Description

Technical Field

[0001] This utility model relates to the field of pipeline laying construction technology, and more specifically, to a pipe jacking section hoisting and turning device. Background Technology

[0002] Pipe jacking technology is a non-excavation pipeline laying technology used in municipal construction. Its advantages include minimal or no impact on the surrounding environment, small construction site, low noise, and the ability to work deep underground, which are unmatched by open-cut pipe laying. In municipal construction, pipe jacking sections are important equipment in non-excavation pipeline laying. Before being jacked into the pipeline by the jacking equipment, they must be transported from the storage location to the working shaft by a hoisting device.

[0003] Based on the above, the inventors have discovered that existing pipe jacking sections have directional and angular issues due to sealing requirements. However, the hoisting devices lack effective tilting components, requiring multiple hoisting and tilting operations during transportation and construction. This results in cumbersome, labor-intensive, and difficult pipe jacking construction work. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a pipe jacking section hoisting and tilting device, aiming to achieve a more practical purpose.

This solution is equipped with a turning and adjusting component, which can directly turn and adjust the pipe section during hoisting. It is easy to operate, facilitates the laying and hoisting of the pipe section, reduces the construction difficulty and labor intensity, and is equipped with a pair of limiting components, which can limit and guide the two ends of the pipe section respectively, ensuring the stability of the pipe section rotation and turning, and reducing the occurrence of accidents.

[0006] 2. Technical Solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A pipe jacking section hoisting and tilting device includes a hanger, one end of which is fixedly connected to a drive motor, and a pair of sliding plates are slidably connected to the lower outer side of the hanger. A first cylinder and a second cylinder are respectively fixedly connected to the center of the bottom surface of the two sliding plates.

A support plate is fixedly connected to the output end of the second cylinder, and an adjusting motor is fixedly connected to the outer side of the support plate. A turntable is fixedly connected to the output end of the adjusting motor through the inner side of the support plate.

[0009] The limiting mechanism includes a limiting sleeve, on both sides of which are fixedly connected to telescopic rods, and on the inner side of the limiting sleeve is a set of movable ball bearings.

[0010] Furthermore, the bidirectional lead screw is located centrally inside the hanger and is movably connected to the hanger.

[0011] Furthermore, the ball bearing slider is fixedly connected to the sliding plate through the bottom surface of the hanger.

[0012] Furthermore, the upper limit plate and the lower limit plate are symmetrically arranged, and a set of movable rollers are movably connected to the inner side of both the upper limit plate and the lower limit plate.

[0016] 3. Beneficial effects

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] (1) This scheme uses a two-way screw and two ball bearing sliders to move the sliding plate to adjust the hoisting distance. Then, the upper limit plate and the lower limit plate limit one end of the pipe section. At the same time, the flipping block at the output end of the electric adjustment rod is made to fit with the inner surface of the other end of the pipe section and the movable roller is activated. The adjustment motor is started, and the turntable drives the electric adjustment rod to rotate, thereby making the pipe section flipped and adjusted. Compared with the existing technology, the flipping and adjustment component can be set up to directly flip and adjust the pipe section during hoisting. It is convenient to operate, facilitates the laying and hoisting of the pipe section, and reduces the construction difficulty and labor intensity.

[0019] (2) By setting a limiting mechanism in conjunction with two limiting plates, during the pipe section flipping process, the upper limiting plate and the lower limiting plate limit one end of the pipe section. At the same time, the movable roller reduces the rotational friction of the pipe section. Meanwhile, the limiting sleeve and the telescopic rod limit the turntable. The movable ball reduces the rotational friction of the turntable, thereby limiting the other end of the pipe section. Compared with the prior art, setting a pair of limiting components can limit and guide both ends of the pipe section respectively, ensuring the stability of the pipe section's rotation and flipping, and reducing the occurrence of accidents.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4 A pipe jacking section hoisting and tilting device includes a hanger 1. A drive motor 2 is fixedly connected to one end of the hanger 1, and a pair of sliding plates 3 are slidably connected to the lower outer side of the hanger 1. A first cylinder 4 and a second cylinder 5 are fixedly connected to the bottom surface of the two sliding plates 3 respectively. A bidirectional lead screw 6 is fixedly connected to the output end of the drive motor 2. A pair of ball bearing sliders 7 are sleeved on the outer side of the bidirectional lead screw 6. An upper limit plate 9 is fixedly connected to the output end of the first cylinder 4. A lower limit plate 8 is provided directly below the upper limit plate 9. A support plate 10 is fixedly connected to the output end of the second cylinder 5. An adjusting motor 11 is fixedly connected to the outer side of the support plate 10. A turntable 12 is fixedly connected to the output end of the adjusting motor 11 through the inner side of the support plate 10. A set of electric adjusting rods 13 are fixedly connected to the inner side of the turntable 12, and a limit mechanism 14 is provided on the side of the turntable 12.

