Technical Field

[0001] This utility model belongs to the technical field of driver's cabs, and particularly relates to a welded frame assembly for a driver's cab. Background Technology

[0002] A patent entitled "A Wide-Body Fully Welded Frame Mine Car Cab" is disclosed in the existing Chinese patent database. The application number is 202322919499.3, and the application date is 2023-10-31. The wide-body fully welded frame mine car cab includes a main frame, which includes side frame plates, a front frame plate, and a top plate. The side frame plates are internally hinged with opening and closing doors. The bottom of the front frame plate is provided with a heat dissipation plate groove. The rear side of the main frame is provided with a mudguard. The top of the front frame plate is provided with a connecting plate. The top of the mudguard is provided with a connecting seat. The bottom of the heat dissipation plate groove is provided with a frame bottom edge. This utility model features a main frame, a heat dissipation plate groove, and connectors. The main frame is formed by welding side frame plates, front frame plates, and top plates together to create the main frame of the cab. The overall structure is stable and low in cost. The mine car body or mine car cargo can be positioned and installed on the outside of the connecting seat, and then locked to the main frame by the connectors. The positioning clamps of the connectors can clamp the outer wall of the cargo compartment and then be locked by a locking rod, increasing the support points of the connection and improving stability.

[0003] The cab is frequently subjected to bumps and vibrations. A cab with an unstable structure is prone to damage or loss of screws at the connection points, which makes it difficult to ensure driving safety. Therefore, this paper aims to propose a welded frame assembly for the cab. Through the whole-body welded structure, it can reduce costs and ensure its own strength. Utility Model Content

In order to improve its shortcomings, this utility model provides a welded frame assembly for the cab.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A welded frame assembly for a driver's cab includes two sets of spaced-apart side frame bodies connected by several crossbars. A top plate is provided at the upper end of the side frame body, and an inclined plate for installing a windshield is provided above the front end of the side frame body. An opening is provided in the middle of the inclined plate. A front cover is provided below the front end of the side frame bodies. Opening and closing doors are hinged to both sides of the side frame bodies, and an auxiliary support frame extends from the rear end of the side frame bodies.

[0007] Compared with the prior art, the beneficial effects of this utility model are: due to the coordinated arrangement of the side frame, top plate, inclined plate and auxiliary support frame, the entire cab is welded together from several parts and the connection support points are set inside the side frame, which improves the stability of the main frame after welding. The cab frame assembly has high strength after welding, is suitable for industrial production and has strong practicality.

[0008] As a preferred embodiment, the side frame includes an upper rod and a lower rod.

[0017] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-2The diagram shows a welded frame assembly for a cab, comprising two sets of spaced-apart side frame bodies 1 connected by several crossbars. A top plate 2 is located at the upper end of each side frame body 1. A ramp 3 for mounting a windshield is located above the front end of each side frame body 1, with an opening 4 in the middle of the ramp 3. A front hood 5 is located below the front end of each side frame body 1. Hinged doors 6 are attached to both sides of each side frame body 1. An auxiliary support frame 7 extends from the rear end of each side frame body 1. The side frame bodies 1, top plate 2, ramp 3, and auxiliary support frame 7 are welded together, resulting in high strength and preventing damage or detachment of screws at connection points in a cab with a weak structure, especially after frequent bumps.

[0019] Specifically, the side frame 1 includes an upper rod 101 and a lower rod 102. The rear free ends of the upper rod 101 and the lower rod 102 are welded together via a long vertical rod 103. A long diagonal rod 104 is welded to the front free end of the upper rod 101, and a short vertical rod 105 is welded to the free end of the long diagonal rod 104. The short vertical rod 105 is welded to the front free end of the lower rod 102. An auxiliary support vertical rod 106 is also provided between the middle of the long diagonal rod 104 and the lower rod 102. The auxiliary support vertical rod 106 is provided inside the annular closed side frame 1, so that there are connecting support points inside the side frame 1, which improves the support and stability of the main frame after welding.

[0020] Specifically, the auxiliary support frame 7 includes an L-shaped rod 701 welded to the rear end of the side frame 1. The upper rod 101 of the side frame 1 extends to the free end of the vertical section of the L-shaped rod 701 and is welded to it. The free end of the horizontal section of the L-shaped rod 701 is welded to the long vertical rod 103 of the side frame 1. A short diagonal rod 702 is welded to the rear free end of the lower rod 102 of the side frame 1. The free end of the short diagonal rod 702 is welded to the lower surface of the horizontal section of the L-shaped rod 701. The auxiliary support frame 7 extends the rear end space of the original side frame 1, and the cooperation between the short diagonal rod 702 and the L-shaped rod 701 ensures support for the top of the side frame 1 after the extension, thus ensuring the stability of the entire welded frame.

[0021] Specifically, a pre-reserved ventilation hole 8 is provided at the upper end of the top plate 2. A hinge 9 is installed on the side frame 1, and the other end of the hinge 9 is connected to the door 6.

[0022] Therefore, due to the coordinated arrangement of the side frame 1, top plate 2, inclined plate 3 and auxiliary support frame 7, the entire cab is welded together from several parts, and the side frame 1 is equipped with connecting support points, which improves the stability of the main frame after welding.

[0023] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
