Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trolley for tire attachment / detachment that is convenient for improving the efficiency of wheel removal work and wheel reset work during vehicle maintenance.

[0002]

[Prior art]

 When servicing a vehicle, such as during a vehicle inspection, it is common to first remove the wheels lifted by the lift for maintenance, and finally reset the wheels to finish the maintenance work. Since it is normal to throw out the wheel hub nuts and wheels that have been removed in step 1 below the lift, it is often the case that the wheel hub nuts are searched or the positional relationship of the wheels becomes unclear when resetting. The workability is significantly impaired. Therefore, the applicant first developed a moving table for automobile maintenance in which the wheel hub nut is not searched for during resetting and the positional relationship of the wheels is not known, and the application was filed as Japanese Patent Application No. 3-102934. It has a drawback that the structure is complicated, the size is large, and the cost is high.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems and to properly arrange the wheel hub nuts and wheels that have been removed during wheel removal to remove wheels during vehicle maintenance. It is an object of the present invention to provide a small and lightweight trolley for tire attachment / detachment, which can improve the efficiency of wheel resetting work and has a simple structure.

[0004]

[Means for Solving the Problems]

 In the truck for tire mounting and demounting work according to the present invention, which solves the above-mentioned problems, a caster is attached to a pipe frame having both wing portions as a tire holding portion of a forward rising shape, and a tire cage is attached to an intermediate portion of the pipe frame. It is characterized in that a strut for standing upright is installed upright and a tray is attached to the upper part thereof.

[0005]

[Action]

 Such a truck for tire removal work is moved by casters to the tire mounting position of the vehicle body lifted by the lift, and then the wheel hub nut is removed in the discharge direction so that the wheel hub nut to be removed is stored in the tray. Move the tray almost directly below. Then, loosen the wheel hub nut with a wrench to remove it from the hub bolt, eject the wheel hub nut from the wrench socket, store it in the tray, and remove the tire from the hub bolt. Place it on the ear holding part and automatically lean it on the strut for leaning the tire by the inclination of the rising tire holding part and hold it, move it to the position of the next tire with casters and do the same as above. Then, remove the next tire, and hold the next tire side by side next to the previously removed tire. In this way, when all the tires are removed and the tires are held by the tire holding portion, the automobile body is sent to the maintenance process for maintenance. Then, when the maintenance of the automobile body has been completed to a predetermined stage, the tires held in the tire holder are sequentially moved to the respective tire positions below the automobile body, and the tires are sequentially attached to the automobile body, and then from the tray. Tighten the wheel hub nut with a wheel hub nut removal wrench.

[0006]

【Example】

 Next, the present invention will be described in detail based on the illustrated embodiment. Reference numeral 1 denotes a pipe frame having both wing portions which are raised tire-holding portions 2 and 2, and each tire holding portion 2 of the pipe frame 1 holds two tires arranged in parallel. There is. Reference numeral 3 denotes four casters attached to the pipe frame 1, and the casters 3 allow the pipe frame 1 to move freely while holding tires. Numerals 4 and 4 are stanchions for standing on a tire, which are erected from the middle portion of the pipe frame 1, and brackets 6 for pivotally mounting a pair of two rollers 5 are fixed to the upper portions of the stanchions 4, 4. Has been done.

Reference numeral 7 is a tray for accommodating hub nuts for wheels. An L-shaped guide rail 8 is attached to the bottom surface of the tray 7, and the roller 5 is provided between the guide rail 8 and the bottom surface of the tray 7. And the tray 7 is mounted between the upper portions of the columns 4 and 4 so as to be movable in the direction of both blade ends. Numeral 9 is a stopper provided at both ends of the guide rail 8 to prevent the tray 7 from being separated from the roller 5 by the stopper 9.

When the tire is replaced or the automobile body is maintained, the thus-configured one is moved by the caster 3 below the tire mounting position of the automobile body lifted by the lift. Then, when the wheel hub nut in the socket of the wrench is discharged, the tray 7 is moved substantially directly below the wheel hub nut in the discharge direction of the wheel hub nut so that the wheel hub nut is stored in the tray 7. Next, loosen the wheel hub nut with a wrench to remove it, store the wheel hub nut in the tray 7, remove the tire from the hub bolt, and place it on one of the tire holding parts 2 of the pipe frame 1 that is in the forward rising shape. The inclination of the holding portion 2 automatically leans against the columns 4 and 4 for leaning the tire to hold it.

Then, the work carriage is moved to the position below the next tire mounting position, the tire is removed in the same manner as described above, the hub nut for the wheel is stored in the tray 7, and the next tire is placed next to the tire that was previously removed. Hold side by side. When the tire on one side of the automobile is removed in this way, the work carriage is moved to the other side of the automobile and the tire is removed in the same manner as described above. Hold them side by side. When all the tires are removed in this way, the car body is sent to the maintenance process for maintenance, and after the repair, the work trolley is moved based on the tire rotation so that the tires can be mounted at the predetermined mounting positions.

[0010]

[Effect of device]

 Since the wheel hub nuts and wheels that have been removed during vehicle maintenance can be properly sorted out, it is possible to improve the work efficiency of a series of wheel removal work and wheel reset work during vehicle maintenance. , The removed tire was mounted on the tire holding part of the rising edge of both wing parts of the pipe frame on the strut for tire mounting in the middle part of the pipe frame so that the tire was stably held. It is possible to freely move it to a predetermined position without having a handle, and the tray is mounted between the upper parts of the stanchions so that it can move toward both wing tips. You can easily position the tray directly below the wheel hub nut in the ejection direction without moving it to the wheel hub that has been ejected from the wrench socket. A shall be accurately accommodated in the tray without the use hub nuts to fall to the floor. In addition, the pipe frame having both the wing portions as the raised tire holding portion has a merit that it has a simple structure, is small and lightweight, and can be provided at a low cost. Therefore, the present invention is of great practical value as a truck for tire mounting and demounting work that solves the conventional problems.
