Description

Technical Field

[0001] The invention relates to the technical field of construction grooving devices, in particular to a pipeline grooving device. Background Art

[0002] Water pipes or other pipelines need to be laid on the surface of cast-in-place concrete floor slabs. If the pipeline grooves are not pressed on the surface of the concrete floor slabs, the water pipes will be exposed after the floor decoration, causing subsequent water pipes or other pipelines to be compressed by the subsequent construction, which may easily cause pipeline rupture and affect the construction quality.

[0003] In the prior art, during the concrete pouring process, the groove water pipe is placed on the mold and then poured. After the concrete solidifies, the groove is formed. However, because the groove water pipe is not firmly fixed during the pouring process, it will move during the concrete pouring process, resulting in uneven groove spacing, poor groove forming quality, and poor appearance.

[0022] Positioning holes corresponding to the positioning bolts are formed in both the first connecting piece and the second connecting piece.

[0023] Further, an accommodation space is provided between the second connecting piece and the end of the pressure pipe;

[0024] The length of the accommodation space is equal to the width of the connecting seat, so as to enable butt-joint of two groups of pressure pipes.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0044] Prior art requires pre-grooving water pipes and pipelines when laying them on cast-in-place concrete slabs to prevent subsequent cracking caused by pressure during construction. Traditionally, grooved water pipes are secured to a mold before pouring. However, this inadequate fixation can lead to pipe displacement, resulting in uneven groove spacing, poor build quality, and an unpleasant appearance. For example, the impact of water flow during concrete vibration can easily cause the grooved device to shift, causing subsequent grooves to deviate beyond the permitted position.

[0045] To solve the above problems, it is necessary to develop a pipeline grooving device with adjustable spacing and firm fixation. Traditional grooving devices use an integral structure that cannot adapt to different spacing requirements, and the rigid connection makes the whole body easy to shift when the concrete is vibrated. Through analysis, it was found that the grooving device needs to have independent adjustable units, each of which can slide freely along the support structure and be locked individually. At the same time, it is necessary to ensure that each unit is stable and does not shift during the pouring process. Based on this, the grooving device is decomposed into modular units that can be slid and adjusted, and each unit is equipped with an independent locking mechanism to form a multi-point positioning structure.

[0046] Therefore, if Figure 1-7 As shown, the present application proposes a pipeline grooving device, including a connecting rod 1; multiple groups of connecting parts 2 slidingly arranged on the connecting rod 1; pressing tubes 3 with the same number as the connecting parts 2; the connecting part 2 includes a sleeve 21, a locking part 22 and a connecting seat 23; the sleeve 21 is adapted to the connecting rod 1; the locking part 22 is arranged on the sleeve 21 for fixing the position of the sleeve 21; the connecting seat 23 is arranged on the sleeve 21 for connecting the pressing tubes 3.

[0047] The sleeve 21 is a cylindrical component that matches the outer shape of the connecting rod 1. Specifically, it can be implemented by a metal tube with an inner diameter slightly larger than the outer diameter of the connecting rod 1. The inner wall of the sleeve 21 contacts the surface of the connecting rod 1 to form a sliding portion. The locking member 22 is a fastening mechanism used to limit the displacement of the sleeve 21. Specifically, it can be implemented by a structure in which a threaded rod is combined with an interference block 222. By screwing the threaded rod, the interference block 222 presses against the surface of the connecting rod 1 to generate friction. The connecting seat 23 is a mounting base for supporting the pressure tube 3. Specifically, it can be fixed to the outside of the sleeve 21 by welding or bolting. Its surface is provided with a positioning structure for fixing the pressure tube 3.

[0048] Specifically, when the sleeve 21 slides axially along the connecting rod 1, it can drive the connecting seat 23 and the pressure tube 3 to move to the target position. By screwing the threaded rod of the locking member 22, the resistance block 222 is pressed against the surface of the connecting rod 1, thereby fixing the position of the sleeve 21. The connecting seat 23 is rigidly connected to the pressure tube 3 to ensure that the pressure tube 3 does not undergo relative displacement during the concrete pouring process. The independent adjustment characteristics of multiple groups of connecting members 2 allow the spacing of the pressure tubes 3 to be flexibly arranged according to design requirements, and the mechanical fixing method of the locking member 22 can resist the impact force generated by the flow of concrete. When the spacing of the pressure grooves needs to be adjusted, it is only necessary to loosen the corresponding locking member 22 and move the sleeve 21 to the new position and then re-lock it. The positions of the remaining pressure tubes 3 will not be affected.

