[0002] During the installation and construction of large-diameter valves, it is necessary to coaxially install the large-diameter valves on large-diameter pipes (diameter greater than 300mm). The traditional construction method is: the construction personnel use a manual hoist to lift the large-diameter valve to the large-diameter pipe, and then manually drag the large-diameter valve to align with the flange of the large-diameter pipe, and then tighten the bolts to connect and fix the large-diameter valve and the flange of the large-diameter pipe.

[0003] For large-diameter pipelines installed at high places, the traditional large-diameter valve installation requires high-altitude work, which is difficult to drag and rotate, resulting in poor alignment accuracy between the axis of the large-diameter valve and the axis of the large-diameter pipeline, and the large-diameter valve bolt hole and the flange bolt hole of the large-diameter pipeline cannot be accurately aligned. The installation process is time-consuming and laborious, and there are certain safety hazards. Therefore, it is necessary to provide a large-diameter valve installation auxiliary bracket that can solve the problems of high-altitude dragging and rotation difficulties and poor alignment accuracy of large-diameter valves in the prior art.

[0008] The end of the pipeline fixing rope passes through the lifting hole of the lifting ring and is locked by a clamping ring, so that the pipeline fixing rope is fixedly connected to the lifting ring.

[0009] The pipeline fixing rope is located between the valve moving vehicle and the pipeline supporting seat, and the pipeline fixing rope and the pipeline supporting seat have opposite pressing directions on the large-diameter pipeline.

[0010] The valve moving vehicle comprises support rails, pulleys and a vehicle frame; the vehicle frame is arranged in a base frame, a plurality of pulleys are rotatably mounted on both sides of the vehicle frame, and wheel grooves matching the pulleys are formed on the inner walls on both sides of the base frame, so that the vehicle frame can be movably embedded in the base frame; a pair of support rails are rotatably arranged on the vehicle frame through clips, the pair of support rails are symmetrically arranged about the central axis in the length direction of the mounting base, and the large-diameter valve is placed on the pair of support rails.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] Please see attached Figure 1 and attached Figure 2 A large-diameter valve installation auxiliary bracket comprises a mounting base 1, a valve moving vehicle 2 and a pipe support seat 4; the pipe support seat 4 is mounted at one end of the mounting base 1, and the mounting base 1 is detachably mounted at the bottom of a large-diameter pipe 5, so that the pipe support seat 4 abuts against the bottom of the outer wall of the large-diameter pipe 5; the valve moving vehicle 2 is movably embedded in the mounting base 1, and the moving direction of the valve moving vehicle 2 is consistent with the axial direction of the large-diameter pipe 5, and the large-diameter valve 6 is rotatably placed on the valve moving vehicle 2, so that the large-diameter valve 6 is coaxially docked with the large-diameter pipe 5 through the valve moving vehicle 2.

[0026] The mounting base 1 is installed below the large-diameter pipe 5 and supported on the outer wall of the large-diameter pipe 5 by the pipe support seat 4 so that the longitudinal center axis of the mounting base 1 is parallel to the axial direction of the large-diameter pipe 5 .

[0027] The valve moving vehicle 2 is used to support the large-diameter valve 6, and the axial direction of the large-diameter valve 6 is located on the longitudinal center axis of the mounting base 1, so that the axial directions of the large-diameter valve 6 and the large-diameter pipeline 5 are located on the same straight line. When the valve moving vehicle 2 is moved, the large-diameter valve 6 can be brought close to the large-diameter pipeline 5 and ensured to be precisely aligned with the large-diameter pipeline 5 coaxially.

[0028] At the same time, the large-diameter valve 6 can rotate on the valve moving vehicle 2 with its axial direction as the axis, so that the screw hole positions on the large-diameter valve 6 are aligned with the flange screw hole positions on the large-diameter pipeline 5, making it easy to install the large-diameter valve 6 on the flange of the large-diameter pipeline 5 by bolts and nuts.

[0029] Please see attached Figure 3 The mounting base 1 includes a two-way self-locking manual winch 3, a pipe fixing rope 15, a base frame 16 and a lifting ring 17; the base frame 16 is a ring frame structure, the two-way self-locking manual winch 3 and the lifting ring 17 are respectively arranged on two opposite sides of the base frame 16, and the pipe fixing rope 15 is connected between the two-way self-locking manual winch 3 and the lifting ring 17 and pressed against the top of the large-diameter pipe 5.

[0030] Preferably, the two-way self-locking manual winch 3 may include a base, a winch and a hand crank, wherein the base is fixed to one side of the base frame 16, the winch is rotatably mounted on the base, and one end of the hand crank is coaxially connected to the winch. The winch and the hand crank of the two-way self-locking manual winch 3 may adopt the self-locking hand crank winch of the prior art, such as a winch and a hand crank connected by a worm gear transmission, and the self-locking function of the worm gear is utilized to ensure that the winch rotates only under the drive of the hand crank, and can be automatically locked when the hand crank is released, thereby ensuring that the pipeline fixing rope 15 is tightened and does not fall out.

