[0002] A forklift is an industrial handling vehicle, referring to various wheeled handling vehicles for loading, unloading, stacking, and short-distance transportation of palletized goods. It is commonly used for transporting large objects in warehouses and is usually powered by a fuel engine or a battery.

[0003] When the existing forklift lifts goods and climbs a slope, due to the forward center of gravity of the goods and limited power of the forklift, the climbing ability of the forklift on a slope with a relatively large gradient is weakened, increasing the risk of climbing the slope and affecting the use of the forklift. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a forklift with strong climbing ability. By setting widened fixed wheels, an electric winch, a steel cable, and a hook, before the forklift lifts goods and climbs a slope with a relatively large gradient, the steel cable on the electric winch is lowered, and the steel cable is wound around a fixed structure on the top of the slope through the hook. One end of the forklift's fork faces the slope. When the forklift climbs the slope, the widened fixed wheels increase the contact area between the vehicle body and the ground, thereby increasing the upward frictional force during climbing. The speed at which the electric winch tightens the steel cable is the same as the climbing speed of the vehicle body, so that when the forklift climbs the slope, it not only has the power of the vehicle body itself but also an upward pulling force driven by the electric winch, enabling the forklift to climb a slope with a larger gradient, reducing the risk of climbing, and meeting the climbing use requirements of the forklift. The problems in the background art can be effectively solved.

[0005] To achieve the above object, the utility model provides the following technical solution: A forklift with strong climbing ability, including a chassis and a vehicle body installed on the upper side of the chassis. An electric winch is installed at one end of the chassis. A steel cable is wound around the rotating shaft of the electric winch. A hook is installed at one end of the steel cable. Widened fixed wheels are installed on the chassis near the side of the electric winch. A support structure is arranged between the two widened fixed wheels. A lifting structure is installed on the upper part of one end of the chassis near the electric winch. There are two widened fixed wheels on each side of the chassis.

[0006] Further, a fork rack is arranged on one side of the lifting structure. A limit card slot is arranged on the fork rack. The fork is installed on the fork rack through the limit card slot.

[0007] Further, a limit hook is arranged at the position of the fork near the limit card slot. A driver's cab is installed on the upper side of the vehicle body.

[0008] Further, a steering wheel is installed on the chassis away from the side of the widened fixed wheels. The widened fixed wheels are power output wheels.

[0009] Further, the chassis is connected to the vehicle body by bolts, and the lifting structure is connected to the chassis by bolts.

[0010] Further, the sliding structure on the lifting structure is connected to the forklift carriage by bolts, and the forklift forks are connected to the forklift carriage through the limit hooks and the limit grooves.

[0011] Further, the electric winch is connected to the chassis by bolts, and the widened fixed wheel is connected to the chassis through the support structure.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. Through the arranged widened fixed wheel, electric winch, steel cable and hook, before the forklift lifts the goods and climbs a slope with a relatively large gradient, the steel cable on the electric winch is lowered, and the steel cable is wound around the fixed structure on the top of the slope through the hook. One end of the forklift forks faces the slope. When the forklift climbs the slope, the widened fixed wheel increases the contact area between the vehicle body and the ground, thereby increasing the upward frictional force during climbing. The speed at which the electric winch tightens the steel cable is the same as the speed at which the vehicle body climbs the slope, so that when the forklift climbs the slope, it not only has the power of the vehicle body itself, but also has an upward pulling force driven by the electric winch, enabling the forklift to climb a slope with a larger gradient, reducing the risk of climbing the slope, and meeting the climbing use requirements of the forklift.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , this embodiment provides a technical solution: a forklift with strong climbing ability, including a chassis 14 and a vehicle body 4 installed on the upper side of the chassis 14. An electric winch 8 is installed at one end of the chassis 14. A steel cable 9 is wound around the rotating shaft of the electric winch 8. One end of the steel cable 9 is installed with a hook 10. A widened fixed wheel 2 is installed on the side of the chassis 14 close to the electric winch 8. A support structure 12 is arranged between the two widened fixed wheels 2. A lifting structure 6 is installed on the upper part of one end of the chassis 14 close to the electric winch 8. There are two widened fixed wheels 2 on each side of the chassis 14.

[0021] As Figures 1-4 shown, before the forklift lifts the goods and moves up the slope, there is a certain height between the fork 1 and the ground. Then, the steel cable 9 on the electric winch 8 is removed, and the steel cable 9 is wound around the fixed structure on the upper part of the slope through the hook 10. Then, the forklift drives onto the slope. The power output module in the vehicle body 4 drives the widened fixed wheels 2 to rotate, so that the vehicle body 4 moves to the upper side of the slope. The widened fixed wheels 2 increase the contact area between the vehicle body and the ground, improve the friction force during climbing, and thus make the vehicle body 4 more stable when climbing up the slope. When the vehicle body 4 is climbing the slope, the driving speed of the vehicle body 4 is the same as the speed at which the electric winch 8 winds the steel cable 9, so that the vehicle body 4 obtains an additional pulling force from the electric winch 8 when climbing up the slope, increases the power of the vehicle body 4, and improves the climbing ability of the vehicle body 4.

[0022] A fork rack 7 is arranged on one side of the lifting structure 6. A limit card slot 11 is arranged on the fork rack 7. The fork rack 7 is installed with a fork 1 through the limit card slot 11. The fork 1 is fixed in the limit card slot 11 through a limit hook 13. When it is necessary to adjust the distance between the forks 1, the forks 1 can be moved along the limit card slot on the fork rack 7, so as to adjust the distance between the two forks 1. The lifting structure 6 can drive the fork rack 7 and the fork 1 to move up and down, so as to facilitate the handling of goods.

[0023] A limit hook 13 is arranged at the position of the fork 1 close to the limit card slot 11. A cab 5 is installed on the upper side of the vehicle body 4.

[0024] A steering wheel 3 is installed on the side of the chassis 14 away from the widened fixed wheel 2. The widened fixed wheel 2 is a power output wheel. The widened fixed wheel 2 increases the contact area between the power wheel of the vehicle body 4 and the ground, increases the friction force, and improves the climbing ability of the vehicle body 4 when climbing the slope.

[0025] The chassis 14 is bolted to the vehicle body 4, and the lifting structure 6 is bolted to the chassis 14.

[0026] The sliding structure on the lifting structure 6 is bolted to the forklift carriage 7, and the forklift fork 1 is connected to the forklift carriage 7 through the limit hook 13 and the limit slot 11.

[0027] The electric winch 8 is bolted to the chassis 14, and the widened fixed wheel 2 is connected to the chassis 14 through the support structure 12.

[0028] The working principle of the forklift with strong climbing ability provided by the present utility model is as follows: As Figures 1-4 shown, before the forklift lifts the goods and moves up the slope, there is a certain height between the forklift fork 1 and the ground. Then, the steel cable 9 on the electric winch 8 is removed, and the steel cable 9 is wound around the fixed structure on the upper part of the slope through the hook 10. Then, the forklift drives onto the slope, and the power output module in the vehicle body 4 drives the widened fixed wheel 2 to rotate, so that the vehicle body 4 moves towards the upper side of the slope. The widened fixed wheel 2 increases the contact area between the vehicle body and the ground, improves the friction force during climbing, and thus makes the vehicle body 4 more stable when climbing upwards. When the vehicle body 4 is climbing, the traveling speed of the vehicle body 4 is the same as the speed at which the electric winch 8 winds the steel cable 9, so that the vehicle body 4 obtains an additional pulling force from the electric winch 8 when climbing upwards, increases the power of the vehicle body 4, and improves the climbing ability of the vehicle body 4.

[0029] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
