Description

Technical Field

[0001] This application relates to the technical field of pipeline erection, and more specifically, to a transportation limit adjustment system for pipeline erection. Background Art

[0002] Most of the existing pipeline transportation limit adjustment system technologies are fixed supports and adjustable supports in one plane. In underground tunnels, there is no implementation case for a transportation limit adjustment system for low-vacuum pipelines. When the existing pipeline transportation limit adjustment system is used for the erection of vacuum pipelines in underground tunnels, there are problems that the existing pipeline transportation limit adjustment system is complex, occupies a large space, and is not suitable for the erection of vacuum pipelines in underground tunnels. There is also a problem that the adjustment direction is only unidirectional.

[0003] Therefore, the existing transportation limit adjustment system for pipeline erection has a complex structure and can only be adjusted unidirectionally, which is a technical problem that needs to be urgently solved by those skilled in the art.

[0004] The above information disclosed in the background art is only used to enhance the understanding of the background of this application. Therefore, it may include information on prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0006] Embodiments of this application provide a transportation limit adjustment system for pipeline erection, including:

[0007] Two guide blocks, the two guide blocks are fixedly spaced in the transverse direction, and the preset guiding direction of the two guide blocks is the longitudinal direction along the upper surface of the guide block and perpendicular to the transverse direction;

[0008] A longitudinal displacement adjustment member is placed on the upper surfaces of the two guide blocks, and the longitudinal displacement adjustment member can move along the longitudinal direction on the upper surfaces of the guide blocks;

[0009] A transverse displacement adjustment member is used to carry the pipeline, is placed on the longitudinal displacement adjustment member and can move along the longitudinal direction with the longitudinal displacement adjustment frame, and the transverse displacement member can also drive the pipeline to move along the transverse direction.

[0010] Embodiments of this application have the following technical effects due to the above technical solutions:

The longitudinal displacement adjustment member is placed on the two guiding blocks and can move along the longitudinal direction on the upper surface of the guiding blocks, that is, the longitudinal displacement adjustment member can move along the length direction of the tunnel on the upper surface of the guiding blocks. Since the transverse displacement adjustment member is placed on the longitudinal displacement adjustment member and can move along the longitudinal direction with the longitudinal displacement adjustment member, at the same time, the transverse displacement member can also drive the pipeline to move along the transverse direction. In this way, when the pipeline is carried by the transverse displacement adjustment member, the transverse displacement member can drive the pipeline to move along the transverse direction, that is, the pipeline can move in the width direction of the tunnel; in addition, when the longitudinal displacement adjustment member moves along the length direction of the tunnel, it also drives the transverse displacement member and the pipeline to move in the length direction of the tunnel, realizing that the pipeline can move in two directions, namely the width direction and the length direction of the tunnel, and can conveniently realize the adjustment and positioning of the pipeline in the tunnel.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0029] The transportation limit adjusting system for erecting pipelines of the present invention belongs to the technical field of low-vacuum pipeline transportation, and is particularly applicable to the transportation limit adjusting system for erecting low-vacuum pipelines in underground tunnels.

[0030] Embodiment 1

[0031] Figure 1 Schematic diagram of a transportation limit adjusting system for erecting pipelines according to an embodiment of the present application

[0032] As shown in the figure, a transportation limit adjusting system for erecting pipelines according to an embodiment of the present application includes:

[0033] Two guiding blocks 1, the two guiding blocks 1 are fixedly spaced in the lateral direction, and the preset guiding direction of the two guiding blocks 1 is the longitudinal direction along the upper surface of the guiding block and perpendicular to the lateral direction;

[0034] A longitudinal displacement adjusting member 2, placed above the upper surfaces of the two guiding blocks 1, and the longitudinal displacement adjusting member can move along the longitudinal direction on the upper surface of the guiding block;

[0035] A lateral displacement adjusting member 3, used to carry the pipeline, placed above the longitudinal displacement adjusting member 2 and can move along the longitudinal direction with the longitudinal displacement adjusting framework, and the lateral displacement member can drive the pipeline to move along the lateral direction.

