Description
Technical field
The utility model relates to a kind of electric block, specifically relates to a kind of lifting limited device of electric block.
Background technology
The Motor Driven Elevating Calabash inhibiting device of present use relies on the rope winding jib that cylinder is installed to control, rope winding jib and steel rope must run according to the track on cylinder, in the working environment that some is different, and add the inadvertent of operation driver and commanding, occur that askew the skewing of steel rope hangs phenomenon unavoidably, be therefore easy to damage rope winding jib; Make upper and lower spacing ineffective, occur that steel rope stirs in motor and the gap between change speed gear box and cylinder, or hook top to cylinder bottom, withstand on drum shell; One of them damage in motor, change speed gear box or hook can be made time serious, or fall down from high-altitude, jeopardize the personal safety around electric block, therefore there is potential safety hazard.
Summary of the invention
The purpose of this utility model is for above-mentioned deficiency, and the one proposed does not need rope winding jib spacing to control, even if occur that grain is hung and run to askew the skewing of steel rope, also can avoid the Motor Driven Elevating Calabash inhibiting device damaging motor and change speed gear box.
Technical solution of the present utility model is: the shell below the cylinder of electric block is fixed with four slide plates, wherein two slide plates are fixed on the two-end part of cylinder, two other slide plate is fixed on the middle part of cylinder, four slide plates are fixed with limit switch respectively, and the small slide plate on limit switch is vertical with the axis of cylinder to be arranged.
One end of described in technical solution of the present utility model four slide plate is respectively equipped with chute, and the direction of this chute is vertical with the axis of cylinder to be arranged, and slide plate is fixed on the shell below cylinder by the chute screw rod on it.
One end head of the small slide plate described in technical solution of the present utility model is a circular arc.
The shell edge of the cylinder both sides of the electric block described in technical solution of the present utility model is fixed with circular arc baffle plate respectively, and circular arc baffle plate is connected on the shell edge of cylinder both sides by screw rod.
The round gusset of the drum shell both sides of the electric block described in technical solution of the present utility model is fixed with hoist ceiling crane support.
The utility model is after lifting limit switch has been installed in the below of cylinder, do not need rope winding jib spacing to control, steel rope itself can run according to the track on cylinder, when occur steel rope askew skew hang and run grain time, limit switch of the present utility model will be encountered, make motor power-off, thus can avoid damaging motor and change speed gear box, ensure that the personal safety around electric block, eliminate potential safety hazard; It is low that the utility model and prior art compare cost, and installation and maintenance are convenient; Applicant is to the utility model through practice after a while, and effect is fine.

Detailed description of the invention
As shown in Fig. 1,2,3,4,5, the gusset of drum shell is fixed with the small gusset 3,4 having through hole, for the lifting of electric block, motor 2 and change speed gear box 1 are located at the both sides of cylinder respectively; Shell square is under the rollers fixed with four slide plates 7, wherein two slide plates 7 are fixed on the two-end part of cylinder, two other slide plate 7 is fixed on the middle part of cylinder, one end of these four slide plates 7 is respectively equipped with chute, when four slide plates 7 are fixed on the shell below cylinder, the direction of this chute is vertical with the axis of cylinder to be arranged, and slide plate 7 is fixed on the shell below cylinder by the chute screw rod on it, and slide plate 7 can moving radially along cylinder; Four limit switches 8 are fixed on respectively by screw on the other end of slide plate 7, chute on slide plate 7 can be used for adjusting the distance of steel rope and limit switch 8, respectively with the small slide plate 10 that control limit switch 8 is opened and closed on four limit switches 8, small slide plate 10 on limit switch 8 is vertical with the axis of cylinder to be arranged, small slide plate 10 be by its one end with chute be screwed on limit switch 8, the position of limit switch 8 can be adjusted; The other end head of small slide plate 10 is a circular arc, can ensure when steel rope encounters the small slide plate 10 on limit switch 8, limit switch 8 can cut off the power supply of motor 2 in time, avoid steel rope to slip from the small slide plate 10 of limit switch 8 in advance, and make the power supply of motor 2 not cut off and have an accident; The shell edge of cylinder both sides is fixed with circular arc baffle plate 5,6 respectively, circular arc baffle plate 5,6 is connected on the shell edge of cylinder both sides by screw rod, the effect of circular arc baffle plate 5,6 is, if when the limit switch 8 at cylinder two ends breaks down, steel rope can be lived by shelves, in the gap avoiding steel rope to involve on motor 2 and change speed gear box 1 limit; The round gusset of drum shell both sides is fixed with hoist ceiling crane support 9, and hoist ceiling crane support 9 is welded on the round gusset of drum shell both sides, can ensure stablizing when hoist ceiling crane is placed, and protect the safety of four limit switches 8 below cylinder.
Principle of work: two limit switches 8 being fixed on cylinder two ends control the decline of hook, two limit switches 8 be fixed in the middle of cylinder control the rising of hook; When hoist ceiling crane hook declines, on cylinder, two steel ropes move to motor 2 or change speed gear box 1, time bottom fast arrival, steel rope moves on the two edges of cylinder, steel rope encounters the small slide plate 10 on cylinder both sides limit switch 8, and after small slide plate 10 moves into place, any one limit switch 8 first puts in place, motor 2 power-off that limit switch 8 can be made to control, hook stops declining; When hook rises, two steel ropes are mobile in the middle of cylinder, when arriving below cylinder, steel rope encounters the small slide plate 10 on the limit switch 8 in the middle of cylinder, after small slide plate 10 moves into place, any one limit switch 8 first puts in place, motor 2 power-off that limit switch 8 can be made to control, and hook stops rising; Two limit switches 8 controlling to rise and decline are in order to double insurance, if one of them breaks down, another can also normally work.
