Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0032] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort shall fall within the scope of protection of the present invention.

[0033] Example

[0034] The following reference Figures 1-9 As shown, further described in conjunction with specific embodiments, this embodiment provides a temporary pipe support device for road construction, referring to Figure 1 、 Figure 2As shown, it includes a walking frame 1, a base frame 2, a lifting mechanism 3 and a mounting seat 4. The walking frame 1 is arranged at the upper part of the trench. The four corners of the bottom of the walking frame 1 are provided with walking wheels 11 to facilitate pushing the walking frame 1 to move above the trench along the length direction of the trench. Both sides of the top of the walking frame 1 are provided with lifting components 12. The lifting components 12 include a winch 121 and a lifting belt 122 hung at the bottom of the winch 121; the base frame 2 is vertically arranged at the bottom of the walking frame 1 and extends into the trench. The first fitting seat 21 and the second fitting seat 22 are respectively provided at both ends of the bottom of the base frame 2; the pulling mechanism 3 is arranged at one end of the base frame 2 and is used to lift the end of the pipe in the trench upward. Push the walking frame 1 along the length direction of the trench to above the end of the installed pipe in the trench, lift the end of the pipe in the trench upward through the lifting mechanism 3, and then install the lifting belts 122 at the bottom of the two sets of lifting components 12 to the specified position of the pipe in the trench, and lift the pipe in the trench through the winch 121 until the pipe is in a fitting state with the first fitting seat 21 and the second fitting seat 22, that is, the direction of the end of the pipe in the trench can be guaranteed, and the two pipes can be conveniently docked by making the direction of the pipe outside the trench consistent with that of the pipe in the trench.

[0035] Reference Figure 1 、 Figure 2 As shown, the mounting seat 4 is welded to one end of the base frame 2. The mounting seat 4 is provided with a guide mechanism 5 for the passage of the pipe and a clamping mechanism 6 for fixing the position of the pipe. The guide mechanism 5 includes a guide seat 51 and a guide ring 52 provided at the bottom of the guide seat 51. The clamping mechanism 6 includes a clamping seat 61 and a clamping ring 62 provided at the bottom of the clamping seat 61. The first fitting seat 21, the second fitting seat 22, the guide ring 52 and the clamping ring 62 are all tilted and aligned in the same axial direction. One end of the pipe in the trench is lifted upward and fitted with the first fitting seat 21 and the second fitting seat 22. Then, the pipe outside the trench is inserted into the guide ring 52 and clamped by the clamping ring 62. This allows the pipe inside the trench to be coaxial with the pipe outside the trench, thereby facilitating docking operations. For pipes of different materials and types, the docking operation may be carried out by welding, hot melt connection and socket connection. Since the present application limits the position direction of the pipe outside the trench by the guide mechanism 5 and fixes the adjusted position of the pipe by the clamping mechanism 6, after the adjustment is completed, the pipe outside the trench and the pipe inside the trench always have the same axial direction, so it can adapt to the operation process of the above-mentioned multiple connection methods.

[0036] Reference Figure 2 、 Figure 3As shown, the winch 121 is fixedly installed on the top of the traveling frame 1, and a hook 1211 is provided on the steel rope of the winch 121, and a hanging ring 1221 for hanging the hook 1211 is provided on the lifting belt 122. The two ends of the lifting belt 122 are detachably connected by connecting bolts 1222 and connecting nuts 1223. First, one end of the pipeline is lifted upward by the lifting mechanism 3 to facilitate the installation of the lifting belt 122 on the pipeline. Then, the connecting bolts 1222 are sequentially passed through the through holes pre-opened at both ends of the lifting belt 122. Then, by screwing the connecting nuts 1223 into the connecting bolts 1222, the state of the lifting belt 122 can be maintained, so that the lifting belt 122 forms a closed loop to facilitate the lifting operation of the pipeline.

[0037] Reference Figure 4 、 Figure 5 As shown, the lifting mechanism 3 includes a support seat 31, which is welded to the base frame 2. A lifting cylinder 32 is installed at the bottom of the support seat 31, and a lifting assembly 33 is provided on the piston rod of the lifting cylinder 32; the lifting assembly 33 includes a lifting seat 331 and a lifting block 332, and a rotating groove 3311 is opened on one side of the lifting seat 331, and the lifting block 332 is rotatably connected in the rotating groove 3311 through a first rotating shaft 333 and one end of the lifting block 332 extends to the outside of the rotating groove 3311, and when the lifting block 332 rotates to a horizontal state, it abuts against the bottom wall of the rotating groove 3311, and a torsion spring 334 is connected between the first rotating shaft 333 and the lifting seat 331 for driving the lifting block 332 to rotate toward a horizontal state. Start the lifting cylinder 32 and move the piston rod of the lifting cylinder 32 out of the cylinder, which can drive the lifting assembly 33 to move into the trench. When the lifting block 332 moves to contact the pipe, it can rotate upward from a horizontal state to a vertical state to pass through the pipe wall of the pipe. When the lifting assembly 33 is driven upward as a whole by the lifting cylinder 32, the lifting block 332 will not rotate under the abutment of the bottom wall of the rotating groove 3311, so that the pipe can be pulled upward, so that the bottom of the pipe is separated from the bottom wall of the trench, so as to facilitate the installation of the lifting belt 122 on the pipe.

