Description

Technical Field

[0001] This utility model relates to the field of pallet handling vehicle technology, and in particular to a self-unloading pallet truck. Background Technology

[0002] In existing technologies, pallet trucks are logistics handling equipment suitable for heavy-duty and long-term cargo transfer conditions, which can greatly improve cargo handling efficiency and reduce labor intensity. Pallet trucks are small, lightweight logistics devices powered by a hydraulic system. They achieve horizontal transport of goods by inserting pallet forks into the fork holes and can be divided into manual and electric types. Manual types rely on human power to drive the hydraulic system and are suitable for short-distance, light-load operations; electric types are powered by batteries, equipped with AC motors and intelligent control systems, and are suitable for long-distance, heavy-duty handling.

[0003] A search revealed a Chinese patent application with patent number 202421924530.0, which discloses a semi-electric pallet truck. This device uses elastic pins to limit the position of the pallet being carried, thereby ensuring the stability of the pallet truck during pallet transfer. However, in actual use, operators still need to manually operate the device and make actual adjustments to the elastic pins and other structures, which is not conducive to quickly adjusting the position of the pallet truck and improving its transportation efficiency. Utility Model Content

A lateral support plate is fixedly installed at the bottom of the telescopic end of the lifting hydraulic cylinder, and multiple lateral rollers are rotatably installed on the lower surface of the lateral support plate. Two adjustment assemblies are respectively located on both sides of the pallet truck frame. Their main bodies include a hydraulic telescopic rod and a rotating adjustment arm. A rotating connector is fixedly installed at the telescopic end of the hydraulic telescopic rod, and a rotating mounting seat is fixedly connected to the end of the rotating adjustment arm near the hydraulic telescopic rod. The rotating connector is rotatably installed inside the rotating mounting seat.

[0007] As a further improvement of this utility model: a protective baffle is provided on the back of the hydraulic control box, and a protective rubber pad is bonded to the back of the protective baffle.

[0008] As a further embodiment of this utility model: the fixed mounting plate is fixedly installed between the two insert arm brackets of the pallet truck frame, and the lifting hydraulic cylinder is directly controlled by the hydraulic control box.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] A type of self-unloading pallet truck, such as Figures 1 to 4 As shown, the pallet truck includes a pallet truck frame 1, a lateral lifting assembly, and an adjustment assembly. The pallet truck frame 1 is equipped with a hydraulic lifting control pipeline system, and a hydraulic control box 2 is fixedly installed on the top of its front end. The hydraulic control box 2 supplies hydraulic oil to the hydraulic lifting control pipeline system of the pallet truck frame 1 and controls the system. The pallet truck frame 1 and the hydraulic control box 2 constitute a pallet truck. Pallet truck technology is mature and there are many types on the market, so this application will not elaborate on them further.

[0025] Based on the existing pallet truck, a protective baffle 3 is installed on the back of the hydraulic control box 2 and mounted on the top of the pallet truck frame 1. A protective rubber pad 12 is bonded to the back of the protective baffle 3 to protect the pallet and the hydraulic control box 2, thereby improving the safety of the pallet truck.

[0026] The main body of the horizontal lifting assembly is a fixed mounting plate 13. A lifting hydraulic cylinder 14 is fixedly installed at the bottom of the fixed mounting plate 13. A horizontal support plate 15 is fixedly installed at the bottom of the telescopic end of the lifting hydraulic cylinder 14. Roller grooves are provided at the four corners of the lower surface of the horizontal support plate 15. Horizontal rollers 16 are rotatably installed inside the roller grooves.

[0027] like Figure 2 and Figure 3As shown, the fixed mounting plate 13 is fixedly installed between the two insert arm brackets of the pallet truck frame 1 and close to the hydraulic control box 2; the lifting hydraulic cylinder 14 is directly controlled by the hydraulic control box 2, and its extension length is fixed, so that the rollers of the pallet truck frame 1 are off the ground and do not contact the bottom surface of the pallet, which facilitates the lateral movement of the pallet truck frame 1.

