Description

Technical Field

[0001] This invention relates to the field of municipal culvert engineering technology, specifically to an intelligent assembly device for prefabricated components used in municipal culvert engineering. Background Technology

[0002] Municipal culvert engineering is an important component of urban infrastructure construction. A culvert is a water passage or traffic channel buried under roads, railways, embankments, etc., and is usually made of concrete, reinforced concrete, or metal materials. Currently, prefabricated assembled box culverts are being widely promoted and applied, which reduces on-site construction safety risks and economic costs to a certain extent. The intelligent assembly of prefabricated components in municipal culvert engineering is an important development direction in the field of municipal engineering. Through factory prefabrication and intelligent assembly technology, it significantly improves construction efficiency, quality, and safety.

[0003] Referring to Chinese Patent Publication No. CN217839766U, published on November 18, 2022, a mechanized on-site assembly device for precast culverts is disclosed. Compared with traditional on-site assembly processes for precast culverts, this utility model can control the positioning accuracy of precast culvert components, is low in cost, high in efficiency, and reusable. However, during use, although the drive wheels can move within the pre-set trench, if there are stones or other debris in the trench, the drive wheels running over them will cause the assembly device to shake, hindering transportation. Furthermore, since the precast culvert is not positioned during transportation, shaking can cause it to shift on the upper side of the device, further impeding accurate transportation. Therefore, there is room for further improvement.

[0004] Therefore, we propose an intelligent assembly device for prefabricated components used in municipal culvert engineering to address the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent assembly device for prefabricated components in municipal culvert engineering, in order to solve the problems mentioned in the background art. Although the drive wheels can move within the preset trench during use, if there are stones or other debris in the trench, the drive wheels will run over the stones, causing the assembly device to shake, which is not conducive to transportation. Furthermore, the prefabricated culvert is not positioned during transportation, and if it shakes, it will cause the prefabricated culvert to shift on the upper side of the device, which is not conducive to the accurate transportation of the prefabricated culvert.

[0017] Preferably, a connecting block is provided on the lower side of the mounting plate, and the connecting block is rotatably connected to the second support column. The second support column is located on the upper side of the base plate.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] This municipal culvert project uses a prefabricated intelligent assembly device. When the base plate moves in the trench, the irregularly shaped cleaning plate cleans up stones and other debris in the trench, placing the debris on both sides of the trench. This prevents the stones from affecting the movement of the walking components, allowing the base plate to move smoothly. The mounting plate is connected to the upper left side of the base plate via connecting rods and wheels. When the side of the mounting plate rises or falls, the culvert prefabricated body on the upper side of the positioning frame is tilted, facilitating installation. The first and second connecting frames are used to adjust the position of the positioning groove inside the positioning frame, so that the positioning groove fits tightly with the side of the culvert prefabricated body, thus positioning the culvert prefabricated body and facilitating its assembly.

[0025] 1. It is equipped with a sliding rod, a polygonal rod and a polygonal groove. The polygonal rod and the polygonal groove are slidably connected. When the polygonal rod and the polygonal groove are engaged, the connecting screw will be unable to rotate due to the force of the polygonal rod and the polygonal groove, thus limiting the connecting screw.

[0026] 2. It is equipped with a connecting screw, a special-shaped cleaning plate and a second nut. The connecting screw and the special-shaped cleaning plate are slidably connected. When the base plate walks in the trench, the special-shaped cleaning plate will clean up the stones and other debris in the trench, so that the debris is located on both sides of the trench, thereby preventing the stones from affecting the movement of the walking components and facilitating the smooth walking of the base plate.

[0027] 3. It is equipped with a connecting rod, a rotating wheel and a connecting groove. When the hydraulic cylinder works, it will cause the mounting plate to rotate. At this time, the rotating wheel will rotate in the connecting groove to ensure that the mounting plate is connected to the upper left side of the base plate through the connecting rod, the connecting rod and the rotating wheel. When the side of the mounting plate is raised or lowered, the culvert prefabricated body on the upper side of the positioning frame will be in an inclined state to facilitate installation.

[0028] 4. It is equipped with a connecting block, a second support column and a hydraulic cylinder. The upper right side of the base plate is connected to the mounting plate through the connecting block and the second support column, which can support the mounting plate and facilitate stable transmission.

