Description

Technical Field

[0001] This utility model relates to the field of platform elevator technology, and in particular to a platform elevator dual hidden point balance suspension device. Background Technology

[0002] As living standards improve, more and more villas are installing elevators, typically platform elevators.

[0003] The traction system is a crucial component of platform elevators, primarily used to move the car up or down. The traction system connects the car and counterweight via steel belts. Current conventional platform elevator traction systems typically use two steel belts connected to the rear of the car (similar to an L-shaped structure on a forklift). The platform car can deform under load, potentially causing abnormal noises during operation. Gaps may also appear at the joints due to car deformation, affecting the car's structural stability and aesthetics. Utility Model Content

[0004] The technical solution to be solved by this utility model is to provide a platform elevator with a double hidden point balance suspension device. By adding this double hidden point balance suspension device to the platform elevator, the car is subjected to more uniform force, which makes the platform elevator more stable and more aesthetically pleasing as a whole.

[0005] The technical solution adopted by this utility model is: a platform elevator double hidden point balance suspension device, including a traction main suspension, one end of which is connected to the rear of the car, and the other end of which is connected to the counterweight. It also includes a balance suspension, one end of which is connected to both sides of the front of the car, and the other end of which is connected to the counterweight.

[0006] Preferably, the car includes two front columns, and the balance suspension includes a first wire rope and a second wire rope, with one end of the first wire rope fixed to the top of one of the front columns and one end of the second wire rope fixed to the top of the other front column.

[0007] Preferably, the car includes a car floor and two front car pillars, and the balance suspension includes a first steel wire rope and a second steel wire rope. One end of the first steel wire rope passes through one of the front car pillars and is fixed to the car floor, and one end of the second steel wire rope passes through the other front car pillar and is fixed to the car floor.

[0008] Preferably, it also includes a hoistway, which includes two front hoistway columns and a hoistway top. A guide mechanism is provided on the hoistway top. The other ends of the first wire rope and the second wire rope are respectively connected to the counterweight through the guide mechanism. The portions of the first wire rope and the second wire rope located between the front hoistway columns and the hoistway top are in the rear obstruction area of ​​the front hoistway columns.

[0009] Preferably, the guiding mechanism includes two sets, left and right. Each set of guiding mechanisms includes a fixed plate fixed to the top of the hoistway and a first guide wheel and a second guide wheel fixed to the fixed plate for guiding the wire rope to the rear of the car. The first wire rope and the second wire rope are respectively connected to the front sides of the car through the first guide wheel, and the first wire rope and the second wire rope are respectively connected to the counterweight through the second guide wheel.

[0010] Preferably, the counterweight is provided with a balance rope head, and the other ends of the first wire rope and the second wire rope are both fixed to the balance rope head, and the tension of the first wire rope and the second wire rope can be adjusted through the balance rope head.

[0011] Preferably, the guiding mechanism further includes a third guide wheel and a fourth guide wheel for adjusting the direction of the first wire rope and the second wire rope.

[0012] Preferably, the fixing plates of the two sets of guide mechanisms are arranged in a cross configuration.

[0013] Compared with the existing technology, the present invention has the following advantages: by connecting the front two sides of the car with the counterweight through the balanced suspension, the car is subjected to force at three points, and the three force points are in a triangle, so the force is relatively uniform. This prevents the car from tilting during operation, thus making the entire elevator more reliable.

[0014] The first and second steel wire ropes are used as a balance suspension and are connected to the car floor. Because the car floor has high overall reliability, the car is subjected to more uniform stress.

[0015] The first and second wire ropes are passed through the front column of the car and connected to the car floor. This effectively conceals the first and second wire ropes, making them not only more aesthetically pleasing but also easier to install. Furthermore, the front column of the hoistway conceals the first and second wire ropes located between the top of the hoistway and the car, preventing them from being seen by external users, resulting in a more aesthetically pleasing overall appearance.

[0016] The first and second wire ropes are connected to the counterweight through a guiding mechanism, so that the first and second wire ropes will not come into contact with other structures, and the overall connection is relatively convenient.

[0017] By securing the wire rope with the balance rope end, not only is it firmly fixed, but the tension of the wire rope can also be adjusted.

[0018] The installation of a third and fourth guide wheel allows the first and second wire ropes to avoid obstructing structures and be easily connected to the counterweight. Attached Figure Description

Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] Example 1:

[0030] A platform elevator with dual hidden point balance suspension device, such as Figures 1-4As shown, it includes a traction machine 16, a traction main suspension 1, a balance suspension, a hoistway, a car 2, a guide mechanism, and a counterweight 3, wherein:

[0031] The hoistway includes a hoistway frame, a machine frame 17, and a hoistway top 9. The car 2 moves vertically within the hoistway frame. The hoistway frame includes hoistway columns and hoistway crossbars. The hoistway columns include two front hoistway columns 8. The machine frame 17 is fixed to the hoistway frame and is used to fix the traction machine 16. The hoistway is the same as that of the existing technology platform elevator, so it is not described in detail here.

[0032] The car 2 includes a car frame and two front columns 4 connected to the front of the car frame. The bottom of the car frame can also be called the car floor 7. The rear of the car frame is fixed with a traction rope head, which is used to fix the traction main suspension 1. The front columns 4 of the car are provided with through holes for cables to pass through, such as steel wire ropes. The structure of the car 2 is the same as that of the existing technology platform elevator, so it is not elaborated here.

