Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, and in particular to an auxiliary device for laying pipelines in municipal engineering and its usage method. Background Technology

[0002] Municipal engineering generally refers to the construction of various public transportation facilities, water supply, drainage, gas supply, urban flood control, environmental sanitation, and lighting infrastructure in urban development. Municipal engineering is an indispensable material foundation for urban survival and development, and a basic condition for improving people's living standards and opening up to the outside world. Municipal engineering construction requires the laying of pipelines, which involves assembling multiple sections of pipeline for use.

[0003] Patent CN219796347U discloses an auxiliary device for laying pipelines in trenches in municipal engineering. It includes a support base placed at the bottom of the trench, a fixed vertical plate fixedly mounted on the upper part of the support base, and adjustable support components for supporting the pipeline on both sides of the fixed vertical plate. Each of the adjustable support components includes an adjusting rod with one end hinged to the fixed vertical plate and the other end height adjustable. A rotatable rotating shaft is sleeved around the outer periphery of the adjusting rod. The two rotating shafts rotate with the two adjusting rods about the hinge point between the adjusting rod and the fixed vertical plate as the center. The end of the adjusting rod away from the fixed vertical plate is fixed in height after rotation, and the two rotating shafts jointly support the outer wall of the pipeline. However, existing pipeline assembly often uses fixed supports, which only provide simple positioning of the pipeline. When the pipeline is connected to other pipelines, the rotation and adjustment operations need to be performed manually. Furthermore, due to the frequent changes in the site of municipal construction, the positioning of the supports themselves requires frequent bolt removal and installation, making the operation cumbersome. Summary of the Invention

[0004] This invention proposes an auxiliary device for laying pipelines in municipal engineering and its usage method, which solves the problems of the supports used in the pipeline assembly of the prior art, which can only achieve simple positioning of the pipeline, and the adjustment of the pipeline itself is difficult. Moreover, the assembly of the pipeline supports is not simple and convenient due to the changes in the construction site.

[0005] The technical solution of this invention is implemented as follows: An auxiliary device for laying pipelines in municipal engineering includes a support base and a load-bearing limiting component. The support base is equipped with a limiting mechanism I for fixing the support base, and the limiting mechanism I is connected to the load-bearing limiting component. The load-bearing limiting component is equipped with a limiting mechanism II for fixing the load-bearing limiting component, and the limiting mechanism II is detachably connected to the support base. The load-bearing limiting component is equipped with a drive wheel that cooperates with the pipeline. The support base provides support for the load-bearing limiting component, and the load-bearing limiting component provides support for the pipeline. When the pipeline is placed on the load-bearing limiting component, the limiting mechanism I limits and fixes the support base, and the limiting mechanism II limits and fixes the load-bearing limiting component, thereby ensuring the stability of the support base and the load-bearing limiting component. The drive wheel can drive the pipeline to rotate on the load-bearing limiting component, facilitating pipeline adjustment.

[0006] The load-bearing limiting component is equipped with a buffer component located between the support base and the load-bearing limiting component. A guide component is located between the support base and the load-bearing limiting component. The buffer component provides cushioning protection during pipe placement to prevent impacts. The guide component is positioned directly below the load-bearing limiting component. During the up-and-down movement of the load-bearing limiting component, the guide component guides and supports the load-bearing component, making its movement more stable.

[0007] The bearing and limiting assembly includes a bearing plate with a second connecting hole. A drive wheel is rotatably disposed within the second connecting hole and extends out of the inner surface of the arc-shaped plate. The pipe is placed on the bearing plate, and the drive wheel contacts the outer wall of the pipe. The rotation of the drive wheel causes the pipe to rotate.

[0008] The support plate is an arc-shaped plate, and a cleaning brush is arranged along the axial direction of the arc-shaped plate on the support plate. Drop holes are provided on both sides of the cleaning brush, and a collection frame corresponding to the drop holes is provided on the support plate. During the rotation of the pipeline, the cleaning brush cleans the dirt on the pipeline surface, and the cleaned debris falls into the collection frame.

[0009] The limiting mechanism I includes a guide rod and a rotating rod. The support base has a laterally positioned movable hole. The guide rod is movably disposed within the movable hole, with one end hinged to the rotating rod and the other end hinged to the bearing plate. When the bearing plate moves up and down, the rotating rod drives the guide rod to move back and forth within the movable hole, thereby achieving the limiting, fixing, and unlocking of the support base.

