Furthermore, two straight wheels are installed at the rear end of the bottom of the trolley chassis, a universal wheel is installed at the front end of the bottom of the trolley chassis, and the two straight wheels and the universal wheel are arranged in an isosceles triangle triangular position.

Furthermore, the number of the positioning grooves is four, two positioning grooves are arranged on each folding arm, and the four positioning grooves are arranged at the positions of four corners of a rectangle.

The utility model discloses has following effect: according to the technical scheme, the U-shaped frame is pushed to lift by additionally arranging the hydraulic push rod on the chassis of the trolley, so that the auxiliary lifting function of the throwing machine is realized. The utility model is not only simple in structure, remove in a flexible way, but also can assist the light transport of staff and shed the machine, laborsaving saving time, safe and reliable.

Drawings

Fig. 1 is a front view of the present invention; fig. 2 is a right side view of the present invention; fig. 3 is a top view of the present invention; fig. 4 is a working state diagram of the present invention.

Description of the drawings: 1. a trolley chassis; 11. a universal wheel; 12. a straight wheel; 2. an outer support tube; 3. an inner support tube; 4, a U-shaped frame; 41. folding the arm; 5. a hydraulic push rod; 6. a support bar; 7. positioning a groove; 8. a throwing machine; 81. adjusting the lead screw; 9. lifting the arm; 10. and (5) hanging the nose.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1-3, two outer supporting tubes 2 are vertically fixed at two ends of a trolley chassis 1 respectively, the four outer supporting tubes 2 are arranged at four rectangular corners, the lower portion of the inner supporting tube 3 is inserted into the outer supporting tubes 2 in a sliding manner, the upper portion of the inner supporting tube 3 is fixed on a folding arm 41 of a horizontal U-shaped frame 4, two ends of the trolley chassis 1 are respectively and vertically hinged with a hydraulic push rod 5, the hydraulic push rod 5 is positioned between the two outer supporting tubes 2 at the same end of the trolley chassis 1, the bottom end of a supporting rod 6 is fixed on a piston rod end of the hydraulic push rod 5, the top end of the supporting rod 6 is hinged on the folding arm 41 of the U-shaped frame 4, and a positioning groove 7 is arranged on the folding arm 41. The hydraulic push rod 5 can push the U-shaped frame 4 to move up and down integrally through the support rod 6, and the outer support pipe 2 and the inner support pipe 3 can play a guiding role in matching sliding.

Two straight wheels 12 are installed at the bottom rear end of the trolley chassis 1, a universal wheel 11 is installed at the bottom front end of the trolley chassis 1, the two straight wheels 12 and the universal wheel 11 are arranged in an isosceles triangle triangular position, and the auxiliary lifting device is convenient to move and steer integrally by the aid of the structure.

The number of the positioning grooves 7 is four, two positioning grooves 7 are arranged on each folding arm 41, the four positioning grooves 7 are arranged at the four corners of a rectangle, and the positioning grooves 7 are matched with the lifting arms 9 on the throwing machine 8 for positioning. As shown in fig. 4, when the throwing machine 8 needs to be moved down, the auxiliary lifting device is moved to the lower part of the throwing machine 8, then the U-shaped frame 4 is lifted through the hydraulic push rod 5 until the positioning groove 7 on the U-shaped frame is just clamped on the lifting arm 9, the adjusting screw 81 is screwed down and the U-shaped frame 4 is continuously lifted, so that the hanging nose 10 on the throwing machine 8 is separated from the tail of the vehicle, then the throwing machine 8 is driven to move to a working road surface area together, the U-shaped frame 4 is finally lowered, the lifting arm 9 is separated from the positioning groove 7, and wheels at the bottom of the throwing machine 8 are in contact with the trolley chassis 1 and are pushed to the road surface. And the process of hanging the spreader 8 to the rear of the vehicle is the reverse of the above-described process.

In the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," and "fixed" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected, and may communicate between two elements. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.
