Abstract
The utility model discloses a motor door rolling machine. The utility model adopts a self-locking decelerator and a special motor, besides, the utility model is not needed to be provided with a brake apparatus and heat dissipation systems such as a motor fan housing, a fan, etc., so the structure of the complete machine of the utility model is simple and compact, and the weight is lightened. The utility model is provided with a retainer and a hand gear which has the breaking energization interlocking action, and therefore, the utility model is convenient in operation and simple in installation.
Description
The utility model relates to a kind of electric opening, closes the machine of rolling door.
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 does not have 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 the complete machine structure heaviness.
The purpose of this utility model is the deficiency that overcomes existing technology, but a kind of reducer self-locking is provided, and has stop, and the lighter electric door-rolling machine of weight simple in structure.
The purpose of this utility model is achieved in that design one cover self-locking worm type of reduction gearing, and the two ends of its output shaft drive stop respectively and are used to drive the operation up and down of rolling door; The motor special input connects one and manually installs, and output links to each other with the worm screw of reducer, constitutes the utility model electric roll-up door mechanism.
The described stop of the utility model electric roll-up door mechanism can connect with the worm gear output shaft by chain gear transmission is secondary, leading screw, slide block and limit switch are housed in the housing of stop, control the running of motor by adjusting stop, thereby reach spacing to lower dead center on the rolling door.
The described hand gear of the utility model electric roll-up door mechanism comprises hand chain wheel, manual chain, interlocking switch and switch briquetting, hand chain wheel is installed on the power shaft of motor, interlocking switch and switch briquetting are arranged on the hand chain wheel below, when manual chain places on the switch press plate, 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.
The utility model 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.
The utility model electric roll-up door mechanism adopts self-locking reducer and motor special, 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 in-local convenient, installs and uses simple.
Reaching embodiment in conjunction with the accompanying drawings is further described the utility model:
Accompanying drawing 1, the utility model example structure schematic diagram:
Accompanying drawing 2, the utility model embodiment A-A sectional view;
Shown in accompanying drawing 1, accompanying drawing 2, the hand gear of electric roll-up door mechanism (1) is installed in the front end of motor (2), the output shaft of motor (2) connects with the worm screw (31) of worm reducer (3), one end of worm gear (32) output shaft (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 of electric roll-up door mechanism (1) comprises hand chain wheel (11), manual chain (12), interlocking switch (14) and switch briquetting (13), 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) below.When manual chain (12) places switch briquetting (13) to go up, interlocking switch (14) is in normally closed, starter motor (2) running, motor (2) drives worm reducer (3) running, 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) is gone up at screw mandrel (52) and moved; Simultaneously, the other end of worm gear (32) output shaft (33) drives rolling door by a minor sprocket; When slide block (53) is run into limit switch (54), motor (2) outage shuts 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) outage; Spur manual chain (12), can drive motor (2) thus rotor rotation drive whole device.
Claims (4)
1, a kind of electric roll-up door mechanism, comprise members such as motor, reducer, it is characterized in that: reducer is the self-locking worm type of reduction gearing, the two ends of its output shaft drive stop respectively and are used to drive rolling door, the input of motor special connects one and manually installs, and the worm screw of output and reducer links.
2, electric roll-up door mechanism according to claim 1 is characterized in that: described stop can connect with the worm gear output shaft by chain gear transmission is secondary, and leading screw, slide block and limit switch are housed in the housing of stop.
