Abstract
The utility model discloses an emergency stop device for a conveyer. The conveyer conveying people and oversize materials can automatically stop under the emergency condition so as to protect people and equipment. The utility model is composed of a limit switch, and at least one group of tabbing mechanisms. The utility model is characterized in that each tabbing mechanism comprises a belt and a support frame, wherein the belt is horizontally positioned above a conveyor belt of the conveyor with certain height, and the support frame tilts towards the running direction of the conveyor belt after the support frame collides with the belt. The front end of the support frame is provided with collision iron. The limit switch is used for stopping the conveyer under the emergency condition; a switch knob is arranged below the collision iron. The utility model has the advantages of simple structure, and flexible action.
Description
The utility model belongs to a kind of conveyer emergency shut down device, and one makes conveyer crash arrest safety apparatus by the bump of superelevation object on the belt conveyor self specifically, particularly to personnel's rescue.
The belt feeder original design has accident backguy emergency stop device; and in case of emergency; by running person's emergency episode backguy of leaving behind; stop the belt operation; play a protective role; but coal handling system is in long-term work; because maloperation and unforeseen circumstances once took place unusually to work on belt, belt starts; and bulk materials injures contingencies such as belt by a crashing object; because can't the backguy of pulling accident on the belt that is in operation of people; add belt and move ahead 2.5 meters each second, personnel can't save oneself on belt at all, so the as easy as rolling off a log human casualty accident that causes; make the person and equipment all be subjected to great harm, had a strong impact on production.
The utility model purpose is to disclose a kind of conveyer emergency stop mechanism, and this device can make on the belt that the people is in operation, and also can make super large material on the operating belt with the conveyer auto-stop, thereby reaches the purpose of the protection person and equipment.
The utility model is made up of at least one group of hurdle mechanism and limit switch 20 that is installed on conveyer section operation end, it is characterized in that: the described mechanism that hurdles can be skewed bracing frame 3 to the belt conveyor service direction after comprising a belt 15 that is horizontally placed on conveyer belt top certain altitude and superelevation thing bump, the bottom of bracing frame 3 and the permanent seat 22 that is fixed on the conveyer central support 2, hinged by axle 8, the vertical riser of permanent seat has the hole, be installed with a bolt 5 that is anchored on the bracing frame 3, vertical riser one side is with compression spring 7 on bolt 5, bracing frame 3 has one to hit iron 16 to what protract apart from hinge-point a distance, termination, described limit switch is a switch that can make the action of conveyer emergency parking mechanism, be fixed on the central support 2, its release knob is in the below of hitting iron 16.
The more perfect scheme of the utility model is that its composition also comprises a safety guide rail 13.Safety guide rail also is that a not bevelled that is horizontally placed on the load-transfer device top is hurdled, and is made up of two supports and belt.Be fixed on the central support of hurdling between mechanism and the load-transfer device head cylinder.
Below with reference to the embodiment figure that bows the technical scheme details is described.
Fig. 1 is the utility model embodiment installing condition front view.
Fig. 2 is the utility model embodiment installing condition lateral plan.
Fig. 3 is the I partial enlarged drawing of Fig. 1.
Fig. 4 is that the B of Fig. 3 is to view.
Fig. 5 is the II partial enlarged drawing of Fig. 2.
As shown in Figure 1, the A direction is the belt conveyor service direction, bracing frame 3 is symmetric arrangement on central support 2, belt 15 height of mechanism of hurdling passes through smoothly with normal transmission material, fall into improper object on the belt conveyor and make, hit to bump as people or super large thing and be as the criterion, 1 is carrying roller among the figure, and 13 is safety guide rail.
Fig. 5 belt 15 is by nut 17, and bolt 18, parallels 19 are fixed on the bracing frame (3).
This device is installed on the head of belt feeder, apart from head centre of the drum apart from being 5 meters (2.5 meters second * floor times of belt feeder belt speed 2 seconds=apart from 5 meters on head).When belt feeder normally moves; this device is because compression spring 7 effect is stood on the belt frame, and limit switch is action not, as people or bulk materials during by this device; meet on the protection belt of this device; because effect of inertia, belt moves ahead, and bracing frame leans forward; hit iron and run into limit switch; limit switch links to each other with the belt feeder chain apparatus, makes belt feeder out of service, thereby avoids personal injury and device damage.Because the protection belt that adopts is a soft material, the people bumps against that the belt top is unlikely to come to harm.In order to prevent contingency, this device has also been established dual position limitation protection and the protection of dual frame, makes it safety factor and is greatly improved.
Existing homemade belt feeder only is provided with the backguy of emergency engine kill accident; how not consider under special circumstances on machine emergency engine kill; by putting into operation of this device; just can remedy intrinsic deficiency; when making people or bulk materials by device, belt feeder is out of service, and Daqing oil field thermoelectric power station fuel subsidiary factory has hauled oneself willingly into since this device; bulk materials auto-stop 5 times every year on average, the annual personnel are rescued 0.5 person-time on belt.This shows that this device has really played the effect of the protection person and equipment, be the safety of power plant, economical operation has played irreplaceable effect.
This device has features simple structure, flexible movements, and the plurality of advantages such as maintenance cost is low is The indispensable part of coal handling system safety and economic operation.
Claims (2)
1 one kinds of conveyer emergency stop mechanisms, form by at least one group of hurdle mechanism and limit switch (20) that is installed on conveyer section operation end, it is characterized in that: the described mechanism that hurdles comprises that one is horizontally placed on the belt (15) of conveyer belt top certain altitude and can be skewed bracing frame (3) to the belt conveyor service direction, the bottom of bracing frame (3) and the permanent seat (22) that is fixed on the conveyer central support (2), hinged by axle (8), the vertical riser of permanent seat has the hole, be installed with a bolt (5) that is anchored on the bracing frame (3), go up vertical riser one side at bolt (5) and be with compression spring (7), bracing frame (3) has one to hit iron (16) to what protract apart from hinge-point a distance, termination, described limit switch is a switch that can make the action of conveyer emergency parking mechanism, be fixed on the central support (2), its release knob is in the below of hitting iron (16).
2. conveyer emergency stop mechanism as claimed in claim 1 is characterized in that its composition also comprises a safety guide rail (13).Safety guide rail also is that a not bevelled that is horizontally placed on the load-transfer device top is hurdled, and is made up of two supports and belt.Be fixed on the central support between the cylinder of hurdle mechanism and load-transfer device head.
