TECHNICAL FIELD

[0001] The utility model belongs to elevator technical field, concretely relates to an elevator with high-speed stable running. BACKGROUND

[0002] The elevator is a vertical lift with motor power, which is equipped with a box-shaped cabin and can be used for carrying people or goods in multi-storey buildings. With the rapid development of industry, freight elevators have been widely used, for example, freight elevators have been widely used in factories, warehouses, shopping centers, hotels, airports, stations and other places.

[0003] However, the existing high-speed elevator is also applied to high-rise buildings. When the high-speed elevator runs, its running speed is high, and it usually uses a single counterweight frame, which cannot stably pull the elevator, so the vibration of the elevator increases with the increase of speed, which becomes an important factor affecting the comfort of elevator riding. INVENTION CONTENTS

[0004] In view of the shortcomings of the prior art, the utility model solves the technical problem of providing an elevator with high-speed stable running, which can stably pull the elevator and make the elevator run smoothly.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of an elevator with high-speed stable running, which comprises a car, a car frame and three counterweight frames. The car is slidingly installed in the car frame, and the three counterweight frames are slidingly installed outside the car frame. The three counterweight frames correspond to the three sides of the car respectively, and the three counterweight frames are connected to the top of the car through traction ropes respectively.

[0006] The car frame is provided with a guide rail, and the car is provided with a guide assembly matched with the guide rail.

[0007] The guide assembly comprises two guide wheels, and the rotating surfaces of the two guide wheels are respectively arranged on the corresponding two sides of the guide rail.

[0008] The guide rail is provided with a plurality of transmission wheels at one end of the side wall of the car, and the plurality of transmission wheels are arranged on the side wall of the car.

[0009] The bottoms of the three counterweight frames are connected to the bottom of the car through traction ropes respectively.

[0010] The car frame is provided with a guide groove corresponding to the surface of the counterweight frame, and the counterweight frame is provided with a sliding wheel slidingly arranged in the guide groove.

[0011] The elevator further comprises a traction motor located at the top of the elevator shaft for driving the traction rope to traction.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model discloses an elevator with high -speed stable travel, through three counterweight frames respectively to the three directions of car are hauled and form three traction force points, thereby multiple force points compare the single more stable of traction force point, realize stable pulling elevator, make elevator smooth operation.

[0017] In order to let the above-mentioned features and advantages of the utility model more obvious and easy to understand, the following specific examples, and cooperate with the drawings, make detailed description as follows.

[0018] As Figure 1 And Figure 2 The utility model discloses an elevator with high -speed stable travel, including car 1, car frame 2 and three counterweight frames 3, car 1 sliding installation is in car frame 2, three counterweight frames 3 sliding installation is in car frame 2, and three counterweight frames 3 correspond car 1 three face sides respectively, and three counterweight frames 3 are connected with the top of car 1 through traction rope 4 respectively. Specifically, the bottom of three counterweight frames 3 is connected with the bottom of car 1 through traction rope 4 respectively. Through three counterweight frames 3 respectively to the three directions of car 1 are hauled and form three traction force points, thereby multiple force points compare the single more stable of traction force point, realize stable pulling elevator, make elevator smooth operation.

[0019] Further, car frame 2 is equipped with guide rail 5, and car 1 is equipped with a guide assembly matched with guide rail 5. Specifically, the guide assembly includes two guide wheels 6, and the rotating surfaces of the two guide wheels 6 are respectively arranged on the corresponding two sides of guide rail 5. The two guide wheels 6 clamp guide rail 5, so that car 1 moves stably along car frame 2.

[0020] Further, a plurality of transmission wheels 7 are installed at one end of guide rail 5 facing the side wall of car 1, and the plurality of transmission wheels 7 are arranged on the side wall of car 1. The plurality of transmission wheels 7 are arranged to prevent the side wall of car 1 from directly rubbing against guide rail 5, thereby preventing damage.

[0021] Further, the car frame 2 is provided with a guide groove corresponding to the surface of the counterweight frame 3, and the counterweight frame 3 is provided with a sliding wheel 8 which is slidably arranged in the guide groove. The sliding wheel 8 is arranged to stabilize the movement of the counterweight frame 3.

[0022] Further, the elevator further comprises a traction motor arranged in the top of the elevator shaft for driving the traction rope 4 to perform traction, and the traction motor is not marked in the figure. The traction motor drives the traction rope 4 to make the car 1 move up and down.

[0023] The basic principle and main features of the present application and the advantages of the present application are shown and described above, and those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only to illustrate the principle of the present application.