[0010] A guide sleeve is provided inside the movable hole, and a guide rod is slidably connected to the guide sleeve. A movable block is provided on the guide rod, and the movable block is slidably engaged with the movable hole. A first elastic component is provided between the movable block and the guide sleeve. When the pipe is removed from the support plate, the first elastic component can infer the movement of the movable block, thereby causing the guide rod to retract and reset, thus canceling the limiting and fixing of the guide rod on the support seat.

[0011] The limiting mechanism II includes a moving rod and a connecting groove, which are detachably connected. The upper end of the moving rod is connected to a support plate, and a first groove is provided at the upper end of the moving rod. An elastic control component is provided in the first groove. A first connecting hole is provided on the support plate at the position corresponding to the movable limiting device, and the elastic control component passes upward through the first connecting hole. The contact state between the pipe and the support plate controls the action of the elastic control component, thereby controlling the connection state between the moving rod and the connecting groove, realizing the disconnection or connection between the moving rod and the connecting groove.

[0012] The movable rod has a second groove on its side, and a movable limiting block is slidably connected within the second groove. A second elastic component is provided between the movable limiting block and the bottom of the second groove. A limiting groove is provided on the side of the connecting groove. The movable limiting block and the limiting groove are detachably connected. The elastic control component is linked with the movable limiting block. A slope is provided on the lower side of the movable limiting block. The slope facilitates the movable limiting block being squeezed and moved by the connecting groove when it moves downward, which facilitates the insertion of the movable rod into the connecting groove. When the movable limiting block extends out of the second groove, the movable limiting block and the limiting groove cooperate to fix the relative position of the movable rod and the connecting groove, thereby achieving a fixed connection between the bearing plate and the support base.

[0013] The elastic control component includes a sliding contact rod, a sliding sleeve within a first groove, and the sliding contact rod slidably connected to the sliding sleeve. A limiting ring is provided on the sliding contact rod, and a third elastic component is provided between the limiting ring and the sliding sleeve. The upper end of the sliding contact rod passes through a first connecting hole, and the lower end of the sliding contact rod is connected to a magnetic block I. The movable limiting block is a magnetic block II, and magnetic blocks I and II have the same magnetic poles. There is a mutual repulsive magnetic force between magnetic blocks I and II, which pushes magnetic block II out of the second groove, connecting magnetic block II to the limiting groove, thereby achieving the connection between the movable rod and the connecting groove.

[0014] A method of using the aforementioned auxiliary device for laying pipelines in municipal engineering projects includes the following steps: During pipe assembly, the support base is placed directly into the pre-set slot for pipe placement. Then, the corresponding support plate is lowered, and the weight of the pipe presses against the support plate. The support plate drives the rotating rod, which in turn presses against the guide rod, inserting it into the side wall of the pre-set slot, thus limiting the support base. As the support plate moves downward, it compresses and shortens the buffer assembly, cushioning the pipe's descent. Simultaneously, the downward movement of the support plate compresses the sliding contact rod, causing it and magnetic block I to move downward. The moving rod, following the support plate's movement, inserts into the connecting slot. When the moving limit block reaches the limit slot position, the magnetic force between magnetic block I and the moving limit block drives the moving limit block into the limit slot, thus limiting the support plate. The drive wheel rotates the pipe, and as the pipe rotates, a cleaning brush wipes away dirt from the pipe surface. Debris falling through the drop hole enters the collection frame, after which the pipe can be assembled. After the adjacent pipes are assembled, the pipes are directly removed upwards. The pressure of the pipes on the sliding contact rod disappears. The third elastic component drives the sliding contact rod and magnetic block I to move upwards. The magnetic force between magnetic block I and the moving limit block disappears. The second elastic component drives the moving limit block to move into the second groove. At this time, the moving limit block separates from the limit groove. The buffer component drives the bearing plate to reset upwards. At this time, the rotating rod moves and pulls the guide rod to separate from the soil, thus canceling the limit of the support seat.

