Description

Technical Field

[0001] The utility model relates to the technical field of household elevators, in particular to a duplex elevator. Background Art

[0002] An elevator is a fixed lifting device that serves specified floors. In order to meet the use requirements of high-rise residential buildings, office buildings, hotels, etc., ordinary elevators are generally heavy-duty and high-speed. In home villa elevators, the requirements for aesthetics and comfort are higher, so stable, noiseless, power-saving, pollution-free, simple and machine-room-free platform elevators are becoming more and more popular among users.

[0003] As people's living standards continue to improve, the requirements for quality of life are also getting higher and higher. Users living in duplexes and stacked villas are beginning to consider installing elevators between the first and second floors, especially platform elevators. Duplexes in high-rise residential buildings are generally composed of the top floor and the second to last floor, which are actually off the ground. Stacked villas are essentially a type of duplex. Its total number of floors is usually four or six floors. Generally, there is one household on every two floors, so the six-story stacked villa can be divided into upper, middle and lower floors. Although traditional duplexes or stacked villas have space for installing elevators, it is not as easy to install elevators in the upper and middle floors of duplexes or stacked villas in high-rise buildings as it is to install elevators directly on the ground floor, because there are other residents downstairs and the floor slab is shared. If it is the middle floor of a stacked villa, there are other residents downstairs and upstairs. In addition to the feasibility of the installation space, the stress of the floor slab must be fully considered.

[0004] The force of traditional platform elevators is generally on the ground. This installation method is obviously not suitable for the aforementioned duplex structure except for the lower stack. It does not meet the industry standards for safety performance or elevator installation. In the prior art, in most cases, the ground where the hoistway needs to be added is reinforced on the first floor of the duplex, and then bricks are laid to make a brick-concrete structure of the hoistway. This method reinforces the location where the elevator is installed. On the surface, it seems to increase the corresponding strength, but it does not change the bearing capacity of the original floor. On the contrary, the stress of the original floor will be increased due to the reinforced structure. In other words, once the elevator control system fails and exceeds the bottom or top floor, it is still possible that the elevator will penetrate the floor due to squatting or rushing to the top, affecting other residents and even causing unnecessary disputes. On the other hand, in order to reduce the system quality and the weight of the equipment, most duplex plans will choose to remove the frame and its glass solution to meet the force requirements of the floor, which will inevitably bring major safety risks. Utility Model Content

[0005] In order to overcome at least one defect in the above prior art, the utility model provides a duplex elevator with a simple structure, easy to drive, and small force on the bottom floor, which will not cause safety hazards caused by excessive force on the bottom floor.

[0006] The utility model provides a duplex elevator, comprising a guide rail unit, a lifting unit and a traction rope, wherein the guide rail unit is fixed on an intermediate building ring beam and / or a top building ring beam, the lifting unit is liftably connected to the guide rail unit, a strong drive main unit is connected to the lifting unit, one end of the traction rope is wound on the strong drive main unit, and the other end of the traction rope is connected to the top building ring beam and / or the intermediate building ring beam.

[0007] Compared with the prior art, the duplex elevator of the utility model has the following advantages:

[0008] Compared with the prior art, the duplex elevator in the utility model borrows the middle building ring beam and the top building ring beam of the main structure of the house. The ring beam is generally a reinforced concrete building structure when the building is first built, which has high strength performance and strong bearing capacity; therefore, in this structure, the guide rail unit is fixed on the middle building ring beam and / or the top building ring beam, and the force of the guide rail unit is completely decomposed into the ring beam structure, which has nothing to do with the bottom floor slab, thereby reducing the force on the bottom floor slab; similarly, a reverse wheel is fixedly connected to the top ring beam, and is driven by the strong drive main engine on the lifting unit. The traction rope can be extended or retracted, and the other end of the traction rope is directly or indirectly connected to the top building ring beam and / or the middle building ring beam. During the operation of the strong drive main unit, the extension or shortening of the traction rope drives the entire lifting unit to descend or rise, that is, the elevator can go down or up. Compared with conventional counterweight elevators, the counterweight structure is omitted, the gravity is reduced, the driving structure is simplified, and the gravity of the lifting unit is decomposed to the top ring beam through the reverse wheel, which has nothing to do with the bottom floor slab, effectively solving the problem of safety hazards caused by excessive force on the bottom floor slab.

[0009] As an improvement, the guide rail unit includes two main rails, which are symmetrically distributed on both sides of the lifting unit, and the two main rails are fixed on the middle building ring beam and / or the top building ring beam.

