[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] Reference Figures 1 to 4As shown, this embodiment discloses a pipeline lifting device, including: a mounting plate 1, a lifting device, a stabilizing device, an adjusting device, two mounting seat groups (the lifting device can also be equipped with more than two mounting seat groups, and two are used as an example for description in this embodiment) and two buckling devices (the lifting device can also be equipped with more than two buckling devices, and two are used as an example for description in this embodiment); the lifting device includes a chassis 303 and an adjusting plate 302 located on the chassis 303, and the chassis 303 and A through hole for the hook to pass through is formed between the adjusting disks 302, and the chassis 303 is rotatably connected to the mounting plate 1 (specifically, a hanging hole 201 is provided on the mounting plate 1, and the hanging device passes through the hanging hole 201 and is rotatably connected to the mounting plate 1); both sides of the adjusting disk 302 are connected to the chassis 303 by bolts 301, and the bolts 301 are rotatably connected to the adjusting disk 302, and the bolts 301 are threadedly connected to the chassis 303 (in order to ensure the firmness of the connection between the adjusting disk 302 and the chassis 303, Both sides of the adjusting disk 302 are connected to the chassis 303 by at least two bolts 301); the stabilizing device includes a positioning block 405, a support rod 406 and an adjusting block 402; the positioning block 405 is fixed to the top of the adjusting disk 302, and the left and right sides of the positioning block 405 are respectively provided with protrusions, and the support rod 406 is movably connected between the two protrusions through a pin; the above-mentioned adjusting block 402 is sleeved on the support rod 406 and can slide up and down or be fixed along the support rod 406 (specifically, the adjusting block 402 is moved along the support rod 406). The support rod 406 slides up and down, and is fixed to the support rod 406 by bolts 301 when sliding to a suitable position). The bottom of the support rod 406 is rotatably connected to a top block 403, and the top block 403 and the front and rear sides of the positioning block 405 are connected with springs 404; the two mounting seat groups are fixedly arranged at the bottom of the mounting plate 1, and each mounting seat group includes two mounting seats 203 respectively arranged on both sides of the bottom of the mounting plate 1; each snap-fit ​​device is rotatably arranged under the mounting plate 1 through a mounting seat group. In the process of lifting the pipeline, the pipeline lifting equipment can adapt to hooks of different sizes by rotating the lifting device, so that it can be adaptively lifted, and in this process, the adjustment block 402 of the sliding stabilizing device can be used to support it inside the hook, so that the top of the stabilizing device and the top of the inner ring of the hook are supported, so that when the pipeline is lifted, the lifting and sliding of the equipment are stabilized according to the changes in height and angle to avoid shaking over a long distance. The utility model hoists the pipeline by means of the pipeline hoisting equipment, which greatly improves the adjustability of the equipment hoisting, and improves the hoisting stability of the equipment by means of the multifunctional integrated hoisting method, thereby improving the working efficiency of the equipment.

[0037] Specifically, during the process of hoisting the pipeline, the bolt 301 is rotated. Since the bolt 301 and the chassis 303 are in a threaded connection, the bolt 301 is rotated to make it rise and fall on the chassis 303. Since the bolt 301 and the adjusting disk 302 are in a rotational connection, the adjusting disk 302 is driven to rise and fall relative to the chassis 303 (that is, when the bolt 301 is rotated, the bolt 301 rises or falls relative to the chassis 303, driving the adjusting disk 302 to rise or fall; specifically, the upper part of the bolt 301 is not threaded, and the outer side of the upper part has a flange, and a limiting hole matched with the flange is opened in the adjusting disk 302, and the flange can be rotated in the limiting hole, and the adjusting disk 302 is driven to rise or fall through the flange), so as to adjust the inner diameter of the lifting ring, thereby avoiding frequent replacement of the lifting ring in the urban pipe gallery; the lifting device greatly improves the adjustability of the equipment, and the threaded connection method improves the stability of the equipment adjustment, thereby improving the working efficiency of the equipment. In addition, the sliding adjustment block 402 is made to slide on the support rod 406. After sliding to an appropriate length, it is supported in contact with the inner diameter top of the hook, and the adjustment block 402 is fixed by rotating the screw 401. In this process, when the pipeline swings with the change of height and crane arm angle, the support rod 406 rotates on the positioning block 405 accordingly. The support rod 406 and the positioning block 405 are in a hinged state, and the swing of the support rod 406 drives the top block 403 rotatably connected thereto to slide in the groove in the positioning block 405. The springs 404 on both sides are used for buffering during sliding, and the top block 403 and the support rod 406 are rotatably connected. Therefore, when the hook is hoisted, the hook is inserted into the hole connecting the adjustment disk 302 and the chassis 303. When the hook is at the bent hook position and the adjustment disk 302 is hoisted, the position of the adjustment block 402 is adjusted by rotating the screw 401, and the equipment is stabilized by the bottom hook upper support.

