[0002] In modern urban construction, the laying of underground pipelines is an important engineering task. Among them, rectangular jacking pipe sections, as a common pipeline structure, are widely used in municipal projects such as water supply, drainage, and gas. In order to ensure the safe and efficient construction of pipelines, special lifting devices are required to install and transport these pipe sections.

A pair of symmetrically arranged lifting arms are symmetrically arranged on the left and right sides of the crossbeam. The lifting arms are L-shaped structures, and the crossbeam and the lifting arms on each side are fixedly connected by bolts to form a solid integrated structure; a fixing bolt through hole is respectively provided at the L-shaped vertical end and the L-shaped horizontal end of the lifting arm on each side to insert a steel rod to firmly connect the lifting arm to the turning hole and lifting hole on the rectangular top pipe section. The utility model lifting structure device belongs to a rigid lifting device, which improves the stability and safety of large-section rectangular pipe sections during lifting, and plays a positive role in safe construction.

[0027] In this embodiment, the bottom sides of the four hanging rings 12 are welded to the top side of the adjusting box 11, one side of the bracket 14 is fixedly connected to the side of the adjusting box 11, one end of the bidirectional screw 16 passes through the slot opened on one side of the adjusting box 11 and is fixedly connected to the output end of the servo motor 15, and the other end of the bidirectional screw 16 is rotatably connected to the side of the inner surface of the adjusting box 11 away from the servo motor 15, and the two different threaded parts on the outer surface of the bidirectional screw 16 are threadedly connected with the adjusting blocks 17, and the bottom sides of the two adjusting blocks 17 are fixedly connected with the clamping plates 18; welding the hanging ring 12 and the adjusting box 11 together can ensure that the connection point is firm and reliable, can withstand large external forces and vibrations, and reduce the risk of breakage and falling off of the connection point; fixing the bracket 14 to one side of the adjusting box 11 can ensure that the two The connection between the two adjusting blocks 17 is firm and will not loosen or fall off, so that the bracket 14 can provide effective support for the servo motor 15. The two adjusting blocks 17 are fixedly connected to one side of the bottom with a clamping plate 18, which can achieve a firm connection and ensure that the clamping plate 18 will not loosen or fall off during the clamping process of the rectangular pipe section body 114. When the staff needs to hoist the rectangular pipe section body 114 of different sizes, first adjust the distance between the two clamping plates 18 according to the size of the rectangular pipe section body 114, and start the servo motor 15. When the servo motor 15 is started, it will drive the bidirectional screw 16 to rotate, thereby changing the position of the two adjusting blocks 17. At the same time, the spacing between the clamping plates 18 is also adjusted accordingly to obtain a spacing suitable for the size of the rectangular pipe section body 114.

[0028] A micro forward and reverse motor 19 is fixedly connected to one side of the top of the two clamps 18, one end of the one-way screw 110 passes through the slot opened on the top of the clamp 18 and is fixedly connected to the output end of the micro forward and reverse motor 19, the other end of the one-way screw 110 is rotatably connected to the side of the inner surface of the clamp 18 away from the micro forward and reverse motor 19, the outer surface of the one-way screw 110 is threadedly connected to the inner wall of the thread groove opened by the adjusting member 112, the two ends of the slide rod 111 are respectively fixedly connected to the two sides of the inner surface of the clamp 18, the outer surface of the slide rod 111 is slidably connected to the inner wall of the slot opened by the adjusting member 112, and the two adjusting members 112 are opposite to each other. The two sides are fixedly connected with fixed steel pipes; among them, the micro forward and reverse motor 19 is located in the middle part of the recess at the bottom of the adjusting block 17, and the two ends of the sliding rod 111 are fixedly connected to the two sides of the inner surface of the splint 18 respectively, which can ensure that the sliding rod 111 will not fall off and loosen from the inner surface of the splint 18 when subjected to external force. At the same time, the shape and size of the slot opened by the adjusting member 112 match the sliding rod 111. Therefore, when the adjusting member 112 moves up and down, the slot can fit tightly on the sliding rod 111 to form a stable guide channel, so that the movement trajectory of the adjusting member 112 can be more accurate and stable.

[0029] Example 2

[0030] like Figure 1, Figure 4 As shown, the auxiliary mechanism 2 includes a support base 21 , and the support base 21 is welded to one side of the bottom of the two clamping plates 18 , and an anti-slip pad 22 is fixedly connected to one side of the bottom of the two support bases 21 .

At the same time, when the splint 18 is lowered close to the ground, the support base 21 will protect the bottom of the splint 18 to avoid wear and damage caused by the splint 18 contacting the ground. When the anti-slip pad 22 provided at the bottom of the support base 21 can ensure that the splint 18 can stand upright stably when the base contacts the ground, avoiding sliding and shaking of the splint 18 due to uneven ground.

At the same time, the support base 21 also shares the weight applied by the rectangular pipe section body 114 to the fixed steel pipe, which helps to protect the structural integrity of the fixed steel pipe and extend its service life.

[0032] Working principle:

[0033] like Figure 1 - Figure 4 As shown, when the staff needs to hoist the rectangular tube body 114 of different sizes, first adjust the distance between the two clamping plates 18 according to the size of the rectangular tube body 114, and start the servo motor 15. When the servo motor 15 is started, it will drive the bidirectional screw 16 to rotate, so as to change the position of the two adjustment blocks 17. At the same time, the spacing between the clamping plates 18 is also adjusted accordingly to obtain a spacing suitable for the size of the rectangular tube body 114. However, the hoisting holes on both sides of the rectangular tube body 114 will be opened at different positions according to their height. At this time, the staff adjusts the rectangular tube body 114. After adjusting the spacing of the section body 114, it is necessary to find the position of the fixed steel rod 113 and the lifting hole. The micro forward and reverse motor 19 can be started. When the micro forward and reverse motor 19 is started, the adjusting member 112 will move, and the slot opened in the adjusting member 112 will slide on the slide bar 111. When the adjusting member 112 is adjusted to the specified position, the fixed steel rod 113 will maintain the same horizontal height with the lifting holes on both sides of the rectangular tube section body 114. Then, the servo motor 15 is started to clamp the clamping plate 18 inward, so that the fixed steel rod 113 is inserted into the lifting holes opened on both sides of the rectangular tube section body 114, thereby completing the lifting work.
