Abstract
The utility model provides a reducer self-locking retaining door roller, which comprises a motor, a self-locking type worm wheel-worm reducer and a retainer, both ends of an output shaft of the self-locking type worm wheel-worm reducer respectively drive the retainer and a shutter door, the input end of the motor is connected with a manual unit, and the output end of the motor is connected with a worm of the reducer. Since the electric door roller adopts the self-locking type reducer and does not need a brake and heat-dissipating systems such as a motor fan housing and a fan, the whole structure is simple and compact, and the weight is reduced; and since the door roller is provided with the retainer and the manual unit with a power-off and power-on interlocking function, the door roller is convenient to operate and simple to mount and use.
Description
Technical field
The utility model relates to a kind of door-rolling machine, relates in particular to the spacing door-rolling machine of a kind of reducer self-locking.
Background technology
At present, some electric roll-up door mechanisms adopt gear type reducers to slow down, and reducer itself can not self-locking, a cover brake gear also need be set be used to pin the downslide that the rolling door dead weight causes, make the door-rolling machine complex structure, and weight is big; The electric roll-up door mechanism itself that also has is provided with stopping means, travel switch need be installed on the last lower dead center of door, uses complexity is installed; And most door-rolling machines adopt general-purpose machines to make heavy mouthful of complete machine structure.
Summary of the invention
In order to overcome above-mentioned defective, but the purpose of this utility model has provided a kind of reducer self-locking, has had stop and the lighter electric door-rolling machine of weight simple in structure.
For achieving the above object, technical solutions of the utility model are:
The spacing door-rolling machine of a kind of deceleration self-locking, comprise motor, self-locking worm type of reduction gearing and stop, the two ends of the output shaft of described self-locking worm type of reduction gearing drive stop respectively and drive rolling door, the input of described motor connects one and manually installs, and the output of motor is connected with the worm screw of reducer.
Described stop comprises leading screw, slide block and limit switch, and it is connected with the worm gear output shaft by chain gear transmission is secondary.
Described hand gear comprises hand chain wheel, manual chain, interlocking switch and switch briquetting, hand chain wheel is installed on the power shaft of motor, and interlocking switch and switch briquetting are arranged on the hand chain wheel below, when manual chain places on the switch briquetting, interlocking switch is in normally closed, electrical power; When manual chain places on the sprocket wheel, the switch briquetting is upspring, and interlocking switch often is in to be left, and the interlocking effect is played in the motor outage.
Described motor is a sheet steel enclosure, and inside is provided with thermal relay.
The usefulness of technique scheme is:
The electric roll-up door mechanism that this is novel adopts the self-locking reducer, does not need brake gear and cooling systems such as motor fan housing, fan are set, and makes complete machine structure simply compact, weight saving; The utility model is provided with stop and has the hand gear of switching on and off interlocking effect, makes that in-local is convenient, it is simple to install and use.
This novel electric roll-up door mechanism moves the characteristics of duty in short-term according to it; motor adopts sheet steel enclosure, cooling systems such as fan housing, fan is not set, but is provided with thermal relay in inside; make motor volume little, in light weight, and can protect motor normally to move effectively.
Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 2 is the routine A-A sectional view of the real trip of the utility model.
The specific embodiment
Embodiment
The spacing door-rolling machine of a kind of deceleration self-locking as shown in Figure 1 and Figure 2, comprise motor 2, worm reducer 3 and stop 5, the hand gear 1 of electric roll-up door mechanism is installed in the front end of motor 2, the output shaft of motor 2 is connected with the worm screw 31 of worm reducer 3, one end of worm gear 32 output shafts 33 is equipped with the chain wheel pair 4 that is used to drive stop 5, and the other end can pass through a chain wheel drive rolling door; Screw mandrel 52, slide block 53 and limit switch 54 are housed in the housing 51 of stop 5, control the running of motor 2, thereby reach spacing to lower dead center on the rolling door by adjusting stop 5.
The hand gear 1 of electric roll-up door mechanism comprises hand chain wheel 11, manual chain 12, interlocking switch 14 and switch briquetting 13, and hand chain wheel 11 is installed on the power shaft of motor 2, and interlocking switch 14 and switch briquetting 13 are arranged on hand chain wheel 11 belows.When manual chain 12 places on the switch briquetting 13, interlocking switch 14 is in normally closed, starter motor 2 runnings, motor 2 drives worm reducer 3 runnings, worm gear 32 drives chain gear transmission pair 4 by an end of output shaft 33, the screw mandrel 52 that the output wheel of chain gear transmission pair 4 drives stop 5 rotates, and slide block 53 moves on screw mandrel 52; Simultaneously, the other end of worm gear 32 output shafts 33 drives rolling door by a minor sprocket; When slide block 53 is run into limit switch 54, motor 2 outages shut down.
When needing use manual, manual chain 12 can be placed on the hand chain wheel 11, switch briquetting 13 is upspring, and interlocking switch 14 often is in to be left, and the interlocking effect is played in motor 2 outages; Spur manual chain 12, thereby the rotor rotation that can drive motor 2 drives whole device.
