Description

  The present invention relates to a shim mounting structure that is inserted between a body frame and a cabin in a forklift having a cabin.

  A forklift with a cabin in which a cabin is attached to the body of the forklift is known. For example, Patent Document 1 discloses a forklift with a cabin that is used in a refrigerated / frozen low-temperature warehouse, in which a box-shaped cabin is formed integrally with the vehicle body so as to cover the driver's seat at the rear of the vehicle body. Has been. The invention of Patent Document 1 is an invention in which a heat insulating material is attached to a portion where metal such as a metal cross in the cabin is exposed in order to prevent condensation in the cabin of a forklift with a cabin. Patent Document 1 describes that not only a heat insulation effect but also a vibration absorption effect can be obtained by using a heat insulating material made of a foam material. However, there is no particular mention regarding a specific mounting structure between the cabin and the vehicle body.

  Patent Document 2 aims to facilitate maintenance of a battery case disposed in a cabin in a forklift with a cabin. In the invention of Patent Document 2, the width of the cover of the battery case is made smaller than that of the battery case, and the gap between the cover of the battery case and the vehicle body is increased to interfere with the handle of the door when the cover is pulled up. Therefore, the cover can be easily lifted up and maintenance work can be performed efficiently. Patent Document 2 shows that the cabin is mounted on the vehicle body, but does not particularly refer to the mounting structure between the vehicle body and the cabin.

  As described above, in the forklift with a cabin, various studies have been made on the thermal insulation of the cabin and the arrangement in the cabin. However, studies have not been made on the mounting structure between the cabin and the vehicle body.

JP 2001-106490 A Patent No. 3877114

  The cabin is attached to the outside of the body frame so as to cover the body, and is fixed to the body frame by bolts. A gap is provided between the cabin and the vehicle body frame in order to improve assembly and allow manufacturing errors. Further, for the purpose of preventing looseness of the cabin and loosening of the bolts, shims are inserted in the gaps between the cabin and the vehicle body frame at the bolt fixing points. Conventionally, the shim has been attached by sliding the shim into a gap between the vehicle body frame and the cabin through a hole provided in the vicinity of the bolt fixing portion of the vehicle body frame, and fastening the bolt. However, with this method, the shim must be inserted by groping, and depending on the cabin and body layout, the car body frame or cabin must have a large cutout. If the cabin has a large cutout, the cabin design will be poor. There was a problem that a specially shaped shim had to be prepared.

  In view of the above circumstances, an object of the present invention is to provide a shim mounting structure that is easy to mount and has high working efficiency without providing a large cutout in a vehicle body frame or cabin.

  The inventor studied the above problems, and conventionally, one shim was inserted into each of the fixed places. However, the shim was changed to an elongated plate shape, and one shim was fixed to a plurality of places. It has been found that by fixing it to the location, it is not necessary to adjust the position by inserting a shim at each location, so that the work efficiency can be improved and the number of parts can be reduced by making the shim common. Further, the inventor can insert the shim from the outside of the cabin by replacing the shim insertion hole that has been provided in the vehicle body frame with a notch provided in the cabin wall surface. The work has been simplified, and since it is not necessary to provide a large cutout in the body frame, the present invention has been found to be advantageous in terms of strength and heat insulation.

The vehicle body frame is provided with first and second fixing holes for fixing the shim, and the first fixing hole is provided at a position corresponding to the shim insertion port,
The shim is in the shape of an elongated thin plate and is arranged so as to extend over the first fixing hole and the second fixing hole, and is bolted with the first fixing hole and the second fixing hole. ing,
The present invention relates to a shim mounting structure.

  In the present invention, it is preferable that the first fixing hole and the second fixing hole are provided apart from each other in the vertical direction.

  In the present invention, it is preferable that an opening for adjusting the shim position is provided in the middle in the vertical direction of the first fixing hole and the second fixing hole.

