Description

Technical Field

[0001] This application relates to the field of auxiliary devices for pipeline construction, and in particular to a stable support device for auxiliary positioning in municipal pipeline construction. Background Technology

[0002] During municipal pipeline construction, multiple pipelines need to be connected and installed. During this process, the position of the pipeline to be installed usually needs to be constantly adjusted to align with the existing pipelines. This pipeline adjustment and positioning process is time-consuming and labor-intensive, resulting in low pipeline installation efficiency. Summary of the Invention

[0003] To address the cumbersome process of pipeline adjustment and positioning, this application provides a stable support device for auxiliary positioning in municipal pipeline construction.

[0004] The present application provides a stable support device for assisted positioning in municipal pipeline construction, which adopts the following technical solution:

[0005] A stabilizing support device for auxiliary positioning in municipal pipeline construction, comprising:

[0006] Base;

[0007] A fixing plate is fixedly mounted on the base, and the fixing plate has a first through hole;

[0008] A sliding plate is slidably mounted on the fixed plate;

[0009] A driving mechanism, disposed on the sliding plate, is used to drive the sliding plate to slide horizontally;

[0010] Two support frames are raised and lowered on the sliding plate to support the support track; a first pull rope is fixed to both sides of the top of the support frame, and a second pull rope is fixed to both sides of the middle of the support frame.

[0011] Two sets of first winding mechanisms are disposed on the sliding plate. Each set of first winding mechanisms is used to synchronously wind or unwind two first pull ropes on the same support frame.

[0012] Four sets of second winding mechanisms are installed on the base, and each set of second winding mechanisms is used to wind up or unwind each second pull rope.

[0013] An auxiliary alignment mechanism is installed inside both the installed pipe and the pipe to be installed, and is used to align the axis of the pipe to be installed with the axis of the installed pipe.

[0014] The pipe to be installed is placed on two support brackets. A first winding mechanism winds up or unwinds the first pull rope, raising or lowering the support brackets to adjust the pipe's vertical position. A second winding mechanism winds up or unwinds the second pull rope, adjusting the pipe's horizontal position. An auxiliary alignment mechanism aligns the axis of the pipe to be installed with the axis of the installed pipe. Then, a drive mechanism moves a sliding plate horizontally, bringing the pipe to be installed closer to the installed pipe along its own axis. During this process, the second winding mechanism winds up or unwinds each second pull rope, adaptively adjusting their length as the pipe moves. This allows for pipe positioning and connection, improving installation efficiency.

[0015] Furthermore, the first winding mechanism includes a first motor, which is a dual-head motor, with its two output ends respectively connected to winding rollers for the corresponding first pull rope to be wound, and the sliding plate has a second through hole for the first pull rope to pass through.

[0016] The first motor drives the corresponding winding roller to wind or unwind the first pull rope, thereby adjusting the position of the support frame in the vertical direction. Since the first motor is a double-headed motor, the two first pull ropes on each support frame are wound or unwound synchronously, which helps to prevent the support frame from tipping over, thereby reducing the possibility of pipe rotation and improving the accuracy of pipe positioning.

[0017] Furthermore, the second winding mechanism includes a second motor, the output end of which is connected to a winding roller for winding the second pull rope.

[0018] The second motor drives the corresponding winding roller, which can wind or unwind the second pull rope, thereby adjusting the position of the support frame in the horizontal direction.

[0019] Furthermore, the auxiliary alignment mechanism includes a disc and four internally threaded sleeves fixed to the periphery of the disc, with the length directions of two adjacent internally threaded sleeves perpendicular to each other; each internally threaded sleeve is threadedly connected to a first threaded rod, and an abutment plate is provided at the end of the first threaded rod away from the internally threaded sleeve, the abutment plate being an arc-shaped plate adapted to the contour of the inner wall of the pipe; when the four abutment plates abut against the inner wall of the pipe respectively, the disc is coaxial with the pipe, and a sensing component for determining whether two discs are coaxial is provided on the disc.

