Description

Technical Field

[0001] This invention relates to the field of municipal engineering technology, specifically to a support device that prevents pipes from being scratched and reduces construction resistance. Background Technology

[0002] PE is the abbreviation for Polyethylene (Polyethylene of raised temperature resistance). Generally, PE pipes are used for water supply systems at temperatures below 40℃ and cannot be used for hot water delivery. PE pipes are made from a highly crystalline, non-polar thermoplastic resin. In its natural state, HDPE is milky white and, in thin sections, somewhat translucent.

[0003] When welding or constructing PE pipes, they need to be moved. For larger pipes, a crane is usually used to lift them to the designated location, and then workers manually drag them to the location where construction or welding is needed. For pipes that do not require a crane, workers directly pull the pipes. When moving PE pipes in this way, the pipes will rub and scrape against the ground, causing damage to the pipes, rendering them unusable, or reducing their performance. This is especially true for longer PE pipes, which experience greater friction when pulled. The greater the resistance, the more force is required to pull, and the greater the pulling force, the greater the friction on the pipes.

[0004] Based on this, the present invention designs a support device to prevent pipe scratches and reduce construction resistance, so as to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a support device that prevents pipe scratches and reduces construction resistance, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support device for preventing pipe scratches and reducing construction resistance, comprising a base plate, two support plates fixedly connected to the top of the base plate, a cylinder fixedly connected to the top of the base plate, the cylinder being located between the two support plates, a connector fixedly connected to the top of the cylinder, two support rods rotatably connected to the connector, each of the two support rods being rotatably connected to a roller, a limit rod fixedly connected to the bottom of each of the two support rods, a limit block slidably connected to each of the two limit rods, and the two limit blocks being rotatably connected to the two support rods respectively.

[0007] As a further embodiment of the present invention, limit groups are provided on both sides of the two support plates;

[0008] The limiting assembly includes a horizontal plate and a top plate; the horizontal plate is slidably connected to a support plate; the horizontal plate is fixedly connected to a first spring for its reset; the top plate is fixedly connected to a connecting member; the top plate is located below the horizontal plate and is used to lift the horizontal plate; the horizontal plate is slidably connected to a connecting rod; the connecting rod is fixedly connected to a fixing rod; the top and bottom ends of the fixing rod are both fixedly connected to arc-shaped rods; the side walls of the two arc-shaped rods are slidably connected to support members; the two support members are each provided with a blocking rod; the ends of the blocking rods are rotatably connected to ball bearings; the two support members are slidably connected to lifting rods; the two lifting rods are threadedly connected to a bidirectional lead screw; the bottom end of the bidirectional lead screw is fixedly connected to a round rod; the round rod is rotatably connected to the connecting rod; the bottom end of the round rod is fixedly connected to a gear; the gear meshes with a rack rod; the rack rod is fixedly connected to the top of the horizontal plate; a rotating shaft is fixedly connected to the side wall of the connecting rod; a resisting rod is provided below the rotating shaft; the resisting rod is fixedly connected to the side wall of the support plate; the resisting rod is inclined.

[0009] As a further embodiment of the present invention, the barrier bar is slidably connected to the support member; the barrier bar is fixedly connected to a second spring for its reset.

[0010] As a further embodiment of the present invention, the fixed rod is rotatably connected to a roller, and the roller is made of rubber.

[0011] As a further embodiment of the present invention, each side wall of the support member is fixedly connected with a sliding rod, and the support member is slidably connected to the arc-shaped rod through the sliding rod.

[0012] As a further embodiment of the present invention, the limiting rod is T-shaped.

[0013] As a further embodiment of the present invention, the support plate is provided with a limiting groove, and the horizontal plate is slidably connected to the limiting groove.

[0014] As a further embodiment of the present invention, the roller is made of rubber.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The pipes to be dragged are supported by rollers. The pipes are in contact with the rollers, and the pipes drive the rollers to rotate during the dragging process. This reduces the resistance generated by dragging the pipes during the welding process, which facilitates construction. In addition, the pipes are at a certain distance from the ground, which provides some protection for the pipes and prevents foreign objects from scratching them.

