[0002] A forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles for loading and unloading, stacking and short-distance transportation of palletized goods. Electric forklifts are powered by electric motors and batteries, with a carrying capacity of 1.0 to 8.0 tons and an operating channel width of 3.5 to 5.0 meters. Because they are pollution-free and low-noise, they are widely used in indoor operations and other working conditions with high environmental requirements, such as the pharmaceutical and food industries. As people pay more attention to environmental protection, electric forklifts are gradually replacing internal combustion forklifts.

[0003] An existing walking electric off-road forklift (publication number: CN208102112U) has at least the following disadvantages: the above-mentioned device simulates the structure of human feet through bionic wheels and bionic foot assemblies, so that the forklift can enter dry land and paddy fields for work. However, the bionic wheels are installed on the front side of the forklift, and the rear support wheels mainly support the goods transported by the forklift. When the rear support wheels travel in muddy and soft land, they are easy to sink into the mud, which makes it difficult for the forklift to travel and reduces the transportation efficiency of the forklift. For this reason, we propose the utility model. Utility Model Content

[0024] In this embodiment, two traveling wheels 3 are arranged on the front side of the forklift body 1, and a plurality of grab plates 301 are fixed to the outer circumferential wall of the traveling wheel 3. The plurality of grab plates 301 are evenly distributed along the circumference of the traveling wheel 3, and the two traveling wheels 3 are distributed on both sides of the driving wheel of the forklift body 1. Through the setting of the supporting structure, when the forklift is used on a muddy ground, the staff connects an external inflating device through the air intake pipe 203 to fill the air bag 201 with gas to push the support plate 202 out of the mounting groove 2, and the support plate 202 and the air bag 201 are supported on the load-bearing side of the forklift body 1, and then the two traveling wheels 3 are installed on both sides of the driving wheel of the forklift body 1, and the forklift is started. When the vehicle body 1 and the forklift body 1 are moving, the several gripping plates 301 on the outer circumferential walls of the two traveling wheels 3 firmly grip the ground, so that the driving wheels of the forklift body 1 rely on the gripping plates 301 to move on the muddy ground, and at the same time, the support plates 202 and the airbags 201 replace the support wheels for support on the load-bearing side of the forklift body 1. When the forklift body 1 is moving, the arc-shaped bottom surface of the support plate 202 slides on the muddy ground, and at the same time, the support plates 202 and the airbags 201 can prevent the load-bearing side of the forklift body 1 from sinking into the ground, thereby ensuring that the forklift body 1 can still move safely in harsh environments, and improving the transportation efficiency of the forklift body 1 on muddy ground.

[0025] In this embodiment, the traveling wheel 3 is provided with a fixed shaft 4, one end of the fixed shaft 4 is fixed to the driving wheel rotating shaft of the forklift body 1, and the other end of the fixed shaft 4 is provided with a plurality of threaded holes. A plurality of bolts are slidably inserted into one side of the traveling wheel 3, and the bolts are threadedly connected with the threaded holes. After the forklift body 1 is started, the traveling wheel 3 rotates synchronously with the driving wheel of the forklift body 1 through the fixed shaft 4, so that the traveling wheel 3 replaces the driving wheel of the forklift body 1, ensuring that the forklift body 1 will not slip on muddy ground. At the same time, the fixed shaft 4 and the traveling wheel 3 are fixed by bolts, so that the traveling wheel 3 is easy to disassemble and assemble in different environments.

[0027] In this embodiment, a limit rod 6 is slidably inserted inside the left mounting tube 5, and the bottom end of the limit rod 6 is fixed to the top surface of the mounting plate 503. When the screw 501 rotates to drive the threaded sleeve 502 to extend and retract, the matching arrangement of the limit rod 6 and the mounting plate 503 can limit the threaded sleeve 502, preventing the threaded sleeve 502 from rotating with the screw 501, thereby ensuring the extension and retraction effect of the threaded sleeve 502.

[0028] In this embodiment, magnetic strips 7 are fixed on both sides of the inner wall of the installation groove 2, and both sides of the support plate 202 are magnetically connected to the magnetic strips 7. The magnetic strips 7 are existing technology, and the support plate 202 is made of iron. When the staff retracts the airbag 201 and the support plate 202, the support plate 202 is magnetically attracted to the two sides of the ejection and the magnetic strips 7, so that the support plate 202 is not easy to fall out after entering the installation groove 2.

[0029] Working principle: When the forklift is used on muddy ground, the staff connects the inflatable device to the air inlet pipe 203, fills the airbag 201 with gas, and pushes the support plate 202 out of the installation slot 2. The support plate 202 and the airbag 201 are supported on the load-bearing side of the forklift body 1. Then, the two traveling wheels 3 are installed on both sides of the driving wheel of the forklift body 1, and the forklift body 1 is started. When the forklift body 1 moves, the several gripping plates 301 on the outer wall of the two traveling wheels 3 firmly grip the ground, so that the forklift body 1 The driving wheel of the forklift body 1 moves on the muddy ground by relying on the gripping plate 301, and at the same time, the support plate 202 and the airbag 201 replace the support wheel for support on the load-bearing side of the forklift body 1. When the forklift body 1 moves, the arc-shaped bottom surface of the support plate 202 slides on the muddy ground, and at the same time, the support plate 202 and the airbag 201 can prevent the load-bearing side of the forklift body 1 from sinking into the ground, thereby ensuring that the forklift body 1 can still move safely in harsh environments. After the forklift body 1 is started, the traveling wheel 3 is connected to the forklift body 1 through the fixed shaft 4. The driving wheels of the forklift body 1 rotate synchronously, so that the traveling wheels 3 replace the driving wheels of the forklift body 1, ensuring that the forklift body 1 will not slip on muddy ground. At the same time, the fixed shaft 4 and the traveling wheels 3 are fixed by bolts, so that the traveling wheels 3 are easy to disassemble and assemble in different environments. When the staff disassembles and assembles the traveling wheels 3, they can start the driving motor to drive the screw 501 to rotate, so that the bottom end of the threaded sleeve 502 extends from the inside of the mounting tube 5, so that the threaded sleeve 502 contacts the ground through the mounting plate 503 to move the forklift body 1 is lifted up, so as to facilitate the staff to disassemble and assemble the traveling wheel 3. When the screw rod 501 rotates to drive the threaded sleeve 502 to extend and retract, the matching arrangement of the limit rod 6 and the mounting plate 503 can limit the threaded sleeve 502 to prevent the threaded sleeve 502 from rotating with the screw rod 501, thereby ensuring the extension and retraction effect of the threaded sleeve 502. When the staff retracts the airbag 201 and the support plate 202, the support plate 202 is magnetically attracted to the two sides of the ejection and the magnetic strip 7, so that the support plate 202 is not easy to fall out after entering the mounting groove 2.
