DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 , the utility model provides a technical solution:

[0022] A supporting device for a petrochemical pipeline comprises a lifting assembly 1, a lifting base 2 and a supporting ring 5, wherein the top surface of the lifting base 2 is provided with an adjusting assembly; the adjusting assembly comprises an adjusting frame 3, wherein an adjusting cavity 6 is provided in the adjusting frame 3, wherein a positioning shaft 4 is inserted in the adjusting cavity 6 so as to be horizontally slidable and radially rotatable; the positioning shaft 4 is fixedly connected with a positioning plate 7 in the adjusting frame 3, wherein a positioning tooth 8 is provided in the adjusting frame 3, wherein mutually engaging protrusions are provided on the positioning plate 7 and the positioning tooth 8, and when the positioning plate 7 conflicts with the positioning tooth 8, the positioning shaft 4 cannot rotate.

[0023] When the pitch angle of the support ring 5 needs to be adjusted, the positioning shaft 4 is first pushed inward to disengage the positioning plate 7 from the positioning teeth 8 .

[0024] At this time, the positioning shaft 4 and the supporting ring 5 thereon can rotate horizontally around the axis of the adjustment frame 3 to adjust the pitch angle of the pipeline.

[0025] After the adjustment is completed, the positioning shaft 4 is pulled outwards so that the positioning plate 7 contacts the positioning teeth 8 again, and the pitch angle can be locked.

[0026] Thus, through the above operation, the pitch angle adjustment of the support ring 5 is realized to adapt to the inclination angles between different oil pipeline sections and the ground. There is no need to customize different batches according to their inclination angles at the factory, making the use of the support device more convenient.

[0027] Furthermore, a push rod 10 is threadedly connected to the other side of the adjustment frame 3 , and a top plate 9 is slidably connected to the adjustment frame 3 , and the top plate 9 is located between the push rod 10 and the positioning plate 7 .

[0028] A limiting sleeve 14 is provided on one side where the adjusting frame 3 is threadedly connected to the push rod 10. A movable clamping plate 12 is provided in the limiting sleeve 14 so as to be only horizontally slidable. A spring 13 is provided between the movable clamping plate 12 and the limiting sleeve 14. A clamping plate 11 is provided on the outer wall of the push rod 10. The clamping plate 11 is provided in the limiting sleeve 14 in the shape of a disc. When the movable clamping plate 12 conflicts with the clamping plate 11, the push rod 10 cannot rotate.

[0029] A through slot is formed on the top surface of the limiting sleeve 14 , and a protrusion is formed on the top surface of the movable clamping plate 12 . The protrusion passes through the through slot and is disposed above the limiting sleeve 14 .

[0030] The same through hole is opened on the side of the limiting sleeve 14 away from the adjusting frame 3 and the movable clamping plate 12. The back of the top rod 10 is connected to one end of the extension rod. The other end of the extension rod extends out of the through hole and is arranged on the outside of the limiting sleeve 14. A hexagonal rotating block is arranged on the other end of the extension rod.

[0031] By adopting the above design, after the adjustment is completed, the top plate 9 can be pushed forward by rotating the top rod 10, limiting the horizontal movement space of the positioning plate 7, making it impossible to separate from the positioning teeth 8, thereby achieving the pitch angle locking of the support ring 5.

[0032] Furthermore, a card plate 11 is provided on the top rod 10, and a movable card plate 12 and a spring 13 are provided in the limiting sleeve 14, so that unless the staff manually pushes the movable card plate 12 to separate it from the card plate 11, the movable card plate 12 will always maintain a tight contact with the card plate 11 under the push of the spring 13, thereby preventing the top rod 10 from being rotated out of the adjustment frame 3 and ensuring the stability of the pitch angle locking.

[0033] Furthermore, the support ring 5 includes a connecting ring 501 and a separating ring 502. The lower end of the connecting ring 501 is fixedly connected to the side wall of the positioning shaft 4. One side of the connecting ring 501 is rotatably connected to the separating ring 502 via a rotating shaft, and the other side is clamped to the separating ring 502 via a clamping assembly.

[0034] The snap-on assembly includes a docking plate arranged at the other end of the connecting ring 501, and a mounting plate arranged at the other end of the separating ring 502. The mounting plate is provided with a transverse groove connected to its top and bottom surfaces. An insert block is slidably connected in the transverse groove. One end of the insert block is L-shaped and arranged on the bottom surface of the mounting plate. A retaining spring is arranged between the back side of the insert block and the transverse groove. The docking plate is provided with an L-shaped slot connected to its top surface.