[0017] 2. When the cylinder extends or retracts, the distance between the two rollers gradually decreases, the included angle between the two rollers gradually decreases, and the two rollers form a V-shaped groove. The V-shaped groove can accommodate and limit the pipe, preventing the pipe from rolling to the ground during dragging. It can also prevent the pipe from falling off after slight collisions and shaking during dragging. By controlling the extension and retraction of the cylinder, the rollers can be controlled to support pipes of different sizes, thus improving the applicability.

[0018] 3. The limiting group can limit pipes of different sizes on both sides to prevent them from falling to the ground due to large external impacts when being dragged above the roller, thus ensuring the support effect of the pipes. Attached Figure Description

[0029] Please see Figure 1-8 This invention provides a technical solution: a support device for preventing pipe scratches and reducing construction resistance, comprising a base plate 1, two support plates 2 fixedly connected to the top of the base plate 1, a cylinder 3 fixedly connected to the top of the base plate 1, the cylinder 3 being located between the two support plates 2, a connector 4 fixedly connected to the top of the cylinder 3, two support rods 5 rotatably connected to the connector 4, rollers 6 rotatably connected to the two support rods 5, limit rods 7 fixedly connected to the bottom of the two support rods 5, limit blocks 8 slidably connected to the two limit rods 7, and the two limit blocks 8 rotatably connected to the two support rods 5 respectively.

[0030] When the above solution is put into practical use, several support devices are first placed at certain intervals on the ground. Then, the pipe is placed above the roller 6. The base plate 1 and the support plate 2 can provide support for the roller 6. The roller 6 supports the pipe that needs to be dragged. The pipe is in contact with the roller 6. During the dragging process, the pipe drives the roller 6 to rotate, which reduces the resistance generated by dragging the pipe during the welding process, facilitates construction, and has a certain distance from the ground, which has a certain protective effect on the pipe and prevents foreign objects from scratching the pipe.

[0031] When cylinder 3 is not extending or retracting, the angle between the two rollers 6 is relatively large, allowing them to support larger pipes. If the pipe diameter is small, cylinder 3 needs to be activated. The extension or retraction of cylinder 3 pulls the bottom ends of the two support rods 5 via connector 4. The pull of connector 4 causes the limiting rod 7 to slide within the limiting block 8, which rotates on the inner wall of support plate 2. At this time, the angle between the two rollers 6 gradually decreases, forming a V-shaped groove. This V-shaped groove accommodates and limits the pipe, preventing it from rolling onto the ground during dragging and also preventing it from being dragged too far. It can fall after slight collisions and shaking during the process. As long as the diameter of the pipe does not exceed Y (Y is the distance between the tops of the two rollers 6), the horizontal height of the center point of the pipe is below the tops of the two rollers 6. The V-shaped groove formed by the two rollers 6 can well accommodate and support the pipe. Since the distance between the two rollers 6 gradually decreases when the cylinder 3 extends and retracts, it can support and accommodate pipes of different sizes, thereby improving the applicability of the entire support device. It has a simple structure, is green and environmentally friendly, can be reused, and is easy to construct. The use of channel steel as the base improves the rigidity and stability of the support, and it is not easy to deform or tip over during use.

