Description

Technical Field

[0001] The utility model relates to the technical field of telescopic arm fixing devices, in particular to a telescopic arm forklift telescopic arm assembly process fixing device. Background Art

[0002] A telescopic forklift is a multi-purpose vehicle with a telescopic arm structure and forklift attachments. It has off-road capabilities and can adapt to a variety of work scenarios. The forklift attachments are installed at the connection between the four-section arm head and the attachment quick-change device. Since the installation position of the telescopic arm is higher than the ground, the vertical size of the four-section arm head is larger, which makes the installation and storage of the four-section arm difficult. At the same time, the bottom of the basic arm of the telescopic forklift is a curved structure, and the upper surface of the horse leg and other tooling is generally flat, which cannot support the basic arm well. It is easy to tip over during production and storage, which is not conducive to production safety and efficiency.

[0003] In actual production, sleepers are often used to pad the two sides of the crane arm. However, since the sleepers cannot be fixed, the problem of unstable placement is not completely solved. The vertical dimension of the four-section boom head of the telescopic arm forklift is large, and the telescopic arm needs to be lifted a higher distance during installation. The horse legs of conventional height cannot meet the requirements.

[0004] A device for fixing the arm assembly process of a telescopic forklift disclosed in announcement number CN219094953U comprises a supporting body, a side supporting component and a leg splint component; the supporting body comprises a leg mounting seat, a side supporting mounting seat located above the leg mounting seat and a bottom supporting platform of the arm fixed to the middle part of the top end of the side supporting mounting seat; and when the leg mounting seat sets the device on the leg, the leg mounting seat and the leg are clamped and fixed by the leg splint component; the side supporting component comprises two symmetrically distributed supporting components; the utility model can form support for the side of the telescopic arm whose bottom surface is similar to an arc surface type through the side supporting component with adjustable supporting angle, thereby improving the placement stability of the telescopic arm during storage and assembly, and avoiding lateral tipping of the telescopic arm during storage.

[0005] Although the above patent has achieved support for the side of the telescopic arm with a curved bottom surface, thereby improving the placement stability of the telescopic arm during storage and assembly and preventing the telescopic arm from tipping over laterally during storage; however, the device lacks a buffer component and cannot prevent the telescopic arm from exerting excessive impact force on the device when the user operates improperly during placement, which may damage some small parts of the device.

[0006] Therefore, it is necessary to invent a telescopic arm forklift boom group to fix the process device to solve the above problems. Utility Model Content
