[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] Please see Figure 1-4 The present invention provides the following technical solution: an angle adjustment device for pipe jacking machine construction, including a base 1 and a pipe jacking machine body 2 provided on the top surface of the base 1. Two symmetrical support blocks 3 are installed at one end of the top surface of the base 1. Rotating shafts 4 are installed on the corresponding side walls of the two support blocks 3. Rotating grooves 5 are opened inside the support blocks 3. Two symmetrical fixing blocks 6 are provided at the other end of the base 1 relative to the top of the support blocks 3. Threaded rods 7 are threadedly connected to the surface of the fixing blocks 6. Support feet 8 are installed at the top of the threaded rods 7.

[0022] In a preferred embodiment: the rotating shaft 4 is adapted to the rotating groove 5, and the rotating shaft 4 and the rotating groove 5 are in a "T" shape.

[0023] In a preferred embodiment: the end of the rotating shaft 4 is connected to the outer side wall of one end of the pipe jacking machine body 2, and the pipe jacking machine body 2 is rotatably connected to the support block 3 through the rotating shaft 4.

[0024] In a preferred embodiment: the outer side wall of the other end of the pipe jacking machine body 2 is connected to the corresponding side walls of the two fixing blocks 6, and the pipe jacking machine body 2 forms a lifting connection with the base 1 through the fixing blocks 6 and the threaded rod 7.

[0025] In the embodiment, firstly, the pipe jacking machine body 2 is composed of the pipe jacking machine body, hydraulic components and rails. The pipe jacking machine body 2 belongs to existing mature technology, so it will not be described in detail in the text.

[0026] During construction, the pipe jacking machine body 2 needs to adjust its construction angle according to the inclined line. First, the base 1, together with the pipe jacking machine body 2, is fixed in the initial construction position. Next, the threaded rod 7 is rotated, causing it to descend along the surface of the fixing block 6 until the support foot 8 approaches the top of the base 1. As the threaded rod 7 continues to rotate, the fixing block 6 is lifted, thereby changing the height of the pipe jacking machine body 2. Subsequently, the other end of the pipe jacking machine body 2 rotates within the rotating groove 5 via the rotating shaft 4, causing the pipe jacking machine body 2 to form the required inclination angle, thus adjusting its construction angle according to the inclined line to meet various construction requirements. Simultaneously, it is ensured that the pipe jacking machine body 2 remains securely connected to the track to prevent detachment.

[0027] It is worth noting that, since the pipe jacking machine body 2 is tilted after adjustment, in order to ensure effective support between the threaded rod 7 and the base 1, the fixing block 6 and the pipe jacking machine body 2 need to be designed as a rotating connection.

[0028] Example 2

[0029] Please see Figure 1-4 The top of the base 1 near the support block 3 is connected to a support plate 9. Two symmetrical limit pins 10 are connected through the surface of the support plate 9. The surface of the base 1 is provided with a through hole 11 for the limit pins 10 to move out. The surface of the limit pins 10 is threaded with a fixing piece 12.

[0030] In a preferred embodiment, the limiting pin 10 is detachably fixedly connected to the support plate 9 via the fixing piece 12.

[0031] In a preferred embodiment, the diameter of the limiting pin 10 is smaller than the opening size through the through hole 11 and the surface of the support plate 9.

[0032] In this embodiment, as described in Embodiment 1, after fixing the base 1 together with the pipe jacking machine body 2 in the initial construction position, the following measures are taken to ensure stability: First, the limiting pin 10 is passed through the base 1 and fixedly connected to the ground. This step effectively anchors one end of the base 1, preventing it from moving, thereby avoiding unnecessary changes in the position of the pipe jacking machine body 2 and ensuring the smooth progress of the construction process. Furthermore, the fixing plate 12 is connected to the limiting pin 10 via a threaded connection. This design allows for flexible adjustment of the position of the fixing plate 12. This not only ensures that the limiting pin 10 remains firmly on the support plate 9, avoiding the risk of detachment, but also ensures that the limiting pin 10 can function properly, thanks to the adjustability of the fixing plate 12.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
