Description

[Detailed explanation of the invention] (Field of industrial application) This invention consists of a vehicle body constructed by connecting the engine and transmission case in a separable manner, like a tractor or forklift vehicle. Relating to a vehicle with a reinforcing frame along.

(Prior art) In tractors and forklift vehicles whose vehicle bodies are constructed by connecting engines and transmission cases that can be divided into front and rear sections, reinforcing frames are installed along the left and right sides of the vehicle body for reinforcement. . The reinforcing frame is connected to the vehicle body at its front and rear ends. Further, in some forklift vehicles, the front and rear ends of a reinforcing frame are connected to a lift device or a balance weight.

On the other hand, if the floor of the driver's seat is high from the ground,
Steps for getting on and off the vehicle are usually provided, and because they are installed on the left and right sides of the driver's seat near the center of the vehicle, they are located between the front and rear ends of the reinforcing frame. The step for getting on and off the vehicle is provided with a support member that supports the footplate from below because the footboard protrudes outward from the left and right sides of the vehicle body and is easily bent. Conventionally, the support member has been connected to the underside of the vehicle body.

(Problem that the invention aims to solve) The vehicle body is sometimes divided into front and rear parts to maintain and repair the transmission case, but the reinforcing frame and steps for getting on and off are in the way and need to be removed. The effort required to attach and detach it was troublesome. Particularly in vehicles such as forklift vehicles in which the reinforcing frame is also connected to a balance weight or a lift device, the number of man-hours required for its removal is increased. Further, when the step for getting on and off the vehicle is attached to the underside of the vehicle body, the operator has to crawl under the vehicle body to remove it, which is troublesome.

In view of the above, an object of the present invention is to facilitate the work of attaching and detaching the reinforcing frame and the step for getting on and off when the vehicle body is divided.

(Means for Solving the Problems) The present invention is characterized by the technical means taken to solve the problems of the prior art. A pair of left and right reinforcing frames 11 are arranged in the front-rear direction along
In a vehicle in which a step 15 for getting on and off is provided between the front and rear ends of the vehicle, each reinforcing frame 11 is composed of two front and rear members 11a, 11b, and each of the two front and rear members 11a, 11b is provided with a removable mounting member for the step 15 for getting on and off. Connected to the front and back so that they can be divided freely,
And each step 15 for getting on and off is attached to each reinforcing frame 11.
The point is that it protrudes further outward.

(Function) When dividing the vehicle body 6 into front and rear parts, the reinforcing frame 11 is also divided and connected by attaching and detaching the step 15, so that the step 15 and the reinforcing frame 11 are not separately removed from the vehicle body 6. can be divided into front and back.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

1 and 2 show a forklift vehicle, which is equipped with a lift device 1 at the front end and a balance weight 2 at the rear end. Further, a vehicle body 6 is constructed by connecting a transmission case 3, a clutch case 4, and an engine 5 in a front and rear series so as to be freely divisible. 7
is the front wheel and 8 is the rear wheel. A rear axle frame 10 that projects rearward is attached to the left and right side surfaces of the engine 5. A pair of left and right reinforcing frames 11 made of square pipes are attached along the left and right sides of the vehicle body 6. A pair of front and rear columns 12 are detachably installed on the upper surface of each reinforcing frame 11.
A safety frame 14 that covers the driver's seat is configured by attaching a top plate 13 to the upper end. A pair of steps 15 are provided on the left and right sides for getting on and off the driver's seat. Further, a bonnet 17 that covers the engine 9 and radiator 16 is provided at the rear end of the vehicle body 6.

The pair of left and right reinforcing frames 11 each include a first member 11a on the front end side and a second member 11 on the rear end side.
The first member 11 on the left and right is formed of two members, the front and rear of b.
The inner surface of the front end of a is connected by a connecting plate 18, and the connecting plate 18 is bolted to the front end surface of the mission case 3. Further, a bracket 19 extends downward from the front end of each first member 11a, and the lower end of a column 20 of the lift device 1 is connected to the bracket 19.

Further, each second member 11b is bolted to the left and right side surfaces of the engine 5.

