Description

Technical Field

[0001] This utility model relates to the field of pipe section installation technology, and in particular to an auxiliary structure for installing circular culvert pipe sections. Background Technology

[0002] As a crucial drainage structure in road engineering, the core function of circular culverts is to efficiently guide water flow across the roadbed, preventing erosion, settlement, or instability caused by water scouring, thereby ensuring the safety of the road structure and the stability of the surrounding environment. The installation of pipe sections is the core step in the construction of circular culverts, and its construction quality directly determines the overall stability of the culvert, the smoothness of water flow, and the service life of the road.

[0003] For a long time, the installation of circular culvert pipe sections has generally adopted a rough construction process of "hoisting + manual correction". The specific process is as follows: after the culvert foundation construction is completed, the axis of the pipe section is determined by measurement and layout; the pipe section is hoisted to the foundation pad layer by crane or excavator, and roughly aligned by manual prying and mechanical assistance (such as truck crane or excavator pushing); the axis, elevation and joint width of the pipe section are adjusted manually, and temporary fixation is achieved by using stones and wooden wedges; after the above process is repeated to complete the installation of all pipe sections, the joints are filled with materials such as hemp to achieve waterproofing.

[0004] However, this traditional process has significant drawbacks, specifically: First, pipe section alignment relies heavily on manual prying and adjustment, requiring multiple workers to coordinate the operation. Machinery (such as cranes) only performs the lifting function, and the manual adjustment process is time-consuming and labor-intensive, resulting in a long installation time for each pipe section and extending the overall construction cycle. Second, during manual prying, workers must handle pipe sections weighing several tons at close range, posing risks of pipe slippage, mechanical misoperation, or crushing and collision injuries due to broken pry bars. These drawbacks lead to low construction efficiency and high safety risks in the traditional circular culvert installation process, making it difficult to meet the requirements of modern road engineering for standardized and efficient construction. Utility Model Content

[0005] The purpose of this invention is to provide an auxiliary structure for installing circular culvert sections, in order to solve the problems of high reliance on manual labor and high safety risks in traditional processes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An auxiliary structure for installing a circular culvert section includes: a movable support, an orientation adjustment component, and a hoisting component. The hoisting component is used to hoist the culvert. The hoisting component is connected to the orientation adjustment component, which is mounted on the movable support. The orientation adjustment component is configured to adjust the planar position of the hoisting component. The orientation adjustment component includes a first guide rail and a second guide rail. The first guide rail extends along a first direction, and the second guide rail is movably mounted on the first guide rail to allow the second guide rail to move along the first direction. The second guide rail extends along a second direction, and the hoisting component is movably mounted on the second guide rail to allow the hoisting component to move along the second direction. The first direction is perpendicular to the second direction.

[0008] Based on the aforementioned technical means, the orientation adjustment component in this utility model achieves precise displacement adjustment of the hoisting component in a plane through the perpendicular intersection design of the first guide rail (moving along the first direction) and the second guide rail (moving along the second direction). Operators only need to control the movement of the first and second guide rails (e.g., mechanical drive or manual adjustment) to complete the alignment of the pipe section's axis, elevation adjustment, and joint width control, significantly reducing manual labor such as prying and pushing. Simultaneously, the precision and speed of mechanical adjustment are far superior to manual operation, significantly shortening the installation time of a single pipe section, compressing the overall construction cycle, and fully utilizing the time efficiency of both manual and mechanical operations, fundamentally reducing reliance on manual labor.

[0009] This invention replaces manual prying with a mechanized orientation adjustment component, eliminating the need for direct contact with the pipe section. At the same time, the movable support provides stable support for the overall structure, and the pipe section is rigidly connected to the orientation adjustment component through the hoisting component, avoiding the unreliability of temporary fixing measures. This significantly reduces the risk of pipe section displacement and fundamentally ensures the safety of construction personnel.