[0049] Compared with the prior art, the traditional grooving device adopts an integral fixed structure and cannot achieve local position adjustment. In contrast, this solution realizes multi-point positioning through independently adjustable connecting pieces 2 to meet different spacing requirements. In the prior art, the grooving device is prone to overall displacement during the vibration process. This solution fixes each pressure pipe 3 separately through a split locking structure, reducing the risk of overall displacement. In addition, when adjusting the spacing in the traditional device, the entire system needs to be reinstalled. In this solution, only specific sleeves 21 need to be moved to complete local adjustment.

[0050] Through the above technical solution, this application can accurately adjust the spacing of the pressure pipes 3 and ensure the firm fixation of the device during the pouring process, thus avoiding the problem of uneven spacing caused by the deviation of the grooving position. The frictional force generated by the locking piece 22 can effectively resist the impact of concrete flow, ensuring the positioning accuracy of the pressure pipes 3 throughout the pouring process. The modular design enables the device to adapt to the grooving layout requirements of different engineering scenarios, improving the grooving forming quality and construction efficiency.

[0051] This application further proposes that the connecting seat 23 includes two groups of fixedly arranged bearing pieces 231, and a pressing plate 232 movably arranged relative to the two groups of bearing pieces 231. A positioning bolt 2311 is arranged on the bearing piece 231, and an adjusting nut 2321 threadedly connected to the positioning bolt 2311 is rotatably arranged on the pressing plate 232. The two groups of pressing plates 232 are slidably arranged on the connecting seat 23.

[0052] Among them, the bearing piece 231 refers to a fixed structure for supporting the pressure pipe 3, which can be specifically realized by welding metal plates or bolt fixation, providing a rigid support surface when the pressure pipe 3 is installed. The positioning bolt 2311 refers to a rod-shaped component with an external thread, which can be specifically processed from a standard bolt and is used to cooperate with the adjusting nut 2321 to form an axial displacement drive. The adjusting nut 2321 refers to a rotating component with an internal thread, which can be specifically realized by a copper nut rotatably connected to the pressing plate 232, and generates an axial thrust through thread rotation to control the movement of the pressing plate 232. The slidably arranged pressing plate 232 refers to a clamping component that translates along a fixed track, which can be specifically realized by a slider and chute matching structure, and is used to maintain the linearity of the movement track during the adjustment process.

[0053] Specifically, the end of the pressure pipe 3 is placed between the two groups of bearing pieces 231. By rotating the adjusting nut 2321, the pressing plate 232 is driven to slide towards the bearing piece 231, and the pressing plate 232 and the bearing piece 231 form a clamping effect on the end of the pressure pipe 3. During the concrete pouring process, the continuous locking force generated by the threaded connection can effectively resist the displacement caused by vibration, and the symmetric sliding of the two groups of pressing plates 232 eliminates the skew caused by unilateral force. When the position of the pressure pipe 3 needs to be adjusted, rotating the adjusting nut 2321 in the reverse direction can release the clamping and achieve rapid position reset.

[0054] Compared with the prior art, traditional grooving devices mostly adopt fixed buckle or disposable strap fixing methods, which have defects such as insufficient clamping force and difficult position adjustment. This solution combines screw drive with a sliding pressure plate 232 to achieve stepless adjustment while ensuring sufficient clamping force, solving the technical problem of insecure fixation in a vibrating environment. Compared with the spring clamping structure, the screw locking method has higher anti-impact ability and position holding accuracy.

[0055] Through the above technical solution, this application can ensure that the pressure pipe 3 maintains an accurate installation position during concrete pouring, avoiding the deviation of the grooving spacing caused by mechanical vibration. The screw locking structure can provide continuous and stable clamping force to prevent the pressure pipe 3 from displacing under the flowing pressure of the concrete. The symmetric sliding pressure plate 232 design effectively balances the forces on both sides, ensuring that the axis of the pressure pipe 3 completely coincides with the preset trajectory, and finally forming a pipeline groove with precise dimensions and neat arrangement.

