Abstract
The utility model provides a device for disassembling a hydraulic bracket of a suspended top beam. The device comprises a base, wherein a motor is fixedly arranged on the base; a speed changer is connected to an output shaft of the motor; an output shaft of the speed changer is connected with a fixed sleeve; a fixed rack is fixedly arranged at the other end of the base; coaxial fixed holes for penetration of an upright post of the hydraulic bracket are formed in the centers of the fixed sleeve and the fixed rack in an axial manner; the fixed sleeve is driven to run at a low speed through the motor while a guide sleeve and a connecting strip are unscrewed to draw out the connecting strip. Thus, the work efficiency is greatly improved, and the beating operation of a worker is also avoided. Therefore, the labor intensity of the worker is relieved.
Description
Technical field
The utility model relates to mining bracket field, is specifically related to a kind of for dismantling the device of hydraulic prop for moving suspended top beam.
Background technology
Hydraulic prop for moving suspended top beam is a kind of novel formula light hydraulic support that moves in vain between large-scale fully mechanized mining supporter and hydraulic prop.The advantage that it has been inherited fully mechanized mining supporter safety, can certainly move, have that adaptability is good, volume is little, the advantage such as lightweight, easy to operate, easy accessibility, applicable to the good working face of geological conditions, also can be used for roof cracking, floor are soft, tomography is many working face and the working face of high inclination-angle.Hydraulic prop for moving suspended top beam is mainly by left and right two back timbers of roof supporting arranged side by side, and the extensible canopy in back timber and jockey, under the effect of hydraulic jack, realize support mobile integrated, simplify work technique, raise labour efficiency, reduce labor intensity, improve working face security.
Due to subsurface environment humidity and air permeability poor, hydraulic prop for moving suspended top beam is after being used to complete the coal work of a working face, some seals and consumable accessory be as easy damage, needs to it, place under repair in time, in order to continuing to recycle.When repairing, be mainly that the connection strap between the column of hydraulic prop for moving suspended top beam and hydraulic cylinder is changed, and hydraulic jack inner seal ring is changed and cleaned.Between the fairlead of column and hydraulic cylinder, be to adopt Long Circle connection strap to be fixed, connection strap directly fits inside along circumferencial direction from an aperture of fairlead and cylinder body junction, thereby fairlead and cylinder body are linked together.But cannot extract out smoothly due to connection strap corrosion, for the old connection strap of dismantling, can only gently advise and beat fairlead with bell, by continuous vibrations, make connection strap loosening gradually, with clamping work, extract out at leisure again, remove a connection strap and need to spend 1-3 hour, its operating efficiency labour intensity low and workman is large.And connection strap because of unbalance stress also easy fracture in fairlead.
Utility model content
The utility model, for Problems Existing, provides a kind of and increases work efficiency and the object that alleviates hand labor intensity for dismantling the device of hydraulic prop for moving suspended top beam, reaching.
In order to achieve the above object, the utility model provides a kind of and comprises base for dismantling the device of hydraulic prop for moving suspended top beam, on described base, is installed with motor, and the output shaft of described motor is connected with speed changer, and the output shaft of described speed changer is connected with fixed cover; The other end of described base is installed with fixed mount; Described fixed cover with the central shaft of fixed mount to all offering for wearing the coaxial fixing hole of hydraulic support column.
Further, meet the requirement of connection strap intensity, and avoid breaking connection strap for the rotating speed of motor is reduced, the output shaft of described speed changer is connected with decelerator by shaft coupling, and the output shaft of described decelerator is connected with fixed cover.
Further, the fixing hole at described fixed cover center is circular port, and three fixedly the first bolts of use are evenly laid in its outside.
Further, the fixing hole at described fixed mount center is square opening, and three fixedly the second bolts of use are evenly laid in its outside.
On described base, be installed with holder, described holder is positioned at the fixing hole port of fixed cover.
First the piston end of hydraulic support column is penetrated from fixed mount central square fixing hole, until arrive in the central circular fixing hole of fixed cover, make its fairlead be positioned at the first bolt place of circular fixing hole, and the first bolt is carried out fastening; The end of hydraulic support column is positioned at the square fixing hole of fixed mount, with the second bolt, is fixed.Then with holder or artificial hand-held pliers, the connection strap termination that is positioned at fairlead and cylinder body interface place is clamped, open motor simultaneously, the rotating speed of motor is by passing through the further reduction of speed of decelerator again after the reduction of speed of gearbox, the speed that makes finally to output on fixed cover is uniform low speed, its speed is only 8 revs/min, thereby has guaranteed can not rupturing of connection strap.Fixed cover drives fairlead slowly to rotate to the contrary direction of connection strap winding direction, thereby unscrews connection strap, makes to be connected in rotary course and just can release like a cork.The time of removing a connection strap only needs 2-3 minute, has improved widely operating efficiency; And avoided workman to beat operation, thereby the workman's who alleviates labour intensity.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Fig. 2 is fixed cover side view of the present utility model;
Fig. 3 is fixed mount side view of the present utility model;
In figure: 1-base, 2-motor, 3-speed changer, 4-shaft coupling, 5-decelerator, 6-holder, 7-the first bolt, 8-fixed cover, 9-fixed mount, 10-the second bolt.
The specific embodiment
As shown in Figure 1, 2, 3, a kind of for dismantling the device of hydraulic prop for moving suspended top beam, comprise base 1, on described base 1, be installed with motor 2, the output shaft of described motor 2 is connected with speed changer 3, the output shaft of described speed changer 3 is connected with decelerator 5 by shaft coupling 4, and the output shaft of described decelerator 5 is connected with fixed cover 8.The other end of described base 1 is installed with fixed mount 9; Described fixed cover 8 with the central shaft of fixed mount 9 to all offering for wearing the coaxial fixing hole of hydraulic support column.The fixing hole at fixed cover 8 centers is circular port, and three fixedly the first bolts 7 of use are evenly laid in its outside; The fixing hole at fixed mount 9 centers is square opening, and three fixedly the second bolts 10 of use are evenly laid in its outside.
Further, be installed with holder 6 on described base, described holder 6 is positioned at the fixing hole port of fixed cover 8, for the bar that is clamped and connected, it is extracted out from fairlead.In practical operation, also available pliers replaces holder 6.
The piston end of hydraulic support column is penetrated from fixed mount central square fixing hole, make in its center fixing hole that is enclosed within fixed cover and fixed mount, and be fixed with bolt.By electric machine rotation, drive fixed cover to rotate, fixed cover drives the fairlead of hydraulic support column to carry out low speed, uniform rotation again, makes to connect to unscrew and to extract out with pliers or holder, thereby has improved widely operating efficiency, the workman's that alleviates labour intensity.