[0010] Furthermore, the orientation adjustment component also includes a first connector, which is adapted to the first guide rail and configured to move along a first direction on the first guide rail; the first connector is connected to the end of the second guide rail.

[0011] According to the above technical means, the first connector is a dedicated connecting component between the second guide rail and the first guide rail. Its adaptation design with the first guide rail can ensure that there is no wobble or jamming when the second guide rail moves along the first direction.

[0012] Furthermore, the first connector includes a first roller and a first connecting seat, the first roller being rotatably mounted on the first connecting seat; the first roller is adapted to the first guide rail so that the first roller can move along a first direction on the first guide rail; the first connecting seat is connected to the second guide rail.

[0013] Based on the aforementioned technical means, the first roller adopts a rolling contact method to reduce motion resistance. The adaptation design between the first roller and the first guide rail (such as the roller groove matching the outer edge of the first guide rail) can achieve precise guidance, and the second guide rail moves without lateral wobble or longitudinal slippage.

[0014] Furthermore, the orientation adjustment assembly also includes a second connector, which is adapted to the second guide rail and configured to move along a second direction on the second guide rail; the second connector is connected to the hoisting assembly.

[0015] Based on the above technical means, the second connector serves as a dedicated connecting component between the hoisting assembly and the second guide rail. Its adaptation design with the second guide rail ensures that the hoisting assembly moves along the second direction without any swaying or jamming.

[0016] Furthermore, the second connector includes a second roller and a second connecting seat, the second roller being rotatably mounted on the second connecting seat; the second roller is adapted to the second guide rail so that the second roller can move along the second direction on the second guide rail; the second connecting seat is connected to the hoisting assembly.

[0017] Based on the aforementioned technical means, the second roller adopts a rolling contact method to reduce motion resistance. The adaptation design of the second roller and the second guide rail (such as the matching of the second roller groove with the outer edge of the second guide rail) can achieve precise guidance, and there is no lateral sway or longitudinal slippage when the hoisting component moves.

[0018] Furthermore, the hoisting assembly includes a hook, a hoisting rope, and a drive unit. The drive unit is mounted on the second connecting seat. One end of the hoisting rope is connected to the hook, and the other end is retractably mounted on the drive unit. The drive unit is used to retract / unretract the hoisting rope. The hook is used to connect to the culvert.

[0019] Based on the above technical means, the drive unit adopts an electric or manual winding design, and the winding and unwinding of the hoisting rope is controlled by forward and reverse rotation, which directly adjusts the vertical position of the hook and pipe section.

[0020] Furthermore, the hoisting assembly also includes a pulley block, which is mounted on the second connecting seat, and the other end of the hoisting rope passes around the pulley block and is mounted on the drive component.

[0021] Based on the above-mentioned technical means, the pulley block can change the direction of force on the hoisting rope, so that the installation position of the drive component is no longer limited to the vertical direction of the hoisting point. It can be flexibly arranged according to the actual spatial layout, reducing the site restrictions for equipment installation and improving structural adaptability.

[0022] By utilizing the force components of multiple suspension ropes, pulley blocks can effectively reduce the tension required by the drive components, lower the power demand of the drive components, and achieve energy saving and consumption reduction. At the same time, the synergistic effect of multiple suspension ropes can distribute the force on a single suspension rope, reduce the load on a single suspension rope, and extend the service life of the suspension rope and related components.

[0023] Furthermore, the pulley system includes at least two fixed pulleys.

[0024] Based on the above technical means, the combination of at least two fixed pulleys can form multiple guide paths, making the range of force direction adjustment of the suspension rope wider.

[0025] Furthermore, the movable support includes a frame, multiple legs, and multiple ratchet wheels, with each leg vertically supported below the frame; the orientation adjustment assembly and the hoisting assembly are both mounted on the frame; and each ratchet wheel is mounted on each of the legs.

