Description

Technical Field

[0001] This utility model relates to the field of elevator technology, and in particular to an elevator structure. Background Technology

[0002] The rope winding structure of an elevator car can be divided into top lifting, bottom lifting, and middle lifting according to the location of the force. That is, the steel wire rope lifts the upper beam at the top of the car to provide power for the car to move up and down, and lifts the car at the bottom. There is also a backpack structure in which the steel wire rope lifts the middle of the back beam. Each of these three lifting methods has its advantages and disadvantages. The top-lifting method has a good arrangement of lifting points, balanced force distribution, and good running comfort, but it requires a large car top space, which cannot be met when the top height is small. The bottom-lifting method has the same advantages as the top-lifting method, with a reasonable distribution of lifting points and good car comfort. The disadvantage is that it requires a large pit space, which cannot be met when the pit depth is small. The third method is the backpack structure, with the force point in the middle of the upright beam. This method does not require a large pit depth or top height, but the force structure is poor. Due to structural limitations, the force point of the two steel wire ropes is only one side of the car, and the stress is concentrated on the bottom of the car and the upright beam. The connection between the upright beam and the bottom of the car is subjected to greater force, and the guide shoe is subjected to greater force on one side, resulting in poor running comfort.

[0003] With limited top floor height and pit depth, most solutions cannot meet comfort requirements during operation. Therefore, there is an urgent need for an elevator structure that, within the limited space of the top floor and pit, can ensure both safe vertical operation and comfortable ride.

[0031] like Figures 1 to 4 As shown, this utility model embodiment provides an elevator structure, including a hoist frame 100 installed in the elevator shaft. Each floor of the hoist frame 100 is equipped with an elevator door 110. The elevator door 110 is variably designed according to the layout of users or floors. In this embodiment, the doors of the upper and lower floors are designed as adjacent structures. The hoist frame 100 is provided with two sets of guide rails 200, which are located on the side closest to the shaft. A car 300 is slidably mounted on the guide rails 200. The car 300 slides on the guide rails 200 via guide shoes 210. The sliding connection between the guide shoes 210, the car 300, and the guide rails 200 is... This is existing technology and not an innovation of this utility model, so it will not be elaborated here; A drive mechanism 600 is provided on the bottom side of the derrick 100 near the guide rail 200. The output end of the drive mechanism 600 is provided with a first lifting rope 640 and a second lifting rope 650.

[0032] This utility model embodiment provides an elevator structure. The drive mechanism 600 is located at the bottom of the hoist 100, and a first guide component 400 and a second guide component 500 are arranged at the top of the hoist 100. The arrangement of the first guide component 400 and the second guide component 500 allows the first lifting rope 640 and the second lifting rope 650 to require only a small amount of top space when passing around the first guide component 400 and the second guide component 500. At the same time, the first lifting rope 640 and the second lifting rope 650 are guided by the first guide component 400 and the second guide component 500 so that the first lifting rope 640 and the second lifting rope 650 are respectively connected to opposite corners of the car 300, ensuring that the center of gravity of the car 300 is basically consistent with the center position, and the stability and comfort of the car 300 during up and down operation are better.

[0033] In some embodiments, such as Figure 1 , 3As shown in Figure 4, the drive mechanism 600 includes a drive motor 610. The output end of the drive motor 610 is provided with a first winding drum 620 and a second winding drum 630. One end of the first lifting rope 640 is connected to the first winding drum 620, and one end of the second lifting rope 650 is connected to the second winding drum 630. Specifically, in this embodiment, the drive motor 610 drives the first winding drum 620 and the second winding drum 630 to rotate forward or in reverse, enabling the car 300 to move smoothly up and down.

The first angle 301 and the third angle 303 are diagonal, and the second angle 302 and the fourth angle 304 are diagonal. The first lifting rope 640 sequentially passes around the first guide wheel 410, the second guide wheel 420, the third guide wheel 430, and the fourth guide wheel 440. The first guide wheel 410 is located above the first angle 301 of the car 300, the fourth guide wheel 440 is located above the first winding drum 620, and the second guide wheel 420 is located above the second angle 302. Specifically, the first lifting rope 640 starts from one side of the first angle 301 and first passes around the first guide wheel 410 from bottom to top. The first guide wheel 410 and the second guide wheel 420 are on the same horizontal line. The first guide wheel 410 and the second guide wheel 420 are rotatably connected to the first mounting bracket 120. The first lifting rope 640 then passes over the second guide wheel 420 from top to bottom. The second guide wheel 420 guides the lifting rope to the side close to the drive motor 610. The first lifting rope 640 then passes over the third guide wheel 430 from bottom to top. The third guide wheel 430 and the fourth guide wheel 440 are both rotatably mounted on the second mounting bracket 130. The third guide wheel 430 changes the direction of the first lifting rope 640. The first lifting rope 640 then passes over the fourth guide wheel 440 from top to bottom. The fourth guide wheel 440 guides the first lifting rope 640 to the drive motor 610, so that one end of the first lifting rope 640 is connected to the first winding drum 620. When the drive motor 610 drives the first winding drum 620 to rotate forward or reverse, it winds or unwinds the first lifting rope 640, enabling the car 300 to move up and down.

Specifically, the fifth guide wheel 510, the sixth guide wheel 520, the seventh guide wheel 530, and the eighth guide wheel 540 are all rotatably mounted on the second mounting bracket 130. The second lifting rope 650, starting from the third corner 303, first passes over the fifth guide wheel 510 from bottom to top, then passes over the sixth guide wheel 520 from top to bottom. The sixth guide wheel 520 guides the first lifting rope 640 closer to the drive mechanism 600. The second lifting rope 650 then passes over the seventh guide wheel 530 from bottom to top, which acts as a reversing wheel. The second lifting rope 650 then passes over the eighth guide wheel 540 from top to bottom, which guides the second lifting rope 650 to the drive mechanism 600. When the drive motor 610 drives the second winding drum 630 to rotate forward or reverse, it winds or unwinds the second lifting rope 650, allowing the car 300 to move up and down.

[0036] In some embodiments, such as Figures 1 to 4 As shown, the car 300 includes a car top 310, a car bottom 320, and car walls 340. The car bottom 320 and its four corners are connected by vertical beams 330. Specifically, lifting rods 350 can be installed at the four corners of the car 300, and the car top 310, car bottom 320, and vertical beams 330 can be locked together by using nuts and threads. The car walls 340 are designed according to the opening direction of the elevator door 110. In this embodiment, only the vertical surfaces at the positions between the first corner 301 and the second corner 302, and the third corner 303 and the second corner 302 have car walls 340. Furthermore, the upright beam 330 is provided with a first vertical beam 331 at the first corner 301, and a first rope end fixing seat 3311 is provided on the first vertical beam 331.