[0031] When the other end of the hand crank is manually rotated, the winch can be driven to rotate. When the winch rotates in one direction, the pipe fixing rope 15 is wound on the winch, and the pipe fixing rope 15 is tightened to press the pipe fixing rope 15 against the large-diameter pipe 5, and different downward pressures can be applied to the large-diameter pipe 5 to adjust the parallelism between the longitudinal axis of the base frame 16 and the axial direction of the large-diameter pipe 5. When the winch rotates in the other direction, the wound pipe fixing rope 15 is released, and the pipe fixing rope 15 is loosened, which facilitates the disassembly and assembly of the base frame 16 on the large-diameter pipe 5, and can also be applied to large-diameter pipes 5 with different diameters.

[0032] Preferably, the pipeline fixing rope 15 can be made of a steel wire rope, and the outer part of the steel wire rope is sleeved with a rubber sleeve, which can prevent the large-diameter pipeline 5 from being worn and prevent the pipeline fixing rope 15 from slipping on the large-diameter pipeline 5. The lifting ring 17 can be made of a perforated steel plate and welded to the other side of the base frame 16, so as to facilitate the installation of the steel wire rope of the pipeline fixing rope 15.

[0033] Please see attached Figure 3 The end of the pipeline fixing rope 15 passes through the lifting hole of the lifting ring 17 and is locked by the clamping ring 14, so that the pipeline fixing rope 15 is fixedly connected to the lifting ring 17.

[0034] The clamp ring 14 is used to lock one end of the pipeline fixing rope 15 to the main body of the pipeline fixing rope 15 after passing it through the lifting hole of the lifting ring 17. Preferably, the clamp ring 14 can be a U-shaped clamp, which is locked by bolts and nuts, and is easy to disassemble and assemble, and the locking is reliable.

[0035] Please see attached Figure 1 and attached Figure 2 The pipeline fixing rope 15 is located between the valve moving vehicle 2 and the pipeline supporting seat 4, and the pipeline fixing rope 15 and the pipeline supporting seat 4 press against the large-diameter pipeline 5 in opposite directions.

[0036] The pipe fixing rope 15 and the pipe supporting seat 4 are staggered in the axial direction of the large-diameter pipe 5, so that the downward pressure of the pipe fixing rope 15 on the large-diameter pipe 5 and the supporting force of the pipe supporting seat 4 on the large-diameter pipe 5 can stably install the base frame 16 under the large-diameter pipe 5, and by adjusting the downward pressure and the supporting force, the longitudinal center axis of the base frame 16 is adjusted to be parallel to the axial direction of the large-diameter pipe 5.

[0037] Please see attached Figure 1 , Attachment Figure 2 and attached Figure 4 The valve moving vehicle 2 includes a support rail 7, a pulley 8 and a vehicle frame 18; the vehicle frame 18 is arranged in a base frame 16, and a plurality of pulleys 8 are rotatably mounted on both sides of the vehicle frame 18 through axles via clips 9, and wheel grooves matching the pulleys 8 are formed on the inner walls on both sides of the base frame 16, so that the vehicle frame 18 can be movably embedded in the base frame 16; a pair of support rails 7 are rotatably arranged on the vehicle frame 18 through clips 9, and the pair of support rails 7 are symmetrically arranged about the central axis in the length direction of the mounting base 1, and the large-diameter valve 6 is placed on the pair of support rails 7.

[0038] Preferably, the base frame 16 can be a rectangular frame made of channel steel, and the body frame 18 can be a rectangular or square frame made of square steel that is smaller than the base frame 16 , so that the body frame 18 can move flexibly in the base frame 16 through the pulley 8 .

[0039] The channel steel groove of the base frame 16 is used as a wheel groove for the installation and sliding of the pulley 8. A pulley 8 is set at each of the four corners of the vehicle body frame 18 to ensure that the vehicle body frame 18 performs stable linear motion in the base frame 16 along the length direction of the base frame 16.

[0040] Preferably, the pair of support rails 7 can be made of round steel, and the two ends of the round steel are limited on the vehicle frame 18 by the inverted U-shaped clamp 9, and the round steel can rotate with its axis as the axis in the space between the clamp 9 and the vehicle frame 18. The large-diameter valve 6 is placed on the pair of support rails 7, and friction is formed between the large-diameter valve 6 and the support rails 7. When the large-diameter valve 6 is rotated to align with the screw hole position, the friction can be used to drive the pair of support rails 7 to rotate synchronously, thereby ensuring that the rotation of the large-diameter valve 6 is labor-saving and smooth.

