Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a self-propelled balancer having a balancer mounted on a self-propelled carriage that is used for loading and unloading heavy objects or moving a short distance at a construction site or a cargo handling work site.

[0002]

[Prior art]

 A mobile balancer in which a balancer is mounted on a moving carriage is described in, for example, Japanese Patent Publication No. 55-40519, but this moving carriage is simply provided with wheels and is manually moved. Therefore, the present applicant has already filed an application for a self-propelled balancer in which a balancer is mounted on a self-propelled moving carriage equipped with a battery and a motor, in Japanese Patent Application No. 5-15202.

[0003]

[Problems to be solved by the device]

 In the self-propelled balancer, the position of the balancer on the trolley is approximately the center of the trolley in consideration of the stability when the balancer is used. The equipment necessary for driving is installed, and the balancer becomes an obstacle when performing maintenance and inspection of these equipment. Therefore, it is an object to move the balancer from the mounting position to the end of the bogie with a simple operation so that the inside of the bogie can be opened.

[0004]

[Means for Solving the Problems]

 In a self-propelled balancer in which a balancer 3 is mounted on a bogie 2 equipped with a traveling device 1, an intermediate rail 8 in which front and rear engaging portions 6 and 7 are formed on left and right side frames 4 and 5 of the bogie 2 and an intermediate rail thereof. 8 are vertically sandwiched, and upper and lower guide rails 9 and 10 are provided, and a mounting base 11 of the balancer 3 is provided with rollers 12 and 13 which are fitted to the engaging portions 6 and 7 of the intermediate rail 8 from above and below, and the balancer 3 is tilted. The rollers 12 and 13 are disengaged from the engaging portions 6 and 7 and contact the upper and lower guide rails 9 and 10, so that the balancer 3 can be moved to the front side or the rear side of the trolley 2 in a tilted state. .

[0005]

[Operation and effect of the device]

 When the balancer 3 is fixed at a predetermined position of the truck 2, the rollers 12 and 13 provided on the left and right sides of the mounting base 11 of the balancer 3 are provided on the left and right side frames 4 and 5 on the truck 2 side and the intermediate rail 8 is provided. The balancer 3 is positioned with respect to the trolley 2 in a state where the balancer 3 is fitted to the engaging portions 6 and 7 provided on the front, rear, left and right, and is fixed by another fixing means.

When moving the balancer 3 on the carriage 2, first, the fixing means is removed, and then the balancer 3 is tilted with respect to the carriage 2. Then, the rollers 12 and 13 provided on the mounting base 11 of the balancer 3 are disengaged from the engaging portions 6 and 7 formed on the intermediate rail 8 of the carriage 2 and come into contact with the upper and lower guide rails 9 and 10, and the balancer 3 is further moved. By moving laterally in this posture without tilting, the rollers 12 and 13 can move lightly while rolling along the upper and lower guide rails 9 and 10.

Conversely, when the balancer 3 is moved to a predetermined position of the carriage 2 and fixed, the rollers 12 and 13 of the intermediate rail 8 can be moved by moving the balancer 3 to the predetermined position of the carriage 2 while tilting the balancer 3. The fixed position is immediately determined by fitting the engaging portions 6 and 7. Then, it may be fixed by a fixing means.

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings. The trolley 2 is equipped with a traveling device 1 composed of crawlers on the left and right sides, and a box-shaped vehicle body frame 14 is internally provided with a battery, a motor, a control panel and the like so that the trolley 2 can travel by itself. Outside the left and right side frames 4 and 5 that form the vehicle body frame 14, an upper guide rail 9, an intermediate rail 8 and a lower guide rail 10 that project laterally in parallel with the front-rear direction (travel direction) of the bogie 2. Is provided. The intermediate rail is formed with engaging portions 6 and 7 formed of notched grooves on the front side and the rear side, and the lower guide rail 10 is provided with end plates 15 and 16 which are erected upward at the front and rear ends. .

A U-shaped mount 11 is fixed to the lower end of the balancer 3, and the balancer 3 is mounted on the carriage 2 so that the mount 11 covers the body frame 14 from above. Rollers 12, 13 are rotatably supported on the inner surface of the mount 11 facing the left and right side frames 4, 5 of the vehicle body frame 13 at the same intervals as the intervals of the engaging portions 6, 7 of the intermediate rail 8. The balancer 3 is set at a predetermined position on the carriage 2 at a position where the rollers 12, 13 are partially fitted into the engaging portions 6, 7 from above and below.

The balancer 3 is positioned with respect to the carriage 2 by fitting the rollers 12 and 13 to the engaging portions 6 and 7, and a spacer 17 is interposed between the vehicle body frame 14 and the mounting base 11 and is mounted with bolts 18. The base 11 and the body frame 14 are integrally fixed.

When moving the balancer 3 forward (to the left in FIG. 1), the bolt 18 is removed and the balancer 3 is tilted forward. Then, as shown in FIG. 3, the rollers 12 and 13 can move out of the engaging portions 6 and 7 of the intermediate rail 8. After that, the balancer 3 is pulled forward and one of the rollers 12 moves until it comes into contact with the end plate 15 of the lower guide rail 10, and the inside of the vehicle body frame 14 is opened upward and the internal battery and roller , Maintenance and inspection of the control panel, etc. can be performed. Also, if the balancer 3 is lifted at this position, it can be removed from the carriage 2.

To fix the balancer 3 in the original position, the balancer 3 is pushed forward to the center of the vehicle body frame 14 while being tilted forward, and the rollers 12 and 13 are engaged while the tilt of the balancer 3 is returned. The parts 6 and 7 are fitted to each other so as to be in a predetermined position on the carriage 2. After that, the bolt 18 is tightened to integrate the balancer 3 and the carriage 2.
