Description

Technical Field

[0001] The present invention relates to the technical field of large-scale concrete pipeline storage and transportation, and more specifically, to a municipal pipeline transportation device and a transportation method. Background Art

[0002] With the continuous development of social economy and the continuous progress of urban modernization, the demand for large concrete pipes with a diameter of more than 2m has increased sharply in various municipal projects, especially urban rain and sewage discharge, tap water transportation and other projects. Large-diameter concrete municipal pipes have many advantages such as strong bearing capacity, strong durability and not easy to damage. In addition, concrete pipes can be well connected with various municipal facilities such as pumping stations and sewage treatment facilities. In the municipal drainage system, large concrete pipes can be used as the main water transmission channel to connect various pumping stations to achieve the lifting and long-distance transportation of sewage or rainwater.

[0003] In the production process of concrete pipes, the most commonly used process is to use a cylindrical steel outer formwork in conjunction with a bottom formwork in the component factory to cast a section of pipe. After casting, the concrete pipe is steam-cured with the formwork. The steaming time is generally 6-12 hours. When the concrete strength reaches 75% or a certain strength, the formwork is removed and transported to the stacking area outside the component factory for routine maintenance.

[0004] During the processing, there are lifting cranes indoors and gantry cranes in the outdoor stacking area of ​​the component factory, but there is currently no equipment that can well complete the connection work of pipeline transportation inside and outside the factory. This is because the formwork needs to be removed before large concrete pipes are transported outside, and the current large concrete pipe steel formwork is generally an integral cylindrical outer formwork. The pipe can only be demolded vertically when the formwork is removed. The concrete pipe after demolding is then transferred from indoors to outdoors by forklifts and manual bundling. There are three difficulties in the above operation. First, the concrete pipe after demolding is in a vertical state and needs to be turned to be laid flat before transportation. Second, the demolding is generally carried out when the concrete reaches 75% strength or less. Due to objective factors such as the large diameter and thick wall of municipal concrete pipes, if conventional pipe clamps are used to clamp the edges and lay them flat, it is very easy to cause irreversible damage to the pipes. Third, due to the process of demolding concrete pipes, large-scale turning machines cannot be used directly for processing. Based on the above reasons, the municipal concrete pipes after demolding are currently transported from indoors to outdoors, and they are still transported manually by rope binding and forklifts.

[0005] Therefore, there is an urgent need to propose a new municipal pipeline transportation device and transportation method that is suitable for the current large-scale municipal concrete pipeline manufacturing process, can automatically complete the pipeline flipping and external transportation, improve the transportation efficiency of municipal concrete pipelines, and save manpower and transportation costs.

[0056] like Figures 1 to 24As shown, the present invention provides a municipal pipeline transportation device, including: a turning mechanism 1, which includes two arc-shaped turning frames 13 arranged at intervals, the arc-shaped turning frames 13 are L-shaped frames with an outer arc surface, the outer periphery of the arc-shaped turning frame 13 includes an outer arc surface 130, a first plane 131 which is horizontal and faces upward, and a second plane 132 which is vertical, the outer arc surface 130 is supported by a plurality of turning frame supporting rollers 11 fixed to the ground; a bearing platform 14 with a horizontal top surface is connected between the two first planes 131, and a pipeline 6 is erected on the bearing platform 14, wherein the center axis of the outer arc surface 130 is the rotation axis of the turning mechanism 1, and when the turning mechanism 1 rotates 90° around its rotation axis, the second plane 132 changes from vertical to horizontal and faces upward; a first rotating mechanism 2, the first rotating mechanism 2 is on A frame structure with a horizontal surface, one end of which is located between the two arc-shaped flip frames 13 and is rotatably connected to the arc-shaped flip frames 13 on both sides, the rotation axis of the first rotating mechanism 2 is parallel to the rotation axis of the flip mechanism 1, and the rotation axis of the first rotating mechanism 2 and the pipeline are respectively located on both sides of the two second planes 132; a slide 4, which includes a horizontal table top 41, the table top 41 is an arc-shaped plate, and its inner wall matches the shape of the pipeline 6, and a plurality of slide beams 42 are connected under the table top 41, and the slide beams 42 are detachably connected to the upper surface of the first rotating mechanism 2, wherein, after the first rotating mechanism 2 drives the slide 4 thereon to rotate 90°, the upper surface of the first rotating mechanism 2 is vertical and faces the pipeline 6, and at this time, the inner wall of the table top 41 is completely fitted with the outer wall of the pipeline 6.