[0038] Reference Figure 5 As shown, the lifting seat 331 is rotatably mounted on the piston rod of the lifting cylinder 32. A positioning collar 335 is provided on the top of the lifting seat 331. A positioning collar 335 is provided on the positioning collar 335 for fixing the position of the lifting seat 331. After the lifting belt 122 is installed on the pipeline, the pipeline is further lifted upward by the two winches 121, so that the lifting assembly 33 can be separated from the pipe wall. The positioning pin 3351 is removed and the lifting seat 331 is rotated 90 degrees, so that the lifting block 332 can be moved to the outside of the pipeline. Then, the lifting cylinder 32 drives the lifting assembly 33 to move upward as a whole, so that the lifting assembly 33 can be located above the pipeline, thereby not affecting the subsequent pipeline docking operation.

[0039] Reference Figure 1 、 Figure 2 As shown, the traveling frame 1 is provided with a through slot for the base frame 2 to pass through, and the traveling frame 1 is also provided with a lifting mechanism 14 for driving the base frame 2 to move along the height direction of the traveling frame 1. After the pipeline construction is completed, the base frame 2 is driven upward by the lifting mechanism 14, that is, the first fitting seat 21, the second fitting seat 22, the guide mechanism 5 and the clamping mechanism 6 can all be moved upward to the outside of the pipeline trench. As shown in Figure 6, an extension frame 13 is welded to one side of the bottom of the traveling frame 1, and a vertical seat 42 is provided at the bottom of the mounting seat 4. The extension frame 13 is provided with a through slot for the vertical seat 42 to pass through, so as to improve the stability of the mounting seat 4.

[0040] Reference Figure 1 As shown, the lifting mechanism 14 includes a lifting motor 141, a driving screw 142 and a driving beam 23. The driving screw 142 is connected to the traveling frame 1 in a rotational direction along the height direction of the traveling frame 1. The lifting motor 141 is fixedly arranged at the top of the traveling frame 1 and the output shaft of the lifting motor 141 is fixedly connected to the driving screw 142. One end of the driving beam 23 is threadedly connected to the driving screw 142 and the other end is fixedly connected to the base frame 2. The base frame 2 is also provided with a guide beam 24. A guide rod 143 is provided on the traveling frame 1 and is located on the side opposite to the driving screw 142. The guide beam 24 is provided with a guide hole and is sleeved on the guide rod 143. When the lifting motor 141 is started to drive the driving screw 142 to rotate, the base frame 2 can be driven as a whole by the driving beam 23. Under the guidance of the guide rod 143 and the guide beam 24, the base frame 2 can be moved vertically into or out of the pipe trench.

[0041] Reference Figure 6 、 Figure 8As shown, the guide seat 51 is fixedly arranged at the bottom of the mounting seat 4, and the guide seat 51 includes a vertical seat 511, and an inclined seat 512 is inclined at the bottom of the vertical seat 511. A hollow groove 5121 is opened in the middle of the inclined seat 512, and the hollow groove 5121 separates the two sides of the inclined seat 512 into two fork arms 5122. The bottom of the two fork arms 5122 are hingedly provided with a rotating arm 513, and a straightening assembly 53 is arranged in the hollow groove 5121. The straightening assembly 53 is used to drive the two rotating arms 513 to remain in a parallel state with the fork arms 5122; the guide ring 52 includes two guide half rings 521, and the two guide half rings 521 are respectively arranged at the bottom of the two rotating arms 513. When it is necessary to place the pipe outside the trench into the guide mechanism 5 and guide it, the two rotating arms 513 are kept parallel to the fork arm 5122 through the straightening assembly 53. At this time, the two guide half rings 521 are in a closed state and form a guide ring 52. The inner wall of the guide ring 52 can fit with the outer wall of the pipe and guide the pipe. After the pipe outside the trench is docked with the pipe inside the trench, the straightening assembly 53 is detached from the connection between the rotating arm 513 and the fork arm 5122. The two rotating arms 513 are not restricted by the straightening assembly 53 and can drive the guide half rings 521 to rotate in a direction away from each other and detach from the pipe, thereby conveniently realizing the separation process of the guide mechanism 5 and the pipe.

