[0031] The clamping and grabbing mechanism grabs the bundled rod goods in turn, and then lifts them in turn through the lifting mechanism, so that multiple bundles of rod goods can be grabbed at one time for transportation.

[0032] The driving mechanism includes a motor drive box 15 fixedly mounted on the outer surface of the T-shaped frame 3 away from the U-shaped pipe frame 4, a screw rod 19 is fixedly arranged at the driving end of the motor drive box 15, and the end of the screw rod 19 away from the motor drive box 15 is rotatably matched with the U-shaped pipe frame 4, and the slide 5 is threadedly sleeved on the outside of the screw rod 19;

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, after the motor drive box 15 is started, it can drive the screw rod 19 to rotate, so that the slide 5 threadedly matched with the screw rod 19 can move outside the U-shaped pipe rack 4, thereby controlling the use position of the external structure of the slide 5.

[0034] The lifting mechanism includes a first hydraulic cylinder 6 fixedly mounted inside the slide 5, a reinforcement rod is installed through the L-shaped frame 9, the telescopic end of the first hydraulic cylinder 6 is connected to the upper surface of the reinforcement rod, and a guide rod 12 is fixedly arranged on the upper surface of the L-shaped frame 9 and away from the first hydraulic cylinder 6.

[0037] like Figure 4 , Figure 5 and Figure 8 As shown, the clamp arm 10 can rotate with the same amplitude on the outside of the clamp shaft 18 in coordination with the extension and retraction of the second hydraulic cylinder 7. When the second hydraulic cylinder 7 extends outward, the clamp seat 21 and the universal ball 35 can slide downward on the outside of the corresponding clamp arm 10. The clamp seat 21 fits on the outside of one side of the clamp arm 10, and the universal ball 35 inside the clamp seat 21 rolls and fits with the outer surface of the clamp arm 10 on the side away from the clamp seat 21, so that the clamp arm 10 can achieve the function of gathering and clamping.

[0038] The pushing mechanism includes a fixed block 23 fixedly arranged inside the mounting seat 22 and located between the two connecting rods, a third hydraulic cylinder 24 is fixedly arranged on one side of the outer surface of the fixed block 23, and the telescopic end of the third hydraulic cylinder 24 is connected to the outer surface of the lifting mechanism. The lifting mechanism includes a fixed shell 16 fixedly installed at the telescopic end of the third hydraulic cylinder 24, and sliding shells 27 are slidably installed at both ends of the fixed shell 16. The outer surfaces of the ends of the two groups of sliding shells 27 away from each other are both provided with connecting mechanisms, and the lower surfaces of the two groups of sliding shells 27 are both fixedly arranged with fixed plates 31, and the outer surfaces of the two fixed plates 31 are both provided with circulating lifting mechanisms;

[0039] like Figure 5 and Figure 6 As shown, under the connection of the fixed block 23, the third hydraulic cylinder 24 can drive the fixed shell 16 to move closer to or away from one end of the clamp arm 10. After the clamp arm 10 has clamped the bar-shaped cargo, the circulating lifting mechanism can be supported under one end of the bar-shaped cargo.

[0040] The circulating lifting mechanism includes a plurality of rotating shafts 30 rotatably mounted inside a fixed plate 31, the plurality of rotating shafts 30 are arranged vertically equidistantly from top to bottom, a belt 13 is commonly sheathed outside the plurality of rotating shafts 30, a rotating motor 11 is disposed at one end of the rotating shaft 30 located below, the rotating motor 11 is fixedly connected to the fixed plate 31, a plurality of groups of supporting members are disposed on the outer surface of the belt 13, the plurality of groups of supporting members include a card shell 33 fixedly mounted on the outer surface of the belt 13 and close to the middle, an assembly sleeve 34 is fixedly mounted inside the card shell 33, a cross bar 29 is inserted inside the assembly sleeve 34, and both sides of the cross bar 29 are provided with ascending plates 32;

[0041] like Figure 6 and Figure 7 As shown, the rotating motor 11 can cause the rotating shaft 30 near the bottom to rotate, thereby driving the belt 13 to rotate. The belt 13 will cause the cross bar 29 on the outer surface to circulate and transport. When the assembly set 34 and the clamping shell 33 are clamped, the cross bar 29 can be rotated to the bottom of the stick-shaped goods, and the stick-shaped goods can be lifted at the lower end, so that the clamping arm 10 can transport multiple bundles of sorted stick-shaped goods in sequence.