[0032] As a further embodiment of the present invention, limit groups are provided on both sides of the two support plates 2;

[0033] The limiting assembly includes a horizontal plate 9 and a top plate 10; the horizontal plate 9 is slidably connected to a support plate 2; the horizontal plate 9 is fixedly connected to a first spring 11 for its reset; the top plate 10 is fixedly connected to a connecting member 4; the top plate 10 is located below the horizontal plate 9 and is used to lift the horizontal plate 9; the horizontal plate 9 is slidably connected to a connecting rod 12; the connecting rod 12 is fixedly connected to a fixing rod 13; the top and bottom ends of the fixing rod 13 are both fixedly connected to arc-shaped rods 14; the side walls of the two arc-shaped rods 14 are slidably connected to support members 15; the two support members 15 are each provided with a blocking rod 16; the ends of the blocking rods 16 are each... A ball bearing 25 is rotatably connected. Both support members 15 are slidably connected to lifting rods 17. The two lifting rods 17 are threadedly connected to a bidirectional lead screw 18. A round rod 19 is fixedly connected to the bottom end of the bidirectional lead screw 18. The round rod 19 is rotatably connected to the connecting rod 12. A gear 20 is fixedly connected to the bottom end of the round rod 19. The gear 20 meshes with a rack rod 21. The rack rod 21 is fixedly connected to the top of the horizontal plate 9. A rotating shaft 22 is fixedly connected to the side wall of the connecting rod 12. A resisting rod 23 is provided below the rotating shaft 22. The resisting rod 23 is fixedly connected to the side wall of the support plate 2 and is inclined.

[0034] When the aforementioned limit assembly is in operation, after the pipe is placed on the two rollers 6, the cylinder 3 is activated. The cylinder 3 extends and retracts, causing the included angle between the two rollers 6 to gradually decrease through the connecting piece 4. As the cylinder 3 extends and retracts, the included angle between the two rollers 6 decreases, and the top plate 10 will descend with the connecting piece 4. When the top plate 10 descends, the horizontal plate 9 descends as well. When the horizontal plate 9 descends, it drives the connecting rod 12 to descend. When the connecting rod 12 descends, the rotating shaft 22 will descend. When the rotating shaft 22 descends, the first spring 11 elastically contracts and pulls the connecting rod 12 to move closer to the cylinder 3. The rotating shaft 22 will gradually move closer to the cylinder 3 along the side wall of the resisting rod 23 instead of descending directly. When the connecting rod 12 descends and moves closer to the cylinder 3, it drives the fixed rod 13 and the arc rod 14 to move synchronously, so that the four fixed rods 13 move closer to the cylinder 3 while descending.

[0035] If the maximum diameter of the pipe that can be inserted between the arc-shaped rods 14 and the two rollers 6 when the cylinder 3 is not extended or retracted is X, when the diameter is X, the angle between the two rollers 6 decreases after the cylinder 3 extends or retracts, and the connecting rod 12 drives the four fixed rods 13 to approach the pipe synchronously during the descent. When the four blocking rods 16 contact the outer wall of the pipe, the cylinder 3 stops. At this time, the four blocking rods 16 will resist the outer wall above and below the horizontal height of the center point of the pipe on both sides, thereby preventing the pipe with a larger diameter from falling off the two rollers 6 with a larger angle after being dragged on the rollers 6 due to large shaking. When the cylinder 3 is not fully retracted, the diameter of the pipe is between Y and X. In this range, the V-groove between the two rollers 6 is larger and can support the pipe with a diameter between Y and X. The gradual extension and retraction of the cylinder 3 indicates that the diameter of the pipe is between Y and X. In the section, the connecting rod 12 will move along the horizontal plate 9 towards the cylinder 3. When the connecting rod 12 moves, it drives the gear 20 to mesh with the rack 21. The rotation of the gear 20 drives the round rod 19 and the double-acting screw 18 to rotate. When the double-acting screw 18 rotates, it drives the two support members 15 to move gradually along the arc rod 14 towards the fixed rod 13 through the two lifting rods 17. The cylinder 3 stops when the blocking rod 16 contacts the outer wall of the pipe. The two support members 15 gradually move towards the fixed rod 13. In order to ensure that the blocking rod 16 can support the outer wall above and below the horizontal height of the center point of the pipe in the section from Y to X, and prevent the pipe from shaking and falling when dragged, the support effect of the pipe is improved. When dragging the pipe, the pipe slides on the roller 6, and the ball bearings 25 at the end of the blocking rod 16 can prevent the blocking rod 16 from rubbing against the pipe and reduce resistance.

