Abstract

An underground vertical hinged automatic door unit device overcomes the problems that a conventional underground vertical hinged door unit has no waterproof measures and adopts an alternating current brush motor, so that the size is larger and the use is limited. The underground vertical hinged automatic door unit device is characterized in that a synchronous belt is installed on a belt pulley of an output shaft of a brushless motor and a belt pulley of an input shaft of a speed reducer; the brushless motor, the speed reducer and the synchronous belt are completely sealed in a casing made of aluminum through an upper cover plate; and a water-proof sealing component is installed on the output shaft of the speed reducer. Compared with the prior art, the underground vertical hinged automatic door unit device has moderate size, can be used indoors so as to replace a traditional floor spring, and can also be used outdoors; the perfect waterproof maintenance-free design enables the underground vertical hinged automatic door unit device to operate normally even if the underground vertical hinged automatic door unit device is soaked in water for a long time; the synchronous belt is adopted for flexible transmission, so that noise is reduced to the utmost extent; and the brushless motor is adopted, so that the service life of the unit is prolonged, and the design and application range can be widened.

Description

Buried vertical hinged automatic door set

Technical field

The utility model belongs to the automatic door technical field, particularly a kind of buried vertical hinged automatic door set.

Background technology

Buried vertical hinged door unit of the prior art needs drainage trenching or negative well owing to there is not waterproof measure during installation; Because what adopt is to exchange brush motor, brush weares and teares easily, and be restricted service time, and alternating current generator electric leakage easily causes security incident, and volume is bigger, can only be used for outdoorly, has limited the scope that use in market.

Summary of the invention

Problem to be solved in the utility model is, overcomes the deficiencies in the prior art part, provides to have waterproof measure the unrestricted a kind of buried vertical hinged automatic door set of the scope of application.

The technical solution adopted in the utility model comprises brushless electric machine, reductor, band synchronously is installed on the belt pulley of the belt pulley of brushless electric machine output shaft and reductor power shaft, with upper cover plate brushless electric machine, reductor and synchronous band are sealed in the housing the inside fully, the waterproof sealing assembly is housed on speed reducer output shaft.

Described waterproof sealing assembly is made up of mechanical sealing member, the screw that plays the gland effect and dust cap.

Described mechanical sealing member is the notch cuttype axle sleeve, on notch cuttype axle sleeve inner hole wall, be processed with the first O-ring seal groove and the 3rd O-ring seal groove that are used to install O-ring seal, be processed with the second O-ring seal groove that is used to install O-ring seal in notch cuttype axle sleeve right-hand member positioning step left side, notch cuttype axle sleeve left end minor diameter axle sleeve end face is processed as regular hexagon axle sleeve end face, and notch cuttype axle sleeve outer rim is processed with the connecting thread that is connected with screw.

Compared with the prior art, the utility model is simple in structure, volume is moderate and easy for installation, promptly can be used for indoor replacement spring traditionally, can be used for outdoor again, the non-maintaining design of waterproof that the utility model is perfect, can operate as normal even if this practicality is newly ducked in drink also for a long time, be with flexible transmission synchronously owing to adopt, amplitude peak has reduced noise, owing to use brushless electric machine, improved unit application life.

The specific embodiment

Next step provides the specific embodiment of the present utility model in conjunction with the accompanying drawings.

As shown in Figure 1, the technical solution adopted in the utility model comprises brushless electric machine 1, reductor 3, on the belt pulley of the belt pulley of brushless electric machine 1 output shaft and reductor 3 power shafts, install and be with 2 synchronously, described reductor 3 is installed on the base of the housing of making of aluminium sheet 6 by screw, the upper cover plate of making of corrosion resistant plate 5 is with brushless electric machine 1, reductor 3 and be with 2 to be sealed in housing 6 the insides fully synchronously, and the waterproof sealing assembly is housed on speed reducer output shaft 7.

Described waterproof sealing assembly is by mechanical sealing member 4-1, the screw 4-3 and the dust cap 4-2 that play the gland effect form, described mechanical sealing member 4-1 is the notch cuttype axle sleeve, on notch cuttype axle sleeve inner hole wall, be processed with the first O-ring seal groove 4-1-1 and the 3rd O-ring seal groove 4-1-3 that are used to install O-ring seal, be processed with the second O-ring seal groove 4-1-2 that is used to install O-ring seal in notch cuttype axle sleeve right-hand member positioning step left side, notch cuttype axle sleeve left end minor diameter axle sleeve end face is processed as regular hexagon axle sleeve end face 4-1-4, and notch cuttype axle sleeve outer rim is processed with the connecting thread 4-1-5 that is connected with the screw 4-3 that plays the gland effect.

Described brushless electric machine 1 adopts the direct current three-phase brushless motor, and be equipped with by the Hall element magnetic encoder inside, can detect position and speed that speed reducer output shaft 7 rotates, forms closed hoop control; With being with 2 to connect brushless electric machine 1 and reductor 3 synchronously, owing to be with 2 flexible transmissions synchronously, can reduce mechanical shock to greatest extent, reached the effect of amplitude peak reduction noise, be tightened on by the screw that plays the gland effect on the connecting thread of notch cuttype axle sleeve outer rim, the notch cuttype axle sleeve can be fixed on the speed reducer output shaft 7, add a cover dust cap 4-2 again, can make the housing 6 inner spaces that form a complete closed, at the first O-ring seal groove 4-1-1, O-ring seal is installed in the middle of the second O-ring seal groove 4-1-2 and the 3rd O-ring seal groove 4-1-3, by the sealing of three-layer sealed cushion rubber, can prevent fully that sealing or other foreign matters enter enclosure interior and influence machine operation.