[0035] When it is necessary to install or remove the pipe, the insert block can be pressed to slide along the transverse groove and compress the retaining spring until the insert block is completely withdrawn from the L-shaped groove.

[0036] At this time, the separation ring 502 can rotate around the rotation axis and separate from the connection ring 501, and the support ring 5 is opened.

[0037] After the pipeline is installed, the connecting ring 501 is turned back, and after the insert block is reinserted into the L-shaped slot, the insert block is released, and the retaining spring pushes the insert block to re-enter the L-shaped slot, thereby closing and fixing the support ring 5 .

[0038] The openable and closed design of the support ring 5 makes the installation and removal of the pipeline more convenient, and also facilitates the maintenance and repair of the support device.

[0039] Specifically, the lifting assembly 1 includes a sleeve, a limit block, a motor and a screw rod. The motor is fixedly installed at the bottom end of the sleeve, the output shaft of the motor is fixedly connected to the screw rod, the limit block can be vertically slidably arranged in the sleeve, and the bottom end of the limit block is threadedly connected to the screw rod.

[0040] When the height of the pipeline needs to be adjusted, the motor in the lifting assembly 1 is started, and the motor drives the screw rod to rotate.

[0041] Since the stop block is threadedly connected to the lead screw and can slide vertically in the outer sleeve, the rotation of the lead screw is converted into vertical movement of the stop block.

[0042] The vertical movement of the limit block can drive the supporting device including the lifting base 2, the adjustment component and the supporting ring 5 to rise or fall, so as to support the petrochemical pipelines at different heights.

[0043] Through the design of the lifting component 1 and the adjusting component, flexible adjustment of the pipeline height and pitch angle is achieved, thereby improving the adaptability and flexibility of the pipeline system.

[0044] The outer jacket is provided with a ground nail groove, in which a long strip-shaped connecting opening is opened. There are four ground nail grooves respectively arranged at the bottom ends of the four side walls of the outer jacket.

[0045] The design of the ground nail groove allows the installation of the lifting assembly 1 to be more stable by driving ground nails above the ground nail groove after the installation is completed.

[0046] Through the design of the ground nail groove, the support device can be firmly fixed on different types of ground, enhancing its adaptability in complex terrain environments.

[0047] Working principle:

[0048] First, press the insert to slide along the horizontal groove and compress the retaining spring until the insert is completely removed from the L-shaped groove.

[0049] At this time, the separation ring 502 can rotate around the rotation axis and separate from the connection ring 501, and the support ring 5 is opened.

[0050] Then, the positioning shaft 4 is pushed inwards to disengage the positioning plate 7 from the positioning teeth 8 .

[0051] At this time, the positioning shaft 4 and the supporting ring 5 thereon can rotate horizontally around the axis of the adjustment frame 3 to adjust the pitch angle of the pipeline.

[0052] After the adjustment is completed, the positioning shaft 4 is pulled outwards so that the positioning plate 7 contacts the positioning teeth 8 again, and the pitch angle can be locked.

[0053] Next, the rotating push rod 10 pushes the top plate 9 forward, limiting the horizontal movement space of the positioning plate 7 so that it cannot be separated from the positioning teeth 8, thereby achieving the locking of the pitch angle of the support ring 5.

[0054] Finally, the motor in the lifting assembly 1 is started, and the motor drives the lead screw to rotate.

[0055] Since the stop block is threadedly connected to the lead screw and can slide vertically in the outer sleeve, the rotation of the lead screw is converted into vertical movement of the stop block.

[0056] The vertical movement of the limit block can drive the supporting device including the lifting base 2, the adjustment assembly and the supporting ring 5 to rise.

[0057] After the connecting ring 501 contacts the bottom end of the pipe, the connecting ring 501 can be turned back, and the plug block can be pressed again. After the plug block is reinserted into the L-shaped slot, the plug block is released, and the retaining spring pushes the plug block to re-enter the L-shaped slot, thereby closing and fixing the support ring 5.

[0058] After the installation is completed, ground nails can be driven into the ground nail grooves to make the installation of the lifting assembly 1 more stable.