[0036] When the transportation limit adjustment system for erecting pipelines in the embodiments of the present application is used for erecting pipelines in an underground tunnel, the two guiding blocks are fixed on the inner bottom surface of the underground tunnel, and the two guiding blocks are fixedly spaced in the width direction of the tunnel, that is, the lateral direction is consistent with the width direction of the tunnel, and the preset guiding direction longitudinal direction of the two guiding blocks is consistent with the length direction of the tunnel. The longitudinal displacement adjusting member is placed above the two guiding blocks and can move along the longitudinal direction on the upper surface of the guiding block, that is, the longitudinal displacement adjusting member can move along the length direction of the tunnel on the upper surface of the guiding block. Since the lateral displacement adjusting member is placed above the longitudinal displacement adjusting member and can move along the longitudinal direction with the longitudinal displacement adjusting framework, at the same time, the lateral displacement member can also drive the pipeline to move along the lateral direction. In this way, when the pipeline is carried by the lateral displacement adjusting member, the lateral displacement member can drive the pipeline to move along the lateral direction, that is, the pipeline can move in the width direction of the tunnel; in addition, when the longitudinal displacement adjusting member moves along the length direction of the tunnel, it drives the lateral displacement member and the pipeline to move in the length direction of the tunnel, realizing that the pipeline can move in two directions, the width direction and the length direction of the tunnel, and can conveniently realize the adjustment and positioning of the pipeline in the tunnel. The transportation limit adjustment system in the embodiments of the present application realizes the adjustment of the displacement of the pipeline in two dimensions, the lateral direction and the longitudinal direction, through a simple structure, and can conveniently realize the adjustment and positioning of the pipeline.

[0037] Figure 2 is Figure 1 a schematic diagram of the cooperation between the longitudinal displacement adjusting member and the guiding block of the transportation limit adjustment system shown; Figure 3 is Figure 2 another perspective schematic diagram of. As Figure 2 and Figure 3 shown, regarding the structure of the guiding block, it is described as follows:

[0038] In implementation, as shown in the figure, the upper surfaces of the two guiding blocks 1 are inclined upper surfaces that are higher outside and lower inside;

[0039] The longitudinal displacement adjusting member 2 is placed on the inclined upper surfaces of the two guiding blocks that are higher on the outside and lower on the inside; wherein, the inclined upper surfaces of the two guiding blocks 1 that are higher on the outside and lower on the inside are used to limit the longitudinal displacement adjusting member in the transverse direction.

[0040] Regarding the shape of the upper surface of the guiding block, an inclined upper surface that is higher on the outside and lower on the inside is adopted. In this way, when looking at the upper surfaces of the two guiding blocks from the side, they roughly form an inverted V-shaped structure. The inverted V-shaped structure plays a limiting role on the longitudinal displacement adjusting member in the transverse direction and can prevent the longitudinal displacement adjusting member from detaching from the guiding block in the transverse direction. In this way, the structure of the two guiding blocks has two functions. One function is to provide guidance in the longitudinal direction, and the other function is to limit the longitudinal displacement adjusting member in the transverse direction.

[0041] During implementation, as Figure 2 and Figure 3 shown, the guiding block 1 is a right triangular prism with a right triangle as the bottom surface;

[0042] Among them, one side of the right triangle where a right angle is located is used for fixation, and the sides of the hypotenuses of the right triangles of the two guiding blocks are arranged facing each other as the inclined upper surfaces of the guiding blocks that are higher on the outside and lower on the inside.

[0043] The guiding block is in the form of a right triangular prism with a right triangle as the bottom surface. The shape of the guiding block is relatively regular, which is convenient for production and processing, transportation and installation. When installing the guiding block, as long as the side where the hypotenuse of the right triangle of the guiding block is located is found and the sides of the hypotenuses of the right triangles of the two guiding blocks are arranged facing each other.

