Abstract

The invention belongs to construction piling machinery and discloses an electromagnetic pile hammer which structurally comprises a bidirectional armored screw tube type electromagnet with a guide magnetic pole. An armature serves as a pile hammer, an upper fixed iron core and a lower fixed iron core are stop-iron-free iron cores with guide magnetic poles, an upper exciting coil and a lower exciting coil are arranged between the outer side of each fixed iron core and the inner side of a shell, an intermediate magnetic pole is arranged in the middle of the inner side of the shell, the upper end of the armature is provided with a concave hole, and an energy storage spring is mounted in the concave hole. When the electromagnetic pile hammer is in operation, the upper and lower exciting coils are electrified in turns, the armature (pile hammer) moves up and down to hammer a pile cap to strike a pile into earth. The electromagnetic pile hammer is simple in structure, free of pollution, lightweight and low in cost.

Description

The electromagnetism pile monkey

Technical field: electromagnetism pile monkey of the present invention belongs to piling machinery for building.

The shortcomings such as background technology: now widely used pile monkey has diesel hammer, hydraulic hammer, electrically operated hammer, and they have respectively contaminated environment, and structure and hydraulic system are complicated, and be fragile.

Summary of the invention: the present invention is a kind of electromagnetism pile monkey, its basic structure be one have the guiding magnetic pole two-way armoring solenoid electromagnet, electromagnet up and down fixed core is without buting iron, the guiding pole core is arranged, consequent pole is arranged between fixed core up and down, and respectively there is one group of magnetizing coil in the fixed core outside up and down, and armature is cylindricality, top is fluted, energy-stored spring is arranged in the groove, and there is tup the lower end, upper fixed core top and have lower fixed core bottom that approach switch respectively is housed.

The present invention replaces diesel hammer, hydraulic pressure hammer, electrically operated hammer, electromagnet rank to be pile monkey, its simple in structure, low cost of manufacture by the bidirectional electromagnet that the guiding magnetic pole is arranged.

Description of drawings: Fig. 1 is a kind of electromagnetism pile monkey structural representation of the present invention.1 armature among the figure-pile monkey; 2 tups; Fixed core on 3; 4 times fixed cores; 5 consequent poles; 6 shells; Magnetizing coil on 7; 8 times magnetizing coils; 9 energy-stored springs; 10 rubber cushions; 11 cover plates; Approach switch on 12; 13 times approach switchs; 14 junction boxes; 15 safety cards.

The specific embodiment: accompanying drawing 1 is depicted as a kind of electromagnetism pile monkey structural representation, 1 armature among the figure-pile monkey, during the initial loading attitude under place's what in the fixed core 4 guiding magnetic poles, when starting working, upper magnetizing coil 7 energisings, armature moves upward, compressed energy-storage spring 9, when armature upper end and upper fixed core 3 bottoms near the time, upper approach switch 12 actions, make magnetizing coil 7 outages, connect simultaneously lower magnetizing coil 8, armature produces magnetic force at lower magnetizing coil, the potential energy that the armature ascending motion obtains, move downward under the kinetic energy acting in conjunction that stores during spring-compressed, the armature lower end squeezes in the soil stake by tup 2 hammering pile covers, meanwhile bottom approach switch 13 actions, make lower magnetizing coil outage, magnetizing coil in the connection makes and so forth electromagnet armature drive tup and moves up and down.

Claims

1. one kind is the electromagnetism pile monkey of main body by the two-way armoring solenoid electromagnet that the guiding magnetic pole is arranged; By armature, the up and down fixed core of guiding magnetic pole is arranged, consequent pole, the up and down compositions such as two groups of magnetizing coils, shell, energy-stored spring, approach switch without buting iron; Be characterised in that basic structure be one have the guiding magnetic pole two-way armoring solenoid electromagnet, fixed core is without buting iron up and down the guiding pole core.
