Description

Technical Field

[0001] This invention relates to a positioning device, specifically a splicing positioning device for prefabricated culverts. Background Technology

[0002] In the field of transportation infrastructure construction, prefabricated culverts have been widely used due to their significant advantages such as fast construction speed, controllable quality, and minimal environmental impact. In the traditional prefabricated culvert installation process, the splicing and positioning of the culvert frame is crucial, but it also faces many challenges.

[0003] On the one hand, due to the complex environment of the construction site, traditional positioning devices are difficult to adjust the height accurately, which makes it difficult to ensure the horizontality and verticality of the culvert during installation, affecting the splicing accuracy and thus reducing the stability and safety of the overall culvert structure.

[0004] On the other hand, when culverts are spliced ​​and positioned, traditional methods rely on manual measurement and simple mechanical assistance, which is not only cumbersome and inefficient, but also highly susceptible to human factors in terms of positioning accuracy. This makes it difficult to meet the requirements of large-scale, high-standard construction, increases construction costs and time, and restricts the further promotion and application of prefabricated culvert technology. Therefore, it is necessary to design a splicing and positioning device for prefabricated culverts to solve this problem. Summary of the Invention

[0009] As a further aspect of the present invention: the supporting member includes a telescopic component, which is mounted on a supporting plate, and the movable end of the telescopic component is connected to a supporting frame, on which a supporting roller is mounted.

[0010] As a further embodiment of the present invention: the lifting mechanism includes a lifting groove, and both the base and the support plate are provided with lifting grooves. A lifting block is slidably installed in the lifting groove. A scissor rod assembly is hinged to the lifting block. The end of the scissor rod assembly away from the lifting block is respectively hinged to the base and the support plate. A power component is installed on the side wall of the lifting groove, and the output end of the power component is connected to the lifting block.

[0011] As a further aspect of the present invention, ball bearings are mounted on the surface of the support roller.

[0012] As a further aspect of the present invention, the height of the adjusting block is lower than the height of the fixed baffle and the movable baffle.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: When positioning and assembling the culvert, the base serves as the basic support structure of the entire device. The guide wheels and guide rails at the bottom facilitate the overall transportation of the culvert. The height of the device needs to be adjusted according to the height of the culvert platform. A power component is set to drive the lifting block to move. When the lifting block moves, it causes the scissor lift assembly to deform. Due to the special structure of the scissor lift assembly, the support plate can achieve lifting and lowering movements, thereby adjusting the support plate to a suitable height and providing a suitable working plane for the subsequent installation of the culvert. The culvert is hoisted above the first and second positioning platforms using a hoisting device. The distance between the fixed and movable baffles is adjusted according to the width of the culvert to ensure that both sides of the culvert fit well with the fixed and movable baffles respectively. The drive unit is activated, and its output end drives the drive shaft to rotate. The connecting unit installed on the drive shaft transmits the power of the drive shaft to the driven shaft, causing the driven shaft to drive the threaded rod to rotate. When the threaded rod rotates, according to the principle of threaded transmission, the mounting block slides symmetrically in the mounting groove. By moving the mounting block, the position of the fixed baffle can be adjusted, cooperating with the first positioning platform to position the culvert placed between the movable and fixed baffles. Initial lateral positioning is performed to accommodate the installation requirements of culverts of different widths. Under the action of the hoisting device, the culvert slowly moves downward until it lands on the support rollers. The movable end of the telescopic component drives the support frame to move. The support frame, through the set support rollers, drives the culvert slowly downward. During the descent, the culvert falls between the movable baffle and the fixed baffle. As the culvert continues to move downward, the bottom of the culvert will contact the adjusting block. Under the action of pressure, the adjusting block moves downward. The movement of the adjusting block causes the pressure column to press down on the pull rope. Since the pull rope is connected to the movable block, the pull rope will pull the movable block to slide in the movable groove. The support rod installed on the movable block is connected to the movable baffle, thereby driving the movable baffle to move. Simultaneously, the elastic component installed on one side of the movable block deforms and generates elastic force when the movable block moves. After the movable baffle moves downward, the splicing surface of the culvert is exposed, allowing the culvert placed on the first and second positioning platforms to be smoothly spliced ​​during installation. At this time, the guide wheel slides on the guide rail, driving the culvert to one side to the splicing point. During the splicing process, under the action of the driving component, the fixed baffle on the second positioning platform pushes the culvert to one side, thereby pushing the culvert from the first positioning platform to the preset culvert platform. After the culvert is disengaged from the device, the elastic force of the elastic component causes the movable block to move in the opposite direction, and the movable baffle returns to its initial position through the pull rope. The reset component set on the side wall of the adjustment groove is connected to the sliding block at the end away from the side wall of the adjustment groove. After the adjustment of the adjustment block is completed, the reset component can return the sliding block to its initial position, facilitating the next adjustment operation. In this way, the position of the movable baffle is precisely adjusted, further accurately fixing the position of the culvert and ensuring the flatness of the splicing surface of the culvert.

