Description
Technical Field
[0001] The utility model relates to the technical field of elevators, in particular to a traction wheel for elevator equipment. Background Art
[0002] Elevator equipment refers to mechanical equipment used for vertical or inclined transportation of people or objects. In buildings, elevator equipment is usually driven by an electric motor, and the elevator cabin is raised or lowered through a guide rail or a steel cable system, so that people can move quickly and safely between different floors inside the building. The traction wheel in the elevator equipment is an important component for lifting and lowering the elevator cabin. The traction wheel is usually installed on the top of the elevator shaft and driven to rotate by an electric motor to fix the wire rope or belt on the traction wheel, thereby realizing the operation of the elevator cabin. When the traction wheel is in use, the wire rope will constantly rub against the rope groove of the traction wheel. Over time, the traction wheel will be damaged and needs to be replaced. However, when replacing the existing traction wheel, the entire traction wheel is replaced. Replacing the entire traction wheel will lead to waste of materials in other parts, and only the traction wheel groove that is easily worn cannot be replaced. Therefore, those skilled in the art provide a traction wheel for elevator equipment to solve the problems raised in the above background technology. Utility Model Content
[0003] The purpose of the utility model is to provide a traction sheave for an elevator device to solve the problems raised in the above background technology.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A traction wheel for elevator equipment comprises a rotating rod, a mounting base is arranged at the rear end of the rotating rod, a traction wheel bracket is arranged on the rear side of the mounting base, limiting clamps are arranged at the front and rear ends of the outer side of the traction wheel bracket, a traction wheel groove is opened in the middle of two groups of limiting clamps, a rubber device is arranged at the inner end of the traction wheel groove, a first rope groove is arranged at the rear end of the rubber device, and a second rope groove is arranged at the front end of the rubber device.
[0006] Preferably, the lower inner ends of the first rope groove and the second rope groove and the inner end of the traction wheel bracket are provided with rubber device screw grooves, the inner ends of the rubber device screw grooves are provided with rubber device screws, the rear end of the mounting base is provided with a mounting protrusion, the middle of the mounting protrusion is provided with a docking groove, and fixing rods are provided at the four corners of the rear end of the mounting base.
[0007] Preferably, a mounting protrusion groove is provided at a position of the traction wheel bracket corresponding to the mounting protrusion, a fixing bolt groove is provided at a position of the traction wheel bracket corresponding to the fixing rod, a docking block is provided at a position in the middle of the traction wheel bracket corresponding to the docking groove, a picking block is fixedly connected to the front end of the docking block, a fixing bolt is provided at the inner end of the fixing rod, and a rotating hole is provided on the surface of the fixing bolt.
[0008] Compared with the prior art, the utility model has the following beneficial effects: when the traction wheel and the wire rope work for a long time, friction will cause damage, and the corresponding parts need to be replaced to make the traction wheel work normally and eliminate safety hazards. When the damage is caused by the friction of the rubber device inside the traction wheel, the rubber device can be replaced without replacing the traction wheel. The screws at the bottom of the first rope groove and the second rope groove of the rubber device are loosened by using a tool, and the rubber device can be taken out from the traction wheel groove and replaced with a new rubber device. Replacing the entire traction wheel is usually more expensive than replacing only parts. By replacing only the damaged rubber device, the maintenance cost can be saved and the service life of the entire traction wheel can be extended. At the same time, the rubber device can be replaced with a new one. For replacing the entire traction wheel, the maintenance process is simpler and faster, which can reduce maintenance time and improve maintenance efficiency. Replacing the entire traction wheel may require readjustment and calibration, while replacing only the rubber device can maintain the original performance and operating status of other parts, avoiding unnecessary adjustments. Replacing only damaged parts can reduce resource waste. When the entire traction wheel needs to be replaced, use a tool to rotate the rotating hole, loosen the fixing bolt from the fixing rod, and remove the traction wheel bracket by picking up the pick block. Install a new traction wheel bracket, align the mounting lug groove at the inner end of the new traction wheel bracket with the mounting lug on the mounting base for installation to achieve precise alignment and ensure that the traction wheel bracket can be correctly installed on the mounting base. This helps to avoid deviation or instability during the installation process, improve the accuracy and stability of the installation, and rotate and tighten the fixing bolt into the fixing rod to complete the installation.

[0015] The working principle of the utility model is that the traction wheel and the wire rope will cause friction and damage when working for a long time, and the corresponding parts need to be replaced to make the traction wheel work normally and eliminate safety hazards. When the rubber device inside the traction wheel is damaged by friction, the rubber device can be replaced without replacing the traction wheel. The screws at the bottom of the first rope groove and the second rope groove of the rubber device are loosened by using a tool, and the rubber device can be taken out from the traction wheel groove and replaced with a new rubber device. Replacing the entire traction wheel is usually more expensive than replacing only parts. By replacing only the damaged rubber device, the maintenance cost can be saved and the service life of the entire traction wheel can be extended. At the same time, replacing the rubber device is more costly than replacing the entire traction wheel. For a traction wheel, the maintenance process is simpler and faster, which can reduce maintenance time and improve maintenance efficiency. Replacing the entire traction wheel may require readjustment and calibration, while replacing only the rubber device can maintain the original performance and operating status of other parts, avoiding unnecessary adjustments. Replacing only damaged parts can reduce resource waste. When the entire traction wheel needs to be replaced, use a tool to rotate the rotating hole, loosen the fixing bolt from the fixing rod, and remove the traction wheel bracket by picking up the pick block. Install a new traction wheel bracket, align the mounting lug groove at the inner end of the new traction wheel bracket with the mounting lug on the mounting base for installation to achieve precise alignment and ensure that the traction wheel bracket can be correctly installed on the mounting base. This helps to avoid deviation or instability during the installation process, improve the accuracy and stability of the installation, and rotate and tighten the fixing bolt into the fixing rod to complete the installation.
