Abstract
The utility model provides a pneumatic safety door for a welding production line. The pneumatic safety door comprises rodless cylinders and a door leaf, wherein the door leaf is fixedly connected with sliding blocks of the rodless cylinders, and the rodless cylinders are electrically connected with a welding production line control unit. The pneumatic safety door can be automatically controlled, so that safety protection of operators is improved.
Description
Technical field
The utility model relates to welding and assembling production lines field, is specifically related to welding and assembling production lines Pneumatic safety door.
Background technology
Along with the raising of car body welding producing line production automation degree, the requirement of the security protection control in automation region is also more and more high, and operating personnel enter automation region need to a kind of easy to operate, safe and reliable safety door.Conventional security door is generally door leaf and is arranged on doorframe by hinge, when door leaf is closed, fixes with latch, and complex operation, is difficult to realize automatic control.Therefore, now design a kind of simple and practical, visual good safety door, realize the demand of automation line security protection.
Utility model content
The purpose of this utility model is to provide a kind of safety door that can realize automatic control, thereby improves the security protection to operating personnel.
Embodiment of the present utility model provides following technical scheme for achieving the above object:
A kind of welding and assembling production lines Pneumatic safety door, comprising: Rodless cylinder, with the door leaf that the slide block of described Rodless cylinder is fixedly connected with, described Rodless cylinder and welding and assembling production lines control module are electrically connected.
Preferably, between described welding and assembling production lines control module and described Rodless cylinder, be provided with sensor and self-locking device.
Preferably, between described welding and assembling production lines control module and described Rodless cylinder, be provided with self-locking device.
Preferably, described Rodless cylinder top is provided with limit switch.
Preferably, described door leaf is high strength glass material.
Preferably, described door leaf below is provided with pressure sensitive switch.
Preferably, the below of described door leaf lower position is provided with safety air cylinder, described safety air cylinder and the electrical connection of described pressure sensitive switch.
The utility model can be started the unlatching of safety door or close according to productive temp control by welding and assembling production lines control module, improve automaticity, for operating personnel provide better protection, and adopt Rodless cylinder can also the in the situation that of air pressure deficiency, ensure that the door leaf having promoted can not fall down and injure personnel by a crashing object.
Further, whether sensor can detect has operating personnel to enter, only have like this when welding and assembling production lines control module allows pneumatic door and open, and sensor has detected that, when operating personnel enter, pneumatic door is just opened, otherwise pneumatic door is not opened, on the other hand, in the time that sensor has detected that operating personnel enter, production line control module can be closed welding operation, provides protection for entering on-the-spot operating personnel.
Further, adopt self-locking device can ensure opening of pneumatic door.
Further, limit switch can prevent pneumatic door opened the door position.
Further, door leaf is that high strength glass material is convenient to observe the scene that is welded.
Further, urgent lifting door leaf again in the situation that the pressure sensitive switch of door leaf below can being pushed down operating personnel in pneumatic door closing process.
Further, the safety air cylinder of door leaf lower position below can be in Rodless cylinder fault and pressure sensitive switch detects the in the situation that of pushing down operating personnel by push rod jacking door leaf, protection operating personnel.
Brief description of the drawings
Next in connection with accompanying drawing, specific embodiment of the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the welding and assembling production lines Pneumatic safety door of embodiment of the present utility model;
Fig. 2 is the welding and assembling production lines Pneumatic safety door open mode schematic diagram of embodiment of the present utility model.
Description of symbols in upper figure: Rodless cylinder 1, slide block 2, door leaf 3, limit switch 4, pressure sensitive switch 5, safety air cylinder 6.
Detailed description of the invention
With reference to figure 1, the door leaf 3 that welding and assembling production lines Pneumatic safety door comprises Rodless cylinder 1, is fixedly connected with the slide block 2 of Rodless cylinder 1, Rodless cylinder 1 and the electrical connection of welding and assembling production lines control module.Like this, welding and assembling production lines control module just can be according to the break-make of the source of the gas of productive temp control Rodless cylinder 1, thereby the open mode that allows door leaf 3 to be entered Fig. 2 by Rodless cylinder 1 jacking, or door leaf 3 remains on the closed condition in Fig. 1, improve automaticity, for operating personnel provide better protection, and adopt Rodless cylinder can also the in the situation that of air pressure deficiency, ensure that the door leaf having promoted can not fall down and injure personnel by a crashing object.
As preferably, between welding and assembling production lines control module and Rodless cylinder 1, be also provided with sensor and self-locking device.Whether sensor can detect has operating personnel to enter, only have like this when under the condition that welding and assembling production lines control module permission door leaf 3 is opened by jacking, and sensor has detected when operating personnel enter, the source of the gas of Rodless cylinder 1 just can be opened, and door leaf 3 is just opened by jacking, otherwise pneumatic door is not opened, on the other hand, in the time that sensor has detected that operating personnel enter, production line control module can be closed welding operation, provides protection for entering on-the-spot operating personnel.And door leaf 3 is while being opened by jacking, utilizes the self-locking devices such as relay latching circuit can ensure that door leaf 3 is by jacking, stays open state.
Certainly, operating personnel also can be by directly sending operational order jacking door leaf 3 to welding and assembling production lines control module.
And in order to prevent that door leaf 3 is by track, the ceiling etc. of too high touching top, the position of jacking, be provided with limit switch 4 on the top of Rodless cylinder 1, when door leaf 3 is exceeded upper limit and is triggered to limit switch 4 by jacking like this, the source of the gas that limit switch can emergency cut-off Rodless cylinder 1 or force the slide block 2 of Rodless cylinder 1 descending.
Door leaf 3 adopts high strength glass material, has both ensured sufficient intensity, is convenient to again observe the scene that is welded.
In pneumatic door closing process, if the pressure sensitive switch 5 of door leaf 3 belows touches operating personnel, can give and signal of welding and assembling production lines control module promptly lifting door leaf 3 again.And; more preferably; below the lower position of door leaf 3; for example melt pit of the excavation below ground in Fig. 1; a safety air cylinder that can work alone 6 is set in melt pit; safety air cylinder 6 is electrically connected like this with pressure sensitive switch 5; in the time that pressure sensitive switch 5 touches operating personnel; even if welding and assembling production lines control module or Rodless cylinder 1 break down; or both break down while causing door leaf 3 to be lifted simultaneously; safety air cylinder 6 still can stretch out push rod jacking door leaf 3, thus protection operator safety.
Although the utility model is described in conjunction with above embodiment, but the utility model is not limited to above-described embodiment, and be only subject to the restriction of claim, those of ordinary skill in the art can easily modify to it and change, but do not leave essence design of the present utility model and scope.