[0015] The beneficial effects of this invention are as follows: the support base provides support for the load-bearing limiting component, the load-bearing limiting component provides support for the pipeline, the pipeline is placed on the load-bearing limiting component, the limiting mechanism I limits and fixes the support base, and the limiting mechanism II limits and fixes the load-bearing limiting component, thereby ensuring the stability of the support base and the load-bearing limiting component; the drive wheel can drive the pipeline to rotate on the load-bearing limiting component, which facilitates the adjustment of the pipeline.

[0016] This invention, by setting up a support plate, a rotating rod, a guide rod, a first elastic component, and a buffer component, allows the pipe to be placed directly on the support plate. The buffer component cushions and protects the pipe during placement, preventing impact. Simultaneously, the pipe uses its own weight to compress the support plate and the rotating rod. As the support plate moves, the rotating rod compresses the guide rod, which automatically inserts into the soil on both sides of the pre-set groove, achieving automatic and rapid positioning of the support base. This makes the pipe assembly operation safer, the support base more stable during use, and the operation simpler. This invention comprises a movable rod, a movable limiting block, a magnetic block, a third elastic component, a fourth elastic component, and a limiting groove. When the sliding contact rod is pressed by the pipe, the magnetic block moves closer to the movable limiting block, controlling the movable limiting block to extend out of the second groove. As the movable rod moves downward, the movable limiting block inserts into the limiting groove, thus limiting the bearing plate and keeping it stable relative to the support. After the pipe separates from the bearing plate, the sliding contact rod is driven upward by the third elastic component, and the magnetic block moves away from the movable limiting block. As the magnetic force decreases, the second elastic component drives the movable limiting block to move into the second groove and separate from the limiting groove. At this point, the bearing plate is released from its limiting position, and the buffer component controls the bearing plate to automatically return to its original position.

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

[0020] Example 1, as Figures 1-7As shown, an auxiliary device for laying pipelines in municipal engineering includes a support base 1 and a load-bearing limiting component 6. The support base 1 is provided with a limiting mechanism I5 for fixing the support base 1, and the limiting mechanism I5 is connected to the load-bearing limiting component 6. The load-bearing limiting component 6 is provided with a limiting mechanism II7 for fixing the load-bearing limiting component 6, and the limiting mechanism II7 is detachably connected to the support base 1. The load-bearing limiting component 6 is provided with a drive wheel 67 that cooperates with the pipeline. The support base 1 provides support for the load-bearing limiting component 6, and the load-bearing limiting component 6 provides support for the pipeline. When the pipeline is placed on the load-bearing limiting component 6, the limiting mechanism I5 limits and fixes the support base 1, and the limiting mechanism II7 limits and fixes the load-bearing limiting component 6, thereby ensuring the stability of the support base 1 and the load-bearing limiting component 6. The drive wheel 67 can drive the pipeline to rotate on the load-bearing limiting component 6, which facilitates the adjustment of the pipeline.

[0021] Furthermore, such as Figure 3 As shown, the load-bearing limiting component 6 is equipped with a buffer component 8, which is located between the support base 1 and the load-bearing limiting component 6. A guide component 9 is provided between the support base 1 and the load-bearing limiting component 6. The buffer component 8 is a compression spring. Two buffer components 8 are provided on the outside of the load-bearing limiting component 6. During the pipeline lowering process, the buffer components 8 provide cushioning to prevent collision between the load-bearing limiting component 6 and the support base 1, ensuring safety in use. In addition, the guide component 9 includes a telescopic inner rod and a telescopic outer rod that are slidably connected to each other. The telescopic inner rod is fixedly connected to the load-bearing limiting component 6, and the telescopic outer rod is fixedly connected to the support base 1. The guide component 9 is arranged vertically. When the pipeline is lowered, the telescopic inner rod retracts into the telescopic outer rod. The cooperation of the telescopic inner rod and the telescopic outer rod guides the movement of the load-bearing limiting component 6, ensuring the movement stability of the load-bearing limiting component 6, and thus ensuring the safety of the auxiliary device in use.

[0022] Example 2, based on Example 1, provides an auxiliary device for municipal engineering pipeline laying, such as... Figure 4 As shown, the bearing limiting assembly 6 includes a bearing plate 61 with a second connecting hole 64. A drive wheel 67 is rotatably disposed within the second connecting hole 64 and extends out of the inner surface of the arc-shaped plate. A drive motor is mounted on the bearing plate 61, and the output end of the drive motor is connected to the drive wheel 67, which drives the drive wheel to rotate. The pipe is placed on the bearing plate 61, and the drive wheel 67 contacts the outer wall of the pipe. The rotation of the drive wheel 67 can drive the pipe to rotate.

