DETAILED DESCRIPTION

[0030] See also Figure 1-Figure 11In an embodiment of the present invention, a gas pipeline construction device includes a base plate 1. Preferably, a first fixing plate 2 is fixedly provided at one end of the top of the base plate 1, and a second fixing plate 12 is fixedly provided at the other end of the top of the base plate 1. A placement hole 3 is horizontally provided at the center of the first fixing plate 2 and the second fixing plate 12, and an extension plate is provided on the side of the first fixing plate 2 and the second fixing plate 12 that are relatively far away. The extension plate facilitates the placement of the gas pipeline. A clamping component is provided at the upper end of the placement hole 3, and an auxiliary component is provided on the side of the first fixing plate 2 close to the second fixing plate 12. The auxiliary component is slidably connected to the top of the base plate 1. In the initial state, the clamping component in the placement hole 3 is at the top position in the placement hole 3. At this time, the two groups of gas pipelines that need to be welded are sequentially It is placed in the placement holes 3 on the first fixed plate 2 and the second fixed plate 12, and then pushed in the direction of the auxiliary component, so that under the action of the auxiliary component, the end of the gas pipeline close to the auxiliary component is in a horizontal state, avoiding the possible tilt of the gas pipeline, which causes the two sets of gas pipelines to be uneven when docking, resulting in low welding quality or unavailable welding; when the auxiliary component moves in the direction of the second fixed plate 12, the auxiliary component drives the clamping component in the first fixed plate 2 to move relative to the bottom plate 1 to clamp the gas pipeline in the first fixed plate 2; when the auxiliary component moves to both sides of the bottom plate 1, the auxiliary component drives the clamping component in the second fixed plate 12 to move toward the bottom plate 1 to clamp the gas pipeline in the second fixed plate 12.

[0031] Further, preferably, the clamping assembly includes a clamping plate 8; the clamping plate 8 is symmetrically arranged along the center of the top of the placement hole 3, the end of the clamping plate 8 away from the bottom plate 1 is rotatably connected to the screw rod 7, the screw rod 7 is rotatably connected to the inner wall of the first fixed plate 2, and the side walls of the top inner ends of the first fixed plate 2 and the second fixed plate 12 are provided with a transmission cavity 14 connected to the placement hole 3, the end of the screw rod 7 away from the clamping plate 8 extends into the transmission cavity 14, the clamping plate 8 is an arc-shaped structure, and the screw rod 7 is diagonally arranged at the top of the placement hole 3, and the outer side of the screw rod 7 The side wall and the side wall of the first fixed plate 2 are rotationally connected via a threaded structure. In the initial state, the screw rod 7 is contracted at its lowest point in the transmission chamber 14, thereby making the clamping plate 8 as close to the transmission chamber 14 as possible. When the screw rod 7 rotates, the screw rod 7 cooperates with the threaded structure of the first fixed plate 2 to move away from the transmission chamber 14. The movement of the screw rod 7 causes the clamping plate 8 to move away from the transmission chamber 14, thereby making the clamping plate 8 contact and clamp the gas pipeline placed in the placement hole 3.

[0032] Preferably, a telescopic rod is fixedly provided between the side of the clamping plate 8 close to the transmission cavity 14 and the placement hole 3. The telescopic rod enables the clamping plate 8 to remain in a fixed state when the screw 7 rotates, thereby preventing the clamping plate 8 from rotating and causing the problem of being unable to fit with the periphery of the gas pipeline.

