The utility model content
The purpose of this utility model provides a kind of safety inspection door, can solve access door on the equipment such as present rotary screen realized opening by electric pushrod or hydraulic cylinder closed, the high problem that is prone to fault of cost.
The purpose of this utility model is achieved through the following technical solutions:
The utility model embodiment provides a kind of safety inspection door for rotary screen, comprising:
Doorframe, door-plate and manual driving device; Wherein,
Described door-plate is arranged on the doorframe;
Described manual driving device is arranged on the described doorframe;
Described door-plate is connected with described manual driving device, and described manual driving device can drive the described door-plate of control and open or close at described doorframe.
Can be found out by the above-mentioned technical scheme that provides, the access door that the utility model embodiment provides drives by manual driving device, does not need electric power, and not fragile, safe and reliable, cost is low, and Non-energy-consumption is easy to use.
Description of drawings
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, the accompanying drawing of required use was done to introduce simply during the below will describe embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain other accompanying drawings according to these accompanying drawings.
The schematic diagram of the safety inspection door that Fig. 1 provides for the utility model embodiment;
The application schematic diagram of the safety inspection door that Fig. 2 provides for the utility model embodiment.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on embodiment of the present utility model, those of ordinary skills belong to protection domain of the present utility model not making the every other embodiment that obtains under the creative work prerequisite.
Below in conjunction with accompanying drawing the utility model embodiment is described in further detail.
The utility model embodiment provides a kind of safety inspection door, can be used for rotary screen etc. and need to enter on the equipment of maintenance, and as shown in Figure 1, 2, this safety inspection door comprises: doorframe 1, door-plate 2 and manual driving device 3;
Wherein, door-plate 2 is arranged on the doorframe 1;
Door-plate 2 is connected with manual driving device 3, and manually the moving drive unit driving of operator control door-plate 2 opens or closes at doorframe 1.
In the above-mentioned safety inspection door, manual driving device 3 is by wire rope 33, pulley 31, consist of with capstan winch 32 and the handle 34 of gear pair; Wherein, pulley 31 and be fixedly installed on the doorframe 1 with the capstan winch 32 of gear pair, both keep certain intervals;
Above-mentioned safety inspection door can also arrange approach switch 4, is arranged on the doorframe 1, and is corresponding with door-plate 2 edges, triggers approach switch 4 when door-plate 2 is opened;
Approach switch is electrically connected with the drive unit of rotary screen, triggers approach switch after described door-plate is opened, and can disconnect the power supply of the drive unit of rotary screen, guarantees to enter into the safety of maintainer in the rotary screen.
In the above-mentioned safety inspection door, the door-plate bottom is connected with doorframe by movable rotation-shaft, close or set level formula and open so that door-plate can erect formula on doorframe, wire rope one end of manual driving device is fixed on the upper-end part of driving of door-plate, gravity by door-plate self then can put down door-plate from doorframe and open the safety inspection door like this, or the wire rope pull-up door-plate by manual driving device, the closed safe access door.
As shown in Figure 2, this access door is by rope traction, is connected with capstan winch with gear pair by pulley, and the operating grip that rotates capstan winch can be realized the folding of access door not needing any electric power or hydraulic system, so unregulated power consumption.One jiao at access door is equipped with approach switch, and equipment can not start by electrical control system index drum sieve when the door opening.Because rotary screen is the afterbody discharging, the space of discharging between the screen drum of rotary screen shell and needs maintenance or cleaning, personnel can't directly enter, so door-plate (door-plate can adopt the checkered steel plate manufacturing) is opened downwards, door-plate puts down fully just becomes the pedal that enters screen drum when being the level of state, just can enter screen drum inside by this pedal staff and overhaul.Equipment can't start support personnel's safety when maintenance or cleaning equipment.
Access door of the present utility model has following features:
Become the pedal of maintainer's turnover when (1) the door body puts down.
(2) opening and closing of access door do not need any power, and energy free consumption is not safeguarded.
(3) operation is simple and reliable for access door, and fault rate is almost nil.
(4) be with electric defencive function, guarantee maintainer's safety.
(5) access door structure optimization, low cost of manufacture.
The access door that the utility model embodiment provides is simple for structure, and is safe and reliable, non-power consumption.Its application is not limited to the environmental protection equipments such as rotary screen, all can use this access door for other plant equipment that need personnel's access arrangement inside to overhaul or clear up.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the variation that can expect easily or replacement all should be encompassed within the protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claims.
