[0034] The elevator has the advantages that the first door 330 and the second door 340 are arranged on the first side and the second side of the car 300 respectively, so that the car 300 has a structure of a right-angle double door, one end of the first guide assembly 100 and one end of the second guide assembly 200 are arranged in the pit of the hoistway, the other end of the first guide assembly 100 and the other end of the second guide assembly 200 extend along the height direction of the hoistway, the traction assembly 400 arranged on the force receiving assembly can drive the car 300 and the counterweight module to reciprocate along the extension direction of the first guide assembly 100 and the extension direction of the second guide assembly 200 respectively, so as to realize the lifting of the car 300, in this process, the first guide assembly 100 can not only provide a guide function for the car 300, but also transmit the weight of the car 300 to the pit of the hoistway through the first guide assembly 100, similarly, the second guide assembly 200 can not only provide a guide function for the counterweight module, but also transmit the weight of the counterweight module to the pit of the hoistway through the second guide assembly 200, the first fixed beam 610 is connected with the second fixed beam 620 through the reinforcing beam 630, so as to improve the mounting strength of the first fixed beam 610 and the second fixed beam 620, and further improve the mounting strength of the first guide assembly 100 and the second guide assembly 200, and the elevator does not need to be supported by the sidewall of the hoistway; compared with the prior art, the elevator does not need to design a structure for bearing the weight of the elevator in the elevator hoistway in advance, so as to reduce the construction cost.

[0035] Further, the first door 330 and the second door 340 are arranged on the first side and the second side of the car 300 respectively, so that the car 300 has a structure of a right-angle double door, thereby facilitating passengers to enter and exit the car 300 from different directions. In the prior art, for the elevator with a structure of a right-angle double door, the arrangement and structural design of the elevator are difficult, in the application, the traction assembly 400 arranged on the force receiving assembly can drive the car 300 and the counterweight module to reciprocate along the extension direction of the first guide assembly 100 and the extension direction of the second guide assembly 200 respectively, so as to realize the lifting of the car 300, and the mounting strength is high and the structure is stable.

[0036] As an explanation, one end of the first guide assembly 100 is arranged in the pit of the hoistway, and the other end extends along the height direction of the hoistway, the car 300 is arranged on the first guide assembly 100 and is lifted under the driving of the traction assembly 400, in this process, neither the first guide assembly 100, the second guide assembly 200, the car 300 nor the traction assembly 400 is in contact with the sidewall of the hoistway, and the sidewall of the hoistway does not support the first guide assembly 100, the second guide assembly 200, the car 300 and the traction assembly 400, therefore, when the building is under construction, it is not necessary to design a load-bearing structure in the elevator hoistway of the building, thereby reducing the construction cost.

[0037] The traction assembly 400 is arranged on the force receiving assembly and is used to provide power for the lifting of the car 300; further, the traction assembly 400 pulls the car 300 and the counterweight module for lifting through the traction rope 420 and the like.

[0038] Further, in the embodiment, since the elevator does not contact the sidewall of the hoistway, the vibration and noise generated by the elevator during operation of the elevator cannot be transmitted to the living room of the building through the sidewall of the hoistway, thereby improving the living experience.

[0039] In one embodiment, the first guide assembly 100 includes a guide column arranged in the hoistway pit; further, in order to ensure the guiding stability and load bearing stability of the first guide mechanism, the guide column is provided with at least two and is arranged along the outer periphery of the car 300.

[0041] The first guide 110 and the second guide 120 are arranged opposite to the first and second corners 310 and 320 of the car 300 respectively, and the opposite ends of the guide matching piece 500 arranged on the car 300 are guided and matched with the first and second guides 110 and 120 respectively, which not only improves the lifting stability of the car 300, but also prevents the car 300 from being subjected to unbalanced load during operation, so that the stress condition of the overall structure is more stable and reliable.

[0042] Please refer to Figures 1 to 3 In one embodiment, the first guide 110 includes a first guide column, and the second guide 120 includes a second guide column, one end of the first guide column and one end of the second guide column are arranged in the hoistway pit in a spaced manner, the other end of the first guide column and the other end of the second guide column extend in the height direction of the hoistway, the first guide column is arranged at a position opposite to the first corner 310, the second guide column is arranged at a position opposite to the second corner 320, and the first guide column and the second guide column are parallel to each other, and the opposite ends of the guide matching piece 500 can be guided and matched with the first and second guide columns respectively, thereby providing more stable guidance for the car 300.

[0043] Please refer to Figures 1 to 3In one embodiment, the traction assembly 400 comprises a traction rope 420 and a traction machine 410, one end of the traction rope 420 is arranged on the first fixed beam 610, the other end of the traction rope 420 and the traction machine 410 are arranged on the second fixed beam 620, the guide matching part 500 is arranged on the top plate of the car 300 and is provided with a first counterweight 510, the counterweight module is provided with a second counterweight (not shown in the figure), and the traction rope 420 is sequentially wound around the first counterweight 510, the traction wheel 412 of the traction machine 410 and the second counterweight.