[0042] Reference Figure 8 As shown, the straightening assembly 53 includes a straightening electric cylinder 531, and a driving plate 532 is connected to the piston rod of the straightening electric cylinder 531. Straightening sleeves 533 are provided on both sides of the driving plate 532. When the straightening sleeves 533 are mounted on the connecting portion of the fork arm 5122 and the rotating arm 513, they can prevent the rotating arm 513 and the fork arm 5122 from rotating relative to each other, so that the two guide half rings 521 are in a state of being close to each other; when the straightening electric cylinder 531 drives the driving plate 532 to move upward, the driving plate 532 drives the straightening sleeve 533 to move synchronously and move to the side of the fork arm 5122 away from the rotating arm 513, so that the position of the rotating arm 513 is no longer restricted. After the pipeline is docked, when it is lowered by the lifting assembly 12, the two guide half rings 521 can rotate freely so that the pipeline can be moved out of the guide mechanism 5.

[0043] Reference Figure 6 、 Figure 7As shown, the clamping seat 61 includes an arcuate seat 611 and a driving seat 612 arranged at the bottom of the arcuate seat 611. The arcuate seat 611 is rotatably arranged on the side of the mounting seat 4 away from the base frame 2 via a second rotating shaft 613. The mounting seat 4 is provided with a rotating assembly 41 for driving the arcuate seat 611 to rotate. The driving seat 612 is fixedly arranged at one end of the arcuate seat 611 away from the mounting seat 4. The clamping ring 62 includes two clamping half rings 621. The driving seat 612 is provided with a driving assembly 63 for driving the two clamping half rings 621 to move simultaneously toward or away from each other. When it is necessary to dock a pipe located outside the trench with a pipe inside the trench, the arcuate seat 611 is driven to rotate into the trench by the rotating assembly 41, and then one end of the pipe is inserted into the guide mechanism 5. After adjusting the position, the driving assembly 63 drives the two clamping half rings 621 to clamp the pipe to achieve positioning, so as to facilitate the subsequent docking operation of the two pipes.

[0044] Reference Figure 7 、 Figure 8 As shown, a support arm 54 for supporting the arc-shaped seat 611 is tiltedly provided on one side of the vertical seat 511, and a support block 541 is provided on the support arm 54. The support block 541 is provided with a support groove 5411 adapted to the shape of the arc-shaped seat 611, and a contact switch 542 for starting the straightening electric cylinder 531 is provided in the support groove 5411. When the arc-shaped seat 611 is rotated to fit into the support groove 5411, the contact switch 542 can turn on the straightening electric cylinder 531 to drive the straightening sleeve 533 to move to the connection position between the fork arm 5122 and the rotating arm 513. When the arc seat 611 is driven to rotate to a specified position in the trench by the rotating component 41, the arc seat 611 is in contact with the support groove 5411 and the contact switch 542 is activated to turn on the straightening cylinder 531. The piston rod of the straightening cylinder 531 drives the straightening sleeve 533 to move through the driving plate 532 and fixes the relative positions of the rotating arm 513 and the fork arm 5122, so that the two guide half rings 521 are close to each other to form a guide ring 52, so as to guide the pipeline.

[0045] Reference Figure 7 As shown, the drive assembly 63 includes a drive motor 631, a double-axis lead screw 632 and two drive blocks 633. A drive groove 6121 is provided on the side of the drive seat 612 facing away from the arc seat 611. The double-axis lead screw 632 is rotatably connected in the drive groove 6121.

The two drive blocks 633 are both slidably arranged in the drive groove 6121 and are respectively threadedly connected to the two ends of the double-axis lead screw 632. Starting the drive motor 631 drives the bidirectional lead screw to rotate, that is, the two clamping half rings 621 can be driven to move in a direction close to each other through the two drive blocks 633, and the pipeline is clamped to achieve the positioning effect. Figure 9As shown, the rotating assembly 41 includes a rotating motor 411, a worm gear 412, a worm 413, and two mounting blocks 414. The worm gear 412 is coaxially connected to the second rotating shaft 613. The two mounting blocks 414 are welded to the mounting seat 4. The worm 413 is rotatably connected between the two mounting blocks 414 and meshes with the worm gear 412. The rotating motor 411 is fixedly mounted on one of the mounting blocks 414, and the output shaft of the rotating motor 411 is coaxially connected to the worm 413. The rotating motor 411 drives the worm 413 to rotate, which can drive the arc seat 611 to rotate through the worm gear 412, and can maintain the stability of the position after rotation.
