Description

Technical Field

[0001] This utility model relates to the field of pipeline installation technology, specifically to a water supply riser installation device. Background Technology

[0002] In water supply pipeline installation projects, riser installation is one of the core procedures, and its installation quality directly affects the stable operation of the subsequent water supply system. Current riser installation operations typically require first determining the installation position based on the height of the riser clamps, and then installing the prefabricated riser after the clamps are secured.

[0003] This operation requires at least two operators working together: one to support the riser from below and the other to connect and install it from above. The process is cumbersome, inefficient, and labor-intensive. Furthermore, existing hoisting equipment for riser installation generally suffers from complex structures and large sizes, making it inconvenient to handle and move. This is especially problematic in confined indoor spaces, where the equipment's suitability is extremely poor, further limiting the convenience and efficiency of the installation work and failing to meet the diverse needs of actual engineering construction. Utility Model Content

[0004] To address the problems and shortcomings of existing technologies, this utility model provides a water supply riser installation device. The aim is to solve the problems of time-consuming and labor-intensive manual installation of risers, as well as the inconvenience of relocation.

[0005] The technical solution of this utility model is as follows: To achieve the above objectives, this utility model provides a water supply riser installation device, including a winch assembly, a connecting main pipe, and a folding lifting bracket. The winch assembly includes a base and a winch connected to the base, with a traction rope wound around the winch to provide a controllable power source for lifting the pipe. The folding lifting bracket is detachably connected to the base via a vertically arranged connecting main pipe. This detachable connection design allows the winch assembly to be separated from the lifting assembly during movement, greatly facilitating the transportation, storage, and transfer of the equipment between different work sites.

[0006] The folding hoisting support includes a support pipe assembly and a connecting rod assembly. The connecting rod assembly, which can be folded upwards or unfolded downwards, includes a first connecting rod and a second connecting rod. The lower end of the second connecting rod is hinged to the lower part of the support pipe assembly, and the upper end is equipped with a second fixed pulley. One end of the first connecting rod is hinged to the second connecting rod, and the other end is hinged to the upper part of the support pipe assembly, with the end near the support pipe assembly connected to the first fixed pulley. By folding or unfolding the connecting rod assembly, the lateral extension position of the second fixed pulley relative to the main support pipe can be flexibly changed, facilitating unfolding during pipe hoisting and folding back when equipment needs to be moved or stored. The free end of the winch's traction rope sequentially passes over the first and second fixed pulleys and is connected to a hook, forming a clearly guided automatic lifting system.

[0007] Furthermore, the base is connected to the main connecting pipe via a connecting sleeve mounted on it. The connecting sleeve and the main connecting pipe are connected by a quick-connect structure, which enables rapid assembly and stable fixation of the vertical support components, improving equipment placement efficiency. The main connecting pipe and the main support pipe are preferably connected by threads, ensuring the connection strength and coaxiality of the core load-bearing structure.

[0008] More specifically, the quick-connect structure features symmetrically arranged U-shaped positioning grooves and bolt through holes on the sidewall of the connecting sleeve; a positioning protrusion that engages with the U-shaped positioning groove is located at the lower end of the connecting main tube, along with a mounting through hole coaxial with the bolt through hole. During installation, the positioning protrusion first engages with the U-shaped positioning groove, effectively limiting the circumferential rotation of the connecting main tube relative to the base, achieving rapid pre-positioning. Subsequently, the final axial connection is achieved by fastening bolts passing through the bolt through hole and the mounting through hole. This design breaks down the installation process into two simple steps: "insertion limiting" and "bolt tightening," significantly improving on-site assembly speed and reliability.

[0009] Furthermore, two sets of U-shaped positioning grooves are symmetrically arranged along the circumference of the connecting sleeve. The line connecting the center points of the two U-shaped positioning grooves forms a horizontal reference line, which intersects perpendicularly with the center line of the bolt through hole in the horizontal plane. This symmetrical and perpendicularly intersecting layout ensures that the connection node is subjected to more balanced forces when subjected to torques from different directions, resulting in stronger structural stability and effectively preventing loosening or deformation of the connection due to excessive force on one side.

