Description
Technical field
The utility model relates to automatic door control field, particularly relates to a kind of automatic door and rushes spacing automatic recovery device.
Background technology
The automatic door that in industry, uses at present is rapid door mostly, and common is rolling door or slide-lifting door, and spacing inaccurate phenomenon often appears in the main higher pulse coder of price that uses of its switch control during operation.Because automatically door-hinge can not in time stop operating after spacing rushing under the drive of drive motors; Its power is conducted to limit switch by transmission mechanism again; So automatic door-hinge and limit switch serious wear in long-term the use increase the limit switch repetitive error, the worst error value of rapid door can reach ± 15mm; The worst error value of slide-lifting door can reach ± 10mm, and seal is poor when closing.In service exceed upper limit or lower limit after automatic door can't move, just can use after needing the professional manually to reset after going wrong.Therefore, the automatic door maintenance frequency is higher, has increased personnel's input cost, and is also inconvenient in the use.
The utility model content
In order to address the above problem, rolling door or the slide-lifting door that overcomes prior art exists that the limit switch repetitive error is big, the problem of maintenance difficult, and the utility model provides a kind of automatic door to rush spacing automatic recovery device to address the aforementioned drawbacks and problem.
To achieve these goals, the technical scheme of the utility model is following:
A kind of automatic door is rushed spacing automatic recovery device; Comprise door-hinge 3, drive the drive motors 1 of door-hinge rotation, the control system 2 of control drive motors work and the pulse coder 15 of record door-hinge travel information; It is characterized in that: said door-hinge is provided with the travel switch 7 that detects the door-hinge stroke, and said travel switch is connected with door-hinge 3 through transmission device.
Said transmission device comprises sprocket wheel A and the sprocket wheel B that connects through chain 6, and its middle sprocket A is fixedly connected with door-hinge, and sprocket wheel B is connected with travel switch 7.
Said travel switch 7 comprises stroke lever 12; The upper limit slide block 10 and the lower limit slide block 11 that are installed on the stroke lever and keep at a certain distance away; Wherein upper limit of the corresponding respectively installation of the outer side edges of upper limit slide block and lower limit slide block is touched switch 9 and lower limit touching switch 8; Upper limit touching switch is connected with lower limit relay 13 with upper limit relay 14 respectively with lower limit touching switch, and said sprocket wheel B is fixedly connected on an end of stroke lever 12.
Said upper limit relay all passes through wiring terminal with the lower limit relay and is connected 15 with control system 2 with pulse coder respectively.
Said pulse coder is fixedly connected with door-hinge through sprocket wheel A.
The utility model compared with prior art; Increased upper limit relay and lower limit relay, automatic door has been rushed in process of rising or falling broken off power set at once after spacing, reduced the damage of impulse force and door-hinge by travel switch control; Improved control accuracy; Reduce the automatic door maintenance frequency, improve application life, practice thrift cost of labor.Below in conjunction with accompanying drawing the utility model is done further explanation.

The specific embodiment
As shown in Figure 1; One end of door-hinge 3 is connected with drive motors 1, and the other end of door-hinge 3 is connected with travel switch 7 through transmission device, and wherein transmission device can adopt the kinds of drive such as gear drive, belt transmission; This programme adopts the mode of chain gear transmission; Be specially: at the fixing sprocket wheel A of the other end of door-hinge 3, sprocket wheel A constitutes transmission device through chain 6 with sprocket wheel B, and sprocket wheel B is fixed on the stroke lever 12 of travel switch 7.
Travel switch 7 comprises a stroke lever 12; One end of stroke lever 12 is fixedly connected with sprocket wheel B; On stroke lever, being fixed with two position limiting slide blocks that keep at a certain distance away, is respectively upper limit slide block 10 and lower limit slide block 11, in the both sides of two position limiting slide blocks a touching switch is set respectively; Be respectively that 8, two touching switches of upper limit touching switch 9 and lower limit touching switch are connected with lower limit relay 13 with upper limit relay 14 respectively.Wherein the automatic door of the distance between the touching switch of two position limiting slide blocks and one of which side and the setting position of transfiniting is relevant; In case promptly the position limiting slide block of certain side triggers the touching switch; Just show that automatic door runaways; And the stroke manner of breathing of the pulse coder that transfinites be connected with its door-hinge through sprocket wheel A of automatic door record closes, so as long as make stroke lever 12 and door-hinge 3 synchronous through transmission device, can conveniently understand the stroke state of automatic door.In this programme, after drive motors 1 drove door-hinge 3 rotations, sprocket wheel A promptly moved horizontally through the slide block that sprocket wheel B drives on the stroke lever simultaneously; When the upper limit or lower limit are rushed in door-hinge 3 rotations; Respective slide on the stroke lever 12 will be pushed corresponding touching switch, and corresponding upper limit relay 14 or lower limit relay 13 are connected, in case relay is connected; Then pass through the signal of wiring terminal break impulse encoder 15; Make it no longer write down the information after automatic door is rushed limit, the control system 2 that connects the work of control drive motors through wiring terminal simultaneously moves its control drive motors 1 in the opposite direction, and the automatic door of rushing after the limit is got back in the controlled range.After in automatic door is got back to normal range (NR), door-hinge also through the transmission of sprocket wheel A-sprocket wheel B, gets back in the normal activity scope slide block on the travel switch 12; Touching switch this moment breaks off; Corresponding relay quits work, and automatic door returns in the former setting travel range, and pulse coder 15 restarts; The opening entry travel values realizes that thus automatic door rushes the purpose that recover automatically spacing back.
The utility model is described through embodiment; But the utility model is not constituted restriction; Description with reference to the utility model; Other of the disclosed embodiments change, and expect easily that like the professional person for this area such variation should belong within the scope thereof of the utility model.
