Description

Technical Field

[0001] This invention relates to the field of pipeline installation technology, specifically to an installation device for drainage pipeline construction. Background Technology

[0002] Drainage pipelines refer to the systems of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater. This includes main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or elsewhere, any pipe that serves a drainage function should be counted as a drainage pipeline. Drainage pipelines are typically installed in foundation pits to save space and beautify the environment.

[0003] In the field of urban infrastructure construction, drainage pipeline systems are a key component ensuring the normal operation of cities, and their construction quality directly affects the effectiveness of urban flood control, drainage, and sewage treatment. With the continuous expansion of urban scale and the increasing complexity of underground pipe networks, the requirements for the construction efficiency and installation accuracy of drainage pipelines are becoming increasingly stringent.

[0004] Currently, traditional drainage pipe installation equipment generally relies on manual lifting or simple clamping and support methods to position the pipe ends. Manual lifting not only involves high labor intensity, high labor costs, and significant safety hazards, but also suffers from inconsistent installation quality due to difficulty in controlling operational precision, failing to meet the standardized construction standards of modern drainage projects. Meanwhile, simple clamping and support methods cannot adapt to changes in the center of gravity of drainage pipes of varying lengths, easily causing the pipe's center of gravity to deviate from the clamping center, resulting in poor stability of the installation device and severely affecting installation accuracy.

[0005] To address the aforementioned issues, this application presents an innovative installation device that can precisely adapt to drainage pipes of different diameters and lengths, achieving reliable support and fixation, and effectively solving existing technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide an installation device for drainage pipeline construction, solving the following technical problems: Currently, traditional drainage pipeline installation equipment generally relies on manual lifting or simple clamping and support methods to position the pipe installation ends. Manual lifting not only suffers from high labor intensity, high labor costs, and significant safety hazards, but also, due to the difficulty in controlling operational precision, results in inconsistent pipeline installation quality, failing to meet the standardized construction standards of modern drainage projects. Simple clamping and support methods, on the other hand, cannot adapt to changes in the center of gravity of drainage pipelines of different lengths, easily causing the pipeline's center of gravity to deviate from the clamping center, resulting in poor stability of the installation device and seriously affecting installation accuracy.

A third connecting rod is sleeved on one end of the second connecting rod. A fixing plate is connected to the upper end of the third connecting rod by fastening bolts. The upper end of the base is symmetrically provided with clamping components for clamping and fixing the installation end of the drainage pipe.

[0008] As a further aspect of the present invention: a plurality of threaded holes are provided on one side of the third connecting rod, and a fastener that is threadedly connected to the threaded hole is provided on the outer surface of the second connecting rod.

[0009] As a further aspect of the present invention, rubber pads are provided on the inner sidewalls of both fixing plates.

[0010] As a further aspect of the present invention: a sliding assembly is symmetrically arranged inside the base. The sliding assembly includes a second gear disposed in a through hole inside the base. The two ends of the second gear are meshed with toothed plates. Sliding rods are slidably arranged at both ends of the base. A moving rod is fixedly arranged between the sliding rod and the toothed plate. The upper end of the moving rod is fixedly connected to the lower end of the first connecting rod in the middle, so as to realize the reciprocating movement of the support assembly.

[0011] As a further aspect of the present invention: the bottom end of the through hole inside the base is symmetrically provided with slots, which are slidably engaged with the toothed plate and the sliding rod respectively.

[0012] As a further embodiment of the present invention: a lifting assembly is symmetrically arranged on the upper end of the base. The lifting assembly includes a bidirectional lead screw rotatably arranged on the upper end of the base. Sliding blocks are threaded to both ends of the bidirectional lead screw. Lifting rods are symmetrically rotatably connected to the upper ends of the two sliding blocks. The upper ends of the two lifting rods are connected to the same top plate. The top plate is connected to the clamping assembly.

[0013] As a further aspect of the present invention: the clamping assembly includes a plurality of positioning rods fixedly disposed on the upper end of the top plate, the upper ends of the plurality of positioning rods being fixedly disposed on the same clamping plate, the two ends of the clamping plate being threadedly connected to adjusting bolts, and one end of the adjusting bolts being rotatably connected to an arc-shaped plate.

[0014] As a further aspect of the present invention: support rods are symmetrically arranged on one side of the arc-shaped plate, and a support sleeve is movably sleeved at one end of the two support rods. A spring is sleeved on the outside of the support rods and fixed between the arc-shaped plate and the support sleeve.