[0033] See also Figure 2 , Figure 5 , Figure 6 Preferably, one end of the screw rod 7 away from the clamping plate 8 is fixedly connected to a driven gear 20, and one side of the driven gear 20 is transmission-matched with a driving gear 16, and one end of the driving gear 16 away from the clamping plate 8 is fixedly connected to a first wire drum 23, and a first pull rope 21 is wound around the first wire drum 23. The end of the first pull rope 21 away from the first wire drum 23 slides through the side wall of the first fixed plate 2 and is fixedly connected to the auxiliary component, and a base 22 is rotatably provided at the bottom end of the driving gear 16, and a torsion spring is provided between the base 22 and the driving gear 16. Through the provision of the torsion spring, the driving gear 16 can automatically rotate and reset when there is no force, and the base 22 is elastically connected to the side of the transmission cavity 14 close to the bottom plate 1 through a spring. When in use, in the initial state, the auxiliary component is in contact with the first fixed plate 2. When the gas pipeline is inserted through the placement hole 3 on the first fixed plate 2 and the gas pipeline is in contact with the auxiliary component, the auxiliary component can keep the gas pipeline horizontal, and push the gas pipeline toward the direction of the second fixed plate 12 by hand, so that the auxiliary The auxiliary component moves toward the second fixed plate 12, and then the auxiliary component pulls the first pull rope 21 to spread out on the first wire drum 23, so that the first wire drum 23 rotates to drive the driving gear 16 to rotate, and the driving gear 16 rotates to drive the driven gear 20 to rotate, and the driven gear 20 rotates to drive the screw rod 7 to rotate, and the screw rod 7 rotates to cooperate with the side wall thread of the first fixed plate 2 to realize the movement of the screw rod 7 toward the gas pipeline, and then push the clamping plate 8 to contact the gas pipeline and clamp the gas pipeline. Then, another group of gas pipelines is inserted through the placement hole 3 in the second fixed plate 12 and pushed in the direction of the auxiliary component, so that the other group of gas pipelines contacts and cooperates with the auxiliary component, and the auxiliary component is moved to both sides of the bottom plate 1. At this time, the movement of the auxiliary component causes the clamping component in the second fixed plate 12 to move toward the gas pipeline of the second fixed plate 12 and clamp it to position it. Through the cooperation of the auxiliary component and the clamping component, the opposite ends of the two groups of gas pipelines are kept in a horizontal corresponding state, thereby facilitating their welding.

[0034] See also Figure 2 , Figure 5Preferably, a square groove is provided on one side of the clamping plate 8 away from the screw rod 7, a slider 9 is slidably connected in the square groove, the clamping plate 8 and the screw rod 7 are hollow structures, and one end of the screw rod 7 away from the clamping plate 8 is rotatably connected to the first hose 15, the square groove and the first hose 15 are connected, the end of the first hose 15 away from the screw rod 7 passes through the side wall of the first fixed plate 2 and is connected to the airbag 24, the top of the airbag 24 is fixedly provided with a connecting rod 17, the bottom end of the connecting rod 17 passes through the airbag 24 and is fixedly connected to a trigger block 171, the airbag 24 slides with the inner wall of the first fixed plate 2 Dynamic connection, the trigger block 171 slides and fits with the transmission chamber 14, and an arc plate is fixedly provided at one end of the base 22 away from the screw rod 7, and the arc plate slides and cooperates with the end of the trigger block 171; the airbag 24 is an elastic telescopic structure. When gas is input into the airbag 24, the airbag 24 expands upward, and the bottom of the airbag 24 is fixedly connected to the inner wall of the first fixed plate 2, and the airbag 24 is a circular ring structure. When the airbag 24 no longer transports gas into the airbag 24, the airbag 24 can elastically contract and reset, and the bottom of one end of the trigger block 171 close to the arc plate is provided with an inclined surface facing the clamping plate 8.

[0035] When in use, in the initial state, the slider 9 protrudes from the side wall of the clamping plate 8, the airbag 24 shrinks, the trigger block 171 protrudes from the placement hole 3, the end of the trigger block 171 fits with the end of the arc plate, and the driving gear 16 meshes with the driven gear 20; when the auxiliary component moves toward the direction of the second fixed plate 12, the auxiliary component rotates the first wire drum 23 through the first pull rope 21, and the rotation of the first wire drum 23 drives the driving gear 16 to rotate, and the rotation of the driving gear 16 drives the driven gear 20 to rotate, and the rotation of the driven gear 20 drives the screw rod 7 to rotate, and the screw rod 7 moves toward the bottom plate 1 under the cooperation of the first fixed plate 2. In the process of the screw rod 7 driving the driven gear 20 to move, the driven gear 20 and the driving gear 16 always remain meshed, and when the clamping plate 8 moves so that the slider 9 contacts the gas pipeline and is pushed to shrink relatively to the clamping plate 8, the slider 9 squeezes the gas in the square groove through the clamping plate 8, the screw rod 7 and the first hose 1 5 is transported into the airbag 24, so that the airbag 24 expands upward, thereby causing the connecting rod 17 to move upward. The movement of the connecting rod 17 causes the trigger block 171 to move upward and separate from the arc plate. Subsequently, the base 22 moves in the direction of the trigger block 171 under the action of the corresponding spring, so that the driving gear 16 is separated from the driven gear 20. It should be noted that when one group of sliders 9 is retracted in the square groove, the corresponding gas transported into the airbag 24 will push the trigger block 171 to move upward, but the distance moved by the trigger block 171 is the position of the end of the arc plate corresponding to the inclined surface on it. At this time, the driving gear 16 is still meshed with the driven gear 20. When the other group of sliders 9 is retracted in the square groove, the trigger block 171 will separate from the arc plate. Only when the two groups of sliders 9 are retracted in the square groove, the trigger block 171 will separate from the arc plate, so that the two groups of driving gears 16 are synchronously separated from the driven gear 20.

