Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Embodiment 1, a load industrial vehicle can be different types of vehicles such as fork truck, heap high car, letter sorting car, and this technical scheme uses heap high AGV as an example. As shown in fig. 1, the vehicle frame 1 includes two parts, a first vehicle frame 11 and a second vehicle frame 12. A driving wheel is arranged in the first frame 11, and the steering and starting and stopping of the driving wheel are controlled by a handle 7. On the second carriage 12, the mast 2 is mounted, and the mast 2 is connected to the forks 3 by means of a lifting device, such as a gear and rack transmission assembly. Further, a load wheel 4 is mounted on the second frame 12.

Unlike the prior art, the first frame 11 and the second frame 12 are designed independently and can move in the length direction of the frame 1. Such a movement causes the wheel base of the vehicle, i.e., the distance between the rear wheels (load wheels 4) and the front wheels (drive wheels) in the longitudinal direction of the vehicle body, to be changed.

Since the components above the first frame 11 section tend not to change under the influence of loads, the center of mass is fixed. And in the working environment, larger load goods need to be placed due to emergency, and at the moment, the wheel base of the vehicle is lengthened only by the sliding device 5, so that the requirement of larger load can be met. And when the narrow tunnel appears in the working environment, the vehicle does not need to be replaced, and only the sliding device 5 needs to be adjusted, so that the wheel base of the vehicle is shortened, the length of the whole vehicle body is naturally shortened, and the operation requirement of the temporary narrow tunnel can be met.

The particular manner of change of wheelbase, as shown in figures 2 and 3, requires the use of a slide 5 and a capture 6. The sliding device 5 includes a sliding rail 51 and a sliding block 52, in this embodiment, the sliding rail 51 is mounted on the first frame 11, and the sliding block 52 is mounted on the second frame 12, and in other embodiments, the reverse can be implemented. The slide rail 51 is formed in a half frame shape, and the slider 52 slides in the half frame shape. The sliding mode of sliding the sliding block of the sliding rail is not a frequent adjustment for adjusting the wheel base, and the stability and the supporting reliability in the sliding design are superior to the sliding smoothness. And the slide rail slider can provide suitable frictional force and better laminating degree to can realize the stability in the slip process.

Specifically, the half-frame-shaped slide rail 51 includes two lateral surfaces 511 extending in the horizontal direction and a vertical connecting surface 512 connecting the two lateral surfaces 511, and the vertical connecting surface 512 extends in the vertical direction. The slider 52 is a generally rectangular slider but is vertically sized to fit exactly within the track 51. I.e. the upper and lower surfaces of the slider 52 abut the two lateral surfaces 511. But in the horizontal direction, the size is designed to be slightly smaller, namely, the side surface of the sliding block 52 is not attached to the vertical connecting surface 512, and the sliding block and the vertical connecting surface are not contacted during the sliding process.

This is still designed for the sliding effect, and if the side surface of the slider 52 is fitted to the vertical connecting surface and there is no gap, the frictional force is too large, and the movement of the slider 52 is too laborious. The design mode of 'two paste one empty' of present case has guaranteed the appropriate smooth and easy degree of slip process promptly, has guaranteed the stability of support again, avoids too nimble.

When the sliding block 52 slides to a proper position and the wheel base is adjusted, the locking device 6 is needed to lock the sliding block 52 and the sliding rail 51, so as to fix the wheel base.

Specifically, the present disclosure adopts a dual-contact design, that is, the locking device 6 includes an upper contact and a side contact 61. The upper abutting member (not shown) extends in the vertical direction, and the transverse surface 511 passing through a high position from top to bottom abuts against the upper surface of the sliding block 52, so that the sliding block 52 is locked and fixed by static friction force. And the side interference piece 61 extends from the inside to the outside in the horizontal direction. As shown in fig. 3, the side contact piece 61 passes through the slider 52 and contacts the vertical connecting surface 512, and the slide rail 51 and the slider 52 are fixed by the static friction force. The side interference members 61 and the upper interference member may be fixed members, such as bolts, which are commonly used in the art.

In this embodiment, the number of the upper abutting members is not limited, and two or more side abutting members 61 are disposed on each of the sliders 52. This is because when the length of the slide block 52 and the slide rail 51 is long and only one side abutting piece 61 is provided, the two side abutting pieces can be turned over to a small extent by using the position of the side abutting piece 61 as a center, which affects the stability of the locking. When the number of the side contact pieces 61 is two or more, the two points define a line, and the retention stability of the slider 52 and the slide rail 51 in the vehicle body length direction is greatly improved.

Example 2: the difference from embodiment 1 is that a roller is added to the slide rail 51 of the slide device to increase the smoothness.

Example 3: the difference from embodiment 1 is the difference of the capture device 6. In this embodiment, a mode of resisting static friction force is not adopted, but a hole is formed in the slider, a plurality of matching holes matched with the slider are formed in the slide rail 51, and after a user moves the slider 52 to a proper position, a component such as a bolt is inserted into the corresponding matching hole and hole to complete locking connection of the slider and the slide rail.
