Description

Technical Field

[0001] The present application relates to the field of engineering vehicles, and particularly to a cab bracket device. Background Art

[0002] In wetland areas, due to the high water content of the soil and soft geology, the low ground bearing capacity causes construction vehicles to sink. As a result, the height of the cab decreases, affecting the operator's line of sight, and even causing the cab to sink into the mud, which greatly hinders wetland construction operations. The traditional solution is to lay road plates, steel plates, pipe rows, etc. in the work area. Although it has a certain effect, there are problems such as a large amount of auxiliary work and high costs, and it is not suitable for large-scale applications. In wetlands and other low-bearing capacity grounds, it is necessary to increase the height of the cab to meet the line-of-sight requirements during operation. Summary of the Utility Model

[0024] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way restrictive of the present application and its application or use.

[0025] Embodiment 1

[0026] As Figures 1-4 shown, this embodiment provides a cab bracket device, including a bracket 1, a vehicle frame 4 and an oil cylinder 3. A cab is installed on the bracket 1. One end of the bracket 1 is welded to one surface of the connecting member 2. The connecting member 2 is connected to the guide rail 401 on the vehicle frame 4. The movable end of the oil cylinder 3 is fixed to the connecting member 2, and the fixed end of the oil cylinder 3 is installed on the vehicle frame 4. By the telescopic movement of the oil cylinder 3, the connecting member 2 moves up and down on the vehicle frame 4. Two oil cylinders 3 are symmetrically arranged on the vehicle frame 4 and connected to the connecting member 2. The vehicle frame 4 is installed on the vehicle body. By controlling the telescopic movement of the oil cylinder 3, the cab on the bracket 1 is driven to move up and down, and the height of the cab relative to the vehicle body is adjusted to meet the line-of-sight requirements during operation.

[0027] On the side of the connecting member 2, a first limit pin 205 and a second limit pin 206 are provided. The first limit pin 205 is arranged at a position on the upper side of the side of the connecting member 2 to limit the first position of the connecting member 2 on the vehicle frame 4. The first position is the highest point position of the connecting member 2 on the guide rail 401, to prevent the connecting member 2 from moving upward and disengaging from the guide rail 401. The second limit pin 206 is arranged at a position on the lower side of the side of the connecting member 2 to limit the second position of the connecting member 2 on the vehicle frame 4. The second position is the lowest point position of the connecting member 2 on the guide rail 401, to prevent the connecting member 2 from moving downward and disengaging from the guide rail 401. By providing the first limit pin 205 and the second limit pin 206, it is ensured that the cab on the bracket 1 moves up and down within a safe range, and it can also prevent the cab from losing balance on the entire vehicle due to being too high or too low in position.

[0028] Embodiment 2

[0029] As Figures 1-5 shown, this embodiment provides a technical solution based on Embodiment 1. The difference from Embodiment 1 is that the connecting member 2 is a box structure with upper and lower openings, including a first surface 201, a second surface 202 and two side surfaces. The side surfaces include a first side plate 203 and a second side plate 204. One end of the first side plate 203 is welded to the first surface 201, and the other end is welded to the second surface 202. One end of the second side plate 204 is welded to the first surface 201. A reinforcing rib 208 is provided between the first side plate 203 and the first surface 201. Extended regions extend outward from both sides of the first surface 201, and reinforcing ribs are provided between the extended regions and the second side plate 204. The reinforcing ribs are used to strengthen the side structure of the connecting member 2.

[0030] The first side plate 203 and the second side plate 204 are connected together by the first limit pin 205 and the second limit pin 206. At least one fixing pin 207 is provided between the first limit pin 205 and the second limit pin 206 on the side surface. There is a gap between the first side plate 203 and the second side plate 204. Two guide rails 401 are arranged at intervals. The guide rails 401 are respectively arranged in the gaps on the two side surfaces. A notch 402 is further provided on the guide rail 401. The first limit pin 205, the second limit pin 206 and the fixing pin 207 are arranged through the notch 402 to connect the connecting member 2 to the guide rail 401.

[0031] Guide rail bottom plates 404 are provided at the lower ends of the two guide rails 401 to prevent the connecting member 2 from moving downward and disengaging from the guide rail 401.

[0032] Bolts 209 are also provided on the first side plate 203 and the second side plate 204. The bolts 209 can adjust the size of the gap to adjust a suitable gap size, which can not only adapt to the movement of the connecting member 2 on the guide rail 401, but also ensure that the connecting member 2 does not shake left and right.

[0033] An ear plate 210 is provided at the lower end of the first surface 201. The ear plate 210 is connected to the movable end of the oil cylinder 3. An ear plate 403 is provided above the guide rail 401 of the vehicle frame. The ear plate 403 is connected to the fixed end of the oil cylinder 3. Through the telescopic movement of the movable end of the oil cylinder 3, the connecting member 2 moves on the guide rail 401, thereby realizing the up and down movement of the bracket 1.

[0034] The bracket 1 includes two enclosing plates 101 and a plurality of intermediate beams 102. The two ends of the intermediate beam 102 are respectively welded to the two enclosing plates 101. A reinforcing rib 103 is also provided at one end of the bracket 1 where it is installed with the connecting member 2. The two ends of the reinforcing rib 103 are respectively welded to the bracket 1 and the connecting member 2.

[0035] The structure of this application is simple. By controlling the telescopic movement of the oil cylinder through the control system, the operator's cab on the bracket is driven to move up and down. There are two oil cylinders and guide rails symmetrically arranged respectively to ensure the stability during the movement of the operator's cab. The gap on the side of the connecting member is adjusted by bolts to connect with the guide rail and ensure that it will not shake left and right during use. The requirement for the accuracy of the vehicle frame is low, which is convenient for processing.

[0038] The above are only the preferred embodiments of this application. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of this application, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of this application.