[0044] During implementation, as Figure 2 and Figure 3 shown, the two right-angled sides of the right triangle at the bottom of the guiding block 1 have different lengths, and the side where the longer right-angled side of the right triangle is located is used to be fixed to the inner bottom surface of the tunnel;

[0045] In this way, the side where the longer right-angled side of the right triangle is located is used to be fixed to the inner bottom surface of the tunnel, and the fixing area is larger, and a single guiding block is relatively stable; the center of gravity of the longitudinal displacement adjusting member above the guiding block is also lower. When the pipeline moves in the longitudinal direction along with the longitudinal displacement adjusting member, the center of gravity of the pipeline is relatively stable.

[0046] Figure 4 For Figure 2 the schematic diagram of the longitudinal displacement adjusting member shown. Regarding the structure of the longitudinal displacement adjusting member, it is described as follows:

[0047] During implementation, as Figure 2 , Figure 3 and Figure 4As shown, the longitudinal displacement adjusting member 2 includes a longitudinal displacement rod 21, two longitudinal sliding blocks 22 and a longitudinal driving device;

[0048] The two longitudinal sliding blocks 22 are fixedly spaced on the outer peripheral surface of the longitudinal displacement rod 21. The lower surfaces of the two longitudinal sliding blocks 22 are inclined lower surfaces that are higher on the outside and lower on the inside; the inclined lower surfaces of the two longitudinal sliding blocks 22 are respectively placed on the inclined upper surfaces of the two guiding blocks 1;

[0049] The longitudinal driving device is connected to one end of the longitudinal displacement rod, and the longitudinal driving device is used to drive the longitudinal displacement rod to move in the longitudinal direction, driving the longitudinal sliding blocks 22 to move in the longitudinal direction on the upper surface of the guiding block 1.

[0050] The two longitudinal sliding blocks are fixedly spaced on the outer peripheral surface of the longitudinal displacement rod, that is, the two longitudinal sliding blocks and the longitudinal displacement rod are fixed together. The lower surfaces of the two longitudinal sliding blocks are respectively placed on the upper surfaces of the two guiding blocks. This requires that the inclination degrees of the lower surfaces of the two longitudinal sliding blocks are the same as those of the upper surfaces of the two guiding blocks. The inclination directions of the lower surfaces of the longitudinal sliding blocks and the upper surfaces of the two guiding blocks are both higher on the outside and lower on the inside, so that the two guiding blocks block the two longitudinal sliding blocks in the transverse direction, preventing the dislocation of the two longitudinal sliding blocks in the transverse direction. The longitudinal driving device drives the longitudinal displacement rod to move in the longitudinal direction, thereby driving the longitudinal sliding blocks to move in the longitudinal direction on the upper surface of the guiding block, so that the transverse displacement adjusting member and the pipeline can move in the longitudinal direction.

[0051] In implementation, as Figure 2 , Figure 3 and Figure 4 shown, the longitudinal driving device includes:

[0052] A longitudinal fixed seat 231;

[0053] A longitudinal displacement steering device 232, fixed on the longitudinal fixed seat;

[0054] A longitudinal displacement steering wheel 233, the longitudinal displacement steering device is respectively connected to the longitudinal displacement steering wheel and one end of the longitudinal displacement rod;

[0055] Wherein, the longitudinal displacement steering device 232 is used to convert the rotation of the longitudinal displacement steering wheel 233 into translational motion and output it to the longitudinal displacement rod 21 to drive the longitudinal displacement rod 21 to move in the longitudinal direction.

[0056] The longitudinal fixing seat is used to be fixed on the inner bottom surface of the tunnel, thereby realizing the fixation of the longitudinal driving device. Through the longitudinal displacement steering device, the rotation of the longitudinal displacement steering wheel is converted into the movement of the longitudinal displacement rod along the longitudinal direction, thereby driving the sliding block to move along the longitudinal direction on the upper surface of the guiding block.