[0023] Furthermore, such as Figure 4As shown, the support plate 61 is an arc-shaped plate, and a cleaning brush 66 is arranged along the axial direction of the arc-shaped plate on the support plate 61. Drop holes 63 are provided on both sides of the cleaning brush 66, and a collection frame 65 corresponding to the drop holes 63 is provided on the support plate 61. The cleaning brush 66 is located in the middle of the arc-shaped plate. When the drive wheel 67 drives the pipe to rotate, the cleaning brush 66 cleans the outer wall of the pipe, and the debris swept down falls into the collection frame 65 through the drop holes. Since both sides of the cleaning brush 66 have drop holes 63, the debris swept down by the cleaning brush 66 can fall into the collection frame 65 whether the pipe rotates clockwise or counterclockwise, thus achieving the cleaning and collection of debris.

[0024] Furthermore, such as Figure 2 , Figure 5 As shown, the limiting mechanism I5 includes a guide rod 52 and a rotating rod 56. The support base 1 has a horizontally arranged movable hole 4. The guide rod 52 is movably disposed within the movable hole 4. One end of the guide rod 52 is hinged to the rotating rod 56, and the other end of the rotating rod 56 is hinged to the support plate 61. Specifically, the rotating rod 56 is connected to the guide rod 52 via a first pin assembly 55, and the rotating rod 56 is hinged to the support plate 61 via a second pin assembly 57. During the up-and-down movement of the support plate 61, the rotating rod 56 drives the guide rod 52 to move back and forth within the movable hole 4. That is, when the support plate 61 descends, the guide rod 52 extends out of the movable hole 4; when the support plate 61 rises, the guide rod 52 retracts into the movable hole 4. In this embodiment, the support plate 61 is provided with two limiting mechanisms I5, which are symmetrically arranged on both sides of the cleaning brush 66 to ensure that the support plate 61 is subjected to uniform force during the lifting and lowering process. In addition, the end of the guide rod 52 is provided with a tapered head, which makes it easier for the guide rod 52 to fix the support base 1.

[0025] Furthermore, a guide sleeve 51 is provided inside the movable hole 4, and a guide rod 52 is slidably connected to the guide sleeve 51. A movable block 53 is provided on the guide rod 52, and the movable block 53 is slidably engaged with the movable hole 4. A first elastic component 54 is provided between the movable block 53 and the guide sleeve 51. The guide sleeve 51 guides the movement of the guide rod 52, and the cooperation between the moving block 53 and the moving hole 4 also guides the movement of the guide rod 52. The two work together to ensure the accuracy of the direction of movement of the guide rod 52 within the moving hole 4. In addition, the first elastic component 54 is a compression spring. When the pipe is placed on the support plate 61, the support plate 61 presses down, and the support plate 61 pushes the guide rod 52 out of the moving hole 4 and into the soil through the rotating rod 56. At this time, the moving block 53 and the guide sleeve 51 compress the compression spring. When the pipe is removed from the support plate 61, the support plate 61 moves up, and the moving block 53 returns to its original position under the action of the compression spring, canceling the insertion of the guide rod 52 into the soil, and thus canceling the limiting and fixing of the support base 1.

[0026] Example 3, based on Example 2, provides an auxiliary device for municipal engineering pipeline laying, such as... Figure 6 As shown, the limiting mechanism II 7 includes a moving rod 71 and a connecting groove 2, which are detachably connected. The upper end of the moving rod 71 is connected to the support plate 6, and a first groove 72 is provided at the upper end of the moving rod 71. An elastic control component 76 is provided in the first groove 72. A first connecting hole 62 is provided on the support plate 61 at the position corresponding to the movable limiting device 7, and the elastic control component 76 passes upward through the first connecting hole 62. When the support plate 61 moves downward, the moving rod 71 inserts downward into the connecting groove 2, realizing the connection between the support plate 61 and the support base 1. At the same time, when the pipe contacts the support plate 61, the pipe drives the elastic control component 76 to move.

