Description

Technical Field

[0001] This application belongs to the field of forklift technology, and in particular to a converted oil-powered forklift. Background Technology

[0002] Forklifts are industrial material handling vehicles, referring to various wheeled handling vehicles used for loading, unloading, stacking, and short-distance transport of palletized goods. The International Organization for Standardization (ISO / TC110) refers to them as industrial vehicles. They are commonly used for transporting large items in warehouses and are typically powered by either internal combustion engines or batteries.

[0003] With the rise of the logistics industry, the management of logistics warehouses is receiving increasing attention. Forklifts are indispensable for handling goods in logistics warehouses, playing a very important role in the logistics system and being the mainstay of goods handling equipment.

[0004] Converting a diesel forklift to an electric forklift, also known as "forklift oil-to-electric conversion," involves removing the diesel engine, transmission, and mechanical driveshaft from the original fuel-powered forklift while keeping the basic platform structure unchanged. This is then replaced with an AC motor, lithium battery pack, all-AC electronic control system, and a high-ratio gearbox, transforming it into a lithium-ion battery-powered electric forklift. Its advantages are simplicity, convenience, speed, and low cost. This solution helps manufacturers quickly convert fuel-powered forklifts into lithium-ion battery-powered forklifts and bring them to market, reducing the cost burden of purchasing new vehicles and addressing the environmental issues associated with internal combustion forklifts.

[0005] However, when using existing oil-to-electric forklifts, it is necessary to use the forklift to unload goods from the truck. The operator needs to drive the forklift to the side of the truck and move the goods off the truck perpendicularly. When the space around the truck is small, the forklift cannot move the goods on the truck perpendicularly. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an electric forklift that is converted from oil, which allows the operator to easily change the forklift's forking angle according to the site, and reduces the impact of space on the forklift's transport of goods.

[0007] To achieve the above objectives, this application provides the following technical solution:

The locking hole and the groove are both rectangular in cross-section, the locking rod is rectangular in cross-section, the through hole is rectangular in cross-section, and the upper surface of the pin abuts against the lower surface of the limit rod.

[0012] As a preferred embodiment, a connecting mechanism is provided between the fork and the crossbar. The connecting mechanism includes a first plate fixedly connected to the upper surface of one end of the fork, a second plate fixedly connected to one end of the first plate, a third plate fixedly connected to one end of the second plate, and a locking member provided on the end face of one end of the fork for pressing the second plate against the upper crossbar.

[0013] As a preferred embodiment, the locking component includes a locking plate fixedly connected to one end face of the fork near the first plate, a locking hole formed on the locking plate, and a locking rod inserted into the locking hole, wherein the locking rod and the fork are located on opposite sides of the crossbar.

[0014] As a preferred embodiment, a positioning tooth is fixedly connected to both lower surfaces of the second plate, and a spring plate is fixedly connected between the two positioning teeth. The spring plate is arranged in an arc shape and bent downwards. After the spring plate is finished, it extends beyond the positioning tooth. A positioning rack is fixedly connected to the upper surface of the upper crossbar. The positioning rack is arranged along the length of the crossbar, and the positioning tooth meshes with the positioning rack.

[0015] As a preferred embodiment, a support rod is rotatably connected to each of the two side walls of the fork. The distance from the pivot of the support rod to the end of the fork near the first plate is less than the distance from the pivot of the support rod to the end of the fork away from the first plate. A first rod is rotatably connected to the upper surface of the support rod. A U-shaped block is fixedly connected to one end of the first rod. A second rod is rotatably connected between the inner walls of the two sides of the U-shaped block.

[0018] Compared with the prior art, this application has the following advantages:

[0019] 1. In this application, two crossbeams are fixedly connected to the mast, and a support frame is slidably connected to the crossbeams. Under the action of the limiting mechanism, the mounting frame is rotated. After the mounting frame rotates 90 degrees, it is perpendicular to the support frame. Then, the forks are installed on the crossbar. The forklift only needs to unload the goods from the truck at an angle parallel to the truck. Since the length of the forklift is greater than the width of the forklift, it can adapt to the minimum distance between the truck and the surrounding obstacles in the place where the truck is parked, which is the width of the forklift.

[0020] 2. In this application, the pin is removed, and under the action of the torsion spring's restoring force, the support rod rotates, and the first rod and the second rod rotate. The second rod rotates out of the support groove, and one end of the second rod abuts against the stop bar. At this time, one end of the support rod is supported on the ground. The operator adjusts the position of the forks by using the end of the forks away from the first plate, and then places the second plate on the crossbar. Then, the locking bolt is tightened and the locking rod is inserted. With this setting, the structure is simple and the operation is convenient, making it easy for a single operator to install and remove the forks. Attached Figure Description