[0057] In the longitudinal displacement adjusting member, the longitudinal driving device can be fixed on the inner bottom surface of the tunnel through the longitudinal fixing seat, and the longitudinally fixed integrated displacement rod and the two sliding blocks can move along the longitudinal direction under the drive of the longitudinal driving device.

[0058] Figure 5 For Figure 1 the schematic diagram of the lateral displacement adjusting member of the shown transportation limit adjusting system; Figure 6 For Figure 5 the schematic diagram of another angle of the lateral displacement adjusting member.

[0059] Regarding the structure of the lateral displacement adjusting member, it is described as follows:

[0060] As Figure 1 , Figure 5 and Figure 6 shown, in implementation, the lateral displacement adjusting member 3 includes a lateral bearing main body 31. The bottom of the lateral bearing main body is convexly provided with two lateral limiting blocks 311 downward. The two lateral limiting blocks 311 are arranged at intervals in the lateral direction, and the lower surfaces of the two lateral limiting blocks 311 are inclined lower surfaces that are lower outside and higher inside;

[0061] The upper surface of the longitudinal sliding block 22 is an inclined upper surface that is lower inside and higher outside;

[0062] Among them, the inclined lower surfaces of the two lateral limiting blocks 311 are respectively placed on the inclined upper surfaces of the two longitudinal sliding blocks 22 to limit the lateral bearing main body 31 in the lateral direction, and the lateral limiting blocks 311 and the longitudinal sliding blocks 22 are fixed.

[0063] The lower surfaces of the two lateral limiting blocks are respectively placed on the inclined upper surfaces of the two longitudinal sliding blocks. This requires that the inclination degrees of the lower surfaces of the two lateral limiting blocks are the same as those of the upper surfaces of the two longitudinal sliding blocks. The inclination directions of the lower surfaces of the lateral limiting blocks and the upper surfaces of the longitudinal sliding blocks are both in the direction of lower outside and higher inside, so that the two lateral limiting blocks block the two longitudinal sliding blocks in the lateral direction and prevent the dislocation of the two longitudinal sliding blocks in the lateral direction. The fixation of the lateral limiting blocks and the longitudinal sliding blocks fixes the lateral bearing main body and the two longitudinal sliding blocks into one body.

[0064] In implementation, as Figure 5As shown, the upper surface of the horizontal load-bearing main body has a guiding groove 312 in the horizontal direction and two horizontal sliding grooves 313 located on both sides of the guiding groove;

[0065] The horizontal displacement adjusting member further includes two supporting bottom boots 32, a horizontal displacement rod 33 and a horizontal driving device; the supporting bottom boot has a downward guiding protrusion 321, and the supporting bottom boot 32 is fixedly spaced on the outer peripheral surface of the horizontal displacement rod 33 through the guiding protrusion 321;

[0066] Wherein, the supporting bottom boot 32 is used for being fixed to the bottom of the pipeline; pulley wheels 322 are respectively installed at the two bottom sides of the supporting bottom boot 32; the pulley wheels 322 are placed on the horizontal sliding grooves 313, and the guiding protrusion 321 is located in the guiding groove 312 and keeps a gap with the inner bottom of the guiding groove;

[0067] The horizontal driving device is fixedly connected to the horizontal displacement rod, and the horizontal driving device is used for driving the horizontal displacement rod to move in the horizontal direction, driving the guiding protrusion 312 to move in the horizontal direction in the guiding groove 312, driving the pulley wheels 322 to move in the horizontal direction in the horizontal sliding grooves 313, so as to drive the supporting bottom boot to move in the horizontal direction on the horizontal load-bearing main body.

[0068] In this way, the horizontal driving device and the horizontal load-bearing main body are fixed, and the two supporting bottom boots and the horizontal displacement rod are fixed as a whole. Driven by the horizontal driving device, the two supporting bottom boots and the horizontal displacement rod fixed as a whole can move in the horizontal direction along the guiding groove.

