Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0034] like Figure 1 As shown, the present application provides a pipeline conveying device, and an embodiment of the pipeline conveying device of the present application includes: a base frame 10, a placement frame 20, a clamping assembly 30 and an auxiliary support plate 40. Among them, the placement frame 20 is arranged above the base frame 10; the clamping assembly 30 is arranged in the placement frame 20, and the clamping assembly 30 includes a first clamping portion 31 and a second clamping portion 32, the first clamping portion 31 and the second clamping portion 32 are arranged relatively along a first preset direction a and form a clamping space 100 for placing the pipeline to be transported, and the axis of the pipeline to be transported extends along a second preset direction b, and the second preset direction b is perpendicular to the first preset direction a; the auxiliary support plate 40 is movably arranged on the placement frame 20 along the second preset direction b and is located below the clamping assembly 30, and the auxiliary support plate 40 has a storage position and an extended position. When the auxiliary support plate 40 is in the extended position, the auxiliary support plate 40 extends outward from the placement frame 20 and is used to support the pipeline to be transported.

[0035] By applying the technical solution of this embodiment, the clamping assembly 30 is arranged on the placement rack 20 and has a clamping space 100. The pipeline to be transported is placed in the clamping space 100 and can be limited by the clamping assembly 30 to prevent the pipeline to be transported from rolling and falling, thereby ensuring the safety of the conveyor belt transport pipeline. The auxiliary support plate 40 is movably arranged along the second preset direction b (i.e., the extension direction of the transport pipeline) and is located below the clamping assembly 30. When the pipeline to be transported is long and the rigidity of the pipeline itself is relatively poor, the auxiliary support plate 40 is moved to the extended position, thereby lengthening the length of the pipeline conveying device supporting the pipeline to be transported, thereby being able to lift the end of the pipeline to be transported off the ground, avoiding friction caused by the end of the pipeline to be transported dragging on the ground, which affects the smoothness of transportation or wears the pipeline to be transported. Therefore, the technical solution of this embodiment can effectively solve the problem in the related art that the long pipeline dragging on the ground increases the difficulty of transportation and the pipeline is easy to wear.

[0036] Specifically, the pipeline to be transported in this embodiment can be a long-distance transmission pipeline for liquid carbon dioxide. Spontaneous combustion of coal fires, as one of the global disasters, threatens human health and safe production in coal mines, causing resource loss and environmental pollution. Among the existing coal mine fire prevention and extinguishing technical methods, the liquid carbon dioxide method has great advantages in the management of mine fire areas because it can achieve rapid cooling on the basis of inerting. The gaseous carbon dioxide entering the delivery pipe can effectively increase the pressure of the delivery pipe, providing pressure conditions for the transportation of liquid carbon dioxide; by setting a pressure control valve, the gaseous carbon dioxide or liquid carbon dioxide with a pressure greater than 2MPa to 2.5MPa in the delivery pipe can be discharged, wherein, when liquid carbon dioxide is injected, the leaked liquid carbon dioxide enters the underground fire area through the fire extinguishing pipe for fire extinguishing.

[0037] like Figure 1 , Figure 2 and Figure 4 As shown, there are two auxiliary support plates 40, one of which moves along the positive direction of the second preset direction b to switch from the storage position to the extended position, and the other auxiliary support plate 40 moves along the negative direction of the second preset direction b to switch from the storage position to the extended position. Specifically, two auxiliary support plates 40 are respectively extended from the opposite sides of the clamping assembly 30 to support the pipeline to be transported, so as to ensure that the clamping assembly 30 for fixing the pipeline to be transported clamps the middle part of the pipeline to be transported, and ensure the stability of the limit position during transportation.

[0038] like Figure 1 , Figure 2 and Figure 4 As shown, the placement rack 20 is provided with a receiving groove 21 and a slide groove 22 connected to the receiving groove 21, and the auxiliary support plate 40 includes a main plate 41 and a first slider 42 provided on the side of the main plate 41, the main plate 41 is movably provided in the receiving groove 21, and the first slider 42 is movably provided in the slide groove 22. The movement of the main plate 41 is guided and supported by the sliding cooperation between the first slider 42 and the slide groove 22, so as to ensure the stability of the main plate 41 during the movement.

[0039] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a locking groove 211 is provided on the upper surface and / or the lower surface of the receiving groove 21, and an elastic locking member 43 is provided on the main plate 41. When the auxiliary support plate 40 is in the extended position, the elastic locking member 43 engages with the locking groove 211 to keep the auxiliary support plate 40 in the extended position. Specifically, the elastic locking member 43 is located at the inner end of the main plate 41 (that is, at the inner end of the main plate 41). Figure 1The middle main body plate 41 is located at one end of the middle part of the placement rack 20, and the positioning groove 211 is located at the outer end of the placement rack 20 (that is, at the Figure 1 When the auxiliary support plate 40 moves to the extended position, the elastic locking member 43 is locked into the locking groove 211 to limit the further outward movement of the main plate 41, thereby ensuring that the auxiliary support plate 40 can be stably maintained in the extended position.

