[0002] Currently, there is usually only one elevator shaft, and the elevator shaft is constructed in advance before a civil engineering survey is conducted. Then, an elevator assembly suitable for the shaft is laid out for the customer's daily use. However, in actual operation, the size of the elevator shaft is limited, resulting in customer needs not being met, or the elevator structure is unreasonable due to the shaft structure, which increases the difficulty of elevator maintenance and reduces the service life of the elevator. If there is a way to split a single shaft layout into multiple shaft layouts, that is, to split the elevator components into each independent shaft, and the elevator components operate independently in each independent shaft, it is bound to reduce the elevator structure's dependence on the shaft layout. Therefore, it is very necessary to develop a multi-shaft elevator layout to meet customers' requirements for the largest car size in the existing elevator shaft and stable operation.

DETAILED DESCRIPTION

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0035] like Figure 1 、 Figure 2 As shown, the multi-hoistway elevator arrangement structure 100 provided in the present application includes a main hoistway 10, a car 20, multiple counterweight hoistways 30, and multiple counterweights 40. The car 20 is installed in the main hoistway 10 so as to be liftable. The multiple counterweight hoistways 30 are arranged outside the main hoistway 10 and are independently arranged relative to the main hoistway 10. The multiple counterweights 40 correspond one-to-one to the multiple counterweight hoistways 30. The counterweights 40 are installed in the corresponding counterweight hoistways 30 so as to be liftable. Moreover, each counterweight 40 is respectively connected to the car 20 in a transmission manner. The multiple counterweights 40 can simultaneously perform lifting and lowering movements in the corresponding counterweight hoistways 30. Here, the multiple counterweights 40 are used together to balance the weight of the car 20 itself and the weight after loading.

[0036] As can be seen from the above, since the car 20 is arranged in the main shaft 10 and the counterweight 40 is arranged in the corresponding counterweight shaft 30, the size of the car 20 can match the size setting of the main shaft 10. In this way, the multi-shaft elevator layout structure 100 can greatly improve the shaft utilization rate of the main shaft 10 without improving the size structure of the main shaft 10, and reduce the initial erroneous construction cost; in addition, a separate counterweight shaft 30 is used to accommodate the counterweight 40, which not only expands the installation space of the counterweight 40, but also reduces the manufacturing cost of the counterweight 40.

[0037] It should be noted that the above-mentioned main shaft 10 is pre-built. If the main shaft 10 cannot meet the requirements of the elevator design layout, there is no need to demolish the originally built main shaft 10. Instead, it is only necessary to expand the counterweight shaft 30 outside the main shaft 10 to complete the design plan desired by the owner; especially when the main shaft 10 of a sightseeing elevator has been built but cannot meet the owner's space requirements, a counterweight shaft 30 can be built near the main shaft 10, and the counterweight 40 can be split into the corresponding counterweight shaft 30. In this way, the shaft utilization rate of the main shaft 10 can be greatly improved without damaging the main shaft 10, and the elevator can be made more beautiful when running.

[0038] like Figure 1 、 Figure 2 As shown, in one embodiment, the spacing between the counterweight shaft 30 and the main shaft 10 can be adjusted, so that the location of the counterweight shaft 30 can be selected according to the actual site conditions. This can reduce the requirements for the construction location of the counterweight shaft 30, thereby increasing the feasibility of the elevator design solution to meet the requirements of the owner. Here, the spacing between the counterweight shaft 30 and the main shaft 10 specifically refers to the distance between the counterweight shaft 30 and the main shaft 10 in the horizontal direction.

[0039] like Figure 1 、 Figure 2 As shown, in one embodiment, the number of counterweight shafts 30 is configured to be two, and the two counterweight shafts 30 are symmetrically arranged on the left and right sides of the main shaft 10. In other words, this elevator solution adopts a symmetrical double counterweight, and the two counterweights 40 can run in the counterweight shafts 30 on both sides, either upward or downward, for a symmetrical and beautiful appearance. It is understood that in other embodiments, the two counterweight shafts 30 can also be arranged asymmetrically relative to the main shaft 10 according to on-site civil engineering requirements, or the number of counterweight shafts 30 can be configured to be three, four, or even more. Moreover, the counterweight shafts 30 can be adaptively arranged according to on-site civil engineering requirements, which will not be elaborated here.

[0040] It should be noted that, at present, the existing double-counterweight elevator shafts are all single and independent, that is, one elevator shaft is used to accommodate the car and two counterweights at the same time. When the owner needs a double-counterweight elevator, the existing elevator shaft is often unable to meet the design requirements. This is because the layout of the double-counterweight sightseeing elevator has very high requirements for the width of the sightseeing shaft, and general civil construction cannot take this into account. Obviously, the solution of this application is to build two additional counterweight shafts in addition to the original main shaft, so that the three elevator shafts form a whole to complete the double-counterweight elevator solution without the need for large-scale demolition and reconstruction, which can be the most economical and feasible.

[0041] like Figure 3 、 Figure 4As shown, the multi-hoistway elevator arrangement 100 also includes multiple traction rope groups 51, each corresponding one-to-one to a plurality of counterweights 40, and each traction rope group 51 can be transmission-connected to the corresponding counterweight 40. The multiple traction rope groups 51 can be combined into a traction rope assembly 510, which is transmission-connected to the car 20. In other words, the traction rope assembly 510 on the car 20 can be divided into a plurality of traction rope groups 51, the same number as the counterweights 40, and each traction rope group 51 is transmission-connected to the counterweight 40. This can meet the requirements for transmission connection between the car 20 and the plurality of counterweights 40. Here, the main hoistway 10 and the plurality of counterweight hoistways 30 are connected and formed with a wire threading channel 101, through which the corresponding traction rope groups 51 can pass. It should be noted that the traction rope group 51 can be formed by a combination of multiple steel ropes.

