Drainage outlets are opened on both sides of the bottom wall of the lifting frame.

[0017] The present invention has the following beneficial effects:

[0018] (1) The oil pipeline support, when the operating handle is rotated, drives the operating rod and the two-way screw to rotate, the screw blocks move away from or towards each other along the outer wall of the two-way screw, the moving seat and the sliding block follow the movement, and the sliding block slides along the limit rod. When the two moving seats move away from each other, they will drive the X-shaped frame and the lifting plate to descend, and when the moving seats move towards each other, they will drive the X-shaped frame and the lifting plate to rise. After the oil pipeline height adjustment in the inner wall of the fixed arc seat is completed, the heights of the two oil pipelines are made to be roughly the same. The sliding operating handle moves on the outer wall of the operating rod, and then drives the positioning rod to slide in the inner wall of the through-hole so that the rubber column enters the corresponding limit hole, completes the limit fixation of the two-way screw, and prevents it from rotating. At the position of the pipeline connection, by operating the adjustment component according to the height of the two pipelines, the height of the pipeline can be adjusted to a roughly horizontal state, avoiding the situation that the pipeline connection is misaligned due to terrain installation, thereby improving the adaptability of the entire device. At the same time, the overall adjustment method is relatively simple, the cost is low, and it can be used in large quantities.

[0019] (2) The oil pipeline support, the handle drives the support frame to rise, and the support frame drives the support rod body, the lifting frame, the adjustment component, and the fixing component to rise when the support frame rises. When the support frame rises, it drives the limit slider to slide along the inner wall of the corresponding limit slide groove. When the lifting frame rises to a height matching the oil pipeline, the movable accommodation block drives the support block and the stud to move, and the accommodation block is placed in the inner wall of the accommodation groove. The support block enters the inner wall of the square opening through the through hole to support the support frame. The stud enters the inner wall of the corresponding circular hole and passes through the corresponding center hole. It is then screwed to the rear part of the outer wall of the stud through the screw seat. When the entire device is used, the height of the lifting frame and the fixed arc seat can be adjusted according to the height of the oil pipeline. Then, the oil pipeline passes through different terrains to prevent the entire device from being incompatible due to the fixed height. This improves the environmental adaptability of the entire device and can provide auxiliary services for the laying of the oil pipeline.

[0020] (3) The oil pipeline support is installed at the position of the oil pipeline connection. The two oil pipelines to be connected are placed on the positions of the fixed arc seat and the corresponding anti-skid support pad inner wall. Then, the lifting plate, the support seat and the abutment seat are driven to rise by adjusting the adjustment component, and then the fixed arc seat, the anti-skid support pad and the corresponding oil pipeline are driven to rise or fall, so that the two ends of the oil pipeline are kept horizontal. Then, the anti-skid support pad is driven by the movable arc seat to be placed on the corresponding fixed arc seat inner wall, and the movable arc seat is screwed and fixed to the fixed arc seat by a bolt and nut group. Since the entire device is installed with the connection position of the oil pipeline, after the height adjustment between the two pipelines is completed, the oil pipeline can be limited and fixed by the mutual cooperation of the fixed arc seat and the movable arc seat.

[0021] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Specifically, a plurality of square openings 47 are evenly formed on the front wall of the support column 46, and a center hole 48 is formed on the front wall of the support column 46 at positions corresponding to the left and right sides of the square opening 47. A receiving groove 43 is formed on the bottom of the front wall of the support frame 41, and a through opening 45 is formed on the inner wall of the receiving groove 43 at a position corresponding to the square opening 47, and a circular hole 44 is formed on the left and right sides of the inner wall of the receiving groove 43.

[0052] In this embodiment, after the stud 412 passes through the circular hole 44 and the corresponding center hole 48, the stud 412 is screwed and fixed by a screw seat, so that the positions of the support column 46 and the support frame 41 are fixed after sliding adjustment.

[0053] Specifically, embedded parts 2 are installed on the bottom wall of the base 1, support rods 6 are fixedly installed on the top of the outer wall of the support frame 41, the tops of several support rods 6 are fixedly connected to the bottom wall of the lifting frame 5, and drainage ports 9 are opened on both sides of the bottom wall of the lifting frame 5.

[0054] In this embodiment, the embedded parts 2 are embedded and solidified by concrete, and the support rod 6 is provided to improve the installation stability of the lifting frame 5. The drainage port 9 is used to drain rainwater inside the lifting frame 5 when it rains.

[0055] During operation, first, when using the entire device, the embedded part 2 is embedded in the concrete, and the base 1 is fixed to the top wall of the embedded part 2. The lifting assembly 4 is adjusted according to the height of the oil pipeline, and the support frame 41 is driven to rise by the handle 42. When the support frame 41 rises, it drives the support rod body 6, the lifting frame 5, the adjustment assembly 8, and the fixing assembly 7 to rise. When the support frame 41 rises, it drives the limit slider 413 to slide along the inner wall of the corresponding limit slide groove 49. When the lifting frame 5 rises to the height matching the oil pipeline, the support block 411 and the stud 412 are driven to move through the movable accommodating block 410, and the accommodating block 410 is placed in the inner wall of the accommodating groove 43.

Since the entire device is installed at the position of the oil pipeline connection, the two oil pipelines to be connected are placed on the positions of the fixed arc seat 73 and the corresponding anti-skid support pad 72 inner wall, and then the lifting plate 76, the support seat 75 and the abutment seat 74 are driven to rise by adjusting the adjustment component 8, thereby driving the fixed arc seat 73, the anti-skid support pad 7 2 and the corresponding oil pipeline rises or falls, so that the positions of the two ends of the oil pipeline are kept horizontal. Specifically, the operating handle 87 is rotated to drive the operating rod 89 to rotate. When the operating rod 89 rotates, it drives the bidirectional screw rod 81 to rotate.

If the moving seats 85 are close to each other, It will drive the X-shaped frame 86 and the lifting plate 76 to rise. After the height adjustment of the oil pipeline in the inner wall of the fixed arc seat 73 is completed, the heights of the two oil pipelines are made to be roughly the same. The sliding operating handle 87 moves on the outer wall of the operating rod 89, thereby driving the positioning rod 811 to slide in the inner wall of the through-hole 810 so that the rubber column 88 enters the corresponding limiting hole 812, completing the limiting fixation of the two-way screw rod 81 to prevent it from rotating. Then, the anti-skid support pad 72 is driven by the movable movable arc seat 71 to be placed on the corresponding inner wall of the fixed arc seat 73, and the movable arc seat 71 is screwed and fixed to the fixed arc seat 73 by the bolt and nut group 77, thereby completing the support of the oil pipeline.