[0040] like Figure 5 and Figure 6 As shown, a mounting hole 411 is provided on the main body plate 41. The mounting hole 411 includes a first hole section 4111 and a second hole section 4112 that are interconnected. The second hole section 4112 is located on the outside of the first hole section 4111. The aperture of the first hole section 4111 is larger than the aperture of the second hole section 4112. The elastic retaining member 43 includes a retaining block 431, a mounting plate 432 and a first elastic member 433. The first elastic member 433 and the retaining block 431 are respectively located on both sides of the mounting plate 432. The mounting plate 432 and the first elastic member 433 are both arranged in the first hole section 4111. The first elastic member 433 presses against the mounting plate 432 outwardly so that the retaining block 431 extends outwardly from the second hole section 4112. The mounting plate 432 cooperates with a step surface stopper formed between the first hole section 4111 and the second hole section 4112 to limit the elastic retaining member 43 from being separated from the mounting hole 411. Specifically, the "outside" in the description of the elastic retaining member 43 refers to the area close to the mounting plate 432. Figure 5 The "inner side" refers to the side away from the upper and lower end surfaces of the main body plate 41. Figure 5 In the embodiment, the mounting hole 411 includes a first hole section 4111 and two second hole sections 4112 respectively located at the upper and lower sides of the first hole section 4111, and the elastic clamping member 43 includes a plurality of first elastic members 433 (specifically compression springs) located in the first hole section 4111, two mounting plates 432 connected at both ends of the plurality of first elastic members 433, and two clamping blocks 431 installed on the outer sides of the two mounting plates 432. Among them, the clamping block 431 has a hemispherical end surface to reduce the friction between the clamping block 431 and the groove wall of the receiving groove 21 when the auxiliary support plate 40 moves in the receiving groove 21, and at the same time, it is convenient for the staff to push and pull the auxiliary support plate 40 so that the elastic clamping member 43 is out of the state of being engaged with the clamping groove 211, thereby facilitating the staff to store the auxiliary support plate 40 in the interior of the placement rack 20.

[0041] like Figure 1 , Figure 2 and Figure 5As shown, the outer end of the main plate 41 is provided with an operating groove 412. When the auxiliary support plate 40 needs to be moved from the storage position to the extended position, the staff can put their hands into the operating groove 412 to pull the auxiliary support plate 40 outward. Specifically, the thickness of the portion of the main plate 41 corresponding to the outer side of the operating groove 412 is less than the height of the receiving groove 21 (see Figure 2 ), so that the staff's hand can reach into the operating groove 412 through the gap between the main plate 41 and the accommodating groove 21 to pull the auxiliary support plate 40.

[0042] like Figure 3 As shown, the first preset direction a is a transverse direction, the first clamping portion 31 is movably arranged along the first preset direction a, and the pipeline conveying device further includes a first buffer structure 50 arranged between the placement rack 20 and the first clamping portion 31. When a collision occurs during transportation, the first clamping portion 31 can move along the first preset direction a and absorb part of the impact through the first buffer structure 50, thereby protecting the pipeline to be transported and the clamping assembly 30.

[0043] like Figure 3 As shown, the first buffer structure 50 includes a second elastic member 51 extending along the first preset direction a, so that the first clamping portion 31 is maintained at the position of the closed clamping space 100. The second elastic member 51 is a compression spring, and the second elastic member 51 abuts against the first clamping portion 31 so that the first clamping portion 31 can be maintained at the position of the closed clamping space 100 when not impacted. After being impacted, the second elastic member 51 is compressed to absorb part of the impact force, and then the second elastic member 51 is reset to restore the first clamping portion 31 to the position of the closed clamping space 100.

[0044] like Figure 3 As shown, the first buffer structure 50 includes a third elastic member 52 disposed on the first clamping portion 31 and extending in the vertical direction, a second slider 53 disposed at one end of the third elastic member 52, and a movable rod 54 hinged to the second slider 53 and the placement frame 20 at both ends. The third elastic member 52 pushes against the second slider 53 to keep the first clamping portion 31 in the position of the closed clamping space 100. The third elastic member 52 is a compression spring. Figure 3 Taking the third elastic member 52 in the upper left corner and the second slider 53 and movable rod 54 connected thereto as an example, after being impacted, the first clamping portion 31 moves to the right and drives the movable rod 54 to swing counterclockwise around the hinge point on the left, and the second slider 53 moves up along the slide rod and compresses the third elastic member 52, thereby absorbing part of the impact force. Thereafter, the third elastic member 52 is reset to cause the second slider 53 to move downward, thereby driving the movable rod 54 to swing clockwise around the hinge point on the left and press against the first clamping portion 31 to the left, causing the first clamping portion to return to the position of the closed clamping space 100.