[0026] Based on the above-mentioned technical means, multiple outriggers are vertically supported under the frame. By distributing the overall load through multi-point contact with the ground, the bearing capacity of a single outrigger is effectively reduced, avoiding the risk of the support tilting due to local soft or uneven ground. It is especially suitable for complex ground environments such as outdoors and construction sites, ensuring the foundation stability of the support during hoisting operations and providing reliable support for the precise operation of the orientation adjustment components and hoisting components.

[0027] Each ratchet is mounted on one of the outriggers, enabling the outriggers to lock to the ground. During hoisting operations, the ratchet effectively prevents the outriggers from accidentally sliding or shifting due to external forces or misoperation, avoiding safety accidents such as tilting or collision of the hoisted object caused by the displacement of the moving support, and significantly improving the safety of the hoisting process.

[0028] Furthermore, the movable support also includes multiple beam supports, each of which is supported at the connection between the leg and the frame.

[0029] Based on the above technical means, the beam support, as an independent support component, forms a triangular support structure with the contact surface of the support leg and the frame, which can distribute the concentrated load to a larger contact area and reduce the local stress at the connection.

[0030] The beneficial effects achieved by this utility model are:

[0031] The orientation adjustment component in this invention achieves precise displacement adjustment of the hoisting component within a plane through the perpendicular intersection design of the first guide rail (moving along the first direction) and the second guide rail (moving along the second direction). Operators only need to control the movement of the first and second guide rails (e.g., mechanical drive or manual adjustment) to complete the alignment of the pipe section's axis, elevation adjustment, and joint width control, significantly reducing manual labor such as prying and pushing. Simultaneously, the precision and speed of mechanical adjustment are far superior to manual operation, significantly shortening the installation time of a single pipe section, compressing the overall construction cycle, and fully utilizing the time efficiency of both manual and mechanical operations, fundamentally reducing reliance on manual labor.

[0032] This invention replaces manual prying with a mechanized orientation adjustment component, eliminating the need for direct contact with the pipe section. At the same time, the movable support provides stable support for the overall structure, and the pipe section is rigidly connected to the orientation adjustment component through the hoisting component, avoiding the unreliability of temporary fixing measures. This significantly reduces the risk of pipe section displacement and fundamentally ensures the safety of construction personnel. Attached Figure Description

[0049] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings.

[0050] like Figure 1As shown, an auxiliary structure for installing a circular culvert section includes: a movable support 1, an orientation adjustment component 2, and a hoisting component 3. The hoisting component 3 is used to hoist the culvert. The hoisting component 3 is connected to the orientation adjustment component 2, which is mounted on the movable support 1. The orientation adjustment component 2 is configured to adjust the planar position of the hoisting component 3. The orientation adjustment component 2 includes a first guide rail 21 and a second guide rail 22. The first guide rail 21 extends along a first direction, and the second guide rail 22 is movably mounted on the first guide rail 21 so that the second guide rail 22 can move along the first direction. The second guide rail 22 extends along a second direction, and the hoisting component 3 is movably mounted on the second guide rail 22 so that the hoisting component 3 can move along the second direction. The first direction is perpendicular to the second direction.

[0051] like Figure 2 As shown, the specific construction process is as follows:

[0052] Move the mobile support 1 to the starting end of the culvert foundation (such as the installation position of the first pipe section), tie the end of the hoisting component 3 to the preset hoisting point of the pipe section, slowly lift the pipe section off the ground, operate the mobile support 1 to move along the extension direction of the foundation pit, and move the pipe section to the approximate installation area above the foundation.

[0053] The second guide rail 22 is moved along the extension direction of the first guide rail 21 by pushing or by mechanical drive device, thereby driving the hoisting assembly 3 and the pipe section to move synchronously in the first direction (the longitudinal deviation between the center line of the pipe section and the foundation axis can be measured by laser rangefinder or tape measure with reference to the axis control points marked on the foundation surface).

[0054] The hoisting assembly 3 is moved along the extension direction of the second guide rail 22 by pushing or by mechanical drive, so that the hoisting assembly 3 and the pipe section move synchronously in the second direction to complete the pipe section position adjustment.

