Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of municipal pipeline construction, in particular to a self-adaptive leveling support frame for municipal pipeline laying. BACKGROUND

[0002] Municipal pipelines are lifelines of urban infrastructure, referring to underground and overhead pipeline systems for transporting water, gas, heat, sewage, rainwater, electricity, communication and other essential media for urban operation. The core function is to realize safe, efficient and stable transportation of media, support normal operation of urban residents' life, industrial production and public services, and is an important guarantee for sustainable development of cities. Pipeline installation is the core link of laying, which needs to ensure accurate pipeline position and reliable interface sealing. The leveling support frame for municipal pipeline laying is a key structural device for supporting pipelines and adjusting their levelness and perpendicularity in municipal pipeline engineering, and is one of the core equipment to ensure stable operation of pipeline systems and meet design requirements.

[0003] The existing self-adaptive leveling support frame for municipal pipeline laying still has some problems. For example, a pipeline laying construction equipment and method (publication number: CN116951174A) is disclosed in a Chinese patent. Although this patent technology can level the support assembly for supporting the pipeline when used in a base pit with uneven bottom wall, the flange connection of multiple pipelines can be aligned at this time, thereby facilitating the connection of the pipelines, the ball hinge as the core rotating part of the support frame directly affects the levelness and safety of the pipeline through the stability of the friction and locking state. The role of the counterweight structure is to offset the inclination caused by the pipeline load by increasing the self-weight. If the friction is too large to allow flexible adjustment of the ball hinge, it will weaken the effect of the counterweight. Insufficient friction will cause the ball hinge to slide under load, causing the support frame to shake, threatening the connection sealing and operation safety of the pipeline. Therefore, the present application provides a self-adaptive leveling support frame for municipal pipeline laying to solve the problems in the above background technology. SUMMARY

[0004] (I) Technical problems solved

[0005] In view of the deficiencies of the prior art, the present application provides a self-adaptive leveling support frame for municipal pipeline laying, which solves the problem that the ball hinge as the core rotating part of the support frame directly affects the levelness and safety of the pipeline through the stability of the friction and locking state. The role of the counterweight structure is to offset the inclination caused by the pipeline load by increasing the self-weight. If the friction is too large to allow flexible adjustment of the ball hinge, it will weaken the effect of the counterweight. Insufficient friction will cause the ball hinge to slide under load, causing the support frame to shake, threatening the connection sealing and operation safety of the pipeline.

[0006] (II) Technical solutions

[0007] To achieve the above object, the present application is realized by the following technical scheme: a self-adaptive leveling support frame for municipal pipeline laying, comprising a support, a leveling structure is arranged at the upper part inside the support, four fixed grooves are arranged at the four corners of the lower end surface of the support, and an insertion structure is fixedly connected to the inner wall of each fixed groove;

[0008] The leveling structure comprises two ball sleeve seats, a spherical groove is arranged between the two ball sleeve seats, a ball is arranged inside the two spherical grooves, an extension plate is fixedly connected to the lower side of the outer side wall of the ball sleeve seat, a plurality of rolling balls are rotatably connected to the lower side of the inner side wall of each spherical groove, a plurality of first channels are arranged at the center of the inner side wall of each spherical groove, a second channel is fixedly connected to the inner side wall of the first channel away from the center of the ball, an electric telescopic rod is arranged inside each second channel, a friction block is fixedly connected to the output end of the electric telescopic rod inside each first channel, an installation groove is arranged at the center of the outer side wall of the ball, a wear-resistant layer is fixedly connected inside the installation groove, a first hook is fixedly connected to the center of the lower end surface of the ball, a second hook is hung outside the first hook, and a counterweight is fixedly connected to the lower end surface of the second hook.

[0009] Preferably, a flat surface is arranged at the center of the lower end surface of the counterweight, which facilitates the placement of the counterweight according to the flat surface.

