Description

TECHNICAL FIELD

[0001] The application belongs to the field of auxiliary installation devices, and particularly relates to a support device for a cab. BACKGROUND

[0002] The existing vehicle has a chassis and a cab installed on the chassis. In the production stage, the cab is hoisted and then placed on the chassis, and then the cab is fixed. Therefore, the cab needs to be transported from the storage position to the workshop, and then the cab is transported by hoisting in the workshop, which leads to a too long hoisting and transporting path. In the process of hoisting and transporting the cab, in order to avoid the cab from colliding with the remaining devices in the workshop, a avoiding space needs to be reserved, which affects the arrangement of the devices in the workshop, and a large amount of space needs to be provided in the workshop to serve the installation operation of the cab.

[0003] The existing cab needs to install an accessory part at the bottom of the cab before being installed on the chassis. Therefore, the existing technology can only install the accessory part at the bottom of the cab in the process of hoisting the cab, and the cab is in a suspended state. In the installation process, the operator needs to pay attention to the state of the cab at all times to prevent the cab from shaking due to large stress during the installation process, which leads to a complicated installation process of the accessory part and reduces the installation efficiency of the accessory part.

[0004] The existing cab transporting device places the cab on the transporting device, and then moves the transporting device to realize the transportation of the cab in the workshop. However, the installation of the accessory part at the bottom of the cab still needs to hoist the cab, and the cab is in a suspended state. The operator needs to perform the installation operation under the cab, and the installation process is still complicated and the installation efficiency is low. CONTENT OF THE INVENTION

[0005] The application provides a support device for a cab to solve the technical problem that the operator needs to install an accessory part under the hoisted cab, and the cab shakes and is unstable, which is not convenient for the installation operation in the prior art.

[0006] The technical scheme adopted by the application is as follows:

[0007] A support device for a cab, the support device comprising a support base and a plurality of support frames spaced apart along a predetermined direction on the support base, the cab being placed on the support device, the support frames abutting against the cab, and the support frames extending towards a side away from the support base to form an operation space below the cab.

[0008] The support device in the application further comprises the following additional technical features:

[0009] The support base comprises an upper positioning frame and a lower positioning frame, and a connecting rod connecting the upper positioning frame and the lower positioning frame, the upper positioning frame is connected with the support frame, and the upper positioning frame is provided with a receiving area between two adjacent support frames, the receiving area extends towards the lower positioning frame, and the receiving area communicates with the operation space.

[0010] The lower positioning frame is also provided with the receiving area, and the receiving area of the upper positioning frame is arranged opposite to the receiving area of the lower positioning frame.

[0011] The support frame is provided with at least two support frames, and the two support frames are arranged opposite to each other along the preset direction, the support frame abutting against the rear of the bottom of the cab is a first support frame, and the support frame abutting against the front of the bottom of the cab is a second support frame, and the first support frame is higher than the second support frame.

[0012] The first support frame and the cab are provided with a positioning convex column and a positioning hole matched with the positioning convex column.

[0013] The support frame comprises a plurality of vertical support rods connected with the support base and a support cross rod, one end of the vertical support rod is connected with the support base, the other end extends towards a side away from the support base and is connected with the support cross rod, and the support cross rod abuts against the cab.

[0014] The support cross rod has an abutting surface abutting against the cab, and the support device is provided with a buffer on the abutting surface.

[0015] The support device is also provided with a plurality of auxiliary support rods, one end of the auxiliary support rod is connected with the support base, and the other end is connected with the vertical support rod.

[0016] The support device is provided with a plurality of guide wheels along the outer edge of the bottom of the support base in a circumferential direction, and the support device can carry the cab to move.

[0017] The support device is also provided with a locking member on the guide wheel, and the locking member locks the guide wheel to fix the support device at a set position.

