Abstract

The utility model relates to a safe protection device used at a piece of hoisting machinery and essentially solves the technical problem of an artificial misoperation existent during a maintenance, inspection and repair for a piece of hoisting equipment. The technic proposal of utility model detailed as follows: A safe startup device by electric interlock for a piece of hoisting machinery is provided and characterized in comprising a power control box which comprises two electric locking normally close contacts which are equipped at a main circuit of the hoisting equipment by a serial and a change-over indication system. Two serial electric locking normally close contacts are connected with a green indicator and, a red indicator is parallel connected with two ends of an electric locking serial branch. A startup button, a stop button and a startup contactor coil have a serial connection and then as a whole a parallel connection with two ends of a green indicator. A normally open switch at the startup contactor has a parallel connection with the startup button at two ends of the startup button. The utility model is mainly used for preventing an involuntary operation made by an operator during an inspection and repair for the hoisting machinery.

Description

A kind of elevator machinery electrical interlocks safety is started device
Technical field:
This practical a kind of safety guard that is applied to elevator machinery that relates to.Can reach the maloperation of avoiding the elevator machinery navigating mate and personal injury accident and the equipment breakdown that causes.Satisfy the electrical design requirement of hoisting crane, realize that electrical interlocks starts the electric control loop that board is effectively controlled hoisting crane, reach the purpose of chain control protection, the equipment and the person are carried out the actv. safety guard-safeguard.
Background technology:
The berthing facilities system mainly relies on hoisting and handling equipments such as handling bridge, door machine, driving to carry out production operation, and in the maintenance and maintenance of weight-lifting equipment, the board system will take place because the safety misadventure that human factor causes if the not strict execution of discovery is started.The weight-lifting equipment regulation must be started the board system by actuating equipment at present, the existing board implementation status of starting is to be provided with two at the weight-lifting equipment operator's compartment to start board, take off wherein one during the service personnel maintenance, navigating mate starts the complete situation lower moveable car of board at two to be operated.This method of operation can effectively be avoided in actual applications owing to coordinating the bad accident that causes between operating personal and the service personnel, if but also exist service personnel and navigating mate accountability can not occur the possibility of maloperation by force.
Summary of the invention:
The purpose of this utility model provides a kind of elevator machinery electrical interlocks safety and starts device, mainly solves to start people that the board system the exists technical matters for maloperation in the maintenance of weight-lifting equipment and maintenance.
The technical solution of the utility model: a kind of elevator machinery electrical interlocks safety is started device, comprise power controling box, control box includes 2 electric lock normally closed contacts and switches indicating system, 2 electric lock normally closed contacts are connected in the major loop of weight-lifting equipment, 2 polyphone electric lock normally closed contacts are contacted with green indicating lamp again, red indicating light is connected in parallel on electric lock polyphone branch road two ends, be parallel with tandem promoter button, stop button and starting contactor coil successively at the green indicating lamp two ends, be parallel with the starting contactor normal open switch at the start button two ends.
When 2 electric lock normally closed contacts were closed, major loop can't get electric, and main power source can't be worked; Practical operation: during ordinary production, the elevator machinery chaufeur inserts 2 electric lock normally closed contacts with private key, and two electric locks are all opened, and main circuit power is all connected, at this moment can normal operation.Run into maintenance maintenance or multiplex (MUX) and plant when carrying out coordinative operation, each maintenance work post (being generally two work posts) is respectively closed an electric lock, takes a key away, and at this moment, weight-lifting equipment can't start, and plays the safety guard-safeguard effect.When normal running, lost efficacy as emergency stop switch, any electric lock can substitute emergency stop switch.Carry out the chain maloperation that more can avoid navigating mate if equipment is started the main power source of board and loading-unload machine, guarantee that device security uses.
The beneficial effects of the utility model are, start device by electrical interlocks and transfer objective control to thing to by the behavior control to the people, reach the purpose of chain control protection, and the equipment and the person are carried out the actv. safety guard-safeguard.
Description of drawings:
Accompanying drawing is the utility model schematic circuit diagram.
Among the figure: 1-1# electric lock normally closed contact, 2-2# electric lock normally closed contact, 3-red indicating light, 4-green indicating lamp, 5-stop button, 6-start button 7-starting contactor coil, 8-starting contactor normal open switch.
The specific embodiment: referring to accompanying drawing, a kind of elevator machinery electrical interlocks safety is started device, comprise power controling box, the control box setting includes 2 electric lock normally closed contacts and switches indicating system, 1# electric lock normally closed contact 1 and 2# electric lock normally closed contact 2 are connected in the major loop of weight-lifting equipment, 2 polyphone electric lock normally closed contacts are contacted with green indicating lamp 4 again, red indicating light 3 is connected in parallel on electric lock polyphone branch road two ends, be parallel with tandem promoter button 6 successively at the green indicating lamp two ends, stop button 5 and starting contactor coil 7 are parallel with starting contactor normal open switch 8 at the start button two ends.
1# electric lock normally closed contact 1 and 2# electric lock normally closed contact 2, stop button 5, start button 6 are being controlled the connecting and disconnecting of main circuit power starting contactor jointly.The effect of this circuit is mainly in two kinds of situation:
First kind: when main circuit power does not start (not adhesive of starting contactor normal open switch 8), when having only an electric lock normally closed contact (1 or 2) to open, red indicating light 3 is bright, if at this moment press start button 6, major loop must not, the 8 not adhesives of starting contactor normal open switch, main circuit power is disconnected.Have only two electric lock normally closed contacts (1 and 2) when opening simultaneously, green indicating lamp 4 is bright, if at this moment press start button 6, major loop gets electric, 8 adhesives of starting contactor normal open switch, and weight-lifting equipment can start.
Second kind: when main circuit power has started (8 adhesives of starting contactor normal open switch), when any one electric lock normally closed contact (1 or 2) is opened, the major loop dead electricity, starting contactor normal open switch 8 disconnects, red indicating light 3 is bright, main circuit power disconnects, and hoisting crane quits work, and plays the effect of emergency stop switch.
The model of electric lock is LAY16 (LB), and market is on sale, can choose the electric lock model according to voltage, the current value of control loop.