[0010] Preferably, a support structure is fixedly connected to the center of the upper end surface of the ball, the support structure comprises a first connecting rod, a base is fixedly connected to the center of the upper end surface of the first connecting rod, a storage groove is arranged at the center of the upper end surface of the base, a circular table is rotatably connected inside the storage groove, the upper end of the circular table penetrates through the storage groove to the upper end of the base, and a base plate is fixedly connected to the end portion, a cylinder body is fixedly connected to the upper end surface of the base plate, a piston is slidably connected to the upper part inside the cylinder body, the upper end of the piston penetrates through the cylinder body to the upper end of the cylinder body, and a connecting seat is fixedly connected to the end portion, an arc-shaped groove is arranged at the center of the upper end surface of the connecting seat, and a rubber pad is fixedly connected inside the arc-shaped groove. First, preliminary damping is performed through the rubber pad to reduce the impact of vibration on the equipment, prevent the use of the leveling structure from being affected, and improve the precision of equipment use.

[0011] Preferably, a groove is arranged at each of the four corners of the lower end surface of the connecting seat, a second guide rod is fixedly connected to the upper end surface of the base plate below the four grooves, and the upper end of each of the four second guide rods is slidably connected inside the four grooves. During the process of rising and falling of the connecting seat, the four grooves are respectively slid outside the four second guide rods, thereby improving the stability of the rising and falling of the connecting seat.

[0012] Preferably, the base has discs at the upper ends of both the front and rear ends and at the upper center of both side walls. Each of the four discs has a threaded rod fixedly connected to one end near the base. The four threaded rods pass through the front and rear end faces and side walls of the base and extend into the storage tank. The ends of the threaded rods are attached to the outer wall of the truncated cone. When the base plate is rotated according to the direction of the pipe, the base plate drives the truncated cone to rotate. When the arc-shaped groove is aligned with the direction of the pipe, the four discs are rotated in the forward direction. The four discs drive the four threaded rods to rotate, causing the four threaded rods to move synchronously into the storage tank. After the ends are attached to the truncated cone, the friction between them is increased, preventing the truncated cone from rotating again and facilitating the adjustment of the direction of the arc-shaped groove according to the direction of the pipe.

[0013] Preferably, an air valve is fixedly connected to the lower center of one side wall of the cylinder. Air is supplied to the inside of the cylinder through the air valve. The air compresses the piston and moves it upward. When the pipeline vibrates, the piston compresses the air inside the cylinder to buffer the vibration and reduce the impact of the vibration on the equipment.

[0014] Preferably, taking one of the insertion structures as an example, the insertion structure includes a second hydraulic cylinder, the output end of which is fixedly connected to a ground plug. A base plate is slidably fitted on the outer wall of the ground plug. A limiting bolt is provided at the center of one side wall of the base plate. One end of the limiting bolt passes through the base plate and extends into its interior, while the other end is attached to the outer wall of the ground plug. Four second hydraulic cylinders push four ground plugs out of four fixing slots, causing the four fixing slots to insert into the ground. Depending on the ground level, the depth to which the four ground plugs are inserted into the ground varies. Then, by pushing the four base plates downwards and placing them against the ground, a screwdriver is used to rotate the four limiting bolts. The ends of the four limiting bolts are attached to the side walls of the four ground plugs, which facilitates the four base plates being attached to the ground to reduce pressure and prevent them from penetrating deeper into the ground, thus ensuring initial stability.

[0015] Preferably, hubs are provided at the lower ends of both sides of the bracket, and first hydraulic cylinders are fixedly connected to the center of the lower inner wall of the bracket on both sides. The output ends of the first hydraulic cylinders are fixedly connected to the lower end surface of the extension plate. First guide rods are fixedly connected to the four diagonal points of the upper end surface of the bracket. The four first guide rods pass through the lower end surface of the extension plate and extend to the upper end of the extension plate, and the ends are fixedly connected to the top plate. By controlling the extension of the two first hydraulic cylinders, the two first hydraulic cylinders push the extension plate to move upward, and the extension plate moves upward along the four first guide rods, which drives the ball sleeve seat to move upward.

