Description

Technical Field

[0001] The invention belongs to the technical field of forklift masts, and in particular relates to an anti-dumping forklift mast. Background Art

[0002] Forklifts are industrial handling vehicles, which refer to various wheeled handling vehicles that load and unload, stack and transport palletized goods over short distances. The International Organization for Standardization ISO / TC110 calls them industrial vehicles. They are often used for transporting large objects in warehouses and are usually powered by fuel engines or batteries.

[0003] At present, the existing forklift masts are equipped with forks, and the goods on the pallet are transported by the forks. However, most forklift masts are not equipped with corresponding limit mechanisms, and the goods placed on the forks cannot be restricted, which is not conducive to the stability of the goods and may cause the goods to tip over during the transport process, posing certain safety hazards. For this reason, we propose an anti-tipping forklift mast. Summary of the invention

[0004] The object of the present invention is to provide a forklift mast that is anti-dumping, so as to solve the existing problems raised in the above-mentioned background technology.

[0005] The cam is provided with a plurality of levers, and the lever is provided with a plurality of levers, and the lever is provided with a plurality of levers at the bottom ends of the levers, and the lever is provided with a plurality of levers at the bottom ends of the levers.

[0006] Preferably, a return spring is arranged inside the sliding sleeve, and two ends of the return spring are fixedly connected to the inner wall of the sliding sleeve and one end of the sliding block respectively.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. By utilizing the gravity of the goods on the pallet, when the fork is inserted into the bottom of the pallet, the thrust formed on the push plate causes the push plate to drive the slider to move deep inside the sliding sleeve, and cooperates with the meshing connection between the tooth groove and the gear block to drive the gear block to rotate with the clamp rod, thereby realizing the function of driving the clamp rod to clamp and limit the goods with the clamp plate, ensuring the stability of the goods and avoiding tipping.

[0014] 2. By setting a reset spring inside the sliding sleeve and utilizing the reset elastic force of the reset spring, after unloading the goods, the sliding block is pushed to extend outward, thereby driving the push plate to reset, and utilizing the tooth groove to drive the gear block to rotate in the opposite direction, thereby restoring and unfolding the clamping rod and the clamping plate to facilitate unloading of the goods.

The cargo pallet 10 is flipped over to gradually fit the two sides of the cargo, and the movable block 21 and the pin 22 are used to realize the mobility of the splint 20, so that the surface of the splint 20 can be stably fitted with the cargo, thereby achieving the purpose of clamping and limiting. When unloading the cargo, the fork 6 is pulled out from the bottom of the pallet, and the cargo and the push plate 14 are gradually separated. Under the action of the reset spring 10, the slider 11 is pushed to extend outward and reset, thereby cooperating with the tooth groove 12 to drive the gear block 17 to rotate in the opposite direction, so that the clamp rod 16 and the splint 20 are reset and unfolded for unloading. Such a design makes it possible to utilize the gravity of the cargo on the pallet to form a thrust on the push plate 14 in the process of shipping the cargo, so as to realize the function of driving the clamp rod 16 and the splint 20 to clamp and limit the cargo, thereby ensuring the stability of the cargo and avoiding tipping.
