[0002] In municipal road construction, the installation of stormwater and sewage pipes is a crucial step. With the acceleration of urbanization, the scale of stormwater and sewage pipe laying in municipal roads is constantly expanding, and the requirements for construction efficiency and quality are also increasing.

[0003] However, existing auxiliary equipment for hoisting and transporting municipal road storm and sewage pipes has some obvious shortcomings: it often lacks flexible adjustment capabilities when dealing with different types of sewage pipes, making it difficult to adapt to sewage pipes of various lengths and diameters, resulting in poor equipment versatility; many devices do not clamp and fix sewage pipes securely and reliably during hoisting, which can easily lead to lateral slippage of the sewage pipes, affecting construction progress, posing safety hazards, and even damaging the sewage pipes; moreover, the structural design of some equipment is not reasonable, and the operation is relatively complex and cumbersome, making it impossible to efficiently complete hoisting operations and failing to meet the growing needs of municipal road storm and sewage pipe construction.

[0004] These shortcomings severely restrict the smooth progress of municipal road stormwater and sewage pipe construction and the effective guarantee of construction quality. Utility Model Content

[0010] Furthermore, each set of mounting brackets includes a connecting frame connected to the adjusting mechanism and a longitudinal mounting beam fixed to the connecting frame; the longitudinal mounting beam is arranged perpendicularly to the hoisting crossbeam, and the clamp is connected to the longitudinal mounting beam on the corresponding side.

[0011] Furthermore, the longitudinal mounting beam is hollow; the clamp includes a clamping drive component disposed in the hollow cavity of the longitudinal mounting beam, and a jaw connected to the clamping drive component. The jaw is used to open outward or retract inward under the action of the clamping drive component to clamp or release the rainwater and sewage pipes.

[0012] Furthermore, the gripper includes two clamping arms arranged at relatively intervals; the clamping drive includes a double-ended lead screw rotatably supported in the hollow cavity of the longitudinal mounting beam, a geared motor for driving the double-ended lead screw to rotate, and two second lead screw sleeves threaded onto the outer circles of both ends of the double-ended lead screw; at least one end of the double-ended lead screw extends axially out of the longitudinal mounting beam, the geared motor is fixed to the outer end of the longitudinal mounting beam, and is fixed to the end of the double-ended lead screw of the telescopic longitudinal mounting beam; the two clamping arms are respectively fixedly connected to the two second lead screw sleeves.

[0015] Furthermore, the inner wall surface of the elastic wear-resistant layer or the cladding is provided with outwardly protruding anti-slip stripes to increase contact friction.

[0016] Furthermore, the clamping arm also includes multiple clamping tabs arranged at intervals along the extension direction of the clamping plate; one end of each clamping tab is fixed to the outer end of the clamping plate, and the other end of each clamping tab extends toward the center of the jaws, so that when the two sets of jaws are clamped relative to each other on the outer wall surfaces of the two ends of the rainwater and sewage pipe, the multiple clamping tabs on the two sets of jaws respectively abut against the outer end faces of the two ends of the rainwater and sewage pipe, thereby clamping and limiting the rainwater and sewage pipe along the axial direction.

[0033] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered below.

[0034] Reference Figure 1 and Figure 2 A preferred embodiment of this utility model provides an auxiliary device for the construction and hoisting of rainwater and sewage pipes, comprising: a hoisting beam 1 for connection to hoisting equipment, an adjusting mechanism 2 connected within the hoisting beam 1, two sets of mounting brackets 3 arranged opposite each other at the transverse ends of the hoisting beam 1, and two sets of clamps respectively connected to the two sets of mounting brackets 3. The adjusting mechanism 2 is connected to the two sets of mounting brackets 3 respectively to drive the two sets of mounting brackets 3 to move closer together or further apart. The two sets of clamps are used to clamp the two ends of the rainwater and sewage pipes 4 to be hoisted.

