Description

Electric interlocking safety warning system for floor protection door of construction elevator

technical field

The utility model belongs to the technical field of elevator floor protective doors for building construction.

Background technique

The existing construction elevator floor protection door and electrical interlocking device are easily damaged. Since there is no fault display and alarm device, it is difficult to find the fault point after the damage. It takes a lot of time to find the fault, and the fault floor cannot be found in time. security risks. In order not to delay working hours, construction workers usually do not consciously close the floor protective door, and the electrical interlocking device is artificially placed in a normally open state, causing the floor protective door and electrical interlocking device to often be in an invalid state, which cannot provide actual and effective protection. effect.

Contents of the invention

The purpose of this utility model is to solve the problems existing in the prior art, and to provide a construction with an electrical interlock device that can immediately display an alarm when the floor protective door fails, so as to eliminate the fault in the shortest time and improve safety. Elevator floor protection door.

The purpose of this utility model is achieved through the following technical solutions:

The electrical interlocking safety warning system for the protective door of the construction elevator, including the outward-opening floor protective door of the opposite construction elevator installed on each floor, the set-type latch installed outside the protective door of each floor, respectively connected to the movable rod of the set-type latch The travel switch at the tail, the electrical interlock distribution box electrically connected with each travel switch, and the display lamp installed on the electrical interlock distribution box and electrically connected with the travel switches of each floor.

The utility model adopts the outward-opening floor protective door, so that the movable rod of the set-type latch is adapted to the installation position of the travel switch. When the movable rod of the latch moves to withdraw from the latch sleeve, the display lamp connected with the travel switch immediately displays an alarm. It can be clearly seen that the display light of the protective door on that floor is alarming, and it can be found in real time that the latch has been disengaged and the floor protective door is not tightly closed, and remedial measures can be taken in time to eliminate potential safety hazards.

The utility model has the advantages of simple structure, timely and accurate alarm, and can ensure the safety of construction and production.

Detailed ways

Further set forth the content of the present utility model below in conjunction with accompanying drawing of description.

As shown in Figure 1, the electric interlocking safety warning system of the construction elevator floor protection door described in the utility model includes the outward opening of the opposite construction elevator installed on each floor (the 2nd floor and the 3rd floor shown in this embodiment). Type floor protection door 1, set-type latches installed outside the protective doors on each floor 2, travel switches respectively connected to the tail of the set-type latch movable rod 3, electrical interlock distribution box electrically connected to each travel switch 4, installation The indicator lights 4a on the electrical interlock distribution box and electrically connected to the travel switches of each floor, the electrical interlock distribution box is installed on the first floor.

The utility model reasonably matches the installation position of the set-type latch 2 installed outside the outward-opening floor protective door 1 and the travel switch 3, and installs an electric interlock distribution box 4 to cooperate with it, so that the faulty floor indicator light 4a available for immediate display.

The electrical interlock distribution box provided by the utility model is mainly used to realize the electrical interlock and fault indication of the floor protective door and the construction elevator, and can change the voltage of 380V to 36V, greatly reducing the hidden danger of electric shock, and the floor fault indicator light can be used in the shortest time. Find the faulty floor inside for immediate troubleshooting.

As shown in Figure 2, Figure 3, Figure 4, and Figure 5, the working principle of the electrical interlock distribution box is as follows: the electrical interlock system is introduced into the electrical interlock distribution box from the original power supply control circuit shown in Figure 2, through The transformer makes the line on each floor be 36V voltage, and then connects back to the electrical interlock distribution box through the intermediate relay and the travel switch (normally open circuit) of each floor to control the floor interlock. The floor indicators are connected to the travel switches (normally closed loops) of each floor through the terminals of the electrical interlock distribution box, and then returned to the electrical interlock distribution box to connect to the floor indicators, so that the entire system can be interlocked.

The utility model has the advantages of simple structure, easy installation and safe and reliable use.