[0045] A third elastic member 52, a second slider 53 and a movable rod 54 that cooperate with each other form a group of buffer components. Two groups of buffer components are connected between the first clamping part 31 and the placement rack 20. The two groups of buffer components are respectively located on the upper and lower sides of the second elastic member 51. The setting of the two groups of buffer components makes the left and right movement of the first clamping part 31 more stable, and plays an auxiliary role in the adjustment activity of the first clamping part 31, so that the first clamping part 31 can move stably, thereby further improving the stability of the first clamping part 31 and the second clamping part 32 in limiting the clamping of the transport pipeline to be transported, and avoiding the problem of the transport pipeline rolling down.

[0046] like Figure 3 As shown, the second clamping portion 32 is movably arranged along the first preset direction a, and a second elastic member 51 and two groups of buffer components are also arranged between the second clamping portion 32 and the placement rack 20. The specific arrangement is the same as the arrangement of the second elastic member 51 and the two groups of buffer components on the left side of the first clamping portion 31, and will not be repeated here.

[0047] like Figure 3 As shown, the two second elastic members 51 respectively press against the first clamping portion 31 and the second clamping portion 32 from the left and right sides, thereby ensuring the clamping force of the first clamping portion 31 and the second clamping portion 32, and ensuring that the first clamping portion 31 and the second clamping portion 32 clamp and limit the two sides of the pipeline to be transported placed in the clamping space 100. At the same time, a plurality of pipelines to be transported with relatively small diameters can also be arranged inside the clamping space 100.

[0048] like Figure 1 As shown, the base frame 10 includes a moving seat 11 and a mounting seat 12 disposed on the moving seat 11, the placement rack 20 is disposed on the mounting seat 12, and a second buffer structure 13 is disposed between the mounting seat 12 and the moving seat 11. The second buffer structure 13 is disposed between the mounting seat 12 and the moving seat 11, and the second buffer structure 13 can absorb the impact of the ground on the moving seat 11 during movement, thereby reducing the impact on the placement rack 20 and the pipeline to be transported clamped between the clamping assemblies 30.

[0049] like Figure 1 As shown, a mounting groove 111 is provided on the movable seat 11, and the mounting seat 12 is arranged in the mounting groove 111, wherein the second buffer structure 13 includes a plurality of fourth elastic members 131 arranged between the bottom surface of the mounting seat 12 and the bottom wall of the mounting groove 111, and the fourth elastic member 131 is a compression spring, and the fourth elastic member 131 can absorb impacts along the vertical direction.

[0050] like Figure 1 and Figure 2As shown, the second buffer structure 13 includes a floating buffer member disposed between the side wall of the mounting seat 12 and the side wall of the mounting groove 111, the floating buffer member includes a sleeve 132, a slide bar 133 disposed in the sleeve 132, and a fifth elastic member 134 disposed between the slide bar 133 and the sleeve 132, the end of the sleeve 132 is hingedly connected to the side wall of the mounting groove 111, and the end of the slide bar 133 is hingedly connected to the side wall of the mounting seat 12. The floating buffer member extends in the transverse direction, wherein the fifth elastic member 134 is a compression spring, and the floating buffer member can absorb impacts along the transverse direction. In addition, the two ends of the floating buffer are respectively hingedly connected to the side walls of the mounting seat 12 and the side walls of the mounting groove 111, so that the mounting seat 12 can move in the vertical direction relative to the mounting groove 111, and the mounting seat 12 can move in multiple directions in the mounting groove 111, and the second buffer structure 13 can buffer the movement of the mounting seat 12 in various directions, so that the pipeline conveying device can adapt to the conveying work under various rugged road conditions.

[0051] like Figure 1 As shown, the base frame 10 also includes a push frame 14 connected to the moving seat 11 and a moving wheel 15 arranged below the moving seat 11. The setting of the moving wheel 15 facilitates the staff to move the pipeline conveying device, and the setting of the push frame 14 facilitates the staff to drive the pipeline conveying device to move by pushing the push frame 14. The push frame 14 is a frame structure, and the auxiliary support plate 40 arranged near the push frame 14 and the pipeline to be transported can be moved to the Figure 1 The left side in the middle extends out of the push frame 14.

[0052] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
