Abstract

The utility model discloses a double-chamber wiring lifting electromagnet. A wiring chamber of the double-chamber wiring lifting electromagnet is divided into an inner chamber and an outer chamber which are separated through a partition board. A wiring column in the wiring chamber penetrates through the partition board through an insulation sleeve and is fixed on an inner chamber wall and an outer chamber wall through the partition board, two ends of the wiring column are respectively arranged in the inner chamber and the outer chamber, an inner chamber end of the wiring column is connected with an excitation wire, and an outer chamber end of the wiring column is connected with a cable. The double-chamber wiring lifting electromagnet is reasonable in design, due to the fact that the external cable of the lifting electromagnet is pressed by a wire pressing base, the external cable is connected with an inner excitation coil through a double-chamber wiring structure, when strong tension is exerted on the cable, the pulled breaking point of the cable is usually on the portion of the wire pressing base and a wiring portion of the outer chamber, the inner chamber structure cannot be damaged, the part of the excitation coil of the lifting electromagnet cannot be damaged, and accordingly amount of maintenance work of the lifting electromagnet is greatly reduced. The probability that the inner excitation coil is damaged and has to be rejected caused by breaking of the cable is reduced, and practical applicability of the lifting electromagnet is improved.

Description

Two-chamber wiring lifting electromagnet

One, technical field

The utility model relates to the mode of connection of the excitation coil and the cable of a kind of lifting electromagnet, particularly electromagnet.

Two, background technology

Lifting electromagnet has been widely used in steel transport operation places such as iron and steel enterprise, harbour, and field of application progressively enlarges.Its flexible operation, advantage easy to use make steel carrying link have higher efficient and safer production tooling.Yet electromagnet when the handling steel because field condition is comparatively complicated; Therefore the mode of connection of electromagnet is required also comparatively harsh, if the cable of electromagnet draw when longer, the rising of steel, let slip and very easily be pressed onto cable in the journey; Cause the cable damage, for safety is brought hidden danger; If cable more in short-term, overhead traveling crane is very easily broken cable even excitation wire in operational process.And excitation wire is to draw on the excitation coil after being filled by potting compounds such as epoxy resin, in case broken, just is difficult to draw intact the end of a thread once more and is connected with cable.Thisly break the trouble that excitation wire causes and bring very big puzzlement for the use of lifting electromagnet, therefore be badly in need of at present a kind ofly can solving above-mentioned cable by the mode of connection of being convenient to keep in repair after breaking.

Three, summary of the invention

The purpose of the utility model provides a kind of two-chamber wiring lifting electromagnet, can overcome the prior art lifting electromagnet and be prone to wiring hidden danger, the inconvenient problem of on site maintenance, has improved the convenience of electromagnet maintenance greatly.

The technical scheme that the utility model adopts is: two-chamber wiring lifting electromagnet has wire connection cavity; Pass through the wire connection cavity connection cable from the excitation wire that excitation coil is drawn; The wire connection cavity of the utility model is divided into inner chamber and exocoel, has dividing plate to separate between the inside and outside chamber, and the binding post in the wire connection cavity covered dividing plate through insulation; And in being fixed on through dividing plate on the outer chamber wall; Binding post two ends branch is in inner chamber and the exocoel, and the inner chamber end of binding post is connected with the excitation wire of drawing from the lifting electromagnet excitation coil, and the exocoel end of binding post is connected with cable.

The excitation wire of the utility model links to each other with the inner chamber end of binding post through the copper-aluminium transition nose; The exocoel end of binding post is connected with cable through the termination of colding pressing.

Outside wire connection cavity, in the cable threading, compress by the line ball seat again, with two wire type hoops cable and sleeve pipe are connected as one.

The utility model is reasonable in design; Because the lifting electromagnet External cable is compressed by the line ball seat; External cable is connected by the two-chamber wiring construction with inner excitation coil, and the breakpoint that cable is broken when cable receives stronger pulling force generally in line ball seat place and exocoel wiring place, can not damage inner-cavity structure; More can not damage the excitation coil part of lifting electromagnet, thereby alleviate the maintenance load of lifting electromagnet greatly.Greatly reduce because of cable and break the probability that causes inner excitation coil damage to have to scrap, strengthened the practicality of lifting electromagnet.

Five, the specific embodiment

The chamber that connects of the utility model is divided into inner chamber 5 and exocoel 8; The excitation wire 12 of drawing from excitation coil 13 links to each other with the excessive nose 11 of copper aluminium; The excessive nose 11 of copper aluminium links to each other with the binding post that is connected inside and outside two-chamber 6 more then; Binding post 6 is fixed with interior outer chamber wall through insulation sleeve 10, dividing plate 7, and the exocoel end of last binding post 6 links to each other with the termination 9 of colding pressing again, and then joins with External cable 1.Outside wire connection cavity, be fixed cable 1 through line ball seat 3, in order to protect cable 1, cover one deck sleeve pipe 4 in cable 1 outside is fixing with two to three pairs wire type hoop 2 again.

The utility model is fixing mainly at Liang Chu to cable 1, and the one, 3 pairs of cables 1 of line ball seat fixing, the 2nd, outer cavity segment is fixed cable 1.And because the inner chamber part is an one with lifting electromagnet inside; All being similar to the perfusion of epoxy resin lacquer solidifies; Intensity is very high generally to be not easy damage from the pullling of External cable, and therefore breakpoint generally just is concentrated in this two place when cable 1 receives strong pulling force.During fracture, when maintenance, only need at first pull down line ball seat 3 when cable 1 so long as in the outside of cavity, open outer cavity segment then, pull down the termination 9 of colding pressing, change a cable again and be connected on the binding post 6 and get final product.The utility model is widened the Applicable scope of lifting electromagnet greatly, and various complicated harsh work condition environments can be used by safe ready.
