Description

Technical Field

[0001] This utility model relates to the field of pipeline foundation bedding leveling technology, specifically a leveling device for pipeline foundation bedding. Background Technology

[0002] In recent years, with the development of science and technology, new types of pipe materials and processes have emerged and have replaced traditional pipe materials in the field of municipal engineering. They are mainly used in urban water supply and drainage, gas, communication and power projects, and have played a positive role in promoting urban infrastructure construction.

[0003] However, the construction quality of the pipeline foundation plays a crucial role in the overall installation quality of the pipeline. During the pipeline foundation construction process, due to the limitation of trench width, construction machinery cannot enter the trench for construction, and only manual leveling of the foundation is possible. The traditional manual string line leveling process cannot achieve "point-to-surface" leveling, resulting in poor flatness of the foundation bedding layer. It often requires repeated work to meet the requirements, which is time-consuming and laborious, and greatly affects the construction progress of the pipeline. Therefore, it is necessary to develop a leveling device for pipeline foundation bedding layers to facilitate rapid construction. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned in the background art by providing a leveling device for pipe foundation bedding.

[0005] The technical solution of this utility model to achieve the above objectives is as follows: A leveling device for a pipeline foundation pad includes a positioning mechanism, a track mechanism, and a leveling mechanism. The positioning mechanism is installed above the foundation pad, the track mechanism is installed on the positioning mechanism, and the leveling mechanism is installed on the track mechanism.

[0006] The positioning mechanism is used to fix the track mechanism and control the height of the track mechanism.

[0007] The track mechanism is used to control the movement trajectory of the leveling mechanism.

[0008] The leveling mechanism is used to level the base layer.

[0009] Preferably, the positioning mechanism includes a positioning rod, a horizontal slot, and a movable buckle. The bottom end of the positioning rod is inserted into the foundation pad, the horizontal slot is fixed on the upper side of the positioning rod, and the movable buckle is located above the horizontal slot and connected to the positioning rod by a riveting.

[0010] Preferably, the track mechanism includes a motion track and a connecting buckle. The motion track is inserted between a horizontal slot and a movable buckle, and a connecting buckle is fixed at each end of the motion track.

[0011] Preferably, the leveling mechanism includes a drive shaft, rolling wheels, a leveling plate, and a push rod. A rolling wheel is rotatably mounted at each end of the drive shaft. The rolling wheels are located on a track mechanism. The leveling plate is fixedly mounted below the drive shaft. The push rod is mounted on the drive shaft.

[0012] Preferably, the push rod is rotatably mounted on the drive shaft, the plate is provided with a fixing ring, the fixing ring is fixedly mounted on the plate, the push rod is provided with an adjustment hole, a plurality of the adjustment holes are opened on the push rod, the fixing ring is provided with an adjustment rod, one end of the adjustment rod is inserted into the fixing ring, and the other end of the adjustment rod is inserted into the adjustment hole.

[0013] Preferably, the connecting buckle on one side of the motion track is L-shaped, and the connecting buckle on the other side is U-shaped.

[0014] Preferably, a rubber pad is used to reinforce the space between the motion track, the horizontal slot, and the movable buckle.

[0015] This utility model device, through its structural design and positioning mechanism, ensures that all positioning rods are installed at the same height and strictly conform to the design elevation, laying a precise foundation for subsequent track laying. The track mechanism forms a continuous, straight, and stable guide plane, allowing the leveling mechanism to operate strictly along this predetermined trajectory. The flat plate at the bottom of the leveling mechanism effectively eliminates problems such as flatness errors, wavy surfaces, and elevation deviations that are difficult to avoid in traditional manual operations. The resulting bedding layer has extremely high flatness, providing excellent base conditions for subsequent pipeline laying. Secondly, in terms of construction efficiency, the modular design of the positioning and track system makes installation, disassembly, and relocation extremely convenient, enabling rapid cyclical construction and significantly reducing waiting time between processes. Simultaneously, the leveling mechanism moves smoothly and effortlessly on the track, completing wide-area leveling in a single pass, with higher efficiency than traditional manual leveling. It is particularly suitable for segmented continuous operations in long-distance trenches, thus significantly shortening the overall bedding layer construction period.

[0016] Compared with existing technologies, this utility model is convenient to use and simple to operate, solving the problems of low accuracy and poor flatness of traditional hanging line leveling. It can be operated by 1 to 2 people, which greatly saves labor and effectively improves construction efficiency. This device is mainly suitable for trench leveling with a foundation bedding layer width ≤ 2m, and can achieve precise leveling of various pipeline plain soil bedding layers, lime soil bedding layers and sand bedding layers.

In use, the rolling wheels 32 are placed into the motion tracks 21 on both sides, and the push rod 34 is pushed, causing the leveling plate 33 to move forward along the track mechanism 2, replenishing material to the missing areas. Once all the padding material in one cycle is replenished, the leveling mechanism 3 is pulled backward along the track mechanism 2, and the leveling of the padding surface is completed.

