A pipe support frame

Abstract

The present invention belongs to the technical field of pipeline support, and in particular, relates to a pipeline support frame, including an anchoring base, a clamping assembly is fixedly installed on the upper end of the anchoring base, and also includes: a lifting and separation mechanism, a lifting confirmation mechanism, an intermittent starting mechanism, a support drive mechanism, and multiple groups of scraping and snow removal mechanisms. The present invention can intermittently control the pipeline to be lifted and separated from the support frame. This separation force will cause the ice layer bonded between the pipeline and the support frame to be stretched and sheared, destroying the internal structure of the ice layer, so that the ice layer breaks, and the friction between the pipeline and the support frame will be greatly reduced. When the pipeline is displaced due to thermal expansion and contraction, internal pressure changes or external forces, it can move more freely on the support frame, reducing pipeline damage caused by friction, and avoiding the problem that the stress in the pipeline cannot be released due to ice bonding between the pipeline and the support frame, which will cause pipeline deformation and rupture, thereby ensuring the safe operation of the pipeline.

Description

Technical Field

[0001] The invention belongs to the technical field of pipeline support, and in particular relates to a pipeline support frame. Background Art

[0002] The pipeline support frame is a structural device used to support the pipeline. It is used to bear the weight of the pipeline itself and the weight of the medium transported in the pipeline, prevent the pipeline from excessive deformation or sinking due to gravity, ensure that the pipeline remains stable in the designed position, avoid displacement of the pipeline during operation, and ensure the normal operation of the pipeline system.

[0003] During the operation of the pipeline, due to temperature changes, internal pressure changes and other reasons, there will be certain thermal expansion, contraction and displacement. Therefore, when designing the pipeline support frame, it is currently set as a sliding bracket to allow a certain displacement between the pipeline and the support frame to accommodate the length changes of the pipeline caused by thermal expansion and contraction and other reasons.

[0004] When using pipe support racks to install and support pipes in cold areas, water vapor in the air will condense on the surface of the pipe to form water droplets. When the temperature continues to drop, these water droplets will gradually freeze into ice. Because the pipe is in close contact with the support rack, the ice layer will continue to grow between the two, and eventually bond the pipe and the support rack together. As the ice layer thickens, the bonding force will gradually increase. When the temperature rises, the ice layer begins to melt, but because some water films will be produced during the melting process of the ice, these water films also play a certain bonding role between the pipe and the support rack, so that there is still a certain bonding force between the pipe and the support rack. This bonding force will hinder the normal movement of the pipe on the support rack. Because during the operation of the pipe, due to temperature changes, internal pressure changes and other reasons, a certain amount of thermal expansion and contraction and displacement will occur. If there is bonding force between the pipe and the support rack, it will limit the movement of the pipe, resulting in additional stress inside the pipe, and when the pipe tries to overcome the bonding force and move, friction will occur between the pipe surface and the support rack. If the pipe has an anti-corrosion layer, this friction will directly damage the anti-corrosion layer, exposing the pipe to the external environment, accelerating the corrosion of the pipe, and affecting the stable use of the pipe.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] By means of the provided lifting and separation mechanism, clamping assembly, lifting-in-place confirmation mechanism and intermittent starting mechanism, the pipeline can be intermittently controlled to be lifted and separated from the support frame. This separation force will stretch and shear the ice layer bonded between the pipeline and the support frame, destroy the internal structure of the ice layer, and break the ice layer. After the ice bonding is broken, the friction between the pipeline and the support frame will be greatly reduced. When the pipeline is displaced due to thermal expansion and contraction, internal pressure changes or external forces, it can move more freely on the support frame, reducing damage to the pipeline caused by friction, and avoiding the problem of ice bonding between the pipeline and the support frame causing the stress in the pipeline to be unable to be released, which will in turn cause the pipeline to deform and rupture, thereby ensuring the safe operation of the pipeline.

[0026] Through the support driving mechanism, scraping snow removal mechanism, knocking ice removal mechanism and power supply trigger mechanism, when the pipeline is lifted and separated from the support frame, the weight of the pipeline can be detected synchronously, and it can automatically determine whether there is snow and ice covering the pipeline, and automatically choose to start the snow scraping process on the pipeline. When ice is detected during the snow scraping process, the ice can be automatically cleared, and the pipeline can be quickly cleaned to avoid the problem of bending and deformation of the pipeline caused by excessive pressure on the pipeline, and the pressure on the support frame is reduced, making the support of the pipeline more stable.

