Description

Technical Field

[0001] The present application belongs to the technical field of crane wheels, and specifically relates to a crane wheel. Background Art

[0002] A crane wheel generally refers to a wheel used for lifting machinery or hoisting equipment. It is a wheel specially designed for lifting machinery or hoisting equipment, with the characteristics of strong load-bearing capacity, wear resistance, durability, and precision manufacturing to ensure that the lifting machinery can operate stably and efficiently.

[0003] For example, publication number: CN203529736U discloses a crane wheel, including a wheel body, a rim is formed on the left end periphery of the wheel body, a gear is formed on the right end periphery, and an axle hole is opened on the wheel body. The utility model improves the wheel shape, changes the structure in which the rim and the gear are formed on the right end periphery of the original crane wheel, makes it difficult for the wheel to deflect horizontally and cause rail gnawing, and reduces the thickness of the wheel, saves materials, and has a simple structure.

[0004] However, the crane wheels in the application lack sufficient lubrication, which will increase the friction between the axle and the bearing, thus accelerating the wear and damage of the parts. This may lead to early failure of the bearing, deformation or cracks of the axle, thus affecting the safety and reliability of the crane. Utility Model Content

[0005] The purpose of the present application is to provide a crane wheel in order to solve the above-mentioned problem of lack of sufficient lubrication of the crane wheel.

[0006] The technical solution adopted in the present application is as follows: a crane wheel comprises a wheel hub, a lubricating oil tank is fixedly connected to one side of the wheel hub, a lubricating oil pipe is fixedly connected to one end of the lubricating oil tank, a lubricating oil pipe cover is provided at one end of the lubricating oil pipe opposite to the lubricating oil tank, a small lubricating oil pump is provided at one end of the lubricating oil tank opposite to the lubricating oil pipe, and a lubricating oil nozzle is provided at one end of the small lubricating oil pump opposite to the lubricating oil tank.

[0007] By adopting the above technical solution, a wheel axle lubrication structure is added to a crane wheel, wherein the lubricating oil pipeline cover can be opened to pour the lubricating oil into the lubricating oil tank along the lubricating oil pipeline, and then the lubricating oil is sent to the lubricating oil nozzle through a small lubricating oil pump, and then the lubricating oil is sprayed by the lubricating oil nozzle. The wheel axle lubrication system can provide sufficient lubricating oil to key parts such as the wheel axle and bearing in time, reduce the friction between metal surfaces, thereby reducing wear and damage, and extending the service life of parts. Fully lubricated wheel axles and bearings can reduce the friction resistance of the mechanical system, reduce energy loss, and improve energy utilization, thereby reducing the energy consumption cost of the crane. A good lubrication state can maintain the normal operation of the wheel axle and bearing, reduce failures and downtime caused by friction and wear, and improve the operation efficiency and reliability of the crane. An appropriate wheel axle lubrication system can reduce wear and damage of mechanical parts, reduce maintenance and replacement costs, extend maintenance cycles, reduce downtime, and improve the maintainability and economy of the crane. Lubricating oil can reduce friction and heat between mechanical parts, reduce accidents caused by overheating or damage, and improve the operation safety of the crane. In harsh working environments, such as high temperature, high humidity, high dust, etc., the axle lubrication system can maintain the lubrication effect, extend the service life of mechanical parts, and improve the adaptability and stability of the crane. Therefore, adding an axle lubrication structure can effectively improve the performance, reliability and safety of the crane wheel, and provide guarantee for its long-term stable operation.

[0008] In a preferred embodiment, a plurality of spokes are fixedly connected to the outer surface of the hub, and a rim is fixedly connected to one end of the spokes relative to the hub.

[0009] By adopting the above technical solution, the spokes are the structural components of the wheel, located in the center of the rim, connecting the rim and the axle. They provide a bracket to support and connect the other parts of the wheel. The rim is the outer annular part of the wheel, and the tire is mounted on its outside. The rim supports and fixes the tire, allowing the wheel to contact the ground and transfer the weight and power of the vehicle.

[0010] In a preferred embodiment, a tire is provided on the outer surface of the rim.

[0011] By adopting the above technical solution, the tire is the outer rubber part of the wheel, which directly contacts the ground. The tire provides friction between the vehicle and the ground, enabling the vehicle to travel, turn and brake.