[0038] The stabilization of the stabilizing device greatly improves the swing stability of the hoisting. The sliding of the spring 404 improves the stability of the equipment. A damper can be provided for the spring 404 to prevent the problem of too long a swing cycle or to replace the spring 404 with poor rebound performance.

[0039] Specifically, each of the above-mentioned buckling devices includes two arc rods 501; the two arc rods 501 are rotatably connected to the two mounting seats 203 of the mounting seat group, and the ends of the two arc rods 501 that are not connected to the mounting seats 203 are telescopically connected to the slider 504; and a connecting device is connected between each arc rod 501 and the slider 504 arranged in the arc rod 501, and the connecting device includes a connecting rod 502 and a hinge rod 503, one end of the connecting rod 502 is rotatably connected to the arc rod 501, and the other end is rotatably connected to the hinge rod 503, and the end of the hinge rod 503 that is not connected to the connecting rod 502 is rotatably connected to the slider 504; the ends of the two sliders 504 away from the arc rod 501 are each provided with a connecting buckle 505, and the connecting end of each connecting buckle 505 is a connecting ring, and the connecting ends of the connecting buckles 505 of each buckling device are connected together by a pin 505. By sliding the slider 504 of the buckling device, it can be extended to a sliding adapted length, so that pipes of different sizes can be fitted and clamped, and the sliding adjustment device can be used to support and stabilize the top of the pipe.

[0040] Specifically, the sliding block 504 is slid and extended in the corresponding arc rod 501, and the connecting rod 502 and the hinge rod 503 connected thereto are rotated to position and extend the slider 504. The slider 504 can slide out of the corresponding slot to clamp a pipe with a larger outer diameter. The connecting rod 502 and the hinge rod 503 are equipped with screws 708 and other fastening components to fix the position of the slider 504. The arc rod 501 and the connecting rod 502, as well as the connecting rod 502 and the hinge rod 503, are fixed and cannot rotate by the screws 708, so as to fix the position of the slider 504. Slide to the appropriate position After being placed, the connecting ends of the bottom connecting buckle 505 are matched, and the pin 505 is fixed by inserting the pin 505. The connecting buckle 505 is pulled in the opposite direction with the supporting force of the pipeline to fix the pin 505. In the actual lifting process, the force when the pin 505 is inserted is relatively loose, and the connecting buckle 505 is opened by the actual downward thrust of the pipeline to fix the pin 505. The fastening device is used to greatly improve the stability of the equipment fastening. The connection and deployment of the equipment are improved by the hinged fixation of the connecting rod 502 and the hinge rod 503.

[0041] It should be noted here that when the pipe is adjustably clamped, since the arc rod 501 and the connecting buckle 505 are rotatably connected, the arc rod 501 and the mounting plate 1 are also rotatably connected. The actual adjustment method is that the arc rod 501 opens, and the connecting buckle 505 moves downward as the diameter increases.

[0042] In the embodiment of the utility model, the adjustment device includes a screw rod 601 and a stop block 602; the screw rod 601 is threadedly connected to the bottom of the mounting plate 1, and the stop block 602 is fixed to the bottom end of the screw rod 601; specifically, the mounting plate 1 is provided with a screw hole 202, and the screw rod 601 of the adjustment device passes through the screw hole 202 and is threadedly connected to the mounting plate 1. The screw rod 601 is rotated to move on the mounting plate 1, and the stop block 602 and the corresponding pipeline are driven to support during the movement, which solves the problem that the clamping equipment of the smaller pipeline is larger and difficult to fix; the stop block 602 can be equipped with friction and protective materials such as rubber pads to protect the surface wall of the pipeline while increasing friction and preventing the pipeline from sliding.

[0043] The pipe is clamped by the adjusting device, which greatly improves the stability of the equipment clamping. The stability of the equipment clamping is improved by threaded fastening.

In this process, the output end of the auxiliary device is pulled to make it adaptively buckle according to the length of the pipeline, and after buckling, a triangular stable structure is formed with the connecting end of the auxiliary device and the clamping end of the pipeline; specifically, the wire rope 701 is pulled to make it extend on the rotating shaft 702, and after extending to an appropriate length, the position of the rotating shaft 702 is fixed by the knob 703, and the upper clamping plate 706 and the lower clamping plate 709 are fitted with the outer wall and the inner wall of the pipeline to clamp the top of the pipeline, and the upper clamping plate 706 is slid for adjustment to make the clamping tighter, and fixed by turning the screw 708; in this process, friction and stabilizing materials such as rubber pads can be provided on the clamping plate, and after extending to an appropriate length, a triangular clamping state is formed with the lower position of the pipeline through the height of the support frame 704, so as to stabilize it; and the wire rope 701 is arranged by the wire arrangement plate 705 to avoid its messy entanglement, and the rotating equipment such as motors are also provided to improve the automation level of the equipment;
