[0001] This utility model relates to the field of engineering vehicle transportation, and in particular to a lowerable cab and engineering vehicle. Background Technology

[0002] There are many types of engineering vehicles, and they are widely used. At present, enterprises are increasingly expanding into the international market, and equipment exports will inevitably use containers. However, due to the height restrictions of containers, the driver's cab on the vehicle needs to be removed during transportation, occupying a separate container, which greatly increases transportation costs. Utility Model Content

[0003] The purpose of this application is to provide a lowerable cab and engineering vehicle, which raises or lowers the cab height by changing the connecting parts between the inner and outer floor plates, and uses a Z-shaped mounting plate to connect the inner and outer floor plates to adapt to the height of containers during transportation.

[0004] To solve the above technical problems, the following technical solution is adopted:

[0005] In a first aspect, the present invention provides a lowerable cab, comprising an outer floor plate, an inner floor plate, and a connecting component. The outer floor plate is disposed at the bottom of the cab shell, and driving equipment is mounted on the inner floor plate. The outer floor plate is connected to the inner floor plate through the connecting component, which includes a Z-shaped mounting plate and a fixing plate.

[0006] When the cab is being transported, the outer floor plate and the inner floor plate are connected by a Z-shaped mounting plate, thereby reducing the height of the cab shell. When the cab is being driven, the outer floor plate and the inner floor plate are connected by a fixing plate.

[0007] Optionally, at least two Z-shaped mounting plates are provided, with the two Z-shaped mounting plates respectively disposed on both sides of the inner bottom plate and connected to both sides of the outer bottom plate.

[0008] Optionally, the Z-shaped mounting plate includes a first plate, a second plate, and an intermediate plate connecting the first plate and the second plate. The inner bottom plate is connected to the first plate, the outer bottom plate is connected to the second plate, and the inner bottom plate is above the outer bottom plate.

[0009] Optionally, both the first plate and the second plate are provided with mounting holes, and the Z-shaped mounting plate is installed through the mounting holes and bolt assemblies.

[0010] Optionally, the driving device includes an instrument panel, a seat, a handbrake, and a control box, with the handbrake located on one side of the seat, the control box located on the other side of the seat, and the instrument panel located in front of the seat.

[0011] Optionally, the inner bottom plate is covered with a rubber floor.

[0015] Secondly, this utility model provides an engineering vehicle, including a vehicle body and the lowerable cab described in the first aspect, the lowerable cab being mounted on the vehicle body.

[0016] Compared with the prior art, the beneficial effects achieved by this application are as follows:

[0017] This utility model separates the inner floor plate for installing the driving equipment from the outer floor plate for installing the cab shell, and connects the inner and outer floor plates through different connecting parts, thereby changing the overall height of the cab. When using Z-shaped mounting plates for connection, the overall height of the cab can be reduced to meet the height requirements of containers. When using mounting plates for connection, the height of the cab can be increased to meet the requirements for driving. During transportation, only the outer floor plate needs to be disassembled and reinstalled. The structure is simple, the operation is convenient, and the management during transportation is convenient, which can save a lot of transportation costs.

[0018] The Z-shaped mounting plate of this utility model has a simple structure. In use, the inner bottom plate is connected to the first plate, and the outer bottom plate is connected to the second plate. The height of the inner bottom plate remains unchanged, while the height of the outer bottom plate is reduced, thereby reducing the height of the cab shell and thus reducing the overall height of the cab.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0027] like Figures 1-2 As shown, this embodiment provides a lowerable cab, including an outer floor plate 3, an inner floor plate 4, and connecting components. The outer floor plate 3 is disposed at the bottom of the cab shell 2, and driving equipment is installed on the inner floor plate 4. The outer floor plate 3 is connected to the inner floor plate 4 through the connecting components, and the connecting components include a Z-shaped mounting plate 11 and a fixing plate 10.

