Abstract
The utility model belongs to a protection device for a hand wheel brake for a disc motor, and particularly relates to a protection device for a hand wheel brake of a disc brake asynchronous motor for the building cradle industry. As a hand wheel of the conventional three-phase disc brake asynchronous motor is exposed to a casing boss, the hand wheel is easy to be broken by falling building components and in brake failure to cause potential safety hazards to safety production when used on building site. A circular shield with the diameter of phi 161, which is rolled by a thick steel plate with the thickness of 5mm, is welded on a casing of the motor and protects the hand wheel.
Description
Technical field
The utility model belongs to three-phase disc type brake asynchronous motor handwheel brake protection device scope, particularly is used for a kind of disc type brake asynchronous motor handwheel brake protection device of building hanging basket industry
Background technology
Three-phase disc type brake asynchronous motor is mainly used in industries such as building hanging basket, forging machine tool, its handwheel material adopts allumen, be installed in casing boss place with M5 * 12 soket head cap screws, when using at building hanging basket, when building component comes off, easily its handwheel is smashed, cause three-phase disc type brake asynchronous motor hand brake malfunctioning, bring hidden danger to safety in production.So used for building hanging basket three-phase disc type brake asynchronous motor handwheel should be provided with protective device.To improve the safety of electric system, guarantee the equipment reliability service.
The utility model content
The purpose of this utility model is in order to solve in the background technology, and handwheel damaged when used in the construction site, can't discharge the braking system problem, so design a kind of handwheel brake protection device.This protective device is that the 5mm steel plate is wound into diameter phi 161 annular guard shields, and it highly is 55 ± 0.5mm, is welded on the casing with argon arc welding, and handwheel is installed on the boss of casing with M5 * 12 soket head cap screws.
Description of drawings
Fig. 1 is a handwheel brake protection device generalized section
(1) is the handwheel guard shield among the figure, and (2) are handwheel, and (3) are M5 * 12 soket head cap screws, and (4) are motor case
Embodiment
Handwheel guard shield (1) is wound into diameter phi 161 annulars with the 5mm steel plate as shown in Figure 1; be welded on the motor case (4) with argon arc welding; the guard shield height, plays a protective role to handwheel (2) and M5 * 12 soket head cap screws (3) when motor uses at building hanging basket greater than the handwheel height.
Operation principle of the present utility model is, by welding shield on the motor case, to handwheel be connected the handwheel screw and play a protective role, thereby improve the safety of the electric system of motor, guarantee the equipment reliability service.
This practicality is used for the building hanging basket industry, and the handwheel protective effect that it is good is played most important effect to building trade safety.
Claims (1)
1. the handwheel brake protection device is characterized by:
The 5mm steel plate is wound into diameter phi 161 annular guard shields (1), and it highly is 55 ± 0.5mm, is welded on the casing (4) with argon arc welding, and handwheel (2) is installed on the boss of casing (4) with M5 * 12 soket head cap screws (3).