[0036] See also Figure 5 Preferably, a ball 28 is rotatably provided on one side of the slider 9 and the clamping plate 8 away from the screw rod 7, and a plurality of groups of ball 28 are arranged in an array on the clamping plate 8 and the slider 9, and one end of the ball 28 away from the screw rod 7 protrudes out of the side walls of the clamping plate 8 and the slider 9, so that when the clamping plate 8 moves toward the gas pipeline and clamps it, the slider 9 contacts the gas pipeline, so that after the clamping plate 8 clamps the pipeline, it can also push the pipeline toward the auxiliary component, so that the clamping component can clamp gas pipelines of different sizes, and after clamping, it can also push the gas pipeline to move, so that the end of the gas pipeline moves to the center position of the first fixed plate 2 and the second fixed plate 12, thereby facilitating the welding operation of the two groups of gas pipelines.

[0037] See also Figure 1-Figure 4 , Figure 7-Figure 11Preferably, the auxiliary component includes a horizontal plate 5; a mounting groove 10 is provided at the top of the bottom plate 1 and on one side close to the first fixed plate 2, and through grooves passing through the top of the bottom plate 1 are provided on both sides of the mounting groove 10, a slide plate 13 is slidably provided in the mounting groove 10, the horizontal plate 5 is slidably provided at one end of the slide plate 13 close to the second fixed plate 12, and the horizontal plate 5 is symmetrically provided along the center of the slide plate 13, the horizontal plate 5 is slidably fitted with the side wall of the first fixed plate 2, an extension groove 11 connected to the mounting groove 10 is provided at the center of the bottom plate 1, the end of the first pull rope 21 on the first fixed plate 2 away from the first wire drum 23 is fixedly connected to the end of the slide plate 13 away from the second fixed plate 12; the top height of the horizontal plate 5 is flush with the center of the placement hole 3, the slide plate 13 and the mounting groove 10 are elastically connected by a spring, the extension groove 11 and the mounting groove 10 are perpendicular to each other, and the horizontal plate 5 is slidably fitted with the extension groove 11.

[0038] When in use, in the initial state, the slide plate 13 is located close to the first fixed plate 2 and the horizontal plate 5 is in contact with the side wall of the first fixed plate 2. When welding the gas pipeline, a group of gas pipelines are inserted through the placement holes 3 on the first fixed plate 2 and then pushed in the direction of the second fixed plate 12, so that the gas pipeline will not tilt under the restriction of the horizontal plate 5, and the gas pipeline will be forced to move, which will push the horizontal plate 5 to move in the direction of the second fixed plate 12, thereby causing the slide plate 13 to move in the direction of the second fixed plate 12. The movement of the slide plate 13 will pull the first pull rope 21, so that the first wire drum 23 will spread out, allowing the first wire drum 23 to rotate, so that the driving clamping assembly can clamp the gas pipeline. When the two sets of sliders 9 move and shrink in the square groove, the driving gear 16 is separated from the driven gear 20. At this time, under the action of the ball 28, the gas pipeline can be pushed to move in the direction of the extension groove 11. When the horizontal plate 5 moves to the position corresponding to the extension groove 11, the gas pipeline can no longer be pushed to move. Then another set of gas pipelines is inserted into the placement hole 3 of the second fixed plate 12 and pushed in the direction of the horizontal plate 5. When the other set of gas pipelines is in contact with the horizontal plate 5, the horizontal plate 5 will slide on the slide plate 13 into the extension groove 11. The sliding of the horizontal plate 5 will cause the clamping assembly in the second fixed plate 12 to move toward the gas pipeline and clamp the gas pipeline, and then welding can be carried out.