[0027] Through the set ambient temperature sensing feedback mechanism, the ambient temperature can be automatically monitored, and the lifting interval time of the pipeline and the frequency of ice cleaning on the pipeline surface can be automatically adjusted based on the ambient temperature. The lower the ambient temperature, the shorter the lifting interval time. Because the lower the temperature, the faster the water freezes, and the low temperature will cause the water molecules to arrange more orderly to form an ice crystal structure. Therefore, it is necessary to separate the pipeline and the support frame more frequently to destroy the ice layer. The lower the temperature, the faster the freezing speed, which will cause the thickness of the ice on the pipeline surface to be greater. At this time, a higher knocking frequency is used to quickly destroy the ice layer, thereby improving the quality and efficiency of pipeline cleaning. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] The PLC controller 11 is fixedly mounted on the outer wall of the clamping assembly 10, and is respectively electrically connected to the lifting and separation mechanism 2, the lifting-in-place confirmation mechanism 3, the intermittent starting mechanism 4, the supporting driving mechanism 5, the scraping and snow removal mechanism 6, the knocking and ice removal mechanism 7, the power supply trigger mechanism 8 and the ambient temperature sensing feedback mechanism 9.

[0050] The operating principle of the present invention is described as follows: the pipeline is fixedly installed on the anchor base 1 through the clamping assembly 10 [a gap is left between the clamping assembly 10 and the pipeline, which is mainly for supporting force. The clamping assembly 10 is the cooperation of the existing upper clamping plate and the lower clamping plate, which is the existing technology and will not be described in detail here]. The PLC controller 11 controls the drive motor 43 to operate, and the drive motor 43 drives the reciprocating screw rod 42 to rotate. The reciprocating plate 44 moves in the starting shell 41 through the threaded sleeve effect of the reciprocating screw rod 42 and the reciprocating plate 44 until the reciprocating plate 44 presses on the starting switch 45. The starting switch 45 feeds back a signal to the PLC controller 11, and the PLC controller 11 controls the hydraulic cylinder 21 to operate. The hydraulic cylinder 21 drives the two arc-shaped supporting plates through the lifting plate 22 23 moves up synchronously, and the arc-shaped supporting plate 23 uses the top thrust of the supporting spring 25 to lift the pipe [for a small lifting height of the pipe, only a 2cm gap is needed between the pipe and the bottom of the inner wall of the clamping assembly 10 to allow air to circulate, because the pipe itself has a certain deformation ability, so it will not affect other positions of the pipe], so that the pipe and the clamping assembly 10 are separated. When the arc-shaped supporting plate 23 drives the pipe to move up, it drives the confirmation plate 32 to move up synchronously until the confirmation plate 32 presses on the confirmation switch 31, indicating that the pipe and the clamping assembly 10 are completely separated. At this time, the PLC controller 11 controls the hydraulic cylinder 21 to stop the action, destroying the ice adhesion between the pipe and the clamping assembly 10, and ensuring the safe operation of the pipe;

