DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for assembling equipment to a vehicle frame, and more particularly, to assembling various mounted equipment such as a motor for driving a hydraulic pump to a vehicle frame of a vehicle such as a battery forklift and a charging device. The present invention relates to a method and an assembly structure thereof.

[0002]

2. Description of the Related Art Conventionally, in an industrial vehicle such as a battery forklift, a medium-sized and relatively heavy pump motor for driving a hydraulic pump, a charging device for charging a battery, and the like have a weight balance with respect to a main frame. It is fixed on both left and right sides of the frame for consideration.

FIG. 6 shows a pump motor 61 attached to a frame 60.
It is a figure showing the state where it was assembled. In FIG.
A mounting chamber 63 is formed on the outer surface of the frame 60 extending in the front-rear direction by welding a rectangular frame body 62 so as to be isolated from other devices, and a pump motor 61 is fixed to the mounting chamber 63. I have. The pump motor 61 is fixed by fixing the leg of the pump motor 61 and the bottom plate 62 a of the frame 62 with bolts 64. The pump motor 61 is generally assembled on an assembly line.

[0004]

The width of the storage room 63 is relatively long because there is no member provided outside the frame 60 and attached to the front and rear. On the other hand, the depth of the mounting chamber 63 is small because the frame 62 cannot protrude much outside due to the relationship with the vehicle width. That is, when the pump motor 61 is accommodated, the distance between the both side plates 62b of the frame 62 and the pump motor 61 can be kept large to some extent, but the distance between the frame 60 (outer surface) and the pump motor 61 is very narrow. .

Therefore, when the pump motor 61 is fastened to the mounting chamber 63 with the bolt 64, the back side of the pump motor 61,
That is, since the frame 60 side cannot be seen with the eyes and is a very narrow space, the positioning, bolt insertion and bolt tightening operations are groping, and the tools are difficult to use, which is very troublesome and troublesome. Was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems, and has been made in consideration of the above-described problems, and has an object mounted on a vehicle which can easily and reliably fix a device to a mounting portion having no depth provided on a vehicle frame. An object of the present invention is to provide a device assembling method and an assembling structure thereof.

Bolt insertion holes 25 are formed in the front mounting plate 24 at two locations on the left and right. In the present embodiment, the rear mounting plate 21 and the front mounting plate 24 constitute a mounting portion.
The space surrounded by the main frame 11, the side plate 13, the rear side plate 17b, and the front side plate 23 is
And

The housing chamber 26 shown in FIG. 2 houses a motor M in which a hydraulic pump P is drivingly connected to a drive shaft. still,
The accommodation room 26 formed on the left side not shown in FIG.
A charging device for charging a battery cell mounted on the forklift 1 is accommodated. Since the method of housing and assembling in the housing chamber 26 is the same as the method of housing the motor M, only the housing of the motor M will be described.

The motor M is fixed to a substrate 31 made of a square steel plate. The motor M is disposed substantially at the center of the board 31, and the leg of the motor M and the board 31 are connected and fixed by bolts 32. Bolt insertion holes 33 as connection fixing portions are formed at four corners of the board 31 at positions separated from the motor M, and each bolt insertion hole 33 accommodates the board 31 in the accommodation chamber 26 and holds Corresponding to the insertion holes 2 formed in the mounting plates 21 and 24
2 and 24 are opposed to each other. Then, the substrate 31 is mounted on the mounting plates 21 and 24, and the insertion holes 22, 24,
The board 31, that is, the motor M is assembled to the frame 11 by inserting a bolt 34 as a connecting member into 33 and screwing a nut 35 also as a connecting member.

An elliptical wiring inlet 40 is formed in the main frame 11 forming the accommodation chamber 26. The wiring inlet 40 is connected to the motor M accommodated in the accommodation room 26.
This is for introducing the power supply line into the room. A grommet 41 made of 66 nylon is fitted in the wiring inlet 40.

FIG. 5 shows that the grommet 41 is connected to the wiring inlet 40.
It is a cross-sectional view showing the state where it was fitted. The grommet 41 has a cylindrical portion 41 a having the same shape as the wiring inlet 40.
And a flange 41 formed at the front of the cylindrical portion 41a.
b. A pair of cuts 42 are formed on both left and right and upper and lower sides of the cylindrical portion 41a, and a flexible holding piece 43 formed to protrude outward between the pair of cuts 42. Each of the holding pieces 43 is formed in a step-like shape, and bends inward when an outwardly protruding portion is pressed inward. Therefore, when the grommet 41 is inserted into the wiring introduction port 40 with the holding piece 43 facing the wiring introduction port 40, the holding piece 43 bends inward and protrudes outward when passing through the wiring introduction port 40. The grommet 41 is formed by the holding piece 43 and the flange 41b.
Is attached to the wiring introduction port 40 in a state where the is sandwiched.

The accommodation room 26 is closed by a cover 50 as shown in FIG. That is, the locking pieces 51 are formed on the rear and front side plates 17b and 23,
A screw hole 52 is formed in the locking piece 51. Then, the screw hole 52 is inserted from the cover 50 into the screw hole 52.
The cover 50 is attached by screwing the screw 53 onto the cover 50.

Next, the features of the forklift constructed as described above will be described below. (1) In the present embodiment, the substrate 31 on which the motor M is fixed.
Are mounted on the mounting plates 21 and 24, and the substrate 31 and the mounting plates 21 and 24 are bolted to the four corners of the substrate 31 and the nuts 3.
5 and fixed. Therefore, when the motor M is housed in the housing room 26, the motor M and the side plates 17b, 23 have a certain wide gap and are visible. Therefore, the assembling can be performed in a relatively large space while visually recognizing. As a result, a series of assembling operations such as positioning, bolt insertion, and bolting with a tool can be performed very easily and reliably.

(2) In the present embodiment, the rear mounting plate 21
There is an interval (space) between and the front mounting plate 24. Therefore, when the substrate 31 to which the motor M is fixed is accommodated in the accommodation room 26, the substrate 31 is obstructed downward (the bottom plate 62 shown in FIG.
Since there is no a), it is easy to guide the motor M toward the back of the accommodation room 26. Moreover, the substrate 3 is mounted on the pair of mounting plates 21 and 24.
When the device 1 is placed, the bottom surface of the substrate 31 can be touched, so that the positioning operation of the substrate 31 can be performed very easily.

(3) In the present embodiment, the power supply line connected to the motor M assembled in the accommodation room 26 is connected to the main frame 1
A grommet 41 made of 66 nylon was fitted into the wiring introduction port 40 formed in No. 1. Therefore, the power line is not rubbed against the steel plate and is not damaged, and the power line is reliably protected.

It should be noted that the present invention is not limited to the above embodiment, but may be implemented in the following modes. (1) In the above embodiment, the substrate 31 is mounted on the pair of front and rear mounting plates 21 and 24, but may be configured by one mounting plate corresponding to the bottom plate 62a shown in FIG.