[0042] like Figure 3 、 Figure 4 As shown, each counterweight 40 is mounted with a counterweight wheel 41. One end of a traction rope assembly 51, after passing through the corresponding counterweight wheel 41, is secured within the corresponding counterweight shaft 30, thereby establishing a transmission connection between the traction rope assembly 51 and the corresponding counterweight 40. In other words, the traction rope assembly 51 is capable of lifting the counterweight 40 via the counterweight wheels 41 and controlling the vertical movement of the counterweight 40 within the counterweight shaft 30. Here, each counterweight 40 is mounted with one counterweight wheel 41. It is understood that in other embodiments, each counterweight 40 may be mounted with multiple counterweight wheels 41, which will not be discussed in detail here.

[0043] like Figure 3 、 Figure 4 As shown, the car 20 is equipped with car wheels 21. One end of the traction rope assembly 510, after being wound around the corresponding car wheel 21, is fixed to the main shaft 10, thereby connecting the traction rope assembly 510 to the car 20. In other words, the traction rope assembly 510 can lift the car 20 via the car wheels 21 and control the lifting and lowering movement of the car 20 within the main shaft 10. Here, the car 20 is equipped with two car wheels 21. It is understood that in other embodiments, the number of car wheels 21 installed on the car 20 can also be three, four, or even more, which will not be elaborated here.

[0044] like Figure 3 、 Figure 4 As shown, the multi-hoistway elevator arrangement structure 100 further includes a guide sheave 52. After passing through the guide sheave 52, the multiple traction rope groups 51 are combined into a traction rope assembly 510. It should be noted that the specific structure of the guide sheave 52 and the working principle of combining the multiple traction rope groups 51 passing through the guide sheave 52 into the traction rope assembly 510 can adopt existing conventional methods and will not be elaborated here.

[0045] like Figure 3 、 Figure 4 As shown, the multi-hoistway elevator arrangement 100 also includes a main engine 53, which is drivingly connected to a main engine pulley 531. The traction rope assembly 510 is drivingly connected to the car 20 after passing through the main engine pulley 531. In other words, the main engine 53 can drive the traction rope assembly 510 via the main engine pulley 531 to provide power for the car 20 to move up and down within the main hoistway 10. Here, the main engine 53 is fixedly installed within the main hoistway 10, so that the installation of the main engine 53 does not occupy additional space.

[0046] like Figure 3 、 Figure 4 As shown, the multi-shaft elevator arrangement structure 100 also includes a plurality of return rope pulley groups 54, and the plurality of return rope pulley groups 54 correspond one to one with the plurality of traction rope groups 51; wherein, each return rope pulley group 54 includes two return rope pulleys 541, and one of the return rope pulleys 541 is fixed in the counterweight shaft 30, and the main shaft 10 is connected with the plurality of counterweight shafts 30 and a threading channel 101 is formed, and the threading channel 101 can be used for the corresponding traction rope group 51 to pass through, and the other return rope pulley 541 in each return rope pulley group 54 is fixed in the main shaft 10 or in the threading channel 101, so that the use requirement of merging the plurality of traction rope groups 51 with the guide split rope pulley 52 can be met.

[0047] In one specific embodiment, Figure 3 、 Figure 4As shown, the guide sheave 52 is arranged below the main pulley 531, and the return sheave group 54 is arranged above the main pulley 531. After the traction rope assembly 510 is wound around the main pulley 531, it is first wound downwardly around the guide sheave 52 and then wound upwardly around the return sheave group 54, so that the traction rope group 51 is guided to the top of the shaft, so that it can pass through the top threading channel 101 and enter the counterweight shaft 30. That is, the main shaft 10 and the counterweight shaft 30 are connected to each other at the top. Specifically, the main machine 53 is installed on the main machine base, which is arranged on the shaft wall of the main shaft 10 near the counterweight shaft 30. The guide sheave 52 is installed at the bottom of the main machine base. The guide sheave 52 and the car 20 are respectively located on both sides of the main pulley 531, and the car pulleys 21 are provided at both ends of the top of the car 20. Therefore, the traction system of the elevator is arranged at the top of the shaft, saving bottom space. Preferably, the traction rope assembly 510 is wound around the main wheel 531 and then vertically downwards around the car wheel 21 close to the main wheel 531; each return rope pulley group 54 includes two return rope pulleys 541, one of which is fixed in the counterweight shaft 30, and the other return rope pulley 541 in each return rope pulley group 54 is respectively fixed in the main shaft 10 and the threading channel 101, and the return rope pulley group 54 is arranged horizontally; the traction rope group 51 is wound vertically upwards around the return rope pulley 541 in the main shaft 10 by the guide split rope pulley 52, and the traction rope group 51 between the guide split rope pulley 52 and the return rope pulley 541 in the main shaft 10 is arranged close to the main wheel 531; the return rope pulley 541 in the counterweight shaft 30 is arranged close to the counterweight wheel 41; this design saves space in the main shaft 10 and the counterweight shaft 30, and increases the wrap angle of the traction rope group 51 around each wheel, thereby improving the traction force.

[0048] The technical features of the above embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