[0055] After the pipe section position is adjusted, lock the movable support 1 and tighten the connection device between the first guide rail 21 and the second guide rail 22, and between the second guide rail 22 and the hoisting component 3 in the orientation adjustment component 2; insert an adjustable support (such as a hydraulic jack or a wooden wedge) between the bottom of the pipe section and the foundation to further stabilize the pipe section and prevent displacement caused by subsequent operations.

[0056] In this embodiment, the orientation adjustment component 2 achieves precise displacement adjustment of the hoisting component 3 in a plane through the perpendicular intersection design of the first guide rail 21 (moving along the first direction) and the second guide rail 22 (moving along the second direction). Operators only need to control the movement of the first guide rail 21 and the second guide rail 22 (e.g., mechanical drive or manual adjustment) to complete the alignment of the pipe section's axis, elevation adjustment, and joint width control, significantly reducing manual labor such as prying and pushing. Simultaneously, the precision and speed of mechanical adjustment are far superior to manual operation, significantly shortening the installation time of a single pipe section, compressing the overall construction cycle, and fully utilizing the time efficiency of both manual and mechanical operations, fundamentally reducing reliance on manual labor.

[0057] In this embodiment, the mechanized orientation adjustment component 2 replaces manual prying, eliminating the need for direct contact with the pipe section. At the same time, the movable support 1 provides stable support for the overall structure, and the pipe section is rigidly connected to the orientation adjustment component 3 through the hoisting component 3, avoiding the unreliability of temporary fixing measures. This significantly reduces the risk of pipe section displacement and fundamentally ensures the safety of construction personnel.

[0058] like Figure 1 , Figure 2 and Figure 4 As shown, the orientation adjustment component 2 further includes a first connector 23, which is adapted to the first guide rail 21 and is configured to move along a first direction on the first guide rail 21; the first connector 23 is connected to the end of the second guide rail 22.

[0059] The first connector 23 serves as a dedicated connecting component between the second guide rail 22 and the first guide rail 21. Its adaptation design with the first guide rail 21 ensures that the second guide rail 22 moves along the first direction without any wobble or jamming.

[0060] like Figure 4 As shown, the first connector 23 includes a first roller 231 and a first connecting seat 232. The first roller 231 is rotatably mounted on the first connecting seat 232. The first roller 231 is adapted to the first guide rail 21 so that the first roller 231 can move along a first direction on the first guide rail 21. The first connecting seat 232 is connected to the second guide rail 22.

[0061] The first roller 231 uses a rolling contact method to reduce motion resistance. The adaptation design of the first roller 231 and the first guide rail 21 (such as the groove of the first roller 231 matching the outer edge of the first guide rail 21) can achieve precise guidance, and the second guide rail 22 moves without lateral wobble or longitudinal slippage.

[0062] In this embodiment, the first roller 231 has a groove that fits against the top of the first guide rail 21. The groove of the first roller 231 can be made of a high-friction coefficient material (such as a rubber coating or polyurethane elastomer) and contacts the metal surface of the first guide rail 21 (such as a steel guide rail) to ensure sufficient traction.

[0063] In this embodiment, the first connecting seat 232 and the end of the second guide rail 22 are rigidly connected (such as by welding or high-strength bolts), which can effectively bear the weight of the second guide rail 22 and the lifting assembly 3 (usually several tons), avoiding the problems of guide rail deformation and loose connection caused by long-term use.

[0064] To improve positioning accuracy, for example, an encoder or displacement sensor can be installed on the first roller 231 to monitor the movement distance of the second guide rail 22 in real time and transmit the data to the control system, thereby achieving automated control of positioning in the first direction. By combining this with an electric push rod or servo motor (not shown) to drive the first roller 231 to rotate, unmanned operation of pipe section installation can be further achieved.

