Abstract
The utility model relates to an electric machine overhauling ladder, comprising at least two ridge frames, a pair of oblique beams connected with the ridge frames, a plurality of step tablets connected with the two oblique beams and a soleplate connected with the oblique beams and the ridge frames, wherein the ridge frame and the soleplate are approximately vertical, and an included angle between the oblique beams and the soleplate connected with the oblique beams is an acute angle. By using the electric machine overhauling ladder, stable supporting can be provided for an operating personnel alone, and accordingly, overhauling safety can be assured.
Description
Technical field
The utility model relates to a kind of machinery check and repair ladder, relates in particular to a kind of maintenance ladder that is used for large-size machine.
Background technology
Usually, there are some difficulties in the maintenance of the motor that is used for the coal mine fully-mechanized mining corollary equipment, because these motors generally all are heavy-duty motors, its volume and quality are all bigger, carry very difficult; On the other hand, the turn(a)round of equipment, is shorter, but that repair quality requires is strict, and with assurance equipment normal operation fault-free when the downhole production, this has brought pressure for machinery check and repair work.
Because the volume of the motor of maintenance is bigger, and it is highly also bigger, so that large-size machine of maintenance needed for 320 man-hours, particularly when motor extraction and assemble rotor, each safety custody people who all establishes sole duty, must with motor vertically on three supporters motor be supported on apart from the certain height of ground during work, the liftoff as required certain altitude of operating personnel overhauls some position of motor then.If use common ladder to finish service work, it need be rested on the fixed object, but, find to prop up by the certain constraint of ladder existence in real work, if it is ladder is rested on the wall, then far away excessively apart from motor; If ladder is rested on the motor, can bring potential safety hazard to the stable support of motor, and this type of is by also stable inadequately.
Therefore, there is potential safety hazard in this work, and assembles three supporters at every turn and expend man-hour, and operating efficiency is lower.
Therefore, be necessary to design a kind of new machinery check and repair ladder, to solve above-mentioned variety of issue.
The utility model content
The purpose of this utility model is to provide a kind of machinery check and repair ladder, by using this machinery check and repair ladder, can be separately for the operating personnel provide stable support, thus guaranteed maintenance safety.
To achieve these goals, the utility model is design like this: this machinery check and repair ladder comprises at least two ridge framves, a pair of cant beam that is connected with the ridge frame, connects some gangboards of two cant beams and the base plate that connects cant beam and ridge frame, wherein said ridge frame and base plate approximate vertical, and cant beam is an acute angle with angle between its base plate that is connected.
By using this machinery check and repair ladder, can be separately for the operating personnel provide stable support, thus guaranteed maintenance safety.
Description of drawings
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail, wherein:
Fig. 1 is the lateral view of machinery check and repair ladder of the present utility model.
Fig. 2 is the front view of machinery check and repair ladder of the present utility model.
The specific embodiment
See also Fig. 1 and Fig. 2, machinery check and repair ladder 1 of the present utility model is mainly used in maintenance large-size machine equipment.
This machinery check and repair ladder 1 comprises two ridge framves 10, a pair of cant beam that is parallel to each other 14 that is connected with ridge frame 10, the gangboard 16 that is connected two cant beams 14 and the base plate 12 that connects ridge frame 10 bottoms and cant beam 14 bottoms.
Wherein cant beam 14 is an acute angle with the angle of its base plate that is connected 10, and ridge frame 10 is approximately perpendicular to its base plate that connects 12, and the gangboard 16 of 14 of cant beams is parallel to each other to each other.
Be equipped with terraced wheel apparatus 18 on each base plate 12, each terraced wheel apparatus 18 comprises ladder wheel 180 and connecting axle 182.One end of described connecting axle 182 connects ladder wheel 180, and its other end and base plate 12 are hinged, this connecting axle 182 can be from a sideway swivel of base plate 12 to base plate 12 an other side, thereby drive the other side of ladder wheel 180 from a sideway swivel of base plate 12 to base plate 12.
For rotation at a lateral confinement system connecting axle 182 of base plate 12, on base plate 12, be provided with a stopper section 120, when connecting axle 182 from the other sideway swivel of base plate 12 during to this side, this connecting axle 182 is ended in described stopper section 120 by card, at this moment, the position of ladder wheel 180 is fit to it just and rolls on ground.With respect to stopper section 120, an other side of base plate 12 is an inclined-plane (a not label), and the setting on this inclined-plane is for convenience ladder wheel 180 to be contained in the relative other side in this base plate 12 and stopper section 120.
Overhaul terracedly 1 the time when application of motor, at first,, be limited to described stopper section 120 until connecting axle 182 with the other side of each terraced wheel apparatus 18 from the base plate 12 of a sideway swivel of base plate 12; Then, pushing motor maintenance ladder 1 is to corresponding maintenance position; Subsequently, each terraced wheel apparatus 18 is rotated to the side that it is provided with the inclined-plane, make ladder wheel 180 be contained in base plate 12 these sides, thereby make base plate 12 direct kiss the earths, to guarantee the stability of machinery check and repair ladder 1; At last, moving elevator maintenance ladder 1 then can repeat above-mentioned steps if desired.
The ridge frame 10 of this machinery check and repair ladder 1 and cant beam 14 adopt angle steel, and gangboard 16 then adopts decorative pattern iron plate, and base plate 12 adopts certain thickness steel plate.Therefore, the structure of this machinery check and repair ladder 1 is stronger, and its weight is also relatively large simultaneously, thereby has also strengthened the stability of its support.
By using this machinery check and repair ladder 1, can be separately for the operating personnel provide stable support, thus guaranteed operating personnel's personal safety, and also help increasing work efficiency.