[0020] Auxiliary alignment mechanisms are installed inside the two pipes that need to be aligned. During installation, the four first threaded rods are rotated to make the four arc-shaped abutment plates abut against the inner wall of the pipe. At this time, the discs and pipes are coaxial. During the adjustment of the pipe position, the sensing components determine whether the two discs are coaxial. When the two discs are coaxial, the two pipes are coaxial, thus completing the pipe positioning.

[0021] Furthermore, a level is mounted on the disc, the length direction of which is parallel to the length direction of two of the internal threaded sleeves; the sensing component includes an infrared device mounted on the disc, and when the two pipes are connected, the infrared device in one pipe is an infrared transmitter and the infrared device in the other pipe is an infrared receiver, the positions of the infrared transmitter and the infrared receiver on the disc correspond to each other.

[0022] During the installation of the auxiliary alignment mechanism, adjust the installation angle of the auxiliary alignment mechanism. When the bubble in the level is in the middle of the level, it means that the two internal threaded sleeves in the auxiliary alignment mechanism are horizontal. This ensures that the installation angle of the auxiliary alignment mechanism in the two pipes is the same. During the alignment of the two pipes, one pipe is stationary and the other pipe moves horizontally. When the infrared light emitted by the infrared emitter in one pipe is received by the infrared receiver in the other pipe, it means that the discs in the two pipes are coaxial, that is, the two pipes are coaxial.

[0023] Furthermore, a sensor light is installed on the disc, and the sensor light is connected to the infrared receiver.

[0024] When the axes of the two pipes are aligned, the infrared light emitted by the infrared transmitter in one pipe is received by the infrared receiver in the other pipe, and the sensor light illuminates, indicating to the operator that the two pipes are aligned.

[0025] Furthermore, the longitudinal section of the support frame is V-shaped, and an anti-slip structure is provided on the surface of the support frame that contacts the pipe.

[0026] The V-shaped support bracket supports the pipeline, and the anti-slip structure increases the friction between the support bracket and the pipeline, thereby reducing the rotation and offset of the pipeline on the support bracket, improving the stability of pipeline placement, and helping to improve the accuracy of pipeline positioning.

[0027] Furthermore, the open end of the support frame is provided with an elastic band, which is tensioned on the upper end face of the pipe to limit the pipe.

[0028] When the pipe is placed on the support, the tensioned elastic band above the pipe limits its movement, reduces pipe rotation and offset, improves the stability of pipe placement, and thus improves the accuracy of pipe positioning.

[0029] Furthermore, two parallel slide rails are fixedly mounted on the fixed plate, and the driving mechanism includes a plurality of rollers rotatably mounted on the slide plate. The rollers are adapted to slide along the slide rails, and the slide plate is provided with a driving component for driving the rollers to rotate.

[0030] The rollers are driven to rotate by the drive component, thereby causing the slide plate to slide along the slide rail, thus realizing the horizontal movement of the slide plate.

[0031] Furthermore, a support mechanism is provided at the bottom of the base for fixing the base to the ground.

[0032] During the pipe connection process, the base is fixed to the ground by the support mechanism, thereby improving the stability of the device, reducing device offset, and thus improving the accuracy of pipe positioning.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. By setting up a support frame, a first pull rope, and a first winding mechanism, the position of the pipeline in the vertical direction can be adjusted. By setting up a second pull rope and a second winding mechanism, the position of the pipeline in the horizontal direction can be adjusted, thereby achieving pipeline positioning. By setting up a sliding plate and a driving mechanism, the pipeline can be translated along its own axis, thereby achieving pipeline docking and improving pipeline installation efficiency.