[0056] This application further proposes that the locking member 22 includes an adjusting screw rod 221, and a contact block 222 is rotatably provided at the end of the adjusting screw rod 221; the adjusting screw rod 221 penetrates through the inner wall of the sleeve 21 and is threadedly connected thereto.

[0057] Among them, the adjusting screw rod 221 refers to a rod-shaped component with an external thread structure, and specifically can be formed by processing a metal material into a spiral protrusion structure. Its outer diameter size matches the threaded hole on the inner wall of the sleeve 21. By rotating the adjusting screw rod 221, an axial displacement can be generated to push the contact block 222 to move linearly.

[0058] Among them, the contact block 222 refers to a pressure-bearing component that contacts the surface of the connecting rod 1, and specifically can be realized by a disk-shaped structure that can freely rotate around the axis. The rotational setting reduces sliding friction when the contact block 222 contacts the surface of the connecting rod 1, avoiding lateral displacement during the process of rotating the adjusting screw rod 221.

[0059] Specifically, when the adjusting screw rod 221 rotates, its external thread meshes with the threaded hole on the inner wall of the sleeve 21 to generate meshing drive, forcing the adjusting screw rod 221 to move radially inward along the sleeve 21. At this time, the contact block 222 at the end of the adjusting screw rod 221 is pressed against the surface of the connecting rod 1. As the rotation angle increases, the pressure of the contact block 222 on the surface of the connecting rod 1 gradually increases, and finally a stable frictional force is formed to fix the sleeve 21 at the preset position on the connecting rod 1. Due to the self-locking characteristic of the screw drive of the adjusting screw rod 221, the pressure can be kept constant after stopping rotation, preventing the sleeve 21 from shifting due to the vibration of the pouring operation.

[0060] Compared to existing technologies, traditional groove pressing devices often use bolts to directly tighten the connecting rod 1. This locking force is limited by the operator's manual tightening and is prone to loosening in vibrating environments. This solution controls the locking force through the axial pressure generated by the threaded engagement. This evenly distributes pressure across the contact surface between the abutment block 222 and the connecting rod 1, eliminating slippage caused by localized stress concentration and significantly improving the sleeve 21's ability to resist displacement under dynamic loads.

[0061] Through the above technical solution, the present application solves the problem of the groove pressing device shifting during concrete pouring due to the loose locking of sleeve 21 on connecting rod 1. The threaded transmission mechanism of the adjusting screw 221 realizes linear adjustment of the locking force, and the rotating structure of the resistance block 222 reduces the resistance of the locking operation. The two work together to ensure that sleeve 21 maintains stable positioning under the vibration environment of pouring, thereby avoiding uneven groove spacing and molding quality defects.

[0062] The present application further proposes that the pressure tube 3 is semi-cylindrical; a first connecting piece 31 is provided at one end of the pressure tube 3; a second connecting piece 32 is provided at the other end of the pressure tube 3; and positioning holes 33 corresponding to the positioning bolts 2311 are provided on both the first connecting piece 31 and the second connecting piece 32.

[0063] The semi-cylindrical compression tube 3 has a semicircular cross-section. Specifically, it can be formed by bending a metal sheet into an arc-shaped structure. The inner arc surface of the compression tube 3 conforms to the surface of the pipeline to be grooved, while the outer arc surface serves as a supporting surface. This shape design increases the contact area between the compression tube 3 and the pipeline, preventing local stress concentration during the grooving process that could cause pipeline deformation.

[0064] The first and second connecting pieces 31, 32 are plate-like structures welded or integrally formed at the ends of the compression tube 3. Specifically, they can be formed as extended, planar pieces at the ends of the compression tube 3 using a stamping process. The first and second connecting pieces 31, 32 extend perpendicular to the axis of the compression tube 3, forming a symmetrically distributed mounting base. The positioning holes 33 in the two connecting pieces are formed by laser cutting or drilling, with a diameter slightly larger than the diameter of the positioning bolts 2311 to ensure a clear fit.