Then, the rear end portion of the first member 11a and the second member 1
The front end of 1b is connected to the step 15 as shown in FIGS. 3 and 4. The step 15 includes a step board 21 extending outward from the left and right, a side wall 22 extending upward from the inside of the step board 21, and an upper wall 23 extending inward from the upper end of the side wall 22.
and a support member 24 formed separately from the footboard 21.
Equipped with. The support member 24 includes a joint portion 25 that joins the lower surface of the footboard 21 and the inner surface of the side wall 22, and a mounting portion 26 that extends back and forth from the upper end of the joint portion 25.
and has. Then, the side wall 22 of step 15
is connected to the outer wall of the first member 11a and the outer wall of the second member 11b by bolts 27. In addition, the mounting portion 26 of the support member 24 in step 15
is joined to the lower wall of the first member 11a and the lower wall of the second member 11b, while the upper wall 2 of the step 15
3 is joined to the upper wall of the first member 11a and the upper wall of the second member 11b. A bolt 28 passes through the mounting portion 26, the first member 11a, and the upper wall 23, and a nut 29 is screwed onto the end of the bolt 28.
Further, the bolt 30 is also passed through the mounting portion 26, the second member 11b, and the upper wall 23, and a nut 3 is inserted at the end of the bolt 30.
1 is screwed on. As a result, the first member 11
a and the second member 11b are separably connected by a step 15. In addition, the side wall 22, the upper wall 2
3. A mounting member is constituted by the mounting portion 26 and the like.

Therefore, when dividing the vehicle body 6 into front and rear parts for maintenance inspection or repair of the clutch, for example, the bolts 28, 3
By unscrewing the reinforcing frame 11 and removing the step 15, the reinforcing frame 11 can also be divided into two parts, a first member 11a and a second member 11b. Therefore, there is no need to separately attach and detach the step and reinforcing frame from the vehicle body as in the conventional case, and work efficiency can be improved. Also,
Since the step 15 is also connected to the reinforcing frame 11 rather than to the underside of the vehicle body 6, there is no need to crawl under the vehicle body when attaching or removing it as in the past.
It is easy to attach and detach.

In addition, as shown in the fourth figure, the square pipe-shaped reinforcing frame 1 is assembled with bolts 28, 30 and nuts 29, 31.
In the case where the reinforcing frame 11 is sandwiched, a collar may be provided that surrounds the bolts 28, 30 and is sandwiched between the upper and lower walls of the reinforcing frame 11 in order to prevent the reinforcing frame 11 from being compressed and deformed.

Furthermore, FIGS. 7 and 8 relate to an embodiment different from those shown in FIGS. 3 and 4, in which the first member 11a and the second member 11b are connected by a step 15 for getting on and off. The difference is that first, a connecting block 32 is inserted inside the opposing ends of the first member 11a and the second member 11b. Then, the upper wall 23 of the step 15, the upper walls of each of the first and second members 11a and 11b, and the connecting block 32 are fastened with bolts 33 and 34. Further, by fastening the mounting portion 26 of the step 15, the lower walls of the first and second members 11a and 11b, and the connecting block 32 with the bolts 35 and 36, the first member 11a and the second member 11b are connected to each other.
and are connected in a divisible manner. Connection block 3
2, the connection between the first and second members 11a and 11b is made firm.

As shown in FIGS. 5 and 6, the balance weight 2 has a protruding portion 2a extending rearward from the center of its lower end, and the protruding portion 2a is held between the pair of left and right rear axle frames 10, and the protruding portion 2a extends in the axial direction. The rear axle frame 10 and the protruding portion 2a are connected to each other by bolts 39 having a horizontal direction. In addition, a recess 37 is formed on the left and right sides of the balance welt 2 so that the rear end of the reinforcing frame 11 fits therein, and a bolt 38 whose axial direction is the horizontal direction is attached to the reinforcing frame 11.
and the side ends of the balance weight 2 are connected. That is, since the axial directions of the mounting bolts 36 and 38 of the balance weight 2 are all transverse, all the axial directions of the mounting bolt screw holes of the balance weight 2 are also transverse. With this, in order to attach balance weight 2,
Compared to mounting with bolts whose axial directions are different from front to back, lateral, and up and down, the relative positions of the screw holes of the balance weight 2 can be machined with high precision, making the installation appropriate and easy.

(Effects of the invention) According to the invention, each reinforcing frame 11 on the left and right sides of the vehicle body 6 is constituted by two front and rear members 11a, 11b, and these two front and rear members 11a, 11b are mounting members for the step 15 for getting on and off. Since the front and rear parts 11a and 11b are connected to each other so that they can be divided into two parts, when the car body 6 is divided into the front and rear parts for inspection etc. of the car body 6, it is only necessary to disconnect the two front and rear members 11a and 11b by the mounting members. Reinforcement frame 1 on both left and right sides of 6
1 itself from the vehicle body 6, and the number of man-hours required for dividing the vehicle body can be reduced. Therefore, even if the front and rear ends of the reinforcing frame 11 are connected to a lift device or a balance weight, such as in a forklift vehicle, there is no need to attach or detach them when dividing the vehicle body 6, which greatly reduces labor. It can be reduced.

Further, since the mounting member for the step 15 for getting on and off the vehicle is removable, the step 15 can be easily attached and detached. Furthermore, since the step 15 projects laterally from the reinforcing frame 11, it is easy for the operator to get on and off the machine.
