Abstract

PURPOSE:To set a car body horizontally in a short time even in the case of the working at an inclined place. CONSTITUTION:In a working vehicle, outriggers for stabilizing a car body at the time of working are provided in front and rear of a lower travelling body, which can travel by itself. In this working vehicle, inclination of the vehicle in the fore and aft direction and the right and left directions are detected by a fore and aft inclination detecting unit 13 and a right and left inclination detecting unit 14. Length of a front, rear, right and left outrigger arms 6 are detected by outrigger length detecting units 18. A controller 10 computes a required extension and shrinkage quantity of a right and a left jack cylinders provided in the front and the rear outriggers, and the controller 10 controls a control valve 15, which is provided per each jack cylinder, in response to a result of computing. Even in the case of working at an inclined place, a car body can be thereby set at a horizontal position in a short time.

However, in the above-described conventional vehicle body horizontal installation device, when the vehicle body is installed horizontally, first, the lifting jacks are set to the maximum extension state, and then the vehicle body is detected based on the signal from the inclination detecting means. The body is installed horizontally by reducing the lifting jack so that it becomes horizontal, and there is a problem that work efficiency is poor because it takes time from the start of operation until the body is installed horizontally. The present invention has been made in order to improve such a problem, and an object thereof is to provide a vehicle body horizontal installation device for a work vehicle having an outrigger capable of horizontally installing the vehicle body in a short time.

The operation will now be described with reference to the flow chart shown in FIG. 4. When the work vehicle is stopped on a sloping ground and the crane boom 3 is used for the work, the outrigger arm 6 is used as much as possible in order to stabilize the vehicle body. Extend long. Then, four jack cylinders 7 are simultaneously extended to the extent that the tires float. On a sloping ground, the vehicle body is tilted in this state. Here, the automatic horizontal switch 12 is turned on. Now, step 101 is entered. As a result, the controller 10 checks in step 102 whether the horizontal flag is OK. If the horizontal flag is OK, it is determined that the work vehicle is horizontally installed, and the vehicle body horizontal installation control ends. When the horizontal flag is determined to be NG at step 102, the routine proceeds to step 103, where the horizontal control routine is executed.

The horizontal control routine is executed as shown in FIG. 5, and at step 201, it is judged whether the inclination α of the vehicle body 1a in the front-rear direction is smaller than a ° and the inclination β in the left-right direction is smaller than a °. If it is larger than a °, the operation time t 1 of the control valve 15 provided for each jack cylinder 7 is set in step 202, and the control valve 15 is operated for t 1 seconds in step 203. If it is smaller than a °, the routine proceeds to step 204, where it is judged whether the front-back inclination angle α is smaller than b ° and the left-right inclination is smaller than b °.
If it is larger, the routine proceeds to step 205, where the operating time of the control valve 15 provided for each jack cylinder 7 is set to t 2 which is smaller than t 1 , and at step 206 the control valve 15 is operated for t 2 seconds.

On the other hand, in consideration of the case where the vehicle body 1a does not become horizontal even if the jack cylinder is fully extended due to the steep inclination, the timer is set in step 104, and the timer is added in step 105 during the horizontal control routine. In step 106, it is checked whether the timer has timed out, and if not, the horizontal control routine is continued. When it is determined in step 106 that the time is over, the routine proceeds to step 107, the alarm device is activated, and the control routine is ended.