[0069] During implementation, as Figure 2 , Figure 3 and Figure 4 shown, the longitudinal sliding block 22 is a straight quadrangular prism with an isosceles trapezoid bottom surface;

[0070] Wherein, the sides where the longer bottom sides of the isosceles trapezoids of the two longitudinal sliding blocks 22 are located face each other, and the sides where the waists of the isosceles trapezoids of the longitudinal sliding blocks are located are respectively used as the lower surface and the upper surface of the longitudinal sliding block.

[0071] The longitudinal sliding block adopts the form of a straight quadrangular prism with an isosceles trapezoid bottom surface, and the shape of the longitudinal sliding block is relatively regular, which is convenient for production and processing, and also convenient for transportation and installation.

[0072] During implementation, as Figure 5 and Figure 6 shown, the upper surfaces of the two supporting bottom boots 32 are inclined upper surfaces that are higher outside and lower inside to limit the pipeline in the horizontal direction.

[0073] The two supporting bottom boots realize the support of the pipeline and the limitation in the horizontal direction.

[0074] During implementation, as Figure 5 and Figure 6 shown, the lateral drive device includes:

[0075] A lateral displacement steering wheel 341 and a lateral displacement steering gear 342; the lateral displacement steering gear 342 is fixed on the lateral bearing body 31, and the lateral displacement steering gear 342 is respectively connected to one end of the lateral displacement steering wheel 342 and the lateral displacement rod 33;

[0076] Wherein, the lateral displacement steering gear 342 is used to convert the rotation of the lateral displacement steering wheel 341 into translational motion and output it to the lateral displacement rod 33, driving the lateral displacement rod 33 and the support sole 32 to move along the lateral direction; the upper surface of the support sole is used to carry the pipeline.

[0077] Through the lateral displacement steering gear, the rotation of the lateral displacement steering wheel is converted into the movement of the lateral displacement rod along the lateral direction, driving the lateral displacement rod and the support sole to move along the lateral direction, thereby driving the pipeline to move along the lateral direction.

[0078] During implementation, there are multiple groups of limit adjustment components, and each group of limit adjustment components includes two or three or four of the limit adjustment components; wherein, the limit adjustment component includes two of the guide blocks, one longitudinal displacement adjustment and one lateral displacement adjustment member;

[0079] One section of the pipeline is matched with one group of limit adjustment components, and the longitudinal displacement steering wheels of the same group of limit adjustment components rotate synchronously, and the lateral displacement steering wheels of the same group of limit adjustment components rotate synchronously.

[0080] In this way, when each section of the pipeline moves, the longitudinal displacement steering wheels of a group of limit adjustment components that cooperate with it rotate synchronously, and the lateral displacement steering wheels rotate synchronously, realizing the movement of a single section of the pipeline in the longitudinal direction and the lateral direction.

[0081] Specifically, the support sole is made of section steel and steel plates, and is fixedly connected to the bottom of the pipeline, and its connection method is by bolts or welding.

[0082] Specifically, the lateral bearing body is made of section steel and steel plates, the shape of the chute part should match the shape of the clamping block of the support sole, and the lateral displacement rod is made of steel.

[0083] Specifically, the lateral limit block and the longitudinal sliding block are fixedly connected, and their connection method is by bolts or welding.

[0084] Specifically, the longitudinal sliding block is made of steel, and the longitudinal displacement rod is made of steel.

[0085] Specifically, the guiding block is made of concrete or steel. The bottom of the guiding block is connected to the secondary lining structure at the bottom of the tunnel, and the connection method is by planting steel bars or bolts.

[0086] Specifically, the top fixing bracket is made of section steel and steel plates, and the top fixing bracket should be connected to the second-layer structure at the top of the tunnel, and the connection method is by embedding, bolts or welding. The slider hoisting assembly is made of steel plates and should be connected to the pipeline, and the connection method is by bolts or welding.