[0010] The support pipe assembly specifically includes a main support pipe and a rotating sleeve. The lower part of the main support pipe is connected to the connecting main pipe, and the upper part is fitted with the rotating sleeve. The rotating sleeve and the main support pipe are rotatably connected via bearings, thus possessing rotational freedom about the axis of the main support pipe. The first connecting rod and the second connecting rod are hinged to the lower and upper ends of the rotating sleeve, respectively. This rotational freedom allows the entire folding hoisting bracket and hook to rotate 360° in the horizontal plane, enabling the operator to easily adjust the hoisting direction without moving the bulky base, greatly enhancing the equipment's adaptability to complex indoor layouts.

[0011] The rotating sleeve and the main support pipe are preferably connected by a fixed seat and a thrust bearing. The fixed seat is used to connect the bearing race and provide structural support, while the thrust bearing can effectively withstand the axial load generated during hoisting, ensuring smooth and stable rotation and long-term reliability.

[0012] The hook lifts the riser pipe using a riser clamp. The riser clamp includes a connecting seat, a clamping mechanism, and a drive motor. The connecting seat has a lifting ring at the top for being lifted by the hook.

[0013] The clamping mechanism of the riser clamp preferably adopts a symmetrical jaw structure. The drive motor and the clamping mechanism are connected by a worm gear or rack and pinion transmission method, which can accurately drive the jaw to achieve synchronous opening and closing action, ensuring that the clamping force is evenly applied to both sides of the pipe and avoiding the pipe from being twisted or slipping.

[0014] To enhance safety, the winch is equipped with a traction rope retraction and extension limit device. This device can mechanically or electrically limit the maximum retraction and extension stroke of the traction rope, preventing the hook from colliding with the support due to excessive rising or excessive descending, which could cause the rope to loosen and effectively prevent equipment damage or safety accidents caused by this.

[0015] The beneficial effects of this utility model are: This utility model provides a water supply riser installation device that, through modular design and a quick-connect structure, enables convenient disassembly, assembly, and transportation of the winch assembly, connecting main pipe, and foldable hoisting bracket, significantly improving the equipment's adaptability in confined construction spaces. Its 360° horizontally rotating and adjustable hoisting bracket, combined with a guide lifting system composed of fixed pulleys, allows a single person to precisely control the raising, lowering, and horizontal adjustment of the riser from the ground. Dedicated riser clamps ensure stable pipe clamping and even force distribution. This equipment changes the traditional operation mode that relies on multiple people working together to lift the pipe, reducing labor intensity and labor costs while improving installation efficiency.

[0017] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0018] Example 1 This utility model provides a water supply riser installation device, see [link]. Figure 1The system includes a winch assembly 1, a connecting main pipe 2, and a folding lifting bracket 3. The winch assembly 1 includes a base 11 and a winch 12 connected to the base 11. A traction rope is wound around the winch 12, providing a controllable power source for pipe lifting. The folding lifting bracket 3 is detachably connected to the base 11 via the vertically positioned connecting main pipe 2. This detachable connection design allows the winch assembly 1 to be separated from the lifting assembly during movement, greatly facilitating the transportation, storage, and transfer of the equipment between different work sites.

[0019] The folding hoisting bracket 3 includes a support pipe assembly and a connecting rod assembly. The connecting rod assembly, capable of being folded upwards or unfolded downwards, includes a first connecting rod 34 and a second connecting rod 36. The lower end of the second connecting rod 36 is hinged to the lower part of the support pipe assembly, and the upper end is equipped with a second fixed pulley 35. One end of the first connecting rod 34 is hinged to the second connecting rod 36, and the other end is hinged to the upper part of the support pipe assembly, with the end near the support pipe assembly connected to the first fixed pulley 33. By folding or unfolding the connecting rod assembly, the lateral extension position of the second fixed pulley 35 relative to the main support pipe 31 can be flexibly changed, facilitating unfolding during pipe hoisting and folding it back when equipment needs to be moved or stored. The free end of the winch 12's traction rope sequentially passes around the first fixed pulley 33 and the second fixed pulley 35 and is connected to a hook 4, forming a clearly guided automatic lifting system.

