Device and method for lifting spare tire by telescopic oil cylinder

Abstract

The invention discloses a device and method for lifting a spare tire by a telescopic oil cylinder. The device comprises a lifting rope and a supporting and lifting assembly; the lifting rope is made of steel wires; one end of the supporting and lifting assembly is detachably fixed to a telescopic operation arm of a vehicle, and the other end of the supporting and lifting assembly is suspended above the spare tire; and one end of the lifting rope is fixed to a telescopic section of the telescopic oil cylinder for driving the telescopic operation arm to stretch, the end part of the lifting rope is mounted on the supporting and lifting component in a movable displacement manner to be hung, and the hung lifting rope is wound, bound and fixed to the spare tire during use. Due to the fact that the telescopic operation arm is carried by the vehicle, the lifting rope can be driven by the telescopic operation arm to move and displace on the supporting and lifting assembly, the spare tire can be lifted, a motor does not need to be additionally installed to take up and pay off the lifting rope, and lifting can be achieved; and the problems that in the prior art, motor power needs to be increased, loads are increased, and maximum effective utilization of the space structure of the operation vehicle is affected are solved.

Description

technical field [0001] The invention relates to a device and method for hoisting a spare tire with a telescopic oil cylinder, belonging to the technical field of hoisting. Background technique [0002] For vehicles, rolling tires are one of the most important moving parts. Vehicles need to carry spare tires. For heavy-duty work vehicles, sometimes for better layout to maximize the use of space structures of work vehicles, The spare tire 53 will be suspended and installed on the vehicle frame 52 below the telescopic operation arm 54 on the right side of the vehicle 51, the suspension installation point is about 900 mm above the ground, and the weight of the spare tire is about 110 kilograms, such as figure 1 mentioned. When replacing and installing the spare tire, due to the limited location of the spare tire, the space is inconvenient for many people to use it. Within the scope of limited manpower, it is difficult to lift the spare tire with a weight of 110 kg to the instal...

Problems solved by technology

When replacing and installing the spare tire, due to the limited location of the spare tire, the space is inconvenient for many people to use it. Within the scope of limited manpower, it is difficult to lift the spare tire with a weight of 110 kg to the installation position, and it is difficult to accurately align and install it. holes and tighten the spare wheel bolts to secure

[0003] In the Chinese patent publication number CN204355178U discloses a kind of ambulance spare tire overhead mechanism, although the disclosed motor and suspension wire can lift the ambulance spare tire, the ambulance spare tire is generally a car tire with a weight of 25-40 kg ; while the weight of the spare tire of a heavy-duty work vehicle is about 110 kg, the power of the motor used needs to be increased, and the increase in the power of the motor will lead to an increase in the coil winding of the motor, so the size and weight of the motor will inevitably increase, which increases for heavy-duty work vehicles. At the same time, because the large-sized motor needs to accommodate the large-sized motor space, it affects the maximum and effective use of the space structure of the working vehicle. In order to meet the electric energy of the increased power motor, it is necessary to install a power converter on the heavy-duty working vehicle, resulting in a further increase. Load and influence vehicle space structure