[0016] (III) Beneficial Effects

[0017] This invention provides an adaptive leveling support frame for municipal pipeline laying. It has the following advantages:

[0018] 1. In this invention, the weight of the counterweight pulls the first connecting rod opposite the first hook to the top. During the rolling process of the ball, the sliding friction between the ball and the spherical groove is converted into rolling friction, which greatly reduces the friction force and improves the flexibility of angle adjustment. Then, by controlling the extension of multiple electric telescopic rods, the multiple electric telescopic rods push multiple friction blocks to move along multiple first channels to the inside of the spherical groove, so that the multiple friction blocks are attached to the outer surface of the wear-resistant layer. The friction blocks are attached to the anti-slip texture on the wear-resistant layer. The multiple electric telescopic rods apply pressure to the multiple friction blocks to increase the friction force, prevent the wear-resistant layer and the ball from rotating, increase stability, and prevent external influences from causing shaking.

[0019] 2. In this invention, the four insertion structures are activated, and the four second hydraulic cylinders push the four ground inserts out of the four fixing slots, so that the four fixing slots are inserted into the ground. Depending on the different levels of the ground, the depth of the four ground inserts inserted into the ground is also different. Then, by pushing the four base plates downwards and putting them against the ground, the four limiting bolts are turned with a screwdriver. The ends of the four limiting bolts are attached to the side walls of the four ground inserts, which makes it easier to put the four base plates against the ground to reduce pressure and ensure that they will not go deeper into the ground again, thus ensuring initial stability.

[0020] 3. In this invention, air is supplied to the cylinder through a valve. The air compresses the piston and moves it upward. When the pipeline vibrates, the vibration is initially damped by a rubber pad, and then the piston compresses the air inside the cylinder to buffer the vibration, thereby reducing the impact of vibration on the equipment, preventing it from affecting the use of the leveling structure, and improving the accuracy of the equipment.

[0021] 4. In this invention, the base plate is rotated according to the direction of the pipe, and the base plate drives the frustum to rotate. When the arc groove is aligned with the direction of the pipe, the four discs are rotated in the forward direction. The four discs drive the four threaded rods to rotate, so that the four threaded rods move synchronously into the storage tank. After the ends are attached to the frustum, the friction between them is increased, preventing the frustum from rotating again and facilitating the adjustment of the direction of the arc groove.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1:

[0034] like Figures 1-6 As shown, this embodiment of the invention provides an adaptive leveling support frame for municipal pipeline laying, including a support 1. A leveling structure 3 is provided at the upper part of the support 1. Fixing grooves 8 are provided at the four opposite corners of the lower end face of the support 1. Insertion structures 9 are fixedly connected to the inner walls of the four fixing grooves 8.

[0035] like Figure 1 , 2As shown in Figures 3 and 6, the leveling structure 3 includes two ball-shaped bases 301, with a spherical groove 304 between them. A sphere 303 is located inside each of the two spherical grooves 304. An extension plate 302 is fixedly connected to the lower part of the outer wall of each ball-shaped base 301. Multiple ball bearings 312 are rotatably connected to the lower part of the inner wall of each of the two spherical grooves 304. Multiple first channels 308 are located at the center of the inner wall of each of the two spherical grooves 304. A second channel is fixedly connected to the inner wall of each of the multiple first channels 308 located away from the center of the sphere 303. 309, each of the multiple second channels 309 is equipped with an electric telescopic rod 310, and each of the multiple first channels 308 has a friction block 311 fixedly connected to the output end of the multiple electric telescopic rods 310. An installation groove 306 is provided at the center of the outer wall of the sphere 303, and a wear-resistant layer 307 is fixedly connected inside the installation groove 306. A first hook 313 is fixedly connected at the center of the lower end face of the sphere 303, and a second hook 314 is hung on the outside of the first hook 313. A counterweight block 315 is fixedly connected to the lower end face of the second hook 314.

[0036] A flat surface 305 is provided at the center of the lower end face of the counterweight 315 to facilitate the placement of the counterweight 315 according to the flat surface 305.