[0087] It should be noted that the moving range of the sliding block along the longitudinal direction on the upper surface of the guiding block is limited by the height of the straight triangular prism with a right-angled triangle at the bottom surface of the guiding block itself. Therefore, the moving range along the longitudinal direction is restricted and is only suitable for fine-tuning in the transverse direction. The moving range of the supporting bottom shoe along the transverse direction is limited by the distance between the chute and the supporting bottom shoe. Therefore, the moving range along the transverse direction is also restricted. Therefore, when setting the position of the guiding block, it is necessary to consider the target position of the pipeline in the tunnel so that the target position of the pipeline is within the moving range of the supporting bottom shoe along the transverse direction.

[0088] Embodiment 2

[0089] The transportation limit adjustment system for erecting pipelines in the embodiment of the present application further has the following features on the basis of Embodiment 1.

[0090] Figure 7 For Figure 1 the schematic diagram of the hoisting track structure of the transportation limit adjustment system shown. During implementation, as Figure 1 and Figure 7 shown, the transportation limit adjustment system further includes a hoisting track structure; the hoisting track structure includes:

[0091] A top fixing bracket 41 for fixing on the inner top surface of the tunnel, and the center line of the top fixing bracket 41 coincides with the center line of the tunnel;

[0092] Two guide rails 42, and the two guide rails 42 are fixedly spaced in the transverse direction at the bottom of the top fixing bracket 41. The length of the guide rails 42 is the same as the length of the tunnel, and the two guide rails 42 are symmetrically arranged with respect to the center line of the top fixing bracket;

[0093] A balance beam 43, which is connected between the two guide rails 42 and the balance beam 43 can move along the guide rails in the longitudinal direction; a slider hoisting assembly is installed on the side surface of the balance beam 43; the slider hoisting assembly is used for detachably connecting with the pipeline, and the slider hoisting assembly can move along the balance beam in the transverse direction and can be locked with the balance beam.

[0094] The top fixing bracket is fixed to the inner top surface of the tunnel, and the center line of the top fixing bracket coincides with the center line of the tunnel; at this time, the two guide rails are symmetrically arranged with respect to the center line of the tunnel. When it is necessary to transport the pipeline from outside the tunnel to inside the tunnel, the slider hoisting assembly is fixed and locked at the middle position of the crossbeam, and is fixed through the slider hoisting assembly and the pipeline. At this time, the pipeline is located at the entrance of the tunnel and at the center of the tunnel. The crossbeam moves along the guide rail in the longitudinal direction until it moves to the preset position of the pipeline. At this time, the pipeline is located at the center of the tunnel. Since the pipeline is sometimes installed deviating from the center line position of the tunnel, at this time, it is necessary to move the pipeline in the transverse direction. The way to achieve this is that the slider hoisting assembly drives the pipeline to move in the transverse direction along the crossbeam; until it is located above the support bottom shoe, and the pipeline is placed on the support bottom shoe.

[0095] After that, more precise positioning of the pipeline is carried out, and precise adjustment in the longitudinal direction and the transverse direction is achieved through the longitudinal displacement adjusting member and the transverse displacement adjusting member.

[0096] The transportation limit adjustment system for erecting pipelines in the embodiments of the present application adopts a method of separately arranging the hoisting track structure and the limit adjustment assembly. The hoisting track structure is arranged on the inner top surface of the tunnel, which improves the utilization of the upper space of the tunnel, reserves the inner bottom surface space of the tunnel, and also reduces the interference with other operations in the tunnel; the limit adjustment assembly is arranged on the inner bottom surface of the tunnel, so that the structure arranged on the inner bottom surface of the tunnel is relatively less. Since the space in the tunnel is relatively small and various operations need to be carried out, and equipment required for various operations is set up, therefore, reducing the structure arranged on the inner bottom surface of the tunnel can greatly reduce the construction complexity and difficulty. It can realize the rapid splicing of pipelines in the tunnel and underground space, effectively shortening the construction period. At the same time, it is applicable to tunnels with different cross-sectional shapes and can be widely applied to mountain tunnels and urban underground spaces.