[0023] 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.

[0024] Please see Figures 1 to 8As an embodiment of the present invention, a splicing and positioning device for a prefabricated culvert includes a base 1, a lifting mechanism mounted on the base 1, a support plate 4 mounted on the end of the lifting mechanism away from the base 1, the lifting mechanism including a lifting groove, both the base 1 and the support plate 4 having lifting grooves, a lifting block 11 slidably mounted in the lifting groove, a scissor lever assembly 5 hinged to the lifting block 11, the end of the scissor lever assembly 5 away from the lifting block 11 being hinged to the base 1 and the support plate 4 respectively, a power component 12 mounted on the side wall of the lifting groove, the output end of the power component 12 being connected to the lifting block 11, an installation groove being provided on the support plate 4, a first positioning platform 13 mounted on the support plate 4, an installation block 14 symmetrically slidably mounted in the installation groove, a second positioning platform 15 mounted on the installation block 14, a fixed baffle 32 mounted on the second positioning platform 15, and a movable groove being provided on the side wall of the first positioning platform 13. A movable block 16 is slidably installed in the movable groove. A support rod 33 is fixedly installed on the movable block 16. A movable baffle 17 is fixedly connected to the end of the support rod 33 away from the movable block 16. An elastic component 18 is installed on one side of the movable block 16. The end of the elastic component 18 away from the movable block 16 is connected to the top wall of the movable groove. An adjusting block 23 is provided between the first positioning platform 13 and the second positioning platform 15. The height of the adjusting block 23 is lower than the height of the fixed baffle 32 and the movable baffle 17. An adjusting member is connected to the adjusting block 23. The end of the adjusting member away from the adjusting block 23 is connected to the movable baffle 17. A splicing positioning member is installed on the support plate 4. The splicing positioning member is connected to the mounting block 14. Supporting members are symmetrically fixedly installed on the support plate 4. A movable groove is opened on the base 1. Several guide wheels 3 are installed in the movable groove. A matching guide rail 2 is provided at the bottom of the guide wheel 3.

[0025] In this embodiment, when positioning and assembling the culvert 10, the base 1 serves as the basic support structure of the entire device. The guide wheels 3 and guide rails 2 at the bottom facilitate the overall transport of the culvert 10 by the device. The height of the device needs to be adjusted according to the height of the culvert platform. The power component 12 drives the lifting block to move. When the lifting block 11 moves, it causes the scissor lift assembly 5 to deform. Due to the special structure of the scissor lift assembly 5, the support plate 4 can achieve lifting and lowering movements, thereby adjusting the support plate 4 to a suitable height and providing a suitable working plane for the subsequent installation of the culvert 10. The culvert 10 is hoisted above the first positioning platform 13 and the second positioning platform 15 using a hoisting device. The splicing positioning components adjust the distance between the fixed baffle 32 and the movable baffle 17 according to the size of the culvert 10, initially positioning the culvert 10 laterally. Under the action of the hoisting device, the culvert 10 slowly moves downwards until it lands on the supporting components. The supporting components drive the culvert 10 downwards. During the descent, the culvert 10 falls between the movable baffle 17 and the fixed baffle 32. As the culvert 10 continues to descend, its bottom contacts the adjusting block 23. Under pressure, the culvert 10 moves downward. During this process, the adjusting block 23 drives the adjusting component to operate, which in turn drives the movable block 16 to move downward. The movable block 16 then drives the movable baffle 17 to move downward, thus exposing the splicing surface of the culvert 10. At this time, the guide wheel 3 slides on the guide rail 2, causing the culvert 10 to move to one side to the splicing point. During the splicing process, the splicing positioning component continues to drive the second positioning platform 15 to push the culvert 10 to one side, thereby pushing the culvert 10 from the first positioning platform 13 onto the preset culvert platform, improving the installation quality and efficiency of the prefabricated culvert.

[0026] Furthermore, the power component 12 can be a cylinder or an electric push rod, etc., which will not be described in detail here.