[0065] Specifically, when the pressure pipe 3 needs to be installed on the connecting seat 23, the operator aligns the first connecting piece 31 and the second connecting piece 32 of the pressure pipe 3 with the bearing pieces 231 on both sides of the connecting seat 23 respectively, so that the positioning holes 33 are sleeved on the positioning bolts 2311. Then, by rotating the adjusting nut 2321, the pressing plate 232 is driven to slide along the connecting seat 23 until the pressing plate 232 is in close contact with the connecting piece. Since the two connecting pieces are fixed simultaneously, the displacement of the pressure pipe 3 in the axial direction is completely restricted. The clearance fit between the positioning holes 33 and the positioning bolts 2311 allows for fine adjustment of the pressure pipe 3 during installation, ensuring that the axis of the pressure pipe 3 is perpendicular to the connecting rod 1. When lateral impact forces are generated during concrete pouring, the double-point fixing structure formed by the two connecting pieces can effectively disperse the load and prevent the pressure pipe 3 from twisting or shifting.

[0066] Compared with the prior art, traditional grooving devices usually install the pressure pipe 3 by means of single-sided fixing or integral welding, which cannot achieve precise positioning and is difficult to adjust. For example, in some prior arts, the pressure pipe 3 is directly welded to the sleeve 21, resulting in the need for overall disassembly and assembly when replacing pipes of different diameters, with low construction efficiency. In this solution, through the double-connecting-piece structure in cooperation with the positioning bolts 2311, not only can the rapid disassembly and assembly of the pressure pipe 3 be achieved, but also the relative position between the axis of the pressure pipe 3 and the connecting rod 1 can be precisely controlled, avoiding grooving offset caused by installation errors.

[0067] Through the above technical solution, the present application solves the problem of grooving forming quality caused by insufficient positioning accuracy during the installation of the pressure pipe 3. The double-connecting-piece structure improves the stability of the pressure pipe 3 under dynamic loads and prevents displacement during the concrete vibration process. The matching design of the positioning holes 33 and the positioning bolts 2311 enables the adjustable installation of the pressure pipe 3, making the same grooving device adaptable to pressure pipes 3 of different sizes and enhancing the construction flexibility.

[0068] The present application further proposes to provide an installation space between the second connecting piece 32 and the end of the pressure pipe 3, and the length of this installation space is equal to the width of the connecting seat 23, so that the connecting seat 23 can be completely embedded in this space when two groups of pressure pipes 3 are butted.

[0069] Among them, the installation space refers to the clearance area formed between the second connecting piece 32 and the end of the pressure pipe 3, which can be specifically formed by adjusting the relative position between the end of the pressure pipe 3 and the second connecting piece 32. For example, a recessed structure is provided at the end of the pressure pipe 3 or the extension length of the second connecting piece 32 is extended. This space is used to accommodate the embedding of the connecting seat 23, and its length is equal to the width of the connecting seat 23, achieving lateral restraint during butting through mechanical limitation.

[0070] Among them, the width of the connecting seat 23 refers to the dimensional range of the connecting seat 23 along the axial direction of the pressure pipe 3, which can be specifically realized through standardized processing or an adjustable structure. The matching relationship between this dimension and the length of the installation space provides a positioning reference for the butt joint of the pressure pipe 3, ensuring the axial coincidence degree of the two groups of pressure pipes 3.

[0071] Specifically, when two groups of pressure pipes 3 need to be butted, the connecting seat 23 is completely restricted inside the installation space, and its width forms a rigid fit with the space length. At this time, the two side walls of the connecting seat 23 are respectively in contact with the second connecting piece 32 and the end of the pressure pipe 3, preventing the pressure pipe 3 from shifting laterally. Thus, the axes of adjacent pressure pipes 3 are automatically aligned, avoiding the misalignment problem caused by the exposure of the connecting seat 23 in the traditional butting method. During the concrete pouring process, the position stability of the pressure pipe 3 is improved, and the straightness and spacing uniformity of the pressure grooves are ensured.

[0072] Compared with the prior art, when the traditional pressure pipe 3 is butted, part of the connecting seat 23 is exposed outside, and it is easy to displace due to the flow of concrete or the vibration of the mold, resulting in the deviation of the axis of the pressure groove. In this solution, by completely embedding the connecting seat 23 into the installation space and using the width matching relationship to form physical limits, the interference of external factors on the butting position of the pressure pipe 3 is eliminated. This structural design can achieve precise butting without relying on complex positioning devices, simplifying the operation process and reducing construction errors.

[0073] This application further proposes that adjustment sliding grooves are provided on both sides of the connecting seat 23, and limiting sliding blocks extending into the adjustment sliding grooves are provided on the opposite sides of the two groups of pressing plates 232.