[0029] 5. The device is equipped with a first connecting frame, a positioning slot, and a second connecting frame. The position of the positioning slot inside the positioning frame is adjusted by the first and second connecting frames, so that the positioning slot fits tightly against the side of the culvert precast component body. Then, after the culvert precast component body is placed on the upper side of the platform on the mounting plate, the positioning slot is moved up to make the positioning slot fit completely and tightly against the culvert precast component body, thereby positioning the culvert precast component body and facilitating the assembly of the culvert precast component body.

[0039] 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.

[0040] Please see Figures 1-8 This invention provides a technical solution: an intelligent assembly device for prefabricated components in municipal culvert engineering, comprising: a base plate 1, a walking assembly 2, a support plate 3, a sliding rod 4, a disc 5, a first spring 6, a polygonal rod 7, a polygonal groove 8, a connecting screw 9, an irregularly shaped cleaning plate 10, a first nut 11, a limiting ring 12, a second spring 13, a second nut 14, a first support column 15, a connecting rod 16, a limiting disc 17, a rotating wheel 18, a connecting groove 19, an mounting plate 20, a connecting block 21, a second support column 22, a hydraulic cylinder 23, a round rod 24, an electric telescopic rod 25, a positioning frame 26, a first bidirectional threaded rod 27, a first connecting frame 28, a positioning groove 29, a first limiting rod 30, a second threaded rod 31, a second connecting frame 32, a second limiting rod 33, and a culvert prefabricated component body 34.

[0041] While existing utility models allow the drive wheels to move within a pre-set groove during use, if there are stones or other debris in the groove, the drive wheels may run over the stones, causing the assembly device to shake, which is not conducive to transportation. Furthermore, the precast culvert is not positioned during transportation, and if it shakes, the precast culvert may shift on the upper side of the device, which is not conducive to the accurate transportation of the precast culvert. Therefore, there is still room for further improvement.

[0042] Working principle: When using the intelligent assembly device for prefabricated components in municipal culvert engineering, it should be noted that the walking component 2 is composed of a drive wheel, a support axle and a wheel fork. The drive wheel has a drive source for providing driving force. The walking component 2 is a reference to the comparative patent, so it will not be described in detail. The concrete foundation has grooves inside, and the bottom plate 1 moves in the grooves through the walking component 2.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support plate 3 is provided on the outer side of the walking component 2 located on the lower side of the base plate 1, and a connecting screw 9 is slidably connected inside the support plate 3. The connecting screw 9 is slidably connected to the support plate 3. During assembly, the first nut 11 is first threadedly connected to the connecting screw 9 and the position is adjusted. Then, the limiting ring 12 and the second spring 13 are successively put on the outer side of the connecting screw 9. Then, the connecting screw 9 is slidably connected to the lower side of the support plate 3. Finally, the second nut 14 is threadedly connected to the connecting screw 9. At this time, the second nut 14 plays a limiting role for the connecting screw 9, which makes it easy for the connecting screw 9 to play a limiting role. At this time, the irregular cleaning plate 10 and the groove are almost tightly fitted.

[0044] When there are stones in the trench, the irregular cleaning plate 10 will clean the stones and other debris in the trench, placing the debris on both sides of the trench, thereby preventing the stones from affecting the movement of the walking component 2 and facilitating the smooth movement of the base plate 1. In addition, if the inside of the trench is inclined, the irregular cleaning plate 10 will move upward. At this time, the second spring 13 will undergo elastic deformation, causing the connecting screw 9 and the irregular cleaning plate 10 to move up and down below the support plate 3. The polygonal rod 7 will move upward within the support plate 3 along with the sliding rod 4. At this time, the first spring 6 will also undergo elastic deformation. After the terrain returns to flatness, the first spring 6 and the second spring 13 will return to their elastic deformation, thereby restoring the irregular cleaning plate 10 to its original shape. In addition, if there is concern that the edge of the irregular cleaning plate 10 will rub against the trench, the edge of the trench can be ground and adjusted to make the side edge of the irregular cleaning plate 10 arc-shaped or inclined.

[0045] It should be noted that the polygonal rod 7 and the polygonal groove 8 are slidably connected. When the polygonal rod 7 and the polygonal groove 8 are engaged, the connecting screw 9 will be unable to rotate due to the force of the polygonal rod 7 and the polygonal groove 8, thus limiting the connecting screw 9 and keeping the irregular cleaning plate 10 and the walking assembly 2 in a parallel state. When the connecting screw 9 is moved up and down manually, the slide bar 4 will also keep the polygonal rod 7 slidably connected to the polygonal groove 8 due to the presence of the first spring 6, thus ensuring a relatively stable connection.

