The oil inlet of the hydraulic cylinder is connected with the pipe end of the oil pipe on the manual hydraulic pump; the telescopic boom is composed of a boom storage tube and a sleeve The boom structure inside the boom storage tube; the hydraulic telescopic rod and the telescopic boom are set in such a way that the piston rod of the hydraulic telescopic rod and the boom of the telescopic boom move in the same direction, and the front end of the boom and the front end of the piston rod pass through the connecting piece connected; the hook is fixed on the bottom surface of the front end of the boom.

Further, two grapples are symmetrically arranged on the bottom surface of the mounting plate; one of the grapples is fixed on the bottom surface of the mounting plate, and the other grapple is fixed on the bottom surface of the mounting plate in a detachable or movably adjustable manner, so that the two grapples The spacing distance can be adjusted to match the width of the handrail of the hydraulic mobile forklift, so that the mounting plate is fixed on the handrail.

Further, the connecting piece is composed of a connecting column and a lifting lug; the connecting column is arranged perpendicular to the boom and its bottom surface is fixed on the top surface of the front end of the boom; It is fixed on the top of the connecting column, and its side wall is fixed to the front end face of the piston rod as a whole, so that the piston rod and the boom move synchronously.

Further, the manual hydraulic pump is fixed on the mounting plate through two fixed pins spaced below the pipe body of the manual hydraulic pump.

Further, the hydraulic telescopic rod is fixed on the telescopic boom through two fixed pins spaced below the pipe body of the hydraulic telescopic rod.

Furthermore, the fixed pin is a trapezoidal platform structure, and a through groove adapted to the outer diameter and shape of the tube body placed on it is opened on the top surface.

Compared with the prior art, the lifting forklift combined accessories are easy to install and easy to operate, and can directly hoist the motor and oil pump with explosion-proof requirements indoors, and the hoisted equipment can be moved directly to the place, reducing the work intensity of the operator, and the operator No more than two people can complete the work; at the same time, the forklift combined parts are easy to disassemble without destroying the structure and function of the mobile forklift.

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the following embodiments in no way limit the present invention.

As shown in Figures 1 and 2, the forklift combined accessories include a manual hydraulic pump 1, a hydraulic telescopic rod 2, a telescopic boom 3 and a hook 4; wherein, the pipe body of the manual hydraulic pump 1 is installed on the operating side of the mobile forklift; The hydraulic telescopic rod 2 and the telescopic boom 3 are installed on the working side of the mobile forklift; specifically,

The manual hydraulic pump 1 is arranged horizontally, and it is fixed on the mounting plate 5 through two fixed pins 6 fixed below the pipe body of the manual hydraulic pump 1 at two intervals;

Wherein, two grabbing hooks are arranged symmetrically on the bottom surface of the mounting plate 5; one of the grabbing hooks is fixed on the bottom surface of the mounting plate, and the other grabbing hook is detachably or movably adjustable and fixed on the bottom surface of the mounting plate, so that the two grabbing hooks The spacing distance is adapted to the width of the pushing handrail of the hydraulic mobile forklift, so that the manual hydraulic pump 1 is fixed on the pushing handrail through the mounting plate 5 during use;

The hydraulic telescopic rod 2 is located above the telescopic boom 3, and it is fixed on the telescopic boom 3 by two fixed pins 6 fixed at two intervals below the tube body of the hydraulic telescopic rod 2;

The hydraulic telescopic rod 2 is composed of a hydraulic cylinder and a piston rod installed in the hydraulic cylinder; the oil inlet of the hydraulic cylinder is connected with the pipe end of the oil pipe on the manual hydraulic pump 1;

The telescopic boom 3 is composed of a boom and a boom storage tube; the inner diameter of the boom storage tube is slightly larger than the outer diameter of the boom, so that the boom is set inside the boom storage tube and can be extended or retracted relative to the boom storage tube ; Hook 4 is fixed on the bottom surface of the front end of the boom;

The hydraulic telescopic rod 2 and the telescopic boom 3 are set in such a way that the piston rod of the hydraulic telescopic rod 2 and the boom of the telescopic boom 3 move in the same direction, and the front end of the boom is connected with the front end of the piston rod through a connecting piece 7; wherein, The boom storage tube of the telescopic boom 3 is detachably fixed on the lifting rod of the hydraulic mobile forklift through the clamp, so that the hydraulic telescopic rod 2 and the telescopic boom 3 are lifted to the specified height with the lifting rod;