[0033] The traction main suspension 1 consists of two steel belts. One end of each steel belt is fixed to the rear of the car 2, and the other end is fixed to the counterweight 3. The drive wheel of the traction machine 16 is passed through one of the belts, and the belts can be driven by the traction machine 16. The overall structure is the same as that of the existing technology platform elevator, so it is not described in detail here.

[0034] The balance suspension consists of two steel wire ropes, namely the first steel wire rope 5 and the second steel wire rope 6. One end of the first steel wire rope 5 passes through one of the front columns 4 of the car and is fixed to the front end of the car floor 7. The other end of the first steel wire rope 5 passes through the top of the hoistway 9 and is connected to the counterweight 3 through a guide mechanism. The second steel wire rope 6 is the same. One end passes through the other front column 4 of the car and is fixed to the other end of the front end of the car floor 7. The other end of the second steel wire rope 6 passes through the top of the hoistway 9 and is connected to the counterweight 3 through a guide mechanism. After the first steel wire rope 5 and the second steel wire rope 6 pass out of the front column 4 of the car, they are blocked by the front column 8 of the hoistway. Because the cross-section of the front column 8 of the hoistway is C-shaped, the first steel wire rope 5 and the second steel wire rope 6 are within the C-shaped blocking area of ​​the front column 8 of the hoistway. That is, at this time, it is not easy for the user to see the first steel wire rope 5 and the second steel wire rope 6 from outside the elevator.

[0035] Counterweight 3 is equipped with a traction rope head for fixing the other end of the two steel belts. Balance rope heads 13 are provided on both sides of the traction rope head. These two balance rope heads 13 are used to fix the other end of the first steel wire rope 5 and the second steel wire rope 6. Both the traction rope head and the balance rope head 13 have the function of adjusting the tension.

[0036] The guiding mechanism includes a fixed plate 12, a first guide wheel 10, a second guide wheel 11, a third guide wheel 14, and a fourth guide wheel 15, wherein:

[0037] There are two fixing plates 12, which are fixed on both sides of the top 9 of the shaft respectively;

[0038] The first guide wheel 10 is fixed on one side of the fixed plate 12, and the second guide wheel 11 is fixed on the other side of the fixed plate 12. Both are fixed pulleys. The purpose of the first guide wheel 10 and the second guide wheel 11 is to guide the first wire rope 5 and the second wire rope 6 to the rear of the car 2.

[0039] The third guide wheel 14 and the fourth guide wheel 15 are fixed at the lower end of the frame 17. They are also fixed pulleys. Their purpose is to adjust the direction of the first wire rope 5 and the second wire rope 6 so that the first wire rope 5 and the second wire rope 6 can avoid some structures, such as the traction machine 16 and its guide rail assembly. In this way, the first wire rope 5 and the second wire rope 6 can be directly connected to the counterweight 3 after being guided by the third guide wheel 14 and the fourth guide wheel 15.

[0040] The working principle of this embodiment is that when the elevator is working, the first steel wire rope 5 and the second steel wire rope 6 will connect the counterweight 3 and the front two sides of the car floor 7, and the steel belt will connect the middle of the rear of the car 2 and the counterweight 3. This is equivalent to the car 2 being subjected to force at three points, and the three points are distributed in a triangle, so that the car 2 is subjected to uniform force as a whole. The car 2 will not tilt during the operation of the elevator, and the car is balanced by the weight of the counterweight through the tension of the steel wire rope.

[0041] Example 2:

[0042] like Figure 5-6 As shown, the difference from Embodiment 1 is that the guiding mechanism in Embodiment 2 only includes a fixed plate 12, a first guide wheel 10 and a second guide wheel 11. That is, the first wire rope 5 and the second wire rope 6 are directly connected to the counterweight 3 after being guided by the first guide wheel 10 and the second guide wheel 11. This embodiment is applicable to situations where the first wire rope 5 and the second wire rope 6 are not blocked by other components after being guided by the first guide wheel 10 and the second guide wheel 11.

[0043] Example 3:

[0044] like Figure 7-8 As shown, the difference from Embodiment 1 is that the fixing form of the fixing plate 12 in the guide mechanism of Embodiment 3 is different. In Embodiment 3, the fixing plates 12 are arranged in a cross pattern but do not overlap. This is equivalent to the first steel wire rope 5 on the left side of Embodiment 1 being connected to the balance rope head 13 on the left side of the counterweight 3, and the second steel wire rope 6 on the right side being connected to the balance rope head 13 on the right side of the counterweight 3; while in Embodiment 3, the first steel wire rope 5 on the left side is connected to the balance rope head 13 on the right side of the counterweight 3, and the second steel wire rope 6 on the right side is connected to the balance rope head 13 on the left side of the counterweight 3.

[0045] Example 4:

[0046] The difference from Embodiment 1 is that in Embodiment 4, the first wire rope 5 and the second wire rope 6 do not pass through the front column 4 of the car, but are fixed to the top of the car at the upper end of the front column 4 of the car. This is equivalent to the point of force being the top of the car rather than the bottom plate 7 of the car, but the triangular force formed by the three points of force is still the same.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.

[0048] For those skilled in the art, various changes and modifications will undoubtedly be apparent after reading the above description. Therefore, the appended claims should be considered as covering all changes and modifications that encompass the true intent and scope of this utility model. Any and all equivalent scope and content within the scope of the claims should be considered as still falling within the intent and scope of this utility model.