[0015] As a further aspect of the present invention, the curvature of the arc-shaped frame is consistent with the curvature of the arc-shaped structure at the upper and lower ends of the clamping plate.

[0016] As a further aspect of the present invention: adjusting bolts are provided at the four corners of the lower end of the base, a base plate is provided at the lower end of the adjusting bolts, and a pin is fixedly connected to the lower end of the base plate.

[0017] The beneficial effects of this invention are: (1) This invention flexibly adjusts the relative distance between the support component and the installation position through a sliding component, adapting to the support and fixing of drainage pipes of different lengths; the height of the arc frame is adjusted by a combination of a threaded sleeve and a screw, while the shaft is driven to reciprocate by a hydraulic telescopic cylinder, and the first gear is rotated by the opposite direction of the screw thread, and then transmitted through the rotating rod, the second connecting rod and the third connecting rod, to achieve rapid rotation and clamping of the pipe on both sides by the fixing plate. Among them, the fastener can flexibly adjust the extension length of the second connecting rod to accurately adapt to the clamping requirements of pipes of different diameters. The overall structure is simple and ingenious, the operation is convenient and efficient, and there is no need for manual lifting of the pipe, which significantly reduces labor costs; compared with traditional manual operation, the pipe connection is more stable and less shaking, effectively improving construction efficiency and work quality.

With the help of the adjusting bolt to drive the arc plate to move, it can reliably clamp and fix the two drainage pipes on the side at the installation position. At the same time, the lifting component can make the clamping components on both sides present different heights, which can facilitate the rapid installation of corner bends and significantly improve the applicability of the installation device. The adjusting bolt can flexibly adjust the height of the base. Even on the uneven bottom of the ditch, the base can be kept horizontal by adjusting the bolt, which effectively enhances the stability and operational safety of the installation device.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature.

[0025] In the field of pipeline construction technology, the docking accuracy of installation devices for drainage pipeline construction is crucial to its installation quality and service life. Addressing the problems of low installation efficiency and poor docking accuracy in traditional pipeline installation devices, this invention provides an installation device for drainage pipeline construction that achieves efficient installation through a series of innovative designs. The specific implementation method is as follows: Example 1: As Figures 1-2 As shown, an installation device for drainage pipe construction includes a base 1, with support components 2 symmetrically arranged on the upper end of the base 1. Drainage pipes are relatively heavy, and during the installation process, they are prone to swaying after being lifted by workers, making it difficult to ensure that the drainage pipes are in a stable state. This makes it inconvenient to connect drainage pipes, thereby affecting the construction efficiency of drainage pipes. By supporting and fixing the middle part through the support components 2, it is easier to install quickly and improves installation efficiency and accuracy. The base 1 has symmetrically arranged sliding components 3 inside, which are connected to the support components 2. The sliding components 3 are used to adjust the position of the support components 2. During the installation of the drainage pipe, due to the difference in processing dimensions at both ends of each pipe section, the relative distance between its center of gravity and the installation position is not the same. By adjusting the position of the support components 2 through the sliding components 3, the operator can flexibly adjust the position of the support components 2 according to the specific length and center of gravity distribution of the drainage pipe to be installed, ensuring that the force center of the support components 2 and the center of gravity of the pipe are on the same vertical line. This design ensures that the drainage pipe always maintains a stable horizontal state during the installation process, effectively avoiding docking errors caused by pipe shaking and offset. This not only significantly improves the connection accuracy of the drainage pipe, but also greatly shortens the installation time and effectively improves the overall construction efficiency.