[0037] like Figure 1 , 2 As shown in Figures 3 and 4, a support structure 2 is fixedly connected to the center of the upper surface of the sphere 303. The support structure 2 includes a first connecting rod 204. A base 205 is fixedly connected to the center of the upper surface of the first connecting rod 204. A storage groove 206 is formed at the center of the upper surface of the base 205. A frustum 207 is rotatably connected inside the storage groove 206. The upper end of the frustum 207 passes through the storage groove 206 and extends to the upper end of the base 205. A base plate 210 is fixedly connected to the end of the frustum 210. The upper surface of the base plate 210 is fixedly connected to... A cylinder body 211 is connected, and a piston 213 is slidably connected to the upper part of the cylinder body 211. The upper end of the piston 213 passes through the cylinder body 211 and extends to the upper end of the cylinder body 211. A connecting seat 201 is fixedly connected to the end of the connecting seat 201. An arc-shaped groove 215 is opened at the center of the upper end face of the connecting seat 201. A rubber pad 202 is fixedly connected inside the arc-shaped groove 215. The rubber pad 202 is used for preliminary vibration reduction to reduce the impact of vibration on the equipment, prevent it from affecting the use of the leveling structure 3, and improve the accuracy of the equipment.

[0038] The lower end face of the connector 201 has four opposite corners with grooves 203. The upper end face of the base plate 210 at the lower end of the four grooves 203 is fixedly connected to the second guide rods 214. The upper ends of the four second guide rods 214 are slidably connected to the inside of the four grooves 203. During the process of the connector 201 rising and falling, the four grooves 203 slide on the outside of the four second guide rods 214, which improves the stability of the connector 201 rising and falling.

[0039] Disks 208 are provided at the upper ends of the front and rear ends of the base 205 and at the upper center of the side walls of the base 205. Each of the four disks 208 is fixedly connected to a threaded rod 209 at one end near the base 205. The four threaded rods 209 pass through the front and rear end faces and the side walls of the base 205 and lead to the interior of the storage tank 206. The ends of the four disks 208 are attached to the outer wall of the frustum 207. The base plate 210 is rotated according to the direction of the pipeline. The base plate 210 drives the frustum 207 to rotate. When the arc groove 215 is aligned with the direction of the pipeline, the four disks 208 are rotated in the forward direction. The four disks 208 drive the four threaded rods 209 to rotate. The four threaded rods 209 move synchronously into the storage tank 206. After the ends are attached to the frustum 207, the friction between them and the frustum 207 is increased, preventing the frustum 207 from rotating again. This makes it easy to adjust the direction of the arc groove 215 according to the direction of the pipeline.

[0040] A valve 212 is fixedly connected to the lower center of one side wall of the cylinder 211. Air is supplied to the inside of the cylinder 211 through the valve 212. The air compresses the piston 213 and moves it upward. When the pipeline vibrates, the piston 213 compresses the air inside the cylinder 211 to buffer the vibration and reduce the impact of the vibration on the equipment.

[0041] Hubs 4 are provided at the lower ends of both sides of the bracket 1. First hydraulic cylinders 5 are fixedly connected to the center of the lower inner wall of the bracket 1 on both sides. The output ends of the first hydraulic cylinders 5 are fixedly connected to the lower end face of the extension plate 302. First guide rods 6 are fixedly connected to the four opposite corners of the upper end face of the bracket 1. The four first guide rods 6 pass through the lower end face of the extension plate 302 and extend to the upper end of the extension plate 302. The ends are fixedly connected to the top plate 7. By controlling the extension of the two first hydraulic cylinders 5, the two first hydraulic cylinders 5 push the extension plate 302 to move upward. The extension plate 302 moves upward along the four first guide rods 6, which drives the ball sleeve seat 301 to move upward.

[0042] Example 2:

[0043] like Figure 2 and 5 As shown, this embodiment is based on Embodiment 1:

[0044] Taking one of the insertion structures 9 as an example, the insertion structure 9 includes a second hydraulic cylinder 901. The output end of the second hydraulic cylinder 901 is fixedly connected to a ground plug 902. A base plate 903 is slidably sleeved on the outer wall of the ground plug 902. A limiting bolt 904 is provided at the center of one side wall of the base plate 903. One end of the limiting bolt 904 passes through the base plate 903 and extends into the interior of the base plate 903, and the end is attached to the outer wall of the ground plug 902. The four second hydraulic cylinders 901 push the four ground plugs 902 out of the four fixing slots 8, so that the four fixing slots 8 are inserted into the ground. Depending on the different levels of the ground, the depth to which the four ground plugs 902 are inserted into the ground is also different. Then, by pushing the four base plates 903 downward, they are attached to the ground. Using a screwdriver to turn the four limiting bolts 904, the ends of the four limiting bolts 904 are attached to the side walls of the four ground plugs 902, which makes it easier to attach the four base plates 903 to the ground to reduce pressure and ensure that they will not go deeper into the ground again, thus ensuring initial stability.