[0027] In this embodiment, the push rod 34 is rotatably mounted on the transmission shaft 31. A fixing ring 4 is provided on the flat plate 33, and the fixing ring 4 is fixedly mounted on the flat plate 33. The push rod 34 is provided with adjustment holes 5, and multiple adjustment holes 5 are opened on the push rod 34. An adjustment rod 6 is provided between the fixing ring 4 and the push rod 34. One end of the adjustment rod 6 is inserted into the fixing ring 4, and the other end of the adjustment rod 6 is inserted into the adjustment hole 5. In use, the angle of the push rod 34 is adjusted by adjusting the position of the adjustment rod 6 in the corresponding adjustment hole 5, which is convenient for people of different heights to operate.

[0028] In this embodiment, the connecting buckle 22 on one side of the motion track 21 is L-shaped, and the connecting buckle 22 on the other side is U-shaped, ensuring that two adjacent motion tracks 21 can be easily connected.

[0029] In this embodiment, a rubber pad is used to reinforce the space between the motion track 21, the horizontal slot 12, and the movable buckle 13.

[0030] In this embodiment, the device of this utility model is first manufactured by workers, and the manufacturing process is as follows: I. Fabrication and installation of positioning mechanism 1; The positioning mechanism 1 is mainly used to fix the track mechanism 2 and control the fixed height of the track mechanism 2. It consists of three parts: a positioning rod 11, a horizontal slot 12, and a movable buckle 13. The positioning rod 11 is made of 16mm diameter round steel, and its end is ground into a sharp point for easy insertion into the foundation pad. The horizontal slot 12 is welded to the upper part of the positioning rod 11. The horizontal slot 12 is "L" shaped and made of 16mm diameter round steel. The movable buckle 13 is set above the horizontal slot 12 and is reliably connected to the positioning rod 11 by riveting.

[0031] II. Fabrication and installation of track mechanism 2; The track mechanism 2 consists of a motion track 21 and connecting buckles 22, used to control the movement trajectory of the leveling mechanism 3. The motion track 21 is made of 3m long lightweight C-shaped steel, with connecting buckles 22 at both ends. The connecting buckles 22 are made of 14mm diameter round steel, machined into "L" and "U" shapes, and are firmly welded to the motion track 21 at designated positions to ensure easy connection between adjacent motion tracks 21.

[0032] III. Fabrication and installation of leveling mechanism 3; The leveling mechanism 3 consists of four parts: a drive shaft 31, rolling wheels 32, a leveling plate 33, and a push rod 34. The drive shaft 31 is made of DN32*3 galvanized steel pipe, its length matching the spacing of the track mechanisms 2 on both sides. The rolling wheels 32 are connected to the drive shaft 31 via bearings. The leveling plate 33, located below the drive shaft 31, is made of 3mm thick steel plate, 200mm wide, and welded to the drive shaft 31. Two fixing rings 4 are welded to both ends of the leveling plate 33. The push rod 34 is made of DN25*2.5 galvanized steel pipe and is connected to the drive shaft 31 via high-strength screws. Three adjustment holes 5 are provided on each side of the push rod 34.

[0033] The adjusting rod 6 is made of 12mm diameter round steel with both ends bent. One end is inserted into the fixing ring 4 and the other end is inserted into the adjusting hole 5. It can not only stabilize the plate 33 and the push rod 34, but also adjust the angle of the push rod 34 by adjusting the position of the adjusting rod 6 in the corresponding adjusting hole 5, which is convenient for people of different heights to operate.

[0034] After the present invention is completed, the leveling of the pipe foundation pad can begin. The overall operation flow is as follows: 1. Insert the positioning mechanism 1 into the trench foundation sequentially along the edge of the pipeline foundation pad, with a spacing of no more than 3m. During the insertion of the positioning mechanism 1, ensure that the positioning rod 11 is vertical and control the height of the horizontal slot 12 with the instrument. The positioning mechanism 1 should be set symmetrically.

[0035] 2. Place the motion track 21 sequentially on the horizontal slot 12 of the positioning mechanism 1. Adjacent motion tracks 21 can be connected by the connecting buckle 22 on the back of the motion track 21. The track mechanism 2 and the positioning mechanism 1 can be fixed by the movable buckle 13 on the rotating positioning rod 11. The gap between the motion track 21 and the horizontal slot 12 and the movable buckle 13 is filled and reinforced with rubber pads.

[0036] 3. Check the spacing and height between the two track mechanisms 2 on both sides, and make timely adjustments if any problems are found.

[0037] Fourth, slowly place the rolling wheel 32 of the leveling mechanism 3 into the motion track 21 on both sides and adjust the angle of the push rod 34.

[0038] 5. Push the leveling mechanism 3 forward along the track mechanism 2, while adding material to the missing material position. The pad material can be slightly higher than the bottom surface of the leveling plate 33.

[0039] VI. Generally, a cycle section of 12 to 15 meters is selected. After all the bedding material in a cycle section is replenished, the leveling mechanism 3 is pulled backward along the track mechanism 2, and the bedding surface can be leveled. The excess bedding material is then promptly cleaned up and moved to the next cycle section.

[0040] 7. After the previous cycle section is leveled, the positioning mechanism 1 and the track mechanism 2 can be removed and moved to the next cycle section for reuse until the leveling work of the entire trench bedding layer is completed.

[0041] Leveling of base pads of different sizes can be achieved by changing the dimensions of the drive shaft and the plate.