[0026] like Figures 2-4As shown, multiple sliding grooves are symmetrically formed on both sides of the upper end of the base 1. In this embodiment, there are three sliding grooves. The support assembly 2 includes multiple first connecting rods 201 slidably disposed in the sliding grooves at the upper end of the base 1. The upper end of the middle first connecting rod 201 is provided with a threaded sleeve 202. The threaded sleeve 202 is internally threaded with a screw 203. The upper end of the screw 203 is provided with an arc-shaped frame 204. A telescopic square sleeve is provided between the arc-shaped frame 204 and the first connecting rod 201 to limit the rotation of the arc-shaped frame 204. When the threaded sleeve 202 is rotated, the square sleeve rod limits the rotation of the screw 203. The arc-shaped frame 204 supports and fixes the non-installation end of the drainage pipe. The height of the arc-shaped frame 204 can be adjusted by the threaded sleeve 202 and the screw 203. The same connecting rod 205 is fixedly installed on the side of multiple first connecting rods 201. The lower end of the connecting rod 205 is spaced a certain distance from the upper end of the base 1 to avoid interference between their movements. A hydraulic telescopic cylinder 206 is installed at one end of the connecting rod 205. A shaft 207 is fixedly mounted at the end of the piston rod. The shaft 207 is movably mounted inside the connecting rod 205 and can reciprocate within the connecting rod 205. Symmetrically arranged at the upper end of the shaft 207 are threads 208 with opposite directions of rotation. The upper ends of the two threads 208 mesh with a first gear 209. A rotating rod 210 is fixedly mounted on the outer side of the first gear 209. Support plates 211 are fixedly mounted on the sides of both ends of the connecting rod 205. A connecting plate 212 is fixedly mounted at one end of the support plate 211. Rotary connection to rotating rod 210, second connecting rod 213 is fixedly sleeved on the outer surface of rotating rod 210, third connecting rod 214 is sleeved on one end of second connecting rod 213, multiple threaded holes 215 are opened on one side of third connecting rod 214, fasteners 216 are provided on the outer surface of second connecting rod 213 and threadedly connected to threaded holes 215, fasteners 216 can be fastening bolts, fixing plate 217 is connected to the upper end of second connecting rod 213 by fastening bolts, and rubber pad is provided on the end of fixing plate 217 away from second connecting rod 213; The extension length of the third link 214 relative to the second link 213 can be adjusted by fastener 216 engaging with threaded hole 215, facilitating the clamping and fixing of drainage pipes of different diameters. The second link 213 is connected to the fixing plate 217 by fastening bolts, allowing adjustment of the swing angle of the fixing plate 217 according to the diameter of the drainage pipe, maximizing the contact area between the fixing plate 217 and the pipe, thus improving clamping stability and safety. The rubber pad prevents the metal fixing plate 217 from directly contacting the pipe, preventing scratches, indentations, or coating damage to the pipe surface due to rigid compression. Simultaneously, the high friction of the rubber pad effectively prevents the pipe from sliding or shifting during clamping, making it particularly suitable for pipe fixing in vibrating environments.

[0027] like Figure 5As shown, the sliding assembly 3 includes a second gear 31 disposed in a through hole inside the base 1. The base 1 has a through hole, and the sliding assembly 3 is disposed in the through hole. The second gear 31 is driven to rotate by a servo motor at its lower end. The two ends of the second gear 31 are symmetrically meshed with toothed plates 32. The two ends of the base 1 are slidably disposed with sliding rods 33. The sliding rods 33 and the second gear 31 are on the same straight line. A moving rod 34 is fixedly disposed between the sliding rod 33 and the toothed plates 32. The upper end of the moving rod 34 is fixedly connected to the lower end of the middle first connecting rod 201. The upper ends of the toothed plates 32 and the sliding rod 33 on one side are respectively fixedly connected to the first connecting rods 201 symmetrically at both ends. The lower end of the moving rod 34 is spaced a certain distance from the base 1 to avoid interference during movement. The servo motor drives the second gear 31 to rotate, and the second gear 31 drives the two toothed plates 32 to move towards or away from each other. The toothed plates 32 drive the sliding rod 33 to slide inside the base 1 through the moving rod 34, and slide back and forth inside the base 1 through the first connecting rod 201 to adjust the distance between the support point and the installation position, so that the support point and the center of gravity of the drainage pipe are on the same vertical line, which is convenient to adapt to the support and fixation of pipes of different lengths and improves the stability of the support.

[0028] like Figure 5 As shown, the bottom end of the through hole inside the base 1 is symmetrically provided with slots 11. The slots 11 are T-shaped. The two slots 11 are slidably engaged with the toothed plate 32 and the sliding rod 33 respectively. The toothed plate 32 and the sliding rod 33 can slide inside the slots 11. The toothed plate 32 and the sliding rod 33 can be limited by the movable engagement of the slot 11, so that the toothed plate 32 and the sliding rod 33 do not deviate during the sliding process. At the same time, the T-shaped structure can engage the toothed plate 32 and the sliding rod 33 in position. The T-shaped structure can provide a stop constraint in the longitudinal (vertical direction), and transfer part of the longitudinal force to the support structure through the vertical surface of the T-shaped structure, instead of being completely borne by the root of the cantilever, thereby reducing the shear force of the cantilever and reducing the risk of shear failure of the toothed plate 32 and the sliding rod 33.