[0036] As a further embodiment of the present invention, the barrier bar 16 is slidably connected to the support member 15; the barrier bar 16 is fixedly connected to a second spring 24 for its reset.

[0037] When the above solution is in operation, when the barrier bar 16 contacts the outer wall of the pipe through the ball bearing 25, the barrier bar 16 slides into the support member 15 and squeezes the second spring 24. The second spring 24 buffers the barrier bar 16 and prevents the barrier bar 16 from squeezing the outer wall of the pipe too much.

[0038] As a further embodiment of the present invention, the fixing rod 13 is rotatably connected to a roller 26, the roller 26 being made of rubber.

[0039] When the above scheme is in operation, after the blocking bar 16 slides into the support member 15, the roller 26 contacts the pipe. The roller 26 ensures that the pipe can only be transported back and forth during transportation and will not rotate during transportation, thus preventing the pipe from rotating and affecting the welding process.

[0040] As a further embodiment of the present invention, each side wall of the support member 15 is fixedly connected with a sliding rod 27, and the support member 15 is slidably connected to the arc-shaped rod 14 through the sliding rod 27.

[0041] When the above scheme is in operation, the bidirectional lead screw 18 rotates, which drives the two lifting rods 17 to rise and fall respectively. When the two lifting rods 17 move, they drive the support member 15 to move. The slide rod 27 limits the support member 15.

[0042] As a further embodiment of the present invention, the limiting rod 7 is T-shaped.

[0043] When the above solution is in operation, the T-shaped limit rod 7 can prevent it from falling off.

[0044] As a further embodiment of the present invention, the support plate 2 is provided with a limiting groove 28, and the horizontal plate 9 is slidably connected to the limiting groove 28.

[0045] In operation, the above scheme allows the top plate 10 to rise and fall while the horizontal plate 9 slides within the limiting groove 28.

[0046] As a further embodiment of the present invention, the roller 6 is made of rubber.

[0047] In operation, the rubber roller 6 of the above solution will not scratch the pipe.

[0048] Working principle: First, several support devices are placed at certain intervals on the ground. Then, the pipe is placed above the roller 6. The base plate 1 and the support plate 2 can provide support for the roller 6. The roller 6 supports the pipe that needs to be dragged. The pipe is in contact with the roller 6. During the dragging process, the pipe drives the roller 6 to rotate, which reduces the resistance generated by dragging the pipe during the welding process, facilitates construction, and has a certain distance from the ground, which has a certain protective effect on the pipe and prevents foreign objects from scratching the pipe.

[0049] When cylinder 3 is not extending or retracting, the angle between the two rollers 6 is relatively large, allowing them to support larger pipes. If the pipe diameter is small, cylinder 3 needs to be activated. The extension or retraction of cylinder 3 pulls the bottom ends of the two support rods 5 via connector 4. The pull of connector 4 causes the limiting rod 7 to slide within the limiting block 8, which rotates on the inner wall of support plate 2. At this time, the angle between the two rollers 6 gradually decreases, forming a V-shaped groove. This V-shaped groove accommodates and limits the pipe, preventing it from rolling onto the ground during dragging and also preventing it from being dragged too far. It can fall after slight collisions and shaking during the process. As long as the diameter of the pipe does not exceed Y (Y is the distance between the tops of the two rollers 6), the horizontal height of the center point of the pipe is below the tops of the two rollers 6. The V-shaped groove formed by the two rollers 6 can well accommodate and support the pipe. Since the distance between the two rollers 6 gradually decreases when the cylinder 3 extends and retracts, it can support and accommodate pipes of different sizes, thereby improving the applicability of the entire support device. It has a simple structure, is green and environmentally friendly, can be reused, and is easy to construct. The use of channel steel as the base improves the rigidity and stability of the support, and it is not easy to deform or tip over during use.
