Description
Technical Field
The utility model relates to an elevator safety device, especially a locking rope fastening device that prevents overloading.
Background
The elevator is increasingly widely applied to modern society as a vertical transportation vehicle, and the elevator safety technology is an important subject. The detection device for the overload of the elevator mainly has two modes in the industry, one mode is to use a car bottom as a movable car bottom, when the load in the car is overweight, the car bottom has partial micro-motion deformation, and the overweight is detected by detecting the micro-motion deformation of the car bottom; and the other method is characterized in that after the elevator car is overloaded, the traction steel wire rope is excessively pulled tightly, so that the rope head combination of the steel wire rope deforms, and the overload is controlled by detecting the deformation of the rope head combination. However, the conventional overload control device has a complex structure and is complex to install, and the manufacturing cost is high. Therefore, the prior art has the problems of complicated structure, troublesome installation and high manufacturing cost.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a locking rope fastening device that prevents overloading. The utility model has the characteristics of simple structure, simple to operate and low in manufacturing cost.
The technical scheme of the utility model: a looseness-proof overload-proof rope head device comprises a car rope head plate, a rope head rod is arranged on the car rope head plate, a super-carrier plate is arranged at the upper end of the rope head rod, and a limit switch is arranged above the super-carrier plate; a guide rod is arranged at the end part of the upper surface of the rope hitch plate of the lift car, a linear bearing is arranged on the guide rod, and the linear bearing is fixed on the lower surface of the super-carrier plate; the elevator car rope hitch further comprises an overload switch arranged on one side above the car rope hitch plate, and a magnet fixed on the lower surface of the overload plate is arranged above the overload switch.
In the anti-loosening and anti-overloading rope head device, the upper end of the guide rod is provided with a switch bracket positioned above the overloading plate; the limit switch is fixed below the switch bracket.
In the above-mentioned anti-loose and anti-overload rope head device, the rope head rod penetrates through the car rope hitch plate, and the spring of the rope head rod is located between the car rope hitch plate and the overload plate.
Compared with the prior art, the rope end rod is fixedly penetrated on the rope end plate of the lift car, the overload plate is arranged above the rope end rod, the overload switch is arranged on one side above the rope end plate of the lift car, and the corresponding magnet is arranged on the lower surface of the overload plate, so that overload monitoring is completed; the monitoring of the loosening state of the steel wire rope is completed by arranging the limit switch above the overload plate; through the mutual cooperation between the above-mentioned structure, accomplish overload and locking pine and take off and detect, simple structure not only, simple to operate is convenient for daily maintenance, and manufacturing cost is also lower moreover. To sum up, the utility model has the characteristics of simple structure, simple to operate and low in manufacturing cost.

The labels in the figures are: 1-a lift car rope hitch plate, 2-a rope hitch rod, 3-a super-carrier plate, 4-a limit switch, 5-a guide rod, 6-a linear bearing, 7-an overload switch, 8-a magnet and 9-a switch bracket.
Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A locking and overload preventing rope head device is shown in figures 1-2 and comprises a car rope head plate 1, a rope head rod 2 is arranged on the car rope head plate 1, a overload plate 3 is arranged at the upper end of the rope head rod 2, and a limit switch 4 is arranged above the overload plate 3; a guide rod 5 is arranged at the end part of the upper surface of the cage rope hitch plate 1, a linear bearing 6 is arranged on the guide rod 5, and the linear bearing 6 is fixed on the lower surface of the super-carrier plate 3; the elevator car rope hitch plate further comprises an overload switch 7 arranged on one side above the car rope hitch plate 1, and a magnet 8 fixed on the lower surface of the overload plate 3 is arranged above the overload switch 7.
The upper end of the guide rod 5 is provided with a switch bracket 9 positioned above the overload plate 3; the limit switch 4 is fixed below the switch bracket 9.
The rope head rod 2 penetrates through the car rope head plate 1, and a spring of the rope head rod 2 is positioned between the car rope head plate 1 and the overload plate 3.
The quantity of guide arm is 4, is located 4 end angles of car rope hitch plate respectively.
Rope end stick is installed on car rope hitch plate, and the guide arm is installed in car rope hitch plate top (and run through super support plate), and linear bearing passes the guide arm (notice very much, and linear bearing contains the ball, can freely slide on the guide arm) to overload the board and install in linear bearing's top, through the action of gravity, super support plate is kept flat in rope end stick's top, supports super support plate, makes linear bearing not down fall.
When the elevator is overloaded, the spring of the rope head rod is compressed, the overload plate is downward along with the end head of the rope head rod, the magnet is close to the overload switch 7, and the trigger switch gives an alarm.
When the steel wire rope is loosened, the spring of the rope head rod rebounds, and the end head of the rope head rod pushes the overload plate upwards, so that the overload plate triggers the limit switch to act.
