Detailed Implementation

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] Embodiments of this utility model: such as Figures 1-11 As shown, a forklift high-level cab structure includes a frame 1 and a top guard frame body 2. Two rear support legs 3 on the top guard frame body 2 are respectively connected to the frame 1 through support frames 4. Two front support legs 5 on the top guard frame body 2 are fixedly connected to the front leg fixing points on the frame 1. The front support legs 5 and the support frames 4 located on the same side are connected by a support beam assembly 6.

[0030] The frame 1 of this utility model adopts the existing forklift frame technology. The main body 2 of the overhead guard only increases the length of the two front support legs 5, while the slope of the two front support legs 5 remains unchanged from the existing technology. The rear of the main body 2 of the overhead guard is supported and fixed by two support frames 4. By lengthening the front support legs 5 and setting two support frames 4, the overall height of the cab is increased to meet the customer's need for a high-position cab. After the cab is raised, in order to ensure the structural strength and stability of the cab, support beam assemblies 6 are set on both the left and right sides. The setting of two support beam assemblies 6 improves the structural strength and stability of the raised cab.

[0031] Specifically, the two supporting crossbeam assemblies 6 are arranged symmetrically. Both supporting crossbeam assemblies 6 are formed by sequentially welding and fixing the first steel pipe 7, the second steel pipe 8, the third steel pipe 9, the fourth steel pipe 10, and the fifth steel pipe 11. The two first steel pipes 7 are parallel to each other, the two third steel pipes 9 are parallel to each other, the two fifth steel pipes 11 are parallel to each other, the two second steel pipes 8 are arranged in a figure-eight shape with the front end farther than the rear end, and the two fourth steel pipes 10 are arranged in a figure-eight shape with the front end closer than the rear end.

[0032] To ensure the structural strength of the two supporting crossbeam assemblies 6, the first steel pipe 7, the second steel pipe 8, the third steel pipe 9, the fourth steel pipe 10, and the fifth steel pipe 11 are all rectangular steel pipes with a specification of 100mm*50mm. Their specific lengths are adjusted according to the actual dimensions of the forklift cab.

[0033] The two support beam assemblies 6 together form the support frame of the forklift cab. Since both support beam assemblies 6 are integrated support beams, they can effectively ensure the structural strength of the cab after it is raised and ensure the stability of the support.

[0034] To facilitate the installation of the upper panels, it is preferable to have two rivet nuts on the outer walls of the support frame 4, the second steel pipe 8, the third steel pipe 9, and the fourth steel pipe 10, respectively. The first upper panel 16 is installed on the second steel pipe 8, the second upper panel 17 on the third steel pipe 9, and the third upper panel 18 on the fourth steel pipe 10. The rivet nuts allow for quick installation and removal of the first upper panel 16, the second upper panel 17, and the third upper panel 18. A rivet nut is provided on the outer wall of the fifth steel pipe 11. The front end of the fourth upper panel 19 is connected to the fifth steel pipe 11 by a bolt, and the rear end is connected to the support frame 4 by two bolts. The lower ends of the first upper panel 16, the second upper panel 17, and the third upper panel 18 are fixedly connected to the frame 1 by bolts. The mounting hole positions on the frame 1 do not need to be modified and can remain consistent with existing technology.

[0035] The design of the first upper panel 16, the second upper panel 17, the third upper panel 18, and the fourth upper panel 19 solves the side closure problem at the raised cab position, improving the overall aesthetics of the vehicle. When the forklift needs repair or maintenance, only the corresponding upper panel needs to be removed, without needing to disassemble the support beam assembly 6, greatly improving repair and maintenance efficiency.

[0036] It should be noted that lower panels 14 are fixed on both the left and right sides of the frame 1, and foot pedal avoidance parts 15 are formed at the front end of the lower panels 14.

[0037] The lower panel 14 of this invention differs from the lower panel structure in the prior art. In the prior art, the lower panel and the upper pedal are an integral structure, requiring disassembly of both during maintenance, necessitating the removal of numerous fixing bolts and components, which is time-consuming and labor-intensive. This invention, by machining a foot pedal clearance part 15 at the front end of the lower panel 14, allows the upper pedal to be installed independently. Thus, during maintenance, only the lower panel 14 needs to be removed, greatly improving maintenance efficiency. The lower panel 14 of this invention is bolted to the frame 1 for easy assembly and disassembly.

