Truck tire replacement auxiliary carrying device

Abstract

The invention discloses a truck tire replacement auxiliary carrying device which can be fixedly installed on the side face of a truck compartment, a fixed stand column serves as a rack and can be connected with a bearing basket for containing tires through pulleys on the side wall, and the two ends of the fixed stand column are connected with two foldable stand columns through rotating pairs. One fixed pulley of the upper stand column is in transmission with the fixed pulley of the fixed stand column through a belt, and the fixed pulley is connected with the fixed pulley in the other set of the same device, so that the purpose of lifting the damaged tire by utilizing the gravity of the spare tire when the spare tire on the left side descends is achieved.

Description

Technical Field

[0001] The present invention relates to the field of an auxiliary handling device for replacing truck tires. Background Art

[0002] During the process of replacing a truck tire, it is necessary to remove the spare tire from above the carriage at the rear side of the cab, and after replacement, put the damaged tire back to the spare tire position. Currently, the common methods are manual labor or using a lifting hook. Truck tires are heavy, manual operation is laborious, the operation of the lifting hook requires a large space, and a dedicated power source is needed. Summary of the Invention

[0003] The purpose of the present invention is to provide a device that saves time and effort and does not require a dedicated power source.

[0004] To achieve the above purpose, the solution adopted by the present invention is: an auxiliary handling device for replacing truck tires. This device can be fixedly installed on the side of the truck carriage, with a fixed column as the frame. The fixed column can be connected to a tire-carrying basket through a pulley on the side wall. Both ends of the fixed column are connected to two foldable columns through rotating pairs. There is a fixed pulley on the upper column, which is connected to the fixed pulley of the fixed column through a belt drive. The fixed pulley is connected to the fixed pulley in another set of the same device, so as to achieve the purpose of lifting the damaged tire by using the gravity of the left spare tire when it comes down. Brief Description of the Drawings

[0006] Figure 2 This is the top view of the present invention.

[0007] In the figure: 1 - tire; 2 - foldable column; 3 - fixed pulley of the foldable column; 4 - belt; 5 - carrying basket; 6 - rotating pair; 7 - fixed column; 8 - foldable column; 9 - side of the carriage; 10 - brake pin; 11 - left pulley of the carrying basket; 12 - telescopic tube of the carrying basket; 13 - middle sliding wheel of the carrying basket; 14 - fixed pulley of the fixed column Detailed Description of the Invention

[0008] The present invention will be further described in detail below with reference to the accompanying drawings.

[0009] The implementation process of the present invention is as follows: When replacing the truck tire, the carrying basket 5 is pulled open through the telescopic pipe of the carrying basket, and the foldable columns 2 and 8 are unfolded around the rotating pair 6. The spare tire is placed in the left carrying basket 5 of the device, and the brake pin 10 is installed to position the tire. At the same time, the damaged tire is placed in the carrying basket of the right device in the same way. When lowering the tire, the carrying basket smoothly slides down under the action of the pulleys 11, 13, and 14 of the column, driving the rotation of the fixed pulley of the foldable column. This rotation is transmitted to the right device through the belt 4, lifting the damaged tire onto the carriage to complete the auxiliary handling process.
