Description

Technical Field

[0001] The utility model belongs to the technical field of handling equipment, and more specifically, particularly relates to a steerable handling device. Background Art

[0002] A pallet truck is a small handling device for transporting palletized goods. This device is usually used with pallets to transport heavy goods that cannot be directly held by hand. At present, when a pallet truck is transporting goods, it is necessary to insert the fork into the free hole of the pallet, and then drive the hydraulic system manually to achieve the lifting and lowering of the palletized goods. Finally, the pallet truck is pulled by manpower to complete the transfer and transportation of the goods. During the transfer and transportation of goods, the overall direction of the pallet truck is often adjusted according to the placement direction and position of the goods. However, the overall direction of the pallet truck requires repeated manual dragging of the pallet truck for U-turns. If the site space is limited, it will cause the overall direction adjustment of the pallet truck to be inconvenient. It can be seen that the traditional pallet truck itself does not have the cargo steering function, and the cargo handling steering operation is extremely inconvenient, and the transportation and placement efficiency of the goods is low.

The front side surface is hinged with a fork plate 2, and the upper side surface of the fork plate 2 is connected with a baffle plate 3 by bolts; the upper side surface of the fork plate 2 is slidably connected with a telescopic pad 1, and the telescopic pad 1 is connected to the upper side surface of the slide 12 by bolts; the front end of the hydraulic rod 4 is hinged with the fork plate 2, and the rear end of the hydraulic rod 4 is hinged with a support plate 5, and the hydraulic rod 4 is connected to the hydraulic oil supply station 11 by an oil pipe; the telescopic motor 13 is connected to the controller 10 by a wire, and the telescopic motor 13 is connected to the rear side surface of the fork plate 2 by bolts, and a threaded rod 19 is installed on the motor shaft of the telescopic motor 13; a convex plate is provided on the front side surface of the push frame 9, and a rotating motor 15 is connected to the upper side surface of the convex plate by bolts, and a rotating rod 16 is installed on the motor shaft of the rotating motor 15, and a gear 20 is welded to the bottom end of the rotating rod 16.

[0022] When the utility model is carrying out the cargo handling work, the porter holds the handle frame 8 to push the push frame 9, and the push frame 9 pushes the pallet truck to the lower side of the cargo pallet. At this time, the telescopic pad 1 is located at the lower side of the cargo pallet, and then the hydraulic oil supply station 11 pumps oil to the hydraulic rod 4. At this time, the telescopic rod of the hydraulic rod 4 retracts, and the hydraulic rod 4 drives the fork plate 2 hinged on the support plate 5 to flip upward, and the fork plate 2 drives the telescopic pad 1 to lift the cargo pallet upward. After the cargo pallet leaves the ground, the porter holds the handle frame 8 to pull the pallet truck to transport the cargo to the vicinity of a suitable placement position. If the cargo needs to be turned and placed, the rotating motor 15 drives the gear 20 welded to the bottom end of the rotating rod 16 to rotate. Since the gear 20 is meshed with the internal tooth structure of the rotating frame 14, the gear 20 drives the support plate 5 welded to the front end of the rotating frame 14 to rotate along the internal tooth structure of the rotating frame 14, and the support plate 5 drives the fork plate 2 hinged on the front side to rotate synchronously, until Until the fork plate 2 carrying the cargo pallet rotates to a suitable angle position, the telescopic motor 13 then drives the threaded rod 19 to rotate. Since the outer side threads of the threaded rod 19 are engaged with the convex threaded through holes of the slide 12, the threaded rod 19 drives the telescopic pad 1 connected by bolts on the upper side of the slide 12 to move forward along the six groups of grooves of the fork plate 2, and pushes the turned cargo horizontally to the upper side of the placement position. Finally, the hydraulic oil supply station 11 supplies oil to the hydraulic rod 4, and the telescopic rod of the hydraulic rod 4 extends. The hydraulic rod 4 pushes the fork plate 2 to flip downward, and the fork plate 2 drives the telescopic pad 1 to place the cargo pallet downward until the cargo pallet touches the ground. At this time, the telescopic pad 1 is separated from the cargo pallet, and the telescopic motor 13 drives the threaded rod 19 to rotate in the opposite direction. The threaded rod 19 drives the telescopic pad 1 connected by bolts on the upper side of the slide 12 to move backward along the six groups of grooves of the fork plate 2, and the telescopic pad 1 is separated from the lower side area of ​​the cargo pallet, completing the steering and handling operation of the pallet truck on the cargo.

[0023] In the disclosed embodiment, there are two groups of telescopic pads 1, which are symmetrically distributed on the left and right. The upper side of the telescopic pads 1 is provided with a transverse strip texture structure, which increases the contact friction between the telescopic pads 1 and the bottom of the cargo pallet through the transverse strip texture structure, thereby preventing the cargo pallet from detaching from the telescopic pads 1 due to the moving inertia of the telescopic pads 1, thereby improving the stability of the telescopic pads 1, and the lower side of the telescopic pads 1 is provided with three groups of convex strip structures.

[0024] In the disclosed embodiment, a boss is provided at the center position of the rear side surface of the slide 12, and a through hole structure is provided on the rear side surface of the boss that passes through the front and rear. The outer side surface of the threaded rod 19 is threadedly engaged in the threaded through hole of the boss of the slide 12. The threaded rod 19 drives the two groups of telescopic pads 1 connected by bolts on the upper side of the slide 12 to slide forward and backward, so that the telescopic pads 1 can extend or retract with the cargo.

[0025] In the disclosed embodiment, the fork plate 2 is a U-shaped structure, and a hole groove is provided at the center position of the front side surface of the U-shaped structure of the fork plate 2, and a through hole is provided at the bottom of the hole groove. The convex column structure on the rear side surface of the slide 12 is rotatably connected in the hole groove of the fork plate 2, and the rear end of the threaded rod 19 is rotatably connected in the through hole of the hole groove of the fork plate 2. The upper side surface of the fork plate 2 is provided with six groups of groove structures, and each three groups of grooves are symmetrically distributed on the left and right. The three groups of convex strip structures on the lower side surface of the telescopic pad 1 are embedded in the three groups of grooves of the fork plate 2, so that the telescopic pad 1 can slide directionally along the fork plate 2.

[0026] In the disclosed embodiment, four groups of triangular support plates are provided on the rear side of the baffle 3, and the structural strength of the baffle 3 is enhanced by the triangular structural stability. When the fork plate 2 is flipped and lifted upward, the baffle 3 stably blocks the goods and limits the backward movement of the goods.

[0027] In the disclosed embodiment, the rotating frame 14 is a semi-circular ring structure, and an inner tooth structure is provided on the inner side of the semi-circular ring structure of the rotating frame 14. The gear 20 is meshed and connected to the inner tooth structure of the rotating frame 14. The rotating motor 15 drives the rotating frame 14 meshed with the gear 20 through the rotating rod 16, and the rotating frame 14 drives the support plate 5 to complete the steering of the goods.

[0028] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented.