[0038] Furthermore, the distance between the two third steel pipes 9 is less than the distance between the two first steel pipes 7, and the distance between the two first steel pipes 7 is less than the distance between the two fifth steel pipes 11; a front bottom plate support plate 12 is welded and fixed to the inner side of the second steel pipe 8, and a rear bottom plate support plate 13 is welded and fixed to the inner side of the third steel pipe 9.

[0039] The distance between the two first steel pipes 7 is determined by the distance between the two front support legs 5 on the main body 2 of the top support frame. The two front support legs 5 are each welded and fixed with a first bending fixing plate 42. The first steel pipe 7 is fixedly connected to the first bending fixing plate 42 by M14 combination bolts.

[0040] Since the second steel pipe 8 and the third steel pipe 9 are located at the position where the upper step is set, reducing the distance between the two third steel pipes 9 can leave more installation space for the upper step, making it easier to set a larger upper step and improve the convenience of getting in and out of the high-position cab.

[0041] The two fifth steel pipes 11 are located on the left and right sides of the machine cover. Therefore, increasing the distance between the two fifth steel pipes 11 can increase the installation space of the machine cover 43, making the usable space inside the machine cover 43 larger.

[0042] To facilitate the quick opening and locking of the cover 43, a cover fixing buckle (not shown in the figure) is welded and fixed to the rear end of the third steel pipe 9. The fixing parts on the cover 43 cooperate with the cover fixing buckle to lock the cover 43.

[0043] The front bottom plate support plate 12 is used to support and fix the front bottom plate 44, and the rear bottom plate support plate 13 is used to support and fix the rear bottom plate 45. Both the front bottom plate support plate 12 and the rear bottom plate support plate 13 are provided with threaded holes. The front bottom plate 44 is fixed to the front bottom plate support plate 12 by bolts, and the rear bottom plate 45 is fixed to the rear bottom plate support plate 13 by bolts.

[0044] Furthermore, the support frame 4 includes a lower fixing plate 20, a lower support tube 21, an upper support tube 22, an upper fixing plate 23, and an L-shaped connecting plate 24. The lower end of the lower support tube 21 is welded and fixed to the lower fixing plate 20, the upper end of the lower support tube 21 is welded and fixed to the lower end of the upper support tube 22, the upper end of the upper support tube 22 is welded and fixed to the upper fixing plate 23, and the L-shaped connecting plate 24 is welded and fixed to the front side wall of the lower support tube 21. The lower support tube 21 is set vertically, and the upper support tube 22 is set inclined towards the rear of the vehicle.

[0045] Because the two front support legs 5 on the main body 2 of the top cover frame are lengthened in this utility model, while the slope of the front support legs is not changed, the main body 2 of the top cover frame will move backward as a whole while being raised. Therefore, the upper support tube 22 is tilted backward so that it can be fixedly connected to the lower end of the two rear support legs 3 on the main body 2 of the top cover frame.

[0046] Designing the support frame 4 in this way requires no modification to the frame 1. The frame 1 can still use the existing holes, reducing modification costs.

[0047] L-shaped connecting plate 24 is used to connect the fifth steel pipe 11 on the support beam assembly 6. The fifth steel pipe 11 is fixedly connected to the L-shaped connecting plate 24 by bolt assembly.

[0048] In this utility model, both the lower support tube 21 and the upper support tube 22 are hollow rectangular steel tubes. Through holes are provided on the lower fixing plate 20 and the upper fixing plate 23, so that the support frame 4 can circulate gas while playing a supporting role, allowing air to enter the cab through the support frame 4.

[0049] Furthermore, two footboards are installed on both the left and right sides of the frame 1. The two footboards are symmetrically arranged on the left and right sides of the frame 1. The footboards include a lower footboard step 35, a middle footboard step 36, and an upper footboard step 37 arranged sequentially from bottom to top. The length of the upper footboard step 37 is greater than the length of the middle footboard step 36, and the length of the middle footboard step 36 is greater than the lower footboard step 35. A mudguard connecting plate 25 is welded and fixed to the front end of the lower footboard step 35 and the middle footboard step 36. The mudguard connecting plate 25 is an arc-shaped plate, and two mudguard connecting holes 26 are opened on the mudguard connecting plate 25.

[0050] In this invention, the upper step and the lower panel 14 are separately installed. When removing the lower panel 14, the upper step does not need to be removed. Therefore, when the forklift requires maintenance, only the side panel needs to be removed; the upper step does not need to be disassembled. This reduces maintenance difficulty and improves maintenance efficiency.