[0065] like Figure 1 , Figure 2 and Figure 5 As shown, the orientation adjustment component 2 further includes a second connector 24, which is adapted to the second guide rail 22 and is configured to move along a second direction on the second guide rail 22; the second connector 24 is connected to the hoisting component 3.

[0066] The second connector 24 serves as a dedicated connecting component between the hoisting assembly 3 and the second guide rail 22. Its adaptation design with the second guide rail 22 ensures that the hoisting assembly 3 moves along the second direction without any swaying or jamming.

[0067] like Figure 5 As shown, the second connecting member 24 includes a second roller 241 and a second connecting seat 242. The second roller 241 is rotatably mounted on the second connecting seat 242. The second roller 241 is adapted to the second guide rail 22 so that the second roller 241 can move along the second direction on the second guide rail 22. The second connecting seat 242 is connected to the hoisting assembly 3.

[0068] The second roller 241 uses a rolling contact method to reduce movement resistance. The adaptation design of the second roller 241 and the second guide rail 22 (such as the groove of the second roller 241 matching the outer edge of the second guide rail 22) can achieve precise guidance, and there is no lateral sway or longitudinal slippage when the hoisting assembly 3 moves.

[0069] In this embodiment, the second connector 24 has a similar structure to the first connector 23, and the same structure will not be described in detail.

[0070] like Figure 1 , Figure 2 and Figure 6 As shown, the hoisting assembly 3 includes a hook 31, a hoisting rope 32, and a drive component 33. The drive component 33 is mounted on the second connecting seat 242. One end of the hoisting rope 32 is connected to the hook 31, and the other end is retractably mounted on the drive component 33. The drive component 33 is used to retract / release the hoisting rope 32. The hook 31 is used to connect to the culvert.

[0071] The drive unit 33 adopts an electric or manual winding design, and controls the winding and unwinding of the lifting rope 32 by forward and reverse rotation, directly adjusting the vertical position of the hook 31 and the pipe section.

[0072] For example, electric drive components (such as servo motors and reducers) can control the speed of rope winding and unwinding, and the height adjustment of pipe sections is highly accurate to meet the construction requirements of the foundation top surface elevation error; manual drive components (such as handles and gear sets) through torque-increasing design (such as torque-increasing ratio of 1:15) can easily complete the winding and unwinding of ropes with only one operator, adapting to emergency adjustments in power-free scenarios.

[0073] In this embodiment, the hook 31 can be U-shaped (e.g., ...). Figure 1 and Figure 2 (As shown) or snap-on design (not shown in the figure), which perfectly matches the preset lifting points of the pipe section. The contact surface can be equipped with anti-slip textures or rubber pads to increase the friction coefficient and prevent the pipe section from slipping during the lifting process.

[0074] like Figure 6 As shown, the hoisting assembly 3 also includes a pulley block 34, which is mounted on the second connecting seat 242, and the other end of the hoisting rope 32 passes around the pulley block 34 and is mounted on the drive member 33.

[0075] The pulley block 34 can change the direction of force on the hoisting rope 32, so that the installation position of the drive component 33 is no longer limited to the vertical direction of the hoisting point. It can be flexibly arranged according to the actual spatial layout, reducing the site restrictions for equipment installation and improving structural adaptability.

[0076] The pulley block 34, through the force of the multiple sections of the suspension rope 32, can effectively reduce the tension required by the drive component 33, reduce the power demand of the drive component 33, and achieve energy saving and consumption reduction. At the same time, the synergistic effect of the multiple sections of the suspension rope 32 can distribute the force on a single suspension rope 32, reduce the load on a single suspension rope 32, and extend the service life of the suspension rope 32 and related components.

[0077] like Figure 6 As shown, the pulley block 34 includes at least two fixed pulleys.

[0078] The combination of at least two fixed pulleys can form multiple guide paths, making the force direction of the suspension rope 32 more adjustable.

