Description

Technical Field

[0001] The utility model belongs to the technical field of lifting and moving devices, and in particular relates to a self-propelled lifting and moving device for large-diameter pipeline construction. Background Art

[0002] In the process of large-diameter pipeline construction, a lifting and moving device is required. At present, the common lifting and moving device mainly installs an electric hoist on the gantry, uses the electric hoist to lift the pipeline for lifting, and sets rollers at the bottom of the gantry for easy movement. However, the prior art still has unstable docking and poor adaptability to pipeline lifting. For example, in a large-diameter pipeline construction self-lifting and moving device with patent number CN217894856U, the electric hoist is fixedly installed at the bottom of the cross frame, and the roller is transferred at the bottom of the support plate. This results in that the roller cannot be effectively fixed relative to the ground when the pipeline is docked, resulting in poor stability during pipeline docking construction. At the same time, the spacing between the two relatively arranged electric hoists is certain. When the size of the hoisted pipeline is greater than or less than the spacing, the traction rope of the electric hoist cannot remain vertical when it is pulled. In order to ensure that the required traction force is provided to the pipeline, the inclined traction rope needs to increase the output power of the electric hoist, which leads to an increase in the energy consumption of the electric hoist. Therefore, there are certain usage defects. Utility Model Content

When the ground nail 4 abuts against the ground, a pair of supporting mechanisms are fixed to the ground.

[0038] A crossbeam 5 is fixedly connected between a pair of support rods 1;

[0039] A pair of sliders 6 are arranged relatively on the cross beam 5 and slidably cooperate with the cross beam 5. A second driving member is provided on the cross beam 5. The driving ends of the second driving member are respectively connected to the pair of sliders 6. The pair of sliders 6 are moved closer to or away from each other through the second driving member. The sliders 6 are used to install the electric hoist 7.

[0040] The utility model drives the fixing rod 3 to rise and fall relative to the supporting plate 11 through the first driving member, and drives the ground nail 4 to rise and fall, and utilizes the ground nail 4 to abut against the ground to limit and fix the roller 2, so that when the pipelines are docked, the grounding stability of a pair of supporting mechanisms is improved, and the docking effect is guaranteed. In addition, a second driving member is arranged on the crossbeam 5, and the driving end of the second driving member is connected to a pair of sliders 6. The second driving member drives the pair of sliders 6 to move closer to or away from each other, thereby realizing the adjustment of the distance between the pair of electric hoists 7, ensuring that when hoisting different pipelines, the hoisting rope 8 of the electric hoist 7 can maintain a vertical state, reducing the extra energy consumption of the electric hoist 7, and improving the use effect.

[0041] Furthermore, it also includes:

[0042] The support plate 11 is fixed to the bottom end of the support rod 1, and the fixing rod 3 passes through the support plate 11 and rises and falls relative to the support plate 11;

[0045] By fixing the motor plate 10 on the support plate 11, the drive motor 9 is fixed on the motor plate 10, and the output shaft of the drive motor 9 is fixedly connected to the roller 2, so as to drive the roller 2 to rotate and realize the movement of a pair of support mechanisms.

[0046] Furthermore, it also includes:

[0047] The worm wheel 12 is rotatably engaged on the support plate 11. One end of a threaded sleeve 15 is fixedly connected to the axis of the worm wheel 12.

During the rotation of the worm gear 12, the rotating rod 14 rises and falls relative to the threaded sleeve 15, thereby driving the fixed rod 3 to realize the lifting and lowering adjustment of the ground nail 4.

[0058] The second motor 20 drives the gear 21 to rotate, and the gear 21 extends into the groove and engages with a pair of tooth plates 22 respectively, thereby driving the pair of tooth plates 22 to move closer to or away from each other, and then the tooth plates 22 and the slider 6 move closer to or away from each other.

[0059] Furthermore, the slider 6 is an L-shaped structure, the long side of the slider 6 is arranged on the bottom surface of the beam 5, and the two electric hoists 7 are located on the same axis.

[0061] Furthermore, a second limiting groove is formed on the cross beam 5 , a second limiting block 23 is fixedly connected to the side wall of the sliding block 6 , and the second limiting block 23 is slidably connected to the second limiting groove.

[0062] It can be understood that the length of the second limit groove is smaller than the length of the beam 5, and the center is located in the middle of a pair of support rods 1. The second limit fastener is abutted against the two ends of the second limit groove to limit the movement range of the slider 6 and ensure the meshing state of the tooth plate 22 and the gear 21.

[0063] The working process of this embodiment is as follows:

[0064] According to the diameter of the pipeline, the second motor 20 is started to drive the gear 21 to rotate, and the pair of sliders 6 are slid to adjust the spacing through the engagement of the gear 21 with a pair of racks, so that the spacing between the two electric hoists 7 corresponds to the diameter of the pipeline, the pipeline is placed on the lifting rope 8, the pipeline is lifted by the electric hoist 7, and the drive motor 9 is started to drive the roller 2 to move. After reaching the pipeline construction position, the first motor 18 is started to rotate the worm 13 and the worm wheel 12, and the threaded sleeve 15 and the rotating rod 14 are used to extend the fixing rod 3 out of the support plate 11, and the ground nail 4 is made to abut against the ground to fix the overall lifting and moving device.