[0028] The fixed mounting plate 13 can also be installed at the bottom of the front end of the pallet truck frame 1, and the position of the transverse lifting component can be adjusted according to the center of gravity of the pallet truck.

[0029] Two adjustment components are respectively set on both sides of the pallet truck frame 1. The main body includes a hydraulic telescopic rod 5 and a rotating adjustment arm 8. The tail end of the hydraulic telescopic rod 5 is rotatably mounted with a positioning mounting seat 4, which is fixedly installed on the front end of the side of the pallet truck frame 1.

[0030] The end of the rotating adjusting arm 8 away from the hydraulic telescopic rod 5 is rotatably mounted with a positioning mounting seat 2 7, which is fixedly mounted on the rear end of the pallet truck frame 1 on the same side.

[0031] A rotating connector 6 is fixedly installed at the telescopic end of the hydraulic telescopic rod 5. A rotating mounting base 9 is fixedly connected to one end of the rotating adjusting arm 8 near the hydraulic telescopic rod 5. The rotating connector 6 is rotatably installed inside the rotating mounting base 9.

[0032] The rotating adjusting arm 8 is located on the side away from the pallet truck frame 1 and close to the end of the hydraulic telescopic rod 5. A matching roller frame 10 is fixedly installed thereon, and an auxiliary roller 11 is rotatably installed inside the matching roller frame 10.

[0033] A positioning mounting groove is provided in the middle of the side of the rotating adjustment arm 8. The positioning mounting groove passes through the rotating adjustment arm 8, and a fixing mounting sleeve 17 is fixedly installed at the end of the positioning mounting groove away from the pallet truck frame 1. A cooperating spring 18 is fixedly installed inside the fixing mounting sleeve 17.

[0034] like Figure 1 As shown, at this time, the rotating adjustment arm 8 is in contact with the side of the pallet truck frame 1, and the cooperating spring 18 is in a compressed state. When the hydraulic telescopic rod 5 extends, the elastic force generated by the compression of the cooperating spring 18 will cause the rotating adjustment arm 8 to deflect away from the pallet truck frame 1.

[0035] The hydraulic telescopic rod 5 is supplied with hydraulic oil by the hydraulic control box 2, which also controls its extension and retraction. The hydraulic telescopic rods 5 of the two adjustment components extend and retract synchronously. The specific synchronization method can be referred to the prior art, and will not be described in detail in this application.

[0036] Working principle:

[0037] Please refer to Figures 1 to 4 Assemble the device as shown in the figure;

[0038] When using this device, firstly, as follows Figure 1 (Initial state) The device moves to the bottom of the pallet, so that the two insert arms of the pallet truck frame 1 are inserted into the pre-reserved bearing groove under the pallet truck. Then, the lifting hydraulic cylinder 14 is activated through the hydraulic control box 2. The lifting hydraulic cylinder 14 extends, causing the transverse support plate 15 to descend, so that the transverse roller 16 contacts the ground and the pallet truck frame 1 is lifted off the ground. Then, the hydraulic telescopic rod 5 of the adjustment component is activated, causing the rotating adjustment arm 8 to deflect outward. During the deflection of the rotating adjustment arm 8, the auxiliary roller 11 of one of the adjustment components first contacts the side wall of the bearing groove of the pallet truck. Upon contact, the hydraulic telescopic rod 5 extends continuously. With the cooperation of the lateral roller 16, the pallet truck moves away from the lateral roller 16 until another auxiliary roller 11 contacts the side wall of the bearing groove, completing the positioning of the pallet truck. At this time, the pallet is directly above the pallet truck. Then, the hydraulic control box 2 first controls the hydraulic telescopic rod 5 to retract to the initial state, then controls the lifting hydraulic cylinder 14 to retract to the initial state, then starts the hydraulic lifting control pipeline system to control the pallet truck frame 1 to carry the pallet and lift the pallet off the ground, and then transfers the pallet.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