[0079] The symmetrical or evenly distributed design of two or more fixed pulleys in this embodiment (such as symmetrical installation along the second connecting seat 242 in the transverse or longitudinal direction) can make the tension of the lifting rope 32 on the second connecting seat 242 more evenly distributed, avoid local stress concentration caused by unilateral force, enhance the structural strength and stability of the second connecting seat 242, reduce the risk of structural deformation or loosening caused by uneven force, and thus improve the safety of the hoisting process.

[0080] like Figure 1 and Figure 2 As shown, the movable support 1 includes a frame 11, multiple legs 12 and multiple ratchet wheels 13, with each leg 12 vertically supported below the frame 11; the orientation adjustment component 2 and the hoisting component 3 are both mounted on the frame 11; and each ratchet wheel 13 is mounted on each of the legs 12.

[0081] Multiple outriggers 12 are vertically supported below the frame 11. By distributing the overall load through multi-point contact with the ground, the bearing capacity of a single outrigger is effectively reduced, avoiding the risk of the support tilting due to local soft or uneven ground. It is especially suitable for complex ground environments such as outdoors and construction sites, ensuring the foundation stability of the support during hoisting operations and providing reliable support for the precise operation of the orientation adjustment component 2 and the hoisting component 3.

[0082] Each ratchet 13 is installed on each outrigger 12, enabling the outrigger 12 to lock to the ground. During hoisting operations, the ratchet 13 effectively prevents the outrigger 12 from accidentally sliding or displacing due to external forces or misoperation, avoiding safety accidents such as tilting or collision of the hoisted object caused by the displacement of the moving support 1, and significantly improving the safety of the hoisting process.

[0083] like Figure 1 and Figure 2 As shown, in this embodiment, the ratchet 13 is mounted on each leg 12 via bearings. Figure 3 As shown, the ratchet 13 includes a pawl 131, a ratchet disc 132, a pawl paddle 133, and a spring 134. The operator manually moves the pawl paddle 133 on the side of the ratchet 13 (or drives it to rotate via a motor). The pawl paddle 133 abuts against the pawl 131. When moved, the pawl paddle 133 causes the pawl 131 to move away from the ratchet disc 132 (i.e., the teeth of the pawl 131 gradually disengage from the tooth grooves of the ratchet disc 132). At this time, the spring 134, fixed to the bearing, is compressed, storing elastic potential energy. When the pawl 131 is completely disengaged, the ratchet disc 132 releases its engagement constraint with the pawl, and the ratchet enters a rotatable state.

[0084] The ratchet 13 can be driven manually or by a motor. For example, in manual control, the operator directly pushes the frame 11 of the movable support 1, causing the ratchet 13 to roll on the ground, and the movable support 1 moves along the culvert foundation to the target position. Alternatively, in motor-driven operation, the motor is connected to the ratchet shaft via gears or a chain drive, and after starting, it drives the wheel to roll, achieving more precise displacement control (such as adjusting the movement distance through encoder feedback).

[0085] After the mobile support 1 is moved to the preset position for the culvert hoisting operation, the operator reverses the pawl lever 133 (or resets 133 via a motor reversing drive). The pawl lever 133 drives the pawl 131 to move towards the ratchet disc 132. The spring 134 gradually releases its stored elastic potential energy, pushing the teeth of the pawl 131 into the grooves of the ratchet disc 132. The pawl 131 and the ratchet disc 132 form a one-way meshing constraint. If the wheel attempts to rotate in the opposite direction due to external force, the pawl 131 will immediately lock the ratchet disc 132, preventing the wheel from rotating, thereby stabilizing the support in the target position.

[0086] like Figure 1 and Figure 2 As shown, the movable support 1 also includes a plurality of beam supports 14, each of which is supported at the connection between each of the legs 12 and the frame 11.

[0087] As an independent support component, the beam support 14 forms a triangular support structure with the contact surface of the support leg 12 and the frame 11, which can distribute the concentrated load to a larger contact area and reduce the local stress at the connection.

[0088] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