[0012] In a preferred embodiment, a wheel axle is disposed on one side surface of the wheel hub, and a brake disc is disposed on one end of the wheel axle opposite to the wheel hub.

[0013] By adopting the above technical solution, the axle is the key component connecting the wheels and is responsible for transmitting the weight and power of the vehicle. The axle is made of strong metal materials to withstand various stresses and loads when the vehicle is running. The brake disc is part of the braking system and is installed on the axle. When the caliper applies braking force, the brake disc rotates and contacts the caliper, thereby slowing down or stopping the rotation of the wheel.

[0014] In a preferred embodiment, a caliper is provided on the outer surface of the brake disc.

[0015] By adopting the above technical solution, the caliper is one of the key components of the braking system, which is used to apply braking force to slow down or stop the rotation of the wheel. The caliper is installed on both sides of the brake disc. When the brake is activated, the caliper clamps the brake disc to produce a braking effect.

[0016] In a preferred embodiment, a piston cylinder is provided on one side of the caliper, and a pressure transmission pipe is fixedly connected to one end of the piston cylinder relative to the caliper.

[0017] By adopting the above technical solution, the piston cylinder is one of the core components of the hydraulic brake system. It contains a piston. When the brake system receives an activation signal, the hydraulic pressure pushes the piston and applies pressure to the brake disc, thereby braking the wheel. The pressure transmission pipe is a pipe connecting the anti-lock brake system and the piston cylinder. It is responsible for transmitting the hydraulic pressure generated by the anti-lock brake system and applying it to the piston cylinder, thereby activating the brake system.

[0018] In a preferred embodiment, one end of the pressure transmission pipe relative to the piston cylinder is fixedly connected to an anti-lock braking system, and a vacuum booster is provided at the upper end of the anti-lock braking system.

[0019] By adopting the above technical solutions, the anti-lock braking system is a vehicle safety system that can prevent wheel locking and loss of directional control when braking. It senses the wheel speed and adjusts the brake pressure to ensure that the wheels keep spinning and the vehicle remains stable. The vacuum booster is an auxiliary braking system that uses the vacuum negative pressure of the engine to enhance the driver's braking force on the brake pedal. It helps the driver to apply sufficient braking force more easily, improving the efficiency and responsiveness of the braking system.

[0020] In a preferred embodiment, a connecting plate is provided on one side of the vacuum booster, and a brake pedal is provided at the lower end of the connecting plate.

[0021] By adopting the above technical solution, the connecting plate connects the vacuum booster and the brake pedal, which ensures the stability and unity of the overall structure and is one of the important components of the overall structure. The driver can activate the brake system by stepping on the brake pedal to slow down or stop the movement of the vehicle. Releasing the brake pedal will release the brake system and the vehicle can continue to move.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In the present application, a wheel axle lubrication structure is added to a crane wheel, wherein the lubricating oil pipeline cover can be opened to pour the lubricating oil into the lubricating oil tank along the lubricating oil pipeline, and then the lubricating oil is sent to the lubricating oil nozzle via a small lubricating oil pump, and then the lubricating oil is sprayed by the lubricating oil nozzle. The wheel axle lubrication system can provide sufficient lubricating oil to key parts such as the wheel axle and bearing in time, reduce the friction between metal surfaces, thereby reducing wear and damage, and extending the service life of parts. Fully lubricated wheel axles and bearings can reduce the friction resistance of the mechanical system, reduce energy loss, and improve energy utilization, thereby reducing the energy consumption cost of the crane. A good lubrication state can maintain the normal operation of the wheel axle and bearing, reduce failures and downtime caused by friction and wear, and improve the operation efficiency and reliability of the crane. An appropriate wheel axle lubrication system can reduce wear and damage of mechanical parts, reduce maintenance and replacement costs, extend maintenance cycles, reduce downtime, and improve the maintainability and economy of the crane. Lubricating oil can reduce friction and heat between mechanical parts, reduce accidents caused by overheating or damage, and improve the operation safety of the crane. In harsh working environments, such as high temperature, high humidity, high dust, etc., the axle lubrication system can maintain the lubrication effect, extend the service life of mechanical parts, and improve the adaptability and stability of the crane.