[0027] Please see Figures 1-6 As an embodiment of the present invention, the splicing positioning component includes a driving component 27, which is mounted on the side wall of the support plate 4. A driving shaft is fixedly mounted on the output end of the driving component 27. The end of the driving shaft away from the driving component 27 extends into the mounting groove, and the driving shaft is rotatably connected to the side wall of the mounting groove. A driven shaft 29 is symmetrically arranged in the mounting groove. One end of the driven shaft 29 is rotatably connected to the side wall of the mounting groove, and the other end is connected to a threaded rod 31. The end of the threaded rod 31 away from the driven shaft 29 is rotatably connected to the side wall of the mounting groove. The threaded rod 31 is threadedly connected to the mounting block 14. A connecting unit 28 is mounted on the driving shaft, and the end of the connecting unit 28 away from the driving shaft is connected to the driven shaft 29.

[0028] In this embodiment, before splicing the culvert 10, the distance between the fixed baffle 32 and the movable baffle 17 needs to be adjusted according to the width of the culvert 10 to ensure that both sides of the culvert 10 can fit well with the fixed baffle 32 and the movable baffle 17 respectively. The drive unit 27 is started, and its output end drives the drive shaft to rotate. The connecting unit 28 installed on the drive shaft transmits the power of the drive shaft to the driven shaft 29, so that the driven shaft 29 drives the threaded rod 31 to rotate. When the threaded rod 31 rotates, according to the thread transmission principle, the mounting block 14 slides symmetrically in the mounting groove. By moving the mounting block 14, the position of the fixed baffle 32 can be adjusted. In cooperation with the first positioning table 13, the culvert 10 placed between the movable baffle 17 and the fixed baffle 32 is initially positioned laterally to adapt to the installation requirements of culverts 10 with different widths. On the other hand, it ensures the neatness of the splicing surface of the culvert 10 and improves the accuracy of the subsequent splicing of the culvert 10.

[0029] Furthermore, the driving component 27 can be a stepper motor or a servo motor, etc., which will not be described in detail here.

[0030] Furthermore, the connecting unit 28 can be a gear set or a pulley set, etc., which will not be described in detail here.

[0031] Please see Figures 1-6 As an embodiment of the present invention, the adjusting component includes an adjusting groove 24. The supporting plate 4 has an adjusting groove 24. A sliding block 25 is symmetrically slidably installed in the adjusting groove 24. An adjusting rod 21 is hinged to the adjusting block 23. The end of the adjusting rod 21 away from the sliding block 25 is hinged to the adjusting block 23. A guide roller 19 is installed on the first positioning platform 13. A pressure rod 34 is installed at the bottom of the adjusting block 23. A pressure column 20 is connected to the end of the pressure rod 34 away from the adjusting block 23. A pull rope 22 is provided at the bottom of the movable baffle 17. The two ends of the pull rope 22 are respectively connected to the movable block 16 provided in the movable groove. The pull rope 22 is wound around the guide roller. The pressure column 20 is provided on the upper side of the pull rope 22 and contacts the pull rope 22. A reset member 26 is installed on the side wall of each adjusting groove 24. The end of the reset member 26 away from the side wall of the adjusting groove 24 is connected to the sliding block 25.

[0032] In this embodiment, the movement of the adjusting block 23 causes the pressure column 20 to press down on the pull rope 22. Since the pull rope 22 is connected to the movable block 16, the pull rope 22 will pull the movable block 16 to slide in the movable groove. The support rod 33 installed on the movable block 16 is connected to the movable baffle 17, thereby driving the movable baffle 17 to move. At the same time, the elastic component 18 installed on one side of the movable block 16 deforms when the movable block 16 moves, generating elastic force. After the movable baffle 17 moves down, the culvert 10 placed on the first positioning platform 13 and the second positioning platform 15 can be smoothly spliced ​​during the installation process. After the splicing is completed, the device will move away from the spliced ​​culvert 10. After the culvert 10 is removed from the device, the elastic force of the elastic component 18 causes the movable block 16 to move in the opposite direction, and the pull rope 22 drives the movable baffle 17 back to the initial position. The reset piece 26, which is located on the side wall of the adjustment groove 24, is connected to the sliding block 25 at one end away from the side wall of the adjustment groove 24. After the adjustment block 23 is adjusted, the reset piece 26 can return the sliding block 25 to its initial position, which is convenient for the next adjustment operation. In this way, the position of the movable baffle 17 is precisely adjusted, and the position of the culvert 10 is further precisely fixed, ensuring the flatness of the splicing surface of the culvert 10.

[0033] Furthermore, both the elastic component 18 and the reset component 26 can be springs or elastic steel sheets, etc., which will not be described in detail here.

[0034] Please see Figures 1-3 As an embodiment of the present invention, the support member includes a telescopic member 6, which is fixedly installed on the support plate 4. The movable end of the telescopic member 6 is fixedly connected to a support frame 7, and a support roller 8 is installed on the support frame 7. Ball bearings 9 are installed on the surface of the support roller 8.

