Description

Technical Field

[0001] This utility model relates to an improvement in the load-bearing beam structure of an elevator, specifically a symmetrical universal single-beam traction machine load-bearing beam. Background Technology

[0002] The traction unit of a machine-room-less elevator needs to be installed on a load-bearing beam at the top of the elevator shaft. Since the space allowance in different buildings varies, different load-bearing beam structures need to be set according to different shaft environments. The installation process requirements of the load-bearing beams will also be different, thus prolonging the construction time and increasing the construction cost. In addition, since the dual or even multiple elevator configurations are now common in buildings, the environments of adjacent elevator shafts are often symmetrical and mirrored. Therefore, the layout of the elevator shaft is also often symmetrical. Thus, a load-bearing beam structure that can be used for symmetrical and universal installation is needed. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide a symmetrical universal single beam traction machine load-bearing beam.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A load-bearing beam is set on one side of the elevator shaft cross-section, and both ends of the load-bearing beam are fixed to the front and rear walls of the shaft. The load-bearing beam includes a beam body, on which traction machine mounting positions, speed governor mounting positions, and rope end mounting positions are provided. The beam body is a straight, rigid structure, with both ends located within the shaft wall. The traction machine mounting positions and speed governor mounting positions are located at the upper part of the beam body, and the rope end mounting positions are at the lower part of the beam body. The elevator car is located in the space on the side of the beam body in the cross-section, and the car wheel is set corresponding to the traction wheel of the traction machine. A counterweight frame is set in the space below the beam body. The load-bearing beam is a single beam structure, on which the main elevator traction structure is installed. The single beam structure can be set near the side of the shaft, effectively utilizing the remaining space in the car space. Furthermore, the counterweight frame and the car can be set opposite each other, facilitating symmetrical interchange and effectively improving construction efficiency.

[0005] Furthermore, the main beam is constructed of H-shaped steel with two planes positioned vertically. The planes include mounting positions for the traction machine, speed limiter, and rope ends. Support plates are welded to both ends of the main beam, positioned between the beam and the grooved surface of the wall. The use of self-rigid H-shaped steel for the main beam, connected to the wall foundation via the support plates, prevents deformation of the beam itself.

[0006] Furthermore, the traction machine mounting position includes a traction machine base plate and a reinforcing plate. The traction machine base plate is horizontally welded to the upper surface of the beam body, forming a horizontal fixing surface. The traction machine main unit is fixed to the traction machine base plate. The reinforcing plate is welded and fixed to the bottom of the traction machine base plate, and its cross-section is supported in the space lateral to the beam body. The reinforcing plate is welded and fixed to the beam body. Because the traction machine base plate has a large area, a reinforcing plate is needed at the bottom. The reinforcing plate supports both the bottom of the traction machine base plate and the cross-sectional space of the beam body, thus serving both a supporting and structural strengthening function.

[0007] Furthermore, stiffening ribs are provided in the lateral space of the beam body, with the cross-sectional shape of the stiffening ribs corresponding to the lateral space. The stiffening ribs are welded and fixed to the beam body. The function of the stiffening ribs is to strengthen the structure of the beam body, forming vertical support between the stiffening ribs and the beam body, and also to strengthen the position of the adjacent equipment installation.

[0008] Furthermore, the speed limiter mounting position includes a speed limiter mounting plate, which is horizontally fixed to the upper surface of the beam body. The mounting plate has mounting holes and a traction rope hole, with the traction rope hole penetrating downwards through the beam body structure. The traction rope is the connecting part for the speed limiter's downward control caliper, and the section through which it passes requires structural avoidance.

[0009] Furthermore, the rope end mounting position includes a rope end plate, which is horizontally fixed to the lower surface of the beam body. A rope end mounting hole is provided on the rope end plate, and the rope end assembly is connected to the rope end mounting hole. The rope end plate is used to fix the rope end assembly of the traction rope; it is located at the lower part and corresponds to the extension direction of the traction rope.

[0010] Compared with the prior art, this utility model has the following advantages and effects: This design is an improvement on the load-bearing beam structure of an elevator, which can achieve symmetrical universal installation, is suitable for shaft spaces with symmetrical installation requirements, improves the construction efficiency of elevator installation, reduces the number of types of production components, reduces production costs, and improves economic benefits.