[0074] Among them, the adjustment sliding groove refers to a groove structure opened on both sides of the connecting seat 23, which can be specifically realized by using a rectangular groove or a T-shaped groove. Its function is to provide a linear guiding path for the movement of the pressing plate 232; the limiting sliding block refers to a convex structure fixed on the side surface of the pressing plate 232, which can be specifically realized by using a metal block or an integrally formed rib. Its function is to form a sliding fit with the adjustment sliding groove and limit the lateral displacement freedom of the pressing plate 232.

[0075] Specifically, when adjusting the position of the pressing plate 232, the limiting sliding block slides along the extending direction of the adjustment sliding groove, and the inner wall of the sliding groove forms a lateral constraint on the sliding block. When the pressing plate 232 is subjected to an external load, a reaction force is generated on the contact surface between the sliding groove and the sliding block, preventing the pressing plate 232 from laterally shifting or tilting, ensuring that the pressing plate 232 can only move parallel in the vertical direction. The two groups of pressing plates 232 always maintain a symmetric movement trajectory through the cooperation of their respective limiting sliding blocks and sliding grooves, thereby avoiding the deviation of the installation angle of the pressure pipe 3 caused by the shift.

[0076] Compared with the prior art, the adjustment mechanism of the traditional pressing plate 232 relies only on bolts for positioning and lacks a lateral limiting structure. During the tightening process, the pressing plate 232 is prone to positional deviation under the influence of external forces. Through the mechanical limit of the chute and the slider, the present application establishes a rigid guiding constraint, eliminates the redundant degrees of freedom during the adjustment of the pressing plate 232, and solves the technical defect that the positioning of the pressing tube 3 is inaccurate due to the offset of components in the traditional structure.

[0077] Through the above technical solution, the present application ensures that the pressing plate 232 maintains a vertical lifting state during movement, avoiding the alignment error between the pressing tube 3 and the connecting seat 23 caused by lateral deviation. The uniformity of the formed groove spacing is significantly improved, effectively ensuring the forming accuracy and visual quality of the concrete pressing groove.

[0078] The present application further proposes that anti-slip lines are provided at the bottom of the pressing plate 232 for contacting the first connecting piece 31.

[0079] Among them, the anti-slip lines refer to the concave-convex structure formed on the contact surface between the pressing plate 232 and the first connecting piece 31. Specifically, a cross pattern or a serrated continuous protrusion structure can be adopted to increase the friction coefficient of the contact surface and form a mechanical biting effect.

[0080] Among them, the first connecting piece 31 refers to the sheet-shaped connecting component provided at the end of the pressing tube 3. Specifically, a structure of stamping a metal sheet and opening positioning holes 33 can be adopted, and the positioning connection between the pressing tube 3 and the connecting seat 23 is realized through the cooperation of the positioning holes 33 and the positioning bolts 231].

[0081] Specifically, the anti-slip lines are provided in the area where the bottom of the pressing plate 232 contacts the first connecting piece 31. When the adjusting nut 2321 is tightened, the pressing plate 232 applies a downward pressure on the first connecting piece 31. At this time, the protruding parts of the anti-slip lines are embedded in the surface of the first connecting piece 31, forming a physical bite at the microscopic level. Under the vibration condition of concrete pouring, this biting structure can effectively resist lateral displacement, avoid the sliding cumulative error caused by vibration on the traditional flat contact surface, and ensure that the axis of the pressing tube 3 coincides precisely with the predetermined pressing groove trajectory.

[0082] Compared with the prior art, the bottom surface of the traditional pressing plate 232 is designed with a smooth plane and is prone to relative sliding with the connecting piece of the pressing tube 3 in a vibrating environment, resulting in the overall offset of the pressing tube 3. However, through the biting effect of the anti-slip lines, the anti-slip ability of the contact surface is significantly improved under the condition of the same locking force, and the position can be locked without additional locking components.

[0083] Through the above technical solution, the present application solves the problem of the offset of the groove forming caused by the easy sliding of the contact surface between the pressure pipe 3 and the connecting seat 23. The biting effect between the anti-slip lines and the first connecting piece 31 enables the pressure pipe 3 to remain stable during construction vibration, ensuring that the straightness accuracy and position consistency of the groove meet the requirements of concrete pouring and forming.

[0084] The present application further proposes that a limiting rotating ring is provided at the bottom of the adjusting nut 2321, and a receiving groove corresponding to the limiting rotating ring is also opened at the bottom of the pressing plate 232.

