Description
Technical Field
The utility model relates to a motor, especially a construction elevator is with lifting machine motor rational in infrastructure, easy to assemble, dismantlement.
Background
The construction elevator is also called construction elevator for building, it is a manned goods-carrying construction machine frequently used in building, its riding is comfortable and safe due to its unique box body structure, the construction elevator is usually matched with tower crane in the field, its general load is 1-3 tons, and its running speed is 1-60M/min. The main transmission device of the construction elevator is a hoisting machine motor.
At present, need adjust the stopper clearance when maintaining the lifting machine, because motor fan housing mounting hole is traditional bolted connection hole, need lift the bolt of fixed fan housing off completely and just can take off the fan housing, the dismantlement speed is slow, the operation is inconvenient, because of dismantling on the lift simultaneously, causes the bolt to lose very easily, also makes the bolt drop from the eminence easily and produces the potential safety hazard.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a construction elevator is with lifting machine motor rational in infrastructure is provided, easy to assemble, dismantlement.
In order to solve the technical problem, the utility model discloses a lifting machine motor convenient to dismantle, including the casing, be located the stator core with winding in the casing, be located the rotor that is supported by the motor shaft in the stator core, the front end of casing, rear end are connected with front end housing, rear end cap respectively, and the front end, the rear end of motor shaft wear out from front end housing, rear end cap respectively, be fixed with the fan on the rear end cap, still be fixed with the fan housing that covers on the fan on the rear end cap, be equipped with a plurality of mounting holes on the fan housing, the mounting hole includes screw, circumference slot hole, axial slot hole, and circumference slot hole link up with last screw, axial slot hole one end link up with circumference slot hole, and the other end link up the uncovered edge of fan housing, and the hookup location of circumference slot hole and axial slot hole is located same one side of last screw, is equipped with screw complex lower screw on the rear end cap terminal surface, and fan housing and rear end cap are through passing last screw, And fastening the bolt of the lower screw hole.
After adopting such structure, when maintaining the regulation stopper clearance to the lifting machine motor, can take off the motor fan housing under the condition that the bolt of fixing the fan housing is not lifted off completely, easy operation, dismantlement are convenient quick, have avoided the inconvenience that the bolt lost and the potential safety hazard that the bolt dropped the production from the eminence.

FIG. 1 is a block diagram of the present invention;
FIG. 2 is a structural diagram of the fan housing of the present invention;
FIG. 3 is a structural diagram of the rear end cap of the present invention;
fig. 4 is an enlarged view of portion i of fig. 2.
Detailed Description
Shown by fig. 1 to 4, the utility model discloses a convenient to detach's lifting machine motor, including casing 1, locate the tape winding stator core 2 in the casing 1, be located the rotor 4 that is supported by motor shaft 3 in stator core 2. The front end and the rear end of the shell 1 are respectively connected with a front end cover 8 and a rear end cover 5, the front end head and the rear end head of the motor rotating shaft 3 respectively penetrate out of the front end cover 8 and the rear end cover 5, a fan 6 is fixed on the rear end head, and a fan cover 7 covering the fan 6 is further fixed on the rear end cover 5. The fan housing 7 is cylindrical with an open end, and four mounting holes 10 are circumferentially and uniformly distributed on one side of the open end at intervals.
The mounting hole 10 is composed of an upper screw hole 11, a circumferential long hole 12, and an axial long hole 13, the circumferential long hole 12 is communicated with the upper screw hole 11, one end of the axial long hole 13 is communicated with the circumferential long hole 12, and the other end is communicated with the opening edge of the fan cover 1. The radius of the upper screw hole 11 is the same as the width of the circumferential long hole 12 and the width of the axial long hole 13, the circumferential long hole 12 is smoothly connected with the upper screw hole 11 and the axial long hole 13, and the connection position of the circumferential long hole 12 and the axial long hole 13 is positioned on the same side of the upper screw hole 11. The end face of the rear end cover 5 is provided with a lower screw hole 14 matched with the upper screw hole 11, the inner parts of the upper screw hole 11 and the lower screw hole 14 are provided with inner threads matched with a bolt 15, and the motor fan cover 7 and the rear end cover 5 are fastened through the bolt 15 penetrating through the upper screw hole 11 and the lower screw hole 14.
When maintaining adjustment brake clearance to lifting motor for construction elevator, no longer need lift bolt 15 of fixed fan housing 7 off completely, but only need loosen bolt 15 to the take the altitude after, with fan housing 7 along the direction rotation of circumference slot hole 12 to the hookup location of circumference slot hole 12 and axial slot hole 13, can part motor fan housing 7 and fixing bolt 15 along the direction of axial slot hole 13 afterwards, fan housing 7 can directly be plucked, easy operation is quick, the potential safety hazard of the bolt loss and the bolt production of dropping from the eminence when having avoided the operation simultaneously. And when motor fan housing 7 needs to be installed, can be in advance with the bolt earlier fixed to the lower screw 14 on rear end housing 5 in, push motor fan housing 7 along axial slot hole 13 inwards to the hookup location of circumference slot hole 12 and axial slot hole 13, then rotate along circumference slot hole 12 and align to the last screw 11 that makes motor fan housing 7 and rear end housing 5's lower screw 14, screw up bolt 15 at last and can accomplish the installation, installation easy operation, convenient quick.