[0027] Furthermore, the side of the moving rod 7 is provided with a second groove 73, and a moving limit block 75 is slidably connected in the second groove 73. A second elastic component 74 is provided between the moving limit block 75 and the bottom of the second groove 73. A limit groove 3 is provided on the side of the connecting groove 2. The moving limit block 75 and the limit groove 3 are detachably connected. The elastic control component 76 is linked with the moving limit block 75. A slope is provided on the lower side of the moving limit block 75. The second elastic component 74 is a tension spring. After the pipe is placed on the support plate 61, the pipe drives the elastic control component 76 to move, thereby causing the movable limiting block 75 to extend out of the second groove 73. The support plate 61 continues to move downward, and the inclined surface of the movable limiting block 75 cooperates with the connecting groove 2, causing the movable limiting block 75 to retract into the second groove 73. When the movable limiting block 75 reaches the position of the limiting groove 3, the movable limiting block 75 extends out of the second groove 73, realizing the connection between the movable limiting block 75 and the limiting groove 3, and connecting the moving rod 7 with the connecting groove 2, thereby fixing the relative position between the support plate 61 and the support seat 1, ensuring the stability of the load-bearing plate 61 during the use of the auxiliary device. When the pipe is removed from the support plate 61, the elastic control component 76 releases the support of the movable limiting block 75, causing the movable limiting block 75 to retract into the second groove 73 under the action of the tension spring, thereby separating the moving rod 7 from the connecting groove 2.

[0028] Furthermore, such as Figure 7As shown, the elastic control component 76 includes a sliding contact rod 762, a sliding sleeve 761 is provided in the first groove 72, the sliding contact rod 762 is slidably connected to the sliding sleeve 761, a limiting ring is provided on the sliding contact rod 762, and a third elastic component 764 is provided between the limiting ring and the sliding sleeve 761; the upper end of the sliding contact rod 762 passes through the first connecting hole 62, and the lower end of the sliding contact rod 762 is connected to a magnetic block I 763. The movable limiting block 75 is a magnetic block II, and the magnetic poles of magnetic block I 763 and magnetic block II are the same. The third elastic component 764 is a compression spring. Magnetic block I 763 and magnetic block II have the same magnetism, meaning there is a repulsive force between them. Under the action of this repulsive force, the movable limiting block 75 can be pushed out of the second groove 73. Specifically, when the pipe is removed from the support plate 61, the pipe separates from the upper end of the sliding contact rod 762, canceling the limitation on the sliding contact rod 762. The sliding contact rod 762 returns to its original position under the action of the compression spring, that is, the sliding contact rod 762 returns to the state of extending upwards out of the support plate 61. At this time, the repulsive force between magnetic block I 763 and magnetic block II decreases or disappears, and magnetic block II retracts into the second groove 73 under the action of the tension spring.

[0029] In addition, the upper end of the sliding contact rod 762 has a rounded head structure, which prevents damage to the outer wall of the pipe when the pipe contacts the upper end of the sliding contact rod 762, thus protecting the pipe. At the same time, the rounded head structure makes it easier for the pipe to slide, preventing the outer wall of the pipe from jamming the upper end of the sliding contact rod 762 and avoiding breakage of the sliding contact rod 762. In this embodiment, the moving rod 7 is provided with two symmetrically arranged second grooves 73, and each second groove 73 is slidably connected to a moving limit block 75. When the auxiliary device is in use, the two moving limit blocks 75 are connected together to the limit groove 3 on the connecting groove 2 to ensure the stability of the connection between the moving rod 7 and the connecting groove 2.

[0030] Example 4, based on Example 3, provides an auxiliary device for municipal engineering pipeline laying. The lower end of the sliding contact rod 762 has a V-shaped structure, which engages with the tail end of the movable limiting block 75. Specifically, when the sliding contact rod 762 moves downward, the V-shaped structure pushes the movable limiting block 75 out of the second groove 73, thus connecting the movable limiting block 75 with the limiting groove 3. In this example, in the initial state of the auxiliary device, the lower end of the moving rod 762 extends into the connecting groove 2, and the movable limiting block 75 is located in the second groove. Above 73, after the pipe is placed on the bearing plate 61, the bearing plate 61 moves downward under force until the moving limit block 75 corresponds to the position of the limit groove 3. At this time, the moving limit block 75 extends out of the second groove 73 and connects with the limit groove 3 under the action of the V-shaped structure at the lower end of the slide contact rod 762, realizing the connection between the moving limit block 75 and the limit groove 3, so that the moving rod 7 connects with the connecting groove 2, thereby realizing the relative position fixation between the bearing plate 61 and the support seat 1, ensuring the stability of the bearing plate 61 during the use of the auxiliary device.