[0051] After the pipe is completely separated from the clamping assembly 10, wait for 3 seconds. After the pipe is relatively stable, the PLC controller 11 detects whether the trigger switch 27 is pressed and triggered. If the weight of the lifted pipe is greater than the weight of the pipe itself, the arc-shaped supporting plate 23 will be subjected to greater pressure, which will in turn cause greater compression on the support spring 25, thereby causing the arc-shaped supporting plate 23 to move a greater distance relative to the lifting plate 22, thereby driving the pushing rod 28 and the pushing plate 29 to move a greater distance relative to the trigger switch 27, so that the pushing plate 29 presses on the trigger switch 27, indicating that the section of the pipe is covered with snow and ice. More snow and ice will have a greater impact on the pipe. The pipe is lifted up at this time, so the upper outer wall of the pipe collides with the multiple snow scrapers 63 in the semicircular positioning plate 56. The PLC controller 11 controls the double-axis motor 53 to move forward first, and the double-axis motor 53 drives the two rotating screws 54 to rotate forward. The driving seat 55 drives the semicircular positioning plate 56 to move through the threaded connection between the rotating screw 54 and the driving seat 55, thereby driving the multiple snow scrapers 63 to move on the outer surface of the pipe to scrape off the snow attached to the outside of the pipe. When the snow scraper 63 encounters an ice layer while moving, the snow scraper 63 When the deflection shaft 62 is rotated to overcome the elastic force of the torsion spring 64, the snow scraper 63 is deflected, so that the snow scraper 63 passes over the ice layer. When the deflection shaft 62 rotates, the feedback conductive block 66 is driven to move in the circular cover 65, so that the feedback conductive block 66 contacts the feedback electrical connection strip 67. The feedback conductive block 66 and the feedback electrical connection strip 67 feed back electrical signals to the PLC controller 11. The PLC controller 11 controls the power supply device to supply power to the thrust electromagnetic plate 77, and synchronously controls the action of the servo motor 83. The servo motor 83 drives the power conductive block 85 to move in the trigger circular shell 81 through the transmission shaft 82, and the power conductive block 85 and the power conductive block 85 are in contact with each other. 84 is connected in series to the power supply circuit of the thrust electromagnetic plate 77. When the power supply conductive block 85 contacts the power supply electrical connection block 84, the power supply circuit of the thrust electromagnetic plate 77 is connected, and the thrust electromagnetic plate 77 is energized to generate the same magnetism as the thrust permanent magnet plate 76, so that the knocking rod 71 overcomes the elastic force of the reset spring 74 and drives the knocking head 72 to move downward to act on the ice layer on the outer surface of the pipeline, exerting a knocking vibration force on the ice layer to break the ice layer. When the power supply conductive block 85 leaves the power supply electrical connection block 84, the power supply to the thrust electromagnetic plate 77 is cut off, and the knocking head 72 is moved up and reset under the action of the reset spring 74, thereby realizing high-frequency knocking of the knocking head 72 on the ice layer, breaking and cleaning the ice layer.

[0052] The temperature sensor 58 monitors the temperature of the environment in real time and feeds back a signal to the PLC controller 11. When the ambient temperature is lower, the PLC controller 11 controls the power supply device to supply a larger current to the force electromagnetic plate 96. The force electromagnetic plate 96 generates a magnetic force that is the same as but greater than the force permanent magnet plate 95 when it is energized, thereby pushing the sliding plate 93 to move a longer distance along the limit slide rod 92 to overcome the elastic force of the push-back spring 94, so that the conductive contact 98 slides a greater distance on the resistor rod 97, thereby making the access resistance of the resistor rod 97 smaller, and the conductive contact 98 and the resistor rod 97 are connected in series to the power supply circuit of the drive motor 43. The drive motor 43 is a DC motor, so the speed of the drive motor 43 is faster, the frequency of the start switch 45 being pressed and triggered is higher, and the frequency of the pipeline being lifted and separated from the clamping assembly 10 is higher, which is suitable for the situation where the temperature is lower and the freezing speed is faster;

[0053] The conductive contact piece 98 and the resistor rod 97 are also connected in series to the power supply circuit of the servo motor 83. The servo motor 83 is a DC motor. When the ambient temperature is lower, the resistance of the resistor rod 97 is smaller, and the rotation speed of the servo motor 83 is higher, so that the contact frequency between the power supply conductive block 85 and the power supply electrical connection block 84 is higher, and the knocking frequency of the knocking head 72 on the outer surface of the pipeline is higher, thereby improving the knocking and cleaning intensity of the ice layer, which is suitable for the situation where the temperature is lower, the ice thickness of the ice layer on the outer surface of the pipeline is greater, and the ice layer strength is higher;

[0054] In the mining and production of coal mines in cold areas (such as the coal mines in Hulunbuir, Inner Mongolia, where the winter is long and cold), the temperature in Hulunbuir is extremely low in winter. Some pipes underground in the coal mines, such as drainage pipes and ventilation pipes, are easily affected by the low temperature and freeze. The use of the pipe support frame of the present application in coal mines in cold areas can effectively solve the various problems caused by the freezing of pipes and ensure the normal production and operation of the coal mines.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
