Abstract

The internal electric cable capstan consists of an electric motor, a speed reducer, a terminal box, a wire winding drum and a fixed inner barrel. The electric motor is fixed inside of the fixed inner barrel. The fixed inner barrel is kept to be steady inside of the wire winding drum through a fixed support shaft and a fixed base. The connecting cables of the electric motor are connected with the terminal box through a hollow hole in the fixed support shaft. The speed reducer adopts a cycloid cam structure. The shell of the speed reducer is fixed to the right end face of the inner barrel. The motor shaft is inserted into the eccentric shaft sleeve of the speed reducer to drive the speed reducer. The output mechanism drives the wire-winding drum to rotate and achieves the take-up and payoff of the electric cables through a power shaft. The utility model installs the electric motor and the speed reducer into the fixed inner barrel of the drum and the drum utilizes the cooling fan of the electric motor to realize natural ventilation, which therefore prevents the electric cable rubber sleeve from being polluted by the oil leakage. The utility model is designed with a simple and compact structure, which facilitates the arrangement of a plurality of electric cable capstans working in parallel with each.

Description

A kind of new-style internal cable capstan

Technical field

The utility model relates to a kind of electronic cable reel installation, especially actuating device and speed reduction gearing is contained in the electronic cable hoist of cable hoist cylinder the inside.

Background technology

At present cable hoist have manually, hydraulic-driven and several patterns of power drive.

For external diameter at the cable of Φ more than 35, the manual corresponding difficulty of folding and unfolding, and the hydraulic-driven cost is very high, and have the danger of oil leaking pollution cable rubber cover.

Traditional electronic cable hoist drives cable hoist by chain with electrical motor and carries out work after speed reduction gearing slows down, transmission device is complicated and take bigger operational space, and for several cable hoists situation arranged side by side, transmission device is difficult to arrange.

The utility model content

In order to overcome the deficiency of above three kinds of cable hoists, the utility model provides a kind of new-style internal cable capstan, and is easy and simple to handle, and integral structure is simple, compact, make several cable hoists easy arrangement that becomes of working arranged side by side simultaneously, and avoided the danger of oil leaking pollution cable rubber cover.

A kind of new-style internal cable capstan provided by the utility model, comprise electrical motor, retarder, connection box and winding drum, it is characterized in that: it comprises that also one is contained in the fixedly inner core in the winding drum, wherein: described electrical motor is contained in this fixedly in the inner core, fixedly inner core passes through fixed-bearing axis, fixed bearing makes it keep quiescence in the winding drum the inside, the connecting cable of electrical motor is to receive connection box by the hole of fixed-bearing axis hollow, again: described retarder adopts the cycloidal-pin wheel structure, the shell of retarder is fixed on fixedly inner core right side, the excentric sleeve that motor shaft inserts retarder drives the retarder running, drives the winding drum rotation by output mechanism by power take-off shaft and realizes the folding and unfolding cable.

Above-mentioned new-style internal cable capstan clamps a shim rubbery loop respectively on cable two end plates.

Above-mentioned new-style internal cable capstan, wherein: the winding drum two end cap and fixedly the two end cap of inner core all have ventipane.

Adopted above-mentioned technical solution, that is: in the fixedly inner core in electrical motor and the retarder threading cylinder, cylinder utilizes the cooling fan natural ventilation cooling of electrical motor, has avoided the situation of oil leaking pollution cable rubber cover to take place.As long as energized just can make cylinder rotate, finish the folding and unfolding operation of cable.In addition, retarder adopts the cycloidal-pin wheel structure, has simple in structurely, and reduction ratio is big, the advantage that load-carrying capacity is big.It is simple, compact to the utlity model has integral structure easy and simple to handle, makes several cable hoists easy arrangement that becomes of working arranged side by side simultaneously.

The specific embodiment

Shown in Fig. 1～2, a kind of new-style internal cable capstan of the utility model, electrical motor 8 is contained in fixedly inner core 9 the insides, retarder 10 adopts the cycloidal-pin wheel structure, the shell of retarder 10 is fixed on fixedly inner core right side, drive the retarder running in the excentric sleeve of motor shaft insertion retarder, finish the work of retractable cable by 7 rotations of power take-off shaft 11 drive winding drums by the output mechanism of retarder.Shim rubbery loop 6 is clamped on the cable end plate 5, and manual jiggering is become smoothly.

Cable end plate 5 bolt ups are on winding drum 7.Fixed-bearing axis 3 is a hollow structure, and the connecting cable of electrical motor connects connection box 1 by this hole.Connection box 1, fixed bearing 2, fixed-bearing axis 3, fixedly inner core 9, electrical motor 8 and retarder 10 shells are the fixed part of the electronic cable hoist of the utility model, the output mechanism of retarder and power take-off shaft 11 are rigidly connected, and drive winding drum and rotate in the supporting device of bearing 12 and antifriction-bearing box 4 compositions.Retarder 10 is used grease lubrication, winding drum 7 two end cap 5 and fixedly the two end cap of inner core 9 all have ventipane 13,14, the cooling fan of electrical motor 8 carries out natural ventilation cooling, the oil contamination phenomenon of having avoided electrical motor 8 and retarder 10 outer transmissions to cause to electrical motor 8 and retarder 10.

Cable hoist is operated very easy by change-over swith control motor forward and backward.