[0042] A support rod 8 is vertically installed on the lower surface of the slide 5 and near the middle. A slider 14 is fixedly installed at the lower end of the support rod 8. The slider 14 slides outside the slide 2.

[0043] like Figure 1 and Figure 2 As shown, in order to lift the slide 5 to move upward and drive the rod cargo to move, a support rod 8 and a slider 14 are set on the lower surface of the slide 5 to cooperate with the movement of the slide 5, thereby enhancing the stability of the slide 5 when moving.

[0044] The connection mechanism includes a support block 25 fixedly arranged on the outer surface of one end of the sliding shell 27, a fixed rod 26 is fixedly inserted inside the support block 25, and the two fixed rods 26 are connected by a two-way telescopic cylinder 36, and the middle of the two-way telescopic cylinder 36 is fixedly arranged on the upper surface of the fixed shell 16 through a fixed sleeve positioning plate 28;

[0045] like Figure 6 As shown, the support block 25 and the fixed rod 26 are arranged at one end of the sliding shell 27, which can facilitate the driving of the two-way telescopic cylinder 36, so that the sliding shell 27 can move flexibly, thereby adjusting the distance between the fixed plate 31 and the belt 13, and better cooperating with the clamping arm 10 to grab the rod cargo. Through the positioning plate 28, the two-way telescopic cylinder 36 can be fixedly set above the fixed shell 16 for use.

[0046] Working principle: When the four-way vehicle body 1 transports the bundled rod-shaped goods to the transfer vehicle, the motor drive box 15 drives the slide 5 to slide outside the screw rod 19 and the U-shaped pipe rack 4, so that the L-shaped rack 9 can move to the top of the rod-shaped goods. With the telescopic movement of the first hydraulic cylinder 6, the L-shaped rack 9 and the lower end mounting seat 22 and other components are close to the top of the rod-shaped goods. Driven by the cross-arranged second hydraulic cylinder 7, the two groups of clamping arms 10 are controlled to expand, so as to grab the bundled rod-shaped goods. In order to make the secondary grabbing of the rod-shaped goods more stable, when the two groups of clamping arms 10 are gathered together, the bundled rod-shaped goods are pushed to the inside of the two groups of clamping arms 10. At this time, under the telescopic drive of the third hydraulic cylinder 24, the fixed shell 16 and the two fixed plates 31 move from one end to the end of the rod-shaped goods. At the same time, the two-way telescopic cylinder 36 is driven by The two fixing rods 26 are driven away from each other so that the sliding shell 27 can drive the fixing plate 31 away from each other. Then, after the clamping arm 10 has grabbed the goods, the two fixing plates 31 are urged to approach each other, and the corresponding rotating motor 11 is started, so that the belt 13 rotates outside the multiple rotating shafts 30, and the multiple belts 13 circulate and transport the corresponding cross bars 29 and the ascending plates 32 to the lower end of the bundled rod goods, and then during the transportation process, the bundled rod goods are lifted to the upper inside of the two sets of clamping arms 10. Under the support of the ascending plates 32, the rod goods are suspended between the two sets of clamping arms 10, and then the two sets of clamping arms 10 grab the later bundled rod goods, and operate in sequence as above, thereby ensuring that the two sets of clamping arms 10 can grab multiple strands of bundled rod goods to the transfer vehicle at one time during transportation, thereby enhancing the operability and practicality of the traditional four-way vehicle body 1.

[0047] The above shows and describes the basic features, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only the features of the present invention.
