Detailed description of the invention

The present invention is a kind of general utility tool dismantling multiple component of machine, directly can dismantle the multiple parts such as working roller of straightening machine jaw, motor catcher, axle journal gear.

The present invention is made up of travelling car 1, fluid pressure drive device, provision for disengagement three part.

Fluid pressure drive device is fixed on travelling car 1, provision for disengagement is connected with fluid pressure drive device, fluid pressure drive device drives provision for disengagement working roll jaw 9, motor catcher 15, the multiple parts such as axle journal gear to be pulled down, travelling car 1 can movable hydraulic drive unit and provision for disengagement and multiple diverse location to be disassembled parts corresponding.

Show in figure, fluid pressure drive device comprises hydraulic power unit 2, hydraulic cylinder height adjustment bracket 3, hydraulic cylinder 4.Hydraulic power unit 2 and hydraulic cylinder height adjustment bracket 3 are fixed on travelling car 1, the cylinder body of hydraulic cylinder 4 is arranged on hydraulic cylinder height adjustment bracket 3, hydraulic cylinder 4 can be moved up and down at hydraulic cylinder height adjustment bracket 3 by adjusting nut 13, hydraulic cylinder height adjustment bracket 3 can the height of regulator solution cylinder pressure 4 with to be disassembled the height of parts suitable.The fluid pressure line of hydraulic power unit 2 is connected with hydraulic cylinder 4, and hydraulic cylinder 4 has oil-in 11, oil return opening 12, and the push rod of hydraulic cylinder 4 promotes provision for disengagement and carries out field-strip.

Provision for disengagement of the present invention can be divided into two classes according to being disassembled parts, and a class is working roller of straightening machine jaw, and another kind of is motor catcher and gear, belt pulley etc.

Working roller of straightening machine jaw 9 is arranged on working roll 10 axle head, adopts slide block type to connect with universal-joint spindle.Working roll axle journal and jaw are interference fit, its maximum magnitude of interference δ max=0.028mm, length of fit is 240mm, pressing-in force F is very large, be 138.2T as calculated, cannot remove by jack stand dismounting method and artificial gas cutting heating dismounting method, originally each replacing working roller of straightening machine is all cut off jaw by air gun, both waste of manpower, strengthens cost and easily damages the working roll diameter of axle again.

Motor catcher 15 is arranged on motor shaft 16, interference fit, pressing-in force is 62.3T as calculated, very difficult by jack stand dismounting method, efficiency is extremely low, and removing a motor catcher after carrying out support at least needs about 2 hours, and 15 catchers of generally having an appointment during the assembling of printed line on site spare need to remove, total dismounting time is oversize, affects other job placements.Other gear is taken over identical with the situation of belt pulley with motor.

Show in figure, the device of dismounting working roller of straightening machine jaw class of the present invention comprises connecting ring 5, connecting rod 6, push rod 8 and jig.The inner hole wall of connecting ring 5 has screw thread, the outer wall of hydraulic cylinder 4 front end there is screw thread, the endoporus of connecting ring 5 is spun on the outer wall of hydraulic cylinder 4 front end, the anchor ring of the both sides of connecting ring 5 there is connecting hole, one end of two connecting rods 6 is each passed through the connecting hole of connecting ring 5 both sides by fastening nuts, the other end of two connecting rods 6 is connected with jig, and one end of push rod 8 is connected with fluid pressure drive device, and the other end of push rod 8 is with to be disassembled parts relative.

Jig is mandrel 7, and the effect of mandrel 7 is location jaws 9, not sideslip in loading process.The middle part of mandrel 7 is cylinder, and cylinder matches with the entry of jaw 9 one end be disassembled, and is designed with circular positioning table, for the location of mandrel 7 at the vertical direction of jaw above cylinder.The cylindrical two ends of mandrel 7 are welded with baffle plate respectively, and baffle plate has connecting hole, and the other end of connecting rod 6 passes connecting hole by fastening nuts.Push rod 8 is cylinder axis, by the through hole at mandrel 7 center, be arranged on the center of whole provision for disengagement, be mainly used in the driving force of transmission fluid cylinder pressure 4, the push rod of one end connecting fluid cylinder pressure 4 of push rod 8, the other end is relative with the working roll 10 installing jaw 9, drives push rod 8, can realize the quick-detachment of jaw 9 by hydraulic cylinder 4.

Show in figure, the device of dismounting motor catcher 15 of the present invention, gear, belt pulley class comprises connecting ring 5, connecting rod 6, push rod 8 and jig equally.The connecting ring 5 of the structure of connecting ring 5, connecting rod 6, push rod 8 and mounting means and the device of dismounting working roller of straightening machine jaw, connecting rod 6, push rod 8 are identical, and jig is then different according to the structure being disassembled parts.

Jig is baffle plate 14, and baffle plate 14 is rectangular slab, and there is U-shaped opening the side, middle part of baffle plate 14, and there is equidistant connecting hole in the plate face of U-shaped opening both sides, and two connecting rods 6 are each passed through connecting hole by fastening nuts.Push rod 8 is through the U-shaped opening of baffle plate 14, and one end of push rod 8 is connected with the push rod front end of hydraulic cylinder 4, the other end of push rod 8 and installation be disassembled motor take over 15 motor shaft 16 relative.Connecting rod 6 and baffle plate 14 with the use of, the U-shaped open card of baffle plate 14 is at the boss position of motor catcher 15, and for extracting gear, motor catcher 15 or belt pulley etc., connecting rod 6 realizes the adjustment of length by the nut of adjustment end.

Using method of the present invention is as follows:

The using method of dismounting working roller of straightening machine prong device:

With overhead traveling crane, smoothing roll (containing jaw) is hung correct position, clear within requirement jaw direction 2m, shift hydraulic trolley 1 onto jaw front, regulated the adjusting nut 13 on height bracket 3 by hydraulic cylinder, fast by the plunger central lift of hydraulic cylinder 4 to jaw 9 center on same level line.The mode that connecting ring 5 is threaded connection is assembled on the cylinder body of hydraulic cylinder 4, mandrel 7 is inserted into jaw 9 inner, utilize connecting rod 6 that connecting ring 5 and mandrel 7 are linked to be a stressed entirety, by the center of push rod 8 through mandrel 7, be placed in the middle of hydraulic cylinder 4 and working roll 10, electric button in operation hydraulic trolley 1, makes hydraulic cylinder 4 push rod forward motion, drives push rod 8 to be extracted from working roll 10 by jaw 9.

The using method of the devices such as dismounting motor catcher, gear, belt pulley:

With overhead traveling crane, motor (containing motor catcher 15) is hung correct position, clear within requirement motor catcher direction 2m, shift hydraulic trolley 1 onto motor and take over 15 fronts, by the adjusting nut 13 on regulator solution cylinder pressure height adjustment bracket 3, fast by the push rod central lift of hydraulic cylinder 4 to motor shaft 16 center on same level line.The mode that connecting ring 5 is threaded connection is assembled on the cylinder body of hydraulic cylinder 4, by the boss position of the U-shaped open card of baffle plate 14 at motor catcher 15, utilize connecting rod 6 that connecting ring 5 and baffle plate 14 are linked to be a stressed entirety, push rod 8 is placed in the centre of hydraulic cylinder 4 and motor shaft 16, electric button in operation hydraulic trolley 1, make the push rod forward motion of hydraulic cylinder 4, drive push rod 8 to be extracted from motor shaft 16 by motor catcher 15.