[0010] In a further improvement, the tops of the two main rails are connected with a fixing seat, the fixing seat is connected with a reverse wheel, and the end of the traction rope away from the strong drive main engine bypasses the reverse wheel and is connected to the top building ring beam and / or the middle building ring beam. In the above improved structure, the reverse wheel is mainly set to solve the problem of unbalanced load, and is connected to the two main rails through the fixing seat. Its main force is transmitted to the top building ring beam and / or the middle building ring beam through the main rails, ensuring the stability, comfort and safety of the elevator operation.

[0011] In a further improvement, the fixing seat is connected to the top building ring beam. In the above improved structure, the fixing seat is further connected and fixed to the top ring beam to increase the strength of the fixing seat connection structure, further ensuring the stability and safety of the elevator operation.

[0012] In a further improvement, the lifting unit includes a mounting frame, the two sides of which are respectively connected to the two main rails in a liftable manner, the strong drive main unit is connected to the mounting frame, and the front side of the mounting frame is connected to an open manned platform or a closed car. In the above improved structure, the strong drive main unit is connected to the mounting frame, and the manned platform or car is connected to the front side of the mounting frame, which can balance gravity on the one hand, and on the other hand, this structural distribution is more convenient for the installation of the strong drive main unit.

[0013] In a further improvement, the lower end of the fixing seat is connected with a buffer member which is opposite to the top of the mounting frame and is used for anti-collision buffering. In the above improved structure, the buffer member is arranged to prevent the top of the mounting frame from directly hitting the fixing seat due to control failure during the elevator ascending process, thereby causing a safety accident.

[0014] Furthermore, it also includes a protection frame surrounding the outside of the lifting unit and the guide rail unit, the outer wall of the protection frame is connected to the middle building ring beam and / or the top building ring beam, and the bottom of the protection frame does not contact the bottom floor. In the above structure, the protection frame is provided to improve the safety performance of the elevator, especially when the front side of the mounting frame is connected to an open manned platform, the protection frame plays a role in directly protecting the user.

[0015] In a further improvement, the rear side wall of the protection frame is fixed to the middle building ring beam, and the left and right side walls and the front side wall of the protection frame are fixedly connected to the middle building floor. In the above improved structure, in the middle of the protection frame corresponding to the middle floor, in addition to the rear side being fixed to the middle building ring beam, the other side walls are also fixed to the middle floor, so as to avoid affecting the strength of the protection frame connection structure due to the force of the unilateral connection, ensure the stability of the protection frame connection structure, and improve the safety performance.

[0016] In a further improvement, the side plates of the protection frame are connected with sealing plates and floor doors. In the above improved structure, the addition of sealing plates further improves the safety performance, and the gravity of this structure is decomposed into the ring beam structure, which will not increase the stress on the bottom floor.

[0017] As a further improvement, the traction rope is any one of a steel wire rope, a steel belt or a chain.

[0018] Other improved features and advantages of the utility model will be described in the subsequent specific embodiments, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be achieved and obtained through the structures specifically pointed out in the description and the drawings.

[0024] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the embodiments of the present application, and are not intended to limit the protection scope of the embodiments of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0025] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "fixed" and "connected" 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 a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0026] In the embodiments of the present application, unless otherwise clearly specified and limited, the first feature at the "upper end" or "lower end" of the second feature may be such that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium.

[0027] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] See also Figure 1 to Figure 3As shown, an embodiment of the present application discloses a duplex elevator, comprising a guide rail unit, a lifting unit and a traction rope 1; wherein the guide rail unit is fixed on the middle building ring beam 2 and / or the top building ring beam 3, the bottom of the guide rail unit may or may not be in contact with the bottom floor, and the weight force point of the guide rail unit is on the top ring beam 3 and / or the middle ring beam 2, ensuring that the bottom floor is not subjected to force or is subjected to extremely small force, and will not affect the load-bearing capacity of the bottom floor.

[0029] In addition, the lifting unit is connected to the guide rail unit in a liftable manner, and a strong drive main unit 4 is connected to the lifting unit, one end of the traction rope 1 is wound on the strong drive main unit 4, and the other end of the traction rope 1 is connected and fixed to the top building ring beam 3 and / or the middle building ring beam 2. In this structure, the traction rope 1 is extended or shortened by the operation of the strong drive main unit 4, driving the lifting unit to descend or rise, thereby realizing the descent or ascent of the elevator. Among them, the traction rope 1 is any one of a steel wire rope, a steel belt or a chain. The strong drive main unit 4 in this structure is a mature prior art, which includes a strong drive motor and a winding drum. One end of the traction rope 1 is wound on the winding drum, and the winding drum is driven to rotate by the strong drive motor to realize the unfolding and winding of the traction rope 1, thereby driving the descent and ascent of the entire lifting unit.

