Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a machine room-less machine beam structure. Background Art

[0002] In the prior art, when designing an elevator system, a standard structure is usually used to adapt to a car and a counterweight of a specific size. This design method has the following problems:

[0003] 1. The depth requirements for small cars are relatively strict: Due to the limitation of the standard structure, the entire counterweight sheave is always in front of or behind the center of the traction wheel, so the counterweight device and the entire elevator will require more space on this side. When half of the car depth is less than half of the length of the counterweight block plus the radius of the counterweight sheave, more space is needed in the front or back of the car; at this time, it is necessary to reduce the length of the counterweight block or reduce the depth of the car to shift the center of the car to one side to make room for the counterweight device; ultimately, the available space in the car is further reduced;

[0004] 2. Fixed door opening position: In standard structures, the door opening is usually located to one side and cannot be flexibly adjusted according to actual needs, such as being centered;

[0005] 3. Space utilization needs to be improved: The available car depth of the existing standard structure is small, which means that the maximum space utilization cannot be achieved within the limited shaft space.

[0006] Therefore, the existing standard structure has certain limitations in elevator design, especially when pursuing higher space utilization and more flexible design options. Utility Model Content

[0007] The purpose of the utility model is to provide a machine room-less machine beam structure. The utility model has the characteristics of small space occupation and uniform structural force.

[0008] The technical solution of the utility model is: a machine room-less shelf beam structure, including a pair of correspondingly arranged shelf beams, a shelf plate erected above the shelf beams, and a pair of counterweight rope head plates arranged at the lower part of the shelf beams and corresponding to the shelf plates; each of the shelf beams is a groove-type structure; the counterweight rope head plates are distributed on both sides of the shelf plates.

[0009] In the aforementioned machine room-less rack beam structure, a plurality of vertically arranged reinforcing plates are evenly distributed between the two rack beams.

[0010] In the aforementioned machine room-less shelf beam structure, a plurality of mounting holes for installation are evenly distributed on the shelf board; a plurality of reinforcing ribs connected to the outer side of the shelf beam are provided at the lower front portion of the shelf board; each of the reinforcing ribs is triangular in shape; the shelf board is H-shaped, and rope threading grooves are provided at the front and rear of the shelf board.

[0011] In the aforementioned machine room-less machine beam structure, the counterweight rope head plate is symmetrically arranged in the center with respect to the traction wheel.

[0012] Compared with the prior art, the utility model is composed of a shelf beam, a shelf plate and a pair of counterweight rope head plates, and the counterweight rope head plates are distributed on both sides of the shelf plate;

[0013] For machine room-less elevators, when the shaft depth is small, compared with the traditional structure, this application can provide sufficient space for the operation of the counterweight device; when through doors and eccentric door opening occur together, the floor door sill and car door sill can be effectively avoided;

[0014] By applying the present application, the lifting force on the counterweight wheel is symmetrical on the left and right, and the force on the structure is more uniform. Compared with the original counterweight device that concentrates the force on one point, the force can be effectively dispersed.

[0015] This application provides greater design flexibility by optimizing the size and layout of the counterweight blocks to adapt to different building requirements and space constraints.

[0016] In summary, the utility model has the characteristics of small space occupation and uniform structural force. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the utility model;

[0018] Figure 2 It is a top view of the utility model.

[0019] The markings in the attached drawings are: 11-shelf beam, 12-reinforcement plate, 2-shelf plate, 21-reinforcement rib, 22-mounting hole, 23-rope threading groove, 3-counterweight rope head plate. DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0021] Embodiment. A machine room-less machine beam structure, comprising: Figure 1 and 2 As shown, it includes a pair of corresponding shelf beams 11, a shelf plate 2 erected above the shelf beams 11, and a pair of counterweight rope head plates 3 arranged at the lower part of the shelf beams 11 and corresponding to the shelf plates 2; each of the shelf beams 11 is a groove-type structure; the counterweight rope head plates 3 are distributed on both sides of the shelf plates 2.

[0022] A plurality of vertically arranged reinforcing plates 12 are evenly distributed between the two shelf beams 11 .

[0023] The shelf board 2 is evenly distributed with a plurality of mounting holes 22 for installation; a plurality of reinforcing ribs 21 connected to the outer side of the shelf beam 11 are provided at the lower front portion of the shelf board 2; each of the reinforcing ribs 21 is triangular in shape; the shelf board 2 is H-shaped, and rope threading grooves 23 are provided at the front and rear of the shelf board 2 accordingly.

[0024] The mounting hole 22 is used for mounting a shock-absorbing pad.

[0025] The counterweight rope head plate 3 is symmetrically arranged in the center with respect to the traction wheel.

[0026] Under the same car size, this application has smaller requirements on the shaft depth than the standard structure, and the selectable counterweight sizes are more abundant. By selecting a longer counterweight, there are fewer restrictions on the car width (a wider car can be selected), the door position (whether the door is centered / eccentric to one side under the same door width), and the shaft side wall space, providing more choices.

[0027] The space utilization rate is higher. With the existing standard structure, when the same counterweight is selected, the selectable car width is the same as that of the present application, and the selectable car depth is smaller than that of the present application. When the shaft space is not ample, a more spacious car can still be selected as much as possible.