[0085] Among them, the limiting rotating ring refers to an annular convex structure fixed to the bottom of the adjusting nut 2321, which can be specifically realized by a metal ring integrally formed coaxially with the adjusting nut 2321. Its outer diameter size is slightly smaller than the inner diameter size of the receiving groove. During rotation, the axial displacement is restricted by the way of the annular convex being embedded in the groove. The receiving groove refers to an annular groove structure opened at the bottom of the pressing plate 232, which can be specifically formed by machining to form a recessed area matching the shape of the limiting rotating ring. The circumferential wrapping of the limiting rotating ring by the groove side wall realizes the dual functions of retaining the rotational freedom and restricting the axial displacement.

[0086] Specifically, when the adjusting nut 2321 is screwed onto the positioning bolt 2311, the limiting rotating ring is synchronously embedded in the receiving groove at the bottom of the pressing plate 232. At this time, the annular side surface of the limiting rotating ring and the inner wall of the receiving groove form a contact surface, so that the adjusting nut 2321 can only rotate around the axis of the positioning bolt 2311 during rotation and cannot move up and down along the axis direction. This structure eliminates the axial displacement caused by the thread fitting clearance through the mechanical limiting effect, so that the pressing plate 232 always maintains a vertical pressing state with the first connecting piece 31 during the locking process, avoiding the attenuation of the fixing force of the pressure pipe 3 caused by the axial movement of the nut.

[0087] Compared with the prior art, in the traditional locking mechanism of the pressing plate 232, the adjusting nut 2321 is directly threadedly connected to the positioning bolt 2311, and axial clearance is easily generated due to thread wear or assembly error during repeated rotation operations, resulting in the deviation of the pressing force direction of the pressing plate 232 on the connecting piece. This solution eliminates the possibility of axial displacement while retaining the rotation function of the nut through the physical limiting cooperation between the limiting rotating ring and the receiving groove, fundamentally solving the technical defect of the unstable fixation of the pressure pipe 3.

[0088] Through the above technical solution, the present application effectively prevents the problem of uneven force on the connecting piece of the pressure pipe 3 caused by the axial movement of the adjusting nut 2321 during the pressing operation, ensures that the pressing force applied by the pressing plate 232 on the connecting piece is always perpendicular to the contact surface, thereby improving the connection stability between the pressure pipe 3 and the connecting seat 23, and avoiding the position deviation of the pressure pipe 3 caused by vibration during the concrete pouring process.

[0089] The present application further proposes that a rotation groove 24 is provided on the connection base 23, and the rotation groove 24 is used to enable the pressure pipe 3 to rotate around the positioning bolt 2311 as the rotation center and along the rotation groove 24 until the pressure pipe 3 is parallel to the connecting rod 1 and in the storage state.

[0090] Among them, the rotation groove 24 refers to an arc-shaped guiding structure provided on the connection base 23, which can be specifically realized by a curved track formed by milling. Its radian matches the rotation trajectory of the pressure pipe 3. This structure provides mechanical constraints for the rotational movement of the pressure pipe 3, restricting its rotation within a preset angle range.

[0091] Among them, the positioning bolt 2311 refers to a fastening component that penetrates the bearing piece 231 and the connecting piece, which can be specifically realized by a threaded cylindrical metal piece. The fixed installation of this bolt on the bearing piece 231 forms a rotation fulcrum, which not only bears the radial load during the rotation of the pressure pipe 3 but also maintains the axial fixation of the connecting piece and the bearing piece 231.

[0092] Specifically, when the pressure pipe 3 needs to be stored, the pressure pipe 3 rotates around the positioning bolt 2311 as the axis. The arc-shaped inner wall of the rotation groove 24 is in clearance fit with the rotation trajectory of the pressure pipe 3, so that the rotation angle of the pressure pipe 3 is limited within the range of 0 - 90 degrees. During the rotation of the pressure pipe 3, the connecting piece moves along the curved path of the rotation groove 24 until the pressure pipe 3 is completely rotated to a position parallel to the axis of the connecting rod 1. At this time, multiple pressure pipes 3 form a linear arrangement in the length direction of the connecting rod 1, and the overall width of the device is reduced to the diameter size of a single pressure pipe 3. The limiting protrusion provided at the end of the rotation groove 24 contacts the connecting piece to prevent the pressure pipe 3 from continuing to rotate and thus maintain the stability of the storage state.

