Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a car mechanism and a traction elevator. Background Art

[0002] An elevator traction machine is the power equipment of an elevator, also known as the elevator main engine. Its function is to transmit and deliver power to make the elevator run. It consists of a car, a motor, a brake, a coupling, a speed reducer, a traction wheel, a frame, a guide wheel, an attached handwheel for turning the car by hand, etc.

[0003] The car is one of the main components of the elevator. A car top wheel is usually arranged on the top of the car. The motor makes the car move up and down by winding and unwinding the steel wire rope. Some car top wheels are arranged on the car upper beam. This design will generate large vibrations during the elevator's lifting and lowering, resulting in poor comfort. In addition, when installing some car top wheels, the angle adjustment is inconvenient and not easy to install.

[0004] For example, Chinese Patent Application No.: CN201420636226.6, a car top wheel assembly for an elevator, includes a car top wheel, an upper fixing plate, a lower fixing plate, a fixing bolt and a locking nut; the axis of the car top wheel is horizontally placed, the car top wheel is provided with a wheel shaft whose axis is consistent with its axis, and the car top wheel can rotate based on the wheel shaft; both ends of the wheel shaft are installed with wheel shaft fixing plates for fixing the wheel shaft, and an upper fixing plate fixed to the wheel shaft fixing plate is arranged below the car top wheel; the stud head of the fixing bolt passes through the upper fixing plate, the car upper beam, the lower fixing plate in sequence from above the upper fixing plate, and then is screwed to the locking nut; the lower fixing plate includes a first lower fixing plate, a damping pad and a second lower fixing plate stacked in sequence. The car top wheel is directly arranged on the car upper beam. This design will generate large vibrations during the elevator's lifting and lowering, resulting in poor comfort. At the same time, when installing this kind of car top wheel, the angle adjustment is inconvenient and not easy to install.

[0005] Another example: Chinese Patent Application No.: CN201220103279.2, an elevator car top wheel device. Although it uses shock-absorbing rubber for shock absorption, it also has the problem that the angle of the car top wheel cannot be adjusted during installation, making it not easy to install.

[0033] The present application provides a car mechanism, including a car 10 and a car top wheel device 20; the car 10 is provided with a car door 110, and a safety edge device 19 is arranged on the car door 110; a guardrail 11 and a lubrication device 30 are arranged on the top of the car 10; the car top wheel device 20 is arranged on the top of the car 10 and is located within the guardrail 11; the car top wheel device 20 includes a rope wheel 21, a rope wheel bracket 210, a connecting plate 211, a spring 212, and a spring seat 213; the spring 212 is arranged on the spring seat 213 and is connected to the connecting plate 211; a first connecting member 214 is rotatably passed through the rope wheel bracket 210, the spring seat 213, and the connecting plate 211; a first locking member 215 is fastened to the lower end of the first connecting member 214; a first pin shaft 216 is passed through the first locking member 215 and the first connecting member 214. The car door 110 is arranged on the slide rail of the car 10. The car door 110 on the car 10 can be opened or closed in a bi-parting or single-opening form. In this embodiment, the car door 110 can be driven by a motor to drive a gear and rack to open or close the car door 110, or the car door 110 can be opened or closed by the motor pulling a steel wire. More preferably, a distance sensor 23 is arranged on the top of the car 10 to detect the position of the car 10. The distance sensor 23 is connected to the elevator control system to facilitate real-time monitoring of the elevator. The height of the guardrail 11 is not higher than 1.2 m, and a protection door is arranged on the guardrail 11. The guardrail 11 improves the safety of maintenance personnel and also prevents objects from falling during maintenance.