[0028] When the cab is being transported, the outer floor plate 3 and the inner floor plate 4 are connected by the Z-shaped mounting plate 11, thereby reducing the height of the cab shell 2. When the cab is being driven, the outer floor plate 3 and the inner floor plate 4 are connected by the fixing plate 10.

[0029] Since the cab needs space to accommodate the driver, the cab shell 2 is relatively high. Therefore, in this embodiment, the height of the container can be met during cab transportation. Furthermore, during cab transportation, there is no need for space to accommodate the driver in the cab. The inner bottom plate 4 and the outer bottom plate 3 can be connected by a Z-shaped mounting plate 11. At this time, the outer bottom plate 3 is located below the inner bottom plate 4, and the height of the cab shell 2 is reduced, thereby reducing the overall height of the cab. Example 2

[0030] This embodiment provides a lowerable cab based on Embodiment 1, but differs from Embodiment 1 in that:

[0031] like Figure 2 , Figure 4 As shown, there are four Z-shaped mounting plates 11. The four Z-shaped mounting plates 11 are arranged on both sides of the inner bottom plate 4 and connected to both sides of the outer bottom plate 3. The upper and lower ends of the Z-shaped mounting plates 11 are connected to the inner bottom plate 4 and the outer bottom plate 3 respectively. The outer bottom plate 3 is installed at the lower end, which can both install the outer bottom plate 3 and the cab shell 2 on the inner bottom plate 4 and lower the height of the cab shell 2 on the outer bottom plate 3.

[0032] The Z-shaped mounting plate 11 includes a first plate, a second plate, and an intermediate plate connecting the first plate and the second plate. The inner bottom plate 4 is connected to the first plate, and the outer bottom plate 3 is connected to the second plate.

[0033] In this embodiment, the first plate is located above the second plate, and the first and second plates are parallel to each other, so that the outer bottom plate 3 is located below the inner bottom plate 4. Both the first and second plates are provided with multiple mounting holes. By using bolt assemblies to engage with the mounting holes, the Z-shaped mounting plate 11 is installed with the inner bottom plate 4 and the outer bottom plate 3. Without changing the installation position and relationship of the inner bottom plate 4, the outer bottom plate 3 is connected to the second plate, thereby reducing the height of the cab shell 2 and thus reducing the overall height of the cab.

[0034] The descendable cab provided in this embodiment separates the inner floor plate 4 for installing the driving equipment and the outer floor plate 3 for installing the cab shell 2. During transportation, it is not necessary to completely remove the cab from the vehicle body 1. Only the outer floor plate 3 with the cab shell 2 needs to be removed from the inner floor plate 4. The inner floor plate 4 and the outer floor plate 3 are then connected using a Z-shaped mounting plate 11, which lowers the overall height of the cab. The cab can be installed on the vehicle body 1 for transportation without separate loading and transportation, reducing management during transportation and facilitating disassembly during loading and unloading. The Z-shaped mounting plate 11 has a simple structure and low cost.

[0035] like Figure 1 , Figure 3 , Figure 4 As shown, when driving in the cab, the Z-shaped mounting plate 11 is replaced with the fixing plate 10, and the inner floor plate 4 and the outer floor plate 3 are installed together. At this time, the inner floor plate 4 and the outer floor plate 3 are at the same horizontal height, the height of the cab shell 2 is restored to its original height, and the driver can enter the interior space.

[0036] In some embodiments, the driving equipment includes an instrument panel 14, a seat 15, a handbrake 17, and a control box 16. The seat 15 is located in the center of the inner floor 4, and the instrument panel 14 is located in front of the seat 15. A steering wheel is mounted on the instrument panel 14. A handbrake is located on one side of the seat 15, and a control box 16 is located on the other side.