[0046] like Figure 1... Figure 2 , Figure 5 and Figure 8 As shown, before placing the precast culvert body 34 on the platform above the mounting plate 20, first position all the positioning slots 29 at the inner edge of the positioning frame 26. The first bidirectional threaded rod 27 and the second threaded rod 31 are rotatably connected to the positioning frame 26, and the first bidirectional threaded rod 27 and the second threaded rod 31 are respectively fixedly connected to the output shaft of the servo motor. The servo motor is also fixedly connected to the positioning frame 26. Start the electric telescopic rod 25 to move the positioning frame 26 down above the mounting plate 20. Since the positioning frame 26 is provided with a round rod 24 on the lower side, the round rod 24 plays a limiting role on the positioning frame 26, making it convenient for the positioning frame 26 to move vertically.

[0047] When the positioning frame 26 moves down, the height of the positioning groove 29 will be lower than the height of the upper platform of the mounting plate 20, which makes it easier to place the culvert precast body 34 on the upper side of the mounting plate 20. When the servo motor fixedly connected to the first bidirectional threaded rod 27 is started, the first bidirectional threaded rod 27 will rotate. At this time, the two first connecting frames 28 will move towards each other inside the positioning frame 26, and the positioning groove 29 will move towards each other inside the positioning frame 26, so that the first connecting frame 28 moves back and forth inside the positioning frame 26. At this time, the positioning groove 29 will also move with the movement of the first connecting frame 28. The first connecting frame 28 is slidably connected to the first limiting rod 30. The first limiting rod 30 plays a limiting role on the first connecting frame 28, which facilitates the horizontal movement of the first connecting frame 28.

[0048] Similarly, starting the servo motor fixedly connected to the second threaded rod 31 will cause the second threaded rod 31 to rotate. At this time, the two second connecting brackets 32 will move towards each other inside the positioning frame 26, causing the second connecting brackets 32 to move left and right inside the positioning frame 26. At this time, the positioning groove 29 will also move with the movement of the second connecting brackets 32. The positioning groove 29 will move towards each other inside the positioning frame 26, and the second connecting bracket 32 ​​will be slidably connected to the second limiting rod 33. The second limiting rod 33 will limit the movement of the second connecting bracket 32, making it convenient for the second connecting bracket 32 ​​to move horizontally.

[0049] Place the culvert precast component body 34 on the upper side of the platform on the mounting plate 20, start the servo motor on the side of the first bidirectional threaded rod 27 to make the positioning groove 29 fit tightly with the front and rear sides of the culvert precast component body 34, start the servo motor on the side of the second threaded rod 31 to make the positioning groove 29 fit tightly with the left and right sides of the culvert precast component body 34, then stop the hoisting, place the culvert precast component body 34 on the upper side of the mounting plate 20, start the electric telescopic rod 25 to make the upper side of the positioning groove 29 fit tightly with the culvert precast component body 34, thereby completing the positioning of the culvert precast component body 34.

[0050] like Figure 1, Figure 6 and Figure 7 As shown, when the culvert precast component body 34 is placed on the upper side of the mounting plate 20, if one side of it is to be raised or lowered, the hydraulic cylinder 23 is activated. The upper side of the hydraulic cylinder 23 is equipped with rollers, which push the side of the mounting plate 20 to rise. Since the lower side of the mounting plate 20 is equipped with a connecting groove 19, and the inside of the connecting groove 19 is equipped with a rotating wheel 18, when one side of the mounting plate 20 is raised, the rotating wheel 18 will rotate in the connecting groove 19 and its position will change. The rotating wheel 18 will also move the connecting rod 16 upward. When one side of the mounting plate 20 is lowered, the connecting rod 16 will move downward in the first support column 15, and the limiting plate 17 on the side of the connecting rod 16 will provide support.

[0051] In addition, the other side of the mounting plate 20 is fixedly connected to the connecting block 21, and the connecting block 21 is rotatably connected to the second support column 22, so that the mounting plate 20 can rotate and the connection is stable. If you want to lift the other side of the culvert precast body 34, since the bottom plate 1, the walking component 2 and the irregular cleaning plate 10 in the device are symmetrically arranged, you only need to turn the device in the opposite direction and then move the device in the trench.

[0052] This is the entire working process of the intelligent assembly device for prefabricated components used in the municipal culvert project. Any content not described in detail in this manual is existing technology known to those skilled in the art.

[0053] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