[0018] Due to the above technical scheme, the application has the following beneficial effects:

[0019] 1. This application improves the load-bearing capacity of the support device by arranging multiple support frames at intervals along a predetermined direction on the support. The multiple support frames also distribute the weight of the cab, enhancing its stability during assembly. By extending the support frames away from the support, an operating space is created below the cab for the operator, allowing them to assemble auxiliary components. This facilitates assembly work and improves the efficiency of auxiliary component assembly.

[0020] 2. As a preferred embodiment of this application, by setting up an upper positioning frame, a lower positioning frame, and a connecting rod, the upper and lower positioning frames are connected by the connecting rod to form a stable frame structure. The support frame can better distribute the external forces it bears, avoiding instability such as swaying and tilting. This ensures that the support device maintains a reliable and stable state under the action of forces in different directions, facilitating the placement and removal of the cab from the support device. Simultaneously, the frame structure is lightweight, reducing production costs. By providing a receiving area between two adjacent support frames, extending towards the lower positioning frame and connecting the receiving area to the operating space, the operating space is extended through the receiving area, allowing operators to operate more conveniently and improving work efficiency.

[0021] Furthermore, by having a receiving area on the lower positioning frame, and the receiving areas of the upper positioning frame being set opposite to those of the lower positioning frame, the operating space is further extended. Operators can make reasonable use of the receiving area and operating space to adjust their working posture and assembly actions, making the working process more comfortable and improving work efficiency.

[0022] 3. In a preferred embodiment of this application, two support frames are arranged opposite each other along a preset direction. The two support frames can provide stable support force, keeping the cab in a fixed position. The bottom of the cab is set with an inclined bottom surface, and the distance between the front of the bottom of the cab and the ground is less than the distance between the rear of the bottom of the cab and the ground. By setting the first support frame higher than the second support frame, the posture of the cab placed on the support device is close to that of the cab placed on the chassis, which facilitates the positioning of auxiliary components installed on the cab and optimizes the installation process of auxiliary components.

[0023] Furthermore, by setting positioning protrusions and positioning holes, the cab can be accurately placed in the set position of the support device through the cooperation of the positioning protrusions and positioning holes, providing precise positioning for the cab placement and optimizing the process of placing the cab in the support device.

[0024] 4. As a preferred embodiment of this application, by setting a support crossbar to abut against the cab, the support crossbar increases the contact area between the support device and the cab, thereby improving the support capacity of the support frame. By setting multiple vertical support rods, the support crossbar disperses the weight of the cab through the multiple vertical support rods, enabling the support device to stably support the cab and improving the stability of the cab during the assembly of auxiliary parts, placement, and removal from the support device.

[0025] Furthermore, by setting up a buffer, hard contact between the cab and the support crossbar is avoided, preventing collision damage between the cab and the support crossbar. During the contact between the cab and the support crossbar, the buffer can absorb the impact force of the cab, allowing the cab to be placed stably on the support device, thus improving the stability of the support device in supporting the cab.

[0026] In one embodiment, by setting multiple auxiliary support members, one end of each auxiliary support member is connected to a support, and the other end is connected to a vertical support rod, thereby improving the supporting capacity of the vertical support rod and enhancing the overall structural strength of the support device.

[0027] 5. As a preferred embodiment of this application, by setting multiple guide wheels, the support device can carry the cab to move, thereby increasing the scenarios in which the support device can be applied. The support device can reach the storage location of the cab and play the role of transporting the cab. Alternatively, the support device can be transported to the vicinity of the cab after the cab has been transported to a designated location to assemble the auxiliary components of the cab. Then, the assembled cab can be transported to the vicinity of the chassis through the support device, thereby improving the mobility of the cab and the applicability of the support device.

[0028] Furthermore, by incorporating locking components, the guide wheels are locked to fix the support device in a designated position, improving its stability. When the support device is placed in or removed from the cab, the locking components lock the guide wheels, ensuring the support device can stably support the cab. This also facilitates the storage of the support device and prevents it from moving due to external influences. Attached Figure Description
