Technical field
The present invention relates to construction elevator technical field, especially relate to the security protection system of a kind of construction elevator.
Background technology
The kind of construction elevator is a lot, with or without counterweight and has counterweight two kinds by playing the method for operation.In the market
The most of construction elevator used is counterweightless formula, and drive system is placed in above cage top, existing job site
The construction elevator used mainly is made up of driving means, control device and car etc..
There is the biggest potential safety hazard in existing construction elevator, when construction elevator rests in a certain floor, workman
When the protective door of the discharging platform opening this floor carries out loading and unloading material, construction elevator is a powering up, when there being people
Member is not intended to touch the control device of construction elevator or operational error causes construction elevator to start, and easily causes people
Member's injures and deaths.Meanwhile, when the protective door of the discharging platform of other floors is in opening, construction easily occurs
Elevator cage body extension during personnel's health is outwards visited and is run touches security incident injured, that fall.And it is a certain
When the protective door of the discharging platform of floor is opened, it is difficult to discover and finds the protective door being opened in time.
Summary of the invention
Instant invention overcomes shortcoming of the prior art, it is provided that one makes construction elevator open shape at protective door
Close under state and run circuit, the security protection system of the higher construction elevator of safety.
In order to solve above-mentioned technical problem, the present invention is achieved by the following technical solutions: a kind of construction electricity
The security protection system of ladder, the protective door including the doorframe being arranged on scaffold, being hingedly connected in doorframe,
Limit switch and for controlling the control device of construction elevator, described limit switch is arranged on described doorframe
One sidewall, its contact passes doorframe frame wall, and when described protective door is closed, Qi Men limit presses described limit switch
Contact；Described limit switch connects described control device, when the contact of described limit switch does not presses, described
Control device and be in off state.
Preferably, described limit switch connects display lamp.
Preferably, described display lamp is two, and one is normally opened, and another is normally closed, by described anti-
Protect a contact of the opening and closing described limit switch of pressing and realize the switching of LED status.
Preferably, described doorframe is provided with the adjusting means for protecting described limit switch.
Preferably, described adjusting means include accommodating described limit switch, one end be connected in described door
The body of frame sidewall, is arranged at the body other end, stretches in body for regulating described limit switch position
The right angle adjustment sheet put.
Preferably, described right angle adjustment sheet is connected with described body by bolt, adjusts right angle by bolt
The position of adjustment sheet, makes the suitable distance of holding of the contact of limit switch and the door limit of safety door.
Preferably, described body is square steel.
Preferably, the both sides of described doorframe are respectively fixedly connected with at least two steel pipes, and described steel pipe fastener connects
On scaffold.
Preferably, described doorframe is two independent frame walls, relatively rotates respectively and is connected to described protective door
Both sides.
Compared with prior art, present invention have the advantage that
(1) present invention arranges limit switch by the sidewall at doorframe, and its contact passes doorframe frame wall, limit
The control device of bit switch connection construction elevator, the contact of Qi Men limit pressing limit switch when protective door is closed；
When the contact of limit switch does not presses (when protective door is opened), the control device of construction elevator is in open circuit shape
State.Only when whole protective doors are closed, the control device of construction elevator is just in channel status.Effectively keep away
Exempt from other staff and be not intended to touch the control device of construction elevator or operational error causes construction elevator to start to make
The situation becoming casualties occurs.And avoid when the protective door of the discharging platform of other floors is in unlatching shape
During state, occur that workmen's health is outwards visited and elevator cage body in being run is hung and touched feelings injured, that fall
Shape occurs.
(2) present invention is by connecting display lamp on limit switch, can be by display lamp rapid identification construction electricity
The dock floor of ladder.And the protective door working as a certain or several floors is opened or floor limit switch is out of order
Time, the floor of power-off of being out of order can be quickly found out by display lamp, corresponding problem is solved.
(3) present invention is by being provided for adjusting the adjusting means of limit-switch positions, and it is by opening spacing
Close and be placed in the body of adjusting apparatus, limit switch can be effectively protected and be not caught in the rain Exposure to Sunlight, extend it and make
Use the life-span.The most also ensure limit switch will not by falling object and workers carry's material time smash or break.
By adjusting the right angle adjustment sheet of adjusting means, it is ensured that limit switch is in suitable position in body,
Guarantee that the door limit of protective door when protective door is closed just is pressed into the contact of limit switch.Owing to limit switch is
Be placed in body is mobilizable, only need to unclamp adjustment sheet, can be taken out conveniently limit switch, spacing
Being very convenient to of switch is quick.
(4) present invention by being respectively fixedly connected with steel pipe in the both sides of doorframe, and uses fastener to connect at foot hands
On frame, the tubing of the scaffold used due to construction site and the model of fastener are substantially coincident, can
Take at the construction field (site), it is not necessary to be fabricated separately, can effectively save cost, and dismounting is flexible quickly.
(5) doorframe of the present invention uses two independent frame walls, relatively rotates respectively and is connected to described protective door
Both sides.Save material, lighter in weight, transport very convenient.