[0051] The width of the lower step 35 of the forklift platform is 20mm larger than the width of the middle step 36, and the width of the middle step 36 is 40mm larger than the width of the upper step 37. Combined with these length differences, the steps create a sense of hierarchy and facilitate the driver's entry and exit from the forklift, especially when dismounting. Since the upper step 37 is the longest, it is easily accessible, solving the problem of finding the step position when dismounting in existing technologies. Furthermore, the gradually increasing step width from top to bottom reduces the risk of leg bumps when getting on and off the forklift.

[0052] The curvature of the mudguard connecting plate 25 is the same as that of the mudguard 41. Two mudguard connecting holes 26 are provided on the mudguard connecting plate 25. Two M12 bolts are used to fix the mudguard connecting plate 25 to the mudguard 41 through the two mudguard connecting holes 26.

[0053] The mudguard connecting plate 25 is used to position the front end of the lower step 35 of the upper pedal and the middle step 36 of the upper pedal. Since the height of the upper step 37 of the upper pedal is higher than the height of the mudguard 41, the upper end of the mudguard connecting plate 25 is fixedly connected to the front end of the upper step 37 of the upper pedal through the first support connecting plate 27.

[0054] The lower step 35, the middle step 36, and the upper step 37 of the boarding pedal are parallel to each other. The first support connecting plate 27 serves to support and fix the front end of the upper step 37 of the boarding pedal.

[0055] The lower step 35 of the upper step has three frame connection holes. The lower step 35 of the upper step is installed and fixed to the box support plate of the frame 1 by three M8 bolts through the three frame connection holes.

[0056] The rear ends of the lower step 35 of the boarding pedal, the middle step 36 of the boarding pedal, and the upper step 37 of the boarding pedal are all fixedly connected to the second support connecting plate 28.

[0057] Furthermore, a frame connecting plate 29 is welded and fixed to the inner side of the upper step 37 of the boarding pedal, and two frame connecting holes are provided on the frame connecting plate 29; a first side cover support plate 30 is welded and fixed to the middle of the inner side of the upper step 37 of the boarding pedal, and a second side cover support plate 31 is welded and fixed to the front of the inner side of the upper step 37 of the boarding pedal.

[0058] The frame connecting plate 29 is fixed to the support longitudinal beam 46 of the frame 1 using two M12 bolts through the frame connecting holes. Similarly, the first side cover support plate 30 and the second side cover support plate 31 are fixed to the support longitudinal beam 46 of the frame 1 using one M12 bolt.

[0059] Furthermore, side doors 32 are installed on the left and right sides of the main body 2 of the roof support frame. The side doors 32 are hinged to the main body 2 of the roof support frame via hinges 33. A side door handle 34 is installed on the lower edge of the outer wall of the side door 32.

[0060] Each side door 32 is hinged to the rear support leg 3 of the overhead guard body 2 via two hinges 33. Side door handles 34 are installed on the side doors 32 to facilitate the driver's opening and closing of the side doors 32.

[0061] To facilitate the driver's entry and exit from the forklift, a first handle 38 is preferably welded and fixed to the lower outer wall of the front support leg 5, and a second handle 47 is fixed to the side wall of the hood 43. After the driver opens the side door 32, he can easily get on the forklift by holding the first handle 38 with his left hand and the second handle 47 with his right hand, thus improving the safety of getting on and off the forklift.

[0062] Preferably, the two side doors 32 are flanged and straight airbags (not shown in the figure) are installed at the edge. When the doors are closed, the straight airbags fit into the side panels to improve the sealing of the cab.

[0063] The design concept of this utility model is to increase the height vertically. The front support leg 5 of the overhead guard body 2 is lengthened, and a support frame 4 is added between the rear support leg 3 and the frame 1 to increase the height of the cab. The left and right support beam assemblies 6 and the surrounding upper panels are used to achieve reinforcement and sealing. Reasonable handles for getting on and off the vehicle and an independent boarding step mechanism separate from the lower panel 14 are set up to allow the driver to get on and off the vehicle safely and conveniently. This utility model solution does not change the internal structure of the forklift, such as the frame 1, counterweight, and instrument panel, and still uses existing standard parts, avoiding the development of a large number of molds and avoiding resource waste. This allows the modified structure solution to be applied to different series and different models, achieving universality.

[0064] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