[0031] Example 5, based on Example 3, provides a method for using the auxiliary device for laying pipelines in municipal engineering, comprising the following steps: During pipe assembly, the support base 1 is placed directly into the pre-set slot for pipe placement. Then, the corresponding support plate 61 is lowered. The weight of the pipe presses against the support plate 61, causing the rotating rod 56 to move. The rotating rod 56 presses against the guide rod 52, which then inserts into the side wall of the pre-set slot, thus limiting the position of the support base 1. Simultaneously, the downward movement of the support plate 61 compresses and shortens the buffer assembly 8, buffering the pipe lowering process. Furthermore, the downward movement of the support plate 61 compresses the sliding contact rod 762, causing the sliding contact... Rod 762 and magnetic block I 763 move downwards. Moving rod 71 moves downwards and inserts into connecting groove 2 along with the movement of bearing plate 61. When moving limit block 75 moves to the position of limit groove 3, the magnetic force between magnetic block I 763 and moving limit block 75 drives moving limit block 75 into limit groove 3, completing the limitation of bearing plate 61. Drive wheel 67 drives pipe to rotate. As pipe rotates, cleaning brush 66 cleans and wipes dirt on pipe surface. Falling debris enters collection frame 65 through drop hole 63, and then pipe can be assembled. After the adjacent pipes are assembled, the pipes are directly removed upwards. The pressure of the pipes on the sliding contact rod 762 disappears. The third elastic component 764 drives the sliding contact rod 762 and the magnetic block I 763 to move upwards. The magnetic force between the magnetic block I 763 and the moving limit block 75 disappears. The second elastic component 74 drives the moving limit block 75 to move into the second groove 73. At this time, the moving limit block 75 separates from the limit groove 3. The buffer component 8 drives the bearing plate 61 to reset upwards. At this time, the rotating rod 56 moves and pulls the guide rod 52 to separate from the soil, and the limit of the support seat 1 is canceled.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

6. A method of using an auxiliary device for laying municipal engineering pipelines as described in any one of claims 1 to 5, characterized in that, Includes the following steps: When assembling the pipe, the support base (1) is placed directly in the pre-set slot for pipe placement, and then the corresponding bearing plate (61) is lowered. The weight of the pipe presses against the bearing plate (61), and the bearing plate (61) drives the rotating rod (56) to move. The rotating rod (56) presses against the guide rod (52) to move. The guide rod (52) is inserted into the side wall of the pre-set slot, completing the limiting of the support base (1). While the bearing plate (61) moves downward, it presses against the buffer assembly (8) to shorten, thus buffering the pipe lowering process. While the bearing plate (61) moves downward, it presses against the sliding contact rod (762) to make the sliding contact rod (762)... 62) and magnetic block I (763) move downwards, and moving rod (71) moves downwards into connecting groove (2) along with the movement of bearing plate (61). When moving limit block (75) moves to the position of limit groove (3), the magnetic force between magnetic block I (763) and moving limit block (75) drives moving limit block (75) into limit groove (3) to complete the limit of bearing plate (61); drive wheel (67) drives pipe to rotate, and as pipe rotates, cleaning brush (66) cleans and wipes the dirt on pipe surface. The fallen debris enters collection frame (65) through drop hole (63), and then pipe can be assembled. After the adjacent pipes are assembled, the pipes are directly removed upwards. The pressure of the pipes on the sliding contact rod (762) disappears. The third elastic component (764) drives the sliding contact rod (762) and magnetic block I (763) to move upwards. The magnetic force between magnetic block I (763) and the moving limit block (75) disappears. The second elastic component (74) drives the moving limit block (75) to move into the second groove (73). At this time, the moving limit block (75) separates from the limit groove (3). The buffer component (8) drives the bearing plate (61) to reset upwards. At this time, the rotating rod (56) moves and pulls the guide rod (52) to separate from the soil, and the limit of the support seat (1) is canceled.