[0041] Please see attached Figure 1 and attached Figure 2 The pipe support seat 4 comprises a pair of support units, and the pair of support units are symmetrically arranged about the longitudinal center axis of the base frame 16.

[0042] A pair of support units are symmetrically arranged, which can not only provide stable and balanced support force for the large-diameter pipe 5, but also facilitate the adjustment of the longitudinal center axis of the base frame 16 and the axial direction of the large-diameter pipe 5 to a parallel state, thereby facilitating the precise installation of the large-diameter valve 6.

[0043] Please see attached Figure 5 Each group of the support units includes a supporting nut 10, a screw rod 11 and a supporting plate 13; a through hole 19 is formed on the base frame 16, and the supporting nut 10 is rotatably mounted on the base frame 16 through a rotating bearing and is coaxially aligned with the through hole 19; the screw rod 11 passes through the through hole 19 and is screwed to match the supporting nut 10, and the supporting plate 13 is obliquely arranged on the screw rod 11, so that the supporting plates 13 of a pair of support units are symmetrically abutted against the two sides of the large-diameter pipe 5.

[0044] The supporting nut 10 can rotate bidirectionally on the base frame 16 by rotating the bearing. Since the support plate 13 is supported on the outer wall of the large-diameter pipe 5 and cannot rotate, the rotation of the supporting nut 10 can be converted into axial linear motion of the screw rod 11 by means of thread transmission, so that the screw rod 11 moves upward or downward, thereby adjusting the supporting height of the large-diameter pipe 5 by the support plate 13, thereby coordinating the winding and releasing of the pipe fixing rope 15 to adjust the angle and height of the base frame 16 relative to the large-diameter pipe 5, so as to ensure that the large-diameter valve 6 subsequently placed on a pair of support rails 7 can be in a coaxial state with the large-diameter pipe 5.

[0045] Preferably, the support plate 13 may be a curved plate that matches the outer diameter of the large-diameter pipe 5 , so as to better fit the outer wall of the large-diameter pipe 5 and further improve the support stability.

[0046] Please see attached Figure 5 The support plate 13 is provided with a gasket 12 so that the support plate 13 abuts against the outer wall of the large-diameter pipe 5 through the gasket 12 .

[0047] Preferably, the gasket 12 may be a rubber pad, which can play an anti-slip role and ensure stable contact between the support plate 13 and the large-diameter pipe 5.

[0048] Please see attached Figure 1 To Attachment Figure 5 The construction method of installing the large-diameter valve 6 on the large-diameter pipeline 5 using the utility model is:

[0049] The base frame 16 is placed at the bottom of the large diameter pipeline 5, a pair of support units are supported on both sides of the bottom of the large diameter pipeline 5, one end of the pipeline fixing cable 15 is fixedly connected to the lifting ring 17 through a clamping ring 14, and the other end of the pipeline fixing cable 15 is wound around the two-way self-locking manual winch 3.

[0050] The hand crank of the two-way self-locking manual winch 3 is turned to wind the pipe fixing rope 15 around the winch of the two-way self-locking manual winch 3, and the pipe fixing rope 15 is pressed downward on the top of the large-diameter pipe 5. The base frame 16 is reliably fixed on the large-diameter pipe 5 by the downward pressure of the pipe fixing rope 15 and the top support force of a pair of support units.

[0051] Since the pipeline fixing rope 15 and the supporting unit are staggered in the axial direction of the large-diameter pipeline 5, the length of the pipeline fixing rope 15 is adjusted by rotating the hand crank of the two-way self-locking manual winch 3, and at the same time, the supporting length of the screw rod 11 between the base frame 16 and the large-diameter pipeline 5 is adjusted by rotating the supporting nut 10, so that the longitudinal center axis of the base frame 16 is parallel to the axial direction of the large-diameter pipeline 5.

[0052] The large-diameter valve 6 is placed on a pair of support rails 7. Since the pair of support rails 7 are symmetrically arranged about the longitudinal central axis of the base frame 16, the axial direction of the large-diameter valve 6 is located on the same straight line as the axial direction of the large-diameter pipeline 5. The body frame 18 is moved by the pulley 8 to make the large-diameter valve 6 approach and fit to the flange of the large-diameter pipeline 5.

[0053] Rotate the large-diameter valve 6 and utilize the friction between the large-diameter valve 6 and the pair of support rails 7 to drive the pair of support rails 7 to rotate in the clamp 9, so that the large-diameter valve 6 can be smoothly rotated until the valve hole position is aligned with the flange hole position, and the large-diameter valve 6 and the large-diameter pipeline 5 can be connected by bolts and nuts.

[0054] After the large-diameter valve 6 is installed, the hand crank of the two-way self-locking manual winch 3 is rotated in the opposite direction to release the pipeline fixing rope 15, so that the large-diameter valve installation auxiliary bracket can be removed from the large-diameter pipeline 5.

[0055] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
