Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction equipment, in particular to a cab for an engineering vehicle. Background Art

[0002] In the process of tunnel excavation, various engineering vehicles are usually used. Some tunnels have small cross-sections, but the turning radius of the construction vehicles is large, which makes it impossible to turn around. The working device is at the rear end of the vehicle, so the vehicle must be reversed into the tunnel. During the reversing process, the driver needs to sit sideways, look to the back, and operate the vehicle with the other hand. This is not only inconvenient to drive, but also dangerous.

[0003] The existing cab, such as the lifting cab disclosed in the publication (announcement) number: CN217320550U, is located on the outside of the supporting end of the vehicle body, which will increase the length of the vehicle body to a certain extent and increase the difficulty of turning the vehicle. At the same time, the cab of the device is connected to the vehicle body through the cab lifting cylinder. When the operator sits in the cab to operate, there will be a certain vibration. Since only one side of the cab is connected to the vehicle body and the whole is in a suspended state, the overall weight of the cab is completely borne by the cab lifting cylinder, and looseness will occur after working for a long time. Utility Model Content

[0004] In order to overcome the deficiencies in the background technology, the utility model discloses a cab for an engineering vehicle. The utility model shares the overall weight of the driver through the main beam on the rear side of the vehicle body, avoiding that the driver's weight and the force generated during operation are all borne by the cab, and at the same time can reduce the overall volume of the cab and reduce the turning radius during turning. The cab is located in the rear end frame of the vehicle body, avoiding that the separately added cab lengthens the overall length of the vehicle body, and at the same time facilitates the operator to reverse the vehicle.

[0005] In order to achieve the purpose of the utility model, the utility model adopts the following technical solutions:

[0006] A cab for an engineering vehicle comprises a vehicle body, wherein the cab is installed at the middle position of the rear end of the vehicle body.

[0007] The cab includes a cab body, a seat, a telescopic rod, a cab roof and a lifting cylinder. The cab body and the seat are installed on the vehicle body and fixedly connected, and two telescopic rods are fixedly connected to one side of the cab body, the telescopic end of the telescopic rod is fixedly connected to the cab roof, and a lifting cylinder is fixedly connected to the cab roof, the other end of the lifting cylinder is fixedly connected to the cab body, and the lifting cylinder is located between the two telescopic rods.

[0008] The cab body is located between the hydraulic support end at the rear side of the vehicle body and the rear side beam and is fixedly connected.

[0009] The seat is located on the beam at the rear side of the vehicle body, and the position of the seat corresponds to the position of the cab body.

[0010] The cab body and the seat are both located in the middle of the hydraulic support end at the rear side of the vehicle body and the rear side beam.

[0011] The position of the cab roof corresponds to the positions of the cab body and the seat.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects:

[0013] The utility model discloses a cab for an engineering vehicle, which shares the overall weight of the driver through the main beam at the rear side of the vehicle body, so that the driver's weight and the force generated during operation are not all borne by the cab, and the overall volume of the cab can be reduced, and the turning radius can be reduced during turning. The cab is located in the rear end frame of the vehicle body, so that the overall length of the vehicle body is not lengthened by a separately added cab, and it is convenient for the operator to reverse the vehicle.

[0017] The present invention can be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0018] Combined with Figure 1~2 The driving cab for an engineering vehicle comprises a vehicle body 1 , and a driving cab 2 is installed at the middle position of the rear end of the vehicle body 1 .

[0019] The cab 2 includes a cab body 201, a seat 202, a telescopic rod 203, a cab roof 204 and a lifting cylinder 205. The cab body 201 and the seat 202 are both mounted on the vehicle body 1 and fixedly connected, and two telescopic rods 203 are fixedly connected to one side of the cab body 201, the telescopic ends of the telescopic rods 203 are fixedly connected to the cab roof 204, and a lifting cylinder 205 is fixedly connected to the cab roof 204, and the other end of the lifting cylinder 205 is fixedly connected to the cab body 201, and the lifting cylinder 205 is located between the two telescopic rods 203.

[0020] The cab body 201 is located between the rear hydraulic support end of the vehicle body 1 and the rear beam and is fixedly connected to avoid increasing the overall length of the vehicle body 1.

[0021] The seat 202 is located on the beam at the rear side of the vehicle body 1, and the position of the seat 202 corresponds to the position of the cab body 201. The position of the seat 202 is fixed by the beam at the rear side of the vehicle body 1, and the driver's own weight is shared by the beam at the rear side of the vehicle body 1.
