Description
Technical field
The utility model belongs to auxiliary device field, colliery, particularly a kind of motor blower fan special demounting device.
Background technology
In coal mining enterprise's production process, due to the feature of coal production, all need powerful motor as power on many devices, the working environment of these motors and job site are all more special, sometimes need to carry out in working site when keeping in repair, because the power of motor is larger, volume and weight is also simultaneously larger, some part is needed to pull down during maintenance, due to working environment restriction, general equipment can not be adopted to carry out this work, cause difficulty just to the dismounting of the part of heavy-duty motor, the particularly dismounting of the fan blade of motor, because the blade construction of large multiple fan blade is weaker, adopt general instrument to carry out dismantling such as crowbar and often damage fan blade, and other instruments have and can not effectively be pulled down easily by overall fan blade, very large difficulty is caused to maintenance work.
Summary of the invention
For the problem of existing coal mining enterprise large power, electrically machine blade dismounting difficulty, the utility model proposes a kind of motor blower fan special demounting device, it is characterized in that: comprise fixed head, fastening bolt, stud, handle; Described fixed head is tabular, is provided with the hole corresponding with the fastening screw pit on motor blower fan, and middle part is provided with the female hole of band; Described fastening bolt is arranged on fixed head, the specification of its screw thread specification and quantity and position and the screwed hole on fan blade and quantity and position corresponding; Described stud is arranged in the middle part screwed hole of fixed head, and one end contacts with motor shaft, and the other end is provided with handle; Described handle is arranged on stud and is positioned at outside one end.
Beneficial effect
The beneficial effects of the utility model are, can the fan blade of easy removal heavy-duty motor, use manpower and material resources sparingly, increase work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model
1. fixed head, 2. fastening bolt, 3. stud, 4. handle.
Detailed description of the invention
In order to further illustrate the technical solution of the utility model, existing accompanying drawings detailed description of the invention of the present utility model, as Fig. 1, the steel plate of thickness 16 millimeters is selected in this example, be cut to the shape similar to fan blade shape, at its periphery, the hole corresponding with the retaining thread hole on fan blade is set, illustrate for the fan blade of 4 fixing holes in this example, heart position arranges screwed hole wherein, and the screwed hole in this example selects the common internal thread of the closely-pitched of M32X2, also trapezoidal thread can be selected, using this part as fixed head 1, retaining thread hole in this example on a fan blade is M12 is example, and fixed head 1 makes the hole of 4 diameters 14 millimeters, and position is corresponding with the screwed hole on fan blade, installs 4 outer-hexagonal bolts meeting the M12 of national standard as fastening bolt 2 in 4 holes, select the round steel of diameter 32 millimeters, length 400 millimeters, at its outside external screw thread making M32X2, two ends respectively have diameter be 28 millimeters without thread segment, its length is 60 millimeters, by its two ends through Quenching Treatment to improve its hardness, the through hole of diameter 14 millimeters is at one end set with central axis, above as stud 3, select the round steel of diameter 12 mm length 400 millimeters as handle 4, penetrated in the hole of stud 3 one end, just complete enforcement of the present utility model, during application, by vertical with motor shaft for fixed head 1, fastening bolt 2 on fixed head 1 and the retaining thread hole on fan blade to be removed to be screwed and fastening, move handle 4, stud 3 is rotated, stud 3 moves along the endoporus on fixed head 1 to motor shaft direction, until behind the end of contact motor shaft, continue to move handle 4, stud 3 continues the end holding out against motor shaft, now due to the strength of screw thread, fixed head 1 pulls fastening bolt 2 thus drives fan blade to move to the outer end of motor shaft, continue to move handle 4, stud 3 just drives fixed head 1 to continue motion until pulled down from motor shaft by fan blade, owing to have employed fastening bolt 2, not fragile motor blower fan, because stud have employed fine thread, spinning force reduction is made namely to dismantle laborsaving, owing to have employed handle 4, make more convenient to operate, because stud 3 two ends are through Quenching Treatment, make stud 3 more durable.