[0035] This utility model discloses an auxiliary equipment for the construction and hoisting of rainwater and sewage pipes, including a distance adjustment mechanism 2 and two sets of mounting brackets 3 connected to the distance adjustment mechanism 2. Each set of mounting brackets 3 is equipped with a set of clamps. The distance adjustment mechanism 2 can adjust the two sets of mounting brackets 3 to be relatively close or far apart, and correspondingly adjust the two sets of clamps to be close or far apart, thereby flexibly adjusting the distance between the two sets of clamps. This allows the device to adapt to the hoisting of rainwater and sewage pipes 4 of different lengths, thus greatly expanding the applicability of the equipment. Secondly, the two sets of clamps can clamp the two ends of the rainwater and sewage pipes 4 respectively, which not only allows for precise clamping according to different pipe diameters of rainwater and sewage pipes 4, further enhancing the adaptability of the equipment to different models of rainwater and sewage pipes 4, but also effectively prevents the rainwater and sewage pipes 4 from sliding laterally along the axial direction during hoisting, thus significantly improving the stability and safety of hoisting. Therefore, in summary, this new equipment performs excellently in the hoisting operation of storm and sewage pipes. It can easily handle various types of storm and sewage pipes, ensuring the efficiency and versatility of construction hoisting. It can also effectively ensure the safety and reliability of storm and sewage pipes during hoisting, preventing dangerous situations such as lateral slippage, and effectively reducing construction risks and potential losses. This compact and fully functional equipment provides strong support and guarantee for the construction and hoisting of storm and sewage pipes in municipal roads, helps improve the quality and progress of engineering construction, and has important practical application value and positive significance, bringing great convenience and efficiency to municipal engineering construction.

[0036] Optionally, such as Figure 2 As shown, the lifting beam frame 1 includes a longitudinally arranged lifting crossbeam 11 and two sets of lifting rings 12 fixedly connected to both ends of the lifting crossbeam 11. The lifting crossbeam 11 is hollow, and the adjusting mechanism 2 is located inside the hollow cavity of the lifting crossbeam 11. In this optional scheme, the lifting crossbeam 11 is arranged along the length of the rainwater and sewage pipe 4, and the two sets of mounting brackets 3 are arranged at both ends of the lifting crossbeam 11, so that it can be lifted along the axial direction of the rainwater and sewage pipe 4, increasing the safety and stability of the lifting. The hollow design of the lifting crossbeam 11 and the adjusting mechanism 2 located inside the lifting crossbeam 11 protect the adjusting mechanism 2 and prevent dust at the construction site from affecting the working accuracy of the adjusting mechanism 2. The lifting rings 12 are designed to facilitate detachable connection with the lifting equipment.

[0037] Optionally, such as Figure 2 and Figure 3As shown, the adjusting mechanism 2 includes a dual-shaft geared motor 21 fixed in the hollow cavity of the lifting beam 11, two drive screws 22 fixedly connected to the output shafts on both sides of the dual-shaft geared motor 21, and two first screw sleeves 23 threadedly connected to the outer circumference of the two drive screws 22 respectively. The two ends of the two drive screws 22 are also rotatably supported within the lifting beam 11. Two sets of mounting brackets 3 are fixedly connected to the two first screw sleeves 23 respectively. During operation, the dual-shaft geared motor 21 starts, driving the two drive screws 22 to rotate synchronously, which in turn drives the two first screw sleeves 23 to move synchronously. Since the two drive screws 22 rotate in opposite directions, the two first screw sleeves 23 move towards each other or away from each other, thereby driving the two sets of mounting brackets 3 to move towards each other or away from each other accordingly. Ultimately, this causes the two sets of clamps to move towards each other or away from each other, adapting to the clamping and lifting requirements of rainwater and sewage pipes 4 of different lengths.

[0038] Optionally, such as Figure 2 As shown, each set of mounting brackets 3 includes a connecting frame 31 connected to the adjusting mechanism 2, and a longitudinal mounting beam 32 fixed to the connecting frame 31. The longitudinal mounting beam 32 is arranged perpendicularly to the lifting beam 11, and the clamps are connected to the longitudinal mounting beam 32 on the corresponding side. In each set of mounting brackets 3, the longitudinal mounting beam 32 and the lifting beam 11 are arranged perpendicularly, and the two are also fixed by the intermediate connecting frame 31. This structural arrangement can make the force transmission of the entire mounting bracket 3 uniform, thereby improving the stability of the rainwater and sewage pipe 4 during hoisting and preventing deflection during hoisting.

[0039] Furthermore, such as Figure 2 As shown, the longitudinal mounting beam 32 is hollow. The clamp includes a clamping drive 5 disposed within the hollow cavity of the longitudinal mounting beam 32, and grippers 6 connected to the clamping drive 5. The grippers 6 are used to open outward or retract inward under the action of the clamping drive 5 to clamp or release the rainwater and sewage pipes 4. In this optional embodiment, the longitudinal mounting beam 32 is hollow to accommodate the clamping drive 5, preventing the clamping drive 5 from being affected by the external construction environment and improving the working accuracy of the clamping drive 5.

