Description

Technical Field

[0001] The utility model relates to an improved load-bearing beam structure of an elevator, in particular to a load-bearing beam structure with an integrated rope head plate. Background Art

[0002] The load-bearing beam of the elevator is the equipment foundation structure supported at the top of the elevator shaft. It is usually used in the structural form of machine roomless elevators. The traction main unit is installed on the load-bearing beam, and the counterweight and car are connected by traction ropes to drive the operation of the elevator. The traction rope will go down from the traction wheel of the traction main unit, and pass through the counterweight wheel and car wheel at both ends, then go up to the height respectively, and be fixed by the rope head plate. One end of the conventional rope head plate can be fixed on the load-bearing beam, and the other end needs to be fixed with the counterweight beam, resulting in many structures that need to be installed, and the wall foundation needs to be modified. The installation process is complicated, so it needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a load-bearing beam structure with an integrated rope head plate.

[0004] The technical solution adopted by the utility model to solve the above problems is: the load-bearing beam structure includes a main straight beam, a main engine base, a car rope head plate, and a counterweight rope head plate. The main straight beam is horizontally arranged and fixed in the wall of the shaft. The main engine base is horizontally fixed on the main straight beam. The traction main engine is fixedly installed on the main engine base. A return rope pulley is arranged at the lower part of the main engine base. A counterweight rope head plate is also arranged on the side of the main engine base. The rope head on the counterweight side is fixed on the counterweight rope head plate. The car rope head plate is fixed on the other side of the car centerline of the main straight beam. The car side rope head is fixed on the car rope head plate. The traction rope on the counterweight side passes through the first counterweight rope pulley downwards and then passes through the return rope pulley upwards, then passes through the second counterweight rope pulley downwards and then connects to the counterweight rope head plate upwards. The traction rope on the car side passes through the car rope pulley downwards and then connects to the car rope head plate upwards. Both the car rope head plate and the counterweight rope head plate can be installed on the main straight beam, and by returning the rope, the counterweight requirements are reduced, the volume is reduced, and the span of the traction rope is reduced. The rope head can be installed close to the main straight beam, saving space.

[0005] Furthermore, the car rope head plate is fixed on the main straight beam through a cross bracket, the cross bracket forms a horizontal support surface, and fixes the car rope head plate. The cross bracket and the main straight beam form a support surface, and the car rope head plate can be installed horizontally, and the fixation is more reliable.

[0006] Furthermore, the car rope end plate and the counterweight rope end plate both have holes corresponding to the number of traction ropes, and the ends of the traction ropes are fixed through the holes and through the fixings. The rope ends of the traction ropes are fixed separately, which is not easy to fall off, and a margin is left for safe work.

[0007] Furthermore, a speed limiter pad is fixed on the main straight beam, a car speed limiter is installed on the speed limiter pad, and the speed limiter pad is arranged near the car rope head plate. The speed limiter pad can also be integrated on the main straight beam to simplify the structure.

[0008] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the elevator load-bearing beam structure, in which the fixing structure of the rope heads is integrated into the main structure of the load-bearing beam, thus saving space and reducing the amount of civil construction, which is conducive to optimizing the construction period and improving installation efficiency.