[0035] In this embodiment, after the culvert frame 10 is positioned on the support roller 8, the telescopic component 6 is activated. The movable end of the telescopic component 6 drives the support frame 7 to move. The support frame 7, through the support roller 8, drives the culvert frame 10 to move slowly downward. The support roller 8 and the ball bearing 9 contact the bottom of the culvert frame 10. The ball bearing 9 can reduce the friction between the support roller 8 and the culvert frame 10. Thus, during the splicing process of the culvert frame 10, the fixed baffle 32 can better push the culvert frame 10 onto the preset culvert platform, which facilitates accurate splicing and positioning of the culvert frame 10 and improves the installation quality and efficiency of the prefabricated culvert.

[0036] Furthermore, the telescopic component 6 can be a hydraulic telescopic rod or a cylinder, etc., which will not be described in detail here.

[0037] The working principle of this invention is as follows: When positioning and assembling the culvert frame 10, the base 1 serves as the basic support structure of the entire device. The guide wheels 3 and guide rails 2 at the bottom facilitate the overall transport of the culvert frame 10. The height of the device needs to be adjusted according to the height of the culvert platform. The power component 12 drives the lifting block to move. When the lifting block 11 moves, it causes the scissor lift assembly 5 to deform. Due to the special structure of the scissor lift assembly 5, the support plate 4 can achieve lifting and lowering movements, thereby adjusting the support plate 4 to a suitable height and providing a suitable working plane for the subsequent installation of the culvert frame 10. The culvert 10 is hoisted above the first positioning platform 13 and the second positioning platform 15 using a hoisting device. The distance between the fixed baffle 32 and the movable baffle 17 is adjusted according to the width of the culvert 10 to ensure that both sides of the culvert 10 can fit well with the fixed baffle 32 and the movable baffle 17 respectively. The drive unit 27 is activated, and its output end drives the drive shaft to rotate. The connecting unit 28 installed on the drive shaft transmits the power of the drive shaft to the driven shaft 29, causing the driven shaft 29 to drive the threaded rod 31 to rotate. When the threaded rod 31 rotates, according to the thread transmission principle, the mounting block 14 slides symmetrically in the mounting groove. By moving the mounting block 14, the position of the fixed baffle 32 can be adjusted to cooperate with the first positioning platform 13, and the culvert 10 placed between the movable baffle 17 and the fixed baffle 32 is initially positioned. The lateral positioning of the step adapts to the installation requirements of culverts 10 with different widths. Under the action of the hoisting device, the culvert 10 slowly moves downward until it lands on the support roller 8. The movable end of the telescopic component 6 drives the support frame 7 to move. The support frame 7 drives the culvert 10 to move downward slowly through the set support roller 8. During the descent, the culvert 10 falls between the movable baffle 17 and the fixed baffle 32. As the culvert 10 continues to move downward, the bottom of the culvert 10 will contact the adjusting block 23. The adjusting block 23 moves downward under pressure. The movement of the adjusting block 23 causes the pressure column 20 to press down on the pull rope 22. Since the pull rope 22 is connected to the movable block 16, the pull rope 22 will pull the movable block 16 to slide in the movable groove. The support rod 33 installed on the movable block 16 is connected to the movable baffle 17, thereby driving the movable baffle 17 to move. Meanwhile, the elastic component 18 installed on one side of the movable block 16 deforms and generates elastic force when the movable block 16 moves. After the movable baffle 17 moves downward, the splicing surface of the culvert 10 is exposed, allowing the culvert 10 placed on the first positioning platform 13 and the second positioning platform 15 to be spliced ​​smoothly during the installation process. At this time, the guide wheel 3 slides on the guide rail 2 to drive the culvert 10 to move to one side to the splicing point. During the splicing process, under the action of the drive component 27, the fixed baffle 32 on the second positioning platform 15 pushes the culvert 10 to move to one side, thereby pushing the culvert 10 from the first positioning platform 13 to the preset culvert platform. After the culvert 10 is removed from the device, the elastic force of the elastic component 18 causes the movable block 16 to move in the opposite direction, and the movable baffle 17 returns to the initial position through the pull rope 22.The reset piece 26, which is located on the side wall of the adjustment groove 24, is connected to the sliding block 25 at one end away from the side wall of the adjustment groove 24. After the adjustment block 23 is adjusted, the reset piece 26 can return the sliding block 25 to its initial position, which is convenient for the next adjustment operation. In this way, the position of the movable baffle 17 is precisely adjusted, and the position of the culvert 10 is further precisely fixed, ensuring the flatness of the splicing surface of the culvert 10.
