Abstract
The invention relates to a screw extractor, in particular to a high frequency induction heating screw extractor. The invention solves the problem that the existing screw extractor is hard to disassemble some shaft fastening pieces with tight fit. The high frequency induction heating screw extractor comprises a mandrel and a falcula connected with the mandrel and also comprises a group of high frequency induction heaters, wherein a magnet is arranged on one end of each high frequency induction heater. Compared with the traditional screw extractor, the heating device is added on the high frequency induction heating screw extractor of the invention; and the gaps between the parts to be disassembled can be increased by heating so as to greatly reduce the friction force between the parts to be disassembled, largely increase the drawing ability of the screw extractor and protect the parts to be disassembled and the personal safety of the site operation personnel.
Description
Technical field
The present invention relates to draw horse, be specially high frequency induction heating screw extractor.
Background technology
Draw horse to be also referred to as thruster, be widely used in dismantling axles such as various shaft couplings, gear, bearing, belt pulley and tighten part, it is made of with the hook two parts that are connected (or hinged) with push rod push rod, push rod is divided into screw rod and two kinds of forms of jack, and hook is divided into two kinds of two pawl formulas and three-pawl types, catches the object that draws with hook during use, rotary screw formula push rod or eject the jack type push rod, push rod is steadily advanced forward, and claw hook is corresponding to be retreated, being drawn object to pull out.
Existing draw horse in dismounting some cooperate when the axle of pine tightens part very convenient effectively, but some cooperate tighter axle to tighten especially unusual difficulty sometimes during larger-size part of part in dismounting, reason is owing to the excessive frictional force that causes of the assembling magnitude of interference between the demolition part is very big, the pulling capacity of drawing horse to produce is not enough to overcome this frictional force, so demolition part can not be pulled out.Because resistance is crossed ambassador's hook and can not will be drawn object normally to pull out, can not normally eject owing to push rod simultaneously, make La Manei accumulate a large amount of mechanical energy, may cause accident, serious threat site operation personnel's safety and the safety that is disassembled equipment such as being drawn object fracture or hook unhook.
Summary of the invention
The present invention draws horse to be difficult to dismantle the problem that the tighter axle of some cooperations tightens part in order to solve to have now, and a kind of high frequency induction heating screw extractor is provided.
The present invention adopts following technical scheme to realize: high frequency induction heating screw extractor, comprise push rod and the hook that is connected with push rod, and also comprise one group of high frequency induction heater, an end of each high frequency induction heater is equipped with magnet.During use, earlier high frequency induction heater is adsorbed on the surface of demolition part, according to the size on the surface of demolition part or the requirement of programming rate, the high frequency induction heater of absorption respective numbers, to draw horse to be installed on the demolition part and suitable pre-applied force then, connect high frequency induction current then, the outer surface of demolition part is heated rapidly, keep temperature-resistant and the axle that is disassembled is basic, under the effect of expanding with heat and contract with cold, demolition part expands and axle does not expand, and the degree of interference fit between the demolition part is descended, thereby significantly reduce the frictional force between the demolition part, demolition part is drawing under the effect of horse pre-applied force loosening when the fit clearance between the demolition part increases to certain value, begin to separate, at this moment continue to eject the push rod that draws horse, demolition part will easily be separated.
High frequency induction heating screw extractor of the present invention draws horse to compare with tradition and has set up heater; can increase the gap between the demolition part and significantly reduce frictional force between the demolition part by heating; thereby significantly improve the drawing ability of drawing horse; can protect the safety of demolition part and site operation personnel's personal safety; simultaneously because the significantly raising of high frequency induction heating screw extractor ability to work; the drawing ability specification of drawing horse to compare high frequency induction heating screw extractor with tradition in the middle of same field-strip descends; thereby make the corresponding minimizing of the volume and weight that draws horse; significantly reduce the cost of equipment that draws horse, alleviate the labour intensity of drawing operation.Heater is made as independently blockage (being that heater is one group of high frequency induction heater) of heating system, one end setting-in magnet, can the respective numbers heater be installed according to the different appearance and sizes of heating object during use, to guarantee to add heat, programming rate, this structural design novelty, uniqueness, easy to use.
Description of drawings
Fig. 1 is the structural representation of high frequency induction heating screw extractor of the present invention;
Among the figure: 1-jack, 2-push rod, 3-high frequency induction heater, 4-hook, 5-demolition part, the axle of 6-demolition part.
The specific embodiment
High frequency induction heating screw extractor comprises push rod 2 and the hook 4 that is connected with push rod 2, also comprises one group of high frequency induction heater 3, and an end of each high frequency induction heater is equipped with magnet.Push rod 2 is the form of jack 1 in this specific embodiment.Described high frequency induction heater 3 adopts existing product.
During use, earlier high frequency induction heater 3 is adsorbed on the surface of demolition part 5, according to the size on the surface of demolition part or the requirement of programming rate, the high frequency induction heater of absorption respective numbers, to draw horse to be installed on the demolition part 5 then, suitably eject jack type push rod 2 with suitable pre-applied force, connect high frequency induction current then, the outer surface of demolition part is heated rapidly, and the axle 6 basic maintenances of demolition part are temperature-resistant, under the effect of expanding with heat and contract with cold, demolition part expands and axle does not expand, degree of interference fit between the demolition part is descended, thereby significantly reduce the frictional force between the demolition part, demolition part is drawing under the effect of horse pre-applied force looseningly when the fit clearance between the demolition part increases to certain value, begins to separate, at this moment continuing to eject the push rod that draws horse, demolition part will easily be separated.