[0093] Compared with the prior art, the traditional pressure pipe 3 device needs to be disassembled or folded as a whole for storage in the non-use state, which is time-consuming and there is a risk of losing parts. Most of the existing storage methods adopt hinge structures. Although the folding function can be realized, the pressure pipes 3 are stacked after folding, resulting in an increase in the thickness of the device. This solution enables the pressure pipe 3 to rotate and be stored around a fixed axis through the cooperation of the rotation groove 24 and the positioning bolt 2311, effectively controlling the external dimensions after storage while maintaining the overall linear structure of the device.

[0094] Through the above technical solution, the present application enables the pressure pipe 3 to quickly rotate to the storage position parallel to the main rod in the non-operation state, significantly reducing the space occupied by the device. The mechanical limiting effect of the rotation groove 24 prevents the pressure pipe 3 from undergoing unexpected displacement during transportation or storage, maintaining the stability of the storage state. This storage method does not require disassembling parts, and the state conversion can be completed only by rotating a single pressure pipe 3 during the operation process, improving the convenience of using the device.

[0095] In the present application, multiple sets of pressing pipes 3 are misaligned and distributed on the connecting rod 1 when in the storage state. Preferably, the number of pressing pipes 3 and connecting members 2 on the connecting rod 1 is four sets, and additional connecting members 2 can be sleeved subsequently to supplement the corresponding pressing pipes 3 to cope with different construction scenarios.

[0096] Among them, the misaligned distribution means that multiple sets of pressing pipes 3 are arranged in a non-aligned manner in the length direction of the connecting rod 1. Specifically, the rotation angle of the pressing pipe 3 can be adjusted through the cooperation of the rotation groove 24 and the positioning bolt 2311, so that the pressing pipes 3 form a spatial staggered layout when in storage. This layout avoids the overall length superposition caused by the complete overlap of multiple sets of pressing pipes 3.

[0097] Among them, the storage state means that the pressing pipe 3 rotates around the positioning bolt 2311 to a folded position parallel to the connecting rod 1. Specifically, the rotation angle of the pressing pipe 3 can be restricted by the rotation groove 24 so that it finally remains parallel to the axis of the connecting rod 1. In this state, the pressing pipe 3 is closely attached to the connecting rod 1, reducing the occupation of external space.

[0098] Specifically, when the pressing pipe 3 rotates around the positioning bolt 2311 to the storage state, the rotation groove 24 guides the rotation axis of the pressing pipe 3 to be parallel to the connecting rod 1. Since the connecting seats 23 of multiple sets of pressing pipes 3 are slidably distributed along the connecting rod 1, by adjusting the positions of the sleeves 21 on the connecting rod 1, the rotation trajectories of adjacent pressing pipes 3 are staggered in the length direction of the connecting rod 1. At this time, the ends of the pressing pipes 3 are distributed in different sections of the connecting rod 1 in the storage state, forming a staggered arrangement structure. Thus, multiple sets of pressing pipes 3 will not be stacked along the same axis after folding, avoiding the increase in the overall length of the device caused by complete overlap, and at the same time reducing the mechanical interference caused by the position conflict between adjacent pressing pipes 3.

[0099] Compared with the prior art, the pressing pipes 3 of the traditional pipeline grooving device are usually aligned and folded along the axis of the connecting rod 1 when in storage, resulting in a multiple-fold increase in the overall length after multiple sets of pressing pipes 3 are stacked, occupying a large transportation or storage space. In addition, the stacked pressing pipes 3 need to be unfolded layer by layer during subsequent use, with low operation efficiency and easy structural jamming. Through the misaligned distribution design of this solution, the pressing pipes 3 only occupy the space within the length range of a single pressing pipe 3 when in storage, while maintaining independent unfolding paths for each pressing pipe 3 to avoid mutual interference.

[0100] Through the above technical solutions, the present application solves the problem of the device volume expansion caused by stacking when the pressing pipe 3 is in storage, reducing the storage and transportation costs; at the same time, the misaligned distribution enables each pressing pipe 3 to independently adjust its position during unfolding, avoiding friction loss caused by the contact of adjacent pressing pipes 3 in the storage state, and improving the reliability of the repeated use of the device.
