Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a mounting bracket which is mounted on a crane base of a vehicle-mounted crane and fixes the crane base to a chassis side frame.

(Prior Art) This will be described with reference to FIGS.

A crane base 2 constituting the base of the frame of the on-vehicle crane 1 is placed on the upper surface of the chassis side frame 3 of the vehicle so as to be laterally mounted thereon, and is arranged so as to receive the chassis side frame 3. The two legs of the U-shaped fixture 6 provided with the above are inserted into the long holes 5 of the mounting bracket 4 provided with the long holes 5 crossing the chassis side frame 3 provided near the lower portion of the crane base 2 and tightened. It is designed to be fixed.

By securely attaching and fixing the crane base 2 to the chassis side frame 3 in this way, the vehicle-mounted crane 1 and the vehicle are integrated, and the crane operation can be performed safely.

(Problems to be Solved by the Invention) In mounting and fixing the crane base 2 to the vehicle, the position between the U-shaped fixing tools 6 is determined by the mounting bracket 4.
Is fixed uniquely by the position of the long hole 5, so that an appropriate mounting position of the on-vehicle crane 1 can be determined by exchanging accessory devices 7 such as a battery 7a and an air tank 7b already attached to the vehicle which is a completed vehicle. There is a problem that it is difficult to secure the position of the crane base 2 to be obtained.

Therefore, in order to secure an appropriate position of the crane base 2, it is necessary to relocate these accessory devices 7, which has led to a problem that the time and cost are very uneconomical.

(Means for Solving the Problems) In a vehicle-mounted crane, a crane base laid on the left and right chassis side frames of a vehicle is provided with a long hole located above the chassis side frame and crossing the chassis side frame. Attach a mounting bracket with additional slots spaced longitudinally of the frame, and attach the two legs of a U-shaped fixture that is positioned to receive the chassis side frame and that has external threads on each of its legs. The crane base is fixed to the chassis side frame by being inserted into the long hole of the mounting bracket and tightened.

(Operation) Since the mounting bracket of the crane base has an elongated hole and an additional elongated hole which is spaced apart in the longitudinal direction of the chassis side frame, a U-shaped fixture for receiving the chassis side frame exchanges the attached device. By selecting the long holes and inserting the two legs of the U-shaped fixture through these selected long holes and tightening, the crane base of the vehicle-mounted crane can be mounted and fixed to the chassis side frame of the vehicle.

(Example) A description will be given based on Figs. 1 to 4.

As conventional techniques, reference numerals 1 to 3 and 6 to 7 described and used in FIGS. 5 to 7 are the same and will not be described.

In FIG. 1, reference numeral 8 denotes a mounting bracket which is located above the chassis side frame 3 and has an elongated hole crossing the chassis side frame 3 and which is mounted on the crane base 2. Reference numeral 9 denotes a long hole, which is a long hole 9a on the crane base 2 side.
(Corresponding to the long hole 5 shown in the prior art) is provided with an additional long hole 9b separated in the longitudinal direction of the chassis side frame 3.

Although the long holes 9b are shown in a single row in FIG. 1, they may be added in a row in the longitudinal direction of the chassis side frame 3 to form a multi-row.

Next, a method of attaching and fixing the vehicle-mounted crane 1 to the vehicle will be described.

The crane base 2 is placed horizontally on the left and right chassis side frames 3 of the vehicle at the position where the vehicle-mounted crane 1 is at the optimal mounting position, and a U-shaped fixing device 6 for receiving the chassis side frame 3 is attached. The crane base 2 is fixed to the chassis side frame 3 by selecting the long hole 9 of the mounting bracket 8 that does not interfere with the device 7 and inserting and tightening both legs of the U-shaped fixture 6 into the long hole 9. is there.

2 (a) is generally used as the U-shaped fixture 6, but the plate member 10 and the bolt 11 may be used as shown in FIG. 2 (b), and as shown in FIG. 2 (c). Plate 10 'and bolt
11 'may be used.

Like the location of the battery 7a and other accessories 7c in FIG. 1, the elongated hole 9 of the mounting bracket 8 into which the leg of one end of the U-shaped fixture 6 is inserted, and the U-shaped fixture 6
The elongated holes 9 of the mounting bracket 8 into which the legs at the other end are inserted are arranged in another row, and the crane base 2 is chassis-sided so that the U-shaped fixing tool 6 interferes with the accessory 7. It may be fixed to the frame 3.

Another embodiment will be described with reference to FIGS.

Numeral 12 denotes a ladder-shaped bracket, and numeral 13 denotes a bracket for mounting the bracket 12 mounted on the crane base 2.

The method for mounting and fixing the vehicle-mounted crane 1 to the vehicle is as follows. On the upper side surface of the chassis side frame 3, select the long hole 9 where the U-shaped fixing tool 6 passes the accessory device 7 at the optimum mounting position of the vehicle-mounted crane 1. Place the bracket 12 on the
The crane base 2 is placed on the upper surface of the bracket 12, and the bracket 12 and the mounting bracket 13 are tightened and fixed.

(Effect) When mounting the on-board crane at the optimal position, the crane base can be attached and fixed to the chassis side frame without relocating the attached equipment.
Time and cost can be greatly saved, and the effect is great.
