Description

A kind of quick door limiting device

Technical field

The utility model relates to rapid door technical field more particularly to a kind of quick door limiting devices.

Background technique

Rapid door is the abbreviation of " Rapid rolling door " and " quick rolling-door ", is the accessible isolating door of fast lifting, mainly Function is heat preservation, moisturizing, dust-proof, insect prevention, sound insulation etc., make workshop keep constant temperature, constant humidity, cleaning working environment.Suitable for food The fields such as product, medicine, electronics, rubber, chemical industry, automobile, weaving, logistics.

Currently, rapid door uses more and more extensive, limiter also more and more with the matching used limiter of rapid door Structure also become increasingly complex, manufacturing cost is high, repairs inconvenient.

Utility model content

Purpose of the utility model is to solve existing issues, and a kind of quick door limiting device proposed.

To achieve the goals above, the utility model adopts the technical scheme that

A kind of quick door limiting device, including mounting rack, the inner top wall of the mounting rack are equipped with encoder and motor, The encoder and electrical connection of motor, mounting rack is interior to be equipped with horizontally disposed spool, and the output shaft of the motor passes through shaft coupling Device is connected with transmission shaft, and the first sprocket wheel is fixed on the outside of the transmission shaft, is fixed on the outside of the spool and the first sprocket wheel Corresponding second sprocket wheel is connected with chain on first sprocket wheel and the second sprocket wheel, and the both ends of the spool are rotatably connected to axis It holds, the bearing is fixed on the inner sidewall of mounting rack, and reel is fixed on the outside of spool, is fixed with door on the outside of the reel Curtain, the two sides of the door curtain slidably connect sliding rail, are equipped with upper limit switch and lower position switch in the sliding rail.

Preferably, the spool is located at the lower section of motor.

Preferably, the encoder is absolute value encoder, the model ASS-1024GC-24-100-00E of encoder.

Preferably, anticollision gate seat is installed below the door curtain.

Preferably, the upper limit switch and lower position switch are located at the same side, motor and upper limit switch and lower limit Switch is electrically connected.

The beneficial effects of the utility model are: controlling motor work by encoder, the essence of door body open and close is realized Level is set, and upper limit switch and lower position switch can limit door curtain without limitation upstream or downstream, prevents rolling door from damaging.This is practical new Type structure is simple, good limit effect, improves the safety of rapid door work.

Detailed description of the invention

Fig. 1 be the utility model proposes a kind of quick door limiting device structural schematic diagram.

In figure: 1 mounting rack, 2 reels, 3 spools, 4 encoders, 5 motors, 6 first sprocket wheels, 7 transmission shafts, 8 chains, 9 second Sprocket wheel, 10 sliding rails, 11 door curtains, 12 upper limit switches, 13 lower position switch, 14 bearings.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.

Referring to Fig.1, a kind of quick door limiting device, including mounting rack 1, the inner top wall of mounting rack 1 are equipped with encoder 4 With motor 5, encoder 4 and motor 5 are electrically connected, and horizontally disposed spool 3 is equipped in mounting rack 1, and the output shaft of motor 5 passes through Shaft coupling is connected with transmission shaft 7, and the outside of transmission shaft 7 is fixed with the first sprocket wheel 6, and the outside of spool 3 is fixed with and the first sprocket wheel 6 It is connected with chain 8 on corresponding second sprocket wheel 9, the first sprocket wheel 6 and the second sprocket wheel 9, the both ends of spool 3 are rotatably connected to bearing 14, bearing 14 is fixed on the inner sidewall of mounting rack 1, and the outside of spool 3 is fixed with reel 2, and the outside of reel 2 is fixed with door curtain 11, the two sides of door curtain 11 slidably connect sliding rail 10, are equipped with upper limit switch 12 and lower position switch 13 in sliding rail 10；Spool 3 Positioned at the lower section of motor 5；Encoder 4 is absolute value encoder, the model ASS-1024GC-24-100-00E of encoder 4；Door Anticollision gate seat is installed below curtain 11；Upper limit switch 12 and lower position switch 13 are located at the same side, motor 5 and upper limit switch 12 and lower position switch be electrically connected.

In the present embodiment, the every circle of running track of motor 5 is equally divided into N number of equal portions by encoder 4, former by PID automatic control Revolving speed, torsion, position, the origin that reason differential adjusting controls motor with integral adjustment, which are remembered, realizes the accurate of door body open and close Position, the top for the lower position switch 13 that upper limit switch 12 is located at, upper limit switch 12 and lower position switch can prevent door The unconfined upstream or downstream of curtain 11.
