[0042] Example 1:

[0043] refer to Figures 1 to 10 As shown in the figure, a double-track elevator device is shown, which includes: several cars 1, main rails 3 and auxiliary guide rails 6.

[0044] Preferably, the main guide rail 3 and the auxiliary guide rail 6 are two symmetrically arranged guide rails, and the main guide rail 3 and the auxiliary guide rail 6 are staggered in space.

[0045] Preferably, the main rail 3 is vertically arranged and fixed to the outside of the building to provide a support structure for the lifting of the car 1. For example, the main rail 3 is fixedly connected to each structural floor of the building through a number of cantilevered steel beams 11.

[0046] Preferably, reference Figure 3 and Figure 4 As shown, the main rail 3 is composed of several movable rails 301 and fixed rails 302. The movable rails 301 can be separated from the main rail 3, and the fixed rails 302 can be fixedly connected to the structural floor plates of the building through cantilevered steel beams 11.

[0047] Furthermore, the movable guide rail 301 and the fixed guide rail 302 are fixed in relative position via the guide rail buckle 303. For example, when the guide rail buckle 303 is released, the movable guide rail 301 and the fixed guide rail 302 can be separated.

[0048] Furthermore, the fixed guide rails 302 are located at corresponding positions of each structural floor plate 4 of the building, and the movable guide rails 301 are located between each structural floor plate 4. That is, the guide rails of the main rails 3 located between each structural floor plate 4 are movable and separable.

[0049] Preferably, the auxiliary guide rail 6 is provided on the bottom side of each structural floor plate 4. It can be used to provide mechanical support for the car 1 to enter each floor of the building.

[0050] Preferably, the rack on the auxiliary guide rail 6 faces the top or bottom side of the building. In addition, the end of the auxiliary guide rail beam 5 is provided with an L-shaped limit structure, through which the depth of the car 1 entering each floor of the building is controlled.

[0051] When the rack on the secondary guide rail 6 faces the bottom side of the building, the secondary guide rail 6 is laid on the bottom side of the secondary guide rail 6 beam 5 and is connected to the structural floor slab 4 through the secondary guide rail 6 beam 5.

[0052] That is, when the rack on the secondary guide rail 6 faces the bottom of the building, the secondary guide rail 6 only provides horizontal force support for the car 1 to enter the floor. The weight of the car 1 is provided by other supporting structures. For example, the bottom end of the car 1 is equipped with a wheel structure to support the car 1 sliding on the cantilevered steel beam 11.

[0053] Preferably, the elevator car 1 is provided with a main gear mechanism 7 , a sub-gear mechanism 8 , a position-compensating guide rail 9 , a position-limiting structure 10 and an electric motor 12 .

[0054] Preferably, the main gear mechanism 7 is arranged on both sides of the car, and the sub-gear mechanism 8 is located on the gear base 2 at the top of the car. The main gear mechanism 7 on the car 1 interacts only with the main guide rail 3, and the sub-gear mechanism 8 interacts only with the sub-guide rail. The two gear mechanisms do not operate simultaneously. The electric motor 12 is used to provide gear rotation power for the main gear mechanism 7 and / or the sub-gear mechanism 8.

[0055] Preferably, each car 1 is movably fixed on the main rail 3, and the main gear mechanism 7 is engaged with the rack on the outer side of the main rail 3, and the main gear mechanism 7 provides the car 1 with a driving force for ascending or descending.

[0056] Preferably, when the car 1 passes through each structural floor plate 4, the sub-gear mechanism 8 engages with the rack of the sub-guide rail 6 at the corresponding floor plate position, so that when necessary, the sub-gear mechanism 8 can drive the car 1 to enter the corresponding floor by rotation, and when it is not necessary to enter the corresponding floor, the sub-gear mechanism 8 can directly rotate to pass through the corresponding floor.

[0057] Preferably, the position-replacing guide rail 9 is located on the outer side wall of the car 1 , and the position-replacing guide rail 9 is parallel to each movable guide rail 301 and is arranged with the same length.

[0058] Furthermore, when the elevator car 1 reaches a predetermined floor, the auxiliary gear mechanism 8 engages with the rack of the auxiliary guide rail 6 on the top structural floor plate 4 of the corresponding floor, and the movable guide rail 301 and the fixed guide rail 302 at the corresponding position are disconnected. The auxiliary gear mechanism 8 completes the lateral displacement of the elevator car 1, allowing the elevator car 1 to enter the corresponding floor.

[0059] Furthermore, after the car 1 enters the floor, the replacement guide rail 9 on the outer wall of the car 1 completes the position on the main rail 3 that is missing due to the movable guide rail 301, thereby ensuring the structural integrity of the main rail 3, so that the remaining cars 1 on the main rail 3 can pass through the corresponding floors smoothly.

[0060] Preferably, the limiting structure 10 is clamped on the main rail 3, and the limiting structure 10 ensures that the car 1 can always be fixed on the main rail 3 during the movement.

[0061] Furthermore, if Figure 6 As shown, the limiting structure 10 includes a first bracket and a first roller 13 . One end of the first bracket is fixedly connected to the car 1 , and the other end is provided with a first roller 13 . The first roller 13 contacts the inner wall of the main guide rail 3 .

[0062] The structural design of the device of the present invention solves the problem of low material transport efficiency of conventional material hoists, meets the needs of simultaneous construction on multiple floors, and shortens the material lifting cycle on each floor. In particular, it significantly improves construction efficiency when constructing super-high-rise buildings.

[0063] Example 2

[0064] Based on Example 1, Figure 11 This embodiment discloses a double-track elevator device.

[0065] Among them, the rack on the auxiliary guide rail 6 faces the top side of the building, the auxiliary guide rail 6 is laid on the top side of the auxiliary guide rail beam 5, the auxiliary guide rail 6 beam 5 is connected to the bottom side of the structural floor plate 4 through a lifting bracket, and the distance between the auxiliary guide rail 6 and the structural floor plate 4 is greater than the size of the auxiliary gear mechanism 8.

[0066] Thus, the car 1 can be suspended to each floor via the auxiliary guide rail 6. The auxiliary guide rail 6 not only provides horizontal force support for the car 1 to enter the floor, but also provides vertical support for the car 1 to overcome gravity, thereby simplifying the support structure required for the car 1 to enter the floor.

[0067] Example 3

[0068] On the basis of Example 1 and Example 2, refer to Figures 12 to 14This embodiment discloses a double-track elevator device.