[0039] Furthermore, preferably, a tooth plate 27 is fixedly provided at the bottom of the horizontal plate 5, and the sides on which the teeth are provided on the two groups of tooth plates 27 are opposite to each other, and a synchronous gear is transmission-connected between the two groups of tooth plates 27, and the synchronous gear is arranged at the center of the tooth plate 27 and is rotationally connected to the skateboard 13, so that when one group of tooth plates 27 moves out of the side wall of the skateboard 13, the other group of tooth plates 27 is synchronously moved out of the side wall of the skateboard 13 through the synchronous gear, thereby causing the two groups of horizontal plates 5 to synchronously move away from the skateboard 13, and the two groups of horizontal plates 5 are respectively arranged on both sides of the end of the skateboard 13, and the tooth plates 27 are slidably adapted to the extension groove 11. When the end of the skateboard 13 moves to correspond to the extension groove 11, the tooth plate 27 corresponds to the extension groove 11, that is, the tooth plate 27 can slide into the extension groove 11, thereby causing the horizontal plate 5 to move into the extension groove 11.

[0040] See also Figure 1-Figure 2 Preferably, an air cavity connected to the placement hole 3 is provided in the first fixed plate 2 near the bottom end of the placement hole 3, an arc block 4 is slidably provided in the air cavity, a spring is provided between the arc block 4 and the air cavity, and a second hose 18 is provided between the bottom of the air cavity and the slide plate 13. When the gas pipeline is placed in the placement hole 3 on the first fixed plate 2, the gas pipeline will push the arc block 4 downward and shrink it in the air cavity, thereby allowing the gas in the air cavity to be transported into the second hose 18. When the gas pipeline is removed from the placement hole 3, the arc block 4 can be moved and reset under the action of the spring.

[0041] See also Figure 1-Figure 2 , Fig. 9 A gas storage tank 30 is provided in the slide plate 13, and the end of the second hose 18 away from the arc block 4 is connected to the gas storage tank 30, and the connection between the second hose 18 and the gas storage tank 30 is arranged on a side of the gas storage tank 30 close to the tooth plate 27, and a piston plate is elastically provided in the gas storage tank 30, and the piston plate is arranged on the side of the connection between the gas storage tank 30 and the second hose 18 away from the tooth plate 27, and a group of tooth plates 27 near the gas storage tank 30 are fixedly provided with a cross plate, and a telescopic tube 29 is fixedly provided between the cross plate and the inner wall of the mounting groove 10, and the end of the telescopic tube 29 away from the cross plate is connected to the gas storage tank 30, and a spring is fixedly provided between the end of the cross plate away from the telescopic tube 29 and the mounting groove 10. When a group of gas pipelines are placed on the arc block 4, the arc block 4 moves downward, which will fill the gas storage tank 30 with gas, so that when the horizontal plate 5 moves to the extension groove 11, it can move into the extension groove 11 and separate from the end of a group of gas pipelines, thereby facilitating subsequent docking and welding work.

[0042] During specific use, in the initial state, the piston plate is in a position close to the second hose 18, and the two groups of tooth plates 27 are both in the slide plate 13 under the action of the cross plate and the spring, so that the horizontal plate 5 is in the two sides of one end of the slide plate 13, and the telescopic tube 29 is in a retracted state; when the arc block 4 moves downward and shrinks in the air cavity, the gas therein is transported to the gas storage tank 30 through the second hose 18, and at this time, when the end of the slide plate 13 has not moved to the position of the extension groove 11, that is, the tooth plate 27 and the horizontal plate 5 do not correspond to the extension groove 11, the gas will push the piston plate to move in the direction away from the tooth plate 27, and when the horizontal plate 5 and the tooth plate 27 move to the position corresponding to the extension groove 11, the piston plate elastically resets, so that the gas in the gas storage tank 30 enters the telescopic tube 29, causing the telescopic tube 29 to expand and expand, thereby pushing one group of tooth plates 27 to move into the extension groove 11 through the cross plate, and through the action of the synchronous gear, the other group of tooth plates 27 will also move synchronously to the corresponding extension groove 11.

[0043] See also Figure 7-Figure 8 Preferably, the side of the horizontal plate 5 close to the second fixed plate 12 is elastically connected with an auxiliary plate 6, and the top side wall of the mounting groove 10 is provided with a notch 26 for the auxiliary plate 6 to slide with, and the two opposite sides are provided with inclined surfaces, so that when in use, the auxiliary plate 6 protrudes from the horizontal plate 5 and cooperates with the notch 26, so that after one group of gas pipelines is clamped, when the other group of gas pipelines is not placed, the horizontal plate 5 continues to block one group of gas pipelines to prevent them from moving and causing deviations in subsequent docking. When the other group of gas pipelines is placed, the other group of gas pipelines pushes the auxiliary plate 6 to separate the auxiliary plate 6 from the notch 26, so that the horizontal plate 5 moves into the extension groove 11, and then pushes the pipeline to make the two groups of pipelines correspond to each other, ensuring that the two groups of pipelines are horizontally aligned, and the inclined surface can make the auxiliary plate 6 and the notch 26 cooperate again after the horizontal plate 5 moves and resets, ready for the next use.