[0035] 2. By setting up an auxiliary alignment mechanism, the pipeline can be positioned in an auxiliary manner during pipeline installation, thereby improving the efficiency of pipeline docking;

[0036] 3. By installing anti-slip structures and elastic bands on the support frame, it helps to prevent pipe rotation and slippage, improves the stability of pipe placement, and thus improves the accuracy of pipe positioning. Attached Figure Description

Detailed Implementation

[0043] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0044] This application discloses a stable support device for assisted positioning in municipal pipeline construction. (Refer to...) Figure 1 and Figure 2 The stabilizing support device for auxiliary positioning in municipal pipeline construction includes a base 1 and four vertical support columns 3 fixedly mounted on the base 1. A horizontal fixing plate 4 is fixedly connected to each of the four support columns 3, and a first through hole 5 is provided on the fixing plate 4. A sliding plate 7 is slidably mounted on the fixing plate 4, and a driving mechanism 6 is provided on the sliding plate 7 to drive the sliding plate 7 to slide horizontally.

[0045] Reference Figure 1 and Figure 3 Two support frames 10 are mounted on the sliding plate 7 to support the guide rail 11. The longitudinal section of each support frame 10 is V-shaped. First pull ropes 9 are fixed to both sides of the top of each support frame 10, and second pull ropes 142 are fixed to both sides of the middle of each support frame 10. Both the first pull ropes 9 and the second pull ropes 142 are steel wire ropes. Two sets of first winding mechanisms are provided on the sliding plate 7. Each set of first winding mechanisms is used to simultaneously wind or unwind the two first pull ropes 9 on the same support frame 10. Four sets of second winding mechanisms 14 are provided on the base 1. Each set of second winding mechanisms 14 is used to wind or unwind each second pull rope 142.

[0046] Reference Figure 3 Both the installed pipe 11 and the pipe to be installed 11 are equipped with an auxiliary alignment mechanism 13, which is used to align the axis of the pipe to be installed 11 with the axis of the installed pipe 11.

[0047] The pipe 11 to be installed is placed on two support brackets 10. The first winding mechanism winds or unwinds the first pull rope 9, raising or lowering the support brackets 10 and adjusting the vertical position of the pipe 11. The second winding mechanism 14 winds or unwinds the second pull rope 142, adjusting the horizontal position of the pipe 11. The auxiliary alignment mechanism 13 aligns the axis of the pipe 11 to be installed with the axis of the installed pipe 11. Then, the drive mechanism 6 moves the sliding plate 7 horizontally, bringing the pipe 11 closer to the installed pipe 11 along its own axis. During this process, the second winding mechanism 14 winds or unwinds each of the second pull ropes 142, adaptively adjusting the length of each second pull rope 142 as the pipe 11 moves. This allows for the positioning and connection of the pipe 11, improving the efficiency of pipe installation.

[0048] Reference Figure 3 An anti-slip structure is provided on the surface of the support 10 that contacts the pipe 11. In this embodiment, the anti-slip structure is a dotted protrusion made of rubber. The anti-slip structure increases the friction between the support 10 and the pipe 11, thereby reducing the rotation and offset of the pipe 11 on the support 10, improving the stability of the pipe 11 placement, and helping to improve the accuracy of pipe 11 positioning. On the other hand, the dotted protrusion made of rubber helps to reduce the wear of the support 10 on the surface of the pipe 11.

[0049] Reference Figure 3 and Figure 4 The support bracket 10 has an elastic band 124 at its open end. The elastic band 124 is tensioned on the upper end face of the pipe 11 to limit the movement of the pipe 11. The support bracket 10 is provided with a fixing component 12 for fixing the elastic band 124.

[0050] Specifically, refer to Figure 3 and Figure 4 The fixing component 12 includes connecting seats 128 fixed to both sides of the support frame 10, and fixing seats 125 and fixing blocks 121 fixed to the connecting seats 128. The connecting seats 128 are fixedly connected to the first pull rope 9 on the same side. A second threaded rod 126 is threaded through the fixing seat 125. A groove 122 is provided on the fixing block 121. A slider 123 fixedly connected to the elastic band 124 is slidably disposed in the groove 122. The slider 123 is provided with an insertion hole 127 for the end of the second threaded rod 126 to be inserted.

