Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground pipeline construction technology, and more specifically, to a lifting device for an underground pipeline construction drilling rig. Background Technology
[0002] Trenchless pipeline laying is a method of laying underground pipelines without excavating the surface. Compared with traditional trenching pipeline laying, trenchless pipeline laying has advantages such as not affecting traffic and not polluting the environment. In many cases, its construction cycle, cost and safety are superior to the traditional trenching method.
[0003] A search revealed that utility model patent CN220336829U discloses a drilling rig for underground pipeline construction, including a lifting mechanism, a drilling mechanism, and a support mechanism. The lifting mechanism includes a base, with a first shaft movably sleeved on the left end of the base and a sliding groove on the right end of the base. A second shaft is engaged inside the sliding groove. A scissor arm is connected to the top of the first and second shafts, and a top seat is slidably mounted on the top of the scissor arm. The drilling mechanism includes a frame mounted on top of the top seat. This underground pipeline construction drilling rig, by setting up a lifting mechanism, allows for adjustment of the height of the lifting mechanism by using a hydraulic cylinder to move the second shaft back and forth before drilling, facilitating accurate adjustment of the drilling position. It eliminates the need for support structures, making it more convenient to use. However, the above-mentioned patent still has the following shortcomings: Although the height of the drilling rig can be adjusted by using the scissor arm, when the drilling rig is raised to the highest point, the base and the top seat are suspended in the air, which affects the stability of supporting the top seat and the drilling rig. In addition, it is not convenient to move the drilling rig or to fix the device. Therefore, we propose a lifting device for underground pipeline construction drilling rig. Utility Model Content
[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a lifting device for an underground pipeline construction drilling rig.
[0005] To solve the above problems, the present invention adopts the following technical solution:

[0013] (1) In this utility model, by setting up cross support mechanisms at both ends between the base and the top seat, the two ends between the base and the top seat are supported by the cross support mechanisms. When it is necessary to adjust the height of the top seat, two hydraulic rods are used to drive two sliding columns to slide in the sliding groove on the side of the base. The movement of the sliding columns drives the second support arm and the first support arm to move crosswise, thereby adjusting the height of the top seat through the first support arm and the second support arm, and ensuring the stability of the top seat after adjustment, thus improving the practicality of the underground pipeline construction drilling rig lifting device.
[0014] (2) In this utility model, the device can be moved conveniently by the cooperation of the first electric push rod and the moving wheel. In addition, the screw can be rotated by the second servo motor. The rotating screw is driven by the second electric push rod to move down into the ground, which can fix the device on the ground, ensure the stability of the device when in use, and improve the practicality of the underground pipeline construction drilling rig lifting device.

Then, the second servo motor 19 is activated to drive the screw 20 to rotate. The second electric push rod 17 drives the mounting box 18 and the screw 20 downwards, so that the screw 20 spirals into the ground, thereby fixing the base 1 on the ground. Then, when it is necessary to adjust the height of the pipeline drilling rig 26, two hydraulic rods 9 are activated to drive two sliding columns 6 to slide in the sliding groove 4 on the side of the base 1. The movement of the sliding columns 6 drives the second support arm 8 and the first support arm 7 to move crosswise, thereby adjusting the height of the top seat 3 through the first support arm 7 and the second support arm 8. Finally, the pipeline drilling rig 26 drives the drill rod to rotate for construction.