[0057] In the present technical solution, the turning mechanism 1 is fixed and rotated by an arc-shaped turning frame 13 supported by a plurality of turning frame supporting rollers 11 on both sides. Figure 1As shown, since the flip mechanism 1 is cylindrical, in order to make the first plane 131 and the second plane 132 after 90° flipping flush with the ground and reduce the height of the subsequent corresponding receiving device, a first equipment pit 10 can be opened downward from the ground in the factory, and the flip frame supporting roller 11 is set in the first equipment pit 10. The flip frame supporting roller 11 is fixed in the shaft seat in the first equipment pit 10 through a bearing. A toothed belt or a chain group can be set on the outer arc surface 130, and the fixation and controllable rotation are completed by a gear group matched with the transmission. In addition to being supported by the flip frame supporting roller 11, the flip mechanism 1 also needs to be provided with limit rollers and other structures on both sides to avoid the flip mechanism 1 When displacement outside the rotation surface occurs, the arc-shaped flip frame 13 can be regarded as a single frame body welded by a steel structure. The connection measures between the two arc-shaped flip frames 13 are a load-bearing platform 14 and a connection structure 15 under the load-bearing platform 14. Since a rotatable space needs to be provided between the two arc-shaped flip frames 13 for the first rotating mechanism 2, no connection structure is set between the two arc-shaped flip frames 13 within the 90° rotatable range of the first rotating mechanism 2. The first rotating mechanism 2 can freely complete an upward rotation of 90° within the interval between the two arc-shaped flip frames 13. The first rotating mechanism 2 is a strip-shaped plate-shaped frame structure with greater rigidity. The first rotating mechanism 2 horizontally extends out of the flip mechanism 1. The slide 4 can be an electric flat car or other frame with a self-driving function. The slide 4 is translated to the first rotating mechanism 2 under the action of an external force or its own driving force. The slide 4 can be temporarily fixed to the upper surface of the first rotating mechanism 2 by bolts, fixing pins, etc., so as to achieve the purpose of coordinated rotation with the first rotating mechanism 2.

[0058] In this technical solution, if Figure 2 , Figure 3 As shown, the pipe 6 with the outer formwork 61 and the bottom formwork 62 is directly lifted on the bearing platform 14 by the indoor overhead crane equipment. The lifting position of the pipe 6 needs to be the same each time to facilitate the complete contact between the outer wall of the subsequent pipe 6 and the table top 41. After the connection between the outer formwork 61 and the bottom formwork 62 is manually released, the outer formwork 61 is lifted and removed by the overhead crane equipment. In this process, since the concrete outer wall of the pipe 6 needs to be exposed by removing the outer formwork 61, it is impossible to directly complete the conversion between the vertical and horizontal placement of the pipe 6 through the conventional flipping structure, and the concrete strength just after the formwork is removed is generally lower than 75% of the design strength. In order to ensure that the concrete surface is evenly stressed during the flipping process, it is necessary to introduce a support structure to support and limit the pipe 6 during the horizontal placement process to avoid collisions with the pipe 6. The table top 41 in the slide 4 is a curved steel plate processed to adapt to the shape of the pipe 6, and supports the pipe 6 throughout the rotation of the flipping mechanism 1.

[0059] When the pipe 6 is separated from the outer template 61, the first rotating mechanism 2 in the device is in a horizontally extended state, which does not affect the manual work on the carrying platform 14. The slide 4 is driven by its own power or external force to move horizontally to the first rotating mechanism 2 to be fixed. After the outer template 61 is separated from the pipe 6 and the inner and outer surfaces of the pipe 6 are treated, the first rotating mechanism 2 drives the slide 4 thereon to rotate 90° while the flipping mechanism 1 remains stationary. The originally horizontal structural surface of the first rotating mechanism 2 rotates to a vertical one. At this time, the table top 41 is fully fitted with the outer wall of the pipe 6. Then the relative stillness between the first rotating mechanism 2 and the flipping mechanism 1 is maintained, and the flipping mechanism 1 rotates 90° in the opposite direction with its own rotation axis to make the first rotating mechanism 2 return to a horizontal state. After the connection relationship with the first rotating mechanism 2 is released, the slide 4 can travel to the stacking area outside the factory by itself or under the traction of an external force.

