Description

Technical Field

[0001] The utility model belongs to the technical field related to traction elevator structures, and particularly relates to a traction elevator structure. Background Art

[0002] A traction elevator is a mechanical device that uses steel wire ropes or steel-cored belts to achieve vertical movement. The structure of a traction elevator primarily consists of the following components: the traction system, which is the heart of the elevator and consists of the traction machine, traction wire ropes, and guide pulleys. The traction machine, installed in the machine room, typically consists of an electric motor, a reduction gearbox, and a brake, providing power. The traction wire ropes are connected to the car at one end and the counterweight at the other. The friction between the traction sheave and the traction ropes propels the car and counterweight in relative motion, achieving the elevator's vertical transport function. The guide system, which restricts the movement of the car and counterweight to the guide rails, primarily consists of the car guide rails, counterweight guide rails, guide shoes (guide pulleys), and guide rail brackets. The car system, which is the elevator component used to transport passengers or cargo, consists of the car frame and car body. The car frame is the load-bearing component of the car body, and the car body is fixed to the car frame. It includes the inner wall, outer wall, car roof, and car decorative parts. The door system, including the car door and hall door, is responsible for the entry and exit of passengers and cargo. The car door system consists of the car door machine and car door panel, while the hall door system includes the hall door hanging plate and hall door panel. When a traction elevator opens to allow passengers to enter, a leakage channel is formed at the lower end of the elevator door. The user's belongings can easily fall into the corridor and be damaged on the ground floor. The present utility model improves on this problem and specifically relates to a traction elevator structure that is safe and prevents items from falling. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-3As shown, a traction elevator structure includes a traction elevator car 4 and a car door 5 arranged at the middle position of the front end of the traction elevator car 4; a car base 10 is arranged at the bottom position of the traction elevator car 4, a telescopic connecting plate 11 is arranged at the middle position of the car base 10, a second telescopic inflatable body 15 is arranged at the inner position of the telescopic connecting plate 11, a connecting conduit 14 is arranged at the inner position of the second telescopic inflatable body 15, a first telescopic inflatable body 13 is arranged at the inner position of the connecting conduit 14, and a connecting movable bar 12 is connected to the end position of the first telescopic inflatable body 13. The other end of 12 is connected to the bottom of the car elevator door 5 near the middle position. When the car elevator door 5 is opened, the first telescopic inflatable gas 13 is compressed, the second telescopic inflatable gas 15 is extended, and the telescopic connecting plate 11 is extended from the car base 10. The extended telescopic connecting plate 11 can block the leakage path and prevent objects from falling from the leakage path. When the elevator door is closed, the first telescopic inflatable gas 13 is extended, the second telescopic inflatable gas 15 is contracted, and the telescopic connecting plate 11 is retracted into the car base 10. Through the improvement of the utility model, effective protection can be provided when the elevator door is opened, thereby effectively improving the practicality of the traction elevator structure.

[0021] like Figure 1 As shown, traction elevator car 4 is provided with side guide rails 8 on both sides. These side guide rails 8 are connected to the wall via screws. They serve as safety rails for the elevator as it travels up and down the hoistway. The guide rails are mounted on the hoistway wall and secured to the hoistway wall by guide rail brackets and guide rail supports. Elevator guide rails provide guidance for the car and counterweight during operation and also provide support during safety clamp braking. They are crucial components in the elevator system.

[0022] like Figure 1 As shown, a car door machine 6 is installed near the upper end of the traction elevator car 4. This mechanism is responsible for opening and closing the elevator hall door. When it receives the elevator door opening or closing signal, the door machine controls the door opening motor through its own control system, converting the torque generated by the motor into a force in a specific direction to close or open the door. When the force preventing the door from closing exceeds 150N, the door machine automatically stops closing the door and opens it in the opposite direction, providing a certain degree of door closing protection.

[0023] like Figure 1 As shown, an elevator buffer 7 is provided at the middle position of the upper end of the traction elevator car 4. The bottom of the elevator buffer 7 is mounted on the traction elevator car 4 by screws, and a connecting spring is provided in the middle. The main function of the elevator buffer 7 is to absorb the kinetic energy of the elevator during the operation of the elevator, especially when the elevator loses control or stops in an emergency, to reduce the impact force of the elevator on passengers and equipment, thereby protecting the safety of passengers and equipment.

[0024] like Figure 1As shown, connecting drive wire ropes 3 are provided at both sides of the elevator buffer 7, and a lifting limiter and an anti-broken rope protection device are provided at the connection position of the connecting drive wire rope 3 and the traction elevator car 4. A traction elevator driving motor 1 is provided at the end position of the connecting drive wire rope 3, and the traction elevator driving motor 1 is electrically connected to the external motor. A driving connecting drum 2 is provided near the two ends of the traction elevator driving motor 1, and the driving connecting drum 2 is connected to the connecting drive wire rope 3. An upper connecting support frame 9 is provided at the bottom position of the traction elevator driving motor 1, and the traction elevator driving motor 1 and the upper connecting support frame 9 are connected by screws. The upper connecting support frame 9 is installed and connected to the walls at both ends by screws. One end of the connecting drive wire rope 3 tractions the elevator car 4, and the other end is connected to the counterweight device. Through the friction between the driving connecting drum 2 and the connecting drive wire rope 3, the traction elevator car 4 and the counterweight move relative to each other, thereby realizing the vertical transportation function of the elevator.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
