Description

Technical Field

[0001] The utility model relates to the technical field of loader telescopic forks, in particular to a loader telescopic fork with a positioning structure. Background Art

[0002] The loader telescopic fork is an important working device on the loader, mainly used for grabbing, lifting and carrying goods. The loader telescopic fork is mainly composed of fork arms, telescopic mechanisms, lifting mechanisms, locking devices and other parts. The telescopic fork can adjust the length according to needs to adapt to goods of different sizes and shapes. The loader telescopic fork is widely used in the handling and stacking of various goods, especially in logistics, warehousing, construction and mining. It can be used in conjunction with a loader, and the positioning structure is an important part of the loader telescopic fork.

[0003] For example, the Chinese patent "A loader telescopic fork that is easy to adjust" with announcement number CN219279416U includes a loader, a lifting and adjusting mechanism is installed at the front end of the loader, a fixed rod is installed at the movable end of the lifting and adjusting mechanism, and two fixed rods are installed; a telescopic fork, which is installed above the fixed rod, and the telescopic fork is slidably connected to the fixed rod, and guide blocks are provided at the lower ends of both sides of the telescopic fork, and the guide blocks are wrapped around the outside of the fixed rod, and the guide blocks are slidably matched with the fixed rod; an extension plate, which is arranged in grooves on both sides of the telescopic fork, and the extension plate is slidably connected to the telescopic fork, and a transmission rod is fixedly provided on the inner side of the extension plate, and a rack is provided on one side of the transmission rod; a transmission mechanism, which is arranged at the rear end between the fixed rods, and a motor is fixedly installed at the front end of the telescopic fork.

[0004] Although the above-mentioned prior art can realize the use of loader telescopic fork, in actual use, on the one hand, the positioning and adjustment of the loader telescopic fork is not flexible enough. The telescopic fork needs to be disassembled and adjusted according to the different sizes of goods, resulting in the need to adjust the telescopic fork every time different goods are loaded, thereby reducing the working efficiency of the telescopic fork. On the other hand, the telescopic fork is not easy to retract. When the loader is moved when the telescopic fork is not in use, the telescopic fork still remains in a working state, resulting in the loader easily touching the goods during movement, thereby causing damage to the goods. Therefore, it does not meet the existing needs. In this regard, we propose a loader telescopic fork with a positioning structure. Utility Model Content

[0005] The utility model aims to provide a loader telescopic fork with a positioning structure to solve the problems in the above background technology that the positioning and adjustment of the loader telescopic fork is not flexible enough and the telescopic fork is not easy to retract.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a loader telescopic fork with a positioning structure, comprising a mounting plate; and further comprising:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model can adjust the distance between the mounting rods through the screw rod and the first motor. When the telescopic fork needs to be adjusted according to the position of the cargo, the servo motor is first turned on to make the output shaft of the servo motor drive the screw rod to rotate. At this time, the screw rod drives the first fixed rod to move through the external thread. The movement of the first fixed rod drives the mounting rod together with the fixed fork and the telescopic fork body to move, so that the distance between the telescopic fork bodies on both sides is changed to adapt to the positions of different cargoes, thereby making the position adjustment of the telescopic fork body more accurate.

[0017] 2. The utility model can retract the unused telescopic fork through the drive motor and the rotating rod. When the telescopic fork is not in use and the loader needs to be moved, the drive motor is first turned on to make the output shaft of the drive motor drive the rotating rod to rotate. When the rotating rod rotates, the fixed fork and the telescopic fork body fixedly connected thereto are driven to rotate together until the fixed fork is rotated from a horizontal posture to a vertical posture. When the telescopic fork needs to be used, the drive motor is turned on again to make the output shaft of the drive motor drive the rotating rod to rotate again to rotate the fixed fork and the telescopic fork body from a vertical posture to a horizontal posture. At this time, the lower end of the fixed fork contacts the inner wall of the limit cavity and the fixed fork is clamped and fixed, thereby avoiding damage to the cargo when the telescopic fork is not in use and during the movement of the loader.

[0018] 3. The utility model can extend the length of the telescopic fork through the hydraulic telescopic device and the telescopic fork. When the telescopic fork needs to be extended, the hydraulic telescopic device is turned on to extend the telescopic end of the hydraulic telescopic device. When the telescopic end of the hydraulic telescopic device is extended, the telescopic fork body is driven to extend outward. At this time, the limit bars on both sides of the telescopic fork body slide in the telescopic groove until the telescopic fork body moves to a suitable position, so that the length of the telescopic fork body can be changed to adapt to goods of different sizes, thereby improving the adaptability of the telescopic fork to goods of different sizes.