[0030] Preferably, in this embodiment, the guide rail unit includes two main rails 6, which are symmetrically distributed on both sides of the lifting unit, and the two main rails 6 are fixed to the middle building ring beam 2 through corresponding connecting parts and expansion bolts. Since the lever arm at the connection position of the middle ring beam is small, the shaking caused during the operation of the elevator is small, thereby ensuring the structural stability.

[0031] In some other embodiments, the guide rail unit can be fixed on the top ring beam, or fixedly connected to the middle ring beam and the top ring beam at the same time. Simultaneous fixation can indeed better increase the strength of the connection structure, but the connection structure is more complicated, especially the difficulty of laying out the installation position at the top is increased, because corresponding fixing seats 7 need to be set on the top of the two main rails 6, which is explained below.

[0032] In addition, in order to solve the problem of unbalanced loading during elevator operation, in this embodiment, a fixed seat 7 is connected to the top of the two main rails 6, and a reverse wheel 5 is connected to the fixed seat 7. The end of the traction rope 1 away from the strong drive main unit 4 bypasses the reverse wheel 5 and is directly or indirectly connected to the top building ring beam 3 and / or the middle building ring beam 2 through other connecting parts.

[0033] In this embodiment, the lifting of the elevator is driven by the strong drive main engine 4. During the lifting process, the main gravity is concentrated on the reverse wheel 5, so the installation structure strength of the reverse wheel 5 is particularly important. For this reason, in addition to being connected to the top of the two main rails 6, the rear side wall of the fixed seat 7 is also connected and fixed to the top ring beam 3. Therefore, in this structure, the gravity of the lifting unit is decomposed to the top ring beam and the middle ring beam through the fixed seat 7, ensuring the stability and safety of the elevator operation.

[0034] In this embodiment, the lifting unit includes a mounting frame 8, and both sides of the mounting frame 8 are respectively connected to the two main guide rails 6 in a liftable manner. Specifically, guide shoes that slide with the two main guide rails 6 can be connected on both sides of the mounting frame 8; or roller structures that roll with the two main guide rails 6 can be connected on both sides of the mounting frame 8. The strong drive host 4 is connected to the mounting frame 8, and the front side of the mounting frame 8 is connected to an open manned platform. The mounting frame 8 here is essentially a backpack frame, and the open manned platform includes a bottom plate and a rear side plate. A support arm is connected to the bottom of the front side of the backpack frame, the bottom plate is installed on the support arm, and the rear side plate is connected to the backpack frame. In this type of open platform ladder structure, a top plate is usually connected to the front side of the backpack frame, and the top plate is located above the manned platform, which mainly plays a decorative effect. The user standing on the manned platform cannot see the top connection structure of the elevator.

[0035] In some other embodiments, a closed car structure may be directly connected to the supporting arm. Of course, the rear side of the car structure may be further connected and fixed to the backpack frame, and a car door may be provided on at least one side wall of the car.

[0036] In addition, the lower end of the fixing seat 7 is connected with a buffer member 9 which is opposite to the top of the mounting frame 8 and is used for anti-collision buffering.

[0037] In this embodiment, in order to ensure the safety of riding the elevator, especially the open platform elevator, the duplex elevator also includes a protection frame 10 surrounding the lifting unit and the guide rail unit. The outer wall of the protection frame 10 is connected to the middle building ring beam 2 through a connecting plate and expansion bolts. The bottom of the protection frame 10 may or may not be in contact with the bottom floor. See the attached Figure 2 However, the weight bearing point of the protection frame 10 is on the top ring beam 3 and / or the middle ring beam 2, ensuring that the bottom floor is not subjected to force or is subjected to very small force, ensuring that the installation of the protection frame 10 will not affect the load-bearing capacity of the bottom floor.

[0038] The side panels of the protection frame 10 are connected with sealing plates and floor doors. In order to reduce the load and facilitate transportation, the protection frame 10 here is preferably an aluminum alloy frame.

[0039] In some other embodiments, the outer wall of the protection frame 10 can be fixed to the top ring beam, or fixedly connected to the middle ring beam and the top ring beam at the same time.

[0040] More specifically, in order to further improve the stability of the connection structure of the protection frame 10, the rear side wall of the protection frame 10 is fixed to the middle building ring beam 2, and the left and right side walls and the front side wall of the protection frame 10 are fixedly connected to the middle building floor 11, see the attached Figure 3 .

[0041] In the description of the embodiments of the present application, it should be noted that in the description of the present application, terms such as "front" and "rear" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description, and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0042] In the description of the present application, the description with reference to the terms "present embodiment", "some embodiments", "specific examples", or "some examples" etc. means that the specific features, mechanisms, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradicting each other.

[0043] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