[0044] In the initial state, the auxiliary plate 6 corresponds to the notch 26, and the relative positions of the horizontal plate 5 and the slide plate 13 are limited. At this time, even if the horizontal plate 5 moves to the position corresponding to the extension groove 11, the gas in the gas storage tank 30 will not be transported to the telescopic tube 29 to expand it. When another set of gas pipelines are inserted into the placement hole 3 on the second fixed plate 12 and pushed to contact the auxiliary plate 6, and the auxiliary plate 6 is pushed to move toward the horizontal plate 5 to fit, the bottom of the auxiliary plate 6 is separated from the notch 26, and then the gas in the gas storage tank 30 is transported to the telescopic tube 29 to expand it, so that the tooth plate 27 and the horizontal plate 5 move into the extension groove 11, and then the horizontal plate 5 is separated from the pipeline, so as not to affect the docking work, and through the cooperation of the horizontal plate 5 and the auxiliary plate 6, the two sets of pipelines are kept horizontally corresponding when docking, and the problem of one set of pipelines being tilted will not occur.

[0045] See also Figure 9-11A transmission disc 31 is rotatably arranged in the top side wall of the bottom plate 1, and a second wire drum 25 is transmission-engaged on the side of the transmission disc 31 away from the first fixed plate 2. The first pull rope 21 corresponding to the second fixed plate 12 is fixedly connected to the second wire drum 25, and a third wire drum is fixedly arranged at the top center of the transmission disc 31, and a second pull rope is wound on the third wire drum. A push plate 19 is fixedly arranged on the end of the second pull rope away from the third wire drum, and the push plate 19 is slidably connected to the inner wall of the bottom plate 1, and the end of the push plate 19 away from the second fixed plate 12 slides into the extension groove 11. The transmission disc 31 and the second wire drum 25 are both arranged at the top center of the bottom plate 1; when in use, when the tooth plate 27 moves into the extension groove 11, the tooth plate 27 moves into the extension groove 11. The plate 27 pushes the pushing plate 19 to move in the direction away from the transmission disk 31. The pushing plate 19 moves to pull the second pull rope so that it spreads out on the third wire drum, causing the transmission disk 31 to rotate. The rotation of the transmission disk 31 drives the second wire drum 25 to rotate. The rotation of the second wire drum 25 reels the corresponding first pull rope 21 on the second fixed plate 12. Then, through the cooperation of the first wire drum 23, the driving gear 16, and the driven gear 20, the screw rod 7 on the second fixed plate 12 rotates and extends into the placement hole 3, and the clamping work of the other group of gas pipelines is completed through the clamping plate 8. When the clamping work is completed, the other group of gas pipelines are pushed to move toward one group of gas pipelines to achieve alignment of the ends of the two, thereby facilitating welding work.

[0046] See also Figure 1-Figure 11 Preferably, a vent (not shown in the figure) is provided on the side wall of the first fixed plate 2, the vent is connected to the air cavity and the first hose 15, and a valve is provided in the vent. In the initial state, the valve is in a closed state, and the arc block 4 extends into the placement hole 3, so that after the arc block 4 moves downward, the gas in the air cavity can be transported to the air storage tank 30. When the welding work is completed, the valve is opened to allow the gas in the telescopic tube 29 to be discharged through the air storage tank 30, the second hose 18, and the air cavity, as well as the gas in the first hose 15 and the airbag 24. Subsequently, after the tooth plate 27 moves and resets, the first pull rope 21 is no longer subjected to force, and the trigger block 171 moves and resets to make the base 22 move and reset, and at the same time, the driving gear 16 rotates and resets. At this time, the driving gear 16 rotates and drives the driven gear 20 to rotate and reset, thereby causing the screw rod 7 to rotate and reset, so that the clamping plate 8 and the pipeline are separated, and finally the slide plate 13 moves and resets. After the pipeline is removed, the arc block 4, the slider 9, etc. are reset and the valve can be closed for next use.
