Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a rope head reverse pulling device. Background Art

[0002] Small elevators installed in villa buildings are called villa elevators. When installing elevators, the fixing and installation of rope heads play a vital role in the elevator system, which directly affects the safety and operation stability of the elevator. Taking the villa elevator traction ratio of 2:1 as an example, there are generally 4 traction steel ropes. One side of the steel rope passes through the car guide wheel and is wound to the top and fixed to the rope head plate by 4 sets of rope heads. The other side of the steel rope is similarly passed through the counterweight. The rope head plate is generally fixed on the guide rail, the spring part is on the upper side of the rope head plate, and the lower part fixes the steel rope.

[0003] Chinese patent CN214879384U discloses an inverted main engine villa elevator structure, comprising a main beam, a traction main engine, a car frame, a counterweight frame, a traction rope and a guide wheel. The main beam is fixedly arranged in a horizontal direction and close to the top of the elevator shaft. The traction main engine and the guide wheel are fixed on the main beam. The traction main engine is installed inverted below the main beam with the fixed surface facing upward. A car frame and a counterweight frame are arranged below the main beam. A car is fixedly arranged on the car frame, and a counterweight is fixedly arranged on the counterweight frame. One end of the traction rope is fixed to the main beam through a rope head frame and is arranged around the guide wheel. A rope pulley is arranged on the upper part of the car frame. The rope pulley passes through the traction rope as a movable pulley and moves with the car. The guide wheel serves as a fixed pulley, and the traction rope on the other side thereof is connected to the counterweight frame.

[0004] However, the roof of the elevator shaft in a general villa is basically sloping, so it is inevitable that the front is higher and the back is lower, or the left is higher and the right is lower. When the left is higher and the right is lower, when fixing the rope head of the villa elevator structure, it may be found that the car travel is not enough after the rope head is fixed.

[0005] Based on this, the utility model designs a rope head reverse pulling device to solve the above problems. Utility Model Content