Further, the present invention is a method of attaching a shim between a vehicle body frame and a cabin in a forklift with a cabin in which a cabin is attached to the outside of the vehicle body frame,
The lower side surface of the cabin is provided so as to cover the side surface of the body frame,
The front or rear surface of the cabin is provided with a notch that is a shim insertion port for inserting a shim into the gap at a position corresponding to the gap between the lower side surface of the cabin and the side surface of the vehicle body frame. And
(1) A step of inserting the elongated thin plate-like shim into the gap from the shim insertion port,
(2) inserting the shim so as to reach a first fixing hole provided on a side surface of the vehicle body frame, and fixing the bolt with the first fixing hole;
(3) A step of adjusting the position of the shim, which is bolt-fixed in (2), so as to match the position of the second fixing hole provided on the side surface of the vehicle body frame by rotating the shim with the bolt fixing portion as a fulcrum. ,
(4) The present invention relates to a method including a step of bolting the shim whose position is adjusted in (3) with the second fixing hole.

  According to the present invention, an opening for adjusting the shim position is provided in the vicinity of the first fixing hole and the second fixing hole, and the position of the shim is visually observed through the opening in the step (3). It is preferable to adjust the position.

  Conventionally, it has been necessary to insert a shim through a hole provided in the body frame and fix it with bolts. According to the present invention, it is possible to insert the shim from the outside of the cabin while looking at the shim. Even if the bracket is welded to the bracket, it can be inserted and fixed without hindrance. Further, according to the present invention, it is possible to fix one place of the shim by fixing one place of the inserted shim and subsequently rotating the shim with the fixed place as a fulcrum. That is, the shim can be inserted and fixed easily and efficiently, and the burden on the operator is small. In addition, since it is not necessary to provide a hole for shim insertion in the body frame, the body frame can be excellent in strength and heat insulation. Furthermore, since shims can be shared and the number of parts can be reduced, it is advantageous in terms of manufacturing cost.

Since the shim insertion port S is provided at a position corresponding to the gap between the vehicle body frame 20 and the cabin side panel 10, the shim is inserted between the vehicle body frame and the cabin side surface through the shim insertion port S. Can do.

  FIG. 5 is a diagram schematically showing a procedure for inserting or fixing the shim. FIG. 5 is a view of the forklift as viewed from the cabin interior side, and the right side of the drawing shows the front of the forklift. The shim L is a long and thin plate-like metal member in which holes for penetrating bolts are formed near both ends. In the vehicle body frame 20, a first fixing portion and a second fixing portion are formed in advance as holes 21 and 22 for bolt penetration. The length, width, and thickness of the shim are not particularly limited as long as the shim can be inserted so as to reach the fixing hole 21 from the shim insertion port S and can be disposed so as to extend over the fixing hole 21 and the fixing hole 22. However, for example, the length can be about 200 to 300 mm, the width is 30 to 50 mm, and the thickness is about 0.8 to 3.2 mm.

  In the mounting process, first, the shim L is inserted into the gap between the vehicle body frame 20 and the cabin side panel 10 from the outside of the cabin through the shim insertion slot S (arrow with a circled number 1). The shim L is inserted, and when the bolt hole of the shim L reaches the fixing hole 21 of the vehicle body frame 20, the bolt is inserted from the outer side of the cabin to the vehicle body frame 20 through the shim L and fastened. As a result, one end of the shim L is fixed in the first fixing hole 21.

  Subsequently, the shim L is rotated downward with the bolt-fixed portion (first fixing hole 21) as a fulcrum (the arrow with the number 2 with a circle). Adjust the position until the bolt hole of the shim L reaches the second fixing hole 22, and when the shim L reaches the second fixing hole 22, the bolt is inserted from the side of the cabin through the shim L to the vehicle body frame 20. And conclude. The body frame 20 is provided with an opening 23 for position adjustment, and the position adjustment can be performed while viewing the position of the shim L through the opening 23. If necessary, it is also preferable to insert a tool or a hand from the opening 23 to move the shim L.

  In the illustrated example, the opening 23 for adjusting the shim position is a rectangular opening formed obliquely in the middle of the fixing holes 21 and 22 in the vertical direction, but the shim fixed in the first fixing hole 21 is used. The shape and the size are not particularly limited as long as the opening is provided on a trajectory through which the shim L passes when moving the L to the second fixing hole 22 and can visually observe or adjust the shim L. For example, the opening 23 may be an arc-shaped or fan-shaped opening, or may be a plurality of openings.

  In the illustrated example, a shim insertion port is provided on the front surface of the cabin. However, a shim insertion port can be provided on the rear surface of the cabin with the same configuration. In addition, the plurality of fixing points fixed by one shim are preferably provided in the vertical direction, but may not necessarily be in the vertical direction.