[0040] In this optional solution, such as Figure 2 and Figure 5As shown, the gripper 6 includes two clamping arms 61 spaced apart from each other. The clamping drive component 5 includes a double-ended lead screw 51 rotatably supported in the hollow cavity of the longitudinal mounting beam 32, a reduction motor 52 for driving the double-ended lead screw 51 to rotate, and two second lead screw sleeves 53 threaded onto the outer circumferences at both ends of the double-ended lead screw 51. At least one end of the double-ended lead screw 51 extends axially out of the longitudinal mounting beam 32. The reduction motor 52 is fixed to the outer end of the longitudinal mounting beam 32 and to the end of the double-ended lead screw 51 of the telescopic longitudinal mounting beam 32. The two clamping arms 61 are respectively fixedly connected to the two second lead screw sleeves 53. During operation, the geared motor 52 starts and drives the double-ended lead screw 51 to rotate. When the double-ended lead screw 51 rotates, it drives the two second lead screw sleeves 53 to move synchronously. Since the external threads machined on the outer circles at both ends of the double-ended lead screw 51 rotate in opposite directions, the double-ended lead screw 51 will drive the two second lead screw sleeves 53 to move towards each other or away from each other synchronously. This will cause the two clamping arms 61 to move relative to each other to clamp the rainwater and sewage pipe 4 or to move away from each other to release the clamped rainwater and sewage pipe 4, thereby adapting to the clamping of rainwater and sewage pipes 4 with different diameters.

[0041] In specific embodiments of this optional solution, such as Figure 4 As shown, each clamping arm 61 includes a connecting rod 611 fixed to the corresponding side second lead screw sleeve 53, and a clamping plate 612 fixed to the bottom end of the connecting rod 611. The clamping plate 612 is an arc-shaped plate to fit and clamp against the outer wall surface of the rainwater and sewage pipe 4. In a specific embodiment of this optional solution, the arc-shaped arrangement of the clamping plate 612 is used to increase the contact and clamping area with the pipe fitting to be clamped, thereby improving the stability and safety of clamping.

[0042] Preferably, such as Figure 4 As shown, the inner wall surface of the clamping plate 612 is provided with an elastic wear-resistant layer 613, or the clamping arm 61 is formed of a plastic material. In this preferred embodiment, the elastic wear-resistant layer 613 or the plastic material has good elasticity and wear resistance to increase the friction between the clamping claw 6 and the contact surface of the rainwater and sewage pipe 4, thereby improving the clamping stability of the clamping claw 6.

[0043] Preferably, such as Figure 4 As shown, the inner wall surface of the elastic wear-resistant layer 613 or the clamping plate 612 is provided with outwardly protruding anti-slip stripes 614 to increase the contact friction force, thereby further improving the stability of the gripper 6.

[0044] Preferably, such as Figure 4As shown, the clamping arm 61 also includes a plurality of clamping tabs 615 arranged at intervals along the extension direction of the clamping plate 612. One end of each clamping tab 615 is fixed to the outer end of the clamping plate 612, and the other end of each clamping tab 615 extends toward the center of the jaw 6. When the two sets of jaws 6 are clamped relative to each other on the outer wall surfaces at both ends of the rainwater and sewage pipe 4, the plurality of clamping tabs 615 on the two sets of jaws 6 respectively abut against the outer end faces of both ends of the rainwater and sewage pipe 4, thereby clamping and limiting the rainwater and sewage pipe 4 axially. When the two sets of jaws 6 are clamped on the outer wall surfaces at both ends of the rainwater and sewage pipe 4, the plurality of clamping tabs 615 on the two clamping arms 61 of each set of jaws 6 abut against the end faces of the corresponding ends of the rainwater and sewage pipe 4, thereby effectively preventing the rainwater and sewage pipe 4 from sliding axially during hoisting.

[0045] In this optional design, the arc-shaped clamping plate 612, the elastic wear-resistant rubber layer 613, the anti-slip stripes 614, and the end pressing protrusions 615 on the clamping arm 61 not only allow the clamping claw 6 to fit tightly against the surface of the rainwater and sewage pipe 4, increasing friction, but also effectively prevent the rainwater and sewage pipe 4 from sliding laterally during hoisting, thereby significantly improving the stability of hoisting. Furthermore, the clamping drive component 5 can drive the front and rear clamping arms 61 to move relative to each other and in opposite directions, thereby enabling precise clamping of rainwater and sewage pipes 4 with different diameters, further enhancing the equipment's adaptability to different types of rainwater and sewage pipes.

[0046] In summary, this new equipment not only easily handles various models of storm and sewage pipes during hoisting operations, ensuring high efficiency and versatility in construction and transportation, but also ensures the safety and reliability of the pipes during hoisting through a series of stabilization measures, preventing dangerous situations such as lateral slippage and effectively reducing construction risks and potential losses. This compact and fully functional equipment provides strong support and guarantee for the construction and hoisting of storm and sewage pipes in municipal roads, helping to improve the quality and progress of engineering construction. It has significant practical application value and positive significance, bringing great convenience and improved benefits to municipal engineering construction.

[0047] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