[0028] The limiting mechanism 14 includes a limiting sleeve 15, with telescopic rods 16 fixedly connected to both sides of the limiting sleeve 15, and a set of movable balls 17 movably connected to the inner side of the limiting sleeve 15. The limiting mechanism 14 is provided to ensure the stability of the pipe section's rotation.

[0029] See Figure 2 The bidirectional lead screw 6 is located in the center inside the hanger 1 and is movably connected to the hanger 1. First, start the drive motor 2 to drive the bidirectional lead screw 6 to rotate.

[0030] See Figure 2 The ball bearing slider 7 is fixedly connected to the bottom surface of the hanger 1 and the sliding plate 3, so that the two ball bearing sliders 7 move synchronously in opposite directions, thereby driving the sliding plate 3 to move and adjust the hoisting distance.

[0031] See Figure 2 The upper limit plate 9 and the lower limit plate 8 are symmetrically arranged, and a set of movable rollers are movably connected to the inner side of the upper limit plate 9 and the inner side of the lower limit plate 8. One end of the tube is placed on the lower limit plate 8, passes between the two limit plates, and the one end of the tube is made to fit against the inner end face of the support plate 10. Then the first cylinder 4 is started to drive the lower limit plate 8 to move up and down.

[0032] See Figure 3 A limit ring is fixedly connected to the outer side of the turntable 12. The limit ring is fixedly connected to the support plate 10. A flipping block is fixedly connected to the output end of the electric adjusting rod 13. When the second cylinder 5 is started, the support plate 10 drives the turntable 12 to move downward, so that the center of the turntable 12 and the central axis of the pipe section are at the same horizontal position. The flipping block at the output end of the electric adjusting rod 13 is in contact with the inner surface of the pipe section. Then the adjusting motor 11 is started, so that the turntable 12 drives the electric adjusting rod 13 to rotate, thereby causing the pipe section to be flipped and adjusted.

[0033] See Figure 4 The limiting sleeve 15 is located on the outside of the turntable 12 and is movably connected to the turntable 12. The movable ball 17 fits against the outer surface of the turntable 12. The limiting sleeve 15, together with the telescopic rod 16, plays a limiting role on the turntable 12 and reduces the rotational friction of the turntable 12 with the help of the movable ball 17.

[0034] See Figure 4 The top of the telescopic rod 16 and the top surface of the lower limit plate 8 are fixedly connected to the adjacent sliding plate 3, and the connection between the lower limit plate 8 and the sliding plate 3 passes through the upper limit plate 9, so that the upper limit plate 9 and the lower limit plate 8 are respectively attached to the outer side of the pipe section to play a limiting role. At the same time, in conjunction with the movable roller, the rotational friction of the pipe section is reduced.

[0035] In use: First, start the drive motor 2, which drives the bidirectional lead screw 6 to rotate, causing the two ball bearing sliders 7 to move synchronously in opposite directions. This, in turn, moves the sliding plate 3 to adjust the lifting distance. Then, place one end of the pipe fitting on the top surface of the lower limit plate 8. Activate the second cylinder 5 according to the pipe fitting radius. The support plate 10 drives the turntable 12 downwards, aligning the center of the turntable 12 with the central axis of the pipe section at the same horizontal level. Then, make the pipe section fit against the inner end face of the support plate 10. Next, activate the first cylinder 4 to move the lower limit plate 8 up and down. Activating the first cylinder 4 also lowers the upper limit plate 9, causing the upper limit plate 9 and the lower limit plate 8 to fit against the upper and lower sides of the pipe section respectively. Simultaneously, start the electric... The adjusting rod 13 is moved so that the flipping block at its output end fits against the inner surface of the pipe section and engages with the movable roller. The adjusting motor 11 is started, causing the turntable 12 to drive the electric adjusting rod 13 to rotate, thereby causing the pipe section to flip and adjust. During the pipe section flipping process, the upper limit plate 9 and the lower limit plate 8 limit one end of the pipe section. At the same time, the movable roller reduces the rotational friction of the pipe section. Meanwhile, the limiting sleeve 15 and the telescopic rod 16 limit the turntable 12. The movable ball bearing 17 reduces the rotational friction of the turntable 12, thereby limiting the other end of the pipe section and ensuring the stability of the pipe section's rotation and flipping. Finally, the pipe section is hoisted and transported by a crane and the lifting frame 1.
