Background

The road roller is also called soil compactor, which is a kind of road repairing equipment. The road roller belongs to the field of road equipment in engineering machinery, is widely used for filling and compacting operation of large-scale engineering projects such as high-grade highways, railways, airport runways, dams, stadiums and the like, and can be used for rolling sandy, semi-viscous and viscous soil, roadbed stabilized soil and asphalt concrete pavement layers. The roller is suitable for various compaction operations under the action of the gravity of the machine, so that the compacted layer is permanently deformed and compacted. The road rollers are divided into two types, namely steel wheel type and tire type.

With the increase of the number and the variety of engineering construction projects, more requirements are put forward on the construction machine. In the construction of parks, town streets, underground garages, and the like, there are many limiting factors, for example, the height of the working machine is strictly limited. In order to avoid damages to operators in the sun, the operation machines such as road rollers, crushers and excavators are all provided with ceilings, and the total height of the ceilings and the machine body usually exceeds 2.5m, so that the requirements of some field construction cannot be met.

According to the utility model provides a second aspect embodiment provides a work machine, including fuselage 100 and according to the utility model discloses the ceiling device that the embodiment of first aspect provided, the bottom of the mount 10 of ceiling device is connected to fuselage 100. The work machine may be a road roller or other work machine with similar requirements.

Since the working machine is provided with the ceiling device, the working machine has all the technical effects of the ceiling device, and the details are not described herein.

Preferably, the bottom end of the fixed frame 10 is connected to the rear end of the top wall of the main body 100 in the length direction, a buffer member 110 is provided on the rear wall of the main body 100, and the rotating frame 20 touches the buffer member 110 when the ceiling device is in the closed state. The buffer member 110 may be a rubber member, a spring member, or other members with a buffering function. The buffer 110 is arranged, so that the rotating frame 20 can be contacted and limited with the buffer 110 when being overturned, and rigid collision between the rotating frame 20 and the machine body 100 is avoided.

More preferably, the curtain ceiling 30 is detachably coupled to the body 100 when the rotating bracket 20 touches the buffer 110. Specifically, optionally, a third limiting element is further included, and when the rotating frame 20 touches the buffer 110, the curtain ceiling 30 is detachably connected to the body 100 through the third limiting element, so as to prevent the ceiling device from shaking due to some reasons. When the second rotation axis 80 and the second limiting member 90 are disposed at the connection position between the overhanging part 70 and the second end of the turret 20, the second limiting member 90 and the third limiting member may be the same component, the second limiting member 90 is disposed on the overhanging part 70, the second limiting hole is disposed at the second end of the turret 20, the body 100 is provided with a third limiting hole, the second limiting member 90 is a limiting screw, both the second limiting hole and the third limiting hole are threaded holes, when the second limiting member 90 is inserted into the third limiting hole, the curtain-type ceiling 30 is detachably connected to the body 100, and when the second limiting member 90 is separated from the third limiting hole, the curtain-type ceiling 30 is disconnected from the body 100. It can be understood that, when the second limiting member 90 is released, the curtain ceiling 30 can be rotated relative to the rotating frame 20, the curtain ceiling 30 approaches the rotating frame 20, the occupied volume is small, the length of the machine body 100 is shortened, the second limiting member 90 can be locked again after the curtain ceiling 30 is folded, the curtain ceiling 30 is detachably connected with the machine body 100, and the stable state after the curtain ceiling 30 is folded is maintained. When the curtain ceiling 30 is far away from the fixed frame 10, the second limiting member 90 is locked, the curtain ceiling 30 and the second end of the rotating frame 20 are locked relatively, the curtain ceiling 30 cannot automatically rotate under the action of vibration or wind force, and a stable overhanging state can be maintained.

First, under construction conditions where the height is limited, when the curtain ceiling 30 is rotated from being far from the fixed frame 10 to being close to the fixed frame 10, the height of the ceiling device is lowered, and the construction machine can smoothly perform construction. When the height of the ceiling device is adjusted, the ceiling device does not need to be detached along the machine body 100, so that the construction efficiency is improved, and the application range is wide.

Secondly, the curtain type ceiling 30 can rotate along the rotating frame 20 and can be folded towards the position of the rotating frame 20, so that the whole length of the operation machine is shortened, and the construction operation is facilitated.

In summary, the ceiling device and the working machine provided by the embodiment of the present invention include a fixed frame 10, a rotating frame 20, and a curtain ceiling 30; curtain-type ceiling 30 is connected in rotating turret 20, and rotating turret 20 rotates with mount 10 to be connected for rotating turret 20 can rotate together with curtain-type ceiling 30 relative mount 10, and curtain-type ceiling 30 can switch between the state of stretching out and packing up, thereby will the utility model discloses a when the ceiling device is applied to the operating machinery, on the one hand because curtain-type ceiling 30 can switch between the state of stretching out and packing up, can reduce greatly the utility model discloses a ceiling device occupation space under the state of drawing in, on the other hand, rotating turret 20 can place the one side of mount 10 in together with curtain-type ceiling 30, makes the whole height of rotating turret 20 and curtain-type ceiling 30 all be not higher than mount 10, thereby obtains littleer whole height, better operation demand and the transportation demand that satisfies some construction scenes.

The above description is only for the preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