[0051] The pipe 11 is placed on the support 10. Then, the sliders 123 at both ends of the elastic band 124 are respectively engaged in the grooves 122 of the fixing block 121 on the same side. The second threaded rod 126 is rotated so that its end is inserted into the insertion hole 127 to fix both ends of the elastic band 124 and to tension the elastic band 124. The tensioned elastic band 124 limits the pipe 11, reduces the rotation and offset of the pipe 11 on the support 10, improves the stability of the pipe 11 placement, and thus improves the accuracy of the pipe 11 positioning.

[0052] Reference Figure 1 and Figure 2 The first winding mechanism includes a first motor 8, which is a double-headed motor. Its two output ends are respectively connected to winding rollers for winding two first pull ropes 9. The sliding plate 7 has a second through hole 71 for the first pull ropes 9 to pass through.

[0053] The first motor 8 drives the corresponding winding roller to rotate, which can wind or unwind the first pull rope 9, thereby adjusting the vertical position of the support frame 10. Since the first motor 8 is a dual-head motor, the two first pull ropes 9 on each support frame 10 wind or unwind synchronously, helping to prevent the support frame 10 from tipping over, thus reducing the possibility of the pipe 11 rotating and improving the positioning accuracy of the pipe 11. The consistent winding or unwinding speed of the two first motors 8 drives the two support frames 10 to rise and fall synchronously, thereby keeping the axis of the pipe 11 horizontal.

[0054] Reference Figure 1 The second winding mechanism 14 includes a second motor 141, and the output end of the second motor 141 is connected to a winding roller for winding the second pull rope 142.

[0055] The second motor 141 drives the corresponding take-up roller to rotate, which can wind or unwind the corresponding second pull rope 142, thereby adjusting the position of the support frame 10 in the horizontal direction.

[0056] Reference Figure 1 and Figure 2 Two slide rails 61 are fixedly mounted on the fixed plate 4, with the length direction of the slide rails 61 parallel to the axis of the pipe 11. The drive mechanism 6 includes two first rollers 63 and two second rollers 64 rotatably mounted on the sliding plate 7, with each roller 63 and roller 64 slidingly adapted to its corresponding slide rail 61. A rotating shaft 62 is coaxially fixed to the first roller 63, and a drive assembly for driving the rotating shaft 62 is provided on the sliding plate 7. Specifically, the drive assembly includes a drive motor 65 mounted on the sliding plate 7, with a transmission belt 66 tensioned and wrapped between the output end of the drive motor 65 and the rotating shaft 62.

[0057] When the drive motor 65 is started, the first roller 63 rotates under the transmission belt 66, thereby driving the sliding plate 7 to slide along the slide rail 61, realizing the horizontal movement of the sliding plate 7, and thus causing the pipe 11 to be installed to translate along its own axis and approach the installed pipe 11.

[0058] Reference Figure 3 and Figure 5 The auxiliary alignment mechanism 13 includes a disc 131 and four internally threaded sleeves 132 fixed to the periphery of the disc 131. The internally threaded sleeves 132 extend radially along the disc 131, and the length directions of two adjacent internally threaded sleeves 132 are perpendicular to each other. A first threaded rod 133 is threadedly connected to each internally threaded sleeve 132. An abutment plate 134 is rotatably connected to the end of the first threaded rod 133 away from the internally threaded sleeve 132. The abutment plate 134 is an arc-shaped plate adapted to the contour of the inner wall of the pipe 11. When the four abutment plates 134 abut against the inner wall of the pipe 11, the disc 131 is coaxial with the pipe 11. A sensing component is provided on the disc 131 to determine whether two discs 131 are coaxial.

[0059] Furthermore, referring to Figure 5 A level 137 is mounted in the center of the disk 131, and the length direction of the level 137 is parallel to the length direction of two of the internal threaded sleeves 132. The sensing assembly includes an infrared device 135 mounted on the disk 131. When the two pipes 11 are connected, the infrared device 135 in the auxiliary alignment mechanism 13 in one pipe 11 is an infrared transmitter, and the infrared device 135 in the auxiliary alignment mechanism 13 in the other pipe 11 is an infrared receiver. The positions of the infrared transmitter and the infrared receiver on the disk 131 correspond to each other.