[0060] In another technical solution, each of the outer arc surface 130 is circumferentially fixed with a chain 12, and a plurality of the flip frame supporting rollers 11 support the curved surface of the outer arc surface 130 located outside the chain 12. A group of driving gears 111 are arranged under each of the arc flip frames 13, which are meshed with the chain 12, and the rotating shaft of the driving gear 111 is connected to a driving motor 112. When the driving gear 111 rotates axially, the tooth block on it drives the chain 12 to move, driving the arc flip frame 13 to rotate. In this technical solution, Fig.11 As shown, in the first equipment pit 10, a driving gear 111 that matches and meshes with the chain 12 is also provided, and the driving motor 112 completes the transmission of the driving gear 111 through the reducer 113, wherein the chain 12 and the corresponding outer arc surface 130 can be connected by welding or other measures, when the driving gear 111 is stationary, the chain 12 and the driving gear 111 maintain a clamping relationship, the flipping mechanism 1 does not rotate, and there may be no direct connection between the two groups of driving gears 111 corresponding to the two arc-shaped flipping frames 13, and the two groups of driving gears 111 are each rotated by the driving motor 112 and the reducer 113 on the corresponding side to avoid collision with any structure during the subsequent rotation of the flipping mechanism 1, and optionally, the two groups of driving 1 gears 111 can also be driven by a group of driving motors 112 in conjunction with the reducer 113 and the coupling device.

[0061] In another technical solution, the angle between the line between the rotation axis of the first rotating mechanism 2 and the rotation axis of the flipping mechanism 1 and the horizontal is 45°, wherein, after the first rotating mechanism 2 rotates 90° around its own rotation axis and rotates 90° in the opposite direction together with the flipping mechanism 1, the upper surface of the first rotating mechanism 2 remains horizontal and has the same height as before the rotation. In this technical solution, when the first rotating mechanism 2 and the flipping mechanism 1 do not have the same rotation axis, the position of the first rotating mechanism 2 after the two rotations is different from that before the rotation due to the different rotation axes during the two rotations. Fig. 9 As shown in (b), in this solution, the rotation axis of the first rotating mechanism 2 is set in front of the right angle between the first plane 131 and the second plane 132, and the angle between the rotation axis connection line of the first rotating mechanism 2 and the flipping mechanism 1 and the ground is 45°. Under this setting, the height of the first rotating mechanism 2 after two rotations is the same as that before the rotation, which is convenient for the recovery of the slide 4.

[0062] In another technical solution, the first rotating mechanism 2 includes two L-shaped rotating arms 23, the rotating arms 23 include a horizontal rotating arm supporting section 231 and a downwardly inclined rotating arm pushing section 232, a fixed shaft 20 is passed through the bearings on the two rotating arms 23, and the two ends of the fixed shaft 20 are fixedly connected to the arc-shaped flip frames 13 on both sides, and the bottom of the supporting platform 14 is hinged with the ends of a plurality of first actuating cylinders 22, and the other end of the first actuating cylinder 22 is hinged to the rotating arm pushing section 232, wherein, when the first actuating cylinder 22 is extended, the rotating arm supporting section 231 rotates with the fixed shaft 20 as the rotating axis, and the upper surface of the rotating arm supporting section 231 is flush with the second plane 132 and in the same direction after rotation. In this technical solution, Fig.10 , Fig.12 As shown, below the supporting platform 14, there is a connecting structure 15 between the two arc-shaped flip frames 13. The connecting structure 15 can be a steel lattice composed of multiple steel plates. The end of the first actuating cylinder 22 is rotatably connected to a fixed seat 21. The fixed seat 21 is a plate body or a rigid support installed below the connecting structure 15. The rotating arm 23 as a whole can be regarded as a lever with a fixed axis 20 as the rotating axis. When the first actuating cylinder 22 is extended, it pushes the pushing section 232 of the rotating arm, and the rotating arm 23 rotates around the fixed axis 20. The rotating arm supporting section 231 drives the slide 4 thereon to complete a 90° rotation. Between the two rotating arms 23, there are several rotating arm connecting plates 233 connected, which support the first limiting slide groove 25 and other plates.

