Abstract
A special multi-unit drum winch belongs to the technical field of hoisting machinery. The winch comprises a motor, a coupling, a speed reducer, a drum and a braking device, wherein the motor is connected to the input end of the speed reducer through the coupling, the output of the speed reducer is connected to a drum shaft and the braking device is arranged on the drum. The utility model has the improvement that the drum is divided into at least three units with equal volume by a fixed separation disk on the same working diameter. As a result, each unit can be wound by steel wire ropes of the same length, and a plurality of steel wire ropes which are wound on the drum carry out synchronous retraction and release in the form of identical length in the same work cycle; thereby, the requirement that an overhaul work platform of a boiler furnace, which is arranged at the other connecting end of a steel wire rope, is pulled to rise or fall stably can be satisfied. In the process, the splicing of the steel wire ropes is not required and mutual winding and irregularity can not occur for the steel wire ropes.
Description
Technical field
The utility model relates to a kind of cylinder winch, and especially a kind of multiple-unit cylinder winch that is applicable to occasions such as power plant boiler burner hearth service work platform belongs to the elevator machinery technical field.
Background technology
Understand according to the applicant, for a long time, owing to there is not suitable weight-lifting equipment, the raw mode of setting up wooden scaffold is continued to use in the work of power plant burner hearth maintenance and so on always, time-consuming, operator's labour intensity is very big, and the period of inspection and repair is long, especially when the maintenance of the mistake heat shielding district of 30 meters height, the transportation of material is difficulty very.After construction finishes,, can only burn, cause the very big waste of goods and materials at the burner hearth internal combustion because scaffold can't be removed.
Existing winch is connected with reductor by coupler by electrical motor usually, and drives cylinder by reductor, and drg is housed on the cylinder.The cylinder of the existing winch of this class can't satisfy the needs that many steel ropes twine synchronously, therefore can not be in applications such as power plant light aluminum alloy boiler hearth overhaulings.In addition, though the type of drg has forms such as magnet stopper, parking brake drg, hydraulic push-rod brake, fail to organically combine.
Summary of the invention
The purpose of this utility model is: propose a kind of simple in structure, multiple-unit special cylinder winch that can twine simultaneously many steel ropes synchronously, thereby satisfy the needs of boiler hearth overhauling, fundamentally alleviate working strength of workers, shorten the service work cycle of boiler hearth overhauling and so on work, save financial resource.
In order to reach above purpose, multiple-unit special cylinder winch of the present utility model comprises electrical motor (1), coupler (2), reductor (4), cylinder (5) and brake equipment, described electrical motor (1) is connected with the input end of reductor (4) by coupler (2), the output of described reductor (4) is connected with cylinder (5) axle, described cylinder is equipped with brake equipment on (5), and its improvements are: be separated into the cell that at least three volumes equate by fixing separator on the identical working diameter of described cylinder (5).The quantity of cell can be three to ten selections as required, and is the most frequently used with six.
Like this, each cell can the identical steel rope of coiling length, and in same cycle of operations, many steel ropes that are wrapped on the cylinder are done synchronous folding and unfolding, length is identical, thereby can satisfy the steady needs that rise or descend of boiler hearth overhauling workplatform of another coupling end of pulling steel rope.In this process, do not need wire rope splicing, the mutual winding of steel rope and uneven can not appear.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
The specific embodiment
Embodiment one
Present embodiment is a kind of multiple-unit special cylinder winch that is used for light aluminum alloy boiler hearth overhauling workplatform, as shown in Figure 1, primary member has electrical motor 1, coupler 2, magnet stopper 3, reductor 4, cylinder 5, stroke limit brake switch 6, parking brake drg 7, hydraulic push-rod brake 8.Wherein electrical motor 1 is connected with the input end of reductor 4 by coupler 2, and the output of reductor 4 is connected with 5 on cylinder.Be separated into the cell that six volumes equate by fixing separator on the cylinder 5 identical working diameters.
The mouth of electrical motor 1 is equipped with magnet stopper 3, and an end of cylinder 5 is equipped with parking brake drg 7 and hydraulic push-rod brake 8 simultaneously.Magnet stopper 3 and hydraulic push-rod brake 8 all are controlled by stroke limit brake switch 6.Therefore braking is very reliable.
During work, coupler 2 connects electrical motor 1 and reductor 3, after electrical motor 1 energising, the mouth output low speed power producer of reductor 3, drive cylinder 5 low speed rotation, cylinder 5 is provided with six cells on same working diameter, and cw twines the steel rope of six roots of sensation equal length simultaneously.Like this, the six roots of sensation steel rope that is wrapped in 5 six cells of cylinder is respectively done synchronous folding and unfolding, and make the folding and unfolding length of six roots of sensation steel rope identical, the other end of six roots of sensation steel rope connects light aluminum alloy boiler hearth overhauling workplatform respectively, thereby pulling light aluminum alloy boiler hearth overhauling workplatform steadily rises or descends.
Stop mechanism draws back parking brake drg 7 before motor start-up work, when electrical motor quits work, drop into parking brake drg 7, glides under overweight state to prevent light aluminum alloy boiler hearth overhauling workplatform.When electrical motor powers up work, magnet stopper 3 and hydraulic push-rod brake 8 power up action synchronously, break away from braking mode, when in electrical motor 1 outage or the working process during power down suddenly, magnet stopper 3 and hydraulic push-rod brake 8 be instantaneous dead electricity simultaneously, the locking drg stops the rotation electrical motor 1 and cylinder 5 simultaneously.In the course of the work, stroke limit brake switch 6 is made isometric exercise in proportion with cylinder 5, when cylinder 5 moves to effective forced stroke of setting, stroke limit brake switch 6 produces action, make electrical motor 1 dead electricity, magnet stopper 3 and hydraulic push-rod brake 8 be instantaneous dead electricity simultaneously, the locking drg, and electrical motor 1 and cylinder 5 stop operating.
The multiple-unit special cylinder winch that experimental results show that present embodiment is reasonable in design, and manual dexterity is reliable, and stop mechanism has the quadruple defencive function.In shutting down working process, the parking brake drg is arranged, when parking maintenance or the load of bench board during greater than rated load, nominal load, the parking brake drg can guarantee cylinder not can because of the draw of steel rope to lower slider; When powering up work, the magnet stopper brake motor, the hydraulic push-rod brake brake drum, instantaneous the finishing of braking demonstrate,proved in two kinds of brakings simultaneously; The stroke limit brake switch is synchronoused working with cylinder, action in the cylinder efficient working range of setting, when motion exceeds efficient working range, automatic train stop.Cylinder with six cells, the effective volume of each cell is identical, and the length of steel wire rope of winding is identical, like this, has guaranteed that in the same cycle of operations, the movement length of six roots of sensation steel rope is identical, has avoided the mutual winding of steel rope and uneven.
