Description
Technical field
The utility model relates to a kind of door of controlling turnover building hoist hoistway layer mouth, is a kind of layer of controlling device for doors specifically.
Background technology
Building hoist is the vertical transport equipment that the camp site is most widely used.Elevator has the dual-purpose and independent goods of people's goods with two kinds, and wherein material hoist is used more general.Almost each monomer all disposes one at least.No matter be that goods is used or the dual-purpose elevator of people's goods, the design of its car outlet and external scaffolding porthole layer door and application feature have vital relation to the safe handling of elevator.Yet, the complete system plant of present domestic production elevator scarcely supporting layer door system, the layer door that use the camp site made by oneself by unit in charge of construction mostly, the switch doors that adopt manual push-rod lock fixed structure more, the inorganic Electricity Federation of layer door lock, elevator craning cage all can be opened layer door in any position, can not satisfy the requirement of standard.
It is that 201102850 Chinese utility model patent " a kind of layer door safety control system of building hoist " discloses a kind of building safety device that publication number is arranged, and includes Main Control Tank, car, car position detector, safety landing door, inductor, sub-control box; Be fixedly installed on the electromagnetic lock on the described safety landing door; And be arranged on threshold switch on the described layer door; Wherein, described car position detector signal output part links to each other with the contact switch of described Main Control Tank electric loop, sensor output signal links to each other with the control end of electromagnetic lock coil, and inserting the sub-control box electrical circuit, described threshold switch connects described sub-control box electric loop and Main Control Tank electric loop respectively.The utility model is by intercommunication formula mode, utilizes the electromagnetic lock structure of dynamo-electric interlock, and the sub-control box of ground-surface Main Control Tank and each floor is interconnected by electrical control, realize that layer door closed and the cage operation between safety control.But its nearly all binary pair all is by automatically controlled, with respect to the easy et out of order of mechanical control, and the input cost height, the installation unloaded operation is loaded down with trivial details, can not well satisfy the needs of present China town and country construction.
The utility model content
The technical problems to be solved in the utility model is: a kind of layer controlling device for doors of mechanical mechanism controls is provided, and it can pin layer door when car does not rest in the porthole; When lift leans against the porthole, untie a layer door lock, allow layer door manually be opened, and can allow layer door remain on opening; When car leaves porthole relief layer door SELF CL and locked.It should possess characteristics simple in structure, easy to loading and unloading, with low cost.
The purpose of this utility model can reach by following measure, and it comprises: lance, normally closed sliding pin, often open sliding pin, spring layer door, car collision block.Layer door is installed in the floor porthole by the hinge of band torsion spring; The top and the bottom of described normally closed sliding pin and Chang Kai sliding pin are equipped with the inclined-plane, and all are provided with elastic telescopic mechanism, can shorten length when stressed; Described lance can be under external force along its longitudinal travel, it is provided with reset attachment, make it after losing external force, can get back to initial position, described lance is provided with two inclined-planes, the inclined-plane of their respectively corresponding described normally closed sliding pins and Chang Kai sliding pin, what cooperate with normally closed sliding pin is referred to as normally closed inclined-plane, with often open that sliding pin cooperates be referred to as often to open the inclined-plane; One of described lance is stretched out outside the porthole, and described car collision block is fixed on the car, and when cage operation extremely flushed with the porthole, described car collision block just in time can push of described lance.
Operation logic of the present utility model is as follows: when car does not rest in the porthole, and the normally closed sliding pin of normally closed inclined-plane jack-up on the lance, the part that normally closed sliding pin ejects is blocked layer door and is stoped its unlatching, and this opens the inclined-plane often and does not withstand and often open sliding pin; When car rests in the porthole, car collision block extruding lance is subjected to displacement it, normally closed inclined-plane on the lance is the normally closed sliding pin of jack-up not, normally closed sliding pin withdrawal, the no longer unlatching of trapping layer door, this opens inclined-plane jack-up often and often opens sliding pin, often opens the part that sliding pin ejects and makes single or double acting door can be fixed on opening; When car left the porthole, lance automatically reset again, and limit is opened the normally closed sliding pin of inclined-plane jack-up, often open the inclined-plane not jack-up often open sliding pin, layer door got back to closed condition under the effect of relying on oneself, and limited and can't open by normally closed sliding pin.
The characteristics of technique scheme are: use simple mechanical mechanism to reach design goal.Locked layer door when elevator does not rest in the porthole; When lift leans against the porthole, untie a layer door lock, allow layer door manually be opened, and can allow layer door be held open state; When elevator leaves porthole relief layer door SELF CL and locked.And the technical program is simple in structure, easy to loading and unloading, with low cost.
Technique scheme also can comprise following feature: described lance ram with or described car collision block be provided with tourelles such as roller, ball, to reduce the wearing and tearing that collision brings.
Further, described sliding pin with or the impact portions on described inclined-plane be provided with tourelles such as roller, ball, to reduce the wearing and tearing that collision brings.