[0045] Working principle: When moving, the device is moved by four hubs 4, and the second hook 314 on the counterweight 315 is removed from the first hook 313 to facilitate the device's movement. When in use, the bracket 1 is moved to the position that needs support by the hubs 4, and the four insertion structures 9 are activated. The four second hydraulic cylinders 901 push the four ground plugs 902 out of the four fixing slots 8, so that the four fixing slots 8 are inserted into the ground. Depending on the levelness of the ground, the depth to which the four ground plugs 902 are inserted into the ground is also different. Then, by pushing the four base plates 903 downward, they are placed against the ground. The four limit bolts 904 are turned with a screwdriver, and the ends of the four limit bolts 904 are attached to the side walls of the four ground plugs 902, which makes it easier to place the four base plates 903 against the ground to reduce pressure and ensure that they will not go deeper into the ground again, thus ensuring initial stability.

[0046] The second hook 314 is then hung on the first hook 313, and the counterweight 315 is hung on the lower end of the ball 303. The weight of the counterweight 315 pulls the first connecting rod 204, which is opposite to the first hook 313, to the top. During the rolling process of the ball 303, the sliding friction between the ball 303 and the spherical groove 304 is converted into rolling friction, which greatly reduces the friction force and improves the flexibility of angle adjustment. Then, by controlling the extension of multiple electric telescopic rods 310, the multiple electric telescopic rods 310 push multiple friction blocks 311 to move along multiple first channels 308 towards the inner side of the spherical groove 304, so that the multiple friction blocks 311 are attached to the outer surface of the wear-resistant layer 307. The friction blocks 311 are attached to the anti-slip texture on the wear-resistant layer 307. The multiple electric telescopic rods 310 apply pressure to the multiple friction blocks 311 to increase the friction force, prevent the wear-resistant layer 307 and the ball 303 from rotating, increase stability, and prevent external influences from causing shaking.

[0047] After the connecting seat 201 is kept in a horizontal position, the two first hydraulic cylinders 5 are extended. The two first hydraulic cylinders 5 push the extension plate 302 upward, and the extension plate 302 moves upward along the four first guide rods 6, causing the ball sleeve seat 301 to move upward, thus moving the connecting seat 201 upward. Then, the base plate 210 is rotated according to the direction of the pipeline. The base plate 210 drives the frustum 207 to rotate. When the arc groove 215 is aligned with the direction of the pipeline, the four discs 208 are rotated in the forward direction. The four discs 208 drive the four threaded rods 209 to rotate, thus... Four threaded rods 209 move synchronously into the storage tank 206. After their ends fit against the frustum 207, the friction between them increases, preventing the frustum 207 from rotating again. Then, air is supplied into the cylinder 211 through the air valve 212. The air compresses the piston 213 and moves it upward. When the pipeline vibrates, the rubber pad 202 first provides initial vibration damping, and then the piston 213 compresses the air inside the cylinder 211 to buffer the vibration, reducing its impact on the equipment and preventing it from affecting the use of the leveling structure 3, thus improving the accuracy of the equipment.

[0048] The equipment includes a control panel, which enables the equipment to be started and controlled through a human-machine interface and an electrical control system. Input signal processing converts the operator's instructions into electrical signals, and output signal transmission transmits the control signals to each actuator to achieve the above-mentioned equipment control. This is a commonly used technical solution in existing control systems and will not be elaborated on here. The method of synchronously controlling the two first hydraulic cylinders 5, the four second hydraulic cylinders 901, and the multiple electric telescopic rods 310 is achieved by the main controller using a synchronous control algorithm, such as the synchronous output function of the PLC or the synchronous instructions of the servo controller, to ensure that the two start synchronously. This is also a commonly used technical means in existing control systems and will not be elaborated on here.