[0029] In summary, this drainage pipe installation device allows for the placement of the drainage pipe on the clamping plate 52 during use. The position of the support component 2 is then adjusted via the sliding component 3, ensuring that the center of gravity of the pipe is aligned with the center of the arc-shaped frame 204. The angle of the fixing plate 217 is adjusted using fastening bolts, and the extension length of the third connecting rod 214 is adjusted by the engagement of the fastener 216 with the threaded hole 215. This facilitates quick and easy support and fixation of drainage pipes of different diameters. After fixation, pipe installation can proceed. The overall structure is simple and ingenious, offering convenient and efficient operation. It eliminates the need for manual pipe lifting, significantly reducing labor costs. Compared to traditional manual operation, the device provides greater stability and less shaking during pipe connection, effectively improving construction efficiency and work quality.

[0030] Example 2: Based on Example 1, as follows Figure 6 As shown, a lifting assembly 4 is symmetrically arranged on the upper end of the base 1. The lifting assembly 4 is used to adjust the height of the clamping assembly 5. The lifting assembly 4 includes a bidirectional lead screw 41 symmetrically rotatably arranged on the upper end of the base 1. The bidirectional lead screw 41 is symmetrically rotatably arranged in a slot on the upper end of the base 1. It is driven to rotate by a servo motor at one end of the bidirectional lead screw 41. Both ends of the bidirectional lead screw 41 are threadedly connected to sliding blocks 42. The upper ends of the two sliding blocks 42 are symmetrically rotatably connected to lifting rods 43. The upper ends of the two lifting rods 43 are connected to the same top plate 44. The upper end of the top plate 44 is connected to the clamping assembly 5. A servo motor drives a bidirectional lead screw 41 to rotate, which in turn drives a sliding block 42 threadedly connected to the bidirectional lead screw 41 to move towards or away from each other. The sliding block 42 drives a lifting rod 43 to adjust the height of the top plate 44, thereby facilitating quick adjustment of the height of the clamping assembly 5. During docking installation, the flexible height adjustment enables precise docking of drainage pipes. At the same time, when docking bent pipes, the height of the two symmetrical clamping assemblies 5 can be adjusted to meet the height requirements of bent pipe docking, thereby quickly achieving the docking of bent drainage pipes and improving construction efficiency.

[0031] like Figures 6-7 As shown, a clamping assembly 5 is provided at the upper end of the base 1. The clamping assembly 5 includes multiple positioning rods 51 fixedly installed at the upper end of the top plate 44. The upper end of the multiple positioning rods 51 is fixedly provided with the same clamping plate 52. The arc structure at the upper and lower ends of the clamping plate 52 is consistent with the arc of the arc frame 204. Both ends of the clamping plate 52 are threaded with adjusting bolts 53. The adjusting bolts 53 are provided with handwheels on the outside of the clamping plate 52. One end of the adjusting bolts 53 is rotatably connected to an arc plate 54 on the inside of the clamping plate 52. The inside of the arc plate 54 is provided with a rubber pad. Support rods 55 are symmetrically provided on one side of the arc plate 54. One end of each of the two support rods 55 is movably sleeved with a support sleeve 56. The support sleeve 56 is fixedly connected to the inner wall of the clamping plate 52. A spring 57 is sleeved on the outside of the support rods 55 and fixed between the arc plate 54 and the support sleeve 56. The distance between the two arc-shaped plates 54 can be adjusted by turning the handwheel to clamp and fix the side wall of the drainage pipe, preventing shaking during docking. The support rod 55 can move within the support sleeve 56, and the spring 57 always applies elastic force to the arc-shaped plate 54, making the clamping more stable.

[0032] Adjusting bolts 61 are provided at the four corners of the lower end of the base 1. The height of the base 1 can be adjusted by adjusting the adjusting bolts 61. A base plate 62 is provided at the lower end of the adjusting bolts 61, and a pin 63 is fixedly connected to the lower end of the base plate 62.

[0033] In summary, during the installation of the drainage pipe, the top plate 44 connected to the sliding block 42 is moved by the double-acting screw 41 to adjust the height of the clamping assembly 5. The rotating adjusting bolt 53 moves the arc plate 54, which can fix the side of the drainage pipe at the installation end and improve the installation accuracy. In actual use, even on uneven ditch bottoms, the base 1 can be kept level by adjusting the bolt 61, effectively enhancing the stability and operational safety of the installation device.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
