Description

Description: FIELD OF THE INVENTION The present invention relates to a hook for lifting a cabin of a working vehicle, and more particularly to a hook for lifting a cabin of a working vehicle with improved mounting strength. .

2. Description of the Related Art Conventionally, there is a work vehicle of a type in which a cabin is removed for maintenance work or the like, and a hoisting hook is provided on a roof of the cabin of this type. The hook is formed in an inverted U-shape by bending a metal bar, and both ends are welded to a roof member, and an intermediate portion is projected upward through a roof panel.

Further, a reinforcing rib is provided on the roof panel by press working, and a hook is projected from an insertion hole formed in the rib to weld the intermediate portion between the insertion hole and the hook, and a lower end of the hook is attached to the roof member. There is also known one in which the mounting strength is improved by welding the parts.

[Problems to be Solved by the Invention] The above-mentioned conventional hook which is welded to both the roof member and the roof panel has an improved mounting strength, but the inverted hook protrudes from the insertion hole formed in the rib of the roof panel. When the U-shaped hook is welded to the periphery of the insertion hole, the interval between the pillar portions of the hook projecting in parallel from the roof panel is small, so that it is difficult to perform welding work at the portion where the pillar portions face each other. Therefore, a portion that is not welded is formed at the opposed portion, which is not only aesthetically unfavorable, but also causes rainwater or the like to enter the space between the roof member and the roof panel from the gap between the hook and the insertion hole, causing rain leakage, and causing the roof member to leak. Rust is generated on the surface and causes corrosion.

Therefore, technical problems to be solved in order to prevent the intrusion of rainwater and the like to eliminate the cause of rust generation and to improve the livability and durability of the cabin arise, and the present invention solves the problem. The purpose is to solve.

Means for Solving the Problems The present invention has been proposed to achieve the above object, and a hook is fixed to a roof member of a cabin detachably formed on a work vehicle, and the hook is provided. In a hook for lifting a cabin of a working vehicle projecting upward through an insertion hole formed in a roof panel, a flat plate is fixed to the roof member to form a projecting piece, and an upper portion of the projecting piece is attached to the roof. Projecting outward from the insertion hole of the panel, forming a locking hole in the upper part to form a hook for lifting,
A hook for lifting a cabin of a working vehicle, wherein the hook and the roof panel are fixed to each other to reinforce a roof member of a cabin.

[Operation] According to the present invention, a lower portion of a lifting hook formed by drilling a locking hole in a flat plate is fixed to a roof member of a cabin of a working vehicle, and projects upward through an insertion hole of a roof panel. Let me. Then, an intermediate portion of the hook passing through the insertion hole is fixed to the roof panel.
When this fixing is performed by means of welding, the hook is flat, so that welding can be performed over the entire periphery of the fixing portion, and thus the gap between the roof panel and the hook is completely formed. The weld can be shielded, and the fixation of the two strengthens the roof member of the cabin strongly.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. For convenience of explanation, technical matters belonging to the related art will be described at the same time.

In FIG. 1, reference numeral (1) denotes a cabinet which is detachably formed on an upper cover (2) of a vehicle body. Reinforcing ribs (4) provided on the roof panel (3) of the cabin (1) are disposed in the front left / right direction, extend rearward from both left and right sides to form a U-shape, and form left and right sides. Lifting hooks (5), (5), (5), (5) are erected at front and rear portions.

The lifting hook (hereinafter simply referred to as a hook)
As shown in FIGS. 2 and 3, (5), (5), (5), and (5) show the hooks of a crane or the like hooked on flat tabs (6), (6), (6), and (6). The holes (7) (7) (7) (7) are drilled and the front roof frame (8) at the top of the cabin (1)
It is welded to the roof members (10) (10) installed in parallel to the left and right between the and the rear roof frame (9). On the other hand, a roof panel (3) that covers the front and rear roof frames (8) and (9) from above is provided with reinforcing ribs (4) corresponding to the roof members (10) and (10). The hook (5) (5) (5) is attached to the rib (4).
The insertion holes (11), (11), (11), and (11) corresponding to (5) are opened, and the hooks (5), (5), (5), and (5) are projected upward. In this embodiment, welding means is used for fixing the hooks (5), (5), (5), (5) and the roof panel (3). In such a case, since the hooks (5), (5), (5), and (5) are in the form of a flat plate, welding work is performed over the entire circumference of the insertion holes (11), (11), (11), and (11). Is easy and the hook (5) (5) (5)
The space between (5) and the insertion holes (11), (11), (11), (11) is completely sealed.

As shown in FIG. 2, a lining (12) is attached to the ceiling portion inside the cabin (1) for heat insulation and sound insulation. The lining (12) is the front roof frame (8)
Fold the rear end part (8a) of the roof member (10) (1
0) and a lining (12)
Insert the front end of Also, the rear end of the lining (12) is the same as the front end of the rear roof frame (9).
a) and the roof member (10)
According to the clip (13) (13) ..., the roof member (1
0) (10) crimped.

The left and right ends of the lining (12) are inserted and held in recesses (14a) (14a) provided in the left and right roof frames (14) (14) as shown in FIG.

As shown in FIG. 5, the clips (13) (13) are engagement holes (15) formed in the roof members (10) (10) along the ribs (4) of the roof panel (3). (15) Since it is screwed or press-fitted into and fixed to the roof panel (3), it does not protrude from the roof panel (3), does not impair the aesthetic appearance, and is extremely easy to mount.

The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified one.

[Effects of the Invention] In the present invention, as described in detail in the above-described embodiment, the hook for lifting is formed by a plate-shaped projecting piece.
When the hook is fixed to the roof panel, for example, when it is fixed by welding means, it can be welded over the entire circumference of the hook. Accordingly, unlike the conventional case using the U-bolt-shaped hook, there is no difficult-to-weld portion, and both can be firmly fixed. In this way, the roof member of the cabin is reinforced. Furthermore,
The insertion hole formed in the roof panel is completely sealed, has a remarkably aesthetic appearance, does not allow rainwater to enter, prevents rust, and improves durability. In addition, various effects are exhibited, such as a larger welding area as compared with a U-bolt hook, and an improvement in mounting strength and reliability.
