Abstract
The utility model discloses a support device of a subway fan motor. A flange is fixedly arranged on the end wall of an inner support tube, the inner support tube wall at the upper end of the motor is short, the inner support tube wall at the lower end of the motor is long, most parts of the upper end of the motor are exposed out of the inner support tube wall positioned at the upper end of the motor, the inner support tube is fixedly arranged on the inner wall of an outer support tube through connecting plates, the connecting plates are uniformly fixed on the outer wall of the inner support tube and have the same length as the inner support tube positioned at the part, installing holes and accommodating holes are respectively formed in the inner support tube wall and the connecting plates corresponding to the hanging ring positions of the lower end of the motor and the symmetrical positions positioned at the two ends of a hanging ring, screw bolts are fixedly arranged in the installing holes formed in the inner support tube wall, are fixed at the lower end of the motor, and are positioned in the accommodating holes of the connecting plates. When the support device of the subway fan motor is adopted, the support intensity is high, the motor vibration is reduced, the flow guide effect is also realized, the heat radiation effect of the motor is good, the efficiency of the subway fan is improved, and the energy consumption of the subway fan is reduced.
Description
Technical field
The utility model relates to a kind of support device of underground fan motor.
Background technique
Along with the fast development in city, traffic above-ground far can not meet the needs of people's trip, and overburdening phenomenon has appearred in most domestic urban transportation, has brought great inconvenience to people's trip.Government greatly develops traffic route for solving urban traffic blocking problem, but all undesirable.From western countries, development subway transportation makes it to form networking and can effectively alleviate the problem that traffic above-ground is blocked up.Subway is the traffic tool that travel at Urban underground Tunnel, in order to ensure passenger and the personnel's that wait life and the safety of property, ventilation equipment-subway axial-flow blower is installed in the tunnel that need to exercise at subway and waiting station platform place, the needs that ensure that for supplementing ozone people breathe, and in the situation that producing unexpected fire, poisonous, harmful gas are discharged to tunnel, thereby ensure to greatest extent passenger's safety trip.
Along with the development of subway transportation networking, the demand of subway axial-flow blower can significantly increase.Existing underground fan motor is generally selected B3 or B35 structure, installation form is that lower margin is installed, motor supporting device is generally horizontal support form, motor is fixed on inner tube wall, inner core is fixed on transverse slat by lower margin, transverse slat is fixed on outer tube wall by support, and the lower end of urceolus fixes on the ground by lower margin, as shown in Figure 1.This kind of support device air current flow resistance is large, and underground fan efficiency is low, and power consumption is large.
Model utility content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, a kind of support device of underground fan motor is provided, adopt this support device that underground fan motor is installed, not only support strength is high for it, reduced fan vibration, also played the effect of water conservancy diversion, motor radiating is effective, improve the efficiency of underground fan, reduced the energy consumption of underground fan.
For achieving the above object, technical solution of the present utility model is: a kind of support device of underground fan motor, and it comprises the connecting plate that outer support cylinder, inner support cylinder, flange plate and water conservancy diversion direction are identical with underground fan guide plate water conservancy diversion direction; Flange plate is fixed on the end wall of inner support cylinder; Inner support barrel in motor upper end is short, and the inner support barrel of lower end is long, and the major part of motor upper end is exposed the inner support barrel of motor upper end; Inner support cylinder is fixed on outer support cylinder inwall by being evenly fixed on the identical connecting plate of inner support tube length degree on its outer wall and this place; Having mounting hole and receiving bore with the suspension ring position of motor lower end with being positioned on the corresponding inner support barrel of two ends, suspension ring position symmetrical position He on connecting plate; Be bolted in the mounting hole on inner support barrel, be fixed on the lower end of motor, be positioned at the receiving bore of connecting plate.
The utility model is played motor support by bolt, make to form air channel between motor and inner support cylinder, and the major part of motor upper end exposes the inner support barrel of motor upper end, makes motor have good thermal diffusivity, has improved efficiency and the life-span of motor.Connecting plate of the present utility model not only plays the effect of stiffening rib, and the air entering in inside and outside supporting drum is played to guide functions, not only reduce air current flow resistance, and made the more unobstructed and rule of air current flow, greatly improved the efficiency of underground fan motor.Constant intensity of the present utility model is high, has reduced fan vibration, and then has improved fan efficiency.The utility model makes underground fan reach country-level energy consumption standard.