[0045] Further, the traction machine 410 is provided with a traction wheel 412, the traction rope 420 is sequentially wound around the first counterweight 510, the traction wheel 412 and the second counterweight, when the traction wheel 412 rotates, it drives the traction rope 420 to move, at this time, the length of the traction rope 420 on the upper part of the first counterweight 510 is elongated or shortened, and correspondingly, the length of the traction rope 420 on the upper part of the second counterweight is shortened or elongated; when the length of the traction rope 420 on the upper part of the first counterweight 510 is elongated and the length of the traction rope 420 on the upper part of the second counterweight is shortened, the car 300 descends and the counterweight module ascends, when the length of the traction rope 420 on the upper part of the first counterweight 510 is shortened and the length of the traction rope 420 on the upper part of the second counterweight is elongated, the car 300 ascends and the counterweight module descends, the counterweight module can balance the weight of the car 300, thereby reducing the operating burden of the traction machine 410.

[0046] As an explanation, the elevator is generally divided into single-door elevator, through-type elevator and right-angle double-door elevator, among them, the single-door elevator is only provided with a car door on one side of the car 300, the through-type elevator is provided with car doors on opposite two sides of the car 300 respectively, and the right-angle double-door elevator is provided with car doors on adjacent two sides of the car 300 respectively (i.e. the first car door 330 and the second car door 340 in the above embodiment), because of the special layout of the car doors of the right-angle double-door elevator, in order to avoid the conflict between the direction of the car door and the position of other components in the elevator, the design difficulty of the right-angle double-door elevator is greater, and the cost is higher. In one embodiment, please refer to Figure 3The first guide 110 is arranged at a position opposite to the first corner 310, the second guide 120 is arranged at a position opposite to the second corner 320, and the second guide assembly 200 for guiding the counterweight module is arranged at a position opposite to one side of the car 300 (the side is not arranged with a door), so that the layout of the doors of the car 300 is not affected, and the car 300 is guided more stably.

[0047] Please refer to Figure 1 In an embodiment, the first door 330 is arranged at a side of the car 300 away from the second guide assembly 200, and the second door 340 is arranged at an adjacent side.

[0048] Further, when the right-angle double-open door elevator is a sightseeing elevator, the car 300 is made of transparent glass, and in the embodiment, the first guide assembly 100, the traction assembly 400, the counterweight module and the second guide assembly 200 do not affect the view of the sightseeing elevator.

One end of the traction rope 420 away from the first fixed beam 610 is arranged on the mounting bracket 700.

[0050] The mounting bracket 700 is connected with the second fixed beam 620 through the first connecting portion 710 and the second connecting portion 720, so as to provide a mounting position for one end of the traction rope 420 away from the first fixed beam 610, and ensure the mounting reliability of the traction rope 420.

[0051] Please refer to Figures 1 to 3 In an embodiment, the traction machine 410 comprises a machine shell 411 and a driving member, the machine shell 411 is arranged on the second fixed beam 620, the traction wheel 412 is rotatably arranged in the machine shell 411, and the driving member is arranged on the machine shell 411 and is drivingly connected with the traction wheel 412.

[0052] The machine shell 411 can protect the traction wheel 412 to a certain extent, prevent dust and other impurities from affecting the normal operation of the traction wheel 412, and the driving member can drive the traction wheel 412 to rotate, so as to drive the car 300 to ascend and descend.

[0053] Please refer to Figures 1 to 3In one embodiment, the traction assembly 400 further comprises a first guide wheel 430 and a second guide wheel 440, the first guide wheel 430 is rotatably arranged on the first fixed beam 610, and the second guide wheel 440 is rotatably arranged on the second fixed beam 620, the second guide wheel 440 is arranged on the side of the traction sheave 412 facing the counterweight module, and the traction rope 420 is sequentially wound around the first reverse sheave 510, the first guide wheel 430, the second guide wheel 440, the traction sheave 412, and the second reverse sheave.

[0054] After the traction rope 420 is wound around the first reverse sheave 510 on the car 300, it is sequentially wound around the first guide wheel 430 arranged on the first fixed beam 610 and the second guide wheel 440 arranged on the second fixed beam 620 to limit the running route of the traction rope 420, thereby leaving additional space for installing other elements or mechanisms; in addition, the second guide wheel 440 is arranged on the side of the traction sheave 412 facing the counterweight module, when the traction rope 420 is wound around the second guide wheel 440 and then wound around the traction sheave 412, the contact area between the traction rope 420 and the traction sheave 412 is increased, thereby increasing the friction between the traction rope 420 and the traction sheave 412, preventing the traction rope 420 and the traction sheave 412 from sliding and affecting the normal operation of the elevator.

[0055] Please refer to Figures 1 to 3 In one embodiment, flat steel belts are used as the traction rope 420; in order to ensure the service life of the traction rope 420, it is required that the ratio of the diameter of all sheaves in the elevator to the cross-sectional diameter of the traction rope 420 is not less than 40, and the flat steel belts not only have high strength, but also have relatively small thickness, therefore, the diameter of the sheaves that can be used is also relatively small, and thus the top floor height and pit depth of the building required are also relatively small, which can fully utilize the hoistway space.
