Abstract
The invention discloses a magnetic fixing device, comprising a permanent magnet, a magnet fixing block and at least one jack bolt with a handle; the magnetic fixing block wraps the permanent magnet or is wrapped by the permanent magnet, the magnet fixing block is used for fixing the permanent magnet and can also play the role of protecting the permanent magnet, the jack bolt with the handle is screwed in through a screw hole and can penetrate the magnet fixing block, when in such action, the permanent magnet and the magnet fixing block can be absorbed on the surface of an absorbed object, then, the fixation operation can be carried out by tying a rope on the magnet fixing block or the handle, when in need of releasing the fixation, the rope is released, the handle is gripped to screw the bolt, and then the bolt goes forward to the surface of the absorbed object to jack the surface of the absorbed object, thereby lifting the permanent magnet and the magnet fixing block to leave the contact surface. The magnetic fixing device has simple and reliable overall structure, strong stability, easy assembly and disassembly with less labour and convenient operation, so that the magnetic fixing device can be widely applied in operations in spherical tanks of petroleum, chemical and other industries and can also be used in other occasions with the need of temporary fixation.
Description
Technical field
The present invention relates to the engineering equipment of operation in a kind of spherical tank, relate in particular to the fixture of job platform in a kind of spherical tank.
Background technology
Spherical tank is the especially a kind of production equipments that all will use of oil play of many enterprises, in order to guarantee production safety, must regularly detect, maintenance, method near detection faces has at present: 1, set up scaffold---traditional means near the scope of operation, though can guarantee to be close to any detection faces well, but assembly and disassembly inconvenience, manpower and materials require high, economic pressures are big, coefficient of safety is lower, time spent is very long, owing to can't putting into production, spherical tank bring part producing to stop operation, problem that the labour is idle or the like can cause enormous economic loss to enterprise; 2; with the highwire is protection; come to locate by bamboo pole or other stock or simple and easy scaffold to the operator; to reach the change direction; purpose near detection faces; utilize this method can carry out operation at any time; the manpower and materials of employing are less relatively; economic pressures are relatively low; but coefficient of safety is not high yet; operating personnel's work is very arduous; and take place to rock strongly; the risk of injury to personnel is bigger; therefore the applicant has invented with unsteady job platform and has flown on the liquid level; constantly regulate the job position face by the adjusting liquid level and progressively finish detection; the method of maintenance; but a problem that is faced in operation process is to need both can easily temporary fixedly live to float job platform and can remove fixing when shifting one's position flexibly when a position operation; adsorbing by permanent magnet fixedly is a kind of more convenient simple and direct mode, is difficult to draw back but want to draw back after permanent magnet is attached on the spherical tank just to require great effort very much again.
Summary of the invention
Problem to be solved of the present invention provides a kind of simple in structure, easy accessibility, safe and reliable, fixing and remove fixing all very convenient labour-saving magnetic force fixed device.
The technical solution adopted in the present invention is: magnetic force fixed device comprises permanent magnet and magnet fixed block; the jack bolt that at least one is with handles; described magnet fixed block encases permanent magnet or is encased by permanent magnet; the magnet fixed block preferably adopts the magnetic metal material; described magnet fixed block is in order to fixing permanent magnet; can also play the effect of protection permanent magnet; described jack bolt with handles is screwed into by screw and can passes the magnet fixed block; after doing on the surface that the time spent can be adsorbed on permanent magnet and magnet fixed block absorbate like this; fasten on magnet fixed block or handle with rope and can carry out fixing operation; when needs are removed fixedly; unclamp rope; hold handle then and turn bolt; bolt is advanced towards the absorbate surface; withstand the absorbate surface like this, permanent magnet and magnet fixed block are lifted leave contact surface.
For make turn smoothly more convenient; described jack bolt up knob with handles middle part is provided with the strip hole in order to pass staff four fingers; this hole also can be in order to fasten rope simultaneously; certainly; also can establish the lanyard ring in addition, described lanyard hole be arranged on the magnet protection piece or on the handle of jack bolt in order to fasten rope.
In order to make magnetic force fixed device and absorbate applying adsorbed close Li Genggao, be the plane of matching with the absorbate phase-contact surface on described magnet fixed block and/or the permanent magnet with the absorbate phase surface, phase-contact surface is the identical sphere of radius when contacting promptly as with concave spherical surface, and phase-contact surface can be the plane when adsorbing mutually with very big sphere of spherical radius or plane.
Also be provided with fastener between described permanent magnet and the magnet fixed block so that fixing more reliable between permanent magnet and the magnet fixed block, fastener preferably includes and is arranged at screw and the trip bolt that leads to permanent magnet on the magnet fixed block, and described trip bolt is screwed into screw and holds out against permanent magnet and reach fastening purpose.
Jack bolt can not unclamped by mistake when the stationary rope in order to make, also be provided with stopping device on the described jack bolt with handles, preferred stopping device comprises packing ring and screw, the external diameter of packing ring is greater than the jack bolt diameter, the screw that screw is screwed into jack bolt afterbody center is fixed on the jack bolt with packing ring together, on the described magnet fixed block fixedly the screw afterbody of jack bolt be provided be not less than the packing ring diameter counterbore in order to hold packing ring, like this turn bolt when falling back on packing ring and contacting with the counterbore face bolt can not withdraw from again.
More laborsaving in order not injure the absorbate surface when the jack-up and to make jack-up, preferred described jack bolt afterbody is smooth cambered surface or sphere.
The invention has the beneficial effects as follows: after the present invention is fixed together permanent magnet and magnet fixed block fixedly the time, be placed on the absorbate surface, can be under magneticaction device be fixed on the absorbate surface, fixing rope again gets final product, when needs are shifted one's position, the jack bolt that turns on it can make whole fixture and absorbate be separated, then take off just be easy to laborsaving, overall structure is simple and reliable, stability is strong, easy disassembling is laborsaving, easy to operate, can be widely used in oil, operation in the spherical tank of industries such as chemical industry also can be used for the temporary fixed occasion of other needs.
