sheathing is provided with two, is symmetricly set on the arm both sides.
The utility model is by being equipped with the magnetic absorption device on coupler body, can make very firm being fixed on the steel pipe tube wall of coupler body, compared with prior art, it has not only reduced the workman and has linked up with the frequency, facilitate the workman to operate, reduce labour intensity, improved work efficiency, and reduced the workman and climbed up and down the number of times that goods is piled up neatly, for workman's operation has brought safety.
The accompanying drawing explanation
Fig. 1 is that the utility model is used the status architecture schematic diagram.
Fig. 2 is the structural representation of magnetic absorption device.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the utility model further, and do not form the restriction to its right.
With reference to accompanying drawing 1 and Fig. 2, a kind of steel pipe lifting hook, comprise coupler body, coupler body is provided with the gib head 3 that hooks steel tube end part and the arm 2 coordinated with the steel pipe tube wall, the top of arm 2 is provided with suspension ring 1, and the both sides of arm 2 are provided with the magnetic absorption device, and described magnetic absorption device comprises the support 5 be fixed on arm 2, support 5 is provided with copper sheathing 4, and absorption magnet 6 is housed in copper sheathing 4.
Owing in operation, overpaying suspender, use in groups, suspender both sides branch coupler body than multipacting together, if the magnetic of magnetic absorption device is too strong, between coupler body, will attract each other, or peripheral object is produced to unnecessary absorption, but will adsorb magnet 6, just be contained in copper sheathing 4 and do not there will be this phenomenon, facilitated the workman to divide the hook operation.
During use, the gib head of each coupler body 3 is hooked to steel tube end part, the absorption magnet 6 on coupler body arm 2 is adsorbed on the steel pipe tube wall, and while carrying out so next coupler body operation, this coupler body just can be unmovable, can lift by crane after all suspension hooks fix.
On the adsorption plane of absorption magnet 6, be provided with pourable resin chock 7, allow magnet directly not contact with the steel pipe tube wall, adjust the suction of magnet to tube wall by the thickness of adjustment pourable resin chock 7, prevent that suction is too large, use like this and easily take off afterwards, facilitate the workman to operate.
Described copper sheathing 4 is provided with two, is symmetricly set on arm 2 both sides, and coupler body and steel pipe absorption are more firm like this, and coupler body is more difficult to come off.