[0060] Auxiliary alignment mechanisms 13 are installed in the two pipes 11 that need to be connected. During installation, the four first threaded rods 133 are rotated so that the four arc-shaped abutment plates 134 abut against the inner wall of the pipe 11. At this time, the disc 131 is coaxial with the pipe 11. During the installation of the auxiliary alignment mechanism 13, the installation angle of the auxiliary alignment mechanism 13 is adjusted. When the bubble in the level 137 is in the middle of the level 137, it indicates that the two internal threaded sleeves 132 in the auxiliary alignment mechanism 13 are horizontal. This ensures that the installation angle of the auxiliary alignment mechanism 13 in the two pipes 11 is the same.

[0061] Furthermore, referring to Figure 5 A sensor light 136 is installed on the disc 131, and the sensor light 136 is connected to an infrared receiver.

[0062] During the process of adjusting the position of the pipe 11 through the first winding mechanism and the second winding mechanism 14, when the infrared light emitted by the infrared emitting device in one pipe 11 is received by the infrared receiving device in the other pipe 11, the sensor light 136 lights up, indicating that the discs 131 in the two pipes 11 are coaxial, that is, the two pipes 11 are coaxial, thus completing the positioning of the pipe 11.

[0063] Subsequently, the sliding plate 7 is driven to move horizontally by the drive mechanism 6, so that the pipe to be installed 11 moves closer to the installed pipe 11 along its own axis. During this process, the alignment of the two pipes 11 is observed in real time by the infrared device 135 and the sensor light 136. If necessary, the length of each second pull rope 142 can be adjusted by the second winding mechanism 14 to make fine adjustments to the position of the support frame 10, so that the two pipes 11 always remain aligned until the two pipes 11 are connected.

[0064] The auxiliary alignment mechanism 13 can be disassembled and removed after the pipe 11 is connected and can be reused.

[0065] Reference Figure 1 The base 1 has a support mechanism 2 at its bottom for fixing it to the ground. Specifically, the base 1 has four rotatable wheels 21 at its bottom, and at least two hydraulic push rods 22 are arranged around each wheel 21 at the bottom of the base 1. The output end of the hydraulic push rod 22 is fixed to a support foot 23.

[0066] The casters 21 facilitate the movement of the device. During the positioning and docking of the pipe 11, the output end of the hydraulic push rod 22 extends to allow the support foot 23 to abut against the ground, fixing the base 1 to the ground, thereby improving the stability of the device, reducing device offset, and thus improving the accuracy of pipe 11 positioning.

[0067] Reference Figure 1 A support plate 15 is fixedly connected to the base 1, and a storage battery 16, a toolbox 17, and an electrical control cabinet 18 are installed on the support plate 15. The storage battery 16 provides power to the motors and other drive components in this device, and the electrical control cabinet 18 is used to control the start and stop of each drive component.

[0068] The implementation principle of a stabilizing support device for auxiliary positioning in municipal pipeline construction according to an embodiment of this application is as follows: The pipe 11 to be installed is placed on two support frames 10. The first winding mechanism winds or unwinds the first pull rope 9 to raise or lower the support frame 10, thereby adjusting the position of the pipe 11 in the vertical direction. The second winding mechanism 14 winds or unwinds the second pull rope 142 to adjust the position of the pipe 11 in the horizontal direction. The auxiliary alignment mechanism 13 aligns the axis of the pipe 11 to be installed with the axis of the installed pipe 11. Then, the drive mechanism 6 drives the sliding plate 7 to move horizontally, so that the pipe 11 to be installed moves closer to the installed pipe 11 along its own axis. During this process, the second winding mechanism 14 winds or unwinds each of the second pull ropes 142, thereby adaptively adjusting the length of each of the second pull ropes 142 during the translation of the pipe 11. This enables the positioning and connection of the pipe 11, improving the efficiency of pipe 11 installation.

[0069] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