[0063] In another technical solution, a plurality of second fixing members 26 are fixed to the upper surface of the rotating arm supporting section 231, and a plurality of first fixing members 1321 are fixed to the second plane 132, wherein the first fixing members 1321 correspond to the second fixing members 26 one by one and are cylinders of the same size, wherein when the upper surface of the rotating arm supporting section 231 is rotated to be flush with the second plane 132, the first fixing members 1321 and the matching second fixing members 26 can be matched with each other to wear a strip-shaped fixed slider 27 inside, and in this technical solution, when the rotating arm supporting section 231 completes the rotation, its original upper surface is flush with the second plane 132, and the first fixing members 1321 and the matching second fixing members 26 are aligned with each other. 21 and the second fixing member 26 are a one-to-one matching sleeve or annular structure. When the two are aligned, the fixed slider 27 can be inserted between the two on site. The fixed slider 27, the first fixing member 1321, and the second fixing member 26 form a latch structure. Before the flipping mechanism 1 is flipped 90°, the fixed slider 27 does not bear any force. After the flipping mechanism 1 completes the 90° flip, the fixed slider 27 forms a snap-fitting effect between the first fixing member 1321 and the second fixing member 26. At this time, the flipping mechanism 1 bears the force of the first rotating mechanism 2, the slide 4 and the pipe 6 thereon, avoiding the problem that the first actuator 22 is directly subjected to a large force and it is difficult to perform precise position control.

[0064] In another technical solution, two first limit slide grooves 25 are provided on the first rotating mechanism 2, and the cross-section of the first limit slide groove 25 is U-shaped. The two side plates of the first limit slide groove 25 are upwardly retracted in an eight-shaped shape. A plurality of slide support rollers 7 are arranged at intervals in the first limit slide groove 25, and the two ends of the slide support rollers 7 are connected to the two side plate bearings of the first limit slide groove 25. The slide 4 includes two slide beams 42, and the lower part of the slide beam 42 is matched and sleeved in the first limit slide groove 25 and is rollingly supported by a plurality of the slide support rollers 7. In this technical solution, the slide beam 42 is a beam structure with a certain length, and the lower part of the slide beam 42 can always be slidably inserted between the first limit slide groove 25 or the second limit slide groove 51. When the first rotating mechanism 2 rotates, the slide beam 42 forms a card-embedded relationship with the inner wall of the first limit slide groove 25 to prevent the slide 4 from shifting during the rotation process. Optionally, as Fig.12 , Fig.13 As shown, a blocking plate 24 is installed on the upper surface of the first rotating mechanism 2, and the blocking plate 24 is located at the part of the first rotating mechanism 2 close to its own rotating axis. When the first rotating mechanism 2 rotates upward by 90°, the slide 4 forms a resistance relationship with the blocking plate 24 under the action of its own weight. In the present technical solution, the slide supporting roller 7 directly supports the slide 4, and the movement of the slide 4 can be completed by applying a small thrust to the slide 4.

[0065] In another technical solution, two second limiting slide grooves 51 are also included, and the second limiting slide grooves 51 correspond to the first limiting slide grooves 25 one by one and have the same structure. One end of the second limiting slide groove 51 is flush with and connected to the end of the first limiting slide groove 25, and the other end extends to the outdoor stacking area. In this technical solution, since the slide beam 42 is a long strip of rigid structure, even if there is a gap between the first limiting slide groove 25 and the second limiting slide groove 51, it is only necessary to ensure that the ends of the two are relative and at the same height, and the slide beam 42 can complete the span in the gap. The two second limiting slide grooves 51 are fixed on the ground and extend in a straight line from the factory to the outdoor stacking area. Figure 8 As shown, in order to make the two second limiting slide grooves 51 at the same height as the first rotating mechanism 2, a conveying platform 5 with a certain height and an inclined angle can be constructed under the two second limiting slide grooves 51 to support the two second limiting slide grooves.

A slide driving vehicle 44 with self-driving ability is fixed to the bottom of the slide support frame 43, which can travel on the slide connecting plate 8. In this technical solution, Fig. 20 , Fig.21 As shown, the slide driving vehicle 44 is an electric trolley with self-propelling ability. Multiple driving wheels of the slide driving vehicle 44 travel on the slide groove connecting plate 8. The top surface of the slide driving vehicle 4 is connected to the bottom of the slide support frame 43. Optionally, the slide support frame 43 and the slide driving vehicle 4 can also be connected through a hydraulic actuation structure such as a hydraulic pillow. When the friction between the slide driving vehicle 4 and the slide groove connecting plate 8 is small and the slide driving vehicle 4 is difficult to drive the slide 4, a reaction force can be applied downward to the slide driving vehicle 4 through the hydraulic actuation structure to improve the friction effect between the slide driving vehicle 4 and the slide groove connecting plate 8.
