Detailed Description

The following examples of the present utility model are described in detail, and are given by way of illustration of the present utility model, but the scope of the present utility model is not limited to the following examples.

As shown in fig. 1-4, a lightweight cab enclosure for easy installation, comprising: a main housing 1, a base 2 and a connecting structure 3.

The main shell 1 comprises a front baffle, two side coamings and a rear backboard 4, and all boards are welded and fixed. The rear backboard 4 is close to the rear carriage, and is made of aluminum alloy, so that the weight of the whole main shell 1 is reduced. Meanwhile, two sides of the lower end of the rear backboard 4 are provided with first limiting holes 5.

The bottoms of the coamings at the two sides are provided with roller type slide rails.

The base 2 is provided with a sliding groove 13 which is matched with the sliding rail at the opposite position. The rear side of the base 2 is provided with a vertical plate which is made of aluminum alloy, and a first mounting hole 6 is formed in the vertical plate at the position opposite to the first limiting hole 5.

The base 2 is also provided with a fourth mounting hole, and the position of the fourth mounting hole is positioned at the front side of the base 2 and is used for connecting a frame.

The cab is integrally mounted by means of an "L" shaped plate 11, pins 10 and fittings, in this embodiment stop plates and flanges 12.

First, the vertical part of the L-shaped plate 11 is provided with a second mounting hole 8, and the first mounting hole 6 and the first limiting hole 5 are sleeved with a flange 12. The pin shaft 10 passes through the second mounting hole 8, the flange 12 in the first limiting hole 5 and the flange 12 in the first mounting hole 6 to connect the main shell 1 and the base 2. It is noted that, in order to improve the driving feeling of the driver and the shock absorbing capacity of the cab, the pin shaft 10 between the first limiting hole 5 and the first mounting hole 6 is sleeved with a cylindrical rubber ring. In order to achieve better effect, the butadiene rubber is adopted in the embodiment, and has the advantages of good wear resistance and rebound resilience. After the pin shaft 10 is installed, the fixing is not further reinforced, and limiting plates are arranged at two ends. The limiting plate is provided with a threaded hole, the vertical parts of the vertical plate and the L-shaped plate 11 are provided with hollow threaded seats corresponding to the threaded holes, and after the two ends of the pin shaft 10 respectively pass through the two threaded seats, the limiting plate is screwed tightly, so that the pin shaft 10 is prevented from moving horizontally.

And secondly, the base 2 is provided with a second limiting hole 7 and a third mounting hole 9 formed in the horizontal part of the L-shaped plate 11, and the connection between the main shell 1 and the vertical plate can be reinforced again through nuts and bolts.

During installation, the base is fixedly connected with the frame, then a section of slope slide rail is connected with the slide rail on the base, the main shell of the cab can be pushed into the installation point, and then the main shell can be connected with the base by utilizing simple assembly parts such as a pin shaft, a screw and the like.