[0037] The inner floor plate 4 is also equipped with a rear cover plate 7, which is located behind the seat. Both the rear cover plate 7 and the cab shell 2 have several bolt holes. The rear cover plate 7 is connected to the cab shell 2 by means of bolt holes and bolts, so as to enhance the connection between the inner floor plate 4 and the cab shell 2. When the outer floor plate 3 is removed, the rear cover plate 7 is removed and replaced with the Z-shaped mounting plate 11. Then, the rear cover plate 7 is installed with the bolt holes at a higher position on the cab shell 2 to achieve stable installation of the cab shell 2 and avoid collision between the cab shell 2 and other components during transportation.

[0038] A rubber floor 8 is laid on the upper surface of the inner floor plate 4. The rubber floor 8 is installed on the inner floor plate 4 by bolts. Holes are opened on the rubber floor 8 for installing the driving equipment on the inner floor plate 4.

[0039] An operating platform support plate 12 is provided at the bottom of the inner base plate 4. Shock absorbers 5 are installed at both ends of the operating platform support plate 12. The shock absorbers 5 are connected to the shock absorber blocks 6. The shock absorber blocks 6 are provided with countersunk holes. The shock absorbers 5 are installed at the bottom of the inner base plate 4 through the countersunk holes and the dome seal 13. The dome seal 13 is inserted into the countersunk holes from the openings on the surface of the inner base plate 4.

[0040] An adjusting washer 9 is also provided between the shock absorber 5 and the shock absorber block 6. The shock absorber 5, the adjusting washer 9 and the shock absorber block 6 are stacked in sequence from bottom to top and connected together by bolts. The shock absorber block 6 is connected to the inner floor plate 4, and the shock absorber 5 is connected to the control panel support plate 12, which plays a role in shock absorption and support for the driving equipment on the inner floor plate 4.

[0041] There are two control panel support plates 12, which are respectively set on the two sides of the base plate. The control panel support plates 12 are installed on the vehicle body 1, thereby enabling the driver's cab to be installed on the vehicle body 1 for use.

[0042] During transportation, the cab shell 2 and the outer floor plate 3 are connected together. The fixing plate 10 between the outer floor plate 3 and the inner floor plate 4 is removed, and the rear cover plate 7 is removed from the inner wall of the cab shell 2. The connection between the inner floor plate 4 and the outer floor plate 3 is replaced with a Z-shaped mounting plate 11. The position of the inner floor plate 4 on the vehicle body 1 remains unchanged, and it is connected to the first plate of the Z-shaped mounting plate 11. The height of the outer floor plate 3 and the cab shell 2 is reduced, and they are connected to the second plate of the Z-shaped mounting plate 11. The rear cover plate 7 is then reconnected to the bolt holes at the high point of the cab shell 2 to prevent the cab from shaking. The overall cab height is reduced to adapt to the height of the container during transportation. The cab does not need to be removed from the vehicle body; only the cab shell 2 needs to be removed and the connecting parts replaced to achieve the reduction in cab height. After the transport arrives at the destination, the Z-type mounting plate 11 is replaced with the fixed plate 10. The inner bottom plate 4 and the outer bottom plate 3 are on the same horizontal plane. The cab shell 2 is restored to its original height. The cab can be driven and used by the driver. The vehicle body 1 and the cab are in a container, which can also reduce logistics management and make transportation more convenient and faster. Example 3

[0043] This embodiment provides an engineering vehicle based on Embodiment 1 or Embodiment 2, including a vehicle body 1. The vehicle body 1 is equipped with a lowerable cab provided in Embodiment 1 or Embodiment 2. The engineering vehicle can be a road roller, excavator, bulldozer, etc. The cab of the engineering vehicle is usually higher than the vehicle body 1, requiring a higher field of vision to complete the operation. During transportation, the cab and vehicle body 1 are usually separately packaged in a container, which not only requires a lot of manpower and resources for the disassembly and assembly of the engineering vehicle, but also increases the workload of logistics management during transportation. The cab of the engineering vehicle in this embodiment is lowerable. It is only necessary to remove the cab shell 2, replace the connecting parts, and re-fix it to the vehicle. The structure is simple, the operation is convenient, and the logistics management cost can be reduced.
