Description

Balanced electric forklift

(1) Technical field

The present invention relates to a forklift, in particular to a counterbalanced electric forklift.

(2) Background technology

 The current counterbalanced electric forklifts are unable to achieve: a wide view of cargo lifting, a self-locking function of the mast tilting forward, and an unobstructed cab space, which need to be improved.

(3) Contents of the invention

The technical problem to be solved by the invention is to provide a counterbalanced electric forklift with a wide view of cargo lifting, a self-locking function of the mast tilting forward, and an obstacle-free cab space.

The technical solution created by the present invention is: a counterbalanced electric forklift, which consists of a mast system (1), a hydraulic system (2), a drive system (3), a body system (4), and an electric control system (5). The mast system (1) and the cab of the body system (4) are connected by an oil cylinder (8), which is characterized in that the oil cylinder (8) is a double-jointed pin bearing oil cylinder at the tail of the inclined cylinder, and the drive system (3) A combined driving axle (7) (such as patent CN2707583Y) with driving wheels running inside is housed, wherein a built-in load-bearing chain (6) is installed on the upper end of the door frame, and an anti-tilt self-locking support wheel (9) is installed on the lower end of the door post.

The invention has the advantages of wide vision for cargo lifting, self-locking function of mast tilting forward, and barrier-free cab space. the

Accompanying drawing 2 is the top view structure diagram of the present invention.

(5) Specific implementation methods

Refer to the attached picture:

A counterbalanced electric forklift, which consists of a mast system (1), a hydraulic system (2), a drive system (3), a body system (4), and an electric control system (5). The mast system (1) and the body The cabs of the system (4) are connected by an oil cylinder (8), which is characterized in that the oil cylinder (8) is a combined type in which the oil cylinder (8) is supported by a double-jointed pin shaft at the tail of the cylinder, and the drive system (3) is equipped with a drive wheel to run. Drive axle (7) (as patent CN2707583Y), wherein built-in load-bearing chain (6) is equipped with on the upper end of door frame, anti-forward self-locking support wheel (9) is equipped with at the lower end of door post.

advantage:

1. It is driven by the front axle of the differential gearbox, which has excellent bearing capacity, faster acceleration performance, reasonable and reliable structure, AC motor, fully enclosed, and maintenance-free.

2. The built-in load-bearing chain structure is used for cargo lifting, which is safe, novel and efficient. It is equipped with double tie rod cylinders, left and right balance, hydraulic pressure, and easy maintenance.

3. The ground self-locking support wheel is installed at the lower end of the gate post, which is the best innovative solution for the forklift to have the self-locking function of the mast tilting forward according to the national standard JB/T2391-2007 technical condition 3.4.1 for counterbalanced forklifts.

4. The tail support of the tilting cylinder is designed as a double-joint pin shaft support, the total length is shortened, the force is better, and the cab space is unobstructed. 5. Perfect flexibility, multi-part closed cover, compact and smart appearance are all new highlights of this car.

Specific manufacturing method:

1. The important part of the counterbalanced forklift is the drive axle. Large-scale forklifts are made of integral cast steel. The combined axle housing design of this forklift is specially designed for models below 1.5T. Thick-walled seamless pipes are selected as the load-bearing support bridge. Pipe fittings, axle housing and its differential reducer and transmission parts, brake drums, tires, etc. are all carried on the axle tube and combined.

2. A new type of forklift built-in load-bearing chain structure; the sprocket group is placed on the upper connecting plate, the upper end of the load-bearing chain is pinned to the chain seat in the outer door post, the lower end is pinned to the roller plate, and the chain tightening bolt is set on the On the roller plate, during operation, as the upper connecting plate rises, the load-bearing chain is close to the J-shaped track edge on the outside of the inner doorpost and rises steadily. When resetting, the load-bearing chain is placed in the outer doorpost. It has compact structure, stable force, wide field of vision, safety and reliability, and has obtained a patent (patent number: ZL201420252782.3).

3. The tilt cylinder of the forklift adopts a new structure support method: the double joint pin shaft support at the tail of the cylinder. Both ends of the traditional forklift tilting cylinder are linear hinged joints. In this design, the tail is changed to a support cap, and the pin shafts are placed on both sides of the support cap. Therefore, the total length of the tilting cylinder is shortened, which is beneficial to the installation and maintenance on both sides of the driving platform, and does not require It is very convenient and reliable to hinder the driver's up and down space.

4. This forklift uses the latest design of a safety measure, according to the national standard JB/T2391-2007, the forklift should have the self-locking function of the mast tilting forward. When the mast leans forward, a support wheel against the ground is added at the lower end of the gate post; when the mast leans forward beyond the design value, the support wheel exerts pressure on the ground and acts as a safe support leg, which will never continue Overturned forward. And this structure adopts the bolt installation type, which can be conveniently disassembled or adjusted according to different requirements of the use environment or by selecting support wheels of different diameters.
