Description

Technical Field

The driving principle of the elevator is to drive the wheel set through the electric motor, and bypass the reducer to make the wheel set directly drive the elevator car to move. The rotation of the motor-driven wheel set causes the suspended counterweight to bypass the pulley and move in the opposite direction, reducing the weight of the people or objects carried by the elevator, so that the elevator can rise and fall smoothly. The existing elevator drive host has an excessively high internal temperature due to the continuous use of the motor during use, which makes the motor's operating effect worse and affects the motor's service life. For this reason, we propose an elevator drive host with intelligent ventilation function.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides an elevator drive protection device, comprising a protection cover 1, a protection mechanism 2 for protecting a driving member is arranged on the top of the protection cover 1, a ventilation mechanism 3 for dissipating heat from the driving member is arranged on the outside of the protection cover 1, and side plates 21 in the protection mechanism 2 are respectively fixedly mounted on the four sides of the top of the protection cover 1;

[0024] A cross bar 22 is fixedly installed on the inner side of the side plate 21, a spring 23 is welded to the outer side of the cross bar 22, a connecting sleeve 24 is welded to the inner end of the spring 23, a shielding component is arranged on the top of the connecting sleeve 24, the connecting sleeve 24 is slidably connected to the outer side of the cross bar 22, and an auxiliary component is arranged on the outer side of the connecting sleeve 24.

[0025] It is used to provide stable shielding and protection, and at the same time it can buffer the impact force generated when falling, so as to improve the protective effect.

[0026] like Figure 4 As shown, the shielding assembly includes a movable rod 27, which is rotatably connected to the top of the connecting sleeve 24. The top of the movable rod 27 is rotatably connected to a connecting block 28, and a top plate 29 is fixedly installed on the top of the connecting block 28. The movable rod 27 can be used to support the top plate 29, and the top plate 29 is used to provide direct force shielding protection.

[0027] like Figure 4As shown, the shielding assembly includes a connecting plate 25, which is fixedly mounted on the surface of the connecting sleeve 24. A damper 26 is fixedly mounted on the outer side of the connecting plate 25. The end of the damper 26 away from the connecting plate 25 is fixed to the side plate 21. The connecting plate 25 is convenient for connecting and supporting the damper 26. The damper 26 cooperates with the spring 23 to complete elastic damping and buffer force dissipation.

[0028] When protecting:

[0029] The state shown in the figure is the protection state. When it is subjected to impact force from above, it will directly fall on the top of the top plate 29, and the force will be borne by the top plate 29. When the top plate 29 is subjected to force, it will move directly downward. When the top plate 29 moves downward, it will press the cross-arranged movable rods 27 to rotate and produce an angle change. When the angle changes, it will directly push the movable rods 27 outward to push the connecting sleeve 24 to slide on the surface of the cross bar 22, so that the connecting sleeve 24 will directly push the spring 23 and the damper 26 to be compressed, and according to the elasticity and damping of the pressure, it will complete the buffering of the flushing and eliminate the impact of the force, thereby improving the protection effect.

[0030] Preferably, the ventilation mechanism 3 includes an exhaust component, an exhaust component and a shielding component.

[0032] like Figure 3 As shown, the exhaust assembly includes a first protective net 33, which is fixedly installed on the wall thickness on both sides of the top of the protective cover 1. Ventilation holes 34 are opened on the outside of the protective cover 1 to achieve ventilation of the top while preventing debris from entering therein.
