[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0019] like Figure 1-Figure 10 The cement culvert stacking and insertion device shown in the figure comprises a cross frame 1, the lower surface of the cross frame 1 is slidably connected to two wheel frames 13, a distance adjustment mechanism is arranged between the two wheel frames 13, a connecting hook 17 is fixedly connected to the lower surface of the wheel frame 13, and two connecting ropes 18 are fixedly connected to the lower surface of the connecting hook 17, and a convex block 19 is fixedly sleeved at the lower end of the lower outer surface of the two connecting ropes 18, and the two convex blocks 19 are connected to contact plates 24 on the adjacent sides through elastic mechanisms, and the lower ends of the two connecting ropes 18 are fixedly connected to a hanging column 20, and the contact plate 24 is located above the hanging column 20, and connecting columns 6 are fixedly connected to the lower sides of the lower surface of the cross frame 1, and the lower ends of the two connecting columns 6 are movably connected to the bottom frame 11, and a lifting mechanism is arranged between the bottom frame 11 on one side and the connecting column 6, and wheels 12 are respectively installed at the front and rear ends of the lower surface of the bottom frame 11.

[0020] The front and rear inner walls of the wheel frame 13 are rotatably connected with rollers 15, and the lower side of the rollers 15 contacts the inner bottom surface of the horizontal frame 1. When the wheel frame 13 moves, the rollers 15 will move along the inner bottom surface of the horizontal frame 1, ensuring that the wheel frame 13 can move smoothly.

[0021] The pitch adjustment mechanism includes a reinforcement seat 2 fixedly connected to the middle of the front surface of the horizontal frame 1, and end seats 4 are fixedly connected to both sides of the front surface of the horizontal frame 1. The two end seats 4 rotate together with the inner side of one reinforcement seat 2, and a screw rod 3 is passed through. One end of the screw rod 3 is fixedly connected to the output shaft of the motor 5, and the motor 5 is fixedly installed at one end of the horizontal frame 1. The wheel frame 13 is threadedly connected with the screw rod 3. Through the operation of the motor 5, the screw rod 3 rotates, thereby controlling the two wheel frames 13 to move closer or farther from each other.

[0022] The front surface of the wheel frame 13 is fixedly connected with a sleeve seat 14, and the screw rod 3 is threaded through the inner side of the sleeve seat 14. The threads opened on the surface of the screw rod 3 are symmetrical on both sides, ensuring that when rotating, the two sleeve seats 14 move closer to or away from each other.

[0023] The elastic mechanism includes two sleeve blocks 23 fixedly connected to one side of the contact plate 24, and the two sleeve blocks 23 are respectively slidably sleeved on the front and rear edges of the convex block 19, and the end of the convex block 19 away from the contact plate 24 is fixedly connected to the end plate 25, and the front and rear ends of one side surface of the end plate 25 slide through the sliding rod 27, and one end of the two sliding rods 27 is respectively fixedly connected to the side ends of the sleeve blocks 23, and the other ends of the two sliding rods 27 are commonly fixedly connected to the limit plate 26, and the outer surface of the sliding rod 27 is sleeved with a compression spring 28, and the compression spring 28 is located between the end plate 25 and the sleeve block 23. The limit plate 26 plays a limiting role, preventing the end of the sliding rod 27 from being separated from the end plate 25 under the elastic force of the compression spring 28. The compression spring 28 provides elastic force so that the contact plate 24 can be reset when not pushed, ensuring that when the suspension column 20 is inserted into the port of the tube body 30, the contact plate 24 can contact the port of the tube body 30 as early as possible, effectively preventing the connecting rope 18 from contacting the port of the tube body 30, and also serving as an indicator to guide the entry height of the suspension column 20.

[0024] One end of the sleeve block 23 away from the contact plate 24 is fixedly connected with a thickening block 29, and one end of the sliding rod 27 is fixedly connected to the side surface of the thickening block 29. The thickening block 29 improves the structural strength and prevents the problem of the connection between the section of the sliding rod 27 and the sleeve block 23 being unstable.

[0025] The lower end of the connecting column 6 is fixedly connected with an upper connecting plate 7, the upper end of the bottom frame 11 is fixedly connected with a lower connecting plate 9, and the lower surface of the upper connecting plate 7 is fixedly connected with a plurality of guide rods 8, which slide through the outer surface of the lower connecting plate 9. In this way, the movable connection between the connecting column 6 and the bottom frame 11 is realized.

[0026] The upper surface of the lower connecting plate 9 is fixedly connected with a lifting cylinder 10, and the telescopic end of the lifting cylinder 10 is fixedly connected to the lower surface of the upper connecting plate 7. By controlling the telescopic movement of the lifting cylinder 10, the up and down movement of the cross frame 1 is controlled.

[0027] A plurality of transverse connecting rods 21 are fixedly connected to both side surfaces of the suspension column 20, and a miter connecting rod 22 is fixedly connected between the upper surface of the transverse connecting rod 21 and the side surface of the convex block 19. The transverse connecting rod 21 and the miter connecting rod 22 form a triangular frame structure, which can improve the strength of the suspension column 20.

[0028] By pushing the whole, with the help of the wheels 12, the whole can move in the front-rear direction, and the cross frame 1 moves up and down by the extension and contraction of the lifting cylinder 10, and stops when the suspension column 20 approaches the two ends of the tube body 30. Then the motor 5 is controlled to operate, so that the screw rod 3 rotates, and then the wheel frames 13 on both sides move closer to each other, and the suspension columns 20 on both sides are close to each other. When the contact plate 24 is attached to the end of the tube body 30, it is pushed, so that the sleeve block 23 and the sliding rod 27 are synchronously moved laterally, squeezing the compression spring 28. After moving, the suspension column 20 is hung in the end of the tube body 30, and the state is as follows: Fig.10 As shown, it should be noted that Fig.10 The tube body 30 in the drawing is in a cross-sectional state, and then the motor 5 is stopped, and the lifting cylinder 10 is controlled to extend. After the tube body 30 is lifted, the cross frame 1 is pushed to move to the specified position, and then the lifting cylinder 10 is contracted, so that the tube body 30 is lowered to the gap between the stacked tube bodies 30 to complete the interlaced stacking and make full use of the stacking space. The tube body 30 can be automatically suspended, lifted and lowered. When hanging and lowering, the user does not need to assist in operating at the end of the tube body 30, which is convenient to use.

[0029] In the above stacking, the contact plate 24 will contact the port of the tube body 30, playing an effective protective role, preventing the metal connecting rope 18 from scratching the edge of the port of the tube body 30, avoiding damage problems.

[0030] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention.
