According to a more inferior embodiment, the first rail 8, the second rail 9, and the third rail 10 can also be arranged on the same side of the main body assembly.

[0039] In order to ensure the distance between the first rail and the planes formed by the second rail and the third rail, the main body assembly of the present utility model is further provided with a side beam structure. The extending direction of the side beam structure is perpendicular to the upper beam 3 and the rails, and the rails are fixed on the upper beam 3 and the lower beam 5 through the side beam structure.

[0040] Specifically, multiple rails include a second rail 9 and a third rail 10. The side beam structure includes two first side beams 2 and two second side beams 6.

[0045] The plurality of tracks include a first track 8, a second track 9 and a third track 10. Among them, the second track 9 and the third track 10 are respectively located at opposite ends of the main body component. The first track 8 is arranged on one side of the main body component close to the second track 9 or close to the third track 10, that is, although the first track is arranged between the second track and the third track, it is not in the middle position (its position is determined by the relative positions of the traction machine overhead beam and the counterweight wheel), or in other words, the first track is not arranged at the middle position of the upper beam or the lower beam. The first track is either closer to the second track or closer to the third track. The second track 9 and the third track 10 are used to install the counterweight, and the first track is used to install the car.

[0046] According to the second embodiment of the present invention, there is also provided a construction elevator in a hoistway, which includes a plurality of the above-mentioned track quick-installation modules.

The counterweight 13 is movably arranged between the second track 9 and the third track 10 to move along the extending direction of the track; the car 14 is movably arranged between the first track 8 and the fourth track and moves along the extending direction of the track.

[0047] Specifically, a second guide shoe 12 is fixed to the outer surface of the second track 9, and a second counterweight frame 121 is fixed to the outer surface of the second guide shoe 12. A first guide shoe 11 is fixed to the outer surface of the third track 10, and a first counterweight frame 111 is connected to the outer surface of the first guide shoe 11.

[0048] This embodiment is a track quick-installation module for a construction hoist in a hoistway, including:

[0049] A main body assembly, which includes a middle side beam 1, a first side beam track 2, an upper beam 3, a middle beam 4, a lower beam 5, and a second side beam 6;

[0050] The first side beam 2 is arranged directly below the middle side beam 1, the second side beam 6 is arranged directly above the middle side beam 1, the upper beam 3 is fixed to one side of the outer surface of the second side beam 6, the middle beam 4 is fixed to one side of the outer surface of the middle side beam 1, and the lower beam 5 is fixed to one side of the outer surface of the first side beam 2;

[0051] The upper beam 3 is fixed to the outer side surface of the second side beam 6, and the middle beam 4 and the lower beam 5 respectively extend outward and are fixed on the outer side surface of the first side beam 2. This layout enhances the lateral stability of the entire guide rail system and provides a solid foundation for the installation of the guide rails;

[0052] A diagonal web member 7 passes through the middle of the middle beam 4, a first track 8 is fixedly installed on one side of the outer surface of the upper beam 3, a second track 9 is fixed to one side of the outer surface of a group of middle side beams 1, and a third track 10 is fixed to one side of the outer surface of another group of middle side beams 1;

[0053] A diagonal web member 7 passes through the middle of the middle beam 4. This design is to increase the mechanical stability of the entire structure and prevent deformation caused by load changes;

[0054] Working principle:

[0055] The three guide rails, namely the first track 8, the second track 9, and the third track 10, are processed to the same length on a special machine tool and then connected to other components on a process jig to form a cuboid module. Among them, the second track 9 and the third track 10 are counterweight rails, and the first track 8 is the main track for the car 14 to run. The relative positions of the three tracks are fixed and the models are the same. Once the position of any one of them is determined, the positions of the other two can be determined.

[0056] The above three tracks are connected into an integral module through the main body component. Therefore, during wire laying, it is only necessary to roughly measure the size of the hoistway, hang a plumb line with any one of the tracks in the module as a reference, and the relative positions of other components can be determined quickly and very accurately without making a wire laying module.

[0057] Meanwhile, after the position of the module is determined, the position and verticality of the other main track can also be determined quickly. The installation speed is fast, and there is no need to transport, transfer, measure, position, reinforce, and adjust the tracks one by one.

[0058] By adopting the design and installation method of the integral module for this step, it can not only significantly improve the installation speed and accuracy, but also save manpower and material resources while improving the quality of the installation work and the overall performance of the elevator.

[0059] In the description of the present utility model, it should also be noted that unless otherwise clearly specified and defined, the terms "set", "install", "connect", and "couple" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0060] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