[0020] Furthermore, the base 11 is connected to the connecting main pipe 2 via a connecting sleeve 111 mounted thereon. The connecting sleeve 111 and the connecting main pipe 2 are connected by a quick-connect structure, which enables rapid assembly and stable fixing of the vertical support components, improving equipment positioning efficiency. Preferably, the connecting main pipe 2 and the supporting main pipe 31 are connected by threads to ensure the connection strength and coaxiality of the core load-bearing structure.

[0021] For more details, see Figure 2 The quick-connect structure features symmetrically arranged U-shaped positioning grooves and bolt through holes on the side wall of the connecting sleeve 111; a positioning block 21, which engages with the U-shaped positioning groove, and a connecting hole 22, coaxially corresponding to the bolt through hole, are located at the lower end of the connecting main pipe 2. During installation, the positioning block 21 is first fitted into the U-shaped positioning groove. This step effectively restricts the circumferential rotation of the connecting main pipe 2 relative to the base 11, achieving rapid pre-positioning. Subsequently, the final axial connection is achieved by fastening bolts passing through the bolt through hole and the connecting hole 22. This design breaks down the installation into two simple steps: "insertion limiting" and "bolt tightening," significantly improving on-site assembly speed and reliability.

[0022] Furthermore, two sets of U-shaped positioning grooves are symmetrically arranged along the circumference of the connecting sleeve 111. The line connecting the center points of the two U-shaped positioning grooves forms a horizontal reference line, which intersects perpendicularly with the center line of the bolt through hole in the horizontal plane. This symmetrical and perpendicularly intersecting layout makes the connection node more evenly stressed when subjected to torques from different directions, resulting in stronger structural stability and effectively preventing loosening or deformation of the connection due to excessive force on one side.

[0023] See Figure 1 The support pipe assembly specifically includes a main support pipe 31 and a rotating sleeve 32. The lower part of the main support pipe 31 is connected to the connecting main pipe 2, and the upper part is fitted with the rotating sleeve 32. The rotating sleeve 32 and the main support pipe 31 are rotatably connected by bearings, thus possessing a degree of freedom of rotation about the axis of the main support pipe 31. The first connecting rod 34 and the second connecting rod 36 are hinged to the lower end and the upper end of the rotating sleeve 32, respectively. This degree of rotational freedom allows the entire folding hoisting bracket 3 and the hook 4 to rotate 360° in the horizontal plane. The operator can easily adjust the hoisting direction without moving the bulky base 11, greatly enhancing the adaptability of the equipment to complex indoor layouts.

[0024] The rotating sleeve 32 and the support main tube 31 are preferably rotatably connected by a fixed seat and a thrust bearing. The fixed seat is used to connect the outer ring of the bearing and provide structural support, while the thrust bearing can effectively withstand the axial load generated during hoisting, ensuring smooth and reliable rotation.

[0025] To enhance safety, the winch 12 is equipped with a traction rope retraction and extension limit device. This device can mechanically or electrically limit the maximum retraction and extension stroke of the traction rope, preventing the hook 4 from colliding with the support due to excessive rising or excessive descending, thus avoiding rope slack and effectively preventing equipment damage or safety accidents caused by it.

[0026] Example 2 A water supply riser installation device includes a winch assembly 1, a connecting main pipe 2, and a folding hoisting bracket 3. The difference from Embodiment 1 is that: The lifting hook 4 lifts the riser pipe via the riser clamp 5. (See also...) Figure 3 The riser clamp 5 includes a connecting seat, a clamping mechanism, and a drive motor. The top of the connecting seat has a lifting ring for being lifted by the hook 4. The rear of the connecting seat may also have a sliding groove for engaging with a vertically positioned guide rail, allowing the riser clamp 5 to move vertically. This design assists in guidance during hoisting, further ensuring the verticality and stability of the riser during placement and reducing the amount of manual straightening work.

[0027] The clamping mechanism of the riser clamp 5 preferably adopts a symmetrical jaw structure. The drive motor and the clamping mechanism are connected by a worm gear or rack and pinion transmission method, which can accurately drive the jaw to achieve synchronous opening and closing action, ensuring that the clamping force is evenly applied to both sides of the pipe and preventing the pipe from being twisted or slipped.
